Description

Technical Field

[0001] The utility model relates to the field of auxiliary components for preparing aluminum oxide, in particular to an aluminum oxide slurry impurity removal and stirring device. Background Art

[0002] High-purity alumina is an important chemical material in modern industrial production. It has superior optical, thermal, magnetic and mechanical properties that ordinary alumina does not have. It is widely used in the production of integrated circuit substrates, transparent high-pressure sodium lamps, tri-color phosphors, functional single crystals, precision instruments and aviation functional devices. Since the raw materials for alumina production are generally extracted from bauxite, there will be some impurities that directly affect the physical and chemical properties of the finished alumina products. Therefore, it is necessary to remove impurities from the alumina during the preparation stage.

[0003] Specifically, in the process of removing impurities from alumina slurry, it is necessary to remove the impurity iron in the alumina slurry to avoid a high iron content in the finished alumina product. However, at present, when removing impurities from alumina slurry, it is usually done by immersing an electromagnet into the alumina slurry. However, since the electromagnet is in a stationary state after being immersed in the alumina slurry, the removal effect of the impurity iron in the alumina slurry is general and incomplete.

The alumina slurry in the stirring barrel body can be stirred by driving the stirring blades to rotate through the stirring shaft of the material stirring component. Then, the alumina slurry can be continuously contacted with the material impurity removal component through the stirring flow of the alumina slurry. Thus, the alumina slurry can be fully contacted with the annular electromagnet body through the circulation of the alumina slurry to continuously contact the annular electromagnet body, thereby enhancing the removal effect of impure iron. Details are explained below.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0015] The above-mentioned alumina slurry impurity removal and stirring device is used. Specifically, during the process of removing iron impurities from the alumina slurry, the alumina slurry is poured in through the top of the stirring barrel body, and then the drive motor and the annular electromagnet body are powered on by being electrically connected to the external power supply cable respectively. The drive motor drives the stirring shaft to rotate through the motor shaft, and the stirring shaft drives the stirring blades on the periphery of the fixed sleeve to rotate during the rotation.

The annular electromagnet body can be lifted and lowered reciprocally in the alumina slurry, and then the alumina slurry can be further fully contacted with the annular electromagnet body through the reciprocating lifting of the annular electromagnet body, so that the impurity iron in the alumina slurry can be adsorbed and removed by the alumina slurry contacting the annular electromagnet body, which further enhances the removal effect of impurity iron and is beneficial to further improve the removal efficiency of impurity iron.

[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0029] See also Figure 1-Figure 7 As shown, the utility model provides an alumina slurry impurity removal and stirring device, including a stirring barrel body 2, wing seats 201 are horizontally extended and fixed on the top of both sides of the stirring barrel body 2, and a mounting support 1 is fixed across the wing seats 201 at both sides, and a material stirring component 3 for stirring the alumina slurry in the stirring barrel body 2 is fixedly installed in the middle of the mounting support 1, and the material stirring component 3 is coaxial with the center of the stirring barrel body 2. Specifically, the material stirring component 3 includes a driving motor 301 and a stirring shaft 302, the driving motor 301 is vertically fixed in the middle of the top surface of the mounting support 1, and the motor shaft 305 at the bottom of the driving motor 301 passes through the bottom surface of the mounting support 1 in a vertical sliding fit manner and is coaxial with the center of the stirring barrel body 2, and the bottom of the motor shaft 305 A stirring shaft 302 is coaxially fixed to the end through a coupling, and a plurality of fixed sleeves 303 are coaxially fixed to the periphery of the stirring shaft 302, and a plurality of stirring blades 304 are fixed on the periphery of each fixed sleeve 303 extending outward. The purpose of such a configuration is to stir the alumina slurry in the stirring barrel body 2 by driving the stirring blades 304 to rotate through the stirring shaft 302, and then the alumina slurry can be continuously contacted with the material impurity removal component 4 through the stirring flow of the alumina slurry, so that the alumina slurry can be fully contacted with the annular electromagnet body 407 through the circulation of the alumina slurry. The impurity iron in the alumina slurry is adsorbed and removed by the alumina slurry contacting the annular electromagnet body 407.

