Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of lubrication adjustment devices, specifically a lubrication adjustment device for a vertical mill. Background Technology
[0002] The lubrication adjustment device for vertical mills is mainly used to ensure good lubrication of various moving parts of the vertical mill, reduce mechanical friction, and extend the service life of the equipment. The lubrication system of a vertical mill generally involves the lubrication of components such as the main shaft, grinding rollers, and grinding disc. It usually uses oil pumps, oil circuit systems, and adjustment devices to achieve the supply and adjustment of lubricating oil. The lubrication adjustment device can accurately adjust the flow and pressure of lubricating oil to ensure that each component that needs lubrication receives sufficient lubricating oil and prevent dry grinding and excessive wear caused by insufficient oil.
[0003] Announcement No. CN222185519U discloses a circulating cooling and lubrication device for grinding roller bearings in a vertical mill. The device includes a lubricating oil reservoir with a main oil pump installed at the bottom. The main oil pump's outlet is connected to a main oil supply pipe, the other end of which is connected to multiple branch oil supply pipes. The lubricating oil reservoir's inlet is connected to a main return oil pipe, the other end of which is connected to multiple branch return oil pipes. An auxiliary oil pump is located between the main oil supply pipe and the main return oil pipe. This invention, by incorporating an auxiliary oil pump, increases the circulation speed of the lubricating oil compared to the main oil pump, thereby increasing the amount of oil flowing through the grinding roller bearing per unit time, meeting the needs for rapid cooling and lubrication. By increasing the circulation speed and the amount of oil per unit time, the heat generated by the grinding roller bearing during operation can be more effectively removed, thus reducing the bearing temperature, extending the equipment's service life, and improving performance.
[0004] The aforementioned patent mentions that the main oil supply pipe delivers lubricating oil to the bearings of each grinding roller shaft through multiple oil supply branch pipes to provide lubrication for the bearings. The used lubricating oil flows back from its respective connected return branch pipes. Multiple return branch pipes converge into the main oil supply pipe and then flow back to the lubricating oil storage tank, completing the circulation of lubricating oil. However, during the circulation lubrication process, the oil flows through the lubricated parts, carrying away the heat and particles generated by friction. At this time, the oil is prone to carrying metal particles, dust, wear substances, and other impurities. The lubricating oil carrying impurities will increase the wear resistance of the lubricating oil. When the lubricating oil flows between the vertical mill parts, it will cause wear on the surface, accelerate the aging and damage of the parts, and shorten the service life of the vertical mill. Therefore, we propose a lubrication adjustment device for vertical mills. Utility Model Content
[0005] The purpose of this utility model is to provide a lubrication adjustment device for a vertical mill, in order to solve the problem mentioned in the background art that during the circulating lubrication process, the oil flows through the lubricated parts, carrying away the heat and particles generated by friction, increasing the abrasiveness of the lubricating oil, causing wear on the surface, accelerating the aging and damage of parts, and shortening the service life of the vertical mill.

One end of the fixed pipe is connected to one end of a connecting pipe. The other end of the connecting pipe is connected to an oil storage tank. The pump body of the oil storage tank is connected to one end of a connecting pipe, and the other end of the connecting pipe is connected to the oil outlet of an oil pump.
[0007] The oil pump inlet is connected to the filter box. A fixed pipe 2 is inserted into one side of the filter box. A screw pipe is sleeved on the outside of the fixed pipe 2. The screw pipe is connected to the filter box. A connecting pipe is sleeved on the outside of the screw pipe. The connecting pipe is fixed to one end of the connecting pipe 3 through a bearing. The connecting pipe 3 is connected to the end of the grinding roller shaft near the oiler.
[0008] Preferably, a connecting pad is bonded to the upper side of the filter box, and the filter box is connected to the box cover. A drive motor is installed on the upper side of the box cover, and an electromagnet is installed on the outer side of the filter box.
[0009] Preferably, a connecting pad is bonded to the upper side of the filter box, and the filter box is connected to the box cover. A drive motor is installed on the upper side of the box cover, and an electromagnet is installed on the outer side of the filter box.
[0010] Preferably, the docking rod is connected to the docking cover, and the docking cover is movably connected to the frame plate of the coarse filter plate through a bearing, and the lower side of the coarse filter plate is fixed to the fine filter plate.
