Description

Technical Field

[0001] This invention belongs to the field of traditional Chinese medicine extraction technology, specifically relating to a traditional Chinese medicine soaking and reprocessing extraction device and extraction method. Background Technology

[0002] Traditional Chinese medicine (TCM) refers to drugs made from natural substances such as plants, animals, and minerals through processing. It holds an important position in traditional Chinese medicine, guiding the collection, preparation, and formulation of drugs according to traditional Chinese medical theories, explaining their mechanisms of action, and guiding clinical application. TCM mainly originates from natural medicines and their processed products. TCM extraction aims to maximize the extraction of the effective components from medicinal materials, improving the quality and clinical efficacy of TCM preparations, and maximizing the therapeutic effect of TCM. While existing TCM extraction devices and methods are diverse, they generally involve a single processing or simple multiple boiling processes, relying on manual control, resulting in low utilization rates and low automation levels.

[0003] Patent document CN109260758B discloses a rapid traditional Chinese medicine extraction device, "comprising a main body, with a rotating shaft rotatably mounted on the upper end of the main body; a stirring rod welded onto the rotating shaft; a rotating rod mounted on the rotating shaft; a reciprocating mechanism at the bottom of the rotating rod to drive the extraction cylinder to move up and down; a first filter screen, a second filter screen, and a third filter screen sequentially arranged at the bottom of the extraction cylinder; a filter port on the left side of the main body, corresponding to the bottom of the first, second, and third filter screens; a cleaning box assembled on the left side of the main body; a feed inlet on the cleaning box for communication with the filter port on the main body; and a three-layer mesh screen identical to the first, second, and third filter screens inside the cleaning box." This device only extracts the traditional Chinese medicine materials once, resulting in low utilization of the medicinal materials, and it lacks corresponding automated control devices, resulting in a low degree of automation.

[0013] The present invention also provides an extraction method for the aforementioned Chinese herbal medicine soaking and reprocessing extraction device, the method comprising a Chinese herbal medicine soaking method S1 and a re-pulverization method S2;

[0014] Among them, the soaking method S1 for Chinese medicinal materials includes the following steps;

[0015] S11, the pre-crushed Chinese medicinal materials are added into the soaking tank through the first feed inlet;

[0016] S12, the liquid at a certain temperature is added to the soaking tank through the feed pipe assembly. When the height of the solution in the soaking tank reaches the set value of the liquid level sensor, the liquid level sensor sends a signal to the PLC control system to close the first solenoid valve.

[0017] S13, after the Chinese medicinal materials in step S11 and the liquid in step S12 have been soaked in the soaking tank for a certain period of time, a signal is sent to the PLC control system to open the second solenoid valve, and the upper and middle layer solution in the soaking tank flows into the medicine storage tank assembly through the first drain pipe.

[0018] S14. After a preset time, when no solution flows out of the first drain pipe, a signal is sent to the PLC control system to close the second solenoid valve and start the motor to rotate the stirring paddle assembly, so that the remaining solution in the soaking tank is stirred evenly.

[0019] Wherein: the re-crushing process S2 includes the following steps;

[0020] S21, after the stirring paddle assembly rotates for a certain period of time in step S14 above, the third and fourth solenoid valves are opened, and the solution that is stirred evenly in the soaking tank enters the first reprocessing component through the first discharge pipe. After a preset time, the fourth solenoid valve is closed and the fifth solenoid valve is opened, and the solution that is stirred evenly in the soaking tank enters the second reprocessing component through the second discharge pipe. After a preset time, the third and fifth solenoid valves are closed.

[0021] S22, when the fourth solenoid valve in step S21 is closed, the first drive assembly is started, and its corresponding piston moves upward, pushing the solution inside the first reprocessing assembly upward. When the first drive assembly is fully extended, the motor of the first reducer is started by the PLC control system, which drives the rotary cutting assembly inside the first reprocessing assembly to rotate. When the rotary cutting assembly rotates, the mixture containing the drug residue will be further crushed under the combined action of centrifugal force and irregular swirling flow.

