Description

Technical Field

[0001] This utility model relates to the technical field of refrigerant recovery and storage devices, and in particular to a refrigerant recovery and storage device. Background Technology

[0002] In modern industrial production and refrigeration maintenance, refrigerant recovery and storage are crucial. With increasing global environmental regulations and the continued rise in the use of various refrigeration equipment, efficient, standardized, and convenient refrigerant recovery and storage operations are receiving increasing attention. Whether it's the regular maintenance of large refrigeration systems or the repair of small air conditioning units, a precise and reliable refrigerant recovery process is indispensable. This is not only crucial for the normal operation of equipment but also a key measure to reduce the environmental pollution caused by refrigerant leaks.

[0003] Traditional refrigerant recovery and storage devices suffer from numerous drawbacks in their tank securing methods. Commonly, they rely solely on simple clamps or ropes to fix the tank. In practice, operators spend a significant amount of time on tedious binding and unbinding operations. After recovery, untying the ropes is extremely inconvenient. This process is not only inefficient but also prone to safety hazards due to insecure securing. If the tank shifts during high-speed refrigerant injection, it may cause connecting pipes to rupture, leading to refrigerant leakage and harming the environment and operator health. Furthermore, traditional devices often lack effective management measures for the refrigerant inlet and outlet pipes. Connecting pipes are often placed haphazardly, easily becoming entangled and potentially damaged due to excessive pulling, leading to refrigerant leakage. To address these technical problems, this application proposes a refrigerant recovery and storage device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a refrigerant recovery and storage device. The device initially positions the storage tank using an arc-shaped retaining plate, then uses a motor to drive a shrinking roller to rotate. A traction rope pulls the arc-shaped clamping plate to secure the storage tank, and a fixing head locks the shrinking roller for stable fixation. After recovery, the storage tank can be easily disassembled by releasing the fixing head. Simultaneously, the winding roller can rotate flexibly, and the arc-shaped retaining block remains in place under the action of spring force, preventing the connecting pipes from becoming tangled and ensuring a stable and reliable recovery process, thus improving the efficiency and stability of refrigerant recovery operations.

[0022] 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.

[0023] Reference Figures 2-4This utility model provides an embodiment of a refrigerant recovery and storage device, comprising a trolley 1, a compressor 2 disposed at the front of the trolley 1, a storage tank 5 disposed at the rear of the trolley 1, a winding roller 6 rotatably connected to the outer wall of the compressor 2, a connecting pipe 7 disposed at the top of the compressor 2, the connecting pipe 7 being disposed on the outer wall of the winding roller 6, a support block fixedly connected to the outer wall of the compressor 2, one end of the support block being slidably connected to a limit shaft 8, an arc-shaped limit block 9 fixedly connected to the front end of the limit shaft 8, the inner wall of the arc-shaped limit block 9 being disposed on the outer wall of the winding roller 6, a spring 10 disposed on the outer wall of the limit shaft 8, a fixing block 11 fixedly connected to the middle of the trolley 1, and a fixed block 11 fixedly connected to the top of the fixing block 11. A sliding rod 12 is connected to the outer wall of the sliding rod 12, and an arc-shaped clamping plate 4 is slidably connected to the outer wall of the sliding rod 12. A spring 13 is provided on the outer wall of the sliding rod 12. A shrinking roller 16 is rotatably connected to the rear side of the arc-shaped clamping plate 4. A transmission gear 15 is fixedly connected to the bottom end of the shrinking roller 16. The two adjacent transmission gears 15 are meshed. The outer wall of the shrinking roller 16 and the rear end of the arc-shaped clamping plate 4 are fixedly connected to a fixing rod 17 on the outer wall of the fixing block 11 via a traction rope 20. A fixing head 19 is slidably connected to the outer wall of the fixing rod 17. A chuck is fixedly connected to the top end of the shrinking roller 16. The bottom side of the fixing head 19 is located on the top side of the chuck. A spring 18 is provided on the outer wall of the fixing rod 17 for clamping the storage tank 5.

