The filter chamber comprises two rectangular frames and four upright posts, and one upright post is arranged at each of four corners of each of the two rectangular frames to form a three-dimensional frame; a filter plate is arranged between every two adjacent stand columns on the inner side of the three-dimensional frame; a plurality of filter holes are formed in the filter plate; a filter chamber is defined by the filter plates; reinforcing rib plates for supporting the filter plate are arranged on the filter plate between every two adjacent stand columns on the outer side of the three-dimensional frame, wherein one side face of the filter chamber is of an open-close structure to form a filter chamber door; one side of the filter chamber door is rotationally connected with the stand columns connected with the filter chamber door, and the other side of the filter chamber door is matched with the adjacent stand columns to be closed. The filter chamber is opened / closed by arranging the filter chamber door, so that mud cakes obtained after filter pressing in the filter chamber are rapidly poured out, and the labor cost is reduced. The filter medium is directly mounted in the filter chamber, so that the time required for replacing the filter medium is shortened, and the working efficiency of the filter press is improved.

The invention discloses a filter plate for a plate filter press. The filter plate comprises a filter plate body of which four sides protrudes outwards to form a frame. Positioning holes are formed at four corners of the frame. An inclined plate body is arranged in the frame. The distance between the upper end of the plate body and a plane of the frame is shorter than the distance between the lower end of the plate body and the plane of the frame. The plate body and the frame are integrally molded to form the filter plate body. A feeding hole is formed at the center of the plate body. A plurality of filtering holes are uniformly formed around the feeding hole. Filtering holes are also formed in the lowest side of the plate body and provided with a filter cloth. An elastic frame matched with the plate body is arranged at one side of the filter plate body.

This application relates to the field of sewage discharge equipment, in particular to a filter press cleaning device, which includes a base and a mounting seat connected to the base, and a lifting assembly for lifting the mounting seat is provided between the base and the mounting seat. An installation chamber is provided, and a flushing assembly is provided in the installation chamber, a beating assembly for beating the filter plate is provided on the bottom surface of the installation seat, and a driving assembly for driving the base to move is provided on the base. The flushing assembly includes a delivery pipe arranged in the installation cavity, and a high-pressure nozzle connected to the delivery pipe. There are several high-pressure nozzles arranged at intervals along the length of the delivery pipe. A water pump is fixedly connected to the mounting base, and the delivery pipe communicates with the water pump. The present application has the effect of improving the cleaning effect of the filter plate, and further improving the filtering effect of the filter press.

The invention relates to a three-chamber structure small-test filter-press analog device. The three-chamber structure small-test filter-press analog device comprises a sealed housing with two detachable ends, wherein the housing is divided into a working chamber, a middle chamber and a pressurizing chamber which are straightly arranged in sequence by a first piston and a second piston; filter cloth is arranged on the side walls of two ends of the working chamber respectively; the two ends of the working chamber are communicated with an outer drainage pipe and a drainage flow passage on the first piston respectively; the first piston and the second piston are connected through a first rigid inner drainage pipe; the first inner drainage pipe is communicated with drainage flow passages on the first piston and the second piston respectively; a second inner drainage pipe stretches into the pressurizing chamber in a sealing manner to be communicated with the drainage flow passage on the second piston; and high-pressure dielectric joints are arranged on the middle chamber and the pressurizing chamber respectively. The device adopts a three-chamber structure, the pistons after filter pressing is completed can be quickly reset, and the device is convenient in operation and high in efficiency.

The invention discloses a traditional Chinese medicinal residue-medicinal liquid separator, and belongs to the field of traditional Chinese medicine production equipment, wherein the separator includes a press filter cartridge, a centrifugal separation cartridge and a liquid collecting cartridge; a press hammer and a driving mechanism are arranged directly above the pressure filter cartridge; a rotating motor is connected at the bottom of the centrifugal separation cartridge; the bottom of the liquid collecting cartridge is connected with a liquid storage tank through an infusion tube, and a liquid taking port is arranged on the liquid storage tank. The press filter cartridge comprises a first circular side wall, and a support bottom plate and a covering top plate which are slidingly connected on the first circular side wall; a magnetic attraction effect exists between the press hammer and the covering top plate; the press hammer is connected with a movable rod of a telescopic sleeve rod structure; a buffer spring is fixed on a flange edge of the support bottom plate. The centrifugal separation cartridge includes a second circular side wall, a first top panel and a first bottom panel. The inner side wall of the second circular side wall is provided with a corrugated convex rib, and the centrifugal separation cartridge is internally provided with a cleaning brush fixed on the liquid collecting cartridge. A medicinal liquid can be completely and adequately extracted, the separation effect between the medicinal liquid and the medicinal residue is good, wasting of the medicinalliquid is avoided, the separation effect is good and the separation efficiency is high.

The invention discloses a filter press with a movable check valve and a use method of the filter press. The equipment comprises a cylinder body, a compaction chamber, a reciprocating propelling device and a valve element driver, an on-off valve is mounted in the cylinder body in a sliding manner and comprises a valve body capable of moving back and forth along the inner wall of the cylinder body and a valve core for opening and closing an internal flow channel of the valve body; a detachable filter plate is mounted at the front end of the valve body; the reciprocating propelling device drives the valve body to move back and forth along the inner wall of the cylinder body, and the valve element driver drives the valve element to open or close an internal flow channel of the valve body; the front end of the compaction chamber is provided with an elastic damper capable of blocking the front port of the compaction chamber. According to the invention, the configuration of a high-power feeding pump is omitted, and the investment and operation and maintenance costs are effectively reduced. According to the equipment, the filter pressing efficiency and effect are greatly improved, the filter plate is reversely washed, blockage is automatically cleaned, and the service life of the filter plate is prolonged; therefore, the solid-to-liquid ratio of the filter cake is guaranteed, retreatment of the filter cake is avoided, and the transportation cost of the filter cake is reduced.

The invention belongs to the technical field of environmental engineering, and particularly relates to a method for deep dehydration of cyanobacteria. The method comprises the steps: conditioning cyanobacteria produced by an algae-water separation station, performing filter pressing so as to obtain cyanobacteria algae gel with a water content of 60% or below, and treating filtered water through analkali liquid, an air floating pool, an AO biological pool and a sedimentation tank so as to meet the urban sewage discharge standard, wherein the alkali liquid is used for adjusting the pH value ofthe filtered water to neutrality or weak alkalinity, in the air floating pool, a coagulant and coagulant aids are utilized to perform a coagulation reaction with the filtered water, and after floc isformed, solid-liquid separation is conducted through an air floatation effect. The problem of high water content of the cyanobacteria algae gel is solved, and the water content of the cyanobacteria algae gel can be reduced effectively after conditioning and pressure filtration are performed, so that reduction of the cyanobacteria is achieved after salvage is performed, and subsequent treatment isfacilitated.
