Description

An electromagnetic magnetic separation device for processing solid waste

technical field

The utility model relates to an electromagnetic magnetic separation device for processing solid waste, in particular to an electromagnetic magnetic separation device, which is mainly used for the pretreatment of magnetic materials in solid waste, etc., which can prevent the magnetic waste from damaging the incinerator during the incineration process and prolong the The solid waste magnetic separation equipment has a long service life and saves energy.

technical background

Solid waste refers to the solid waste produced by people in daily life. It has complex components, various types and different sizes. If it is not disposed of in time, it will greatly pollute the environment, endanger human health, and also occupy and pollute a large amount of land resources. . There are three main methods of solid waste disposal: sanitary landfill, composting and incineration. At present, sanitary landfill treatment accounts for about 78% of the domestic waste disposal; composting is difficult to form a more effective recycling due to the poor classification and subdivision of waste; incineration can greatly reduce the volume and weight of waste and can be reused. Clean electric energy has become a more popular and popular disposal method due to the prominent waste problem in recent years. Since there are often magnetic wastes such as scrap iron in solid wastes, such wastes should not be used in sanitary landfills and composting, nor should they be treated by incineration, mainly because they will cause serious damage to the incinerator during the incineration process. This kind of ferromagnetic waste must be screened and separated before, which can not only improve the treatment efficiency of subsequent non-magnetic waste, but also recycle scrap iron resources for reuse, which not only saves energy but also protects the environment.

The working principle of the solid waste separation magnetic separation device is to use the magnetic force to absorb and separate the ferromagnetic materials in the solid waste. Existing magnetic separation equipment generally uses permanent magnets to screen and separate ferromagnetic materials from solid waste through the suction of a constant magnetic field (non-magnetic materials are not disturbed by the magnetic field). However, since the permanent magnet is a constant magnetic field and its magnetic field strength does not change, the magnetically selected magnetic waste can only be separated from the magnetic field (ie, separated from the magnetic separation drum) by the strong mechanical action of the scraper. The disadvantage of this method is that the scraper is subject to huge mechanical impact and is easily damaged, and the separation and recovery is difficult and incomplete. It also reduces the working reliability of the magnetic separation equipment and seriously shortens its service life. It also causes serious damage to the incinerator in the subsequent incineration process. damage.

SUMMARY OF THE INVENTION

The utility model provides an electromagnetic magnetic separation device for processing solid waste, which comprises a support, a magnet assembly, an end plate flange, a supply electrode plate, a carbon brush electrode, a power input shaft, a magnetic separation drum, etc. Including electrode lead, connecting shaft, coil and iron core. During the magnetic separation of garbage, the power input shaft drives the end plate flange to drive the magnetic separation drum to rotate, and the solid waste passes through the surface of the magnetic separation drum through the garbage feeding hopper. The garbage falls into the non-magnetic garbage conveyor belt from the surface of the drum under the action of its own gravity; the adsorbed magnetic garbage rotates with the drum, and after passing through the separator, the electrode plate and the carbon brush electrode are separated from the power supply, and this part of the magnetic separation drum The electromagnet inside the electromagnet disappears due to the loss of electricity, and the magnetic garbage adsorbed on its surface falls into the magnetic garbage conveyor belt due to the action of gravity; as the magnetic separation drum continues to rotate, the supply electrode plate and the carbon brush electrode are in contact again. The electromagnet in the area regenerates the electromagnetic force, and the solid magnetic waste can be adsorbed on the surface of the magnetic separation drum again; at this point, a cycle of magnetic separation of solid waste is completed, so that the continuous cycle can complete the magnetic separation of solid waste. Work.
