[0003] Aluminum ash vibration is the first step in aluminum fly ash treatment. Its main purpose is to loosen and drop the aluminum fly ash attached to the inner wall of the equipment or container by vibration. After the aluminum ash is vibrated, gas (such as air or inert gas) is injected into the aluminum fly ash through the aluminum ash blowing equipment to disperse and suspend the particles in the aluminum fly ash, so as to further separate the different components in the aluminum fly ash and prepare for subsequent treatment and reuse.

[0004] However, in the prior art, when aluminum ash is sprayed, gas needs to be injected to suspend it and stir it, so that the implementation process requires the use of a mechanical stirring structure in conjunction with the gas circuit, and a corresponding adaptive control system needs to be added to coordinate the spraying and stirring, which makes the implementation cost high and the control difficulty greater, which is not conducive to practical application.

[0034] Example 2

[0035] like Figure 2 and Figure 3As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the mixing mechanism includes a rotating shaft 7, the rotating shaft 7 is set as a hollow structure, and a plurality of hollow stirring rods 8 are fixedly connected to the outer side of the rotating shaft 7, the interior of the hollow stirring rods 8 is communicated with the interior of the rotating shaft 7, the top of the aluminum ash bin 4 is fixedly connected to a cover body 29, the rotating shaft 7 is rotatably connected to the bottom of the cover body 29, the top of the rotating shaft 7 extends to the top of the cover body 29 and is fixedly connected to a rotary joint 12, a motor 10 is fixedly installed on the outer side of the aluminum ash bin 4, a driving pulley 14 is fixedly connected to the output end of the motor 10, a driven pulley 11 is fixedly connected to the outer side of the rotating shaft 7, the driving pulley 14 and the driven pulley 11 are connected by belt transmission, and an air intake pipe 13 is fixedly connected to the side of the rotary joint 12 away from the rotating shaft 7.

[0037] Example 3

[0038] like Figure 3 and Figure 4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the blowing mechanism includes a transmission bin 24 fixedly connected to the central position of the bottom of the cover body 29, a piston cylinder 25 is fixedly connected to the central position of the bottom of the transmission bin 24, the rotating shaft 7 is rotatably connected to the transmission bin 24 and the piston cylinder 25, a piston plate 26 is slidably connected between the inner walls of the piston cylinder 25, the interior of the rotating shaft 7 is provided with two hollow parts, an air inlet 71 and an air outlet 72, an air inlet 18 communicating with the air inlet 71 is opened on the outer side of the rotating shaft 7, and an air outlet 19 communicating with the air outlet 72 is also opened on the outer side of the rotating shaft 7, the air inlet 18 and the air outlet 19 are both located inside the piston cylinder 25 and on both sides of the piston plate 26, a connecting hole 27 is opened on the piston plate 26, the interior of the air inlet 18 and the connecting hole 27 are both arranged as one-way valves, and a plurality of blowing ports 9 communicating with the interior thereof are opened on the hollow stirring rod 8.

[0039] In this embodiment, when the piston plate 26 moves downward, the one-way valve in the air inlet 18 is connected, while the one-way valve in the connecting hole 27 is blocked. As the piston plate 26 moves downward, negative pressure is generated in the piston cylinder 25, allowing external gas to enter the piston cylinder 25. The inert gas can be injected by connecting the air inlet pipe 13 to an external inert gas source. When the piston plate 26 moves upward, the one-way valve in the air inlet 18 is blocked, while the one-way valve in the connecting hole 27 is connected. As the piston plate 26 moves upward, the gas in the piston cylinder 25 moves from the top of the piston plate 26 to the bottom, and is sprayed into the aluminum ash bin 4 through the air outlet 72, the hollow stirring rod 8 and the blowing port 9.

[0040] like Figure 3 and Figure 5 As shown, preferably, the blowing mechanism also includes a linkage rod 28, which is slidably connected to the bottom of the inner wall of the transmission bin 24, and the bottom of the linkage rod 28 extends to the inside of the piston cylinder 25 and is fixedly connected to the piston plate 26. The top of the linkage rod 28 is fixedly connected to an annular transmission block 15, and the inner side of the annular transmission block 15 is fixedly connected to a transmission buckle 17. A spiral groove 16 is provided on the outer side of the rotating shaft 7 located inside the transmission bin 24, and the transmission buckle 17 is slidably connected to the transmission groove.

