Description

Technical Field

[0001] The invention relates to the technical field of alumina separation and filtration, in particular to a dehydration and filtration device for high-purity alumina production. Background Art

[0002] Suction filtration, also known as reduced pressure filtration and vacuum filtration, has a dual meaning. In physical terms, suction filtration refers to the use of a vacuum pump to reduce the pressure in the suction filtration bottle to achieve the purpose of solid-liquid separation. It increases the pressure on both sides of the filter medium, speeds up the filtration rate, shortens the filtration time, and can separate the precipitate from the mother liquor as much as possible. The resulting solid precipitate is also easy to dry.

[0003] In the production of high-purity alumina, impurities in the alumina need to be cleaned, and after cleaning, the alumina and water need to be separated. A dehydration and filtration device is needed for separation. During use, the existing dehydration and filtration device uses the negative pressure of a vacuum pump to make water pass through the filter cloth to achieve solid-liquid separation. During the long separation, more and more alumina will accumulate on the filter cloth, resulting in some water being mixed in the accumulated alumina and unable to pass through the filter cloth. After the filtration is completed, the separation effect of alumina and water is not good, which requires the operator to perform multiple separations, reducing the effect after separation.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing dehydration and filtration devices on the market, and even if the above problems can be solved, they still need to be coordinated with external tools, thus failing to achieve the desired effect.

During the vibration of the centrifugal filter box 2201, the alumina can be vibrated inside the centrifugal filter box 2201, so that the accumulated alumina can be moved, and then the water inside the accumulated alumina can be completely separated from the alumina, so that the purpose of vibrating the alumina inside the centrifugal filter box 2201 is achieved, so that the alumina can be prevented from being accumulated on the filter cloth due to long-term and large-scale solid-liquid separation of alumina, and the alumina can be moved inside the centrifugal filter box 2201, so that the water and alumina can reach the best separation state during separation, thereby increasing the separation effect;

At the same time, the support plate 2114 can also be reset by the reaction force of the spring 2113, so that the support plate 2114 can be coordinated with the rotating plate 2105 to achieve the purpose of vibrating the support plate 2114, thereby causing the centrifugal filter box 2201 to vibrate.

[0038] A support rod 2106 is fixedly installed on one side of the rotating plate 2105, and a first bearing 2107 is fixedly installed on the surface of the support rod 2106. One side of the outer ring of the first bearing 2107 is fixedly installed on the inner wall of the outer shell 11, and the second transmission wheel 2104, the rotating plate 2105 and the support rod 2106 are concentrically arranged. Through the coordinated use of the first bearing 2107 and the support rod 2106, the second transmission wheel 2104 and the rotating plate 2105 can rotate with the first bearing 2107 and the support rod 2106 as the center when rotating, so that the second transmission wheel 2104 and the rotating plate 2105 will not be deflected during the rotation process, thereby increasing stability.

