Description

Technical Field

[0001] The present application relates to the technical field of Chinese medicine extraction equipment, and in particular to a Chinese medicine extraction tank. Background Art

[0002] Chinese herbal medicine extraction is one of the important links in Chinese herbal medicine processing. Through extraction, the effective ingredients in Chinese herbal medicine can be separated and made into Chinese medicine preparations for better utilization and application. Traditional Chinese herbal medicine extraction methods mainly include water extraction, alcohol extraction, fat-soluble extraction, etc., but these methods have problems such as low extraction efficiency, complex process, and cumbersome operation. In order to improve the efficiency and quality of Chinese herbal medicine extraction and reduce the consumption of raw materials, Chinese herbal medicine extraction tank technology came into being.

[0003] The Chinese medicine extraction tank is a technical equipment for extracting effective ingredients of Chinese herbal medicines; such as the Chinese medicine extraction tank with publication number CN112742064B, which relates to the technical field of Chinese medicine extraction equipment, the above-mentioned prior art includes: a tank body, a slag discharge door, a lifting mechanism, a self-locking mechanism and a pressurized sealing mechanism, wherein the top of the tank body is provided with a feed port, the bottom is provided with a slag discharge port, the lifting mechanism is provided on the side of the tank body, the lifting mechanism is connected to the slag discharge door and is used to drive the slag discharge door to close and open the slag discharge port, the self-locking mechanism can lock and unlock the relative position of the slag discharge door and the tank body according to the change of the internal temperature of the tank body, and the pressurized sealing mechanism can change the sealing performance between the slag discharge door and the slag discharge port as the internal temperature of the tank body changes by setting the pressurized sealing mechanism. The above-mentioned prior art can avoid the staff from being careless and opening the slag discharge port when the residual liquid and the medicinal residue in the extraction tank are not completely cooled, thereby causing harm to the staff, and solves the problem that the extraction tank is prone to leakage or seepage under the condition of high temperature and high pressure inside the extraction tank.

[0004] However, the above existing technologies still have some defects when it comes to extracting traditional Chinese medicine:

[0005] 1. In the above-mentioned prior art, during the heating process of the Chinese medicinal materials after entering the tank body, the medicinal materials may produce debris in the tank body, which is discharged together with the medicinal liquid after cooling, so that the extracted medicinal liquid is mixed with the medicinal material debris, thereby requiring secondary filtration, thereby affecting the quality of the medicinal liquid and affecting the efficacy.

[0006] 2. In the above-mentioned prior art, the Chinese medicinal materials are heated after entering the tank body, and the tank body is sealed and locked by the self-locking mechanism and the pressurized sealing mechanism to dissolve and extract the Chinese medicinal materials. During the extraction process, the Chinese medicinal materials and water or solution are relatively still, so that the solvent and the Chinese medicinal materials cannot fully contact each other, resulting in uneven distribution of the medicinal ingredients in the extracted liquid.

[0007] 3. In the above-mentioned prior art, in order to avoid opening the slag discharge port before the medicinal liquid is completely cooled and causing harm to the staff, it is necessary to wait for the pressure in the tank to drop to a certain level before opening it after the extraction of the Chinese medicinal materials is completed. Therefore, it is necessary to wait for a long time for the medicinal liquid to cool down after the extraction is completed, thereby affecting the extraction efficiency of the medicinal liquid.

[0008] Based on this, and according to the above viewpoints, the existing technology for Chinese medicine extraction still has room for improvement. Summary of the Invention

At the same time, the sliding rod 446 drives the support ring 445 to move upward through the limiting ring 447, that is, the stirring bracket 441 moves upward synchronously.

[0051] Reference Figure 6 and Figure 7 The tops of the multiple sliding rods 446 pass through the top of the heating cover 21 and are commonly connected to a connecting plate 448 for connecting the multiple sliding rods 446 so that they move synchronously; a U-shaped handle 449 is provided on the top of the connecting plate 448 for controlling the movement of the sliding rods 446.

