The main advantages of the slurry separation equipment of the bored pile

The main advantages of the slurry separation equipment of the bored pile:

1. Purify the mud, effectively control the performance index of the mud, sticking accidents, and make holes.

2. Realize mud recycling and save slurry-making materials. Significantly waste pulp outbound costs and pulp making costs.

3. The equipment effectively separates the soil and slag, and the efficiency of hole making.

4. The closed loop purification of mud and the influence of lower slag water content.

5. The double-layer screen is adopted, and the purification effect is nearly 50% higher than that of the single-layer screen. The operation is convenient, simple and reliable.

6. The processing efficiency is high. The higher the mud concentration, the shorter the single machine mud output time, which can be 15-30 minutes faster.

The mud purification device is suitable for pile foundation engineering (including rotary drilling, percussion drilling, etc.) using mud wall protection and circulating drilling technology, anti-seepage wall engineering (ground wall, double-wheel milling), mud-water balance shield construction and mud water Mud purification and recovery for pipe jacking construction. The reuse rate of waste mud avoids the random discharge of mud, helping customers with construction costs and environmentally friendly construction.

The slurry separation equipment for bored pile is mainly suitable for bridge pile foundations such as railways and highways, municipalities, subways, etc., continuous walls, shields, drilling rigs, pile drivers, oil drilling, construction piling mud separation and dewatering, stone mud dewatering, drilling mud dewatering, Tailings treatment, sand field mud, cave mud, mine mud treatment and other mud separation, etc.

Treatment effect of five-level drilling fluid solids control system equipment

The drilling fluid solids control system is mainly used to remove harmful solid phases such as drill cuttings and recover useful solid phases such as barite. The solids control system is mainly composed of mud tanks, drilling fluid shale shakers, desanders, desilters, drilling fluid centrifuges and other major equipment, as well as auxiliary equipment such as mud pumps, slurry mixing devices, and vacuum degassers.

The mud tank is mainly used to store the mud and is the carrier of the solids control equipment. The mud purified by the solids control equipment enters the various chambers of the mud tank, and is processed according to different equipment, so as to achieve the removal of solid particles, recovery of barite, and purification of the mud.

The general processing flow of the solids control system: The drilling fluid shale shaker is the first-stage treatment equipment in the solids control system, which can remove the larger solid phase in the drilling fluid, and can remove solid particles above 74μm. The vacuum deaerator is used to remove the gas in the mud. It is the second and solid control device in the solids control system. It can quickly and effectively remove the gas contained in the mud. The deaerator is useful for restoring the mud density and preventing potential blowouts. It plays an important role in the occurrence of the danger of well collapse. The solids control equipment ranked at the third level is the drilling fluid desander. The mud treated by the vacuum degasser is transported into the desander through the sand pump. The drilling fluid desilter is used after the desander, which is used to remove the solid phase of 15~44μm to further ensure the performance of the drilling fluid.

In some solids control systems that need to save space, a desander, a desilter, and an underflow screen can be combined to form a drilling fluid cleaner, which can effectively remove solid particles larger than 15μm. In some uncomplicated drilling platforms, it can completely replace the desander and desilter. The final treatment equipment of the solids control system is a drilling fluid centrifuge, which is mainly used to remove solid particles smaller than 7μm and recover barite, with a recovery rate of 95-97%.

The solids control equipment is mainly used for complex well conditions and demanding well conditions. In the actual application process, according to the needs of drilling operations, one of the mud solids control processes can be used in one or more stages.

Advantages of KOSUN pipeline dredging equipment and system

KOSUN pipeline dredging equipment and system has the following advantages:

1. Adequate purification of mud, control of mud index, sticking accidents, and hole making.

2. Effectively separate the soil ballast, make holes, and shorten the cleaning time.

3. Mud recycling, saving slurry materials and construction costs.

4. Closed mud circulation and lower ballast water content, pollution, and outbound transportation costs.

The mud cleaner based on the cyclone separation technology and the secondary shaker technology is the main equipment to realize the pipeline dredging equipment and system technology. Mud cleaner is also called mud purification device or mud desander.

The pipeline dredging equipment and system is produced under the premise of saving labor time, labor cost and water resources. It is mainly used for urban construction and the recycling and reuse of dredging mud from rivers, lakes and seas, which can achieve faster and better urban construction efficiency. It is an environmentally friendly product. The overall efficiency is improved, and it is the current choice for urban construction and dredging mud recovery treatment.
