Description

TECHNICAL FIELD

[0001] The utility model relates to solid waste recycling device technical field especially relates to a solid waste recycling device of concrete. BACKGROUND

[0002] Recycling concrete solid waste can save natural aggregate resources, reduce land occupation and environmental pollution, and also bring economic benefits. During the recycling of solid waste concrete solid waste, the recycling device plays a key role in the recycling process. It can crush large waste into suitable particles, so that the concrete solid waste can be effectively recycled and utilized.

[0003] For example, the publication number: CN217962663U discloses "a solid waste recycling device for concrete aggregate", which includes a box body, the box body is provided with a first crushing roller and a second crushing roller, the first crushing roller is fixedly provided with a first gear, the second crushing roller is fixedly provided with a second gear matched with the first gear, and the power end of the second gear is provided with a first motor; the bottom of the box body is provided with a first filter plate, a second filter plate and a third filter plate, which are arranged in order from large to small filter holes, the box body is hingedly provided with a baffle matched with the first filter plate, the baffle hinged section is provided with a half gear, the box body is provided with a protection box, the protection box is provided with a rotating shaft, the power end of the rotating shaft is provided with a second motor, the rotating shaft is provided with a third gear meshed with the half gear, and the second filter plate and the third filter plate are also provided with the same components.

[0004] However, in the prior art, when the solid waste of concrete is crushed and recycled, the existing crushing and recycling device cannot adjust the distance between the crushing rollers. When the distance between the crushing rollers cannot be adjusted, it will seriously affect the size requirements of the crushed aggregate. During the recycling of concrete aggregate, different application scenarios have strict regulations on the size of the aggregate. For example, recycled aggregate used for producing high-performance concrete often needs a smaller and uniform particle size range to ensure the good fluidity and strength of the concrete. Since the distance between the crushing rollers is fixed, if the distance is too large, some larger concrete blocks cannot be effectively crushed to the appropriate size. These oversized aggregates cannot meet the fine particle size requirements of the production scene. For example, when used for prefabricated component production, it may cause uneven internal structure of the component, affecting its quality and performance. If the distance is too small, too many aggregates will be crushed too finely, producing too much fine powder. When these aggregates are used for road base laying, the fine particles will affect the drainage and stability of the base, and cannot meet the expected bearing capacity and permeability coefficient and other index requirements. Because too much fine powder will fill the voids between the aggregates, hinder the drainage of water, and reduce the interlocking effect between the aggregates, it cannot meet the precise requirements of different projects for the size of concrete aggregate.
