Classification system for building residue soil

Abstract

The invention provides a classification system for building residue soil. The classification system for the building residue soil comprises a crusher, an iron remover, a water tank and a vibrating screening device, and the crusher, the iron remover, the water tank and the vibrating screening device are connected in sequence. A feed hopper is further arranged at an input end of the crusher, and a sand grain strainer is obliquely installed on the top of the vibrating screening device. A sand collecting box is arranged under the sand grain strainer, and a belt conveyor is connected to the bottomend of the sand grain strainer in the vibrating screening device. An overflow groove is formed in one side of the water tank, and a liquid level valve is arranged on one side of the water tank. A chain wheel conveyor is arranged in the water tank and connected to the input end of the vibrating screening device. The classification system for the building residue soil adopts the integrated compositestructure of the crusher, the iron remover, water concentration equipment and screening equipment, and thus the defect of independent operation in each working procedure in the prior art is overcome,the continuous automatic classification recycling treatment of the building residue soil can be realized, the environmental protection is facilitated, the over structure is scientific and reasonable,simple and compact, the installation and use is convenient, and the operation efficiency is high. The classification system for the building residue soil is widely suitable for the matching use of the classification recycling treatment of the building residue soil.

Description

technical field [0001] The invention relates to garbage sorting equipment, in particular to a building dregs sorting system. Background technique [0002] With the economic development of our country, the construction industry and the real estate industry have developed rapidly, which has brought great changes to our living and working environment, but at the same time of rapid development, it also produces a huge amount of construction waste; Refers to the reinforced concrete blocks, bricks and tiles and other materials produced by demolition of houses in the process of urban construction. Most of the construction waste is transported to the suburbs or mountainous areas without any treatment, and placed in the open air or buried. Soil occupies the land, resulting in a waste of resources, and the dust generated during the transportation and stacking of construction dregs pollutes the air, causing environmental pollution. [0003] Since construction dregs can be effectively ...

[0002] With the economic development of our country, the construction industry and the real estate industry have developed rapidly, which has brought great changes to our living and working environment, but at the same time of rapid development, it also produces a huge amount of construction waste; Refers to the reinforced concrete blocks, bricks and tiles and other materials produced by demolition of houses in the process of urban construction. Most of the construction waste is transported to the suburbs or mountainous areas without any treatment, and placed in the open air or buried. The soil occupies the land, resulting in a waste of resources, and the dust generated during the transportation and stacking of construction dregs pollutes the air and causes environmental pollution. At the same time, the construction dregs will destroy the soil structure and cause surface subsidence

[0003] Since construction dregs can be effectively utilized as renewable resources, water separation or winnowing equipment has also appeared to sort construction dregs, and materials such as plastics, wood, and metal iron can be sorted and recycled, but the existing technology generally uses There are many cases of multiple classification operations and independent operations between each process, and no stable continuous automatic operation has been formed, resulting in a large area occupied by the site and high investment costs. low efficiency
