[0002] A ball mill is a highly fine grinding machine widely used in industrial production, primarily for crushing and grinding materials. A ball mill's motor drives the rotating drum, creating centrifugal and frictional forces within the drum's grinding media (steel balls or rods), impacting and grinding the material. The material enters the mill uniformly through the hollow feed shaft, where it is subjected to the intense impact and grinding action of the grinding media, ultimately crushing and grinding the material to the desired fineness.

[0026] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0027] Example 1

[0028] As described in the background technology, after a ball mill has been operating for a period of time, the temperature of its end bearings increases, the performance changes, and the service life is reduced. In order to extend the use of the bearings and reduce the probability of the ball mill requiring repair due to bearing damage, this embodiment proposes a new technical solution based on the existing technology. The details are described below.

[0029] like Figure 1 As shown, the existing ball mill includes a barrel 1, a frame 12, bearings, a transmission ring gear, a transmission device, a grinding body device, an electrical device, etc. A material pipe 11 is provided at the end of the barrel 1, which is connected to the frame 12 via a bearing. The transmission ring gear is sleeved on the cylindrical barrel 1. The grinding body device is configured as grinding balls and is arranged inside the cylindrical barrel 1. The electrical device is arranged on the side of the frame 12 and includes a motor, a control device, an instrument, and wires and cables. The transmission device is arranged on the side of the electrical device and includes a reducer, a coupling, a transmission wheel, a pinion, etc. The pinion is meshed with the transmission ring gear. Therefore, the cylindrical barrel can be controlled to rotate when the motor is working, and the grinding balls impact the material to grind it into powder. Because the ball mill is an existing technology, only a brief description is given here. Readers can understand the specific structure of the ball mill through searching.

[0030] like Figure 1 、 Figure 2As shown, in order to achieve the cooling of the bearing and reduce the impact of frictional heat on its service life, a cooling component 2 is provided on the material pipe 11. The cooling component 2 includes a coolant tank 3, a collecting tank 4 and a spraying tank 5. The collecting tank 4 and the spraying tank 5 are both sleeved on the material pipe 11 and distributed on both sides of the bearing. The collecting tank 4 is connected to the coolant tank 3, and the spraying tank 5 is connected to the coolant tank 3 through a driving device. Under the action of the driving device, the coolant in the coolant tank 3 can be forced to be transported to the spraying tank 5 and sprayed on the bearing at the same time, absorbing the heat of the bearing and lowering its temperature. The coolant flowing out of the bearing enters the collecting tank 4 and flows back to the coolant tank 3 to lower the temperature of the coolant. After cooling, it will flow into the bearing again to achieve the cooling treatment of the bearing.

[0031] like Figure 2 、 Figure 5 As shown, the outer diameter of the collecting bin 4 and the spraying bin 5 is larger than the outer diameter of the bearing, and the inner diameter is smaller than the inner diameter of the bearing. The inner diameters of the collecting bin 4 and the spraying bin 5 are equal, thereby completely covering the bearing, providing support for reducing the bearing temperature through the coolant and realizing recycling. Ear plates are provided on the outside of the collecting bin 4 and the spraying bin 5, and the ends of the ear plates protrude from the frame 12. Connecting rods are provided through the ear plates facing the collecting bin 4 and the spraying bin 5. The connecting rods control the collection bin 4 and the spraying bin 5 to be installed in contact with the frame 12, and a sealing layer is provided at the contact point between the collecting bin 4, the spraying bin 5 and the frame 12 to realize the sealed connection between the collecting bin 4, the spraying bin 5 and the frame 12, thereby realizing the circulation of the coolant.

[0032] like Figure 2 As shown, in order to form a coolant circulation channel, a discharge pipe is provided on the collection chamber 4, the lower end of which is inserted into the port of the coolant chamber 3. A liquid infusion pipe 31 is provided on the top of the injection chamber 5. The liquid infusion pipe 31 is connected to the coolant chamber 3 through a driving device. Therefore, the coolant can flow from the bottom of the coolant chamber 3, into the injection chamber 5, pass through the bearing, and then flow into the collection chamber 4. Finally, it is output from the collection chamber 4 and circulated into the coolant chamber 3. The driving device is configured as a liquid pump, such as a gear pump, which forces the coolant to circulate under the action of the liquid pump.

[0033] like Figure 6 As shown, in order to achieve the circulation of coolant and facilitate the removal of the collection bin 4 as needed, the collection bin 4 includes a first half bin 41 and a second half bin 42. The first half bin 41 and the second half bin 42 have the same structure and are symmetrically arranged in the upper and lower parts. A slot 43 and an insertion rod 44 are respectively provided on the sides where the first half bin 41 and the second half bin 42 contact each other. The insertion rod 44 is inserted into the slot 43. Therefore, the first half bin 41 and the second half bin 42 can be placed relatively stably. In addition, the collection bin 4 composed of the first half bin 41 and the second half bin 42 has an opening facing the bearing, that is, it is arranged in contact with the frame 12. In this arrangement, the collection bin 4 is placed adjacent to the main body of the cylinder 1.

[0034] like Figure 7 As shown, the spray bin 5 includes a bin body 51 and a sealing plate 53. The bin body 51 is set as an annular structure, and the side away from the bearing is set as an opening. The sealing plate 53 is set at the opening of the bin body 51 through a bolt connection, and the end of the bolt is inserted into the threaded groove 52. A spray hole 54 is set on the side of the bin body 51 adjacent to the bearing, and the spray hole 54 faces the bearing to facilitate the coolant to flow into the bearing, thereby realizing the cooling of the bearing.

[0035] Example 2

[0036] like Figure 3 、 Figure 4 As shown, based on Example 1, the drive device can be provided with an output pipe 32, a spiral blade 33, and a rotating shaft 34. The spiral blade 33 is mounted on the rotating shaft 34 and is located within the output pipe 32. The rotating shaft 34 extends through the output pipe 32, and the output pipe 32 is connected to the coolant tank 3. A second pulley is mounted on the end of the rotating shaft 34 protruding from the output pipe 32. A first pulley 22 is mounted on the feed pipe 11. The first pulley 22 and the second pulley are connected by a transmission belt 21. When the barrel 1 rotates, the second pulley rotates under the transmission belt 21, forcing the spiral blade 33 to rotate, swirling the liquid and causing it to flow into the bearings, thereby cooling the bearings.

[0037] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
