Description

Technical Field

[0001] This utility model relates to the field of liquid chromatography technology, and in particular to a chromatography column oven. Background Technology

[0002] A column oven is a specialized device for precisely controlling the temperature of a chromatographic column. It is a key auxiliary component in gas chromatography and high-performance liquid chromatography systems. Its core function is to stabilize the column temperature and eliminate the interference of ambient temperature fluctuations on the separation effect, thereby improving the repeatability and accuracy of analytical results.

[0003] Chinese Patent Publication No. CN207675713U, published on 20180713, discloses a column oven for a chromatographic column, which includes a chamber, a heating device, and a blowing device. The chamber contains a column loading chamber for loading the chromatographic column. The heating device is mounted on the chamber and is used to heat the surrounding air. The blowing device is mounted on the chamber and is used to blow the heated air into the column loading chamber.

[0004] Existing column ovens typically consist of a housing, a column, a heat-conducting assembly, and upper and lower connecting pipes that connect to the vertical sides of the column. In practice, these connecting pipes pass through the integrated housing and are inserted into the column, making it inconvenient to disassemble and reassemble them independently. Therefore, there is an urgent need to develop a suitable column oven to address these issues. Utility Model Content

[0005] The purpose of this invention is to provide a chromatography column oven to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A chromatography column oven includes a main body, which comprises a chamber, a chromatography column, a heat-conducting assembly, an upper connecting pipe, and a lower connecting pipe. The chromatography column is detachably connected to the inner wall of the chamber. Two sets of telescopic plates and a fixing assembly for fixing the two sets of telescopic plates are integrated on the outer side of the chamber. A side plate connects the two sets of telescopic plates, and corresponding notches are provided between the two sets of telescopic plates and the chamber.

[0008] Preferably, limit strips are fixedly connected to the opposite surfaces of the two sets of telescopic plates, and the two sets of limit strips are slidably connected to the inner surface of the two sets of side plates through two sets of constriction grooves.

[0009] Preferably, the fixing component includes a frame that is fixedly connected to the outer wall of the telescopic plate, and the frame is fixedly connected to the outer wall of the box body via a fixing rod.

[0010] Preferably, the side plate has multiple sets of mesh ports in the middle, and the multiple sets of mesh ports are arranged in a rectangular shape.

[0011] Preferably, the heat-conducting component has a side plate integrated on its outer side, and the side plate is fixedly connected to the outer wall of the housing by a fastening rod.

[0012] Preferably, the outer wall of the chromatographic column is fixedly connected to an outer frame, and the outer frame is fixedly connected to the inner wall of the chamber via a locking rod.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the heat-conducting component generates a hot airflow, and the mesh opening is used to ensure the communication between the chamber and the outside air, facilitating the discharge of cold air. By rotating the fixing rod on the upper telescopic plate to separate it from the outside of the chamber, the upper telescopic plate can be moved down into the side plate. At this time, an open gap appears between the side plate and the chamber, through which the operator can independently disassemble and assemble the upper connecting pipe. Similarly, after independently separating the lower telescopic plate, the lower connecting pipe can be independently disassembled and assembled. After simultaneously separating the fixing rods on both sets of telescopic plates, the side plate can be completely separated from the chamber, allowing for convenient disassembly and assembly of the chromatographic column. This improves the ease of use of the chromatographic column oven without affecting the maintenance of the chromatographic column temperature.

[0015] 2. In this application, limiting strips are fixed on the opposite sides of the two sets of telescopic plates. This can prevent the two sets of telescopic plates from separating from the side plates, and ensure that the position of the side plates remains stable after the two sets of telescopic plates are fixed, thus preventing vertical sliding and improving the stability of the chromatographic column oven.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A chromatography column oven includes a column oven body 1, which includes a box body 101, a chromatography column 102, a heat conduction component 103, an upper connecting pipe 104 and a lower connecting pipe 105. The chromatography column 102 is detachably connected to the inner wall of the box body 101. Two sets of telescopic plates 6 and a fixing component for fixing the two sets of telescopic plates 6 are integrated on the outer side of the box body 101. A side plate 4 is connected between the two sets of telescopic plates 6. Corresponding notches 10 are opened between the two sets of telescopic plates 6 and the box body 101.

