COMPLEX FOR RECOVERING AND REPROCESSING OF SAPROPEL Russian patent published in 2004 - IPC

FIELD: mining industry and agriculture, in particular, recovery and reprocessing of sapropel for producing of fertilizer.

SUBSTANCE: complex has floating vehicle with drive, mud pump, suction branch pipe, pressure pipeline, and sapropel reprocessing apparatus. Floating vehicle drive is made in the form of two-drum winch mounted on basin bank and kinematically coupled to floating vehicle by two cables fixed with their ends on opposite sides of floating vehicle. One of cables is positioned for running around deflecting pulley, which is fixed on side opposed to winch. Mud pump is located in hermetically sealed capsule secured to lower end of hollow vertical bar mounted for displacement in floating vehicle guides and kinematically connected with drive, which is made in the form of rack attached to bar and toothed gear engageable therewith for transmitting torque from reducer drive to toothed gear, said reducer drive being equipped with brake. Pressure pipeline is made in the form of rigid portion located inside hollow bar and flexible hose with floats, said rigid portion and hose being connected with one another. Flexible hose is disposed on basin water surface and communicated with sump on basin bank. Length of fused portion of hose exceeds width of producing zone of basin. Sapropel reprocessing complex has successively arranged accumulating hopper with screw feeder and slotted dosing device, sapropel hygroscopic dehydration devices and mixer mounted for feeding organic or mineral filler therein, hopper with screw-type unloader, and fertilizer store.

EFFECT: simplified and low-cost process for recovery and reprocessing of sapropel and provision for more complete and ecologically clean process for working out of sapropel deposit.
