Description

Technical Field

[0001] This utility model relates to the field of chemical and pharmaceutical technology, and more specifically, to a liquid filtration device that can clean filter residue in a timely manner. Background Technology

[0002] In the chemical and pharmaceutical industry, materials inevitably contain impurities. In order to improve production efficiency, filtration devices must be used to purify the materials.

[0003] The existing patent publication number, CN103619759A, discloses a permeation filtration device, which only guarantees the filtration effect on the water to be filtered, but does not consider how to easily clean the filtered impurities. Directly replacing the filter element is costly and the operation is relatively complicated; moreover, as the thickness of the filter cake increases, the filtration efficiency tends to decrease. In summary, the existing technology suffers from high production costs and unstable filtration rates. Utility Model Content

[0004] In view of this, in order to solve the problem of the inability to clean filter residue, this utility model proposes a liquid filtration device that can clean filter residue in a timely manner, including a filter tank body 1, an inlet 4 and an outlet 11 respectively disposed on the upper part of the filter tank body 1. The filter tank body 1 is a hollow cavity, and the inner wall of the filter tank body 1 is provided with a quick assembly device 12 that can be longitudinally engaged with a filter element 13. The filter element 13 is installed on the quick assembly device 12, and the filter element 13 divides the hollow cavity of the filter tank body 1 into an inlet chamber and an outlet chamber. In this invention, the feeding chamber is connected to the feeding port 4, and the discharging chamber is connected to the discharging port 11. The feeding chamber has a cleaning port 6 on the side near the bottom of the filter tank body 1. The material enters the feeding chamber from the feeding port 4, is filtered by the filter element 13, enters the discharging chamber, and is discharged from the discharging port 11. This invention can effectively filter impurities in liquid materials. At the same time, since the filter element 13 is vertically arranged, the impurities will be deposited at the bottom of the feeding chamber. The filtered impurities can be cleaned in time through the cleaning port 6, thereby improving production efficiency.
