Description

Background

Coarse aggregate with the grain diameter of more than 4.75mm is used as a raw material in the concrete production, and most of the existing recycled aggregate is obtained by crushing and screening waste concrete blocks. The recycled aggregate is used as the raw material to be continuously put into use, the environment is effectively protected while the problem of shortage of natural resources is solved, the problem of pollution of building rubbish to the environment is solved from the source, and sustainable development is realized.

The environment-friendly low-carbon recycled high-strength concrete raw material processing device according to claim 6, wherein: a gear D is arranged on a rotating shaft B corresponding to the lower end of the roller shaft where the press roller is positioned, the gear D is meshed with a gear E arranged on a rotating shaft C of the inner cylinder, and the rotating shaft C moves in a ring groove A on a corresponding conical ring-shaped channel; the two parts of the outer cylinder separated by the annular groove A are connected through an annular shield A; the rotating shaft C is in transmission connection with an output shaft of a motor C which slides in the shield A around the axis of the outer cylinder; the ring sleeve F which is closed to the ring groove A is rotated in the ring groove B which is communicated with the corresponding ring groove A on the inner wall of the conical ring type channel.

8. The environment-friendly low-carbon recycled high-strength concrete raw material processing device according to claim 6, wherein: gears C are respectively arranged at two ends of the rotating shaft B, and the two gears C are meshed with the two gear rings in the corresponding crushing parts B in a one-to-one correspondence manner.

9. The environment-friendly low-carbon recycled high-strength concrete raw material processing device according to claim 1, which is characterized in that: spiral lines which are convenient for downward discharging are arranged on the inner cylinder wall surface of the discharging channel B; the inner cylinder wall surface of the conical ring-shaped channel communicated with any two adjacent crushing spaces is provided with spiral lines which are convenient for downward discharging.

10. The processing method of the environment-friendly low-carbon regenerated high-strength concrete raw material processing device is characterized by comprising the following steps: 1. under the condition that the retaining ring sleeve D is closed to the discharging channel A and the four ring sleeves E are closed to the lower ends of the corresponding crushing spaces, the motor A, the motor B and all the motors C are started simultaneously, the motor A and the motor B drive the inner cylinder to rotate relative to the outer cylinder, each motor C drives the corresponding compression roller to revolve around the axis of the inner cylinder, and the compression rollers sequentially and reciprocally press the crushing top plates on the corresponding crushing parts B, so that the crushing top plates reciprocate; 2. adding raw materials into a hopper, filtering particles in the raw materials by a cone net, falling into a crushing space at the uppermost end, rotating along with a corresponding crushing part B, effectively crushing the particles into particles with the particle size meeting the composite requirement by a crushing top plate which moves in a reciprocating radial mode under the action of a corresponding compression roller, and intercepting and retaining large particles in the raw materials, which do not meet the crushing requirement, by the cone net; 3. after the raw materials in the uppermost crushing space are crushed, the raw materials sequentially pass through the three crushing spaces below to be crushed, so that the raw materials are crushed according to the final composite particle size requirement; 4. after the raw materials are crushed, the electric putter A drives the annular sleeve D to open the discharge channel A, and after the large particles remained in the cone net are completely discharged through the discharge channel A, the electric putter A is started to drive the annular sleeve D to close the discharge channel A.