[0039] The specific implementation method of this embodiment is as follows: when filtering alumina, the operator connects the connecting pipe 15 to the external vacuum pump. At this time, the operator starts the vacuum pump to form a negative pressure inside the housing 11, and draws the material into the housing 11 through the feed pipe, so that the material enters the interior of the centrifugal filter box 2201. At this time, the operator uses the external control switch and power supply to start the motor 2101. The start of the motor 2101 drives the first transmission wheel 2102 to rotate. The rotation of the first transmission wheel 2102 is driven by the belt 21 03 drives the second transmission wheel 2104 to rotate, the rotation of the second transmission wheel 2104 drives the rotating plate 2105 to rotate, the rotating plate 2105 drives the support rod 2106 to rotate through the first bearing 2107, the rotation of the rotating plate 2105 drives the pulley 2108 to rotate, so that the pulley 2108 rotates with the second transmission wheel 2104 as the center, so that the pulley 2108 cooperates with the arc groove 2115 to drive the support plate 2114 to move up and down, and the movement of the support plate 2114 drives the sliding sleeve 2112 on the sliding rod 2 The surface of the rotating plate 2105 squeezes the spring 2113. When the pulley 2108 is separated from the inner cavity of the arc groove 2115, the reaction force of the spring 2113 resets the support plate 2114. The continuous rotation of the rotating plate 2105 can drive the support plate 2114 to move up and down. The up and down movement of the support plate 2114 drives the centrifugal filter box 2201 to move up and down, so that the centrifugal filter box 2201 can vibrate. During the vibration of the centrifugal filter box 2201, the aluminum oxide can vibrate in the centrifugal filter box 2201, so that the accumulated The alumina is moved so that the water inside the accumulated alumina can be completely separated from the alumina, thereby achieving the purpose of vibrating the alumina in the centrifugal filter box 2201, so that the alumina will not be accumulated on the filter cloth due to the long-term solid-liquid separation of a large amount of alumina, avoiding the phenomenon that a large amount of alumina is accumulated on the filter cloth and causing the separation effect to deteriorate, and the alumina can be moved inside the centrifugal filter box 2201, thereby ensuring that the water and alumina can reach the best separation state during separation, thereby increasing the separation effect.

By using the fixing rods 39 and the bidirectional conical roller 310 in coordination, the two filter barrels 33 can be rotated at the same time, and water can also pass through the bidirectional conical roller 310 and enter the interior of the filter barrel 33 for secondary filtration, thereby ensuring the effect of solid-liquid separation.

[0047] A filter cloth 311 is slidably mounted on the inner wall of the outer shell 11, a handle 313 is fixedly mounted on one side of the filter cloth 311, a baffle 312 is fixedly mounted on the inner wall of the outer shell 11, the filter cloth 311 is in contact with the top of the baffle 312, and through the coordinated use of the filter cloth 311, the baffle 312 and the handle 313, a small amount of water that has not entered the filter barrel 33 can be filtered, further ensuring the effect of secondary filtration, and the operator can also disassemble the filter cloth 311 through the handle 313 to remove the aluminum oxide on the filter cloth 311.

[0048] The specific implementation of this embodiment is as follows: after the centrifugal filter box 2201 completes the filtration, the filtered water enters the interior of the funnel 31, so that the water is concentrated in the interior of the fixed tube 32. During the rotation of the first transmission wheel 2102, the fixed shaft 38 is driven to rotate, and the rotation of the fixed shaft 38 drives the small gear 37 to rotate. The rotation of the small gear 37 drives the large gear 34 to rotate slowly. The rotation of the large gear 34 drives the positioning rod 35 to rotate through the second bearing 36. The rotation of the large gear 34 simultaneously drives one of the filter barrels 33 to rotate, and the rotation of one of the filter barrels 33 drives one of the fixed rods 39 to rotate, and the rotation of one of the fixed rods 39 drives the bidirectional conical roller 310 to rotate, and the rotation of the bidirectional conical roller 310 drives another fixed rod 39 to rotate, and the rotation of the other fixed rod 39 drives the other through The filter barrel 33 rotates, and after the filtered water flows out of the fixed pipe 32, the filtered water enters the interior of the filter barrel 33 through the bidirectional conical roller 310 for secondary filtration, and some of the filtered water that has not entered the filter barrel 33 falls on the filter mesh 311 for filtration. Finally, the filtered water enters the base 13 and is finally discharged from the interior of the equipment, thereby achieving the purpose of solid-liquid separation of aluminum oxide and water. After completing the primary separation of aluminum oxide and water, a small amount of aluminum oxide will be mixed in the water, and secondary filtration and separation of the aluminum oxide can ensure the separation effect. At the same time, it can also avoid the phenomenon of a large amount of aluminum oxide not being separated and being wasted, thereby reducing costs. In the subsequent wastewater treatment, it can also ensure that the purity of aluminum oxide in the water is reduced, and it is easier to treat wastewater, further ensuring the solid-liquid separation effect of aluminum oxide and water.
