Description

Technical Field

[0001] The present invention relates to the field of traditional Chinese medicine screening, and specifically to a screening device for traditional Chinese medicine processing. Background Technique

[0002] The screening device for traditional Chinese medicine processing refers to a mechanical device specifically used for material screening during the processing of traditional Chinese medicine. This device classifies and screens traditional Chinese medicine according to characteristics such as particle size and shape through a sieve mesh to ensure the quality and uniformity of traditional Chinese medicine. In the industrial chain of traditional Chinese medicine processing, the screening device plays a crucial role. It can improve the processing efficiency and product quality of traditional Chinese medicine, and also helps to remove impurities and unqualified products. In addition, modern traditional Chinese medicine screening devices also have the characteristics of automation and intelligence, which can reduce manual operations, improve production safety and hygiene standards;

[0003] Chinese Patent with publication number CN216282393U discloses a screening device for excellent varieties of traditional Chinese medicine, including a storage box. A humidity sensor is installed on one side inside the storage box, and a drying structure is arranged inside the storage box. On the other side of the top of the fixed base, a classification sieve box is installed. The drying box is first subjected to certain installation treatment, and certain air flow control work is completed under the connection of its air inlet pipe. After the air flow reaches the inside of the drying box, it completes certain power-on treatment at the position of the temperature-raising component, so that after it is powered on, it completes certain temperature-raising treatment, and the air flow completes the overall temperature-raising work after passing through the temperature-raising plate. The heated air flow finally reaches the inside of the classification sieve box at the position of the diversion pipe, thus completing a good drying work, and thus greatly improving its overall functional working ability.

[0004] During the screening process of the above-mentioned patent screening device, the classification sieve mesh used for screening cannot be cleaned. When cleaning the classification sieve mesh, the operation of the device needs to be stopped, and the input of traditional Chinese medicine into the device needs to be stopped. When cleaning the classification sieve mesh, the screening of traditional Chinese medicine will stop, affecting the screening efficiency of traditional Chinese medicine. Summary of the Invention

[0005] The purpose of the present invention is to provide a screening device for traditional Chinese medicine processing. The screening mesh rotates in a circular shape around the connecting shaft and can successively contact the areas of the first treatment chamber, the second treatment chamber, and the third treatment chamber inside the second fixed frame. It is blown by gas inside the first treatment chamber, wetted by liquid and scraped by a brush inside the second treatment chamber, and finally dried inside the third treatment chamber. During the cleaning process, the part of the screening mesh after being cleaned will continuously rotate into the first fixed frame. When cleaning a part of the first fixed frame, it will not cause the input of traditional Chinese medicine to stop, and the screening of traditional Chinese medicine will not stop, solving the problems raised in the above background technique.

[0006] To achieve the above object, the present invention provides the following technical solutions: A screening device for Chinese herbal medicine processing, including a first base, a first fixing frame is arranged at the upper end of the first base, a screening net is arranged inside the first fixing frame, a second fixing frame is arranged on the other side outside the first fixing frame, a first processing chamber, a second processing chamber and a third processing chamber are sequentially arranged in a surrounding manner inside the second fixing frame, a first transmission pipe is horizontally arranged inside the first processing chamber, a second transmission pipe is horizontally arranged inside the second processing chamber, and heaters are arranged at both the upper and lower ends inside the third processing chamber.

[0007] Preferably, the screening net is circular, the first fixing frame covers one-fourth of the screening net, and the second fixing frame covers three-fourths of the screening net.

[0008] Preferably, the screening net rotates counterclockwise inside the first fixing frame and the second fixing frame.

[0009] Preferably, an air tank is arranged at the upper end of the second fixing frame corresponding to the position of the first processing chamber, and a first valve is arranged between the air tank and the first transmission pipe.

[0010] Preferably, a water tank is arranged at the upper end of the second fixing frame corresponding to the position of the second processing chamber, and a second valve and a pump are arranged between the water tank and the second transmission pipe.

[0011] Preferably, a second telescopic rod with a brush at one end is horizontally arranged on one side of the second transmission pipe.

[0012] Preferably, a first telescopic rod is fixed to the upper end outside the second telescopic rod by bolts, and one end of the first telescopic rod is welded and fixed to the outer wall of the second telescopic rod.

[0013] Preferably, a vibration motor is arranged on one side of the upper end of the first base.

[0014] Preferably, there is a gap between the second fixing frame and the first fixing frame.

