Abstract
The invention is a device which uses stored pressure to pump waste and a corresponding method of use. Waste is stored in a first chamber and the chamber is subsequently sealed by a valve and pressurised prior to a second valve opening. The pressurised waste is thereby ejected from the pressure chamber down an outlet pipe.
Claims20
A pumping device for pumping waste, comprising
- a waste chamber, for storing waste, having an inlet for receiving waste and an outlet for transmitting waste;
- a pump connected to the waste chamber;
- a first valve for controlling received waste from the waste chamber inlet;
- and
- a second valve for controlling transmitted waste through the waste chamber outlet;
- wherein
- the pump is operable to increase pressure within the waste chamber when the first and second valves are closed;
- and
- the waste is forced from the waste chamber through the second valve by the pressure within the waste chamber when the second valve open is opened.
6 more elements
A method of pumping waste comprising the steps:
- (i) opening a first valve to enable waste to flow into a waste chamber and closing a second valve to stop waste flowing out of the waste container;
- (ii) closing the first valve to stop waste flowing into the waste chamber;
- (iii) increasing the pressure within the waste chamber to be greater than the pressure outside the waste chamber using a pump;
- and
- (iv) opening the second valve to enable waste to flow out of the waste chamber.
