Abstract
A solid/liquid separation apparatus in which a downwardly-inclined separator screen is supported across the open front face of a liquid collection chamber. The screen and chamber are mounted in an outer frame having spaced side walls. The screen has separate upper and lower sections and is adjustably mounted on at least one of the side walls at a position intermediate the upper and lower ends of the screen so that it can be moved inwardly and outwardly in a direction transverse to the plane of the screen to adjust the relative vertical angles of screen sections. In one version, the upper and lower screen sections are separate screens and are adjustable via separate adjustment mechanisms.
Claims14
A solid/liquid separation apparatus, comprising:
- an outer support frame having spaced side walls;
- a downwardly-inclined separator screen having an upper end and a lower end and supported on said support frame between said side walls;
- inlet means for directing a solid/liquid mixture to be separated onto the upper end of said separator screen to flow downwardly along the screen towards the lower end of the screen;
- at least one support member extending transversely across the screen at a location intermediate its ends to divide the screen into an upper section inclined at a first vertical angle and a lower section inclined at a second vertical angle on opposite sides of said support member;
- and
- adjustable mounting means for adjustably mounting said screen for movement in a direction transverse to the screen to adjust the first and second vertical angles of the upper and lower screen sections;
- the adjustable mounting means comprising at least one adjustment screw mechanism having a first part secured to one of said side walls and a second part secured to said support member.

A solid/liquid separation apparatus, comprising:
- an outer support frame having spaced side walls;
- a liquid collection chamber between the side walls having an open front face;
- a downwardly-inclined separator screen assembly supported over the open front face of the liquid collection chamber, the assembly having an upper end and a lower end, and the assembly including at least two separate first and second screen sections, each screen section having an upper end and a lower end, and the first and second screen sections being inclined at first and second angles of inclination, respectively;
- hinge means connecting said screen sections together at their adjacent ends;
- an inlet passageway at the upper end of said screen assembly for directing a solid/liquid mixture onto the upper end of the screen assembly;
- first adjustment means for adjusting the first angle of inclination of the first screen section;
- and
- second adjustment means separate from said first adjustment means for adjusting the second angle of inclination of the second screen section independently of the adjustment of the first screen section.
