Technical Field
[0001] The utility model relates to the technical field of electric rollers, in particular to a combined permanent magnet electric roller. Background Art
[0002] Permanent magnet electric drums, also known as magnetic pulleys or dry bulk magnetic separators, utilize a composite magnetic system composed of high-performance hard magnetic materials. These drums feature high magnetic field strength, deep depth, simple structure, ease of use, no maintenance, low power consumption, and resistance to demagnetization even after years of use. They are used in iron separation applications such as cement, magnetic separation, mining, steel, chemical, refractories, and waste disposal. They can be used in conjunction with fixed belt conveyors to replace drive pulleys, or with specialized belt conveyors.
[0003] An electric permanent magnet roller comprises an oil-cooled motor, a reduction mechanism, an electric roller shell and a rotating shaft. The oil-cooled motor is mounted on the rotating shaft. Both ends of the rotating shaft are connected to both ends of the electric roller shell through end covers. The output shaft of the oil-cooled motor is meshed with an inner gear ring fixed to the inner wall flange of the electric roller shell through the reduction mechanism. An even-numbered polygonal magnetic block mounting cylinder is fixed to the outer wall of the electric roller shell. The outer walls of each side of the even-numbered polygon of the mounting cylinder are connected to permanent magnetic strips through non-magnetic screws, and each permanent magnetic strip is composed of multiple magnetic blocks with consistent polarity directions tightly stacked together.

When damage occurs inside the roller, it cannot be disassembled and repaired, and can only be replaced with a new permanent magnet electric roller, which will cause waste and increase the cost of use. At the same time, when the stator in the existing permanent magnet electric roller operates for too long, its surface temperature will rise, and if it is not cooled in time, it will affect its normal use.

[0025] The insertion rod 6 and the insertion hole 25 are movably connected.
[0026] Through the disassembly and assembly mechanism 2, when damage occurs inside the permanent magnet electric drum, the screw 1 28 and the screw 2 29 can be taken out from the screw hole 1 26 and the screw hole 2 27, so that the connecting cover 21, the connecting ring 22, and the end cover 23 can be separated, and the interior of the permanent magnet electric drum can be disassembled and repaired, thereby reducing the cost of use. Through the cooling mechanism 3, coolant can be added to the inside of the accommodating cavity 34, and the coolant can be used to facilitate cooling of the stator 4. At the same time, the heat conducting plate 31 can play a role in heat conduction, thereby achieving a circulating cooling effect.
[0027] like Figure 3As shown, the disassembly and assembly mechanism 2 includes a connecting cover 21, the bottom end of the connecting cover 21 is movably installed with the left and right ends of the outer shell 1, a connecting ring 22 is installed on the outer side of the front end of the connecting cover 21, and end covers 23 are movably installed on the left and right ends of the outer shell 1. Bosses 24 are symmetrically fixedly installed on the left and right outer walls of the outer shell 1. A socket 25 is provided in the middle of the connecting cover 21, and a plurality of groups of screw holes 26 are equidistantly provided on the surface of the end cover 23. A plurality of groups of screw holes 27 are equidistantly provided in the middle of the connecting cover 21. The internal threads of the screw holes 26 are connected to screw rods 28, and the internal threads of the screw holes 27 are connected to screw rods 29.
[0028] Screw holes 26 are formed at equal intervals on the surfaces of the connecting cover 21 , the connecting ring 22 , and the boss 24 .
[0029] A second screw hole 27 is defined in the middle of the connecting ring 22 .
[0030] By inserting the insertion rod 6 into the socket 25 in the middle of the connecting cover 21, installing the connecting ring 22 and the end cover 23 in sequence, and finally inserting the screw rod 1 28 and the screw rod 2 29 into the screw hole 1 26 and the screw hole 2 27 in sequence, the installation can be completed and it is convenient to use.
