A magnetic separation device for solid ferromagnetic waste

Abstract

The invention provides a magnetic separation device for solid ferromagnetic waste, which is mainly composed of a feed inlet, a feeding conveyor belt, a metal detection device, a magnetic separation device, a controller, and a motor. The magnetic separation device mainly includes Electromagnetic roller, coil core, electrode end plate and power supply end plate, etc.; the controller can change the magnetic field strength of the coil core according to the amount of ferromagnetic waste detected, but always according to the three-quarter rotation time of the magnetic separation drum The required maximum current detected by the metal detection device in the section is used as the supply current to reliably separate ferromagnetic waste; non-ferromagnetic waste falls directly into the non-ferromagnetic material area due to gravity, and ferromagnetic waste is absorbed by the magnetic field force On the feeding conveyor belt, as the magnetic field force gradually decreases until it disappears, the ferromagnetic waste falls into the ferromagnetic material area, and a magnetic separation is completed so far. The invention reduces energy consumption, protects the environment, effectively avoids the damage of ferromagnetic waste to the incinerator and prolongs the service life of the magnetic separation device.

Description

technical field [0001] The invention relates to a magnetic separation and separation device for solid ferromagnetic waste, which is mainly used for magnetic separation and separation of solid ferromagnetic waste, to save energy, protect the environment, protect the incinerator from damage during the incineration process, and Extend the service life of incinerator and magnetic separation device. [0002] technical background [0003] The solid waste produced in people's daily life pollutes the environment greatly, endangers people's health, and will occupy a large amount of land resources at the same time. In the existing technology, solid waste treatment mainly includes sanitary landfill, composting, and incineration. Among them, incineration has become a more popular treatment method because it can greatly reduce the volume and weight of waste, and can generate clean electricity. Sanitary landfill treatment accounts for about 78% of the treatment volume, and the classificat...
