Wash press having improved rotor structure and housing for removing the same

A wash press configured to separate liquids and solids from a waste stream comprising:

• a tank having a semi-cylindrical shape, the tank having an inlet at a top of the tank, and a screen disposed in a portion of a bottom of the tank to permit liquid to pass therethrough, an outlet for permitting solid materials to pass therethrough, and a drive end portion;
• a rotor having a plurality of helical flights interconnected by paddle members;
• and
• a drive supported by at the drive end portion of the tank and configured to rotate the rotor and connected to the rotor via a shaft extending through the drive end portion of the tank,
• wherein the rotor is configured to transport solid and liquid materials along the tank from the inlet to the outlet in a forward transport direction away from the drive end portion, and to disturb and compress the solids in the tank to separate the liquid fro the solid materials, and
• wherein a removable cover is disposed on a top part of the tank and extends to the drive end portion of the tank, the cover having a drive end flange portion configured to form an upper part of the drive end portion of the tank, the drive end flange portion configured to create an opening at the drive end portion when the cover is removed to enable the rotor to be moved vertically upward above the tank,
• wherein the drive end portion of the tank is open at an upper portion to permit the rotor or the rotor shaft to move vertically upward above the tank, the open part configured to be closed by the drive end flange portion of the cover.

A wash press configured to separate liquids and solids from a waste stream comprising:

• a tank having a semi-cylindrical shape, the tank having an inlet at a top of the tank for receiving waste materials, a screen disposed in a portion of a bottom of the tank to permit liquid to pass therethrough, and an outlet for permitting solid materials to pass therethrough;
• a rotor means for transporting and agitating the waste materials;
• and
• a drive configured to rotate the rotor,
• wherein the rotor means is configured to transport solid and liquid materials along the tank from the inlet to the outlet in a forward transport direction, and to compress and disturb the solids in the tank to separate the liquid from the solid materials.
