Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of drying and impurity removal devices for traditional Chinese medicine decoction pieces, specifically an integrated drying and impurity removal device for traditional Chinese medicine decoction pieces. Background Technology
[0002] In the production and processing of Chinese medicinal herbs, drying and impurity removal are two crucial steps. The purpose of drying is to remove excess moisture from the medicinal herbs to ensure their stable quality and facilitate storage and transportation; impurity removal is to remove impurities mixed in with the herbs, thereby improving their purity and quality.
[0003] Many existing drying methods for Chinese medicinal herbs tend to cause them to pile up. This piling not only reduces the surface area in contact with hot air but also hinders the uniformity of heat transfer, making it difficult for the herbs to be fully dried. This often results in a lengthy drying process, severely impacting the quality of the herbs. Furthermore, the drying chamber typically needs to be opened during loading and unloading, leading to significant heat loss. To maintain the required drying temperature, the device consumes more energy to replenish heat, increasing production costs. To address these shortcomings, we propose an integrated drying and impurity removal device for Chinese medicinal herbs to solve these problems. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0027] This utility model discloses an integrated device for drying and removing impurities from Chinese herbal medicine slices.
[0028] According to the appendix Figure 1-9 As shown, the system includes a drying chamber body 1, with multiple drawer bodies 2 slidably connected inside the drying chamber body 1. The drawer bodies 2 are equidistantly distributed along the height of the drying chamber body 1. A waste collection assembly 3 is installed at the bottom of each drawer body 2, and a baking assembly 4 is installed at the top of each drawer body 2. The baking assembly 4 is fixedly installed inside the drying chamber body 1. The waste collection assembly 3 collects the sieved waste, and the baking assembly 4 bakes the material. During use, the dried medicinal materials are first dispersed and laid flat inside the multiple material frames 201. Then, the multiple material frames 201 containing the materials are pushed into the drying chamber body 1, so that… The magnets on the outer wall of the material frame 201 and the magnets on the inner wall of the support frame 5 are magnetically attracted. Then, by activating the drive component 6, the drive component 6 is activated, which drives multiple sets of material frames 201 to slide back and forth inside the drying chamber body 1. This disperses the material inside the multiple sets of material frames 201, allowing each piece of Chinese herbal medicine to have a larger surface area exposed to the hot air in the drying chamber. This increases the contact area and contact opportunities with the hot air, making the heat transfer more thorough and uniform. It avoids the situation where the pieces of medicine are stacked together, making it difficult for them to be heated and dried inside. This greatly improves the drying speed and efficiency and shortens the drying time.
[0029] The drying oven body 1 has multiple sets of support frames 5 inside, which support the drawer body 2 respectively. A drive component 6 is provided on one side of the drying oven body 1. The drive component 6 drives the multiple sets of support frames 5 to slide inside the drying oven body 1. During the drying process, the material frame 201 slides back and forth, so that the dried impurities in the internal medicinal slices fall into the collection frame 301 through the bottom of the material frame 201, and the impurities screened in the medicinal slices are collected to avoid the need for subsequent unified processing of the collected impurities.
[0030] The drawer body 2 includes a material frame 201, a first limiting plate 202, and a sealing plate 203. The material frame 201 is slidably connected inside the support frame 5. The first limiting plate 202 is fixedly installed on the outer wall of the material frame 201 and slidably connected to the outer wall of the drying oven body 1. The sealing plate 203 is limited and fitted against the inner wall of the drying oven body 1. It should be noted that a certain space is left between the material frame 201 and the front end of the drying oven body 1 to facilitate the support frame 5 to move the material frame 201 back and forth inside the drying oven body 1. For details, please refer to the appendix. Figure 4 When the material frame 201 is inside the support frame 5, the first limiting plate 202 is attached to the outer wall of the drying chamber body 1, which can block and seal the connection between the material frame 201 and the drying chamber body 1, ensuring that the inside of the drying chamber body 1 is kept at a high temperature. At the same time, when the material frame 201 is removed from the inside of the drying chamber body 1, the second spring 2031 resets, which can make the sealing plate 203 be limited and locked onto the inner wall of the drying chamber body 1, and can seal the connection between the drying chamber body 1 and the material frame 201, ensuring that the inside of the drying chamber body 1 is sealed when the dried material is unloaded.
