Description

Technical Field

[0001] This invention relates to the field of temperature measurement in thin oil stations, specifically a temperature measuring device for a lubrication system in a thin oil station. Background Technology

[0002] A thin oil station is a machine used for thin oil lubrication in metallurgical equipment. It is the heart of the thin oil circulating lubrication system, and its function is to force the lubricating oil to the friction parts of the machine. Thin oil stations are mainly used in the centralized lubrication system of moving, stationary or sliding bearings of mechanical equipment in metallurgy, mining, cement and other industries. They are usually installed in underground oil depots or pits near the machine.

[0003] In existing technology, when a thin oil station is working, the oil is drawn from the oil tank by a gear pump, passes through a one-way valve, a double-cylinder mesh filter, and a shell-and-tube cooler, and is directly sent to the lubrication parts of the equipment to lubricate the relatively moving parts and carry away the metal particles worn during movement. Then, it passes through a magnetic filter to remove magnetic iron filings and abrasives, and returns to the oil tank, forming a thin oil circulation lubrication system. After the oil returns to the oil tank, the temperature of the oil returned to the oil tank is detected by a temperature measuring device installed inside the oil tank. Oil that meets the required standard is then transported again.

[0004] In the existing technology, the oil that has passed through the lubrication parts of the equipment is returned to the oil tank. Then, the temperature of the returned oil is measured by a temperature measuring device installed inside the oil tank. However, the temperature measuring device is immersed in the oil for a long time, which easily causes an oil film to form on the surface of the temperature measuring device. In addition, impurities remaining in the oil adhere to the surface of the temperature measuring device, making the measured temperature inaccurate. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a temperature measuring device for a thin oil station lubrication system to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a temperature measuring device for a thin oil station lubrication system, comprising a main body shell, a blocking mechanism disposed on the inner side of the main body shell, and a temperature measuring mechanism disposed below the blocking mechanism. The temperature measuring mechanism includes a sliding frame, a first one-way gear, a limiting post, a first threaded rod, a second one-way gear, a fixing plate, a telescopic post, a cleaning mechanism, and a flow limiting plate. The sliding frame is disposed below the blocking mechanism, the first one-way gear is disposed on one side of the sliding frame, and the limiting post is disposed on one side of the first one-way gear. The first threaded rod is disposed on the inner side of the first one-way gear and extends to the outer side of the sliding frame. The second one-way gear is disposed at the end of the first threaded rod, and the fixing plate is disposed on the outer side of the first threaded rod. The telescopic post is disposed on the inner side of the fixing plate, and the cleaning mechanism is disposed on the inner side of the sliding frame. The flow limiting plate is disposed at the end of the cleaning mechanism, and the temperature measuring mechanism is disposed at the end of the cleaning mechanism. An oil outlet mechanism is disposed on the outer side of the main body shell.

[0007] By adopting the above technical solution, when the sliding frame moves upward with the blocking mechanism, the teeth of the first one-way gear mesh with the inner wall groove of the main body shell, ensuring that the first one-way gear rotates. The first one-way gear causes the limiting post and the first threaded rod to rotate. The threaded connection between the sliding frame and the first threaded rod ensures that when the first threaded rod rotates, the sliding frame moves horizontally along the first threaded rod. When the sliding frame moves horizontally, the cleaning mechanism moves horizontally with the sliding frame, and the cleaning mechanism and the temperature measuring mechanism are in close contact. When the cleaning mechanism moves horizontally, it ensures the cleaning of the surface of the temperature measuring mechanism.

[0008] The present invention is further configured such that the blocking mechanism includes a blocking plate and a limiting toothed plate, the blocking plate is disposed inside the main body shell, the blocking plate has a through groove in the middle, and the bottom of the blocking plate has two sets of toothed plates, and the limiting toothed plate is disposed above the blocking plate.

