Decoration waste resource reutilization disposal system and method

Abstract

The invention discloses a decoration waste resource reutilization disposal system and method. The decoration waste resource reutilization disposal system comprises a bag breaking and screening deviceand a feeding device; the bag breaking and screening device comprises a roller screen body and a plurality of tools; the side wall of the roller screen body is composed of a screen; the multiple toolsare mounted to the side wall of the roller screen body; the decoration waste resource reutilization disposal system further comprises an air separation device used for conducting air separation on oversize products so as to separate light substances with heavy substances, an air distribution device for controlling the air inlet volume and the air outlet volume of the air separation device, a settlement and conveying device for settling and conveying light substances, and a heavy substance discharging device used for outputting the heavy substances. The decoration waste resource reutilizationdisposal method corresponding to the decoration waste resource reutilization disposal system comprises the steps of bag breaking and screening, air separation and screening. The decoration waste resource reutilization disposal system and method which are disclosed by the invention are high in decoration waste separation efficiency and reliability.

Description

technical field [0001] The invention relates to a system and method for resource recycling and disposal of decoration waste. Background technique [0002] At present, there is no effective disposal method for resource recycling of decoration waste in the market. The traditional decoration waste disposal method is to manually sort the decoration waste, and directly landfill the part that cannot be effectively used. [0003] The degree of resource utilization is low, and the inorganic substances with high utilization value in decoration waste have not been effectively utilized as resources. The composition of decoration waste is complex and the bulk density is low. Manual sorting needs to spread the decoration waste, which occupies a large area, and the labor intensity of manual sorting is high, and the efficiency of sorting is low. Landfill disposal costs are high, and landfill disposal is likely to cause land waste and environmental pollution. [0004] A small number of ma...

AI Technical Summary

Problems solved by technology

Among them, broken bags are generally disposed of in the same way as domestic waste, while decoration waste is no different from domestic waste. A large part of decoration waste exists in the form of woven bags when collected, and some of them have been bundled. Woven bags are not like plastic bags. The bags are easy to break, and there are concrete blocks and gravels with high hardness in the bagged decoration waste. If you want to effectively pour out the materials in the bag or break the bag, it is difficult for conventional domestic waste disposal equipment to dispose of large quantities of hard High concrete blocks and crushed stones are easy to damage the blades, while forced crushing equipment such as shredders have limited first processing capacity

The second pair of concrete blocks and crushed stones with higher hardness also tend to reduce the processing capacity and damage the blades, so the overall effect of resource disposal of decoration waste is not good

[0006] Because the decoration waste contains a lot of bagged decoration waste, and the hardness of the concrete block in the bag is relatively high, the forced bag breaking equipment is easy to cause damage to the blade, and the shredding equipment needs to tear the concrete block / stone, which is easy to damage the equipment , and the extrusion crushing equipment is difficult to meet the requirements of bag breaking, and the bagged goods after disposal still do not meet the technical requirements of mandatory bag breaking

[0007] It is difficult to effectively separate long-length substances (such as banners, etc.) in decoration waste;

[0008] The bagged decoration waste is screened or air-selected before the bag is effectively broken and poured out. The air-selection and screening effect is poor, and it cannot meet the production requirements of large-scale decoration waste resource disposal.

[0009] The inorganic matter generated during the disposal process contains many elongated substances, which is not suitable for the transmission equipment in the decoration waste resource disposal line or the disposal cost is high
