The KD-200 mud treatment system is used for shield tunneling slurry separation

Xi’an KOSUN KD-200 mud treatment system is mainly composed of a shale shaker, desilter, cone tank, slurry distributor, and electrical control equipment.

The KD-200 mud treatment system from Xi’an KOSUN is capable of separating larger solid particles from the slurry, reducing the solid content. The slurry processed by this system can then enter the next-level treatment equipment such as a centrifuge or filter press.

The KD-200 mud treatment system adopts a modular design. It consists of a shale shaker, desilter, cone tank, and slurry distributor. The slurry enters the screening system through the slurry distributor and undergoes step-by-step treatment on the coarse screen mesh of the vibrating screen, desilter, and fine screen mesh of the vibrating screen. This effectively separates the sand, stones, and other excavated materials carried in the slurry, removing larger solid particles from the tailings and reducing the solid content of the slurry. The slurry processed by this system can then enter the next-level treatment equipment such as a centrifuge or filter press.

Xi’an KOSUN specializes in providing solid-liquid separation equipment, widely used in various fields such as oil drilling mud treatment, drilling waste management, oily sludge treatment, construction slurry treatment, shield tunneling slurry separation, subway muck treatment, and sedimentation pond coal slurry treatment.

Mud-water separator for mud-water balance shield machine

There are two types of subway shield machines: earth pressure balance shield machine and mud-water balance shield machine. Among them, the earth pressure balance shield machine does not need to separate the mud and water. Its essence is to excavate the soil, and the mud and water balance shield machine needs to separate the mud and water.

The principle of the mud-water balance shield machine is to stir the relatively moist soil at the front end of the shield into mud, and then pump out the mud to form a tunnel. The extracted mud needs to be separated from mud and water for environmental protection, and the water in it needs to be reused.

The mud-water separation needs to use a mud-water separator. The mud-water separator is divided into three layers, and sieves out the stone clods of different particle sizes, and then performs pressure filtration to realize the separation of soil and water. In this way, the pollution caused by the direct discharge of muddy water is avoided, and the reuse of water is also realized, and the separated soil can also meet the standard of safe discharge, so that the waste residue can be properly treated. Compared with the earth pressure shield machine, the structure of the mud-water balance shield machine is more complicated, and the mud-water separator also occupies a large area, so it is relatively less used, but in the wetter strata, such as Shanghai and other coastal areas, generally only can use the mud water Balance shield machine.

The treatment process of the mud water treatment system of the shield machine

According to whether the excavation surface is closed, the shield machine can be divided into two types: closed type and open type. According to the principle of balancing the earth pressure and water pressure of the excavation surface, the closed shield machine can be divided into: earth pressure type and mud water type. According to the excavation method, the open shield machine is divided into: hand excavation, semi-mechanical excavation, and mechanical excavation.

In the shield machine, the mud-water separation treatment is required for the mud-water balance shield machine. The mud-water balance shield machine uses mud-water to resist the water pressure and earth pressure of the excavation surface to maintain the stability of the excavation surface, control the deformation of the excavation surface and the settlement of the foundation; form a weakly permeable mud film on the excavation surface to maintain the water pressure Effective on the excavation face. The effect of the mud-water separation is achieved by the mud-water treatment system related to the shield machine.

The mud pumped by the mud pipeline during the tunneling of the mud-water shield machine is transported to the mud-water separation station for separation:

Through the primary screening, most of the solid stones and mud blocks are separated;
After the first-stage separation, most of the clods above 3mm are separated, and the separated mud flows into the slurry collection tank, and then is pumped to the second-stage cyclone by the mud pump for separation;
The accuracy of the secondary separation is 70~74μm. After the secondary separation, the mud is pumped to the tertiary flow device again for separation ;
The separation accuracy of the three-stage cyclone is 20-25 μm. After the three-stage separation, the mud flows back to the pulping tank, and after pulping, it is transported to the knife excavation by the mud pump for placement.
After the waste slurry is filtered and separated by a filter press as required, the slurry particles larger than 5 μm in the slurry are basically separated, and then the sedimentation can meet the discharge requirements.

The slurry separation system is an indispensable supporting facility in shield construction

The slurry separation system is an indispensable supporting facility in modern shield construction. Shield construction refers to the use of shield tunnel boring machines to excavate tunnels on railways, highways, subways, municipalities, water and electricity and other pipes. With the improvement of shield technology, the selection of equipment and technology of the slurry separation system in shield construction have put forward higher requirements.

The slurry separation system mainly includes a shale shaker, a cyclone screen device and a filter press device, the vibrating screen device and the cyclone screen device are connected, the cyclone screen device and the filter press device are connected, and the connection mode is stacked connection Or connect with conveying equipment. The KOSUN shield slurry separation system can perform different separation treatments according to different particle sizes, make full use of the favorable particles in the excavated soil, improve the self-making capacity of the system, and effectively realize the slurry separation system in the shield tunneling, and the separation latter water is re-injected into the muddy water system for circulation. The equipment can be flexibly adjusted according to different terrain conditions. The convenient construction operation reduces the trouble of the slurry separation system occupying a large area and reduces the pollution of the mud to the environment.

