Description

Positive lead paste additive dispersion device Technical Field

[0001] This utility model relates to the field of mixing, and more specifically, it relates to a dispersion device for positive electrode lead paste additives. Background Technology

[0002] Positive electrode lead paste additives are mainly used in the positive electrode materials of lead-acid batteries to improve battery performance, such as increasing energy density, extending service life, and enhancing charge and discharge efficiency. The production of positive electrode lead paste additives requires the precise dispersion and mixing of raw materials such as barium sulfate, silicon dioxide, graphite, bismuth oxide, and organic additives, which necessitates the use of a dispersion device.

[0003] Most existing dispersion devices only have one feed inlet and one dispersion chamber. The raw materials are poured into the mixing chamber one after another for dispersion. Due to the different states and qualities of various raw materials, the sequential pouring can easily lead to agglomeration and stratification, which greatly increases the difficulty of dispersion and requires a long time to disperse evenly, thus reducing production efficiency to some extent.

[0004] Based on the above, the purpose of this utility model is to provide a positive electrode lead paste additive dispersion device to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a positive electrode lead paste additive dispersion device. This invention uses a rotating premixing disc and a dispersion tank, and multiple channels to allow multiple raw materials to be poured into the premixing disc simultaneously. The rotating premixing disc causes the multiple raw materials to be stacked in a spiral shape. The raw materials are then sprinkled into the dispersion tank through a sprinkling hole. Since the dispersion tank rotates in the opposite direction to the premixing disc, the raw materials are distributed more evenly. Subsequently, the dispersion disc disperses the raw materials.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a positive electrode lead paste additive dispersion device, including a support frame, a premixing disc and a dispersion tank rotatably connected to the support frame, a plurality of dispensing holes provided on the premixing disc, a discharge pipe provided on the dispersion tank, a valve one provided on the discharge pipe, a drive mechanism one provided on the support frame for driving the premixing disc and the dispersion tank to rotate in opposite directions, a dispersion disc rotatably connected inside the dispersion tank, a drive mechanism two provided on the support frame for driving the dispersion disc to rotate, and a plurality of through slots provided on the support frame for communicating between the premixing disc and the outside.

[0007] By adopting the above technical solution, when it is necessary to disperse the positive electrode lead paste additives, the premixing disc and the dispersion tank are driven to rotate in opposite directions by the first drive mechanism, and the dispersion disc is driven to rotate by the second drive mechanism. Then, multiple raw materials are poured into the premixing disc through multiple channels at the same time. Since the premixing disc is rotating, the multiple raw materials poured in will be piled up in a spiral shape in the mixing disc. The raw materials then fall into the dispersion tank below through multiple sprinkling holes. The falling raw materials will also be piled up in a spiral shape in the dispersion tank. Since the dispersion tank rotates in the opposite direction to the premixing disc, the raw materials will be distributed more evenly. Subsequently, the dispersion disc will disperse the raw materials.

[0008] The present invention is further configured such that: a plurality of premixing tanks are provided on the support frame, the number and position of the through slots correspond to the premixing tanks, a valve is provided in the through slots, a feed inlet is provided on the premixing tanks and a stirrer is rotatably connected thereto, and a drive mechanism is provided on the premixing tanks to drive the stirrer to rotate.

[0009] The present invention is further configured such that: the second driving mechanism includes a motor fixedly connected to the premixing tank, a driving shaft fixedly connected to the output shaft of the motor, a dispersing disc fixedly connected to the driving shaft, and the driving shaft rotatably connected to the premixing disc.

[0010] The present invention is further configured such that: the driving mechanism three includes a driving gear one fixedly connected to the driving shaft, and the agitator one has a driven gear fixedly connected to the driving gear one.

[0011] The present invention is further configured such that: the driving mechanism includes a motor two fixedly connected to the support frame, a driving gear two fixedly connected to the output shaft of the motor two, and an external gear ring and an internal gear ring meshing with the driving gear two respectively fixedly connected to the premixing disc and the dispersing barrel.

[0012] The present invention is further configured such that: a stirrer 2 is fixedly connected to the portion of the drive shaft inside the premixing disc, and the lower end face of the stirrer 2 is in contact with the premixing disc.

