[0024] During use, the operator opens the gate 10 to add the calcined calcium oxide raw material into the interior of the furnace body 4, and then locks the gate 10 by the locking bolt 11 to ensure that the gate 10 seals the furnace body 4; after calcination, the discharge port of the furnace body 4 is rotated downward by controlling the self-locking drive motor 8, and then the locking bolt 11 is unscrewed to open the gate 10, and the retraction movement of the hydraulic telescopic rod 14 drives the end of the furnace body 4 close to the discharge port to tilt downward. At this time, the calcined calcium oxide raw material will slide out of the discharge port and fall into the collection box. The discharge method of the device is simple and easy to operate, and is convenient for operators to use.

[0025] In this embodiment, a plurality of stirring rods 13 are evenly fixedly installed on the outer surface of the rotating shaft 12, and the plurality of stirring rods 13 are arranged inside the furnace body 4.

[0026] The second gear 9 is driven to rotate by the self-locking drive motor 8, so that the second gear 9 drives the first gear 7 to rotate, and the first gear 7 drives the furnace body 4 to rotate through the fixed sleeve 5, so that the stirring rod 13 rotates relative to the furnace body 4. Through the rotation of the stirring rod 13 and the furnace body 4, the calcium oxide raw material inside the furnace body 4 is stirred, ensuring that the calcium oxide is heated evenly and improving the calcination effect.

[0027] In this embodiment, a heating plate 2 is fixedly mounted on the upper surface of the base 1 , and the heating plate 2 is disposed above the furnace body 4 .

[0028] The furnace body 4 is heated by the heating plate 2, so that the interior of the furnace body 4 generates high temperature, and the calcium oxide raw material is calcined.

[0030] It should be noted that when the utility model is in use, the operator opens the gate plate 10 to add the calcined calcium oxide raw material into the interior of the furnace body 4, and then locks the gate plate 10 by the locking bolt 11 to ensure that the gate plate 10 seals the furnace body 4; heats the furnace body 4 by the heating plate 2 to generate high temperature inside the furnace body 4 to calcine the calcium oxide raw material; drives the second gear 9 to rotate by the self-locking drive motor 8, so that the second gear 9 drives the first gear 7 to rotate, and the first gear 7 drives the furnace body 4 to rotate through the fixed sleeve 5, so that the stirring rod 13 rotates relative to the furnace body 4, and the stirring rod 13 rotates relative to the furnace body 4. The rotation of the rod 13 and the furnace body 4 stirs the calcium oxide raw material inside the furnace body 4, ensuring that the calcium oxide is heated evenly and improving the calcination effect. After the calcination is completed, the discharge port of the furnace body 4 is rotated downward by controlling the self-locking drive motor 8, and then the locking bolt 11 is unscrewed to open the gate 10. Through the retraction movement of the hydraulic telescopic rod 14, the end of the furnace body 4 close to the discharge port is driven to tilt downward. At this time, the calcined calcium oxide raw material will slide out of the discharge port and fall into the collection box. The discharge method of the device is simple and easy to operate, and is convenient for operators to use.
