Description

Technical Field

[0001] This utility model relates to the field of refrigeration oil production technology, and in particular to a device for uniformly mixing and stirring refrigeration oil additives. Background Technology

[0002] Refrigeration oil, also known as refrigeration compressor oil or refrigeration lubricating oil, is a type of lubricating oil used in refrigeration compressors. Its main function is to reduce friction and wear during compressor operation, thereby extending the service life of the equipment.

[0003] In existing technologies, in order to improve the lubrication performance, oxidation resistance, and corrosion resistance of refrigeration oil, and thus meet the operating requirements of refrigeration compressors in harsh environments such as low temperature and high pressure, it is necessary to add additives to the refrigeration oil. However, most existing stirring structures are single-shaft structures. Some equipment is equipped with a reversing function to prevent lubricating oil additives from sticking together, but some high-viscosity additives still cannot be separated by this stirring mode, and the stirring effect is not good enough.

[0004] In response to this technical problem, this application proposes a device for uniformly mixing and stirring refrigeration oil additives. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a uniform mixing and stirring device for refrigeration oil additives. When the second stirring rod rotates, it is pressed downward by the protrusion of the wave ring. When it is in the groove, the elastic force of the first spring can drive the arc-shaped sliding block to reset, thereby causing the second stirring rod to move up and down reciprocally, increasing the stirring effect and enabling the refrigeration oil additives to be mixed uniformly.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A uniform mixing and stirring device for refrigeration oil additives includes a base, a bottom plate slidably connected to the inner wall of the base, support rods fixedly connected to the four corners of the top of the bottom plate, support rings fixedly connected to the top of the support rods, a mixing cylinder fixedly connected to the top of the support rings, a feed pipe fixedly connected to the right end of the mixing cylinder, a discharge valve fixedly connected to the bottom end of the mixing cylinder, a motor fixedly connected to the top of the mixing cylinder, a first stirring rod fixedly connected to the drive end of the motor, an auxiliary stirring assembly provided on the outer wall of the first stirring rod, and buffer and shock absorption assemblies provided on both sides of the inner wall of the bottom end of the base.

[0008] Furthermore, the auxiliary stirring assembly includes a connecting rod fixedly connected to the outer wall of the first stirring rod, a connecting ring fixedly connected to one end of the outer side of the connecting rod, and a second stirring rod slidably connected to the four corners of the inner wall of the connecting ring, with a limit strip provided on the outer wall of the second stirring rod.

[0009] Furthermore, an arc-shaped sliding block is fixedly connected to the top of the second stirring rod, and a wave ring is fixedly connected to the inner wall of the top of the mixing cylinder, the wave ring corresponding to the arc-shaped sliding block.

[0010] Furthermore, a limiting block is fixedly connected to the outer wall of the second stirring rod, and the bottom end of the limiting block is connected to the top end of the connecting ring by a first spring.

[0011] Furthermore, one end of the first spring is connected to the bottom end of the limiting block, and the other end of the first spring is connected to the top end of the connecting ring.

[0012] Furthermore, the buffer and shock absorption assembly includes support blocks fixedly connected to both sides of the inner wall at the bottom of the base, a sliding rod fixedly connected to the inner wall of the support block, sliders slidably connected to both sides of the outer wall of the sliding rod, a rotating rod rotatably connected to the top of the slider, the inner wall of the support block and the outer wall of the slider being connected by a second spring, and a damper fixedly connected between the inner wall of the base and the bottom of the base plate.

[0013] Furthermore, a connecting plate is fixedly connected to the bottom end of the base plate, and the top end of the rotating rod is rotatably connected to the bottom end of the connecting plate.

[0014] Furthermore, one end of the second spring is connected to the inner wall of the support block, and the other end of the second spring is connected to the outer wall of the slider.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when the second stirring rod rotates, it is pressed downward by the protrusion of the wave ring. When it is in the groove, the elastic force of the first spring can drive the arc-shaped sliding block to reset, thereby causing the second stirring rod to move up and down repeatedly, increasing the stirring effect and enabling the refrigeration oil additive to be mixed evenly.

[0017] 2. In this utility model, the second spring acts as a buffer for the slider, while the damper acts as a damper for the base plate to absorb energy and reduce vibration, further buffering and reducing vibration of the mixing drum, preventing the mixing drum from vibrating too much during the mixing process and causing equipment damage.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] Reference Figures 1-2 This utility model provides an embodiment of a uniform mixing and stirring device for refrigeration oil additives, comprising a base 1, a base plate 2 slidably connected to the inner wall of the base 1, support rods 3 fixedly connected to the four corners of the top of the base plate 2, support rings 4 fixedly connected to the top of the support rods 3, a mixing cylinder 5 fixedly connected to the top of the support rings 4, a feed pipe 6 fixedly connected to the right end of the mixing cylinder 5, a discharge valve 16 fixedly connected to the bottom end of the mixing cylinder 5, a motor 7 fixedly connected to the top of the mixing cylinder 5, a first stirring rod 8 fixedly connected to the drive end of the motor 7, a connecting rod 9 fixedly connected to the outer wall of the first stirring rod 8, and a connecting rod 9 on the outer side of the connecting rod 9. A connecting ring 10 is fixedly connected, and a second stirring rod 11 is slidably connected to the four corners of the inner wall of the connecting ring 10. A limit strip is provided on the outer wall of the second stirring rod 11. An arc-shaped sliding block 13 is fixedly connected to the top of the second stirring rod 11. A wave ring 12 is fixedly connected to the inner wall of the top of the mixing cylinder 5. The wave ring 12 corresponds to the arc-shaped sliding block 13. A limit block 14 is fixedly connected to the outer wall of the second stirring rod 11. The bottom end of the limit block 14 is connected to the top of the connecting ring 10 through a first spring 15. One end of the first spring 15 is connected to the bottom end of the limit block 14, and the other end of the first spring 15 is connected to the top of the connecting ring 10.

