It is widely used for the lining protection of high-temperature industrial kilns. In order to avoid cracking, insufficient strength and unstable performance of high-alumina castable for kilns, it is necessary to bake it.

The rotation of the output shaft of the motor 71 drives the drive shaft 72 to rotate. The rotation of the driven pulley 78 drives the rotating column 12 to rotate. The rotation of the rotating column 12 drives the stirring frame to rotate, and at the same time drives the fixed helical gear 84 to rotate.

[0024] The grinding and screening mechanism 8 includes a rotating drum 81, a rotating cylinder 82, grinding rollers 83, and an arc-shaped filter plate 86. The rotating drum 81 is rotatably connected to the upper end of the top chamber 3, and the rotating cylinder 82 is fixedly connected to the lower end of the rotating drum 81. The central axes of the rotating column 12, the rotating drum 81, the rotating cylinder 82, and the arc-shaped filter plate 86 coincide. The outer arc surface of the rotating cylinder 82 is rotatably connected to evenly distributed grinding rollers 83. The arc-shaped filter plate 86 is fixedly connected inside the top chamber 3. The arc-shaped filter plate 86 is a conical plate with evenly distributed filter holes inside. All three grinding rollers 83 are installed in conjunction with the arc-shaped filter plate 86, and the inclination of the grinding rollers 83 is the same as the cone angle of the arc-shaped filter plate 86. The grinding and screening mechanism 8 also includes a fixed helical gear 84, a driven helical gear 85, and a driven gear 87. The fixed helical gear 84 is fixedly connected to the upper end of the outer surface of the rotating column 12 and is located inside the rotating cylinder 82.

The transmission shaft 76 rotates, driving the transmission gear to rotate. The transmission gear rotates, driving the driven gear 87 to rotate. The driven gear 87 rotates, driving the drum 81 to rotate. The drum 81 rotates, driving the rotating drum 82 to rotate. The rotating drum 82 rotates, driving the three grinding rollers 83 to rotate around the central axis of the drum 81. The driven helical gears 85 rotate under the meshing action of the fixed helical gears 84, thereby causing the grinding rollers 83 to rotate on their own axis during the revolution. Under the support of the arc-shaped filter plate 86, the high-alumina castable for the kiln is ground. The ground high-alumina castable for the kiln enters the interior of the baking chamber 2 through the arc-shaped filter plate 86.

[0025] Wherein: a heating chamber 9 is fixedly connected to the middle of the support frame 1, the interior of the heating chamber 9 is rotatably connected to the outer surface of the baking chamber 2, and a heater 10 is evenly distributed inside the heating chamber 9. The input end of the heater 10 is electrically connected to the output end of the controller 13. The controller 13 realizes the operation of the heater 10 to heat the air inside the baking chamber 2.

[0026] The bottom chamber 4 is equipped with a discharge pipe at its lower end, and a solenoid valve 11 is installed in the middle of the discharge pipe. The input end of the solenoid valve 11 is electrically connected to the output end of the controller 13. The top chamber 3 is equipped with a feed pipe at its upper end and a sealing plate at its upper end. The sealing plate is connected to the front end of the upper surface of the top chamber 3 by bolts. The sealing plate is disassembled periodically by removing the bolts. Then, the waste residue at the arc-shaped filter plate 86 is cleaned by inserting the external material pump suction hose into the interior of the top chamber 3. After baking, the controller 13 activates the solenoid valve 11, and the solenoid valve 11 opens, allowing the high-alumina castable material for the kiln to be removed through the discharge pipe.

[0027] The working principle of the rapid baking device for high-alumina castable refractory for kilns provided by this utility model is as follows: During operation, personnel first use the support frame 1 to stably place the baking chamber 2, the top chamber 3, and other mechanisms in a horizontal working area. After stable placement, personnel use the controller 13 to activate the heater 10 to heat the air inside the baking chamber 2. Simultaneously, high-alumina castable refractory for kilns is added into the top chamber 3 through the feed pipe. After the addition is completed, personnel use the controller 13 to activate the motor 71. The output shaft of the motor 71 rotates, driving the drive shaft 72 to rotate. The rotation of drive shaft 72 drives drive pulley 75 to rotate. Drive pulley 75 drives drive pulley 77 and driven pulley 78 to rotate via a transmission belt. The rotation of drive pulley 77 drives drive shaft 76 to rotate. The rotation of drive shaft 76 drives transmission gear to rotate. The rotation of transmission gear drives driven gear 87 to rotate. The rotation of driven gear 87 drives rotating drum 81 to rotate. The rotation of rotating drum 81 drives rotating drum 82 to rotate. The rotation of rotating drum 82 drives three grinding rollers 83 to rotate around the central axis of rotating drum 81. The driven helical gears 85 are all meshed with the fixed helical gear 84. The rotating roller 83 rotates under the combined action of the rotating roller and the arc-shaped filter plate 86, thus grinding the high-alumina castable for the kiln. The ground high-alumina castable enters the baking chamber 2 through the arc-shaped filter plate 86. At the same time, the driven pulley 78 rotates, driving the rotating column 12 to rotate. The rotating column 12 rotates, driving the stirring frame to rotate, and simultaneously driving the fixed helical gear 84 to rotate. The rotation direction of the fixed helical gear 84 is opposite to the revolution direction of the driven helical gear 85. Meanwhile, the drive shaft 72 rotates, driving the drive gear 7 The rotation of the 3rd column drives the driven gear ring 74 to rotate, which in turn drives the baking chamber 2 to rotate. The baking chamber 2 drives the evenly distributed stirring rods to rotate. The rotation direction of the baking chamber 2 is opposite to that of the rotating column 12, thereby achieving coaxial and opposite rotation of the high-alumina castable for the kiln. This improves the degree of freedom of the high-alumina castable for the kiln to disperse inside the baking chamber 2, thus effectively improving the baking efficiency of the high-alumina castable for the kiln. After baking is completed, the controller 13 activates the solenoid valve 11, which opens the solenoid valve 11, allowing the high-alumina castable for the kiln to be removed through the discharge pipe.

[0028] It is worth noting that the controller 13 disclosed in the above embodiments controls the operation of the motor 71, heater 10 and solenoid valve 11 using methods commonly used in the prior art.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
