[0001] The utility model relates to the technical field of carbonization furnaces, and more specifically, to a high-temperature carbonization furnace capable of continuous heating. Background Art
[0002] High-temperature carbonization furnaces are mainly used to convert solid substances into carbides. Through heat treatment in a high-temperature environment, the carbon on the surface of the substance gasifies to form carbon compounds, thereby improving the hardness, strength, and service life of the material.
[0003] In the existing published literature, the patent with the patent publication number CN217377783U discloses a high-temperature carbonization furnace. In this carbonization furnace, cooling water circulates in the water-cooling pipe for one circle and then is transported to the water tower through the water inlet pipe. In this way, the cooling water forms a cycle in the water-cooling pipe. During the circulation of the cooling water, the heat of the furnace wall will be continuously taken away, thereby cooling the furnace wall, and solving the problem in the prior art that the device cannot effectively cool the carbon after carbonization is completed, resulting in time consumption and low carbon output efficiency. However, the following problems still exist in the use of this carbonization furnace;
[0004] During the use of the carbonization furnace, carbonization needs to be achieved through heating. However, a large amount of high-temperature waste gas is generated during the heating process. It is difficult for the high-temperature waste gas to contact the incoming carbonization raw materials for preheating, and it is difficult to perform secondary continuous heating again after preheating, and it is difficult to fully utilize the waste gas heat energy to continuously heat the carbonization raw materials. This results in poor energy conservation for continuous heating. Therefore, a high-temperature carbonization furnace capable of continuous heating is provided. Summary of the Utility Model

By utilizing the waste gas heat energy, continuous preheating is realized, saving carbonization heat energy and having better energy-saving performance. The specific structural setting of the preheating mechanism is as follows.
[0024] In this embodiment, as shown in the appendix Figures 1-4 As shown in the figure, the preheating box 2 is fixedly communicated with the top end of the furnace body 1, and the partition plate 3 is slidably inserted into the inner wall of the preheating box 2. It is characterized in that: a preheating mechanism is provided on one side of the partition plate 3; the preheating mechanism includes a push block 5 fixedly arranged on one side of the partition plate 3, and a plurality of air-permeable holes 4 are opened in the inner wall of the partition plate 3. An electric cylinder 6 is fixedly installed on one side of the push block 5, and the electric cylinder 6 is fixedly connected with the preheating box 2; the top end of the preheating box 2 is slidably connected with a cover plate 7. A pushing block 8 is welded on one side of the cover plate 7, and a linkage electric cylinder 9 is fixedly installed on the top end of the pushing block 8. The plurality of air-permeable holes 4 are arranged at equal intervals in sequence from front to back. The cross-sectional shape of the air-permeable hole 4 is set as a rectangle. A support frame 10 is installed on one side of the linkage electric cylinder 9, and both the linkage electric cylinder 9 and the preheating box 2 are fixedly connected with the support frame 10; the vertical cross-sectional shape of the support frame 10 is T-shaped.
[0025] In this embodiment, as shown in the appendix Figures 1-5 As shown in the figure, an exhaust hole 11 is opened at the top end of the cover plate 7, and the cross-sectional shape of the exhaust hole 11 is set as a circle, so that the preheated waste gas can be discharged upward along the exhaust hole 11, facilitating the external discharge of waste gas in the later stage. The inner wall of the furnace body 1 is fixedly installed with a carbonization partition plate 12, and a resistance heater 13 fixedly connected with the furnace body 1 is arranged below the carbonization partition plate 12.

[0030] When used according to the above structure, when the partition plate 3 moves out of the preheating box 2, the partition plate 3 drives the socket slider 16 to move. The socket slider 16 slides along the outer wall of the guiding column 17. At the same time, the partition plate 3 drives the sliding ring 18 to move.
