    Abstract: A comminutor for comminuting solid materials carried by flowing fluids, such as industrial wastes or sewage, in which cutter elements carried by a plurality of rotating rings forming a cone shaped rotor co-act with stationary cutter elements supported alongside the rotor, and a method of comminuting. The stationary cutter elements are reversable so that upon repositioning, new stationary cutting edges are presented to the cutter elements carried by the rotating rings. A plurality of stationary cutter elements are formed on a single structure, each stationary cutter element forming a cutting station. The cutting action is further increased by providing co-acting cutting edges in planes perpendicular as well as parallel to the rotor axis at each cutting station.

    Abstract: A filter apparatus comprises a filter screen for filtering liquid carrying solids to remove at least some of the solids from the liquid. A nozzle is arranged adjacent the filter screen for removing solids deposited on the filter screen during a filtering operation, a variable speed drive causes relative movement between the filter screen and the nozzle such that deposited solids are removed from successive portions of said filter screen, and a control unit controls the speed of the relative movement in dependence upon the degree of blockage of the filter screen by the solids deposited on the filter screen. Throttling the discharge of the filtered liquid causes liquid to flow from the side of the filter screen remote from the nozzle back through the screen into the nozzle which is provided with an inlet having an adjustable cross-sectional area for varying the flow therethrough. A cleaning system arranged to direct clean liquid through the filter screen into the nozzle is provided for cleaning the screen should the screen become completely blocked.

    Abstract: In a spin filter, a hollow mandrel is rotatable axially in a filter tank and has mounted thereon a multiple of concentric porous hollow filter discs which open centrally into said mandrel. Liquid, containing impurities, and in some instances mixed with a purifying agent such as dietamaceous earth is delivered into the tank, the impurities being removed therefrom as the liquid passes through the filter discs into the mandrel from one end of which the filtrate is recovered. It is customary to depend on a periodical reverse flow of filtrate through the filter while spinning the mandrel, for cleaning the deposit of impurities from the filter discs. Following this operation, the deposits thus loosened into the liquid in the tank are flushed from the tank to waste. The present invention quickens and enhances the cleansing of the filter discs by providing an inexpensive series of brushes disposed between adjacent pairs of filter discs by which the latter are scrubbed during the filter rotating and back washing operation.

    Abstract: A rotary drum filter having a filter aid layer on its filter surface is provided with an adjustable scraper at the line of discharge of the filter cake and with an adjustable stripper adjacent the line of wet filter cake formation as the filter cake emerges from the slurry tank. The scraper is automatically advanced toward the drum to progressively remove the filter cake with portions of the filter aid layer as the drum rotates and the stripper also is either manually or automatically advanced toward the drum to maintain a substantially constant thickness of filter cake on the layer of filter aid as the thickness of that layer progressively decreases.

    Abstract: Liquid entering at (9), Fig. 1 (not shown), is filtered inwards through strainer elements (13) on a vertical drum (11) rotated by a motor (53) mounted above the housing (2), or by hand at (51a). Most of the filtrate flows downwards through an opening in a ring (8) forming part of a fixed partition structure (7); the open lower end of the drum has close contact with the inside of the ring (8); filtrate is discharged at (10). The remaining filtrate flows outwards through those strainer elements which at any instant are opposite a slot (16) in a fixed vertical shoe (14) making close contact with drum (11); such filtrate, with residues, is discharged at (17). Two diametrically-opposite shoes instead of one may be provided, Fig. 4 (not shown). The clearance between drum (11) and ring (8) may be adjusted by raising or lowering the drum shaft (21) in a combined thrust and radial bearing (32 to 34), this being done by rotating a nut (40) threaded on shaft (21) above the bearing, and then bending up a portion of a locking ring (41) (beneath the nut) to engage a peripheral slot in the nut 40. (The locking ring may only slide on shaft (21)). When this has been done, further vertical movement of shaft (21) may be prevented by performing the same operations on an identical (but inverted) bearing structure at the top of the shaft. The drum may be eccentrically mounted with respect to the housing, Fig. 4 (not shown).
