Description

Technical Field

[0001] This utility model relates to the field of bearing waste ring recycling technology, specifically a pollution-free secondary recycling device for nickel-molybdenum bearing waste rings. Background Technology

[0002] In the field of recycling waste bearing rings, rings made of nickel-molybdenum materials have high strength and wear resistance, making them valuable for recycling. However, their pre-treatment process, especially the removal of surface oil stains, has long been constrained by technical bottlenecks, making it difficult to meet the requirements for efficient, environmentally friendly, and highly adaptable secondary utilization.

[0003] The specifications of waste bearing rings vary. Traditional degreasing devices mostly use fixed clamps to fix the rings, which can only accommodate rings of a single size. If different sizes of rings need to be processed, the clamps need to be changed manually or the device components need to be adjusted, which is cumbersome and time-consuming. In addition, the depth of the rings immersed in the degreasing solution and the adjustment of the degreasing position also depend on manual operation. Not only is it difficult to guarantee accuracy, but insufficient immersion depth can lead to incomplete degreasing, or excessive depth can cause the rings to be bumped. It also greatly increases the labor intensity of the operators and reduces the overall processing efficiency. In view of this, a pollution-free secondary utilization device for waste bearing rings containing nickel and molybdenum is proposed. Utility Model Content

[0015] (III) Beneficial Effects Compared with the prior art, this utility model provides a pollution-free secondary utilization device for nickel-molybdenum-containing bearing waste rings, which has the following beneficial effects: 1. This nickel-molybdenum-containing bearing waste ring recycling device is pollution-free. The device uses an air compressor, a delivery pipe, and a bubble jet pipe to spray a large number of bubbles into the degreasing tank. Combined with the heating function of the heating pipe to raise the temperature of the degreasing liquid, it can thoroughly flush the oil stains on the surface of the rings and accelerate the removal of oil stains. Compared with the traditional static degreasing, the efficiency is improved. At the same time, with the linkage of the second lead screw, knob and fixed frame, the distance between the two positioning columns can be flexibly adjusted to adapt to different sizes of rings.

Throughout the process, ring clamping, degreasing position adjustment, and rinsing transfer are all achieved through a combination of motor drive and manual fine-tuning. For example, the first motor controls the ring lifting and lowering, and the knob quickly fixes the rings. The operation steps are simple and easy to understand, requiring no complex professional skills, reducing the labor intensity of operators. At the same time, the stable cooperation of each component reduces the impact damage to the rings during transfer, improving the secondary utilization qualification rate. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-5 This utility model provides a new technical solution: a pollution-free secondary utilization device for waste bearing rings containing nickel and molybdenum, including an oil removal tank 1: as one of the core processing areas of the device, it is mainly used to contain the oil removal agent and the waste rings to be processed, providing a closed space for subsequent oil removal operations, while supporting the installation of components such as heating pipe 6 and bubble jet pipe 5, ensuring the stable progress of the oil removal process, and is the key carrier for achieving the initial removal of oil stains on the surface of the rings.

[0021] Rinsing tank 2: Adjacent to and fixedly connected to degreasing tank 1, it is used to receive the degreased rings. It can be filled with clean water or rinsing agent. The residual degreasing agent on the surface of the rings is cleaned by the agitation of impeller 22, completing the secondary purification. At the same time, it provides the installation foundation for components such as the second motor 17 and transmission roller 21, ensuring the orderly conduct of the rinsing process.

[0022] Air compressor 3: Located on the front surface of the oil removal tank 1, it is the power source for the bubble jet. It generates high-pressure airflow by compressing air, and delivers the airflow to the bubble jet pipe 5 through the delivery pipe 4. This provides sufficient air pressure for the subsequent bubble flushing of the oil stains on the surface of the ring, ensuring that the oil stains can be effectively removed during the oil removal process and improving the oil removal efficiency.

