Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of aluminum ash screening and separation technology, and specifically to a rotary aluminum ash multi-mesh separation and sorting system. Background Technology
[0002] Aluminum ash can be classified into primary aluminum ash and secondary aluminum ash based on its aluminum content. Primary aluminum ash, the aluminum slag scraped from the smelting furnace, is grayish-white in appearance and is mainly a mixture of metallic aluminum and aluminum oxides, with an aluminum content ranging from 15% to 70%. It is also known as "white aluminum ash." Secondary aluminum ash is the waste material after the extraction of metallic aluminum from primary aluminum ash. Its main components are alumina, aluminum nitride, metallic aluminum, salts, and other components. Because it solidifies into lumps, it is also called "salt cake." The composition of aluminum ash varies significantly depending on the production stage and process. The main phases are alumina, metallic aluminum, magnesium aluminum spinel, periclase, quartz, aluminum nitride, aluminum carbide, and salt solvents. During storage, aluminum ash exposed to rain or humid environments releases waste gases such as ammonia, hydrogen, and hydrogen sulfide, and also causes the leaching of heavy metals and fluorides, polluting the environment and posing safety hazards.
[0003] In waste aluminum ash smelting systems, the inconsistent size of the collected waste aluminum ash can easily lead to uneven smelting during the process. Therefore, it is necessary to classify and screen the waste aluminum ash by size before smelting it in groups of similar sizes to achieve uniform smelting. However, current technologies for screening waste aluminum ash are difficult, time-consuming, and labor-intensive. While using a combination of vibrators and springs to vibrate the screen layer and separate the coarse and fine waste aluminum ash effectively separates them, the screening efficiency achieved solely through vibration is low, and incomplete screening is common when dealing with large quantities of aluminum ash.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0021] Please see Figure 1-Figure 5In this embodiment of the present invention, a rotary aluminum ash multi-mesh separation and sorting system includes a support device 10, a primary screening mechanism 20, and a secondary screening mechanism 30. The support device 10 includes a base 11 and a top seat 13. The base 11 is fixedly connected to the top seat 13 by at least one support frame 12. The primary screening mechanism 20 is mounted on the top seat 13, and the secondary screening mechanism 30 is mounted between the base 11 and the top seat 13. The primary screening mechanism 20 includes a movable seat 21 and a screen 22. The movable seat 21 is provided with two rotating mechanisms 23 for controlling the rotation of the screen 22. The rotating mechanism 23 includes a crank 232 and a connecting rod 233. The crank 232 is rotatably mounted on the movable seat 21, and the connecting rod 233 is rotatably mounted on the screen 21. One end of the connecting rod 233 is rotatably mounted on the eccentric part of the crank 232, and the other end of the connecting rod 233 is rotatably connected to the side of the screen 22. The movable seat 21 is also equipped with a rotary motor 231 that controls the rotation of the crank 232. When the rotary motor 231 controls the crank 232 to rotate, the crank 232 drives the screen 22 to rotate through the connecting rod 233. The two rotating mechanisms 23 cooperate with each other, causing the screen 22 to sway on the movable seat 21, thereby screening the aluminum ash loaded into the screen 22 and discharging the aluminum ash that meets the screening requirements from the screen 22. It should be noted that the bottom of the movable seat 21 is provided with a discharge port 211, which is located above the feed side of the secondary screening mechanism 30. The screened aluminum ash enters the secondary screening mechanism 30 from the discharge port 211.
[0022] Furthermore, in this embodiment, the screen 22 is a funnel-shaped structure composed of a screen body 221 and a bottom screen plate 222. The funnel-shaped structure of the screen 22 is conducive to storing aluminum ash and increasing the pressure between the aluminum ash and the screen body 221, thereby improving the screening effect when the screen 22 rotates. The bottom screen plate 222 is detachably installed at the bottom of the screen body 221. After the aluminum ash screening is completed, the bottom screen plate 222 can be removed to collect the aluminum ash that has not passed through the screen 22.
[0023] Furthermore, in this embodiment, the movable seat 21 is slidably mounted on the top seat 13. The top seat 13 is provided with a drive mechanism 14 for controlling the sliding of the movable seat 21. The top seat 13 is also provided with two openings 131. The opening 131 on the right side is used to discharge aluminum ash retained inside the screen 22, and the opening 131 on the left side is opened between the discharge port 211 at the bottom of the movable seat 21 and the feed side of the secondary screening mechanism 30. Figure 1 In the middle, the opening 131 on the left is obscured by the primary screening mechanism 20 and cannot be displayed.
