For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0027] Reference Figures 1 to 3The embodiment of the present application provides a tunnel furnace structure, comprising: a furnace body 100 for sintering materials, the furnace body 100 is provided with a feeding port 110 and a discharging port 120, the top of the feeding port 110 and the discharging port 120 is provided with a fixing block 130; a conveying mechanism 200 is arranged in the furnace body 100, and the conveying mechanism 200 is used for conveying materials; a protection mechanism comprises a protection plate 310, the protection plate 310 is coated with high-temperature resistant paint, the protection plate 310 is arranged on the feeding port 110 and the discharging port 120, the protection plate 310 comprises a main plate 320, a first side plate 330 and a second side plate 340, the first side plate 330 and the second side plate 340 are arranged on the two sides of the main plate 320 respectively, the main plate 320 is detachably connected with the fixing block 130, so that the first side plate 330 is located inside the furnace body 100, and the second side plate 340 is located outside the furnace body 100.

[0028] By arranging the protection plate 310 at the feeding port 110 and the discharging port 120, the high-temperature resistant paint falling at the feeding port 110 and the discharging port 120 can be blocked, so that the quality of the materials is guaranteed; by detachably connecting the main plate 320 and the fixing block 130, the protection plate 310 can be taken off from the furnace body 100, so that the high-temperature resistant paint on the protection plate 310 can be coated regularly, the operation is more convenient, and the working efficiency is improved.

[0029] Specifically, the main plate 320 is provided with a downward bending portion 350, and the bending portion 350 is connected with the fixing block 130 through bolts. By arranging the bending portion 350, the connection between the protection plate 310 and the furnace body 100 is realized, the structure is simple, and the operation is convenient. The height of the second side plate 340 is higher than that of the first side plate 330. Hot gas in the furnace body 100 can overflow from the feeding port 110 and the discharging port 120, at this time, the hot gas contacts the outer wall of the furnace body 100 with low temperature to form moisture, which can cause more serious paint falling, at this time, by arranging the second side plate 340 to be higher in height, the falling paint can be better blocked, the protection efficiency is further improved, and the quality of the materials is improved.

[0030] Reference Figure 1 And Figure 2 Further, the protection mechanism further comprises a protection cover 360, the protection cover 360 is arranged at one end of the discharging port 120, and the protection cover 360 is arranged above the conveying mechanism 200. After the materials are sintered, the materials are output from the discharging port 120, at this time, the temperature of the materials is high, by arranging the protection cover 360, the risk that a worker is scalded by accidentally touching the high-temperature materials can be avoided, and the safety of the worker is improved. The two sides of the protection cover 360 are provided with handles 370. By the handles 370, the disassembly and assembly of the protection cover 360 can be realized conveniently, the labor intensity is reduced, and the working efficiency is improved.

[0031] It is conceived that the furnace body 100 is provided with a heating element, which is located at the bottom of the furnace body 100. Further, the top of the furnace body 100 is provided with an exhaust port, and an exhaust cover 140 is arranged above the exhaust port, and an exhaust fan 160 is connected to the exhaust cover 140 through an exhaust pipe 150. The exhaust fan 160 works to form a negative pressure in the exhaust pipe 150, so that the gas in the furnace body 100 is sucked away through the exhaust cover 140, so as to accelerate the heat flow in the furnace body 100 and improve the sintering efficiency. It is easy to understand that a temperature sensor is arranged in the furnace body 100, which is connected with the heating element, so as to keep the temperature in the furnace body 100 within a set range and improve the sintering quality.

[0032] With reference to Figure 1 and Figure 2 In the embodiment, the conveying mode of the conveying mechanism 200 is a circulating conveying mode, so as to reduce the occupied space and facilitate the feeding and discharging of the materials. The conveying mechanism 200 is provided with a turning assembly 210, which comprises a push plate 220 and a driving element. The push plate 220 is slidingly arranged on the conveying mechanism 200, and the driving element is connected with the push plate 220. The driving element drives the push plate 220 to move, so as to push the materials to turn. The structure is simple and the operation is convenient. Further, the turning assembly 210 further comprises a trigger switch 230, which is connected with the driving element. When the materials reach the specified position, the trigger switch 230 is triggered, and at this time, the driving element drives the push plate 220 to move, so as to ensure the stability and reliability of the work.
