Description

Technical Field

[0001] The utility model relates to the technical field of chromatographs, in particular to a gas chromatograph used for measuring the content of a dephenolizing agent in gas. Background Art

[0002] A gas chromatograph is an efficient and accurate instrument used to analyze components in gases and volatile liquids. In applications involving the determination of dephenolizing agents in gases, a gas chromatograph can accurately detect the dephenolizing agent content in gas samples through its high sensitivity and high resolution. By selecting an appropriate chromatographic column and setting appropriate operating conditions, a gas chromatograph can effectively separate the dephenolizing agent from other components in a gas sample, enabling high-resolution determination.

[0003] Traditional chromatographs commonly use a hook-type installation method to install columns, suspending them within the main structure. However, this installation method is significantly unstable. Due to the inherent fragility of the column, even the slightest loosening of the hook or improper operation can damage the column. Furthermore, the hook installation process is quite cumbersome, requiring the individual alignment and installation of multiple hooks, which is not only time-consuming but also inefficient. This installation method not only increases operational complexity but also potentially increases the risk of column damage.

[0004] Therefore, it is urgent to provide a gas chromatograph for measuring the content of dephenolizing agent in gas to solve the above problems. Utility Model Content

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a gas chromatograph for determining the content of a dephenolizing agent in a gas, comprising a chromatograph body, wherein a chromatographic column is arranged in the chromatograph body.

[0007] In order to solve the problem of cumbersome operation of replacing chromatographic columns in existing chromatographs, a base is provided in the chromatograph body, a sliding cavity is provided in the base, and a plurality of positioning assemblies for positioning the mounting cylinder assembly are provided in the sliding cavity.

[0032] See also Figure 1 As shown, the purpose of this embodiment is to provide a gas chromatograph for measuring the content of dephenolizing agent in gas, including a chromatograph body 1, in which a chromatographic column 2 is arranged.

[0033] For further information, see Figure 2-Figure 4As shown, a base 6 is provided in the chromatograph body 1, and a sliding cavity is provided in the base 6. A plurality of positioning assemblies 9 for positioning the mounting cylinder assembly 5 are provided in the sliding cavity. The mounting cylinder assembly 5 slides in the sliding cavity through the mounting rod 3. A first spring 8 is sleeved on the mounting rod 3. One end of the first spring 8 is fixedly connected to the base 6, and the other end is fixedly connected to the disassembly assembly 4. The disassembly assembly 4 is rotatably connected to the mounting cylinder assembly 5.

[0034] The mounting cylinder assembly 5 is provided with a plurality of clamping assemblies 7 for clamping the chromatographic column 2;

[0035] The clamping assembly 7 includes a support rod 71 arranged on the base 6, and a clamping rod 72 is slidably connected to the support rod 71. A guide groove 73 is provided in the clamping rod 72, and the clamping rod 72 slides on the support rod 71 through the guide groove 73. One end of the clamping rod 72 is rotatably connected to the mounting cylinder assembly 5, and the other end is provided with a hook for clamping the chromatographic column 2; the chromatographic column 2 is pushed inward after resting against the mounting seat 51, and then the mounting seat 51 slides in the sliding cavity of the base 6, and the sliding of the mounting seat 51 drives the several clamping rods 72 thereon to move, and then the clamping rods 72 slide on the support rod 71 through the guide groove 73 thereon until the clamping rod 72 is in a horizontal state, and then the several clamping rods 72 can clamp the chromatographic columns 2 in the several clamping rods 72, and a limited hook is provided on the end of the clamping rod 72 to prevent the chromatographic column 2 from falling off and moving.

[0036] For further information, see Figure 5 As shown, the positioning assembly 9 includes a positioning cylinder 91 fixedly connected to the sliding cavity of the base 6, and a positioning block 92 is slidably connected in the positioning cylinder 91. One end of the positioning block 92 located in the positioning cylinder 91 is fixedly connected to one end of the second spring 93, and the other end of the second spring 93 is fixedly connected to the inner wall of the positioning cylinder 91; the positioning block 92 on the base 6 is just stuck in the positioning slot 52 on the mounting seat 51.

[0037] For details, please refer to Figure 3-Figure 4 As shown, the mounting cylinder assembly 5 includes a mounting seat 51 , which is slidably connected to the base 6 , and a positioning slot 52 matching the positioning block 92 is provided on the mounting seat 51 .

[0038] For further information, see Figure 3-Figure 4As shown, the dismounting assembly 4 comprises a rotating rod 41, which is rotationally connected with the mounting seat 51. One end of the rotating rod 41 is fixedly connected with a rotating seat 42, and the rotating seat 42 is fixedly connected with a dismounting block 43 for sliding in the positioning sliding groove 52. The rotating rod 41 is rotated, thereby driving the rotating seat 42 to rotate, and thereby driving the dismounting block 43 on the rotating seat 42 to slide along the positioning sliding groove 52 on the mounting seat 51 until the dismounting block 43 abuts against the positioning block 92 to be clamped into the positioning cylinder 91. At this time, the positioning of the mounting seat 51 is released, and under the elastic force of the first spring 8, the mounting seat 51 slides out along the sliding cavity, thereby making the clamping rods 72 from the horizontal state to the inclined state, and thereby disengaging the clamping chromatographic column 2.

[0039] In addition, referring to Figure 3 and Figure 4 As shown, the dismounting block 43 is wedge-shaped at both ends, for pushing the positioning block 92 into the positioning cylinder 91.

[0040] The specific working principle is as follows:

[0041] When the chromatographic column 2 is installed, the chromatographic column 2 is aligned with the rotating rod 41 and inserted, and after the chromatographic column 2 abuts against the mounting seat 51, it is continuously pushed in. Then the mounting seat 51 slides in the sliding cavity of the base 6, and the sliding of the mounting seat 51 drives the movement of the clamping rods 72 thereon, and thereby the clamping rods 72 slide on the support rod 71 through the guide groove 73 thereon, until the clamping rods 72 are in the horizontal state, and thereby the clamping rods 72 can clamp the chromatographic column 2 in the clamping rods 72, and the limit hook provided at the end of the clamping rod 72 prevents the chromatographic column 2 from falling off and moving. At this time, the positioning block 92 on the base 6 is clamped into the positioning sliding groove 52 on the mounting seat 51, and the entire installation is completed. When dismounting is needed, the rotating rod 41 is only rotated, thereby driving the rotating seat 42 to rotate, and thereby making the dismounting block 43 on the rotating seat 42 slide along the positioning sliding groove 52 on the mounting seat 51 until the dismounting block 43 abuts against the positioning block 92 to be clamped into the positioning cylinder 91. At this time, the positioning of the mounting seat 51 is released, and under the elastic force of the first spring 8, the mounting seat 51 slides out along the sliding cavity, thereby making the clamping rods 72 from the horizontal state to the inclined state, and thereby disengaging the clamping chromatographic column 2, and the chromatographic column 2 can be pulled out to complete the dismounting. Thus, the problem of complicated operation of replacing the chromatographic column 2 in the existing chromatograph is effectively solved.