[0025] The heat-conducting component 103 generates a hot airflow, and the mesh opening 5 is used to ensure the communication between the chamber 101 and the outside air, facilitating the discharge of cold air. By rotating the fixing rod 8 on the upper telescopic plate 6 to separate it from the outside of the chamber 101, the upper telescopic plate 6 can be moved down into the side plate 4. At this time, an open gap appears between the side plate 4 and the chamber 101, through which the operator can independently disassemble and assemble the upper pipe 104. Similarly, after independently separating the lower telescopic plate 6, the lower pipe 105 can be independently disassembled and assembled. After simultaneously separating the fixing rods 8 on both sets of telescopic plates 6, the side plate 4 can be completely separated from the chamber 101, at which point the chromatography column 102 can be easily disassembled and assembled. This improves the ease of use of the chromatography column oven without affecting the maintenance of the temperature of the chromatography column 102.

[0026] Specifically, such as Figure 2 and Figure 4As shown, limiting strips 11 are fixedly connected to the opposite surfaces of the two sets of telescopic plates 6. The two sets of limiting strips 11 are slidably connected to the inner walls of the two sets of side plates 4 through two sets of constriction grooves. By fixing the limiting strips 11 to the opposite surfaces of the two sets of telescopic plates 6, the separation of the two sets of telescopic plates 6 from the side plates 4 can be avoided. At the same time, it can be ensured that the position of the side plates 4 remains stable after the two sets of telescopic plates 6 are fixed, and vertical sliding is avoided, thereby improving the stability of the chromatography column oven.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the fixing assembly includes a bracket 7 fixedly connected to the outer wall of the telescopic plate 6, and the bracket 7 is fixedly connected to the outer wall of the box 101 via a fixing rod 8, ensuring the ease of disassembly and assembly of the telescopic plate 6 and the outer wall of the box 101. The side plate 4 has multiple sets of mesh openings 5 ​​in the middle, and the multiple sets of mesh openings 5 ​​are rectangularly distributed. The mesh openings 5 ​​are used to ensure the communication between the box 101 and the outside air, facilitating the exhaust of cold air. The heat conduction assembly 103 has a side plate 9 integrated on its outer side, and the side plate 9 is fixedly connected to the outer wall of the box 101 via a fastening rod, facilitating the subsequent disassembly and maintenance of the heat conduction assembly 103. The chromatographic column 102 has an outer frame 2 fixedly connected to its outer wall, and the outer frame 2 is fixedly connected to the inner wall of the box 101 via a locking rod 3, ensuring the ease of independent disassembly and assembly of the chromatographic column 102.

[0028] Working principle: The heat-conducting component 103 generates hot airflow. The mesh opening 5 ensures the connectivity between the housing 101 and the outside air, facilitating the discharge of cold air. Rotating the fixing rod 8 on the upper telescopic plate 6 separates it from the outside of the housing 101, allowing the upper telescopic plate 6 to be moved down into the side plate 4. At this point, an open gap appears between the side plate 4 and the housing 101, allowing the operator to independently disassemble and assemble the upper connecting pipe 104. Similarly, after independently separating the lower telescopic plate 6, the lower connecting pipe 105 can be independently disassembled and assembled. Simultaneously separating both sets... After the fixing rod 8 on the telescopic plate 6 is removed, the side plate 4 can be separated from the box body 101 as a whole. At this time, the chromatographic column 102 can be easily disassembled and assembled. This improves the convenience of using the chromatographic column temperature oven without affecting the temperature maintenance of the chromatographic column 102. The limiting strips 11 are fixed on the opposite sides of the two sets of telescopic plates 6 to prevent the two sets of telescopic plates 6 from separating from the side plate 4. This ensures that the position of the side plate 4 remains stable after the two sets of telescopic plates 6 are fixed, preventing it from sliding vertically, thereby improving the stability of the chromatographic column temperature oven.

[0029] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
