Description

Technical Field

[0001] This utility model relates to the field of oil testing technology, and in particular to an oil testing sample oscillation and mixing homogenizer. Background Technology

[0002] In industrial production and equipment operation and maintenance, oil testing is a key link in ensuring safe equipment operation, preventing malfunctions, and controlling environmental pollution. By testing indicators such as oil viscosity, moisture content, and impurity content, we can promptly grasp the oil deterioration status and avoid equipment wear, increased energy consumption, or even safety accidents caused by oil performance degradation. At the same time, it provides a scientific basis for oil replacement and maintenance, which is of great significance for extending equipment life and reducing operation and maintenance costs. In the process of oil testing, the oil sample and reagents must be thoroughly mixed first. The shaking mixing device is the core equipment to achieve this process, and its mixing effect directly affects the accuracy of the test data.

[0003] However, this oil sample oscillation mixer has the following drawbacks:

[0004] (1) Most of the mixing homogenizers on the market use a cam structure to drive the test tube to oscillate. However, this method is prone to causing the test tube to make hard contact with the collision object inside the device, resulting in test tube breakage or sample leakage, which affects the detection process. In addition, some devices can only oscillate a single test tube, which cannot meet the needs of simultaneous detection of multiple sets of samples, greatly reducing the detection efficiency.

[0005] (2) When fixing oil test samples, the existing device requires bolts and arc-shaped clamps to install the test tubes in the designated area. During the disassembly and assembly process, the bolts need to be tightened repeatedly, which is not only cumbersome to operate, but also has the problem of low disassembly and assembly efficiency. Especially in the case of batch sample testing, it seriously restricts the overall testing progress. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] The technical problem solved by the utility model is to provide a highly practical oil sample oscillation and mixing homogenizer that can be operated simply and has a relatively simple structure. This solves the problems mentioned in the background art, such as the test tube easily making hard contact with objects inside the device, leading to test tube damage or sample leakage, as well as the cumbersome operation and low disassembly and assembly efficiency.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: an oil sample oscillation and mixing homogenizer, comprising a base, a test tank fixedly connected to the top of the base, a base plate fixedly connected to the bottom of the inner wall of the test tank, a limiting plate provided inside the test tank and above the base plate, an oscillation assembly for mixing the oil sample provided at the top of the base plate, and a clamping assembly for fixing the oil sample provided inside the limiting plate.

[0010] The oscillation assembly includes a shelf plate disposed inside the base plate and located between the limiting plate and the base plate. Three rollers are rotatably mounted on the bottom of the shelf plate. An annular slide rail is provided inside the base plate to cooperate with the rollers. The rollers are rotatably connected to the inner wall of the annular slide rail. Protrusions are fixedly connected at equal intervals to the inner wall of the annular slide rail. The limiting plate is fixedly mounted above the shelf plate. Insertion holes are provided at equal intervals inside the limiting plate. A telescopic sleeve is fixedly connected to the bottom of the shelf plate. A rotating rod is slidably connected inside the telescopic sleeve. A driven gear is fixedly connected to the outer periphery of the rotating rod.

[0011] The clamping assembly includes an annular airbag fixedly connected to the inner wall of the socket. A fixed cylinder is fixedly connected to the center of the limiting plate. A small air pump is fixedly installed at the bottom of the limiting plate. The output end of the small air pump extends into the interior of the fixed cylinder. Air supply pipes are fixedly connected at equal intervals to the outer periphery of the fixed cylinder. The ends of the air supply pipes away from the fixed cylinder all extend into the interior of the corresponding annular airbag.

[0012] Optionally, a first servo motor is fixedly installed inside the base plate, and a drive gear is fixedly connected to the output shaft of the first servo motor. The rotation of the output shaft of the first servo motor can drive the drive gear to rotate.

[0013] Optionally, the shelf has several circular grooves inside, and the driving gear meshes with the driven gear, which makes the reagent bottle more stable when placed.

[0014] Optionally, both sides of the rotating rod are fixedly connected with flat keys, and the inner wall of the telescopic sleeve is provided with a keyway that cooperates with the flat keys, so that the base plate can drive the shelf to rotate, and at the same time, the shelf can be easily shaken up and down.

