Description

Technical Field

[0001] This application relates to the field of chromatography and adsorption, and more specifically, to a chromatography and adsorption system for traditional Chinese medicine compound preparations. Background Technology

[0002] Column chromatography is widely used in the field of separation and purification technology. For example, it is often used in the separation and purification of drugs. The principle of column chromatography is that the mixture to be purified and the packing material have a binding and adsorption force. Using an eluent for elution, the components with weak binding force to the packing material will be eluted first, and the components with strong binding force to the packing material will be eluted later, thereby achieving separation.

[0003] Currently, in the process of mixing and purifying using chromatography columns, the packing material inside the column needs to be cleaned after multiple uses. However, the packing material inside traditional chromatography columns is inconvenient to clean and may even adhere to the inner wall, affecting subsequent use. Utility Model Content

[0004] To overcome the above deficiencies, this application provides a chromatographic adsorption system for traditional Chinese medicine compound preparations, which aims to improve the problems mentioned in the background art.

[0005] This application provides a traditional Chinese medicine compound drug chromatography and adsorption system, including a support component and a chromatography component.

[0006] The support assembly includes a base plate, a support rod, and a column. The support rod is fixedly connected to the base plate, and the column is installed on one side of the support rod.

[0007] The chromatography assembly includes a filter plate, a connecting rod, an elastic element, an end cap, a threaded rod, and a piston. The connecting rod is fixedly connected to the filter plate. Both the filter plate and the connecting rod are slidably disposed within the column. The elastic element is disposed at the top of the column. The end cap is threadedly fitted onto the column. The threaded rod is threaded through the end cap. The piston is installed at the bottom end of the threaded rod.

[0008] In one specific implementation, a groove is provided on the inner wall of the column, and the connecting rod is adapted to the groove.

[0009] In the above implementation process, a groove is opened to accommodate the insertion of the connecting rod, and the connecting rod and the inner wall of the column are adapted to each other in curvature.

[0010] In one specific implementation, an arc-shaped plate is provided at the top of the connecting rod, the arc-shaped plate is pressed against the top of the elastic element, and the arc-shaped plate is adapted to the top of the groove.

[0011] In the above implementation process, an arc-shaped plate is set to press on the top of the elastic element. During disassembly, the elastic element is used to lift the arc-shaped plate, making it easy to pull out the connecting rod and filter plate.

[0012] In one specific implementation, the elastic element includes a spring and a push rod, the top end of the column has a groove, the spring is disposed in the groove, and one end of the push rod slides through the groove.

[0013] In the above implementation process, by setting up a spring and a push rod, the elastic restoring effect of the spring pushes the push rod, and the push rod pushes the arc-shaped plate, making it convenient for personnel to remove the arc-shaped plate.

[0014] In one specific implementation, a handwheel is fixedly connected to the end of the threaded rod away from the piston.

[0015] In the above implementation process, by setting up a wheel, it is convenient to drive the threaded rod to rotate by rotating the wheel, which facilitates operation.

[0016] In one specific implementation, a connecting ring is provided on one side of the support rod, and the column is fixedly inserted through the connecting ring.

[0017] In the above implementation process, a connecting ring is set to support the mounting column.

[0018] In one specific implementation, a guide pipe is connected to the bottom end of the column, and a valve is installed on the guide pipe.

[0019] In the above implementation process, a feed pipe and valves are used to control the discharge of the liquid medicine.

[0020] In one specific implementation, a feeding pipe is connected to the side of the column.

[0021] In the above process, a feed tube is opened to add the pre-selected herbal solution or eluent to be chromatographically analyzed.

