Description

Technical Field

[0001] The utility model relates to the technical field of iron removers, in particular to a permanent magnetic self-unloading iron remover. Background Art

[0002] Self-unloading permanent magnetic iron removers have been widely used in coal, thermal power generation, building materials, mining, metallurgy and other industries, mainly used to remove the iron in block or powder non-magnetic materials. In view of the wide conveyor belt and large material conveying volume in the above occasions, the magnetic system of traditional permanent magnetic self-unloading iron removers is composed of neodymium iron boron, a rare earth material with high coercivity and high remanence. Due to its high magnetic field strength, it is not easy to throw out when a large iron block is adsorbed, which can easily cause the unloading belt to slip, and even pull the belt or damage the motor.

[0003] The prior art discloses a patent with a publication number of CN2649182, in which a driving roller, a driven roller and a roller are installed on the frame, a de-ironing device body is installed below the middle of the frame, a belt with a scraper for unloading iron that rotates around the de-ironing device body is installed on the driving roller, the driven roller and the roller, a main magnetic box for installing a permanent magnetic block is arranged in the shell of the de-ironing device body, and a secondary magnetic box for installing a permanent magnetic block is arranged at a certain distance on the side of the main magnetic box, and the magnetic field polarity of the secondary magnetic box is opposite to that of the main magnetic box. The utility model can easily scrape off the adsorbed miscellaneous iron while ensuring the effect of thoroughly removing ferromagnetic impurities in the material.

[0004] As the existing devices including the above patents are used, the shortcomings of the technology are gradually exposed, mainly in the following aspects:

[0005] First, the existing permanent magnet self-unloading iron remover is provided with a belt to transport and unload the sucked iron objects. This makes the iron remover larger in size due to the limited movement stroke of the belt, and is particularly inconvenient to use in narrow spaces.

[0006] Second, when the existing permanent magnet self-unloading iron remover is used, due to the different iron removal scenarios, it is necessary to adjust the angle and height of the iron remover. Due to the influence of the existing adjustment structure, it is difficult to flexibly adjust the position of the iron remover.

[0007] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] In view of the defects in the prior art, the utility model solves the problem that the permanent magnetic self-unloading iron remover in the traditional technology transports and unloads the sucked iron objects by setting a belt, which makes the iron remover larger in size due to the limited belt movement stroke, and is particularly inconvenient to use in narrow spaces.

[0009] In order to solve the above problems, the utility model provides the following technical solutions:

[0011] The permanent magnet body is connected with a height adjustment component, and the height adjustment component is also used to adjust the inclination angle of the permanent magnet body.

[0012] As an optimized solution, a discharge hole is provided on the side wall of the aggregate box.

[0013] As an optimized solution, a closing plate for opening and closing the discharge hole is hingedly connected to the lower edge of the discharge hole of the collecting box.

[0016] As an optimized solution, a mounting seat is fixedly connected to the outer wall of the permanent magnet body, two connecting plates are fixedly connected to the mounting seat in parallel, and both ends of the lead screw are rotatably mounted on the two connecting plates.

[0017] As an optimized solution, a driving machine is fixedly connected to one of the connecting plates, and an output shaft of the driving machine is fixedly connected to an end of the lead screw.

[0020] As an optimized solution, the upper ends of the two telescopic cylinders are hinged to the top plate, and the upper end of the top plate is fixedly connected with a lifting ear plate.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] Through the forward and reverse rotation of the driving machine, the cleaning plate is driven to move back and forth, and the iron material adsorbed on the lower surface of the permanent magnet body is scraped into the collecting boxes on both sides by the cleaning plate, so that the cleaning plate can move and collect in both directions, and the unloading structure is updated, which overcomes the problem of increasing the volume of the iron remover due to the setting of the belt in the traditional technology, and is especially convenient for use in a narrow space;
