[0012] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, in the initial state, the two docking plates are in a state of docking with each other to ensure the sealing of the interior of the roasting furnace. When it is necessary to feed alumina, the output end of the first electric push rod is first controlled to contract to drive the uniform dispersing device to descend. When it descends to a certain height, the trigger blocks on both sides of the sealed fireproof box descend to the inside of the openings on both sides of the top of the docking box and contact the side ends of the two docking plates respectively. The arc surface at the bottom of the trigger block forms an extrusion on the oblique edge of the top of the docking plate to drive the two docking plates to slide synchronously away from the opposite side. The first spring contracts to expose the bottom of the docking groove and the feed port of the roasting furnace. At this time, the sealed fireproof box continues to descend to drive the uniform dispersing device to enter the interior of the roasting furnace for feeding. At this time, the sealed fireproof box is completely in the docking groove and the two fit each other, and then the feed port of the roasting furnace is sealed again, thereby achieving the effect of ensuring the sealing of the feed when transporting alumina to the interior of the roasting furnace and preventing external air and impurities from entering the furnace.

[0013] In the present invention, after the uniform dispersing device moves to the inside of the roasting furnace, the height of the eight material boxes can be adjusted by controlling the operation of the second electric push rod, thereby controlling the distribution range of the alumina. After adjusting the height of the material boxes, in the initial state, the eight material boxes are in a retracted state and are located in a smaller area in the middle of the roasting furnace. First, the driving motor is controlled to drive the driving rod connected thereto to deflect clockwise, and then, with the cooperation of the eight linkage rods, the remaining three driving rods are driven to deflect synchronously clockwise, thereby driving the eight material boxes to deflect and move synchronously toward the direction close to the inner wall of the roasting furnace. As the material boxes move, the material door at the bottom of the material boxes detaches from the baffle plate, allowing the material door to move downward. The spring extends, and as the box moves, the alumina in the box falls out, falls on the top of the door, and slides down through the inclined surface at the top of the door into the roasting furnace, and is evenly distributed in a circular shape inside the roasting furnace. After the delivery of alumina is completed, the conveying end of the drive motor is controlled to reverse, and the eight boxes are reset. During the resetting process, the door is squeezed by the inclined surface at the top of the baffle plate and resets to close the bottom of the box again. Through the above operation, when the alumina is transported to the roasting furnace through the feeding equipment, the alumina entering the furnace is evenly dispersed to improve the quality of the alumina.

[0014] In the present invention, before conveying alumina into the roasting furnace, it is necessary to first put the alumina to be fed into eight feed boxes in turn, pull the sealing door on the top of each pouring port in turn to expose the pouring port, and then pour the alumina to be fed into the corresponding position of the feed box evenly and dispersedly through the pouring port. After pouring, release the sealing door, and under the action of the second spring, the sealing door automatically resets to seal the pouring port, thereby ensuring the sealing performance of the roasting furnace during the feeding operation.

[0015] In the present invention, as the discharge box is deflected toward the inner wall of the roasting furnace to discharge alumina, as the linkage rod rotates on the connecting piece, the first gear is driven to rotate a certain angle, and then the second gear is driven to rotate. Since the diameter of the first gear is larger than the diameter of the second gear, the vibration cam connected to the second gear is driven to rotate several circles, so that the vibration cam hits the inner wall of the discharge box during the rotation process, thereby driving the discharge box to vibrate to a certain amplitude, thereby more thoroughly discharges the alumina inside the discharge box into the roasting furnace, thereby avoiding residual alumina inside the discharge box after the discharge is completed.

A placement slot is provided in the middle of the bottom of the sealed fireproof box 4.

There are four driving rods 614, and the four driving rods 614 are evenly distributed at a certain angle below the driving plate 612. One end of one of the driving rods 614 is connected to the output end of the driving motor 613, and one end of the other three driving rods 614 is respectively rotatably connected to the other three corners of the bottom of the driving plate 612, and the four driving rods 614 are at the same horizontal height. The dispersing assembly 62 includes a linkage rod 621 and a connecting piece 622. Each material box 63 is provided with a material discharge cavity which is arranged through from top to bottom. There are eight connecting pieces 622. A connecting piece 622 is arranged in the middle of the top of each material discharge cavity. One end of each of the four material discharge boxes 63 is rotatably connected to the end of the adjacent driving rod 614 respectively. There are eight linkage rods 621. The linkage rods 621 are arranged in a V shape. The middle part of each linkage rod 621 is rotatably connected to the middle part of a connecting piece 622 respectively.

After adjusting the height of the material boxes 63, in the initial state, the eight material boxes 63 are in a retracted state and are located in a smaller area in the middle of the roasting furnace 2. First, the driving motor 613 is controlled to work to drive the driving rod 614 connected thereto to deflect clockwise, and then, with the cooperation of the eight linkage rods 621, the remaining three driving rods 614 are driven to deflect clockwise synchronously, thereby driving the eight material boxes 63 to deflect and move synchronously toward the inner wall of the roasting furnace 2. As the material boxes 63 move, the material discharge door 64 at the bottom of the material boxes 63 separates from the shielding plate 65, allowing the material to be discharged. The door 64 descends to expose the bottom of the discharge box 63, and the spring stretches. As the discharge box 63 moves, the alumina in the discharge box 63 is scattered, and falls on the top of the discharge door 64 and slides into the roasting furnace 2 through the inclined surface at the top of the discharge door 64, and is relatively evenly distributed in a circular shape inside the roasting furnace 2. After the alumina is delivered, the conveying end of the drive motor 613 is controlled to reverse, and the eight discharge boxes 63 are driven to reset. During the resetting process, the discharge door 64 is squeezed by the inclined surface of the top of the baffle plate 65 and resets to close the bottom of the discharge box 63 again. Through the above operation, when the alumina is transported to the roasting furnace 2 through the feeding equipment, the alumina entering the furnace is ensured to be dispersed more evenly to improve the quality of the alumina.

After pouring, release the sealing door 661, and under the action of the second spring 662, the sealing door 661 automatically resets to seal the pouring port, thereby ensuring the sealing performance of the roasting furnace 2 during the feeding operation.
