Description

Technical Field

[0001] The utility model relates to the technical field of traditional Chinese medicine drying, and particularly relates to a belt dryer for traditional Chinese medicine. Background Art

[0002] The belt dryer for traditional Chinese medicine is a device specially designed for drying traditional Chinese medicine. It adopts a continuous belt conveyor mode for drying treatment and is widely used in the drying operations of various traditional Chinese medicines. This dryer is very popular in the field of traditional Chinese medicine processing due to its significant advantages such as high efficiency, energy saving, and environmental protection.

[0003] The working principle of the belt dryer is to evenly spread traditional Chinese medicine on the conveyor belt and uniformly heat and dry the material through hot air circulation. The conveyor belt moves forward at a constant speed to ensure that the traditional Chinese medicine can be evenly heated during the drying process, thereby achieving an ideal drying effect. In addition, the belt dryer also has the function of flexibly adjusting parameters such as hot air temperature, humidity, and conveyor belt speed to adapt to the characteristics and drying requirements of different traditional Chinese medicines.

[0004] However, although the belt dryer performs well in traditional Chinese medicine processing, the selection and use of the conveyor belt still face many challenges. Due to the wide variety of traditional Chinese medicines, their volumes, shapes, and drying requirements are different, which brings many difficulties to the design and use of the conveyor belt.

[0005] For traditional Chinese medicines with a larger volume, the conveyor belt usually needs to be designed with gaps to achieve multi-sided drying and dropping debris. This design helps to increase the contact area between the traditional Chinese medicine and hot air, thereby improving the drying efficiency. However, the existence of gaps also increases the risk of deviation and dropping of traditional Chinese medicine during transmission, which may lead to raw material loss and instability of the drying process.

[0006] For traditional Chinese medicines with a smaller volume, a conveyor belt without gaps is usually selected for conveying. Although this design helps to reduce the possibility of the medicine dropping, due to the large contact area between the medicine and the conveyor belt, it may lead to uneven drying, thereby affecting the drying effect. In addition, the conveyor belt without gaps may also be more cumbersome in terms of cleaning and maintenance.

[0007] Whether it is a conveyor belt with gaps or without gaps, there is a risk of deviation and dropping of traditional Chinese medicine during transmission. This is mainly due to the diversity of traditional Chinese medicines, the limitations of conveyor belt design, and the uncertainties during the operation process. Therefore, in practical applications, it is necessary to reasonably select and adjust the conveyor belt according to the characteristics and drying requirements of traditional Chinese medicines to optimize the drying effect and reduce unnecessary losses. Summary of the Utility Model

[0008] The main object of the present utility model is to provide a belt dryer for Chinese medicinal materials, which can effectively solve the problems raised in the background art.

Detailed Embodiments

[0028] To make the technical means, creative features, achieved purposes and effects of this utility model easy to understand, the following further elaborates this utility model in combination with specific embodiments. Embodiment

[0029] As shown Figures 1-5 in the figure, a belt dryer for traditional Chinese medicinal materials has the following structural features and functions. The machine mainly includes key components such as a bracket 1, a control box 2, a protective frame 3, a tunnel oven 4, a circulation pipeline 5, a heating device 6, a transmission assembly 7, and a chain-type transmission roller 8, etc.

[0030] In the overall layout, the protective frame 3 and the control box 2 are firmly installed on the bracket 1. The protective frame 3 is located at the top of the bracket 1, playing a role in protecting the internal mechanical structure. The chain-type transmission roller 8 is cleverly installed on the protective frame 3 through the transmission assembly 7 to ensure its stable and efficient operation during the working process.

[0031] In addition, the tunnel oven 4 and the heating device 6 are also carefully installed on the protective frame 3. They are closely connected through the circulation pipeline 5 to form a complete heating circulation system. The heat generated by the heating device 6 is continuously transported to the tunnel oven 4 through the circulation pipeline 5 to provide the necessary heat energy for drying traditional Chinese medicinal materials.

[0032] In the design of the chain-type transmission roller 8, a set of belts 9 are sleeved on both sides of it, and a plurality of connecting soft blocks 10 are connected to the surface of the set of belts 9. These connecting soft blocks 10 can not only effectively prevent the traditional Chinese medicinal materials from shifting during the transmission process, ensuring that the traditional Chinese medicinal materials can move forward stably along the chain-type transmission roller 8, but also their soft characteristics can effectively reduce the damage to the traditional Chinese medicinal materials.

[0033] It is worth mentioning that the structure of the chain-type transmission roller 8 is quite unique. It is composed of multiple transmission rollers and chains. The transmission rollers are equally spaced between the two chains. Such a design allows sufficient gaps between each transmission roller, so that the debris and dust particles on the traditional Chinese medicinal materials can be easily discharged, maintaining the cleanliness and hygiene of the entire transmission process.

[0034] As the core component for driving the operation of the chain-type transmission roller 8, the transmission assembly 7 has a quite precise structure. It consists of components such as a gear disk, a bearing device, and a rotating shaft, etc. The rotating shaft is inserted into the bearing device and tightly connected to the gear disk, thereby realizing the precise drive of the chain-type transmission roller 8. The bearing device is firmly fixed on the protective frame 3 through fasteners such as bolts and nuts to ensure the stability and reliability of the entire transmission process.

[0035] In the design of the connecting soft blocks 10, a plurality of connecting soft blocks 10 are equally spaced on the set of belts 9 and are fixed on the set of belts 9 by adhesion. Such a layout method not only makes the entire conveyor belt more flat and stable, but also can effectively improve the transmission efficiency of traditional Chinese medicinal materials. Embodiment

[0036] This embodiment is further optimized and improved on the basis of Embodiment 1, mainly reflected in the design of the connecting soft block 10.

