Description

Technical Field

[0001] The invention relates to the field of refrigerant recovery, and in particular to a multi-voltage refrigerant recovery machine. Background Art

[0002] Different usage scenarios and regions may have different voltage standards. The multi-voltage refrigerator recovery machine can adapt to a variety of voltage inputs, such as the common 110V, 220V, 380V, etc., so that it can be used in regions with different voltage environments around the world, greatly improving the versatility and scope of use of the equipment, and reducing the limitations of use due to voltage mismatch.

[0003] However, when facing the recovery process of some refrigerants containing emulsion droplets, traditional multi-voltage refrigerant recovery machines only use simple gas-liquid separation methods such as gravity sedimentation or simple baffle separation. It is not effective to deal with refrigerants containing emulsion droplets. In this process, because the particle size of emulsion droplets is small and the stability is high, they will not settle quickly under the action of gravity or be intercepted by the baffle like ordinary large droplets.

[0004] At the same time, during the recovery process, even if there is a preliminary gas-liquid separation structure, the separated gas and liquid may be mixed again due to the air flow disturbance inside the recovery machine and the instability of liquid flow. For example, during the compressor suction process, the high-speed airflow may re-entrain the settled emulsified droplets, resulting in a significant reduction in the separation effect. Summary of the invention

[0005] Based on this, it is necessary to provide a multi-voltage refrigerant recovery machine to address the existing technical problems.

[0022] Second, the device performs secondary separation on the liquid refrigerant after centrifugal separation by setting up several spiral tubes. The self-rotation and revolution of the spiral tubes can guide the liquid to flow downward in a more orderly manner, and the self-rotation and revolution of the spiral tubes themselves will cause the liquid to produce a complex flow state in the spiral tubes. This complex flow state can further break the tiny bubbles that may exist in the liquid and achieve secondary separation of gas and liquid. At the same time, the centrifugal force generated by the rotation of the spiral tubes can prevent the liquid from refluxing during the collection process. In the case of some high-speed centrifugal separation, the liquid may reflux due to pressure difference or other factors, and the rotation of the spiral tubes can effectively overcome this situation, ensure the unidirectional flow of the liquid, and improve the collection efficiency.

[0023] Third: This device recovers the gaseous refrigerant by setting up an extrusion disk that can move back and forth in the vertical direction. When the extrusion disk moves downward, the space above the cone disk will be compressed. At this time, after the liquid refrigerant is squeezed, the tiny bubbles and droplet agglomerates inside it will be broken, thereby improving the separation efficiency.

[0035] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] refer to Figures 2 to 9 , a multi-voltage refrigerant recovery machine, comprising a recovery machine body 101, and further comprising:

[0037] The main tank 202 is arranged beside the recycling machine body 101 and is connected to the output end of the recycling machine body 101;

[0038] The recovery assembly 3 is connected to the main tank 202, and includes a centrifugal mechanism 4 and an extrusion mechanism 28. The centrifugal mechanism 4 includes a cone 8, a tray 10, a bottom plate 18, a plurality of spiral tubes 12 and a plurality of vibration mechanisms 22. The tray 10 is coaxially connected to the middle of the main tank 202, the cone 8 is fixedly connected to the upper end of the tray 10, the bottom plate 18 is coaxially arranged below the tray 10, the plurality of spiral tubes 12 are arranged on one side of the tray 10 close to the bottom plate 18, the plurality of spiral tubes 12 are arranged in an array at equal angles along the circumferential direction of the tray 10, the plurality of vibration mechanisms 22 are arranged in an array at equal angles along the circumferential direction of the lower end of the bottom plate 18, and the plurality of vibration mechanisms 22 correspond to the plurality of spiral tubes 12 one by one.

[0039] The extrusion mechanism 28 is connected to the main tank 202 and is arranged above the conical disk 8. The extrusion mechanism 28 includes an extrusion disk 29 and a plurality of opening and closing mechanisms 33. The extrusion disk 29 is coaxially slidably arranged above the conical disk 8, and the plurality of opening and closing mechanisms 33 are arranged in an array at equal angles along the circumferential direction of the extrusion disk 29.