[0009] By adopting the above technical solution, the through groove set in the middle of the blocking plate ensures that the oil inside the main body shell is the same at the top and bottom when the sliding frame moves horizontally, thus ensuring the vertical flow of the oil. The two sets of racks set at the bottom of the blocking plate ensure that the cleaning mechanism meshes with the racks at the bottom of the blocking plate when the cleaning mechanism moves horizontally with the sliding frame, thus ensuring that the cleaning mechanism rotates when it moves horizontally.

[0010] The present invention is further configured such that a sliding groove is provided on the outer side of the main body shell, and the upper half of the inner side of a set of sliding grooves provided on the outer side of the main body shell is provided with teeth, and the lower half of the inner side of another set of sliding grooves provided on the outer side of the main body shell is provided with teeth.

[0011] By adopting the above technical solution, the teeth provided in the outer sliding groove of the main body shell ensure that when the sliding frame moves upward, the first one-way gear meshes with the teeth in the upper half of the main body shell, ensuring that the first one-way gear rotates. The lower half of the inner side of another set of sliding grooves provided on the outer side of the main body shell is provided with teeth. When the sliding frame moves downward, the second one-way gear meshes with the teeth in the sliding groove of the main body shell, ensuring that the second one-way gear rotates.

[0012] The present invention is further configured such that the cleaning mechanism includes three sets of gears, a threaded sleeve, a second threaded rod, and a cleaning plate, wherein the three sets of gears are disposed inside the sliding frame, the threaded sleeve is disposed on one side of the gears, the second threaded rod is disposed inside the threaded sleeve, and the cleaning plate is disposed at the end of the second threaded rod.

[0013] By adopting the above technical solution, when the sliding frame moves horizontally, the gear moves horizontally. Through the meshing of the gear with the bottom toothed plate of the blocking plate, the gear rotates, thereby causing the threaded sleeve to rotate. Through the threaded connection between the threaded sleeve and the second threaded rod, the second threaded rod pushes the cleaning plate forward, ensuring the cleaning of the temperature measuring mechanism surface when the cleaning plate moves horizontally.

[0014] The present invention is further configured such that the sliding frame is provided with a groove at the top of the blocking plate, and the depth of the groove at the top of the sliding frame is greater than the height of the two sets of teeth at the bottom of the blocking plate, and the bottom teeth of the blocking plate are meshed with the gear.

[0015] By adopting the above technical solution, when the sliding frame moves horizontally, the groove set at the top of the sliding frame ensures that it will not limit the toothed plate set at the bottom of the blocking plate, thus ensuring the meshing connection between the blocking plate and the gear.

[0016] The invention is further configured such that the cleaning plate is U-shaped, and the inner walls on both sides of the cleaning plate are tightly fitted with the temperature measuring mechanism. The cleaning plate and the flow limiting plate are slidably installed, and the flow limiting plate and the temperature measuring mechanism are connected by a sliding groove.

[0017] By adopting the above technical solution, through the "U"-shaped setting of the cleaning plate and the tight fit between the cleaning plate and the temperature measuring mechanism, it is ensured that when the cleaning plate moves horizontally with the sliding frame, it cleans both sides of the temperature measuring mechanism. When the cleaning plate is pulled by the second threaded rod, it causes the cleaning plate to slide outward, ensuring the sealing of the through groove in the middle of the blocking mechanism and ensuring the separation of the oil inside the main body shell.

[0018] The present invention is further configured such that an oil outlet mechanism is provided on the outer side of the main body shell, and the oil outlet mechanism includes an oil outlet pipe, a filter mechanism, a scraping mechanism and an oil pump. The oil outlet pipe is located on the outer side of the main body shell and extends to the inner side of the main body shell. The filter mechanism is located at the end of the oil outlet pipe and has a groove in the middle. The scraping mechanism is located in the groove of the filter mechanism and the oil pump is located on the outer side of the oil outlet pipe.

[0019] By adopting the above technical solution, the oil pump is started, and the oil flows from inside the main body shell through the filter mechanism to the oil outlet pipe. The filter mechanism ensures that the oil inside the main body shell is filtered, and that oil with impurities is not transported into the device.