[0037] At the upper end of the connecting soft block 10, an arc-shaped retaining bar 11 is added. The arc-shaped retaining bar 11 and the connecting soft block 10 are integrally designed, which not only enhances the stability of the overall structure, but also makes the blocking effect of the connecting soft block 10 more significant. At the same time, the cross-section of the arc-shaped retaining bar 11 and the connecting soft block 10 is designed in a "herringbone" shape, which enables the Chinese herbal medicines to be better restricted in the specified position during the conveying process, preventing them from shifting or falling.

[0038] In addition, an arc-shaped retaining cover 12 is added to the inner wall of the connecting soft block 10. The arc-shaped retaining cover 12 is designed in a "C" shape and is fixed to the connecting soft block 10 by hot melting. Such a design can not only further enhance the blocking effect of the connecting soft block 10, but also effectively prevent the debris or dust particles generated during the conveying process of the Chinese herbal medicines from entering the inside of the connecting soft block 10, thus keeping the entire conveyor belt clean and hygienic. Embodiment

[0039] This embodiment further improves the applicability and flexibility of the equipment on the basis of Embodiment 2.

[0040] First of all, this embodiment optimizes the driving mode of the chain-driven roller 8 so that it can better adapt to Chinese herbal medicines of different specifications and weights. By adjusting the parameters of the gear disc and bearing device in the driving component 7, precise control of the rotation speed of the chain-driven roller 8 can be achieved, so as to meet the drying requirements of different Chinese herbal medicines.

[0041] Secondly, this embodiment also improves the fixing method of the sleeved belt 9. By using fasteners such as bolts to firmly fix the sleeved belt 9 on the chain-driven roller 8, not only the stability and durability of the entire conveyor belt are improved, but also the entire equipment is easier to maintain and service.

[0042] In addition, this embodiment also adds a plurality of small Chinese herbal medicine placement areas in the equipment. These placement areas are realized by covering the entire chain-driven roller 8 with a plurality of sleeved belts 9, so that small Chinese herbal medicines can be more evenly and stably distributed on the conveyor belt, thereby improving the drying effect and product quality.

[0043] Drying process: During the drying process of Chinese herbal medicines, first, the Chinese herbal medicines are placed on the sleeved belt 9 of the chain-driven roller 8. With the drive of the driving component 7, the chain-driven roller 8 starts to rotate, driving the sleeved belt 9 and the Chinese herbal medicines on it to move forward. During this process, the Chinese herbal medicines are dried by the tunnel oven 4.

[0044] The tunnel oven 4 is connected to the heating device 6 through the circulation pipeline 5. The heat generated by the heating device 6 is transported to the interior of the tunnel oven 4 through the circulation pipeline 5, providing the necessary heat energy for the Chinese medicinal materials. The Chinese medicinal materials gradually lose moisture under the continuous action of hot air in the tunnel oven 4 and achieve the purpose of drying.

[0045] During the drying process, the connecting soft blocks 10 play a key role. They are equidistantly distributed on the sleeved belt 9 and can effectively prevent the Chinese medicinal materials from shifting during the conveying process, ensuring that the Chinese medicinal materials can steadily advance along the chain-type transmission roller 8. At the same time, the soft characteristics of the connecting soft blocks 10 can also effectively reduce the damage to the Chinese medicinal materials.

[0046] In addition, the design of the chain-type transmission roller 8 also fully considers the drying requirements of the Chinese medicinal materials. The gap between the transmission roller and the chain can easily discharge the debris and dust particles on the Chinese medicinal materials, keeping the entire conveying process clean and hygienic, thereby ensuring the drying quality of the Chinese medicinal materials.

[0047] During the conveying process of the Chinese medicinal materials, in order to prevent them from falling, the equipment adopts multiple blocking measures. First of all, the connecting soft blocks 10 serve as the main blocking equipment. Through their design of being equidistantly distributed on the sleeved belt 9, a continuous blocking surface is formed. When the Chinese medicinal materials move on the conveyor belt, the connecting soft blocks 10 can effectively block the offset of the Chinese medicinal materials and ensure their stable advancement.

[0048] In addition, the arc-shaped blocking strips 11 added to the upper end of the connecting soft blocks 10 further enhance the blocking effect. The arc-shaped blocking strips 11 and the connecting soft blocks 10 are integrally designed, not only with stable structure but also better able to limit the position of the Chinese medicinal materials. When the Chinese medicinal materials come into contact with the arc-shaped blocking strips 11, due to their "herringbone" design, the Chinese medicinal materials will be effectively restricted in the specified position to prevent them from continuing to shift or fall.

[0049] In addition, the arc-shaped blocking covers 12 added to the inner walls of the connecting soft blocks 10 also play a role in preventing the Chinese medicinal materials from falling. The arc-shaped blocking covers 12 are designed in a "C" shape and are closely attached to the connecting soft blocks 10, forming a closed protection space. This can not only prevent the Chinese medicinal materials from falling through the gaps of the connecting soft blocks 10 but also effectively prevent the debris or dust particles generated during the conveying process of the Chinese medicinal materials from entering the interior of the connecting soft blocks 10, keeping the conveyor belt clean and hygienic.

[0050] The standard parts used in the present utility model can all be purchased from the market. The special-shaped parts can be customized according to the records in the specification and the drawings. The specific connection methods of each part all adopt the mature conventional means such as bolts, rivets, and welding in the prior art.
