FIELD: hydraulic excavation, condensing-clarifying apparatuses. SUBSTANCE: the apparatus is made in the form of a horizontally positioned parallelepiped and can be placed in a horizontal working with vertical dams; it has at least one receiving cylinder intended to receive the supplied hydraulic fluid and installed vertically in the center of the representative square of the filter. The horizontal suction device with soil intake windows intended for removal of the filter bed and provision of a stable process of filtering is positioned above the water-distributing manifold at the height of the filter bed. The horizontal suction device is located around the edges of the apparatus at a distance of 0.3 to 0.4 m from the wall, at the corners of the filter representative square it is furnished with soil intake windows and connected to the water intake device through a calibrated branch pipe. Such a design provides for restoration of the filter bed uniformly over the entire filtering area and removal of the smallest particles of solid incorporated in the filter. The offered apparatus provided for condensing the hydraulic fluid in underground conditions or on the surface with volumetric ratio of solid in it up to 50%, clarification of water with concentration of water in it up to 1 g/l without any use of chemical reagents with unit loads up to 40 cu.m/h per sq.m. EFFECT: enhanced efficiency. |
