Description

Technical Field

[0001] The utility model relates to the technical field of iron removers, in particular to a disc type electromagnetic iron remover. Background Art

[0002] Electromagnetic iron remover is a device that uses magnetic field attraction to remove ferromagnetic impurities from material conveyor belts. This device will have the following functions during the production process: first, it protects the conveyor belt from damage by ferromagnetic impurities; second, it ensures the safe and stable operation of subsequent important equipment, such as crushers, grinders, boilers, etc.; third, it ensures or improves the quality of related products, such as ceramic products, because ferromagnetic impurities in production will seriously affect the color of the ceramic surface; fourth, it improves the quality of port material transportation to meet customer requirements. Based on the important functions of electromagnetic iron remover, this equipment is widely used in mining, chemical industry, thermal power, cement, glass, ceramics, building materials, food and feed processing, port shipping and other industries.

[0003] The working principle of the electromagnetic iron remover is actually the electromagnetic conversion principle. Theoretically, the electromagnetic attraction of the electromagnetic iron remover is proportional to the square of the current flowing through its coil under a certain power, so the larger the current, the greater the attraction and the stronger the iron removal ability. However, the physical principle also points out that the coil is a resistor. The greater the current, the greater the heat generated and the higher the temperature. The increase in temperature will further increase the resistance of the coil, and the increase in resistance will generate more heat, thus forming a vicious cycle. In this case, there are only two results: one is that the coil or equipment is damaged or burned by high temperature, and the other is that the current is reduced and the iron removal performance decreases.

[0004] A patent with publication number CN204859852U is disclosed in the prior art. The solution includes a circular plate, on which evaporation channels parallel to each other are evenly distributed, the evaporation channels are located between the upper and lower surfaces of the circular plate and penetrate to the circumferential surface of the circular plate, and their axes are parallel to the upper and lower surfaces of the circular plate; a through hole is provided in the center of the circular plate, and the axis of the through hole is perpendicular to the upper and lower surfaces of the circular plate; a hollow ring is provided on the circumference of the through hole, and the evaporation channels penetrating the circumference of the through hole are connected to the inner cavity of the hollow ring; a steam separation ring is provided on the outer circumferential surface of the circular plate, the steam separation ring is a hollow tube, and the evaporation channel ports on the outer circumferential surface of the circular plate are connected to the inner cavity of the steam separation ring; straight finned tubes connected to the inner cavity of the steam separation ring are evenly distributed on the steam separation ring. The utility model has a simple and reliable structure, strong heat transfer capacity and high cost performance. Compared with a radiator composed of independent multiple heat pipes, it has stronger heat dissipation capacity, better temperature uniformity effect, higher processing and installation efficiency, and lower production cost, and is suitable for industrial applications.

[0005] 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:
