[0020] In this process, by driving the motor 16, the second pulley 17 is driven to rotate, the second pulley 17 drives the toothed belt 18 to rotate, the toothed belt 18 drives the first pulley 15 to rotate, the first pulley 15 drives the rotating ring 7 to rotate, the rotating ring 7 drives the protrusion 9 connected thereto to rotate, the protrusion 9 drives the sleeve 6 to rotate, the sleeve 6 drives the tank body 13 connected thereto to rotate, and the tank body 13 drives the inner tank 28 to rotate 360° in the vertical direction, so that the material in the inner tank 28 is turned over;

The sine current is switched between positive and negative half cycles. At the moment of switching between positive and negative half cycles, the sine current disappears. The frequency of switching between positive and negative half cycles is very high, so the frequency of the magnetic field generated by the pulse electromagnet 10 is also very high. The magnetic force generated by the pulse electromagnet 10 is also instantaneous. At the moment of generating the magnetic force, the pulse electromagnet 10 attracts the iron sheet 11 to move towards the pulse electromagnet 10.

[0024] The working principle is that in the process of vacuum drying of the existing double-cone dryer, the wet material is easy to accumulate together, which causes uneven heating of the material and low drying efficiency. The material is poured into the inner tank 28 from the feeding pipe 24, and then hot water is used to heat the inner tank 28 for indirect heating of the material, and the inner tank 28 is vacuumized.

The sinusoidal current is switched between positive and negative half cycles. At the moment of switching between positive and negative half cycles, the sinusoidal current disappears. The frequency of switching between positive and negative half cycles is very high, so the frequency of the magnetic field generated by the pulse electromagnet 10 is also very high. The magnetic force generated by the pulse electromagnet 10 is instantaneous. The pulse electromagnet 10 attracts the iron sheet 11 to move towards the pulse electromagnet 10 at the moment of generating the magnetic force.

The tank body 13 drives the inner tank 28 to move horizontally to the left. The inner tank 28 drives the material inside to move horizontally to the left. Because the switching frequency of the magnetic field generation and disappearance is extremely high, the tank body 13 generates high-frequency vibration, which realizes high-frequency vibration of the material in the inner tank 28 in the horizontal direction. This structure can make the material turn over in the vertical direction and also make the material vibrate in the horizontal direction, so that the accumulated material is quickly dispersed, the material is uniformly heated, and the drying efficiency is improved.095MPa, the vacuum filter 22 can prevent the powder from entering into the vacuum pipe 21, while the tank body 13 is overturned and high-frequency vibrated, the convenient drying of the material is realized, and the convenience of the material drying is improved.
