Description

Technical Field

[0001] This invention relates to the field of pharmaceutical production technology, and more specifically to a pharmaceutical production equipment. Background Technology

[0002] The medicinal liquid can be concentrated in several ways. The first method is high-temperature concentration, which is the traditional method. It involves heating the liquid to over 100 degrees Celsius, resulting in high energy consumption, low heat utilization, and a harsh production environment. Furthermore, high temperatures may affect the effective components of the traditional Chinese medicine. The second method is negative pressure concentration. Under negative pressure, the boiling temperature of the medicinal liquid is lowered (below 100 degrees Celsius), which will not damage the components of the medicinal liquid.

[0003] In existing technologies, Chinese medicinal materials are usually boiled in an extraction tank for extraction and then transferred to a concentration device for concentration. However, in actual applications, some medicinal material residues are mixed with the liquid. Therefore, before the transfer, the mixture of liquid and medicinal material residues needs to be poured out of the extraction tank and filtered. This process is quite cumbersome, and the temperature of the liquid will also be lost during the pouring and filtering process, which will affect the concentration process. Summary of the Invention

[0004] The purpose of this invention is to provide a pharmaceutical production device that solves the following technical problems:

[0005] Some medicinal herb residues are mixed with the medicinal liquid. Therefore, before transfer, the mixture of medicinal liquid and medicinal herb residues needs to be poured out of the extraction tank and filtered. The process is quite cumbersome, and the temperature of the medicinal liquid will also be lost during the pouring and filtering process, which will affect the concentration process.

[0012] Preferably, the bearing plate is slidably sleeved on the first support shaft, the first screw is rotatably arranged on the first support shaft, and the other end of the first screw is fixed to the second support shaft;

[0013] The second support shaft is equipped with a sealing disc for sealing the opening of the extraction tank.

[0014] Preferably, a number of positioning holes are circumferentially opened at the mouth of the extraction tank, and a number of positioning seats are fixedly arranged on the outer edge of the sealing plate, with positioning rods for insertion into the positioning holes fixedly arranged at the bottom of the positioning seats.

[0015] Preferably, the bottom of the first support shaft is provided with several sets of support rods corresponding to each column of filter holes in a circumferential manner, and several sets of insertion rods corresponding to the filter holes are provided on the support rods.

[0016] The first support shaft is equipped with a telescopic spring, and several sets of top rods are fixedly arranged circumferentially on the base plate, with the top rods and support rods in a misaligned state.

[0017] Preferably, a sealing rod is also fixedly arranged at the bottom of each of the support rods;

[0018] The bottom plate is provided with a drain hole that communicates with the conical cavity.

[0019] Preferably, a filter disc is also spirally sleeved on the first screw, the filter disc slides against the inner wall of the extraction tank, a circular groove is opened on the filter disc, four sets of partitions are fixedly arranged in a circumferential array in the circular groove, a fan-shaped filter groove is formed between two sets of adjacent partitions, and a filter screen is embedded in the fan-shaped filter groove.

[0020] Among them, when the two sets of symmetrical partitions are arranged in an array on both sides, several sets of adsorption holes are opened. A cavity communicating with the adsorption holes is opened in the partition. Two sets of adsorption tubes communicating with the cavity in the partition are symmetrically slidably arranged on the sealing plate. The two sets of adsorption tubes are connected to the negative pressure tube through the adsorption plate. The end of the negative pressure tube is connected to the adsorption pump.

[0021] Preferably, the end of the second support shaft away from the first screw is fixed to the gear, and a rack for meshing with the gear is slidably arranged on the housing, and the rack is fixed to the synchronous belt mechanism that drives it to move horizontally.

[0022] Preferably, the drive unit includes a bracket fixedly mounted on the housing, a second screw rotatably mounted in the bracket, the second screw being fixed to the output end of a drive motor fixedly mounted on the bracket, and a nut spirally mounted on the second screw, the nut being fixed to a drive seat rotatably mounted on a second support shaft via a drive rod.

[0023] The beneficial effects of this invention are:

[0024] (1) Before extracting the medicinal liquid, the present invention first drives the carrier plate to rise to a preset height through the drive unit, and then places the Chinese medicinal materials on the carrier plate. The annular scraper can limit the position of the Chinese medicinal materials to prevent them from falling off the carrier plate. Then, the drive unit drives the carrier plate back to the bottom of the extraction tank. Next, clean water is added to the extraction tank and heated by the first heating element. After boiling for a period of time, the boiling is stopped. Finally, the boiled medicinal liquid is discharged to the concentration tank through the bottom of the extraction tank. During this process, based on the setting of the filter holes, only the medicinal liquid can pass through the filter holes, and the Chinese medicinal residue cannot pass through the filter holes, thereby achieving the effect of filtering the medicinal residue and effectively preventing the medicinal residue from entering the concentration tank. After the medicinal liquid is transferred, the carrier plate is driven to rise through the drive unit. During this process, the annular scraper can scrape the medicinal residue attached to the inner wall of the extraction tank onto the carrier plate and discharge it together. There is no need for manual cleaning again. The operation is very convenient and improves the efficiency of drug production.

