Description

The invention relates to the electrical industry and can be used for filling and shaping batteries and draining spent electrolyte.

The purpose of the invention is the expansion of the functionality of the device for filling the electrolyte, eliminating the overspending of the electrolyte by separating the flows of clean and spent electrolyte, reducing harmful emissions in the atmosphere. The composition of the proposed device for filling batteries (FIG. 1) includes sealing 1 and drain 2 containers, bubbler. 3, vacuum pump 4, rotary unit 5, control device b, two electrolyte flow indicators 7 and 3, tee 9 and 10, crosspiece 11, filling fittings 20-1 ... YO-P, consisting of liquid 22 and 23 air channels, as well as a system of controlled valves 12 .., 19, pipelines 21 and a charge-charging device 24.

The bubbler (FIG. 2) is made in the form of a sealed vessel 25 with a removable lid 25, which has an inlet 27, outlet 28, and 29 fittings, as well as two float valves 30 and 31. Inlet iguzer - 7, s; G of the lower part of the 5ap Dan, is made in the form of a long, blind side with a difficult side, a tube with a large number of small radial holes is intended to connect the bubbler to the filling path of the device.

The outlet fitting 28 mounted on the cover 26 is for connecting the bubbler to the vacuum pump.

A drain fitting 29, mounted on the bottom of the bubbler, makes it possible to drain the electrolyte accumulating in the bubbler ..

The float valves 30, 31 are mounted on special guides 32, 33 coaxially with the outlet 28 and the main 29 fittings, the bubbler requires preliminary preparation for work, for which, when the valve 18 is open, it is filled with electrolyte (through a special filling hole in the cover 26 or when removing of that cover 26} to a level a few centimeters above the inlet fitting 27. After that, oil is added to the bubbler to the level at which the lower float valve 31, which pops up, opens the drain fitting 29. After that, the valve 18 closes, the bubbler 3 p prepared for work.

During the pouring process, an electrolyte accumulates in the bezbober 3 and must be periodically drained. Due to the presence of a lower float valve 31, the possibility of oil getting into the filling path (through the inlet fitting 27) and draining it from the bubbler 3 (through the drain fitting 29) is excluded.

With a small amount of electrolyte accumulated in the bubbler 3, the upper float valve 30 hangs on the guide 32, while the outlet valve 28 is open, and the bubbler 3 is constantly connected to the vacuum pump 4. When a significant amount of electrolyte accumulates, the output float valve 30, blocks the outlet fitting 28, thus disconnecting the bubbler 3 from the vacuum

5 of pump 4 and eliminating the possibility of oil entering the vacuum system.

After preparation for operation of the bubbler 3, accumulators A1 ... Ap are installed and fixed on the rotary assembly 5 and the system of filling nozzles 20-1,., 20-p is mounted. It should be noted that the liquid channels 22 of the filling fittings 20 are made shorter than the air channels 23, and their lower sections along

Level 5 coincide with the lower sections of the filling holes of the batteries. The lower sections of the air channels 23 are made at a level corresponding to the required level of filling of the batteries 0 with electrolyte.

The proposed device operates as follows.

In the initial state, all controlled valves 12 ... 19 are closed.

5 . When the electrolyte is closed, the vacuum pump 4 is started by the command from the control device 6 and the valves 13, 17 open. Under the influence of the vacuum pump 4, a vacuum is created in the bubbler 3, and the electrolyte from the filling tank 1 through the valve 13 and the crosspiece 11 is squeezed out by atmospheric pressure in the liquid channel 22 of the first filling nozzle 20-1. installed on the A1 battery. Accumulator A1 is filled with electrolyte to a level corresponding to the level of the lower cut of the air channel 23, after which the electrolyte enters the liquid through this air channel and pipe 21

0 channel 22 of the second filling nozzle 20-2 installed on the accumulator A2. The whole process is then repeated until the last battery An is filled.

When the last battery is filled, 5 pa An electrolyte passes through the flow indicator 8, which records the end of the filling, while the control device 6 gives the command to close the valve 13, as a result of which the supply of electrolyte to the filling path is stopped. Thereafter

a command is given to open the atmospheric valve 12, with the excess electrolysis of the remaining electrolyte in the pipelines through the flow indicator 8, tee 10, valve 17 and three-way Esbrasyvets into the bubbler.

At the same time as excess electrolyte a, bzrboter 3, air saturated with electrolyte vapor enters through its inlet fitting. Since the inlet fitting has many small radial openings, the incoming air is divided into small jets, due to which it is more completely cleaned of electrolyte vapor when passing through a layer of oil.

The air thus purified, through the outlet nozzle of the bubbler 3, is sucked off by vacuum pump 4 and discharged into the atmosphere. In order to obtain a deeper air purification between the bubbler 3 and the vacuum pump 4, a dry filter can be installed using natural or synthetic material with a highly developed surface as an adsorbent,

During the impregnation of the plates and during the formation of the batteries, the vacuum pump 4 is in working condition, the valve 17 is constantly open, and the valve 12 periodically (after 3 ... 5 min) opens for a short (3 ... 5 s) time for the purpose of better impregnation of the plates of the batteries with electrolyte and for removal of the gases released during the formation of the batteries from the batteries.

When draining the spent electrolyte from the batteries, the rotary unit 5 is rotated 180 ° (in this case, the cut of the liquid channel of the filling fittings 20-1 ... 20p is lower than the cut of the air channel), after which, upon command from the control device 6, the vacuum pump 4 is turned on and the valves 16, 14, 19 are opened. In this case, the input and output of the filling nozzle system are switched and the atmospheric pressure through the atmospheric valve 19, tee 10 and flow indicator 8 is supplied to the air channel 23 of the last filling nozzle 20-p and through it fluid passage 22 pushes the first electrolyte battery of An, and then of all the subsequent ones. .

The electrolyte thus squeezed out through the crosspiece 11, the valve 14 and the flow indicator 7 is discharged into the sealed drain tank 2. Since the cut-off of the liquid channel of the filling nipple is made at the level of the cut-off of the filling hole of the battery, the electrolyte is drained almost completely.

The end of the drain is fixed by the flow indicator 7, after which the control device 6 issues a command to turn off the vacuum pump 4 and valves 14, 16, 19. The drain tank 2 is equipped with a device (for example, a level indicator or a float valve), which eliminates the possibility of the spent electrolyte entering the bubbler 3 through valve 16 and tee 9.

During the formation of the batteries, the filling and draining of the electrolyte can be carried out repeatedly; the continuous number of these cycles is determined by the volume of the drain tank 2.

The drain of the electrolyte from the drain tank 2 and the bubbler 3 is carried out by gravity with the valves 19, 17, 16 open, through the valves 15, 18 that are open at the time of the drain.

The electrolyte discharged from the bubbler 3 can be used without additional purification when refilling the batteries.

As indicators of electrolyte flow, for example, electro-, opto- or vacuum sensors can be used.

Thus, the use of the proposed device allows filling the batteries to the required level and completely draining the spent electrolyte, practically eliminating the electrolyte overrun, prolonging the life of the vacuum pump and reducing harmful emissions into the atmosphere.
