Abstract: A filtering device for separating liquid and solid material from a mixture consists of an endless filter belt. Filtrate is separated off by means of the pressure difference above and below the filter belt. The device is placed in a high pressure space in order to keep liquid substances which at ambient temperature and atmospheric pressure would become gaseous. The applied pressures can rise to roughly 20 bar.

Abstract: A separating device comprises an endless carrier belt which supports a filter belt. Suction boxes for drawing off filtrate are placed on the side of the carrier belt. The carrier belt protrudes laterally into the continuous slot of the vacuum box. In a large separating installation with long carrier belts and filter belts lateral displacements of the carrier belt occur during operation, whereby sealing becomes a problem. These problems are resolved according to the invention in that the suction box has a sealing member connecting onto the side edge of the carrier belt and this sealing member is displaceable laterally.

Abstract: In a device for filtering, washing and drying a solid material-liquid mixture, using a liquid permeable filter cloth the mixture is first subjected to a pressure difference above and below the filter cloth, whereafter liquid is supplied to the mixture. The mixture present above the filter cloth is then dried according to the invention using radiation sources, the radiation from which has differing, preferably increasing, wavelengths in the processing direction. The wavelength lies in the infrared range. The applied wavelength is chosen subject to the product for filtering.

Abstract: The invention relates to a device for separating liquids and solids. An endless filter belt is used, beneath which a suction box is placed which can generate underpressure relative to the ambient pressure. The suction box is bounded on at least one of the sides by a stationary underpressure box, wherein the suction box is provided with a connecting element co-acting with the underpressure box. This enables embodying of the connection between the suction box and this underpressure box without for example rubber connecting hoses. This is important because rubber material cannot for instance withstand high temperatures.

Abstract: The present invention provides an apparatus for separating into solid material and liquid a mixture thereof. The apparatus includes a movable filtering element for filtering the mixture, a feed device for supplying the mixture onto the filtering element, a suction device for drawing off liquid from the mixture through the filtering element and a measuring device for measuring the area or areas on the filtering element where the liquid is predominantly to be found.

Abstract: Continuously operating filtering devices are voluminous when accommodated in a casing. The casing serves to maintain a determined pressure around the filter, for instance by use of released gases. It is the ojective of the present invention to keep the volume as small as possible. This is achieved by using plastic material for the carrier belt. Up to the present, rubber carrier belts have been used. These however impose limitations on the diameter of the guide rollers. A limitation of the roller diameter to 25% in comparison to rubber carrier belts is possible with the use of plastic. In addition, plastic has a better resistance to aggressive substances.

Abstract: A device for separating liquid and solid material from a mixture consists of an endless filter belt, beneath which is arranged a suction box connected to a vacuum device. The suction box supports the filter belt. The filter belt moves continuously while the suction box performs a reciprocating movement in the direction of the filter belt. In order to make possible the reciprocating movement of the suction box the connection of the suction box to the stationary vacuum device is embodied as a telescopic connection consisting of a stationary part connected to the vacuum device and a part connected to the suction box and slidably movable in the stationary part.

Abstract: The invention relates to a method and device for removing liquid from a mixture of solids and liquids, whereby the mixture is deposited on the upper part of an endless drivable filter belt and whereby during operation the upper part of the filter belt is led over at least one casing in which a sub-atmospheric pressure is generated. After having passed the casing(s) in which a sub-atmospheric pressure is generated, the mixture is carried through a least one microwave oven by means of the filter belt.
