Abstract
The speed, effectiveness, and convenience with which pallets and other objects are cleaned can be increased by using a pressure power-washing apparatus described. The apparatus includes at least one pressure-washer that pumps liquid from a tank into rotary arms within a cleaning chamber, causing the rotation of the arms as the arms eject streams of the liquid pumped under a high pressure from angled nozzles. Conveyors carry an object in need of cleaning into the cleaning chamber, first exposing the object to the streams of the liquid, and then to a drying chamber. Guide rails positioned on the platform guide the object during cleaning, with the shape of one of the guide rails causing the object to fall off following the drying to remove excess liquid left on the object.
Claims20
A pressure-washing apparatus, comprising:
- a liquid tank;
- one or more pressure washers connected to the liquid tank, each pressure washer comprising a motor and a high-pressure pump that is driven by the motor and that pumps liquid from the liquid tank into one or more connections under a high pressure;
- a cleaning chamber, comprising:
- two walls;
- one or more swivel heads attached to each of the walls, each of the swivel heads comprising an end connected to one of the connections and an opposite end comprising a rotatable hollow shaft;
- one rotary arm mounted on each of the swivel heads, each of the arms comprising a hollow rotatable bar set onto the rotatable hollow shaft, each of the hollow bars comprising a substantially straight central portion and a bent portion formed on each of the ends of the substantially straight central portion, wherein the bent portions are offset from the substantially straight central portion with respect to two axis, each of the arms further comprising a spray nozzle mounted upon an end of each of the bent portions of the hollow bar and angled relative to the substantially straight central portion in the two axis, the angled spray nozzles pointing into different directions, wherein the pump pushes the liquid through the connection connected to that swivel head through the hollow bar of that arm, and through the angled spray nozzles of that arm, causing an ejection of the liquid from the angled spray nozzles of that arm in a plurality of streams directed at least a portion of time at an object within the cleaning chamber, and wherein the ejection of the streams from the angled spray nozzles causes a rotation of that arm and the rotatable hollow shaft upon which the hollow rotatable bar of that arm is set;
- and
- a plurality of conveyors that carry the object in, through, and out of the cleaning chamber, the object having a plurality of surfaces, the surfaces comprising a bottom surface, a top surface, and side surfaces, wherein two of the plurality of the conveyors are separated by a gap, wherein the liquid ejected from one or more of the angled spray nozzles hits at least a portion of the bottom surface of the object when the object passes over the gap and wherein the liquid ejected from one or more of the angled spray nozzles hits at least a portion of each of the remaining ones of the plurality of surfaces of the object as the object is carried through the cleaning chamber by one or more of the plurality of conveyors.
