Permanent magnet electric drum can be used in cement, magnetic separation, mining, steel, chemical, refractory materials, garbage disposal and other industries. It can be used with fixed belt conveyor to replace the driving wheel, and can also be used with special belt conveyor. Permanent magnet electric drum with non-return function is a special electric drum. In addition to the basic characteristics of permanent magnet electric drum, it also has a non-return function, that is, when the direction of operation of the electric drum is reversed, it can automatically stop or reverse, thereby protecting the equipment from damage or accidents.

[0003] For example, a Chinese patent with publication number CN214717475U discloses a permanent magnet electric roller with a non-return function, including a U-shaped seat and a cylinder, the cylinder is rotatably arranged inside the U-shaped seat, and an iron selection component is arranged inside the cylinder, the iron selection component includes two arc-shaped magnetic steel bars, four oblique magnetic steel bars and two side magnetic steel bars, the two arc-shaped magnetic steel bars are respectively fixedly arranged on the top and bottom of the inner wall of the cylinder, the four oblique magnetic steel bars are respectively fixedly embedded on both sides of the top of the inner wall of the cylinder and on both sides of the bottom of the inner wall, and the two side magnetic steel bars are respectively fixedly embedded in the middle of both sides of the inner wall of the cylinder. The beneficial effects of the utility model are: the cylinder is driven by the output shaft of the driving motor, the cylinder is matched with the double-row roller bearing through the support seat, so as to provide more stable and efficient rolling rotation, and the triangular block, trapezoidal block and reset spring are matched with the outer gear ring, so as to provide a better non-return function and improve work efficiency.

[0004] The existing technology has the following problems:

[0005] In actual use, when the permanent magnet electric drum body is working, its own temperature will rise. As the temperature rises, the magnetic properties of the permanent magnet material will change, resulting in a weakening of the magnetic field strength, thereby affecting the output power and efficiency of the electric drum. At the same time, the permanent magnet material may suffer from thermal demagnetization when working at high temperature for a long time, that is, the permanent magnet material loses part or all of its magnetism at high temperature, and thermal demagnetization is irreversible. Once it occurs, the performance of the permanent magnet electric drum will be permanently degraded. Utility Model Content