[0023] Delivery pipe 4: Fixed at the output end of air compressor 3, it plays the role of airflow conduction, stably delivering the high-pressure air generated by air compressor 3 to bubble jet pipe 5. Its sealing structure can prevent airflow leakage, ensure that the air pressure loss is minimized during transmission, and ensure that bubble jet pipe 5 can continuously obtain stable airflow to maintain the oil removal effect.

[0024] Bubble jet pipe 5: Connected to the output end of the delivery pipe 4, installed inside the degreasing tank 1, it can convert the high-pressure air transmitted from the delivery pipe 4 into dense bubbles. The rising and breaking of the bubbles in the degreasing agent generates jet impact force, which directly acts on the surface of the ring, washing away the attached oil stains, and realizing the combination of physical degreasing and chemical degreasing.

[0025] Heating tubes 6: There are two in total, which are fixed on opposite sides of the vertical plate of the degreasing tank 1. After being powered on, they can generate heat and transfer it to the degreasing agent in the degreasing tank 1, raising the temperature of the degreasing agent to a suitable range, enhancing the activity of the degreasing agent, accelerating the separation speed of oil stains from the surface of the ring, and at the same time avoiding the degreasing agent from failing due to excessive temperature, thus ensuring stable degreasing effect.

[0026] Guide rail 7: Installed on the rear surface of the degreasing tank 1, it provides sliding guidance for the moving block 8, restricts the movement trajectory of the moving block 8, and ensures that the moving block 8 can only move horizontally or vertically along the guide rail 7 (according to the device design), so as to avoid the moving block 8 from deviating during the transfer of the ring, and ensure that the ring can be accurately adjusted in position within the degreasing tank 1 or transferred to the rinsing tank 2.

[0027] Moving block 8: Sliding sleeve on the outer surface of guide rail 7, it is the key carrier connecting guide rail 7 with other transmission components. The first lead screw 9 is rotatably connected inside, and the guide roller 10 and the first motor 11 are fixedly installed outside. It can move on guide rail 7, and at the same time, it supports the lifting and lowering of moving plate 12 through its own structure, so as to realize the transfer of the ring at different processing positions.

[0028] First lead screw 9: Rotatably connected to the inner wall of moving block 8, with its upper end passing through moving block 8 and connected to first motor 11. It is a transmission component and can rotate clockwise or counterclockwise under the drive of first motor 11. Through threaded transmission, it drives moving plate 12 to move up and down along guide roller 10, thereby adjusting the height of the ring and facilitating the immersion or removal of the ring from the degreasing agent.

[0029] Guide rollers 10: There are two of them, which are fixed on the opposite side of the horizontal plate of the moving block 8 and are set parallel to the first lead screw 9. The moving plate 12 is slidably sleeved on its outer surface. They mainly play the role of guiding and limiting, preventing the moving plate 12 from rotating or deviating when the first lead screw 9 drives the lifting and lowering, ensuring that the moving plate 12 always maintains stable vertical movement and ensuring the accurate position of the ring.

[0030] First motor 11: Fixed on the upper end of the moving block 8, with its output shaft fixedly connected to the upper end of the first lead screw 9, it is the power source for the rotation of the first lead screw 9. By receiving control signals, it can achieve forward and reverse rotation, drive the first lead screw 9 to rotate synchronously, and thus control the lifting speed and position of the moving plate 12, providing stable power support for the height adjustment of the ring.

[0031] Movable plate 12: It is threaded on the outer surface of the first lead screw 9 and slidably sleeved on the guide roller 10. It is the basic component that supports the fixed frame 15 and the positioning column 16. It can move up and down with the guide roller 10 under the drive of the first lead screw 9, driving the collar to be immersed in the degreasing agent in the degreasing tank 1 or to be removed from the degreasing agent. At the same time, it provides an installation position for the second lead screw 13, realizing the bearing of the collar fixing structure.

[0032] The second lead screw 13 is rotatably connected to the upper surface of the moving plate 12. A knob 14 is installed at the upper end. It is a fine-tuning transmission component. The forward and reverse rotation is achieved by manually rotating the knob 14. The screw drive drives the fixed frame 15 to move up and down along the moving plate 12, thereby adjusting the distance between the two positioning columns 16 to meet the fixing requirements of different sizes of waste rings.

