DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Example 1 A typical embodiment of the present invention is as follows Figure 1 As shown, a pipeline gas cooling sleeve device includes an upper shell 2 and a lower shell 3. The upper shell 2 and the lower shell 3 are sleeved on the outside of the outlet pipe 1. The upper shell 2 is hollow inside and has an opening at the bottom. The lower shell 3 is hollow inside and has an opening at the top. The upper shell 2 and the lower shell 3 cover each other to form a cooling cavity between the upper shell 2 and the lower shell 3.

The cold water inlet pipe 4 and the cold water outlet pipe 5 are both connected to the cooling cavity. The air outlet pipe 1 is connected to the compressor outlet. The cooling medium is transported to the inside of the cooling cavity through the cold water inlet pipe 4. When the high-temperature carbon dioxide gas is discharged from the compressor outlet, it enters the air outlet pipe 1. At the same time, the cooling medium enters the cooling cavity. Due to the temperature difference between the air outlet pipe 1 and the cooling cavity, the high-temperature carbon dioxide gas transfers heat to the cooling medium. After absorbing the heat, the temperature of the cooling medium rises and is discharged from the cold water outlet pipe 5, while the carbon dioxide gas is gradually cooled and the temperature drops. Finally, it flows out from the gas outlet and enters the subsequent process flow.

[0023] A limiting column 28 is fixed on the top of the clamping block 23, a first limiting hole 29 is opened on the clamping disc 25, and a second limiting hole 30 is opened on the clamping plate 24. The first limiting hole 29 and the second limiting hole 30 are arranged correspondingly, and the limiting column 28 passes through the first limiting hole 29 and the second limiting hole 30 respectively, thereby realizing a fixed connection between the clamping block 23, the clamping plate 24 and the clamping disc 25.

[0024] The bottom of the chuck 25 and the card plate 24 are both provided with a tooth plate 26 and a limit plate 27, and the tooth plate 26 and the limit plate 27 both extend toward one side of the lower shell 3, wherein the tooth plates 26 on the chuck 25 and the card plate 24 are arranged side by side, and the limit plates 27 on the chuck 25 and the card plate 24 are arranged side by side, and a tooth plate groove is provided on the card block 23 at a position corresponding to the tooth plate 26, and a limit plate groove is provided on the card block 23 at a position corresponding to the limit plate 27. When the chuck 25 and the card plate 24 are placed above the card block 23, the limit plate 27 is inserted into the limit plate groove, thereby limiting the chuck 25 and the card plate 24, and the tooth plate 26 is inserted into the tooth plate groove. A rack is provided on the tooth plate 26, which cooperates with the locking assembly to achieve the covering between the upper shell 2 and the lower shell 3.

[0025] like Figure 6 As shown, the locking assembly includes a connecting block 14, and there are four connecting blocks 14, which are symmetrically arranged on both sides of the lower shell 3. The two connecting blocks 14 on the same side are respectively fixed at the front end and the rear end of the lower shell 3. A rotating rod 18 is rotatably connected between the two connecting blocks 14. A plurality of connecting plates 17 are also provided on both sides of the lower shell 3. The plurality of connecting plates 17 are arranged side by side.

A plurality of gears 19 are fixedly connected to the outside of the rotating rod 18. The plurality of gears 19 are respectively meshed with the racks on the tooth plate 26.

[0027] When in use, the upper shell 2 and the lower shell 3 are sleeved on the outside of the air outlet pipe 1, the docking block 37 is engaged with the docking frame 38, the clamping plate 24 is inserted into the clamping plate 25, the toothed plate 26 and the limiting plate 27 are respectively passed through the toothed plate groove and the limiting plate groove, the rack on the toothed plate 26 is meshed with the gear 19, and the second knob 16 is turned. The second knob 16 drives the rotating rod 18 to rotate, and the rotating rod 18 drives the gear 19 to rotate. Since the rack on the toothed plate 26 is meshed with the gear 19, the gear 19 drives the toothed plate 26 to move downward, and the toothed plate 26 drives the clamping plate 24 and the clamping plate 25 to move downward, and the limiting post 28 passes through the first limiting hole 29 and the second limiting hole 30. The limiting post 28 limits the clamping plate 24 and the clamping plate 25, and the clamping plate 24 and the clamping plate 25 move down and press the clamping block 23, so that the upper shell 2 and the lower shell 3 fit each other, thereby the upper shell 2 and the lower shell 3 are sleeved on the outside of the air outlet pipe 1.