[0024] Specifically, a winding roller 6 is installed on the outer wall of the compressor 2 at the front of the trolley 1. A connecting pipe 7 is wound around the winding roller 6. An arc-shaped limiting block 9 is pressed tightly against the outer wall of the winding roller 6 by the elastic force of spring 10, preventing the winding roller 6 from rotating and shaking. The arc-shaped clamping plate 4 is in the open position on the slide bar 12 under the elastic force of spring 23, the shrinking roller 16 is in the off state, and the storage tank 5 is initially limited by the arc-shaped backing plate 3. When preparing for recycling, one end of the connecting pipe 7 is connected to the equipment that needs to recover the refrigerant, and the other end is connected to the compressor 2. At this time, the motor 14 is started, and the motor 14 drives the transmission gear 15 to rotate. Due to the meshing connection between adjacent transmission gears 15, the shrinking roller 16 rotates synchronously, pulling the arc-shaped clamping plate 4 through the traction rope 20, clamping the storage tank 5. Spring 23 is compressed in this process. At the same time, the fixing head 19 presses the chuck under the elastic force of spring 318, thereby locking the shrinking roller 16 and achieving a stable clamping and fixing of the storage tank 5. During the refrigerant recovery process, compressor 2 is started, and the external refrigerant to be recovered enters compressor 2 under the suction action of compressor 2. After compression, it is transported to storage tank 5 for storage. At the same time, the winding roller 6 rotates flexibly according to the pulling out or retracting requirements of the connecting pipe 7 to meet the pipeline requirements during the refrigerant recovery process. After the refrigerant recovery work is completed, compressor 2 is turned off, the fixing head 19 is pulled up to disengage it from the chuck, and the arc-shaped clamp 4 is released from storage tank 5 under the rebound action of spring 13. Then, the connecting pipe 7 is manually arranged and wound back onto the winding roller 6, and the entire device returns to its initial state, thus completing one refrigerant recovery operation.

[0025] Reference Figures 1-3 A motor 14 is mounted on the front side of the fixed block 11 via a fixed frame. The drive end of the motor 14 is fixedly connected to the bottom side of one of the transmission gears 15. One end of the spring 10 is connected to the outer wall of the arc-shaped limiting block 9, and the other end of the spring 10 is connected to the outer wall of the support block. An arc-shaped backing plate 3 is fixedly connected to the top side of the trolley 1. The outer wall of the arc-shaped backing plate 3 is set on the outer wall of the storage tank 5.

[0026] Specifically, the motor 14 can control the winding and unwinding of the traction rope 20 by the shrinking roller 16. In conjunction with the fixed head 19 and the chuck at the top of the shrinking roller 16, the engagement and limiting between the chuck and the fixed head 19 are achieved. The spring 10 can ensure that the arc-shaped limiting block 9 and the winding roller 6 are always in contact, thereby limiting the winding roller 6 and preventing the connecting pipe 7 on its outer wall from becoming scattered due to the rotation of the winding roller 6. The arc-shaped backing plate 3 can limit the storage tank 5.

[0027] Working principle: In the initial state, the connecting pipe 7 is wound around the winding roller 6 on the outer wall of the compressor 2 at the front of the trolley 1. The arc-shaped limiting block 9 is pressed tightly against the outer wall of the winding roller 6 under the elastic force of spring 10, preventing it from rotating and shaking. The arc-shaped clamping plate 4 is in the open position on the slide bar 12 under the action of spring 2 13. The shrinking roller 16 is not started, and the storage tank 5 is initially limited by the arc-shaped backing plate 3. During the recovery preparation, one end of the connecting pipe 7 is connected to the recovery equipment, and the other end is connected to the compressor 2. The motor 14 is started, which drives the transmission gear 15 to rotate. The shrinking roller 16 rotates synchronously. The traction rope 20 pulls the arc-shaped clamping plate 4 to clamp the storage tank 5. Spring 2 13 is compressed. The fixing head 19 presses the chuck to lock the shrinking roller 16 under the action of spring 3 18, thereby clamping and fixing the storage tank 5. During recovery, the compressor 2 is started. The external refrigerant is drawn into the compressor 2, compressed, and then delivered to the storage tank 5. The winding roller 6 rotates flexibly according to the needs of the connecting pipe 7. After the refrigerant recovery is completed, shut off compressor 2, pull up the fixing head 19 to disengage from the chuck, and release the storage tank 5 under the rebound of spring 13. Manually arrange the connecting pipe 7 to wind back onto the winding roller 6, and the device returns to its initial state, completing one refrigerant recovery operation.

[0028] 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.