[0062] In the third step, in order to fully mix the Chinese medicinal materials in the annular tray 431, the annular cover 432 remains stationary under the fixation of the sliding rod 446, so that the stirring bar 434 and the stirring rod 435 installed at the lower end of the annular cover 432 also remain stationary, so that when the annular tray 431 rotates, the Chinese medicinal materials are driven by the stirring rod 435 to be stirred, thereby fully mixing the Chinese medicinal materials in the annular tray 431 with water or solution, and the inclined stirring rod 435 can turn the Chinese medicinal materials to further improve the mixing effect; during the stirring process, the medicinal liquid is filtered through the water filter holes 438 of the annular tray 431 and the annular filter disk 437, while the mixed medicinal material residue is blocked, so that the medicinal material residue cannot enter the medicinal liquid below the annular filter disk 437. By setting the water filter holes 438 with different apertures, multi-stage filtration can be achieved to improve the filtration effect and accelerate the full mixing of the medicinal liquid.

[0063] In the fourth step, after the Chinese medicinal materials in the heating tank 2 are heated and extracted, pull the U-shaped handle 449 to make the connecting plate 448 drive multiple sliding rods 446 to move to the bottom of the heating cover 21. At the same time, the sliding rods 446 drive the stirring bracket 441 through the limiting ring 447 and the support ring 445, so that the annular cover plate 432, the annular tray 431 and the annular filter plate 437 are synchronously moved to the bottom of the heating cover 21, and then fixed by the positioning device 5; the annular tray 431 with the Chinese medicinal materials containing the medicinal liquid is fixed to the bottom of the heating cover 21 by the sliding rod 446, and the annular tray 431 and the annular filter plate 437 at the bottom of the heating cover 21 will drain the medicinal liquid, and the annular tray 431 continues to rotate to speed up the drainage.

[0064] It should be noted that during the stirring process, the medicinal liquid mixed with medicinal material fragments passes through the annular tray 431 and the annular filter plate 437 toward the water filter hole 438 on the inner wall of the stirring bracket 441, thereby entering the support groove 444 and then being filtered through the drainage hole 4411, so that the medicinal material fragments mixed in the medicinal liquid are blocked, thereby further improving the filtration speed and filtration effect.

[0065] While the annular tray 431 is draining the Chinese medicinal materials containing the medicinal liquid, the drainage hole 4411 will discharge the medicinal liquid in the supporting groove 444 into the heating tank 2, and block the medicinal material debris mixed in the medicinal liquid to improve the filtering effect.

The medicine at the bottom of the heating tank 2 enters the circulation pipe 61 through the circulation inlet 62 and then flows out from the circulation outlet 63 to the top of the heating tank 2, so that the medicine liquid repeatedly contacts the Chinese medicinal materials in the medicinal material separation device 4; a circulation support rod 64 is provided in the circulation pipe 61, and the lower end of the circulation support rod 64 passes through the bottom of the protection tank 1 and is connected to the driving device 9. The part of the circulation support rod 64 located in the circulation pipe 61 is provided with a spiral blade 65, and the circulation support rod 64 is driven to rotate by the driving device 9, thereby driving the spiral blade 65 to rotate, so as to facilitate the transportation of the medicine at the bottom of the circulation pipe 61 to the top of the circulation pipe 61.

[0067] A conical surface 23 convex from the four sides to the middle is provided at the bottom of the heating tank 2, which is used to guide the medicine to flow to the edge of the heating tank 2; a drainage bevel 66 is provided on the conical surface 23 and located between multiple circulation pipes 61, and a drainage bevel 67 is provided on the drainage bevel 66 for guiding the medicine into the circulation inlet 62, which is used to guide the medicine into the circulation inlet 62.

[0068] During the specific implementation process, the driving device 9 drives the medicinal material separation device 4 to rotate so that the water or solution in the heating tank 2 is fully mixed and contacted with the Chinese medicinal materials in the annular tray 431. When the driving device 9 is started, it will drive the circulation support rod 64 to rotate, so that the spiral blade 65 transports the medicinal liquid at the circulation inlet 62 to the circulation outlet 63, so that the medicinal liquid flows into the top of the annular cover plate 432 through the circulation outlet 63, so that the medicinal liquid passes through the medicinal material separation device 4 again, so as to fully contact with the Chinese medicinal materials in the annular tray 431 again, thereby improving the extraction effect of the Chinese medicinal materials; then, through the conical surface 23 at the bottom of the heating tank 2 and the drainage inclined surface 67 on the drainage inclined block 66, the medicinal liquid is converged to the circulation inlet 62 for circulation, thereby realizing repeated circulation of the medicinal liquid and contact with the Chinese medicinal materials in the annular tray 431, and making the medicinal liquid in the heating tank 2 fully mixed.

