[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-primary color phosphors, functional single crystals, precision instruments and aviation functional devices.

[0003] Specifically, in the production process of alumina, the alumina powder produced by the tunnel kiln is severely agglomerated, so the alumina agglomerates need to be crushed and screened to obtain dispersed alumina powder for convenient impurity removal. However, when crushing and screening alumina agglomerates, the two steps are usually performed separately, and it is difficult to crush and screen the alumina agglomerates at one time. Therefore, the alumina material needs to be frequently turned over and transported, resulting in low efficiency in crushing and screening the alumina agglomerates. Utility Model Content

[0033] See also Figures 1-9As shown, the utility model provides an alumina agglomerate crushing and screening device, including a base 4, a material receiving box 5, a storage barrel 2 and an L-shaped mounting base 1.

The mounting holes 3010 are vertically connected to the corresponding matching grooves 309, and the mounting holes 3010 are horizontally coaxial with the corresponding limiting holes 3012. The mounting holes 3010 are coaxially slidably matched with the limiting rods 3011 in the transverse direction, and the inner ends of the limiting rods 3011 at the two side positions close to each other are transversely slidably matched with the corresponding limiting holes 3012, and the outer ends of the limiting rods 3011 at the two side positions, which are away from each other, extend outward from the outer end faces of the corresponding fixing sleeves 303 and are coaxially fixed with handles 304. The portion of the limiting rod 3011 located between the corresponding handles 304 and the outer end faces of the fixing sleeve 303 is coaxially fitted with a spring 305, and the two ends of the spring 305 are respectively fixedly connected to the corresponding handles 304 and the outer end faces of the fixing sleeve 303. The purpose of this arrangement is to enable the storage barrel 2 to rise to the stirring rod 602 and the material diverter plate 60 by vertically extending the telescopic rod body 306. 4 is located in the material storage barrel 2, and the material storage barrel 2 can be detachably fixed to the top of the telescopic rod body 306 by means of vertical sliding cooperation between the matching seat 308 and the matching groove 309 and horizontal sliding cooperation between the limiting rod 3011 and the limiting hole 3012. The material storage barrel 2 can be lowered to separate from the stirring rod 602 and the material stripping plate 604 of the mixing and crushing assembly 6 by vertically retracting the telescopic rod body 306. After that, it is only necessary to pull out the limiting rod 3011 to disengage from the limiting hole 3012, so that the matching seat 308 can be vertically slid out of the matching groove 309 to detach the material storage barrel 2 from between the tops of the telescopic rod body 306 at both sides. The fixing combination and disassembly method of the material storage barrel 2 between the tops of the telescopic rod body 306 at both sides are simple and easy to operate.

[0034] See also Figure 1-Figure 5 As shown, an inverted L-shaped mounting seat 1 is fixedly installed on the rear part of the top surface of the base 4, the horizontal part of the top of the L-shaped mounting seat 1 extends forward to above the storage barrel 2 and a vertically arranged mixing and crushing component 6 is fixedly installed on the top surface, and the lower part of the mixing and crushing component 6 extends into the interior of the storage barrel 2. Specifically, the mixing and crushing component 6 includes a driving motor 601 and a sleeve 603. The driving motor 601 is vertically fixed to the front of the top of the L-shaped mounting seat 1, and the motor shaft 605 at the bottom of the driving motor 601 passes through the L-shaped mounting seat 1 in a vertical sliding fit and is coaxial with the center of the storage barrel 2. The bottom end of the motor shaft 605 is coaxially fixed with a stirring shaft 606 through a coupling. The stirring shaft 606 is located inside the storage barrel 2 and A sleeve 603 is coaxially fixed on the periphery, and a plurality of material-dispensing plates 604 are fixed to the outer lower portion of the sleeve 603 extending radially outward, and a plurality of stirring rods 602 are fixed to the outer upper portion of the sleeve 603 extending radially outward. The purpose of such a setting is that the sleeve 603 can be driven to rotate by the driving motor 601, so that the sleeve 603 can drive the stirring rods 602 at the upper portion of the periphery and the material-dispensing plates 604 at the lower portion of the periphery to rotate at the same time, and then the aluminum oxide lumps in the storage barrel 2 can be crushed by the rotation of the stirring rods 602, and the crushed aluminum oxide material can be dropped and screened out through the sieve hole 201 by the rotation of the material-dispensing plates 604, thereby realizing a one-time crushing and splitting operation of the aluminum oxide lumps.

