Description
Technical Field
[0001] This utility model relates to the field of traditional Chinese medicine decoction piece processing technology, and in particular to a traditional Chinese medicine decoction piece screening device with efficient impurity removal function. Background Technology
[0002] Screening of Chinese medicinal herbs is a crucial step in the purification process of Chinese medicinal herb production. It aims to remove impurities (such as sand, mud, and debris) and non-medicinal parts (such as residual stems, broken leaves, and insect-damaged or moldy parts) from the herbs and herbs through physical separation methods, or to classify them by size and shape. This improves the purity, uniformity, and safety and efficacy of the herbs for clinical use. Traditional screening methods often use bamboo sieves, wire sieves, and silk sieves, separating herbs and impurities based on volume differences. Modern methods have developed vibrating sieve machines, electric sieves, and intelligent sorting equipment, further improving screening efficiency and accuracy, ensuring that the herbs meet medicinal purity standards and clinical dispensing requirements.
[0003] A traditional Chinese medicine (TCM) decoction piece screening mechanism is disclosed in utility model application number 202020476515.X. The mechanism uses the size of the circular holes in different areas of the screening cylinder to sort the TCM decoction pieces into a collection box according to their size, making screening convenient and effective. A removal box with an inclined filter screen is installed between the feed hopper and the screening cylinder. Small particulate impurities in the TCM decoction pieces can fall through the filter screen into the collection box. After removal, the TCM decoction pieces enter the screening cylinder from the feed inlet, ensuring that the screened TCM decoction pieces are free of small particulate impurities. The collection box and the discharge pipe are slidably connected, allowing for easy separation when the collection box is full, facilitating the emptying of impurities. A baffle screen on the discharge channel prevents the screened TCM decoction pieces from falling out. One side of the collection box with the handle is transparent, allowing observation of the TCM decoction piece collection process. In the aforementioned screening mechanism for Chinese medicinal herbs, the top of the screening cylinder is directly exposed, making it easy for external dust to enter the screening cylinder through the holes and contaminate the Chinese medicinal herbs. When using an inclined filter screen to remove impurities from the Chinese medicinal herbs in the aforementioned screening mechanism, small pieces of Chinese medicinal herbs are easily discharged from the impurity removal pipe along with the impurities. The lack of further screening between small pieces of Chinese medicinal herbs and impurities easily leads to waste of Chinese medicinal herbs. Therefore, this utility model proposes a screening device for Chinese medicinal herbs with a highly efficient impurity removal function to solve the problems existing in the prior art. Utility Model Content
[0004] To address the aforementioned problems, the purpose of this utility model is to propose a screening device for Chinese herbal medicine slices with efficient impurity removal function. This device effectively limits and guides the screened Chinese herbal medicine slices in a fully enclosed environment by rotating the screening cylinder within a closed screening chamber. This allows slices of different sizes to be discharged from different discharge ports, solving the problem that the top of the screening cylinder is directly exposed, making it easy for external dust to enter the screening cylinder through the holes and contaminate the Chinese herbal medicine slices. A vacuum cleaner, in conjunction with a filter screen, removes impurities from the slices entering the feeding box and transfers them to the impurity collection box, achieving efficient and automated impurity removal. This also solves the problem that when the filter screen is installed at an angle, small pieces of Chinese herbal medicine slices are easily discharged from the impurity discharge pipe along with the impurities.
[0005] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: A screening device for traditional Chinese medicine decoction pieces with efficient impurity removal function, including a screening table, a support, a feeding box, a closed screening mechanism, an impurity adsorption mechanism, and a separating receiving mechanism. A support is fixedly provided on one side of the screening table, and a feeding box is fixedly provided on one side of the support. The closed screening mechanism includes a receiving seat, a closed screening cylinder, a rotating screening cylinder, screening holes, a first motor, a discharge port, and a limiting and stabilizing mechanism.

A discharge port is arranged and fixed between the closed screening cylinder and the receiving seat. A limiting and stabilizing mechanism is provided inside the closed screening cylinder, and an impurity adsorption mechanism is provided on one side of the screening table.
