Repair-free square filter cloth filter equipment

Abstract

The invention discloses repair-free square filter cloth filter equipment. A cleaning mechanism can travel on a rail on a sewage treatment water tank and is connected with a sewage absorption and drainage device; a sewage absorption cleaning pipe on the cleaning mechanism is in contact with filter cloth on a filter; when the cleaning mechanism travels on a guide rail, the sewage absorption cleaning pipe can absorb spots retained on the filter cloth so as to avoid influence caused by blocking of the filter cloth on the filter on the sewage filtration treatment, so that the filter cloth can be always kept clean, the usability of the filter is improved, and the sewage treatment cost is reduced; moreover, a movable plate component for automatically closing a water inlet of a water collection tank after the filter is separated from the water collection tank is arranged on the inner side of the water inlet of the water collection tank; when the filter is replaced, a phenomenon that filtered sewage is re-polluted because sewage directly enters the water collection tank is effectively avoided, and a maintainer can randomly replace the filter conveniently in a sewage treatment process; the influence on the sewage treatment is avoided; the maintenance efficiency of equipment is improved; the working amount of a worker and the sewage treatment cost are reduced.

Description

【Technical field】 [0001] The invention relates to sewage treatment filtering equipment. 【Background technique】 [0002] In the sewage treatment, the sewage first enters the sewage treatment tank through the pipeline. In order to improve the filtration speed of the sewage, there are multiple sumps at the bottom of the sewage treatment tank. Shuikou. After a long time of use, the filter cloth on the water inlet of the filter will be blocked by the stains in the sewage, and after a long time, a lot of sludge will be deposited in the sewage treatment tank, which will reduce the filter's ability to filter sewage, so it needs to be replaced frequently Filters, for this reason, bring a lot of workload to the staff, increase the cost of sewage treatment, and also affect the efficiency of sewage treatment. [0003] In addition, after the filter cloth on the filter is blocked by the stains in the sewage, the filter needs to be replaced in time. When replacing the filter, it is neces...

Problems solved by technology

With this kind of open-opening structure of the sump, the filter cannot be replaced when the sewage is filtered normally, otherwise the sewage will directly enter the sump without being filtered by the filter, and the filtered sewage will be polluted again; if the filter is replaced , close the water inlet valve and stop filtering sewage, which will reduce the efficiency of sewage treatment and affect production
