[0023] For rapid separation of calcium aluminate and aluminum ash. Figure 1-Figure 5In this embodiment, a collecting chamber 3 connected to the separation screen 2 is provided inside the aluminum ash box 1.

[0025] In order to automatically discharge the aluminum ash. In this embodiment, see Figure 1-Figure 5 , an ash outlet 17 is provided on the side of the aluminum ash box 1. An ash outlet plate 18 is rotatably provided at the inner bottom end of the collecting chamber 3, and the ash outlet plate 18 is tilted along the side direction of the aluminum ash box 1.

A plurality of springs 19 are fixedly provided between the bottom of the highest end of the ash outlet plate 18 and the aluminum ash box 1, and at least one vibrator 20 is fixedly provided at the bottom of the highest end of the ash outlet plate 18. The vibrator 20 is centrally controlled by a control module. The ash outlet plate 18 is swung up and down around the rotation point between the ash outlet plate 18 and the aluminum ash box 1 by the vibrator 20 and the spring 19, so that the aluminum ash falling on the ash outlet plate 18 is moved to the ash outlet 17, so as to facilitate its subsequent collection. The side of the aluminum ash box 1 is also hingedly provided with a shielding plate 21 that can block the ash outlet 17. At the same time, its own mass and gravity seal the aluminum ash box 1. When there is a lot of aluminum ash, it is pushed open to discharge the aluminum ash, which is convenient for stacking the aluminum ash in the collection chamber 3.

[0026] In order to collect dust. Figure 1-Figure 4, a collecting barrel 4 is fixedly provided on the side of the aluminum ash box 1, and a collecting port 5 of the collecting barrel 4 is located directly above the separation screen 2 and the outlet end of the collecting barrel 4 is communicated with the collecting chamber 3. The collecting barrel 4 is located on the opposite side of the ash outlet 17 and the collecting barrel 4 is communicated with the collecting chamber 3, and a supporting frame 22 for supporting the collecting barrel 4 is fixedly provided on the side of the aluminum ash box 1. An expansion port 23 with a small upper and large lower structure is fixedly provided at the collecting port 5 of the collecting barrel 4. An exhaust fan 24 is fixedly provided at the collecting port 5 of the collecting barrel 4, and a second motor 25 for controlling the operation of the exhaust fan 24 is fixedly provided at the top of the collecting barrel 4. The second motor 25 is centrally controlled by the control module. The dust is collected by the exhaust fan 24 and the expansion port 23, and the dust is discharged into the collecting chamber 3 to avoid the aluminum ash from scattering, causing unnecessary economic losses and avoiding harm to the human body.

[0027] The method of using the automatic aluminum ash collection device during the calcination of calcium aluminate of the utility model is as follows: First, the first motor 15, the second motor 25 and the exciter 20 are controlled by the control module. When the calcium aluminate and aluminum ash calcined in the rotary furnace fall from the outlet, they are caught by the high end of the separation screen 2 and moved to the bottom end on the separation screen 2. At this time, the power output by the first motor 15 is decelerated and torque-increased by the reducer to control the rotation of the second gear 16, thereby rotating the first gear 14 meshing with it, and rotating the roller 10. At this time, the C-shaped frame 12 is driven by the eccentric column 11 and the connecting frame 13 to drive the separation screen 2 to swing up and down around the rotation point between it and the aluminum ash box 1, so that the calcium aluminate and aluminum ash of different particle sizes jump up and down, and quickly distinguish between the upper and lower layers. At this time, the aluminum ash is located in the lower layer. During this process, the open end of the C-shaped frame 12 moves in the slide 8. Calcium aluminate and aluminum ash move along the separation screen 2. During this process, the aluminum ash is blocked by the blocking plate 7, and the movement of the aluminum ash is blocked, and the aluminum ash is made to fall into the ash discharge plate 18 inside the collection chamber 3 through the separation groove 6. Calcium aluminate and aluminum ash are prevented from being mixed together, which is inconvenient to separate and affects the quality of the subsequent calcium aluminate after crushing. During this process, the exhaust fan 24 is controlled by the second motor 25 to draw the dust into the collection tube 4 through the expansion port 23, and the dust is discharged into the collection chamber 3 through the connection between the collection tube 4 and the collection chamber 3. The dust at the outlet of the rotary furnace is collected to prevent the aluminum ash from scattering, causing unnecessary economic losses and avoiding harm to the human body.

[0028] The vibrator 20 works, and the spring 19 causes the ash discharging plate 18 to swing up and down around the rotation point between the ash discharging plate 18 and the aluminum ash box 1, so that the aluminum ash entering the collecting chamber 3 is accumulated and moves to the lower end of the ash discharging plate 18. In this process, the aluminum ash box 1 is sealed by the shielding plate 21, which facilitates the accumulation of the aluminum ash in the collecting chamber 3. When there is a lot of aluminum ash, the shielding plate 21 is pushed open to discharge the aluminum ash from the ash discharging port 17, which is convenient for its collection.