[0025] (2) In this invention, when the support plate is not at the bottom of the extraction tank, each rod is inserted into the filter hole based on the action of the telescopic spring to seal the filter hole. When the support plate moves toward the bottom of the extraction tank, each push rod first abuts against the bottom of the support plate. As it continues to move downward, the push rod lifts the support plate to a certain height so that the rod is separated from the filter hole. At this time, the telescopic spring is in a stretched state so that the clean water and the extracted medicine can pass through the filter hole. When the medicine is extracted, as the support plate rises, the telescopic spring drives the support plate to reset, and the rod is re-inserted into the filter hole, which can push out the medicine residue that is blocked in the filter hole and avoid clogging the filter hole.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1

[0040] Please see Figure 1 , Figure 5 as well as Figure 7As shown, the present invention is a pharmaceutical production device, including a housing 1. The housing 1 has a first receiving cavity 102 for embedding an extraction tank 4 and a second receiving cavity 101 for embedding a concentration tank 8. In one embodiment of this invention, a first heating element 7 is provided at the bottom of the extraction tank 4 for heating the extraction tank 4, and a second heating element 805 is provided at the bottom of the concentration tank 8 for heating the concentration tank 8. The first heating element 7 and the second heating element 805 are both graphene heating elements or mica heating elements.

[0041] Please see Figure 3 and Figure 4 The extraction tank 4 includes a bottom plate 6. One end of the bottom plate 6 away from the extraction tank 4 is connected to a conical cylinder 410. The conical cylinder 410 and the bottom plate 6 enclose a conical cavity 701. A discharge pipe 411 communicating with the conical cavity 701 is provided at the bottom of the conical cylinder 410. In this embodiment, the first heating element 7 is fixedly arranged in the conical cavity 701 and is attached to the bottom plate 6.

[0042] The extraction tank 4 is equipped with a support plate 5 for carrying Chinese medicinal materials. The support plate 5 has several rows of filter holes 502 arranged in a circumferential array. The outer edge of the support plate 5 is integrally provided with an annular scraper 501 for sliding and adhering to the inner wall of the extraction tank 4. The support plate 5 is connected to a drive unit that drives it to move up and down in the vertical direction.

[0043] It can be explained that before extracting the medicinal liquid, the drive unit first raises the support plate 5 to a preset height, and then the Chinese medicinal materials are placed on the support plate 5. The annular scraper 501 can limit the position of the Chinese medicinal materials to prevent them from falling off the support plate 5. Then, the drive unit drives the support plate 5 back to the bottom of the extraction tank 4. Next, clean water is added to the extraction tank 4 and heated by the first heating element 7. After simmering for a period of time, the process is stopped. Finally, the simmered medicinal liquid is discharged into the concentration tank 8 through the bottom of the extraction tank 4. During this process, based on the setting of the filter hole 502, only the medicinal liquid can pass through the filter hole 502, while the Chinese medicinal residue cannot pass through the filter hole 502, thereby achieving the effect of filtering the medicinal residue and effectively preventing the medicinal residue from entering the concentration tank 8. After the medicinal liquid is transferred, the drive unit raises the support plate 5. During this process, the annular scraper 501 can scrape the medicinal residue attached to the inner wall of the extraction tank 4 onto the support plate 5 and discharge it together. No manual cleaning is required, making the operation very convenient and improving the efficiency of medicine production.

[0044] Example 2

[0045] Based on Example 1, please refer to Figures 3-6The support plate 5 is slidably sleeved on the first support shaft 603. The first screw 609 is rotatably arranged on the first support shaft 603. The other end of the first screw 609 is fixed to the second support shaft 608. The second support shaft 608 is rotatably arranged with a sealing plate 402 for sealing the mouth of the extraction tank 4. Specifically, when the support plate 5 is moved to the bottom of the extraction tank 4, the sealing plate 402 just seals the mouth of the extraction tank 4 to achieve the effect of heat preservation.

