[0002] High-purity alumina is a raw material for artificial gemstones. When in use, it needs to be heated and melted by a roasting furnace. In order to ensure safety and heat preservation effects, the existing roasting furnace has a small furnace opening. When in use, high-purity alumina is added into the furnace opening manually or by a manipulator. However, due to the high temperature inside the furnace, it is inconvenient for both manual labor and the manipulator to be used inside the furnace, and a special feeding device is required to put alumina into the roasting furnace. However, the traditional feeding device has the following problems: First, the uniformity of feeding is very important. If the feeding is uneven, it may lead to uneven temperature distribution inside the furnace, affecting the product quality. The traditional feeding device cannot guarantee the uniformity of alumina feeding and is prone to accumulation. Second, the sealing performance is not good enough when transporting alumina into the roasting furnace through the feeding device, and external air and impurities are likely to enter the furnace, affecting the quality of high-purity alumina. There is a lack of a device that can ensure the sealing performance during feeding, prevent external air and impurities from entering the furnace, and at the same time ensure that the alumina entering the furnace is dispersed relatively evenly to improve the quality of alumina.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] In the present invention, in the initial state, the two docking plates are in a mutually docked state to ensure the sealing performance inside the roasting furnace. When alumina feeding work needs to be carried out, first, control the output end of the first electric push rod to contract, driving the uniform material scattering device to descend. When it descends to a certain height, the trigger blocks on both sides of the sealed fireproof box descend to penetrate into the openings on both sides of the top of the docking box and respectively contact the side ends of the two docking plates. The arc surface at the bottom of the trigger block forms extrusion on the hypotenuse at the top of the docking plate, driving the two docking plates to slide synchronously in the direction away from the opposite side. The first spring contracts, thereby exposing the bottom of the docking groove and the feed port of the roasting furnace. At this time, the sealed fireproof box continues to descend, driving the uniform material scattering device into the roasting furnace to facilitate the feeding work. And at this time, the sealed fireproof box is completely inside the docking groove and they fit with each other, thereby sealing the feed port of the roasting furnace again, thus achieving the effect of ensuring the sealing performance during feeding and preventing external air and impurities from entering the furnace when transporting alumina into the roasting furnace.

[0014] In the present invention, after the uniform material scattering device moves into the roasting furnace, by controlling the second electric push rod to work, the height of the eight feeding boxes can be adjusted, thereby controlling the distribution range of alumina. After adjusting the height of the feeding boxes, in the initial state, the eight feeding boxes are in a contracted state and are located in a relatively small area in the middle of the roasting furnace. First, control the driving motor to work, driving the driving rod connected to it to deflect clockwise. Then, with the cooperation of the eight linkage rods, drive the other three driving rods to deflect clockwise synchronously, thereby driving the eight feeding boxes to deflect and move synchronously in the direction close to the inner side wall of the roasting furnace. As the feeding boxes move, the feeding doors at the bottom of the feeding boxes disengage from the baffle plates, causing the feeding doors to descend, thereby exposing the bottoms of the feeding boxes. The springs elongate. As the feeding boxes move, the alumina inside the feeding boxes scatters accordingly, and falls on the top of the feeding doors and slides into the roasting furnace through the inclined surfaces at the top of the feeding doors, and is distributed in a relatively uniform circular shape inside the roasting furnace. After the alumina is put in, control the reverse rotation of the output end of the driving motor, and drive the eight feeding boxes to reset accordingly. During the reset process, the feeding doors are squeezed by the inclined surfaces at the top of the baffle plates and reset to close the bottoms of the feeding boxes again. Through the above operations, when transporting alumina into the roasting furnace through the feeding equipment, the effect of ensuring that the alumina entering the furnace is dispersed relatively evenly to improve the quality of alumina is achieved.

[0015] In the present invention, before transporting alumina into the roasting furnace, it is necessary to sequentially put the alumina to be fed into the eight feeding boxes. Pull the sealing doors at the tops of each pouring port in turn to expose the pouring ports, and then pour the alumina to be fed evenly and dispersedly into the corresponding feeding boxes through the pouring ports. After pouring, release the sealing doors, and the sealing doors automatically reset under the action of the second springs to seal the pouring ports, thereby ensuring the sealing performance of the roasting furnace during the feeding operation.

[0016] In the present invention, when alumina is fed while the feeding box deflects towards the inner wall of the roasting furnace, as the linkage rod rotates on the connecting piece, the first gear is driven to rotate by a certain angle, and then the second gear is driven to rotate. Since the diameter of the first gear is larger than that of the second gear, the vibration cam connected to the second gear is driven to rotate several circles, so that the vibration cam knocks on the inner side wall of the feeding box during rotation, thereby driving the feeding box to vibrate with a certain amplitude, and further feeding the alumina inside the feeding box more thoroughly into the roasting furnace, thus avoiding the residue of alumina inside the feeding box after feeding is completed.

