Description

Technical Field

[0001] The utility model relates to the technical field of feeding and screening devices for magnetic separators, in particular to a fast feeding device for magnetic separators. Background Art

[0002] Magnetic separator is a screening device used to remove iron powder from recycled powder particles. After the slurry flows into the tank through the feed box, the ore particles enter the feeding area of ​​the tank in a loose state under the action of the water flow of the feed water pipe. Under the action of the magnetic field, the magnetic ore particles are magnetically gathered to form "magnetic clusters" or "magnetic chains". The "magnetic clusters" or "magnetic chains" are affected by the magnetic force in the slurry and move toward the magnetic poles and are adsorbed on the cylinder. Since the polarity of the magnetic poles is arranged alternately along the rotation direction of the cylinder and is fixed during operation, the "magnetic clusters" or "magnetic chains" produce magnetic stirring due to the alternation of magnetic poles when the "magnetic clusters" or "magnetic chains" rotate with the cylinder. Non-magnetic minerals such as gangue mixed in the "magnetic clusters" or "magnetic chains" fall off during the turning, and the "magnetic clusters" or "magnetic lotuses" that are finally adsorbed on the surface of the cylinder are the concentrates.

[0003] However, the current magnetic separator is troublesome to load, and the slurry is easy to pile up, which makes the magnetic separator unable to effectively screen the raw ore, reducing the efficiency of magnetic separation, and some fine dust is easy to adhere to the surface of the conveyor belt, causing waste of slurry.

[0004] For example, a new type of automatic feeding device for a magnetic separator disclosed in Chinese patent publication number CN213590779U evenly disperses the slurry through the partition in the buffer plate, so that the slurry sent out by the conveyor belt is more evenly dispersed, and the slurry can evenly fall into the magnetic separator, making the screening of the slurry more thorough and improving the effect of magnetic separation. A brush roller is provided to brush off and collect the dusty slurry adhering to the conveyor belt, thereby reducing the waste of slurry.

[0005] The existing technology has the following problems:

[0006] However, there are large particles in the slurry. When the large particles reach the tank body, they may get stuck between the tank body and the magnetic separation roller, causing scratches on the surface of the magnetic separation roller or even damage to the magnetic separation roller, thereby causing mechanical failure and reducing production quality. Therefore, the particle slurry needs to be screened multiple times. Utility Model Content