[0046] In addition, several sets of positioning holes 401 are circumferentially opened at the mouth of the extraction tank 4, and several sets of positioning seats 403 are fixedly arranged on the outer edge of the sealing disc 402. Positioning rods 404 for insertion into the positioning holes 401 are fixedly arranged at the bottom of the positioning seats 403. Specifically, when the sealing disc 402 seals the mouth of the tank, the positioning rods 404 on its periphery are inserted into the positioning holes 401 to improve the stability of the sealing.

[0047] As a further solution in this embodiment, please refer to Figure 4 and Figure 5 The bottom of the first support shaft 603 is circumferentially arranged with several sets of support rods 605 corresponding to each row of filter holes 502. Each support rod 605 is equipped with several sets of insertion rods 606 corresponding to the filter holes 502. A telescopic spring 604 is provided on the first support shaft 603. Several sets of top rods 601 are circumferentially fixed on the base plate 6, with the top rods 601 and support rods 605 in a misaligned state. Specifically, one end of the telescopic spring 604 is fixed to the bearing plate 5, and the other end is fixed to the end of the first support shaft 603. It should be noted that when the bearing plate 5 is not at the bottom of the extraction tank 4, based on the action of the telescopic spring 604, each insertion rod 606 is inserted into the filter hole 502. To seal the filter holes 502, when the support plate 5 moves toward the bottom of the extraction tank 4, each push rod 601 first abuts against the bottom of the support plate 5. As it continues to move downward, the push rod 601 lifts the support plate 5 to a certain height so that the insertion rod 606 separates from the filter holes 502. At this time, the telescopic spring 604 is in a stretched state so that the clean water and the extracted medicine can pass through the filter holes 502. When the medicine is extracted, as the support plate 5 rises, the telescopic spring 604 drives the support plate 5 to reset, and the insertion rod 606 is re-inserted into the filter holes 502, which can push out the medicine residue blocking the filter holes 502 and avoid clogging the filter holes 502.

[0048] Furthermore, each support rod 605 is also fixedly provided with a sealing rod 607 at its bottom. The bottom plate 6 is provided with a drain hole 602 that communicates with the conical cavity 701. Specifically, when the carrying plate 5 moves towards the bottom of the tank, the sealing rod 607 and the drain hole 602 are inserted to achieve a seal, preventing water and medicine from draining into the conical cavity 701 through the drain hole 602. After the medicine is boiled, the drive unit moves the carrying plate 5 upward a certain distance, causing the sealing rod 607 to separate from the drain hole 602, and the medicine can then drain into the conical cavity 701 through the drain hole 602. It should be noted that when the sealing rod 607 is separated from the drain hole 602, the insert rods 606 still cannot be inserted into the filter hole 502 to prevent the medicine from being unable to drain to the bottom of the tank through the filter hole 502.

[0049] In this embodiment, please refer to Figures 3-4 A filter disc 405 is spirally sleeved on the first screw 609. The filter disc 405 slides against the inner wall of the extraction tank 4. A circular groove 407 is formed on the filter disc 405. Four sets of partitions 406 are fixedly arranged in a circumferential array in the circular groove 407. A fan-shaped filter groove 408 is formed between two adjacent sets of partitions 406. A filter screen is embedded in the fan-shaped filter groove 408. When the two sets of symmetrical partitions 406 are arranged in an array on both sides, several sets of adsorption holes 409 are formed. A cavity communicating with the adsorption holes 409 is formed in the partition 406. Two sets of symmetrical sliding partitions 402 are arranged in a symmetrical array and communicate with the cavities in the partitions 406. The adsorption tube 303 is connected to the negative pressure tube 301 via the adsorption plate 302. The end of the negative pressure tube 301 is connected to the adsorption pump 3. It can be explained that during the decoction process of Chinese medicinal materials, foam will be generated and float on the liquid surface. In this embodiment, by adjusting the height of the filter plate 405 so that the filter plate 405 is just below the liquid surface, the adsorption pump 3 is started. The adsorption pump 3 generates negative pressure in the cavity through the negative pressure tube 301, the adsorption plate 302 and the adsorption tube 303, and sucks out the foam through the adsorption hole 409, thereby achieving the effect of defoaming and improving the quality of the prepared medicine.

[0050] In addition, please see Figure 1 The end of the second shaft 608 away from the first screw 609 is fixed to the gear 206. A rack 104 for meshing with the gear 206 is slidably arranged on the housing 1. The rack 104 is fixed to the synchronous belt mechanism 103 that drives it to move horizontally. Specifically, the synchronous belt mechanism 103 drives the rack 104 to move horizontally in a straight line. The rack 104 can drive the second shaft 608 and the first screw 609 to rotate by meshing with the gear 206. It should be noted that when the drive unit drives the sealing disc 402 to rise, the synchronous belt mechanism 103 can drive the rack 104 to transfer to one side of the sealing disc 402 to avoid interference when the sealing disc 402 rises.

