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.
A chemical dispersing apparatus comprising a vertical upright cylindrical container having an integral bottom and a flanged and bolted top main cover, for containing chemicals;
A chemical dispersing apparatus comprising a cylindrical container having an integral bottom and a removable top main cover for containing chemicals;
A method of selectively dispersing chemicals from a container having an inlet nozzle and an outlet nozzle and containing at least one cylindrical screen, said container and said screen defining an annular space surrounding said screen, said method comprising the steps of placing the chemicals in said annular space of said container, introducing a liquid into said container through said inlet nozzle at a selected flow rate and contacting said chemicals with the liquid in a radial and up-flow axial-radial flow pattern of the liquid to at least partially dissolve, admix or displace said chemicals in the liquid, whereby pressure within said container increases until it equalizes with the pressure of the liquid to define a pressurized liquid treatment stream;
