Description

Technical Field

[0001] This utility model relates to the technical field of pharmaceutical manufacturing, and in particular to a device for recovering alcohol precipitate in the manufacturing of traditional Chinese medicine. Background Technology

[0002] In the pharmaceutical process of traditional Chinese medicine (TCM), alcohol precipitation (also known as the water-alcohol method) is a commonly used refining method. Its principle is based on the difference in solubility of active ingredients and impurities in TCM extracts in ethanol of different concentrations. By adding ethanol, some impurities (such as polysaccharides, proteins, and mucilage) in the extract precipitate, forming a sediment at the bottom. After the sediment is discharged from the TCM extract, a recovery device is needed to recover the ethanol contained in the sediment. Currently, the commonly used recovery device is an ethanol distillation recovery tower. This tower utilizes the difference in boiling points between ethanol and water, heating the sediment to evaporate the ethanol, which is then condensed and recovered. However, this method has the following problems: the sediment contains not only ethanol but also some solid impurities from the TCM and some precipitated proteins or polysaccharides. These impurities, once inside the distillation tower, can easily clog the pipes and form scale, requiring frequent cleaning and making it inconvenient to use. Therefore, an ethanol distillation recovery tower with a pre-filtration function is needed.

[0003] In view of the problems existing in the above-mentioned prior art, it is necessary to study and design a device for recovering alcohol precipitate in the preparation of traditional Chinese medicine, so as to overcome the problems existing in the prior art. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a device for recovering alcohol precipitate in traditional Chinese medicine manufacturing by filtering the precipitate before distillation and recovery, thereby reducing solid impurities in the precipitate, reducing the amount of solid impurities entering the ethanol distillation and recovery tower, and reducing the risk of scaling or clogging of pipelines in the ethanol distillation and recovery tower. The device is easy to use and highly practical.

[0005] This utility model discloses an apparatus for recovering alcohol precipitate in traditional Chinese medicine manufacturing. It includes a base plate and an ethanol distillation recovery tower, with the tower fixedly mounted on the upper part of the base plate. The apparatus also includes a filter box, a feed funnel, a filtration mechanism, and a conveying mechanism. The filter box contains a chamber, and a feed funnel connected to this chamber is located at the top of the filter box. A valve is installed on the feed funnel. The filtration mechanism is installed within the chamber of the filter box and performs filtration. The input end of the conveying mechanism is connected to the lower part of the chamber of the filter box, and the output end is connected to the ethanol distillation recovery tower. When recovering alcohol from the precipitate, the precipitate is first added to the chamber of the filter box through the feed funnel. Indoors, the sludge is filtered to remove solid impurities. Then, the conveying mechanism is activated to transport the filtered sludge from the lower part of the filter chamber to the ethanol distillation recovery tower. In the ethanol distillation recovery tower, the sludge is distilled to produce ethanol gas, which is then condensed and recovered in the condenser. This method filters the sludge before distillation, reducing solid impurities and minimizing the risk of scaling or pipe blockage in the ethanol distillation recovery tower. It is convenient and highly practical.

[0006] Furthermore, the filtration mechanism includes a filter plate, a fixed plate, and a moving mechanism. A chute is provided in the middle of the filter chamber, and an opening communicating with the chamber is provided on the right side of the filter chamber. The opening is located on the right side of the fixed plate of the chute. The front and rear parts of the filter plate are slidably installed in the chute of the filter chamber. The filter plate is provided with multiple vertically communicating filter holes. The filter plate is located in the filter chamber. The fixed plate is fixedly installed on the right end of the filter plate, and the left end of the fixed plate contacts the opening at the right end of the filter chamber. The fixed plate is used to seal the opening. The filter plate is installed on the moving mechanism, which is used to move the filter plate left and right. The filter plate is located on the left side of the opening. When the sediment liquid is added to the filter chamber through the feed funnel, the sediment liquid is filtered by the filter plate as it passes through the filter plate. Solid impurities in the sediment liquid remain on the upper part of the filter plate, and the filtered sediment liquid falls to the lower part of the filter chamber. The filtration by the filter plate reduces the solid impurities in the sediment liquid.

