[0002] Nanomaterials refer to materials that have at least one dimension in the three-dimensional space at nanometer size or are composed of them as basic units. They are natural or artificial materials in powdery or lumpy form composed of basic particles. In the process of processing nanomaterials, they need to be dried. Due to the small size of nanomaterials, air drying is usually used to quickly dry nanomaterials, and drying equipment is needed in the process of drying nanomaterials.

[0003] However, the existing nanomaterial drying equipment still has certain defects when used; For example, a nanomaterial production drying device proposed in application number CN202211196299.3 includes a bottom plate, a first support plate and a second support plate fixed on the bottom plate, and also includes a drying cylinder, a collecting cylinder, a heating cylinder, a motor, an electric heating wire and a connecting groove; both ends of the drying cylinder are fixed with connecting sleeves, and the two connecting sleeves are rotatably connected to the first support plate and the second support plate respectively, the heating cylinder is rotatably connected in the drying cylinder, the electric heating wire is fixed in the heating cylinder, the nanomaterial in the drying cylinder enters the collecting cylinder, and when the drying cylinder drives the collecting cylinder to move upward, the nanomaterial in the collecting cylinder falls from the connecting groove to the heating cylinder, and the heating cylinder heats and dries the nanomaterial, so that the nanomaterial falls downward along the outer wall of the heating cylinder, and then the nanomaterial is evenly in contact with the outer wall of the heating cylinder. In actual use, the following problems still exist: The nanomaterial production drying device uses the rotation of the drying drum to dry the nanomaterials inside during the drying process. However, due to the small size of the nanomaterials, the nanomaterials are prone to uneven dispersion during the rotation of the drying drum, which will reduce the drying uniformity and effect. In the nano material production drying device, the discharge work is realized by opening the material port. However, in the process of discharging, the fine nano materials are easy to adhere to the inner wall, which will lead to incomplete discharging and blockage, reducing the discharging effect.

[0004] In view of this, we conducted in-depth research on the above issues, which led to the present case.

[0005] In view of the above problems, an innovative design is made based on the original flow-type uniform drying equipment for nanomaterials which is convenient for heat circulation. Summary of the invention
