Description

Technical Field

[0001] The utility model relates to the technical field of alumina separation, in particular to a high-temperature alumina separation device. Background Art

[0002] High-temperature alumina generally refers to the stable alumina crystal form formed by calcination at high temperature (usually ≥ 1200 °C), specifically α-alumina (α-Al2O3). It is the final stable form of alumina (Al2O3) at high temperature, and has characteristics such as high purity, high hardness, high temperature resistance and chemical inertness, and is widely used in high-temperature or harsh environment fields such as refractory materials, ceramics, and electronic components. In order to ensure the quality of high-temperature alumina, a separation device is usually used for separation treatment.

[0003] After retrieval, an alumina powder separation device with the authorization announcement number of CN219309251U injects alumina powder into the inside of the feed pipe to enter the inside of the stirring barrel. When the stirring barrel rotates, the alumina powder inside it will enter the inside of the collection frame and the aggregate frame through the first filter screen and the second filter screen respectively, so as to complete the screening work of the alumina powder and facilitate the collection of the alumina powder.

[0004] However, after the device completes the screening of alumina, the unqualified alumina will be crushed and discharged. Since these discharged alumina need to be manually collected and poured into the device for secondary separation, this process is relatively labor-intensive and increases the labor intensity of workers.

[0005] Therefore, it is necessary to provide a high-temperature alumina separation device to solve the above technical problems. Summary of the Utility Model

[0006] To solve the technical problem that the existing separation device requires manual collection and pouring into the device for secondary separation after crushing the unqualified alumina, resulting in a relatively labor-intensive process and increasing the labor intensity of workers, the utility model provides a high-temperature alumina separation device.

By using an electric push rod, the annular cover can be driven to move vertically through a support block, so that the annular cover can release the shielding around the conical screen. After being released, the high-temperature alumina remaining at the top of the conical screen will slide around and fall to the bottom of the shell. By using a crushing mechanism, the high-temperature alumina falling to the bottom of the shell can be crushed, and these high-temperature alumina with unqualified particle size can be crushed into qualified particle size.

[0022] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appearing in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] An embodiment of the present utility model provides a high-temperature alumina sorting device, as Figures 1-4 shown. The high-temperature alumina sorting device includes: a housing 1, a plurality of support rods 2 are fixedly installed on the inner wall of the housing 1, the same cylinder 3 is fixedly installed on the plurality of support rods 2, a discharge pipe 4 is fixedly installed on the cylinder 3, and one end of the discharge pipe 4 extends to the outside of the housing 1; a conical screen 5 fixedly installed on the top of the cylinder 3 for sorting high-temperature alumina; an electric push rod 6 fixedly installed on the inner wall of the top of the housing 1, a support block 7 is fixedly installed on the output rod of the electric push rod 6, a ring cover 8 is fixedly installed on the support block 7, the inner wall of the ring cover 8 is in contact with the cylinder 3, and the ring cover 8 is located outside the conical screen 5; a ring soft sleeve 9 fixedly installed on the ring cover 8, and the top of the ring soft sleeve 9 is fixedly connected to the inner wall of the top of the housing 1; a feeding mechanism installed on the housing 1 for pushing high-temperature alumina; a crushing mechanism assembled on the housing 1 for crushing high-temperature alumina; a material conveying mechanism installed on the housing 1 for conveying high-temperature alumina.

[0024] In this embodiment, when using this device to sort high-temperature alumina, it is necessary to pour the high-temperature alumina to be sorted from the top of the device into the annular cover 8, so that the high-temperature alumina accumulates on the top of the conical screen 5. Then, start the feeding mechanism. The feeding mechanism will push the high-temperature alumina to move on the conical screen 5, so that the high-temperature alumina with qualified particle size can pass through the mesh holes of the conical screen 5 and fall into the cylinder body 3, and finally be discharged from the discharge pipe 4 for collection using a container. The high-temperature alumina with unqualified particle size will remain on the top of the conical screen 5. When the discharge pipe 4 can no longer discharge qualified high-temperature alumina, start the electric push rod 6. The electric push rod 6 will drive the annular cover 8 to move upward through the support block 7, so that the annular cover 8 releases the occlusion around the conical screen 5. After the release, the high-temperature alumina remaining on the top of the conical screen 5 will slide down around and fall to the bottom of the housing 1. During this process, it is necessary to start the crushing mechanism to crush the high-temperature alumina that has fallen to the bottom of the housing 1. After the crushing process, start the electric push rod 6 to drive the annular cover 8 to move downward, so that the annular cover 8 occludes the periphery of the conical screen 5. After the occlusion, start the feeding mechanism, and then the crushed high-temperature alumina can be quickly transported into the annular cover 8, so that the device can sort these high-temperature alumina again. This process does not require manual operation by workers, which can save the physical strength of workers and is relatively convenient to use.

[0025] In a further preferred embodiment of the present utility model, the feeding mechanism includes: a rotating shaft 10 rotatably installed on the housing 1, a pushing plate 11 fixedly installed at the bottom end of the rotating shaft 10, and the pushing plate 11 is in contact with the conical screen 5; a first motor 12 fixedly installed on the top of the housing 1, and the output shaft of the first motor 12 is connected to the rotating shaft 10 through a first coupling.

