Title: Vertical decomposing device for separating mercury and alkali metal hydroxides
IPC: C25B1/42
Filed: 1967-09-20
Abstract: Alkali-metal hydroxide is produced during the recovery of mercury from alkali-metal amalgam using a device which comprises a decomposition chamber which is separated from a washing chamber by means 16, such as a sieve, which is permeable to mercury and retains a solid catalyst 17, such as graphite, in the decomposition chamber, the washing chamber having at least two intermediate plates which are in the form of upright cones, 3 and 5, alternating with suspended inverted truncated cones 2 and 4, the distance apart of the plates being adjustable.

Title: Continuous filtering-settling centrifuge
IPC: B04B5/02
Filed: 1979-01-25
Abstract: The subject of the invention is a continuous filtering-settling centrifuge designed for separating continuously mixtures containing solid and liquid bodies. In the centrifuge several filtering or settling baskets are applied, situated beyond the main axis of spinning, and rotating around their own axes at an angular velocity different from the angular velocity of the centrifuge. In the particular filtering or settling baskets there is applied a system of feeding the mixture to be centrifuged, constituting a separated feeding zone, and a discharge system constituting a separate discharge zone with a chute receiver or a worm receiver. Besides, in the particular baskets there are separated zones of centrifuging, washing the solid part with a liquid, steaming of the solid part, separating of the washing agent or steaming agent, drying of the solid part, and washing of filtering screens with appropriate technical means in the particular zones. In the baskets finned partitions are applied. The finned partitions prevent a displacement of the mixture along the circumferences of the baskets, thus preventing damaging of the centrifuged solid part and the filtering screens in case of the filtering centrifuge, and also enable to drain off liquid from the basket in case of the settling centrifuge.
