What are the structural components of the screw stacking machine and what are the selection methods?

The structure of screw stacker mainly includes screw stacker body, screw shaft, driving device, filtrate tank, mixing system, etc. in terms of model selection, attention should be paid to the problems of filter belt, deviation adjustment system software of roller, belt speed control, etc. the following describes in detail the "structural composition and model selection method of screw stacker".

1、 Structural composition of screw stacker

1. Stacked spirochete

The stacked screw body is composed of a fixed ring, a floating ring, a spiral shaft, a screw, a gasket and several connecting plates. The fixed ring is connected together through six screws. A gasket and a floating ring are installed between the fixed rings. Both the fixed ring and the floating 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 floating ring, And the floating ring is sleeved on the spiral shaft.

2. Spiral shaft

The spiral shaft is composed of a shaft and spiral blades, and the shaft is welded with a hollow shaft. Assembly welding is to weld the shaft and the hollow shaft first, and then rough turn 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. 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, with the protection grade of IP54 and the insulation grade of F. The motor complies with IEC standards and the power supply is 380VAC / 3Ph / 50Hz

4. Filtrate tank

The filtrate tank is welded by plates and is used to collect the filtrate filtered by the screw stack body. The periphery of the filtrate tank is connected with the frame body through screws, and a flange is arranged 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 with the agent to form alum flower, which is sent to the main body of Stachys for pressing and dehydration.

2、 Selection method of screw stacker

1. Filter belt. It is specified that the screw stacker has high compressive strength, bump resistance, corrosion resistance, temperature change resistance and other characteristics. In addition, considering the actual characteristics of sludge, select suitable manual weaving lines to make the filter belt have excellent steam permeability and better blocking characteristics than sludge particles.

2. Deviation adjustment system software of roller. General equipment shall be carried out according to pneumatic equipment.

3. Tension system software of filter belt. General equipment is also operated by pneumatic system. The support force of filter belt is generally 0.3-0.7mpa, and the common value is 0.5MPa.

4. Belt speed control. Sludge with different characteristics has different regulations on belt speed, that is, there is a belt speed control category for all a specific sludge. Within this range, the dewatering system software can not only solve the specific working ability, but also obtain high-quality mud cake.
