[0035] The working principle and usage process of the present utility model: When sintering production is carried out using a sintering furnace, after the raw materials in the sintering box 201 in the fixed furnace body 1 are sintered, the opening and closing heat insulation plate 203 is driven by the unfolding motor 205 and the linkage transmission box 204 to unfold, separating the opening and closing heat insulation plate 203 from the heat insulation protective sleeve 202. At this time, the heat conducts along the sintering box 201 into the fixed furnace body 1. At this time, the fixed blower 214 and the outer exhaust pipe rack 212 extract the high-temperature hot air flowing in the fixed furnace body 1. The hot air flows along the outer exhaust pipe rack 212 and enters the heating storage barrel 213 to preheat the raw materials in the heating storage barrel 213. When the outer exhaust pipe rack 212 extracts the hot air in the fixed furnace body 1, the air at the position of the cooling double-layer barrel 209 is extracted through the extraction fixed cylinder 208, the linkage pipe rack 207 and the air inlet fixed cylinder 206, so as to stabilize the internal air, realize the preliminary cooling treatment of the sintered material in the sintering box 201, and transfer the heat to the raw material position to realize heat recovery treatment;

[0036] After cooling and forming, the cooling double-layer barrel 209 is driven by the processing motor 302 to rotate along the linkage fixing frame 301. At this time, after the lifting and alignment are completed, the movable electric push rod 305 drives the closing insertion plate 306 to move downward, opening the cooling double-layer barrel 209 and the fixed furnace body 1. Then, the inlet and outlet electric push rod 303 drives the fixed furnace body 1 to move to the side end of the cooling double-layer barrel 209. At this time, the sintered product moving belt in the sintering box 201 drops into the inner side of the cooling double-layer barrel 209. After discharging is completed, the processing motor 302 drives the cooling double-layer barrel 209 to reset. At this time, the clamping motor 307 drives the clamping fixing plate 308 to rotate, opening the space between the heating storage barrel 213 and the fixed furnace body 1. Then, the inlet and outlet electric push rod 303 drives the heating storage barrel 213 to fit to the side end of the fixed furnace body 1, placing the internal raw materials inside the sintering box 201, realizing continuous feeding processing. Through multiple linkage components, continuous material replacement operation is realized, and the position of the product can be changed during sintering and cooling, realizing uniform heat treatment of the product and accelerating the processing speed;

[0037] When the sintered product is placed inside the cooling double-layer barrel 209, air is extracted and heat is dissipated through the fixed blower 214, the extraction fixed cylinder 208 and the linkage pipe rack 207, and is discharged into the inner side of the fixed furnace body 1 through the air inlet fixed cylinder 206. Through continuous heat conduction, the side end of the sintering box 201 is heated, cooperating with electric heating to improve the heating speed, and the heat is recycled again. For some products that need to be quickly cooled, air is introduced through the air holes 211, cooperating with the porous heat exchanger 210 for condensation treatment, accelerating the cooling speed and improving the forming speed.