[0020] The present invention is further configured such that the filtration mechanism includes a limiting tube, a filter plate and a spring telescopic column, wherein the limiting tube is disposed at the end of the oil outlet pipe, the filter plate is disposed inside the limiting tube and the outer side of the filter plate is in contact with the inner wall of the limiting tube, the cleaning block is disposed at the end of the oil outlet pipe and the end of the spring telescopic column is fixedly connected to the filter plate.

[0021] By adopting the above technical solution, after a long period of use, when certain impurities remain on the surface of the filter plate, and the blocking plate does not move upward due to the pressure of the oil, the oil throughput of the filter plate decreases. At this time, the filter plate is squeezed by the oil, causing it to move along the inner wall of the limiting tube. Then, the filter plate is reset by the spring telescopic column. This reciprocating motion ensures that the surface of the filter plate is initially cleaned.

[0022] The present invention is further configured such that the scraping mechanism includes a toothed ring and a cleaning block, the toothed ring is disposed in the groove of the filtering mechanism, the cleaning block is disposed on the inner side of the toothed ring, and the toothed ring and the limiting toothed plate are meshed together.

[0023] By adopting the above technical solution, when the blocking plate moves upward, the limiting tooth plate moves upward. Through the meshing connection between the limiting tooth plate and the toothed ring, the toothed ring and the limiting tube rotate. When the toothed ring rotates, it ensures that the cleaning block rotates, thereby cleaning the surface of the filter plate and ensuring that the filter plate is not clogged due to the accumulation of impurities.

[0024] In summary, the present invention has the following main beneficial effects: This invention comprises a main shell, a blocking mechanism, and a temperature measuring mechanism. When the returning oil accumulates in the lower half of the main shell, the oil level rises, pressing upward against the blocking plate. This causes the blocking plate and the sliding frame to move upward. When the sliding frame continues to move upward to the upper half of the main shell, the first one-way gear meshes with the rack in the groove on the inner wall of the main shell. This causes the first one-way gear to drive the limiting post and the first threaded rod to rotate. Through the threaded connection between the first threaded rod and the sliding frame, the sliding frame moves horizontally along the first one-way gear. As the sliding frame moves horizontally, it drives the gear to move horizontally, causing the gear to mesh with the bottom toothed plate of the blocking mechanism. This causes the gear to drive the threaded sleeve. The rotation of the rod causes the second threaded rod to push the cleaning plate towards the temperature measuring mechanism, causing the flow-limiting plate to retract into the temperature measuring mechanism and creating a gap between the sliding frame and the temperature measuring mechanism. This ensures that the oil flows upward. When the sliding frame moves horizontally, the gear moves horizontally, causing the cleaning plate to move horizontally while adhering to the temperature measuring mechanism. This achieves the purpose of cleaning the surface of the temperature measuring mechanism. When the temperature measuring mechanism moves upward due to the oil, it engages with the inner groove of the main body shell through the second one-way gear, causing the sliding frame to reset. This forces the oil on the outside of the temperature measuring mechanism into the inside of the main body shell, separating the temperature measuring mechanism from the oil and improving the service life of the temperature measuring mechanism.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of the present invention will now be described. Example 1

