Description

Technical Field

[0001] This invention relates to the field of lubricating oil testing technology, and in particular to a lubricating oil viscosity testing device with a temperature regulation structure. Background Technology

[0002] The viscosity of lubricating oil is one of its most important physical properties, directly affecting its lubrication effect in mechanical equipment. The main functions of lubricating oil are to reduce friction, prevent wear, dissipate heat, and prevent corrosion. Therefore, testing the viscosity of lubricating oil is crucial.

[0003] The lubricating oil viscosity testing device is mainly used to measure and evaluate the viscosity of lubricating oil, ensuring that the lubricating oil has the best performance under different mechanical equipment and working environments.

[0004] Viscosity testing is a crucial step in the production of lubricating oil because its viscosity changes with temperature, requiring real-time monitoring and adjustment. This necessitates testing at different temperatures. Typically, thickeners are added to the lubricating oil during production to improve its viscosity and adhesion. To ensure the effectiveness and uniform distribution of these thickeners, viscosity testing equipment must not only provide accurate viscosity values ​​but also assess changes after thickener addition, allowing for adjustments to their concentration and distribution.

[0005] During testing, the lubricating oil and thickener need to be stirred. During the stirring and mixing process, air bubbles are easily generated due to the physical interaction between the liquids and the stirring speed. The foam formed by the air bubbles in the lubricating oil will significantly affect the viscosity and other physical properties of the lubricating oil, especially under high temperature or high speed operating conditions. The viscosity test needs to take into account the influence of air bubbles on the measurement results. Reducing air bubble interference can ensure the accuracy of viscosity. In addition, air bubbles may change the flow characteristics and stability of the lubricating oil, leading to oil film rupture and uneven dispersion of thickener, thereby affecting the lubrication effect and the operating efficiency of mechanical equipment. Summary of the Invention

[0006] The purpose of this invention is to solve the problem in the prior art where a large number of bubbles are often generated during the stirring and mixing process due to factors such as the physical interaction between liquids and the stirring speed.

[0013] In the above technical solution, preferably, the four scrapers are movably connected to the outside of the microporous filter plate on opposite sides, and two stirring blades are fixedly installed on both sides of the third rotating rod.

[0017] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this embodiment of the invention, during use, after the lubricating oil and thickener are added to the inner liner and the mixing tank is closed, the operator can start the motor through the power supply system on the base. During operation, the motor drives the main shaft via the output shaft, and the main shaft, through the support, rotates the mixing tank. As the mixing tank rotates, the inner liner rotates via the rotating disc, causing the lubricating oil inside to tumble back and forth. This removes air bubbles generated during the mixing of the lubricating oil and thickener. As the inner liner tumbles the lubricating oil, it passes through a microporous filter plate, which physically intercepts air bubbles in the lubricating oil. When air bubbles flow through the microporous filter plate with the lubricating oil, the bubble film contacts the microporous filter plate, thus removing the bubbles. The structure of the support components and microporous filter plate not only eliminates air bubbles, but also allows the inner liner to rotate, causing the lubricating oil and thickener to tumble inside, promoting the removal of air bubbles from the lubricating oil. This tumbling action effectively removes air bubbles, avoiding their influence. At the same time, the microporous filter plate effectively intercepts and eliminates air bubbles in the lubricating oil. When air bubbles come into contact with the microporous filter plate during the flow of lubricating oil, the bubble film contacts and breaks down. Through this physical interception process, the presence of air bubbles can be further reduced, ensuring that the lubricating oil does not contain too many air bubbles, thereby maintaining its ideal viscosity and stability. This solves the problem in existing technologies where a large number of air bubbles are often generated during the mixing process due to the physical interaction between liquids and the stirring speed, thus improving the accuracy of test results.

