Description

Technical Field

[0001] The utility model belongs to the technical field of battery production, in particular to a low-temperature acid adding device for batteries. Background Art

[0002] At present, the acid addition method of lead-acid batteries mainly adopts the rich liquid quantitative method to confirm the electrolyte volume. First, the quantitative barrel is completely filled, and then the excess acid is extracted according to the quantitative height through the quantitative tube. This method is quantitative according to volume, the quantitative effect is poor, the electrolyte loss is serious, and the employee adjustment method is cumbersome; at the same time, since each time the quantitative method is rich liquid, the electrolyte temperature rises seriously, which has a certain impact on the low temperature performance of the battery; and in the process of charging and acid addition, the temperature control of the lead-acid battery directly affects the low temperature performance of the battery. At present, we use cold storage to cool the electrolyte to 10-15℃, but the overall difficulty of lowering the temperature of the electrolyte increases, and in the process of transferring the electrolyte, there will be problems such as temperature rise, which affects the temperature control effect of the electrolyte. Therefore, it is urgent to study a low-temperature acid addition device for batteries to solve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0005] The utility model discloses a low-temperature acid-adding device for batteries, comprising a workbench for placing batteries, a low-temperature box and a metering pump; a plurality of metering cups are vertically placed side by side in the low-temperature box; the upper ports of the plurality of metering cups are connected to a first delivery pipe; the plurality of the first delivery pipes are inserted on the top wall of the low-temperature box; the ends of the plurality of the first delivery pipes away from the metering cups are connected by a transfer pipe; the transfer pipe is connected to a second delivery pipe; the end of the second delivery pipe away from the transfer pipe is connected to the outlet end of the metering pump; the inlet end of the metering pump is connected to an acid liquid input pipe; the lower ends of the plurality of metering cups are connected to a third delivery pipe; the plurality of the third delivery pipes are inserted on the bottom wall of the low-temperature box; the ends of the plurality of the third delivery pipes away from the metering cups are vertically connected to transition cups; the lower ends of the plurality of transition cups are connected to acid liquid output pipes corresponding to the workbench.

[0006] As a preferred technical solution of the utility model, a pair of support columns are vertically fixed side by side on the upper surface of the workbench; a first mounting plate and a second mounting plate distributed vertically are horizontally fixed side by side between the two support columns; the low temperature box is placed on the upper surface of the first mounting plate; a plurality of transition cups are interspersed on the second mounting plate; the upper ends of the two support columns are connected by a third mounting plate; the metering pump is horizontally fixed on the upper surface of the third mounting plate; a carrying plate is horizontally fixed in the low temperature box; and a plurality of metering cups are interspersed on the carrying plate.

[0007] As a preferred technical solution of the utility model, a control valve is installed on the second delivery pipe.

[0008] The utility model has the following beneficial effects:

[0009] The utility model inserts one end of the acid liquid output pipe away from the transition cup into the acid filling port of the storage battery on the workbench, and automatically and quantitatively adds the acid liquid into the quantitative cup of the low temperature box according to the acid amount conversion of the corresponding model through the automatic quantitative acid adding structure formed by the acid liquid input pipe, the quantitative pump, the second delivery pipe, the transfer pipe and the first delivery pipe, thereby eliminating the need for manual adjustment and ensuring the quantitative accuracy. The low temperature box is used to control the temperature of the acid liquid in the quantitative cup, and the acid liquid in the quantitative cup is subjected to three cooling and cold acid treatments to ensure that the temperature of the acid liquid is controllable, and then the acid liquid is added into the quantitative cup through the third delivery pipe, the transition cup and the like. The cup and the acid output pipe inject the cooled acid into the battery, thereby realizing the low-temperature acid adding operation of the battery, which not only effectively ensures the accuracy of the quantitative delivery of the electrolyte, laying the foundation for the subsequent acid extraction-free process, but also can control the electrolyte from the original 10-15℃ to 5-10℃, effectively improving the low-temperature performance of the lead-acid battery, but also can improve the consistency of the acid adding of the lead-acid battery, reduce the difficulty of the operation process, reduce the electrolyte loss in the production process, and can also improve the problem that the electrolyte cannot be reduced to the required temperature during the battery acid adding process.
