Description

Technical Field

[0001] The utility model relates to the technical field of straw drying, in particular to a straw drying device for straw carbonization. Background Art

[0002] Straw carbonization is a process that converts straw into charcoal. The main steps include drying or sun-drying the straw, crushing it, and then drying, distilling and cooling it in charcoal-making equipment. Distillation is the core process of straw carbonization. Through this process, loose straw is converted into charcoal.

[0003] A common drying method is to use the rotation of the drying drum and the continuous injection of hot air to quickly dry the straw. In this case, the opening position of the drying drum is responsible for loading and unloading, and the switching of loading and unloading is achieved by changing the rotation direction of the drying drum. With the injection of hot air, the circulation speed of the air inside is accelerated, and the straw inside is constantly rolling, causing the raised dust to continuously overflow from the opening. At the same time, dust overflow will also occur during loading and unloading. If it is not handled in time, the working environment will deteriorate, causing physical injury to personnel.
