Description

Technical Field

[0001] This utility model relates to an extraction device, specifically a chemical pharmaceutical synthesis extraction device, belonging to the technical field of chemical pharmaceutical synthesis equipment. Background Technology

[0002] In the process of chemical synthesis, extraction is a key separation and purification process. Its purpose is to efficiently separate the target chemical substance from the mixed system in order to improve the purity and yield of the final product. The quality of extraction directly affects the quality of chemical products, production efficiency and production cost, and the amount of extractant added is one of the core parameters that determines the extraction effect.

[0003] Chinese Patent No. CN215916516U discloses an extraction device for traditional Chinese medicine raw materials used in basic medicine. The device includes an extraction tank with a feed pipe fixedly connected to its top surface. A heating box is fixedly connected to the top surface of the extraction tank, and a rotating shaft is movably sleeved on the top surface of the heating box. The lower end of the rotating shaft passes through the extraction tank and extends into its interior. A stirring rod located inside the extraction tank is fixedly connected to the outer surface of the rotating shaft. The rotating shaft drives the stirring rod to rotate while simultaneously blowing hot air into the solution. This combined action of stirring and hot air accelerates the dissolution of the medicinal components, significantly improving the actual dissolution rate. To improve extraction efficiency and thus enhance the purification effect of the extract, existing devices often rely on manual addition or simple mechanical conveying, lacking a precise quantitative control mechanism. Manual addition is heavily influenced by subjective factors such as operator experience and skill level, making it impossible to accurately control the amount of extract added, which can easily lead to over- or under-addition. Over-addition results in wasted extractant, increased production costs, and may also burden subsequent separation processes. Under-addition leads to incomplete extraction of the target substance, reducing product yield and purity. Furthermore, traditional devices struggle to dynamically adjust the amount of extract added based on real-time operating conditions during the extraction process. Summary of the Invention

[0004] This invention provides a chemical pharmaceutical synthesis extraction device to solve the problem of difficulty in adjusting the amount of extractant added.

[0005] The present invention achieves the above objectives through the following technical solution: a chemical drug synthesis extraction device, comprising an extraction tank, wherein a quantitative mechanism is provided above the extraction tank; The metering mechanism includes fixed columns symmetrically fixed to the top of the extraction tank, a storage tank fixed between the two sets of fixed columns, a metering tube slidably connected to the bottom of the storage tank, and the bottom of the metering tube passing through the addition port on the surface of the extraction tank and extending into the interior of the extraction tank. Sliding seats are symmetrically fixed to both sides of the metering tube, and the sliding seats slide inside the fixed columns. A locking mechanism capable of locking the sliding seats is provided inside the fixed columns. A valve body is installed at the bottom of the surface of the metering tube. A hollow tube is fixed inside the storage tank. A partition plate with an annular through hole on the surface is fixed at the bottom of the hollow tube. An air bladder capable of sealing the through hole is installed inside the partition plate, and the air bladder is connected to the hollow tube.

[0006] As a further improvement of this utility model: an air pump is installed at the top of the liquid storage tank, and the output end of the air pump is connected to the hollow tube.

[0008] As a further improvement of this utility model: an observation window is provided on the surface of the liquid storage tank, and a transparent partition is embedded inside the observation window.

[0009] As a further improvement of this utility model, an annular seal is embedded at the bottom of the liquid storage tank near the metering tube.

[0010] As a further embodiment of this utility model: the locking mechanism includes a first locking tooth symmetrically fixed inside the fixed column near the sliding seat, a slider symmetrically slidably connected inside the first locking tooth, and a second locking tooth matching the first locking tooth fixed on the surface of the slider, an elliptical block is provided between the two sets of sliders, and the elliptical block rotates inside the sliding seat, and magnetic blocks that can attract each other are symmetrically fixed between the two sets of sliders.

