A dirt discharge structure on a rake-type grid decontamination machine

Abstract

The invention discloses a dirt discharge structure on a rake-type grid decontamination machine, which comprises a horizontal waste treatment box, the top of the waste treatment box is formed with a conical feeding hopper, and the bottom of the waste treatment box is formed with a Horizontal drainage groove, the waste disposal box is provided with a vertical extrusion plate, the lower end of the extrusion plate is plugged and fixed with several horizontal retaining rods, and the two ends of the retaining rods pass through the left and right sides of the waste disposal chamber. The right two sides are fixedly connected with limit rods; the front side of the top of the extrusion plate is screwed with a horizontal lead screw, and the two ends of the lead screw are plugged into the left and right side walls of the waste disposal box and lean against the limit stop On the plate, a limit baffle is fixed on the left and right side walls of the waste disposal box, and an extrusion motor is fixedly connected to the limit baffle, and the rotating shaft of the extrusion motor is fixedly connected to the lead screw. The invention can squeeze and remove the sundries intercepted by the rake-type grid decontamination machine, and can automatically output the dewatered sundries, thereby improving the efficiency of sewage treatment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment devices, and more specifically relates to a sewage discharge structure on a rake-type grid decontamination machine. Background technique [0002] At present, both domestic sewage and industrial wastewater contain a large amount of floating matter and suspended matter, including inorganic and organic matter, and the content of suspended matter varies greatly; the removal objects of sewage physical treatment are suspended matter and floating matter. Physical treatment can be used alone or in combination with biological treatment or chemical treatment, which is also called primary treatment or primary treatment when used in combination with biological treatment or chemical treatment. At present, the commonly used sewage physical treatment methods are divided into sieve retention method, gravity separation method and centrifugal separation method, and the sieve retention method is mainly gril...

AI Technical Summary

Problems solved by technology

At present, the commonly used sewage physical treatment methods are divided into sieve retention method, gravity separation method and centrifugal separation method, and the sieve retention method is mainly grille and screen mesh. Coarse floating and suspended solids ensure the normal operation of sewage treatment facilities. The grille decontamination machine uses a rotary rake to lift the floating and suspended solids from the grille to the upper end of the decontamination machine for dumping, and then transports them through the conveyor chain belt. Floating and suspended solids output; but it has disadvantages, there is sewage in the floating and suspended solids lifted by the tooth rake, and the floating and suspended solids need to be treated by other equipment for sewage removal, and the sewage will flow to the grille for removal Sewage machine