[0022] S23, after the rotary cutting assembly in step S22 has rotated to the predetermined time, the motor of the first reducer is turned off and the sixth solenoid valve is opened. The solution to be reprocessed in the first reprocessing assembly flows into the drug storage tank assembly through the first Y-type filter.

[0023] S24, when the fifth solenoid valve in step S21 is closed, the second drive assembly is activated, and its corresponding piston moves upward, pushing the solution inside the second reprocessing assembly upward. When the second drive assembly is fully extended, the motor of the second reducer is activated by the PLC control system, driving the rotary cutting assembly inside the second reprocessing assembly to rotate. When the rotary cutting assembly rotates, the mixture containing the drug residue will be further crushed under the combined action of centrifugal force and irregular swirling flow.

[0024] S25, after the rotary cutting assembly in step S24 has rotated to the predetermined time, the motor of the second reducer is turned off and the seventh solenoid valve is opened. The solution to be reprocessed in the second reprocessing assembly flows into the drug storage tank assembly through the second Y-type filter.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) The present invention provides a traditional Chinese medicine soaking and reprocessing extraction device, which, through the setting of soaking tank assembly, feeding pipe assembly, first discharge pipe, medicine storage tank assembly, discharge tee assembly, first reprocessing assembly, third discharge pipe, second reprocessing assembly, fourth discharge pipe and PLC control system, obtains the first traditional Chinese medicine raw liquid by soaking, and then further crushes the medicine residue and mixes it evenly through the reprocessing assembly, and performs a second extraction, thereby improving the utilization rate of traditional Chinese medicine materials.

[0027] (2) The present invention provides a traditional Chinese medicine soaking and reprocessing extraction device, in which different specifications of cutters are set in the spiral groove of the rotating shaft. Under the combined action of centrifugal force and irregular swirling flow, the mixture containing medicinal residue will collide with the cutters in multiple directions, and the medicinal residue will be further crushed.

[0028] (3) The present invention provides a traditional Chinese medicine soaking and reprocessing extraction device, which can add the traditional Chinese medicine residue in the Y-type filter into the soaking tank through the first feed port for reuse, thereby improving the utilization rate of traditional Chinese medicine materials.

[0029] (4) The Chinese herbal medicine soaking and reprocessing extraction device provided by the present invention has a high degree of automation. The motor, reducer, drive components, and solenoid valves are all connected to the PLC control system.

[0030] (5) The Chinese medicine soaking and reprocessing extraction device provided by the present invention has the following characteristics: In order to improve the secondary crushing effect, the inner diameter of the first reprocessing cylinder and the second reprocessing cylinder are not much different from the outer diameter of the rotating shaft. If the material is fed from the top of the first reprocessing cylinder and the second reprocessing cylinder, it is easy to get clogged. However, the present invention feeds the material from the bottom of the rotating shaft and uses a drive component to push the piston to drive the material upward, which effectively solves the clogging problem.

[0031] (6) The Chinese herbal medicine soaking and reprocessing extraction device provided by the present invention has gaps a in both the first reprocessing component and the second reprocessing component, which effectively eliminates the possible accumulation of material in the discharge of the first reprocessing component and the second reprocessing component.

[0040] It should be understood that, in the description of the invention, it should be noted that, unless otherwise explicitly specified and limited, the terms “installation,” “connection,” and “linking” should be interpreted broadly.

[0041] Example 1

[0042] See appendix Figures 1 to 5 This embodiment provides a traditional Chinese medicine soaking and reprocessing extraction device, which includes a soaking tank assembly 100, a feed pipe assembly 200, a first drain pipe 300, a medicine storage tank assembly 400, a discharge tee assembly 500, a first reprocessing assembly 600, a third discharge pipe 700, a second reprocessing assembly 800, a fourth discharge pipe 900, and a PLC control system.

The stirring assembly 120 is driven by a motor 121. A stirring paddle assembly 122 is provided at the tail end of the stirring assembly 120 that extends into the soaking tank body 110. The highest point of the stirring paddle assembly 122 is lower than the lowest point of the first discharge port 111, so that the liquid discharged through the first drain pipe 300 after long-term soaking does not contain large solid particles.

