Large particle cleaning device for sewage discharge pretreatment of ecological lakes

Abstract

The invention discloses a large particle cleaning device for sewage discharge pretreatment of ecological lakes. The device comprises a protective housing; a protective cover plate is fixed at the leftend of the protective shell; a flow guiding plate is fixed on the front side of the interior of the protective shell; clamping structures are fixed to the left end and the right end in the protectiveshell correspondingly; filter screens are fixed to the ends, close to each other, of the two clamping structures; first rotating rods are movably connected to the left end and the right end of the interior of the protective shell through bearings; rotating fans are fixed to the left side and the right side of the outer surface of each first rotating rod; first transmission mechanisms are arrangedin front of the two clamping structures respectively; and second transmission mechanisms are arranged below the two first transmission mechanisms respectively. According to the large particle cleaning device of the invention, when sewage is discharged, large particles adhered to the surface of the filter screens can be cleaned in time; and the blockage of the filter screens caused by particle accumulation is avoided, and therefore, the condition that the sewage discharge speed is slowed down is avoided, and the condition that water discharge time is prolonged is avoided.

Description

technical field [0001] The invention relates to the technical field of sewage discharge devices, in particular to a device for cleaning large particles for pretreatment of sewage discharge in ecological lakes. Background technique [0002] Every time one end of the lake passes due to the influence of people, sewage will be produced. When the sewage is discharged, the large particles in the sewage will generally be pretreated, and the sewage will be discharged after a certain purification. For example, the Chinese invention patent authorized by the announcement number CN108341445A A sewage treatment device for discharging and separating sewage particles, by setting a pipe shell, a solid pipe cover, a plate shell, a sewage pipe and a water outlet, the right end of the pipe shell is provided with a solid pipe cover, and a sewage discharge pipe is built in the solid pipe cover , the sewage pipe is connected to the production workshop, and a distribution box is installed on the p...
