Description

Sand separator

technical field

The utility model relates to a mixing and separating device, in particular to a sand and gravel separator for separating and recycling waste water and waste residue produced by ready-mixed concrete. the

Background technique

Ready-mixed concrete refers to cement, aggregates, water, admixtures, mineral admixtures and other components that are mixed according to needs in a certain proportion, and is sold at the mixing station after being measured and mixed, and is sold by transport vehicles. Concrete mix transported to the place of use within the specified time.

A large amount of waste water and waste residues are generated during the production of ready-mixed concrete. These waste water and waste residues are usually discharged directly without treatment, causing great pollution to the environment. The existing concrete cleaning and separation equipment has limited separation effect on solids and liquids, and it is difficult to completely separate sand and stones. Not only cannot the recycling of sand and stones be completed, but also the recycling of slurry water, sand and stones cannot be realized, which wastes resources and pollutes the environment. .

In addition, in the process of concrete transportation, residual concrete of mixing equipment, production and construction, it is inevitable to produce excess concrete and the disposal of waste gas concrete that cannot be used due to quality problems. According to statistics, on average, every 100 cubic meters of concrete produced will generate 1 to 1.4 cubic meters That is to say, if the waste concrete is not recycled, it will not only cause a lot of waste of resources, but also pollute the environment and cause public nuisance. The exit of the existing sand and gravel separator is low, easy to block, difficult to disassemble and maintain, easy to block, corrode and damage the inside, and has a low service life.
