[0031] Working principle: When work is required, the particles to be melted are poured into the interior of the melting and crushing shell 1, and the particles fall onto the screen plate 8. By controlling the starting motor 201, the output shaft of the motor 201 rotates to drive the rotating rod 1 202 to rotate, and the rotating rod 1 202 rotates to drive a group of bevel gears 203 to rotate. The two groups of bevel gears 203 are meshed, and the rotation of the other group of bevel gears 203 drives the rotating rod 2 204 to rotate. The rotation of the rotating rod 204 drives the crushing blade 3 to rotate. The rotation of the crushing blade 3 can crush the particles. At the same time, the rotation of the rotating rod 1 202 drives the fan blade 4 to rotate. The rotation of the fan blade 4 generates wind force to blow the dust on the crushed particles to one side inner wall of the melting and crushing shell 1. The wind communicates the dust through the filter hole opened in the air inlet hopper 901 into the interior of the connecting pipe 1 902, and enters the connecting pipe 2 903 through the connecting pipe 1 902. Inside, two groups of screens 904 are arranged inside the connecting pipe 2 903 to separate the connecting pipe 2 903 into two cavities. Dust enters the two cavities through the screens 904 and is absorbed by the activated carbon 10 filled in the cavity. When the connecting pipe 2 903 needs to be disassembled, the connecting pipe 2 903 and the connecting pipe 1 902 are separated by rotation. The crushed particles after cleaning enter the bottom of the inner side of the melting and crushing shell 1 through the screen plate 8. The screen plate 8 screens out the larger crushed particles and starts the electric heating plate 14. The electric heating plate 14 generates high temperature to melt the crushed particles at the bottom of the melting and crushing shell 1. At this time, by controlling the starting motor 2 11, the output shaft of the motor 2 11 rotates to drive the rotating rod 3 12 to rotate, and the rotating rod 3 12 rotates to drive the spiral blade 13 to rotate. The rotation of the spiral blade 13 drives the melted particles to move toward one side of the melting and crushing shell 1 and is extruded through the extrusion shell 15.
