BITUMEN STORAGE Russian patent published in 2004 - IPC

FIELD: highway engineering.

SUBSTANCE: the invention is dealt with the field of highway engineering, in particular, with means of storage and heat of bitumen. The technical result is reduction of duration of dehydration process, preservation of quality of bitumen and decrease of power inputs due to decrease of intake of a moisture with bitumen at filling the pit of the storehouse, and also provision of possibility for intake of bitumen of the required mark from interlayers of the storage. In the wall between the storehouse of bitumen and the pit there is a discharge spout of rectangular form on height from the bottom of the storehouse and up to the level, defined by maximum filling of bitumen in the storehouse and closed by several gate valves of the similar rectangular form with independent devices of their relocation and placed in series one after another. The front wall of each following gate valve, beginning from above from the second gate valve is shifted in parallel in respect to the front wall of the previous gate valve by thickness of a gate valve in direction of the rear wall of a pit.

EFFECT: reduction of duration of dehydration process, preservation of quality of bitumen and decrease of power inputs.
