ABSTRACT:
A chemical blending system having more than one chemical blending vessel (12, 12') with inlets at the top. A pair of automatic inlet valves are connected to the top of each chemical blending vessel, one with a large inlet orifice and one with a relatively much smaller inlet orifice. At least two chemical batch tanks are connected to the pair of automatic inlet valves and chemicals to be mixed are delivered there at high speed by pumps. Weight cell devices (30) are attached to the bottom of each blending vessel. A controller/computer is connected for the automatic control of pumps (28, 36) and valves (20, 50, 58). A discharge line is connected to the bottom of blending vessels and to a receiving station, and includes pulsation dampeners (38), filters (40) and static mixers (42). A sampling device (46) is connected a recirculation line for the sampling of the blended chemical during recirculation and prior to delivery. Drain valve and drain line are connected to the bottom of the blending vessel for the draining and delivery of unused chemical to remote recovery tank (54). When one blending vessel is delivering appropriately blended chemical, another chemical blending vessel is being filled so that an essentially continuous, uninterrupted supply of appropriately and quickly blended chemical is available.
