Each of the plate units includes a main body, a first combing portion, a second combing portion, a first flange and a second flange. The main body has a first side surface, a second side surface and a through hole. The first side surface is opposite to the second side surface, and the through hole extends from the first side surface to the second side surface. The first combing portion and the second combing portion are disposed on the first side surface and the second side surface respectively. The first flange and the second flange respectively protrude from the first side surface and the second side surface and respectively. The first combing portion of one of the plate units is combined with the second combing portion of another one of the plate units, so that a sieving structure.

    摘要： The present invention provides a multi plate screw press sludge dewatering machine and a helical shaft thereof. The multi plate screw press sludge dewatering machine includes fixed rings, movable rings, the helical shaft, a sludge inlet tank and a sludge discharging tank; the helical shaft adopts a variable diameter variable pitch helical shaft, a lead angle arrangement sequence of a helical blade of the whole helical shaft is gradual reduction from the sludge discharging tank to the sludge inlet tank, and the lead angle arrangement sequence is gradually reduced from 16°-22° to 6°-14°; a pitch of the helical shaft is gradually increased along a direction from the sludge inlet tank to the sludge discharging tank; a diameter of a shaft body of the helical shaft is gradually increased along with a direction of the sludge discharging tank from a ⅓ position of a shaft length; and blockage prevention plates are arranged on two sides of the bottom of the helical blade. The helical shaft in the present invention is specially designed, so that the pitch is more reasonable, a helical angle is gentler, frictional resistance when sludge passes through the helical shaft may be effectively reduced, and phenomena of shaft blockage and shaft sticking of the sludge may be reduced.

    摘要： The invention relates to a filter element comprising one or more fluid-pervious layers of a fluid-pervious sheet material having first and second surfaces in a substantially parallel arrangement, a fluid-impervious layer arranged in fluid tight contact with at least one of said first and second surfaces of said layer(s) of fluid-pervious sheet material to substantially fully cover the first and/or second surfaces thereof, one or more first and second edge portions, said first and second edge portions being arranged at a predefined distance and separated from one another by a predefined area of the fluid-pervious sheet material, a fluid flow path limited to and extending essentially parallel to the first and second surfaces from the first edge portion(s) to the second edge portion(s) within each of said layers of fluid-pervious sheet material, said first and second edge portions providing a fluid intake and a fluid drainage at the upstream and downstream ends of said fluid flow path, respectively. The invention further relates to filter modules comprising one or more of said filter elements.

    摘要： A screen intake system has a body with an open end and a chamber. A flat screen is disposed at the open end of the body. To keep the screen clear of debris, an airburst system has pipes disposed in the chamber. The pipes dispose parallel to one another adjacent the flat screen, and each of the pipes has orifices in a side facing the flat screen. Directors are disposed along the backs of the pipes in a lattice, and each of the directors has a channel in which the pipe disposes. Compressed air released by valves from a tank dispersed from the pipe's orifices. Each of the directors directs the resulting water/airburst from the orifices toward the adjacent flat screen to clear it of debris.

    摘要： The present invention relates to water filters utilizing disc filter elements and in particular, to such a filtering apparatus having self-cleaning capabilities by utilizing automated back-flushing to clean the filtering elements where the self-cleaning process is enhanced by introducing a secondary flowing fluid, preferably atmospheric air, into the back-flushing stream. The filter apparatus is further enhanced with a disc filter spine having a plurality of spray nozzles arranged on the spine channels that may be adapted to produce a cleaning flowing fluid jet stream at a variety of angles facilitating cleaning, separation and spinning of the disc filtering elements. The filter apparatus may further enhance the cleaning process by introducing a flushing apparatus adapted to facilitate removal of effluent from the filter.
