Description

Technical Field

[0001] This application relates to the field of screening equipment technology, and in particular to a particle screening device for the preparation of traditional Chinese medicine. Background Technology

[0002] In the preparation of traditional Chinese medicine (TCM), medicinal materials undergo processes such as pulverization, extraction, concentration, and drying, and are typically made into granules for easy administration, storage, and transportation. However, due to the complex composition of TCM raw materials, the particle size distribution of the granules is often uneven, potentially containing excessively large particles, fine powder, or clumps, which can affect the drug's dissolution rate, stability, and clinical efficacy. Therefore, particle sieving is one of the key steps in the preparation of TCM.

[0003] During the granulation of traditional Chinese medicine (TCM), some fine dust particles remain on the granules. This dust is suspended by the vibration of the vibrating screen and cannot be effectively discharged by the screen, resulting in incomplete sieving. Chinese Patent No. CN220239243U discloses a TCM granule sieving device. Through the structural design of the dust collection mechanism, it realizes the function of collecting TCM dust inside the device body and eliminating dust. However, the dust in this device is generated by the continuous collision between TCM granules and the screen, rather than being concentrated in a certain stage. It requires periodic cleaning and continuous operation of the fan, which consumes a lot of energy. Therefore, a granule sieving device for TCM preparation is proposed to solve the above problems.

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-5 This utility model provides a particle sieving device for the preparation of traditional Chinese medicine, used for sieving particles of traditional Chinese medicine during the preparation process, which has the effect of reducing energy consumption. Technical solution:

[0025] A particle sieving device for preparing traditional Chinese medicine includes a vibrating screen 1, a top plate 3 fixedly connected to the top of the housing 2 of the vibrating screen 1, a pipe 4 connected to the housing 2 fixedly connected to the upper surface of the top plate 3, a feed pipe 5 fixedly connected to the surface of the pipe 4, a fan 6, the air inlet end of the fan 6 connected to the pipe 4, and a rotating component 7 rotatably disposed inside the pipe 4, and the rotating component 7 is located at the bottom of the feed pipe 5. The rotating component 7 receives the traditional Chinese medicine particles falling from the feed pipe 5 and disperses them through rotational motion, while forcing the dust attached to the surface of the traditional Chinese medicine particles to detach.

[0026] Specifically, by setting up a feed pipe 5 to add Chinese herbal medicine granules into the pipe body 4, the blower 6 generates an upward airflow along the pipe body 4, which removes dust from the Chinese herbal medicine granules falling into the pipe body 4. By setting up a rotating part 7, the Chinese herbal medicine granules can be dispersed when it rotates. At the same time, due to the collision between the part and the Chinese herbal medicine granules, the dust attached to the surface of the Chinese herbal medicine granules is removed, which improves the effect of the airflow carrying dust out. Compared with the prior art, this embodiment only needs to turn on the blower 6 during the feeding stage, which reduces energy consumption. The vibrating screen 1 is the prior art, and its specific structure and working principle will not be described here. The blower 6 is also the prior art. The speed of the blower 6 can be adjusted by the controller to adjust the air separation as needed and improve the dust removal effect.

[0027] The top end of the tube body 4 is fixedly connected to an end cap 8. The upper surface of the end cap 8 is coaxially provided with a through hole, and the rotating part 7 is rotatably connected to the inner wall of the through hole.

[0028] The rotating component 7 includes a rotating shaft 701 rotatably connected to the inner wall of the through hole. The top of the rotating shaft 701 has a through cavity 702 extending through the bottom. Multiple evenly distributed dispersing blades 703 are fixedly connected to the surface of the rotating shaft 701 along the circumferential direction. The ends of the multiple dispersing blades 703 away from the rotating shaft 701 are fixedly connected to a fixing ring 704. The fixing ring 704 is rotatably connected to the inner wall of the tube body 4. The rotating shaft 701 drives the dispersing blades 703 to rotate. When the dispersing blades 703 rotate, they agitate the falling Chinese medicine particles, causing them to disperse. At the same time, the dispersing blades 703 collide with the Chinese medicine particles, causing the dust adhering to the Chinese medicine particles to detach. Preferably, the dispersing blades 703 are triangular to improve the contact effect with the Chinese medicine particles. Meanwhile, the dispersing blades 703 are supported by a carbon fiber modified polyurethane + PTFE / Ag composite coating, which has elastic buffering, static dissipation and surface anti-sticking functions.

