Concrete tailing cleaning and separating device

Abstract

The invention relates to a concrete tailing cleaning and separating device which comprises a concrete conveying assembly and further comprises a base arranged on the ground, a liftable spraying assembly arranged above the base and a vibration screening mechanism arranged above the base and used for separating out cement, sand and additives in concrete. Firstly, tailings of concrete are conveyed into the vibration screening mechanism through the conveying assembly, the spraying assembly is arranged to be liftable, and the diameter of a screen in the vibration screening mechanism is arranged to be slightly smaller than the particle size of stone; in this way, cement and additives can be rapidly flushed into a collecting hopper in the vibration screening mechanism through vibration of the vibration mechanism and flushing of the upper spraying assembly and then enter a roller from a flow dividing pipe in the vibration screening mechanism. And water generated after the stones are continuously washed subsequently also directly enters the roller from the collecting hopper and the flow dividing pipe to be used for diluting and separating the mixture, namely, all water resources for washing are utilized twice.

Description

Technical field [0001] The present invention belongs to the field of concrete tailstock recovery technology, particularly relates to a concrete tailstock cleaning and separation device. Background [0002] Concrete is mainly made of coarse aggregate (stone), fine aggregate (sand), cement and additives mixed, concrete companies in accordance with the order to mix concrete after each order will have residual tail material needs to be treated separately, as well as concrete mixer trucks in the transport of concrete also often have surplus tailings, and these remaining tails will be handed over to the company that produces concrete, the concrete company's existing main treatment methods are two, one is to use a large amount of water to dilute the tail and flush the tail into the sedimentation tank, so that the tail is recycled in the pool, The recovered tail material is used for the subsequent production of concrete bricks; the second is to use a cleaning and separation device to cl...

AI Technical Summary

Problems solved by technology

In the existing technical scheme, it is mainly carried out by stirring and washing with water. Since the cement and additives in the concrete are cohesive, a large amount of water is required for stirring and diluting, so that it can flow out from the set water outlet. , specifically adding a large amount of water into a stirring container, making the overall volume very large, so that the stirring needs to make a very large energy consumption. In addition, the water outlet hole of the filter must be smaller than the particle size of the sand, so the water outlet Slower, in addition, after the cleaning is completed, it is necessary to screen the stones and sand, so that the whole process makes the cleaning and separation of the concrete tailings take a long time and consume a lot of energy
