Abstract
A system wherein an ultrasound emitter, or gun, is provided which emits an ultrasound beam directed at filter media, on the opposite side of the filter media from where solids accumulate, in order to knock the solids from the filter media. Dislodged solids from the area targeted by the beam are driven upstream, away from the filter media. Gravity then draws the solids to a drain of a collection chamber, which allows for the solids to be safely removed from the system. A guide is provided upstream of the filter media, the guide having angled slats or vanes. These vanes are angled upwardly towards the filter media and downwardly towards the drain, such that as the solids are blasted from the filter media by the gun, they are jolted upstream, and impact the angled vanes upon their downstream return.
Claims21
A filtration system for filtering material from a flow of a fluid, the filter system comprising:
- a first chamber for receiving fluid, and a second chamber for receiving fluid from said first chamber;
- said first chamber defining an inlet for receiving fluid therein, and said second chamber defining an outlet for dispensing fluid therefrom;
- a filter for receiving flow of the fluid therethrough and disposed between said first and second chambers, said filter having an upstream side adjacent said first chamber and a downstream side adjacent said second chamber;
- said upstream side of said filter being configured to collect material from the fluid as the fluid flows through said filter;
- and
- at least one ultrasonic transducer configured for directing an ultrasonic beam upon said downstream side of said filter of a force sufficient to dislodge and force upstream material collected on said upstream side of said filter.
A method of filtering material from a flow of a fluid, the method comprising:
- providing a filter for receiving flow of the fluid therethrough, said filter having an upstream side and a downstream side;
- said upstream side of said filter being configured to collect material from the fluid as the fluid flows through said filter;
- providing at least one ultrasonic transducer configured for directing an ultrasonic beam upon said downstream side of said filter;
- and
- directing said ultrasonic beam of said ultrasonic transducer against said downstream side of said filter with a force sufficient to dislodge material which may collect on said upstream side of said filter.
A filtration system for filtering material from a flow of a fluid, the filter system comprising:
- a first passage for receiving fluid, and a second passage for receiving fluid from said first passage;
- said first passage defining an inlet for receiving fluid therein, and said second passage defining an outlet for dispensing fluid therefrom;
- a filter for receiving flow of the fluid therethrough and disposed between said first and second passages, said filter having an upstream side adjacent said first passage and a downstream side adjacent said second passage;
- said upstream side of said filter being configured to collect material from the fluid as the fluid flows through said filter;
- at least one ultrasonic transducer configured for directing an ultrasonic beam upon said downstream side of said filter with a force sufficient to dislodge material collected on said upstream side of said filter;
- and
- means for moving said ultrasonic transducer with respect to said filter.
