DETAILED DESCRIPTION

[0021] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] The spacing between the stirring elements of the traditional anti-overflow stirring kettle is fixed and cannot be adjusted according to the amount of solvent inside the kettle body 1, so that the stirring element 2 is vacant and has low utilization rate. The anti-overflow stirring kettle generally includes a kettle body 1, which has a processing chamber 11, and a defoaming stirring group is arranged in the processing chamber 11. A feed pipe 12 with a valve is arranged at the top of the kettle body 1, and a discharge pipe 13 with a valve is arranged at the bottom of the kettle body 1. An overflow pipe 14 is also arranged near the top of the kettle body 1. The feed pipe 12, the discharge pipe 13 and the overflow pipe 14 are all connected to the processing chamber 11 of the kettle body 1. The feed pipe 12 is used to inject battery powder and leaching solvent into the processing chamber 13, the discharge pipe 13 is used to discharge the material, and the overflow pipe 14 is used to discharge the high-level bubbles. A heating mechanism is arranged inside the kettle body 1 to heat the battery powder and the leaching solvent to dissolve them and separate the target metal. Since bubbles are generated during the leaching of battery powder, a defoaming stirring group is installed in the kettle body 1, and the bubbles inside the processing chamber 11 are stirred and eliminated by the defoaming stirring group.

[0023] In order to improve the utilization rate of the stirring member 2 and reduce waste, a battery powder leaching anti-overflow stirring kettle is designed, such as Figure 1As shown, the defoaming and stirring group includes a transmission unit 3, an adjustment unit 4 and a plurality of vertically arranged stirring members 2. The transmission unit 3 is used to drive the plurality of stirring members 2 to rotate, and the adjustment unit 4 is used to drive the plurality of stirring members 2 to vertically displace, so that the plurality of stirring members 2 are concentrated in the bubble area and the liquid area below the bubble area, thereby being able to effectively eliminate and stir the bubbles, and also facilitating more uniform stirring to ensure complete leaching.

[0024] In order to better adjust the positions of the multiple stirring elements 2, an infrared rangefinder 6 for detecting the liquid level in the kettle is provided on the top of the kettle body 1. The position of the stirring element 2 is adjusted by the electric push rod 41 based on the liquid level detected by the infrared rangefinder 6.

[0025] like Figure 2 and 3 As shown, specifically, the transmission unit 3 includes a servo motor 31 disposed on the top of the kettle body 1 and a transmission shaft 32 fixedly connected to the output end of the servo motor 31. The transmission shaft 32 is placed in the processing chamber 11, and a plurality of stirring members 2 are evenly spaced and arranged on the transmission shaft 32. The servo motor 31 drives the transmission shaft 32 to rotate, and thus drives the plurality of stirring members 2 to rotate synchronously.

[0026] The plurality of stirring members 2 are divided into a bottom stirring member 24 and a plurality of upper stirring members 23. The bottom stirring member 24 is fixedly connected to the transmission shaft 32. The plurality of upper stirring members 23 are slidably arranged on the transmission shaft 32 through elastic members 5. The elastic members 5 are arranged between adjacent stirring members 2. The plurality of stirring members 2 are limited by the fixed bottom stirring member 24 and the adjusting unit 4.

[0027] The transmission shaft 32 is a prism, and the stirring member 2 includes a mounting sleeve 21 and a plurality of stirring blades 22. The plurality of stirring blades 22 are circumferentially arranged on the periphery of the mounting sleeve 21. The mounting sleeves 21 of the plurality of upper stirring members 23 are slidably mounted on the prism, and the mounting sleeves 21 of the bottom stirring member 24 are fixedly connected to the prism. The two ends of the elastic member 5 are respectively against the mounting sleeves 21 of the adjacent stirring member 2. When the mounting sleeve 21 rotates, it will drive the plurality of stirring blades 22 to revolve, so that the stirring blades 22 can break and eliminate bubbles. The transmission shaft 32 is a prism to prevent the mounting sleeve 21 from rotating relative to it, so that the mounting sleeve 21 can only slide longitudinally along the transmission shaft 32 under the action of the elastic member 5.

[0028] The adjustment unit 4 includes an electric push rod 41, which has a cylinder end and a push rod end. The cylinder end is fixedly arranged on the transmission shaft 32, and the push rod end is provided with a push block 42 slidably assembled on the transmission shaft 32. The push block 42 abuts against the upper stirring member 23 placed at the top. By starting the electric push rod 41, the push block 42 can be driven to move. The push block 42 is the height limit of the upper stirring member 23 at the top, so that the height of multiple stirring members 2 can be adjusted in coordination with the elastic member 5. Among them, there are 4 to 6 stirring members 2, and the elastic member 5 can be a tension rope, a return spring or a tension spring, preferably a return spring.

[0029] The upper stirring piece 23 at the top is adjusted by the adjustment unit 4, and two adjacent stirring pieces 2 are connected by an automatically deformable spring. When the positions of the upper stirring piece 23 at the top and the bottom stirring piece 24 at the bottom are determined, the heights of the remaining stirring pieces 2 will be automatically adjusted under the elastic action of the spring, so that the heights of the multiple stirring pieces 2 can be automatically adjusted, so that the multiple stirring pieces 2 are evenly distributed in the upper bubble area and the lower liquid area, thereby ensuring the defoaming effect.

[0030] The above description is only illustrative rather than restrictive of the present invention. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the appended claims, but all will fall within the scope of protection of the present invention.
