[0028] The side of the tank body 1 is clamped with a cover plate 6; for example, as shown in Figures 2-5 .

[0029] The inner side of the cover plate 6 is provided with a protective ring 7, the protective ring 7 is an integrally formed rubber ring, and the side of the protective ring 7 is in movable contact with the pushing plate 42.

[0030] The outer surface of the tank body 1 is attached with an electric heating wire 9, and the shape of the electric heating wire 9 is a spiral concentric ring.

[0031] One end of the first screw rod 41 is adapted to be mounted with a driving motor 8, the driving motor 8 is adapted to be mounted with the tank body 1 through a fixing block, and the other end of the first screw rod 41 is fixed with a second screw rod 10, and the outer surface of the second screw rod 10 is sleeved with a clamping seat 11.

[0032] Specifically, through the movable contact of the protective ring 7 and the push plate 42, the displacement movement of the push plate 42 is limited inside the protective ring 7, which is also beneficial to the safe filling of the powder, prevents overfilling, and the outer surface of the tank body 1 is attached with the electric heating wire 9, which can make the spiral electric heating wire 9 provide uniform secondary heating effect, further improve the temperature uniformity of the powder, and the model of the electric heating wire 9 is 0Cr21Al 6Nb(A1), which has a wide temperature range, so that the powder can be dried more quickly. And the driving motor 8 is installed on the end face of the first screw rod 41, which can provide a driving source for the first screw rod 41, so that the first screw rod 41 can rotate continuously, and further fix the second screw rod 10 on the other end of the first screw rod 41, and the second screw rod 10 is sleeved with the clamping seat 11, so that the spring pushing piece 12 connected with the clamping seat 11 can rotate synchronously, which is convenient for turning over and pushing away the powder, reduces the accumulation degree of the powder, and the electric heating wire 9 continuously supplies heat to the powder, and the temperature of the powder in different areas is more uniform.

[0033] The side surface of the clamping seat 11 is provided with a spring pushing piece 12; for example, as shown in Figures 3-4 .

[0034] The outer end surface of the spring pushing piece 12 is installed with a turnover plate 13.

[0035] The tank body 1 is provided with a discharge port 14 opposite to the position of the inlet port 2, and the bottom opening of the discharge port 14 is placed with a conveying plate 15.

[0036] By installing the turnover plate 13 on the outer end surface of the spring pushing piece 12, the powder can be turned over and splashed, in this way, the powder is directly laid out, solving the "pyramid temperature" phenomenon, as the turnover plate 13 rotates continuously, the powder is timely spread and laid, the powder with high temperature at the top is pushed down to the bottom and mixed with the powder at the bottom, thereby realizing the uniform mixing of the powder.

[0037] Working principle: first, put the powder at the inlet port 2, then connect the air jet pump 32 with the external power supply, so that the water vapor at the output end of the air jet pump 32 can pass through the air column 31 and input into the inner cavity of the air containing disc 33, to complete the gas drying pre-work of the powder in the tank body 1;

[0038] Then, water vapor escapes again from the surfaces of the round-hole gas distribution groove 34 and the strip-hole gas distribution groove 35, continuously drying the powder. Simultaneously, the drive motor 8 is activated, driving the first screw 41 and the second screw 10 to rotate synchronously. The first screw 41, through its threaded connection, causes the push plate 42 to move along its surface. The side block 43, located on the side of the push plate 42, slides with the straight plate 44, providing directional guidance and balance support for the displacement of the push plate 42. Then, the second screw 10 rotates... Centrifugal force will be generated, which will cause the spring pusher 12 to move along the diameter of the second screw 10. The flip panel 13 will also move in the diameter direction. Since the spring pusher 12 is fixed on one side of the card holder 11, and the card holder 11 is sleeved on the outer surface of the second screw 10, the rotation of the second screw 10 will cause the card holder 11 to rotate synchronously. In addition, the movement states of the spring pusher 12, the flip panel 13 and the card holder 11 are consistent, which further allows the flip panel 13 to rotate, and the powder can be flipped and pushed away, so that the heat brought by the water vapor can be evenly transferred.

[0039] At the same time, the electric heating wire 9 is energized and attached to the outer surface of the tank 1 to heat the inner cavity of the tank 1, thus achieving secondary drying of the powder. Finally, the powder that has undergone secondary drying is discharged through the discharge port 14 and falls into the conveyor plate 15.
