[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-4 The first embodiment shown is a high-temperature reburning electric furnace for refractory material production, comprising an electric furnace body 1, the electric furnace body 1 being connected to a processing part for refractory material production, the processing part comprising: an adjusting part 2, mounted on the electric furnace body 1 for protecting and cooling the feed end, the adjusting part 2 comprising a door sealing assembly 21, the door sealing assembly 21 comprising a connecting frame 211 rotatably connected to the left side of the electric furnace body 1, a cover plate 212 fixedly connected to the right side of the connecting frame 211 and engaged with the feed end on the front side of the electric furnace body 1; a cylinder assembly 3, mounted on the right side of the electric furnace body 1, a locking frame 4 fixedly connected to the left extended end of the cylinder assembly 3 for locking the cover plate 212;

[0024] A protective member 5 is installed on the right side of the electric furnace body 1 for furnace gas treatment. The protective member 5 includes an air pump 51 installed on the right side of the electric furnace body 1. A one-way valve 52 is installed at the exhaust end of the air pump 51. An injection pipe 53 is installed on the lower side of the one-way valve 52. An absorption shell 54 with a built-in treatment liquid is fixedly connected to the bottom of the injection pipe 53. A bifurcated pipe 55 is installed at the exhaust end of the air pump 51. An air filter plate 56 is fixedly connected to the upper and lower sides of the electric furnace body 1 near the cover plate 212. Both sets of air filter plates 56 are fixedly connected to the bifurcated pipe 55. The conduit 23 and the return pipe 26 are corrugated pipes. Heat sinks are installed on the front and rear sides of the liquid storage tank 25. A handle is installed on the front side of the cover plate 212.

[0025] The inner side of the locking frame 4 is provided with a locking groove which is slidably connected to the right end of the cover plate 212. The sealing door assembly 21 also includes scrapers 213 installed on the upper and lower sides of the cover plate 212. Two sets of air extraction filter plates 56 are provided with a plurality of air extraction filter holes near the end of the cover plate 212. The inner ends of the air extraction filter plates 56 are hollow and are respectively connected to the bifurcated pipe 55 and the air extraction filter holes. A pressure relief valve is installed at the upper end of the rear side of the absorption shell 54, a discharge valve is installed at the lower end of the rear side of the absorption shell 54, and a feeding pipe is provided on the upper side of the absorption shell 54. 2. The injection pipe 53, the absorption shell 54 with the built-in treatment liquid, the bifurcated pipe 55, and the exhaust filter plate 56 cooperate with each other. During the opening process of the electric furnace body 1, the exhaust gas and odor generated by the heating of the refractory material are extracted and absorbed by the exhaust gas and treatment liquid at the end of the gap between the electric furnace body 1 and the cover plate 212. The one-way valve 52 prevents the treatment liquid from flowing back, and the exhaust filter holes in the exhaust filter plate 56 filter impurities in the gas. During the rotation of the cover plate 212, the scraper 213 scrapes and cleans the exhaust filter plate 56.

[0026] like Figure 1-4 The second embodiment shown is mainly different from the first embodiment in that:

[0027] The regulating member 2 also includes a liquid pump 22 installed at the left end of the outer side of the electric furnace main body 1. The upper discharge end of the liquid pump 22 is equipped with a conduit 23 fixedly connected to the connecting frame 211. The liquid extraction end of the liquid pump 22 is fixedly connected to a liquid extraction pipe 24. The bottom of the liquid extraction pipe 24 is fixedly connected to a liquid storage tank 25 with a built-in coolant. A return pipe 26 fixedly connected to the liquid storage tank 25 is installed on the lower side of the connecting frame 211. A cooling tank is provided in the cover plate 212, and the cooling tank is connected to the conduit 23 and the return pipe 26 respectively through the connecting frame 211. Before the electric furnace main body 1 is opened, the liquid pump 22, the conduit 23, the liquid extraction pipe 24, the liquid storage tank 25 with a built-in coolant, and the return pipe 26 cooperate with each other to absorb heat from the cover plate 212 and the feeding end of the electric furnace main body 1 to reduce safety hazards.

[0028] At the same time, the contents not described in detail in this specification belong to the existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0029] During use, the user drives the locking frame 4 to separate from the right side of the cover plate 212 through the cylinder assembly 3, and drives the cover plate 212 to rotate through the connecting frame 211, so that the front side of the electric furnace body 1 is opened, and the refractory material to be processed is placed inside the electric furnace body 1, so that each link is reset, and the electric furnace body 1 is started. The electric furnace body 1 performs high-temperature reburning treatment on the refractory material. After the high-temperature reburning is completed, the electric furnace body 1 is closed and the liquid pump 22 is started. The liquid pump 22 extracts the coolant in the liquid storage tank 25 through the liquid extraction pipe 24, and then the coolant is introduced into the groove in the cover plate 212 through the guide tube 23 and the connecting frame 211. The coolant absorbs heat from the cover plate 212 and the front side of the electric furnace body 1 through heat exchange;

[0030] After the electric furnace body 1 is cooled to a suitable temperature near the cover plate 212 end, the locking frame 4 is separated from the cover plate 212, and the vacuum pump 51 is turned on. The vacuum pump 51 exhausts the edge of the cover plate 212 through the bifurcated pipe 55 and the vacuum filter plate 56. The gas extracted by the vacuum filter plate 56 is introduced into the absorption shell 54 through the one-way valve 52 and the injection pipe 53. The cover plate 212 is slowly opened, and the exhaust gas generated by the heating of the refractory material is sucked into the vacuum filter plate 56. The treatment liquid in the absorption shell 54 absorbs the exhaust gas. Finally, the cover plate 212 is completely opened and the reburned refractory material is taken away. Since the electric furnace body 1 is a prior art, its specific working principle and internal structure are not described in detail. The scraper 213 scrapes the exhaust end of the vacuum filter plate 56 when it rotates with the cover plate 212 to prevent blockage.
