Description

Technical Field

[0001] The utility model belongs to the field of concrete recycling, and specifically relates to a waste reinforced concrete recycling device. Background Art

[0002] Construction waste refers to the slag, abandoned soil, abandoned materials, sand and gravel and other waste generated during the construction, laying, demolition and repair of various buildings, structures, pipelines, etc. by construction units or individuals.

[0003] The patent application with announcement number CN219291589U discloses a green construction waste recycling device, including: a recycling funnel and a crushing knife group, the recycling funnel is installed on the crushing box, a driving device is arranged on the surface of the crushing box, a crushing knife group is installed in the crushing box, and the lower end of the crushing box is connected to the feed box, the inside of the feed box is connected to the conveyor belt, the lower end of the conveyor belt is connected to the fixed base, and the upper end of the fixed base is provided with a high-pressure water spraying device. In this utility model, a concrete cutting and crushing knife group is designed, which can crush and separate waste concrete, soil blocks and sand and gravel, wherein the separated metal substances are adsorbed on the magnetic magnet rod, and the fine sand is filtered through the sand and gravel filter net, and then the separation box is pulled out to collect the steel bars and small metals. This design further realizes the recycling and reuse of different construction materials, and truly achieves green recycling.

[0004] However, the above technology has the following disadvantages when used:

[0005] As described in paragraph 0028 of the above document, "the separated steel bars are adsorbed by the magnetic magnet rod 902 of the separation box 901 after passing through it, and the remaining concrete fragments fall on the conveyor belt 7. The conveyor belt 7 can convey the concrete that is not completely separated once to the collection box, and then perform secondary treatment on them to improve the recycling rate; when a single pair of construction site soil blocks needs to be recycled, the above steps are repeated, except that after the construction soil blocks are placed in the recovery funnel 3, the high-pressure water spraying device 2 needs to be started, and the high-pressure nozzle 204 connected to the top of the recovery funnel 3 will soften the soil blocks to facilitate the separation of metal blocks mixed therein; and when recycling construction waste sand and gravel, the conveyor belt 7 can be removed, and the above steps are repeated. Finally, after the sand and gravel pass through the crushing box 5 and fall into the separation device 9, the fine sand and gravel will be filtered out through the sand and gravel filter 1001." It can be seen that the incompletely separated concrete needs to be conveyed to the collection frame by the conveyor belt 7. When the concrete is conveyed, there is a problem of concrete accumulation on the outer wall of the conveyor belt 7. If the accumulated concrete is not cleaned in time, the efficiency of concrete transportation will be affected.

[0006] Therefore, a waste reinforced concrete recycling device is proposed to solve the above-mentioned drawbacks. Utility Model Content
