[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figure 1 - Figure 2, An embodiment provided by the present utility model: A powder storage bin, including a bin body 1, a feed inlet 11 is provided at the top of the bin body 1. The feed inlet 11 is located at the top of the bin body 1 and is used to add fly ash into the bin body 1. A discharge port 12 is provided at the bottom surface of the bin body 1. The discharge port 12 is located at the bottom of the bin body 1 and is used to carry out the next use or processing of the treated powder fly ash. A plurality of groups of support legs 2 distributed in an array are fixedly connected to the outer wall of the bin body 1. The support legs 2 are used to provide structural support to ensure the stability of the bin body 1. A plurality of groups of arc-shaped plates 3 distributed in an array are fixedly connected to the inner wall of the bin body 1. A stirring assembly 4 and a filtering assembly 5 are arranged inside the bin body 1. The stirring assembly 4 is used to cut and stir the stored fly ash to prevent the fly ash from caking. The filtering assembly 5 is used to filter the cut fly ash to ensure the use requirements of the fly ash.

[0031] Refer to Figure 2 - Figure 3 , The stirring assembly 4 includes a rotating shaft 41. The rotating shaft 41 penetrates and is rotatably connected to the surface of the bin body 1. A motor 42 is fixedly connected to the top of the bin body 1. The output shaft of the motor 42 is fixedly connected to the end of the rotating shaft 41. The rotating shaft 41 serves as the main shaft of the entire stirring assembly 4. Driven by the motor 42, the rotating shaft 41 can rotate, thereby driving the rotating shaft 41 to rotate. A plurality of groups of crushing blades 43 distributed in an array are fixedly connected to the outer wall of the rotating shaft 41. The crushing blades 43 cut and stir the fly ash through the rotation of the rotating shaft 41. A cross bar 44 is fixedly connected to the outer wall of the rotating shaft 41. A sliding rod 45 is slidably connected to the end of the cross bar 44. The cross bar 44 serves as a support structure. The end of the cross bar 44 is connected to the sliding rod 45 in a sliding connection manner, allowing the sliding rod 45 to move relatively thereon. The sliding rod 45 is elastically connected to the inner wall of the cross bar 44 through a return spring 46. A scraping plate 47 is fixedly connected to the end of the sliding rod 45. The return spring 46 is used to elastically support the sliding rod 45, so that the scraping plate 47 fits against the inner wall of the bin body 1. As the rotating shaft 41 rotates, the scraping plate 47 cleans the inner wall of the bin body 1 to prevent fly ash from adhering to the inner wall of the bin body 1. And during the rotation of the scraping plate 47, it is pressed against the arc-shaped plate 3, causing the return spring 46 to be compressed. After the scraping plate 47 is misaligned with the arc-shaped plate 3, the return spring 46 drives the scraping plate 47 to return to its original position and knocks on the inner wall of the bin body 1 to improve the cleaning effect. A limiting groove 48 is provided on the side wall of the cross bar 44. A limiting block 49 is slidably connected to the inside of the limiting groove 48. The limiting block 49 is fixedly connected to the side wall of the sliding rod 45. The limiting groove 48 and the limiting block 49 are used to limit and guide the sliding rod 45, making the sliding rod 45 more stable during movement. A curved plate 410 is fixedly connected to the side wall of the scraping plate 47. The curved plate 410 rotates as the scraping plate 47 rotates and simultaneously cleans the surface of the filter plate 51.

[0032] Refer to Figure 2 , Figure 4, the filtering component 5 includes a filter plate 51 which is slidably connected to the inner wall of the bin body 1. The filter plate 51 is used to filter the fly ash, allowing fine fly ash particles to pass through while retaining larger fly ash above, and then crushing it again through the stirring component 4. A plurality of sets of triangular plates 52 distributed in an array are fixedly connected to the surface of the filter plate 51. The triangular plates 52 are used to press the curved plate 410, causing the filter plate 51 to move downward. Through holes are formed through the surface of the filter plate 51, and the inner wall of the through hole is slidably connected to the rotating shaft 41. Two convex blocks 53 are fixedly connected to the inner wall of the bin body 1. The two convex blocks 53 are fixedly connected to a guide rod 54. The guide rod 54 passes through and is slidably connected to the surface of the filter plate 51. The two convex blocks 53 are used to fix and support both ends of the guide rod 54, and the guide rod 54 is used to guide and position the filter plate 51, enabling the filter plate 51 to move up and down stably. The convex block 53 and the bottom surface of the filter plate 51 are elastically connected by a support spring 55. The support spring 55 is used to provide elastic support for the filter plate 51, so that during the downward movement of the filter plate 51, the support spring 55 enables the filter plate 51 to quickly return to its original position and causes the filter plate 51 to vibrate slightly, accelerating the discharging during filtration.

[0033] Working principle: Start the motor 42. The output shaft of the motor 42 drives the rotating shaft 41 to rotate, causing the rotating shaft 41 to drive the crushing blades 43 to cut and stir the fly ash to prevent the fly ash from caking. At the same time, the rotating shaft 41 drives the cross bar 44 and the sliding rod 45 to rotate, causing the scraper 47 to clean the inner wall of the bin body 1 to prevent the fly ash from adhering to the inner wall of the bin body 1. And during the rotation of the scraper 47, it is pressed against the arc plate 3, causing the return spring 46 to be compressed. After the scraper 47 and the arc plate 3 are misaligned, the return spring 46 drives the scraper 47 to return to its original position and knock on the inner wall of the bin body 1 to improve the cleaning effect. The curved plate 410 rotates along with the rotation of the scraper 47 and simultaneously cleans the surface of the filter plate 51. At the same time, the scraper 47 presses against the triangular plate 52, causing the filter plate 51 to move downward and compressing the support spring 55, allowing fine fly ash particles to pass through the filter plate 51 while retaining larger fly ash above and crushing it again through the stirring component 4. The support spring 55 enables the filter plate 51 to quickly return to its original position and causes the filter plate 51 to vibrate slightly, accelerating the discharging during filtration and realizing continuous discharging.