[0033] Knob 14: Fixed to the upper end of the second lead screw 13, providing a manual adjustment interface for the operator. By rotating the knob 14, the second lead screw 13 can be driven to rotate without the need for additional tools. This allows the operator to quickly adjust the spacing of the positioning pins 16 according to the actual size of the ring, improving the convenience of the ring fixing operation and ensuring the efficiency of the fixing process.

[0034] Fixed frame 15: The horizontal plate is threaded on the outer surface of the second lead screw 13, and the vertical plate is slidably sleeved on the inner surface of the moving plate 12. It is one of the mounting carriers of the positioning column 16. Driven by the second lead screw 13, it can slide up and down along the moving plate 12. It works with the positioning column 16 on the moving plate 12 to clamp and fix the collar, preventing the collar from shaking or shifting during the cleaning process.

[0035] Positioning pins 16: Two pins are fixed to the opposite sides of the moving plate 12 and the horizontal plate of the fixed frame 15, respectively. They are available in three types: straight cylindrical, conical, and drum-shaped. Their core function is to position and clamp the rings. The straight cylindrical type is suitable for standard-sized rings, the conical type facilitates quick insertion of rings, and the drum-shaped type can enhance the fixing stability of irregular rings, ensuring that the rings maintain a fixed posture during cleaning and improving the uniformity of cleaning.

[0036] The second motor 17 is fixed in the inner wall of the rinsing tank 2 and is the power source for the rinsing process. After being powered on, the output shaft can rotate stably, driving the first pulley 18 to rotate synchronously. The power is transmitted to the second pulley 20 through the belt drive, providing continuous power for the rotation of the impeller 22 and ensuring that the water flow in the rinsing tank can form an effective agitation.

[0037] First pulley 18: Fixedly sleeved on the outer surface of the output shaft of the second motor 17, it is the driving pulley of the belt drive. It rotates with the output shaft of the second motor 17 and drives the belt 19 to circulate through the friction with the belt 19, so as to efficiently transmit the power of the second motor 17 to the driven pulley (second pulley 20) and realize the direction and transmission of power.

[0038] Belt 19: It is a transmission connection between the outer surface of the first pulley 18 and the inner surface of the second pulley 20. It is an intermediate medium for power transmission. Through its own elasticity and friction, it synchronously transmits the rotational motion of the first pulley 18 to the second pulley 20, ensuring that the power loss is small during transmission and ensuring that the impeller 22 can rotate stably.

[0039] The second pulley 20 is connected to the inner surface of the belt 19 and fixedly sleeved on the outer surface of the transmission roller 21. It is a driven pulley of the belt drive. It rotates under the drive of the belt 19, thereby driving the transmission roller 21 to rotate synchronously, realizing the conversion of power from belt drive to roller shaft drive, and providing direct power for the rotation of the impeller 22.

[0040] Transmission roller 21: It is fixedly sleeved on the inner surface of the second pulley 20, with its lower end rotatably connected to the inner wall of the rinsing tank 2, and its upper end penetrating into the rinsing tank 2 and installing the impeller 22. It plays the role of power transmission and support, transmitting the rotational motion of the second pulley 20 to the impeller 22, and at the same time ensuring that the impeller 22 can evenly agitate the water flow through its own rotational stability.

[0041] Impeller 22: It is fixedly sleeved on the outer surface of the drive roller 21 and located in the rinsing tank 2. When it rotates with the drive roller 21, it can agitate the clean water or rinsing agent in the rinsing tank, forming a rotating water flow and local eddy current, which can rinse the surface of the ring, remove residual degreasing agent and fine oil particles, improve the cleanliness of the ring, and ensure the quality of the ring for reuse.

