LINEN DRUM DRYER Russian patent published in 2011 - IPC D06F58/00 

FIELD: textile industry.

SUBSTANCE: linen drum dryer contains a closed drying air circuit (designed so that heated drying air is able to pass through a rotary drum), an air condenser for removal of moisture from hot moisture-saturated drying air coming out of the drum; an open cooling air circuit designed so that to enable circulation through the air condenser. The cooling air flow is taken in from the environment for cooling the said condenser and release of the cooling air flow back into the environment. Additionally the dryer contains units catching and gathering fibres for floss removal from the drying air flow. The closed drying air circuit includes an air channel with an inlet hole fluidly coupled with the drum and an outlet hole fluidly coupled with the air condenser and an air flow deviation surface for deviating air passing through the inlet hole and for the air delivery in the direction of the outlet hole. The units catching and gathering fibres contain a water delivery device adapted for water delivery onto the upper part of the air flow deviation surface with formation of a water film or curtain directed downwards along the said surface so that the drying air flow runs over the water curtain and moves along it ensuring the possibility of floss capture and catching by the water curtain; additionally the units contain a drain device designed so that to enable gathering water containing floss on the lower part of the air flow deviation surface.

EFFECT: easy servicing of the dryer.
