DETAILED DESCRIPTION

[0027] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] like Figure 1 As shown, an automatic analysis device for industrial gas filling process includes: a gas tank 1, a processing tank 3 and an analysis module 5, and an impurity removal mechanism 7 arranged in the processing tank 3;

[0029] like Figure 2 As shown, a first conduit 2 is connected to the top of the gas tank 1 and the bottom of the processing tank 3, a second conduit 4 is connected to the top of the processing tank 3 and one side of the analysis module 5, and a guide pipe 6 is connected to the other side of the analysis module 5;

[0030] The impurity removal mechanism 7 includes: a condensation box 8, a plurality of introduction mechanisms 9 arranged on the circumferential outer wall of the condensation box 8, a condensation tube 10 arranged on the circumferential inner wall of the condensation box 8, a plurality of limit rods 705 arranged at the bottom of the condensation box 8, a threaded rod 704 arranged at the bottom of the condensation box 8, and an activated carbon plate 706 arranged on the circumferential outer wall of the condensation box 8.

[0031] The top of the condensation box 8 is fixedly connected to the top inner wall of the treatment tank 3, and the bottom of the treatment tank 3 is fixedly connected with a motor 703. One end of the output shaft of the motor 703 passes through the treatment tank 3 and is fixedly connected to one end of the threaded rod 704. The other end of the threaded rod 704 is rotatably connected to the bottom of the condensation box 8. The activated carbon plate 706 is threadedly connected to the circumferential outer wall of the threaded rod 704, and the circumferential outer wall of the activated carbon plate 706 is tightly fitted with the circumferential inner wall of the treatment tank 3.

[0032] The tops of several limit rods 705 are fixedly connected to the bottom of the condensation box 8, and the bottoms of several limit rods 705 are fixedly connected to the bottom inner wall of the treatment tank 3. Several limit holes 707 are opened on the upper surface of the activated carbon plate 706, and several limit rods 705 are movably connected to the several limit holes 707 respectively. The bottom of the treatment tank 3 is fixedly connected with a protective frame 701, and the circumferential outer wall of the protective frame 701 is opened with several penetrating heat dissipation holes 702. The circumferential outer wall of the condensation box 8 is fixedly connected with several connecting rods 11, and the several connecting rods 11 are fixedly connected to the circumferential inner wall of the treatment tank 3. The circumferential outer wall pipeline of the condensation box 8 is connected with a liquid outlet pipe 12, and the liquid outlet pipe 12 penetrates the treatment tank 3, and the circumferential outer wall of the liquid outlet pipe 12 is provided with a valve.

[0033] It should be noted that the impurity removal mechanism 7 is the core part of the device body, which is responsible for purifying the industrial gas exported from the gas tank 1. The condensation box 8 is the main component for impurity removal. It condenses water vapor and other easily condensable impurities in the gas through the condenser 10. The activated carbon plate 706 removes organic compounds in the industrial gas through adsorption. The limit rod 705 ensures the correct position of the activated carbon plate 706 in the condensation box 8, and the combination of the threaded rod 704 and the motor 703 drives the activated carbon plate 706 to reciprocate up and down to achieve dynamic filtration. The first conduit 2 and the second conduit 4 are respectively connected to the gas tank 1, the processing tank 3 and the analysis module 5, forming a channel for the flow of industrial gas. The industrial gas is first introduced from the gas tank 1 to the processing tank 3 through the first conduit 2. After being purified by the impurity removal mechanism 7 in the processing tank 3, it enters the analysis module 5 through the second conduit 4 for component analysis. The export pipe 6 is used to export the analyzed gas;

[0034] The analysis module 5 includes an infrared sensor, an electrochemical sensor, a mass spectrometer, and a gas chromatograph for detecting the composition and concentration of industrial gases, and can perform quantitative analysis on the composition of industrial gases.

[0035] like Figure 1-Figure 3 As shown, the introduction mechanism 9 includes: an introduction tube 901, a movable groove 904 is opened on one side of the introduction tube 901, a piston 908 is slidably connected in the movable groove 904, a plurality of fixed rods 906 are fixedly connected to the circumferential inner wall of the movable groove 904, a same fixed ring 905 is fixedly connected between the plurality of fixed rods 906, a compression spring 907 is fixedly connected to one side of the fixed ring 905, and the other side of the compression spring 907 is fixedly connected to one side of the piston 908;

[0036] The circumferential inner wall of the movable groove 904 is provided with a plurality of flow grooves 903, one end of the piston 908 is clamped with one end of the movable groove 904, a rubber ring 902 is fixedly connected to one side of the piston 908, and the circumferential outer wall of the condensation box 8 is provided with a plurality of penetrating through holes, and the inlet pipe 901 is fixedly connected to the through holes.

[0037] It should be noted that the introduction mechanism 9 controls the flow of gas by the sliding movement of the piston 908 in the movable groove 904. The movement of the piston 908 is guided by the structure composed of the fixed rod 906 and the fixed ring 905, which ensures the stability and precise position of the piston 908. The extrusion spring 907 provides the necessary extrusion force so that the piston 908 can be tightly engaged with the edge of the movable groove 904, thereby closing the flow of industrial gas when necessary. The rubber ring 902 on the piston 908 plays a sealing role to prevent gas leakage when the piston 908 moves. The design of the circulation groove 903 allows industrial gas to pass through when the piston 908 is not completely closed.

[0038] When the utility model is used, the industrial gas is introduced into the processing tank 3 through the first conduit 2, and the motor 703 at the bottom of the processing tank 3 drives the activated carbon plate 706 to reciprocate up and down in the processing tank 3 through the threaded rod 704. When the industrial gas is introduced into the processing tank 3 through the first conduit 2, the industrial gas is squeezed by the activated carbon plate 706 descending, which increases the density and time of contact between the industrial gas and the activated carbon plate 706, thereby improving the filtering effect. When the activated carbon plate 706 rises, the filtered industrial gas is introduced into the condensation box 8 through the introduction pipe 901. During the introduction, the industrial gas The gas is squeezed by the activated carbon plate 706, so that the piston 908 is squeezed, and the industrial gas flows into the condensation box 8 through a number of flow grooves 903. When the activated carbon plate 706 descends, the air pressure decreases, and the piston 908 is clamped with one end of the introduction pipe 901 by the squeezing force of the squeezing spring 907, so as to prevent the industrial gas introduced into the condensation box 8 from flowing out. The industrial gas in the condensation box 8 condenses water vapor and other easily condensable impurities in the gas through the condensation pipe 10. The treated industrial gas enters the analysis module 5 through the second conduit 4 for component analysis, and the outlet pipe 6 is used to export the analyzed gas.

[0039] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
