Abstract

Abstract An automatic dump system for use with a slurry processing sump is disclosed. It has a flushing chamber and a collection chamber attached to the lower end of the sump. A flushing fluid is supplied to the flushing chamber to deflect relatively heavy contaminating materials into the collection chamber, and provide resistance to settlement of relatively light slurry materials. Both the flushing chamber and the collection chamber have valves which are controlled by an actuation means to periodically discharge collected contaminating materials without interrupting sump operation.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 171 words
A dump system for discharging contaminants collected by a slurry processing sump, said dump system comprising: a. a flushing chamber attached to the bottom of said sump, said flushing chamber having a fluid intake end; b. a collection chamber adjacent said flushing chamber, said collection chamber having a discharge end and having an inlet end connected to said flushing chamber; c. a dispersion means disposed in said flushing chamber intermediate of said fluid intake end of said flushing chamber and said collection chamber inlet end; d. means for introducing a flushing fluid to said fluid intake end of said flushing chamber and directing said flushing fluid through said dispersion means to deflect the contaminants into said collection chamber and for keeping the relatively lighter slurry materials from settling; e. a normally closed valve means at said discharge end of said collection chamber for controlling flow of said flushing fluid and said contaminants there through; and f. a normally open valve means in said flushing chamber above said collection chamber inlet end.
Claim 2
Dependent Claim 171 words
A dump system for discharging contaminants collected by a slurry processing sump, said dump system comprising: a. a flushing chamber attached to the bottom of said sump, said flushing chamber having a fluid intake end; b. a collection chamber adjacent said flushing chamber, said collection chamber having a discharge end and having an inlet end connected to said flushing chamber; c. a dispersion means disposed in said flushing chamber intermediate of said fluid intake end of said flushing chamber and said collection chamber inlet end; d. means for introducing a flushing fluid to said fluid intake end of said flushing chamber and directing said flushing fluid through said dispersion means to deflect the contaminants into said collection chamber and for keeping the relatively lighter slurry materials from settling; e. a normally closed valve means at said discharge end of said collection chamber for controlling flow of said flushing fluid and said contaminants there through; and f. a normally open valve means in said flushing chamber above said collection chamber inlet end.
Claim 3
Dependent Claim 81 words
The dump system of claim 1 including actuation means connected to both of said valve means and constructed and arranged to operate both of said valve means in such manner that flow from said flushing chamber to the sump is stopped and flow out said discharge end of said collection chamber is started, said actuation means including control means constructed and arranged to open and close said normally closed valve means and to open and close said normally open valve means.
Claim 4
Dependent Claim 95 words
An automatic dump system for discharging contaminants collected by a slurry processing sump as claimed in claim 2 wherein each of said normally open and normally closed valve means comprises: a. a housing b. a bellows sleeve within said housing, said sleeve being formed of deformable material and adapted to provide an annular actuation chamber between said sleeve and said housing; and c. a port formed in said housing for either applying fluidic pressure to said actuation chamber to pinch said sleeve closed or applying a vacuum to said actuation chamber to open said sleeve.
Claim 5
Dependent Claim 49 words
An automatic dump system for discharging contaminants Collected by a slurry processing sump as claimed in claim 1, said system further comprising sensing means mounted on said collection chamber for providing a signal to said actuation means when the contaminants collected within said collection chamber need to be discharged.
Claim 6
Dependent Claim 43 words
An automatic dump system for discharging contaminants collected by a slurry processing sump as claimed in claim 1, said system further comprising a timing device connected to said actuation means to periodically cycle said system to discharge the contaminants collected within said system.
Claim 7
Dependent Claim 34 words
An automatic dump system for discharging contaminants collected by a slurry processing sump as claimed in claim 1 wherein said dispersion means comprises an angularly disposed plate having an array of apertures formed therein.
Claim 8
Dependent Claim 40 words
An automatic dump system for discharging contaminants collected by a slurry processing sump as claimed in claim 1 wherein said dispersion means comprises a plug formed co-axially with said flushing chamber, said plug having a plurality of apertures formed therein.
Claim 9
Dependent Claim 110 words
An automatic dump system for discharging contaminants collected by a slurry processing sump as claimed in claim 1, wherein said actuation means comprises: a. a control means coupled to said actuation means for proper sequencing thereof; b. a source of fluidic pressure coupled to said actuation means; c. an aspirator controlled by said control means for providing a vacuum within said actuation means; and d. a plurality of solenoid valves coupled to said source of pressure and said aspirator, said solenoid valves also being coupled to the automatic dump system to selectively apply either vacuum or pressure to the dump system, said solenoid valves being controlled by said control means.
Claim 10
Dependent Claim 131 words
An automatic dump system for discharging contaminants by a slurry processing sump as claimed in claim 1, wherein said actuation means comprises: a. a control means coupled to said actuation means for sequencing thereof; b. a source of fluid pressure coupled to said actuation means; c. a selectively operable aspirator for providing a vacuum within said actuation means; d. a first solenoid valve coupled to said normally open valve means, said first solenoid valve adapted to selectively apply either pressure or vacuum to said normally open valve means under control of said control means; and e. a second solenoid valve coupled to said normally closed valve means, said second solenoid valve adapted to selectively apply either pressure or vacuum to said normally closed valve means under control of said control means.
