Abstract
The present invention relates to the removal of grease collected in a hydro-mechanical grease interceptor via a pump which may be activated by a programmable timer. In an embodiment, a hydro-mechanical grease interceptor includes a tank having a tank inlet and a tank outlet; a tray positioned inside the tank; and a pump located inside the tank, the pump having a pump inlet and a pump outlet, wherein the pump inlet is located within the tray at a level below the tank outlet. The interceptor may include a timer coupled to the pump to control operation of the pump.
Claims20
A hydro-mechanical grease interceptor comprising:
- a tank having a tank inlet and a tank outlet;
- a tray positioned inside the tank;
- and
- a pump located inside the tank, the pump having a pump inlet and a pump outlet, wherein the pump inlet is located within the tray at a level below the tank outlet.
A timed grease evacuation system comprising:
- a tank comprising a tank inlet and a tank outlet;
- a baffle positioned in the tank between the tank inlet and the tank outlet;
- a flow passage below the baffle;
- an elevated tray positioned in the tank between the baffle and the tank outlet;
- a pump supported by the elevated tray, the pump having a pump inlet below a pump outlet, wherein the pump inlet is positioned by the elevated tray below the tank outlet;
- a timer coupled to the pump and programmable to operate the pump at timed intervals;
- a reclaim tank;
- and
- an evacuation hose connecting the reclaim tank to the pump outlet.
A hydro-mechanical grease interceptor for collecting grease, comprising:
- an inlet chamber;
- a separation chamber separated from the inlet chamber by a baffle;
- an elevated tray positioned in the separation chamber;
- a pump supported by the elevated tray;
- and
- a timer programmable to operate the pump at programmed intervals,
- wherein the pump is positionable in the elevated tray to draw such grease upward from the elevated tray.
A method of evacuating grease from a hydro-mechanical grease interceptor, comprising:
- providing a hydro-mechanical grease interceptor having a chamber;
- passing grease-containing water into the chamber;
- activating a pump after a preselected period of time to draw grease into a tray within the chamber and to evacuate the grease to a reclaim tank;
- continuing to pass grease-containing water into the interceptor;
- and
- periodically re-activating the pump.
