Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a magnetic separator for rice processing. Background Art

[0002] A magnetic separator is a screening device used to remove iron powder and the like in recycled powdery particles. After the pulp flows into the trough through the feed box, under the action of the water flow of the feed water spray pipe, the ore particles enter the feed area of the trough in a loose state. Under the action of the magnetic field, the magnetic ore particles are magnetically aggregated to form "magnetic clusters" or "magnetic chains". The "magnetic clusters" or "magnetic chains" are affected by the magnetic force in the pulp and move towards the magnetic poles, and are adsorbed on the cylinder. In the processing of rice, a magnetic separator is used to remove sand and gravel in the rice.

[0003] A magnetic separator for rice processing with the publication number CN211514855U exposes the following defects in use:

[0004] Compared with the traditional magnetic separator, the utility model can perform secondary magnetic separation on the sand and gravel in the rice, and has a high efficiency of sand and gravel magnetic separation. Basically, all the sand and gravel in the rice can be magnetically separated, which can meet the production requirements. However, in the actual use process, there is no way to quickly collect the iron filings adhering to the stirring fan blades after adsorption. After multiple uses, it is very likely to affect the actual adsorption and screening efficiency. For this reason, we have proposed a magnetic separator for rice processing.
