Description

Technical Field

[0001] This application relates to the technical field of waste compressor recycling, and particularly to a swing-type oil draining device that can improve the oil draining rate of compressors. Background Art

[0002] With the enhancement of environmental awareness and the deepening of the concept of sustainable resource development, the field of waste household appliance product recycling has received increasing attention. Among the many waste household appliances that need to be recycled, the compressors in refrigerators and air conditioners are key recycling targets, and the recycling of the internal oil therein is of great significance. The oil in the compressor can be resold and recycled, which not only helps to reduce resource waste but also decreases the dependence on the production of new oil.

[0003] Under the existing technical conditions, for the operation of recycling the oil in the compressor, the commonly used method is as follows: First, use tools such as the drill bit of a stamping machine to pierce the iron sheet of the compressor housing, and then invert the compressor on the oil draining device. At this time, the residual oil in the compressor will flow into the oil collecting tank below through the oil draining holes formed by the piercing, and finally, the workers will remove the compressors from the oil draining device one by one. This recycling method is essentially static oil draining. However, this method has many drawbacks. Firstly, the oil draining time is long. Since only gravity is relied on to make the oil flow out naturally, the whole process takes a long time, greatly affecting the recycling efficiency. Secondly, the oil draining effect is poor. Only relying on gravity to make the oil flow out naturally easily leads to a large amount of oil being unable to be discharged smoothly, resulting in a large amount of recyclable oil being wasted. Thirdly, the workload is increased. Workers need to recycle the compressors after oil draining one by one, increasing the labor intensity of the workers. Summary of the Invention

[0004] In order to solve the technical problems of long oil draining time, poor oil draining effect and large manual workload in the existing technology, this application provides a swing-type oil draining device that can improve the oil draining rate of compressors.

[0005] A swing-type oil draining device that can improve the oil draining rate of compressors provided by this application adopts the following technical solutions: A swing-type oil draining device that can improve the oil draining rate of compressors includes: a swing mechanism, a conveying mechanism, a plurality of oil draining mechanisms, and an oil collecting box; The swing mechanism has a movable end that can swing reciprocally; The conveying mechanism has a fixed part and a conveying part that can move in a vertical plane around the fixed part, and the fixed part is fixed to the movable end; Each of the oil draining mechanisms includes an insertion cylinder, a retaining wall and a jetting part. The insertion cylinder is fixed to the conveying part and is used for inserting into the oil draining hole of the waste compressor. An air jet hole is formed in the side wall of the insertion cylinder. The retaining wall is fixed to the insertion cylinder and forms a space for accommodating the waste compressor. The air outlet end of the jetting part is communicated with the air jet hole, and air flow is ejected through the air jet hole to impact the waste compressor inserted on the insertion cylinder and make it collide with the retaining wall; The oil collecting box is arranged below each of the oil draining mechanisms and is used for collecting the engine oil discharged through the oil draining holes of the waste compressors inserted on each of the insertion cylinders.

[0006] By adopting the above technical solutions, the swinging mechanism drives the waste compressors on the conveying mechanism and the insertion cylinders to swing reciprocally, breaking the static state of the engine oil in the compressors, promoting the flow of the engine oil towards the oil draining holes and discharging it; meanwhile, the jetting part periodically ejects air flow, making the waste compressors collide with the retaining wall continuously, further promoting the discharge of the engine oil. The combination of multiple methods greatly shortens the oil draining time and improves the recycling efficiency. At the same time, through ways such as swinging, jetting impact and collision, the engine oil can flow more smoothly from the oil draining holes into the lower oil collecting box, reducing the waste of recyclable engine oil and enhancing the oil draining effect. In addition, when the waste compressors move to the lower end along with the conveying mechanism, they will fall off automatically under the action of gravity, facilitating the recycling of the drained compressors, without the need for workers to operate one by one, reducing the workload and labor intensity of the workers.

[0007] Preferably, the retaining wall includes a bracket and side baffles. The bracket is fixed to the insertion cylinder, and the side baffles are vertically fixed to both ends of the bracket.

