WASHING MACHINE OF THE CONTINUOUS OPERATION FOR THE GROUND WASTES OF THE POLYMERIC MATERIALS Russian patent published in 2007 - IPC B29B17/00 

FIELD: chemical industry; other industries; equipment for washing of the wastes of the ground polymeric materials.

SUBSTANCE: the invention is pertaining to the equipment for washing of the wastes of the ground polymeric materials. The washing machine of the continuous operation for the ground polymers wastes consists of two divided by the sealed partition tanks - the washing tank made in the form of the semi-cylinder, inside which there is the shaft with the activators and the shaft equipped with the rotary drive and the loading funnel, and the separation tank equipped with the raised bevel in the direction of the washed raw movement by the transporting feed screw with the drive of its rotation and with the holey underpan installed under the feed screw. The activators are made in the form of the rectangular vanes installed bevel to the shaft axis of the washing tank in such a way, that they are the components of the feed screw providing transportation of the ground polymeric wastes along the washing tank to the unloading device. The unloading device is represented by the unloading funnel and the perforated scoops concentrically fixed on the shaft of the washing tank. The separation tank is equipped with the partition separating the zone acceptance of the washed polymeric material from the remaining unit of the tank. The tanks of the washing machine are supplied with the electric heaters and are coated with the thermoinsulating coating. The invention ensures the qualitative washing of the ground polymeric materials wastes with simultaneous separation of admixtures and other substances with density less than 1 g/cm³.

EFFECT: the invention ensures the qualitative washing of the ground polymeric materials wastes with simultaneous separation of admixtures and other substances with density less than 1 g/cm³.
