Concentration and dewatering of the stacked screw sludge dewatering machine: The concentrated sludge moves forward with the rolling of the screw shaft; along the direction of the mud cake outlet, the pitch of the screw shaft gradually decreases, and the gap between the rings gradually changes. Small, the volume of the spiral cavity is constantly shortened; under the action of the back pressure plate at the outlet, the internal pressure gradually increases, and the water in the sludge is kneaded and discharged under the continuous operation of the screw drive shaft, and the solid content of the filter cake continues Elevated to achieve continuous dewatering of sludge.
When this strong pressure acts on the filter plate, it must be ensured that the direction of the pressure is in the same straight line as the center point of the filter plate in the filter chamber, so as to insist that every point of each filter plate can receive a uniform force, so as to prevent Because of the uneven force, the leakage of the filter chamber is formed, and if the force of the filter plate is uneven for a long time, it will constitute the local deformation of the filter plate, and the crack of the filter plate in severe cases. Shanghai Stack Screw Sludge Dewatering Machine The manufacturer constitutes unforeseen damage. As the pressure used on the filter plate, it can also be transmitted to the filtrate through the filter plate, and then increase the kinetic energy of the filtrate, allowing the fluid to pass through the filter cloth faster, appropriately increasing the workload of the equipment, and increasing the efficiency of the equipment.
Stack screw sludge dewatering machine manufacturer The control part of the screw sludge dewatering machine selects system planning and is equipped with active work monitoring function. According to the practical operation of the filter press, the control part is divided into manual operation during equipment commissioning, Active working conditions at work. Protective working conditions at the time of equipment maintenance and protection. Each component has an action interlock function for protection during active work to prevent misoperation.
Before operation, you must understand the manual of the screw-stacking sludge dewatering machine. You must have a certain understanding of the screw-stacking machine to ensure that the screw is sensitive and usable. The prevention and control work is 3-5 minutes. Check whether the equipment is working properly and check the capacity. If the upper limit set by the machine is exceeded, the dewatering time of the sludge machine must be evenly distributed to prevent machine sensation. During the operation of the sludge machine, do not use braking equipment to avoid accidents. Do not place debris on the top cover of the machine.
