Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid receiving technology, and in particular to a liquid receiving device for a chromatography column. Background Technology
[0002] A chromatography column is an experimental device used to separate and purify compounds, widely applied in chemistry, drug development, and biotechnology. Its basic principle is to separate different substances based on the difference in distribution between the stationary and mobile phases. In use, the chromatography column is mounted on a stand with the outlet at the bottom suspended in the air. The operator places a receiving cup below the outlet to collect the liquid released from the column. Because the outlet is lower than the receiving cup, the cup needs to be tilted at an angle when placed or removed, limiting the amount of liquid inside. If the outlet is higher than the cup, while this makes placement and removal easier, liquid may splash during collection. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention provides a liquid receiving device for chromatography columns, which can prevent liquid splashing and facilitate the placement or removal of the receiving cup.
[0004] In order to achieve the purpose of this utility model, the following solution is proposed:
[0005] A chromatography column liquid receiving device includes a clamp, a lifting assembly, a base, and a guardrail.
[0006] The clamp is located on one side of the support plate;
[0007] The lifting assembly is located at the bottom of the support plate, and the movable end of the lifting assembly passes through the support plate and is connected to the lifting plate.
[0008] The base includes a circular plate and an arc-shaped baffle on top of it. The circular plate is located on top of the support plate. A through groove for accommodating the lifting plate is provided at the center of the circular plate. A liquid receiving cup is placed on the circular plate and is used to receive the liquid released from the chromatography column.
[0009] The guardrail includes an arc-shaped vertical plate and multiple arc-shaped horizontal plates on one side. The inner wall of the arc-shaped baffle is provided with multiple arc-shaped grooves. The arc-shaped horizontal plates are slidably disposed in the corresponding arc-shaped grooves. The circular plate is provided with an arc-shaped guide groove. The bottom of the arc-shaped vertical plate is slidably disposed along the guide groove. When the guardrail is pulled out from the arc-shaped groove, it is used to limit the connection of the liquid cup.
[0010] Furthermore, the outer wall of the curved vertical plate is equipped with a handle.
[0011] Furthermore, the inner diameters of the curved vertical plate, the curved horizontal plate, and the curved baffle are the same.
[0012] Furthermore, the fixture includes a side plate and a bottom plate, a clamping plate, and a top plate located on one side of the side plate. The clamping plate is slidably mounted up and down along the side plate, and a screw is threadedly connected to the top plate. The bottom of the screw is rotatably connected to the clamping plate, and rotating the screw is used to adjust the distance between the clamping plate and the bottom plate.
[0013] Furthermore, the sides of the plywood and the base plate opposite each other are provided with a rubber layer.
[0014] Furthermore, the top surfaces of both the circular plate and the lifting plate are flush.
[0015] The advantages of this invention are as follows: the clamps allow the entire device to be installed on the edge of the experimental table, thus avoiding excessive use of the table's area and space; the base and guardrail have an ingenious structure, allowing the guardrail to be stored inside the base when not in use, and pulling the guardrail out of the base to limit the liquid receiving cup inside the base, preventing it from tipping over; the lifting assembly allows for automatic adjustment of the liquid receiving cup's height, preventing liquid splashing during the receiving process.

[0020] like Figure 1 As shown, this embodiment provides a chromatography column liquid receiving device, including a support plate 16, a clamp 1, a lifting assembly 2, a base 3, and a guardrail 4.
[0021] Specifically, clamp 1 is located on one side of support plate 16. The function of clamp 1 is to clamp and fix the entire liquid receiving device to the edge of the experimental table. The specific implementation of clamp 1 is as follows: Figure 3As shown, the clamp 1 includes a side plate 14 and a bottom plate 11, a clamping plate 12, and a top plate 13 disposed on one side of the side plate 14. The side plate 14 is fixedly connected to a support plate 16. The top plate 13 and the bottom plate 11 are both fixedly disposed. The clamping plate 12 is slidably disposed along the side plate 14. A screw 15 is threadedly connected to the top plate 13. A knob is provided on the top of the screw 15. The bottom of the screw 15 is rotatably connected to the clamping plate 12. When the screw 15 is rotated, the distance between the clamping plate 12 and the bottom plate 11 can be reduced, thereby clamping and fixing the entire liquid receiving device to the edge of the experimental table. The opposite sides of the clamping plate 12 and the bottom plate 11 are provided with a rubber layer to increase friction and prevent damage to the surface of other objects.