[0007] Furthermore, the moving mechanism includes a support plate, hydraulic cylinder A, a support plate, a push rod, and a sliding rod. The support plate is fixedly mounted on the base plate, hydraulic cylinder A is fixedly mounted on the upper end of the support plate, and the support plate is fixedly mounted on the support plate. The push rod and sliding rod are both slidably mounted on the support plate and the left side wall of the filter box. The power output end of hydraulic cylinder A is connected to the left end of the push rod, and the filter plate is fixedly mounted on the right end of the push rod and the sliding rod. When it is necessary to clean the impurities filtered out from the upper end of the filter plate, hydraulic cylinder A is opened, and hydraulic cylinder A moves the filter plate to the right through the push rod, thereby moving the filter plate out through the opening on the right side of the filter box chamber. Then, the operator cleans the solid impurities on the upper end of the filter plate from the right side of the filter box. After cleaning, the filter plate is moved to the left into the filter box chamber, thus improving convenience.

[0008] Furthermore, it also includes a lifting plate, multiple push rods, a lifting mechanism, and a positioning mechanism. Multiple push rods are installed at the lower end of the lifting plate, which is mounted on the lifting mechanism for raising and lowering the plate. The positioning mechanism is mounted on the base plate and located on the right side of the fixed plate, serving a positioning function. The diameter of the push rods is smaller than the diameter of the filter holes on the filter plate. When cleaning solid impurities on the filter plate, the filter plate is moved out through the opening at the right end of the filter box. Simultaneously, the filter plate drives the fixed plate to move to the right until the fixed plate contacts the positioning mechanism. At this point, the filter plate stops moving to the right. The multiple filter holes on the filter plate are then located below the multiple push rods. The lifting mechanism then lowers the lifting plate, causing the multiple push rods to descend and insert into the multiple filter holes on the filter plate, pushing out impurities stuck in the filter holes. This facilitates cleaning of impurities in the filter holes and improves convenience.

[0009] Furthermore, the lifting mechanism includes a fixed frame, a hydraulic cylinder B, a drive rod, and a guide rod. The fixed frame is fixedly mounted on the base plate, the hydraulic cylinder B is fixedly mounted on the upper end of the fixed frame, and the drive rod and guide rod are both slidably mounted on the fixed frame. The upper end of the drive rod is connected to the power output end of the hydraulic cylinder B, and the lifting plate is fixedly mounted on the lower ends of the drive rod and guide rod. When adjusting the height of the lifting plate, the hydraulic cylinder B is opened, which causes the drive rod to adjust its height, thereby causing the lifting plate to drive multiple push rods to adjust its height. This facilitates the adjustment of the push rod height.

[0010] Furthermore, the positioning mechanism includes a mounting plate and a contact sensor. The mounting plate is fixedly mounted on the base plate, and a contact sensor is provided at the left end of the mounting plate. The contact sensor is located on the right side of the fixed plate. When cleaning impurities in multiple filter holes on the filter plate, the filter plate moves to the right, which in turn moves the fixed plate to the right until the fixed plate contacts the contact sensor. The contact sensor transmits a contact signal to an external controller, which then stops the hydraulic cylinder A from driving the push rod to move to the right, thereby stopping the filter plate from moving. At this time, the multiple filter holes on the filter plate are located below the multiple push rods, which facilitates the positioning of the filter plate.

[0011] Furthermore, the conveying mechanism includes a conveying pump, an inlet pipe, and a outlet pipe. The input end of the conveying pump is connected to the lower part of the filter chamber through the inlet pipe, and the output end of the conveying pump is connected to the ethanol distillation recovery tower through the outlet pipe. By turning on the conveying pump, the filtered sediment liquid in the lower part of the filter chamber can be sequentially distilled and recovered in the ethanol distillation recovery tower through the inlet pipe, the conveying pump, and the outlet pipe. This facilitates the conveying of the liquid.

[0012] Furthermore, it also includes a filter screen and a sealing door. The filter screen is fixedly installed inside the filter box chamber and is located below the filter plate. The filter box is provided with a cleaning port that communicates with the chamber. The sealing door is installed outside the cleaning port, which is located in front of the filter screen. After the sediment liquid is filtered by the filter plate, the sediment liquid falls onto the filter screen and is filtered again by the filter screen, which improves the filtration effect.

