Abstract: A belt filter press having a wedge zone which can be adjusted during operation of the filter press to prepare a sludge or other material to be deliquified in the most efficient manner for high pressure deliquification also includes a sealing arrangement for sealing the marginal edges of the upper and lower belts, a tapered slide cam assembly on either side of the belts for adjusting the wedge angle in a controlled manner, rack and pinion assemblies associated with hydraulic cylinders on either side of the belts to ensure the uniform movement of the lower belt supports, and the staggered arrangement of upper and lower belt support members where the lower belt support members are concave-like in shape to facilitate the sealing of the marginal edges of the belts, as well as to form a confined pocket which will facilitate the shearing action induced in the material to be deliquified.

Abstract: A side seal assembly adapted for use in a belt-type filtering device. The assembly comprises a hollow elongated holder having at least one open end and a longitudinal slot extending the length thereof. The assembly further includes a rod received within the holder, the rod being of a length approximately equal to the length of the holder and of cross-sectional dimensions greater than the slot of the holder, and a flexible curtain secured to the rod along its length and extending outwardly through the slot in the holder.
