[0024] As Figures 1 to 6 shown, the present utility model provides:

[0025] An automatic plugging type feeding structure for preventing overflow of fire and a rotary furnace for aluminum ash recovery, comprising a fixed seat 1, a load-bearing plate 2, a lifting plate 3, a support plate 4, a transport plate 5, a feeding plate 6, a plugging plate 7, a stirring drum 8 and a recovery furnace 9. The load-bearing plate 2 is arranged on the top of the fixed seat 1, the lifting plate 3 is arranged above the load-bearing plate 2, the support plate 4 is arranged above the lifting plate 3, the transport plate 5 is arranged above the lifting plate 3, the feeding plate 6 is arranged at one end of the transport plate 5, the plugging plate 7 is arranged above the transport plate 5, the stirring drum 8 is arranged above the transport plate 5, the recovery furnace 9 is arranged at one end of the transport plate 5, and a protective cylinder 10 in contact with the plugging plate 7 is arranged at one end of the recovery furnace 9.

[0026] The load-bearing plate 2 is horizontally adjusted under the action of the fixed seat 1, which is convenient for the user to accurately transport aluminum ash. Then, in cooperation with the lifting plate 3 and the support plate 4, the overall height of the device can be adjusted. Then, the horizontal positions of the transport plate 5 and the feeding plate 6 are adjusted. After the adjustment is completed, the aluminum ash is transported through the transport plate 5. The aluminum ash enters the interior of the protective cylinder 10 under the action of the feeding plate 6. The protective cylinder 10 is connected to the recovery furnace 9, which is convenient for processing the aluminum ash. When the device is lifted or lowered, it can drive the plugging plate 7 to move. The plugging plate 7 is adapted to the protective cylinder 10 at one end of the recovery furnace 9, which can reduce the overflow of flame during rotation. Finally, the stirring drum 8 is used to stir the aluminum ash, so as to realize the uniform transportation of the aluminum ash and enable the aluminum ash to be uniformly mixed with the additive, improving the processing effect of the aluminum ash. The stirring drum 8 stirs the aluminum ash and the additive. The uniformly stirred aluminum ash is sent into the recovery furnace 9 under the action of the transport plate 5. When the processing of the aluminum ash is completed, since the horizontal positions of the transport plate 5 and the feeding plate 6 are adjustable, when the recovery furnace 9 rotates in reverse, the aluminum ash will be dumped.

[0027] As Figure 1 and Figure 4 shown, a rectangular groove 11 adapted to the load-bearing plate 2 is opened at the top of the fixed seat 1, and a lead screw 12 is threaded through the interior of the load-bearing plate 2. The input end of the lead screw 12 is provided with a working motor.

[0028] The working motor is started, and the working motor drives the lead screw 12 to rotate, which is convenient for driving the load-bearing plate 2 to slide inside the rectangular groove 11, and then convenient for adjusting the horizontal position of the transport plate 5.

[0029] As Figure 4 and Figure 6As shown, vertical rods 13 are provided at the four corners of the top of the load-bearing plate 2. One end of each vertical rod 13 is slidably installed with a hollow cylinder 14 connected to the lifting plate 3. The lifting plate 3 and the load-bearing plate 2 are connected by a first hydraulic cylinder.

[0030] Start the first hydraulic cylinder. The first hydraulic cylinder drives the lifting plate 3, the lifting plate 3 drives the hollow cylinder 14, and the hollow cylinder 14 is adapted to the vertical rod 13, which facilitates the user to adjust the height of the transport plate 5.

[0031] As Figure 4 and Figure 6 As shown, there are four hollow cylinders 14 in total. Slots adapted to the support plate 4 are provided at the tops of two of the hollow cylinders 14. The other two hollow cylinders 14 are fixedly connected to the support plate 4. The support plate 4 and the hollow cylinder 14 with slots are connected by a second hydraulic cylinder. Symmetric limiting chutes 15 are provided on the outer side of one end of the transport plate 5. A round rod connected to the support plate 4 is arranged inside the limiting chute 15. A conveyor belt 16 is arranged inside the transport plate 5. Protective plates 17 are symmetrically arranged on the top of the transport plate 5.

[0032] Start the second hydraulic cylinder. The second hydraulic cylinder drives the support plate 4 to slide inside the slots at the tops of the hollow cylinders 14. When the height of the support plate 4 changes, the support plate 4 drives the round rod to slide inside the limiting chute 15, thereby facilitating the adjustment of the rotation angle of the transport plate 5 and facilitating the conveying of aluminum powder.

[0033] As Figure 4 and Figure 5 As shown, vertical plates 18 are symmetrically arranged on the top of the transport plate 5. The vertical plates 18 and the mixing cylinder 8 are connected by bearing rods. A discharge pipe is fixedly connected to the bottom of the mixing cylinder 8.

[0034] The transport plate 5 drives the vertical plates 18, and the vertical plates 18 are connected to the mixing cylinder 8 under the action of the bearing rods, which can ensure that the mixing cylinder 8 is always in a vertical state. At the same time, in cooperation with the discharge pipe at the bottom of the mixing cylinder 8, it is convenient to convey the aluminum ash material.

[0035] As Figure 4 and Figure 5 As shown, a gantry plate 19 is arranged on the top of the mixing cylinder 8. Positioning working screws are threadedly connected to both sides of the gantry plate 19. A first motor is arranged on the top of the gantry plate 19. A stirring rod 20 is arranged at the output end of the first motor. One end of the stirring rod 20 is provided with a spiral rod adapted to the discharge pipe. Stirring plates 21 are annularly distributed on the outer wall of the stirring rod 20.

[0036] Place the gantry plate 19 on the top of the mixing drum 8. Then rotate the working screw to facilitate the disassembly and assembly of the gantry plate 19 by the user. Next, drive the stirring rod 20, the stirring plate 21, and the screw rod to rotate through the first motor. The cooperation between the stirring rod 20 and the stirring plate 21 can evenly mix the aluminum ash and the additive. At the same time, the screw rod is adapted to the discharge pipe, enabling the device to discharge materials evenly.
