Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sewage filtration, particularly to a plate-and-frame water channel for a plate-and-frame filter press. BACKGROUND

[0002] The plate-and-frame filter press is a device for separating solid and liquid in sewage. When filtering sewage, filter cloth is first installed on a plurality of plate-and-frame filter plates, and then the plurality of plate-and-frame filter plates are pressed together by a pressing device. Subsequently, the sewage is delivered to the plurality of plate-and-frame filter plates that are pressed together by a delivery mechanism. When the sewage is filtered on the plate-and-frame filter plates, it is filtered by the filter cloth on the plate-and-frame filter plates. The clean water passes through the filter cloth and is discharged to the outside through the water channel on the filter plate. However, the following problems exist in the process of use. Once the filter cloth is damaged, the sewage containing solid impurities is likely to enter the water channel of the plate-and-frame filter plate, which not only easily causes sewage overflow, but also easily causes the water channel to be blocked by the solid impurities entering the water channel of the plate-and-frame filter plate, which is inconvenient to use and has poor reliability. SUMMARY

[0003] To solve the above technical problems, the utility model provides a plate-and-frame water channel for a plate-and-frame filter press, which is characterized in that a filtering mechanism is arranged on the drainage mechanism of the plate-and-frame filter plate. The water filtered by the filter cloth is first filtered by the filtering mechanism when entering the drainage mechanism, so that the solid impurities in the sewage do not enter the drainage mechanism of the plate-and-frame filter plate and cause blockage when the filter cloth is damaged, which is convenient to use and improves the reliability and safety.

[0004] The plate-and-frame water channel for the plate-and-frame filter press of the utility model comprises a plate-and-frame filter plate. The upper and lower parts of the plate-and-frame filter plate are both provided with a drainage mechanism, which has a drainage function. The input ends of the two groups of drainage mechanisms are both provided with a filtering mechanism, which has a filtering function. When the plate-and-frame filter plate is used on the plate-and-frame filter press, the water filtered by the filter cloth is discharged through the drainage mechanism on the plate-and-frame filter plate. Before entering the drainage mechanism, the water is filtered again by the filtering mechanism and then discharged into the drainage mechanism of the plate-and-frame filter plate. Since the water filtered by the filter cloth is first filtered by the filtering mechanism when entering the drainage mechanism, the solid impurities in the sewage do not enter the drainage mechanism of the plate-and-frame filter plate and cause blockage when the filter cloth is damaged, which is convenient to use and improves the reliability and safety.

[0006] Preferably, the filtering mechanism comprises a plurality of filter pieces, the plurality of filter pieces are respectively installed at the input ends of the plurality of water inlet holes, and the plurality of filter pieces are respectively provided with a plurality of filter holes in communication with front and back; when the water filtered by the filter cloth is discharged on the plate-and-frame filter plate, the water passes through the filter holes on the filter pieces and then enters the water inlet holes, and then is discharged to the outside through the conveying grooves, the discharge groove and the drainage hole; because the water is first filtered by the filter holes on the filter pieces before entering the water inlet holes, when the filter cloth is damaged, the large-particle impurities in the sewage are prevented from entering the water inlet holes to cause blockage, thereby improving reliability and practicability.

[0007] Preferably, the filter piece is provided with external threads, the water inlet hole is provided with internal threads, and the filter piece is screwed with the internal threads on the water inlet hole through the external threads; through the above arrangement, the filter piece and the water inlet hole are detachably connected, thereby facilitating replacement and maintenance of the filter piece.