[0011] Preferably, a connecting plate is provided on the lower side of the fine filter plate, and a connecting pad is bonded to the side of the connecting plate near the fine filter plate. The outer side of the docking cover is movably connected to the cleaning brush through a bearing.
[0012] Preferably, the end of the cleaning brush away from the docking cover is fixed to the toothed disc, and the toothed disc is in contact with the toothed ring.

[0014] Preferably, the electromagnet and the magnetic block are magnetically attracted to each other, the docking rod matches the docking cover, the cross-sectional shape of the inner side of the docking cover is rectangular, and the cleaning brush is squeezed against the coarse filter plate.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: When the oil pump is started, the old lubricating oil inside the grinding roller shaft enters the filter box through the connecting pipe, allowing the coarse filter plate to perform preliminary filtration of the oil. When the drive motor is started, the cleaning brush can sweep away the larger particles and impurities trapped by the coarse filter plate, preventing the larger particles and impurities from clogging the coarse filter plate. The preliminarily filtered oil falls to the fine filter plate, allowing the fine filter plate to remove even smaller particles from the oil. This prevents the lubricating oil from carrying impurities when entering the main body of the vertical mill, and makes it less likely to shorten the service life of the main body of the vertical mill when the lubricating oil flows between the main body components.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-6This utility model provides a technical solution: a lubrication adjustment device for a vertical mill, including a vertical mill body 1 and a grinding roller shaft 101. The grinding roller shaft 101 is installed inside the vertical mill body 1. An oil feeder 2 is installed at one end of the grinding roller shaft 101. The oil inlet of the oil feeder 2 is connected to a fixed pipe 201. One end of the fixed pipe 201 is connected to one end of a connecting pipe 202. The other end of the connecting pipe 202 is connected to an oil storage tank 203. The pump body of the oil storage tank 203 is connected to one end of a connecting pipe 204, and the other end of the connecting pipe 204 is connected to the oil outlet of an oil pump 205. The oil inlet of the oil pump 205 is connected to a filter box 206. A fixing tube 207 is inserted into one side of filter box 206. A threaded tube 208 is sleeved on the outside of fixing tube 207. The threaded tube 208 is connected to filter box 206. A connecting tube 209 is sleeved on the outside of threaded tube 208. The connecting tube 209 is fixed to one end of connecting tube 2091 via a bearing. Connecting tube 2091 is connected to the end of grinding roller shaft 101 near oiler 2. A connecting gasket 210 is glued to the upper side of filter box 206. Filter box 206 is connected to cover 211. A drive motor 212 is installed on the upper side of cover 211. An electromagnet 2121 is installed on the outside of filter box 206. A connecting gasket 2120 is glued to the upper side of filter box 206. 0, and the filter box 206 is connected to the box cover 211. A drive motor 212 is installed on the upper side of the box cover 211. An electromagnet 2121 is installed on the outer side of the filter box 206. The docking rod 213 is connected to the docking cover 214. The docking cover 214 is movably connected to the frame plate of the coarse filter plate 215 through a bearing. The lower side of the coarse filter plate 215 is fixed to the fine filter plate 216. A connecting plate 217 is provided on the lower side of the fine filter plate 216. A connecting pad 218 is glued to the side of the connecting plate 217 near the fine filter plate 216. The outer side of the docking cover 214 is movably connected to the cleaning brush 219 through a bearing. The end of the cleaning brush 219 away from the docking cover 214 is connected to the convex... The toothed disc 220 is fixed, and the convex toothed disc 220 is connected to the convex toothed ring 221. The outer side of the convex toothed disc 220 is bonded with a fixing pad 222, and the outer side of the convex toothed ring 221 is bonded with a fixing pad 223. The screw tube 208 and the connecting tube 209 are threadedly connected. The connecting pad 210, the connecting pad 218, the fixing pad 222 and the fixing pad 223 are made of deformable rubber material. The electromagnet 2121 and the magnetic block 2122 are magnetically attracted. The docking rod 213 matches the docking cover 214, and the cross-sectional shape of the inner side of the docking cover 214 is rectangular. The cleaning brush 219 is pressed against the coarse filter plate 215, and the fixing pad 222 and the fixing pad 223 are pressed against each other.
