[0019] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0020] like Figure 1-Figure 4 A calcined alumina drying device shown in the figure includes a drying box 1, and a lifting mechanism is arranged inside the drying box 1. The lifting mechanism includes a stepper motor 3 fixedly installed on one side of the top of the drying box 1, and a threaded rod 4 is fixedly connected to the output end of the stepper motor 3, and the threaded rod 4 is connected to the transport block 5 through a thread, and a placement groove 6 is arranged inside the transport block 5. Small motors 7 are fixedly installed at the bottom ends of both sides of the transport block 5, and a rotating wheel 8 is fixedly connected to the output end of the small motor 7. The stepper motor 3 in the lifting mechanism can transport the drying plate 14 to between every two pairs of placement plates 9, and then the rotating wheel 8 is driven by the small motor 7 to rotate, and the drying plate 14 is moved to the placement plate 9 to complete the loading of the drying plate 14. The drying plate 14 can be placed on the placement plate 9 of any height by the lifting mechanism, which ensures the alumina drying efficiency while saving manpower.
[0021] A plate withdrawing mechanism is provided inside the drying box 1, and the plate withdrawing mechanism includes a placing plate 9 fixedly connected to the inner wall of the drying box 1, a plate withdrawing groove 10 is provided on one side of the placing plate 9, a rotating block 11 is rotatably connected to the inner wall of the drying box 1, a paddle plate 12 is provided on one side of the rotating block 11, and a limiting column 13 is fixedly connected to the inner wall of the drying box 1. The paddle plate 12 can be driven to rotate by the rotating block 11 in the plate withdrawing mechanism, and the rotating block 11 is driven by the motor inside the drying box 1, so as to push the drying plate 14 in the placing plate 9 into the placing groove 6, and then the drying plate 14 can be taken out by using the lifting mechanism, thereby completing the unloading of the drying plate 14.
[0022] A sealed door 2 is rotatably connected to one side of the drying box 1. A heat dissipation mechanism 17 is installed inside the drying box 1. The heat dissipation mechanism 17 can ventilate the interior of the drying box 1 and maintain the temperature inside the box to prevent the aluminum oxide from deforming due to excessive temperature and causing uneven baking. A drying mechanism 18 is installed on the inner wall of the drying box 1. The drying mechanism 18 can bake the aluminum oxide in the drying plate 14 to dry the aluminum oxide.
[0023] The placement plates 9 form a pair of two, and each pair of placement plates 9 is internally slidably connected with a drying plate 14 . Every two pairs of placement plates 9 fix the drying plates 14 . The drying plates 14 are used to store the alumina that needs to be dried, and the placement plates 9 are used to fix the drying plates 14 .
[0024] Blocks 15 are fixedly connected to both sides of the drying plate 14, and a leakage hole 16 is provided at the bottom end of the drying plate 14. The drying plate 14 is arranged inside the two pairs of placement plates 9 through the block 15. Since the dried alumina does not absorb moisture, the leakage hole 16 is required to discharge the moisture discharged during the drying process of the alumina to prevent the moisture from accumulating in the alumina and affecting the efficiency of the alumina drying.
[0025] A limiting rod is provided inside one side of the drying box body 1, and the threaded rod 4 corresponds to the limiting rod. The other end of the transport block 5 is slidably connected to the surface of the limiting rod. The rotating wheel 8 is provided inside the placement groove 6. The rotating wheel 8 can rotate to transport the drying plate 14 to between the placement plates 9, and cooperate with the lifting mechanism to complete the loading of the drying plate 14. The stepping motor 3 is controlled by a computer to generate electric pulses, thereby controlling the movement of the stepping motor 3.
[0026] A plate withdrawal groove 10 is provided inside each placement plate 9. A pair of placement plates 9 are provided with two rotating blocks 11 and four limiting columns 13. Two dial plates 12 are respectively arranged between the two limiting columns 13. The limiting columns 13 can limit the dial plates 12 to prevent the dial plates 12 from rotating to the outside of the placement plates 9. The drying plates 14 cannot be blocked, causing the drying plates 14 to collide with the drying box body 1, thereby reducing the service life of the device.
[0027] Working principle: First, spread the aluminum oxide to be dried on the inside of the drying plate 14, then insert the drying plate 14 into the placement slot 6, then the stepper motor 3 will drive the threaded rod 4 to rotate, so that the transport block 5 is lifted, and the stepper motor 3 is controlled by a computer to control the height of the transport block 5, and accurately lift the transport block 5 to between each pair of placement plates 9. When the placement slot 6 is located between the two placement plates 9, the small motor 7 will drive the rotating wheel 8 to rotate, and the drying plate 14 will be transported to the placement plate 9, and then the dial plate 12 will limit the drying plate 14, so that the drying plate 14 is fixed. The drying plate 14 can be placed in the drying box 1 by reciprocating in this way, and the alumina can be dried. When the alumina in the drying plate 14 is completely dry, the motor will drive the rotating block 11 to rotate, and at the same time, the dial plate 12 will push the drying plate 14, and push the drying plate 14 back into the placement slot 6. Then the small motor 7 will rotate in the opposite direction, and the drying plate 14 can be taken out under the action of the rotating wheel 8, thereby taking out the dried alumina. During the whole process, the drying plate 14 can be placed on the placement plate 9 at any height, which not only ensures the drying efficiency of the alumina, but also facilitates manual work.
