DEVICE FOR LOCAL AIR DISTRIBUTION INTO PROCESS ZONE OF SPINNING EQUIPMENT Russian patent published in 2010 - IPC D01H11/00 

FIELD: textile, paper.

SUBSTANCE: device may be used in various technological processes of textile industry for local distribution of plenum air directly into process zone of equipment in order to develop and maintain required parametres of microclimate required to make high-quality products. Device is installed over supply frame of spinning machine, directly into process equipment, and represents air duct without upper channel for air outlet, cross section of which reduces along with air motion. Air duct comprises walls arranged in the form of flat screens with longitudinal slits for air passage, arched screens with longitudinal slots, edges of which are bent along with air flow motion, and reflecting planks connected to walls of air duct by means of plate separators of air flow. Longitudinal slots of plate separators are bent along with air motion to arrange two air-directing channels between each reflecting plank and external walls of air duct, having holes, these channels are oppositely directed in cross section of air duct to provide for collision of air flows and their outlet into process zone along channels formed between longitudinal edges of neighbouring reflecting planks. At inner side of air duct walls there are additional arched screens with longitudinal slots arranged in a row, and in external walls of air duct there are longitudinal slots arranged in two rows, in staggered order relative to slots of arched screen.

EFFECT: increased extent of plenum jet attenuation, reduced resistance, provision of smoother and more even outlet of air from air distributor into process zone of textile equipment and reduction of its flow rate.
