Description

Technical Field

[0001] This utility model relates to the field of chromatography analyzer technology, specifically to an adsorption device for a chromatography analyzer. Background Technology

[0002] A chromatographic analyzer is a precision instrument that separates and analyzes components in a mixture by utilizing the differences in the distribution between the stationary and mobile phases. Its core principle lies in the differences in the adsorption, dissolution, or distribution behavior of different substances between the two phases, causing them to migrate at different speeds within the chromatographic column, ultimately achieving separation and detection. During the use of a chromatographic analyzer, adsorption devices are used to separate materials in order to achieve the separation of mixtures and facilitate the testing of individual components.

[0003] Adsorption devices, during operation, separate the target analyte by adsorbing the corresponding components within the chromatographic column. However, existing adsorption devices suffer from drawbacks: the column cannot be quickly replaced, and the sealing of the column connections is difficult to guarantee. Therefore, an adsorption device for a chromatographic analyzer is proposed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide an adsorption device for a chromatographic analyzer, so as to solve the problems mentioned in the background art, that existing adsorption devices are inconvenient to quickly replace the chromatographic column during use, and are inconvenient to effectively ensure the sealing of the chromatographic column connection end.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adsorption device for a chromatographic analyzer, comprising an adsorption tube filled with an adsorbent, an inlet pipe inserted at the upper end of the adsorption tube, and an outlet pipe inserted at the lower end of the adsorption tube, an operating platform below the adsorption tube, and a support plate on the upper surface of the operating platform, multiple sets of fixing plates respectively provided on the support plate, and connecting blocks inserted between the fixing plates, hollow blocks embedded in both sides of the connecting blocks, and elastic limiting blocks inserted inside the hollow blocks, with springs inside the hollow blocks, and the other end of the springs connected to the elastic limiting blocks, limiting holes correspondingly opened on the fixing plates, and elastic limiting blocks inserted into the limiting holes, and connecting blocks respectively provided on the adsorption tube;

[0006] The adsorption tube is fitted with rubber sleeves at its upper and lower ends, and fixed blocks are provided on the outer walls of both sides of the upper and lower ends of the adsorption tube. The rubber sleeves are provided with corresponding locking blocks on both sides, and the locking blocks are respectively inserted into the fixed blocks.

[0007] The adsorption tube has threads on its outer wall at the upper and lower ends, and spiral rings are spirally wound on the threads, and the spiral rings are respectively disposed on the protective cover.

[0008] Preferably, the inlet pipe and outlet pipe respectively form a locking and limiting structure with the adsorption pipe.

[0009] Preferably, the connecting blocks are respectively engaged in the limiting holes by hollow blocks, springs, and elastic limiting blocks to form an elastic engaging limiting structure with the fixing plate.

[0010] Preferably, the rubber sleeves are inserted into the fixing block through locking blocks to form a locking and limiting structure with the adsorption tube.

[0011] Preferably, the protective cover forms a spiral locking structure with the adsorption tube via a spiral ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The connecting blocks of the adsorption device of the chromatograph are respectively engaged in the limiting hole through hollow blocks, springs, and elastic limiting blocks, forming an elastic engaging limiting structure with the fixing plate. Thus, the elastic engaging components ensure the support of the adsorption tube while allowing for quick loading and unloading of the adsorption tube, thereby avoiding the need for loading and unloading the adsorption tube by means of screws, which reduces its convenience of use. In addition, the operating table is equipped with two sets of adsorption tubes to ensure that the device can work continuously. The rubber sleeves of the device are respectively inserted into the fixing block through the engaging blocks, forming an engaging limiting structure with the adsorption tube. Thus, the rubber sleeves installed through the engaging blocks effectively ensure the sealing of the connection at both ends of the adsorption tube, thereby ensuring the working effect of the device. The protective cover of the device forms a spiral locking structure with the adsorption tube through a spiral ring. Thus, the spirally installed protective cover prevents the material from splashing onto the hands of the operator when the adsorption tube is disassembled, thus avoiding any impact.

