Filter press for sewage treatment

Abstract

The invention discloses a filter press for sewage treatment. The filter press comprises a pedestal, a rack mounted on the pedestal, a filter plate arranged on the rack, a fixed tail plate and a pressing plate. Pushing plates for removing filter cake residue from the filter plate is arranged on the rack, a driving device for driving the pushing plate is fixedly connected to the pushing plates, andthe driving device is fixedly connected to the rack. According to the filter press for sewage treatment disclosed by the invention, the pushing plates are arranged on the rack and can clear residual filter cake residue on the filter plate in time, thus effectively improving the efficiency of separating the filter cake from the filter plate, enabling stable movement of the filter plate on the rack,and preventing residual filter cake residue on the filter plate from causing centre-of-gravity shift of the filter plate. At the same time, the pushing plates involved in the scheme can assist in pushing the filter plate to move stably on the rack, so that the filter plate can move more stably on the rack, and at the same time the service life of the filter plate is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of filter presses, in particular to a filter press used for sewage treatment. Background technique [0002] The filter press uses a special filter medium to exert a certain pressure on the object, which is a mechanical device that makes the liquid dialysis out. It is a commonly used solid-liquid separation device. It was used in chemical production in the early 18th century and is still used today. Widely used in chemical, pharmaceutical, metallurgy, dye, food, brewing, ceramics and environmental protection industries. [0003] At present, when the filter cake in the existing filter press is taken out, the filter plate needs to be separated by the plate pulling mechanism on the filter press, and the filter cake will automatically fall under the action of its own gravity, but the filter plate often sticks The filter plate cannot fully fall, so there is a process in which the filter plate is walking on the tr...

AI Technical Summary

Problems solved by technology

[0003] At present, when the filter cake in the existing filter press is taken out, the filter plate needs to be separated by the plate pulling mechanism on the filter press, and the filter cake will automatically fall under the action of its own gravity, but the filter plate often sticks The filter plate cannot fully fall, so there is a process in which the filter plate is walking on the track. Due to the filter cake residues adhering to different positions on the filter plate, the center of gravity of the filter plate is shifted, so that the filter plate is walking on the track. There is a phenomenon of tilting, and the filter plate is unstable when moving. On the one hand, it will damage the service life of the filter plate, and at the same time cause the plate pulling mechanism to be worn. Therefore, we propose a filter press for sewage treatment.
