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.
Claims10
A device for separating liquids and solids from a mixture, said device comprising:
- an endless filter belt;
- means for supplying a mixture to the filter belt;
- a suction box supporting the filter belt, wherein the at least one suction box is located under the filter belt and is configured and arranged to move along the filter belt;
- an underpressure device operable for generating a lower pressure relative to an ambient pressure;
- at least one stationary underpressure box connected to the underpressure device;
- control means for alternately generating the lower pressure and ambient pressure in the suction box;
- and discharge means connected to the suction box, wherein the suction box is bounded on at least one side by a stationary underpressure box and for each underpressure box, the suction box including connecting means co-acting with the underpressure box such that the suction box is reciprocally movable along the stationary underpressure box.
A device for separating liquids and solids from a mixture, said device comprising:
- an endless filter belt;
- means for supplying a mixture to the filter belt;
- suction box supporting the filter belt, wherein the suction box is located under the filter belt and is configure and arranged to move among the filter belt;
- an underpressure device operable for generating a lower pressure relative to an ambient pressure;
- at least one stationary underpressure box connected to the underpressure device;
- control means for alternately generating the lower pressure and ambient pressure in the suction box;
- and discharge means connected to the suction box, wherein the suction box is bounded on at least one side by a stationary underpressure box and for each underpressure box, the suction box includes connecting means co-acting with the underpressure box such that the suction box is movable along the stationary underpressure box and wherein the suction box and the underpressure box have mutually co-acting sealing means.