[0013] The beneficial effects of this utility model are: 1. This device, through the cooperation of the metering tube and the locking mechanism, can flexibly adjust the depth of the metering tube into the storage tank according to different extraction process requirements. Through the synergistic action of the elliptical block, slider, magnetic block and toothed structure in the locking mechanism, the position of the metering tube can be stably locked to avoid displacement after adjustment. At the same time, the transparent scale plate in the fixed column can intuitively display the position of the sliding seat, indirectly and accurately control the volume of the metering tube, and ensure the amount of extractant added.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 like Figures 1 to 8 As shown, a chemical drug synthesis extraction device includes an extraction tank 1, and a metering mechanism 2 is provided above the extraction tank 1; The metering mechanism 2 includes fixed columns 25 symmetrically fixed to the top of the extraction tank 1. A storage tank 21 is fixed between the two sets of fixed columns 25. A metering tube 22 is slidably connected to the bottom of the storage tank 21, and the bottom end of the metering tube 22 passes through the addition port on the surface of the extraction tank 1 and extends into the interior of the extraction tank 1. Sliding seats 212 are symmetrically fixed to both sides of the metering tube 22, and the sliding seats 212 slide inside the fixed columns 25. A locking mechanism 3 capable of locking the sliding seats 212 is provided inside the fixed columns 25. A valve body 23 is installed at the bottom of the surface of the metering tube 22. A hollow tube 29 is fixed inside the storage tank 21. The bottom end of the hollow tube 29... A partition plate 210 with an annular through hole on its surface is fixedly installed. An air bladder 211 capable of sealing the through hole is installed inside the partition plate 210, and the air bladder 211 is connected to the hollow tube 29. The storage tank 21 can store the extract to be used, providing raw material guarantee for subsequent extraction operations. The metering tube 22 can be adjusted by sliding to adjust the insertion depth, which can adapt to the amount of extract to be added required by different extraction processes. The air bladder 211 and the hollow tube 29 work together to flexibly control whether the extract flows into the metering tube 22, avoiding liquid leakage in non-metering stages. The valve body 23 can accurately control the delivery of the extract to the extraction tank 1 after metering, and finally realize the metered addition of the extract, solving the problem of inaccurate addition in traditional devices.

[0019] Furthermore, an air pump 28 is installed at the top of the storage tank 21, and the output end of the air pump 28 is connected to the hollow tube 29. The air pump 28 serves as a power source. By inflating the hollow tube 29, the air bag 211 can be expanded, thereby blocking the annular through hole of the partition plate 210, blocking the flow of extractant between the storage tank 21 and the metering tube 22, and ensuring the stability of the liquid volume in the metering tube 22. By evacuating the air, the air bag 211 can be contracted, opening the annular through hole, and allowing the extractant to flow smoothly into the metering tube 22.

[0020] The fixed column 25 has a through groove for the sliding seat 212 to slide, and a transparent scale plate 26 is embedded in the through groove. The transparent scale plate 26 allows the staff to directly observe the position of the sliding seat 212, thereby indirectly determining the depth of the quantitative tube 22 into the storage tank 21, and accurately matching the required amount of extractant to be added.

[0021] The storage tank 21 has an observation window 27 on its surface, and a transparent partition is embedded inside the observation window 27. With the observation window 27 and the transparent partition, the staff can check the remaining amount of extract in the storage tank 21 at any time, promptly detect any shortage of extract and replenish it, and avoid interruption of the extraction operation due to raw material shortage.

[0022] An annular seal is embedded at the bottom of the storage tank 21 near the metering tube 22. The annular seal can fit tightly against the outer wall of the metering tube 22, filling the gap between the metering tube 22 and the storage tank 21, effectively preventing the extract from leaking out of the gap during storage or metering.

[0023] Example 2 Improvements based on Example 1: The locking mechanism 3 includes a first locking tooth 34 symmetrically fixed inside the fixed post 25 near the sliding seat 212. A slider 35 is symmetrically slidably connected inside the first locking tooth 34, and a second locking tooth 37 matching the first locking tooth 34 is fixed on the surface of the slider 35. An elliptical block 33 is provided between the two sets of sliders 35, and the elliptical block 33 rotates inside the sliding seat 212. Magnetic blocks 36 that can attract each other are symmetrically fixed between the two sets of sliders 35. When the short axis of the elliptical block 33 faces the slider 35, the magnetic block 36 drives the slider 35 to move closer through magnetic force, causing the second locking tooth 37 to disengage from the first locking tooth 34, releasing the lock on the sliding seat 212 and facilitating the adjustment of the position of the quantitative tube 22. When the long axis of the elliptical block 33 faces the slider 35, it squeezes the slider 35 to overcome the magnetic force and separates it, causing the second locking tooth 37 to engage with the first locking tooth 34, locking the position of the sliding seat 212, ensuring the depth of the quantitative tube 22 is fixed, realizing the flexible switching between locking and unlocking of the locking mechanism 3, and ensuring the stability of quantitative adjustment.

[0024] Furthermore, a worm gear 31 is rotatably connected inside the sliding seat 212, and a worm wheel 32 is meshed with the surface of the worm gear 31. One end of the worm wheel 32 is connected to the elliptical block 33. The meshing transmission structure of the worm gear 31 and the worm wheel 32 can convert the operator's operation of rotating the worm gear 31 into the rotational motion of the elliptical block 33. The direction and angle of the elliptical block 33 can be precisely controlled through simple manual operation, thereby conveniently adjusting the locking or unlocking state of the locking mechanism 3.

