By setting up components such as an air pump, an exhaust pipe, a motor, a rotating shaft and a stirring plate, the heating plate, the motor and the air pump are started before the material is introduced. The motor drives the rotating shaft, and the rotating shaft drives multiple stirring plates and cross bars. The stirring plate makes the material tumble, so that the contact area between the material and the hot air is wider, and the material can be heated more evenly. The air pump inhales the gas from the intake pipe and introduces it into the tank body through the exhaust pipe, which can make the hot air in the tank body fluid, thereby improving the drying speed of the equipment.

Therefore, it is necessary to ensure that the turning time is certain to avoid the possibility of uneven drying of the silicon carbide micropowder, thereby reducing the drying efficiency and increasing the drying time. For this reason, a silicon carbide micropowder drying device is proposed to solve the above problems. Utility Model Content

The fan blade 8 is provided with four groups, and the four groups of fan blades 8 are distributed in groups of two and are located at the top of the sieve plate 11 and the top of the discharge port 3. The inner wall of the fan blade 8 is rotatably connected with a support shaft 9, and the outer wall of the support shaft 9 is fixedly connected with a volute spring 10. The inner wall of the drying tank 1 is fixedly connected with a sieve plate 11, and the top of the sieve plate 11 is fixedly connected with a protrusion 12. The inner wall of the drying tank 1 is fixedly connected with a protrusion rod 13. The promotion assembly includes an air pump 14, and the output end of the air pump 14 is fixedly connected with an air delivery pipe 15.

An air outlet pipe 16 is provided on the top of the drying tank 1, and a one-way valve 17 is provided on the surface of the air outlet pipe 16. The setting of the one-way valve 17 enables the air outlet pipe 16 to only discharge the gas in the drying tank 1, and prevents the outside gas from entering, thereby ensuring the air pressure balance inside the drying tank 1. The end of the support shaft 9 is fixedly connected to the outer wall of the rotating shaft 6, and the end of the volute spring 10 away from the support shaft 9 is fixedly connected to the inner wall of the fan blade 8, the outer wall of the air pump 14 is fixedly connected to the upper surface of the drying tank 1, and the air supply pipe 15 runs through the interior of the drying tank 1.

[0035] Reference Figure 5-Figure 6 The bottom end of the rotating shaft 6 is fixedly connected to a supporting shell 21, and an electric push rod 22 is fixedly connected to the inner wall of the supporting shell 21.

At the same time, the sieve plate 11 can pre-screen the silicon carbide powder when drying. When the fan blades 8 in groups of two rotate to contact the inverted convex block 12 and the convex rod 13, the extrusion force will cause the fan blades 8 to rotate, and at this time the scroll spring 10 gradually stretches and deforms. The silicon carbide powder on the surface of the sieve plate 11 and the bottom of the drying tank 1 is turned over by the fan blades 8 to avoid the silicon carbide powder at the bottom from accumulating and being difficult to contact the heat source for drying. At this time, the transmission belt 18 drives the pipeline to rotate, and the nozzle 20 sprays gas in a rotating state inside the drying tank 1, expanding the area of ​​the jet so that the flow speed of the hot gas inside the drying tank 1 is increased. When the dry contact is completed, the motor 5 is still in the starting state. At this time, the electric push rod 22 is turned on, and the electric push rod 22 reciprocates to drive the auxiliary shaft 23 to rise and fall inside the drying tank 1, so that the spiral blade 24 is lifted and rotated to assist the silicon carbide powder in discharging, thereby increasing the discharging speed of the silicon carbide powder after drying.
