Foam generation apparatus
A foam generation apparatus is claimed. The apparatus includes a housing defining an interior portion and two ports disposed on an exterior surface of the housing. One of the ports is adapted to receive chemical into the interior portion of the housing, and another of the ports is adapted to receive compressed air into the interior portion of the housing. The apparatus also includes coarse threads integrally molded at a top portion of the housing. Finally, the apparatus includes an insert that includes a cap, a rod extending from an interior portion of the cap, and one or more agitation balls affixed to the rod. Like the housing, the cap also includes coarse threads formed therein. As such, the insert is disposed within the housing and secured to the housing by way of the coarse threads of the insert and the housing.
1. A foam generation apparatus comprising:
a housing defining an interior portion;
two ports disposed on an exterior surface of the housing, one of the ports adapted to receive chemical into the interior portion of the housing, another of the ports adapted to receive compressed air into the interior portion of the housing;
coarse threads integrally molded at a top portion of the housing; and,
an insert comprising a cap, a rod extending from an interior portion of the cap, and one or more agitation balls affixed to the rod, the cap comprising coarse threads formed therein, the balls each comprising multiple fins with each ball having been formed of non-corrosive material,
the insert being disposed within the housing and secured to the housing by way of the coarse threads of the insert and the housing.
2. The apparatus of claim 1 , wherein fibrous pads also are affixed to the rod along with the agitation balls.
3. The apparatus of claim 1 , wherein an end of the housing opposite the coarse threads comprises molded female threads adapted for coupling to a equipment receiving foam discharges from the housing.
4. The apparatus of claim 1 , wherein the rod is threaded and positioned within an opening in the cap with a portion of the rod extending beyond an exterior portion of the cap, and wherein a neoprene washer and a non-corrosive lock nut are affixed to threads on the portion of the rod extending beyond the exterior portion of the cap.
5. The apparatus of claim 1 , wherein a gasket is disposed within a molded gasket retainer in the cap.
