[0029] Such as Figures 1 to 5As shown in the figure, a device for recycling the residual heat of a high-temperature Soxhlet furnace body includes: a heating furnace 1, with a heating tank 101 opened on one side of the heating furnace 1, and a fixed frame 103 is arranged inside the heating tank 101; a heat exchange component, arranged inside the heating furnace 1, used for absorbing the temperature of the lead liquid. The heat exchange component includes a fixing part and a guiding part 6. The fixing part is arranged inside the heating furnace 1, and the guiding part 6 is arranged outside the fixing part. The fixing part cooperates with the guiding part 6 to heat the air; a drying component 4, arranged on one side of the heating furnace 1, used for drying the steel wire; a conveying component, arranged outside the heating furnace 1, used to connect the heating furnace 1 and the drying component 4. Specifically, when heat-treating the metal, first, the residual heat of the lead liquid is absorbed through the cooperation of the fixing part and the guiding part 6, so that the absorbed residual heat enters the drying component 4 through the guidance of the conveying component, thereby quickly drying the wet metal. The heating furnace 1 is a Soxhlet metal heat treatment furnace, which can perform heat treatment operations on the processed metal during use, thereby improving the performance of the metal during use. The heating tank 101 is filled with lead liquid for heating the metal. During the use of the heating furnace 1, a top cover is also provided on the top of the heating tank 101 to prevent foreign objects from falling into the heating tank 101 during use. The heating furnace 1 is a prior art and will not be explained in detail here.

[0030] As Figures 1 to 5 shown, a communicating pipe 102 and a first blower 2 are respectively arranged outside the heating furnace 1, and the communicating pipe 102 is communicated with the heating tank 101. Specifically, the fixing part divides the space inside the heating tank 101, so that the guiding part 6 can be separated from the heating liquid during use. During use, a heat-conducting liquid can be filled into the space at the bottom of the fixing part through the communicating pipe 102, thereby increasing the heating area when the guiding part 6 is used and improving the heating speed of the air inside the guiding part 6.

[0031] As Figures 1 to 5 shown, the fixing part includes a heat-conducting plate 601, the heat-conducting plate 601 is arranged inside the fixed frame 103, a connecting groove 606 is opened on one side of the heat-conducting plate 601 relative to the bottom of the heating tank 101, and a plurality of heating plates 604 are arranged on one side of the heat-conducting plate 601 relative to the bottom of the heating tank 101. A groove 607 is opened inside the heating plate 604, and the groove 607 penetrates through one side of the heating plate 604. Specifically, the heat-conducting plate 601 is connected to the heating furnace 1 through the fixed frame 103, so as to divide the space inside the heating tank 101 and prevent the lead liquid inside the heating tank 101 from flowing to the bottom of the heat-conducting plate 601 during use. The heat-conducting plate 601 is made of a metal material with good heat conduction, thereby improving the temperature transfer effect during the use of the guiding part 6.

[0032] As Figures 1 to 5As shown, the guiding member 6 includes a plurality of heating tubes 602. The heating tubes 602 are arranged inside the connecting groove 606, and the heating tubes 602 have the same shape as the connecting groove 606. A flow guiding plate 603 is provided inside the heating tubes 602, and a plurality of grid plates 605 are provided outside the heating tubes 602. One end of the heating tube 602 is communicated with the first blower 2. Specifically, when absorbing the waste heat inside the lead liquid, first, the first blower 2 injects air into the heating tubes 602, so that the air flows along the heating tubes 602. During the flowing process, the flow guiding plate 603 guides to increase the residence time of the air inside the heating tubes 602, ensuring that the air inside the heating tubes 602 can fully absorb the waste heat. The heating tubes 602 can be in a snake shape or a spiral shape, and the cross-section of the heating tubes 602 can be square tubular or rectangular tubular, thereby increasing the contact area between the heating tubes 602 and the heat conducting plate 601 while extending the residence time of the air inside the heating tubes 602. The heating tubes 602 are made of a material with good thermal conductivity, and the surface of the heating tubes 602 is closely attached to the inner wall of the connecting groove 606 to prevent a gap between the heating tubes 602 and the connecting groove 606 from causing a reduction in the heat conduction efficiency. The heating plate 604 can heat the heat conducting liquid injected at the bottom of the heat conducting plate 601. By opening the groove 607, the contact area between the heating plate 604 and the heat conducting liquid is increased. The heating plate 604 and the heat conducting plate 601 are made of the same material to ensure that heat can be quickly transferred during use. The grid plates 605 outside the heating tubes 602 are in contact with the heat conducting liquid, thereby increasing the contact area between the heat conducting liquid and the heating tubes 602, further ensuring the heating effect of the air inside the heating tubes 602. Through the cooperation of the heat conducting plate 601 and the heat conducting liquid, the heating area of the heating tubes 602 is further increased during use, thereby shortening the air heating time while increasing the air flow speed.

[0033] As Figures 1 to 5 shown, the conveying assembly includes a second blower 3 and a plurality of diversion tubes 5. The diversion tubes 5 are connected to the other end of the heating tubes 602. A conduction tube 501 is connected to the outside of the diversion tubes 5. An air inlet pipe 301 and an air outlet pipe 302 are respectively provided outside the second blower 3. The air inlet pipe 301 is connected to the conduction tube 501. Specifically, the diversion tubes 5 cooperate with the conduction tube 501 to guide the heated air, so that the heated air can enter the second blower 3 through the air inlet pipe 301 for further blowing, thereby increasing the air flow speed. The blown air enters the drying assembly 4 through the guidance of the air outlet pipe 302 to achieve rapid drying of the metal. The number of the second blowers 3 is selected according to the actual distance between the heating furnace 1 and the drying assembly 4, so as to avoid the situation of reduced air flow speed when the distance between the heating furnace 1 and the drying assembly 4 is large.

[0034] As Figures 1 to 5As shown, the drying component 4 includes a fixed box 401. A shunt pipe 403 is provided outside the fixed box 401. The fixed box 401 is communicated with the shunt pipe 403, and the shunt pipe 403 is connected to the air outlet pipe 302. A plurality of heaters 402 are further provided inside the fixed box 401. Specifically, the shunt pipe 403 can evenly introduce the air blown out by the air outlet pipe 302 into the drying component 4, thereby realizing the drying of the metal. When in use, the heaters 402 can assist the hot air to further increase the temperature inside the fixed box 401, ensuring the effect of metal drying.
