Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine pill production technology, specifically a sealed drying device for traditional Chinese medicine pills. Background Technology

[0002] Pills are spherical or near-spherical preparations made from fine powders or extracts of medicinal materials with suitable binding excipients. They are classified according to excipients: water pills, honey pills, water-honey pills, paste pills, wax pills, etc. For ease of use, Chinese medicine is made into pills, which are easy to carry and store. In the process of manufacturing Chinese medicine pills, the pills need to be dried in order to ensure the drug content and its stability.

[0003] Existing equipment often uses static electric heating to dry Chinese medicine pills. In order to improve the drying efficiency of Chinese medicine pills, the static Chinese medicine pills are often laid in multiple layers. This causes moisture to accumulate inside the lower layers of Chinese medicine pills, resulting in uneven drying between the lower and upper layers, which in turn affects the shelf life of the Chinese medicine pills. Therefore, we need to propose a sealed drying device specifically for Chinese medicine pills. Utility Model Content

[0004] The purpose of this invention is to provide a sealed drying device specifically for traditional Chinese medicine pills. By setting a flow channel inside the sealed chamber, the drying time of the traditional Chinese medicine pills is increased, while ensuring that the pills are heated and dried evenly. At the same time, the generated hot and humid air can flow upward to form a sealed drying space inside the chamber, thereby improving the drying efficiency of traditional Chinese medicine pills and realizing continuous drying processing of traditional Chinese medicine pills, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealed drying device specifically for traditional Chinese medicine pills, comprising:

[0006] The box body, and multiple sets of drainage mechanisms and multiple sets of guide plates installed in the inner cavity of the box body.

[0009] Preferably, multiple sets of guide plates are arranged in an alternating staggered manner, a discharge hopper is installed at the lower end of the other side of the box, a feed hopper is installed at one end of the upper surface of the box, and slag storage mechanisms are installed on both sides of the box.

[0010] Preferably, the slag storage mechanism includes a side cover, one side of which has multiple sets of through holes, and both sides of the box body have slag discharge troughs that communicate with the through holes. The slag discharge troughs are located at the discharge end of the diversion plate. A drawer is inserted into the side of the side cover adjacent to the through holes, and an inclined plate is fixedly connected to the side of the side cover cavity above the drawer.

[0011] Preferably, the blowing drying mechanism includes an air inlet pipe fixedly connected to one side of the housing. A dustproof mesh cover, a filter, a fan, and multiple sets of heating rods are sequentially installed inside the air inlet pipe from the air inlet end to the air outlet end.

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a sealed drying device for traditional Chinese medicine pills, including a box 1, a blowing drying mechanism 6 disposed on one side of the box 1, multiple sets of diversion mechanisms 9 and multiple sets of guide plates 10 installed in the inner cavity of the box 1, the multiple sets of guide plates 10 are all disposed below the bottommost diversion mechanism 9, and a hot air circulation channel for drying traditional Chinese medicine pills is formed between the multiple sets of diversion mechanisms 9 and the topmost guide plate 10;

[0023] The inner cavity of the box 1 is equipped with a cooling mechanism 7 above the bottom guide plate 10, which is connected to the blowing drying mechanism 6. The blowing drying mechanism 6 dries the Chinese medicine pills with hot air while drawing in some air to cool the dried Chinese medicine pills.

[0024] In this embodiment, multiple sets of drainage mechanisms 9 are arranged alternately and staggered, and each set of drainage mechanisms 9 includes a drainage plate 91 and a filter plate 92. The filter plate 92 is fixedly connected to one end of the upper surface of the drainage plate 91. Multiple sets of filter holes 93 are opened on the filter plate 92. The included angle between the filter plate 92 and the drainage plate 91 is an acute angle.

[0025] Specifically, the multiple sets of drainage mechanisms 9 are alternately staggered, which can guide the Chinese medicine pills to move slowly in an S-shaped path within the box 1, greatly extending the contact time between the pills and the hot air, avoiding insufficient drying in some areas, and improving the uniformity of drying.

[0026] Secondly, the filter holes 93 on the filter plate 92 can filter the debris and dust generated during the movement of the Chinese medicine pills, preventing the accumulation of impurities from affecting the internal environment of the device and the quality of the pills. The acute angle structure (with an included angle of 20-30°) can also help the hot air to flow more smoothly in the hot air circulation channel, ensuring the efficiency of hot air circulation.

[0027] Furthermore, multiple sets of guide plates 10 are arranged alternately and staggeredly, a discharge hopper 3 is installed at the lower end of the other side of the box body 1, a feed hopper 2 is installed at one end of the upper surface of the box body 1, and slag storage mechanisms 8 are installed on both sides of the box body 1.

[0028] Specifically, multiple sets of guide plates 10 are alternately staggered to form a continuous material conveying path with the upper diversion mechanism 9, ensuring that the dried Chinese medicine pills can move downwards smoothly and orderly, avoiding jamming and accumulation, and improving the stability of material conveying. The setting of feed hopper 2 and discharge hopper 3 respectively realizes convenient feeding of pills and centralized discharge after drying, simplifying the operation process and improving the overall work efficiency.

[0029] Preferably, the slag storage mechanism 8 includes a side cover 81, with multiple sets of through holes 82 on one side of the side cover 81. Both sides of the box body 1 are provided with slag discharge troughs 11 that communicate with the through holes 82. The slag discharge troughs 11 are located at the discharge end of the diversion plate 91. A drawer 84 is inserted into the side of the side cover 81 adjacent to the through holes 82. An inclined plate 83 is fixedly connected to the side of the inner cavity of the side cover 81 above the drawer 84. The slag storage mechanism 8 can collect impurities filtered out by the filter screen plate 92, preventing impurities from accumulating in the box body 1 and contaminating the pellets or blocking the hot air passage, thus ensuring the long-term stable operation of the device.

