What is the structure of the screw stacking machine?

The screw stacking machine is generally composed of screw stacking body, mixing system, filtrate tank, screw shaft, driving device and other structures, and the screw stacking machine also has the advantages of short daily maintenance time and simple maintenance, so the following will introduce the relevant contents in detail.

1、 Structure composition of screw stacking machine

1. Spirochete

The superposed screw body is composed of a fixed ring, a moving ring, a spiral shaft, a screw, a gasket and a number of connecting plates. The fixed ring is connected by six screws, and a gasket and a moving ring are installed between the fixed rings. The fixed ring and the moving ring are made of wear-resistant materials, so that the service life of the whole machine is long. The spiral shaft passes through the middle of the fixed ring and the moving ring, And the floating ring is sheathed on the screw shaft.

2. Screw shaft

The spiral shaft is composed of a shaft and a spiral blade, and the shaft is welded with a hollow shaft. Assembly welding is to weld the shaft and hollow shaft first, and then rough turning is carried out after welding to ensure the coaxiality of the shafts at both ends, and then the spiral blade and shaft are fully welded.

3. Driving device

The driving device is the power source of the equipment, and the performance of the driving device will directly affect the performance of the whole machine. Therefore, our company selects the motor with superior performance, the motor protection grade is IP54, and the insulation grade is f. The motor meets IEC standard, and the power supply is 380VAC / 3Ph / 50Hz

4. Filtrate tank

The filtrate tank is welded by plates, which is used to collect the filtrate filtered by the main body. The filtrate tank is connected with the frame body by screws around, and the side of the filtrate tank is provided with a flange to connect with external equipment.

5. Hybrid system

The mixing system is mainly used to fully mix the sludge with the reagent to form alum flower, and then put it into the main body of screw stacking for pressing and dewatering.

2、 Technical advantages of screw stacking machine

1. The machine is suitable for dewatering of high and low concentration sludge. When dewatering low concentration (2000mg / L) sludge, there is no need to build thickening tank and storage tank, which can reduce the construction cost, phosphorus release and anaerobic odor generation.

2. No clogging, reduce the water consumption, save water, reduce the internal circulation burden caused by the backflow of cleaning water.

3. The electric control cabinet, flocculation mixing tank and dehydration main body are integrated to reduce the floor area and make the installation simple and convenient.

4. The dehydrator is basically in closed operation, and the treatment is stable and timely, so that the odor on site is reduced to * low, and the working environment of workers is improved.

5. Realize automatic 24-hour operation, reduce the labor intensity of operators.

6. The speed of the screw shaft is low, 2-3 revolutions per minute, low power consumption, no vibration and noise on site.

7. Almost all of the body is made of stainless steel, which can prolong the service life. The replacement parts are only spiral shaft and traveling ring, and the service cycle is long.

8. The daily maintenance time is short and the maintenance work is simple.
