[0019] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0020] See Figure 1 , Figure 2 , Figure 3This is a schematic diagram of the structure of this patent. A self-lubricating device for a rotary kiln support roller includes a fixed plate 1 and a support roller 2. Fixed frames 3 are installed on both the left and right sides of the upper wall of the fixed plate 1. The support roller 2 is rotatably installed between the two fixed frames 3. A lubrication mechanism 4 is installed in the inner cavity of the fixed frame 3.

[0021] The lubrication mechanism 4 can lubricate the connection between the support roller 2 and the fixed frame 3, so that the rotation of the support roller 2 can be smoother.

[0022] The lubrication mechanism 4 includes a groove 41, a ball 42, a flow groove 43, an oil reservoir 44, and an oil pump 45. The inner side wall of the fixed frame 3 is provided with a groove 41, and a ball 42 is installed in the groove 41. The ball 42 can fit against the side wall of the support roller 2. The inner cavity of the fixed frame 3 is provided with a flow groove 43 and an oil reservoir 44. The flow groove 43 and the oil reservoir 44 are connected. The oil reservoir 44 is filled with lubricating oil 5. The side wall of the fixed frame 3 is equipped with an oil pump 45. The input end of the oil pump 45 is inserted into the oil reservoir 44, and the output end of the oil pump 45 is inserted into the flow groove 43.

[0023] The roller 42 functions similarly to the bearing, reducing the friction between the support roller 2 and the fixed frame 3, thus making the rotation of the support roller 2 smoother. At the same time, the lubricating oil 5 can flow in the flow groove 43 and the oil storage groove 44 under the action of the oil pump 45, thereby washing away dust and other impurities on the outside of the connecting shaft 22 of the support roller 2, and preventing dust and other impurities from affecting the smoothness of the support roller rotation.

[0024] The inner wall of the oil storage tank 44 is equipped with a protruding ring 6, the upper wall of the protruding ring 6 is equipped with a filter screen 7, the lower wall of the filter screen 7 is equipped with a connecting ring 8, the side wall of the connecting ring 8 is equipped with a locking block 9, and the inner side wall of the protruding ring 6 is provided with a locking groove 10, and the locking block 9 can be locked into the locking groove 10.

[0025] By using the filter screen 7, the lubricating oil 5 can be lubricated, thereby filtering out impurities in the lubricating oil 5 so that it can be reused.

[0026] The side wall of the fixed frame 3 is provided with a connecting groove 11, which is connected to the flow groove 43. The groove 41 is provided on the inner wall of the connecting groove 11. The support roller 2 includes a support roller body 21 and a connecting shaft 22. The support roller body 21 is equipped with a connecting shaft 22 on both the left and right sides. The connecting shaft 22 is inserted into the connecting groove 11, and the ball bearing 42 can fit against the side wall of the connecting shaft 22.

[0027] A sealing ring 12 is sleeved on the outside of the connecting shaft 22. The sealing ring 12 can be inserted into the connecting groove 11 and can fit against the inner wall of the connecting groove 11.

[0028] By setting the sealing ring 12, external dust can be reduced from entering the connecting groove 11, thus avoiding affecting the rotation of the support roller 2.

[0029] A support roller 13 is installed on the upper wall of the fixed plate 1, and the support roller 13 can fit against the lower wall of the support roller 2;

[0030] The support roller 13 can assist the fixing frame 3 in supporting the support roller 2.

[0031] The side wall of the fixing frame 3 is provided with a through hole 14, which is connected to the inner cavity of the oil storage tank 44. A plug 15 is inserted into the through hole 14.

[0032] New lubricating oil 5 can be injected into the oil reservoir 44 through the through hole 14, and the plug 15 can seal the through hole 14.

[0033] During operation, the roller 2 supports the outer sleeve of the rotary kiln. The roller 2 rotates with the rotary kiln. During rotation, the oil pump 45 pumps the lubricating oil in the oil storage tank 44 into the flow channel 43. Then, the lubricating oil 5 contacts the connecting shaft 22 of the roller 2 to lubricate it and ensure the smooth rotation of the roller 2. The lubricating oil 5 then flows back into the oil storage tank 44, is filtered by the filter screen 7, and is pumped back into the flow channel 43.
