Abstract
A portable parts washer flows a washing agent over an object to remove any contaminants. The washing agent and contaminants flow into a basin mounted below the object. The washing agent is drawn from the basin and used to wash the object to provide a closed-loop system. A venturi-type injector mixes ozone from an ozone generator with the washing agent. A pump draws the washing agent from a first inlet to the basin, forces the washing agent through the injector, and returns the washing agent through a first outlet to the basin.
Claims32
An apparatus for washing an object having a contaminant and for recovering the contaminant, comprising:
- a floor arranged to support said object;
- a flowing mechanism for flowing a washing agent over said object to remove said contaminant;
- a basin mounted below said floor for receiving said washing agent and said contaminant, said basin including a plurality of interconnected compartments including at least one receiving chamber arranged to receive the washing agent after it has been flowed over the object, and at least one staging chamber that does not directly receive the washing agent after the washing agent has been flowed over the object but is in fluid communication with the receiving chamber, the plurality of compartments being arranged such that the washing agent generally becomes less contaminated as the washing agent passes from the at least one receiving chamber to the at least one staging chamber, said flowing mechanism drawing said washing agent from said basin to form a substantially closed loop;
- an ozone generator;
- a gas-liquid mixer connected to said ozone generator to inject ozone into said washing agent;
- a first pump for drawing said washing agent from the at least one staging chamber, forcing said washing agent through said mixer, and returning said washing agent through a first outlet to said basin.
An apparatus for washing an object having a contaminant said apparatus further being arranged to recover the contaminant, the apparatus comprising:
- a flowing mechanism for flowing a washing agent over said object to remove said contaminant;
- a basin mounted below said object, said basin being arranged to receive said washing agent and said contaminant, wherein said flowing mechanism is arranged to draw said washing agent from said basin to form a substantially closed loop;
- an ozone generator;
- a gas-liquid mixer connected to said ozone generator, said gas-liquid mixer being arranged to inject ozone into said washing agent;
- a first pump arranged to draw said washing agent from a first inlet to said basin, the first pump further being arranged to force said washing agent through said mixer and to return said washing agent through a first outlet to said basin, said basin including a plurality of baffle walls which define a circulation path between said inlet and said outlet;
- and
- a contaminant isolator, wherein the contaminant isolator is positioned in said circulation path.
A self-contained pressure washing apparatus for washing an object having a contaminant, said apparatus further being arranged to recover the contaminant, the apparatus comprising:
- a floor arranged to support the object;
- a flowing mechanism for flowing a washing agent over said object to remove said contaminant, the flowing mechanism including a pressure washer, the pressure washer being arranged to produce a high pressure stream of the washing agent;
- a basin mounted below said object, said basin being arranged to receive said washing agent and said contaminant, wherein said flowing mechanism is arranged to draw said washing agent from said basin to form a closed loop;
- an ozone generator;
- a gas-liquid mixer connected to said ozone generator, said gas-liquid mixer being arranged to inject ozone into said washing agent;
- and
- a first pump arranged to draw said washing agent from a first inlet to said basin, the first pump further being arranged to force said washing agent through said mixer and to return said washing agent through a first outlet to said basin, said basin including a plurality of baffle walls which define a circulation path between said inlet and said outlet, the baffle walls further defining a plurality of compartments, wherein said circulation path includes a plurality of gaps interconnecting said compartments.
