[0023] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0024] Reference Figure 1~Figure 4 : A stirring device for aluminum oxidation includes a rack, which includes a middle column 1, a left column 2 and a right column 3. The left column 2 and the right column 3 are connected to the two ends of the middle column 1. The left column 2 and the right column 3 both include a motor 5. The motor 5 is installed at one end of the left column 2 and the right column 3 close to the middle column 1. The shaft of the motor 5 is connected to a stirring shaft 7 installed inside the left column 2 and the right column 3. The other end of the stirring shaft 7 is connected to a stirring disk 6. The stirring disk 6 is installed outside the left column 2 and the right column 3.

[0025] In this embodiment, the middle column 1, the left column 2 and the right column 3 are all square tubes made of metal, and the left column 2 and the right column 3 are welded to both ends of the middle column 1. The position where the middle column 1 is located is defined as the top.

[0026] A cylinder 8 is provided inside the left column 2 and the right column 3. The cylinder 8 is hollow in the middle and has baffles 9 at both ends. The shape of the baffle 9 matches the shape of the ends of the left column 2 and the right column 3, so that the baffle 9 can be welded to the ends of the left column 2 and the right column 3. A through hole is provided in the baffle 9 corresponding to the middle part of the cylinder 8.

[0027] A motor 5 is provided at the upper baffle 9, with the shaft of the motor 5 facing the inside of the cylinder 8. The shaft of the motor 5 is connected to the stirring shaft 7, which is located inside the cylinder 8 and does not contact the cylinder 8. The other end of the stirring shaft 7 extends from the lower baffle 9 and is connected to a stirring disk 6.

[0028] In this embodiment, two stirring layers are provided on the stirring disk 6, which are divided into a first stirring layer and a second stirring layer, wherein the first stirring layer is located above the second stirring layer, and the first stirring layer and the second stirring layer are both provided with three stirring blades, defined as a first stirring blade 61 and a second stirring blade 62.

[0029] In this embodiment, the second stirring blade 62 is evenly arranged horizontally on the stirring plate 6, and the first stirring blade 61 and the second stirring blade 62 are arranged at an angle. Specifically, the first stirring blade 61 is arranged upward, and the angle between the first stirring blade 61 and the second stirring blade 62 in the horizontal plane is 30°, and the first stirring blade 61 and the second stirring blade 62 are staggered. A stirring belt 63 is provided at the bottom of the stirring plate 6, and the stirring belt 63 can be made of soft rubber, so that the stirring belt 63 can rotate irregularly when the stirring plate 6 rotates.

[0030] The setting of the first stirring layer and the second stirring layer can promote the transfer of substances in the lower part of the solution tank, so that they will not stay in one area, which is beneficial to the oxidation of aluminum. In addition, the first stirring blade 61 is set upward to increase the stirring area, but because it is set up by the rack, the first stirring blade 61 needs to avoid the lower part of the left column 2 and the right column 3, so the first stirring blade 61 is designed to have an angle of 30° with the second stirring blade 62 in the horizontal plane. The stirring belt 63 at the bottom of the stirring plate 6 can stir the area below the rack, and the soft rubber is used. The stirring belt 63 will rotate irregularly when the stirring plate 6 rotates, which will greatly increase the stirring range.

[0031] The stirring shaft 7, stirring disk 6, stirring blades and stirring belt 63 are all made of non-conductive materials, such as plastic; this avoids the influence of aluminum oxidation on the motor 5 and ensures safety.

[0032] In this embodiment, a clamp 4 is provided on the left column 2 and the right column 3, and the clamp 4 includes a spring 41, a movable plate 43 and a connecting rod 42, wherein a small hole is provided on the side wall of the left column 2 and the right column 3, and the spring 41 extends into the small hole, and one end of the spring 41 is fixed to the outer wall of the cylinder 8 inside the left column 2 or the right column 3, and the fixing method can be brazing; the other end of the spring 41 is fixedly connected to one end of the connecting rod 42, and the other end of the connecting rod 42 is fixedly connected to the movable plate 43. Finally, the left column 2 or the right column 3, the connecting rod 42 and the movable plate 43 form a receiving cavity with an opening upward. The length of the movable plate 43 is greater than the width of the left column 2 and the right column 3, which is convenient for the staff to pull the movable plate 43, increase the width of the receiving cavity, and put in or take out the aluminum material.

[0033] The clamp 4 is installed on the front side or the rear side of the left column 2 or the right column 3, that is, the clamp 4 is arranged perpendicular to the middle column 1. When there is no external force, the gap between the movable plate 43 and the left column 2 or the right column 3 is smaller than the thickness of the aluminum material. Such an arrangement is conducive to placing the aluminum material in the accommodating cavity of the clamp 4, and then clamping the aluminum material by the elastic force of the spring 41 to prevent the aluminum material from falling during the lifting process.

[0034] In this embodiment, a plurality of clamps 4 are provided on the front and rear sides of the left column 2 and the right column 3, which can increase the amount of aluminum material placed at a time. The clamps 4 on both sides are staggered to facilitate the installation of the spring 41; the clamps 4 on the same side are installed on the left column 2 and the right column 3 at equal intervals, and the horizontal heights of the corresponding clamps 4 on the same side are consistent, which is convenient for placing aluminum materials.

[0035] The method of using this embodiment is as follows: first, make a cylinder and baffles at both ends of the cylinder, and install the motor, stirring shaft and stirring plate with stirring blades installed, then weld the spring and connecting rod on the outer wall of the cylinder in sequence, and then weld the rectangular plate to the baffle. The rectangular plate corresponding to the spring is provided with a small hole for the spring to pass through. After welding is completed, a left column and a right column are formed; the left column and the right column are welded to the two ends of the middle column, and the motor is electrically connected to the power supply, and the motor does not enter the solution tank; the staff places the aluminum material on the fixture; then connects the rack to the wire, uses a crane to lift the rack and puts it into the solution tank; starts the motor to rotate the stirring blades and the stirring belt, and then passes low-voltage direct current to the rack for electrolytic oxidation; after the electrolytic oxidation is completed, the power supply is disconnected and the rack is lifted.

[0036] The above are merely embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have combinations and modifications of the aforementioned various technical features. Without departing from the spirit and scope of the present invention, those skilled in the art may make improvements, modifications, equivalent substitutions, or apply the structure or method of the present invention to other fields to achieve the same effect, all of which fall within the scope of protection of the present invention.