[0069] Reference Figure 6 and Figure 7The positioning device 5 includes a positioning block 51 located on one side of the sliding rod 446. Several positioning blocks 51 are installed on the heating cover 21 and correspond to the sliding rod 446 one by one, for supporting the connecting plate 448; a positioning rod 52 is passed through the positioning block 51 and slides in the direction of the sliding rod 446 to position the sliding rod 446; several positioning rods 52 are commonly connected to a positioning bracket 53, and the positioning bracket 53 is slidably set on the heating cover 21 to enable several positioning rods 52 to move synchronously; a positioning support block 54 is provided on the heating cover 21, and a positioning spring 55 is connected between the positioning bracket 53 and the positioning support block 54 to drive the positioning rod 52 to fix the sliding rod 446; the positioning spring 55 is used to drive the positioning rod 52 to slide in the direction of the sliding rod 446, and a positioning hole 56 (at Figure 5 ), used to cooperate with the positioning rod 52 for positioning.

[0070] During the specific implementation process, the Chinese medicinal materials are stirred in the annular tray 431 by the stirring rod 435 on the annular cover 432 to ensure that the Chinese medicinal materials are fully mixed; at the same time, the medicinal liquid is transported in the heating tank 2 by the spiral blade 65 on the circulation support rod 64, so that the medicinal liquid flows from the circulation inlet 62 to the circulation outlet 63 and circulates continuously for further mixing. When the medicinal materials are extracted under the stirring and mixing and the medicinal liquid is circulated and mixed; the U-shaped handle 449 is pulled to make the connecting plate 448 drive multiple sliding rods 446 to move toward the bottom of the heating cover 21, and at the same time, the sliding rod 446 drives the stirring bracket 441 to move upward synchronously through the limit ring 447 and the support ring 445, so that the annular cover 432, the annular tray 431 and the annular filter plate 437 are moved synchronously to the bottom of the heating cover 21.

[0071] At this time, the spring on the positioning support block 54 pushes the positioning bracket 53, so that the positioning rod 52 is inserted into the positioning hole 56 to position the sliding rod 446. The annular tray 431 with the Chinese medicinal materials containing the medicinal liquid is fixed to the bottom of the heating cover 21 by the sliding rod 446. The annular tray 431 and the annular filter plate 437 at the bottom of the heating cover 21 will drain the medicinal liquid.

[0072] Reference Figures 6 to 8The pressure relief device 7 includes a pressure relief pipe 71, which passes through the partition plate 12 and the protection tank 1 in sequence from the inner wall of the heating tank 2 and extends to the outside of the protection tank 1.

[0073] During the specific implementation process, before putting the medicinal materials in, it is necessary to rotate the pressure relief knob 75 so that the pressure relief rod 73 and the solid section of the pressure relief tube 71 are threadedly engaged, so that the pressure relief rod 73 pushes the pressure relief piston 74 to block the pressure relief tube 71.

[0074] With the cooperation of the sliding assembly 44, the medicinal material separation device 4 is moved to the top of the heating tank 2, and the medicinal material separation device 4 is fixed to the bottom of the heating cover 21 by the positioning device 5; at this time, the pressure relief knob 75 is rotated to unscrew the thread on the pressure relief rod 73 from the solid section of the pressure relief tube 71. At this time, the pressure relief rod 73 loses the thread fixation of the solid section of the pressure relief tube 71, and driven by the pressure in the heating tank 2, the pressure relief piston 74 drives the pressure relief rod 73 to move toward the pressure relief chamber 13 until the pressure relief piston 74 moves to the solid section of the pressure relief tube 71 and does not affect the pressure relief of the pressure relief hole 72; at this time, the gas in the heating tank 2 enters the pressure relief chamber 13 through the pressure relief tube 71 and the pressure relief hole 72, and is thereby condensed through the cooling chamber 14.

[0079] The condensed liquid medicine in the pressure relief chamber 13 is directed to the diverter pipe 86 through the annular inclined surface 85 on the annular drainage block 84. The diverter valve 87 is opened to allow the liquid medicine to pass through the diverter pipe 86 into the liquid medicine discharge pipe 82, thereby discharging the condensed liquid medicine in the pressure relief chamber 13 and the liquid medicine in the heating tank together.
