Abstract
Description
Technical Field
[0001] This utility model relates to the field of magnetic separator technology, specifically a drum-type magnetic separator for iron concentrate production. Background Technology
[0002] Magnetic separators are screening devices used to remove iron powder and other substances from recycled powdery granules. After the slurry flows into the tank through the feed box, the mineral particles enter the feed area of the tank in a loose state under the action of the water flow from the feed spray pipe. Under the action of the magnetic field, the magnetic mineral particles undergo magnetic aggregation to form "magnetic clusters" or "magnetic chains". The magnetic clusters or "magnetic chains" are attracted to the magnetic poles by the magnetic force in the slurry and are adsorbed on the cylinder.
[0003] In order not to affect the normal operation of the magnetic separator, the magnetic separator does not have a drum surface cleaning mechanism. When it is necessary to clean the surface of the drum, the magnetic separator must be stopped before tools can be used to clean the impurities on the surface of the magnetic separator drum. This affects the normal operation of the magnetic separator. In addition, the magnetic separator uses a scraper to scrape off the mineral material attached to the magnetic separator drum. As the magnetic separator drum rotates and rubs against the scraper, the distance between the scraper and the magnetic separator drum tends to increase, making it difficult for the scraper to scrape off the mineral material attached to the magnetic separator drum. Utility Model Content
[0004] To address the issue that magnetic separators often lack a drum surface cleaning mechanism to avoid disrupting normal operation, the separator must be stopped before cleaning can be performed, thus affecting its normal operation. Furthermore, the rotating drum and continuous friction between the drum and scraper can increase the distance between them, making it difficult for the scraper to effectively remove the adhering material. The purpose of this invention is to provide a drum-type magnetic separator for iron concentrate production.
[0005] To solve the above technical problems, the present invention adopts the following technical solution: a drum-type magnetic separator for iron concentrate production, comprising a magnetic separator body, a magnetic separator cylinder connected to the magnetic separator body, a cleaning component fixedly provided on the upper surface of the magnetic separator body, and an adjustable scraping component connected to the magnetic separator body;
[0006] The cleaning assembly includes a gantry frame and an arc-shaped plate. The gantry frame is fixedly connected to the upper surface of the magnetic separator body. A double-headed screw is rotatably mounted on the inner surface of the gantry frame. A rectangular sleeve is threaded onto the outer surface of the double-headed screw. The rectangular sleeve slides and fits against the inner surface of the gantry frame. A rotating plate is rotatably mounted inside the rectangular sleeve. The arc-shaped plate slides and fits against the inner surface of the gantry frame. A cleaning brush is fixedly mounted on the inner surface of the arc-shaped plate. The cleaning brush makes movable contact with the outer surface of the magnetic separator cylinder. A fixing block is fixedly mounted on the upper surface of the arc-shaped plate. A fixing block is rotatably connected to the other end of the rotating plate. A drive motor is fixedly mounted on one side of the gantry frame. The output end of the drive motor passes through the gantry frame. A fixing shell is fixedly mounted on one side of the gantry frame. The fixing shell is located inside the drive motor. The output end of the drive motor is fixedly connected to one end of the double-headed screw.
[0007] Preferably, a hollow plate and an arc-shaped scraper are fixedly provided on one side of the magnetic separator body. A screw is rotatably provided on the inner surface of the hollow plate, and a sleeve plate is threadedly fitted on the outer surface of the screw. The sleeve plate slides and fits against the inner surface of the hollow plate. A connecting plate is fixedly provided on one side of the sleeve plate, and the connecting plate penetrates the hollow plate. A notch is opened on the connecting plate.

A bolt is threaded into the connecting block, and the end of the bolt is threaded into the connecting plate. The arc-shaped scraper is movably fitted against the outer surface of the magnetic separator cylinder. A round block is fixedly provided at one end of the screw, and a dial wheel is fitted on the outer surface of the round block. The dial wheel penetrates the hollow plate.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0009] 1. When the magnetic separation cylinder needs to be cleaned, the present invention can start the drive motor to drive the double-headed screw to rotate. The two rectangular sleeves on the outer surface of the double-headed screw move towards the middle. The rectangular sleeves can cause the rotating plate to rotate. The rotating plate can cause the arc plate to move downward. The cleaning brush and the magnetic separation cylinder move downward, so that the magnetic separation cylinder can be cleaned while it is working.
[0010] 2. This utility model allows the circular block to rotate by turning the dial wheel, which in turn drives the screw to rotate, thereby moving the sleeve plate fitted on the outer surface of the screw. The sleeve plate pushes the arc-shaped scraper through the connecting plate, so that the arc-shaped scraper can come into contact with the magnetic separation cylinder and scrape off the residual ore. The distance between the arc-shaped scraper and the magnetic separation cylinder can also be adjusted by increasing it. Attached Figure Description

[0022] Working principle: When the magnetic separation cylinder 12 needs to be cleaned during use, the drive motor 29 can be started to drive the double-headed screw 22 to rotate. The two rectangular sleeves 23 on the outer surface of the double-headed screw 22 move towards the middle. The rectangular sleeves 23 can cause the rotating plate 24 to rotate. The rotating plate 24 can cause the arc plate 26 to move downward. The cleaning brush 27 and the magnetic separation cylinder 12 move downward, so that the magnetic separation cylinder 12 can be cleaned while it is working.
[0023] The circular block 4 can be rotated by turning the dial 41, which in turn drives the screw 32 to rotate. This causes the sleeve 33 fitted on the outer surface of the screw 32 to move. The sleeve 33 pushes the arc-shaped scraper 39 through the connecting plate 34, so that the arc-shaped scraper 39 can come into contact with the magnetic separation cylinder 12 and scrape off the residual ore. The distance between the arc-shaped scraper 39 and the magnetic separation cylinder 12 can be increased for adjustment. The arc-shaped scraper 39 can be replaced by rotating the bolt 38. The connecting block 37 on one side of the arc-shaped scraper 39 can be put into the notch 36 and then connected by the bolt 38.