[0015] Preferably, a connecting ring fixed to the second fixing frame by bolts is arranged at the lower end inside the first processing chamber, and a filter screen is wrapped by glue at the lower end outside the connecting ring.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. After the screening mesh of the present invention contacts traditional Chinese medicine and has residues of traditional Chinese medicine on its surface, after being output and rotated by the servo motor corresponding to the connecting shaft, the screening mesh inside the first fixed frame can sequentially pass through the first treatment chamber, the second treatment chamber, and the third treatment chamber inside the second fixed frame. The screening mesh will sequentially receive the gas discharged from the position of the first transfer pipe to blow the residues on the surface of the screening mesh, and the screening mesh will contact the liquid discharged from the position of the second transfer pipe and receive the friction of the brush moving back and forth horizontally to further clean the screening mesh. Finally, the screening mesh will move into the third treatment chamber and be dried by the heaters at the upper and lower ends inside the third treatment chamber. The screening mesh can rotate to replace the position of contacting the medicinal materials, and gradually clean the previously contacted position of the medicinal materials through rotation, so that the entire process of screening medicinal materials can be continuously carried out for a long time, avoiding the reduction of the screening effect of medicinal materials due to the retention of medicinal materials on the surface of the screening mesh.

[0018] 2. The screening mesh of the present invention is circular, and the first fixed frame and the second fixed frame for screening traditional Chinese medicine and cleaning the screening mesh are spliced to form a circle that completely covers the screening mesh. The first fixed frame and the second fixed frame can wrap and protect the screening mesh for filtering traditional Chinese medicine and cleaning the traditional Chinese medicine. Moreover, there is a gap between the second fixed frame and the first fixed frame, so that the cleaning of the screening mesh and the filtering of traditional Chinese medicine can be carried out simultaneously, and the cleaning of the screening mesh and the filtering of traditional Chinese medicine will not affect each other and will not be affected by external pollutants.

[0025] The present invention will be further described below in conjunction with specific embodiments.

[0026] Embodiment 1: As Figure 1 and Figure 4 shown, a screening device for traditional Chinese medicine processing in this embodiment includes a first base 1. A first fixed frame 3 is arranged at the upper end of the first base 1, and the first fixed frame 3 is welded and fixed to the first base 1. A screening mesh 8 is arranged inside the first fixed frame 3. When screening traditional Chinese medicine by particle size, after the traditional Chinese medicine is put into the first fixed frame 3, it will contact the screening mesh 8 inside the first fixed frame 3. A first discharge port 4 is arranged on one side inside the first fixed frame 3. The traditional Chinese medicine that does not pass through the screening mesh 8 will be discharged from the position of the first discharge port 4. A second discharge port 29 is arranged at the lower end inside the first fixed frame 3. The traditional Chinese medicine particles that pass through the screening mesh 8 will be discharged from the position of the second discharge port 29 to the outside of the first fixed frame 3;

[0027] A feed inlet 5 is arranged at the upper end of the first fixed frame 3, and the feed inlet 5 is welded and fixed to the first fixed frame 3. The traditional Chinese medicine to be screened is transported into the first fixed frame 3 through the feed inlet 5;

[0028] In order to replace the screening mesh 8 inside the first fixed frame 3 to continuously screen traditional Chinese medicine, the screening mesh 8 is circular. The first fixed frame 3 covers one-fourth of the screening mesh 8. A second fixed frame 20 is arranged on the other side outside the first fixed frame 3. The second fixed frame 20 covers three-fourths of the screening mesh 8. The complete screening mesh 8 is completely covered by the first fixed frame 3 and the second fixed frame 20. The screening mesh 8 in the area inside the first fixed frame 3 will rotate to the inside of the second fixed frame 20 after rotation, and the screening mesh 8 can be gradually cleaned and processed inside the second fixed frame 20;

[0029] To facilitate the adjustment of the position of the screening mesh 8, the circular position of the screening mesh 8 is rotatably connected to the first fixed frame 3 through a connecting shaft 7. A servo motor 6 is provided at the upper end of the first fixed frame 3 corresponding to the connecting shaft 7, and the output shaft of the servo motor 6 is welded and fixed to the upper end of the connecting shaft 7. The outer wall of the servo motor 6 is fixedly connected to the upper end of the first fixed frame 3 by bolts. The output shaft of the servo motor 6 can drive the screening mesh 8 to rotate through the connecting shaft 7;

