[0024] The following is a detailed explanation and description of the metal sealed container drying device provided by this utility model after leak testing, with reference to the accompanying drawings.

[0025] This embodiment specifically discloses a drying device for a sealed metal container after leak testing (hereinafter referred to as the drying device), such as... Figure 1-3 As shown, it includes a cylinder 1, an air-guiding mechanism 2, and a heating mechanism 3. The cylinder 1 has an open top and bottom structure. The air-guiding mechanism 2 is located at the top of the cylinder 1 and is used to introduce airflow into the cylinder 1. The air outlet of the air-guiding mechanism 2 can extend into the cylinder. The heating mechanism 3 is located inside the cylinder 1 and is used to heat the airflow inside the cylinder. One or more exhaust ports 11 are provided on the side of the cylinder 1 to discharge the heated airflow to the outside of the cylinder 1.

[0026] In use, the drying device of this application is placed inside a sealed metal container. The air intake mechanism 2 and the heating mechanism 3 are turned on. The air intake mechanism 2 introduces airflow into the cylinder 1, and the heating mechanism 3 heats the airflow. The heated airflow exits the cylinder 1 through the bottom outlet and exhaust port 11, and enters the space between the cylinder 1 and the sealed metal container to dry the moisture inside the sealed metal container. The airflow after heat exchange flows out from the top of the gap between the sealed metal container and the cylinder 1. Due to the fluidity of the gas, there are no dead corners inside the sealed metal container, which can completely dry the moisture inside the sealed metal container without leaving any moisture, thus preventing the sealed metal container from rusting. Compared with wiping with a cloth, this method is more efficient.

[0027] Optionally, a louver 4 is installed inside the exhaust port 11 of the cylinder 1, and a switch 41 is fixed on the cylinder 1. The switch 41 is used to control the angle of the louver 4. The louver 4 can control the speed at which the airflow flows from the inside of the cylinder 1 to the outside, thereby allowing the airflow to be heated to a higher temperature before being discharged from the cylinder 1, thus accelerating the drying speed. The switch 41 can control the angle of the louver 4, thereby controlling the speed at which the air is exhausted from the inside of the cylinder 1. In this embodiment, the switch 41 is a manual switch, such as a knob, which can be used to adjust the angle by linking the louvers with a gear set or linkage. Figure 1 As shown, switch 41 is located on the outer wall of cylinder 1 for easy adjustment.

[0028] When multiple exhaust vents 11 are provided on the cylinder 1, multiple louvers 4 are provided accordingly. All louvers 4 can have their blade angles controlled by a single switch 41, or each louver 4 can have its blade angles controlled by a separate switch 41. This application does not make any specific limitations, as long as it is easy to operate.

[0029] Optionally, multiple exhaust ports 11 are evenly distributed along the circumference of the cylinder 1. These multiple exhaust ports 11 accelerate the drying process, and their even distribution ensures uniform airflow from multiple directions, further accelerating the drying efficiency. Preferably, as follows... Figure 2 As shown, the cylinder 1 has four exhaust vents 11, which exhaust hot air from four directions.

[0030] Optional, such as Figure 1 As shown, the heating mechanism 3 includes a frame 31 and heating wires 32. One or more heating wires 32 are fixed to the frame 31, and the frame 31 is fixedly connected to the cylinder 1. The heating wires 32 can be arranged along the height direction of the cylinder 1, and multiple heating wires 32 can be arranged in parallel, maintaining a distance between them to allow airflow. The frame 31 can be a square frame, and the heating wires 32 are fixed inside the frame 31. The top of the heating wires 32 is fixedly connected to the top of the frame 31, and the bottom of the heating wires 32 is fixedly connected to the bottom of the frame 31.

[0031] Preferably, multiple parallel heating wires 32 are fixed inside the frame 31 to accelerate the airflow heating rate and thus improve drying efficiency.

[0032] Preferably, the heating wire 32 is spiral-shaped to increase the contact area with the airflow and accelerate the airflow heating rate.

[0033] Optionally, the frame 31 can be made of a material with high thermal conductivity, such as metal. The heating wire 32 can also heat the frame 31, and the airflow in contact with the frame 31 can also be heated, thus improving heating efficiency.