The modern slurry separation system pays more attention to environmental protection in design, and highlights the concept of environmental protection in various aspects such as pulping, slurry mixing, separation equipment selection, and waste discharge. KOSUN’s slurry separation system is built based on the previous construction experience at home and abroad and the high-standard rationalization suggestions put forward by customers. With scientific and technological innovation as the standard, the current situation of low separation level is improved by increasing the configuration standard of the desilting device, so that the separation particle size reaches about 15 microns, which greatly reduces the amount of slurry preparation and reduces engineering costs.

Mud treatment solutions in trenchless construction

In the trenchless construction, a large amount of mud and rock debris are produced. How to deal with the mud? This article will introduce common solutions for mud treatment in trenchless construction. Trenchless construction technology is a kind of underground engineering. Trenchless construction includes tunnels, micro tunnels (MTM), horizontal directional drilling (HDD) and other construction methods, also known as directional drilling, pipe ramming (PR), pipe jacking (PJ), underground drainage, horizontal drilling Boring (Habu) and other methods to install pipes and cables underground with minimal excavation. Large-diameter tunnels, such as tunnel drilling machines (TBM), drilling and blasting technology.

According to different construction methods, choose the appropriate slurry treatment equipment as an excellent slurry treatment solution, including: slurry treatment device (separation device), mud water separation station, mud recovery system, etc.

1. Large-scale tunnel drilling and shield construction (TBM). Due to the large diameter of the shield tunneling machine and the large amount of mud, large-scale slurry separation stations with large processing capacity are generally required. This type of slurry separation station is often through several sets of modularization. The slurry separation system is assembled, and the large-scale slurry separation station is used to treat the shield muddy water, which can process a large amount of 2000-4000 m³/h.

2. For the construction of small tunnels, micro tunnels (MTM), pipe jacking (PJ), etc., as well as the diameter of the pipe jacking machine, a slurry separation system with a processing capacity of 120-250m³/h can be selected.

3. For horizontal directional drilling (HDD construction), horizontal drilling and boring (HAB) construction, it can be matched according to the design of the mud pump processing capacity in the trenchless project or the drag force of the HDD trenchless drilling rig, and the processing capacity is 40- 250m³/h mud recovery system (recycling plant).

The above are three long-term effective non-excavation construction mud treatment programs. The selection of suitable mud treatment equipment for different trenchless projects is a prerequisite for scientific construction.

KOSUN’s Complete Shield Slurry Solid-liquid Separation System

A large amount of mud containing sand and rocks will be produced during the construction of slurry shield and pipe jacking. In order to protect the environment and save water resources, it is necessary to carry out solid-liquid separation treatment on the shield mud. KOSUN can provide a complete set of shield slurry solid-liquid separation system. The main equipment includes: shale shaker, de-sander, desilter, bottom drying screen, slurry supply pump, slurry circulation tank, etc. Slurry shield and pipe jacking are often constructed in cities, and the user’s construction site usually requires small equipment footprint and high treatment efficiency.

With the slurry shield and pipe jacking construction, the slurry is continuously purified through the slurry solid-liquid separation system, and ultrafine particles will continue to accumulate, which will eventually affect the shield and pipe jacking construction. Moreover, after the construction of the shield and the pipe jacking is completed, the waste mud also needs to be dehydrated. At this time, the high-speed large-drum slurry separator decanter centrifuge can play an important role. Through mechanical separation or mechanical and chemical flocculation and separation, the ultrafine particles in the shield slurry can be effectively separated, and the clean water can be discharged for recycling or meeting environmental protection discharge requirements.

Metro Shield Construction Slurry Separation Station

In recent years, with the rapid progress of national urbanization, the construction projects of subways, large-scale water conservancy projects, and underground pipe corridors have developed vigorously. Shield construction technology and underground diaphragm wall construction technology have been widely used. Slurry will be generated during the construction of the above-mentioned projects. The slurry treatment plan mainly adopts two modes of “outbound” and “simple separation”, neither of which can meet the national requirements for environmental protection and clean construction and engineering energy-saving requirements. At present, KOSUN can provide large-scale Slurry Separation Station that meet the shield.

Slurry Separation Station is a special equipment for processing the mud and dregs generated by the tunneling of the shield machine during the construction of the subway shield. It is a necessary equipment for the mud-water balance tunneling equipment. The design and matching of the Slurry Separation Station is mainly determined according to the mud pump flow rate of the shield machine. Since the Slurry Separation Station is a modular design, it can be combined to build a mud station according to the different mud flow rates generated by each project.

KOSUN environmental Slurry Separation Station is mainly used in municipal projects, such as river dredging, underground pipe corridors, black and odorous water treatment, urban subway construction, etc., as well as large infrastructure projects such as water conservancy and hydropower projects, urban rail and high-speed rail tunnel projects, Undersea tunnel engineering, etc.
