[0003] CN216705048U discloses a high-temperature processing device for the production of ceramic alumina powder. This device addresses the shortcomings of current alumina powder production processes, which typically require heating to remove moisture and then filtering and sieving the powder after heating, resulting in cumbersome operations. Through the coordinated operation of a motor, connecting shaft, rolling contact between a cam and a sliding plate, a return spring, an inclined filter plate, an inclined guide plate, a hot air blower, an air duct, an air outlet, a large pulley, a small pulley and belt drive, a rotating shaft, and multiple stirring shafts, the device can simultaneously perform filtration, sieving, and heating of alumina powder, thus improving the production efficiency of ceramic alumina powder.

[0004] However, the filter plate does not have a structure for cleaning the filter plate. During use, some ceramic alumina powder particles with the same pore size as the filter plate are easily stuck in the pores, causing pore blockage and affecting the screening effect of the filter plate. Therefore, a high-temperature processing device for the production of ceramic alumina powder is proposed to solve the above problems. Utility Model Content

It has the advantages of good screening effect and easy filter pore blockage. It solves the problem that existing high-temperature processing devices for ceramic alumina powder production do not have a structure for cleaning the filter plate. During use, some ceramic alumina powder particles with the same pore size as the filter plate are easily stuck in the filter pores, causing filter pore blockage and affecting the screening effect of the filter plate.

[0006] To achieve the above-mentioned good screening effect and easy clogging of filter holes, this utility model provides the following technical solution: a high-temperature processing device for the production of ceramic alumina powder, including a high-temperature heating box, a screening box on the high-temperature heating box, a screening filter screen inside the screening box, and a cleaning component between the screening box and the screening filter screen; The cleaning assembly includes two connecting shells fixedly installed on the inner surface of the screening box.

The screening filter screen is fixedly installed between the opposite surfaces of the two connecting shells. A heating rod is fixedly installed inside the high-temperature heating box.

[0007] Furthermore, the scraper has an inclined surface and its bottom contacts the upper surface of the sieve filter screen, the rotating roller contacts the lower surface of the sieve filter screen, and the top pillars are multiple and evenly distributed on the surface of the rotating roller. The position of the top pillars corresponds to the aperture of the sieve filter screen surface, and the diameter of the top pillars is smaller than the inner diameter of the sieve apertures on the sieve filter screen surface.

[0008] Furthermore, the opening of the connecting shell faces the bottom of the screening box.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6This embodiment provides a high-temperature processing device for the production of ceramic alumina powder, comprising a high-temperature heating chamber 1, a sieving chamber 2 on the high-temperature heating chamber 1, a sieving filter 3 inside the sieving chamber 2, a cleaning assembly 4 between the sieving chamber 2 and the sieving filter 3, the cleaning assembly 4 comprising two connecting shells 41 fixedly installed on the inner surface of the sieving chamber 2, a connecting frame 42 slidably sleeved on the surface of the connecting shell 41, a scraper 43 and a rotating roller 44 on the surface of the connecting frame 42, a top column 45 fixedly installed on the surface of the rotating roller 44, a driving assembly 10 between the connecting shells 41 and the connecting frame 42, the sieving filter 3 fixedly installed between the opposite surfaces of the two connecting shells 41, and a heating rod 5 fixedly installed inside the high-temperature heating chamber 1.

[0019] In this embodiment, the surface of the scraper 43 is inclined and its bottom is in contact with the upper surface of the sieve filter 3, the rotating roller 44 is in contact with the lower surface of the sieve filter 3, and there are multiple top pillars 45 evenly distributed on the surface of the rotating roller 44. The position of the top pillars 45 corresponds to the aperture of the sieve filter 3, and the diameter of the top pillars 45 is smaller than the inner diameter of the sieve holes on the surface of the sieve filter 3.

[0020] In this embodiment, the opening of the connecting shell 41 faces the bottom of the screening box 2.