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: an adsorption device for a chromatographic analyzer, including an adsorption tube 1, which is filled with an adsorbent, an inlet tube 2 inserted at the upper end of the adsorption tube 1, and an outlet tube 3 inserted at the lower end of the adsorption tube 1.

[0020] Furthermore, the inlet pipe 2 and the outlet pipe 3 respectively form a locking and limiting structure with the adsorption pipe 1, thereby enabling the device to normally adsorb the internal components of the material through the locking and installing inlet pipe 2 and outlet pipe 3.

[0021] An operating platform 4 is provided below the adsorption tube 1, and a support plate 5 is provided on the upper surface of the operating platform 4. Multiple sets of fixing plates are provided on the support plate 5, and connecting blocks 6 are inserted between the fixing plates. Hollow blocks 7 are embedded in both sides of the connecting blocks 6, and elastic limiting blocks 8 are inserted inside the hollow blocks 7. A spring 9 is provided inside the hollow blocks 7, and the other end of the spring 9 is connected to the elastic limiting block 8. Limiting holes are correspondingly opened on the fixing plates, and the elastic limiting blocks 8 are inserted into the limiting holes. The connecting blocks 6 are respectively provided on the adsorption tube 1.

[0022] Furthermore, the connecting block 6 is engaged with the fixing plate through the hollow block 7, spring 9, and elastic limiting block 8 to form an elastic engagement limiting structure. Thus, the adsorption tube 1 assembly can be quickly installed and removed through the elastic engagement assembly, so as to clean its interior regularly and ensure the stability of the adsorption tube 1 during the placement and operation process.

[0023] The adsorption tube 1 is fitted with rubber sleeves 10 at its upper and lower ends, and the upper and lower ends of the adsorption tube 1 are respectively provided with fixing blocks 12 on the outer walls on both sides. The rubber sleeves 10 are respectively provided with locking blocks 11 on both sides, and the locking blocks 11 are respectively inserted into the fixing blocks 12.

[0024] Furthermore, the rubber sleeve 10 is inserted into the fixing block 12 through the locking block 11 to form a locking and limiting structure with the adsorption tube 1. In this way, the rubber sleeve 10 attached to the connection increases the sealing of both ends of the adsorption tube 1, thereby avoiding the effect of low sealing at the connection affecting the working effect of the device.

[0025] The upper and lower ends of the adsorption tube 1 are respectively provided with threads on the outer wall, and spiral rings 14 are respectively spiraled on the threads, and the spiral rings 14 are respectively provided on the protective cover 13.

[0026] Furthermore, the protective cover 13 forms a spiral locking structure with the adsorption tube 1 through the spiral ring 14, thereby effectively protecting the staff through the spirally installed protective cover 13, and thus avoiding the impact of material splashing on the staff when the feed pipe 2 and the discharge pipe 3 are disassembled.

[0027] Working Principle: In the adsorption device of a chromatograph, the material to be adsorbed is first fed into the adsorption tube 1 through the feed pipe 2. Simultaneously, the rubber sleeve 10, which engages with the fixing block 12, effectively ensures the seal at both ends of the adsorption tube 1, thus guaranteeing its working effect. During use, the rubber sleeve 10 can be periodically moved up and down to allow for periodic replacement. The material in the adsorption tube 1 adsorbs the specified components, and the adsorbed material is transported to the corresponding equipment for testing through the discharge pipe 3. After adsorption tube 1 is used up, it can be used alternately with another set of adsorption tubes 1, ensuring the continuous operation of the device. Meanwhile, the feed pipe 2 and the discharge pipe 3 can be moved up and down to disassemble the adsorption tube 1, which facilitates cleaning of the tube itself and the internal adsorbent. During disassembly, the protective cover 13 can be installed by a screw to prevent material from splashing onto the hands of the workers and causing injury. After disassembly of both ends of the adsorption tube 1, the elastic limiting block 8 can be pressed to retract into the hollow block 7, so that the adsorption tube 1 can be quickly disassembled. This avoids the complexity of loading and unloading the adsorption tube 1 by means of screws, thus ensuring the stability of the adsorption tube 1 during operation and increasing the convenience of loading and unloading. This is the usage process of the adsorption device of the chromatograph.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