[0046] The feed pipe assembly 200 is located on one side of the soaking tank body 110 and is connected to it. The feed pipe assembly 200 is equipped with a first solenoid valve 201, and the required liquid is added into the soaking tank body 110 through the feed pipe assembly 200.

[0047] One end of the first drain pipe 300 is connected to the soaking tank body 110, and the other end is connected to the medicine storage tank assembly 400. A second solenoid valve 301 is installed on the first drain pipe 300.

[0048] The discharge tee assembly 500 is connected to the soaking tank body 110, the first reprocessing assembly 600, and the second reprocessing assembly 800 respectively. The discharge tee assembly 500 includes a tee discharge main pipe 510, a first discharge pipe 520, and a second discharge pipe 530.

A third solenoid valve 511 is installed on the tee discharge main pipe 510, a fourth solenoid valve 521 is installed on the first discharge pipe 520, and a fifth solenoid valve 531 is installed on the second discharge pipe 530.

[0049] The first reprocessing assembly 600 includes a first reducer 610, a coupling 620, a support plate assembly 630, a first reprocessing cylinder 640, a rotary cutting assembly, a piston 670, and a first drive assembly 680. The top diameter of the first reprocessing cylinder 640 is larger than the bottom diameter. The support plate assembly 630 is located at the top of the first reprocessing cylinder 640. A fixing bracket (not shown in the figure) can be provided around the support plate assembly 630 for fixing the first reprocessing assembly 600. The first reducer 610 is located at the top of the support plate assembly 630, and the output shaft end of the first reducer 610 extends into the interior of the first reprocessing cylinder 640. The coupling 620 is located inside the first reprocessing cylinder 640. One end of the coupling 620 is connected to the output shaft end of the first reducer 610, and the other end is connected to the rotary cutting assembly. The piston 670 is located inside the first reprocessing cylinder 640 and is fixedly connected to the first drive assembly 680.

[0050] The rotary cutting assembly includes a rotating shaft 650 and a cutter 660. The top of the rotating shaft 650 is provided with a coupling connection end 651, and the periphery of the rotating shaft 650 is provided with several spiral grooves 652. The cutter 660 is located in the spiral grooves 652. When the rotary cutting assembly rotates, the mixture containing the dregs will be further crushed under the combined action of centrifugal force and irregular swirling flow.

[0051] The first reprocessing cylinder 640 is provided with a second feed port 641 and a third discharge port 642. The height of the second feed port 641 is lower than the height of the third discharge port 642. When the first drive assembly 680 is fully extended and drives the piston 670 to move upward, the highest point of the piston 670 is located above the lowest point of the third discharge port 642, i.e., dimension a in the figure. This effectively eliminates the possible accumulation of material in the discharge of the first reprocessing assembly 600.

[0052] The second reprocessing assembly 800 includes a second reducer 810, a coupling 620, a support plate assembly 630, a second reprocessing cylinder 820, a rotary cutting assembly, a piston 670, and a second drive assembly 830. The second reprocessing cylinder 820 is provided with a third feed inlet 821 and a fourth discharge outlet 822. The height of the third feed inlet 821 is lower than the height of the fourth discharge outlet 822. When the second drive assembly 830 is fully extended and drives its corresponding piston 670 to move upward, the highest point of the piston 670 is located above the lowest point of the fourth discharge outlet 822. The second reprocessing cylinder 820 and the first reprocessing cylinder 640 are symmetrically distributed about the axis of the stirring assembly 120.

[0053] One end of the third discharge pipe 700 is connected to the first reprocessing component 600, and the other end is connected to the medicine storage tank component 400; a sixth solenoid valve 701 is installed on the third discharge pipe 700, and a first Y-type filter 702 is installed at the rear end of the sixth solenoid valve 701.

[0054] One end of the fourth discharge pipe 900 is connected to the second reprocessing component 800, and the other end is connected to the medicine storage tank component 400. A seventh solenoid valve 901 is installed on the fourth discharge pipe 900, and a second Y-type filter 902 is installed at the rear end of the seventh solenoid valve 901.