[0040] refer to Figure 1 The multi-voltage power transmission principle of the recycling machine body 101 is that the recycling machine body 101 includes a power input terminal, an input rectifier filter circuit, a voltage detection circuit 1, a voltage doubler circuit and a control circuit 2. The power input and the voltage detection circuit and the rectifier filter circuit are connected in sequence. When the voltage detection circuit 1 detects that the input voltage is 110V, the control circuit 2 uses K1 to close, so that the voltages across the capacitors C1 and C2 are added, which plays a voltage doubler role. At this time, the DC voltage after the rectifier filter circuit is 110V*1.414*2 = 310V. When the voltage detection circuit 1 detects that the input voltage is 220V, the control circuit 2 uses K1 to disconnect. At this time, the DC voltage after the rectifier filter circuit is 220V*1.414 = 310V. Therefore, no matter the voltage at the power input is 110V or 220V, and the frequency is 50HZ or 60HZ, the recycling machine body 101 can automatically identify the voltage, ensuring the DC voltage at the output end of the recycling machine body 101 is stable and ensuring that the recycling machine body 101 can work smoothly.

[0041] When the device is in operation, after the recovery machine body 101 performs preliminary recovery of the mixed refrigerant, the mixed refrigerant will be sent to the main tank 202 for secondary recovery. After the mixed refrigerant flows into the main tank 202, the mixed refrigerant will be sprayed on the cone disk 8, the centrifugal mechanism 4 starts and drives the tray 10 and the cone disk 8 to rotate, and the mixed refrigerant sprayed on the cone disk 8 will undergo the first gas separation under the action of centrifugal force. In this process, the heavier liquid refrigerant will be thrown to the lower end of the cone disk 8 (i.e., the edge position of the tray 10), and the lighter gaseous refrigerant will be retained at the upper end of the cone disk 8 (i.e., the center position of the tray 10).

[0042] As the tray 10 rotates, the heavier liquid refrigerant will flow downward along the plurality of spiral tubes 12 and will eventually be collected. When the tray 10 rotates, the plurality of spiral tubes 12 will rotate along the circumferential direction of the tray 10, and the spiral tubes 12 will also rotate along their own axes. During the rotation of the spiral tubes 12, small bubbles mixed in the liquid refrigerant will be further removed and move upward along the spiral tubes 12. At the same time, the vibration mechanism 22 will push the spiral tubes 12 to vibrate back and forth in the vertical direction, thereby further increasing the speed of removing small bubbles.

[0043] During the rotation of the tray 10, the extrusion plate 29 will also reciprocate along the axial direction of the main tank 202. When the extrusion plate 29 moves downward, the extrusion plate 29 will use a number of opening and closing mechanisms 33 to allow the gaseous refrigerant to pass through the extrusion plate 29 upward and be collected. When the extrusion plate 29 moves upward, the extrusion plate 29 will use a number of opening and closing mechanisms 33 to prevent the gaseous refrigerant on the upper and lower sides of the extrusion plate 29 from flowing. At this time, small bubbles mixed in the liquid refrigerant will be drawn out and separated from the liquid refrigerant. At the same time, after the extrusion plate 29 is closed, it can also prevent part of the liquid refrigerant from passing through the extrusion plate 29 under the action of the suction force.

[0044] In order to collect the separated gaseous refrigerant and liquid refrigerant, the following features are specifically set:

[0045] The recovery component 3 further includes a gas tank 40 and a liquid tank 41. The gas tank 40 is arranged on a side of the main tank 202 away from the recovery machine body 101, and the gas tank 40 is communicated with the upper end of the main tank 202. The liquid tank 41 is arranged at the lower end of the gas tank 40 and communicated with the lower end of the main tank 202. After the mixed refrigerant is separated in the main tank 202, the gaseous refrigerant will flow into the gas tank 40 from the upper end of the main tank 202, and the liquid refrigerant will flow into the liquid tank 41 from the lower end of the main tank 202, thereby realizing the secondary separation of the gaseous refrigerant and the liquid refrigerant.

