Comet filler filtering equipment

Abstract

The invention discloses comet filler filtering equipment. A filter chamber is arranged in a filter cartridge, the filter chamber has a vertically arranged columnar structure, an upper pressure plate and a lower pressure plate are horizontally arranged in the filter cavity, a first filter hole is formed in the upper pressure plate and a second filter hole is formed in the lower pressure plate, a driving mechanism is connected to the upper pressure plate and the lower pressure plate for driving the upper pressure plate and the lower pressure plate to move relatively, and filter units is located between the upper pressure plate and the lower pressure plate and two ends of the filter unit are separately connected to the upper pressure plate and the lower pressure plate. According to the comet filler filtering equipment of an optimization design, the upper pressure plate and the lower pressure plate press the filter units together during filtration to form a filter structure. A plurality of comet type filter bodies are connected together through a connecting line to prevent movement of the comet type filter bodies between the upper pressure plate and the lower pressure plate, filter materials in filter positions are uniform. In addition, during back washing, the distance from the upper pressure plate to the lower pressure plate is increased to provide a flushing space for the filter materials, so that the filter effect is improved greatly and the back washing is facilitated.

Description

technical field [0001] The invention relates to the technical field of filtration, in particular to a comet packing filtration device. Background technique [0002] With the development and popularization of comet-type fiber filter materials, filter tanks using these fiber filter materials are becoming more and more popular with environmentalists. Therefore, many fiber filter tanks of various colors appear in the society. Conventional filters using comet-type fiber filter material can backwash the filter material through the bottom flushing port. During the backwashing process, the high-pressure gas divides the air-water distribution channel into the upper air cavity and the lower water cavity. Since the separation boundary is the liquid surface , there are fluctuations, it is easy to make the air distribution uneven and affect the backwashing effect. Contents of the invention [0003] In order to solve the technical problems existing in the background technology, the pre...
