Explosion-proof vent barrel for a battery

Patent ·
OSTI ID:7315446

An explosion-proof vent barrel has a tubular body, an electrolyte splash baffle, and an electrolyte drain funnel molded integrally with one another, there being a porous flame-arresting disc telescoped into the body. Three barrels are ganged on a common frame which protects the flame-arresting discs against dirt and grease. In one embodiment, the underside surface of the frame is formed with a shallow channel to permit positive venting of the gases which diffuse through the arrestor discs. In another embodiment, both the discs and barrels are maintained in closely spaced relation to the underside of the frame for defining a positive escape area about substantially the entire periphery of the disc. In each instance, the depth of the positive vent escape area does not exceed 0.015 inches, so as to permit positive venting while retarding the entrance of a flame into the space between the disc and frame. 6 figures.
