Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

Figure 7 This diagram illustrates a three-dimensional structure of a fencing and scraper provided in an embodiment of this application.

[0037] Please see Figures 1 to 7 This application provides an aluminum ash conveying device, comprising: a housing 1 having a cavity and a feed inlet 11 communicating with the cavity; a rotating mechanism 2 including a turntable 21 horizontally disposed in the cavity and a power unit 22 for driving the turntable 21 to rotate, the turntable 21 being used to receive the material introduced by the feed inlet 11; a suction pipe 3 extending into the cavity for sucking up the material on the turntable 21 and conveying the material; a scraper 4 disposed in the cavity and abutting against the top of the turntable 21 for scraping off the material retained on the turntable 21; a crushing component 5 disposed at the bottom of the cavity for receiving the material scraped off by the scraper 4 and crushing the material; and a return component 6, the input end of the return component 6 communicating with the discharge port of the crushing component 5, and the output end located above the turntable 21. Specifically, the crushing component 5 uses a small ball mill, and the return component 6 uses a negative pressure fan and a return pipe to pump the crushed aluminum ash onto the turntable via the negative pressure fan.

[0038] In this application, aluminum ash is introduced into the box 1 through the feed inlet 11. The aluminum ash is spread on the turntable 21. The turntable 21 is rotated by the power unit 22. The aluminum ash rotates to the bottom of the suction pipe 3. The suction pipe 3 adsorbs and transports the aluminum ash powder spread on the turntable 21. Some larger particles will remain on the turntable 21 and continue to rotate with the turntable 21. The scraper 4 scrapes the particles remaining on the turntable 21 to the crushing component 5 below for secondary crushing. The material after secondary crushing is returned to the material tray through the return component 6, thus eliminating the need for manual cleaning, saving labor, and ensuring the processing progress of aluminum ash.

[0039] In related technologies, after aluminum ash is sucked away by the suction pipe 3, the residual aluminum dross accumulates. When the aluminum dross accumulates to a certain amount, it will affect the conveying of aluminum ash and may even cause the sucked-away aluminum powder to contain a large number of aluminum dross particles, affecting the subsequent recycling and processing of aluminum ash. Therefore, in order to ensure the processing quality of aluminum ash in the later stages, it is necessary to ensure that the aluminum ash does not contain large aluminum dross particles. This requires regular manual cleaning of the aluminum dross and monitoring of the amount of aluminum dross. If the monitoring is not in place, aluminum dross may be mixed into the aluminum ash. The amount of aluminum dross in aluminum ash is not large. If a separate conveying mechanism is set up to return the residual aluminum dross to the ball mill, the cost will be high and it is not practical. It not only occupies space but also has low utilization rate.

[0040] In this embodiment, aluminum ash is spread on the turntable 21, sucked in and conveyed through the suction pipe 3, and the remaining aluminum slag is scraped by the scraper 4 and sent to the crushing component 5. The crushing component 5 is designed to be small in size and can work continuously, crushing any aluminum slag that enters. The crushing component 5 can also work intermittently, starting again when the amount of aluminum slag in the crushing component 5 reaches a certain level. The crushed aluminum slag is then returned to the turntable 21 through the return component 6, and then waits for the next amount of aluminum slag to be crushed. The structure is simple, and there is no need to set up a large conveying mechanism to transport the aluminum slag. At the same time, there is no need for manual cleaning of the aluminum slag, and it can also ensure that the aluminum ash does not contain particulate aluminum slag, thus ensuring the processing quality of the aluminum ash.

[0041] In some embodiments, a feeding area 211, a suction area 212, and a scraping area 213 are provided above the turntable 21; the feed port 11 and the output end of the return assembly 6 are located in the feeding area 211; the suction port of the suction pipe 3 is located in the suction area 212; and the scraper 4 is located in the scraping area 213.

[0042] In this application, a feeding area 211, a suction area 212, and a scraping area 213 are sequentially arranged along the circumference of the turntable 21. The material passes through the feeding area 211, the suction area 212, and the scraping area 213 sequentially on the turntable 21, ensuring that the suction pipe 3 can fully suck up and transport aluminum ash in the suction area 212.

[0043] In some embodiments, a partition 7 is provided in the cavity, the partition 7 is located above the turntable 21, and there is a gap between the partition 7 and the turntable 21. The partition 7 divides the upper part of the turntable 21 into a feeding area 211, a suction area 212 and a scraping area 213.

[0044] In this application, the partition 7 is set above the turntable 21. The partition 7 separates the feeding area 211, the suction area 212 and the scraping area 213, ensuring that the suction area 212 can generate a large negative pressure suction force, thereby ensuring the suction effect of aluminum ash. Moreover, the materials in different areas do not affect each other, and also ensure that the materials will not be scattered all over the ground in the box 1.

[0045] Specifically, there is a gap between the partition 7 and the turntable 21. The aluminum ash on the turntable 21 can be leveled by the partition 7. When the aluminum ash is rotated and conveyed on the turntable 21, it passes under the partition 7, thereby leveling the aluminum ash by the partition 7. After the leveled aluminum ash is rotated to the suction area 212, the suction effect of aluminum ash can be guaranteed.

[0046] In some embodiments, a baffle 8 is provided inside the cavity, the baffle 8 is provided on the outer periphery of the turntable 21, the inner surface of the baffle 8 is provided with a sealing element 81 that abuts against the outer ring of the turntable 21, and a discharge port 84 is provided on the baffle 8 corresponding to the output end of the scraper 4.