[0018] 2. In this embodiment of the invention, during use, when the mixing drum rotates, it drives the second rotating rod to rotate the pinion around the inner ring of the gear ring. As the pinion rotates, the teeth on the inner side of the gear ring cause it to rotate. Simultaneously, the pinion drives the second rotating rod, which in turn drives the first bevel gear to rotate. When the first bevel gear rotates, it drives the rotating disk via the third bevel gear, causing the first ball bearing to roll inside the groove. As the rotating disk rotates, the connecting post, through its engagement with the first connecting groove, causes the inner liner to rotate on the outer surface of the second ball bearing. Furthermore, when the first bevel gear rotates, it drives the first rotating rod to rotate via the second bevel gear. When the first rotating rod rotates, the connecting piece, through its engagement with the second connecting groove, drives the third rotating rod to rotate. When the third rotating rod rotates, it... The stirring blades rotate in a circular motion to mix the lubricating oil and the thickener. Simultaneously, the rotation of the third rotating rod causes the scraper to rotate in a circular motion along the inner wall of the inner tank and both sides of the microporous filter plate. Through the connecting parts and rotating disk structure, the mixing tank rotates, and the gear ring drives the second and third bevel gears. When the second and third bevel gears rotate, the connecting parts and rotating disk cause the stirring blades and the inner tank to rotate in opposite directions. This effectively avoids dead zones during mixing, ensuring a more thorough mixing effect and improving product quality. Furthermore, the opposite rotation allows the stirring blades and the inner tank to interact, generating stronger shearing and impact forces, which helps accelerate the mixing process, saves mixing time, and improves work efficiency. The rotation of the scraper effectively prevents the thickener from adhering to the inner wall of the inner tank and the surface of the microporous filter plate, further increasing the uniformity of the mixture.

[0019] 3. In this embodiment of the invention, during use, the operator can first place the inner liner on top of the mixing tank and press it down so that it can be embedded inside the mixing tank. The inner liner then slides downwards on the outer surface of the second ball bearing, allowing it to adhere to the top of the rotating disc. When the inner liner is in contact with the rotating disc, the connecting post is embedded into the first connecting groove, and the bottom of the connector is embedded into the second connecting groove inside the first rotating rod. This allows the inner liner to connect with the transmission assembly. Afterwards, the operator can add lubricating oil and a tackifier to the inside of the inner liner, then remove the lid and place it on top of the mixing tank, ensuring the sealing gasket... It can be embedded inside the sealing groove, allowing the positioning pin to be embedded in the mixing tank and fit against the top outer surface of the inner liner to prevent lubricating oil leakage when the inner liner rotates. Then, the operator can flip the bolt to embed it between the two fixing plates and turn the nut so that its top fits against the bottom of the fixing plate to fix the lid onto the mixing tank. The design of the sealing gasket and positioning pin structure not only makes it easy for operators to fix the lid onto the mixing tank, saving operation time and complicated assembly processes, but also effectively prevents lubricating oil leakage during rotation, especially during high-speed stirring, ensuring the integrity of the mixture.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-9This embodiment provides a technical solution: a lubricating oil viscosity testing device with a temperature regulating structure, including a base 1, a main shaft 101 movably embedded in the left side of the base 1, a support member 112 fixedly installed on the right side of the main shaft 101, a mixing tank 102 fixedly installed on the right side of the support member 112, and a plurality of second ball bearings 111 disposed inside the mixing tank 102; further including: a motor 113 fixedly installed on the left side of the main shaft 101, the bottom of the motor 113 fixedly installed on the top left side of the base 1; a first rotating rod 103 movably embedded in the bottom side of the inner wall of the mixing tank 102; and a rotating disk 104 movably embedded inside the mixing tank 102. The rotating disc 104 is movably sleeved on the top outer surface of the first rotating rod 103, and a plurality of first balls 109 are provided on the outer side of the rotating disc 104; the inner wall of the mixing tank 102 is provided with a sliding groove 110, and the plurality of first balls 109 are all disposed inside the sliding groove 110; the inner liner 105 is movably connected to the top of the rotating disc 104, and a plurality of connecting posts 106 are fixedly installed at the bottom of the inner liner 105; a plurality of first connecting grooves 107 are provided on the top side of the rotating disc 104, and the plurality of connecting posts 106 are all matched with the first connecting grooves 107; a microporous filter plate 108 is provided inside the inner liner 105, and the inner liner 105 is movably connected to the outer surface of a plurality of second balls 111.

