Abstract

The invention discloses a kind of sewage treatment equipment which is convenient to replace the filter screen. The sewage treatment equipment comprises; The water pipe is fixedly connected to the top of the filter box, and the multi-effect filter layer is fixedly installed inside the tank body; the garbage filter mechanism, the garbage filter mechanism includes a guide wheel, a filter screen and a limit strip, and the two ends of the guide wheels rotate Installed on the side wall of the filter box, two limit bars are symmetrically sleeved between the two guide wheels; the replacement assembly includes a connecting bar, a block and a moving rod, and the two ends of the connecting bar are fixedly connected Between the two limiting bars, a plurality of moving bars are equidistantly threaded on the upper end of the connecting bar, and the resisting block is fixedly connected to the bottom of the moving bars. The speed of filtering and cleaning is improved, and the service life of the device is extended at the same time. At the same time, the replacement method is simple and quick, and the replacement rate of the filter screen is improved.

Description

technical field [0001] The invention relates to the technical field of environmental treatment, in particular to a sewage treatment device which is convenient for replacing filter nets.

Problems solved by technology

[0003] However, most of the current filter screens are fixed. When used for a long time, the filter holes on the filter screen will be blocked, so that the sewage cannot be filtered normally. If the filter screen is not replaced in time, the sewage treatment equipment will be blocked and the filtering effect will be reduced.
