Description

Technical Field

[0001] This utility model relates to the field of improving the uniformity of zinc paste for alkaline manganese batteries, and specifically to a stirring device for improving the uniformity of zinc paste for alkaline manganese batteries. Background Technology

[0002] For alkaline manganese batteries, the uniformity of the zinc paste area not only affects the battery's discharge performance, but also the uniformity of zinc paste injection and battery weight during the production process. In traditional stirring methods, the viscosity of the zinc paste gradually changes over time, resulting in unevenness between the top and bottom of the zinc paste, which in turn affects the battery's discharge performance. Therefore, this utility model proposes a stirring device to improve the uniformity of zinc paste in alkaline manganese batteries to solve the above problems. Utility Model Content

[0003] In order to overcome the defects in the prior art, this utility model provides a stirring device to improve the uniformity of zinc paste for alkaline manganese batteries. By increasing the vacuum conditions, the gas generated by the self-dissolution of zinc powder and the gas introduced during the stirring process are eliminated. At the same time, by centrifugal stirring, gravity mixing is used to avoid damaging the structure of the binder and zinc powder.

[0004] Technical solution

[0005] A stirring device for improving the uniformity of zinc paste in alkaline manganese batteries includes a zinc paste container, in which zinc paste is placed. A top cover is rotatably mounted on the upper side of the zinc paste container, and a clamp capable of rotating and driving the zinc paste container is mounted on the lower side of the zinc paste container. A vacuum pump is connected to the top cover.

[0006] Furthermore, the top cover and the zinc paste container are connected by a rotatable and sealing structure.

[0007] Furthermore, the upper cover is connected to the vacuum pump via an air guide pipe.

[0008] Furthermore, the top cover is also equipped with a pressure gauge for detecting the internal air pressure of the zinc paste container.

[0009] Furthermore, the clamp is rotated by an external power structure.

[0010] Beneficial effects

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] By increasing the vacuum conditions, the gases generated by the self-dissolution of zinc powder and the gases introduced during the stirring process are eliminated. At the same time, by centrifugal stirring, the mixture is mixed by gravity without damaging the binder and the structure of the zinc powder. Attached Figure Description

[0016] To better illustrate the content of this utility model, the following description is provided in conjunction with the accompanying drawings and embodiments:

[0017] have Figure 1 As shown, this utility model discloses a stirring device for improving the uniformity of zinc paste in alkaline manganese batteries, including a zinc paste tank 2, zinc paste 1 placed inside the zinc paste tank 2, an upper cover 4 rotatably mounted on the upper side of the zinc paste tank 2, a clamp 3 that can rotate and drive the zinc paste tank 2 to rotate on the lower side of the zinc paste tank 2, and a vacuum pump 7 connected to the upper cover 4.

[0018] Furthermore, the top cover 4 and the zinc paste container 2 are connected by a rotatable and sealing structure.

[0019] Furthermore, the upper cover 4 and the vacuum pump 7 are connected by an air guide pipe 6.

[0020] Furthermore, the upper cover 4 is also equipped with a pressure gauge 5 for detecting the internal air pressure of the zinc paste container 2.

[0021] Furthermore, the clamp 3 is rotated by an external power structure.

[0022] Specifically, during the mixing process, the vacuum pump 7 is used to evacuate the air from the inside of the zinc paste container 2 to increase the vacuum level inside the zinc paste container 2. Then, the external power structure drives the clamp 3 to rotate, which in turn drives the zinc paste container 2 to rotate. At this time, the top cover 4 remains stationary (it can be fixed by the clamping mechanism).

[0023] When the zinc paste container 2 rotates, the zinc paste 1 inside is subjected to vacuum centrifugal stirring;

[0024] By increasing the vacuum conditions, the gases generated by the self-dissolution of zinc powder and the gases introduced during the stirring process are eliminated. At the same time, by centrifugal stirring, the mixture is mixed by gravity without damaging the binder and the structure of the zinc powder.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the technical solutions of this utility model have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
