Description

Technical Field

[0001] This utility model relates to the field of compression precooling technology, specifically to a multi-stage compression precooling device. Background Technology

[0002] Multistage compression precooling equipment refers to equipment used to cool gas between compression stages in a multistage compression refrigeration system. Multistage compression refrigeration systems divide the compression process into multiple stages, gradually increasing the pressure at each stage, and setting up precooling equipment between each compression stage to reduce the gas temperature, thereby reducing the power consumption required for the next compression stage and improving system efficiency.

[0003] Patent No. 202321827094.0 discloses a compressed air precooler. This device is equipped with a removable refrigeration pipe, which can be disassembled and cleaned when dust adheres to the surface of the refrigeration pipe.

[0004] However, existing compressed air precoolers use structures such as mounting sleeves and sliding levers to disassemble the sealing cover, allowing the refrigeration pipes to be removed from the precooling housing. However, disassembling the refrigeration pipes requires manual operation of the mounting sleeves, sliding levers, and operating blocks on both sides of the precooling housing, making the process cumbersome and impacting the efficiency of refrigeration pipe disassembly. Furthermore, the threaded end cap on the top of the filter housing requires manual separation of the end cap from the filter housing when cleaning the filter screen, resulting in a large workload and low efficiency in cleaning the filter screen. Therefore, a multi-stage compression precooling device is needed. Utility Model Content

[0005] To address the problems in the background art, this utility model provides a multi-stage compression precooling device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a multi-stage compression precooling device, including a fixed frame. A compressor B is bolted to one side of the fixed frame. A fixed frame supporting the compressor B is bolted to the bottom of the compressor B. An input pipe for gas entry into the compressor B is screwed to the outside of the compressor B. A branch pipe D is screwed to the end of the compressor B away from the input pipe. A housing B is screwed to the end of the branch pipe D away from the compressor B. A branch pipe C is bolted to the outside of the housing B, and a compressor A is screwed to one end of the branch pipe C. A branch pipe B is screwed to the end of the compressor A away from the branch pipe C. A housing A is screwed to end B. A branch pipe A is screwed to the outside of housing A, and a filter box is screwed to one side of branch pipe A. A filter screen is screwed to the inside of the filter box, and a box cover is snapped into the inside of the filter box. An output pipe for gas discharge is inserted into the outside of the filter box. A cover A is placed on top of housing A. A support rod is welded to the outside of cover A. A cover B is welded to the end of the support rod away from cover A. A refrigeration pipe for pre-cooling the gas is screwed to one side of both cover A and cover B. A drive plate is symmetrically welded to the outside of cover A, and a wedge block A is welded to the inside of the drive plate. A transmission component that drives the support rod to move is installed inside the fixing frame.

[0007] By adopting the above technical solution, air enters compressor B through the input pipe. Compressor B is a low-pressure compressor that compresses the air. The air is then delivered to housing B through branch pipe D. The refrigeration pipes in housing B cool the air. The cooled air then enters compressor A through branch pipe C. Compressor A is a high-pressure compressor that compresses the air again. The compressed air is then delivered to housing A through branch pipe B. The refrigeration pipes in housing A further cool the air. The pre-cooled air is then delivered to the filter box through branch pipe A for filtration, and then delivered through the output pipe on one side of the filter box.

[0008] Specifically, the filter box has symmetrically formed grooves on its surface, springs are symmetrically welded inside the box cover, and a wedge-shaped block B is welded to one side of each spring.

[0009] By adopting the above technical solution, when the support rod moves the shell cover A and shell cover B, shell cover A moves the externally symmetrically installed drive plate. Then the drive plate moves the inner wedge block A. Then wedge block A pushes the wedge block B in the groove, so that wedge block B presses the spring on one side, so that wedge block A enters the box cover, so that the box cover is released from fixation, separating the box cover from the filter box, which facilitates the disassembly and cleaning of the filter screen in the filter box.

[0010] Specifically, the transmission assembly includes a motor, a reducer, a worm, a worm wheel, a threaded sleeve, a threaded screw, and a transmission rod. The motor, which provides power, is bolted to the outside of the fixed frame. The reducer is connected to a flange on one side of the motor. The worm is keyed to the inside of the reducer, and a worm wheel is meshed to the outside of the worm. A threaded screw is splined to the inside of the worm wheel. A threaded sleeve is threaded to the outside of the threaded screw. A transmission rod, which connects to the bottom of the support rod, is welded to the outside of the threaded sleeve.

[0011] By adopting the above technical solution, when the condenser needs to be disassembled and cleaned, the motor outside the fixed frame is driven by the PLC controller to drive the worm gear to rotate through the reducer. Then the worm gear meshes with the external worm wheel, and the worm wheel drives the inner threaded screw to rotate. Then the threaded sleeve outside the threaded screw is limited by the external structure. The threaded sleeve drives the transmission rod to move longitudinally upward. Then the transmission rod pushes the support rod to move upward. Then the support rod drives the shell covers A and B on both sides to move, so that shell cover A moves off the shell A and shell cover B moves off the shell B. Then shell covers A and shell cover B drive the refrigerant pipe to move out, which facilitates the disassembly and cleaning of the refrigerant pipe.