[0042] This pollution-free secondary utilization device for nickel-molybdenum-containing bearing waste rings involves the operator placing the waste bearing rings onto the positioning pins 16 on the moving plate 12. Turning the knob 14 rotates the second lead screw 13. Because the horizontal plate of the fixed frame 15 is threaded to the second lead screw 13 and the vertical plate is slidably connected to the moving plate 12, the fixed frame 15 moves downwards with the rotation of the second lead screw 13. The positioning pins 16 at its bottom gradually approach the upper surface of the ring until both positioning pins 16 clamp the ring together, completing the clamping process. The device is then used to process the degreasing fluid in the degreasing tank 1. When the first motor 11 is started, it drives the first lead screw 9 to rotate. Since the moving plate 12 is threadedly connected to the first lead screw 9 and is limited by the guide roller 10, the moving plate 12 moves downward along the guide roller 10 until the clamped ring is completely immersed in the degreasing liquid. If it is necessary to adjust the front and back position of the ring in the degreasing tank 1, the moving block 8 can be pushed to slide back and forth along the guide rail 7 until the appropriate degreasing position is reached. Then, the air compressor 3 and the heating pipe 6 are turned on. The heating pipe 6 heats the degreasing liquid and raises the temperature. The high-pressure gas generated by the air compressor 3... The oil enters the bubble jet pipe 5 through the conveying pipe 4. The bubble jet pipe 5 sprays a large number of bubbles into the degreasing liquid. As the bubbles rise, they disturb the degreasing liquid, thoroughly washing the surface of the ring, peeling off and removing the oil, thus completing the degreasing process. After degreasing, the first motor 11 is started in reverse, driving the first lead screw 9 to rotate in the opposite direction. The moving plate 12 moves upward along the guide roller 10, lifting the ring away from the degreasing liquid. The moving block 8 is pushed to slide along the guide rail 7 towards the rinsing tank 2 until the ring moves directly above the rinsing tank 2. The first motor 11 is started again, making... The moving plate 12 moves the ring downwards until it is immersed in the rinsing water of the rinsing tank 2; the second motor 17 is turned on, which drives the first pulley 18 to rotate, and through the belt 19, drives the second pulley 20 and the transmission roller 21 to rotate. The transmission roller 21 drives the impeller 22 to rotate, and the impeller 22 agitates the rinsing water to form a water flow, rinsing the ring and removing residual degreasing liquid and oil stains; after rinsing, the first motor 11 drives the moving plate 12 to rise again, lifting the ring out of the rinsing water, completing the entire cleaning process; Standard size rings for straight cylindrical positioning posts in batch processing scenarios like Figure 3 As shown: A bearing recycling plant has accepted a batch of uniformly sized, nickel-molybdenum-containing waste deep groove ball bearing rings. Batch degreasing pretreatment is required, which demands high clamping efficiency and stable positioning to avoid uneven degreasing caused by the rings shifting during air bubble flushing.

[0043] The operator checks the surface flatness of the cylindrical positioning pins to ensure there are no burrs or deformations. The collars are then fitted one by one onto the cylindrical positioning pins of the moving plate 12. Because the gap between the outer diameter of the positioning pin and the inner diameter of the collar is only 2mm, the collars can quickly align and naturally conform to the outer wall of the positioning pin. Rotating the knob 14 drives the second lead screw 13, causing the cylindrical positioning pins below the fixing frame 15 to slowly descend until the two positioning pins respectively abut against the upper and lower ends of the collars, completing the clamping. No excessive adjustment is needed; the clearance fit directly achieves stable fixation. The first motor 11 is then started to immerse the collars in… In the degreasing tank, the air compressor and heating element are turned on. When the bubble jet washes the surface of the ring from all directions, the cylindrical surface of the straight positioning post fits tightly against the inner wall of the ring, limiting the radial sway of the ring. The straight positioning post is compatible with the inner diameter of standard-sized rings, so there is no need to repeatedly adjust the position of the positioning post when clamping in batches. The clamping time of a single ring is shortened to less than 10 seconds. At the same time, the large contact area between the cylindrical surface and the inner wall of the ring avoids the ring displacement caused by the bubble jet. After degreasing, the oil residue rate on the surface of the ring is less than 3%, which meets the efficiency and quality requirements of batch processing.