[0034] Optionally, the number of heating mechanisms 3 is the same as the number of exhaust vents 11 on the cylinder 1, and they are arranged in a one-to-one correspondence. The heating wire 32 of the heating mechanism 3 is directly opposite the exhaust vent 11, and the air outlet of the induced draft mechanism 2 is located on the side opposite to the heating mechanism 3 and the exhaust vent 11. After the airflow discharged from the air outlet of the induced draft mechanism 2 enters the cylinder 1, it first flows through the heating mechanism 3 and is heated. The heated gas is then discharged from the louvers 4 and enters the space between the cylinder 1 and the metal sealed container to dry the moisture inside the metal sealed container.

[0035] When there is one exhaust port 11 on the cylinder body 1, the heating wire 32 of the heating mechanism 3 is directly opposite the exhaust port 11. The air outlet of the air-guiding mechanism 2 can be set on the side opposite to the heating mechanism 3 and the exhaust port 11. The airflow introduced by the air-guiding mechanism 2 is first heated by the heating wire 32 and then discharged from the cylinder body 1 through the louver 4 in the exhaust port 11.

[0036] When there are two exhaust vents 11 on the cylinder 1, the two exhaust vents 11 are arranged opposite each other, the two louvers 4 are arranged opposite each other, and the corresponding two heating mechanisms 3 are also arranged opposite each other. The two heating mechanisms 3 are kept at a distance. The air outlet of the air-inducing mechanism 2 can be set between the two heating mechanisms 3. The introduced airflow flows to the two heating mechanisms 3 respectively, and after being heated, it is discharged from the cylinder 1 through the two louvers 4 respectively.

[0037] When there are three or more heating mechanisms 3, the frame 31 of the heating mechanism 3 forms a closed shape. The air outlet of the air-expelling mechanism 2 can face the inside of the closed shape formed by the frame 31. The airflow flows to each heating mechanism 3 and is heated, then discharged from the cylinder 1 through the louvers 4. Figure 2 As shown, there are four exhaust vents 11, four louvers 4, and four heating mechanisms 3. The four frames 31 can be connected to form a rectangle, and the air outlet of the air intake mechanism 2 can face the inside of the rectangle.

[0038] Optionally, the induced draft mechanism 2 is an intake fan, such as... Figure 3 As shown, the air intake fan is fixed to the top of the cylinder 1 by a frame. Connecting lugs can be installed on the frame, and these lugs are located at the top of the cylinder 1. Figure 1 As shown, the air outlet of the air inlet fan extends into the inside of the cylinder 1, and the connecting lug can be welded or connected to the cylinder 1 by screws.

[0039] In some alternative embodiments, such as Figure 1 and 3 As shown, a lifting bracket 5 is fixed to the top of the cylinder 1. The lifting bracket 5 can be two opposing lifting rings, which facilitates the overall lifting, placement, and transfer of the drying device.

[0040] The heating wire 32 and the exhaust fan of this application can use mains power as a power source and be connected to the mains power source through a wire.

[0041] The method of using the metal sealed container drying device after leak testing in this embodiment is as follows:

[0042] After leak testing the metal sealed container, drain the leak-testing water from the container. Operate switch 41 to open the louvers 4 to a certain angle, which can be adjusted according to actual needs. After the louvers 4 are open, place the drying device of this embodiment into the metal sealed container. Power on the device to activate the air intake mechanism 2 and the heating mechanism 3. Air is drawn in through the top air intake mechanism 2, and the airflow enters the cylinder 1 and is heated by the heating mechanism 3. The hot airflow is discharged through the louvers 4, drying the inside of the metal sealed container. After working for a period of time, the drying device can be rotated to a certain angle to ensure uniform drying inside the metal sealed container. The operation is simple, more efficient than wiping with a cloth, and saves time and effort.

[0043] Due to the fluidity of the gas, it can enter every corner of the sealed metal container, eliminating dead zones and solving the problem of residual moisture in some areas inside the sealed metal container, thus improving operational efficiency.