[0012] Specifically, rubber pads are adhered to the inner sides of both shell cover A and shell cover B.

[0013] By adopting the above technical solution, when the cover A is connected to the top of the housing A and the cover B is connected to the top of the housing B, the rubber gasket inside the cover A is tightly connected to the housing A, and the rubber gasket inside the cover B is connected to the housing B, thereby improving the sealing performance of the housing A and the housing B.

[0014] Specifically, the input terminals of the motor, compressor A, compressor B, and reducer are all electrically connected to the power supply terminal of an external power source.

[0015] By adopting the above technical solution and connecting to an external power source, the electrical equipment can operate normally.

[0016] The beneficial effects of this utility model are:

[0017] (1) In the multi-stage compression precooling equipment described in this utility model, when the condenser needs to be disassembled and cleaned, the motor outside the fixed frame is driven by the PLC controller to drive the worm gear to rotate through the reducer. Then the worm gear meshes with the external worm wheel, and then the worm wheel drives the inner threaded screw to rotate. Then the threaded sleeve outside the threaded screw is limited by the external structure. The threaded sleeve drives the transmission rod to move longitudinally upward. Then the transmission rod pushes the support rod to move upward. Then the support rod drives the shell covers A and B on both sides to move, so that shell cover A moves out of shell A and shell cover B moves out of shell B. Then shell cover A and shell cover B drive the refrigeration pipe to move out, thereby facilitating the disassembly and cleaning of the refrigeration pipe.

[0018] (2) In the multi-stage compression precooling device described in this utility model, when the support rod drives the shell cover A and shell cover B to move, the shell cover A drives the externally symmetrically installed drive plate to move. Then the drive plate drives the inner wedge block A to move. Then the wedge block A pushes the wedge block B in the groove, so that the wedge block B presses the spring on one side, so that the wedge block A enters the box cover, so that the box cover is released from fixation, and the box cover is separated from the filter box, which facilitates the disassembly and cleaning of the filter screen in the filter box.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] To perform multi-stage compression and pre-cooling of air, as one embodiment of this utility model, such as Figures 1 to 4As shown, the multi-stage compression precooling device of this utility model includes a fixed frame 5. A compressor B14 is bolted to one side of the fixed frame 5. The bottom of the compressor B14 is bolted to the fixed frame 5 supporting the compressor B14. An input pipe 15 for allowing gas to enter the compressor B14 is screwed to the outside of the compressor B14. A branch pipe D13 is screwed to the end of the compressor B14 away from the input pipe 15. A housing B17 is screwed to the end of the branch pipe D13 away from the compressor B14. A branch pipe C10 is bolted to the outside of the housing B17, and a compressor A9 is screwed to one end of the branch pipe C10. A branch pipe B8 is screwed to the end of the compressor A9 away from the branch pipe C10. A housing A6 is fixed with screws. A branch pipe A3 is screwed to the outside of the housing A6, and a filter box 4 is screwed to one side of the branch pipe A3. A filter screen 30 is screwed to the inside of the filter box 4. A box cover 1 is snapped into the inside of the filter box 4. An output pipe 2 for gas discharge is inserted into the outside of the filter box 4. A shell cover A7 is placed on the top of the housing A6. A support rod 16 is welded to the outside of the shell cover A7. A shell cover B12 is welded to the end of the support rod 16 away from the shell cover A7. A refrigeration pipe 11 for pre-cooling the gas is screwed to one side of both the shell cover A7 and the shell cover B12. A drive plate 25 is symmetrically welded to the outside of the shell cover A7, and a wedge block A26 is welded to the inside of the drive plate 25. A transmission assembly 20 for moving the support rod 16 is provided inside the fixing frame 5.

[0027] In use, air enters compressor B14 through inlet pipe 15. Compressor B14 is a low-pressure compressor that compresses the air. The air is then delivered to housing B17 through branch pipe D13. The refrigeration pipe 11 in housing B17 cools the air. The cooled air then enters compressor A9 through branch pipe C10. Compressor A9 is a high-pressure compressor that compresses the air again. The compressed air is then delivered to housing A6 through branch pipe B8. The refrigeration pipe 11 in housing A6 further cools the air. The pre-cooled air is then delivered to filter box 4 through branch pipe A3 for filtration, and then delivered through outlet pipe 2 on one side of filter box 4.

[0028] To disassemble and clean the filter screen 30 inside the filter box 4, for example, as follows: Figure 3 As shown, the present invention also includes grooves 28 symmetrically formed on the surface of the filter box 4, springs 29 symmetrically welded inside the box cover 1, and a wedge block B27 welded to one side of the springs 29.