[0055] This embodiment also provides an extraction method for a traditional Chinese medicine soaking and reprocessing extraction device, which includes a traditional Chinese medicine soaking method S1 and a re-pulverizing treatment method S2;

[0056] Among them, the soaking method S1 for Chinese medicinal materials includes the following steps;

[0057] S11, the pre-crushed Chinese medicinal materials are added into the soaking tank 110 through the first feed inlet 130;

[0058] S12, the liquid at a certain temperature is added into the soaking tank 110 through the feed pipe assembly 200. When the height of the solution in the soaking tank 110 reaches the set value of the liquid level sensor 140, the liquid level sensor sends a signal to the PLC control system to close the first solenoid valve 201.

[0059] S13, after the Chinese medicinal materials from step S11 and the liquid from step S12 have been soaked in the soaking tank 110 for a certain period of time, a signal is sent to the PLC control system to open the second solenoid valve 301, and the upper and middle layer solution in the soaking tank 110 flows into the medicine storage tank assembly 400 through the first drain pipe 300.

[0060] S14. After a preset time, when no solution flows out of the first drain pipe 300, a signal is sent to the PLC control system to close the second solenoid valve 301 and start the motor 121 to make the stirring paddle assembly 122 rotate, so that the remaining solution in the soaking tank 110 is stirred evenly.

[0061] Wherein: the re-crushing process S2 includes the following steps;

[0062] S21, after the stirring paddle assembly 122 rotates for a certain period of time in step S14 above, the third solenoid valve 511 and the fourth solenoid valve 521 are opened. The solution that is stirred evenly in the soaking tank 110 enters the first reprocessing assembly 600 through the first discharge pipe 520. After a preset time, the fourth solenoid valve 521 is closed and the fifth solenoid valve 531 is opened. The solution that is stirred evenly in the soaking tank 110 enters the second reprocessing assembly 800 through the second discharge pipe 530. After a preset time, the third solenoid valve 511 and the fifth solenoid valve 531 are closed.

[0063] S22, when the fourth solenoid valve 521 in step S21 is closed, the first drive assembly 680 is activated, and its corresponding piston 670 moves upward, pushing the solution inside the first reprocessing assembly 600 upward. When the first drive assembly 680 is fully extended, the motor of the first reducer 610 is activated by the PLC control system, driving the rotary cutting assembly inside the first reprocessing assembly 600 to rotate. When the rotary cutting assembly rotates, the mixture containing the drug residue will be further crushed under the combined action of centrifugal force and irregular swirling flow.

[0064] S23, after the rotary cutting assembly in step S22 has rotated to the predetermined time, the motor of the first reducer 610 is turned off and the sixth solenoid valve 701 is opened. The solution that has been reprocessed in the first reprocessing assembly 600 flows into the medicine storage tank assembly 400 through the first Y-type filter 702.

[0065] S24, when the fifth solenoid valve 531 in step S21 is closed, the second drive assembly 830 is activated, and its corresponding piston 670 moves upward, pushing the solution inside the second reprocessing assembly 800 upward. When the second drive assembly 830 is fully extended, the motor of the second reducer 810 is activated by the PLC control system, driving the rotary cutting assembly inside the second reprocessing assembly 800 to rotate. When the rotary cutting assembly rotates, the mixture containing the drug residue will be further crushed under the combined action of centrifugal force and irregular swirling flow.

[0066] S25, after the rotary cutting assembly in step S24 has rotated to the predetermined time, the motor of the second reducer 810 is turned off and the seventh solenoid valve 901 is opened. The solution that has been reprocessed in the second reprocessing assembly 800 flows into the medicine storage tank assembly 400 through the second Y-type filter 902.

[0067] It is easy to understand that the solution that enters the drug storage tank assembly 400 through the above steps S13, S23 and S25 will be further mixed before entering the next process.

[0068] This embodiment shows a case where a soaking tank assembly 100 is followed by two reprocessing assemblies. However, in practice, the number of reprocessing assemblies can be determined based on the remaining solution in the soaking tank body 110 and the capacity of the reprocessing assemblies. Furthermore, the Chinese herbal medicine residue filtered in the Y-type filter can also be added back into the soaking tank body 110 through the first feed port 130 for reuse, thereby improving the utilization rate of Chinese herbal medicines.

[0069] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
