Description

Technical Field

[0001] The utility model relates to the technical field of refractory production, in particular to a magnetic separation device for refractory raw materials. Background Technique

[0002] The refractory castable prepared with corundum as aggregate and powder plus some binders has higher mechanical strength and abrasion resistance than high-aluminum refractory castable and mullite refractory castable, but its thermal shock resistance is slightly worse. It is mainly used as the lining material for various kilns such as boilers, hot blast stoves of blast furnaces, heating furnaces, and ceramic kilns. Among the existing refractories, some powders are magnetic and some are non-magnetic. Therefore, when in use, it is necessary to screen the magnetic and non-magnetic powders.

[0003] The existing technology has the following problems:

[0004] After a large number of searches, it is found that the Chinese patent number: CN217725850U discloses a magnetic separation device for refractories, which includes a working box. The working box is connected with a transmission structure. The transmission structure includes a pair of first transmission rods and second transmission rods respectively rotatably connected to the working box. The first transmission rods are all connected with a feeding structure. The feeding structure includes a first roller and a second roller fixedly connected to the first transmission rod. The first roller and the second roller are connected with a conveyor belt. The second transmission rod is connected with a scraping structure. The scraping structure includes a first rotating column and a second rotating column respectively fixedly connected to the second transmission rod. Magnetic ring sleeves are connected to the first rotating column and the second rotating column. A pair of fixed rods are fixedly connected to the working box. The lower ends of the fixed rods are fixedly connected with a material receiving trough plate. A scraper corresponding to the first rotating column and the second rotating column is connected to the material receiving trough plate, effectively solving the problem of poor magnetic separation effect of the magnetic separation device in the existing technology.

[0005] However, the above patent still has problems in the actual use process. More obviously, the scraper is prone to wear due to friction with the magnetic ring sleeve. Over time, a gap will be generated between the scraper and the magnetic ring sleeve, affecting the cleaning effect and efficiency of the magnetic refractory material.

[0006] Therefore, we propose a magnetic separation device for refractory raw materials to solve the above disadvantages. Content of the Utility Model