[0024] In this embodiment, the driving mechanism 14 includes an adjusting screw 141, an adjusting sleeve 142, and a control motor 143 that drives the adjusting screw 141 to rotate. The adjusting screw 141 is rotatably mounted on the top seat 13. The adjusting sleeve 142 is threadedly connected to the adjusting screw 141, and one side of the adjusting sleeve 142 is slidably connected to the top seat 13. The other side of the adjusting sleeve 142 is fixedly connected to the movable seat 21. When the adjusting screw 141 rotates, it drives the adjusting sleeve 142 and the movable seat 21 to move, so that the discharge port 211 at the bottom of the movable seat 21 is aligned with the opening 131. When the discharge port 211 at the bottom of the movable seat 21 is aligned with the right opening 131, the bottom screen plate 222 can be removed to collect the aluminum ash that has not passed through the screen 22. When the discharge port 211 at the bottom of the movable seat 21 is aligned with the left opening 131, the aluminum ash that has passed through the screen 22 enters the secondary screening mechanism 30 through the discharge port 211 and the opening 131.
[0025] In this embodiment, the secondary screening mechanism 30 includes an outer shell 39 and an inner cylinder 31 rotatably installed inside the outer shell 39. A frame 33 is installed at the bottom of the inner cylinder 31, and the frame 33 is rotatably connected to the bottom of the outer shell 39. There is a discharge space between the inner cylinder 31 and the outer shell 39. A feed inlet 312 is provided on the upper side of the inner cylinder 31, and a plurality of separation holes 311 are evenly provided on the side wall of the inner cylinder 31. The aluminum ash after being screened by the primary screening mechanism 20 enters the inner cylinder 31 through the feed inlet 312. When the inner cylinder 31 rotates, the aluminum ash enters the discharge space through the separation holes 311 under the action of centrifugal force. A second discharge port 391 is provided at the bottom of the discharge space of the outer shell 39. The second discharge port 391 is used to discharge the aluminum ash screened by the secondary screening mechanism 30.
[0026] The outer shell 39 is fixedly mounted on the base 11, and a drive gear 37 is rotatably mounted on the base 11. A gear ring 34 is fixedly mounted on the bottom of the inner cylinder 31, and the gear ring 34 meshes with the drive gear 37. A drive motor 38 is also mounted on the base 11, and the output end of the drive motor 38 is fixedly connected to the drive gear 37. The drive motor 38 is used to control the rotation of the inner cylinder 31 inside the outer shell 39.
[0027] Furthermore, in this embodiment, the inner cylinder 31 is further provided with a conical top block 32. The bottom of the conical top block 32 is slidably mounted on the inner cylinder 31 via a sliding shaft 35. A mounting bracket is fixedly mounted on the bottom of the inner cylinder 31, and a telescopic component 36 is provided on the mounting bracket. The telescopic end of the telescopic component 36 is fixedly connected to the sliding shaft 35. The telescopic component 36 is used to control the conical top block 32 to slide up and down inside the inner cylinder 31, changing the distance between the conical top block 32 and the inner wall of the inner cylinder 31. The inclined surface of the conical top block 32 is used to squeeze the aluminum ash inside the inner cylinder 31, so that the aluminum ash... The aluminum ash is evenly distributed between the inner wall of the inner cylinder 31 and the conical top block 32, thereby improving the screening efficiency of aluminum ash. The bottom of the inner cylinder 31 is provided with a first discharge port 313, which is used to discharge aluminum ash that has not passed through the separation hole 311. In this embodiment, by setting the screen 22, the first discharge port 313 and the second discharge port 391, the various types of aluminum ash generated during the screening process are classified and discharged, which is conducive to improving the collection efficiency of aluminum ash. In addition, it should be noted that the inner wall of the inner cylinder 31 is inclined, and the inclination angle of the inner wall of the inner cylinder 31 is the same as the inclination angle of the outer wall of the conical top block 32.
[0028] It should also be noted that the screen body 221 and the bottom screen plate 222 have the same screen hole diameter. The screen hole diameter of the screen body 221 is larger than the diameter of the separation hole 311. Multi-level screening and separation of aluminum ash is achieved by setting a multi-mesh screening mechanism (screen 22 and inner cylinder 31).
