Vertical electrostatic solid waste sorting machine

Abstract

The invention discloses a vertical electrostatic solid waste sorting machine which comprises a sealed box body, a sorting roller, at least two groups of sorting electrode devices and at least two groups of non-metal discharging devices, the sorting roller is rotationally arranged in the sealed box body, and the at least two groups of sorting electrode devices are arranged in the outer side of the sorting roller in a point symmetry mode; solid waste powder is fed through the upper end of the sealed box body and passes through at least two groups of sorting electrode devices along the outer wall of the sorting roller, the non-metal discharging devices are arranged between every two adjacent groups of sorting electrode devices and located in the outer side of the sorting roller to remove non-metal powder on the outer wall of the sorting roller, each sorting electrode device comprises a plurality of corona electrodes and a plurality of static electrodes, and the corona electrodes are positioned above the static electrodes. According to the invention, large-batch solid waste powder can be subjected to powder sorting from the multi-component sorting electrode device, multiple times of sorting of the powder in a single roller is achieved, the sorting precision is improved, meanwhile, the powder sorting handling capacity is greatly improved, and the sorting efficiency is improved.

Description

technical field [0001] The invention relates to a sorting machine, in particular to a vertical electrostatic solid waste sorting machine, which belongs to the field of solid waste treatment. Background technique [0002] With the development of economy and society, there are more and more solid wastes. If they are not handled properly, they will not only cause great harm to the environment, but also cause waste of resources. At present, it has gradually become the consensus of the society to strengthen the "recycling, reduction, and harmlessness" of solid waste disposal, and at the same time build a resource-saving and environment-friendly society. The first step in the recycling of resources is to separate materials of different uses and values, that is, sorting. For crushed powdery solid waste, such as electronic waste, scrap metal, etc., electrostatic separators can generally be used for sorting. Electrostatic separation is a sorting method that uses the different diele...

AI Technical Summary

Problems solved by technology

[0003] Existing electrostatic separators generally use horizontal drums for sorting, and the feeding method is generally single-line feeding along the length of the horizontal drum, with small processing capacity, and the area of ​​the sorting area on the wall of the drum is small, and a single sorting drum can only Sorting once, low sorting accuracy

However, to achieve multiple separations, it is necessary to increase the number of separation rollers, increasing the energy consumption of the equipment

Although some disc-type electrostatic separation equipment can achieve multiple separations, there are problems such as complex equipment structure, inconvenient maintenance, and difficulty in achieving large-scale promotion and application.