[0051] The synchronous belt mechanism 103 includes two sets of rotating rollers, on which a transmission belt is fitted. The transmission belt is fixed to the rack 104. One set of rotating rollers is fixed to the drive end of the motor equipment, thereby driving the transmission belt.

[0052] Please see Figure 4 A liquid level sensor 304 is provided at the bottom of the sealing disc 402 to monitor the liquid level of the medicine, and then the height of the filter disc 405 is adjusted by the controller.

[0053] In this embodiment, please refer to Figure 1 and Figure 3 The drive unit includes a bracket 2 fixedly mounted on the housing 1. A second screw 201 is rotatably mounted in the bracket 2. The second screw 201 is fixed to the output end of a drive motor 203 fixedly mounted on the bracket 2. A nut 202 is spirally mounted on the second screw 201. The nut 202 is fixed to a drive seat 205 rotatably mounted on a second support shaft 608 via a drive rod 204. Specifically, during drive, the drive motor 203 is started to drive the second screw 201 to rotate. As the nut 202 moves on the second screw 201, the drive seat 205 can be raised and lowered via the drive rod 204.

[0054] In this embodiment, an outlet 802 is provided on one side of the concentration tank 8, and an inlet 803 is provided on the other side. A negative pressure generator 807 is provided between the inlet 803 and the outlet 802. A condenser 806 is provided between the outlet 802 and the negative pressure generator 807, and a preheating pipe 808 is provided between the inlet 803 and the negative pressure generator 807.

[0055] Please see Figures 7-10 When the negative pressure generator 807 is working, it draws air outward, creating a negative pressure inside the concentration tank 8. At the same time, it causes gas to flow into the concentration tank 8 from the air inlet 803, and the gas inside the concentration tank 8 flows out from the air outlet 802, forming an airflow. It can be seen that the negative pressure generator 807 not only creates a negative pressure in the concentration tank 8, but also creates a flowing airflow inside the concentration tank 8.

[0056] After steam is condensed in condenser 806, it forms a relatively dry gas. This gas is then heated in preheating tube 808 and finally flows back to concentration tank 8, creating a thermodynamic circulation. Because the temperature difference is relatively small after the gas is heated in preheating tube 808 and flows back to concentration tank 8, it does not absorb excessive heat, thus contributing to energy conservation. If the gas flows directly into concentration tank 8 from the outside, the temperature difference is relatively large, and the gas will absorb a large amount of heat, which is detrimental to energy conservation.

[0057] In this embodiment, the discharge pipe 411 is connected to the inlet 804 located on the concentration tank 8, and a solenoid valve is installed at the end of the discharge pipe 411. Specifically, when the medicine is transferred from the extraction tank 4 to the concentration tank 8, the transfer power can be provided by the negative pressure generator 807. That is, the negative pressure generator 807 causes the concentration tank 8 to form a negative pressure. At this time, the air inlet 803 can be closed, and the medicine is drawn into the concentration tank 8 under the action of negative pressure. Thus, the negative pressure generator 807 not only provides negative pressure during concentration but also provides power during the transfer of the medicine. Of course, the medicine can also be transported to the concentration tank 8 by a pump, for example, by installing a pump in the discharge pipe 411.

[0058] Please see Figure 10 A discharge pipe 801 is installed at the bottom of the concentration tank 8, and a solenoid valve is installed between the discharge pipes 801; after the medicine is concentrated, the solenoid valve is opened so that the medicine can be discharged through the discharge pipe 801.

[0059] A pharmaceutical manufacturing device, the manufacturing method of which includes the following steps:

[0060] The drive unit raises the support plate 5 to a preset height, and then places the Chinese medicinal materials on the support plate 5;

[0061] The drive unit drives the carrier plate 5 to return to the bottom of the extraction tank 4, adds clean water to the extraction tank 4 and heats it through the first heating element 7, and stops after boiling for a period of time;

[0062] After the medicine is boiled, the drive unit moves the support plate 5 upward a certain distance, so that the sealing rod 607 is separated from the drain hole 602, and the medicine can be discharged into the conical cavity 701 through the drain hole 602.

[0063] The liquid medicine is discharged into the concentration tank 8 through the discharge pipe 411. The second heating element 805 is started to heat the concentration tank 8 to concentrate the liquid medicine.

[0064] After the drug solution is concentrated, open the solenoid valve so that the drug solution can be discharged through the discharge pipe 801.
