A screen mechanism for sewage treatment

Abstract

The utility model relates to sewage treatment field, concretely relates to a grating mechanism for sewage treatment, including grating drive assembly, grating drive assembly is installed in the inside of sewage tank, the utility model discloses a grating mechanism for sewage treatment is through the setting of grating drive assembly, grating collection tank, servo motor, first synchronous wheel, reciprocating lever, mobile seat, brush head, synchronous belt, second synchronous wheel, connecting rod and softness scraper, when grating drive assembly will impurity pull up, through opening servo motor switch, drive first synchronous wheel and the rotation of reciprocating lever of outside, utilize reciprocating lever rotation to drive the mobile seat and the front brush head of outside in the grating drive assembly top end back and forth cleaning, and first synchronous wheel drives the synchronous belt of outside and the second synchronous wheel of other side when rotating, utilize second synchronous wheel rotation to drive the connecting rod of one side and the softness scraper of outside stick in the position of grating collection tank inside inclined plate cleaning.
