Construction waste crushing device

Abstract

The invention relates to the technical field of construction engineering waste disposal, in particular to a construction waste crushing device. The construction waste crushing device comprises a crushing box. A conical feeding opening is formed in the middle of the upper end of the crushing box, a discharging opening is vertically downwards formed in the left side of the lower end face of the crushing box, a screening base is arranged at the lower end of the crushing box, and a pair of fixed crushing rollers which are symmetrical up and down are arranged on the left side of an inner cavity ofthe crushing box. The construction waste crushing device has the beneficial effects that: a crushing mechanism is used for crushing construction waste, the construction waste is further rolled into small particle powder, and a foundation is provided for subsequent classification on conveyor belts; the multi-stage conveyor belts are used for classification, and grading of particles of different sizes is realized; and through step-by-step vibration of different vibration mechanisms, the falling effect and screening efficiency of the particles are enhanced, the design of the different vibration mechanisms leads to different vibration effects, and thus high recovery-rate screening of different classified substances can be realized.

Description

technical field [0001] The invention relates to the technical field of construction waste treatment, in particular to a construction waste crushing device. Background technique [0002] Construction engineering refers to the planning, survey, design and construction, completion and other technical work and the completed engineering entity and the installation project of the supporting lines, pipelines and equipment for new construction, reconstruction or expansion of houses, buildings and auxiliary structures and facilities. , also refers to the construction projects of various houses and buildings, also known as the construction workload. This part of the investment amount must be constructed and driven, and can only be realized through construction activities. [0003] In construction projects, a large amount of construction waste will inevitably be produced, including excavated muck, concrete blocks, stones, brick fragments and asphalt blocks, etc. Construction waste has ...

AI Technical Summary

Problems solved by technology

Since these construction wastes have a certain hardness and are large in size, it would be time-consuming and labor-intensive to process them directly.

[0004] At present, there are similar crushing devices, but there are no related classification components. Generally, the crushed construction waste can only be used for landfill, but the crushed classification can be processed into new concrete bricks, flowers and plants after adding auxiliary materials. Bricks, etc., 0-3mm can be used for the foundation cushion, and 0-12mm can be used for environmental protection unburned bricks, hollow bricks, pavement bricks, grass planting bricks, lattice bricks, etc.