[0032] In this embodiment, as Figure 2 and Figure 10As shown in the figure, the driving furnace feeding assembly 3 includes a first electric push rod 31 and a connecting plate 32. The first electric push rod 31 is vertically arranged at the top of the base plate 1 with its output end facing upward. The connecting plate 32 is horizontally arranged above the first electric push rod 31. One end of the connecting plate 32 is connected to the output end of the first electric push rod 31, and the other end of the connecting plate 32 is connected to the side end of the sealed fireproof box 4;

[0033] The docking and sealing device 5 includes a docking box 51, a docking groove 52, an installation cavity 53, a docking plate 54, a trigger block 55 and a first spring 56. The docking box 51 is arranged at the top of the roasting furnace 2. A vertically penetrating docking groove 52 is provided in the middle of the docking box 51. The bottom of the docking groove 52 is communicated with the feeding port at the top of the roasting furnace 2 and has the same size, and the size of the docking groove 52 fits the size of the sealed fireproof box 4. Installation cavities 53 are provided on both sides inside the docking box 51, and the installation cavities 53 are located on both sides of the docking groove 52. There are two docking plates 54, and the two docking plates 54 are symmetrically arranged inside the two installation cavities 53. The adjacent ends of the two docking plates 54 respectively pass through both sides of the docking groove 52 and are slidably connected thereto, and the adjacent ends of the two docking plates 54 are docked with each other to close the bottom of the docking groove 52. The tops of the mutually remote ends of the two docking plates 54 are provided with bevels, and openings are provided in the corresponding areas at the top of the docking box 51 and the ends of the two docking plates 54 with bevels.

[0034] Magnetic sealing gaskets are provided at the mutually docking ends of the two docking plates 54, and the docking plates 54 are made of refractory materials;

[0035] When the device is in use, in the initial state, the two docking plates 54 are in a state of mutual docking to ensure the sealing performance inside the roasting furnace 2. When the alumina feeding work needs to be carried out, first control the output end of the first electric push rod 31 to contract, driving the uniform material scattering device 6 to descend. When it descends to a certain height, the trigger blocks 55 on both sides of the sealing fireproof box 4 descend to penetrate into the openings on both sides of the top of the docking box 51 and respectively contact the side ends of the two docking plates 54. The arc surface at the bottom of the trigger block 55 forms a squeeze on the hypotenuse at the top of the docking plate 54, driving the two docking plates 54 to slide synchronously in the direction away from the opposite side, and the first spring 56 contracts. As a result, the bottom of the docking groove 52 and the feeding port of the roasting furnace 2 are exposed. At this time, the sealing fireproof box 4 continues to descend, driving the uniform material scattering device 6 into the roasting furnace 2 to facilitate the feeding work. And at this time, the sealing fireproof box 4 is completely inside the docking groove 52 and they fit each other, thereby sealing the feeding port of the roasting furnace 2 again. Thus, when transporting alumina into the roasting furnace 2, the sealing performance during feeding is ensured, and the effect of preventing external air and impurities from entering the furnace is achieved.

[0036] In this embodiment, as Figures 3 to 8 shown, the driving assembly 61 includes a second electric push rod 611, a driving plate 612, a driving motor 613 and a driving rod 614. A placement groove is provided in the middle of the bottom of the sealing fireproof box 4. The second electric push rod 611 is vertically arranged inside the placement groove and the output end of the second electric push rod 611 is arranged downward. The driving plate 612 is horizontally arranged in the placement groove and the top of the driving plate 612 is connected to the output end of the second electric push rod 611. The driving plate 612 is square-shaped. The driving motor 613 is vertically arranged at a corner at the bottom of the driving plate 612, and the output end of the driving motor 613 is arranged downward. 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 driving rod 614 is connected to the output end of the driving motor 613, and the other ends of the other three driving rods 614 are respectively rotatably connected to the other three corners at the bottom of the driving plate 612, and the four driving rods 614 are at the same horizontal height;

[0037] The spreading assembly 62 includes a linkage rod 621 and a connecting piece 622. Each blanking box 63 is provided with a vertically penetrating blanking cavity. There are eight connecting pieces 622, and one connecting piece 622 is provided in the middle of the top of each blanking cavity. One end of four blanking boxes 63 is respectively rotatably connected to the end of the adjacent driving rod 614. There are eight linkage rods 621, and the linkage rods 621 are V-shaped. The middle part of each linkage rod 621 is respectively rotatably connected to the middle part of a connecting piece 622, and the two ends of each linkage rod 621 are respectively rotatably connected to the ends of the adjacent blanking boxes 63;