[0006] A further improvement is that multiple sets of screening holes are formed around the perimeter, and the screening holes gradually expand from one side to the other.
[0007] A further improvement is that the limiting and stabilizing mechanism includes a hollow partition plate, a limiting ring, and an outer partition plate. Hollow partition plates are arranged and fixed inside the rotating screening cylinder, a limiting ring is fixed on one side inside the closed screening cylinder, and outer partition plates are arranged and fixed inside the closed screening cylinder.
[0008] A further improvement is that the inner side of the limiting ring is in contact with the outer wall of the rotating screening cylinder, and the inner side of the outer partition plate is in contact with the outer wall of the rotating screening cylinder.
[0009] A further improvement is that the impurity adsorption mechanism includes an impurity collection box, a vacuum cleaner, a corrugated pipe, and a filter screen. The collection box is fixedly installed on one side of the screening table, and the vacuum cleaner is fixedly installed on one side of the collection box. The vacuum cleaner is connected to the upper side of the feeding box via a corrugated pipe, and the upper side of the feeding box is fixedly installed with a filter screen.
[0010] A further improvement is that a second motor is fixedly installed on the lower side of the feeding box, and a feeding auger is rotatably installed inside the lower part of the feeding box. The output end of the second motor is connected to the feeding auger for driving. A feeding pipe is provided between the feeding box and the closed screening cylinder.
[0011] A further improvement is that: a receiving partition plate is fixedly arranged inside the receiving seat, the receiving seat has an opening at the front, a receiving box is slidably arranged inside the receiving seat, and a handle is fixedly provided at the front of the receiving box.
[0012] The beneficial effects of this utility model are as follows: This utility model achieves effective limiting and guiding of the screened Chinese herbal medicine slices in a fully enclosed environment by rotating the screening cylinder within the closed screening cylinder, so that slices of different sizes are discharged from different feed ports. This solves the problem that the top of the screening cylinder is directly exposed, and external dust can easily enter the screening cylinder through the holes and contaminate the Chinese herbal medicine slices. By using a vacuum cleaner in conjunction with a filter screen to remove impurities from the slices entering the feed box to the impurity collection box, efficient and automated impurity removal is achieved. This solves the problem that when the filter screen is installed at an angle to remove impurities from the Chinese herbal medicine slices, small pieces of Chinese herbal medicine slices are easily discharged from the impurity discharge pipe along with the impurities.

[0015] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.
[0016] according to Figure 1 , Figure 2 , Figure 3As shown, this embodiment provides a screening device for Chinese herbal medicine slices with efficient impurity removal function, including a screening table 1, a support 2, a feeding box 3, a closed screening mechanism, an impurity adsorption mechanism, and a separating receiving mechanism. The support 2 is fixedly installed on one side of the screening table 1, and the feeding box 3 is fixedly installed on one side of the support 2. The closed screening mechanism includes a receiving seat 4, a closed screening cylinder 5, a rotating screening cylinder 6, screening holes 7, a first motor 8, a discharge port 9, and a limiting and stabilizing mechanism. The receiving seat 4 is fixedly installed in the middle of the screening table 1, and the closed screening cylinder 5 is fixedly installed at an incline on the receiving seat 4. The rotating screening cylinder 6 is rotatably installed inside the closed screening cylinder 5. Screening holes 7 are arranged around the rotating screening cylinder 6. Multiple sets of screening holes 7 are arranged around the rotating screening cylinder 6, and the screening holes 7 gradually enlarge from one side to the other side. A first motor 8 is fixedly installed on the other side of the screening table 1. The output end of the first motor 8 is connected to the rotating screening cylinder 6. A discharge port 9 is fixedly arranged between the closed screening cylinder 5 and the receiving seat 4. When screening Chinese herbal medicine pieces, the first motor 8 drives the rotating screening cylinder 6 to rotate inside the closed screening cylinder 5. The centrifugal force generated by the rotating screening cylinder 6 cooperates with the screening holes 7 to achieve separation and screening according to the different sizes of Chinese herbal medicine pieces. The closed screening cylinder 5 is sleeved on the outside of the rotating screening cylinder 6 to effectively guide the screened Chinese herbal medicine pieces to fall from the corresponding discharge port 9. This solves the problem that the top of the screening cylinder is directly exposed, and external dust can easily enter the screening cylinder through the holes and contaminate the Chinese herbal medicine pieces. A limiting and stabilizing mechanism is provided inside the closed screening cylinder 5, and an impurity adsorption mechanism is provided on one side of the screening table 1.
