SEPARATION DEVICE Russian patent published in 2017 - IPC B04B1/00 B04B9/00 

FIELD: machine engineering.

SUBSTANCE: separation device for the product processing in continuous mode contains the rotatable drum, disposed in the sub-chamber and having the vertical axis of rotation, at that the mentioned drum is mounted on the drive spindle, configured rotatable, the drive chamber containing one, several or all of the separator drive components. At the same time, the sub-chamber is sealed with respect to the external environment and, during the operation, it is possible to create the negative pressure in the sub-chamber with respect to the external environment outside the sub-chamber with at least one device, capable to create the negative pressure, in particular the pump. The negative pressure joint is made under the solid state channel and the outlet of the solid phase trap. According to the first version of the separation device operating method, the negative pressure in the sub-chamber is changed during its operation. According to the second version of the separation device operating method, the negative pressure in the sub-chamber is changed depending on the actual or expected operating mode during its operation. According to the third version of the separation device operating method, the pressure in the sub-chamber is raised before the solid phase discharge.

EFFECT: energy saving provision on the rotating parts in the areas, where the negative pressure is created in comparison with the external environment.