[0046] In order to drive the cone disk 8 to rotate, the following features are also specifically provided:

[0047] The centrifugal mechanism 4 also includes a motor 5, a bidirectional screw 6, a positioning cylinder 11 and a positioning frame 7. The positioning frame 7 is arranged above the extrusion disk 29 and is fixedly connected to the main tank 202 (refer to Figure 6 ), the motor 5 is fixedly arranged at the lower end of the main tank 202 (reference Figure 4 ), the lower end of the bidirectional screw 6 is coaxially fixedly connected to the output end of the motor 5, the upper end of the bidirectional screw 6 is rotatably connected to the positioning frame 7, the chassis 18 is fixedly connected to the bidirectional screw 6 through a sleeve, the cone plate 8 is fixedly connected to the tray 10 and is coaxially fixedly connected to the middle part of the bidirectional screw 6 through a sleeve. After the motor 5 is started, the motor 5 will drive the bidirectional screw 6 to rotate, and the rotation of the bidirectional screw 6 will drive the tray 10 and the cone plate 8 to rotate.

[0048] In order to facilitate the flow of liquid refrigerant on the cone 8, the following features are also specifically provided:

[0049] The cone 8 is formed with a plurality of guide grooves 9 in an array with equal angles along the circumferential direction (refer to Figure 6 ). After the liquid refrigerant is sprayed onto the cone disk 8, the plurality of guide grooves 9 on the cone disk 8 can increase the separation speed of the liquid refrigerant and the gaseous refrigerant.

[0050] In order to supplement the specific structure of the centrifugal mechanism 4, the following features are also specifically provided:

[0051] The centrifugal mechanism 4 further includes a positioning gear ring 20, a plurality of positioning gears 19, a plurality of top plates 13, a plurality of top sleeves 14, a plurality of bottom columns 16 and a plurality of bottom frames 17. The positioning gear ring 20 is arranged on one side of the bottom plate 18 close to the tray 10 (refer to Figure 6 ), the positioning gear ring 20 is coaxially fixedly connected to the main tank 202, a plurality of top plates 13 are arranged in an array with equal angles along the circumferential direction of the tray 10, a plurality of bottom frames 17 are arranged in an array with equal angles along the circumferential direction of the bottom plate 18, and a plurality of bottom columns 16 are coaxially fixedly connected to the upper ends of the plurality of bottom frames 17 (refer to Figure 8 ), several top sleeves 14 are respectively coaxially fixedly connected to the lower ends of several top plates 13, several top sleeves 14 are respectively slidably connected to several bottom pillars 16, several bottom frames 17 are respectively key-connected to several positioning gears 19, the top plate 13 is fixedly connected to the upper end of the spiral tube 12, and the bottom frame 17 is fixedly connected to the lower end of the spiral tube 12. When the tray 10 rotates, the tray 10 will drive several positioning gears 19 and the positioning gear ring 20 to engage, and the positioning gear ring 20 will drive several positioning gears 19 to rotate. At this time, the rotation of the positioning gear 19 will drive the bottom frame 17 to rotate, and the bottom frame 17 will drive the top plate 13 to rotate through the bottom pillar 16 and the top sleeve 14. In this process, the spiral tube 12 will rotate along the circumferential direction of the tray 10, and the spiral tube 12 will also rotate along its own axis. During the rotation of the spiral tube 12, small bubbles mixed in the liquid refrigerant will be further removed and move upward along the spiral tube 12.

[0052] In order to improve the elastic deformation force of the spiral tube 12 for resetting, the following features are also specifically provided:

[0053] The centrifugal mechanism 4 further includes a plurality of springs 15, which are respectively sleeved on the outside of the top sleeve 14 (refer to Figure 8 ), the upper end of the spring 15 is fixedly connected to the top plate 13, and the lower end is fixedly connected to the bottom frame 17. Under the action of the vibration mechanism 22, when the bottom frame 17 vibrates in the vertical direction, the spiral tube 12 is in a spiral shape, so the spiral tube 12 will be deformed during the vibration process, and the spring 15 will also be deformed, providing auxiliary force for the deformation of the spiral tube 12.

