It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0019] The utility model embodiment provides a special tool for stirring in an aluminum ash calcining kiln, such as Figure 1-2 As shown, it includes a forklift front fork station frame 4, a rotating shaft fixing sleeve 3 is welded on the outer wall of one side of the forklift front fork station frame 4, two rotating shaft fixing sleeves 3 are provided, and the two rotating shaft fixing sleeves 3 are symmetrically welded on the outer wall of one end of the forklift front fork station frame 4, the two ends of the rotating shaft 2 are respectively arranged on the inner sides of the two rotating shaft fixing sleeves 3, the rotating shaft 2 is rotatably connected on the inner wall of one side of the two rotating shaft fixing sleeves 3, a supporting steel pipe 1 is welded at the central position of the outer wall of one side of the rotating shaft 2, a heat insulation cover 6 is welded on the end of the supporting steel pipe 1 away from the rotating shaft 2, a circular seamless steel pipe 7 is welded at the central position of the outer wall of the side of the heat insulation cover 6 away from the supporting steel pipe 1, and the inner wall of one side of the heat insulation cover 6 is close to the circular seamless steel pipe 7. A motor 8 is fixedly connected to one side of the tube 7 by bolts, and a heat-insulating rod 13 is fixedly connected to the motor 8 through an output end on one side thereof. A heat-resistant steel rod 9 is keyed to one end of the heat-insulating rod 13, and a rake head 10 and a counterweight 11 are welded to an outer wall of one side of the heat-resistant steel rod 9. The rake head 10 is located on a horizontal side of the counterweight 11. A bearing 12 is arranged on the inner wall of the circular seamless steel tube 7. There are two bearings 12 in total, and both bearings 12 are arranged on the inner wall of the circular seamless steel tube 7. The heat-resistant steel rod 9 passes through the bearing 12. A fixing sleeve 5 is welded to the inner wall of the forklift front fork station frame 4. The fixing sleeve 5 is provided with a through hole for the supporting steel tube 1 to pass through and match, and the supporting steel tube 1 passes through the fixing sleeve 5.

[0020] It should be noted that, since the existing aluminum ash calcining and stirring tools need to be used in conjunction with a forklift and need to be heat-resistant, it is necessary to consider the instability of the forklift caused by shaking during the forward and backward processes and to facilitate the forklift driver's control during the stirring process using the tool. The present embodiment has a simple and reasonable structure and can work at a high temperature of 1200°C for a long time. The forklift is combined with a special tool for stirring in the aluminum ash calcining kiln to move smoothly and be precisely controlled. The rotating shaft design allows the forklift to move without shaking during the forward or backward process, and the rotation of the rake head 10 inside the aluminum ash calcining kiln can realize the turning and stirring of the aluminum ash in the aluminum ash calcining kiln, thereby ensuring that the aluminum ash is fully heated and improving the efficiency of aluminum ash processing.

[0021] Specifically, in this embodiment, this scheme mainly includes a forklift front fork station frame 4. When in use, the forklift inserts the front fork into the forklift front fork station frame 4 during driving. After the forklift front fork is lifted, the forklift front fork station frame 4 is lifted synchronously. The circular seamless steel pipe 7 and the rake head 10 are inserted into the aluminum ash calcining kiln. As the forklift moves forward or backward, the rake head 10 moves synchronously inside the aluminum ash calcining kiln. When stirring, the external power supply of the motor 8 is turned on. The motor 8 drives the heat-insulating rod 13 and the heat-resistant steel rod 9 to rotate through the output end on one side. Under the support of the bearing 12, the heat-resistant steel rod 9 can be stably rotated. The rake head 10 on the heat-resistant steel rod 9 rotates in the aluminum ash calcining kiln to realize the turning and stirring of the aluminum ash in the aluminum ash calcining kiln, ensuring that the aluminum ash is fully heated and improving the efficiency of aluminum ash processing. Since the heat-insulating cover 6 and the heat-insulating rod 13 are provided, the heat transfer can be blocked, thereby preventing the motor 8 from being damaged by high temperature.

[0022] In a further preferred embodiment of the present invention, Figure 1-Figure 2 As shown, the forklift front fork station frame 4 includes two steel sleeves made of Q235 steel and arranged side by side, each steel sleeve is about 1200mm long, which is convenient for the forklift front fork to enter smoothly. The bottoms of the two steel sleeves are welded on an iron plate, and the center distance between the two steel sleeves is about 800mm.

[0023] In this embodiment, by inserting the steel sleeve into the forklift front fork, the forklift front fork can lift the forklift front fork station frame 4, thereby realizing the vertical lifting and horizontal movement of the forklift front fork station frame 4.

[0024] In a further preferred embodiment of the present invention, Figure 1-Figure 2 As shown, the round seamless steel pipe 7 is a seamless steel pipe with a wall thickness of 30 mm, and the round seamless steel pipe 7, the heat-resistant steel rod 9, the rake head 10 and the counterweight 11 are all made of ZG 40 Cr 25 Ni 20 Made of Si2 steel, it can work at high temperature of 1200℃ for a long time.

[0025] In this embodiment, the circular seamless steel pipe 7, the heat-resistant steel rod 9, the rake head 10 and the counterweight 11 can work at a high temperature of 1200°C for a long time through the seamless steel pipe, thereby preventing the circular seamless steel pipe 7, the heat-resistant steel rod 9, the rake head 10 and the counterweight 11 from deforming and losing their stirring ability.
