Chemical mixing and dispensing system
First Claim
1. An apparatus for mixing and dispensing chemical solutions, comprising:
- (a) a manifold having a main passage, a plurality of chemical inlet ports connected to said passage, an outlet port connected to said passage, and a water inlet port connected to a source of pressurized water;
(b) a plurality of pumps which are selectively controllable, one of said pumps being connected to each of said chemical inlet ports so as to pump a chemical solution therethrough;
(c) selectively controllable valve means associated with each said chemical inlet ports;
(d) a dispensing outlet connected to said outlet port for dispensing said chemical solutions and water into a container; and
(e) quality control means for determining whether the proper chemical solutions have been dispensed, wherein said quality control means comprises;
(i) means for repeatedly measuring the conductivity of the chemical solutions flowing through said main passage of said manifold to produce a conductivity output; and
(ii) means for comparing said conductivity output with a standard conductivity output.

Abstract
An apparatus and method for mixing and dispensing chemical solutions are disclosed. The blending unit (11) includes a manifold (38) having a plurality of chemical inlet ports (39), a water inlet port (45), and an outlet port (46). A plurality of pumps (43) and valves (41) are associated with the chemical inlet ports (39). The outlet port (46) is connected to dispensing outlets (25, 29) for dispensing the chemical solutions and water into a container 16. The apparatus (10) also includes a quality control systems, including a conductivity cell (50), a weight measurement station (26), and a volume flow measurement device. The apparatus (10) also includes an electronic control unit (70) associated with the pumps (43) and valves (41) to operate them in response to a pre-selected volume, sequential combination and concentration of chemicals.
