Waste building material recycling device for building engineering

Abstract

The invention discloses a waste building material recycling device for building engineering. The waste building material recycling device for building engineering comprises an outer box body; a charging pipe is mounted on the top wall of the outer box body; a first discharging pipe is mounted on one side of the outer box body; the bottom end of the outer box body is bucket-shaped; a second discharging pipe is mounted at the bottom end of the outer box body; a first material collecting hopper and a second collecting hopper are mounted in the outer box body sequentially from top to bottom; two grinding tooth rollers which are engaged mutually are arranged between the first material collecting hopper and the second material collecting hopper; and rotating shafts of the two grinding tooth rollers extend to the outer side of the outer box body and are provided with a first motor. According to the waste building material recycling device of the scheme, through arrangement of each structure,the waste building materials can be subjected to crushing treatment; meanwhile, the crushed building materials are sieved and large-particle and powdered building materials are discharged respectively, so that the large-particle and powdered building materials are prevented from being mixed, later batched utilization is facilitated, the utilization rate of the waste building materials is increasedand the utilization value of the building materials is increased.

Description

technical field [0001] The invention relates to the technical field of recycling building materials, in particular to a recycling device for waste building materials used in construction engineering. Background technique [0002] With the vigorous development of construction activities, the consumption of building materials is very large. In order to seek the repeated recycling of building materials, it is necessary to recycle the waste building materials, mainly for the recycling of bricks, stones, concrete blocks, building materials recycling It can be used for backfilling of the foundation layer in the building, or it can be remade into building materials. [0003] In the prior art, the waste gas building materials are generally simply crushed, and then the crushed building materials are reused for foundation backfill or building material remanufacturing. Since the crushed building materials have different particle sizes and contain a large amount of dust, therefore It i...

Problems solved by technology

[0003] In the prior art, the waste gas building materials are generally simply crushed, and then the crushed building materials are reused for foundation backfill or building material remanufacturing. Since the crushed building materials have different particle sizes and contain a large amount of dust, therefore It increases the difficulty of later reuse, so it is necessary to further screen the broken building materials, so as to directly obtain larger particles and dust-like building materials, which is convenient for later reuse of broken building materials. In view of the above problems, we A recycling device for waste building materials used in construction projects is proposed
