Description

one

The invention relates to devices for the mechanical purification of water.

A water purification network is known in which the water is cleaned by filter webs submerged perpendicular to the direction of flow.

However, when using a known mesh, all floating contaminants, the approach to it, is pressed over, clogged its cells and even penetrates them. Fish fry are also pressed down to the net and penetrate the cells. With the size of fry close to the size of the cells, they get stuck in them and die. With fry sizes smaller than cell sizes, they pass through it and enter the pumps. In addition, the longitudinal ribs protruding outward between the links of the net grab the fish that approach the net and pick it up in the garbage disposal tray.

The purpose of the invention is to prevent the passage of fry fish and debris through the net, as well as raising fish from water.

This is achieved by the fact that the panels of the proposed grid, submerged in water, are installed parallel to the direction of movement of the jets in the watercourse and are provided with fender visors.

The liquid to be cleaned, the approach to the grid, in order to pass through it, must change its direction of movement from horizontal to vertical and pass through the grids rising to the top.

Suspensions and fish fry that are in the water, while continuing to flow in the stream, encounter the baffles and squeeze in the stream. They cannot penetrate the grid, as the continuously moving panels of grids rise.

The garbage, which may adhere to the grid cloth, is flushed off from the wash pipe at the top of the unit.

FIG. 1 shows the proposed device, vnd above; in fig. 2 is a section along L-A in FIG. one.

The water treatment apparatus consists of grids /, fender visors 2, perforated pipe 3, trough 4, frame 5 and guide sprockets 6.

Purified water fits the rotating grid. Weighted garbage and fish are retained at the diverting peaks 2. Relatively clean water, changing the direction of movement from horizontal to vertical, passes through horizontal nets /, where it is cleaned of residual suspensions.

Due to the fact that the mesh panels all the time

moving up, fish fry cannot be

pressed against it and the fender visor 2 is pressed into the pond. In the upper part of the cloth

washed with water from a perforated pipe 3.

Subject invention

A water purification grid for mechanical purification of water, consisting of one or several panels submerged in water, characterized in that, in order to prevent the passage of fry of fish and debris through the grid, the screens of the grid are installed parallel to the direction of movement of the jets in the watercourse and are fitted with baffles.
