Description

Technical Field

[0001] This utility model belongs to the field of concrete sand and gravel separation technology, and specifically relates to a concrete waste sand and gravel separation device. Background Technology

[0002] After cleaning, concrete batching plants and their associated mixer trucks generate concrete waste. Concrete waste needs to be separated from concrete slurry and sand using a concrete sand and gravel separator for recycling and reuse. This not only solves the problems of concrete pollution and space occupation, but also saves construction resources in an economical and reasonable way.

[0003] A search revealed a concrete sand and gravel separator (publication number CN219850690U), comprising a separator housing, a screen assembly, and an intermittent lifting assembly. Both the screen assembly and the intermittent lifting assembly are located within the separator housing. The periphery of the screen assembly is attached to the inner wall of the separator housing, and the screen assembly is inclined. The intermittent lifting assembly is located below the screen assembly, enabling intermittent lifting of the screen assembly to cause vibration. A concrete waste inlet is located on the side wall of the separator housing, above the higher side of the screen assembly. The side wall of the separator housing also provides a sand and gravel outlet and a concrete slurry outlet. The sand and gravel outlet is located above the lower side of the screen assembly, and the concrete slurry outlet is located below the lower side of the screen assembly and near the bottom of the separator housing.

[0004] The concrete sand and gravel separator described above uses an intermittent lifting component to vibrate the screen assembly in the separator box, which can separate sand and gravel. However, it still has some shortcomings in actual use. For example, the machine box adopts an integral structure and discharges sand from the discharge port on one side. However, this structure will cause residue to remain at the bottom of the inner side of the machine box and is not conducive to the later maintenance of the intermittent lifting component in the machine box.
