Description
Technical Field
The invention relates to the technical field of filter presses, in particular to a filter press with a mechanical locking device.
Background
The sewage treatment is a process for discharging or reusing the sewage after the sewage treatment, and the sludge dewatering machine is an environment-friendly device for dewatering the sludge generated by the sewage treatment process and is generally divided into a plate-and-frame filter press, a centrifugal sludge dewatering machine, a belt-type sludge dewatering machine, a stacked-screw type sludge dewatering machine and the like. Wherein, the centrifugal sludge dewatering machine is mainly suitable for sludge with large density difference and has large use limitation; the belt filter press is matched with a large amount of medicament, high in price, high in operating cost and not environment-friendly; the stacked screw type sludge dewatering machine has smaller treatment capacity and lower dewatering efficiency than a plate-and-frame filter press. The plate-and-frame filter press is used as the current common dewatering equipment, slurry is directly injected into a filter chamber formed by a filter plate and a filter frame through a feed inlet, filter cloth is arranged between the filter plate and the filter frame, then filter pressing is carried out through a pressurizing mechanism, and water filtered by pressing passes through the filter cloth and flows to corner channels of the filter plate and the filter frame along a groove of the filter plate, and finally is discharged in a centralized manner.
However, plate-and-frame filter presses in the current market all adopt hydraulic cylinders to compress the filter plates and the filter frames, have no mechanical locking function, and always need to keep the pressure on the filter plates and the filter frames in the subsequent filter pressing process to resist the filter pressing pressure, so that all the filter plates and the filter frames are tightly sealed and cannot leak. However, the pressure sealing method mainly has the following disadvantages: 1) the hydraulic cylinder is required to always maintain certain pressure in the whole working process of the plate-and-frame filter press, and the energy consumption is high; 2) if the pressure of the hydraulic cylinder is unstable, the sealing between the filter plate and the filter frame is not tight, and leakage is caused.
Meanwhile, plate-and-frame filter presses in the current market generally adopt automatic operation in the filter plate assembling or separating stage, namely, automatically assemble and separate one by using a plate pulling device. When one filter plate is separated, the filter plate needs to be vibrated to separate mud cakes from the filter plate, and the filter cloth needs to be washed by a high-pressure water gun after the mud cakes on the filter plate completely fall off, and then the next filter plate can be separated, so that the sludge dewatering efficiency is seriously influenced; meanwhile, the existing plate and frame filter has insufficient mud cake dehydration rate and water content of 60-70 percent, which is not beneficial to the realization of subsequent resource utilization.
