摘要:
The vacuum filtration device has a disposable filter funnel and a disposable filtrate receptacle. The funnel and receptacle are used with a reusable base that is connected to a vacuum source. When the receptacle and funnel are mounted on the base the vacuum is applied through a connecting passage to the receptacle to draw the filtrate from the funnel into the receptacle.

A vacuum filtration apparatus is provided with on more vacuum chambers fixedly secured at predetermined positions. The interior of the vacuum chamber alternat between a partial vacuum and atmospheric pressure. An endless filter belt has a horizontal section disposed a the vacuum chamber. A slurry is fed from one or more slurry feeders onto the horizontal section of the endle filter belt so as to create a cake of solid particles. Water is fed from one or more water feeders onto the ca to wash the solid particles on the endless filter belt. The endless filter belt intermittently advances by a predetermined length. When the endless filter belt is stopped, the vacuum chamber is under a vacuum so as to d the liquid constituent from the slurry, thereby obtainin purified cake of the solid particles. The vacuum filtration apparatus is provided with a coupling bar at which the slurry feeder and the water feeder is attached. The coupling bar can reciprocate along the endless filte belt by the length of the intermittent advancement of the endless belt. Preferably, the coupling bar is connected a belt advancing device so that the advancement of the endless filter belt causes movement of the slurry feeder and the water feeder in the direction which is the revers of the direction of advancement of the endless filter belt

A disposable filtration unit with recoverable filter and method of manufacturing the same, the unit (10) comprising: a) a receptacle (12) for receiving filtrate; b) a support plate (16) fixed to the receptacle 12 and having at least one opening therethrough; c) a filter membrane (18) on the support plate (16); d) an open-ended shell (14) for receiving a liquid to be filtered, the shell (14) having a lower end portion extending into the receptacle (12) and against the support plate (16) and filter sheet (18); e) seal means between the shell (14) and support plate (16); and f) breakaway means (30) connecting the shell (14) to the receptacle (12) at spaced intervals about the periphery thereof, and providing weakened rupture points which permit separation of the shell (14) and receptacle (12) for recovery of the filter membrane (18). The breakaway means can comprise vertical ribs (30) which extend between the shell (14) and receptacle (12) and which provide the sole attachment of the shell to the receptacle. These ribs (30) can be formed integrally with a necked portion (24) of the shell (14).

摘要:
A filter system for filtering solids includes a filtration tank for receiving a slurry containing the solids to be filtered. A filter assembly including a plurality of filter cells each having a filter medium at an exterior and a cavity at an interior is lowered into the filtration tank using a transport device carrying the filter assembly. A vacuum transfer system is connected to the filter assembly so as to transfer a vacuum to an interior of the filter cells. The vacuum transfer system is operable to perform the filtering and to retain the filtered solids while the transport device moves the filter assembly relative to the filtration tank.
