Abstract
Description
Technical Field
[0001] The present application relates to the field of inert gas air curtain protection devices, and in particular to a nitrogen filling device for filling. Background Art
[0002] After the filling of vials and ampoules is completed, inert gas needs to be filled into the bottles for protection. In the prior art, the nitrogen filling process after filling is completed enters the vials and ampoules through the filling needle, stays in the container and fills with nitrogen, and leaves the container after the nitrogen filling is completed. During this nitrogen filling process, the filling needle will bring in external air when entering and leaving the container, and it is impossible to achieve continuous nitrogen filling after liquid filling. Utility Model Content
[0003] In order to improve the problem of being unable to achieve continuous nitrogen filling after liquid filling, the present application provides a nitrogen filling device for filling.
[0004] The present application provides a nitrogen filling device for filling, which adopts the following technical solution:
[0005] A nitrogen filling device for filling comprises: a nitrogen air curtain cover and a filling pipeline, wherein the filling pipeline is arranged on a lifting device, the nitrogen air curtain cover is arranged below the filling pipeline, the nitrogen air curtain cover is provided with a through hole for the filling pipeline to pass through, the nitrogen air curtain cover is also provided with a nitrogen inlet and a moving groove, the nitrogen inlet is connected to the moving groove, and the through hole is connected to the moving groove.
[0006] In one embodiment, the lifting device includes an elevator and a pipe mounting frame, and the pipe mounting frame fixes a plurality of filling pipes.
[0007] The nitrogen filling device for filling provided in the embodiment of the present disclosure can achieve the following technical effects:
[0008] Nitrogen is continuously injected into the moving tank through the nitrogen inlet, so that the mouth of the ampoule in the moving tank is continuously protected by nitrogen, thereby achieving continuous nitrogen filling after liquid filling, and also helping to avoid the introduction of external air into and out of the ampoule during the filling pipeline.
[0009] The above general description and the following description are exemplary and explanatory only and are not intended to limit the present application. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a structural schematic diagram of a nitrogen filling device for filling provided in an embodiment of the present application.
[0011] Explanation of the reference numerals: 1. nitrogen air curtain cover; 2. filling pipe; 3. elevator; 4. pipe mounting frame; 5. through hole; 6. nitrogen inlet; 7. moving groove; 8. orbital disc. DETAILED DESCRIPTION
[0012] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0013] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.
[0014] The following is combined with Figure 1 This application is described in further detail.
[0015] A nitrogen filling device for filling comprises: a nitrogen air curtain cover 1 and a filling pipeline 2, wherein the filling pipeline 2 is arranged on a lifting device, the nitrogen air curtain cover 1 is arranged below the filling pipeline 2, the nitrogen air curtain cover 1 is provided with a through hole 5 for the filling pipeline 2 to pass through, the nitrogen air curtain cover 1 is also provided with a nitrogen inlet 6 and a moving groove 7, the nitrogen inlet 6 is connected to the moving groove 7, and the through hole 5 is connected to the moving groove 7.
[0016] In one embodiment, the lifting device includes a lift 3 and a pipe mounting frame 4 , and the pipe mounting frame fixes a plurality of filling pipes 2 .
[0017] In one embodiment, a circular rotating disk 8 is provided below the nitrogen air curtain cover 1, and a plurality of ampoules to be filled are provided around the circular rotating disk 8. The corresponding nitrogen air curtain cover 1 and the pipeline mounting frame 4 are both arc-shaped, and the arc corresponds to the arc of the ampoules. The filling pipeline 2 is connected to the nitrogen filling device and the vacuum extraction device through a solenoid valve, and the nitrogen filling or vacuum extraction mode is switched through the solenoid valve.
[0018] In this embodiment, when the rotary table 8 rotates so that the ampoule bottle moves into the moving groove 7 and the mouth of the ampoule bottle is located directly below the through hole 5, the elevator 3 drives the pipe mounting frame 4 to move downward to the filling pipe 2 to enter the inside of the ampoule bottle, and then the canning pipe first evacuates the ampoule bottle to a vacuum, and then fills the ampoule bottle with nitrogen. After the nitrogen filling is completed, the elevator 3 drives the pipe mounting frame 4 to move upward and drives the filling pipe 2 to leave the ampoule bottle. During this process, nitrogen is continuously injected into the moving groove 7 through the nitrogen inlet 6, so that the mouth of the ampoule bottle in the moving groove 7 is continuously protected by nitrogen, thereby realizing continuous nitrogen filling after liquid filling, and also helping to prevent the canning pipe from bringing in external air during the process of entering and leaving the ampoule bottle.
[0019] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
