Therefore, it is urgent to design a self-heating structure that rotates with the rotating part to reduce the temperature of the rotating air joint. Utility Model Content

Therefore, it is urgent to design a self-heating structure that rotates with the rotating part to reduce the temperature of the rotary air joint.

[0004] The utility model provides the following technical solution: a self-heat dissipation structure of a rotary air joint of a shaking bag centrifuge, comprising a rotary air joint body, a top closed protective cover is arranged on the top of the rotary air joint body, and an air inlet connecting pipe is arranged on the top closed protective cover;

[0020] See also Figure 1-4

[0021] Embodiment 1: A self-heat dissipation structure of a rotary air joint of a bag-shaking centrifuge comprises a rotary air joint body 1 , a top closed protective cover 2 is arranged at the top of the rotary air joint body 1 , and an air inlet connecting pipe 3 is arranged on the top closed protective cover 2 .

[0022] An internal air connecting pipe 4 is arranged in the middle of the air intake connecting pipe 3, and the internal air connecting pipe 4 is communicated with the rotating air joint body 1. An O-ring 5 is arranged on the outer side of the air intake connecting pipe 3, and a side connecting pipe 6 is arranged on the side of the bottom of the top closed protective cover 2. A rotating connecting seat 7 is rotatably arranged at the bottom end of the rotating air joint body 1, and a rotating mounting seat 8 is arranged below the rotating connecting seat 7.

[0023] The rotating connecting seat 7 and the rotating mounting seat 8 are rotatably connected via a rotating ventilation pipe 9, on which a plurality of heat dissipation fan blades 10 are evenly arranged. A bottom joint 11 is rotatably arranged at the bottom end of the rotating mounting seat 8, and a first connecting pipe 12 is connected to the side of the bottom joint 11. A second connecting pipe 13 is arranged below the first connecting pipe 12, and the second connecting pipe 13 is connected to the bottom end of the bottom joint 11.

[0024] Embodiment 2: The difference between this embodiment and embodiment 1 is that, the O-ring 5 is closely attached to the upper end surface of the top closed protective cover 2 .

[0025] This allows the O-ring 5 to better seal when the top closing cover 2 is connected to the centrifuge.

[0026] Embodiment 3: The difference between this embodiment and embodiment 1 is that the heat dissipation fan blade 10 is composed of a hollow disk and a plurality of fan blades arranged on the side of the hollow disk.

[0027] The unique fan-shaped structure of the heat dissipation fan blade 10 can increase the air volume of the rotating part and reduce the temperature of the rotating air joint by physical cooling.

[0028] Embodiment 4: The difference between this embodiment and embodiment 1 is that a plurality of semicircular grooves are evenly arranged on the inner wall of the heat dissipation fan blade 10 .

[0029] This makes the connection between the heat dissipation fan blades 10 and the rotating ventilation pipe 9 more convenient and firm.

[0030] In this embodiment, since the rotating air joint of the bag shaking centrifuge is a high-speed rotating part, the part itself will generate excessive heat during the high-speed rotation process. The high temperature will cause the internal seals of the part to age and fail, thereby causing the rotating air joint to leak and affect the normal operation of the bag shaking action. Therefore, it is urgent to design a self-heating structure that rotates with the rotating part to reduce the temperature of the rotating air joint.

[0031] In summary, in the specific implementation, a rotating connecting seat 7 is provided at the bottom of the rotating air joint body 1, and a rotating ventilation pipe 9 is rotatably provided between the rotating connecting seat 7 and the rotating mounting seat 8. As the rotating ventilation pipe 9 rotates, the air flowing through the rotating air joint body 1 and the inside of the rotating ventilation pipe 9 can be rotated, and the air gradually rotates faster as the air pressure gradually increases, in order to reduce the susceptibility of the connecting sealing gasket between the rotating ventilation pipe 9 and the rotating connecting seat 7 to the high temperature during the rotation process.

[0032] By evenly installing a plurality of heat dissipation blades 10 on the outside of the rotating ventilation pipe 9, the heat dissipation blades 10 can rotate with the rotation of the rotating ventilation pipe 9. Through the unique fan-shaped structure of the heat dissipation blades 10, the air volume of the rotating ventilation pipe 9 is increased during the rotation process, thereby achieving physical cooling of the rotating ventilation pipe 9 during the rotation process, thereby reducing the temperature of the overall structure, thereby effectively reducing the temperature generated by the rotary air joint during high-speed rotation, thereby extending the service life of the rotary air joint and reducing the cost of use.
