Novel concrete gravel-sand separation device

Abstract

The invention relates to a novel concrete gravel-sand separation device. The novel concrete gravel-sand separation device comprises a washing tank, a vibrating sieve, a screw sand separator, a mortar pool, a water pump and an agitation pool and is characterized in that the washing tank is connected with the vibrating sieve, residual concrete in an agitating truck is discharged into the washing tank and then flows onto the vibrating sieve which is positioned above the mortar pool, the water pump is positioned in the mortar pool, a discharging port of the water pump is connected with the screw sand separator, a water outlet of the screw sand separator is connected to the agitation pool, and a vibrating motor and a screen are arranged on the vibrating sieve. By means of high-efficiency vibration of the vibrating sieve, sand and gravels in concrete can be thoroughly separated, the separated sand and gravels are flushed by a high-pressure flushing device, and accordingly low mud content and moisture content are realized, and standards of gravel aggregates for building concrete can be met; residual mortar can be recycled directly, and accordingly zero emission of waste residues and waste water of a concrete batching plant is realized truly.

Description

technical field [0001] The invention relates to a novel concrete sand-stone separation device, in particular to a sand-stone separation device for a concrete mixing station. Background technique [0002] Most of the currently used sand and gravel separators are drum screen separators, which mainly separate sand and stones through drum screens, and then transport sand and stones to the two ends of the separator through two reverse spirals for discharge. However, the mud content and water content of the sand and stone separated by the separator of this structure are very high. At the same time, the sand and stone cannot be completely separated. The stone is often wrapped with a large amount of fine sand, which is added to the production of concrete as aggregate. It will seriously affect the quality of concrete. Contents of the invention [0003] In order to better solve the above problems, the present invention provides a new type of concrete sand and gravel separation devi...