[0008] By adopting the above technical solutions, the bracket is fixed to the insertion cylinder, which can provide a stable supporting plane for the waste compressors placed on the insertion cylinder. The side baffles are vertically fixed to both ends of the bracket. During the collision process between the waste compressor and the retaining wall, the side baffles can accurately limit the lateral movement range of the waste compressor. So that under the impact of the air flow ejected by the jetting part, the waste compressor can only collide with the retaining wall regularly within the space defined by the side baffles, ensuring the stability and controllability of the collision process, and further ensuring that the collision can continuously and effectively promote the discharge of the engine oil in the waste compressor.

[0009] Preferably, the retaining wall further includes a plurality of buffer pads, and the buffer pads are fixed to the inner side walls of the side baffles.

[0010] By adopting the above technical solution, the buffer pad is fixed to the inner side wall of the side baffle. When the airflow ejected from the jetting part impacts the waste compressor and causes it to collide with the enclosure, the buffer pad can play a buffering role and reduce the impact force between the waste compressor and the side baffle. This helps to avoid damage to the outer shell or internal structure of the waste compressor caused by severe collision. For some waste compressors that may need to have their components recycled and reused later, it can better preserve their integrity and increase the value of resource recovery. The buffer pad can also absorb part of the energy generated by the collision and reduce the noise and vibration generated during the collision. This not only improves the working environment, reduces the interference of noise to the operators, but also the reduced vibration is beneficial to the stability of the entire oil drainage device, avoiding loosening of the device components due to long-term vibration and extending the service life of the equipment.

[0011] Preferably, a first groove is formed on the side wall of the insertion cylinder, a second groove is formed on the bottom surface of the first groove, and the air jet hole is opened on the side wall of the second groove and communicates with the inner cavity of the insertion cylinder.

[0012] By adopting the above technical solution, the arrangement of the first groove and the second groove makes the position of the air jet hole relatively concealed, avoiding the direct entry of engine oil into the air jet hole and ensuring that the jetting part can continuously and stably eject airflow through the air jet hole.

[0013] Preferably, when the insertion cylinder is located above the conveying part, the outlet of the air jet hole is arranged downward.

[0014] By adopting the above technical solution, it further avoids the direct entry of engine oil into the air jet hole.

[0015] Preferably, an air inlet hole is opened on the insertion cylinder, the jetting part includes an air pump, and the outlet of the air pump communicates with the air inlet hole.

[0016] By adopting the above technical solution, the air pump can actively provide gas pressure and transport the gas into the insertion cylinder through the air inlet hole. This design makes the gas supply relatively stable and controllable, and the air pump can adjust the output pressure and flow rate according to needs to meet the usage requirements.

[0017] Preferably, the jetting part further includes a mounting bracket, one end of the mounting bracket is fixed to the insertion cylinder, and the other end of the mounting bracket is fixedly connected to the air pump.

[0018] By adopting the above technical solution, the mounting bracket plays a role of structural connection and support. One end of it is fixed to the insertion cylinder, and the other end is fixedly connected to the air pump, enabling the air pump to be kept stable.

[0019] Preferably, the swing mechanism includes a bottom plate, a top plate, a plurality of elastic members, and a vibrator. Two ends of each elastic member are respectively connected to the bottom plate and the top plate. An output shaft of the vibrator is connected to the top plate, and the fixing portion is fixed to the top plate.

[0020] By adopting the above technical solution, the output shaft of the vibrator is connected to the top plate. As the main power source, the vibrator can generate continuous and stable vibration energy. This vibration energy is transmitted to the top plate through the output shaft, and then drives the fixing portion of the conveying mechanism fixed on the top plate to move together. Since the vibrator can precisely adjust the vibration frequency and amplitude, it can provide suitable swing power according to the oil drainage requirements of different waste compressors, ensuring that the waste compressor promotes the oil discharge in the best swing state during the oil drainage process and improving the oil drainage efficiency.

[0021] Preferably, the fixing portion includes a column, a fixing frame, a driving wheel, a driven wheel, and a conveying driving member. One end of the column is fixed to the top plate, and the other end of the column is fixedly connected to the fixing frame. The fixing frame is inclined. The driving wheel and the driven wheel are respectively rotatably arranged at two ends of the fixing frame. The conveying driving member is connected to the driving wheel and is used to drive the driving wheel to rotate. The conveying portion is a conveyor belt. One end of the conveyor belt is wound around the driving wheel, and the other end of the conveyor belt is wound around the driven wheel.

