Description

Technical Field

[0001] This utility model relates to the technical field of material purification equipment, specifically to a permanent magnet adsorption device for metallic impurities in materials. Background Technology

[0002] During material processing, the introduction of metallic impurities can seriously affect product quality and even damage subsequent processing equipment.

[0003] However, existing permanent magnet adsorption devices have a fixed magnetic field distribution during use, making it impossible to adjust the adsorption intensity and adsorption area according to the particle size, flowability, and metal impurity content of the material. For fine particles, incomplete adsorption is likely to occur, while for large particles, material accumulation and blockage are likely to occur. Furthermore, the adsorbed metal impurities are difficult to clean. Most devices require shutdown and disassembly of the magnets for cleaning, affecting production continuity. A few online cleaning devices use scrapers to remove impurities, which can easily lead to wear on the magnet surface and allow impurities to be mixed into the material again. In addition, the magnets are mostly integral structures, and the entire device needs to be replaced when a single magnet is damaged, resulting in high maintenance costs. Moreover, it is impossible to adjust the magnetic field strength by combining the number of magnets according to actual needs. Therefore, we propose a permanent magnet adsorption device for metal impurities in materials. Utility Model Content

[0004] In view of the problems existing in the permanent magnet adsorption device for metal impurities in materials, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a permanent magnet adsorption device for metal impurities in materials. This solves the problems of existing permanent magnet adsorption devices, which have a fixed magnetic field distribution during use and cannot adjust the adsorption intensity and adsorption area according to the particle size, flowability and metal impurity content of the material. For fine particles, incomplete adsorption is easy to occur, and for large particles, material accumulation and blockage are easy to occur. Moreover, the adsorbed metal impurities are difficult to clean. Most devices require shutdown and disassembly of the magnets for cleaning, which affects the continuity of production. A few online cleaning devices use scrapers to remove impurities, which can easily lead to wear on the surface of the magnets and impurities can easily be mixed into the material again. At the same time, the magnets are mostly integral structures, and the whole device needs to be replaced when a single magnet is damaged, resulting in high maintenance costs. Furthermore, it is impossible to adjust the magnetic field strength by combining the number of magnets according to actual needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A permanent magnet adsorption device for metallic impurities in materials includes a feeding hopper, an adsorption chamber, and a discharging hopper. The adsorption chamber is fixedly installed at the bottom of the feeding hopper, and the discharging hopper is fixedly installed at the bottom of the adsorption chamber. A limiting frame is fixedly installed at one end inside the adsorption chamber. A bidirectional lead screw is rotatably provided between the two sides inside the limiting frame. Both sides of the bidirectional lead screw are threadedly connected to mounting frames. Multiple magnet units are provided inside each of the two mounting frames on opposite sides. Guide rails are fixedly installed on both sides inside the adsorption chamber. Screws are rotatably provided at both ends of the two guide rails. Fixing blocks are threadedly connected to the surfaces of the two screws. Telescopic rods are fixedly installed on the tops of the two fixing blocks. Negative pressure chambers are fixedly installed at the moving ends of the two telescopic rods. Scraper blocks are fixedly installed on the tops of the two negative pressure chambers.

[0009] Preferably, the top of each of the two mounting frames is threaded with a plurality of locking bolts, the bottom of the plurality of locking bolts being tightly fitted with the top of the plurality of magnet units, and the surface of the plurality of magnet units being provided with a wear-resistant ceramic layer.

[0010] Preferably, guide plates are fixedly installed on both sides of the adsorption chamber, a magnetic field strength sensor is fixedly installed on one side of the adsorption chamber, and a flow regulating valve is provided at the bottom of the discharge hopper.

A third motor is fixedly installed on one side surface of the adsorption chamber, and the output end of the third motor is fixedly connected to one end of the bidirectional lead screw.

[0012] Preferably, the surface of the adsorption cavity is provided with a transparent observation window.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model uses a third motor to drive a bidirectional lead screw to rotate, causing the two mounting frames on both sides to move relative to or away from each other, achieving precise adjustment of the spacing between the magnet units. The adsorption area and magnetic field strength can be flexibly adjusted according to the material particle size, flowability, and metal impurity content, effectively solving the problems of incomplete adsorption of fine particles and blockage caused by large particles. Combined with a magnetic field strength sensor for real-time monitoring, the accuracy of magnetic field adjustment is further improved, adapting to various material handling needs. Simultaneously, a combined scraping and negative pressure adsorption cleaning structure is adopted. A second motor drives a screw to move a fixed block, and a telescopic rod adjusts the height of the negative pressure chamber and the scraping block, ensuring the scraping block precisely adheres to the surface of the magnet unit. While scraping away impurities, a negative pressure pump instantly sucks the impurities into a negative pressure collection box through the negative pressure nozzles on the negative pressure chamber and scraping block, preventing secondary mixing of impurities into the material. No machine shutdown or magnet disassembly is required, ensuring continuous production. Furthermore, the magnet unit surface is equipped with a wear-resistant ceramic layer, reducing scraping block wear and extending the magnet's service life.

[0014] 2. In this utility model, the magnet unit is fixed in the mounting frame by locking bolts. If a single magnet is damaged, the corresponding unit can be replaced by loosening the locking bolts directly, without the need for overall replacement, which greatly reduces maintenance costs. The adjustment mechanisms of the device have a simple structure, are easy to operate, and are easy to maintain in the later stages. The transparent observation window allows for real-time observation of the material processing and impurity adsorption in the chamber, enabling timely detection of abnormalities. At the same time, the first motor in the feed hopper drives the rotating shaft and dispersing blades to break up clumps of material, preventing material agglomeration from affecting the adsorption effect. The guide plate inside the adsorption chamber guides the material to flow evenly through the magnet adsorption area, reducing adsorption blind spots caused by material deviation. The flow regulating valve at the bottom of the discharge hopper can adjust the material flow rate according to the adsorption situation, ensuring that metal impurities have sufficient time to be adsorbed, further improving adsorption efficiency.
