Description

Technical Field

[0001] The present invention relates to the technical field of Chinese medicine processing, and more specifically, to a processing technology and equipment based on Chinese medicine pieces. Background Art

[0002] Processing is the process of processing Chinese herbal medicines into medicines. Processing can eliminate or reduce the toxicity of drugs, improve efficacy and facilitate the storage of drugs.

[0003] The relevant Chinese medicine processing method usually involves washing and cutting the raw materials of the Chinese medicine into segments, then crushing and grinding the segments to obtain powder, and using a heating container to remove moisture from the powder at high temperature so that harmful chemicals in the Chinese medicine can denature or volatilize to obtain processed Chinese medicine slices.

[0004] In the process of processing and grinding traditional medicinal materials, a screen is needed for filtering in order to obtain particles of uniform size. However, during the grinding process, the particles are easy to block the screen, causing the subsequent fine drugs to be ground unable to be separated from the solid drugs in time, which not only leads to a slow discharge speed during the grinding process, but also greatly reduces the grinding effect; In addition, the powder obtained through a simple crushing and grinding process is still not fine enough, so some processing techniques add an ultrasonic wall breaking treatment after the grinding process. The obtained powder is made into an aqueous solution and introduced into an ultrasonic treatment box for unified treatment. This unified ultrasonic wall breaking treatment still has some disadvantages. For example, the next wall breaking process is usually carried out after the grinding process is completed. The previous and subsequent processes are not connected, the operation process is long, the unified treatment volume is large, and the wall breaking effect is also not good.

[0005] To this end, we proposed a processing technology and equipment based on Chinese herbal medicine slices to address the above problems. Summary of the invention

[0006] The purpose of the present invention is to solve the existing practical problems. Compared with the existing technology, a processing process and equipment based on Chinese herbal medicine slices are provided. A new grinding device is formed by adding a grinding cylinder and a moving grinding sleeve to the grinding structure composed of a traditional grinding roller and a fixed grinding sleeve.

At the same time, the aqueous solution is sprayed out from the spray port on the spray column by using a water supply structure, and the sprayed water flow impacts up and down respectively. On the one hand, a wet grinding environment is provided to improve the grinding effect. On the other hand, it is conducive to dispersing the ground material blocked in the coarse filter hole and the fine filter hole, increasing the discharge speed. The fine ground material falls directly into the ultrasonic processing device below with the water flow, so that a small-volume ultrasonic wall breaking process is directly carried out layer by layer during the grinding process, and the bottom layer of fine ground aqueous solution is discharged one by one at a preset time, thereby improving the ultrasonic wall breaking effect.

[0011] Furthermore, the water supply structure includes a docking sleeve embedded in the inner wall of the operating box and connected to the end of the rotating ring.

A plurality of groups of staggered grinding columns 92 and injection columns 93 are rotatably installed on the end walls corresponding to the rotating ring 91 and the fixed grinding sleeve 4.

[0021] The end of the operating box 1 away from the feed port 6 is embedded with a driving structure for synchronously rotating the grinding roller 3 and the rotating ring 91. The driving structure includes a driving motor 10 fixedly mounted on the outer end wall of the operating box 1. The driving end of the driving motor 10 passes through the operating box 1 and is fixedly connected to the axial end of the grinding roller 3. A toothed belt 911 is fixedly installed on the inner end wall of the rotating ring 91 near the driving motor 10. A rotating shaft located between the driving shaft of the driving motor 10 and the toothed belt 911 is rotatably installed on the inner wall of the operation box 1.

The coarse ground materials obtained by the cooperation between the grinding roller 3 and the fixed grinding sleeve 4 fall into the annular grinding chamber through the coarse filter hole 401. During the rotation of the rotating ring 91, the multiple groups of grinding columns 92 and the jet columns 93 on the end wall thereof perform secondary deep grinding on the coarse ground materials during the rolling process of the annular grinding chamber.

[0022] Embodiment 2: Based on Embodiment 1, this embodiment adds a water supply structure connected to the spray column 93 on the side of the grinding device away from the driving structure, as follows: See also Figure 10-11 as well as Figure 13-14 The outer end wall of the injection column 93 is provided with a plurality of injection ports 931 connected to the interior thereof, the end wall of one side of the rotating ring 91 is provided with a plurality of connecting holes 912 connected to the interior of the injection column 93, and the end of the operation box 1 close to the connecting holes 912 is provided with a water supply structure corresponding to the position of the blanking port and connected to the plurality of connecting holes 912; The water supply structure includes a docking sleeve 12 which is embedded in the inner wall of the operating box 1 and connected to the end of the rotating ring 91. The docking sleeve 12 is provided with a docking groove with an inner end opening. The docking groove is sealed and fitted with the end of the rotating ring 91. The outer end of the docking sleeve 12 is connected to a water pump 14 installed at the end of the operating box 1 through a spray pipe 13. The water pump 14 is connected to the water supply source through an external pipe. During the secondary grinding process, the water supply structure is used to transmit the aqueous solution to multiple spray columns 93 in the annular grinding chamber, and the aqueous solution is sprayed out from multiple spray ports 931 on the spray columns 93. The sprayed water flows impact up and down respectively, which on the one hand provide a wet grinding environment, and on the other hand disperse the particulate matter blocked in the coarse filter holes 401 and the fine filter holes 211, thereby increasing the discharge speed.

