Description

Technical Field

[0001] The present application relates to the technical field of lead-acid battery manufacturing, and in particular to a lead pot assembly with a heating function. Background Art

[0002] In the lead-acid battery manufacturing process, cast welding is a crucial process in the lead-acid battery manufacturing process. The existing lead-acid battery cast welding method generally includes the following process: immersing the busbar mold in the lead liquid in the lead furnace so that the cavity on the busbar mold is filled with lead liquid, then taking the busbar mold out of the lead furnace, and then turning the battery bottom box with multiple pole groups on the busbar mold upside down so that the pole ears of the multiple pole groups are inserted into the lead liquid in the cavity of the busbar mold for cast welding, and then cooling the busbar mold and taking the battery bottom box out of the busbar mold.

[0003] Through searching, Chinese patent announcement number CN219944609U discloses a lead pot assembly with a heating function. The heating ring ends in the lead pot body are evenly and widely arranged to ensure heating efficiency and uniformity. The annular heating ring ends are close to the lead pot body. The heating ring ends increase the contact area between the heating tube and the lead material, thereby increasing the heating source and improving the heating efficiency, which is convenient for efficient production and heating of materials in the lead pot.

[0004] With respect to the above-mentioned related technologies, the inventors have found the following defects: in the above-mentioned schemes and the prior art, since the internal lead liquid has a large range, it cannot be guaranteed that each position receives the same amount of heat, which will cause a temperature difference in the heated temperature of the discharged lead liquid, which is not conducive to shaping when casting the lead for the pole ear. Therefore, a lead pot assembly with a heating function is proposed, which can heat the lead liquid at the discharge position again and reduce the temperature difference of the discharged lead liquid.

Then, when the inner plate moves upward, the lead liquid is pushed into the discharge pipe. The spirally distributed discharge pipe is in multi-layer annular contact with the heater, which increases the path and time for the heater to heat the lead liquid in the discharge pipe. When the lead liquid is discharged from the lower end of the liquid gathering ring, the temperature difference changes less.

When the arcuate tooth plate is alternately meshed with a plurality of meshing gears, lead liquid can be intermittently filled into different discharge pipes. When new lead liquid has not entered the discharge pipe, the flow rate of the lead liquid in the discharge pipe is reduced, increasing the time the lead liquid stays in the discharge pipe.

Then, when the inner plate 7 moves upward, the one-way cover plate 8 blocks the liquid hole 10, so that the inner plate 7 moves upward and the upper lead liquid can be pushed into the discharge pipe 4.

[0025] See also Figure 2 The connecting rod 6 is located at one end outside the drum 1 and is fixedly connected with a meshing ring 11. A reciprocating screw 12 is threaded through the upper surface of the meshing ring 11. The axis of the reciprocating screw 12 is arranged parallel to the axis of the drum 1.

When the inner plate 7 moves downward, the molten lead lifts the one-way cover plate 8 through the liquid hole 10, so that the molten lead can flow to the top of the inner plate 7. Then, when the inner plate 7 moves upward, the one-way cover plate 8 blocks the liquid hole 10, so that the inner plate 7 moves upward and can push the upper molten lead into the discharge pipe 4. Then, the heater 2 heats the molten lead in the discharge pipe 4 again, heats the molten lead to the maximum temperature, and reduces the temperature difference when the molten lead is discharged from the bottom of the liquid gathering ring 5.
