Description

Realizing roller antifreeze and adhesion device in high-altitude and cold regions Technical Field

[0001] This invention relates to the technical field of roller antifreeze adhesion, and specifically to a roller antifreeze adhesion device for achieving high-altitude and cold-weather conditions. Background Technology

[0002] A conveyor belt is a device that conveys materials by rotating a belt. The belt is driven to rotate by rotating rollers, one end of which is connected to a drive unit.

[0003] When conveyor belts are used in cold regions, the rollers and belts are prone to freezing and sticking, which affects the relative movement of the belt and rollers and seriously impacts the operation of the conveyor belt. Currently, there is no effective technology to solve the problem of roller and belt freezing and sticking. Therefore, for conveyor systems used in cold regions, there is an urgent need for a device that can solve the problem of roller freezing and sticking. Summary of the Invention

[0004] To address the aforementioned problem of rollers easily freezing and sticking when conveyor belts are used in cold regions, this invention proposes a device for preventing rollers from freezing and sticking in cold regions. The device includes a conveying device with two drive rollers for rotating the conveyor belt. Each drive roller has a circulation channel inside, and the two ends of the two circulation channels are connected by a circulation pipe. The circulation pipe and the circulation channels are filled with a heat medium. The circulation pipe is rotatably connected to the drive rollers and is fixedly connected to the conveying device.

[0005] A further provision of the present invention is that the circulation channel is coaxially arranged with the transmission roller.

[0006] A further provision of the present invention is that a heating device is installed on one of the circulation pipes.

[0007] The beneficial effects of this invention are as follows: by connecting the circulation channel and the circulation pipe, the heat medium can circulate inside, further achieving the purpose of heating the roller through the heat medium, thereby avoiding the phenomenon of freezing and sticking on the roller.

[0011] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0012] This invention proposes a device for preventing rollers from freezing and sticking in cold regions. The device includes a conveying device 1, which includes a mounting frame 11 and two transmission rollers 13 for driving belts 12 to rotate. The two ends of the transmission rollers 13 are welded with shaft heads. The transmission rollers 13 are rotatably connected to bearings on the mounting frame 11 through the shaft heads. One end of the conventional roller is connected to a drive device to drive the conventional roller to rotate, thereby driving belts 12 to rotate.

[0013] The transmission roller 13 has a circulation channel 131 inside. The circulation channel 131 is coaxially arranged with the conventional roller. The two ends of the two circulation channels 131 are connected by circulation pipes 2, that is, the two circulation channels 131 are circulated and connected by two circulation pipes 2. The circulation channels 131 and circulation pipes 2 are filled with a heat medium.

[0014] The circulation pipe 2 is fixedly connected to the mounting bracket 11. The circulation pipe 2 is rotatably connected to the transmission roller 13, that is, the rotation of the transmission roller 13 will not drive the circulation pipe 2 to rotate. A heating device 3 is coaxially sleeved on one of the circulation pipes 2. The heating device 3 is used to heat the heat medium in the circulation pipe 2, and then transfer the heat to the inside of the conventional roller through the heat medium to achieve the purpose of heating the transmission roller 13, avoiding the phenomenon of freezing and sticking on the transmission roller 13, and further ensuring the stable operation between the transmission roller 13 and the belt 12.

[0015] It should be noted that a circulation pump also needs to be installed on circulation pipe 2 to drive the hot medium to circulate within circulation pipe 2 and circulation channel 131.

[0016] It should also be noted that the conveying device 1 shown includes multiple drive rollers 13, which can be connected in a serpentine manner through the circulation pipe 2. The circulation channel 131 in the last drive roller 13 can be connected back to the circulation channel 131 in the first drive roller 13 through the circulation pipe 2, thus achieving circulation.

[0017] In summary, by connecting the circulation channel 131 with the circulation pipe 2, the present invention enables the heat medium to circulate within it, thereby achieving the purpose of heating the roller through the heat medium and thus avoiding the phenomenon of freezing and sticking on the roller.

[0018] Although the invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict.
