Description

Technical Field

[0001] The utility model relates to the field of chemical engineering, in particular to a funnel which can be used for extraction. Background Art

[0002] In chemical laboratories and industrial production, extraction is a commonly used separation and extraction technology. Based on the different solubility of different substances in different solvents, by contacting the mixture with an appropriate solvent, the target substance will dissolve in the solvent, while other components may remain insoluble or have a low solubility. Through repeated extraction and separation processes, the target substance can be gradually extracted. The extraction funnel, as one of the important tools in extraction technology, originated in early chemical laboratories.

[0003] Existing funnels that can be used for extraction are similar to separatory funnels, which are usually made of glass or acid-resistant plastics, have a long neck and a conical bottom. The design of this funnel allows the liquid to be layered in the funnel, making it easy to separate liquids of different densities. The separatory funnel is usually equipped with a valve or piston to control the discharge and separation of the fluid.

[0004] However, the existing funnels that can be used for extraction often have no scale and only have a piston. During the titration process, accurately controlling the amount of solution added is crucial to the accuracy of the experimental results. The funnel without a scale makes it difficult to determine the amount of solution added, which may lead to uncertainty or error in the titration results. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a funnel that can be used for extraction, aiming to improve the problem that the existing funnel that can be used for extraction has no scale and only has one piston, which may cause uncertainty or error in the titration result.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a funnel that can be used for extraction, comprising a column tube, a spherical tank fixedly connected to the top of the column tube, an injection tube fixedly connected to the top of the spherical tank, a stopper slidably connected to the inside of the injection tube, a piston 1 rotatably connected to the inside of the column tube, a handle 1 fixedly connected to one side of the outer wall of the piston 1, a piston 2 rotatably connected to the inside of the column tube, a handle 2 fixedly connected to one side of the outer wall of the piston 2, scale lines are provided on the outer wall of the column tube, and a rotating component is provided on the outer wall of the column tube.

[0007] Furthermore, the rotating assembly comprises a fixed block and a rotating shell, the interior of the rotating shell is rotatably connected to the outer wall of the fixed block, and one side of the outer wall of the fixed block is fixedly connected to the outer wall of the column tube.

[0008] Furthermore, a spring is fixedly connected inside the fixed block, one end of the spring is fixedly connected to a sliding block 2, and a sealing ring is provided between the piston 2 and the column tube.

[0009] Furthermore, a rotating column 1 is fixedly connected inside the rotating shell.

[0010] Furthermore, a round block is rotatably connected inside the rotating shell, one side of the outer wall of the round block is fixedly connected to one side of the outer wall of the fixed block, and the inside of the round block is slidably connected to the second outer wall of the piston.

[0011] Furthermore, the outer wall of the rotating column 1 is rotatably connected to a transmission rod, and the bottom of the transmission rod is rotatably connected to the rotating column 2.

[0012] Furthermore, a slider 1 is fixedly connected to one side of the outer wall of the second rotating column, a slide groove 1 is provided inside the round block, and the outer wall of the slider 1 is slidably connected to the inside of the slide groove 1.

[0013] Furthermore, a limiting block is fixedly connected to one side of the outer wall of the sliding block 1, a sliding groove 2 is provided inside the piston 2, and the outer wall of the limiting block is slidably connected to the inside of the sliding groove 2.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, the effect of accurately controlling the amount of solution added is achieved through the coordination between the column tube, piston 1, piston 2, handle 1, handle 2 and scale lines, thereby solving the problem that the existing funnel that can be used for extraction has no scale and only has one piston, which may lead to uncertainty or error in the experimental results, and reducing the error of the experimental results.

[0016] 2. In the utility model, the piston can be replaced by cooperating with the rotating shell, the first rotating column, the transmission rod, the second rotating column, the slider and the limit block, thereby solving the problem that when the piston in the funnel is damaged, the entire funnel needs to be replaced because the piston cannot be replaced, thereby reducing the use cost.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a funnel that can be used for extraction, including a column tube 1, a spherical tank 2 is fixedly connected to the top of the column tube 1, a liquid injection tube 3 is fixedly connected to the top of the spherical tank 2, a plug 4 is slidably connected inside the liquid injection tube 3, a piston 1 5 is rotatably connected inside the column tube 1, a handle 1 7 is fixedly connected to one side of the outer wall of the piston 1 5, a piston 2 6 is rotatably connected inside the column tube 1, a handle 2 8 is fixedly connected to one side of the outer wall of the piston 2 6, a scale line 9 is provided on the outer wall of the column tube 1, and a rotating component is provided on the outer wall of the column tube 1;