[0022] By adopting the above technical solution, the conveying driving member is connected to the driving wheel. By driving the driving wheel to rotate, the conveyor belt wound around it is driven to operate. The driving wheel and the driven wheel are respectively arranged at two ends of the fixing frame. This layout enables the conveyor belt to maintain stable tension and transmission efficiency during operation.

[0023] Preferably, the swing-type oil drainage device capable of improving the oil drainage rate of the compressor further includes a receiving box, and the receiving box is located below the output end of the fixing frame.

[0024] By adopting the above technical solution, the receiving box can collect the waste compressors after oil drainage, so that the waste compressors have a centralized storage position after the oil drainage is completed, which is convenient for the staff to recycle and sort them uniformly.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The swing mechanism drives the conveying mechanism and the waste compressor on the inserting cylinder to swing reciprocally, breaking the static state of the engine oil in the compressor, promoting the flow of the engine oil towards the oil draining holes and discharging it. At the same time, the jetting part periodically jets airflows, causing the waste compressor to continuously collide with the enclosing fence, further promoting the discharge of the engine oil. The combination of multiple methods greatly shortens the oil draining time and improves the recycling efficiency. Meanwhile, through methods such as swinging, jetting, impacting, and colliding, the engine oil can flow more smoothly from the oil draining holes into the lower oil collecting box, reducing the waste of recyclable engine oil and enhancing the oil draining effect. In addition, when the waste compressor moves to the lower end along with the conveying mechanism, it will fall automatically under the action of gravity, facilitating the recycling of the oil-drained compressor without the need for workers to operate one by one, reducing the workload and labor intensity of the workers; 2. The settings of the first groove and the second groove, and the downward setting of the outlet of the air jet hole make the position of the air jet hole relatively concealed, preventing the engine oil from directly entering the air jet hole and ensuring that the jetting part can continuously and stably jet airflows through the air jet hole.

Detailed Embodiments

[0027] The following further elaborates on the present application in conjunction with the attached Figures 1 - 5 drawings for a more detailed description.

[0028] An embodiment of the present application discloses a swing-type oil draining device that can improve the oil draining rate of a compressor. Refer to Figure 1 As shown in Figure 1 , the swing-type oil draining device that can improve the oil draining rate of a compressor includes a swing mechanism 1, a conveying mechanism 2, a plurality of oil draining mechanisms 3, and an oil collecting box 4.

[0029] The swing mechanism 1 has a movable end that can swing reciprocally.

[0030] The conveying mechanism 2 has a fixed part 21 and a conveying part 22 that can move in a vertical plane around the fixed part 21, and the fixed part 21 is fixed to the movable end.

[0031] Each of the oil draining mechanisms 3 includes an insertion cylinder 31, a baffle 32, and a jet part 33. The insertion cylinder 31 is fixed to the conveying part 22 and is used to be inserted into the oil draining hole 51 of the waste compressor 5. A jet hole 311 is formed on the side wall of the insertion cylinder 31. The baffle 32 is fixed to the insertion cylinder 31 and forms a space for accommodating the waste compressor. The air outlet end of the jet part 33 is communicated with the jet hole 311, and air flow is ejected through the jet hole 311 to impact the waste compressor 5 inserted on the insertion cylinder 31 and make it collide with the baffle 32. In this embodiment, the outer diameter of the insertion cylinder 31 is much smaller than the inner diameter of the oil draining hole 51, so that it neither affects the discharge of the oil in the waste compressor 5 from the oil draining hole 51 nor prevents the lateral movement of the waste compressor 5.

[0032] The oil collecting box 4 is arranged below each of the oil draining mechanisms 3 and is used to collect the oil discharged from the oil draining hole 51 of the waste compressor 5 inserted on each insertion cylinder 31. In this embodiment, the oil collecting box 4 is independently fixed to the ground and does not contact the movable end of the swing mechanism 1, so as to avoid affecting the swing of the movable end of the swing mechanism 1.

