The operator places multiple materials in the feed box 5 in turn, and the materials slide downward in the feed box 5 in turn to the preheating box 4 for preheating, and the preheated materials are transported to the furnace body 2, and the materials are heated to an appropriate temperature by the installed heating coil 3, and the heated materials are transported to the recovery box 12, and the heat emitted by the materials is recovered by the recovery box 12, thereby energy-saving treatment is performed on the device.

[0022] An electric push rod 8 is fixedly connected to the side wall of the preheating box 4, and the output end of the electric push rod 8 is slidably connected to the side wall of the preheating box 4. The material sliding into the preheating box 4 is pushed by the electric push rod 8. While the electric push rod 8 is pushing, the side wall of the output end of the electric push rod 8 blocks the opening at the lower end of the feed box 5 to prevent the material inside the feed box 5 from sliding into the preheating box 4, causing blockage inside the preheating box 4.

[0023] A cavity 6 is provided inside the preheating box 4. A plurality of holes 7 are provided on the inner walls around the preheating box 4. The holes 7 are connected to the cavity 6. A hot air flow flows inside the cavity 6 and is discharged through the plurality of holes 7, thereby preheating the material.

[0024] A chute 9 is provided at both upper and lower ends of the preheating box 4, a baffle 10 is slidably connected inside the chute 9, a spring 11 is fixedly connected between the end of the baffle 10 and the inner wall of the chute 9, the inner wall of the baffle 10 is inclined, the inside of the preheating box 4 is blocked by the baffle 10, so that the hot air flow flows inside the preheating box 4 to preheat the material, and the preheated material is pushed into the furnace body 2 for heating by the electric push rod 8. In the process of the material entering the furnace body 2 from the preheating box 4, the end of the material contacts the inclined end of the baffle 10, so that the baffle 10 automatically shrinks to the inside of the chute 9.

[0025] A cavity 13 is provided inside the upper end of the recovery box 12 , and a plurality of through holes 14 are provided at the top of the recovery box 12 .

[0027] In the utility model, the operator places multiple materials in the feed box 5 in sequence, and the materials slide downward inside the feed box 5 to the inside of the preheating box 4. The electric push rod 8 pushes the materials that slide into the preheating box 4 to the positions of the multiple holes 7, and then the hot air flow inside the cavity 6 is discharged through the multiple holes 7, thereby preheating the materials.

[0028] The preheated material is pushed into the furnace body 2 for heating by the electric push rod 8.

After the material is pushed into the furnace body 2, the output end of the electric push rod 8 retracts into the preheating box 4. When the baffle 10 is no longer in contact with the material and the output end of the electric push rod 8, the elasticity of the spring 11 causes the baffle 10 to automatically slide out of the chute 9.

[0029] After the material is heated, the material inside the furnace body 2 is pushed into the recovery box 12 by the electric push rod 8, and the residual heat after the material is heated flows into the cavity 13 through multiple through holes 14, and then the hot air flow collected in the cavity 13 is transported to the inside of the cavity 6 through the air pump 15, connecting pipe 1 16 and connecting pipe 2 17.
