ABSTRACT:
A device for dispersing solid, powder, granular, tablet or liquid forms of beneficial chemical(s) into a pressurized liquid stream, distributing variable quantities over adjustable time in variable concentrations of dispersed chemical(s) through other ancillary connected equipment, permitting dispensing of the resultant fluid of pressurized beneficial chemical(s) for treatment of living or growing matter, including: foliage, plants, trees, crops, shrubs, weeds, grass, fungi and insects to achieve a useful or beneficial purpose. The device includes an upright, vertical cylindrical container constructed in capacities from less than 1 gallon to 1000 gallons and fitted with one or more internal screens to obstruct the escape of solid particles of a specific size into the product liquid stream. The design permits fresh supply liquid to contact chemical(s) in radial and upflow axial-radial flow patterns.
The container and attachments are designed to withstand high fluid pressures [up to 200 psig] without rupture or leakage. The device is connected to other installed in-ground pipes attached to spraying nozzles, sprinklers or sprinkler systems or flexible loose hoses or rigid pipe lying on the ground and further attached to sprayer devices such as hand-held nozzles, sprinklers, sprayers or spargers to be used manually, in semi-automatic or in fully automatic modes to disperse chemical(s). The device, which is formed from metal and/or thermal plastic materials and elastomers, uses valves to regulate chemical dispersement.