[0022] Beneficial effects: This application provides a chromatographic adsorption system for traditional Chinese medicine compound preparations. By setting a base plate, support rods, and a column, a stable support mechanism is provided. By setting a filter plate, connecting rod, elastic element, end cap, threaded rod, and piston, during installation, the end cap presses on the top of the connecting rod and squeezes the elastic element. During disassembly, the end cap is removed, and the elastic element lifts the filter plate and connecting rod, thereby facilitating the removal of the filter plate and connecting rod and bringing out the packing material on the filter plate. This makes it easier to clean out the internal packing material and improves practicality. Attached Figure Description

Detailed Implementation

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0032] Please see Figures 1-6 This application provides a traditional Chinese medicine compound chromatographic adsorption system, including a support component 100 and a chromatographic component 200.

[0033] Please see Figure 1 and 2 The support assembly 100 includes a base plate 110, a support rod 120, and a column 130. The support rod 120 is fixedly connected to the base plate 110, and the column 130 is installed on one side of the support rod 120.

[0034] The support rod 120 has a connecting ring 122 on one side, and the column 130 is fixedly inserted through the connecting ring 122. The connecting ring 122 is used to support the installation column 130.

[0035] Specifically, a feed pipe 140 is connected to the bottom end of the column 130, and a valve is installed on the feed pipe 140. The feed pipe 140 and the valve are used to control the discharge of the liquid medicine.

[0036] In one specific implementation, a feed pipe 150 is connected to the side of the column 130. The feed pipe 150 is used to add the pre-treatment solution or eluent to be chromatographically prepared.

[0037] Please see Figure 1 , 3 4, 5, and 6, the chromatography assembly 200 includes a filter plate 210, a connecting rod 220, an elastic element 240, an end cap 250, a threaded rod 260, and a piston 270. The connecting rod 220 is fixedly connected to the filter plate 210. Both the filter plate 210 and the connecting rod 220 are slidably disposed within the column 130. The elastic element 240 is disposed at the top of the column 130. The end cap 250 is threadedly sleeved onto the column 130. The threaded rod 260 is threaded through the end cap 250. The piston 270 is installed at the bottom end of the threaded rod 260.

[0038] The inner wall of the column 130 is provided with a groove 131, and the connecting rod 220 is adapted to the groove 131. The groove 131 is provided to accommodate the insertion of the connecting rod 220, and the connecting rod 220 and the inner wall of the column 130 are adapted to each other in curvature.

[0039] The connecting rod 220 has an arc-shaped plate 221 at its top end. The arc-shaped plate 221 presses against the top end of the elastic member 240, and the arc-shaped plate 221 is compatible with the top of the slide groove 131. By setting the arc-shaped plate 221, it is used to press against the top end of the elastic member 240. When disassembling, the elastic member 240 is used to lift the arc-shaped plate 221, so that the connecting rod 220 and the filter plate 210 can be pulled out.

[0040] Specifically, the elastic element 240 includes a spring 241 and a push rod 242. A groove 132 is provided at the top of the column 130, and the spring 241 is disposed in the groove 132. One end of the push rod 242 slides through the groove 132. By setting the spring 241 and the push rod 242, the elastic recovery of the spring 241 pushes the push rod 242, and the push rod 242 pushes the arc-shaped plate 221, making it convenient for personnel to remove the arc-shaped plate 221.

[0041] In this embodiment, a handwheel 261 is fixedly connected to the end of the threaded rod 260 away from the piston 270. By setting the handwheel 261, it is convenient to rotate the threaded rod 260 by rotating the handwheel 261, which facilitates operation.

[0042] The working principle of this traditional Chinese medicine compound chromatographic adsorption system is as follows: During use, the packing material is placed on the filter plate 210, and the end cap 250 is threaded onto the column 130. The end cap 250 presses against the arc-shaped plate 221, which in turn presses against the top rod 242, which in turn presses against the spring 241. When it is necessary to remove the adsorption packing material, the end cap 250 is rotated to open it. The elastic recovery of the spring 241 pushes the arc-shaped plate 221, which in turn moves the connecting rod 220. The connecting rod 220 then moves the filter plate 210. Personnel can then pull the arc-shaped plate 221 to remove the filter plate 210 and the connecting rod 220, bringing out the packing material on the filter plate 210. This facilitates the removal of the internal packing material and improves practicality.

[0043] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
