Solid waste treatment device

By combining support plates, processing boxes, crushing rollers, and hydraulic cylinders, the hydraulic cylinders drive the moving plates and moving teeth to mesh with the crushing rollers, achieving step-by-step crushing of solid waste. This solves the problem that a single crushing method in the existing technology cannot achieve step-by-step crushing, and improves crushing efficiency and particle size control.

AI Technical Summary

Technical Problem

Existing multi-stage crushing devices for solid waste only employ a single crushing method, making it difficult to achieve step-by-step crushing.

Method used

The system employs a combination design of support plate, processing box, first crushing roller, second crushing roller, hydraulic cylinder, moving plate, moving teeth, transmission components and drive components. The hydraulic cylinder drives the moving plate and moving teeth to mesh with the second crushing roller to achieve primary and secondary crushing. It uses the principle of mutual shearing and tearing to crush solid waste in stages.

Benefits of technology

It achieves step-by-step crushing of solid waste, improves crushing efficiency and particle size control, and ensures that the output particle size meets the requirements.

Abstract

The utility model relates to the technical field of solid waste treatment, and discloses a solid waste treatment device which comprises a supporting plate, a treatment box, a first crushing roller, a second crushing roller, a hydraulic cylinder, a movable plate, movable teeth, a transmission part and a driving part. During use, the driving part is controlled to work, and then the second crushing roller can rotate. And then, under the transmission of the transmission part, the second crushing rollers on the two sides can rotate reversely. When the second crushing rollers on the two sides rotate reversely, the solid waste can be crushed for the first time according to the mutual shearing and tearing principle between the two crushing rollers rotating oppositely. And after the solid waste subjected to primary crushing falls under the action of gravity, the hydraulic cylinder is controlled to work, so that the movable plate moves towards the second crushing roller, the falling solid waste is pushed to move, and a plurality of movable cutters are engaged with crushing teeth of the second crushing roller. At the moment, the interaction of the multiple movable cutters and the second crushing roller can be utilized, solid waste obtained after primary crushing is shredded, sheared and extruded to be machined to be smaller in particle size, and step-by-step crushing is achieved.
