Sand and gravel separation equipment

Abstract

The invention provides sand and rock separation equipment which can recover concrete materials and residual raw materials in cleaning water to effectively save resources, lower the cost and protect the environment. The sand and rock separation equipment comprises a box body and a roller obliquely arranged in the box body and is characterized in that the outer wall of the roller is arranged into a screen mesh, the sand and rock separation equipment further comprises a silo with a feeding convey device arranged therein, one end of the silo is connected with a sieve inlet of the roller, a sand discharging convey device is arranged in the box body and on one side of the roller, a sand outlet is formed in the sand discharging convey device, an overflow port and a rock outlet are respectively formed in the side surface of the box body, and the rock outlet is correspondingly formed at a sieve outlet of the roller.

Description

technical field [0001] The invention relates to the technical field of concrete production equipment, in particular to sand and gravel separation equipment. Background technique [0002] With the increasing demand for ready-made concrete in the construction market, the production of ready-made concrete has become the main building material industry in cities. Compared with the concrete prepared on site, ready-made concrete is of uniform quality, easy to use and does not require builders to purchase additional mixing equipment. Concrete transport vehicles load concrete at the discharge port of the concrete mixing building and transport the concrete to various construction sites. The mixing equipment and concrete transport vehicles have certain discharge residues. In order to prevent the residual concrete from solidifying in the equipment and keep the equipment clean, A large amount of water needs to be used for washing. The water used for washing contains a large amount of co...

Problems solved by technology

Concrete transport vehicles load concrete at the discharge port of the concrete mixing building and transport the concrete to various construction sites. The mixing equipment and concrete transport vehicles have certain discharge residues. In order to prevent the residual concrete from solidifying in the equipment and keep the equipment clean, A large amount of water needs to be used for washing. The water used for washing contains a large amount of construction materials, including insoluble matter such as cement and sand. If it is not disposed of and discharged into the river, it will cause serious pollution and waste a lot of tap water. and concrete materials; at the same time, if the remaining concrete materials are discarded directly after use, it will not only waste resources, but also not conducive to environmental protection