[0023] Embodiment 3: Based on Embodiments 1 and 2, this embodiment further includes an ultrasonic treatment device below the material discharge port, which is used to perform ultrasonic wall breaking treatment on the finely ground aqueous solution discharged from the plurality of fine filter holes 211, as follows: See also Figure 3-Figure 4 The bottom end of the operation box 1 is provided with an ultrasonic processing device whose top end is connected to the blanking port. The ultrasonic processing device includes an ultrasonic vibration box 15 connected to the blanking port and a wall breaking box 17 installed in the ultrasonic vibration box 15 and connected to the fine filter hole 211. The outer end of the ultrasonic vibration box 15 is provided with a drainage pipe 16 connected to the wall breaking box 17. See also Figure 15-16 A plurality of processing chambers are provided inside the wall-breaking box 17, and a plurality of diverter plates 18 distributed vertically are fixedly connected to each processing chamber, and the diverter plates 18 divide the processing chamber into a plurality of upper and lower sub-processing chambers, and a drainage valve connected to the sub-processing chamber is embedded and installed on each diverter plate 18, and a displacement sensor is installed at the top of each sub-processing chamber, and the drainage pipe 16 is connected to the lowermost sub-processing chamber through the diverter pipe; The finely ground material falls directly into the ultrasonic treatment device below with the water flow for ultrasonic wall breaking treatment. In this process, the finely ground aqueous solution is divided and falls into multiple treatment chambers, and is injected into multiple sub-treatment chambers layer by layer from top to bottom. The liquid level sensor on the top of the sub-treatment chamber is used to detect the liquid level. When the finely ground aqueous solution in the sub-treatment chamber reaches the liquid level standard, the drain valve on the top of the sub-treatment chamber is closed, so that the finely ground aqueous solution in the bottom sub-treatment chamber is discharged outwardly through the drain pipe 16 within a preset time. When the finely ground aqueous solution in the bottom sub-treatment chamber is completely drained, the drainage time of the bottom sub-treatment chamber is calculated in advance. When the drainage time is reached, the drain valves on the tops of the other several upper parts are opened to drain the finely ground aqueous solution in the upper sub-treatment chamber layer by layer. This cycle allows the finely ground aqueous solution that continuously falls into the treatment chamber to undergo ultrasonic wall breaking treatment within a preset time. A drain valve is added at the top of each sub-processing chamber. After the liquid level sensor detects that the liquid level in the sub-processing chamber reaches the standard liquid level, the drain valve is closed, and the sub-processing chamber is in a closed state, thereby effectively preventing the finely ground aqueous solutions in each sub-processing chamber from flowing mutually, so that the finely ground aqueous solutions that continuously fall into the processing chamber can be subjected to ultrasonic wall breaking treatment within the same preset time. Compared with uniform ultrasonic treatment in a large volume, a small volume synchronous ultrasonic treatment is adopted, and the bottom layer of finely ground aqueous solution is discharged at a preset time, and the finely ground aqueous solution is discharged layer by layer from top to bottom, which effectively improves the ultrasonic wall breaking treatment effect; What needs to be noted during the ultrasonic wall breaking treatment process is that the aqueous solution mixed with the finely ground material grinding roller 3 sprayed outward by the water supply structure falls into the sub-treatment chamber, and the aqueous solution spraying amount, speed, treatment chamber depth, and preset discharge time of the lowest sub-treatment chamber are all set according to actual needs to ensure that the finely ground aqueous solution will not overflow from the wall breaking box 17 under the premise that the finely ground aqueous solution is fully ultrasonically broken.

