DETAILED DESCRIPTION

[0016] Specific embodiment 1: Please refer to Figure 1-3A stirring device for nickel-hydrogen battery production comprises a stirring tank 10; the upper end of the stirring tank 10 is clamped with an upper cover 11; the upper end of the upper cover 11 is fixedly provided with a feeding port 12; the upper end of the upper cover 11 is fixedly connected to a motor 13; the output end of the motor 13 passes through the upper cover 11 and is fixedly connected to a rotating shaft 16; a discharge pipe 14 is fixedly provided at the lower end of the stirring tank 10; the discharge pipe 14 is provided with a stop valve 15; the lower end of the rotating shaft 16 is fixedly connected to a stirring blade 17; and a connecting pipe 11 is fixedly provided at the lower end of the stirring tank 10. 9; the inner side of the connecting pipe 19 is connected to the inner side of the stirring tank 10; a connecting pipe 3 24 is embedded in the inner side of the connecting pipe 19; a spring 25 is embedded in the inner side of the connecting pipe 3 24; one end of the spring 25 is fixedly connected to the connecting pipe 3 24; the other end of the spring 25 is fixedly connected to a slider 26; the slider 26 is slidably connected to the connecting pipe 3 24, and the shape of the slider 26 corresponds to the pipe opening of the connecting pipe 3 24; the end of the connecting pipe 19 away from the stirring tank 10 is fixedly connected to the storage cylinder 18; the connecting pipe 19 and The inner side of the material storage cylinder 18 is connected; the inner side of the material storage cylinder 18 is slidably connected to the push plate 27; two pairs of electric cylinders 20 are arranged on the side of the push plate 27 away from the mixing tank 10; the output end of each electric cylinder 20 is fixedly connected to the end face of the push plate 27 away from the mixing tank 10; the other end of the electric cylinder 20 is fixedly connected to the fixed plate 21; the material storage cylinder 18 is located on the upper side of the connecting pipe 19 and is fixedly connected to the connecting pipe 22; the connecting pipe 22 is connected to the mixing tank 10 and the inner side of the material storage cylinder 18; by arranging the material storage cylinder 18, the push plate 27, so that part of the raw material mixture can first enter the cavity surrounded by the storage cylinder 18 and the push plate 27, and then be sprayed back to the inner side of the mixing tank 10 from the upper side, which is equivalent to turning the upper and lower layers of the raw materials over, preventing the raw material mixture from being unevenly mixed during the mixing process, thereby improving the mixing efficiency; by providing the connecting pipe three 24, the spring 25, and the slider 26, after the raw material mixture enters the space surrounded by the push plate 27 and the storage cylinder 18, it cannot break through the slider 26 when it wants to flow in the reverse direction, so it can only be discharged from the nozzle 23, thereby improving the mixing efficiency.

[0017] See also Figure 2-3 There is a feeding hole 29 on the inner side of the connection between the material storage cylinder 18 and the connecting pipe 1 19; an electromagnet 30 is fixedly arranged on the inner side of the feeding hole 29 of the material storage cylinder 18; there is a discharging hole 28 on the connection between the material storage cylinder 18 and the connecting pipe 2 22; the slider 26 is a stainless steel slider; by setting the electromagnet 30, the raw material mixture is prevented from flowing into the space enclosed by the material storage cylinder 18 and the push plate 27. If the pressure is small, the slider 26 cannot move to the right. By adsorbing the slider 26, the position of the pipe mouth of the connecting pipe 3 24 can be kept open, thereby improving the mixing efficiency.

[0018] See also Figure 2The stirring tank 10 is fixedly provided with a nozzle 23 corresponding to the connecting pipe 22 ; the diameter of the output end of the nozzle 23 is smaller than the inner diameter of the connecting pipe 22 ; the nozzle 23 is connected to the connecting pipe 22 .

[0019] During operation, raw materials are added from the feeding port 12, and then the motor 13 is started. The output end of the motor 13 drives the rotating shaft 16 to rotate, and the stop valve 15 drives the stirring blade 17 to stir the raw materials; the electromagnet 30 is started, and the electromagnet 30 adsorbs the slider 26. Then, with the action of centrifugal force, the raw materials inside the mixing tank 10 move into the cavity surrounded by the push plate 27 and the storage cylinder 18. Then the electromagnet 30 is closed, and the slider 26 is reset to keep stable and buckle with the connecting pipe 3 24, leaving part of the raw materials in the cavity surrounded by the push plate 27 and the storage cylinder 18. At this time, the electric cylinder 20 is started, and the output end of the electric cylinder 20 extends, driving the push plate 27 to move to the left. The raw materials that originally entered from the feed hole 29 are now The raw materials are squeezed to the left side. Since the connecting pipe 3 24 is blocked during the movement of the slider 26 to the left, the raw materials can only be discharged from the discharge hole 28. Only a small amount of raw materials remain in the space between the slider 26 and the feed hole 29. The squeezed raw materials enter the connecting pipe 2 22 from the discharge hole 28. Finally, when passing through the nozzle 23, the pipe diameter becomes smaller, the pressure increases, and the injection speed increases, and the raw materials are re-mixed with the raw materials inside the mixing tank 10. After repeating the above process, part of the raw materials can be sprayed out through the nozzle 23 while the stirring blade 17 is stirring to prevent uneven mixing. Then, the motor 13 is turned off to control the output end of the electric cylinder 20 to extend, and then the stop valve 15 is opened to discharge the raw materials from the discharge pipe 14.