[0029] A base 9 is fixedly connected to the surface of the tube body 4. A motor 10 is fixedly connected to the outside of the base 9. The output end of the motor 10 passes through the base 9 and is fixedly connected to a driving bevel gear 11. A driven bevel gear 12 is fixedly connected to the surface of the rotating shaft 701. The driving bevel gear 11 and the driven bevel gear 12 mesh, and the diameter of the driving bevel gear 11 is smaller than the diameter of the driven bevel gear 12. The output end of the motor 10 drives the driving bevel gear 11 to rotate. The driving bevel gear 11 drives the driven bevel gear 12 to rotate at a slower speed. The driven bevel gear 12 drives the rotating shaft 701 to rotate. The rotating shaft 701 drives the dispersing blade 703 to rotate. The dispersing blade 703 rotates at a slower speed to prevent the Chinese medicine granules from breaking due to high rotation.

[0030] The top end of the rotating shaft 701 is rotatably connected to a bent pipe joint 13 that communicates with the connecting cavity 702. One end of the bent pipe joint 13 is fixedly connected to a flexible hose 15, and one end of the flexible hose 15 is fixedly connected to a connecting pipe 14. The bottom end of the connecting pipe 14 is connected to the air inlet of the fan 6. By setting the bent pipe joint 13 and connecting it to the connecting pipe 14, interference with the rotation of the rotating shaft 701 is avoided. By setting the flexible hose 15, the vibration transmitted by the vibrating screen 1 during operation is reduced.

[0031] It also includes a dust collection box 16, with a filter screen 17 fixedly connected to the inner wall of the dust collection box 16. An installation port is opened on the surface of the dust collection box 16 and is located below the filter screen 17. The fan 6 is fixedly connected to the inner wall of the installation port. A box cover 18 is detachably connected to the top of the dust collection box 16. The bottom end of the connecting pipe 14 is fixedly connected to the box cover 18 and is connected to the dust collection box 16.

[0032] The inner wall of the box body 2 is fixedly connected to a first screen 19 and a second screen 20, respectively. The screen aperture of the first screen 19 is larger than that of the second screen 20. The side of the box body 2 is provided with a first discharge port and a second discharge port corresponding to the first screen 19 and the second screen 20, respectively. The inner wall of the first discharge port is fixedly connected to a first discharge guide plate 21, and the inner wall of the second discharge port is fixedly connected to a second discharge guide plate 22. A discharge port is provided at the bottom of one side of the box body 2, and a baffle 23 is detachably connected inside the discharge port. Larger Chinese medicine particles are screened out by the first screen 19, and smaller Chinese medicine particles are screened out by the second screen 20. The connection between the baffle 23 and the box body 2 is preferably a snap-fit ​​connection.

[0033] Working Principle: When using this granule sieving device for traditional Chinese medicine preparation, the user first adds the granules of traditional Chinese medicine into the tube body 4 through the feed pipe 5. Simultaneously, the blower 6, motor 10, and vibrating screen 1 are started. The blower 6 generates an upward airflow along the tube body 4, removing dust from the granules falling into the tube body 4. During this process, the output end of the motor 10 drives the driving bevel gear 11 to rotate. The driving bevel gear 11 drives the driven bevel gear 12 to rotate at a slower speed. The driven bevel gear 12 drives the rotating shaft 701 to rotate, which in turn drives the dispersing blades 703 to rotate, dispersing the granules at a slower speed. When the blades 703 rotate, they agitate the falling Chinese herbal medicine granules, dispersing them. The dispersing blades 703 also collide with the Chinese herbal medicine granules, causing the dust attached to the granules to fall off. At the same time, it prevents the Chinese herbal medicine granules from breaking due to high rotation. After feeding is completed, the blower 6 and motor 10 can be turned off. The Chinese herbal medicine granules that have been cleaned of dust fall into the vibrating screen 1. Larger particles are removed by the first screen 19, and smaller particles are removed by the second screen 20. The Chinese herbal medicine granules that meet the particle size requirements are selected. Compared with the prior art, this Chinese herbal medicine preparation particle screening device only needs to turn on the blower 6 during the feeding stage, which reduces energy consumption.
