Abstract
A battery cleaning system and process are provided, that make it possible to clean high capacity (12 to 72) volt acid storage batteries using appropriate cleaning solutions and liquids while recovering, cleaning and recycling the washing waste liquids, and minimizing the volume of liquid that has to be discarded.
Claims9
An environmentally-acceptable high-capacity acid storage battery cleaning system for industrial and commercial electric motor vehicles whose batteries accumulate external contaminants in use, comprising, in combination:
- (1) a foraminous platform support for a dirty battery;
- (2) cleaning means for applying an aqueous cleaning solution containing (a) active cleaning detergent and (b) alkaline buffer, wherein the aqueous cleaning solution has a pH of at least 8, under a pressure within the range from about 0.5 to about 30 psi to a dirty battery on the support;
- (3) means for collecting dirty aqueous cleaning solution containing dirt and contaminant material suspended therein and draining from the battery and foraminous platform support after application to the battery;
- (4) filter means for removing suspended dirt and contaminant material from the dirty aqueous cleaning solution;
- (5) pump means for circulating cleaning solution to and clean filtrate from the filter means to the cleaning means;
- (6) rinsing means for applying rinsing water under a pressure within the range from about 800 to about 2500 psi to the battery after cleaning;
- (7) means for collecting dirty rinsing water from the rinsing;
- and
- (8) pump means for circulating dirty rinsing water to the filter means or to the cleaning means, selectable according to the dirtiness of the rinsing water.