[0030] Specifically, the through hole 82 is connected to the slag discharge trough 11 of the box body 1, which can accurately receive the impurities discharged from the discharge end of the guide plate 91 and prevent the impurities from scattering. The drawer 84 is convenient for staff to regularly pull out and clean the impurities without disassembling the device, reducing the difficulty of maintenance. The inclined plate 83 can guide the impurities to fall smoothly into the drawer 84, preventing the impurities from accumulating in the inner cavity of the side cover 81 and blocking the through hole 82, thereby indirectly improving the quality of the dried Chinese medicine pills.

[0031] In a further preferred embodiment, the blowing drying mechanism 6 includes an air inlet pipe 61 fixedly connected to one side of the housing 1. A dustproof mesh cover 62, a filter 64 (existing technology, not described in detail), a fan 65 and multiple sets of heating rods 67 are installed sequentially from the air inlet end to the air outlet end inside the air inlet pipe 61. Both sides of the dustproof mesh cover 62 are threaded with fixing bolts 63 that are bolted to the air inlet pipe 61. Both sides of the inner cavity of the air inlet pipe 61 are fixedly connected with limiting beams 611 that restrict the installation position of the filter 64. The inner cavity of the air inlet pipe 61 is fixedly connected with a partition 66 that isolates the multiple sets of heating rods 67.

[0032] Specifically, the dustproof mesh cover 62 and the filter 64 can dually filter dust, particulate matter and other impurities in the air, preventing impurities from entering the box 1 with the hot air and contaminating the Chinese medicine pills, thus ensuring the hygiene and safety of the Chinese medicine pills. The dustproof mesh cover 62 is connected by fixing bolts 63, which makes it easy to disassemble, clean or replace, reducing maintenance costs. The limiting beam 611 can accurately fix the position of the filter 64 to prevent it from shifting when the fan 65 is working, ensuring stable filtration effect. The partition 66 increases the contact time between the air and the heating rod 67, thereby ensuring the heating effect of the heating rod 67 on the air.

[0033] Furthermore, the cooling mechanism 7 includes a hollow plate 71, and connecting pipes 72 penetrating the housing 1 are installed on both sides of the hollow plate 71. An air collecting hood 73 is provided at the opposite end of each of the two sets of connecting pipes 72. Side air holes 613 communicating with the air collecting hood 73 are opened on both sides of the air inlet pipe 61. A guide plate 612 located at one end of the side air hole 613 is fixedly connected to both sides of the inner cavity of the air inlet pipe 61.

[0034] The air guide plate 612 can guide the air that has not been heated by the heating rod 67 to enter the side air hole 613 precisely, so that the cooling air at room temperature is blown evenly to the dried pills through the hollow plate 71. This can reduce the temperature of the pills and prevent the high-temperature pills from deteriorating or sticking due to excessive temperature after being discharged directly. At the same time, it reduces the cooling waiting time before subsequent packaging, improves the overall production efficiency, and the cooling air is taken from the air inlet pipe 61, so there is no need to set up an additional independent air source.

[0035] In addition, a bracket 4 and a vibration motor 5 are fixedly connected to the lower surface of the housing 1, and multiple sets of flow guide plates 91 are arranged parallel to the uppermost flow guide plate, and multiple sets of filter screen plates 92 are arranged parallel to the material guide plate 10 above the hollow plate 71.

[0036] When the vibration motor 5 is working, it can drive the box 1 to vibrate slightly. On the one hand, it helps the Chinese medicine pills on the diversion plate 91 and the guide plate 10 to move, and prevents the Chinese medicine pills from adhering to the filter screen plate 92 due to stickiness or static electricity, thus ensuring smooth material conveying. On the other hand, it can make the pills turn slightly on the plate surface, reducing the contact area between the Chinese medicine pills and the plate surface, so that the hot air can contact the pill surface more fully and improve the drying uniformity.

[0037] When in use, the Chinese medicine pills to be dried are put into the box 1 through the feed hopper 2. The Chinese medicine pills first fall on the top drainage mechanism 9. Under the action of the vibration motor 5 driving the box 1 to vibrate slightly, the Chinese medicine pills move slowly along the alternating filter screen 92. At the same time, the filter screen 92 filters the residue, dust and impurities in the Chinese medicine pills through the filter holes 93. The pills are then collected in the drawer 84 inside the side cover 81 through the drainage plate 91, the slag discharge trough 11 and the through hole 82.

[0038] During the movement of the pills, the blowing drying mechanism 6 starts to work. The fan 65 draws outside air into the air inlet pipe 61. The air first passes through the dustproof mesh cover 62 to filter out large particles of impurities, and then passes through the filter 64 to filter out fine dust. After being heated by the heating rod 67, the hot air enters the box 1 and flows along the hot air circulation channel formed by the diversion mechanism 9 and the guide plate 10. It comes into full contact with the moving Chinese medicine pills, absorbs the moisture in the pills, and dries them. The alternating diversion mechanism 9 extends the contact time between the Chinese medicine pills and the hot air, ensuring the uniformity of drying.

[0039] After the Chinese medicine pills are dried, they are moved to the lower guide plate 10. Part of the room temperature air in the air inlet pipe 61 is guided by the air guide plate 612 and enters the air collection hood 73 through the side air hole 613. Then it is transported to the hollow plate 71 through the connecting pipe 72. The room temperature air is blown evenly onto the dried pills through the air holes (not shown in the figure) on the lower surface of the hollow plate 71 to cool down the Chinese medicine pills so as to facilitate the storage of the Chinese medicine pills.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
