Abstract

The invention relates to a sewage filter screen capable of being replaced rapidly. The sewage filter screen effectively solves the problems that a common filter screen is difficult to replace, the sealing performance is poor when the filter screen is rapid to replace, or a sealing part is easy to damage. According to the technical scheme of the sewage filter screen, the filter screen is replaced in a drawing and pulling mode, when the filter screen which is replaced is completely pulled away from a sewage treatment pipeline, a clean filter screen is arranged in place, so that the operation ofreplacing the filter screen is convenient and rapid, manpower and time are saved, the filter screen and a flange are sealed through inflatable sealing rings, so that the good sealing effect can be achieved, the inflatable sealing rings can be deflated first when the filter screen is replaced, the deflated inflatable sealing rings can not generate resistance when the filter screen is pulled out, inaddition, abrasion to the inflatable sealing rings is avoided when the filter screen is pulled out, so that the inflatable sealing rings can be repeatedly used, and resources are saved.

Description

Technical field [0001] The invention relates to the field of sewage treatment, in particular to a quickly replaceable sewage filter. Background technique [0002] In sewage treatment, the large impurities or floating objects in the sewage are first filtered. Generally, a filter is used to filter the sewage. When the filter is blocked, it will block the flow of water and reduce the efficiency of sewage treatment. When the filter is damaged Sometimes, large impurities or floating objects will pass through the filter, reducing the quality of filtration; the process of replacing the ordinary filter is complicated and requires multiple people to work together, wasting manpower and time, and the rapid replacement of the filter will cause sewage leakage due to poor sealing performance. Or the sealing effect is good but the resistance generated by the sealing element is relatively large when the filter is replaced, and the sealing element will be damaged when the filter is quickly replac...