[0025] Specifically, during operation, the refrigerant oil and additives to be mixed are first injected into the mixing drum 5 through the feed pipe 6. Then, the motor 7 is started, and its drive end rotates the first stirring rod 8, which in turn causes the connecting rod 9 and connecting ring 10 to rotate. The rotation of the connecting ring 10 then drives the second stirring rod 11 to rotate, achieving mixing of the refrigerant oil and additives within the mixing drum 5. Simultaneously, the arc-shaped sliding block 13 at the top of the second stirring rod 11 slides on the inner wall of the wave ring 12. When the arc-shaped sliding block 13 encounters the protruding part of the wave ring 12, it is pressed downwards; when it encounters the groove, the elastic force of the first spring 15 returns the arc-shaped sliding block 13 to its original position, thus causing the second stirring rod 11 to reciprocate up and down, enhancing the mixing effect and ensuring uniform mixing of the refrigerant oil and additives. Furthermore, during the mixing process, the limiting strip on the outer wall of the second stirring rod 11 ensures that the arc-shaped sliding block 13 maintains a constant angle.

[0026] Reference Figure 1 and Figure 3 Support blocks 17 are fixedly connected to both sides of the inner wall of the bottom end of the base 1. A sliding rod 18 is fixedly connected to the inner wall of the support block 17. A slider 19 is slidably connected to both sides of the outer wall of the sliding rod 18. A rotating rod 20 is rotatably connected to the top of the slider 19. The inner wall of the support block 17 and the outer wall of the slider 19 are connected by a second spring 22. A damper 23 is fixedly connected between the inner wall of the base 1 and the bottom end of the base plate 2. A connecting plate 21 is fixedly connected to the bottom end of the base plate 2. The top of the rotating rod 20 is rotatably connected to the bottom end of the connecting plate 21. One end of the second spring 22 is connected to the inner wall of the support block 17, and the other end of the second spring 22 is connected to the outer wall of the slider 19.

[0027] Specifically, during the mixing process, the mixing drum 5 may vibrate. To mitigate this issue, the mixing drum 5, via the support ring 4 and support rod 3, causes the base plate 2 to slide on the inner wall of the base 1. The base plate 2, through the connecting plate 21, drives the rotating rod 20 to rotate, which in turn causes the slider 19 to slide on the outer wall of the slide rod 18. The second spring 22 provides cushioning for the slider 19, while the damper 23 performs damping and shock absorption on the base plate 2, absorbing energy. These mechanisms work together to further provide cushioning and shock absorption for the mixing drum 5, effectively preventing excessive vibration during mixing and thus avoiding equipment damage.

[0028] Working Principle: In operation, the refrigerant oil and additives to be mixed are first poured into the mixing drum 5 through the feed pipe 6. Then, the motor 7 is started, driving the first stirring rod 8 to rotate. The first stirring rod 8 drives the connecting rod 9 and connecting ring 10 to rotate, and the connecting ring 10 drives the second stirring rod 11 to rotate, thus mixing the refrigerant oil and additives in the mixing drum 5. Simultaneously, the arc-shaped sliding block 13 at the top of the second stirring rod 11 slides against the inner wall of the wave ring 12. This causes the second stirring rod 11 to be pressed downwards by the protrusions of the wave ring 12 during rotation, and when in the groove, the elastic force of the first spring 15 can cause the arc-shaped sliding block 13 to return to its original position, thereby causing the second stirring rod 11 to move up and down reciprocally, increasing the mixing effect and ensuring uniform mixing of the refrigerant oil and additives. Furthermore, during the mixing process, the limiting strip on the outer wall of the second stirring rod 11 maintains the angle of the arc-shaped sliding block 13.

[0029] During the mixing process, the mixing drum 5 will vibrate. The mixing drum 5 drives the bottom plate 2 to slide on the inner wall of the base 1 through the support ring 4 and the support rod 3. The bottom plate 2 drives the rotating rod 20 to rotate through the connecting plate 21. The rotating rod 20 drives the slider 19 to slide on the outer wall of the slide rod 18. The second spring 22 plays a buffering role on the slider 19. At the same time, the damper 23 plays a damping and shock absorption role on the bottom plate 2, further buffering and shock absorption of the mixing drum 5, preventing the mixing drum 5 from generating large vibrations during the mixing process and causing equipment damage.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
