[0002] Pre-desiliconization of alumina slurry refers to a process step in the alumina production process. Its purpose is to remove silicon impurities as much as possible in the alumina production process to improve the purity and quality of the alumina product. Silicon is one of the main impurities in alumina slurry, and its presence will reduce the quality of the alumina product. By removing silicon in advance, the impurity content in the product can be reduced, thereby improving the purity and quality of the alumina product.

[0033] Working principle: When the device is needed, pour the prepared liquid into the storage tank 6, and pour it into the feeding tube 8 through the discharge pipe 7, start the hydraulic press 12, and when the hydraulic press 12 is working, it can push the fixed column 10 to slide, and when the fixed column 10 slides, it can drive the slide plate 5 to slide on the inner wall of the concave plate 4, and when the slide plate 5 slides, it can drive the feeding tube 8 to slide.

When the feeding tube 8 moves forward, it will cause the rotating column 11 inside the fixed column 10 to rotate, so that the cover plate 9 is turned over. Because the capacity of the feeding tube 8 is fixed, each time the material is discharged, it will be put in. The quantitative preparation liquid can achieve the effect of quantitatively adding the preparation liquid to improve the pre-desiliconization efficiency. The preparation liquid is put into the lower hopper 16 and transported to the heating tank 18 through the delivery pipe 17. When heated, the water vapor moves upward.

Then, it is transported into the annular water pipe 20 through the second water pump 40 for recycling, thereby achieving the effect of improving the utilization rate of the heat energy of the exhaust steam and condensed water. When the cold water enters the annular water pipe 20 through the second water pump 40 When the pipe 20 is connected, the outer wall of the second water pump 40 is provided with a flow control device. The rotating knob 31 drives the threaded rod 30 to rotate inside the fixed rod 29 and prompts the rotating block 32 to drive the sliding bar 33 to move. While the rotating block 32 rotates on the outer wall of the sliding bar 33, it drives the sliding bar 33 to slide on the upper surface of the base 28, thereby causing the fixed frame 34 to rotate on the inner wall of the base 28. At this time, the base 28 drives the second fixed shaft 37 to move, and the movement of the second fixed shaft 37 drives the sliding frame 38 to move. However, since the sliding bar 36 slides on the inner wall of the sliding frame 38, and the first fixed shaft 35 is fixed on the upper surface of the base 28 and rotates to connect to the The inside of the slide bar 36 makes the slide bar 36 slide on the inner wall of the slide frame 38, thereby driving the rotating plate 39 to move. The degree of rotation of the knob 31 can control the degree of closing of the rotating plate 39, thereby controlling the size of the water flow delivered by the second water pump 40 to the annular water pipe 20, thereby achieving the effect of adjusting the water flow size, and then reasonably distributing the heat of the exhaust steam and condensed water. The device can not only achieve the effect of quantitatively adding the formulation liquid to improve the pre-desiliconization efficiency, but also achieve the effect of improving the utilization rate of the thermal energy of the exhaust steam and condensed water, and can also achieve the effect of adjusting the water flow size, and then reasonably distributing the heat of the exhaust steam and condensed water.
