Waste recycling equipment for constructional engineering

Abstract

The invention discloses waste recycling equipment for constructional engineering. The waste recycling equipment for constructional engineering comprises a treatment box and feeding nozzles, wherein the upper side wall of the treatment box fixedly communicates with the corresponding feeding nozzles, a plurality of groups of evenly-distributed supporting legs are fixedly arranged on the lower side wall of the treatment box, and a rotating rod is rotationally connected to the side wall of the treatment box; a corresponding crushing roller is fixedly arranged on each rotating rod in a sleeving mode, the two crushing rollers are arranged in a meshed mode, a hollow cylinder is fixedly arranged on the inner wall of the treatment box, a first motor is fixedly arranged on the outer wall of one side of the treatment box, and an output shaft of the first motor inwards penetrates through the side wall of the treatment box and is fixedly connected with a reciprocating screw rod; and a matched bearing is fixedly arranged at the joint of the side wall of the treatment box and the output shaft of the first motor. According to the invention, building waste can be subjected to multi-stage sectional crushing and grinding treatment, treated particle materials are fine, and the materials with too large particles can be collected and automatically subjected to secondary grinding and crushing treatment.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a waste recovery and reuse device for construction engineering. Background technique [0002] In the existing technical field of construction engineering production, the production of building materials, especially the production of concrete blocks, is likely to cause damage to blocks due to bumps during molding, maintenance and handling. Such blocks can no longer be used for masonry, but they can be directly If it is discarded, it will not only pollute the environment, but also lead to an increase in production costs. [0003] Existing waste recycling equipment for construction projects often has certain defects in actual use. On the one hand, the particle size of the crushed material is not fine enough, which often cannot meet the needs of building materials, and for crushed particles that are too large The waste cannot be recycled for secondary crushing. Co...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the defect in the prior art that the crushed waste particles are not fine enough, and the waste with too large particles cannot be recycled to make it secondary crushed, so as to propose a waste recycling equipment for construction engineering
