By setting the nozzle 28, the sprayed refrigerant is fan-shaped, so that the cooling of the film is more uniform.

[0051] like Fig.10 As shown, as an optimization of the embodiment, considering the stability of the support of the cross tube 26, a first support frame 33 is installed between the cross tube 26 and the liquid inlet pipe 13, and a first support frame 33 is installed between the cross tube 26 and the liquid outlet pipe 24; the first support frame 33 includes a first support rod 34, and the upper and lower ends of the first support rod 34 are connected with a first C-type seat 35, and the first C-type seat 35 is fixed with a second C-type seat 37 by a first connecting bolt 36.

By setting the first support frame 33, the stability of the cross tube 26 can be improved to ensure the stable spraying of the refrigerant.

[0052] like Figures 11 to 13As shown, as an optimization of the embodiment, considering that too high a refrigerant level in the drum 1 will affect the thickness of the rubber film and increase the rotational torque of the drum 1, a valve stem 38 is slidably connected to the first plug 18, and a valve core 39 is connected to the upper end of the valve stem 38. The upper end of the valve core 39 is spherical, and the side wall of the valve core 39 is slidably adapted to the first branch pipe 17. A rubber ring 40 is connected to the upper side wall of the valve core 39, and the rubber ring 40 is used to close the first branch pipe 17 located above. The lower side wall of the valve core 39 is connected to an O-type The sealing ring 41, the O-ring 41 can prevent the refrigerant from entering the first branch pipe 17 at the lower side; the lower end of the valve stem 38 is connected to a stopper 42, and the side wall of the valve stem 38 is sleeved with a first spring 43, and the first spring 43 is elastically connected between the first plug 18 and the stopper 42.

The float 53 can be adjusted by setting the threaded tube 52. The height of the refrigerant is controlled thereby. When the refrigerant level in the drum 1 rises, the float 53 rises, the height-adjusting rod 51 pushes the push plate 49 upward, the first spring 43 contracts, the valve core 39 is inserted into the first branch pipe 17 on the upper side, the liquid inlet pipe 13 is closed, and the liquid suction pipe 22 is still working.

By arranging the guide rail 45 and the shaft rod 47, the float 53 can adapt to different liquid level conditions and has better flexibility.

[0053] like Fig.14 and Fig.15 As shown, as an optimization of the embodiment, considering that the pressure in the drum 1 increases after the refrigerant is vaporized, if the suction pipe 22 cannot discharge the refrigerant in the drum 1 in time, there is a safety hazard of explosion.