[0030] See also Figure 1-Figure 3As shown, a material impurity removal component 4 for removing impurity iron from the alumina slurry in the mixing barrel body 2 is installed on the top of the mounting support 1 at a position beside the material stirring component 3, and the lower part of the material impurity removal component 4 is located in the mixing barrel body 2, and the material impurity removal component 4 includes a cylinder body 401 and an annular electromagnet body 407. The top surface of the mounting support 1 is vertically fixed with the cylinder body 401 at a position on one side of the driving motor 301. The telescopic push rod 403 at the bottom of the cylinder body 401 passes through the bottom surface of the mounting support 1 in a vertical sliding fit manner, and the bottom end is fixed to an extension seat 4011 on one side of the top surface of the fixed ring plate 404 through a connecting sleeve 406. Preferably, the outer edges of the extension seat 4011 do not contact the inner wall of the mixing barrel body 2, and the connecting sleeve 406 is welded to the top surface of the fixed ring plate 404, and the telescopic push rod 403 is connected to the connecting sleeve 406. The sleeve 406 is coaxially interference fit, the fixed ring plate 404 is coaxial with the center of the mixing barrel body 2 and the inner circumference does not contact the outer edge of the mixing blade 304, and the bottom surface of the fixed ring plate 404 is coaxially fixedly installed with an annular electromagnet body 407, and the inner circumference of the annular electromagnet body 407 also does not contact the outer edge of the mixing blade 304. The purpose of this arrangement is that the cylinder body 401 drives the fixed ring plate 404 and the annular electromagnet body 407 to move back and forth vertically, so that the annular electromagnet body 407 can move back and forth in the alumina slurry, and then the alumina slurry can be further fully contacted with the annular electromagnet body 407 through the reciprocating lifting of the annular electromagnet body 407, so that the impurity iron in the alumina slurry can be adsorbed and removed by the alumina slurry contacting the annular electromagnet body 407.

[0031] See also Figure 1-Figure 3 As shown, the material stirring component 3 and the material impurity removal component 4 are optimized as follows. Specifically, with respect to the material stirring component 3, the multiple stirring blades 304 of each fixed sleeve 303 are evenly distributed along the circumference, and the stirring blades 304 are all rectangular plates. This arrangement makes it easy for the stirring shaft 302 to drive the stirring blades 304 to efficiently stir the alumina slurry during the turnover process.

[0032] Specifically, as for the material impurity removal component 4, the extension seat 4011 on the other side of the top surface of the fixed ring plate 404 is vertically fixed with a guide rod 4010 through a connecting sleeve 406. Preferably, the outer edge of the extension seat 4011 does not contact the inner wall of the mixing barrel body 2. At the same time, the connecting sleeve 406 is welded to the top surface of the fixed ring plate 404, and the guide rod 4010 and the connecting sleeve 406 are coaxially interference fit. The mounting support 1 is vertically opened with a guide hole 409 at the position on the other side of the drive motor 301, and the top of the guide rod 4010 passes through the guide hole 409 in a vertical sliding fit manner. 9. With such an arrangement, in the process that the telescopic push rod 403 drives the fixed ring plate 404 and the annular electromagnet body 407 to reciprocate and ascend, the vertical ascending and descending of the fixed ring plate 404 and the annular electromagnet body 407 can be guided and corrected by the guide rod 4010 sliding vertically along the guide hole 409. At the same time, the top end of the guide rod 4010 can be coaxially fixed with an anti-drop cap 408 whose outer diameter is larger than the aperture of the guide hole 409, so as to prevent the top end of the guide rod 4010 from accidentally escaping from the bottom end of the guide hole 409 through the arrangement of the anti-drop cap 408. Further optionally, the terminal 405 of the annular electromagnet body 407 extends out of the top surface of the fixed ring plate 404, and the mounting support 1 is provided with a wire passing opening 402 at a position above the terminal 405. Preferably, when the terminal 405 is connected to an external power supply cable, the power supply cable passing through the wire passing opening 402 should be a spring cable, and the spring cable is in a stretched and straightened state when the annular electromagnet body 407 descends to the lowest position, and is in a vertical and unstretched state when the annular electromagnet body 407 rises to the highest position, so that the annular electromagnet body 407 can be powered smoothly by the cable passing through the wire passing opening 402 and being electrically connected to the terminal 405.

