Description

Rotary air flow guiding device

Technical field

The utility model relates to air flow guiding device, particularly rotary air flow guiding device.

Background technique

Air flow guiding device is fixed; Include suction tude and steam outlet pipe; Suction tude and steam outlet pipe are to be fixed together, and the steam outlet pipe that has is provided with a plurality of bronchuses, can not rotate relatively between suction tude and the steam outlet pipe; The water conservancy diversion work of suction tude and steam outlet pipe completion gas in relative rotary course can't be realized, thereby the operations specific demand can not be satisfied.

The model utility content

The purpose of the utility model provides a kind of suction tude and steam outlet pipe can counterrotating rotary air flow guiding device.

The utility model technological scheme is to accomplish like this; Rotary air flow guiding device; Include suction tude, steam outlet pipe; The ladder pipe is followed successively by steam outlet pipe, mechanical seal pipe, bushed bearing composition from top to bottom, and the diameter of bore of bushed bearing is greater than the diameter of bore of mechanical seal pipe, and the diameter of bore of mechanical seal pipe is greater than the diameter of bore of steam outlet pipe; Be provided with mechanical seal in the mechanical seal pipe, the moving ring sleeve of mechanical seal is on suction tude, and the stationary ring of the mechanical seal that is fixedly connected with the mechanical seal seal of tube is blocked by the interior step that forms between steam outlet pipe and the mechanical seal pipe; Bushed bearing and suction tude are rotatably connected through bearing, and the bearing that is located in the bushed bearing is blocked by the interior step that forms between mechanical seal pipe and the suction tude, is used to stop that the hole of bearing axial motion is located in the jump ring groove of bushed bearing lower end with jump ring.The mechanical seal pipe is screwed onto with bushed bearing.The mechanical seal pipe is screwed onto with steam outlet pipe.Be used to stop that the axle that mechanical seal is axially moved is located in the jump ring groove on the suction tude between mechanical seal and the bearing with jump ring.Suction tude and bushed bearing in the bushed bearing are rotatably connected through two bearings.The suction tude of upper end sealing is provided with a plurality of bronchuses.Said bronchus has 8 or 12 or 14.The mechanical seal tube outside is welded with flange plate.

The technique effect of the utility model is: because of the suction tude and the steam outlet pipe ability relative rotary motion of the utility model, in the process of rotation, accomplish gas flow guiding, can satisfy the operations specific demand; The interflow that also can be used for each bronchus input gas; Because of suction tude and steam outlet pipe are pipe, also can be used for the shunting or the interflow of liquid; When free-flowing powder shape thing transmits from top to bottom, also can be used for the shunting or the interflow of free-flowing powder shape thing.Owing to be provided with mechanical seal between suction tude and the ladder pipe, can effectively prevent the leakage of gas in the rotary course.