[0030] Among them, as Figure 2 shown, a first processing chamber 16 is provided at the front end inside the second fixed frame 20, a third processing chamber 18 is provided at the rear end inside the second fixed frame 20, and a second processing chamber 17 is provided on the other side inside the second fixed frame 20. The first processing chamber 16, the second processing chamber 17, and the third processing chamber 18 are sequentially distributed around the inside of the second fixed frame 20 in a circular manner. The screening mesh 8 rotates counterclockwise inside the first fixed frame 3 and the second fixed frame 20. The screening mesh 8 in the area of the first fixed frame 3 enters the first processing chamber 16, the second processing chamber 17, and the third processing chamber 18 one by one and then rotates into the inside of the first fixed frame 3 again;

[0031] To clean the screening mesh 8 one by one and efficiently clean the residual traditional Chinese medicine powder on the surface of the screening mesh 8, a first transmission pipe 19 is horizontally arranged inside the first processing chamber 16. Shunt pipes are sequentially arranged horizontally on the upper end of the first transmission pipe 19 facing the screening mesh 8. After the gas is transmitted into the first transmission pipe 19, the gas will be shunted through the shunt pipes and blown onto the surface of the screening mesh 8. A second transmission pipe 22 is horizontally arranged inside the second processing chamber 17. Shunt pipes are sequentially arranged horizontally on the upper end of the second transmission pipe 22 facing the screening mesh 8. After the liquid is transmitted into the second transmission pipe 22, the liquid will be shunted through the shunt pipes and flow onto the surface of the screening mesh 8. The successive contact of the gas and the liquid can improve the cleaning effect of the surface of the screening mesh 8;

[0032] In addition, to gradually transmit the liquid and the gas correspondingly, an air tank 9 is provided at the upper end of the second fixed frame 20 corresponding to the upper end of the first processing chamber 16. A first valve 10 is provided between the air tank 9 and the first transmission pipe 19, and both ends of the first valve 10 are hermetically connected to the air tank 9 and the first transmission pipe 19 respectively. After the first valve 10 is opened, the reserved gas inside the air tank 9 will be transmitted into the first transmission pipe 19 and blow the surface of the screening mesh 8;

[0033] It is worth mentioning that after the powder on the surface of the screening mesh 8 is blown off, a structure is required to collect the powder, such as Figure 3As shown in the figure, a connecting ring 21 is provided at the lower end inside the first processing chamber 16, and the connecting ring 21 is fixedly connected to the second fixing frame 20 by bolts. The connecting ring 21 can be disassembled by rotating the bolts. The lower end of the outside of the connecting ring 21 is wrapped with a filter screen 27, and the filter screen 27 is fixedly bonded to the lower end of the connecting ring 21 by glue. The blown-off debris will fall inside the filter screen 27, and the gas will directly pass through the filter screen 27 and be discharged;

[0034] It should be noted that a water tank 11 is provided at the upper end of the second fixing frame 20 corresponding to the position of the second processing chamber 17. A second valve 12 and a pump 13 are provided between the water tank 11 and the second transmission pipe 22, and the water tank 11, the second valve 12, the pump 13 and the second transmission pipe 22 are hermetically connected in sequence. After the second valve 12 is opened, the pump 13 can extract the liquid inside the water tank 11 and send the liquid into the second transmission pipe 22. The liquid sent into the second transmission pipe 22 can be discharged and wet the surface of the screening mesh 8;

[0035] Furthermore, in order to improve the cleaning effect on the wetted screening mesh 8, a second telescopic rod 15 is horizontally provided on one side of the second transmission pipe 22. One end of the second telescopic rod 15 is provided with a brush 24. The horizontal reciprocating movement of the brush 24 can be realized by the telescopic movement of the second telescopic rod 15, and the horizontal reciprocating movement of the brush 24 can rub the surface of the wetted screening mesh 8;

[0036] In addition, in order to prevent the screening mesh 8 from being continuously restricted by the brush 24 and the friction of the brush 24 during rotation, a first telescopic rod 14 is provided at the upper end of the outside of the second telescopic rod 15, and the outside of the first telescopic rod 14 is fixedly connected to the outer wall of the second fixing frame 20 by bolts. One end of the first telescopic rod 14 is welded to the outer wall of the second telescopic rod 15. The horizontal position of the second telescopic rod 15 and the brush 24 can be adjusted horizontally by the telescopic movement of the first telescopic rod 14, and the contact state between the brush 24 and the screening mesh 8 can be adjusted, reducing the friction frequency between the screening mesh 8 and the brush 24 in the rotating state;

