A tumbler may be used as defluidizer, dryer, coater, classifier, or dynamic filter. The tumbler includes a housing for rotatably supporting a removable screened drum on a plurality of rollers. The drum receives a solid/fluid slurry through an inlet chute. As the slurry travels through the drum, fluid exits the drum through a plurality of apertures in screens attached to the sides of the drum, while the solids continue along the drum's length until they reach one or more openings and exit the drum into an outlet chute. The outlet chute includes ridges that wrap around rings extending from the openings of the drum to prevent solids from escaping the outlet chute. To further dry the solids before they exit the drum, an air tube disposed within the drum is configured to direct air through the screens to an air blower intake positioned outside of the drum.

The invention relates to a rotary pressure filter module (100) which comprises a rotary pressure filter (200) having a plurality of supply lines (302, 318, 330) for supplying a suspension, washing medium, drying medium, and optionally other operating media to be filtered and having a plurality of discharge lines (314, 326, 348) for discharging mother filtrate, washing filtrate, and filter cakes, different sensor devices (306/308/310, 322/324, 334/336, 316, 328, 349) being assigned to the supply lines and the discharge lines, and adjusting devices also being assigned to the supply lines, the rotary pressure filter module (100) additionally comprising a control device (400) which is connected to the sensor devices and the adjusting devices. According to the invention, the decentralised control device (400) assigned to the rotary pressure filter (200) is arranged on the rotary pressure filter (200) or in its immediate vicinity and has a signal input via which it can be brought into data exchange connection with a central control device, which does not belong to the rotary pressure filter module (100), of a higher-level production system.

A solid-liquid separation device of the present invention is a solid-liquid separation device, in which a filtration belt (1), a seal belt (8), and a squeezing belt (15) are wound around an outer circumference of a separation roll (7) rotated in a circumferential direction and are able to run along a rotational direction of the separation roll (7), an object (P) to be processed supplied between the filtration belt (1) and the seal belt (8) is sandwiched between the filtration belt (1) and the seal belt (8) on the outer circumference of the separation roll (7) and squeezed by the squeezing belt (15), and the object (P) to be processed is dehydrated by being ventilated by ejecting a ventilation gas toward a radially outer side of the separation roll (7) via a ventilation gas chamber (10) formed in an inner circumferential portion of the separation roll (7), in which the seal belt (8) is a woven fabric of multifilament or a woven fabric obtained by combination of multifilament and monofilament and is a thinner than the squeezing belt (15).

The outlet chute includes ridges that wrap around rings extending from the openings of the drum to prevent solids from escaping the outlet chute. To further dry the solids before they exit the drum, an air tube at least partially disposed within the drum is configured to introduce a flow of air into the drum.

A process for the separation of the components of a solid/liquid mixture. The process Includes the use of a rotary pressure filter apparatus having improved capacity.

A method for continuously filtering a liquid slurry, such as an oil sand and solvent slurry, in a horizontal pan filtering device is provided. In particular, separate filtrate receivers are built under the wet and the dry sectors of a pan filter to take advantage of the liquid seal at the wet sectors so that the solids in the slurry can be compressed by having a higher vacuum under the wet sectors.
