Concrete classifying and reclaiming system

Abstract

The invention discloses a classified recovery system of concrete, which is characterized in that gravel, sand, mud and water are separated from concrete by a gravel separation device and a sand separation device. A fluid reservoir is arranged at the bottom of the worktable of the gravel separation device while a separator at the top. The feed port of the separator is connected with a tilting chute, and the separator outlet is connected with one end of a conveyor, while the other end of the conveyor is connected with a gravel tank. One end of the sand separation device, which is a fluid conveying pipe, is arranged in the fluid reservoir while the other end is connected with the inlet of a primary cyclone. The fluid outlet of the primary cyclone is connected with the inlet of a secondary cyclone through the fluid conveying pipe while the fluid outlet of the secondary cyclone is connected with a mud tank also through the fluid conveying pipe; the discharge ports of the primary and secondary cyclones are respectively connected with a spiral conveyor located on the top of the worktable through the fluid conveying pipe, and the delivery end of the spiral conveyor is connected with a sand tank. The invention has the advantages of waste reclamation, raw materials saving and environmental pollutions preventing.

Description

Technical field: [0001] The invention relates to a method for sorting and recycling construction garbage, in particular to a concrete sorting and recycling system for saving energy and protecting the environment. Background technique: [0002] As we all know, concrete is the main material of construction, and it is widely used. Concrete is composed of stones, sand, cement and water. Due to the characteristics of cement, concrete will solidify after being relatively static for a certain period of time, so a large amount of Construction waste, transporting concrete mixers and mixer trucks must be cleaned regularly, and a large amount of waste water will also be generated. On the one hand, these construction waste and waste water waste a lot of resources, on the other hand, they cause soil and groundwater pollution. Invention content: [0003] The purpose of the present invention is to overcome above-mentioned deficiencies in the prior art, provide a kind of concrete classifi...
