Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separators, in particular to a cleaning device for a vertical ring high gradient magnetic separator. Background Art

[0002] The vertical ring high gradient magnetic separator is one of the main methods for wet separation of weak magnetic ores and purification of non-metallic ores. Its principle is to use the magnetic field generated by the winding coil and form a magnetic field loop through the upper and lower magnetic yokes. A rotating ring is set between the upper and lower magnetic yokes and the winding coils and a magnetic medium is installed. The lower part of the rotating ring is immersed in the ore pulp. Relying on the rotation of the rotating ring, the magnetized medium adsorbs the magnetic particles of the mineral on the surface of the magnetic medium. When the rotating ring drives the magnetic medium immersed in the ore pulp to leave the ore pulp and turn a certain angle, the pressure water set on the top of the rotating ring will flush the magnetic ore particles into the collection box to achieve the separation of the ore. With the increase of working time, the yoke seams of the upper and lower magnetic yokes are easily blocked by debris and iron ore attachments. At this time, in order to ensure the normal production of the vertical ring high gradient magnetic separator, the yoke seams of the upper and lower magnetic yokes need to be cleaned. At present, it is manually disassembled, that is, the cleaning operation can only be carried out after the rotating ring is removed. Not only is the maintenance efficiency low, but also the maintenance cost is high. Utility Model Content

[0003] The utility model aims to provide a cleaning device for a vertical ring high gradient magnetic separator, which can improve the maintenance efficiency and reduce the maintenance cost, in view of the shortcomings of the prior art.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the cleaning device of the utility model vertical ring high gradient magnetic separator is:

[0005] A cleaning device for a vertical ring high gradient magnetic separator comprises a box body, a mounting plate is arranged in the box body, cleaning brushes are arranged on the top and bottom surfaces of the mounting plate for cleaning debris in a yoke gap, a plurality of strong magnetic blocks connected in series are arranged on both sides of the mounting plate on the cleaning brush for adsorbing iron ore attachments in the yoke gap, storage space for iron ore attachments is left between the strong magnetic blocks on the top surface of the mounting plate and the top surface of the box body, and storage space for iron ore attachments is left between the strong magnetic blocks on the bottom surface of the mounting plate and the bottom surface of the box body.

[0006] Preferably, the strong magnetic block is provided with a plurality of countersunk holes.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] 1. When maintaining the standing ring high gradient magnetic separator, first remove the magnetic medium continuously arranged along the axis of the rotating ring, replace it with the utility model, rotate the rotating ring back and forth repeatedly, use the cleaning brush to clean the debris in the yoke seam, and at the same time, the strong magnetic block absorbs the iron ore attachment in the yoke seam. The operation is very convenient, the maintenance work is efficient and the cost is low.

[0012] 2. The countersunk hole can be used to insert bolts to fix the strong magnetic block on the mounting plate to prevent the strong magnetic block from being thrown away during the rotation of the swivel; the countersunk hole can further improve the adsorption capacity of the strong magnetic block.

[0016] The present invention is further explained below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that these implementation methods are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0017] like Figure 1-2 As shown, a cleaning device for a vertical ring high-gradient magnetic separator comprises a box body 1. The box body and the magnetic medium have the same specifications and can be directly replaced by using the mounting holes of the magnetic medium. A mounting plate 2 is fixedly connected to the box body by flat-head bolts. A cleaning brush 3 is installed on the top and bottom surfaces of the mounting plate. The cleaning brush comprises a brush plate 31. The brush plate is detachably connected to the mounting plate by flat-head bolts for easy replacement. Bristles 32 are fixedly connected to the top surface of the brush plate. The bristles are made of stainless steel and protrude from the box body.
