Problems solved by technology

[0005] The above existing technical solutions have the following defects: the prior art adopts the integrated design of sand screening and sand dehydration, and the sand and slurry water directly enter the drum. Due to the high viscosity of the slurry water, the sand, stone, and cement Slurry-water separation is not thorough enough and the separation rate is low

Abstract

The invention relates to a sand and gravel separator, comprising a shell, a drum rotatably connected to the shell with an opening at one end, a first driving assembly for driving the drum to rotate, and one end fixedly connected to the shell and rotatably connected to the drum with an opening The sealing plate is equipped with a feed hopper and a stone discharge hopper below the feed hopper. The side wall of the drum is provided with a first sieve hole for sand to pass through. The inner wall of the drum is provided with a spiral pusher blade. The body is provided with a diversion groove located under the drum, a sand dewatering mechanism located under the diversion groove, and a slurry receiving tank located below the sand dewatering mechanism. The sand dewatering mechanism includes supports respectively located on both sides of the slurry receiving tank. The frame, the sliding part connected to the support frame by sliding in the horizontal direction, the sieving trough installed on the sliding part and the second drive assembly that drives the sliding part to move back and forth. hole. The invention has the effect of improving the separation rate of sand, stone and cement slurry water.

Description

technical field [0001] The invention relates to the technical field of concrete processing, in particular to a sand and gravel separator. Background technique [0002] The commercial concrete mixing station inevitably produces a large amount of wastewater during the cleaning process of the commercial concrete transport vehicle. This wastewater not only contains conventional building materials such as sand and cement, but also contains various types of concrete additives. If it is discharged directly, it will not only cause a waste of building material resources, but also cause serious pollution to the natural environment. Most of the current cleaning wastewater of concrete mixing plants adopts multi-stage slag separation and natural precipitation method for solid-liquid separation. Not only is the treatment efficiency low, but also the settled wastewater cannot be recycled due to the high content of suspended solids. [0003] In recent years, the commercial concrete mixing ...
