DEVICE FOR CLEANING OF WATER BODIES FROM ULIGINOUS DEPOSITIONS AND PROCUREMENT OF SAPROPEL (VERSIONS) Russian patent published in 2009 - IPC E02F5/28 E02F3/92 

FIELD: construction.

SUBSTANCE: group of inventions pertains to the sphere of hydraulic cleaning of ponds from uliginous depositions including procurement of sapropel. Device for cleaning of water bodies from ulignious depositions including procurement of sapropel according to the first version includes dredging equipped with immersible dredging pump having, at least, one sucker connected with the back wall of the dredger made in the shape of horizontally moving scraper scoop. Whereat scoop is equipped with inlet mesh - knife, at least, one vibrator is arranged inside the scoop in the suction area prior to the sucker. According to the second version, the device contains dredging equipped with immersible dredging pump connected by the sucker with the back wall of the dredging device made in the shape of horizontally moving scraper scoop equipped with inlet mesh. Whereat, mixer set on the pump rotation axis is arranged inside the scoop in the suction area, and bending angle of the upper wall of the scoop to the horizon is determined by the width of the cut soil. The distance between the inlet mesh - knife and the back wall of the scoop is selected so to prevent spontaneous suction of free water.

EFFECT: ensured fluidity of the pulp with natural humidity, sufficient for its stable (uniform) suction by dredging pump without dilution with outside water.