[0037] In order to dry the wetted screening mesh 8, as Figure 5 shown, heaters 25 are provided at both the upper and lower ends inside the third processing chamber 18. The heaters 25 can be started simultaneously to heat and dry both the upper and lower ends of the screening mesh 8, so that the screening mesh 8 can be dried after cleaning, preparing for the screening mesh 8 to be sent into the first fixing frame 3 again to contact the medicinal materials;

[0038] In order to facilitate the support of the second fixing frame 20, a second base 2 is provided at the lower end of the second fixing frame 20. A vibration motor 28 is provided on one side of the upper end of the first base 1. By starting the vibration motor 28, the first fixing frame 3 and the screening mesh 8 inside the first fixing frame 3 can be shaken, which can improve the efficiency of screening drugs;

[0039] It is worth mentioning that, in order to avoid the frequent jitter of the internal structure of the second fixed frame 20 caused by the jitter of the vibration motor 28 in the screening mesh 8, and to prevent damage and loosening of the internal structure of the second fixed frame 20 after jitter, there is a gap between the second fixed frame 20 and the first fixed frame 3. Similarly, there is a gap between the first base 1 and the second base 2. Through the gap, the jitter can be avoided from affecting the internal structure of the second fixed frame 20 without hindering the rotation of the screening mesh 8;

[0040] The first fixed frame 3, the screening mesh 8, and the second fixed frame 20 are all inclined towards the first discharge port 4. Through the inclination, the traditional Chinese medicine can be discharged from the positions of the first discharge port 4 and the second discharge port 29 respectively.

[0041] In Embodiment 2, a drain pipe 23 is provided at the lower end of the second fixed frame 20 corresponding to the position of the second treatment chamber 17. After the liquid discharged from the second transfer pipe 22 contacts the screening mesh 8, the liquid will converge to the position of the second treatment chamber 17 inside the second fixed frame 20. After the drain pipe 23 is opened, the liquid retained inside the second treatment chamber 17 can be discharged.

[0042] Working principle: When using the device to screen traditional Chinese medicine of different sizes, pour the traditional Chinese medicine into the feeding port 5. The medicinal materials will fall on the upper end of the screening mesh 8. Start the vibration motor 28. The vibration generated at the position of the vibration motor 28 will cause the first base 1 and the screening mesh 8 rotatably connected to the inside of the first base 1 through the connecting shaft 7 to vibrate. The vibration of the screening mesh 8 combined with the inclination of the screening mesh 8 towards the first discharge port 4 causes the traditional Chinese medicine particles that cannot be screened by the screening mesh 8 to fall from the position of the first discharge port 4, while the traditional Chinese medicine particles that meet the caliber requirements pass through the screening mesh 8 and are finally discharged to the outside of the first fixing frame 3 from the position of the second discharge port 29. When it is necessary to clean the screening mesh 8 in the inner area of the first fixing frame 3, the output shaft of the servo motor 6 drives the screening mesh 8 to rotate clockwise through the connecting shaft 7. After the part of the screening mesh 8 in contact with the medicinal materials inside the first fixing frame 3 rotates into the second fixing frame 20, the position of the screening mesh 8 to be cleaned will enter the first treatment chamber 16. Start the first valve 10, and the gas in the gas tank 9 will pass through the first valve 10 and spray towards the screening mesh 8 from the position of the first transmission pipe 19. The gas sprayed from the position of the first transmission pipe 19 will pass through the filter mesh 27 and be discharged from the second fixing frame 20, while the debris blown off from the surface of the screening mesh 8 will remain on the detachable filter mesh 27. After the screening mesh 8 at the position of the first treatment chamber 16 continues to rotate, it will enter the position of the second treatment chamber 17 inside the second fixing frame 20. Open the second valve 12 and start the pump 13. The pump 13 pumps the water tank 11 and transmits and sprays the liquid from the position of the second transmission pipe 22 onto the surface of the screening mesh 8. Extend the first telescopic rod 14 and make the brush 24 contact the surface of the screening mesh 8. Repeat the telescoping and horizontally reciprocating adjustment of the brush 24 to make the brush 24 scrape the wet screening mesh 8. After the screening mesh 8 at the position of the first treatment chamber 16 continues to rotate, it will enter the position of the third treatment chamber 18 inside the second fixing frame 20. The heaters 25 at the upper and lower ends inside the third treatment chamber 18 will heat the wet and cleaned screening mesh 8 to dry the screening mesh 8. During the process of the screening mesh 8 rotating and being cleaned step by step, the remaining positions of the screening mesh 8 will enter the first fixing frame 3 one by one and continuously contact the traditional Chinese medicine falling from the feeding port 5 at the upper end of the first fixing frame 3.
