Filtering device for sewage treatment in rural environment

Abstract

The invention discloses a filtering device for sewage treatment in a rural environment, which comprises: mounting racks symmetrically erected on the left and right sides of a sewage flow channel; the fixed shaft seats are arranged corresponding to the mounting racks, and the fixed shaft seats are fixed on the upper end surfaces of the mounting racks; the central shaft is transversely arranged between the fixed shaft seats in a penetrating manner in a relatively rotating manner; the multiple filter screen plates are arranged in a circumferential array mode, and all the filter screen plates are installed on the center shaft; the flow limiting frame body is embedded and fixed in the sewage flow channel, and the flow limiting frame body can be matched and matched with the filter screen plate; the external discharging and conveying frame is arranged on one side of one mounting frame, and the external discharging and conveying frame can push out and discharge the garbage sundries on the filter screen plate in time; and the plurality of airflow pollution discharge assemblies are arranged in an arrayed manner, and each airflow pollution discharge assembly is vertically embedded and mounted on each filter screen plate.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment equipment, in particular to a filter device for sewage treatment in rural environment. Background technique [0002] In the process of rural environmental governance, rural sewage treatment is one of the main tasks. Rural domestic sewage includes kitchen and bathroom sewage, bathing sewage, and livestock raising sewage. In the existing rural sewage treatment, most of the sewage is transported to the sewage treatment plant through buried pipelines. After various processes, the sewage gradually reaches the discharge standard. At present, in the primary filtration of sewage, since the sewage is mixed with floating garbage, it is very easy to cause accumulation and blockage in the filter device during filtration. At this time, it is necessary to manually fish the floating garbage, which is time-consuming and labor-intensive; [0003] Therefore, those skilled in the art provide a filter devi...
