A plate filter press

Abstract

The invention relates to the technical field of chemical industry, and discloses a plate filter press, comprising a body, an oil pump, a filter plate, an oil pump installed on the body, and a filter plate installed on the end shaft of the oil pump and axially moving along the oil pump. Positioning shafts are installed on both sides of the filter plate, a positioning rod is rotatably installed on the positioning shaft, a positioning block is installed at the end of the positioning rod, and a positioning seat is installed at both ends of the positioning block. During the working process of the plate pulling machine, only the first filter plate can be pulled to open the subsequent filter plates in a step-by-step manner, so that the entire filter plate is opened and the filter cake is in a linkage state, thus saving the time of opening the filter plate and removing the filter cake. The working efficiency of the equipment is greatly increased, and the angle of the positioning rod changes continuously during the opening process of the filter plate, thereby driving the pressure plate to slide down, giving a downward force to the filter cake, coupled with the effect of gravity, Therefore, the filter cake adsorbed on the filter plate is removed, and the problem that the filter cake is too viscous and needs to be cleaned manually is solved.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a plate filter press. Background technique [0002] Plate filter press is plate and frame filter press, plate and frame filter press, plate filter press has large filtration area, large flow rate and wide application range, so it is widely used in pharmaceutical, chemical, food and other industries. [0003] In order to separate the sludge in the sewage or the sludge in the oil pollution from the liquid, a filter press is often used to accumulate the sludge in the filter plate to form a filter cake, thereby separating and filtering the liquid. The work of the existing filter press The principle is to start the oil pump, so that the piston rod drives the filter plate closer to the inside and gradually compress it, and then start the feed pump to transport the feed liquid into the filter plate. When the feed liquid is filtering, the liquid flows out from the filter plate,...

AI Technical Summary

Problems solved by technology

[0004] In view of the shortcomings of the above-mentioned background technology, the present invention provides a plate filter press, which has the advantages of quick removal, no adsorption, and no clogging, and solves the problem that the adsorption on the filter plate cannot fall off. When the plate pulling machine is in operation, the dirt The mud is affected by gravity, and the lower part falls off, while the upper part cannot fall due to the influence of viscosity, or the lower part is affected by viscosity, causing the entire filter cake to be adsorbed on the filter plate, which needs to be removed manually, and the plate pulling machine During the operation, the filter plates can only be opened one by one, resulting in a long time for unloading the filter cake and increasing the running time. At the same time, the sludge adsorbed on the filter plate will also block the pores on the filter plate, resulting in After using for a certain period of time, the filtering effect gradually decreases, resulting in a significant reduction in the filtering effect of sludge, which in turn affects the working efficiency of the entire equipment.
