Method and device for supporting and fixing filter element of precision filter by using upper seal head

Abstract

The invention relates to a method and a device for supporting and fixing a filter element of a precision filter by using an upper seal head. The method comprises the steps of firstly preparing the upper seal head of the precision filter, opening an operation hole for manual assembly by an operator on the top part of the upper seal head, wherein the upper seal head and a cylinder body of the precision filter have a seal head butt joint part and a cylinder body butt joint part; then connecting filter element press head supports which are at least three in a casing of the upper seal head; and subsequently combining the upper seal head which is connected with the filter element press head supports with the cylinder body of the precision filter together. The method changes the filter element supporting and fixing way of the prior art which has been used for decades, the processing cost is saved by more than 30 percent in comparison with the prior art, and metal materials are saved by more than 50 percent in comparison with the way of a flange disc; furthermore, the device has simple and smooth shape which is conductive to assembly; and the installation process of the filter element can be observed and grasped, thereby ensuring the overall quality of the precision filter.

Description

technical field [0001] The invention relates to a structure of a filter and a water purifier, in particular to a supporting and fixing method and device structure of a filter element of a precision filter. Background technique [0002] The supporting and fixing method of the precision filter element in the prior art is as follows: figure 1 As shown, a clean water space 22 is isolated from the lower part of the cylinder body 20 by the lower support plate 30, and the cylinder bottom 21 is used to fix the whole precision filter. [0003] The lower support plate 30 is provided with the lower fixing hole 31 of the filter element, which is both a hole for fixing the filter element 50 and a water purification hole. The water in the space above the lower support plate 30 is filtered by the filter element 50 and then flows into The clean water space 22 is output through the clean water joint 25 at last. [0004] In the prior art, the upper part of the filter element 50 is as figur...

AI Technical Summary

Problems solved by technology

[0010] To sum up, the cost of material preparation and processing for the fastening method of the flange and the pull button is high, accounting for about 30% of the entire cost, and metal materials are wasted, and the equipment is cumbersome

Fixing with clamps does not guarantee the sealing effect

[0011] The above existing technologies have been used for decades and have not changed
