ABSTRACT:
A pressure filtration apparatus including an upper portion with an inflow channel and a discharge channel for the concentrate and a lower portion with a filter support and a discharge channel for the filtrate, the upper and lower portions being releaseably connectable with one another while forming a pressure space. The apparatus contains a distributor plate whose underside is disposed parallel to the upper side of the filter and snugly above the latter while forming an intervening space, and in the center of which is an opening for the concentrate discharge channel. The outer edge of the distributor plate forms a small annular opening which extends all around closely against a basically vertically interior of the pressure space. The top side of the distributor plate has a peripherally raised outer edge which while forming a narrow annular clearance extends to close up against a downwardly pointing horizontal interior wall of the upper portion. The distributor plate has an annular distributor ring surface which grows steadily deeper from the outer edge toward the center of the distributor plate and in the center has a short connecting bushing by way of which the distributor plate is secured to the upper portion and through which the discharge channel for the concentrate runs. The apparatus also includes an inflow channel which opens up in the upper portion in the region of the deepest point of the distributor ring surface above the latter, and at least along a length disposed in front of the opening determining the direction of flow of the emerging inflow current, slopes toward the horizontal at an angle of about 35.degree. to about 55.degree., preferably about 45.degree., and relative to the vertical projection of its axis runs basicaly tangentially to the vertical projection of the distributor ring surface.
In preferred embodiments of the invention, the upper portion, lower portion, the distributor plate, the inflow channel, the inflow channel bushing, the filter support, the filtrate discharge channel, and the filtrate discharge bushing may be made of polytetrafluoroethylene (PTFE). If all are made of PTFE, the inflow, the concentrate and the filtrate will be in contact only with PTFE.
