Drain grating pollutant removing device

Abstract

The invention discloses a drain grating pollutant removing device. The drain grating pollutant removing device comprises a shell, a first cylinder, a guide sleeve, a gear rack, pollutant removing mechanisms, a transverse linear module, a vertical plate, a longitudinal linear module, a supporting plate, a second cylinder and a machine frame, wherein the machine frame is fixed to the upper end of asewage tank; the second cylinder drives the pollutant removing mechanisms to move downwards; the transverse linear module and the longitudinal linear module adjust the positions of the pollutant removing mechanisms, so that the axes of the pollutant removing mechanisms are superposed with the axes of liquid flowing holes in a drain grating; the longitudinal linear module drives the pollutant removing mechanisms to move forwards; nail mechanisms fixedly connected with rotating shafts move forwards into the liquid flowing holes; the first cylinder pushes the gear rack to move downwards to driverotating shafts fixedly connected with gears to rotate so as to drive the rake nail mechanisms to rotate, and pollutants are wound and locked in annular grooves formed in rake nails; the longitudinallinear module drives the pollutant removing mechanisms to move backwards to pull out the pollutants on the drain grating. The drain grating pollutant removing device is simple in structure; the pollutants attached to the drain grating can be automatically pulled out without stopping a production line, so that the labor intensity of an operator is effectively reduced and the removal efficiency is improved.

Description

Technical field [0001] The invention relates to a mechanical device, in particular to a dirt blocking grid decontamination device. Background technique [0002] Sewage grille is a treatment facility that intercepts coarse waste water. Sewage grille is mostly used in wastewater pre-treatment operations to intercept large suspended solids and floating objects in wastewater to avoid blocking water pumps and wastewater treatment pipelines. The trash grid is made up of metal rods or grids arranged in parallel at equal intervals in the horizontal and vertical directions. The square holes formed by the metal rods or grids interlaced with each other are liquid flow holes. After long time use, the liquid flow holes After the dirt is wrapped around, the liquid flow aperture becomes smaller, which is not conducive to the flow of sewage. Therefore, it is necessary to decontaminate the trash grid. At present, the production line needs to be shut down when the trash grid is decontaminated, and...

Problems solved by technology

The pollution control grid is made of metal rods or bars arranged in parallel in the horizontal and vertical directions. The square holes formed by the metal bars or bars interlaced with each other are liquid flow holes. After a long time of use, the liquid flow holes The entanglement of dirt around causes the liquid flow aperture to become smaller, which is not conducive to the flow of sewage. Therefore, it is necessary to decontaminate the trash grid. At present, the production line needs to be shut down when the trash grid is decontaminated. Pull out, labor-intensive, low decontamination efficiency
