Referring to fig. 1 to 4, the present embodiment provides an inert gas tank for an ultra-high temperature electric heating element.
In this embodiment, the inert gas box comprises a box body 1, and an inlet and an outlet are arranged on one side of the box body 1 for putting in and taking out the electric heating element. In order to realize the sealing of the box body 1, a flange 2 cover is arranged at the inlet and outlet, the connection between the flange 2 cover and the box body 1 is realized through a fastener 6, and a sealing ring is arranged between the flange 2 cover and the box body 1 so as to ensure the sealing of the inert gas box. At least one exhaust port 7 is provided in the casing 1 for exhausting air in the casing 1. An inert gas inlet 5 is arranged on the flange 2 cover, and the inert gas inlet 5 can be connected with an inert gas source for injecting inert gas into the box body 1.
In this embodiment, the whole case 1 may have a rectangular structure or a cylindrical structure, and may be selected according to the production requirements. The exhaust port 7 is provided at the top of the case 1, and the exhaust port 7 is provided with a sealing member, and when the air in the case 1 is exhausted, the exhaust port 7 is sealed by the sealing member, thereby ensuring that the inert gas in the case 1 does not leak. The box body 1 is fully sealed by adopting continuous welding, so that inert gas is ensured not to leak, and the inert atmosphere in the box body 1 is maintained. The selected sealing ring is a silicon rubber sealing ring, and the silicon rubber can bear the temperature of 200 ℃, so that the sealing performance of the silicon rubber sealing ring is not affected even if the heat of the electric heating element leaks out to raise the temperature in the box body 1.
In this embodiment, an inert gas inlet 5 is provided on the cover of the flange 2, for injecting inert gas into the box 1, and the inert gas inlet 5 adopts a pagoda interface. The inert gas commonly used in engineering is argon, and the density of the argon is greater than that of air, so that the inert gas inlet 5 is arranged at the bottom of the flange 2 cover, and the argon enters from the bottom of the box body 1, so that the speed of exhausting air is improved. An observation window 3 is arranged on the flange 2 cover to observe the working condition of the electric heating element in the box body 1, and in the embodiment, the observation window 3 is a flange 2 sight glass. A power interface 4 is arranged on the flange 2 cover and is used for installing a power penetrating piece to provide power for the electric heating element. The flange 2 cover and the box body 1 are provided with handles 8, which are convenient for carrying the inert gas box.
The using method comprises the following steps: 1. opening a flange 2 cover of the inert gas box, putting the ultra-high temperature electric heating element 2 and connecting a power line of the electric heating element; 3. closing the flange 2 cover, and screwing the fastener 6; 4. opening the exhaust port 7 to seal the screw plug; 5. an inert gas inlet 5 is connected with an argon bottle; 6. opening an argon bottle to fill argon into the box body 1 for exhausting air (because the density of the argon is greater than the air density, the argon firstly fills the bottom of the box body 1 after entering the box body 1 until the air in the box body 1 is completely exhausted), and realizing the inert atmosphere of the box body 1 when the box body 1 is completely filled with the argon; 7. the electric heating element is started to work normally by switching on the power supply, so that the electric heating element and oxygen can be effectively isolated, and the ultra-high temperature electric heating element is protected.
The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