[0030] A temperature measuring device for a thin oil station lubrication system, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the device includes a main body shell 1. A blocking mechanism 2 is located inside the main body shell 1, and a temperature measuring mechanism 3 is located below the blocking mechanism 2. The temperature measuring mechanism 3 includes a sliding frame 301, a first one-way gear 302, a limiting post 303, a first threaded rod 304, a second one-way gear 305, a fixing plate 306, a telescopic post 307, a cleaning mechanism 308, and a flow-limiting plate 309. The sliding frame 301 is located below the blocking mechanism 2. The first one-way gear 302 is located on one side of the sliding frame 301, and the limiting post 303 is located on one side of the first one-way gear 302. The first threaded rod 304 is located inside the first one-way gear 302 and extends to the outside of the sliding frame 301. When the sliding frame 301 moves upward with the blocking mechanism 2, the teeth of the first one-way gear 302 mesh with the groove on the inner wall of the main body shell 1, ensuring that the first one-way gear 302 rotates. The gear 302 causes the limiting post 303 and the first threaded rod 304 to rotate. Through the threaded connection between the sliding frame 301 and the first threaded rod 304, it is ensured that when the first threaded rod 304 rotates, the sliding frame 301 moves horizontally along the first threaded rod 304. The second one-way gear 305 is located at the end of the first threaded rod 304, and the fixing plate 306 is located on the outside of the first threaded rod 304. The telescopic post 307 is located on the inside of the fixing plate 306, and the cleaning mechanism 308 is located on the inside of the sliding frame 301. The flow limiting plate 309 is located at the end of the cleaning mechanism 308, and the temperature measuring mechanism 310 is located at the end of the cleaning mechanism 308. When the sliding frame 301 moves horizontally, the cleaning mechanism 308 moves horizontally with the sliding frame 301, and the cleaning mechanism 308 and the temperature measuring mechanism 310 are in close contact. When the cleaning mechanism 308 moves horizontally, it ensures the cleaning of the surface of the temperature measuring mechanism 310.

[0031] Please see Figure 2 and Figure 3 The blocking mechanism 2 includes a blocking plate 201 and a limiting toothed plate 202. The blocking plate 201 is located inside the main body shell 1. A through groove is provided in the middle of the blocking plate 201. The through groove in the middle of the blocking plate 201 ensures that when the sliding frame 301 moves horizontally, the oil inside the main body shell 1 is the same at the top and bottom, ensuring the vertical flow of the oil. Two sets of racks are provided at the bottom of the blocking plate 201. The two sets of racks at the bottom of the blocking plate 201 ensure that when the cleaning mechanism 308 moves horizontally with the sliding frame 301, the cleaning mechanism 308 meshes with the racks at the bottom of the blocking plate 201, ensuring that the cleaning mechanism 308 rotates when it moves horizontally. The limiting toothed plate 202 is located above the blocking plate 201.

[0032] Please see Figure 1 , Figure 2 and Figure 8 The outer side of the main body shell 1 is provided with a sliding groove, and the upper half of the inner side of a set of sliding grooves on the outer side of the main body shell 1 is provided with teeth. The teeth provided in the sliding grooves on the outer side of the main body shell 1 ensure that when the sliding frame 301 moves upward, the first one-way gear 302 meshes with the teeth in the upper half of the main body shell 1, ensuring that the first one-way gear 302 rotates. The lower half of the inner side of another set of sliding grooves on the outer side of the main body shell 1 is provided with teeth. The teeth provided in the lower half of the inner side of another set of sliding grooves on the outer side of the main body shell 1 ensure that when the sliding frame 301 moves downward, the second one-way gear 305 meshes with the teeth in the sliding groove of the main body shell 1, ensuring that the second one-way gear 305 rotates.

[0033] Please see Figure 4 , Figure 5 , Figure 6 ,and Figure 7 The cleaning mechanism 308 includes three sets of gears 3081, a threaded sleeve 3082, a second threaded rod 3083, and a cleaning plate 3084. The three sets of gears 3081 are disposed inside the sliding frame 301, the threaded sleeve 3082 is disposed on one side of the gears 3081, the second threaded rod 3083 is disposed inside the threaded sleeve 3082, and the cleaning plate 3084 is disposed at the end of the second threaded rod 3083. When the sliding frame 301 moves horizontally, the gears 3081 move horizontally. Through the meshing of the gears 3081 with the bottom toothed plate of the blocking plate 201, the gears 3081 rotate, thereby causing the threaded sleeve 3082 to rotate. Through the threaded connection between the threaded sleeve 3082 and the second threaded rod 3083, the second threaded rod 3083 pushes the cleaning plate 3084 forward, ensuring the cleaning of the surface of the temperature measuring mechanism 310 when the cleaning plate 3084 moves horizontally.