[0024] According to Examples 1, 2 and 3, the present invention further proposes a processing process based on Chinese herbal medicine pieces, comprising the following steps: Step 1: First, the cleaned Chinese medicinal materials are cut into segments and crushed by a crushing device. The crushed Chinese medicinal materials fall into the primary grinding space between the grinding roller 3 and the fixed grinding sleeve 4 through the discharge hole 501 for grinding. The coarse ground material obtained by the cooperation between the grinding roller 3 and the fixed grinding sleeve 4 falls into the annular grinding chamber through the coarse filter hole 401. The grinding column 92 and the injection column 93 perform secondary grinding on the coarse ground material in the rolling friction process of the annular grinding chamber to obtain fine ground material. Step 2: During the secondary grinding process, the water supply structure is used to transfer the aqueous solution to the multiple injection columns 93 in the annular grinding chamber, and the aqueous solution is sprayed out from the multiple injection ports 931 on the injection columns 93. The sprayed water flows impact upward and downward respectively, which not only provides a wet grinding environment, but also disperses the particles blocked in the coarse filter holes 401 and the fine filter holes 211, thereby increasing the discharge speed. Step 3: The finely ground material falls directly into the ultrasonic treatment device below with the water flow for ultrasonic wall breaking treatment. In this process, the finely ground aqueous solution is divided and falls into multiple treatment chambers, and is injected into multiple sub-treatment chambers layer by layer from top to bottom; In this process, the liquid level sensor at the top of the sub-processing chamber is used to detect the liquid level. When the finely ground aqueous solution in the sub-processing chamber reaches the liquid level standard, the drain valve at the top of the sub-processing chamber is closed, so that the finely ground aqueous solution in the bottom sub-processing chamber is discharged outwardly through the discharge pipe 16 within a preset time. When the finely ground aqueous solution at the bottom is completely discharged, the drain valve at the top is opened to discharge the finely ground aqueous solution in the upper sub-processing chamber downward, and this cycle is repeated, so that the finely ground aqueous solution that continuously falls into the processing chamber can be subjected to ultrasonic wall breaking treatment within a preset time. Step 4: vacuum-dry the finely ground aqueous solution treated with ultrasound discharged from the discharge pipe 16 to obtain fine solid powder, thereby completing the preparation of Chinese herbal medicine slices.

[0025] In summary, the present invention is a new grinding device formed by adding a grinding cylinder 2 and a dynamic grinding sleeve 9 to a grinding structure composed of a traditional grinding roller 3 and a fixed grinding sleeve 4. The grinding cylinder 2 is located outside the fixed grinding sleeve 4 and is coaxially arranged therewith, and the dynamic grinding sleeve 9 is rotatably installed in an annular grinding chamber between the lower ring sleeve 21 and the fixed grinding sleeve 4. During operation, the coarse grinding material obtained by the cooperation between the grinding roller 3 and the fixed grinding sleeve 4 falls into the annular grinding chamber through the coarse filter hole 401, and the dynamic grinding sleeve 9 includes a rotating ring 91 and grinding columns 92 and a jet column 93 which are staggered and rotated and distributed on the rotating ring 91. The grinding columns 92 and the jet column 93 perform secondary grinding on the coarse grinding material during the rolling process in the annular grinding chamber. During the secondary grinding process, the plurality of spray columns 93 located in the annular grinding chamber are connected to and communicated with the docking sleeve 12, and the aqueous solution is sprayed out from the spray port 931 on the spray column 93 by using the water supply structure. The sprayed water flow impacts up and down respectively, which, on the one hand, provides a wet grinding environment and improves the grinding effect, and on the other hand, is conducive to dispersing the non-material blocking the coarse filter hole 401 and the fine filter hole 211, thereby increasing the discharge speed; The finely ground material falls directly into the ultrasonic processing device below with the water flow for ultrasonic wall breaking treatment. In this process, the finely ground aqueous solution is injected into multiple sub-processing chambers layer by layer from top to bottom. The liquid level sensor on the top of the sub-processing chamber is used to detect the liquid level. When the finely ground aqueous solution in the sub-processing chamber reaches the liquid level standard, the top drain valve is closed, and the finely ground aqueous solution in the bottom sub-processing chamber is discharged outward through the drain pipe 16 within a preset time. When the finely ground aqueous solution at the bottom is drained, all the drain valves on the top are opened, and the finely ground aqueous solution is discharged layer by layer from top to bottom to replenish the sub-processor below. When the liquid level sensor on the top of the sub-processing chamber detects that the liquid level has reached the standard signal, the top drain valve is closed again. Such a cycle allows the finely ground aqueous solution that continuously falls into the processing chamber to be ultrasonically broken within the same preset time. Compared with uniform ultrasonic treatment in a large volume, a small volume synchronous ultrasonic treatment is adopted, and the bottom layer of finely ground aqueous solution is discharged at a preset time, and discharged layer by layer from top to bottom, effectively improving the ultrasonic wall breaking treatment effect. Finally, the ultrasonically treated finely ground aqueous solution discharged from the discharge pipe 16 is vacuum dried to obtain a fine solid powder, thereby completing the preparation of Chinese herbal medicine slices.
