Concrete sewage sand and gravel separation equipment

Abstract

The application relates to a concrete sewage sand and gravel separation equipment, which includes a frame body, on which a box body is arranged, and the box body includes a first fixed box, a second fixed box and a sliding box, and the top wall of the second fixed box is provided with a Feed pipe, the bottom wall of the first fixed box is provided with an outlet pipe, and the first fixed box is provided with a driving member for driving the sliding box to reciprocate in the first fixed box and the second fixed box, and the sliding box slides along the The height direction of the box is provided with a plurality of filter screens, and the diameters of the filter holes on the multiple filter screens decrease from top to bottom along the height direction of the box body, and each filter screen is arranged in the sliding box in an inclined state. There are openings on the side wall and at the edge of the same side of multiple filter screens. The concrete sewage sand and gravel separation equipment also includes a bearing mechanism for receiving the filtered materials on each filter screen; Advantages of stone separation efficiency.

Description

technical field [0001] The present application relates to the field of concrete treatment equipment, in particular to a concrete sewage sand-stone separation equipment. Background technique [0002] Concrete waste is the most common type of construction waste in construction projects. A concrete company with an annual output of 300,000 cubic meters only cleans the slurry water formed by concrete mixer trucks, which is as high as 80--120 cubic meters per day. The physical pollution of these slurry water is mainly It is the concrete aggregate adsorbed on the tank wall, and the cement, sand and gravel particles produced after washing with water, these particles are insoluble in water and easy to precipitate. In order to prevent the waste of water resources and the pollution of the environment by the sewage slurry produced by the cleaning of concrete mixer trucks by concrete production enterprises, and realize the recycling of concrete sand and gravel separation, people have dev...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: after each completion of the separation of sand and gravel, the entire separation equipment needs to be suspended, and after the separated sand and gravel are discharged along the first discharge port, the next The batch of sand and gravel is transported to the separation cylinder for the next batch of separation, which reduces the separation efficiency of sand and gravel separation
