Filtering device facilitating clearing of filter residue for chemical industry

Abstract

The invention discloses a filtering device facilitating clearing of filter residue for chemical industry. The filtering device comprises a bottom plate, a cylindrical cylinder is fixed to the top of the bottom plate, and a through hole is formed in the side face of the cylindrical cylinder; a frame and a filtering net are arranged inside the cylindrical cylinder, the filtering net and the inner wall of the frame are fixed, and a rotating rod is fixed to the outer side of the frame and penetrates through the through hole; a driven gear is fixed to the end, away from the frame, of the rotating rod, a supporting frame is fixed to the top of the bottom plate, and a motor is fixed to the top of the supporting frame; and a driving gear is fixed to an output shaft at the output end of the motor,an opening is formed in the side face of the cylindrical cylinder, and a fixed pulley is fixed to the inner bottom of the opening. According to the filtering device, by reversely rotating the filtering net, solid impurities fall from the filtering net through gravity, the filtering efficiency is acceleratedimproved, meanwhile, the solid impurities are quickly transferred through a movable groove plate, and thus the clearing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a filter device for cleaning filter residues in the chemical industry. Background technique [0002] At present, filtration is to force the fluid in the liquid-solid or gas-solid mixture to pass through the porous filter medium, and intercept the suspended solid particles in it, so as to realize the separation of the mixture. It is a unit operation belonging to the fluid power process. Filtration is an industrial production process. In order to remove impurities, a layer of mesh or microporous filter media is often placed at the inlet, especially for sewage treatment in chemical production, but a layer of solid impurities will adhere to the surface of the filter after a long time , It is often not easy to clean, and it will affect the efficiency of liquid filtration. Contents of the invention [0003] The purpose of the present invention is to solve the shortcoming ...
