    Abstract: In a system for separating solids from a liquid in a slurry, a filter apparatus is cleaned by a jet and a removal device. The filter is generally flat and has an inflow side on which the solids are deposited and an outflow side supported by a grid. The grid subdivides the outflow side into a plurality of separate injection chambers and defines a plurality of separate small regions of the filter. The jet directs a stream of liquid through one of the injection chambers and against one of the small regions of the filter defined by the injection chamber. A cover plate is provided on the jet for engaging the grid to close one injection chamber opposite the filter. The removal device is located on the inflow side of the filter and is aligned with the jet to receive solids dislodged from the filter. The jet and removal device move simultaneously and in alignment to close selectively and to direct a stream of liquid through each of the injection chambers.

    Abstract: The sifting device consists of a chamber with an opening for feeding pulp to be sifted; a cylinder plate installed in the chamber so that it can be rotated around its axis; at least one fixed sieve cleaner with an outlet pipe open toward the sieve surface for removing reject pulp, a lower pressure prevailing in the outlet pipe than on the sieve surface; a detachment organ for reject installed in connection with the outlet pipe; and a blocking piece on the side opposite to the open part of the outlet pipe.

    Abstract: 1,202,314. Simultaneously filtering and backflushing. CARRIER CORP. 28 Feb., 1968 [23 Aug., 1967], No. 9712/68. Heading B1D. Fluid flows into a chamber 63, through an opening in a plate 59 (arrow A), through a basket strainer 73, and into an outlet chamber 65. Partition 69 prevents fluid entering the right-hand half of the basket. After clogging occurs, valve plate 61 is rotated by a handle secured to a shaft 79, thus allowing flow through plate 59 into the right-hand half of the basket 73 but preventing flow into the lefthand half. The left-hand half is backwashed by opening the left-hand valve 77.

    Abstract: A backflushing filter having an inlet, an outlet, and a drain; a filter that divides a housing into an inlet chamber that is connected to the inlet and an outlet chamber that is connected to the outlet; a backflushing device having a suction element arranged so that it is able to rotate around the filter on the inlet side of the housing with at least one suction opening that is oriented in the suction direction toward the filter for filter-cleaning purposes; a backflushing duct connected to a suction opening and an outlet opening; and a rotating device which drives the rotational movement of the suction element around the filter when a pressure drop occurs in the backflushing duct; wherein when the pressure drop in the back flushing duct occurs, the rotating device drives the rotational movement of the suction element by the suction direction of the suction opening that is inclined relative to the radial direction of the suction element.
