They are essential basic materials to ensure the production operation and technological development of the above industries and play an irreplaceable and important role in the development of high-temperature industrial production. During the processing of refractories, a heat treatment kiln is required for high-temperature roasting to physically and chemically change the properties of the refractories.

[0003] The invention patent with the publication number CN108571886A discloses a refractory high-temperature furnace. By fixedly connecting sliders to the bottoms of both sides of the movable frame, and the side of the slider is slidably connected to the inner wall of the rectangular box. Filter holes are opened at the bottom of the inner wall of the movable frame. An activated carbon adsorption plate is fixedly connected between the two sides of the bottom of the inner wall of the rectangular box. Sealing gaskets are fixedly connected to both sides of the top of the inner wall of the rectangular box. An exhaust pipe is communicated with the bottom of one side of the rectangular box. Through the coordinated setting of the intake pipe, the air delivery pipe and the air purifier, the first-step dust filtration of the harmful gases generated in the high-temperature furnace can be realized, preventing the dust from spreading into the air and causing harm to human health, laying a foundation for the subsequent treatment of harmful gases, and creating a good working environment for the staff. Also, a rotating device is fixedly connected to one end of the output shaft of the motor. The rotating device includes a disc, the top of the disc is fixedly connected to one end of the output shaft of the motor, a crescent plate is fixedly connected to the bottom of the disc, a cylindrical block is fixedly connected to the surface of the disc and close to one side of the crescent plate. A movable rod is rotatably connected to the top of the inner wall of the rectangular frame and on one side of the motor through a bearing. The bottom end of the movable rod sequentially penetrates through the rectangular frame and the rectangular box and extends into the interior of the rectangular box. A rotating blade is fixedly connected to the end of the movable rod extending into the interior of the rectangular box. A rotating plate is fixedly connected to the surface of the movable rod and within the rectangular frame. An arc groove adapted to the crescent plate is opened on the surface of the rotating plate.

In cooperation with the socket on the surface of the attaching plate 54, under the movement interference, the connecting seat 55 will start to slowly move outward, and the scraper 56 on its surface will gradually approach the inner wall of the calcination kiln 7 until it presses against the impurity layer formed by crushing and molding. At the same time, the connecting rod 57 will conduct the absorbed heat. During the process of telescopic movement in cooperation with the sleeve 12 fittings, when it retracts, it will heat up the water in the metal tube 38 to achieve the purpose of waste heat recovery. During the roasting production process of refractory materials, in order to make the scraper 56 close to the inner wall surface of the calcination kiln 7 for thorough cleaning, the user can control the second motor 16 to operate. During its operation, the first pulley 17 and the connecting arm 19 located at the output end will move simultaneously and separately drive other fittings. Among them, the first pulley 17 will drive the connecting shaft 21 to rotate, and then the straight rod 22 and the arc-shaped dial 23 will start to rotate accordingly. During this process, the straight rod 22 will cooperate with the guiding groove 30, and the arc-shaped dial 23 will cooperate with the notch 29 to make the connecting cylinder 28 rotate correspondingly through movement interference. The docking rod 26 will rotate on the surface of the connecting plate 25 in cooperation with the convex strip 27 and the slotted groove 32.
