[0002] During the harvesting, drying, transportation, and storage of Chinese medicinal herbs, a large amount of non-medicinal impurities such as mud, dust, hair, weeds, and fiber ropes will be mixed in. These impurities not only have no therapeutic effect, but also directly contaminate the medicine. In order to remove impurities, reduce pollution, ensure accurate dosage, improve efficacy, facilitate storage, and ultimately ensure that every piece of Chinese medicinal herb produced is pure, safe, and effective, meeting the high standards of pharmaceuticals, it will be subjected to wind separation and dust removal treatment during production.

[0003] Currently, when performing air separation dust removal on Chinese herbal medicine slices, the method of combining top-down falling with air blowing is mostly used. During this process, the material accumulates together, which obstructs the dust and results in insufficient dust removal.

[0004] To address the aforementioned issues, this application proposes a circulating air separation dust removal device for traditional Chinese medicine decoction pieces. Utility Model Content

[0005] The purpose of this invention is to provide a circulating air separation and dust removal device for traditional Chinese medicine decoction pieces, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a circulating air separation dust removal device for Chinese herbal medicine slices, including an air separation dust removal machine installed with the left side higher than the right side and a base at its bottom. A circulating fan is installed on the upper left end of the base, and an inlet and a outlet are installed on the upper left end and the lower right end of the air separation dust removal machine, respectively.

[0008] The double-sided dust removal mechanism is located inside the air classifier and is driven to rotate by a rotary motor. It has an inner ring frame and an outer ring frame, and a material conveying interlayer is formed between the inner ring frame and the outer ring frame. The interior of the inner ring frame and the outer ring frame is an annular cavity for transmitting air.

[0009] The flipping mechanism, located inside the interlayer, consists of circumferentially evenly arranged partitions, with adjacent lateral partitions staggered along the axial cross section.

[0010] Preferably, the left end of the air classifier dust collector is equipped with a bearing seat, and a rotating shaft connected to a rotary motor is rotatably mounted inside the shaft. The right end of the rotating shaft is equipped with a connecting rod connected to the inner ring frame and the outer ring frame.

[0011] Preferably, a fixed frame is installed inside the left end of the air classifier dust collector, and an outer support frame and an inner support frame are fixed inside the fixed frame to clamp the integral structure extending from the left end of the inner ring frame to form a close fit, seal and support.

[0012] Preferably, an annular plate extends inward from the edge of the fixing frame, forming a tight seal and support with the integral structure extending from the left end of the outer ring frame, and the upper end of the annular plate is fixedly connected to the feed port.

[0013] Preferably, the inner and outer rings of the inner ring frame are an outer mesh cylinder and an inner cylinder, respectively, and the inner and outer rings of the outer ring frame are an inner mesh cylinder and an outer cylinder, respectively. An annular space is formed between the inner and outer rings of the inner and outer ring frames, which is interconnected with the air extraction ring frame that extends out of the structure on the left end.

[0014] Preferably, the left side of the suction ring frame is a ventilation ring frame, and the suction ring frame and the ventilation ring frame are interconnected.

[0015] Preferably, the left end of the ventilation ring frame is equipped with a ventilation pipe connected to the circulating fan.

[0016] This utility model has the following beneficial effects:

[0017] 1. By using a sandwich-type rotary conveyor between the inner and outer ring frames, and utilizing the annular suction chambers inside the inner and outer ring frames, double-sided blowing dust removal can be formed during material conveying, which helps to improve the dust removal efficiency of the material.

[0018] 2. The material is conveyed by a rotating sandwich between the inner and outer ring frames. The staggered distribution of the partitions causes the material to fall intermittently onto the adjacent partitions during rotation, thereby achieving material turning and moving the dust blocked inside to the outside, thus achieving a thorough dust removal effect.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] A circulating air separation dust removal device for Chinese herbal medicine slices is set up to assist in the air separation dust removal of Chinese herbal medicine slices. The inner ring frame 61 and the outer ring frame 62 are combined to form a ring-shaped material conveying channel. The built-in partition 63 is used to turn the material during rotation, thereby forming a dust removal effect of double-sided air separation and material turning, and improving the fullness of air separation dust removal.

[0032] In some embodiments, the specific structure of the circulating air separation dust removal device for traditional Chinese medicine decoction pieces is as follows: Figure 1As shown in Figure 2, the dust collector includes an air classifier 1 and a base 2 at its bottom. The air classifier 1 is installed with the left side higher than the right side. There is an inlet 4 and an outlet 5 at the top of one end and the bottom of the other end of the air classifier 1, respectively. There is a circulating fan 3 at the top of one end of the base 2.

