DEVICE FOR LOCAL HEATING AND INTAKE OF BITUMEN FROM STORAGE Russian patent published in 2009 - IPC E01C19/08 

FIELD: construction, highway engineering.

SUBSTANCE: invention is related to construction of automobile roads, in particular to facilities for storage and heating of bitumen. Substance of invention consists in the fact that device of local heating and intake of bitumen from storage, comprising body on legs and loading points on its side surface, movable module suspended inside the body on springs, which represents frame with sections of ribbed heating coils, on top of which the following components are symmetrically fixed: frame with plate and vibrator, suction nozzle of bitumen pump and temperature detector, besides device body has sector bottom from sectors displaced at equal distance relative to each other and bent along axis, bent edges of which are directed inside the body; loading points that are covered by visors to their lower edge from external side of body are located in several rows, at that lower row of loading points starts from level of upper heating coils; heating coils sections are removable and are displaced in frame by height and relative to each other, and frame rests on springs in sleeves fixed in lower part of body.

EFFECT: reduction of power inputs by filling of the device with heated bitumen from layers adjacent to device body and reduction of heating time, and also exclusion of device lifting and lowering operations executed by operator.
