Abstract
A process for making a battery paste includes steps of forming an active material in an aqueous slurry, then dewatering the slurry to form a battery paste. In one described embodiment, a slurry containing one or more basic lead sulfates suitable for use as the active material in lead-acid battery electrodes is formed in a continuously stirred tank reactor (36). The slurry is withdrawn from the reactor (36) and fed to a belt press (67) which reduces the moisture content of the slurry to the desired level. Battery pastes produced according to the invention may be fed continuously to a paster (89) for mass production of positive and negative battery plates from grids (91).
Claims12
An apparatus for producing a battery paste material, comprising:
- a tank having a discharge outlet;
- a feeder disposed to feed a particulate solid into the tank;
- an inlet disposed to introduce water into the tank to form a mixture with the particulate solid;
- a conveyor having a porous conveyor belt disposed to receive the mixture from the discharge outlet of the tank on a surface of the porous conveyor belt;
- a filtration device capable of drawing a portion of the water from the mixture through the porous conveyor belt to form a paste material;
- and
- a paster disposed to receive paste from the filtration device and apply the paste to a series of grids.