[0025] The extraction tank 1 is rotatably connected to a stirring rod 7. A motor 6 for driving the stirring rod 7 to rotate is fixed on the upper side of the extraction tank 1. A funnel-shaped sieve plate 9 is fixed at the bottom of the extraction tank 1, and a slag discharge pipe 8 is connected to the bottom of the sieve plate 9. The bottom of the slag discharge pipe 8 penetrates the interior of the extraction tank 1 and extends to the outside of the extraction tank 1. A liquid outlet pipe 5 is fixedly connected to one side of the bottom of the extraction tank 1. The motor 6 drives the stirring rod 7 to rotate at high speed, which can fully stir the raw material and extract in the extraction tank 1, accelerate the transfer of the target substance from the raw material phase to the extract liquid phase, and greatly improve the extraction efficiency. The sieve plate 9 can intercept and filter the solid residue after extraction, allowing the extract containing the target substance to flow smoothly through the filter holes into the bottom of the tank, and then be discharged and collected from the liquid outlet pipe 5. The slag discharge pipe 8 can discharge the intercepted solid residue, realizing efficient solid-liquid separation after extraction.

[0026] It should be noted that the bottom surface of the extraction tank 1 is set as an inclined surface towards the outlet pipe 5, which facilitates the centralized discharge of the extract liquid inside the extraction tank 1 through the outlet pipe 5.

[0027] Working principle: When using this device, the operator injects the extractant to be used into the tank 21 through the opening. Simultaneously, the remaining extractant level is visually confirmed through the observation window 27 on the surface of the tank 21 to avoid affecting subsequent operations due to insufficient extractant. Based on the required amount of extractant for this extraction process, the insertion depth of the metering tube 22 into the tank 21 is adjusted. First, the worm 31 inside the sliding seat 212 is rotated. The worm 31 meshes with the worm wheel 32, driving the elliptical block 33 connected to one end of the worm wheel 32 to rotate. At this time, the short axis of the elliptical block 33 faces the two sets of sliders 35. The magnetic blocks 36 between the sliders 35 attract each other due to magnetic force, causing the sliders 35 to move closer together. This disengages the second locking tooth 37 on the surface of the slider 35 from the first locking tooth 34 inside the fixed column 25, releasing the locking mechanism 3 from fixing the sliding seat 212. The sliding seat 212 is then manually pushed up and down along the through groove inside the fixed column 25. The metering tube 22 moves synchronously. During the process, the position of the sliding seat 212 is observed through the transparent scale plate 26 in the groove of the fixed column 25, which indirectly determines the depth of the metering tube 22 into the storage tank 21. After adjustment, the worm gear 31 is rotated in the opposite direction so that the major axis of the elliptical block 33 faces the two sets of sliders 35. The elliptical block 33 squeezes the slider 35 to overcome the magnetic force of the magnetic block 36 and separates it to both sides until the second tooth 37 on the surface of the slider 35 is fully engaged with the first tooth 34. The sliding seat 212 is locked and the position of the metering tube 22 is fixed. At the same time, the air pump 28 at the top of the storage tank 21 is started. The air pump 28 inflates the air bag 211 inside the partition plate 210 through the hollow tube 29. The air bag 211 gradually expands and blocks the flow of extractant between the storage tank 21 and the metering tube 22. Then, the valve body 23 at the bottom of the surface of the metering tube 22 is opened, and the extractant in the metering tube 22 flows into the extraction tank 1 below along the pipe, completing the precise metering of extractant. The chemical mixture to be extracted is added into the extraction tank 1 through the feed inlet 4. After the feed inlet 4 is closed, the motor 6 on the upper side of the extraction tank 1 is started. The motor 6 drives the internal stirring rod 7 to rotate at high speed, which mixes and stirs the raw materials and extract liquid in the tank, accelerating the transfer of the target substance from the raw material phase to the extract liquid phase and improving the extraction efficiency. After the extraction reaction is completed, the motor 6 is turned off. The solid residue is intercepted and filtered through the sieve plate 9 with a funnel structure fixed at the bottom of the extraction tank 1. The extract liquid containing the target substance flows into the bottom of the extraction tank 1 through the filter holes of the sieve plate 9 under the action of gravity and is discharged from the outlet pipe 5. The valve on the slag discharge pipe 8 connected to the bottom of the sieve plate 9 is opened, and the intercepted solid residue is discharged from the extraction tank 1 along the slag discharge pipe 8, completing the solid-liquid separation.