[0015] Optionally, the inner wall of each annular airbag is fixedly connected with an anti-slip layer to increase the friction with the reagent bottle, and the reagent bottle is held inside the annular airbag.

[0016] Optionally, the outer periphery of the testing container is provided with a viewing window, which allows the operator to observe the reagent mixing status in real time. The mouth of the reagent bottle is plugged with a stopper.

[0017] (III) Beneficial Effects

[0018] This invention provides an oil sample oscillation and mixing homogenizer, which has the following advantages:

[0019] 1. This oil sample oscillation mixer, through the setting of the oscillation component, can drive the drive gear to rotate, which in turn drives the driven gear and the rotating rod to rotate. The rotating rod drives the telescopic sleeve and the shelf plate to rotate through the cooperation of the flat key and the keyway. The roller at the bottom of the shelf plate rolls along the annular slide rail, which causes the roller to generate intermittent bumps when passing the protrusion. This can drive the reagent bottles on the shelf plate and the limiting plate to oscillate smoothly. The above structure avoids the hard collision of traditional cam drive, reducing the risk of reagent bottle breakage and sample leakage. At the same time, the multiple holes equally spaced on the limiting plate can simultaneously place multiple sets of reagent bottles to meet the needs of batch testing.

[0020] 2. This oil sample oscillation and mixing homogenizer, through the clamping assembly, allows airflow to be injected into the annular air bladder via a fixed cylinder and air supply tube. After the air bladder inflates, it tightly wraps around the outer wall of the reagent bottle, thus securing it. During disassembly, only a small air pump needs to be controlled to absorb the gas inside the air bladder to remove the reagent bottle. No bolts need to be tightened throughout the process, significantly improving the efficiency of batch sample processing. In addition, the anti-slip layer on the inner wall of the annular air bladder increases the friction with the reagent bottle, preventing the reagent bottle from shifting during oscillation. At the same time, the flexible clamping of the air bladder can adapt to reagent bottles of different diameters, improving the versatility of the device and overcoming the limitation of traditional clamps that can only fix test tubes of a single size.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figures 1 to 4 This utility model provides a technical solution: an oil sample oscillation and mixing homogenizer, including a base 1, a test tank 2 fixedly connected to the top of the base 1, a bottom plate 3 fixedly connected to the bottom of the inner wall of the test tank 2, a limiting plate 8 provided inside the test tank 2 and above the bottom plate 3, an oscillation component for mixing the oil sample provided at the top of the bottom plate 3, and a clamping component for fixing the oil sample provided inside the limiting plate 8.

[0028] The oscillation assembly includes a shelf 7 disposed inside the base plate 3 and located between the limiting plate 8 and the base plate 3. Three rollers 6 are rotatably mounted on the bottom of the shelf 7. An annular slide rail 4, which mates with the rollers 6, is provided inside the base plate 3. The rollers 6 are rotatably connected to the inner wall of the annular slide rail 4. Protrusions 5 are fixedly connected at equal intervals to the inner wall of the annular slide rail 4. The limiting plate 8 is fixedly mounted above the shelf 7. Insertion holes 20 are equidistantly provided inside the limiting plate 8. A telescopic sleeve 15 is fixedly connected to the bottom of the shelf 7. A rotating rod 16 is slidably connected inside the telescopic sleeve 15. A driven gear 9 is fixedly connected to the outer periphery of the rotating rod 16. A first servo motor... 11 drives the active gear 10 to rotate, which in turn drives the driven gear 9 and the rotating rod 16 to rotate. The rotating rod 16 drives the telescopic sleeve 15 and the shelf 7 to rotate through the cooperation of the flat key 17 and the keyway 18. The roller 6 at the bottom of the shelf 7 rolls along the annular slide rail 4, which causes the roller 6 to generate intermittent bumps when passing the protrusion 5. This allows the reagent bottles on the shelf 7 and the limiting plate 8 to oscillate smoothly. The above structure avoids the hard collision of traditional cam drive, reduces the risk of reagent bottle breakage and sample leakage. At the same time, the multiple insertion holes 20 equidistantly opened on the limiting plate 8 can simultaneously place multiple sets of reagent bottles to meet the needs of batch testing.

