Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a filtering auxiliary device which is convenient for replacing a filter element. Background Art

[0002] Most of the earliest filtration was gravity filtration. Later, pressure filtration was used to increase the filtration speed, and then vacuum filtration appeared. The rotary drum vacuum filter invented in the early 20th century realized the continuous filtration operation. Since then, various types of continuous filters have appeared one after another. Intermittently operated filters (such as plate and frame filter presses, etc.) have been developed because they can realize automated operation, and the filtration area is getting larger and larger. At present, PVDF is often used in filters. The ultrafiltration membrane PVDF hollow fiber membrane has the characteristics of high porosity, high flux, stable properties, anti-aging, long life, excellent surface properties, anti-pollution, easy cleaning, etc., and is widely used in various fields, especially in water purification and sewage treatment.

[0003] After the filter has been working for a long time, the filter element is prone to accumulate certain debris and cause the filter to be blocked. If it is not cleaned, long-term use will affect the filtering effect. In some common filters, the filter element is often fixed on the filter and is not easy to disassemble, which makes it more troublesome to clean the filter element.

[0004] For this reason, we propose a filtering auxiliary device which is convenient for replacing the filter element. Utility Model Content

[0015] 1. When the filter element body needs to be cleaned, the staff first holds the handle with both hands, and then pulls up the top cover, and then lifts up the fixing plate at the top to take out the filter element body from the inside of the filter barrel. When the filter element body is cleaned and installed, first align the round groove with the round rod, then insert the filter element body into the inside of the filter barrel, then rotate the round rod against the slot to install the top cover, and then press the top cover down to make the sealing strip enter the inside of the filter barrel to close the filter barrel and preliminarily fix the position of the filter element body.

[0016] By setting up the installation component, the filter element body can be easily disassembled and the overall sealing effect of the filter barrel can be better.
