Description

Technical Field

[0001] This utility model relates to the field of alumina processing technology, and more specifically to an alumina coarse material filtration device. Background Technology

[0002] Alumina, as an important industrial raw material, is widely used in many fields such as ceramics, refractory materials, abrasive products, catalyst carriers and advanced ceramics. In its production process, it is usually necessary to filter the alumina slurry (a slurry containing a large amount of water and impurities, and primary alumina crystals), that is, to separate the alumina slurry into solid and liquid components, in order to obtain pure alumina products or to carry out subsequent fine processing.

[0003] Currently, in laboratory research and development or small-scale testing, traditional small-scale filtration devices are commonly used for separation operations. However, in actual production applications, alumina coarse slurry can easily cause severe clogging of the micropores of the filter medium in the filtration device. The clogging problem directly leads to a significant increase in filtration resistance and a sharp decrease in the effective filtration area, which in turn causes a significant drop in filtration efficiency. In severe cases, the filtration device may even completely lose its separation function, forcing the production or experimental process to be interrupted. Utility Model Content

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Reference Figures 1-4 This utility model provides an alumina coarse material filtration device, including a support frame 8. A rotating plate 3 is hinged to the top of the extended end of the support frame 8 and mounted at an angle. A second housing 10 is rotatably mounted on the lower surface of the rotating plate 3 via bearings. A detachable first housing 1 is located at the bottom of the second housing 10. Multiple evenly distributed leakage holes 11 are formed at the bottom conical surface of the first housing 1. A power assembly 9 for driving the second housing 10 to rotate is located on the lower surface of the rotating plate 3. The power assembly 9 includes a cavity 901 formed on the lower surface of the rotating plate 3. A toothed ring 903 is bolted to the top of the second housing 10 and located within the cavity 901. 03 is coaxial with the second housing 10. A gear 902 that meshes with the gear ring 903 is provided in the cavity 901. A servo motor that drives the gear 902 to rotate along the axis is fixed to the upper surface of the rotating plate 3 by bolts. An anti-clogging component 2 for the leakage hole 11 is provided in the rotating plate 3. The anti-clogging component 2 includes an air inlet pipe 201 fixedly connected to one side of the rotating plate 3. One end of the air inlet pipe 201 penetrates the surface of the rotating plate 3. The other end of the air inlet pipe 201 is fixedly connected to a manifold 202. The inclination angle of the manifold 202 is parallel to the conical surface of the first housing 1. Multiple equally spaced nozzles 203 are fixedly connected to the outer side of the manifold 202 near the conical surface of the first housing 1.

[0026] The servo motor is started, which drives the gear 902 to rotate. The gear 902 drives the second housing 10 to rotate through the gear ring 903. The first housing 1 rotates together with the second housing 10. At the same time, the liquid in the alumina slurry is discharged from the drain hole 11 due to gravity, realizing solid-liquid separation. Meanwhile, the air inlet pipe 201 is connected to an external high-pressure air source. The external high-pressure gas enters the manifold 202 through the air inlet pipe 201 and is then sprayed out from multiple nozzles 203. The sprayed gas blows the drain hole 11 on the conical surface of the first housing 1 to prevent impurities in the alumina slurry from clogging the drain hole 11, ensuring the smooth progress of the filtration process. This solves the problem that clogging leads to a significant increase in filtration resistance, a sharp decrease in effective filtration area, and a significant drop in filtration efficiency.

[0027] It should be noted that servo motors are existing technology, and those skilled in the art can set them according to actual needs, which will not be elaborated here.

[0028] In this embodiment, a feed pipe 5 is fixedly connected to the upper surface of the rotating plate 3, and one end of the feed pipe 5 penetrates the surface of the rotating plate 3 and communicates with the interior of the second housing 10. A funnel 4 connected to the feed pipe 5 is fixedly connected to the top end of the feed pipe 5. Alumina coarse material is poured in through the funnel 4 and enters the interior of the second housing 10 through the feed pipe 5. The setting of the funnel 4 increases the area of ​​the feed inlet, making it more convenient and faster to pour in the alumina coarse material, reducing the possibility of material spillage and improving the feeding efficiency.

[0029] In this embodiment, a fixing block 701 is fixedly connected to one side of the support frame 8 near the rotating plate 3. A threaded groove 703 is provided on one side of the rotating plate 3. A screw 702 is inserted into one side of the fixing block 701, and one end of the screw 702 passes through the fixing block 701 and is threadedly connected to the threaded groove 703. A limiting block 704 for supporting the rotating plate 3 is fixedly connected to one side of the support frame 8 near the rotating plate 3. A plurality of evenly distributed latches 13 are provided on the outer circumference of the first housing 1 and the second housing 10. The fixing part of the latches 13 is connected to the second housing 10 by screws. The movable part is fixed to the first housing 1 by bolts. When it is necessary to unload the material, first turn the screw 702 to disengage the screw 702 from the threaded groove 703, then turn the rotating plate 3 to a horizontal position. The rotating plate 3 drives the first housing 1 and the second housing 10 to rotate to a horizontal position. At the same time, the limiting block 704 supports the rotating plate 3. Then the movable part of the latch 13 opens to separate the first housing 1 and the second housing 10. At this time, the alumina coarse material after solid-liquid separation can be smoothly taken out from the second housing 10, completing the unloading operation.

[0030] In this embodiment, a collection box 6 is provided on the upper surface of the support frame 8. The inner diameter of the collection box 6 is larger than the outer diameter of the first housing 1, and the collection box 6 is located directly below the first housing 1. The collection box 6 is used to collect liquids or residual materials that may drip during the separation process from the first housing 1 and the second housing 10, so as to prevent them from scattering into the surrounding environment and causing pollution or inconvenience in cleaning.

[0031] The use of this utility model involves the following steps:

[0032] S1: First, pour the alumina raw material through the funnel 4, and then enter the second shell 10 and the interior of the first shell 1 through the feed pipe 5;

[0033] S2: Then start the servo motor, which drives the gear 902 to rotate. The gear 902 drives the second housing 10 to rotate through the gear ring 903. The first housing 1 rotates together with the second housing 10. At the same time, the liquid in the alumina slurry will be discharged from the drain hole 11 due to gravity, realizing solid-liquid separation. Meanwhile, the air inlet pipe 201 is connected to an external high-pressure air source. The external high-pressure gas enters the manifold 202 through the air inlet pipe 201 and is then sprayed out from multiple nozzles 203. The sprayed gas blows the drain hole 11 on the conical surface of the first housing 1.

[0034] S3: After filtration, first rotate screw 702 to disengage screw 702 from thread groove 703, then rotate rotating plate 3 to a horizontal position. Rotating plate 3 drives the first housing 1 and the second housing 10 to a horizontal position, while limiting block 704 supports rotating plate 3.

[0035] S4: Then the movable part of the latch 13 opens, separating the first housing 1 from the second housing 10. Then the alumina coarse material after solid-liquid separation can be smoothly taken out from the second housing 10, thus completing the unloading operation.
