Problems solved by technology

Among them, the blast drying is to blow out the hot air through the circulating fan to achieve the purpose of dry drying, but the blast drying is very easy to make the chemical materials in the drying device mixed with impurities, which reduces the production quality of the chemical materials, and now Some drying devices, after drying, the material is easy to agglomerate, which is not conducive to unloading, and the drying effect is poor at the same time
[0003] Chinese patent (authorized announcement number: CN210718449U) discloses a drying device for chemical materials, in which an air compartment is formed between the inner cylinder and the outer cylinder, and high-temperature steam can be passed into the air compartment through the intake pipe to heat the inner cylinder. It achieves the purpose of drying and avoids direct contact between steam and chemical materials, thereby ensuring the purity of chemical materials; however, this patent also has certain technical defects, and there is also a problem of hot air outflow while water vapor is discharged; thus causing heat loss , the drying degree of the material is not enough

Description

technical field [0001] The invention relates to the field of chemical production, in particular to a chemical material drying device. Background technique [0002] At present, the drying device mainly vaporizes and escapes the moisture (generally referring to water or other volatile liquid components) in the material by heating to obtain a solid material with a specified moisture content. In many chemical solid products, moisture is strictly controlled. Therefore, it is necessary to use a drying device to make the product meet the requirements. Generally, the laboratory uses a drying oven to dry the experimental samples. The drying oven is divided into two types: blast drying and vacuum drying. Among them, the blast drying is to blow out the hot air through the circulating fan to achieve the purpose of dry drying, but the blast drying is very easy to make the chemical materials in the drying device mixed with impurities, which reduces the production quality of the chemical m...