[0026] In this embodiment, the feeding mechanism is used to push high-temperature alumina. During operation, the first motor 12 will drive the rotating shaft 10 to rotate through the first coupling, and the rotating shaft 10 will drive the pushing plate 11 to rotate, so that the pushing plate 11 can push the high-temperature alumina to move on the conical screen 5, so that the high-temperature alumina with qualified particle size can pass through the mesh holes of the conical screen 5 and fall into the cylinder body 3, and finally be discharged from the discharge pipe 4 for collection using a container. The high-temperature alumina with unqualified particle size will remain on the top of the conical screen 5, thus realizing the sorting work of high-temperature alumina.

[0027] In a further preferred embodiment of the present utility model, the crushing mechanism includes: a connecting rod 13 rotatably installed on the housing 1, and a plurality of crushing knives 15 fixedly installed on the connecting rod 13; a second motor 14 fixedly installed on one side of the housing 1, and the output shaft of the second motor 14 is connected to the connecting rod 13 through a second coupling.

[0028] In this embodiment, the crushing mechanism is used to crush high-temperature alumina. During operation, the second motor 14 drives the connecting rod 13 to rotate through the second coupling. The connecting rod 13 drives a plurality of crushing knives 15 to rotate, and crushes the high-temperature alumina with unqualified particle size falling to the bottom of the housing 1, so that these high-temperature aluminas with unqualified particle size can be crushed into qualified particle sizes.

[0029] In a further preferred embodiment of the present invention, the material conveying mechanism includes: a screw conveyor 16 fixedly installed on the housing 1, a through pipe 17 fixedly installed on the screw conveyor 16, and one end of the through pipe 17 extends into the housing 1; a discharge pipe 18 fixedly installed on the screw conveyor 16, and one end of the discharge pipe 18 extends into the housing 1.

[0030] In this embodiment, the material conveying mechanism is used to convey high-temperature alumina. After the high-temperature alumina with unqualified particle size is crushed, the screw conveyor 16 can be started. The screw conveyor 16 is a prior art, and its principle will not be described. During its operation, the crushed high-temperature alumina enters the screw conveyor 16 through the through pipe 17, so that the high-temperature alumina continuously moves upward and finally is discharged from the discharge pipe 18 into the annular cover 8, enabling the device to re-sort these high-temperature aluminas. This process does not require manual operation by workers and can save the physical strength of workers.

[0031] In a further preferred embodiment of the present invention, the push plate 11 is arranged in a V shape, and a plurality of the crushing knives 15 are all made of stainless steel material.

[0032] In this embodiment, the V-shaped designed push plate 11 can effectively fit on the surface of the conical screen 5 and can well push the high-temperature alumina to move on the conical screen 5. The crushing knives 15 made of stainless steel material have good corrosion resistance and durability and have a good service life.

[0033] In a further preferred embodiment of the present invention, a hopper 19 is fixedly installed on the top of the housing 1, and the inner walls of the bottoms of the cylinder 3 and the housing 1 are both inclined.

[0034] In this embodiment, by using the hopper 19, it is convenient for workers to pour the high-temperature alumina to be sorted into the annular cover 8 from the top of the device. By setting the inner walls of the bottoms of the cylinder 3 and the housing 1 to be inclined, the high-temperature alumina can be discharged more fully and the residue can be reduced.

[0035] In a further preferred embodiment of the present invention, a support frame is fixedly installed at the bottom of the housing 1, and the annular soft sleeve 9 is made of rubber material.

[0036] In this embodiment, by using the support frame, the entire device can be stably supported on the ground for use. The annular soft sleeve 9 made of rubber material has good deformation ability, enabling the electric push rod 6 to smoothly drive the annular cover 8 to move vertically.

[0037] In summary, compared with the related art, in this solution, by using the feeding mechanism, the high-temperature alumina poured into the annular cover 8 can be pushed, enabling the high-temperature alumina to move on the conical screen 5. The high-temperature alumina with qualified particle size can pass through the mesh holes of the conical screen 5 and fall into the cylinder body 3, and finally be discharged from the discharge pipe 4 for collection by a container. The high-temperature alumina with unqualified particle size will remain at the top of the conical screen 5. By using the electric push rod 6, the annular cover 8 can be driven to move vertically through the support block 7, so that the annular cover 8 can release the occlusion around the conical screen 5. After the release, the high-temperature alumina remaining at the top of the conical screen 5 will slide downwards in all directions and fall to the bottom of the housing 1. By using the crushing mechanism, the high-temperature alumina falling to the bottom of the housing 1 can be crushed, and these high-temperature alumina with unqualified particle size can be crushed into qualified particle size. By using the material conveying mechanism, the crushed high-temperature alumina can be quickly transported into the annular cover 8, enabling the device to re-sort these high-temperature alumina. This process does not require manual operation by workers, effectively solving the technical problem that in the existing sorting device, after crushing the unqualified alumina, it is necessary to manually collect and pour it into the device for secondary sorting, resulting in a more laborious process and increasing the labor intensity of workers.

[0038] In several embodiments provided by the present application, it should be understood that the disclosed device can be implemented in other ways.
