System operating procedures of the screw stacking machine. Before working on the screw stacking machine, check: turn on the electrical and pneumatic switches, open the clean valve, check related matters, please follow the following steps: turn on the power switch and energize the central control box. Turn on the air source switch (or turn on the air compressor), deliver air to the host air control box, and adjust the total air pressure to 4 kg. Tighten the mesh belt, adjust the tension and pressure, and adjust the air pressure to 2 ~ 3kg. Start the host machine, adjust the belt speed to 4m/min, start the network with the cleaning pump, and maintain the water pressure of 0.3 ~ 0.5 mpa. Check: Pneumatic components are leaking. Will the air tube bend and cause the air pressure to drop? Are the water pressure and water normal? Is it sensitive and reliable? Is the mesh belt tight and the tube opening blocked? If the belt is misaligned, the deflection mechanism is damaged.
The snail stacker starts the sludge dewatering process, starts the chemical pump, adjusts the pump flow, and extracts the diluted flocculant into the mixer. After 5 minutes, the sludge pump starts and the sludge flow rate is adjusted. The sludge flocculation effect was observed, and the mixing ratio of sludge and flocculant was adjusted to achieve the best flocculation effect. Check whether the water content of the mud cake is acceptable. If necessary, adjust the tension and speed of the mesh belt appropriately. Check that the scraper is clean. Check whether the belt is clean and adjust the water volume and pressure appropriately if necessary. Automatic adjustment is normal regardless of whether the belt is deviated or not, and manual adjustment can be used if necessary. Stop, stop the sludge pump, chemical pump. Keep the washing water and rinse the mesh belt until the mesh belt is completely washed. Stop the main unit and clean the water pump. Loosen the tension mesh belt.
Turn off electric and pneumatic switches and close clean water and chemical control valves. The simple operation process of the screw stacking machine is as follows: Start up: turn on the electrical and gas control switches, open the water, chemical, and sludge control valves, keep the belt tight, start the engine, start the cleaning pump, check whether it meets the work requirements, start the reagent pump, start Mud pump, adjust belt speed. Adjust the flushing water pressure, adjust the dosage of reagents, mix the proportion of mud, and check the discharged mud cake. Stop: stop the mud pump, stop the chemical pump, flush the mesh belt, stop flushing the water pump, stop the main machine, loosen the mesh belt, close the electric and pneumatic switches, close the water, chemicals, and sludge control valves. Maintenance of screw stacking machine: all bearings, calcium-based grease once every half month. Pneumatic control part 30 # injection molding oil cup. The inorganic transmission is replaced every 2000 hours. Maintenance: After each work, clean the sludge on the machine body and do not flush water into the motor control box. Note the air filter water in the three connected airways. Check for loose fasteners. Check if the belt is broken. Check whether the pneumatic components are sensitive and reliable.
1. Stacked Spiral Machine structure
1. Spiral body
The laminated spiral body is composed of a fixed ring, a moving ring, a spiral shaft, a screw rod, a gasket and several connecting plates. The fixed rings are connected together by six screws, and gaskets and moving rings are installed between the fixed rings. Both the fixed ring and the moving ring are made of wear-resistant materials, giving the whole machine a longer service life. The spiral shaft passes between the fixed ring and the moving ring, and the moving ring is hollowly sleeved on the spiral shaft.
2. Spiral shaft
The spiral shaft consists of a shaft and a spiral blade, and the shaft is welded by a shaft and a hollow shaft. Assembly welding is to first weld the shaft and the hollow shaft, then perform rough turning after welding to ensure the coaxiality of both ends of the shaft, and then fully weld the spiral blades to the shaft.
3. Driving device
The drive device is the power source of the equipment. The performance of the driving device will directly affect the performance of the entire machine. For this reason, our company chooses motors with superior performance. The motor protection grade is IP54 and the insulation grade is F class. The motor complies with IEC standards and the power supply is 380V AC/3PH/50 Hz.
4. Filtrate tank
The filtrate tank is welded from plates and is used to collect the filtrate filtered out from the main body of the spirochete. The periphery of the filtrate tank is connected to the frame through screws, and there are flanges on the side of the filtrate tank to facilitate connection with external equipment. .
5. Hybrid power system
The mixing system is mainly used to fully mix the sludge and chemicals to form alum flowers, which then enter the main body of the snail pile for squeezing and dehydration.
Solid-liquid Separation works well and is very Environmentally Friendly