[0033] See also Figure 1-Figure 3 As shown, the mixing barrel body 2 is optimized as follows: a plurality of legs 202 for supporting the mixing barrel body 2 are vertically fixed around the bottom surface of the mixing barrel body 2, so that the mixing barrel body 2 can be stably supported by the legs 202. Optionally, a discharge pipe 203 is vertically fixedly connected to the middle of the bottom surface of the mixing barrel body 2, and a valve 204 for controlling opening and closing is fixedly provided on the outside of the discharge pipe 203. With this arrangement, it is convenient to discharge the decontaminated alumina slurry to the outside through the discharge pipe 203. After the alumina slurry is discharged, the annular electromagnet body 407 can be raised to the highest position and then powered off, so that the impurity iron adsorbed by the annular electromagnet body 407 will be scattered at the bottom of the mixing barrel body 2, and the impurity iron scattered at the bottom of the mixing barrel body 2 can be discharged to the outside through the discharge pipe 203 by flushing.

[0034] With the above structure, specifically in the process of removing iron impurities from the alumina slurry, the alumina slurry is poured into the mixing barrel body 2 through the top, and then the driving motor 301 and the annular electromagnet body 407 are powered on by being electrically connected to the external power supply cable, and the driving motor 301 drives the stirring shaft 302 to rotate through the motor shaft 305. The stirring shaft 302 drives the stirring blades 304 on the periphery of the fixed sleeve 303 to rotate during the rotation. In this process, the stirring blades 304 stir the alumina slurry, so that the stirring shaft 302 of the material stirring assembly 3 is electrically connected to the alumina slurry through the agitation shaft 302 of the material stirring assembly 3. The stirring blade 304 is driven to rotate so as to stir the alumina slurry in the stirring barrel body 2, and then the alumina slurry can be continuously contacted with the material impurity removal component 4 through the stirring flow of the alumina slurry, so that the alumina slurry can be fully contacted with the annular electromagnet body 407 through the circulation of the alumina slurry. After the annular electromagnet body 407 is powered on, the alumina slurry can contact the annular electromagnet body 407 to adsorb and remove the impurity iron in the alumina slurry, thereby enhancing the removal effect of the impurity iron. It is beneficial to improve the removal efficiency of impurity iron. At the same time, in the process of removing impurity iron from the alumina slurry, the cylinder body 401 is ventilated by connecting to the external air supply pipeline. The cylinder body 401 can drive the fixed ring plate 404 and the annular electromagnet body 407 to reciprocate and rise and fall in the mixing barrel body 2 by reciprocating and extending the telescopic push rod 403. In this process, the vertical lifting of the fixed ring plate 404 and the annular electromagnet body 407 can be guided and corrected by the guide rod 4010 sliding vertically along the guide hole 409. In this way, the material impurity removal component 4 The cylinder body 401 drives the fixed ring plate 404 and the annular electromagnet body 407 to reciprocate vertically, so that the annular electromagnet body 407 can move up and down reciprocatingly in the alumina slurry, and then the alumina slurry can be further fully contacted with the annular electromagnet body 407 through the reciprocating lifting of the annular electromagnet body 407, so that the impurity iron in the alumina slurry can be adsorbed and removed by the contact of the alumina slurry with the annular electromagnet body 407, thereby further enhancing the removal effect of the impurity iron and being conducive to further improving the removal efficiency of the impurity iron.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