[0034] Please see Figure 4 and Figure 5 The sliding frame 301 has a groove on the top of the blocking plate 201, and the depth of the groove on the top of the sliding frame 301 is greater than the height of the two sets of teeth on the bottom of the blocking plate 201. The bottom toothed plate of the blocking plate 201 is meshed with the gear 3081. When the sliding frame 301 moves horizontally, the groove on the top of the sliding frame 301 ensures that the bottom toothed plate of the blocking plate 201 will not be limited, thus ensuring that the blocking plate 201 and the gear 3081 are meshed.

[0035] Please see Figure 6 and Figure 7The cleaning plate 3084 is U-shaped, and the inner walls on both sides of the cleaning plate 3084 are tightly fitted with the temperature measuring mechanism 310. Through the U-shaped setting of the cleaning plate 3084 and the tight fit between the cleaning plate 3084 and the temperature measuring mechanism 310, it is ensured that the cleaning plate 3084 cleans both sides of the temperature measuring mechanism 310 when it moves horizontally with the sliding frame 301. The cleaning plate 3084 and the flow limiting plate 309 are slidably installed, and the flow limiting plate 309 and the temperature measuring mechanism 310 are connected by a groove. When the cleaning plate 3084 is pulled by the second threaded rod 3083, the cleaning plate 3084 drives the flow limiting plate 309 to slide outward, ensuring the sealing of the through groove in the middle of the blocking mechanism 2 and ensuring the separation of the oil inside the main body shell 1. Example 2

[0036] Please see Figure 1 and Figure 4 This is the second embodiment of the present invention, specifically a further improvement on the oil outlet mechanism 4 in the above-described specific embodiment 1. The oil outlet mechanism 4 is provided on the outer side of the main body shell 1, and the oil outlet mechanism 4 includes an oil outlet pipe 401, a filter mechanism 402, a scraping mechanism 403, and an oil pump 404. The oil outlet pipe 401 is located on the outer side of the main body shell 1 and extends to the inner side of the main body shell 1. The filter mechanism 402 is located at the end of the oil outlet pipe 401, and a groove is provided in the middle of the filter mechanism 402. The scraping mechanism 403 is located in the groove of the filter mechanism 402, and the oil pump 404 is located on the outer side of the oil outlet pipe 401. By starting the oil pump 404, the oil flows from the inside of the main body shell 1 through the filter mechanism 402 to the oil outlet pipe 401. The filter mechanism 402 ensures that the oil inside the main body shell 1 is filtered, ensuring that oil with impurities is not transported into the device.

[0037] Please see Figure 1 and Figure 8 The filtration mechanism 402 includes a limiting tube 4021, a filter plate 4022, and a spring telescopic column 4023. The limiting tube 4021 is located at the end of the oil outlet pipe 401. The filter plate 4022 is located inside the limiting tube 4021, and the outer side of the filter plate 4022 is in contact with the inner wall of the limiting tube 4021. The cleaning block 4032 is located at the end of the oil outlet pipe 401, and the end of the spring telescopic column 4023 is fixedly connected to the filter plate 4022. When long-term... After use, when certain impurities remain on the surface of the filter plate 4022, and the blocking plate 201 does not move upward due to the pressure of the oil, the oil throughput of the filter plate 4022 decreases. At this time, the filter plate 4022 is squeezed by the oil, causing it to move along the inner wall of the limiting tube 4021. Then, the filter plate 4022 is reset by the spring telescopic column 4023. This reciprocating motion ensures that the surface of the filter plate 4022 is initially cleaned.

[0038] Please see Figure 8 and Figure 9 The scraping mechanism 403 includes a toothed ring 4031 and a cleaning block 4032. The toothed ring 4031 is disposed in the groove of the filter mechanism 402, and the cleaning block 4032 is disposed inside the toothed ring 4031. The toothed ring 4031 is engaged with the limiting toothed plate 202. When the blocking plate 201 moves upward, the limiting toothed plate 202 moves upward. Through the engagement between the limiting toothed plate 202 and the toothed ring 4031, the toothed ring 4031 and the limiting tube 4021 rotate. When the toothed ring 4031 rotates, the cleaning block 4032 rotates, thereby cleaning the surface of the filter plate 4022 and ensuring that the filter plate 4022 is not clogged due to the accumulation of impurities.

