What are the functions of each part of the stacked screw sludge dewatering machine?


The stacked screw sludge dewatering machine breaks through the traditional filtration mode of the plate and frame type, belt type and centrifugal filter. The equipment is more compact and has a wide range of applications. The disc screw type solid-liquid separator is used for sludge dewatering in various industries. Ideal equipment for work. The advantage is that it saves, saves water, saves electricity, saves labor, also saves floor space, and is simple to operate. The stacked screw sludge dewatering machine is a combination of a fully automatic control cabinet, a flocculation and conditioning tank, a sludge thickening and dewatering body, and a collecting tank. It can achieve flocculation under fully automatic operation and continuously complete sludge concentration and Squeezing and dewatering work will eventually return or discharge the collected filtrate. Let's take a look at the composition of the sludge dewatering machine.


1. Stacked spiral body


The stacked screw body is composed of a fixed ring, a moving ring, a screw shaft, a screw, a gasket, and a number of connecting plates. The fixed ring is connected by six screws. A gasket and a moving ring are installed between the fixed rings. Both the fixed ring and the traveling ring are made of wear-resistant materials, so that the life of the whole machine is longer. The screw shaft is inserted between the fixed ring and the traveling ring, and the traveling ring is hollow on the screw shaft.


2. Spiral shaft


The spiral shaft is composed of a shaft and a spiral blade, and the shaft is welded by the shaft and the hollow shaft. Assembling welding is to first weld the shaft and the hollow shaft, then perform rough turning after welding to ensure the coaxiality of the shafts at both ends, and then weld the spiral blade and the shaft by full welding.


3. Drive device


The drive device is the power source of the equipment. The performance of the drive device will directly affect the performance of the whole machine. For this reason, our company selects a motor with superior performance, the motor protection class is IP54, and the insulation class is F. The motor complies with the IEC standard, and the power supply is 380V AC/3PH/50 Hz.


4. Filtrate tank


The filtrate tank is welded by plates and is used to collect the filtrate filtered by the main body of the stacked screw. The filtrate tank is connected with the frame body by screws, and flanges are provided on the side of the filtrate tank to connect with external equipment. .


5. Hybrid system


The mixing system is mainly used to fully mix the sludge and the medicament to form alum, which is then fed into the main body of the snail for squeezing and dehydration.