[0031] The sealing plate 203 and the material frame 201 are on the same horizontal plane. A second spring 2031 is fixedly connected to the outer wall of the material frame 201, and the sealing plate 203 is fixedly connected to the second spring 2031. A driving component 2032 is slidably connected to the inner wall of the material frame 201. One end of the driving component 2032 passes through the inner wall of the material frame 201 and is fixedly connected to the sealing plate 203. During the feeding process of a set of dried materials, the material frame 201 detaches from the support frame 5. The support plate 2033 supports the detached material frame 201. For details, please refer to the appendix. Figure 9 The other material boxes 201 are located inside the drying chamber body 1, and with the cooperation of the drive component 6, they can automatically slide back and forth inside the drying chamber body 1, loading and unloading materials at different times to ensure the heat loss inside the drying chamber body 1, thereby reducing energy consumption and drying costs.
[0032] A support plate 2033 is fixedly installed on the inner wall of the drying oven body 1, supporting the material frame 201. The support plate 2033 is located on the outer wall of the front end of the support frame 5. The waste collection assembly 3 includes a collection frame 301 and a second limiting plate 302. The collection frame 301 is slidably connected inside the drying oven body 1, and the second limiting plate 302 is fixedly installed on the outer wall of the collection frame 301. The second limiting plate 302 is attached to the outer wall of the drying oven body 1. When the material frame 201 is installed inside the support frame 5, the outer walls of the material frame 201 and the sealing plate 203 are respectively attached to the inner wall of the support frame 5. At the same time, the second spring 2031 is in a compressed state. For details, please refer to the appendix. Figure 8When it is necessary to detach the material frame 201 from the support frame 5, the first limiting plate 202 is pulled outward, causing the material frame 201 to slide inside the support frame 5. After the material frame 201 is completely detached from the support frame 5, the second spring 2031 extends and retracts, which will automatically drive the sealing plate 203 to rebound to one side and automatically limit and fit against the inner wall of the drying oven body 1. When the material frame 201 is pushed into the support frame 5, the sealing plate 203 can be moved by the driving component 2032, so that the material frame 201 can be installed inside the support frame 5. It should be noted that magnets are respectively provided on the inner wall of the support frame 5 and the outer wall of the material frame 201, which can fix the material frame 201 inside the support frame 5.
[0033] The outer walls of the support frame 5 are respectively fixedly connected with a first spring 501 and a second triangular block 502. Multiple sets of first springs 501 are equidistantly distributed along the outer wall of the support frame 5. One end of the first spring 501 is fixedly connected to the inner side wall of the drying oven body 1. The drive assembly 6 includes a fixed frame 601, a rotary motor 602, a drive shaft 603, a first triangular block 604 and a fixed plate 605. The fixed frame 601 is fixedly installed on the outer side wall of the drying oven body 1. The rotary motor 602 is fixedly installed on the top of the fixed frame 601. The drive shaft 603 is rotatably connected inside the fixed frame 601. When the material frame 201 is detached from the inside of the support frame 5, the rotary motor 602 is in a non-working state, and the support frame 5 drives the material frame 201 to slide back and forth.
[0034] The output end of the rotary motor 602 is fixedly connected to the drive shaft 603. The fixing plate 605 is fixedly sleeved on the outer peripheral wall of the drive shaft 603. Multiple sets of fixing plates 605 are equidistantly distributed along the axial direction of the drive shaft 603. The first triangular block 604 is fixedly installed on the outer wall of the fixing plate 605. The first triangular block 604 is located on one side of the second triangular block 502. By starting the rotary motor 602, the rotary motor 602 drives the drive shaft 603 to rotate inside the fixing frame 601, thereby driving multiple sets of first triangular blocks 604 to rotate simultaneously. This causes multiple sets of first triangular blocks 604 to contact multiple sets of second triangular blocks 502, generating a thrust on the support frame 5. With the cooperation of the first spring 501, multiple sets of support frames 5 can be driven to slide back and forth inside the drying oven body 1 at the same time, dispersing the material inside the material frame 201, so that the top baking component 4 can bake the material evenly and improve the baking efficiency.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
