Technical Field
[0001] This utility model relates to the technical field of chemical reagent and auxiliary agent extraction equipment, and more specifically, to an extraction reaction device for chemical reagents and auxiliaries. Background Technology
[0002] Currently, in the preparation of chemical reagents and auxiliaries in the laboratory, extraction and reaction operations are required to obtain the desired auxiliaries. Extraction utilizes the difference in solubility of substances in immiscible solvents to transfer substances from one solvent to another. Commonly used extractants include carbon tetrachloride and benzene. Extraction generally uses a separatory funnel to separate the solution, and the separated solution reacts with other substances to obtain the desired type of auxiliary.
[0003] In the actual extraction process, the separatory funnel must first be leak-tested. After the leak test, the liquid to be extracted is poured into the separatory funnel, with the total volume generally not exceeding three-quarters of the funnel's capacity. The separatory funnel is then shaken. After shaking, the separatory funnel is placed on an iron stand to allow the layers to separate. The glass stopper is opened to ensure that the atmospheric pressure inside and outside the funnel is the same. The stopcock at the bottom of the separatory funnel is opened to allow the lower layer of liquid to flow into the beaker from the bottom. After the liquid has flowed out, the stopcock is closed, the cap is opened, and the remaining upper layer of liquid inside the funnel is poured from the top of the funnel into another beaker, completing the extraction operation. Subsequent reaction experiments can then be carried out.
[0004] For the above operations, the leak detection and shaking operations are all done manually, which is time-consuming. In addition, the separatory funnel needs to be rotated repeatedly during the process. Improper human operation can cause the separatory funnel to fall and be damaged. Moreover, the manual shaking effect is not good enough, and the extractant and solution inside the separatory funnel are not mixed evenly, which will prolong the subsequent solution settling time and result in low extraction efficiency. Utility Model Content
[0005] The purpose of this invention is to provide an extraction reaction device for chemical reagents and auxiliaries. This extraction reaction device is designed with a special leak detection and shaking support to assist experimental personnel in performing extraction reaction operations with a separatory funnel. It replaces the traditional manual rotation for leak detection and shaking operations, improves the shaking effect and consistency, and thus reduces the subsequent solution settling time and improves extraction efficiency.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] An extraction reaction apparatus for chemical reagent auxiliaries includes a separatory funnel for auxiliary extraction, with a glass stopper embedded in the upper opening of the separatory funnel. The extraction reaction apparatus includes symmetrical support legs on both sides, which are connected to the lower end of a vertical base plate. A vibrating spring rod is connected inward to the front side of the base plate via L-shaped connecting rods arranged in an equilateral triangle. The inner ends of the vibrating spring rods are all connected to a vibrating disk. A through groove is formed at the center of the vibrating disk, and a rotating bearing is embedded inside the through groove. A rotating shaft is connected to the inner rotating part of the rotating bearing. A turntable is connected to the front of the rotating shaft, and the rear of the rotating shaft is connected to the output shaft of a drive motor via a coupling. The drive motor is supported and fixed by a connecting plate on the rear side of the vibrating disk. A vibration motor is also connected and fixed to one side of the rear side of the vibrating disk. A support plate is fixed to the upper part of the outer side of the turntable, and a V-shaped support plate is fixed to the lower end of the outer side of the turntable. A recessed support seat is provided in the middle of the outer side of the turntable.
[0008] As a further optimization of this solution, the support plate has threaded holes machined on its surface, and an adjusting bolt is screwed into the threaded holes. A top plate is connected below the adjusting bolt. A separating funnel is clamped between the top plate and the V-shaped support plate. The lower surface of the top plate presses downward against the upper surface of the glass stopper of the separating funnel, and the V-shaped support plate presses upward against the inclined outlet port of the separating funnel. The shape of the recessed area of the support seat is adapted to the shape of the outer side of the largest radius area of the separating funnel.
[0009] As a further optimization of this solution, a push plate is fixed at the lower edge of the turntable, and a micro-motion limit switch is fixed on one side of the upper edge of the outer surface of the oscillating disk. After the turntable rotates, it drives the push plate to push the lever of the micro-motion limit switch.
[0010] As a further optimization of this solution, a threaded sleeve is fixed at the center of the upper surface of the top plate, and an adjusting bolt is screwed into the threaded sleeve.
[0011] As a further optimization of this solution, the drive motor, vibration motor, and micro limit switch are all connected to an external power supply and control panel via circuitry.
[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows:
[0013] This invention, through the design of a turntable combined with a top plate, V-shaped support plate, and support base, can simulate the turning action of a separatory funnel during manual leak detection and shaking operation. The separatory funnel is rotated at a certain angle in the vertical plane, and this angle is limited by a micro-motion limit switch. At the same time, a vibration motor is used to shake the shaking plate, replacing the traditional manual shaking operation, improving the shaking effect and consistency, thereby reducing the subsequent solution settling time and improving extraction efficiency.

