Filtering containing tank

Abstract

The invention relates to the technical field of filtering equipment, and discloses a filtering containing tank which comprises a tank body and a tank cover, a feeding pipe and a discharging pipe are arranged on the tank body, a filtering bag and a supporting filtering net plate which is arranged at the bottom of the filtering bag and used for supporting the filtering bag are installed in the tank body, and a positioning assembly is further arranged in the tank body and used for fixing a bag opening of the filtering bag. A traditional thought that the filter bag and the filter cylinder are arranged in a matched mode for filtering is abandoned, the bag opening of the filter bag is fixed through the positioning assembly, meanwhile, the bottom of the filter bag is supported through the supporting filter screen plate, in addition, the exhaust pipe arranged on the tank body can exhaust gas brought in when liquid is injected into the feeding pipe in time, the gas brought in when liquid is injected can increase the pressure intensity in the tank body, and the auxiliary filtrate is efficiently and continuously filtered; the positioning assembly adopts the design that the pressing ring and the supporting ring are matched in an embedded and inserted mode, on one hand, the filter bag can be stably positioned, and on the other hand, the filter bag can be rapidly disassembled and assembled.

Description

technical field [0001] The present invention relates to the technical field of filtering equipment, in particular to a filtering tank. Background technique [0002] The filter tank is a device that separates the filtrate and the filter residue. The design of the traditional filter tank is too complicated. For example, the patent with the publication number CN206676066U discloses a solid-liquid separation bag filter, and the outer periphery of the filter bag is also provided with a filter The cartridge wraps the filter bag. Although the setting of the filter cartridge can provide a good positioning support for the filter bag, it also brings certain obstacles to the flow of the fluid during filtration, reduces the filtration efficiency, and the filtration process cannot be carried out quickly. . And in this patent, the filter bag is fixed by fixing the filter cartridge, the filter bag cannot be positioned independently, and the filter bag may become loose during the filtering...

[0002] The filter tank is a device that separates the filtrate and the filter residue. The design of the traditional filter tank is too complicated. For example, the patent with the publication number CN206676066U discloses a solid-liquid separation bag filter, and the outer periphery of the filter bag is also provided with a filter The cartridge wraps the filter bag. Although the setting of the filter cartridge can provide a good positioning support for the filter bag, it also brings certain obstacles to the flow of the fluid during filtration, reduces the filtration efficiency, and the filtration process cannot be carried out quickly.

Moreover, in this patent, the filter bag is fixed by fixing the filter cartridge, the filter bag cannot be positioned independently, and the filter bag may become loose during the filtration process, which cannot ensure that the filtrate is completely filtered