[0022] Specifically, the lifting component 2 is located at the bottom of the support plate 16. The movable end of the lifting component 2 passes through the support plate 16 and is connected to the lifting plate 21. The power source of the lifting component 2 can be a cylinder or a hydraulic cylinder, which is used to adjust the height of the lifting plate 21.
[0023] Specifically, such as Figure 1 As shown, the base 3 includes a circular plate 31 and an arc-shaped baffle 32 on the top of the circular plate 31. The circular plate 31 and the arc-shaped baffle 32 are coaxially arranged, and the central angle occupied by the arc-shaped baffle 32 is less than 180°. The purpose of this design is to facilitate the direct placement of the liquid receiving cup in the base 3 or the direct removal of the liquid receiving cup from the base 3. The circular plate 31 is located on the top of the support plate 16. The center of the circular plate 31 is provided with a through groove 311 that runs vertically through it. The lifting plate 21 is matched in the through groove 311, and the top surfaces of the circular plate 31 and the lifting plate 21 are flush.
[0024] Specifically, such as Figure 1 , Figure 2 As shown, the guardrail 4 includes an arc-shaped vertical plate 41 and multiple arc-shaped horizontal plates 42 arranged in a vertical array. The multiple arc-shaped horizontal plates 42 are all located on one side of the arc-shaped vertical plate 41. The inner wall of the arc-shaped baffle 32 has multiple arc-shaped grooves 33. The end of the arc-shaped groove 33 facing the arc-shaped vertical plate 41 communicates with the outside. The arc-shaped horizontal plates 42 slide within their corresponding arc-shaped grooves 33. The inner diameters of the arc-shaped vertical plate 41, the arc-shaped horizontal plates 42, and the arc-shaped baffle 32 are the same. The circular plate 31 has an arc-shaped guide groove 312, which is coaxially arranged with the circular plate 31. The bottom of the arc-shaped vertical plate 41 slides along the guide groove 312. Figure 1 As shown, the guardrail 4 is in a retracted state at this time, and the arc-shaped horizontal plates 42 are all retracted into the arc-shaped groove 33. In order to facilitate the operation of the guardrail 4, this embodiment has a handle 43 on the outer wall of the arc-shaped vertical plate 41.
[0025] Instructions for use: Use clamp 1 to hold and fix the entire liquid receiving device to the edge of the experimental table, ensuring that the base 3 is located below the outlet of the chromatography column; place the liquid receiving cup on the circular plate 31; pull the guardrail 4 out from the arc-shaped groove 33 to limit the liquid receiving cup and prevent it from tipping over during lifting and lowering. The guardrail 4 should be in the following position. Figure 4 As shown; after placing the receiving cup, the lifting plate 21 is moved up using the lifting component 2. The lifting plate 21 will lift the receiving cup until the outlet of the chromatography column is located inside the receiving cup and close to the inner bottom of the receiving cup; the chromatography column releases the liquid into the receiving cup, and the lifting plate 21 moves down at a certain rate or at a certain interval.
[0026] One point to note here: Figure 4 In this state, the arc-shaped vertical plate 41 rotates from the first end of the guide groove 312 to the second end of the guide groove 312, and the arc-shaped horizontal plate 42 does not detach from the arc-shaped baffle 32. The guardrail 4 continues to maintain this state and will not move arbitrarily. On the one hand, it can rely on the friction between the arc-shaped vertical plate 41 and the guide groove 312. On the other hand, a magnet can be provided at a specific position at the second end of the guide groove 312 to attract the arc-shaped vertical plate 41.
[0027] The above embodiments are only used to illustrate the technical concept and features of this utility model, and are not intended to be unique or to limit this utility model. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