[0013] In summary, this utility model has the following beneficial effects:

[0014] This invention features a rotating premixing disc and a dispersion tank, with multiple premixing tanks used to premix similar raw materials. Multiple premixed raw materials are then simultaneously poured into the premixing disc via multiple channels. The rotating disc causes the raw materials to overlap in a spiral pattern. Under the action of a stirrer, the materials are further premixed. The raw materials are then sprinkled into the dispersion tank through a feeding hole. Because the dispersion tank rotates in the opposite direction to the premixing disc, the raw materials are distributed more evenly. The dispersion disc then disperses the raw materials. This design, through similar premixing, overall premixing, and dispersion, combined with the staggered distribution mechanism of the premixing disc, significantly reduces the possibility of material stratification and agglomeration, resulting in higher dispersion efficiency.

[0022] The positive electrode lead paste additive dispersion device, as shown in Figures 1 and 2, includes a support frame 1. A premixing disc 2 and a dispersion tank 3 are rotatably connected to the support frame 1. The premixing disc 2 has several feeding holes 4. A discharge pipe is fixedly connected to the dispersion tank 3. A valve is installed on the discharge pipe. The support frame 1 is equipped with a drive mechanism 1 that drives the premixing disc 2 and the dispersion tank 3 to rotate in opposite directions. A dispersion disc 5 is rotatably connected inside the dispersion tank 3. The support frame 1 is equipped with a drive mechanism 2 that drives the dispersion disc 5 to rotate. The support frame 1 is equipped with several through slots 6 that allow the premixing disc 2 to communicate with the outside.

[0023] Furthermore, several premixing tanks 7 are fixedly connected to the support frame 1. The number and position of the through slots 6 correspond to the premixing tanks 7. A valve 2 is installed in the through slot 6. The valve 2 is a solenoid valve. The premixing tank 7 is provided with a feed port 8 and a stirrer 9 is rotatably connected to it. The premixing tank 7 is provided with a drive mechanism 3 that drives the stirrer 9 to rotate.

[0024] Furthermore, the second drive mechanism includes a motor 10 fixedly connected to the premixing tank 7, a drive shaft 11 fixedly connected to the output shaft of the motor 10, a dispersing disk 5 fixedly connected to the drive shaft 11, and a drive shaft 11 rotatably connected to the premixing disk 2.

[0025] Furthermore, the drive mechanism three includes a drive gear 12 fixedly connected to the drive shaft 11, and a driven gear 13 fixedly connected to the stirrer 9 and meshing with the drive gear 12.

[0026] Furthermore, the drive mechanism includes a second motor 14 fixedly connected to the support frame 1, a second drive gear 15 fixedly connected to the output shaft of the second motor 14, and an outer gear ring 16 and an inner gear ring 17 that mesh with the second drive gear 15 fixedly connected to the premixing disc 2 and the dispersing tank 3, respectively.

[0027] Furthermore, a stirrer 18 is fixedly connected to the portion of the drive shaft 11 inside the premixing disc 2, and the lower end face of the stirrer 18 is in contact with the premixing disc 2.

[0028] Working principle: When it is necessary to disperse the positive electrode lead paste additive, raw materials in similar states are combined and poured into multiple premixing tanks 7 (for example, powdered materials are combined, solid granules are combined, and liquid materials are combined). Then, the drive shaft 11 is driven to rotate by the motor 10. The drive shaft 11 will drive the dispersion disk 5, the drive gear 12 and the stirrer 18 to rotate. The drive gear 12 then drives the stirrer 9 through the driven gear 13 to premix the raw materials in similar states in the premixing tanks 7. After the premixing is completed, the raw materials in multiple premixing tanks 7 are simultaneously sent into the premixing disk 2 through the valve 2.

[0029] In this process, the motor 214 drives the drive gear 215 to rotate, and the drive gear 215 then drives the premixing disc 2 and the dispersing tank 3 to rotate in opposite directions through the internal gear ring 17 and the external gear ring 16 respectively. As the premixing tank 7 rotates, various raw materials will accumulate in a spiral shape in the mixing disc. Then, under the action of the agitator 218, all the raw materials are premixed. In this process, the raw materials will fall into the dispersing tank 3 below through multiple sprinkling holes 4. The falling raw materials will also fall into the dispersing tank 3 in a spiral shape. Since the dispersing tank 3 rotates in the opposite direction to the premixing disc 2, the raw materials will be distributed more evenly. Subsequently, the dispersing disc 5 will disperse the raw materials. After the dispersion is completed, the materials will be discharged through the discharge pipe.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