[0054] In order to supplement the specific structure of the vibration mechanism 22, the following features are also specifically provided:

[0055] The centrifugal mechanism 4 also includes a central gear ring 21 and a positioning cylinder 11. The vibration mechanism 22 includes a central gear 23, an active bevel gear 24, a bevel gear rack 25, a driven bevel gear 26 and a cam 27. The positioning cylinder 11 is sleeved on the outside of the bidirectional screw 6 and is coaxially rotatably connected to the lower end of the chassis 18. The positioning cylinder 11 is coaxially fixedly connected to the main tank 202 (refer to Figure 6 ), the center gear ring 21 is coaxially fixedly connected to the upper end of the positioning cylinder 11, the bevel gear frame 25 is fixedly connected to the lower end of the chassis 18, the center gear 23 is rotatably connected to the bevel gear frame 25 and meshes with the center gear ring 21, the active bevel gear 24 is rotatably connected to the bevel gear frame 25 and meshes with the center gear 23, the driven bevel gear 26 is rotatably connected to the bevel gear frame 25 and meshes with the active bevel gear 24, the cam 27 is rotatably connected to the bevel gear frame 25 and coaxially fixedly connected to the driven bevel gear 26, and the outer edge of the cam 27 abuts against the lower end of the chassis 17. When the chassis 18 drives several bevel gear racks 25 to rotate along the circumferential direction of the chassis 18, the center gear 23 will mesh with the center gear ring 21, and then the center gear 23 will rotate and drive the active bevel gear 24 to rotate, and the active bevel gear 24 will drive the cam 27 to rotate through the driven bevel gear 26. When the cam 27 rotates, it will push the chassis 17 that is against it to reciprocate in the vertical direction.

[0056] In order to realize the reciprocating movement of the squeezing disk 29 in the vertical direction, the following features are also specifically provided:

[0057] The extrusion mechanism 28 further includes a thread sleeve 32, a plurality of limit sleeves 30 and a plurality of limit pins 31, and the thread sleeve 32 is coaxially fixedly connected to the middle of the extrusion disc 29 (refer to Figure 6), the thread sleeve 32 is threadedly connected with the bidirectional screw rod 6, a plurality of limit sleeves 30 are arranged in an array at equal angles along the circumferential direction of the upper end of the extrusion disk 29, a plurality of limit pins 31 are arranged in an array at equal angles along the circumferential direction of the lower end of the positioning frame 7, and the limit sleeve 30 is slidably connected with the limit pin 31. When the bidirectional screw rod 6 rotates, the bidirectional screw rod 6 will drive the extrusion disk 29 to reciprocate in the vertical direction through the thread sleeve 32, and the extrusion disk 29 will be limited by the limit sleeve 30 and the limit pin 31 when moving.

[0058] In order to supplement the structure of the opening and closing mechanism 33, the following features are also specifically provided:

[0059] The opening and closing mechanism 33 includes a plurality of main gas disks 34, which are arranged in an array with equal angles along the circumference of the extrusion disk 29 (refer to Figure 7 ), the main gas disk 34 is fixedly connected to the extrusion disk 29, and the main gas disk 34 is formed with a plurality of air holes 35 in an array at equal angles along the circumferential direction. When the extrusion disk 29 moves downward, the gaseous refrigerant flows upward and passes through the plurality of air holes 35, and when the extrusion disk 29 moves upward, the plurality of air holes 35 are blocked (the specific blocking process is explained in detail later), and the gaseous refrigerant cannot pass through the plurality of air holes 35.