[0025] In specific implementation, according to Figures 1-6When the main body 1 of the vertical mill needs lubrication, the second fixing pipe 207 is inserted into the filter box 206. Simultaneously, the connecting pipe 209 and the screw pipe 208 are rotated together, forming a threaded connection between the screw pipe 208 and the connecting pipe 209, thus binding them together and creating a seal between the connecting pipe 2091 and the filter box 206. Then, the coarse filter plate 215 and the fine filter plate 216 are placed inside the filter box 206, with the fine filter plate 216 adhering to the connecting gasket 218. Next, the box cover 211 is aligned with the filter box 206, pressing the box cover 211 against the connecting gasket 210, while simultaneously pressing the fine filter plate 216 against the connecting gasket 218. Finally, the electromagnet 2121 and the magnetic... Blocks 2122 are fitted together, and the cover 211 drives the docking rod 213 to dock with the docking cover 214. Then, the electromagnet 2121 is energized, and the electromagnet 2121 and the magnetic block 2122 are magnetically attracted, so that the cover 211 and the filter box 206 are bound together. At the same time, the connecting gasket 1 210 and the connecting gasket 218 are made of deformable rubber material, so that the cover 211 and the connecting gasket 1 210 form a sealed state, and the fine filter plate 216 and the connecting gasket 218 form a sealed state. The docking rod 213 and the docking cover 214 remain docked. Then, the pump of the oil supply device 2 and the oil tank 203 are started, so that the lubricating oil inside the oil tank 203 is supplied to the grinding roller shaft 101 through the connecting pipe 1 202 and the oil supply device 2. During lubrication, when the lubricating oil circulates and lubricates the grinding roller shaft 101, the oil pump 205 is started. The old lubricating oil inside the grinding roller shaft 101 is drawn out through connecting pipe 2091 and then fed into the filter box 206 through connecting pipe 2091. At this time, the coarse filter plate 215 can perform preliminary filtration of the oil, removing larger particles and impurities. Then, the drive motor 212 is started, causing its output to rotate the docking rod 213. The docking rod 213 matches the docking cover 214, and the inner cross-sectional shape of the docking cover 214 is rectangular, allowing the docking rod 213 to rotate the docking cover 214. This, in turn, causes the docking cover 214 to rotate the cleaning brush 219, which in turn rotates the cleaning brush 219. The cleaning brush 219 presses against the coarse filter plate 215, allowing it to sweep away larger particles and impurities trapped by the coarse filter plate 215. Simultaneously, the cleaning brush 219 drives the toothed disc 220 to move along the toothed ring 221. The fixing pads 222 and 223, made of deformable rubber, press against each other, causing the toothed disc 220 to rotate as it moves along the toothed ring 221. This rotation of the toothed disc 220 drives the cleaning brush 219, enhancing its cleaning effect and preventing larger particles and impurities from clogging the coarse filter plate 215. The initially filtered oil then flows to the fine filter plate 216, where it removes even finer particles.After filtration, the lubricating oil can re-enter the oil reservoir 203 through oil pump 205 and connecting pipe 204, allowing it to circulate back into the lubrication system. This prevents impurities from being carried into the vertical mill body 1, and reduces the likelihood of accelerated aging and damage to the components as the lubricating oil flows through them, thus preserving the lifespan of the vertical mill body 1.
[0026] In summary, when the vertical mill body 1 needs lubrication, the fixing pipe 207 is installed together with the filter box 206, and the coarse filter plate 215 and the fine filter plate 216 are confined inside the filter box 206. The box cover 211 is also confined together with the filter box 206. Then, the pump of the oil supply device 2 and the oil storage tank 203 is started to lubricate the grinding roller shaft 101 with lubricating oil. When the lubricating oil is circulating and lubricating the grinding roller shaft 101, the oil pump 205 is started to input the lubricating oil into the filter box 206. At this time, the coarse filter plate 215 and the fine filter plate 216 remove particles from the oil. When the lubricating oil flows between the parts of the vertical mill body 1, it is not easy to shorten the service life of the vertical mill body 1. The contents not described in detail in this description are existing technologies known to those skilled in the art.
[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
