Description

Technical Field

[0001] The utility model relates to the technical field of magnetic absorption, in particular to a low-waste iron ore concentrate magnetic separator. Background Art

[0002] Magnetic separator is one of the most widely used and versatile machines in the industry. It is suitable for separating materials with magnetic differences. Magnetic separator is widely used in mining, wood, kiln, chemical, food and other industries. In most existing technologies, raw materials are usually put into the magnetic separator through the feed port and attracted by the electromagnetic roller. However, when discharging the material into the magnetic separator, if there are too many raw materials, some of the raw materials may have difficulty in contacting the electromagnetic roller, causing some of the raw materials to fall into the collection box before being attracted, thereby causing a waste of raw materials.

[0003] A search was conducted on the above-mentioned issues and it was found that in the currently disclosed prior art, such as a magnetic separator proposed in publication number CN220547091U, the device installs an averaging plate under the permanent magnet roller, and a plurality of fixed plates are arranged and fixedly installed in the main body. The averaging plate and the fixed plate are elastically connected by springs. During the feeding process, if there is raw material that has not contacted the permanent magnet roller, it will fall onto the averaging plate, and will be bounced back into the permanent magnet roller by the expansion and contraction of the spring for magnetic absorption. However, when the device is feeding, if most of the raw materials are absorbed by the permanent magnet roller and a small part of the raw materials falls onto the averaging plate, due to its light weight, it may be difficult to compress the spring, making it difficult to bounce it up and absorb it again, which may cause insufficient magnetic absorption. Utility Model Content

[0004] The utility model provides a low-waste iron ore concentrate magnetic separator, which solves the problem in the related technology that when feeding, if most of the raw materials are adsorbed by the permanent magnetic roller, a small part of the raw materials falls onto the averaging plate.

[0012] The working principle and beneficial effects of the utility model are:

[0013] 1. In the utility model, the cylinder and the scraper are driven to move forward and backward by the movable frame 2, so that the iron ore concentrate poured into the feeding plate is evenly spread, so that the magnetic absorption mechanism can adsorb the iron ore concentrate more evenly, thus avoiding the poor adsorption effect due to the materials gathering together;

[0014] 2. In the utility model, the feed plate is moved up and down by pulling the connecting rod, so that the distance between the iron ore concentrate on the feed plate and the magnetic absorption mechanism can be adjusted, thereby avoiding the situation that when the iron ore concentrate to be absorbed is small, the distance between the iron ore concentrate and the magnetic absorption mechanism is far, so that the electromagnetic roller weakens the absorption of the material;

[0015] 3. In the utility model, the magnetic absorption mechanism is driven to move forward and backward by the mobile frame, so that the iron concentrate on the feeding plate can be absorbed in all directions, ensuring complete absorption of the material;