[0028] By setting up a snap assembly and a locking assembly, the upper and lower shells of the sleeve can be quickly snapped together and locked, avoiding the tedious operation of bolt fixing. The limit column 28 and the tooth plate-gear transmission system ensure that the snap is evenly stressed, preventing loosening due to vibration or thermal deformation, and adapting to long-term stable operation under high-pressure conditions. The worm 34 in the locking assembly is engaged with the worm wheel 33 and has a self-locking function, which can ensure that the position of the gear 19 after driving the tooth plate 26 to move is stable, thereby making the connection between the upper shell 2 and the lower shell 3 more firm and reliable.

[0029] In order to ensure the sealing between the upper shell 2 and the lower shell 3, a sealing assembly is also provided between the upper shell 2 and the lower shell 3. The sealing assembly includes a first seal 21 and a second seal 22. A placement groove 20 is provided at the junction of the bottom of the upper shell 2 and the lower shell 3, and at the junction of the top of the lower shell 3 and the upper shell 2.

The second hose 7 is connected to the second seal 22, and the second hose 7 is connected to the interior of the second seal 22.

[0030] like Figure 7 As shown, the end of the lower shell 3 is connected to the square shell 8 through two fixing columns 35. The interior of the square shell 8 is hollow. A connecting cylinder 11 is fixed to the side of the square shell 8 away from the lower shell 3. The interior of the connecting cylinder 11 is hollow and communicates with the interior of the square shell 8. A piston 36 is provided in the connecting cylinder 11. A threaded rod 12 is connected to one side of the piston 36. The threaded rod 12 extends to the outside of the connecting cylinder 11 and is threadedly connected to the connecting cylinder 11. A first knob 13 is provided on the end of the threaded rod 12 away from the piston 36. The second hose 7 is connected to the square shell 8.

Turn the first knob 13, the first knob 13 drives the threaded rod 12 to rotate, the threaded rod 12 rotates and pushes the piston 36 to move, and the piston 36 pushes the hydraulic oil. The hydraulic oil enters the first seal 21 and the second seal 22 respectively through the first hose 6 and the second hose 7, so that the first seal 21 and the second seal 22 are in closer contact, thereby improving the sealing performance of the connection between the upper shell 2 and the lower shell 3.

[0031] By setting a sealing assembly between the upper shell 2 and the lower shell 3, rotating the first knob 13 to push the piston 36, the internal pressure of the seal is adjusted in real time, so that the silicone seal fits tightly to the pipeline, compensates for wear or deformation, and significantly improves the durability of the seal. The first hose 6 and the square shell 8 are connected through the threaded pressure ring 10 and the connecting pipe 9, reducing the sealing structure's dependence on installation accuracy and reducing the risk of leakage.

[0032] Example 2 This embodiment provides a method for using a pipeline gas cooling sleeve device, using the pipeline gas cooling sleeve device as described in the first embodiment, including the following steps: The upper shell and the lower shell are sleeved on the outside of the air outlet pipe, the docking block is buckled with the docking frame, the clamping plate is inserted into the chuck, the clamping plate and the chuck are placed above the clamping block, the limiting column passes through the first limiting hole and the second limiting hole, and the second knob is turned. The gear drives the toothed plate to move downward, and the toothed plate drives the clamping plate and the chuck to move downward. The clamping plate and the chuck move downward and press the clamping block tightly, so that the upper shell and the lower shell fit tightly together; Connect the first hose to the connecting pipe, turn the first knob, and push the piston to move through the threaded rod, thereby pressing the hydraulic oil in the connecting cylinder and the square shell into the first seal and the second seal through the first hose and the second hose, so that the first seal and the second seal are in closer contact, thereby improving the sealing performance of the connection between the upper shell and the lower shell; The air outlet pipe is connected to the air outlet of the compressor, and the cooling medium enters the cooling cavity between the upper shell and the lower shell through the cold water inlet pipe. When the high-temperature carbon dioxide is discharged from the compressor, the heat is transferred to the cooling medium to cool the carbon dioxide gas, and finally flows out from the gas outlet and enters the subsequent process flow.

[0033] During installation, the present invention only requires clamping the upper shell and the lower shell on the outside of the air outlet pipe, performing a simple docking operation, and then turning the second knob to drive the worm, worm wheel, rotating rod and other components to rotate, thereby moving the clamping plate and the clamping disc downward to press the clamping block, thereby achieving a tight fit between the upper shell and the lower shell.
