Abstract
Abstract A portable cleaning apparatus for removing solids and particulate material from water in the basin of a cooling tower and having a trailer with a frame supporting a platform and a plurality of wheels for enabling said trailer to be towed from place to place, a power driven pump means mounted on said platform and having a suction side adapted to be placed into communication with water contaminated with solids in the basin of a cooling tower, a filter device arranged on said platform and including a filter medium therein, an inlet for liquid influent connected to the pump outlet and an effluent outlet downstream of the filter medium, the filter medium being so constructed and arranged as to retain solid particles thereon whose diameter is in excess of 0.375 inches, a bank of a plurality of hydrocyclone separators located on said platform and including a feed header in communication with the feed inlet of each hydrocyclone, an outlet header being connected to the overflow discharge of each hydrocyclone, said filter effluent outlet being connected to said feed header, and said outlet header recirculating clarified effluent back to the basin of said cooling tower, a sediment solids tank arranged on said platform and with said filter device having a solids discharge outlet in communication with said tank, each of said hydrocyclones including underflow discharge means in communication with said tank, and auger means having an inlet located within said tank and an outlet adapted to discharge solids outside said tank.

Claim 1
Independent Claim
362 words
A portable cleaning apparatus for removing solids and particulate material from water in the basin of a cooling tower and comprising: a trailer having a frame supporting a platform and a plurality of wheels for enabling said trailer to be towed from place to place; a power driven pump mounted on said platform and having an outlet and a suction side adapted to be placed into communication with solids in the basin of a cooling tower: a filter device arranged on said platform and including a filter tank having a filter medium disposed therein to divide said filter tank into an influent chamber and an effluent chamber, an inlet for liquid influent connected to the pump outlet connected to said tank to deposit liquid influent into said influent chamber, and an effluent outlet connected to said effluent chamber, the filter medium being so constructed and arranged so as to retain solid particles thereon whose diameter is in excess of 0.375 inches, said filter device including a solids discharge outlet connected to the bottom of said filter device and adapted to dump accumulated solids into said tank, said solids discharge outlet being in communication with both said influent and effluent chambers whereby solids collected on either side of said filter medium can be discharged through said solids discharge outlet and into said solids sediment tank; a bank of a plurality of hydrocyclone separators located on said platform, each of said hydrocyclones having a feed inlet and an overflow discharge, and including a feed header in communication with the feed inlet of each hydrocyclone, an outlet header being connected to the overflow discharge of each hydrocyclone, said filter effluent outlet being connected to said feed header, and said outlet header recirculating clarified effluent back to the basin of said cooling tower, each of said hydrocyclones including an underflow discharge means; a sediment solids tank arranged on said platform with said filter device solids discharge outlet and each of said hydrocyclone underflow discharge means in communication with said sediment solids tank; and auger means having an inlet located within said sediment solids tank and an outlet adapted to discharge solids outside said sediment solids tank.
