Description

Technical Field

[0001] This application relates to the field of chemical experimental equipment technology, and in particular to a fully automated liquid-liquid extraction apparatus. Background Technology

[0002] Liquid-liquid extraction is a commonly used separation technique in chemical experiments. Currently, there are some liquid-liquid extraction devices on the market, but most of them are complex to operate, have low automation, low extraction efficiency, and are prone to causing reagent waste and environmental pollution.

[0003] Conventional liquid-liquid extraction equipment is typically operated manually, requiring researchers to manually add reagents, shake to mix, allow to stand for layering, and separate the liquids—a cumbersome and time-consuming process. While some equipment has achieved partial automation, issues such as low automation levels and inconsistent extraction results still exist.

[0004] Therefore, how to design a fully automated liquid-liquid extraction instrument has become an urgent problem to be solved in this field. Utility Model Content

[0005] In order to provide a fully automated liquid-liquid extraction apparatus, this application provides a fully automated liquid-liquid extraction apparatus.

[0006] The fully automated liquid-liquid extraction apparatus provided in this application adopts the following technical solution:

[0007] A fully automated liquid-liquid extraction instrument includes an instrument panel, a separating funnel, an Erlenmeyer flask, and a residual liquid draining seat. A mounting base is fixedly connected to the top of the instrument panel. A first mounting plate is mounted on one side of the top of the mounting base. The separating funnel is mounted on the first mounting plate. The residual liquid draining seat and the Erlenmeyer flask are sequentially mounted directly below the separating funnel. Multiple sets of the separating funnel, residual liquid draining seat, and Erlenmeyer flask are arranged at intervals. A solenoid valve is installed at the outlet of the separating funnel. A waste liquid collection tank, a pure water tank, and a washing tank are sequentially arranged on the back of the mounting base. The residual liquid draining seat and the waste liquid collection tank are connected... The instrument panel is equipped with a flexible hose and a liquid pump. A two-way pipe is located at the outlet of the liquid pump, connecting to the pure water tank and the washing tank respectively. A connecting pipe is connected to the output end of the liquid pump, and multiple branch pipes are installed on the connecting pipe. A solenoid valve is installed at the connection point of the two-way pipes. The end of each branch pipe away from the connecting pipe extends into the separatory funnel. A second mounting plate for fixing the branch pipe is installed on the mounting base away from the first mounting plate. A fixing device for fixing the residual liquid drain seat is provided on the mounting base. An operation panel is located on the instrument panel.

[0008] By adopting the above technical solution, operators can control the extractor as a whole through the control panel. Multiple component funnels can perform extraction operations simultaneously or different types of extraction, thus accelerating the extraction efficiency throughout the process. After extraction, the residual liquid drain seat can discharge the waste liquid generated during extraction into the waste liquid collection tank through a hose. The conical flask at the bottom can collect the extracted solution. Then, the liquid from the pure water tank and washing tank can be pumped through a two-way pipe and connected to the connecting pipe, and then automatically cleaned in each separating funnel. Operators control the opening and closing of the solenoid valves through the control panel. The entire extraction, collection, and cleaning process is fully automated, improving extraction efficiency.

[0009] Preferably, the instrument panel is equipped with an air pump, the output end of the air pump is equipped with a connecting air pipe, the connecting air pipe is connected to a plurality of air distribution pipes, the end of the air distribution pipe away from the connecting air pipe extends into the interior of the separating funnel, and the input end of the air pump is connected to air.

[0010] By adopting the above technical solution, the operator can control the air pump to inject air into the separatory funnel, thereby further accelerating the extraction efficiency.

[0011] Preferably, the fixing device includes a fixing ring sleeved on the outer circumference of the residual liquid drainage seat and a fixing rod fixedly connected to the fixing ring. One end of the fixing rod away from the fixing ring extends into the mounting base, and the mounting base is provided with a driving component for driving the fixing rod to move.

[0012] By adopting the above technical solution, operators can fix the residual liquid drainage seat by setting a fixing rod and a fixing ring, which enhances the stability of the residual liquid drainage seat and thus enhances the overall stability.

[0013] Preferably, the drive assembly includes a lead screw threaded to the fixed rod, a worm gear sleeved on the outer circumferential surface of the lead screw, and a worm meshing with the worm gear. A rotating rod and a drive motor are rotatably engaged in the mounting base. The axis of the rotating rod and the axis of the worm are on the same straight line and connected together. The output shaft of the drive motor is fixedly connected to the rotating rod. A first sliding groove for sliding engagement of the fixed rod is provided in the mounting base.

[0014] By adopting the above technical solution, the drive motor rotates, which in turn drives the rotating rod to rotate. The rotating rod then drives several worm gears to rotate, which in turn drives the worm wheel to rotate. The worm wheel then drives the lead screw to rotate, and the lead screw then drives the fixed rod to move within the first sliding groove. This allows the operator to move the fixed rod back and forth, thereby enabling the movement of the waste liquid drain seat.

[0015] Preferably, the portion of the branch tube extending into the separatory funnel has multiple small holes.

[0016] By adopting the above technical solution, the small holes on the branch pipe make the clean water entering the separatory funnel spray in all directions, thus improving the cleaning efficiency of the separatory funnel.

[0017] Preferably, the bottom of the conical bottle is provided with a fixed base.

[0018] By adopting the above technical solution, the fixed base plays a role in stabilizing and positioning the conical bottle.