[0021] In this embodiment, the drive assembly 10 includes a drive motor 101 fixedly installed on one end surface of the connecting shell 41. A threaded rod 102 that penetrates into the connecting shell 41 is fixedly installed at the output end of the drive motor 101. A threaded cylinder 103 is fixedly installed on the inner side of the connecting frame 42. The threaded cylinder 103 and the threaded rod 102 are threadedly connected. By setting the drive assembly, it is convenient to drive the scraper 43 and the rotating roller 44 to move.

[0022] In this embodiment, a limiting block 421 is fixedly installed on the inner side of the connecting frame 42. The limiting block 421 slides in contact with the inner side of the connecting shell 41. The limiting block 421 facilitates the limiting of the connecting shell 41.

[0023] In this embodiment, the screening box 2 is connected to the interior of the high-temperature heating box 1, and the top of the screening box 2 is fixedly equipped with a feeding port 6 that is connected to the screening box 2 and located directly above the screening filter screen 3.

[0024] In this embodiment, a rectangular opening 7 is provided on one side surface of the screening box 2, and a guide plate 8 is fixedly installed at an angle inside the rectangular opening 7. A collection frame 9 is placed on the upper surface of the high-temperature heating box 1. One end of the guide plate 8 is located directly below the screening filter screen 3 and the other end is located directly above the collection frame 9, which facilitates the collection of unqualified powder particles.

[0025] In this embodiment, the bottom surface of the inner cavity of the high-temperature heating box 1 is inclined, and the number of heating rods 5 is multiple and evenly distributed at the bottom of the inner cavity of the high-temperature heating box 1. A discharge port 11 is provided on one side surface of the high-temperature heating box 1, and the discharge port 11 is located on the lower side of the bottom surface of the inner cavity of the high-temperature heating box 1.

[0026] It should be noted that the length of the top column 45 in this embodiment is less than the thickness of the sieve filter screen 3.

[0027] The working principle of the above embodiments is as follows: During use, the operator feeds the alumina powder to be processed into the screening box 2 through the feeding port 6. The powder falls directly onto the screening screen 3. Powder smaller than the aperture of the screening screen 3 passes through the screen holes and falls into the high-temperature heating box 1 below; while powder larger than the aperture of the screening screen 3 remains on the upper surface of the screening screen 3, achieving preliminary screening. During the screening process, to prevent the screening screen 3 from clogging, the drive motor 101 is started, and its output end drives the threaded rod 102 to rotate. Since the threaded cylinder 103 is threadedly connected to the threaded rod 102, and the limiting block 421 on the inner side of the connecting frame 42 slides in contact with the inner side of the connecting shell 41, it limits the connecting frame 42, allowing the connecting frame 42 to slide linearly along the surface of the connecting shell 41. As the connecting frame 42 slides, the scraper 43 and the rotating roller 44 also move. When the rotating roller 44 moves with the connecting frame 42, the top column 4... 5 will be inserted into the sieve hole to push out the ceramic alumina powder particles stuck in the sieve hole. The scraper 43 will scrape off the powder accumulated on the upper surface of the sieve filter 3 and the cleaned particles. The qualified powder that passes through the sieve filter 3 and falls into the high temperature heating box 1 will be heated by the heating rod 5 in the high temperature heating box 1. After high temperature processing, the powder will converge towards the discharge port 11 under the action of gravity because the bottom surface of the inner cavity of the high temperature heating box 1 is inclined. The workers can discharge the processed powder through the discharge port 11. The unqualified powder left on the upper surface of the sieve filter 3 will be scraped by the scraper 43 during the cleaning process. It will slide from the rectangular opening 7 on one side of the sieve box 2 through the guide plate 8 that is inclined and fixed inside the rectangular opening 7 into the collection frame 9 placed on the upper surface of the high temperature heating box 1, so as to collect the unqualified powder and facilitate subsequent processing.