[0024] In use, after the lubricating oil and thickener are added into the inner tank 105 and the mixing tank 102 is closed, the operator can start the motor 113 via the power supply system on the base 1. During operation, the motor 113 drives the main shaft 101 through the output shaft, and the main shaft 101 drives the mixing tank 102 to rotate via the support member 112. When the mixing tank 102 rotates, the inner tank 105 rotates via the rotating disk 104. This, in turn, causes the lubricating oil inside the inner tank 105 to tumble back and forth, removing air bubbles generated during the mixing of the lubricating oil and thickener. As the inner tank 105 tumbles the lubricating oil, it passes through the microporous filter plate 108, which physically intercepts air bubbles in the lubricating oil. When the lubricating oil flows through the microporous filter plate 108, the bubble membrane comes into contact with the microporous filter plate 108, thereby eliminating the bubbles. Furthermore, the structure of the support member 112 and the microporous filter plate 108 allows the inner liner 105 to rotate, causing the lubricating oil and thickener to tumble inside, promoting the removal of bubbles from the lubricating oil. This tumbling action effectively removes bubbles, avoiding their influence. Simultaneously, the microporous filter plate 108 effectively intercepts and eliminates bubbles in the lubricating oil. When bubbles come into contact with the microporous filter plate 108 during the lubricating oil flow, the bubble membrane contacts and breaks down. This physical interception process further reduces the presence of bubbles, ensuring that the lubricating oil does not contain excessive bubbles, thus maintaining its ideal viscosity and stability.

[0025] Please see Figures 1 to 9 In one embodiment, a gear ring 2 is fixedly installed on the right side of the base 1, and a second rotating rod 201 is movably embedded in the left side of the inside of the mixing barrel 102. A pinion 202 is fixedly installed on the left side of the second rotating rod 201. The pinion 202 meshes with the gear ring 2, so the mixing barrel 102 can drive the second rotating rod 201 to drive the pinion 202 to rotate around the inner ring of the gear ring 2. When the pinion 202 rotates around the ring, the teeth on the inner side of the gear ring 2 can be used to rotate the pinion 202.

[0026] Please see Figures 1 to 9 In one embodiment, a first bevel gear 203 is fixedly installed on the right side of the second rotating rod 201, and a second bevel gear 204 is fixedly sleeved on the outer surface of the first rotating rod 103. The second bevel gear 204 meshes with the adjacent first bevel gear 203, so that it can be transmitted to the second rotating rod 201 through the pinion 202, and the second rotating rod 201 drives the first bevel gear 203 to rotate.

[0027] Please see Figures 1 to 9In one embodiment, a third bevel gear 205 is fixedly sleeved on the bottom outer surface of the rotating disk 104. The third bevel gear 205 meshes with the adjacent first bevel gear 203. A connector 206 is movably embedded in the bottom side of the inner liner 105. A second connecting groove 207 is opened on the top side of the inner side of the first rotating rod 103. So when the rotating disk 104 rotates, the inner liner 105 can be driven to rotate on the outer surface of the second ball bearing 111 through the cooperation of the connecting post 106 and the first connecting groove 107.

[0028] Please see Figures 1 to 9 In one embodiment, the bottom outer surface of the connector 206 is movably embedded inside the second connecting groove 207, and the top of the connector 206 is fixedly mounted with a third rotating rod 208. When the first bevel gear 203 rotates, it will drive the first rotating rod 103 to rotate through the second bevel gear 204. When the first rotating rod 103 rotates, the third rotating rod 208 can be driven to rotate through the cooperation between the connector 206 and the second connecting groove 207.