[0033] During use, first, an opening operation is performed on the waste compressor 5 to form an oil-draining hole 51 on the compressor. The waste compressor 5 after opening is inverted so that the oil-draining hole 51 is located below. Then, the oil-draining hole 51 of the waste compressor 5 is put on the insertion cylinder 31 of the oil-draining mechanism 3. The conveying mechanism 2 is started to drive the insertion cylinder 31 to move. During the movement, the movable end of the swinging mechanism 1 begins to perform reciprocating swinging. Since the fixed part 21 of the conveying mechanism 2 is fixed to the movable end of the swinging mechanism 1, the insertion cylinder 31 will reciprocate with the swinging of the movable end, thereby driving the waste compressor installed on the insertion cylinder 31 to also reciprocate. This kind of swinging can break the static state of the engine oil in the compressor, promote the flow of the engine oil towards the oil-draining hole and discharge it. While the waste compressor is reciprocating, the jet part 33 periodically sprays out air flow through the air jet hole 311 to impact the waste compressor 5 inserted on the insertion cylinder 31 and make it collide with the enclosure 32. After the waste compressor 5 collides with one side of the enclosure 32, it will move in the reverse direction under the action of the recoil force and collide with the other side of the enclosure 32, and so on in a cycle. This kind of collision process further promotes the discharge of the engine oil in the waste compressor, enabling the engine oil to flow more smoothly from the oil-draining hole into the oil collecting box 4 below. When the waste compressor 5 moves to the lower end of the conveying mechanism 2 along with the movement of the conveying mechanism 2, due to no longer being supported by the insertion cylinder 31, under the action of gravity, the waste compressor drops, and at this time, it is convenient to recycle the oil-drained compressor, completing the entire oil-draining process.

[0034] The technical effects of the above technical solution are as follows: Compared with the prior art that only relies on natural oil draining by gravity, in this technical solution, the swinging mechanism drives the waste compressor on the conveying mechanism and the insertion cylinder to reciprocate, breaking the static state of the engine oil in the compressor, promoting the flow of the engine oil towards the oil-draining hole and discharging it; at the same time, the jet part periodically sprays out air flow, causing the waste compressor to continuously collide with the enclosure, further promoting the discharge of the engine oil. The combination of multiple methods greatly shortens the oil-draining time and improves the recycling efficiency. At the same time, through methods such as swinging, jet impact, and collision, the engine oil can flow more smoothly from the oil-draining hole into the oil collecting box below, reducing the waste of recyclable engine oil and improving the oil-draining effect. In addition, when the waste compressor moves to the lower end along with the conveying mechanism, it will drop automatically under the action of gravity, facilitating the recycling of the oil-drained compressor, without the need for workers to operate one by one, reducing the workload and labor intensity of workers.

[0035] In one of the embodiments, please refer to Figures 1 - 4, the enclosure 32 includes a bracket 321 and side guards 322. The bracket 321 is fixed to the insertion cylinder 31, and the side guards 322 are vertically fixed to both ends of the bracket 321. In this embodiment, the bracket 321 is fixed to the insertion cylinder 31, which can provide a stable support plane for the waste compressor placed on the insertion cylinder 31. The side guards 322 are vertically fixed to both ends of the bracket 321. During the collision between the waste compressor and the enclosure, the side guards can accurately limit the lateral movement range of the waste compressor. So that under the impact of the airflow ejected by the jet part, the waste compressor can only collide with the enclosure regularly within the space defined by the side guards, ensuring the stability and controllability of the collision process, and further ensuring that the collision can continuously and effectively promote the discharge of the oil in the waste compressor.

[0036] In one embodiment, please refer to Figures 1 - 4 , the enclosure 32 further includes a plurality of buffer pads 323, and the buffer pads 323 are fixed to the inner sidewalls of the side guards 322. In this embodiment, the buffer pads 323 are fixed to the inner sidewalls of the side guards 322. When the jet part 33 ejects airflow to impact the waste compressor and cause it to collide with the enclosure 32, the buffer pads can play a buffering role and reduce the impact force between the waste compressor and the side guards. This helps to avoid damage to the outer shell or internal structure of the waste compressor due to violent collision. For some waste compressors that may need to recycle parts later, it can better retain their integrity and improve the value of resource recovery. The buffer pads can also absorb part of the energy generated by the collision and reduce the noise and vibration generated during the collision. This not only improves the working environment and reduces the interference of noise to the operator, but also the reduced vibration is beneficial to the stability of the entire oil draining device, avoiding loosening of the device parts due to long-term vibration and extending the service life of the equipment.