[0035] See also Figure 1-Figure 5 As shown, the quick-release support assembly 3 is optimized as follows: the telescopic rod body 306 is a double-section pull-out telescopic rod with a locking screw 307, and the top surface of the wing seat 302 is installed with a handle 301 for easy handholding. Such a setting first facilitates the telescopic rod body 306 to achieve vertical reciprocating telescopic adjustment by pulling, and at the same time, by providing the handle 301, it is also convenient to hold and drive the storage barrel 2 to perform vertical lifting activities. Further, optionally, the horizontal cross-section shapes of the mating seat 308 and the mating groove 309 are both rectangular, and the mating groove 309 are all blind grooves in the vertical direction, and the bottom ends of the mating seats 308 are in contact with the bottom ends of the corresponding mating grooves 309. With this arrangement, first of all, it is convenient for the mating seats 308 and the mating grooves 309 to have a good positioning and guiding design when they slide vertically. At the same time, in the process of the mating seat 308 sliding vertically along the mating groove 309, when the limiting hole 3012 slides vertically with the mating seat 308 to be horizontally coaxial with the limiting rod 3011, an obvious prompt can be given by the bottom ends of the mating seat 308 being in contact with the bottom ends of the corresponding mating grooves 309.

[0036] See also Figure 1-Figure 5As shown, the mixing and crushing component 6 and the material receiving box 5 are optimized as follows. Specifically for the mixing and crushing component 6, the material stripping plates 604 are all rectangular long strips, and the bottom surfaces of the material stripping plates 604 are close to the inner bottom surface of the storage barrel 2. At the same time, the outer ends of the material stripping plates 604 are close to the inner periphery of the storage barrel 2. This arrangement facilitates the rotation of the material stripping plates 604 to drive the alumina material at the bottom of the storage barrel 2 to be smoothly screened by the sieve holes 201. At the same time, the optional stirring rods 602 are all round rods, and the outer ends of the stirring rods 602 are close to the inner periphery of the storage barrel 2. The stirring rods 602 are evenly distributed vertically and circumferentially. This arrangement facilitates the rotation of the stirring rods 602 to break up the alumina lumps in the storage barrel 2.

[0037] Specifically speaking of the material receiving box 5, a box door 501 that can be flipped down to open and flipped up to close is installed on the front of the material receiving box 5 through a hinge. This arrangement makes it easy to open the box door 501 and smoothly take out the alumina material collected in the material receiving box 5. At the same time, it is easy to take out and put back the storage bucket 2 from the front of the material receiving box 5.

[0038] With the above structure, specifically in the process of crushing and screening alumina lumps, the alumina lumps are placed in the storage barrel 2, the driving motor 601 is electrically connected to the external power supply cable, the driving motor 601 drives the stirring shaft 606 to rotate through the motor shaft 605, and the stirring shaft 606 drives the sleeve 603 to rotate during the rotation, so that the driving motor 601 of the mixing and crushing component 6 drives the sleeve 603 to rotate, which can make the sleeve 603 drive the stirring rod 602 at the upper part of the periphery and the material-diverting plate 604 at the lower part of the periphery to rotate at the same time, and then the stirring rod 602 can be rotated. The alumina agglomerates in the storage barrel 2 are crushed, and at the same time, the crushed alumina materials can be dropped and screened out through the sieve hole 201 by the turnover of the material-dispensing plate 604, thereby realizing a one-time crushing and splitting operation of the alumina agglomerates, without the need for frequent turnover and transportation of the alumina materials, which is beneficial to improving the crushing and screening efficiency of the alumina agglomerates. Specifically, when the storage barrel 2 is used, the telescopic rod body 306 is vertically extended outward and locked by tightening the locking screw 307, so that the storage barrel 2 can be raised until the stirring rod 602 and the material-dispensing plate 604 are located in the storage barrel 2, and at the same time, the mating seat 308 is engaged. The material storage bucket 2 can be detachably fixed to the top of the telescopic rod body 306 by means of vertical sliding cooperation with the cooperation groove 309 and horizontal sliding cooperation with the limiting rod 3011 and the limiting hole 3012. The fixing combination of the material storage bucket 2 between the tops of the telescopic rod body 306 at both sides is simple and easy to operate, and then the material storage bucket 2 is conveniently combined between the tops of the telescopic rod body 306 at both sides and then raised to the mixing and crushing assembly 6 for crushing and screening of alumina agglomerates. After the subsequent crushing and screening of the alumina agglomerates is completed, the material storage bucket 2 can be lowered by vertically retracting the telescopic rod body 306. After the stirring rod 602 and the material stripping plate 604 of the mixing and crushing assembly 6 are separated, it is only necessary to hold the handles 304 on both sides and pull them outwards, and the limit rods 3011 are pulled out of the limit holes 3012 by the stretching of the springs 305. Then, the matching seat 308 can be slid vertically out of the matching groove 309 to remove the storage barrel 2 from between the tops of the telescopic rod bodies 306 on both sides. The method of separating the storage barrel 2 between the tops of the telescopic rod bodies 306 on both sides is simple and easy to operate, and then it is convenient to open the box door 501 of the material receiving box 5 after the storage barrel 2 is disassembled and take it out for thorough cleaning and maintenance of the interior.