[0013] Compared with the prior art, the present invention has the following advantages: This utility model provides a device for recovering alcohol precipitate in traditional Chinese medicine manufacturing. Before distilling and recovering the precipitate, the device can filter the precipitate to reduce solid impurities in the precipitate, thereby reducing the amount of solid impurities entering the ethanol distillation and recovery tower and reducing the risk of scaling or clogging of pipelines in the ethanol distillation and recovery tower. It is convenient to use and highly practical. Attached Figure Description

[0024] Example 1 like Figures 1 to 5 The present invention relates to an apparatus for recovering alcohol precipitate in traditional Chinese medicine manufacturing, comprising a base plate 1, an ethanol distillation recovery tower 2, a filter box 3, a feed funnel 4, a filtration mechanism, and a conveying mechanism. The ethanol distillation recovery tower 2 is fixedly installed on the upper part of the base plate 1. The filter box 3 has a chamber, and the upper part of the filter box 3 is provided with a feed funnel 4 communicating with the chamber. A valve is provided on the feed funnel 4. The filtration mechanism is installed in the chamber of the filter box 3 and has a filtration function. The input end of the conveying mechanism is connected to the lower part of the chamber of the filter box 3, and the output end of the conveying mechanism is connected to the ethanol distillation recovery tower 2. When recovering alcohol from the precipitate, the precipitate is first added to the filter box through the feed funnel 4. In chamber 3, the solid impurities in the sludge are filtered out by a filtration mechanism. Then, the conveying mechanism is opened to transport the filtered sludge from the lower part of chamber 3 to ethanol distillation recovery tower 2. In ethanol distillation recovery tower 2, the sludge is distilled to produce ethanol gas, which is then condensed and recovered in the condenser of ethanol distillation recovery tower 2. This method can filter the sludge before distillation recovery, reducing the amount of solid impurities in the sludge and the amount of solid impurities entering ethanol distillation recovery tower 2. This reduces the risk of scaling or clogging of pipelines in ethanol distillation recovery tower 2, making it convenient to use and highly practical.

[0025] like Figure 2 and Figure 3 The filtration mechanism includes a filter plate 5, a fixed plate 6, and a moving mechanism. A chute is provided in the middle of the filter box 3 chamber, and an opening communicating with the chamber is provided on the right side of the filter box 3 chamber. The opening is located on the right side of the fixed plate 6 of the chute. The front and rear parts of the filter plate 5 are slidably installed in the chute of the filter box 3 chamber. The filter plate 5 is provided with multiple vertically connected filter holes. The filter plate 5 is located in the chamber of the filter box 3. The fixed plate 6 is fixedly installed on the right end of the filter plate 5, and the left end of the fixed plate 6 contacts the opening at the right end of the filter box 3 chamber. The fixed plate 6 is used to seal the opening. The filter plate 5 is installed on the moving mechanism, which is used to move the filter plate 5 left and right. The filter plate 5 is located on the left side of the opening. When the sediment liquid is added to the chamber of the filter box 3 through the feed funnel 4, the sediment liquid is filtered by the filter plate 5 as it passes through the filter plate 5. Solid impurities in the sediment liquid remain on the upper end of the filter plate 5. The filtered sediment liquid falls to the lower part of the filter box 3 chamber. The solid impurities in the sediment liquid are reduced by the filtration of the filter plate 5.

[0026] like Figure 3The moving mechanism includes a support plate 7, a hydraulic cylinder A8, a support plate 9, a push rod 10, and a sliding rod 11. The support plate 7 is fixedly installed on the base plate 1, the hydraulic cylinder A8 is fixedly installed on the upper end of the support plate 9, and the support plate 9 is fixedly installed on the support plate 7. The push rod 10 and the sliding rod 11 are both slidably installed on the left side wall of the support plate 7 and the filter box 3. The power output end of the hydraulic cylinder A8 is connected to the left end of the push rod 10, and the filter plate 5 is fixedly installed on the right end of the push rod 10 and the sliding rod 11. When it is necessary to clean the impurities filtered out from the upper end of the filter plate 5, the hydraulic cylinder A8 is opened. The hydraulic cylinder A8 moves the filter plate 5 to the right through the push rod 10, thereby moving the filter plate 5 out through the opening on the right side of the filter box 3. Then, the operator cleans the solid impurities on the upper end of the filter plate 5 from the right side of the filter box 3. After cleaning, the filter plate 5 is moved to the left into the filter box 3. This improves convenience.

