[0024] like Figures 1 to 3 As shown, the utility model provides a rapid material drying device, including a bottom mounting frame 1 and a top mounting frame 2, the lower end of the top mounting frame 2 is fixed to the upper end surface of the bottom mounting frame 1, and a drying assembly 3 is provided on the bottom mounting frame 1 and the top mounting frame 2, and the drying assembly 3 on the top mounting frame 2 and the bottom mounting frame 1 are arranged opposite to each other. The drying assembly 3 includes several groups of drying mechanisms arranged side by side, and the drying mechanism includes a funnel-shaped shell 5, and the large diameter end of the funnel-shaped shell 5 located at the bottom drying structure is provided with evenly distributed supporting rods 8, both ends of the supporting rods 8 are fixed to the inner wall of the funnel-shaped shell 5, and a heating device 6 is provided on the outer surface of the small diameter end of the funnel-shaped shell 5, one end of the heating device 6 is communicated with the interior of the funnel-shaped shell 5, and the other end of the heating device 6 is provided with a blowing device 7, and the air outlet end of the blowing device 7 is communicated with the other end of the heating device 6, and the large diameter end of the funnel-shaped shell 5 is arranged toward the connection between the bottom mounting frame 1 and the top mounting frame 2, which can also be understood as being arranged toward the middle of the mounting frame 1.

[0025] The working principle of this technical solution is:

[0026] Place the material receiving basket 9 on the work surface and start the rapid material drying device. The intelligent control system automatically adjusts the heating temperature and blower speed according to the material type and drying requirements. The upper and lower blowers 7 (blowers) work simultaneously to provide forced convection air and accelerate the drying process. After drying is completed, the device is closed and the receiving basket 9 is removed. It is not difficult to understand that the device is equipped with a temperature sensor and an overheating protection device to ensure safe operation of the equipment.

[0027] In one practicable embodiment, the heating device 6 includes a closed housing 10, one end of which is connected to the small-diameter end of the funnel-shaped housing 5, and the other end of which is connected to the air outlet of the blasting device 7. A plurality of electric heating plates 11 are provided inside the closed housing 10. The electric heating plates 11 are electric heating devices that wrap a resistance heating wire around a mica board (mica sheet) and have advantages such as high temperature resistance and good insulation performance. The blasting device 7 includes a mounting housing 12, which is provided with an air inlet 15. A drive motor 14 is provided on the outer wall of the mounting housing 12. The drive motor 14 is fixed to the mounting housing 12, and the output end of the drive motor 14 is located inside the mounting housing 12. The output end of the drive motor 14 is provided with a plurality of blades 13 evenly distributed around the circumference.

[0028] The driving motor 14 rotates, driving the blades 13 to rotate and thus forming wind force. The wind acts on the electric heating plate 11, carrying heat to the upper end of the funnel-shaped shell 5, and then drying the material. Of course, it is not difficult to understand that it should also include a control box 4. The control box 4 is a prior art and is equipped with an intelligent control system inside. It can automatically adjust the heating temperature and blower wind speed according to the type, thickness and drying requirements of the material to achieve precise drying. The specific implementation method is common knowledge of those skilled in the art and will not be elaborated on here.

[0029] In one practicable embodiment, the bottom mounting frame 1 includes a plurality of support legs 19 arranged in a rectangular pattern, with a crossbeam 18 connecting two adjacent support legs 19. The funnel-shaped housing 5 of the drying mechanism mounted on the bottom mounting frame 1 is fixed to the crossbeam 18. The top mounting frame 2 includes symmetrically arranged columns 17, one end of each column 17 being fixed to the bottom mounting frame 1, and a fixing frame 16 being provided on the other end of each column 17. The fixing frame 16 is fixed to the other end of each column 17, and the funnel-shaped housing 5 of the drying mechanism mounted on the top mounting frame 2 is fixed to the fixing frame 16. Of course, the top mounting frame 2 and the bottom mounting frame 1 can be integrated into a single unit.

[0030] In one possible implementation, the uprights 17 are retractable. This retraction can be achieved by a telescopic rod, a linear motor, or a hydraulic cylinder. The advantage of this retractable arrangement is that the relative height of the drying assembly 3 can be adjusted, and thus adjusted according to the drying wind speed, ensuring convection. High wind speeds can be achieved with a relatively long distance, while low wind speeds require a closer distance. Of course, it's also readily apparent that curtains could be provided on the exterior of the upper and lower funnel-shaped housings 5 to prevent excessive heat from escaping and reducing drying efficiency.

[0031] In one embodiment, a receiving basket 9 is provided above the drying assembly 3 mounted on the bottom mounting frame 1, and is used in conjunction with the funnel-shaped housing 5. The receiving basket 9 is hollowed out and placed on the support rod 8. The hollowed-out arrangement (forming a mesh) allows for convective wind energy to act on the material. It is readily understood that those skilled in the art should understand that the mesh diameter of the receiving basket 9 should be smaller than the material to prevent it from falling. The combination of the drying assembly 3 and the mesh receiving basket 9 ensures that the hot air acts on the material surface, allowing the material to be heated evenly during the drying process, thus avoiding quality issues caused by uneven drying.

[0032] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
