Abstract

The proposed method of unification of external parameters of accumulator batteries when forming and charging the batteries in line production process consists in filling the batteries with electrolyte, grouping the batteries, placing the batteries into baths with cooling liquid, and forming the batteries after holding in the baths. The cooling liquid is supplied concurrently in all the baths by gravity, trough the pipelines of the recirculated water system, from the common pressure reservoir. Onreaching the upper limit level in the bath, excess liquid is drained in the accumulating vessel, fed first in the heat exchanger, and then in the pressure reservoir. Gases and aerosols released in the battery forming process are removed off each bath with uniform velocity in a result of ventilation gas exchange.

Description

aerosols, which makes it possible to stabilize the partial pressure and composition of the atmosphere above the surface of the coolant.

According to the information available to the authors, the proposed essential features characterizing the essence of the invention are not known in this section of technology.

The proposed technical solution can be used at enterprises for the production of rechargeable batteries with pasted electrodes, in particular - lead-acid types.

The "industrial implementation" criterion is confirmed by the relevance of the method and its practical connection to real production technologies.

To prove the possibility of implementing the proposed method, we will consider one of the options for its implementation on a specific structural basis.

In fig. a diagram of the possible layout of the nodes of the rod forming and battery charging section is given.

The diagram shows the minimum number of nodes, the coordinated functioning of which is able to ensure processing in full accordance with the program, as well as thermodynamic support of the process. All secondary details, the electrical circuit of the battery connection with the energy converters, as well as the operational information collection and control system diagrams are omitted.

As already mentioned, the cooling system works on a reverse cycle, that is, it is filled with water once, and then it is disconnected from the sewage and water supply lines. The objects of thermal stabilization are accumulator batteries 1, placed in baths 2. The thermal agent is water 3, which fills the baths up to the level of the drain hole 4 (not less than 9 o the height of the battery). Excess thermal energy released on the electrode plates during forming is absorbed by the water washing the battery cases. To organize the removal of this energy, the water in the baths is constantly exchanged. Cooled water (To) comes from pressure tank 5 by adjustable gravity. To maintain uniformity of physical conditions, the level difference between tank 5 and all baths is the same. In addition, water is supplied to the bath in parallel.

Excess water is removed by overflowing through permanently open drain holes 4, located at the same height from the bottom. The intensity of cooling is regulated by the rate of water exchange, achieving constancy of the temperature of the electrolyte (Tr). Water drained from all baths is collected in a common tank 6 (accumulators), with subsequent pumping by a pump 7 into a heat exchanger 8. The thermal balance of the closed system is restored by cooling the spent water in the heat exchanger (cooling room), where its temperature decreases as a result of intensive evaporation, as well as due to direct heat exchange with air. The cooled water accumulates in the pressure tank 5, from where it is again evenly distributed among the baths 2. During the many-hour forming process, the water circulates in the system according to the described scheme. After the formation and charging of the accumulators are completed, the baths are completely drained, draining the water into the accumulator, and the products are replaced with a new batch of them. For the next start of the cooling system, the baths are filled again and circulation is restored.

Intake umbrellas 9 of the forced gas exchange system are mounted above each bath, which are connected by means of air ducts 10 to the filter-ventilation device 13. In order to stabilize external conditions, the buffer process volumes 11 above the baths are separated from the workshop atmosphere by retractable curtains 12.

The compression created by the ventilation unit is distributed equally, which makes it possible to equalize the rate of removal of substances and gases from the volumes 11 and thus prevent the possibility of temperature fluctuations in the baths. In addition to the purely technical effect, curtains create protection of the shop atmosphere from substances harmful to the health of service personnel. It is natural that monitoring in such a responsible area of battery production is carried out using the most modern information technologies.

All design features of this unit serve to achieve one goal - to ensure the identity of thermal regimes in all baths without exception.

The proposed technical solution makes it possible to increase the output of high-quality products with the same technical characteristics during the flow production of batteries, by unifying the external mode parameters of the process of their formation and charging.