[0027] like Figure 1 and Figure 2 It also includes a lifting plate 12, multiple push rods 13, a lifting mechanism, and a positioning mechanism. The multiple push rods 13 are all installed at the lower end of the lifting plate 12. The lifting plate 12 is installed on the lifting mechanism, which is used to lift the lifting plate 12. The positioning mechanism is installed on the base plate 1 and is located on the right side of the fixed plate 6. The positioning mechanism has a positioning function. The diameter of the push rods 13 is smaller than the diameter of the filter holes on the filter plate 5. When cleaning solid impurities on the filter plate 5, the filter plate 5 is moved out through the opening at the right end of the filter box 3. At the same time, the filter plate 5 drives the fixed plate 6 to move to the right until the fixed plate 6 moves to the right and contacts the positioning mechanism. At this time, the filter plate 5 stops moving to the right. At this time, the multiple filter holes on the filter plate 5 are respectively located below the multiple push rods 13. Then, the lifting mechanism lowers the lifting plate 12, and the lifting plate 12 drives the multiple push rods 13 to lower, so that the multiple push rods 13 are respectively inserted into the multiple filter holes on the filter plate 5, pushing out the impurities stuck in the multiple filter holes, which facilitates the cleaning of impurities in the filter holes and improves convenience.

[0028] like Figure 1 and Figure 2 The lifting mechanism includes a fixed frame 14, a hydraulic cylinder B15, a drive rod 16, and a guide rod 17. The fixed frame 14 is fixedly mounted on the base plate 1. The hydraulic cylinder B15 is fixedly mounted on the upper end of the fixed frame 14. The drive rod 16 and the guide rod 17 are both slidably mounted on the fixed frame 14. The upper end of the drive rod 16 is connected to the power output end of the hydraulic cylinder B15. The lifting plate 12 is fixedly mounted on the lower end of the drive rod 16 and the guide rod 17. When adjusting the height of the lifting plate 12, the hydraulic cylinder B15 is opened. The hydraulic cylinder B15 causes the drive rod 16 to adjust its height, which in turn causes the lifting plate 12 to drive multiple push rods 13 to adjust their height. This facilitates the adjustment of the height of the push rods 13.

[0029] like Figure 2 and Figure 5 The positioning mechanism includes a mounting plate 18 and a contact sensor 19. The mounting plate 18 is fixedly mounted on the base plate 1, and the contact sensor 19 is located on the left end of the mounting plate 18. The contact sensor 19 is located on the right side of the fixed plate 6. When cleaning the impurities in the multiple filter holes on the filter plate 5, the filter plate 5 moves to the right, and the filter plate 5 drives the fixed plate 6 to move to the right until the fixed plate 6 contacts the contact sensor 19. The contact sensor 19 transmits the contact signal to the external controller, and the controller stops the hydraulic cylinder A8 from driving the push rod 10 to move to the right, thereby stopping the filter plate 5 from moving. At this time, the multiple filter holes on the filter plate 5 are located below the multiple push rods 13, which facilitates the positioning of the filter plate 5.

[0030] like Figure 4 The conveying mechanism includes a conveying pump 20, an inlet pipe 21, and a drain pipe 22. The input end of the conveying pump 20 is connected to the lower part of the filter chamber 3 through the inlet pipe 21, and the output end of the conveying pump 20 is connected to the ethanol distillation recovery tower 2 through the drain pipe 22. When the conveying pump 20 is turned on, the filtered sludge liquid in the lower part of the filter chamber 3 enters the ethanol distillation recovery tower 2 for distillation and recovery in sequence through the inlet pipe 21, the conveying pump 20, and the drain pipe 22, which facilitates the conveying of liquid.

[0031] Example 2 Based on Example 1, such as Figure 1 and Figure 2 It also includes a filter screen 23 and a sealing door 24. The filter screen 23 is fixedly installed in the chamber of the filter box 3 and is located below the filter plate 5. The filter box 3 is provided with a cleaning port that communicates with the chamber. The sealing door 24 is installed on the outside of the cleaning port, which is located in front of the filter screen 23. After the sediment liquid is filtered by the filter plate 5, the sediment liquid falls onto the filter screen 23 and is filtered again by the filter screen 23, which improves the filtration effect.

[0032] It should be added that: all electrical equipment in this case is connected to an external controller, which coordinates and controls the operation of each piece of electrical equipment.

[0033] The ethanol distillation recovery tower 2, filter plate 5, hydraulic cylinder A8, contact sensor 19, delivery pump 20 and filter screen 23 of this utility model for recovering alcohol precipitate in traditional Chinese medicine manufacturing are all commercially available. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
