[0028] Through the drying mechanism 4, the blower 44 is used to blow air into the heating box 41, so that the airflow transports the hot air generated by the heating rod 42 to the diverter pipe 47 through the conduit 46, and then blows it into the drying cylinder 1 by the nozzle 48, so as to facilitate the drying of the fluororesin particles in the cylinder, and then dry them evenly, thereby shortening the drying time. Through the exhaust mechanism 6, when the hot air enters the drying cylinder 1 to dry the fluororesin particles, the rotating exhaust fan blades 64 can be used to attract the hot air in the cylinder and discharge it from the drying cylinder 1. In the process of discharge, the moisture in the fluororesin particles can be taken away, and at the same time, the flow of hot air in the drying cylinder 1 is increased, which helps to improve the drying efficiency.

[0029] like Figure 3 As shown, the stirring assembly 3 includes a motor 31, the lower end of the motor 31 is fixedly connected to the middle of the top of the drying cylinder 1, and a rotating rod 32 is rotatably connected to the middle of the interior of the drying cylinder 1, and multiple groups of stirring rods 33 are fixedly installed on the outer surface of the rotating rod 32.

[0030] The top of the rotating rod 32 is drivingly connected to the output end of the motor 1 31 .

[0031] The stirring rod 33 can stir and move the fluororesin particles in the drying cylinder 1, thereby increasing the fluidity of the fluororesin particles, increasing the contact area between the fluororesin particles and the hot air, and improving the drying effect.

[0032] like Figure 4 As shown, the drying mechanism 4 includes a heating box 41, the left end of the heating box 41 is movably connected to the right end of the drying cylinder 1, a plurality of groups of heating rods 42 are evenly and fixedly installed inside the heating box 41, support columns 43 are symmetrically and fixedly installed at the four corners of the left end of the heating box 41, the right end of the heating box 41 is connected to a connected blower 44, mounting seats 45 are symmetrically and fixedly installed on both sides of the left end of the blower 44, a connected duct 46 is fixedly installed on the left end of the heating box 41, a connected diverter pipe 47 is fixedly installed on the top of the duct 46, and a plurality of groups of nozzles 48 are evenly and fixedly installed on the left end of the diverter pipe 47.

[0036] The working principle of the drying device for producing fluororesin particles will be described in detail below.

[0037] like Figure 1-5 As shown, when the drying device for producing fluororesin particles is used, the fluororesin particles can first be put into the drying cylinder 1 through the feed hopper 2, and then the heating rod 42 and the blower 44 can be started. The heating rod 42 will generate heat after being energized, and the blower 44 can blow air into the heating box 41, so that the airflow can blow the heat generated by the heating rod 42 into the conduit 46, and the heat is formed into hot air. After entering the conduit 46, the hot air will enter the diverter pipe 47 through the conduit 46, and finally be sprayed into the drying cylinder 1 through the nozzle 48, so that the fluororesin particles in the drying cylinder 1 can be dried. At the same time, the motor 31 can be started, and the motor 31 drives the motor 31 to drive ... The rotating rod 32 rotates, so that the rotating rod 32 drives the stirring rod 33 to rotate synchronously, and then the fluororesin particles in the drying cylinder 1 can be stirred, so that the fluororesin particles flow in the drying cylinder 1, so that the fluororesin particles can be evenly dried. At the same time, the motor 2 63 can be started, and the motor 2 63 drives the exhaust fan blades 64 to rotate. When the exhaust fan blades 64 rotate, they can absorb the hot air in the drying cylinder 1 through the exhaust holes 65 and discharge it, thereby directly increasing the fluidity of the hot air in the drying cylinder 1. At the same time, the moisture in the fluororesin particles can be discharged from the drying cylinder 1, thereby improving the drying speed of the fluororesin particles, and the drying efficiency is high and the effect is good.
