Description

Filter press for wastewater treatment Technical Field The utility model relates to the technical field of wastewater treatment, in particular to a wastewater treatment filter press. Background The filter press is a mechanical device which utilizes a special filter medium to apply a certain pressure to an object to extract solids in the mixed liquid and realize the solid-liquid separation effect. The filter plate is a main filter element of the filter press, a filter chamber is formed by discharging a plurality of filter plates on a main beam of the filter press, two sides of the filter plate are covered by filter cloth, the filter chamber is sealed by the compaction pressure, the material is injected into the filter chamber by the pressure of a feed pump, particles in the material are trapped by the filter cloth in the filter chamber to form a filter cake, the filtrate is discharged through a filter plate slurry inlet, and the filter cake is removed by pulling the filter plate through a plate pulling device arranged on the filter press, so that the purpose of solid-liquid separation is achieved. At present, as the compacting plates and the filter cloth are in a parallel state before, and the compacting plates and the filter cloth are vertically arranged in the machine body, the filter plate is easy to deform under relatively high pressure after long-time extrusion, the gap between the filter plates is reduced, the material containing amount is small, and the produced filter cake is small in size and affects the production efficiency. For the problems in the related art, no effective solution has been proposed at present. Disclosure of utility model Aiming at the problems in the related art, the utility model aims to provide a wastewater treatment filter press which is used for overcoming the technical problems existing in the prior related art. The technical scheme of the utility model is realized as follows: The wastewater treatment filter press comprises a frame, wherein main beams which are symmetrically arranged are arranged on two sides of the frame, a thrust plate is arranged on one side of the frame, a plurality of groups of filter plates and compression plates are arranged between the main beams, a plurality of groups of filter plates are positioned between the thrust plate and the compression plates, and a filter chamber is formed between adjacent filter plates, wherein the filter plates are arranged on the side of the frame; The filter plate is characterized in that one side of the compacting plate is connected with an oil cylinder output end arranged on one side of the frame, a feed inlet is arranged on one side of the thrust plate, a through hole and a filtering protrusion are arranged in the filtering chamber and positioned in the filtering chamber, and a plurality of diversion trenches distributed along the annular array of the through hole are arranged on the surface of the filter plate. Further, the feed inlet is connected with a pulp inlet pump. Furthermore, limit feet which are symmetrically arranged are respectively arranged on two sides of the filter plate, and the limit feet are movably connected with the main beam. Further, filter cloth is arranged between the filter plates. Further, a pore canal for discharging filtrate is arranged on the surface of the filter plate, and a liquid outlet valve is arranged in the pore canal. Further, the filtering protrusions are at least four groups, the four groups of filtering protrusions are distributed along the through holes in an annular array, the diameter of each filtering protrusion is 5-6 cm, and the height of each filtering protrusion is 2-3 cm.