[0044] Example 1: Quick clamping scenario of worn and deformed conical positioning post ring like Figure 4 As shown: A mechanical repair shop is processing a batch of scrap tapered roller bearing rings containing nickel and molybdenum. Due to long-term use, some rings have worn deformation of 0.5-1mm in the inner diameter, and there are slight scratches on the inner wall. Traditional straight cylindrical positioning pins are prone to loosening due to excessive clearance, or causing secondary damage to the inner wall of the rings due to forced insertion. Using a conical positioning post, the collar is slowly inserted from the top of the positioning post. Due to the gradual diameter change of the conical structure, even if there are differences in wear between the inner diameters of the collars, the inner wall of the collar can still find a suitable contact point with the conical surface of the positioning post. The collar with less wear is stuck in the upper middle part of the positioning post, and the collar with more wear is stuck in the lower middle part. There is no need to replace the positioning post. Turning knob 14 lowers the upper conical positioning post. The conical surfaces of the two conical positioning posts press against the end face of the collar from the top and bottom, using the anti-slip properties of the conical surfaces to limit the axial movement of the collar. Start the moving block to move along the guide rail. After sliding to the degreasing position, the ring is immersed in the degreasing solution. The radial force generated by the air bubbles is offset by the friction between the conical surface and the inner wall of the ring, and the ring always maintains a stable posture. The gradual diameter of the conical positioning post is adapted to the difference in the inner diameter of the worn and deformed ring, so there is no need to adjust the positioning structure for a single ring. The clamping success rate is increased from 75% of the traditional straight cylindrical type to 100%. At the same time, the conical surface fit avoids the forced compression of the inner wall of the ring, and the secondary damage rate is reduced to 0. After degreasing, there is no oil residue at the scratches on the inner wall of the ring, which meets the accuracy requirements of subsequent secondary processing.

[0045] Example 2: Scenario of stabilizing and fixing an irregularly thick drum-shaped positioning post with a collar. like Figure 5 As shown: A special bearing recycling project processes a batch of scrap self-aligning ball bearing rings containing nickel and molybdenum. Due to design requirements, these rings have an irregular shape with thicker walls at the edges and thinner walls at the corners. In addition, the end faces of the rings are slightly warped. Traditional straight or tapered locating pins are prone to causing the rings to tilt due to the small contact area, which affects the uniformity of degreasing.

[0046] Using a drum-shaped positioning post, align the inner wall of the ferrule with the drum-shaped protrusion in the center of the positioning post and insert it. The thickened structure in the center of the drum-shaped positioning post precisely fits the thicker area in the middle of the inner wall of the ferrule, increasing the contact area compared to a straight cylindrical positioning post. Even if the end face of the ferrule warps, the protrusion in the center of the positioning post can limit the radial tilt of the ferrule. Turning knob 14 lowers the upper drum-shaped positioning post, and the drum-shaped sections of the two positioning posts "wrap" and clamp the ferrule from both ends. The curved surface of the drum-shaped structure can adapt to the warping shape of the ferrule end face, avoiding excessive local pressure that could cause ferrule deformation. Open the rinsing tank. During rinsing, the drum-shaped positioning post makes multiple contacts with the inner wall of the bearing ring, which can counteract the torque generated by the rotation of the water flow. The bearing ring does not shift or flip. The raised structure in the middle of the drum-shaped positioning post is highly compatible with the inner wall shape of the irregular wall thickness of the bearing ring. The increased contact area improves the fixing stability of the bearing ring by 60%. During rinsing, the inclination rate of the bearing ring is reduced from 30% of the traditional positioning post to 0%. At the same time, the arc-shaped surface fit avoids damage to the warped end face. The end face flatness error of the bearing ring during secondary use is controlled within 0.1mm, which meets the assembly accuracy requirements of special bearings.
