A method for extracting metal components from solid waste in thermal power plants

Abstract

The invention relates to a method for extracting metal components from solid waste in a thermal power plant, comprising a workbench, a magnetic suction device and a crushing device, the upper end of the workbench is equipped with a magnetic suction device, and the upper end of the magnetic suction device is installed with a crushing device, and the magnetic suction device includes Motor 1, cylindrical box, disc plate, electromagnet, insulating sleeve and feeding pipe. The crushing equipment includes holding cylinder, feeding pipe, motor 2, rotating column, crushing frame, filter plate and control frame, The invention completely pulverizes the solid waste through the pulverization equipment, and filters it, so that the particles that meet the standards enter the magnetic suction equipment for magnetic attraction, and at the same time clean the inner surface of the pulverization equipment to prevent the solid waste particles from adhering to the pulverization equipment On the inner surface, the crushed solid waste is completely magnetically treated by the magnetic suction equipment, and the solid particles and metal particles are transported and collected separately.

Description

technical field [0001] The invention relates to the technical field of waste treatment in power plants, in particular to a method for extracting metal components from solid waste in thermal power plants. Background technique [0002] Thermal power plants are the main body of the country's energy industry, but the solid waste discharged by thermal power plants every year has caused great pressure on the surrounding environment, and at the same time caused a waste of resources, and most of the current waste is landfilled and stacked , The cost of treatment is high, and the waste is serious. Therefore, it is necessary to process and recycle solid waste in order to improve the utilization rate of waste and reduce the discharge of waste. [0003] In the process of extracting metal components, due to the limitation of the physical structure of solid waste, the following problems exist in the actual operation process: [0004] (1) During the crushing process of traditional solid w...

AI Technical Summary

Problems solved by technology

[0004] (1) During the crushing process of traditional solid waste metal component extraction equipment, some solid waste is easily attached to the inner surface of the equipment, which affects the quality of crushing and even affects the subsequent extraction efficiency

[0005] (2) During the extraction process of traditional solid waste metal component extraction equipment, since the solid waste is not easy to completely contact with the magnetic suction parts, the quality of the magnetic suction is low
