| 摘要 |
This invention relates to an improved stationary slurry distributor characterized by a centrally-located standpipe to receive the incoming slurry, a multi-apertured manifold at the base of the standpipe for continuously distributing the contents of the latter into a plurality of separate compartments bordering the periphery thereof, outlets in the bottom of each compartment, stopper-type valves independently operable to plug one of the outlets, and at least one overflow port in the side of each compartment arranged in misaligned relation to the inlet and slurry stream issuing therefrom, these ports being effective to both prevent the escape of the slurry therethrough when the outlet is open and, alternatively, bypass the flow when the outlet from the compartment is closed so as to not increase the flow into and through the other compartments then in use. The invention also encompasses the novel mechanism for guiding the stopper valve during its excursions between open and closed positions that also provides a subassembly for maintaining it in coaxial alignment with its seat. An adjustable coupling also connects each valve to its actuator for effecting axial adjustment of the valve relative to its seat. The invention also encompasses the novel flow control method which includes the step of bypassing the input into any compartment with its outlet closed so as to not increase the flow into those with open outlets.