[0033] The double-sided dust removal mechanism has an inner ring frame 61 and an outer ring frame 62, which form an annular interlayer for material conveying. The interior of the inner ring frame 61 and the outer ring frame 62 are connected to the interlayer space and are also connected to the circulating fan 3 through pipelines.

[0034] The material turning mechanism consists of partitions 63 within the interlayer space. Each set of partitions 63 is arranged at equal intervals around the circumference, with adjacent sets staggered by 10 degrees around the circumference. There are at least 5 sets.

[0035] Among them, the double-sided dust removal mechanism uses a rotary motor as the power source to rotate along the axis. The two ends of the interlayer space are open structures, with the left end opening connected to the feed port 4 and the right end opening connected to the discharge port 5.

[0036] like Figure 2 As shown in Figure 3, the left end area inside the air classifier dust collector 1 is a fixed frame 12. The right side of the fixed frame 12 has an outer support frame 121 and an inner support frame 122, which fit into the inner and outer sides of the left end protruding structure of the inner ring frame 61 to form a sealing and support effect.

[0037] Among them, the edge of the fixed frame 12 extends inward with an annular frame body, the upper end of which is used to connect to the feed port 4. The outer side of the annular frame body is attached to the inner side of the left end of the outer ring frame 62 to form a sealing and support effect.

[0038] It is understandable that the inlet 4 is connected to the annular cavity in the outer ring area of ​​the fixed frame 12, which is connected to the interlayer space and is used to input materials into the interlayer space.

[0039] like Figure 2 As shown in Figure 3, a bearing seat 11 extends to the right from the left end of the air classifier dust collector 1. A rotating shaft 111 extending from the rotating motor is rotatably installed inside the bearing seat 11. A connecting rod 64 is fixedly installed on the outer side of the right end of the rotating shaft 111.

[0040] Among them, the connecting rods 64 are evenly arranged around the circumference and are fixedly connected to the inner ring frame 61 and the outer ring frame 62, which are used to drive the double-sided dust removal mechanism to rotate.

[0041] like Figure 2 As shown in Figure 5, the inner ring frame 61 and the outer ring frame 62 extend out of the structure to form an annular space, which contains a vacuum ring frame 65. The vacuum ring frame 65 is connected to the internal space of the inner ring frame 61 and the outer ring frame 62.

[0042] Among them, the left side of the extraction ring frame 65 is the ventilation ring frame 651, and the left end of the ventilation ring frame 651 is equipped with a ventilation pipe 652 for connecting to the circulating fan 3.

[0043] Furthermore, the inner ring frame 61 has an inner cylinder 611 and an outer mesh cylinder 612, and the outer ring frame 62 has an inner mesh cylinder 622 and an outer cylinder 621. The annular space between the inner cylinder 611 and the outer mesh cylinder 612 and the annular space between the outer cylinder 621 and the inner mesh cylinder 622 are both connected to the suction ring frame 65. The closed plates at the left ends of the inner ring frame 61 and the outer ring frame 62 have through holes.

[0044] The specific usage methods of the circulating air separation dust removal device for Chinese herbal medicine slices, as disclosed in some publications, are as follows:

[0045] S1. The material is loaded from the feed port 4. The material enters the annular space of the inner outer ring area of ​​the fixed frame 12. Under the guidance formed by the inclined installation of the air classifier dust collector 1, the material enters the interlayer between the inner ring frame 61 and the outer ring frame 62 to start air classification dust removal.

[0046] S2, the bearing seat 11 is driven by a rotary motor, which drives the inner ring frame 61 and the outer ring frame 62 to rotate via the connecting rod 64. Under the guidance, the material falls from left to right to the top of the partition plate 63 to form a flipping process.

[0047] S3. During the rotation of the inner ring frame 61 and the outer ring frame 62, the suction ring frame 65 is always connected to the internal space of the inner ring frame 61 and the outer ring frame 62 through the through hole opened in the closed plate at the left end of the inner ring frame 61 and the outer ring frame 62, thereby transmitting the suction force generated by the circulating fan 3 to the interior of the inner ring frame 61 and the outer ring frame 62.

[0048] S4. By utilizing the inner cylinder 611 of the outer ring of the inner ring frame 61 and the outer cylinder 621 of the inner ring of the outer ring frame 62, the suction air force enters the interlayer space, forming a bidirectional and continuous air separation and dust removal treatment for the material.

[0049] S5. The material is finally discharged outward through the right end opening of the interlayer space into the discharge port 5.
