Screening device for treating solid waste

Abstract

The invention provides a screening device for treating solid waste. The screening device comprises a rack assembly, a jacking device, a screening barrel, a push assembly, a feeding hopper, a screeningdevice, clamp crushing devices, smashing rollers and a discharging device. The screening barrel is fixedly connected to the top of the rack assembly, the feeding hopper is fixedly connected to the top of the screening barrel, the discharging device is installed in the feeding hopper, the smashing rollers are connected to the left sides and the right sides of the central positions of the upper ends on the front side and the rear side in the screening barrel in a rotating mode, upper end smashing teeth between the smashing rollers are oppositely arranged, the clamp smashing devices are movablyconnected to the left side and the right side at the bottom of the screening device, the push assembly is movably connected to the bottom of the screening barrel, the top of the push assembly extendsinto the screening barrel and is movably connected with the central positions at the bottoms of the clamp smashing devices, the jacking device is fixedly connected to the lower end of the rack assembly, and the top of the jacking device is connected with the bottom of the push assembly. The screening device for treating the solid waste aims to solve the problems that a screen of an existing solidwaste screening device is likely to be blocked, smashing is not thorough enough, and the working efficiency is low.

Description

technical field [0001] The invention relates to the technical field of solid waste processing, in particular to a screening device for solid waste treatment. Background technique [0002] Solid waste refers to solid, semi-solid, and gaseous items placed in containers that lose their original use value or have not lost their use value but are discarded or abandoned during production, living and other activities. Articles and substances that are included in waste management according to administrative regulations; liquid waste that cannot be discharged into water bodies and gaseous substances that cannot be discharged into the atmosphere; due to their greater hazards, they are generally classified into solid waste management systems. [0003] Crushing and screening are required in the process of solid waste treatment, but the currently used solid waste screening devices have the following defects: [0004] 1. The screen is easy to be blocked. [0005] 2. The feeding speed is...
