Description

Technical Field

[0001] The utility model relates to the technical field of recycled concrete aggregates, in particular to screening equipment for recycled concrete aggregates. Background Art

[0002] Concrete aggregate is one of the main components of concrete. It refers to the macroscopic material in the shape of particles in the volume after the concrete collapses and solidifies. It usually refers to particles such as crushed stone and pebbles with a particle size greater than 2 mm. Concrete aggregate plays the role of a bridge in concrete, which can bond cement mortar together and increase the strength, hardness and wear resistance of concrete. At the same time, concrete aggregates with different characteristics will also affect other properties of concrete, such as density, water absorption, frost resistance, etc.

[0003] The purpose of screening concrete aggregates is to control the concrete mix ratio, ensure the strength and stability of concrete, screen waste concrete aggregates, reduce the problems of slurry concrete diseases, ensure the quality of concrete construction, select suitable aggregates, and screen them to obtain the best aggregate type. Therefore, screening equipment is needed.

[0004] In the process of screening recycled concrete aggregates by existing screening equipment, when the recycled concrete aggregates fall on the surface of the screening plate, the screening plate that is in a static state for a long time will lead to low screening efficiency. The recycled concrete aggregates are very likely to accumulate on the surface of the screening plate, making it impossible to screen. In addition, during the feeding process, the recycled concrete aggregates are very likely to stick to the inner wall of the feed hopper, which is difficult to clean and will cause a waste of resources. To address this problem, we have proposed a screening equipment for recycled concrete aggregates. Summary of the invention
