Description

Technical Field

[0001] This utility model relates to the field of rod mill technology, specifically to a rod mill. Background Technology

[0002] Rod mills are named for the steel rods that are loaded into their cylinders as grinding media. They are generally wet overflow type and can be used as primary open-circuit grinding mills. They are widely used in artificial stone and sand, mineral processing plants, chemical plants and power plants for primary grinding.

[0003] In existing technology, rod mills generally do not have a support device on their outer wall, which makes the rod mill prone to complete deformation after long-term operation. In addition, the transmission device of the rod mill needs to be lubricated regularly, and real-time lubrication is not possible, which reduces the overall practicality of the device. Therefore, we propose a new type of rod mill. Utility Model Content

[0041] This utility model provides a technical solution:

[0042] Please see Figures 1-3 A rod mill includes a base plate 1 and two symmetrically arranged fixed plates 2 on its upper end, with a grinding mechanism between the two fixed plates 2.

[0043] The grinding mechanism includes a rotating tube 3 that is rotatably connected to a fixed plate 2. A rod mill body 4 is provided between the two rotating tubes 3. A transmission gear ring 5 is provided on the outer wall of the rod mill body 4. A rotating shaft is rotatably connected to one of the fixed plates 2. A transmission gear 11 that meshes with the transmission gear ring 5 is provided on the outer wall of the rotating shaft.

[0044] Furthermore, one of the fixed plates 2 has a support plate on its side wall, a power motor 6 is provided at the upper end of the support plate, one end of the rotating shaft is connected to the end of the output shaft of the power motor 6, and a turntable 12 is provided at the other end of the rotating shaft.

[0045] Furthermore, two symmetrically arranged horizontal plates 8 are provided between the two fixed plates 2. Two symmetrically arranged mounting seats 9 are provided at the upper end of each of the two horizontal plates 8. Rollers 10 are rotatably connected in each of the mounting seats 9. Two symmetrically arranged mating rings 7 are provided on the outer wall of the rod mill body 4 and cooperate with the rollers 10. By utilizing the cooperation between the rollers 10 and the mating rings 7, a certain support effect is provided on the outer wall of the rod mill body 4, thereby reducing the occurrence of bending deformation of the rod mill body 4 due to excessive load.

[0046] Furthermore, a box 13 is provided at the lower end of one of the horizontal plates 8, and a piston 15 is slidably connected inside the box 13. A drain pipe 18 is provided through one end of the box 13, and the end of the drain pipe 18 is located at the meshing point between the transmission gear ring 5 and the transmission gear 11.

[0047] Furthermore, a through groove 17 is provided at the other end of the housing 13, a rotating seat is provided on the side wall of the piston 15, and a fixed column is provided on the side wall of the turntable 12. The fixed column and the rotating seat are rotatably connected by a rotating plate 16.

[0048] Furthermore, a liquid storage tank 14 is provided at the upper end of the base plate 1, and a connecting pipe is provided at the upper end of the liquid storage tank 14.

[0049] Furthermore, the upper end of the connecting pipe is connected to the housing 13. Both the connecting pipe and the drain pipe 18 are equipped with one-way valves. The two one-way valves operate in opposite directions. By drawing the lubricating fluid from the storage tank 14 into the housing 13, and then squeezing it into the drain pipe 18 through the piston 15, the fluid is then sprayed from the end of the drain pipe 18 between the transmission gear 11 and the transmission gear 5, thereby achieving real-time lubrication of the transmission device and improving the device's self-adaptive capability.

[0050] In practical use, the working principle of this utility model is as follows:

[0051] By setting the rollers 10 inside the two mounting seats 9 on the horizontal plate 8, the rollers 10 and the mating ring 7 are used to provide a certain support for the outer wall of the rod mill body 4, thereby reducing the occurrence of bending deformation of the rod mill body 4 due to excessive load.

[0052] When the rod mill body 4 is in operation, the power motor 6 drives the rotating shaft to rotate, thereby rotating the turntable 12. Utilizing the rotational connection between the turntable 12 and the piston 15 inside the housing 13, the fixed column and the rotating seat, and the rotating plate 16, the rotation of the turntable 12 causes the piston 15 to move back and forth inside the housing 13. Then, by utilizing the cooperation of the connecting pipe and the one-way valve inside the drain pipe 18, the lubricating fluid in the storage tank 14 is drawn into the housing 13, and then squeezed into the drain pipe 18 by the piston 15. Subsequently, it is sprayed from the end of the drain pipe 18 between the transmission gear 11 and the transmission gear 5, realizing real-time lubrication of the transmission device and improving the device's self-adaptive capability.

[0053] In summary, a rod mill, by improving and optimizing its working principle, addresses the problems of reduced adaptability in existing technologies, which lack devices for supporting the rod mill body and for real-time lubrication of the rod mill transmission device.

[0054] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
