SAPROPEL PRODUCTION COMPLEX Russian patent published in 2007 - IPC E02F3/88 

FIELD: mining, particularly equipment to produce high-viscous sapropel from drainless water body.

SUBSTANCE: sapropel production complex comprises floatation device and sapropel entrainment and transportation means made as scraper conveyer with two horizontal and inclined sections. Conveyer end is located in productive sapropel mass and is suspended from floats by means of flexible members. Conveyer head is supported by bank and adapted to unload sapropel from conveyer into bunker. Horizontal sections of upper load-bearing conveyer branch are arranged in opened guiding chute section. Lower idle branch thereof is located in sealed guiding chute section. Load-bearing branch of inclined conveyer section is in sealed guiding chute. Lower end of sealed guiding chute is submersed in productive sapropel mass, upper one is located over water body surface. The guiding chute is made as pipe cuts connected with each other and provided with panels diametrically fixed inside the pipes. The panels separate load-bearing and idle branches. Pipe cuts in scraper conveyer end are provided with slots made in pipe cut tops. Pipe cuts are connected with each other by means of round-link members installed in loops. The loops are connected from above to adjacent pipe cuts. Each joint is provided with elastic yoke enclosing the joint. Free yoke ends are connected with each other by tightening screw from above. Adjacent pipe cuts are spaced apart. End part of scraper conveyer end has anchoring device.

EFFECT: simplified structure, possibility of scraper conveyer part to be submersed in sapropel mass bending in horizontal and vertical planes during sapropel excavation, improved complex maneuverability and sapropel extraction completeness.
