Description

Technical Field

[0001] The utility model relates to the technical field of a circulating hot air drying oven for granular medicinal materials, and more specifically, to a circulating hot air drying oven for granular medicinal materials. Background Art

[0002] In the existing technology, the circulating hot air oven for granular medicinal materials plays a vital role in the drying process. However, this equipment faces a significant problem during use. First of all, due to design limitations, the existing circulating hot air ovens are often unable to conveniently adjust the position of the ventilation disk when dealing with different medicinal material drying needs. This means that when the position of the ventilation disk needs to be adjusted according to the characteristics of the medicinal materials and the drying requirements, the operator often faces certain difficulties. This inconvenience not only reduces the drying efficiency, but may also affect the drying quality and consistency of the medicinal materials, thereby having a negative impact on the overall use effect.

[0003] Furthermore, due to the inadequacy of the existing circulating hot air oven in adjusting the position of the ventilation disc, it limits the ability of the equipment to be applied in diverse and complex drying environments. In actual operation, different medicinal materials may require different ventilation conditions to achieve the desired drying effect. If the position of the ventilation disc cannot be flexibly adjusted, it may cause some medicinal materials to be over-dried or under-dried, affecting the quality and efficacy of the medicinal materials. In addition, this inconvenience of adjustment may also increase production costs because more time and labor are required to adjust the equipment to adapt to different drying requirements.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a circulating hot air drying oven for granular medicinal materials, which has the following beneficial effects:

[0017] 1. The design of the adjustment mechanism allows the operator to flexibly adjust the spacing of the ventilation discs according to different medicinal material drying requirements. By applying pressure to the vertical frame through the push spring, the operator can easily adjust the position of the ventilation disc. In addition, by pressing on the push sleeve so that the one-way sheet is stuck in different annular grooves, the compression amount of the push spring can be changed, and then the pressure of the spring can be changed, thereby achieving precise adjustment of the spacing of the ventilation discs. This design not only improves the flexibility of adjustment, but also ensures the adaptability and drying effect of the oven during the drying of different medicinal materials.

[0018] 2. The clamping mechanism fixes the distance between the ventilation discs through the cooperation of the insertion block and the threaded ring. When the distance between the ventilation discs needs to be adjusted, the unlocking sleeve is pressed on the one-way plate to release the clamping between the one-way plate and the annular groove. This mechanism ensures the stability and reliability of the ventilation disc during the adjustment process.

[0019] 3. The circulation mechanism realizes the circulation of hot air and the continuous drying process through the cooperation of the fan, circulation pipe and sealing door. The fan introduces the external hot air into the shell and dries the medicinal materials through the ventilation plate. The circulation pipe passes the hot air from the upper end to the lower end to form a circulating drying process. This design not only improves the uniformity and efficiency of drying, but also ensures the hot air circulation effect inside the oven, thereby providing reliable and efficient support for the drying of medicinal materials.
