摘要:
Solids are removed from a manure slurry using a sloped screen separator (300) having small openings. Spray heads (356) direct water onto the sloped screen (344). Additionally, the separator (300) controls the air flow through the sloped screen (344).
摘要:
The invention relates to a sieve (1) in which the passage cross-section of the sieve openings (4) can vary automatically in accordance with an inherent variable of the medium passing through the sieve (1). When using one such sieve (1) in a technical process, the sieve (1) is automatically cleaned during the process by the parts deposited thereon.
摘要:
The invention relates to a filter (1), which is characterised in that the size of the cross-section of the filter openings can be modified in conjunction with an inherent variable of the medium that traverses the filter. By using a filter (1) of this type in a technical process, deposits on said filter (1) are automatically cleaned during the course of the process.

A filtering apparatus of T-shaped configuration includes a vertically extending filter element receiving tube and a horizontally extending outlet conduit portion. A removable tubular filtering element having a flexible seal surrounding the outer surface of the filter element at a lower end is engagable with an inner surface of the filter element receiving tube. A stationary filter element is disposed at a juncture of the outlet conduit with a central opening in the vertically extending filter element receiving tube wherein the flexible seal of the filter engages with and cleans the particulates from the stationary filter element upon insertion and removal of the tubular filtering element from the filter element receiving portion.
摘要:
A filtering system for filtering effluent in a septic tank including an outer secondary filter secured within a pipe fitting, wherein the outer secondary filter includes a central opening passing therethrough; an inner primary filter, wherein the inner primary filter is slidingly engaged within the central opening in the outer secondary filter; and a filtering connection element, secured between the outer secondary filter and an inner surface of the pipe fitting, wherein the filtering connection element filters effluent passing upward through the filter pipe fitting and wherein upon removal of the inner primary filter, the outer secondary filter filters the effluent entering the pipe fitting before discharge. Either or both of the outer secondary filter or the inner primary filter may be formed with a biocide to retard the growth of biological material on their surfaces.
摘要:
A microstructured filter for a fluid, the filter having an inlet for unfiltered fluid and an outlet for filtered fluid, the filter comprising: a plurality of projections (7) which are arranged in at least two rows (3) in mutually juxtaposed relationship and which project out of a base plate (1) and which are an integral component of the base plate, a plurality of passages (8) between the projections (7), and a cover plate which is securable to the base plate to cover the projections (7) and the passages (8), wherein the passages form a plurality of through paths from the inlet to the outlet, said inlet comprises an elongate inlet slot (5) for the unfiltered fluid, which extends over approximately the entire filter width and which is approximately as high as the projections (7) projecting out of the base plate, on the inlet side of the filter, and said outlet comprises an elongate outlet slot for the filtered fluid, which extends over approximately the entire filter width and which is approximately as high as the projections (7) projecting out of the base plate, on the outlet side of the filter. The filter according to the invention remains operational, even if a part of the filter area is obstructed. The filter is used for example in an atomiser with which an aerosol is produced from a fluid which contains a medicament.
摘要:
A device is disclosed for removing solids from liquid flowing along a channel (3), in particular in sewage treatment facilities. It is provided with a separator surface (8), in particular a vertical surface which is partially submerged in the liquid and takes the form of a cylindrical jacket, is composed of stationary at least approximately semicircular bars (10) with a clearing arm (12) which is driven to rotate about the axis (2) of the separator surface (8) and has clearing elements (15) which poke through between the bars (10) from the inside outwards, and with a conveyer device (17) adjoining the separator surface (8) and leading to a discharge point outside the liquid for the solids. The conveyer device has a tubular housing (22) with a recipient aperture (23) for the solids and a driven conveyer screw. The convex side of the stationary and at least approximately semicircular bars (10) which form the separator surface (8) face the flow direction (5) of the liquid entering the gutter (3), ensuring that the solids are deposited on the outer stationary separator surface (8). The clearing elements (15) on the driven clearing arm (12) protrude between the bars (10) against the direction (29) of passage of the liquid. The section of the cylindrical jacket (9) not taken in by the approximately semicircular bars (10) is open. The conveyer device (17) is set into the channel (3) obliquely.
