Abstract
The utility model discloses a lead calcium alloy grid surface and aging treatment device for a lead-acid battery. The device includes a closed room, a grid for a storage battery, a heating device, an acetic acid water solution spray pipe, a thermometer and a hygrometer, and a circulating fan. According to the utility model, the lead on the grid surface is subjected to effective corrosion by the acetic acid and carbon dioxide in advance, which improves the binding force between the grid and lead paste, can significantly improve the conductivity of the interface of the grid and an active material, and improves deep cycle capability of the lead-acid battery. Simultaneously, reasonable choice of the temperature, humidity and time shortens the grid aging treatment time and improves production efficiency, with the aging time decreased to about 4h from original 5 days at room temperature.
Description
Technical field
The utility model relates to the lead-acid cell field, is specifically related to the device that a kind of lead storage battery is used lead-calcium alloy slab lattice surface and timeliness hardening treatment.
Background technology
For promoting China's lead storage battery adjustment of industrial structure and industrial upgrading; the investment behavior of standard industry; prevent low-level duplicate construction; preserve the ecological environment; improve comprehensive utilization of resources efficient; national environmental protection portion and Ministry of Industry and Information just send the exposure draft of " lead storage battery industry access condition " from the first half of the year in 2011, have put into effect authorized documents in May, 2012, and this document requires to rise July 1 from this year execution.This document is clear and definite regulation, in by the end of December, 2013 before, cadmium content is higher than 0.002% lead storage battery will be eliminated.Present domestic electric vehicle lead storage battery is to make grid with the Pb-Sb-Cd alloy material (grid is the carrier of active substance basically, play electric action simultaneously), that is to say that the task of top priority now is to find the alloy material that can replace Pb-Sb-Cd alloy can satisfy electric vehicle lead storage battery purposes again.The common lead calcium alloy extensively has been used in the discharge probability lead storage batterys seldom such as fixed and UPS uninterruptible power supply now, but this alloy is not suitable for the lead storage battery of dark circulation and long lifetime purposes.Shortcoming behind the employing lead-calcium alloy is exactly that cycle life is short, it is grid surface corrosion difficulty that end causes the reason of this phenomenon, be combined bad with the interface of active substance, form the blocking layer of electronics, alleged " no antimony effect " (contain the antimony grid and do not have capacity early ageing, the problem that causes battery life to lack) in our industry just.Power truck is the industry of national encourage growth always, if still can not find ways of addressing this issue, lead storage battery just faces and withdraws from power truck market, has so just seriously restricted the development of power truck industry.
The utility model content
The purpose of this utility model is at problems of the prior art and deficiency, a kind of bonding force that can significantly improve grid and active substance is provided, improve electroconductibility, thereby reach the efficient apparatus of dark cycle battery requirement in work-ing life, this device can also shorten to 4h from 7 days with the grid aging time, can significantly improve production efficiency.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
The device that a kind of lead storage battery is handled with lead-calcium alloy slab lattice surface and timeliness, comprise closed room, in closed room, be provided with the store battery grid, in closed room, be provided with heating unit, and at the closed room inner side-wall thermo detector and wet bulb thermometer are installed, and be provided with recirculation blower at the top of closed room simultaneously, be connected with blast main on the recirculation blower, branch wind pipe is straight up arranged respectively around in the closed room inboard, and each branch wind pipe is communicated with blast main.On the closed room inner side-wall, also be provided with acetic acid aqueous solution and spray pipeline.Described heating unit is electrically heated or steam heater.
The utility model adopts technique scheme, and it is such obtaining unusual effect:
1. the utility model can solve and the thickening of grid surface corrosion layer can be increased grid with the contact area of active substance, improves the bonding force of grid and active substance, thus extending battery life.
2. under hot environment, grid is handled through age hardening, improves the crystalline-granular texture of lead-calcium alloy, improves grid hardness (being convenient to follow-up machine coated plate technology), can also improve the electrochemical corrosion resistant ability of grid simultaneously, the cycle life that has prolonged battery relatively.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Fig. 1 is the vertical planning drawing in the used room of the utility model treatment unit;
Fig. 2 is the vertical view in the used room of the utility model treatment unit.
Embodiment
As depicted in figs. 1 and 2, the device that lead storage battery is handled with lead-calcium alloy slab lattice surface and timeliness is to be provided with store battery grid 4 in closed room 1, in closed room, be provided with heating unit 5, on the closed room inner side-wall, also be provided with acetic acid aqueous solution and spray pipeline 9.Heating unit 5 can be electrically heated or steam heater.And at closed room 1 inner side-wall thermo detector 8 and wet bulb thermometer 10 are installed, simultaneously be provided with recirculation blower 2 at the top of closed room, be connected with blast main 6 on the recirculation blower 2, branch wind pipe 3 is straight up arranged respectively around in the closed room inboard, each branch wind pipe 3 is communicated with blast main 6, and the air outlet tube of recirculation blower 2 is dried in closed room 1 by branch wind pipe 7.In the entire treatment process, the gate 11 in room 2 remains closing condition, after finishing to processing, can open the gate, is cooled to take out grid after the room temperature and get final product.
Claims (3)
1. the device handled with lead-calcium alloy slab lattice surface and timeliness of a lead storage battery, comprise closed room, in closed room, be provided with the store battery grid, it is characterized in that: in closed room, be provided with heating unit, and at the closed room inner side-wall thermo detector and wet bulb thermometer are installed, and be provided with recirculation blower at the top of closed room simultaneously, be connected with blast main on the recirculation blower, branch wind pipe is straight up arranged respectively around in the closed room inboard, and each branch wind pipe is communicated with blast main.
