Iron removal device for garbage pretreatment

Abstract

The invention discloses an iron removal device for garbage pretreatment, and belongs to the technical field of garbage treatment. The iron removal device is characterized by comprising a conveying belt, an iron removal device body and a collecting box, the iron removal device body is located above the end of the conveying belt, the collecting box is located on the right side of the end of the conveying belt, and theiron removal device body comprises a rack. When a steel wire rope is wound, the iron removal device body is driven to ascend, and on the contrary, when the steel wire rope is slowly released, the iron removal device body is driven to descend. When the iron removal device body descends, the distance between the iron removal device body and the conveying belt is closer, namely, the magnetic force of an excitation system is improved. When the iron removal device body ascends, the magnetic force of the excitation system is reduced, so that the overall adsorption capacity of the iron removal device is conveniently controlled, adjustment can be conveniently carried out according to actual conditions, the iron removal rate is improved, and the interior of the incinerator operates stably. The invention solves the problems that: an existing iron removal device is generally fixedly installed, the height of a suspended iron remover is inconvenient to adjust, part of magnetic metal at the upper end of a conveying belt cannot be effectively removed, and then stable operation of the boiler is affected.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to an iron removal device for garbage pretreatment. Background technique [0002] Since the 20th century, the discharge of solid waste has increased sharply, resulting in increasingly serious problems such as air pollution, groundwater pollution, soil pollution, land occupation, and natural landscape damage; solid waste is divided into two types: industrial waste and domestic waste; The common treatment methods of waste include landfill, compost, biogas production, sea reclamation, incineration and fluidized bed gas production, etc. Among them, incineration is the best treatment method, which meets the requirements of resource utilization, reduction and harmlessness , and in the garbage pretreatment stage, the magnetic metal in it needs to be removed by the iron removal device.

AI Technical Summary

Problems solved by technology

[0003] Existing iron removal devices are usually fixed installations, and the height adjustment of the suspended iron remover is inconvenient, resulting in the inability to effectively remove part of the magnetic metal on the upper end of the conveyor belt, resulting in a substandard iron removal rate of the waste entering the furnace, which in turn affects the stability of the boiler run