[0037] In one embodiment, please refer to Figures 1 - 4 , a first groove 312 is formed on the sidewall of the insertion cylinder 31, a second groove 313 is formed on the bottom surface of the first groove 312, and the air jet holes 311 are opened on the sidewall of the second groove 313 and communicate with the inner cavity of the insertion cylinder 31. In this embodiment, the settings of the first groove 312 and the second groove 313 make the position of the air jet holes 311 relatively concealed, avoiding direct entry of oil into the air jet holes 311 and ensuring that the jet part 33 can continuously and stably eject airflow through the air jet holes 311.

[0038] In one embodiment, please refer to Figures 1 - 4, when the insertion cylinder 31 is located above the conveying part 22, the outlet of the air injection hole 311 is arranged downward, thereby further preventing the engine oil from directly entering the air injection hole 311. After the gas is ejected downward from the air injection hole 311, it will enter the second groove 313. Since the opening direction of the second groove 313 faces the side of the insertion cylinder 31, the gas will deflect and be ejected from the side of the insertion cylinder 31 after entering the second groove 313.

[0039] In one embodiment, please refer to Figures 1 - 4 , an air inlet hole 314 is formed in the insertion cylinder 31, and the air jetting part 33 includes an air pump 331. The outlet of the air pump 331 is communicated with the air inlet hole 314. In this embodiment, the air pump 331 can actively provide gas pressure and transport the gas into the insertion cylinder 31 through the air inlet hole 314. This design makes the supply of gas relatively stable and controllable. The air pump 331 can adjust the output pressure and flow rate according to needs to meet the usage requirements.

[0040] In one embodiment, please refer to Figures 1 - 4 , the air jetting part 33 further includes a mounting bracket 332. One end of the mounting bracket 332 is fixed to the insertion cylinder 31, and the other end of the mounting bracket 332 is fixedly connected to the air pump 331.

[0041] In one embodiment, please refer to Figure 1 , the swing mechanism 1 includes a bottom plate 11, a top plate 12, a plurality of elastic members 13 and a vibrator 14. Two ends of the elastic member 13 are respectively connected to the bottom plate 11 and the top plate 12. The output shaft of the vibrator 14 is connected to the top plate 12, and the fixing part 21 is fixed to the top plate 12. In this embodiment, the output shaft of the vibrator 14 is connected to the top plate 12. As the main power source, the vibrator 14 can generate continuous and stable vibration energy. This vibration energy is transmitted to the top plate 12 through the output shaft, and then drives the fixing part 21 of the conveying mechanism 2 fixed to the top plate 12 to move together. Since the vibrator 14 can accurately control the vibration frequency and amplitude, it can provide suitable swing power according to the oil draining requirements of different waste compressors, ensure that the waste compressor promotes the oil discharge in the best swing state during the oil draining process, and improve the oil draining efficiency.

[0042] In one embodiment, please refer to Figure 1, the fixing part 21 includes a column 211, a fixing frame 212, a driving wheel 213, a driven wheel 214 and a conveying driving member. One end of the column 211 is fixed to the top plate 12, and the other end of the column 211 is fixedly connected to the fixing frame 212. The fixing frame 212 is inclined. The driving wheel 213 and the driven wheel 214 are respectively rotatably arranged at both ends of the fixing frame 212. The conveying driving member is connected to the driving wheel 213 and is used to drive the driving wheel 213 to rotate. The conveying part 22 is a conveyor belt. One end of the conveyor belt is wound around the driving wheel 213, and the other end of the conveyor belt is wound around the driven wheel 214. One end of the inserting cylinder 31 is fixed to the conveyor belt. In this embodiment, the conveying driving member is connected to the driving wheel 213. By driving the driving wheel 213 to rotate, the conveyor belt wound around it is driven to operate. The driving wheel 213 and the driven wheel 214 are respectively arranged at both ends of the fixing frame 212. This layout enables the conveyor belt to maintain stable tension and transmission efficiency during operation.