[0024] Specifically, when using the funnel that can be used for extraction, first remove the stopper 4, then pour the extraction liquid into the spherical jar 2 through the injection tube 3, then cover the stopper 4, and then rotate the handle 1 7 to make the solution flow into the column tube 1. When there is a large amount of solution in the column tube 1, rotate the handle 1 7 to close the piston 1 5, and then turn the handle 2 8 according to the required amount of solution. The handle 2 8 drives the piston 2 6 to open it, and the solution in the column tube 1 begins to flow downward. While the solution flows downward, the eyes look directly at the scale line 9 where the solution is located. When the required amount of solution is reached, turn the handle 2 8 to close its piston 2 6. The funnel can accurately control the amount of solution to reduce errors.

[0025] Reference Figure 1 - Figure 3 The rotating assembly includes a fixed block 10 and a rotating shell 11, the rotating shell 11 is rotatably connected to the outer wall of the fixed block 10, and one side of the outer wall of the fixed block 10 is fixedly connected to the outer wall of the column tube 1;

[0026] Specifically, when the piston of the extraction funnel needs to be replaced, the piston 2 6 can be replaced by rotating the rotating shell 11 to release the limit of the rotating shell 11 on the piston 2, which is convenient and quick.

[0027] Reference Figure 1 - Figure 3 A spring 19 is fixedly connected inside the fixed block 10, and a slider 20 is fixedly connected to one end of the spring 19. A sealing ring 21 is arranged between the piston 26 and the column tube 1. A rotating column 12 is fixedly connected inside the rotating shell 11. A round block 22 is rotatably connected inside the rotating shell 11. One side of the outer wall of the round block 22 is fixedly connected to one side of the outer wall of the fixed block 10. The inner part of the round block 22 is slidably connected to the outer wall of the piston 26. The outer wall of the rotating column 12 is rotatably connected to the transmission rod 13. The bottom of the transmission rod 13 is rotatably connected to the rotating column 24. One side of the outer wall of the rotating column 14 is fixedly connected to the slider 16. A slide groove 15 is provided inside the round block 22. The outer wall of the slider 16 is slidably connected inside the slide groove 15. One side of the outer wall of the slider 16 is fixedly connected to the limiting block 17. A slide groove 28 is provided inside the piston 26. The outer wall of the limiting block 17 is slidably connected inside the slide groove 28.

[0028] Specifically, when it is necessary to replace the piston of the funnel that can be used for extraction, first pull the slider 20 to release the limit of the slider on the rotating shell 11, and then rotate the rotating shell 11, the rotating shell 11 drives the transmission rod 13 to move, and then the slider 16 is forced to move upward, and then the slider 16 drives the limit block 17 to move upward to release the limit on the piston 2 6. At this time, the piston 2 6 can be removed and replaced. The tail end of the piston 1 5 is provided with the same limit mechanism, so the piston 1 5 and the piston 2 6 can be replaced to prevent the entire funnel from being replaced due to the non-replaceable piston 1 5 or piston 2 6. A sealing ring 21 is provided between the piston 2 6 and the column tube 1, and a sealing ring 21 is also provided between the piston 1 5 and the column tube 1, so when the piston 1 5 and the piston 2 6 are in use, there will be no solution leakage.

[0029] Working principle: when using the funnel that can be used for extraction, first add the extraction liquid into the spherical tank 2 through the injection tube 3, then cover the stopper 4, and then open the piston 5 to allow part of the extraction liquid to flow into the column tube 1, and then close the piston 5. At this time, look directly at the scale line 9 to note the position of the extraction liquid, and then slowly open the piston 2 6 according to the required amount of the extraction liquid. When the required amount is reached, close the piston 2 6. When the funnel that can be used for extraction is used for a long time and it is necessary to replace the piston 1 5 and the piston 2 6, first move the slider 2 20, and then rotate the rotating shell 11 respectively. The rotation of the rotating shell 11 will drive the rotating column 12 to move, and then the slider 16 is driven to rise through the transmission rod 13. At this time, the slider 16 drives the limit block 17 to rise, and the piston 2 6 can be removed for replacement.
