　　Specification of slurry purification separator for injection pile and sediment separator for precision drilling pile

　　The sediment separator is mainly used for circulating water in pile driving, which can filter out 98% of sand and greatly reduce the possibility of drilling being stuck. It can speed up our construction process. It also greatly reduces the amount of mud to be processed in the later stage of the project. The turbid mud from the sediment separator can be recycled for pile driving, and the dry materials are mainly fine sand and small particle stones. Dry materials can be used for backfilling.

　　Generally, 2-3 people operate 1-2 units, and the operation of the box filter press is simple, but the labor intensity is high and the operation is harsh. Generally, two people operate 1-2 units, and the treatment of the operators is relatively good. Based on the above comparison, using a centrifuge can save you a lot of labor costs. Among them, the fine screen plate adopts a composite polyester strip seam screen, which is not only corrosion-resistant, but also has a lower dosage (floc agent) compared to the frame. The advantages of sand washing and sludge dewatering equipment are: (1) power: the centrifuge is a continuous process for sludge dewatering. In a preferred embodiment of closed and automatic operation, the static water tank 5 in the secondary filtration water tank and the fine sand vibrating dewatering screen 4 are respectively connected to a three-way flow control valve 41 through an intermediate pipe, and the construction mud separation equipment is a convenient and fast construction mud separation equipment. Currently, the method of treating construction mud is generally to dump the mud into the mud tank. Let it settle naturally, and also use tank trucks to transport and dump the mud, which are relatively primitive and efficient. They are also compared to the specifications of the slurry purification separator for injection piles and the sediment separator for drilling piles.

　　Working principle of drilling fluid centrifuge:

　　The drilling fluid centrifuge is driven by two motors. The main motor drives the drum and differential housing to rotate through a belt, while the auxiliary motor drives the screw after variable speed through the differential. This causes the drum to rotate in the same direction as the screw and has a certain differential speed. The principle of centrifugal settling is used to separate the drilling suspension. The suspension enters the drum through the discharge hole of the screw pusher from the feed pipe. Under the action of centrifugal force, solid particles are pushed towards the inner wall of the drum and discharged through the blades on the screw pusher to the slag discharge outlet at the small end of the drum. The liquid phase overflows through the overflow hole at the large end of the drum. Continuously cycling in this way to achieve the goal of continuous solid-liquid separation, the slurry purification separator of the injection pile is refined, and the sediment separator of the drilling pile is standardized.
