Abstract
Description
Claims (13)
- A waste disposal unit for collecting waste liquid entrained with particles from a waste 1iquid source, comprising: a tank for collecting waste liquid having an access that when closed creates a substantially sealed environment in the interior of the tank; a vacuum pump in communication with the tank interior for creating a low pressure in the tank interior; a vacuum tube coupled to the vacuum pump and extending upwardly through the tank interior with an open end of the vacuum tube facing upwardly in the tank interior to draw air from an upper end of the tank interior; a delivery hose sealingly coupled to the tank interior to draw liquid from the waste liquid source to the tank interior when the pressure in the tank interior is lower than the pressure at the waste liquid source; and means for protecting against liquid entering the vacuum tube.
- The waste disposal unit claimed in claim 1, wherein the means for protecting against liquid entering the vacuum tube includes the placement of an outlet of the delivery hose at an opposite side of the tank interior to the vacuum tube.
- The waste disposal unit claimed in claim 1 or claim 2, wherein the means for protecting against liquid entering the vacuum tube includes a shroud surrounding the open end of the vacuum tube.
- The waste disposal unit claimed in claim 2 or claim 3, wherein the open end is located close to the underside of the access, which is a lid. Received at IPONZ 24 February 2012 - 11 -
- 5. The waste disposal unit claimed in any one of the preceding claims, wherein the vacuum pump is located on a lower exterior of the tank and the vacuum tube 5 sealingly passes upward through a bottom wall of the tank.
- 6. The waste disposal unit claimed in any one of the preceding claims, comprising a discharge pump connected to a discharge conduit for transferring the 10 waste liquid out of the tank.
- 7. The waste disposal unit claimed in claim 6, wherein the discharge pump draws waste liquid from an exit hole in the bottom wall of the tank and transfers waste liquid through the discharge conduit. 15
- 8. The waste disposal unit claimed in any one of the preceding claims, wherein the delivery hose is rigidly curved where the hose couples with the tank.
- 9. The waste disposal unit claimed in claim 8, wherein the delivery hose has a diameter of between 20mm to 20 7 0mm.
- 10. The waste disposal unit claimed in any one of the preceding claims wherein the other end of the delivery hose to the tank is provided with a nozzle having a diameter smaller than the diameter of the delivery 25 hose.
- 11. The waste disposal unit claimed in claim 10, wherein the diameter of the nozzle is between 30mm and 40mm.
- 12. The waste disposal unit claimed in any one of the preceding claims, including a strainer positioned in 30 the tank to strain waste liquid as it enters the tank from the delivery hose.
- 13. The waste disposal unit claimed in any one of the preceding claims, including controls and a level indicator to stop operation of the vacuum pump when Received at IPONZ 24 February 2012 - 12 - the level of waste liquid in the tank reaches a predetermined value. A method of collecting waste liquid entrained with particles from a waste liquid source using a waste disposal unit, including: inserting a delivery conduit into a waste liquid source, the delivery conduit being sealingly coupled to a tank of the waste disposal unit; activating a vacuum pump that is in communication with an interior of the tank to create a low pressure in the tank interior; a vacuum tube being coupled to the vacuum pump and extending upwardly through the tank interior with an open end of the vacuum tube facing upwardly in the tank interior to draw air from an upper end of the tank interior; drawing waste 1iquid through the delivery conduit and into the tank interior by way of the pressure in the tank interior being lower than the pressure at the waste liquid source; and protecting against liquid entering the vacuum tube. The method claimed in claim 14, comprising: discharging waste 1iquid from the tank by pumping the waste liquid through an exit hole in a lower portion of the tank and out through a discharge conduit. The method claimed in claim 14 or 15, including protecting against liquid entering the vacuum tube by locating the delivery conduit in the tank interior at an opposite side of the tank to the open end of the vacuum tube, or by providing a shroud surrounding the open end of the vacuum tube. A waste disposal unit or a method of collecting waste liquid, substantially as herein described with reference to the accompanying drawings.
