Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of magnetic separation equipment, especially to the magnetic separation equipment in the process of removing impurities of industrial silicon micro powder. BACKGROUND

[0002] The magnetic separation equipment in the process of removing impurities of industrial silicon micro powder is a special equipment for separating magnetic impurities in industrial silicon micro powder by using magnetic difference. It is mainly composed of a magnetic source, a roller, a hopper, a collecting device, a transmission device and other parts. Its working principle is that when industrial silicon micro powder containing magnetic impurities passes through the magnetic field area of the magnetic separation equipment, the magnetic impurities will be attracted by the magnetic field, while the non-magnetic silicon micro powder will continue to move forward without being affected by the magnetic field, thereby realizing the separation of magnetic impurities and silicon micro powder.

[0003] The existing removal method is mostly to use a magnet plate to adsorb the iron impurities during the transportation process on the conveying belt. Although this method can separate the iron impurities from the silicon, the overall equipment has a large volume, and it needs to be stopped for operation when collecting the iron impurities, thereby affecting the processing efficiency.

[0004] The existing patent (publication number: CN216224569U) discloses an industrial silicon crushing and impurity removal device, which includes a treatment box, a fixed box is fixedly connected inside the treatment box, a first crushing roller is rotatably connected between the inner walls of the treatment box and inside the fixed box, and a second crushing roller is rotatably connected inside the treatment box and on one side of the first crushing roller. The utility model is simple and convenient to operate, and has high practicality. The first crushing roller cooperates with the second crushing roller to crush the silicon, thereby facilitating the subsequent adsorption of iron impurities. The magnetic roller can adsorb the iron impurities in the silicon during the discharging process. Not only can the volume of the equipment be reduced, but also the magnetic roller can be continuously cleaned with the cooperation of the scraper, thereby ensuring the continuity of the equipment operation and improving the work efficiency.

[0005] In view of the above problems, the existing patent provides a solution. However, in the use of the existing magnetic separation equipment in the process of removing impurities of industrial silicon micro powder, the feeding speed is too fast or the moisture of the material is too large, which can easily cause accumulation and blockage at the feeding port. During the magnetic separation process, the magnetic impurities are adsorbed on the surface of the roller. If the adsorbed impurities are too much and not cleaned in time, they will gradually accumulate, causing blockage in the magnetic separation area.

[0006] Therefore, the magnetic separation equipment in the process of removing impurities of industrial silicon micro powder is proposed. Utility model content
