[0023] Reference Figure 1-3 , an embodiment of the present application is proposed, and the automatic drying device for gas cylinders described in this embodiment includes:

[0024] An oven 10, wherein one end of the oven 10 is open;

[0025] A horizontal moving track 30 extends from an open end of the oven 10 into the oven;

[0026] A drying vehicle 40 is installed on the horizontal moving track 30. At least two rotating rollers 50 are provided at the upper end of the drying vehicle 40. The rotating rollers 50 are sequentially spaced and distributed along the moving direction of the horizontal moving track 30. Horizontal gas cylinders 20 are placed on the two rotating rollers 50.

[0027] The driving mechanism 60 is installed on the drying vehicle 40, and is used to drive the rotating roller 50 to drive the gas cylinder 20 placed on the upper end thereof to rotate synchronously.

[0028] In the initial state, the drying vehicle 40 is distributed at one end of the horizontal moving track 30 and is located outside the open side of the oven 10 , and the staff can place a gas cylinder 20 to be dried on the two rotating rollers 50 .

[0029] After the gas cylinders 20 to be dried are loaded, the horizontal moving track 30 drives the drying vehicle 40 to move into the oven 10 .

[0030] After the vacuum pump is connected to the valve of the gas cylinder 20, the oven 10 and the driving mechanism 60 are started. After the oven 10 heats the gas cylinder 20 for a period of time, the vacuum pump is started. The vacuum pump extracts air from the gas cylinder 20. At the same time, the driving mechanism 60 drives the gas cylinder 20 to be dried to rotate synchronously through the rotating roller 50, so that the contact area between the residual water in the gas cylinder 20 and the inner wall of the gas cylinder 20 is increased, which is conducive to increasing the evaporation rate in the gas cylinder 20.

[0031] The oven 10 can completely cover the gas cylinder 20 inside for heating. After drying, the vacuum pump, the valve of the gas cylinder 20 and the driving mechanism 60 are closed, and the horizontal moving track 30 drives the open side of the drying vehicle 40 to move out of the oven 10.

[0032] The horizontal moving track 30 is provided with racks distributed along its length direction, the drying vehicle is provided with a driving source, and the driving source is provided with a gear meshing with the racks, and the driving source drives the gear to rotate so that the drying vehicle 40 moves along the length direction of the horizontal moving track 30 .

[0033] Since the gas cylinder 20 to be dried needs to rotate synchronously with the rotating roller 50, those skilled in the art should know that the vacuum pipe of the vacuum pump described in the present application is connected to the valve of the gas cylinder 20 via a rotating interface, and the gas cylinder 20 to be dried can rotate relative to the vacuum pipe.

[0034] A through hole may also be provided on the side wall of the oven 10 so that a worker can connect the interface of the vacuum pipe with the valve of the gas cylinder 20 through the through hole.

[0035] A door body may also be provided on the open side of the oven 10, so that the oven 10 can close the door body when heating the gas cylinder, thereby reducing heat loss and ensuring heat utilization.

[0036] In this embodiment, a plurality of rotating rollers 50 are provided, and one of every two adjacent transmission rollers is transmission-connected to the driving mechanism 60 .

[0037] A plurality of rotating rollers 50 are provided, so that a plurality of gas cylinders 20 can be placed on the drying vehicle 40. Since the gas cylinders 20 to be dried are supported on two rotating rollers 50, when the gas cylinders 20 need to be driven to rotate synchronously by the rotating rollers 50, only one rotating roller 50 needs to be driven to rotate, which is convenient for installation.

[0038] Based on the above content, the driving mechanism 60 includes a motor 61, a transmission chain, a driving sprocket and a driven sprocket. The motor 61 is installed on the drying car 40, and the driving sprocket is coaxially fixedly installed on the output shaft of the motor 61. A driven sprocket is coaxially fixedly installed at one end of each two adjacent rotating rollers 50, and the transmission chain is wound around the driving sprocket and all the driven sprockets.

[0039] In this embodiment, the motor 61 drives the driving sprocket and drives all the transmission chains to rotate synchronously through the transmission chain, so that all the gas cylinders 20 on the drying vehicle 40 rotate synchronously.

[0040] Preferably, the rotating roller 50 is a heating roller. When the rotating roller 50 rotates on the drying vehicle 40, the rotating roller 50 generates heat and heats the gas cylinder 20. Compared with the oven 10, the rotating roller 50 contacts the outer wall of the gas cylinder 20, which can further improve the heating efficiency of the gas cylinder 20 and is conducive to improving the drying efficiency.

[0041] Based on the above content, further, the rotating roller 50 is provided with a plurality of mounting holes along the circumference of the second conveying roller, and the heating element 70 is respectively installed in each of the mounting holes.

[0042] A conductive ring is coaxially mounted on the rotating roller 50 , and the conductive ring is electrically connected to the plurality of heating elements 70 , so that the rotating roller 50 can be heated by the heating elements 70 while the rotating roller 50 is rotating.

[0043] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
