DEVICE FOR COMPRESSION WASH OUT OF LABORATORY SAMPLE OF WOOL Russian patent published in 2008 - IPC D01B3/04 D01B3/00 

FIELD: mechanical engineering.

SUBSTANCE: device for compression wash out of laboratory sample of wool has bath for detergent, meshed cassette for wool t be treated provided with false bottom and compression unit for pressing mass of wool; cassette is disposed inside bath. Compression unit is provided with drive to bring it into reciprocal motion. Device is provided with perforated collector for compressed air, which collector is mounted in bath under false bottom of cassette where wool to be treated is pressed in detergent solution due to spring-loaded compression unit for provision of pressure within 10-120 kPa. Compression unit, made in form of movable piston with sliding clutch and its lock are mounted onto rod. Clutch and lock are connected with return spring and rest. Compression cinematically communicates with cock onto air duct, which duct provides supply of compressed air into cassette in position when piston is put up only. Relation of cross-section area of bath and meshed cassette has to be 1,4 and higher. Relation of height of liquid detergent in meshed cassette above false bottom and under it has to be 1,6 and higher. Meshed cassette with false bottom and piston of compression unit are made of perforated material having live section coefficient of 0,3 and higher.

EFFECT: reduced time for washing wool out; reduced consumption of water and detergent.