[0019] Preferably, baffles are provided on both sides of the first mounting plate.

[0020] By adopting the above technical solution, the baffle effectively prevents chemical reagents from splashing out during operation and interfering with the outside world.

[0021] Preferably, the liquid pump, the air pump, and the solenoid valve are all wirelessly controlled by an operation panel.

[0022] By adopting the above technical solution, operators can directly control the operation of the instrument throughout the entire process through the control panel, avoiding experimental failures caused by manual operation errors.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Operators can control the extractor via the control panel. Multiple component funnels can perform extraction simultaneously or different types of extraction, thus accelerating extraction efficiency throughout the process. After extraction, the residual liquid drain seat discharges the waste liquid through a hose into the waste liquid collection tank. The conical flask at the bottom collects the extracted solution. Liquid from the pure water tank and washing tank is then pumped through a two-way pipe and connected to the individual separating funnels for automatic cleaning. Operators control the opening and closing of the solenoid valves via the control panel. The entire extraction, collection, and cleaning process is fully automated, improving extraction efficiency.

[0025] 2. The drive motor rotates, causing the rotating rod to rotate. The rotating rod then drives several worm gears to rotate, which in turn drives the worm wheel to rotate. The worm wheel rotates, driving the lead screw to rotate. The lead screw rotates, causing the fixed rod to move within the first sliding groove. This allows the operator to move the fixed rod back and forth, thereby moving the position of the waste liquid drain seat.

[0026] 3. The small holes on the branch pipe allow the clean water entering the separatory funnel to spray in all directions, improving the cleaning efficiency of the separatory funnel. Attached Figure Description

[0036] The operator controls the instrument operation through the control panel 26. The fixed base 53 plays a role in stabilizing and positioning the conical flask 12. The baffle 54 effectively prevents chemical reagents from splashing and interfering with the outside world during the operation of the instrument.

[0037] Reference Figure 1 , Figure 2 The fixing device 3 includes a fixing ring 31 and a fixing rod 32. The fixing ring 31 is sleeved on the outer circumferential surface of the residual liquid drainage seat 13, and the fixing rod 32 is fixedly connected to the fixing ring 31. The end of the fixing rod 32 away from the fixing ring 31 extends into the interior of the mounting base 14. The fixing ring 31 and the fixing rod 32 provide a stable support effect for the residual liquid drainage seat 13.

[0038] Reference Figure 1 , Figure 3 A solenoid valve 16 is installed at the outlet of the separating funnel 11. A waste liquid collection tank 17, a pure water tank 18, and a washing tank 19 are sequentially arranged on the back of the mounting base 14. The waste liquid collection tank 17 and the residual liquid drain seat 13 are connected by a flexible hose 2. A liquid pump 21 is installed at the top of the instrument panel 1. A two-way pipe 22 is connected to the inlet of the liquid pump 21, and the two-way pipe 22 is connected to the pure water tank 18 and the washing tank 19 respectively. A connecting pipe 23 is connected to the output end of the liquid pump 21, and multiple branch pipes 24 are connected to the connecting pipe 23. The end of the branch pipe 24 away from the connecting pipe 23 extends into the interior of the separating funnel 11. A second mounting plate 25 for fixing the branch pipes 24 is installed on the side of the mounting base 14 away from the first mounting plate 15, and the second mounting plate 25 is fixedly connected to the mounting base 14.

[0039] Reference Figure 4 , Figure 5 The instrument panel 1 is equipped with an air pump 27, and the output end of the air pump 27 is connected to an air pipe 28. Multiple gas distribution pipes 29 are connected to the air pipe 28, with the end of each gas distribution pipe 29 extending into the separatory funnel 11 away from the air pipe 28. The operator controls the air pump 27 to inject air into the separatory funnel 11, thereby further accelerating the extraction efficiency.

The mounting base 14 has a first sliding groove 52, the inner wall of which slides in engagement with the outer wall of the fixed rod 32.

[0041] After the extraction is completed, the separatory funnel 11 discharges the waste liquid through the residual liquid drain seat 13 and then through the hose 2 into the waste liquid collection tank 17. After collection, the drive motor 51 rotates, which in turn drives the rotating rod 5 to rotate. The rotating rod 5 rotates, which in turn drives several worm gears 43 to rotate, which in turn drives the worm wheel 42 to rotate. The worm wheel 42 rotates, which drives the lead screw 41 to rotate. The lead screw 41 rotates, which drives the fixed rod 32 to move in the first sliding groove 52, thus facilitating the operator to move the fixed rod 32 back and forth, and thus move the position of the waste liquid drain seat. Then the extracted solution can be discharged into the conical flask 12.

[0042] The implementation principle of the fully automatic liquid-liquid extraction instrument in this application embodiment is as follows: This application accelerates the extraction efficiency by injecting gas into the separating funnel 11 through the air pump 27; during the entire extraction process, there is no operator contact, ensuring the physical and mental health of the operator; after extraction, the waste liquid in the separating funnel 11 is precisely controlled by the solenoid valve 16 and discharged into the waste liquid collection tank 17 through the residual liquid drain seat 13 and the hose 2 for centralized treatment; the pure water tank 18 and the washing tank 19 can clean the inside of the separating funnel 11 under the action of the liquid pump 21, and at the same time, the small hole 241 on the branch pipe 24 further enhances the scattering cleaning of the separating funnel 11, improving the cleaning effect; the operator can set and operate the extraction instrument through the operation panel 26.