[0029] Please see Figures 1 to 9 In one embodiment, two scrapers 210 are fixedly installed on both sides of the third rotating rod 208, and all four scrapers 210 are movably connected to the inner surface of the inner liner 105. When the third rotating rod 208 rotates, it will synchronously drive the scrapers 210 to rotate around the inner wall of the inner liner 105 and the two sides of the microporous filter plate 108.

[0030] Please see Figures 1 to 9 In one embodiment, the four scrapers 210 are movably connected to the outer side of the microporous filter plate 108 on opposite sides, and two stirring blades 209 are fixedly installed on both sides of the third rotating rod 208. When the third rotating rod 208 rotates, it can drive the stirring blades 209 to rotate in a circle to mix and stir the lubricating oil and the thickener.

[0031] Please see Figures 1 to 9 In one embodiment, a lid 301 is movably fitted on the top of the mixing tank 102, and a sealing gasket 3 is provided on the top of the inner liner 105. A sealing groove 302 is provided on the top side of the inner wall of the lid 301, so that the lid 301 can be lifted and placed on the top of the mixing tank 102, and the sealing gasket 3 can be embedded in the interior of the sealing groove 302.

[0032] Please see Figures 1 to 9In one embodiment, the sealing gasket 3 is movably embedded inside the sealing groove 302, and positioning posts 303 are fixedly installed on both sides of the bottom of the bucket lid 301. Both positioning posts 303 are movably connected to the top outer surface of the inner liner 105. Multiple bolts 304 are movably embedded inside the bucket lid 301, so that the positioning posts 303 can be embedded into the mixing bucket 102 and fit against the top outer surface of the inner liner 105.

[0033] Please see Figures 1 to 9 In one embodiment, nuts 306 are threaded onto the outer surfaces of multiple bolts 304. Multiple fixing plates 305 are fixedly installed on the outer surface of the mixing tank 102. The multiple bolts 304 are movably embedded inside the fixing plates 305, and the tops of the multiple nuts 306 are movably connected to the bottom of the fixing plates 305. The bolts 304 can be rotated to embed themselves between two fixing plates 305, and the nuts 306 can be rotated so that their tops fit against the bottom of the fixing plates 305, thereby fixing the tank lid 301. An automatic telescopic rod 307 is installed at the center of one side of the base 1 on the mixing tank 102. An installation plate 308 is fixedly installed at the output end of the automatic telescopic rod 307. A heating plate 309 is installed on one side of the installation plate 308. When the internal temperature of the mixing tank 102 is too low, the automatic telescopic rod 307 is controlled to drive the installation plate 308 to move upward, so that the heating plate 309 and the bottom of the mixing tank 102 come into contact. At this time, the heating plate 309 heats the mixing tank 102 and adjusts the temperature, which is convenient for testing at different temperatures.

