[0029] See also Figure 1-Figure 7 As shown, this embodiment is a centrifugal compressor circulating air cooling system, comprising a rectangular frame 1, on which a compression tank 18 is fixedly mounted, and a cooling mechanism is connected through the heat dissipation end of the compression tank 18;

[0030] The cooling mechanism includes a bearing seat 2 fixedly connected to the rectangular frame 1, two symmetrically arranged connecting frames 3 are fixedly connected to the upper surface of the bearing seat 2, and cooling pipes 10 are penetrated and inserted into the two connecting frames 3. A fan 8 is arranged on one side of the top of the rectangular frame 1;

[0031] Preliminary heat dissipation treatment is carried out through the cooling pipe 10, and the fan 8 rotates to speed up the flow rate of air near the cooling pipe 10. A mounting frame 6 is fixedly connected to one side of the outer wall of the rectangular frame 1, and a sliding seat 13 is vertically slidably connected to the mounting frame 6. The sliding seat 13 is penetrated and rotatably connected with a cleaning pipe 11. A plurality of nozzles 12 are connected through the outer wall of the cleaning pipe 11. The cleaning pipe 11 is connected to an external conveying pipe through a rotating joint. By setting a rotating joint, interference during cleaning is prevented, and external circulating water is transported into the cleaning pipe 11, and the cooling pipe 10 is flushed through the plurality of nozzles 12 arranged on the cleaning pipe 11. When the sliding seat 13 moves in the vertical direction, the cooling pipe 10 can be cleaned along the vertical direction to prevent dust from being adsorbed on the cooling pipe 10 and reduce the impact of dust on the cooling pipe 10.

[0032] Two connecting frames 3 are symmetrically arranged, and the two connecting frames 3 are fixed on the supporting seat 2 in a V shape to increase the heat dissipation area. The V-shaped arrangement facilitates the fan 8 to dissipate heat from the connecting frames 3. When the cleaning tube 11 rotates, the cooling tube 10 is fully cleaned by the nozzle 12 on the cleaning tube 11.

[0033] The top ends of the two connecting frames 3 are fixedly connected with a mounting plate 4, and the mounting plate 4 is penetrated and fixedly connected with a mounting cover 5. The fan 8 is located in the mounting cover 5, and the fan 8 is rotatably connected to the limiting seat in the mounting cover 5. The cooling pipe 10 reciprocates horizontally along the supporting seat 2 and penetrates the connecting frame 3, thereby increasing the heat dissipation area and improving the heat dissipation efficiency.

[0034] The cooling pipe 10 passes through the connecting frame 3 and extends along the direction of the supporting seat 2. A shunt pipe 9 is set on one side of one of the connecting frames 3. The shunt pipe 9 is connected to the connecting frame 3 along the outer wall of the connecting frame 3. High-temperature and high-pressure air enters the connecting frame 3 through the shunt pipe 9 for heat dissipation.

[0035] A baffle 7 is fixedly connected between the two connecting frames 3, and an opening is opened on the surface of one of the baffles 7 for the cleaning pipe 11 to move in the vertical direction. A plurality of nozzles 12 are arranged in a circular array, and the plurality of circular nozzles 12 extend along the direction of the cleaning pipe 11. The nozzles 12 are high-pressure nozzles, and the nozzles 12 are evenly distributed, so that the cooling pipes 10 on both sides of the support seat 2 can be fully cleaned.

[0036] Embodiment 2:

[0037] This embodiment is used to solve the problem of how to further improve the cooling efficiency.

[0038] See also Figure 1-Figure 7As shown, a centrifugal compressor circulating air cooling system of this embodiment has a tooth plate 16 fixedly connected to one side of the mounting frame 6, and a gear 17 is passed through and fixedly connected to the cleaning pipe 11, and the gear 17 is meshed with the tooth plate 16. When the sliding seat 13 moves in the vertical direction, the cleaning pipe 11 can move in the vertical direction and rotate at the same time, thereby increasing the flushing range of the cleaning pipe 11 in the vertical direction.

[0039] A limiting groove 15 is provided on the surface of the mounting frame 6 for vertical sliding connection of the sliding seat 13, and a sliding groove is provided on the inner wall of the limiting groove 15. A sliding block 19 fixedly connected to the sliding seat 13 is vertically slidably connected to the inner wall of the sliding groove of the limiting groove 15. A screw 20 is rotatably connected to the fixed axis in the sliding groove of the limiting groove 15. The screw 20 penetrates the sliding block 19 and is screwed to the sliding block 19. A motor 14 for driving the screw 20 to rotate is fixedly installed on the upper surface of the mounting frame 6. When the motor 14 is started, the motor 14 drives the screw 20 to rotate, so that the sliding block 19 pushes the sliding seat 13 to move in the vertical direction, so that the cleaning pipe 11 rotatably connected to the sliding seat 13 cleans the cooling pipes 10 on the two connecting frames 3 along the vertical direction to remove the dust adsorbed on the surface of the cooling pipes 10.

[0040] Combining Embodiment 1 with Embodiment 2

[0041] By setting up a cooling mechanism, the cooling pipe 10 performs preliminary heat dissipation treatment on the heat dissipation end of the compression tank 18, which effectively reduces the working temperature of the compression tank 18. The rotation of the fan 8 accelerates the air flow near the cooling pipe 10, further improves the heat dissipation efficiency, and ensures the stable operation of the compressor. The cleaning pipe 11 and multiple nozzles 12 flush the cooling pipe 10 through external circulating water, effectively removing dust and dirt on the cooling pipe 10. The movement of the sliding seat 13 in the vertical direction causes the cleaning pipe 11 to rotate, and can perform comprehensive cleaning along the distribution direction of the cooling pipe 10. The cooling mechanism and the cleaning mechanism are compactly installed on the rectangular frame 1, which optimizes the spatial layout and reduces the floor space. It has the advantages of efficient heat dissipation, easy cleaning, compact and flexible structure, simple maintenance, and strong adaptability.

[0042] like Figure 1-Figure 7 As shown, the working process and principle of the present invention are as follows:

[0043] Start the fan 8 located in the mounting cover 5. The fan 8 accelerates the air flow inside the connecting frame 3. The number of fans 8 and mounting covers 5 can be arranged according to actual conditions. Start the motor 14. The motor 14 drives the screw 20 to rotate, so that the sliding block 19 pushes the sliding seat 13 to move in the vertical direction, so that the cleaning pipe 11 rotatably connected to the sliding seat 13 cleans the cooling pipes 10 on the two connecting frames 3 along the vertical direction. Under the action of the gear 17 and the tooth plate 16, when the sliding seat 13 moves in the vertical direction, the cleaning pipe 11 can be rotated while moving in the vertical direction, thereby increasing the flushing range of the cleaning pipe 11 in the vertical direction, and can fully remove the dust adsorbed on the surface of the cooling pipe 10, thereby improving the subsequent heat dissipation effect.
