Description

Technical Field

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

[0002] Electromagnetic iron remover is an electromagnetic device used to remove iron pieces from bulk non-magnetic materials. It is usually installed at the head or middle of the belt conveyor. The strong magnetic force generated by power on will suck up the iron pieces mixed in the material and throw them out by the unloading belt, achieving the purpose of automatic removal. It can also effectively prevent the conveyor belt from longitudinally scratching and protect the normal operation of crushers, grinders, flat iron removers, etc. Iron removers are widely used in food, electricity, mining, metallurgy, building materials, coal preparation, chemical industry and other departments. However, the existing technology has large vibration, insufficient stability and insufficient magnetism when working.

[0003] The prior art discloses a patent with publication number CN207204364U, which includes a frame, support legs, an electric control box, a power cord, a pulley, an iron unloading belt, a driving motor, a chain cover, an iron remover body, a shock absorber, a magnet, a chain, a cable, an electromagnet, and low-carbon steel. Support legs are arranged at the bottom around the frame and welded to the support legs. The electric control box is arranged at the right end of the frame, and the right end of the electric control box is electrically connected to the power cord. The front and rear ends of the pulley are fixed to the left and right ends of the bottom of the frame, and an iron unloading belt is arranged outside the pulley. By arranging a shock absorber at the bottom of the support leg, the vibration caused by the motor during operation is reduced, the stability is improved, and the problems of large vibration and insufficient stability during operation are solved. By arranging a magnet at the top of the iron remover body, the magnetism of the iron remover body is increased, the iron substance in the material can be effectively absorbed, and the problem of insufficient magnetism is solved.

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

[0005] First, the existing electromagnetic self-unloading iron remover uses a belt to transport and unload the sucked iron objects. Due to the friction contact between the belt and the adsorption section of the electromagnet body, the belt is prone to breakage due to wear as it is used, shortening its service life.

[0006] Second, when the existing electromagnetic self-unloading iron remover is used, the direction of the unloading end is fixed and cannot be adjusted according to the position and height of the receiving equipment, so the operator is required to perform secondary material transfer, which increases the labor intensity.

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