[0019] The feed pipe 101 is provided with a valve inside, which may be a solenoid valve. The specific valve type may be selected according to actual conditions, and is used to control the introduction of slag into the furnace body 1;

[0020] The heat exchange structure 31 includes a liquid storage tank 311 fixedly connected to one side of the escalator 2, the liquid storage tank 311 is filled with heat transfer oil, a pump body 312 is arranged inside the liquid storage tank 311, one side of the liquid storage tank 311 is connected with a return pipe 316, a heat conduction shell 313 is fixedly connected to the surface of the furnace body 1, a heat absorption cavity is opened inside the heat conduction shell 313, and the heat conduction shell 313 is an aluminum metal material component;

[0021] A heat exchange tube 314 is arranged inside the heat absorption chamber. The heat exchange tube 314 is arranged in a spiral shape. One end of the heat exchange tube 314 passes through the heat-conducting shell 313 and is connected to the liquid outlet end of the pump body 312. The other end of the heat exchange tube 314 is connected to the outlet pipe 315. The other end of the outlet pipe 315 passes through the heat-conducting shell 313.

[0022] The heat emitted outward during the operation of the furnace body 1 can be absorbed by the heat-conducting shell 313, and this part of the heat is used to heat the heat exchange tube 314 inside the heat absorption chamber. The heat transfer oil is introduced into the heat exchange tube 314 through the pump body 312. In this process, the heat exchange tube 314 can absorb the heat adsorbed inside the heat absorption chamber, and use the flow of the heat transfer oil to apply this part of the heat to the preheating structure 32. The spirally arranged heat exchange tube 314 can effectively increase the contact area with the heat absorption chamber, thereby improving the heat absorption effect, effectively utilizing this part of the waste heat, and improving resource utilization.

[0023] The preheating structure 32 includes a mounting box 321 fixedly connected to the inner wall of the material storage box 102, a ventilation slot 326 connected to the material storage box 102 is provided on the surface of the mounting box 321, a heat conducting pipe 322 is provided inside the mounting box 321, and the heat conducting pipe 322 is arranged in a serpentine line, one end of the heat conducting pipe 322 passes through the material storage box 102 and is connected to the outlet pipe 315, and the other end of the heat conducting pipe 322 passes through the material storage box 102 and is connected to the return pipe 316;

[0024] The heat transfer oil after absorbing heat is injected into the interior of the heat transfer pipe 322 through the heat exchange pipe 314. In this process, the heat can be dissipated into the interior of the storage box 102 through the ventilation slots 326, which is used to preheat the slag stored in the storage box 102, so that the preheated slag can be introduced into the interior of the furnace body 1 for subsequent processing, thereby improving the efficiency of subsequent processing.

[0028] The slag in the storage box 102 can be quickly introduced into the furnace body 1 through the feed pipe 101 for processing through the material guiding area.

[0029] Working principle: the slag to be processed is stored in the storage box 102 and introduced into the furnace body 1 through the feed pipe 101, and processed by the furnace body 1. During the processing, the pump body 312 is started to inject the heat transfer oil into the heat exchange tube 314, and the heat dissipated during the operation of the furnace body 1 is absorbed by the heat transfer shell 313. During the flow of the heat transfer oil inside the heat exchange tube 314, the heat adsorbed in the heat absorption cavity can be absorbed, and the flow of the heat transfer oil is used to apply this part of the heat to the preheating structure 32. The slag stored in the storage box 102 is preheated by the preheating structure 32, and the waste heat dissipated in the process of slag processing by the furnace body 1 is effectively utilized, thereby improving resource utilization. After the preheated slag enters the furnace body 1, the processing time is reduced, the slag processing efficiency is improved, and the heat transfer oil is returned to the internal storage of the liquid storage tank 311 through the return pipe 316 to form a heat transfer oil circulation.