[0043] In one embodiment, please refer to Figure 1 , the swing type oil draining device capable of improving the oil draining rate of the compressor further includes a receiving box 6. The receiving box 6 is located below the output end of the fixing frame 212. In this embodiment, the receiving box 6 can collect the waste compressor 5 after oil draining, so that there is a centralized storage position for the waste compressor after oil draining, which is convenient for the staff to recycle and sort uniformly.

[0044] In one embodiment, please refer to Figure 1 and Figure 5 , an oil drain port 41 is opened at a lower position on the side wall of the oil collecting box 4, and an oil drain valve 42 is arranged on the oil drain port 41. When the oil collected in the oil collecting box 4 exceeds a certain liquid level height, the oil drain valve 42 can be opened to drain the oil.

[0045] To better understand the present application, the following is combined with Figures 1 to 5A detailed description of the technical solution of this application: During use, first, an opening operation is performed on the waste compressor 5 to form an oil-draining hole 51 on the compressor. The waste compressor 5 after opening is inverted so that the oil-draining hole 51 is located below, and then the oil-draining hole 51 of the waste compressor 5 is put on the insertion cylinder 31 of the oil-draining mechanism 3. The conveying mechanism 2 is started to drive the insertion cylinder 31 to move. During the movement, the movable end of the swinging mechanism 1 starts to swing reciprocally. Since the fixed part 21 of the conveying mechanism 2 is fixed to the movable end of the swinging mechanism 1, the insertion cylinder 31 will swing reciprocally along with the swing of the movable end, and then drive the waste compressor installed on the insertion cylinder 31 to also swing reciprocally. This kind of swing can break the static state of the engine oil in the compressor, promote the flow of the engine oil towards the oil-draining hole and discharge it. While the waste compressor is swinging reciprocally, the jet part 33 periodically sprays out airflows through the air jet holes 311 to impact the waste compressor 5 inserted on the insertion cylinder 31 and make it collide with the enclosure 32. After the waste compressor 5 collides with one side of the enclosure 32, it will move in the reverse direction under the action of the recoil force and collide with the other side of the enclosure 32, and so on in a cycle. This collision process further promotes the discharge of the engine oil in the waste compressor, enabling the engine oil to flow more smoothly from the oil-draining hole into the oil collection box 4 below. When the waste compressor 5 moves to the lower end of the conveying mechanism 2 along with the movement of the conveying mechanism 2, due to no longer being supported by the insertion cylinder 31, under the action of gravity, the waste compressor drops, and at this time, it is convenient to recycle the oil-drained compressor, completing the entire oil-draining process.

[0046] The technical effects of the technical solution provided by this application include: (1) Driving the waste compressor on the conveying mechanism and the insertion cylinder to swing reciprocally through the swinging mechanism, breaking the static state of the engine oil in the compressor, promoting the flow of the engine oil towards the oil-draining hole and discharge it; at the same time, the jet part periodically sprays out airflows, making the waste compressor continuously collide with the enclosure, further promoting the discharge of the engine oil. The combination of multiple methods greatly shortens the oil-draining time and improves the recycling efficiency; (2) Through methods such as swinging, jet impact, and collision, enabling the engine oil to flow more smoothly from the oil-draining hole into the oil collection box below, reducing the waste of recyclable engine oil, and improving the oil-draining effect; (3) When the waste compressor moves to the lower end along with the conveying mechanism, it will drop automatically under the action of gravity, facilitating the recycling of the oil-drained compressor without the need for workers to operate one by one, reducing the workload and labor intensity of workers; (4) The settings of the first groove 312 and the second groove 313, and the downward setting of the outlet of the air jet hole 311 make the position of the air jet hole 311 relatively concealed, avoiding the direct entry of engine oil into the air jet hole 311 and ensuring that the jet part 33 can continuously and stably spray out airflows through the air jet hole 311.

Any other corresponding changes and deformations made according to the technical concept of the present application shall be included in the protection scope of the present application.
