[0021] 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.
[0022] Please see Figure 1-5 This utility model provides a technical solution: a rotary kiln for easy cleaning of aluminum ash slag, including a furnace body 1. A diversion device 3 is fixedly connected to the upper middle part of the furnace body 1 through a connecting bracket 35. The diversion device 3 includes a funnel-shaped guide plate 33. Several guide grooves 34 are opened on the surface of the guide plate 33. The tip of the guide plate 33 faces upward and is fixedly connected to a storage tank 31. A screening device 6 is fixedly installed on the inner wall of the furnace body 1 and directly below the guide grooves 34. A crushing device 5 is rotatably installed inside the screening device 6. A grinding device is rotatably installed at the bottom of the furnace body 1. A transmission device is installed inside the bottom of the furnace body 1 to drive the crushing device 5 and the grinding device to rotate synchronously.
[0023] Specifically, the storage tank 31 can filter out large impurities in the aluminum ash slag, avoiding excessive impurities that could affect the texture of the aluminum ash slag. The diversion device 3 can divert the aluminum ash slag when a large amount of aluminum ash slag needs to be processed, reducing the amount of aluminum ash slag in each screening device 6 and preventing it from being concentrated in one screening device 6 for crushing, thus reducing crushing efficiency. The grinding device grinds the crushed aluminum ash slag in a concentrated manner, thereby thoroughly grinding it into powder.
[0024] By setting a diversion device 3 inside the furnace body 1, a storage tank 31 is fixedly installed at the top of the diversion device 3, and a crushing device 4 is rotatably installed inside the storage tank 31. Multiple diversion holes 32 are opened on the periphery of the storage tank 31. The crushing device 4 can initially crush the aluminum ash slag added into the storage tank 31. The crushed aluminum ash slag is discharged through the diversion holes 32. However, stones and other impurities are hard and difficult to crush, so they remain in the storage tank 31. This makes it convenient to perform initial crushing and impurity filtration of the aluminum ash slag.
[0025] By setting a guide plate 33 with multiple guide channels 34, the aluminum ash slag discharged through the storage tank 31 falls into the guide channels 34. Through the diversion operation of the aluminum ash slag, it enters different screening devices 6 for crushing. Through the diversion and crushing operation, the storage amount of aluminum ash slag in each screening tank 61 can be reduced, avoiding the addition of too much aluminum ash slag, which would affect the crushing efficiency. The thoroughly crushed aluminum ash slag falls into the bottom of the furnace body 1, where it is ground into powder by the centralized grinding of the grinding device.
[0026] The storage tank 31 has several flow holes 32 on its periphery, each flow hole 32 corresponding to one of the guide grooves 34. A crushing device 4 is rotatably installed inside the storage tank 31, and the crushing device 4 includes crushing blades 41.
[0027] Specifically, large pieces of aluminum ash slag are crushed and guided by the diversion holes 32 into different guide channels 34, and then into different screening devices 6. The crushing blades 41 are existing technology. The top end of the first shaft 72 extends into the storage tank 31 and is rotatably connected to it. The crushing blades 41 are fixedly connected to the periphery of the first shaft 72, so that the rotation of the first shaft 72 can drive the crushing blades 41 to rotate, thereby achieving the initial crushing of the aluminum ash slag.
[0028] The furnace body 1 is provided with a first shaft 72 and a plurality of second shafts 73. The first shaft 72 and the plurality of second shafts 73 extend into the furnace body 1 and are fixedly connected to the transmission device. The top end of the second shaft 73 extends into the screening device 6 and is rotatably connected to it. The top end of the first shaft 72 extends into the storage tank 31 and is rotatably connected to it. The crushing device 5 includes crushing blades 51 fixedly connected to the second shafts 73. The grinding device includes a plurality of grinding blades 74, which are fixedly connected to the first shaft 72 and the second shafts 73 respectively.
[0029] Specifically, the rotation of the second shaft 73 drives the crushing blade 51 to rotate, crushing the small pieces of aluminum ash slag that enter the screening tank 61 into finer particles that enter the bottom of the furnace body 1. Meanwhile, the rotation of the first shaft 72 and the second shaft 73 drives the grinding blade 74 to rotate, thoroughly grinding the small particles of aluminum ash slag into powder.
[0030] The transmission device includes a main gear 7 rotatably disposed in the bottom of the furnace body 1, a plurality of auxiliary gears 71 rotatably connected to the furnace body 1 meshing around the main gear 7, a first shaft 72 fixedly connected to the main gear 7, and a second shaft 73 fixedly connected to the auxiliary gears 71.
[0031] Specifically, the rotation of the main gear 7 drives the rotation of the secondary gear 71. The rotation of the main gear 7 and the secondary gear 71 can drive the first shaft 72 and the second shaft 73 to rotate respectively. The rotation of the first shaft 72 and the second shaft 73 can drive the crushing device 4, the breaking device 5 and the grinding device to rotate synchronously, thereby realizing the crushing, breaking and grinding of aluminum ash slag.
[0032] The screening device 6 includes a screening tank 61.
[0033] Specifically, the screening tank 61 screens the aluminum ash slag that has been crushed into granules, so that the small particles of aluminum ash slag enter the bottom of the furnace body 1, while the large particles of aluminum ash slag continue to be crushed.
[0034] A furnace cover 2 is provided at the top of the furnace body 1. A feed inlet 21 is provided on the upper surface of the furnace cover 2, penetrating through its lower surface. The feed inlet 21 is located directly below the storage tank 31.
[0035] Specifically, aluminum ash is added through inlet 21, and the added aluminum ash falls into storage tank 31.
