Description

Technical Field

[0002] In the process of producing chemical products, for various purposes, it is often necessary to dry materials with high moisture content to reduce moisture. In various environments, the moisture content of the material plays a vital role in the process and results of the chemical reaction, so whether the drying degree is sufficient is also crucial. The Chinese utility model patent with application number 202322116010.9 provides a device for drying chemical products, which can use a driving component to drive a flipping plate to flip the chemical products in the drying box, so as to achieve uniform heating. However, the flipping plate is fixed to the belt, that is, the flipping plate is supported only by the belt. When the weight of the flipped material is large, the flipping plate is difficult to bear, and it is easy to cause the belt to deform, thereby reducing the flipping effect. When the material is in the gap formed between the flipping plate, the belt and the middle part of the drying box, the hot air delivered by the fan is difficult to fully circulate here, so it is difficult to fully dry the material in this part, reducing the drying effect. When the material is fine, the material is easy to enter the gap between the belt and the rotating shaft, thereby affecting the stability of the belt and the rotating shaft transmission, highlighting its shortcomings.
