biological structures from algae. SUMMARY OF THE INVENTION: in front of the grating 6, in guides 8, a frame 1 is installed with track rollers 2, a drive drum 4 and a comb 3. On the surface of the drum 4, elastic cleaning elements 5 are made along a helical line and are made rectilinear with a length greater than the length of the teeth of the comb 3, and placed opposite the gaps between the teeth of the comb 3. The frame 1 is moved by a crane along the guides 8. The elastic elements 5 on the rotary drum 4 capture the algae and move them through the comb 3. Algae crushed on the comb 3 carried by a stream of water between the rods of the grid 6.3 sludge.

Phage /

The invention relates to hydraulic engineering, and in particular, to devices for cleaning algae from the intake channels of pump stations of shipping channels and other hydraulic structures.

The purpose of the invention is to increase operating efficiency under conditions of algae in water.

Fig. 1 is a schematic view of an apparatus for cleaning algae trash screens, general view; in FIG. 2 is a section AA in FIG. 1; in FIG. 3 is a view B of the slit comb of FIG. 2.

The device comprises a frame 1 with road rollers 2, a rigid slit-like comb 3 and a drum 4 in the form of a shaft, on the surface of which rectilinear elastic cleaning elements 5 are fixed along the helix, passing between the rods of the trash grating 6 and through the slit-like comb 3, mounted teeth mi down over the drum 4 parallel to the axis. The elastic cleaning elements 5 are made with a length greater than the length of the teeth of the comb 3 and are placed on the drum 4 opposite the gaps between the teeth of the comb 3. The hermetically sealed drive 7 rotates the drum 4. The rollers 2 move along the guides 8 installed in front of the containment bars 6.

A device for cleaning the trash grate from algae works as follows.

Using a lifting crane, the frame 1 is lowered on the rollers 2 along the guides 8 along the rods of the trash bin 6 with the drive 7 turned on, the rotary drum 4. The elastic cleaning elements 5, the passage between the rods of the grill 6, seize the algae and move them through the slit comb 3. The crushed algae are carried away by a stream of water through the rods of the grate 6. When the elastic elements 5 come into contact with the slit comb 3, self-cleaning occurs. When elastic elements 5 get on the rods of the trash holding grid 6, ibayuts that allows the drum 4 to rotate freely.