Detailed Implementation
[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0021] To address the issues that existing separatory funnel extraction processes involve manual operation for leak detection and shaking, which is time-consuming, and the repeated rotation of the separatory funnel during the process can lead to damage if not handled properly, as well as insufficient manual shaking, resulting in uneven mixing of the extractant and solution inside the separatory funnel, which prolongs the subsequent solution settling and separation time and leads to low extraction efficiency.
[0022] like Figure 1 and Figure 2As shown, this application includes a separatory funnel 9 for extracting auxiliary agents. A glass stopper 19 is embedded in the upper opening of the separatory funnel 9. The extraction reaction device includes two symmetrical support legs 1. The upper part of the support legs 1 is connected to the lower end of the vertical base plate 2. The front side of the base plate 2 is connected to an oscillating spring rod 4 through an L-shaped connecting rod 3 distributed in an equilateral triangle. The inner ends of the oscillating spring rod 4 are all connected to the oscillating disk 5. A through groove is opened at the center of the oscillating disk 5, and a rotating bearing 10 is embedded in the through groove. A rotating shaft is connected to the rotating part inside the rotating bearing 10. A turntable 6 is connected to the front of the rotating shaft, and the rear of the rotating shaft is connected to the output shaft of the drive motor 11 through a coupling. The drive motor 11 is supported and fixed by a connecting plate 12 on the rear side of the oscillating disk 5. A vibration motor 13 is also connected and fixed to one side of the rear side of the oscillating disk 5. A support plate 7 is fixed at the upper end of the outer side of the turntable 6, and a V-shaped support plate 8 is fixed at the lower end of the outer side of the turntable 6. A support seat 16 with a recess is provided at the middle position of the outer side of the turntable 6.
[0023] like Figure 3 As shown, the support plate 7 has a threaded hole on its surface and an adjusting bolt 17 is screwed into the threaded hole. A top plate 18 is connected below the adjusting bolt 17. A separating funnel 9 is clamped between the top plate 18 and the V-shaped support plate 8. The lower surface of the top plate 18 presses down against the upper surface of the glass stopper 19 of the separating funnel 9, and the V-shaped support plate 8 presses up against the inclined outlet port of the separating funnel 9.
[0024] like Figure 4 As shown, the shape of the recessed area of the support 16 is adapted to the shape of the outer side of the largest radius area of the separatory funnel 9. A push plate 15 is fixed at the lower edge of the turntable 6. A micro switch 14 is fixed on the upper side of the outer surface of the oscillating plate 5. After the turntable 6 rotates, it drives the push plate 15 to push the lever of the micro switch 14. A threaded sleeve is fixed at the center of the upper surface of the top plate 18. An adjusting bolt 17 is screwed into the inside of the threaded sleeve.
[0025] Specifically, when using this device, the drive motor 11, the vibration motor 13, and the micro limit switch 14 are all connected to an external power supply and control panel via a circuit. The control panel is equipped with start / stop and adjustment knobs.
[0026] During the leak detection operation of the separatory funnel 9, the experimenter closes the piston of the separatory funnel 9 and adds clean water into the separatory funnel 9. Then, the glass bottle stopper 19 is placed on the funnel, and the separatory funnel 9 is aligned and placed into the recessed area of the support 16. At the same time, the slanted liquid outlet at the lower end of the separatory funnel 9 enters between the V-shaped support plates 8 for support. Then, the top plate 18 is rotated and pressed down by adjusting the bolt 17, so that the lower surface of the top plate 18 presses down against the upper surface of the glass bottle stopper 19 of the separatory funnel 9. The top plate 18 is detachably connected to the adjusting bolt 17. The top plate 18 with a lower surface shape can be replaced according to the top surface shape of different separatory funnel 9 glass bottle stoppers 19.
[0027] Next, the drive motor 11 is started via the control panel, causing the turntable 6 to rotate. Once the turntable 6 rotates, it drives the push plate 15 to push the lever of the micro-switch 14, stopping the drive motor 11. The separating funnel 9 then reaches the desired liquid level. Figure 5 At the tilted position shown, let it stand for one minute and observe whether there is any leakage at the glass stopper 19. The tilt angle of the micro-switch 14 can be 10 to 15 degrees. Then, continue to start the drive motor 11 to reverse and reset to the initial position of the separatory funnel 9. Loosen the adjusting bolt 17, rotate the glass stopper 19 180 degrees, and repeat the above operation. If there is no leakage in both cases, the separatory funnel 9 is airtight. Pour out the clear water.
[0028] When shaking the separatory funnel 9, pour the liquid to be extracted into the separatory funnel 9, generally not exceeding three-quarters of its volume. Then shake the separatory funnel 9, repeating the above steps until the separatory funnel 9 is rotated to the desired position. Figure 5 At the tilted position shown, the vibration motor 13 is started to drive the oscillating plate 5 to oscillate periodically. During the oscillation pause, the piston of the separating funnel 9 is opened to release the air. Generally, the air is released two to three times to balance the pressure inside and outside the separating funnel 9. Finally, the solution is allowed to stand and separate. The vibration motor 13 replaces the traditional manual oscillation operation. The machine oscillation effect and consistency are better, thereby reducing the subsequent solution standing and separating time and improving the extraction efficiency.
