Abstract
An improved sludge classifying press for isolating biologically-digestible materials from sludge. The press comprises a tubular shell containing a cylindrical separation screen and a tapered auger driven within the separation screen by a motor and transmission. The SCP assists in fracturing the protective casings of resistant seeds and passing the resulting comminuted solid materials in a liquid stream of BOD materials. The separation screen may be repositioned with respect to the tubular shell by rotation to distribute wear by grit impingement that occurs during use preponderantly at the bottom of the screen, thereby extending the working life of the screen.
Claims6
A sludge classifying press, comprising:
- a tubular shell having at least one fixed end plate having an opening;
- and a cylindrical screen disposed within said shell and removably attached to said at least one fixed end plate and surrounding said opening, wherein said tubular shell, said at least one fixed end plate, and said cylindrical screen are non-rotational during a period of operation of said sludge classifying press, and wherein a rotational position of said cylindrical screen with respect to said tubular shell is adjustable during a period of non-operation of said sludge classifying press.
