DEVICE FOR LOCAL BITUMEN HEATING AND INTAKE FROM STORAGE FACILITY Russian patent published in 2006 - IPC E01C19/08 C10C3/12 

FIELD: motor road building, particularly bitumen storage and heating means.

SUBSTANCE: device comprises body with legs and chutes, as well as heating members, vibratory means and suction pipe of exhaust bitumen pump. The body does not have bottom and is provided with additional chutes arranged in upper body part. Fixed tubular electric heater modules are located in lower body part. Movable tubular electric heater modules are suspended over fixed ones with the use of springs. The moveable tubular electric heaters are connected with vibratory means in predetermined way. The vibratory means are supported by frame installed over the body and connected to upper body part. Movable and fixed modules are composed of ribbed tubular electric heaters.

EFFECT: reduced power inputs due to increased bitumen heating rate with the use of vibratory bitumen heaters, which reduce bitumen heating time, and due to decreased losses of heat from local pit plane, prevention of moisture ingress in bitumen due to surface bitumen intake and, as the result, elimination of evaporation operation, possibility to retain initial bitumen properties and improved ecology.
