Description

Technical Field

[0001] The present application relates to the technical field of iron removal equipment, and in particular to a self-cleaning rotary iron remover. Background Art

[0002] With the acceleration of industrialization, various materials will inevitably be mixed with ferromagnetic impurities during processing and transportation. These impurities not only affect product quality, but may also cause wear or damage to production equipment, and even cause safety accidents. Therefore, the application demand of iron removers is increasing. By setting up iron removers, ferromagnetic impurities can be effectively removed, product quality and production efficiency can be improved, and equipment failure rate and maintenance costs can be reduced.

[0003] The prior art discloses an iron remover, comprising a frame and a material conveying system for conveying materials, the material conveying system having a material conveying channel, on which at least one iron removal section is arranged; at least one iron removal device, the iron removal device and the iron removal section correspond one to one, the iron removal device comprises an iron adsorption and conveying component, an iron conveying component and an iron collecting trough, the iron adsorption and conveying component has an adsorption station and an iron transporting station, the iron adsorption and conveying component is used to adsorb iron in the material passing through the corresponding iron removal section at the adsorption station, and transport the adsorbed iron to the iron transporting station, the iron transporting component is used to transport the iron at the iron transporting station The iron moves to the iron collecting trough; in the process of conveying materials through the material conveying system, when the material is located in the iron removal section, the iron adsorption and conveying component will adsorb the iron in the material located in the iron removal section, and transport the adsorbed iron to the iron transporting station. At this time, the conveying magnet located at the iron transporting station has magnetism, and the magnetism of the conveying magnet is stronger than the magnetism of the iron adsorption and conveying component adsorbing the iron. The conveying magnet adsorbs the iron here, and then moves the conveying magnet adsorbing the iron to the top of the iron collecting trough through the reciprocating movement mechanism. Then the conveying magnet loses its magnetism, and the iron adsorbed on the conveying magnet falls into the iron collecting trough, completing an iron removal process.

[0004] Regarding the above-mentioned related technologies, since the iron adsorption and transmission components need to work for a long time, the adsorption capacity of their surfaces will decrease due to wear or pollution, resulting in part of the iron in the material cannot be completely adsorbed, affecting the iron removal effect.

[0019] Preferably, a protective cover shell is provided between the left vertical plate and the right vertical plate, the protective cover shell is provided on the plurality of magnetic bars and the fixed plate, and a feed port is also provided on the protective cover shell.

[0020] By adopting the above technical solution, the protective cover shell is set to prevent the staff from direct contact with the high-speed rotating magnetic rod or iron filings on the magnetic rod from splashing during operation or maintenance, which is beneficial to improving the safety of the working environment; the protective cover shell can also effectively isolate dust and pollutants in the external environment, reduce the noise and vibration generated by the equipment during operation, and extend the service life of the equipment.

[0021] Preferably, the scraping assembly includes a push plate, a scraper, an extended scraper sleeve and a pusher;

[0022] The magnetic bar is sequentially arranged through the scraper and the push plate, and the push plate and the scraper are sequentially arranged away from the right vertical plate;

[0024] The pushing member is used to push the pushing plate, the scraping plate and the extended scraping sleeve to move along the length direction of the magnetic rod.

[0025] By adopting the above technical solution, the scraper and the push plate work together to effectively scrape off the iron filings adsorbed on the magnetic bar, ensuring that the iron filings on the magnetic bar are completely removed, thereby maintaining the strength and magnetic force of the magnetic bar, which is beneficial to extending the service life of the magnetic bar, and thus ensuring the continuous iron removal effect of the iron remover; the extended scraper sleeve is convenient for avoiding the accumulation of iron filings at the connection between the magnetic bar and the scraper and push plate, thereby improving the cleaning efficiency of the magnetic bar.

[0026] Preferably, the pushing member includes a first cylinder, a push rod and a movable plate;

When the flap rotates to a certain position, it blocks the discharge port, so that the iron chips adsorbed by the magnetic suction component are discharged through the chip discharge port, while the materials that are not adsorbed are discharged through the discharge port, thereby effectively realizing the automatic separation of iron chips and materials and improving work efficiency. At the same time, since the iron chips are discharged in time, the magnetic suction component can continue to adsorb the iron chips efficiently.

[0039] Preferably, two groups of the second cylinders and the cylinder tie rods are provided, and the two groups of the second cylinders and the cylinder tie rods are symmetrically distributed about the flap.

[0040] By adopting the above technical solution, the two groups of cylinders and pull rods symmetrically arranged about the flap can provide driving force simultaneously and evenly, ensuring that the flap is more stable and balanced during the flipping process, avoiding the flap from deflecting or getting stuck due to uneven force, and helping to improve the stability and reliability of the entire separation assembly; the symmetrical design enables the two groups of cylinders and pull rods to accurately control the flipping angle and position of the flap.

[0042] By adopting the above technical solution, the bearing is arranged outside the protective cover, making the maintenance, inspection and replacement of the bearing easier, which is beneficial to avoid direct contact between the bearing and the material inside the protective cover, thereby reducing the risk of the intermediate push plate bearing being stuck due to the entry of materials and the risk of the bearing being damaged due to contamination.

[0043] Preferably, a gas distribution box is provided on the rack.