[0034] Working principle: During use, after the lubricating oil and thickener are added into the inner tank 105 and the mixing tank 102 is closed, the operator can start the motor 113 via the power supply system on the base 1. During operation, the motor 113 drives the main shaft 101 through the output shaft, and the main shaft 101 drives the mixing tank 102 to rotate via the support member 112. When the mixing tank 102 rotates, it drives the inner tank 105 to rotate via the rotating disk 104. This, in turn, causes the lubricating oil inside the inner tank 105 to tumble back and forth, removing air bubbles generated during the mixing of the lubricating oil and thickener. As the inner tank 105 tumbles the lubricating oil, it passes back and forth through the microporous filter plate 108, further facilitating the removal of air bubbles. The microporous filter plate 108 can physically intercept air bubbles in the lubricating oil. When air bubbles flow through the microporous filter plate 108 with the lubricating oil, the bubble membrane comes into contact with the microporous filter plate 108, thereby eliminating the air bubbles. Furthermore, the structure of the support member 112 and the microporous filter plate 108 not only allows the inner liner 105 to rotate, causing the lubricating oil and thickener to tumble inside, promoting the removal of air bubbles from the lubricating oil, but also effectively removes air bubbles, avoiding their impact. Simultaneously, the microporous filter plate 108 effectively intercepts and eliminates air bubbles in the lubricating oil. When air bubbles come into contact with the microporous filter plate 108 during the lubricating oil flow, the bubble membrane comes into contact with and is broken by the microporous filter plate 108. This physical interception process further reduces the presence of air bubbles, ensuring that the lubricating oil does not contain excessive air bubbles. At this point, the lubricating oil can be tested to maintain its ideal viscosity and stability. During use, when the mixing tank 102 rotates, it drives the second rotating rod 201 to rotate the pinion 202 around the inner ring of the gear ring 2. As the pinion 202 rotates, the teeth on the inner side of the gear ring 2 rotate it. Simultaneously, the pinion 202 transmits power to the second rotating rod 201, which in turn drives the first bevel gear 203 to rotate. When the first bevel gear 203 rotates, it transmits power to the rotating disk 10 through the third bevel gear 205. 4. The rotating disk 104 drives the first ball bearing 109 to roll inside the sliding groove 110. When the rotating disk 104 rotates, the connecting column 106, in conjunction with the first connecting groove 107, drives the inner liner 105 to rotate on the outer surface of the second ball bearing 111. When the first bevel gear 203 rotates, it transmits power to the first rotating rod 103 via the second bevel gear 204. When the first rotating rod 103 rotates, the connecting piece 206, in conjunction with the second connecting groove 207, drives the third rotating rod 208 to rotate. When the third rotating rod 208 rotates, it drives the stirring blade 209 to rotate in a circle to mix the lubricating oil and the thickener.The scraper 210 will be driven to rotate in a circle around the inner wall of the inner liner 105 and both sides of the microporous filter plate 108. Through the structure of the connecting piece 206 and the rotating disk 104, when the mixing tank 102 rotates, it can be driven by the gear ring 2 to the second bevel gear 204 and the third bevel gear 205. When the second bevel gear 204 and the third bevel gear 205 rotate, the stirring blade 209 can be driven to rotate in the opposite direction to the inner liner 105 through the connecting piece 206 and the rotating disk 104. This effectively avoids dead zones in the mixing process, ensures a more thorough mixing effect, and improves product quality. At the same time, the rotation in the opposite direction allows the stirring blade 209 and the inner liner 105 to interact, generating stronger shearing and impact forces, which helps to accelerate the mixing process, save mixing time, and improve work efficiency. Furthermore, the rotation of the scraper 210 can effectively prevent the thickener from adhering to the inner wall of the inner liner 105 and the surface of the microporous filter plate 108, further increasing the uniformity of mixing. In use, the operator first places the inner liner 105 on top of the mixing tank 102 and presses it down so that it can be embedded inside the mixing tank 102. The inner liner 105 then slides downwards on the outer surface of the second ball bearing 111, allowing it to adhere to the top of the rotating disk 104. When the inner liner 105 is in contact with the rotating disk 104, the connecting post 106 is embedded into the first connecting groove 107, and the bottom of the connecting piece 206 is embedded into the second connecting groove 207 inside the first rotating rod 103. This allows the inner liner 105 to connect with the transmission assembly. Afterwards, the operator adds lubricating oil and a tackifier to the inside of the inner liner 105, then removes the lid 301 and places it on top of the mixing tank 102 to seal it. The gasket 3 can be embedded inside the sealing groove 302, while the positioning post 303 can be embedded into the mixing tank 102 and fit against the top outer surface of the inner liner 105, preventing lubricating oil leakage when the inner liner 105 rotates. Then, the operator can flip the bolt 304 so that it can be embedded between the two fixing plates 305, and rotate the nut 306 so that its top fits against the bottom of the fixing plate 305, thus fixing the lid 301 onto the mixing tank 102. The structure of the sealing gasket 3 and the positioning post 303 not only facilitates fixing the lid 301 onto the mixing tank 102, saving operation time and complex assembly processes, but also effectively prevents lubricating oil leakage during rotation, especially during high-speed mixing, ensuring the integrity of the mixture.
