Technical Field

The invention relates to a concrete plate garbage disposal and recovery device, and belongs to the technical field of garbage disposal.

Background

Along with the rapid development of the construction industry, the amount of construction waste is increased. If the construction waste is not treated in time, the adverse effects can be brought to the society, the environment and the resources. The existing construction waste treatment and recovery is to utilize a crushing and recovery device to produce coarse and fine aggregates from waste construction concrete and waste masonry, and the coarse and fine aggregates are used for producing concrete and mortar with corresponding strength grades or preparing building material products such as building blocks, wall boards, floor tiles and the like. After the coarse and fine aggregates are added into the curing material, the material can also be used for a road surface base layer.

For example, prior patent ZL201910494344.5 discloses a fixed point crushing device for building rubbish concrete reinforcing bar mixed block, and its beat mechanism, fixed point crushing mechanism and supporting mechanism drive the operation of equipment through single motor, further smash tiny concrete through beating the mechanism after fixed point is broken simultaneously, sieve in step, realized fixed point breakage and the effect that the sieve was beaten to the economic benefits and social benefits. However, the construction waste is crushed by pressing the concrete slab with the two fixed crushing rollers, which requires a high-strength crushing roller and a driving structure with larger power, and thus, the equipment cost is high, the crushing efficiency is low, and the energy consumption is high.

For example, patent zl202010745850.x discloses a construction waste treatment device, which puts larger block-shaped construction waste into a large waste treatment frame, and puts smaller waste into a crushing box directly through a receiving hopper, and an output shaft of a motor is used for driving a rotary table and a first belt pulley to rotate simultaneously, the rotary table drives a sliding frame to slide left and right through a connecting rod when rotating, the sliding frame slides left and right through a sliding fit of a first sliding through groove and a first sliding pin when sliding left and right, so that a swing rod is driven to swing left and right based on a central shaft, and the swing rod also drives a movable frame, a movable rod and a crushing plate to move left and right when swinging, so that the larger block-shaped waste can be crushed into smaller crushed materials through right extrusion of the crushing plate, and then the smaller crushed materials are filtered by a steel wire filter screen and fall into the receiving hopper and the crushing box from a discharge port. However, the method can only crush the concrete waste into the framework crushed material with fixed size particles, cannot obtain a material with a larger particle size range, and has low adaptability and low recycling benefit.

In addition, all existing recovery processing devices adopt an electromagnet adsorption mode to recover metal materials such as reinforcing steel bars in concrete, however, the magnet adsorption mode has high power consumption, only magnetic metals can be recovered, and non-magnetic metals cannot be recovered.

Therefore, how to provide a concrete plate garbage disposal and recovery device with high crushing efficiency, wide particle size range of crushed materials and complete recovery of metal materials is one of the technical difficulties which are urgently needed to be solved at present.
