Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of magnetic material screening, and relates to a magnetic screening device capable of preventing overlapping and suction during transportation. Background Art
[0002] The main raw material of magnetic powder is magnetic powder, which is a ceramic powder made of magnetic material. Magnetic powder is mainly used to manufacture parts of magnets, motors, power equipment and other magnetic devices. Magnetic powder is mainly made of three kinds of magnetic materials, including hard magnetic materials, soft magnetic materials and composite magnetic materials. The magnetic raw material screening device, as a key process equipment, is mainly used to accurately grade and screen the magnetic raw materials to ensure the quality and efficiency of the subsequent production process. However, when this device cannot effectively prevent the occurrence of overlapping suction, it will cause a series of problems.
[0003] First, the phenomenon of overlapping suction will seriously affect the accuracy of screening. In the process of magnetic raw material screening, raw materials of different particle sizes and properties should be accurately distributed to different screening areas. However, the phenomenon of overlapping suction will cause the raw material particles to adhere and accumulate, making it impossible for them to be effectively distributed to their respective screening areas as expected, resulting in inaccurate screening results.
[0004] Secondly, the phenomenon of overlapping suction will also reduce the working efficiency of the screening device. Due to the overlapping suction between the raw material particles, the screening process will become more difficult and require more time and energy to complete. This will not only increase production costs, but also reduce overall production efficiency and affect the economic benefits of the enterprise.
[0005] In addition, the phenomenon of overlapping suction may also cause damage to the screening device itself. Long-term overlapping suction will cause problems such as screen blockage and increased wear, shortening the service life of the equipment. This will not only increase the company's maintenance and replacement costs, but may also affect the company's normal production progress.
[0006] In summary, the inability of the magnetic raw material screening device to prevent the occurrence of overlapping suction will bring many problems, including reduced screening accuracy, decreased work efficiency and equipment damage. Therefore, there is an urgent need for a magnetic screening device that can prevent overlapping suction during transportation to solve the above problems. Utility Model Content