[0017] The limiting and stabilizing mechanism includes a hollow partition plate 10, a limiting retaining ring 11, and an outer partition plate 12. The hollow partition plate 10 is fixedly arranged inside the rotating screening cylinder 6, and the limiting retaining ring 11 is fixedly arranged on one side inside the closed screening cylinder 5. The outer partition plate 12 is also fixedly arranged inside the closed screening cylinder 5. The inner side of the limiting retaining ring 11 is in contact with the outer wall of the rotating screening cylinder 6, and the inner side of the outer partition plate 12 is in contact with the outer wall of the rotating screening cylinder 6. When the rotating screening cylinder 6 rotates inside the closed screening cylinder 5, the limiting retaining ring 11 and the outer partition plate 12 provide limiting support for the rotating screening cylinder 6, ensuring its stability during rotation and preventing mixing of different sized Chinese medicinal herbs after screening.
[0018] The impurity adsorption mechanism includes an impurity collection box 13, a vacuum cleaner 14, a corrugated pipe 15, and a filter screen 16. A collection box is fixedly installed on one side of the screening table 1, and a vacuum cleaner 14 is fixedly installed on one side of the collection box. The vacuum cleaner 14 is connected to a corrugated pipe 15 on one side of the feeding box 3, and a filter screen 16 is fixedly installed on one side of the feeding box 3. When it is necessary to clean the dust and impurities in the Chinese herbal medicine slices, the vacuum cleaner 14 starts to vacuum and suck out the impurities and dust in the Chinese herbal medicine slices that have entered the feeding box 3. At the same time, the filter screen 16 is used to filter the Chinese herbal medicine slices. The impurities are sucked into the impurity collection box 13 through the corrugated pipe 15, thereby achieving efficient filtration of impurities and dust in the Chinese herbal medicine slices.
[0019] A second motor 17 is fixedly installed on the lower side of the feeding box 3. A feeding auger 18 is rotatably installed inside the lower part of the feeding box 3. The output end of the second motor 17 is connected to the feeding auger 18. A feeding pipe 19 is provided between the feeding box 3 and the closed screening cylinder 5. When feeding, the second motor 17 drives the feeding auger 18 to rotate, pushing the Chinese herbal medicine pieces through the feeding pipe 19 into the rotating screening cylinder 6 to achieve continuous feeding.
[0020] The receiving seat 4 is equipped with a receiving partition plate 20. The receiving seat 4 has an opening at the front and a receiving box 21 is slidably arranged inside the receiving seat 4. The receiving box 21 is equipped with a handle 22 at the front. The screened Chinese herbal medicine pieces fall into the corresponding receiving box 21 after falling out through the discharge port 9. After screening is completed, the handle 22 is pulled to pull the receiving box 21 out of the receiving seat 4 for easy collection of Chinese herbal medicine pieces.
[0021] This highly efficient herbal medicine screening equipment first feeds the herbal medicine pieces into the feeding hopper. A second motor drives the feeding auger, continuously feeding the material into a rotating screening cylinder within a closed system. Simultaneously, a vacuum cleaner is activated during the feeding phase, removing dust and impurities from the herbs through a corrugated pipe and filter screen to a collection box. The first motor then drives the rotating screening cylinder at high speed. Centrifugal force forces the herbal medicine pieces through progressively enlarging screening holes during rotation, achieving grading. Pieces of different particle sizes fall into individual collection boxes at the receiving station through corresponding discharge ports. The enclosed design effectively prevents external contamination. After screening, finished products of various sizes can be easily removed via handles on the front of the collection boxes. The entire process integrates dynamic screening, multi-stage dust removal, and automatic packaging, balancing high efficiency and cleanliness control.
