Magnetic separation device for solid ferromagnetic wastes

Abstract

The invention provides a magnetic separation device for solid ferromagnetic wastes. The magnetic separation device mainly comprises a feed port, a feeding conveyer belt, a metal detection device, a magnetic separation device, a controller, a motor and the like; the magnetic separation device mainly comprises an electromagnetic roller, a coil iron core, an electrode end plate, a power supply end plate and the like; the controller can change the magnetic field intensity of the coil iron core according to the amount of the detected ferromagnetic wastes, but always uses the maximum current detected by the metal detection device within the time period of three quarters of the rotation of the magnetic separation roller as the supply current, so as to reliably separate the ferromagnetic wastes; and the non-ferromagnetic waste directly falls into the non-ferromagnetic material area due to gravity, the ferromagnetic waste is adsorbed on the feeding conveying belt by magnetic field force, the ferromagnetic waste falls into the ferromagnetic material area along with gradual reduction of the magnetic field force until the ferromagnetic waste disappears, and thus one-time magnetic separation iscompleted. Energy consumption is reduced, the environment is protected, damage of ferromagnetic waste to the incinerator is effectively avoided, and the service life of the magnetic separation deviceis prolonged.

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 capacity, and the classific...