[0060] In order to realize the opening and blocking of the pore 35, the following features are also specifically provided:

[0061] The opening and closing mechanism 33 also includes a secondary gas disk 36, a push-pull shaft 38, a tension spring 39 and a plurality of gas plugs 37. The push-pull shaft 38 is coaxially connected to the main gas disk 34 for sliding connection (refer to Figure 7 ), the upper end of the push-pull shaft 38 is fixedly connected to the lower end of the auxiliary gas disk 36, and a plurality of gas plugs 37 are arranged in an array at equal angles along the circumferential direction of the lower end of the auxiliary gas disk 36. The gas plugs 37 are fixedly connected to the auxiliary gas disk 36 and extend into the corresponding air holes 35 when the extrusion disk 29 moves upward. The tension spring 39 is coaxially sleeved on the outside of the push-pull shaft 38, and the upper end of the tension spring 39 is fixedly connected to the auxiliary gas disk 36, and the lower end is fixedly connected to the main gas disk 34. When the extrusion disk 29 moves downward, since the gaseous refrigerant under the extrusion disk 29 will apply an upward thrust to the auxiliary gas disk 36, the auxiliary gas disk 36 will be pushed upward by the gaseous refrigerant at this time. At this time, the tension spring 39 is stretched, and the plurality of gas plugs 37 and the plurality of air holes 35 are separated. The gaseous refrigerant passes upward through the air holes 35 and is collected by the gas tank 40.

[0062] When the extrusion plate 29 moves upward, the gas tank 40 will extract the gaseous refrigerant above the extrusion plate 29, and the tension spring 39 will drive the auxiliary gas plate 36 to be pressed on the main gas plate 34 when the extrusion plate 29 moves upward. At this time, several air holes 35 are blocked, and as the extrusion plate 29 moves, small bubbles mixed in the liquid refrigerant will be drawn out and separated from the liquid refrigerant. At the same time, after the extrusion plate 29 is closed, part of the liquid refrigerant can be prevented from passing through the extrusion plate 29 under the action of the suction force.

[0063] The working principle of the device is that when the device is in operation, after the recovery machine body 101 performs preliminary recovery of the mixed refrigerant, the mixed refrigerant will be sent to the main tank 202 for secondary recovery. When the mixed refrigerant flows into the main tank 202, the motor 5 starts and drives the tray 10 and the cone disk 8 to rotate, and the mixed refrigerant on the cone disk 8 will undergo the first gas separation under the action of centrifugal force. During this process, the heavier liquid refrigerant will be thrown to the lower end of the cone disk 8 (i.e., the edge position of the tray 10), and the lighter gaseous refrigerant will be retained at the upper end of the cone disk 8 (i.e., the center position of the tray 10). Finally, the gaseous refrigerant will flow from the upper end of the main tank 202 into the gas tank 40, and the liquid refrigerant will flow from the lower end of the main tank 202 into the liquid tank 41, thereby realizing the secondary separation of the gaseous refrigerant and the liquid refrigerant.

[0064] During this process, as the tray 10 rotates, the heavier liquid refrigerant will flow downward along the plurality of spiral tubes 12 and will eventually be collected. When the tray 10 rotates, the plurality of spiral tubes 12 will rotate along the circumferential direction of the tray 10, and the spiral tubes 12 will also rotate along their own axes. When the spiral tubes 12 rotate, small bubbles mixed in the liquid refrigerant will be further removed and move upward along the spiral tubes 12. At the same time, the rotation of the cam 27 will drive the spiral tubes 12 to vibrate back and forth in the vertical direction, thereby further increasing the speed of removing small bubbles.

[0065] During the rotation of the tray 10, the extrusion plate 29 will also reciprocate along the axial direction of the main tank 202. When the extrusion plate 29 moves downward, the gaseous refrigerant passes upward through a plurality of air holes 35 and is collected by the gas tank 40. When the extrusion plate 29 moves upward, the auxiliary gas plate 36 will drive a plurality of gas plugs 37 to be inserted into the corresponding air holes 35 under the action of the tension spring 39. At this time, the gaseous refrigerant on the upper and lower sides of the extrusion plate 29 cannot flow. At this time, the small bubbles mixed in the liquid refrigerant will be drawn out and separated from the liquid refrigerant.
