[0002] As we all know, the box-type sewage filter is an auxiliary device used for preliminary filtration of sewage in the sewage treatment process to make it better for subsequent treatment. It has been widely used in the field of sewage filtration; the existing The box-type sewage filter includes a bottom plate, a working box and a filter plate. The working box is installed on the top of the bottom plate. The material plate, the lower part of the front side of the work box is sealed and connected with a discharge pump, and a discharge valve is set at the discharge pump. The top of the work box is connected with a maintenance port, and a maintenance plate is set at the maintenance port. The filter plate is installed Inside the working box; when using the existing box-type sewage filter, open the feeding plate and the discharge valve, and introduce the sewage into the working box through the feeding port. The unloading pump is exported for subsequent processing. The unloading pump is a common electrical device in the market. When buying it back for use, it only needs to be electrically connected according to the instruction manual purchased together, so it will not be repeated here; now In the use of some box-type sewage filters, it was found that when the filter plate was clogged, it could not be conveniently dredged in time, resulting in poor reliability in use; and the unloading pump could not be easily unloaded when unloading, resulting in poor practicability; and It is not convenient to observe inside the working box, which makes it more inconvenient to use
