Abstract
Description
Technical Field
[0001] This utility model relates to the field of traditional Chinese medicine processing technology, specifically to a residue extrusion structure for a traditional Chinese medicine purification device. Background Technology
[0002] Traditional Chinese medicine purification refers to the process of separating the active ingredients from complex mixtures and removing impurities through a series of technological methods in order to improve the quality and efficacy of traditional Chinese medicine preparations.
[0003] In existing traditional Chinese medicine (TCM) purification processes, the medicinal plants are placed in a filter cartridge, which is then placed in a reaction vessel. Solvents are added to initiate the reaction and purify the herbs. However, after purification, residue remains in the filter cartridge, and this residue absorbs the purified herbal solution. Therefore, the residue needs to be squeezed after purification. However, most existing squeezing devices simply apply pressure, which is not conducive to rotating the residue and applying pressure, resulting in poor solvent extraction. Therefore, we propose a residue squeezing structure for TCM purification equipment. Utility Model Content
[0004] The purpose of this invention is to provide a residue extrusion structure for a traditional Chinese medicine purification device, which solves the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a residue extrusion structure for a traditional Chinese medicine purification device, comprising a filter cylinder, and further comprising:
[0006] A sleeve, wherein a pressure plate is provided at the tail end of the sleeve, and an installation groove is provided on all four sides of the bottom of the pressure plate. A pressure roller is rotatably installed in the inner cavity of the installation groove, and a fixing plate is fixed on the outer wall of the sleeve.
[0007] A rotating shaft movably passes through the sleeve and is fixedly connected to the top of the pressure plate. A rotating assembly is connected to the top of the rotating shaft, and the rotating assembly is used to drive the rotating shaft to rotate.
[0008] A connecting plate is disposed on the upper side of the servo motor. The connecting plate is connected to a fixed plate through a lifting assembly, and the lifting assembly is used to drive the fixed plate to rise and fall.
[0009] By adopting the above technical solution, the filter cartridge is first installed in the reaction vessel. After the Chinese medicine is placed in the filter cartridge for purification, the remaining residue in the filter cartridge is then lowered by the lifting component, which in turn lowers the sleeve and the pressure plate, thereby applying pressure to the residue in the filter cartridge. The rotating component is then activated to drive the rotating shaft to rotate, which in turn drives the pressure plate to rotate. This allows the pressure roller to be used to roll the residue, thereby improving the extrusion effect of the residual medicine in the residue.
[0010] In a preferred embodiment of this utility model, the lifting assembly includes:
[0011] An electric actuator, which is fixedly installed at the top center of the connecting plate;
[0012] A lifting plate, which is fixedly installed on the outer end of the push rod of the electric actuator;
[0013] The limiting rods are two in number, and the two limiting rods movably pass through the connecting plate and are fixedly connected to the top of the fixing plate;
[0014] The electric actuator drives the lifting plate to rise and fall, which in turn drives the limit rod to rise and fall, thereby driving the fixed plate to rise and fall, and indirectly driving the sleeve and pressure plate to rise and fall.
[0015] In a preferred embodiment of this utility model, the rotating assembly includes:
[0016] A servo motor, wherein the outer end of the drive shaft of the servo motor is fixedly connected to the top of the rotating shaft;
[0017] A retainer is fixedly fitted onto the outer wall of the servo motor, and the tail end of the retainer is fixedly connected to the top of the fixing plate;
[0018] The servo motor drives the shaft to rotate, thereby rotating the pressure plate, and the cage ensures the stability of the servo motor.
[0019] In a preferred embodiment of this utility model, scrapers are fixed on all four sides of the bottom of the pressure plate. The lowest point of the scraper is flush with the lowest point of the pressure roller, and the two side walls of the scraper are provided with inclined surfaces. During the rotation and pressure application process, the scraper will adhere to the inner wall of the filter cylinder and insert into the inner cavity of the medicine residue. Thus, the scraper can rotate to scrape the medicine residue that the pressure roller cannot reach and that is adhered to the inner wall of the filter cylinder. The scraped medicine residue will move along the inclined surface of the scraper, thereby moving the medicine residue towards the inner side of the filter cylinder. This allows the pressure roller to roll and press the scraped medicine residue when it rolls again, which is beneficial to further improve the extrusion effect of the solvent in the press.
[0020] In a preferred embodiment of this utility model, the outer diameter of the pressure plate is the same as the inner diameter of the filter cylinder, so that the pressure plate can fit against the inner wall of the filter cylinder when it descends inside the filter cylinder, thereby scraping off the dregs adhering to the inner wall.
[0021] In a preferred embodiment of this utility model, connection holes are provided on both sides of the top of the connecting plate;
[0022] The connection holes facilitate the installation and fixation of the device.
