[0002] A blast drying oven is a device that dries materials by circulating hot air. It is widely used in electromechanical, pharmaceutical, food, light industry and other industries to dry or heat treat various materials or samples.

[0003] As we all know, a blast dryer is a commonly used drying equipment. When the existing blast drying box is in use, the material to be dried is added into the blast drying box, a stable temperature is maintained in the blast drying box, and the moisture in the material is continuously dried out, thereby achieving the effect of drying the material.

[0004] However, the position of the carrier plate for placing the material tray inside the existing blast dryer is fixed. When drying or heat treating, the position of the carrier plate cannot be adjusted according to the size of the material. The material tray can only be placed at a fixed position, which reduces the efficiency of material drying or heat treating.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model sets threaded rods, carrier plate 1, connecting rods and other components, and meshes gears with toothed belts to make four threaded rods rotate synchronously, and the threaded rods drive the corresponding carrier plate 1 to rise and drive the corresponding connecting rod to rise. When the carrier plate 1 rises to a certain height, the positioning groove 2 provided inside the carrier plate 2 below the carrier plate 1 contacts the connecting rod to make the corresponding carrier plate 2 rise, and so on, to achieve equidistant distribution of the carrier plate 1 and the carrier plate 2, and at the same time, the corresponding number of carrier plates 1 and 2 can be raised according to actual usage, so as to achieve the effect of adjusting the positions of the carrier plate 1 and the carrier plate 2 according to the required drying materials.

[0016] 2. The utility model sets a fixed block, a fixed plate, an elastic rod and other components, and drives the elastic rod into the corresponding limit groove through the protective plate. At the same time, the protective plate contacts the fixed plate and makes the fixed plate compress the spring and the telescopic rod. When the elastic rod reaches the end of the limit groove, the telescopic rod and the fixed plate are driven to move by the spring rebound, and the fixed plate pushes the protective plate to make the elastic rod enter the groove of the limit groove, thereby locking and completing the installation of the protective plate. By pressing the protective plate again, the protective plate pushes the fixed plate to compress the spring, so that the elastic rod leaves the groove of the limit groove and enters the end of the limit groove on the other side to unlock the protective plate. At the same time, the protective plate is pulled outward to complete the removal of the protective plate, thereby achieving the effect of facilitating the installation and removal of the protective plate and facilitating maintenance.