[0029] The clamping assembly includes an annular airbag 21 fixedly connected to the inner wall of the insertion hole 20, a fixed cylinder 12 fixedly connected to the center of the limiting plate 8, a small air pump 13 fixedly installed at the bottom of the limiting plate 8, the output end of the small air pump 13 extending into the interior of the fixed cylinder 12, and air delivery tubes 22 fixedly connected at equal intervals to the outer periphery of the fixed cylinder 12. The ends of the air delivery tubes 22 away from the fixed cylinder 12 all extend into the interior of the corresponding annular airbag 21. When the reagent bottle is inserted into the insertion hole 20, the small air pump 13 can be activated, and airflow passes through the fixed cylinder 12 and the air delivery tubes. 22 is injected into the annular air bladder 21. After the air bladder expands, it tightly wraps around the outer wall of the reagent bottle, thus fixing it. When disassembling, only the small air pump 13 needs to be controlled to absorb the gas in the air bladder to remove the reagent bottle. No bolts need to be tightened throughout the process, which greatly improves the efficiency of batch sample processing. In addition, the anti-slip layer 19 on the inner wall of the annular air bladder 21 can increase the friction with the reagent bottle and prevent the reagent bottle from shifting during the oscillation process. At the same time, the flexible clamping of the air bladder can adapt to reagent bottles of different diameters, improve the versatility of the device, and solve the limitation of traditional clamps that can only fix a single specification of test tube.

[0030] The base plate 3 has a first servo motor 11 fixedly installed inside. The output shaft of the first servo motor 11 is fixedly connected to a drive gear 10. The drive gear 10 can be driven to rotate by the rotation of the output shaft of the first servo motor 11.

[0031] The shelf 7 has several circular grooves 14 inside. The circular grooves 14 make the reagent bottle more stable when placed. The driving gear 10 is meshed with the driven gear 9.

[0032] Both sides of the rotating rod 16 are fixedly connected with flat keys 17. The inner wall of the telescopic sleeve 15 is provided with a keyway 18 that works with the flat keys 17. Through the cooperation of the flat keys 17 and the keyway 18, the base plate 3 can drive the shelf 7 to rotate, and the shelf 7 can be easily shaken up and down.

[0033] The inner wall of the annular airbag 21 is fixedly connected with an anti-slip layer 19. The anti-slip layer 19 can increase the friction with the reagent bottle. The reagent bottle is held inside the annular airbag 21.

[0034] The outer periphery of the testing container 2 is equipped with a viewing window, which allows operators to observe the reagent mixing status in real time. The mouth of the reagent bottle is plugged with a stopper.

[0035] In this invention, the working steps of the device are as follows:

[0036] First step: After inserting the reagent bottle into the socket 20, the small air pump 13 can be started. The airflow is injected into the annular air bag 21 through the fixed cylinder 12 and the air supply tube 22. After the air bag expands, it tightly wraps around the outer wall of the reagent bottle and completes the fixation. When disassembling, the reagent bottle can be removed by controlling the small air pump 13 to absorb the gas in the air bag. No bolts need to be turned throughout the process, which greatly improves the efficiency of batch sample processing. In addition, the anti-slip layer 19 on the inner wall of the annular air bag 21 can increase the friction with the reagent bottle and prevent the reagent bottle from shifting during the oscillation. At the same time, the flexible clamping of the air bag can adapt to reagent bottles of different diameters, improving the versatility of the device.

[0037] The second step: When the oil sample is oscillating, the first servo motor 11 can be controlled to drive the active gear 10 to rotate, which in turn drives the driven gear 9 and the rotating rod 16 to rotate. The rotating rod 16 drives the telescopic sleeve 15 and the shelf plate 7 to rotate through the cooperation of the flat key 17 and the keyway 18. The roller 6 at the bottom of the shelf plate 7 rolls along the annular slide rail 4, which causes the roller 6 to generate intermittent bumps when passing the protrusion 5. This enables the reagent bottles on the shelf plate 7 and the limiting plate 8 to oscillate smoothly. The above structure avoids the hard collision of traditional cam drive, reduces the risk of reagent bottle breakage and sample leakage. At the same time, the multiple insertion holes 20 equidistantly opened on the limiting plate 8 can simultaneously place multiple sets of reagent bottles to meet the needs of batch testing.