[0038] A blanking door 64 is slidably connected up and down to the bottom of each blanking box 63. A spring is provided at the sliding connection between the blanking door 64 and the blanking box 63. When the spring is in a contracted state, the blanking door 64 closes the bottom of the blanking cavity. An inclined surface is provided on one side of the blanking door 64 and the inner part of the blanking cavity close to the blanking door 64. A baffle 65 is horizontally arranged at the bottoms of the eight blanking boxes 63. The top of the baffle 65 is connected to the bottom of the driving plate 612. The outer end of the baffle 65 abuts against one end of the eight blanking doors 64. An inclined surface is provided on the outer side of the top of the baffle 65. The driving assembly 61, the spreading assembly 62, the blanking door 64 and the baffle 65 are all made of fire-resistant materials;

[0039] After the uniform material spreading device 6 moves into the roasting furnace 2, by controlling the operation of the second electric push rod 611, the heights of the eight blanking boxes 63 can be adjusted, thereby controlling the distribution range of alumina. After adjusting the heights of the blanking boxes 63, in the initial state, the eight blanking boxes 63 are in a contracted state and located in a smaller area in the middle of the roasting furnace 2. First, control the driving motor 613 to work and drive the driving rod 614 connected thereto to deflect clockwise. Then, with the cooperation of the eight linkage rods 621, drive the other three driving rods 614 to deflect clockwise synchronously, thereby driving the eight blanking boxes 63 to deflect and move synchronously towards the direction close to the inner side wall of the roasting furnace 2. As the blanking box 63 moves, the blanking door 64 at the bottom of the blanking box 63 disengages from the baffle 65, causing the blanking door 64 to descend, thereby exposing the bottom of the blanking box 63. The spring elongates. As the blanking box 63 moves, the alumina inside the blanking box 63 scatters accordingly, and falls on the top of the blanking door 64 and slides towards the inside of the roasting furnace 2 through the inclined surface on the top of the blanking door 64, and is distributed in a relatively uniform circular shape inside the roasting furnace 2. After the alumina is put in place, control the conveying end of the driving motor 613 to reverse, and drive the eight blanking boxes 63 to reset accordingly. During the reset process, the blanking door 64 is squeezed by the inclined surface at the top of the baffle 65 and resets to seal the bottom of the blanking box 63 again. Through the above operations, when the alumina is conveyed into the roasting furnace 2 through the feeding device, the effect of ensuring that the alumina entering the furnace is dispersed relatively uniformly to improve the quality of alumina is achieved.

[0040] In this embodiment, as Figure 9 shown, eight up-and-down through blanking ports are provided at the top of the sealed fireproof box 4, and each blanking port corresponds to and has the same shape as a blanking box 63. A feeding assembly 66 is provided at each blanking port. Each feeding assembly 66 includes a sealing door 661 and a second spring 662. The sealing door 661 is arranged at the blanking port to seal the blanking port. The sealing door 661 is slidably connected to the top of the sealed fireproof box 4, and a second spring 662 is provided at the sliding connection;

[0041] Before delivering alumina into the interior of the roasting furnace 2, it is necessary to sequentially feed the alumina to be fed into the eight feeding boxes 63. Pull the sealing doors 661 at the top of each discharging port in sequence to expose the discharging ports, and then evenly and dispersedly pour the alumina to be fed into the corresponding feeding boxes 63 through the discharging ports. After pouring, release the sealing doors 661. Under the action of the second spring 662, the sealing doors 661 automatically reset to seal the discharging ports, thereby ensuring the sealing performance of the roasting furnace 2 during the feeding operation.

[0042] In this embodiment, as Figure 11 and Figure 12 shown, it further includes a vibration assembly 7. A vibration assembly 7 is provided inside each feeding box 63. The vibration assembly 7 includes a first gear 71, a second gear 72, and a vibration cam 73. The first gear 71 is arranged inside the feeding box 63 and at the rotational connection of the linkage rod 621 and the connecting member 622. The second gear 72 is rotatably arranged at the bottom of the connecting member 622. The diameter of the first gear 71 is larger than that of the second gear 72, and the first gear 71 meshes with the second gear 72. The vibration cam 73 is arranged inside the feeding box 63 and is coaxially connected to the second gear 72, and one side of the vibration cam 73 contacts the inner side of the feeding box 63;

[0043] When the feeding box 63 deflects towards the inner wall of the roasting furnace 2 to discharge alumina, as the linkage rod 621 rotates on the connecting member 622, it drives the first gear 71 to rotate a certain angle, and then drives the second gear 72 to rotate. Since the diameter of the first gear 71 is larger than that of the second gear 72, it drives the vibration cam 73 connected to the second gear 72 to rotate several circles, so that the vibration cam 73 knocks on the inner side wall of the feeding box 63 during rotation, thereby driving the feeding box 63 to vibrate with a certain amplitude, and further discharging the alumina inside the feeding box 63 more thoroughly into the interior of the roasting furnace 2, thus avoiding the residue of alumina inside the feeding box 63 after the discharging is completed.