[0047] In this application, the enclosure 8 is set around the outer ring of the turntable 21 and sealed by the sealing element 81 to ensure the sealing effect between the enclosure 8 and the turntable 21, preventing aluminum ash from flowing out from the edge of the turntable 21. This ensures that the aluminum ash is only inside the enclosure 8 and will not drift outside the enclosure 8, thus ensuring the cleanliness of the box 1.

[0048] Specifically, the crushing component 5 has a receiving port on its upper part, which is located directly below the discharge port 84. It can receive the aluminum dross scraped off by the scraper plate 4 and feed it into the crushing component 5.

[0049] In some embodiments, a suction hood 31 is provided at the suction port of the suction pipe 3. The suction hood 31 is filled in the suction area 212, and the outer side of the suction hood 31 abuts against the partition 7 and the enclosure 8.

[0050] In this application, the suction hood 31 abuts against the partition 7 and the enclosure 8, so that the suction hood 31, the partition 7 and the enclosure 8 form a relatively closed space, which facilitates the suction of aluminum ash in the suction area 212 under the action of negative pressure suction.

[0051] In some embodiments, the enclosure 8 plate is provided with an air inlet 82 that communicates with the material suction area 212, and the air inlet 82 is aligned with the upper surface of the turntable 21.

[0052] Specifically, the air inlet 82 is a strip-shaped hole, and the air inlet 82 is flush with the upper surface of the turntable 21. When the suction pipe 3 sucks in aluminum dust on the turntable 21, the outside air will enter the enclosure 8 through the air inlet 82, thereby converging the aluminum dust at the enclosure 8 towards the center, which facilitates the suction of aluminum dust in the entire suction area 212, and avoids the situation where some aluminum dust cannot be sucked in by the suction pipe 3 at the edge of the turntable 21, thus ensuring that the suction pipe 3 can fully suck in aluminum dust in the suction area 212.

[0053] In some embodiments, a filter screen 32 is provided inside the suction hood 31.

[0054] In this application, aluminum ash can be filtered through the filter screen 32 at the suction hood 31 to prevent particulate aluminum dross from being sucked into the suction pipe 3, thereby further ensuring the quality of subsequent aluminum ash processing. Specifically, the mesh size of the filter screen 32 should not be too fine to ensure the suction force of the suction pipe 3 on the aluminum ash.

[0055] In some embodiments, the housing 1 is provided with an adjustment component 9 for controlling the lifting and lowering of the suction hood 31.

[0056] In this application, the suction hood 31 can be adjusted up and down via the adjustment component 9. When the suction hood 31 is adjusted upwards, the gap between the suction hood 31 and the turntable 21 increases, which improves the fineness of the aluminum ash sucked in. When the suction hood 31 is adjusted downwards, the gap between the suction hood 31 and the turntable 21 decreases, which reduces the fineness of the aluminum ash sucked in. Thus, the fineness of the aluminum ash can be adjusted according to the specific processing purpose of the aluminum ash. It not only has the function of aluminum ash conveying, but also the function of secondary screening of aluminum ash. When the suction hood 31 is adjusted upwards, the aluminum ash powder sucked in by the suction pipe 3 is finer, and the material (granular aluminum slag and aluminum ash with a relatively large diameter) retained on the turntable 21 will increase. At this time, the scraper 4 in this application scrapes the material retained on the turntable 21 to the crushing component 5 for secondary crushing, and then returns it to the turntable 21 through the return component 6 to ensure that aluminum ash of the required particle size can be obtained.

[0057] In some embodiments, the partition 7 and the enclosure 8 are provided with a sealing boss 83 on the side facing the suction area 212, and an elastic sealing ring 33 is provided on the outer side of the suction cover 31, the elastic sealing ring 33 abutting against the sealing boss 83.

[0058] In this application, the elastic sealing ring 33 has a certain elastic expansion and contraction range, and the lifting range of the suction hood 31 is within the elastic expansion and contraction range of the elastic sealing ring 33. That is, during the up and down adjustment of the suction hood 31, the elastic sealing ring 33 can always be in contact with the sealing boss 83, ensuring the sealing while ensuring the lifting and lowering adjustment of the suction hood 31.

[0059] In some embodiments, the adjustment assembly 9 includes an adjustment motor 91 and an adjustment screw 92. One end of the adjustment screw 92 is connected to the power end of the adjustment motor 91, and the other end of the adjustment screw 92 is connected to the suction hood 31 by a thread. The housing 1 is provided with a maintenance window 12 opposite to the suction hood 31.

[0060] In this application, by adjusting the motor 91 to drive the adjusting screw 92 to rotate, the suction hood 31 is moved up and down. When the suction hood 31 is moved to the maintenance window 12, the suction hood 31 can be disassembled and maintained, and the filter screen 32 on the suction hood 31 can be cleaned and replaced.

[0061] The aluminum ash conveying device introduces aluminum ash into the box 1 through the feed inlet 11. The aluminum ash is spread on the turntable 21. The turntable 21 is rotated by the power unit 22. The aluminum ash rotates to the bottom of the suction pipe 3. The suction pipe 3 adsorbs and conveys the aluminum ash powder spread on the turntable 21. Some larger particles will remain on the turntable 21 and continue to rotate with the turntable 21. The scraper 4 scrapes the particles retained on the turntable 21 to the crushing component 5 below for secondary crushing. The material after secondary crushing is returned to the material tray through the return component 6, so that no manual cleaning is required, saving labor and ensuring the processing progress of aluminum ash.
