Description

Technical Field

[0001] The present disclosure relates to the technical field of magnet protection, and in particular to a permanent magnet iron removal and scale prevention device. Background Art

[0002] In industrial production, scaling and rust problems of equipment have always been important factors affecting production efficiency and product quality. In order to solve these problems, many companies have adopted permanent magnetic iron removal and scale prevention devices. The device uses the magnetic field force of the permanent magnet to adsorb iron and scale in the water flow on the surface of the equipment, thereby achieving the purpose of iron removal and scale prevention. However, different production processes and equipment have different requirements for iron removal and scale prevention. Some equipment needs to operate under high field strength to better adsorb iron; while some equipment needs to operate under low field strength to reduce the impact on the water flow. In order to meet the needs of different equipment, permanent magnetic iron removal and scale prevention devices came into being. Its core component is a variable field strength permanent magnet, which can adjust the magnetic field strength according to actual needs. The magnetic field strength can be adjusted by changing the magnetization direction and magnetization amount of the permanent magnet. When a high field strength is required, the permanent magnet can be magnetized to the maximum value to generate the maximum magnetic field force; when a low field strength is required, the magnetization amount can be appropriately reduced to reduce the magnetic field force. The application of variable field strength permanent magnets allows permanent magnetic iron removal and scale prevention devices to be customized according to actual needs. According to the characteristics and needs of different equipment, the magnetic field strength can be flexibly adjusted to achieve the best iron removal and scale prevention effect. At the same time, the application of variable field strength permanent magnets also improves the adaptability and service life of the equipment, saving costs and human resources for the enterprise. In short, the permanent magnetic iron removal and scale prevention device is an efficient, flexible and adaptable equipment that can meet the needs of different production processes and equipment, and provides a strong guarantee for enterprises to improve production efficiency and product quality.

[0003] A permanent magnetic drum with adjustable magnetic field strength is disclosed in the patent with publication number CN202316111U, which includes a rotatably mounted drum, and a magnetic system is arranged on the inner surface of the drum, and the magnetic system is divided into a weak magnetic field strength area and a strong magnetic field strength area, which are arranged at both ends of the inner surface of the drum, respectively, and there is no magnetic system at the bottom of the inner surface of the drum. The utility model has a simple structure, is easy to carry and transport, and can use different magnetic field strengths according to the rotation direction of the drum, and is easy to operate.

[0004] After being used for a period of time, the variable field strength permanent magnet device of the prior art will cause some iron filings and dust to adhere to the surface due to its magnetic effect, so workers take it out and clean it with an air gun; however, the magnet needs to be disassembled during each cleaning process. For a complex and high-precision device, the disassembly process is very inconvenient, which in turn leads to inconvenience in cleaning the magnet. Utility Model Content
