AI Technical Summary

Technical Problem

In existing technologies, the cutting effect of the crusher blades is affected by the adhesion of mud and water during the crushing process of tunnel waste, resulting in a decrease in the particle size accuracy of the tunnel waste, and the mud lumps attached to the output material affect the product quality.

Method used

A device for recycling and reprocessing tunnel waste is designed, which consists of a frame assembly, a crushing assembly, and a processing assembly. The crushing gap is controlled by centrifugal screening and hydraulic tilting, and combined with stirring and screening, mud-water separation and efficient crushing of tunnel waste are achieved.

Benefits of technology

It improved the crushing precision and output quality of tunnel spoil, enhanced the particle size control and product precision of tunnel spoil, and realized the efficient reuse of tunnel spoil.

Abstract

The application provides a tunnel-raised tunnel-used waste residue recycling and reprocessing device, and belongs to the technical field of tunnel engineering. The device comprises a frame assembly and a crushing assembly. The side wall and the bottom of the crushing box are designed with separate sieve holes. Most of the mud water flows out of the crushing box. The mud attached to the surface of the tunnel waste residue is separated and falls into the bottom of the crushing box under the impact of the first crushing knife and is collected. The size of the control sieve groove is controlled to perform multi-stage screening of the tunnel waste residue. The side screening discharge design is adopted to screen the tunnel mud water through gravity, which reduces the mixing of mud water during the discharging process, improves the discharging precision and quality of the tunnel waste residue, adopts a centrifugal crushing design, multiple cutters continuously impact the tunnel waste residue to accelerate the separation of mud water, increases the crushing time and crushing impact area of the tunnel waste residue through centrifugal effect, improves the crushing precision and quality of the tunnel waste residue, and the crushing precision of the tunnel waste residue is higher, and the surface quality precision of the tunnel waste residue is better.