[0041] In this embodiment, the spiral groove 16 rotates relative to the annular transmission block 15 by rotating the rotating shaft 7, and the annular transmission block 15 is limited by the linkage rod 28 and can only reciprocate, so that the piston plate 26 performs piston motion in the piston cylinder 25.

[0042] like Figure 1 and Figure 3 As shown, preferably, a filling pipe 21 is arranged on the cover body 29, and a top cover 22 is movably connected to the pipe mouth of the filling pipe 21, and one end surface of the top cover 22 is arranged as a screen structure.

[0043] In this embodiment, the top cover 22 can prevent the aluminum ash bin 4 from overflowing outwards. When aluminum ash needs to be injected, the top cover 22 can be removed and the filling pipe 21 can be connected to the aluminum ash output pipe.

[0044] like Figure 1 and Figure 2 As shown, preferably, a silo wall vibrator 20 is fixedly installed on the outer side of the aluminum ash silo 4.

[0045] In this embodiment, the silo wall vibrator 20 is operated to loosen and drop the aluminum fly ash attached to the inner wall of the equipment or container.

[0046] like Figure 3 As shown, preferably, a partial area of ​​the aluminum ash bin 4 near the bottom is set as an inverted cone structure, and a scraper 23 is fixedly connected to the outer side of the rotating shaft 7, and the scraper 23 contacts the inner wall of the cone structure of the aluminum ash bin 4.

[0047] In this embodiment, the aluminum ash bin 4 can be easily cleaned by the scraper 23 to avoid adhesion to the bottom of the bin wall.

[0048] The working principle of the integrated fly ash treatment device is described in detail below.

[0049] like Figure 1-5As shown, when the aluminum ash is vibrated, the silo wall vibrator 20 works to loosen and drop the aluminum fly ash attached to the inner wall of the equipment or container, and the motor 10 is controlled to work to drive the active pulley 11 to rotate, and the driven pulley 14 is driven to rotate through the belt transmission, so that the rotating shaft 7 rotates, and then the hollow stirring rod 8 is turned over to stir the aluminum ash. At the same time, due to the rotation of the rotating shaft 7, the spiral groove 16 rotates relative to the annular transmission block 15, and the annular transmission block 15 is limited by the linkage rod 28 and can only do reciprocating motion, so that the piston plate 26 does piston motion in the piston cylinder 25. When the piston plate 26 moves downward, the one-way valve in the air inlet 18 is connected, and the one-way valve in the connecting hole 27 is blocked. Furthermore, as the piston plate 26 moves downward, negative pressure is generated in the piston cylinder 25, causing external gas to enter the piston cylinder 25. The inert gas can be injected by connecting the air inlet pipe 13 to an external inert gas source. When the piston plate 26 moves upward, the one-way valve in the air inlet 18 is blocked, while the one-way valve in the connecting hole 27 is connected. As the piston plate 26 moves upward, the gas in the piston cylinder 25 moves from the top to the bottom of the piston plate 26, and is sprayed into the aluminum ash bin 4 through the air outlet 72, the hollow stirring rod 8 and the blowing port 9, thereby realizing the aluminum ash spraying operation. The process only requires a single drive and does not require the support of the air circuit. At the same time, the blowing and stirring processes are synchronized, and do not require too many control systems, which greatly facilitates practical applications.

[0050] After the spraying is completed, the discharger 5 is used to quantitatively feed the reamer scale 3. The reamer scale stirs the aluminum fly ash evenly through the rotating blade and measures the required amount at the same time. This step can ensure the uniformity and consistency of the aluminum fly ash and provide accurate material parameters for subsequent processing or utilization. After the previous pretreatment steps, the aluminum fly ash is sent to the subsequent processing process through the delivery pump.

[0051] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
