Description

The invention relates to screen filters, namely, conical water purification nets (filters) installed directly in pipelines, and can be used to clean liquids in various areas of the national economy, including land reclamation, food and chemical industry, atomic energy, and so on. d.

 The purpose of the invention is to ensure the operability of the filter at high concentrations of contaminants with different specific gravity and different patterns of their distribution on the filter element, by achieving different regenerating ability of the washing device along its generator.

FIG. 1 shows a filter; general view, section I in FIG. 2 - washing device with a local incision; FIG. 3 is a section A-A in FIG. one; FIG. 4 is a section BB in FIG. one; FIG. 5 shows a section B-B in FIG. one.

The fluid purification filter contains a housing 1, a filtering element in the form of a fixed mesh cone 2j, a washing device 3 with a cowling 4j located inside the mesh cone 2 and made in the form of a tetragonal pyramid rotatably mounted, each facet of which has a double curvature surfaces 5, between which are formed the earth-removing gaps 6. | the actuator 7 for rotating an external device Sj into the groundwater extraction pipe, originating from the small base of the mesh cone 2,

The filter works as follows.

The contaminated water, moving in the housing 15, gets onto the fixed net cone 2, and, filtering through it, leaves 2 contaminant particles on the inner surface of the net cone 2. Inside the mesh cone 2, a hollow industrial device 3 is rotated by means of a turbine or other drive. Since the pressure in the housing 1 is greater than the pressure inside the washer 3, the liquid directly near the mesh cone 2 is sucked inside the jet device 3, the particles deposited on mesh cone 2. Outside the industrial pollution control device 3 (slurry) is discharged by means of a drain pipe 8, due to the pressure drop in pipeline 8 and in the atmosphere.
