CONVEYOR PRESS FOR BIRD DROPPINGS DEHYDRATION Russian patent published in 2020 - IPC C05F3/06 

FIELD: agriculture.

SUBSTANCE: invention relates to the agriculture. Conveyor press for bird droppings dehydration comprises filtering conveyor and located above it, at acute angle, pressure transporter, loading device and device for removal of solid fraction, drive and tensioning drums, control panel. Equipped with additional hopper for coarse-grained plastic material with particle size of 3…10 mm with dispenser arranged in front of bird droppings bunker with dosing unit, side plates tightly closing sides between clamping and filtering conveyors, support perforated plate for working branch of filtering conveyor, support solid plate for working branch of pressure transporter. Side plates, support perforated plate and support solid plate are made of material with low friction coefficient, within 0.02…0.05. There is a unit for cleaning a perforated filter belt of a filtering conveyor in the form of a chamber with a roller, which provides bending of the tape, and with supply of pulses of compressed air into the chamber. Sharp ribs are fixed perpendicular to outer surfaces of filtering and pressure conveyor belts.

EFFECT: technical result is to reduce the amount of poultry manure solid fraction penetration into liquid, reducing 3–5 times the amount of auxiliary materials for performing a dehydration process, avoiding water consumption for regeneration of the filter tape and subsequent cleaning thereof, as well as separation of protein nitrogen from non-protein nitrogen compounds for more useful use.