[0039] The working principle of this invention is as follows: When the thin oil station is started, the oil pump 404 first starts, causing the oil inside the main body shell 1 to be transported to the processing device through the oil outlet pipe 401 for lubrication. When the oil inside the main body shell 1 passes through the filter plate 4022, it is filtered and then transported out through the main body shell 1. While the oil in the upper part of the main body shell 1 continues to be output, the oil return mechanism 5 returns the oil to the lower part of the main body shell 1. As the oil in the lower part of the main body shell 1 increases, the compression of the oil causes the blocking mechanism 2 and the temperature measuring mechanism 3 to move upward. After the sliding frame 301 moves upward a certain distance, the first one-way gear 302 meshes with the teeth inside the sliding groove on one side of the main body shell 1. This causes the first one-way gear 302 to rotate clockwise, thereby driving the limiting post 303 to rotate clockwise. The limiting post 303 then causes the first threaded rod 304 to rotate. At this time, the threaded connection between the threaded groove in the middle of the sliding frame 301 and the first threaded rod 304 causes the sliding frame 301 to move horizontally. When the sliding frame 301 moves horizontally, the gear 3081 moves horizontally. Through the meshing connection between the gear 3081 and the rack at the bottom of the blocking plate 201, the gear 3081 rotates, thereby driving the threaded sleeve rod 3082 to rotate. Through the threaded connection between the threaded sleeve rod 3082 and the second threaded rod 3083, the second threaded rod 3083 pushes the cleaning plate 3084 towards the temperature measuring mechanism 310. As the cleaning plate 3084 moves toward the temperature measuring mechanism 310, it simultaneously pushes the flow-limiting plate 309 toward the internal groove of the temperature measuring mechanism 310, so that the flow-limiting plate 309 is inside the groove of the temperature measuring mechanism 310. At this time, the oil in the lower half of the main body shell 1 flows through the middle groove of the blocking plate 201 to the upper half of the main body shell 1. As the blocking plate 201 opens, the hydraulic pressure difference between the upper and lower parts of the main body shell 1 gradually becomes equal. As the blocking plate 201 continues to move upward, the limiting toothed plate 202 and the toothed ring 4031 form a meshing connection, causing the toothed ring 4031 to drive the cleaning block 4032 to rotate. The cleaning block 4032 cleans the surface of the filter plate 4022. Wiping cleans the impurities filtered from the surface of the filter plate 4022. As the oil in the upper part of the main body shell 1 continues to increase, the blocking mechanism 2 and the temperature measuring mechanism 3 move downwards. When the temperature measuring mechanism 3 moves to the lower part of the main body shell 1, the second one-way gear 305 meshes with the teeth on the inner wall of the slide groove on the other side of the main body shell 1, causing the second one-way gear 305 to rotate counterclockwise. This causes the first threaded rod 304 to rotate counterclockwise. Through the threaded connection between the first threaded rod 304 and the sliding frame 301, the sliding frame 301 moves in the opposite direction. Through the meshing connection between the gear 3081 and the rack at the bottom of the blocking plate 201, the gear 3081 rotates in the opposite direction, causing the second threaded rod 3083 to pull the cleaning plate 3084.The cleaning plate 3084 pulls the flow-limiting plate 309 outward along the groove of the temperature measuring mechanism 310, thereby sealing the through groove of the blocking mechanism 2. This ensures that the oil in the lower half of the main body shell 1 is not transported to the upper half of the main body shell 1. At this time, the oil return mechanism 5 continuously returns the oil to the inner wall of the main body shell 1. The temperature measuring mechanism 310 measures the temperature of the returned oil. If the oil temperature does not reach the standard, the temperature measuring mechanism 310 controls the cooling device to adjust the temperature of the oil in the lower half of the main body shell 1, thus completing the oil lubrication system.
