Recommend you go to "Xi'an Zhengdao Energy" to see! At present, many domestic manufacturers of mud-water separation system manufacturers, but most of them are used in mining, oil drilling industry, but to shield tunneling machine supporting mud-water separation system manufacturers are not many, "Xi'an Zhengdao Energy" mud-water separation system in the field of shield there have been a number of successful supporting the field cases, the separation effect is also wrong!
Shield mud water separation system equipment, mainly by the mud screening system equipment and cyclone separation equipment. Specifically including mud vibrating screen and sand removal cyclone separation system, specifically according to the site environment, the viscosity of the drill cuttings mud density and other important parameters for reference, to customize the configuration of mud and water separation equipment and systems! Comparison of cost savings!
Zhengdao Energy shield mud and water separation process:
Mud separation and treatment of the role of the separation system is to shield cutting soil and sand formed in the mud and water particle separation and treatment, and then pump the recycled mud into the adjustment tank. It is more suitable to use vibrating screen as the first level of separation, and the function of vibrating screen is to pre-treat the mud and water, and remove the coarse particles such as agglomerates and lumps. The separation of coarse particles adopts multi-layer vibrating screen to meet the grading of particulate matter,? Different sizes of particles through the vibrating screen of different mesh mesh processing to meet the requirements of the field use of slurry particles, the treatment process is greater than the mesh mesh particles are excluded from the system, after the screen filtered slurry flows into the sedimentation tank.
Cyclone treatment system, mainly composed of sand removal and mud removal two parts, the main function is to vibrating screen separation of fine and medium particles of slurry once again for refinement of the treatment, one by one to reduce the slurry particle size, in order to achieve the site cyclone separation, solid phase control. The working principle of the cyclone is based on the centrifugal force generated by hydrodynamic high-speed rotation to achieve the purpose of treatment, the use of cyclone pumps in the rotating process of the cyclone to generate negative pressure, forcing the fine particles suspended inside the cyclone, centrifugal effect of the spiral upward, through the upper overflow port by the negative pressure extrusion, the slurry in the coarse particles of the gravitational force of self gravity, falling into the lower overflow port of the slurry disposal tank. Cyclone different inner diameter and neck length ratio and different working pressure, decide the cyclone processing effect and processing capacity.