[0029] When in use, when the support rod 16 moves the housing cover A7 and housing cover B12, the housing cover A7 moves the externally symmetrically mounted drive plate 25. Then, the drive plate 25 moves the inner wedge block A26. Then, the wedge block A26 pushes the wedge block B27 in the groove 28, so that the wedge block B27 presses the spring 29 on one side, so that the wedge block A26 enters the box cover 1, so that the box cover 1 is released from the fixation, separating the box cover 1 from the filter box 4, which makes it easier to disassemble and clean the filter screen 30 in the filter box 4.

[0030] For disassembling and cleaning the cooling pipe 11, for example, such as Figure 4 As shown, this utility model also includes the transmission assembly 20, which includes a motor 23, a reducer 24, a worm 32, a worm wheel 22, a threaded sleeve 21, a threaded screw 18, and a transmission rod 19. The fixed frame 5 is externally bolted to the motor 23, which provides power. The reducer 24 is connected to a flange on one side of the motor 23. The worm 32 is keyed to the inside of the reducer 24, and the worm wheel 22 is externally meshed with the worm 32. The threaded screw 18 is splined to the inside of the worm wheel 22. The threaded sleeve 21 is threaded to the outside of the threaded screw 18. The transmission rod 19, which is connected to the bottom of the support rod 16, is welded to the outside of the threaded sleeve 21.

[0031] When the condenser needs to be disassembled and cleaned during use, the external motor 23 of the mounting bracket 5, driven by the PLC controller, drives the worm gear 32 to rotate through the reducer 24. Then, the worm gear 32 meshes with the external worm wheel 22, which in turn drives the inner threaded screw 18 to rotate. The threaded sleeve 21 outside the threaded screw 18 is limited by the external structure, and the threaded sleeve 21 drives the transmission rod 19 to move longitudinally upward. Then, the transmission rod 19 pushes the support rod 16 to move upward. Then, the support rod 16 drives the shell covers A7 and B12 on both sides to move, so that the shell cover A7 moves off the shell A6 and the shell cover B12 moves off the shell B17. Then, the shell covers A7 and B12 drive the refrigerant pipe 11 to move out, which facilitates the disassembly and cleaning of the refrigerant pipe 11.

[0032] To improve the sealing performance of housing A6 and housing B17, for example, such as Figure 2 As shown, the present invention also includes rubber pads 31 bonded to the inner sides of both the shell cover A7 and the shell cover B12.

[0033] When in use, when the cover A7 is connected to the top of the housing A6 and the cover B12 is connected to the top of the housing B17, the rubber gasket 31 inside the cover A7 is tightly connected to the housing A6, and the rubber gasket 31 inside the cover B12 is connected to the housing B17, thereby improving the sealing performance of the housing A6 and the housing B17.

[0034] For electrical equipment to function properly, for example, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention also includes that the input terminals of the motor 23, compressor A9, compressor B14 and reducer 24 are all electrically connected to the power supply terminal of an external power source.

[0035] When in use, the electrical equipment works normally by connecting to an external power source.

[0036] In use, air enters compressor B14 through input pipe 15. Compressor B14 is a low-pressure compressor that compresses the air. The air is then delivered to housing B17 through branch pipe D13. The refrigeration pipe 11 inside housing B17 cools the air. The cooled air then enters compressor A9 through branch pipe C10. Compressor A9 is a high-pressure compressor that compresses the air again. The compressed air is then delivered to housing A6 through branch pipe B8. The refrigeration pipe 11 inside housing A6 further cools the air. The pre-cooled air is then delivered to filter box 4 through branch pipe A3 for filtration, and then delivered through output pipe 2 on one side of filter box 4. When the condenser needs to be disassembled and cleaned, the external motor 23 of the mounting bracket 5, controlled by the PLC controller, drives the worm gear 32 to rotate via reducer 24. The worm gear 32 then meshes with the external worm wheel 22, which in turn drives the internal worm wheel 22. The threaded screw 18 rotates, and then the threaded sleeve 21 outside the threaded screw 18 is limited by the external structure. The threaded sleeve 21 drives the transmission rod 19 to move longitudinally upward. Then the transmission rod 19 pushes the support rod 16 to move upward. Then the support rod 16 drives the shell covers A7 and B12 on both sides to move, so that the shell cover A7 moves off the shell A6 and the shell cover B12 moves off the shell B17. Then the shell covers A7 and B12 drive the refrigeration pipe 11 to move out, which facilitates the disassembly and cleaning of the refrigeration pipe 11. At the same time, the shell cover A7 drives the externally symmetrically installed drive plate 25 to move. Then the drive plate 25 drives the inner wedge block A26 to move. Then the wedge block A26 pushes the wedge block B27 in the groove 28, so that the wedge block B27 presses the spring 29 on one side, so that the wedge block A26 enters the box cover 1, so that the box cover 1 is released from the fixation, separating the box cover 1 from the filter box 4, which facilitates the disassembly and cleaning of the filter screen 30 in the filter box 4.
