Description
Technical Field

Wherein the high pressure inlet end 31 is provided with a nozzle 311.
Specifically, the operating principle of the vortex tube 3 is as follows:
the compressed gas is delivered into the high-pressure gas inlet end 31, and under the action of the nozzle 311, the high-pressure gas at the high-pressure gas inlet end 31 expands and enters the vortex chamber 35 at a high speed in a tangential direction. The compressed gas rotates in a spiral manner at a high speed in the vortex chamber 35, the temperature of the compressed gas is rapidly increased due to friction with the inner wall surface of the vortex chamber 35 to form high-temperature gas, part of the high-temperature gas is discharged from the hot exhaust end 33, the rest part of the high-temperature gas flows back along the central line and continuously performs heat exchange, so that the temperature is gradually reduced, and finally low-temperature gas is formed and discharged from the cold exhaust end 32.

Further, in the present embodiment, the vortex tube 3 may have a long tubular configuration. Wherein the cold discharge end 32 and the hot discharge end 33 are located at opposite ends of the vortex tube 3, respectively.

Further, the inner bearing plate 42 is provided with a through hole corresponding to the position of the high pressure air inlet end 31, and the high pressure air inlet end 31 is inserted into the through hole for butting the other devices.
Further, in this embodiment, in order to facilitate that the high-temperature gas and the low-temperature gas generated by the vortex tube 3 can directly act on the rotating drum 1, the cold reversing tube 36 and the hot reversing tube 37 are additionally arranged to realize the switching of the propagation paths of the two gases, so as to improve the temperature regulation effect on the rotating drum 1.
Specifically, as a preferred example of the present embodiment, referring to fig. 1, the end of the cold exchanging pipe 36 remote from the cold exhaust end 32 and the end of the hot exchanging pipe 37 remote from the hot exhaust end 33 are symmetrically arranged in the axial direction of the drum 1. That is to say, through above-mentioned setting, can make high-temperature gas and low-temperature gas act on the relative both sides of rotary drum 1 respectively to realize that high-temperature gas carries out the intensification process to rotary drum 1 alone, or gas carries out the cooling process to rotary drum 1 alone in the low temperature, or two kinds of gas carry out the control by temperature change process to the barrel jointly, all can. Therefore, the space layout and the airflow flowing can be facilitated, the mutual crosstalk of two gases can not occur, and the temperature control effect is improved.
Furthermore, the end of the cold exchange tube 36 away from the cold exhaust end 32 and the end of the hot exchange tube 37 away from the hot exhaust end 33 both extend to a position adjacent to the rotating drum 1 through the upper bearing plate 41, and both ends of the cold exchange tube are horn-shaped, so that the diffusion range of the gas can be increased, the temperature control time is shortened, and the temperature control effect is better.

Wherein, a sealed space 51 is formed between the sealing cover 5 and the rotary drum 1, and the end of the cold exchange tube 36 far away from the cold exhaust end 32 and the end of the hot exchange tube 37 far away from the hot exhaust end 33 both extend into the sealed space 51. Therefore, the cold reversing pipe 36 and the hot reversing pipe 37 can directly convey low-temperature gas and high-temperature gas into the sealed space 51, the peripheral diffusion of the low-temperature gas and the high-temperature gas is prevented, energy is saved, and the temperature control effect on the rotary drum 1 is improved, but the utility model is not limited to the above. That is, it is within the scope of the present patent to select whether to use the sealing cover 5 according to the actual use requirement, and the sealing cover 5 may be preferably mounted on the upper carrier plate 41, but not limited thereto.
