Construction waste crusher

Abstract

The invention relates to the technical field of construction waste treatment equipment, in particular to a construction waste crusher. The construction waste crusher comprises an external rack, a driving motor and a centrifugal fan. According to the construction waste crusher, a bottom conveying pipe internally provided with a spiral conveying rod and a bottom dust collecting box are mounted in each bottom lifting frame, and a lateral assembling box internally provided with a centrifugal fan is fixed to the outer side of the bottom dust collecting box, so that dust in a crushing and conveying process can be extracted; the air filtering capacity in the operation process of the crusher is greatly improved, so that the crusher is more environment-friendly; the single driving motor is used for synchronously driving crushing cutter bodies and the spiral conveying rod to operate synchronously, the transmission efficiency is high, the structure is simple, and later maintenance is convenient; articles with different masses in the crushed materials can be rapidly separated, the later sorting difficulty is reduced, and the waste treatment efficiency is improved; and the feeding position is changed through inclined guide plates, so that the local service life of the crusher can be prolonged, and the crushing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of construction waste treatment equipment, in particular to a shredder for construction waste. Background technique [0002] Construction waste refers to the dregs, spoils, waste materials, silt and other wastes generated during the construction, laying or demolition, and repair of various buildings, structures, and pipe networks by construction units or individuals. [0003] Classified by source, construction waste can be divided into engineering dregs, decoration waste, demolition waste, engineering mud, etc.; classified by composition, construction waste can be divided into muck, concrete blocks, crushed stones, brick fragments, Waste mortar, mud, asphalt block, waste plastic, waste metal, waste bamboo and wood, etc. [0004] With the acceleration of industrialization and urbanization, the construction industry is also developing rapidly, and the accompanying construction waste is increasing. The amount ...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, provide an improved shredder for construction waste, solve the problem of traditional construction waste The processing method will generate a large amount of dust, which will aggravate air pollution. At the same time, the pulverizer cannot guide and evacuate the pulverized material and the pulverized product, which will have a great impact on the partial service life of the pulverizer, often resulting in serious wear in the middle and a new look on both sides At the same time, the crushed materials cannot be sorted and separated, resulting in the need for manual sorting in the later stage, and the problem of low processing efficiency