[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0024] The residue extrusion structure of the traditional Chinese medicine purification equipment in this application applies pressure to the residue in the filter cylinder through the pressure plate. The servo motor drives the rotating shaft to rotate, which in turn drives the pressure plate to rotate. The pressure roller at the bottom of the pressure plate can roll on the pressed residue, thereby achieving rotational pressure and improving the solvent extrusion effect in the residue.
[0025] During the rotation and pressure application process, the scraper adheres to the inner wall of the filter cylinder and inserts into the inner cavity of the residue. The scraper can then rotate to scrape the residue that the pressure roller cannot reach, which is attached to the inner wall of the filter cylinder. The scraped residue moves along the inclined surface of the scraper, allowing it to move towards the inner side of the filter cylinder. This allows the pressure roller to roll over the scraped residue when it rolls again, thereby further improving the extrusion effect of the solvent in the press. Attached Figure Description

[0034] Please see Figure 1-3 This utility model provides a technical solution: a residue extrusion structure for a traditional Chinese medicine purification device, including a filter cylinder 3, and further comprising:
[0035] The sleeve 11 has a pressure plate 12 at its tail end. The pressure plate 12 has mounting grooves 17 on all four sides of its bottom. A pressure roller 18 is rotatably mounted inside the mounting groove 17. A fixing plate 1 is fixed to the outer wall of the sleeve 11.
[0036] A rotating shaft 21 is movably inserted through the sleeve 11 and fixedly connected to the top of the pressure plate 12. A rotating assembly is connected to the top of the rotating shaft 21, which is used to drive the rotating shaft 21 to rotate.
[0037] A connecting plate 16 is disposed on the upper side of the servo motor 2. The connecting plate 16 is connected to the fixed plate 1 through a lifting assembly. The lifting assembly is used to drive the fixed plate 1 to lift.
[0038] It should be understood that in actual use, the filter cartridge 3 is first installed in the reaction vessel. After the Chinese medicine is placed in the filter cartridge 3 for purification, there is residual dregs in the filter cartridge 3. At this time, the lifting component drives the fixed plate 1 to descend, thereby the sleeve 11 and the pressure plate 12 descend accordingly, thereby applying pressure to the dregs in the filter cartridge 3. The rotating component can drive the rotating shaft 21 to rotate, thereby driving the pressure plate 12 to rotate, and then the pressure roller 18 can be used to roll the dregs, which is beneficial to improving the extrusion effect of the residual medicine in the dregs.
[0039] Furthermore, connection holes are provided on both sides of the top of the connecting plate 16, which facilitates the installation and fixing of the device.
[0040] Furthermore, the outer diameter of the pressure plate 12 is the same as the inner diameter of the filter cylinder 3, so that when the pressure plate 12 descends inside the filter cylinder 3, it can fit against the inner wall of the filter cylinder 3, thereby scraping off the residue adhering to the inner wall.
[0041] like Figure 1 As shown, the lifting assembly includes:
[0042] Electric actuator 15 is fixedly installed at the top center of the connecting plate 16;
[0043] Lifting plate 14 is fixedly installed on the outer end of the push rod of electric push rod 15;
[0044] There are two limiting rods 13, which movably pass through the connecting plate 16 and are fixedly connected to the top of the fixing plate 1.
[0045] It should be understood that by driving the lifting plate 14 to rise and fall through the electric actuator 15, the limiting rod 13 can be driven to rise and fall, thereby driving the fixed plate 1 to rise and fall, and indirectly driving the sleeve 11 and the pressure plate 12 to rise and fall.
[0046] like Figure 1 As shown, the rotating assembly includes:
[0047] Servo motor 2, the outer end of the drive shaft of servo motor 2 is fixedly connected to the top of the rotating shaft 21;
[0048] The cage is fixedly fitted onto the outer wall of the servo motor 2, and the tail end of the cage is fixedly connected to the top of the fixing plate 1.
[0049] It should be understood that the servo motor 2 can drive the rotating shaft 21 to rotate, thereby driving the pressure plate 12 to rotate, and the cage can ensure the stability of the servo motor 2.
[0050] like Figure 2 and 3 As shown, scrapers 19 are fixed on all four sides of the bottom of the pressure plate 12. The lowest point of the scraper 19 is flush with the lowest point of the pressure roller 18. The two side walls of the scraper 19 are provided with inclined surfaces.
[0051] It should be understood that during the rotation and pressure application process, the scraper 19 will adhere to the inner wall of the filter cylinder 3 and insert into the inner cavity of the residue. Thus, the scraper 19 can rotate to scrape the residue that the pressure roller 18 cannot reach and that is adhered to the inner wall of the filter cylinder 3. The scraped residue will move along the inclined surface of the scraper 19, thereby allowing the residue to move towards the inner side of the filter cylinder 3. This allows the pressure roller 18 to roll and press the scraped residue again, which is beneficial to further improve the extrusion effect of the solvent in the press.
