Description

Rotary type gas flow guide device

Technical field

The present invention relates to air flow guiding device, particularly rotary type gas flow guide device.

Background technology

Air flow guiding device is fixed, include air inlet pipe and escape pipe, air inlet pipe and escape pipe are to be fixed together, some escape pipes are provided with multiple bronchuses, between air inlet pipe and escape pipe, can not relatively rotate, cannot realize air inlet pipe and in relative rotary course, complete the water conservancy diversion work of gas with escape pipe, thereby can not meet operations specific demand.

Summary of the invention

The object of this invention is to provide a kind of air inlet pipe and escape pipe can counterrotating rotary type gas flow guide device.

Technical solution of the present invention completes like this, rotary type gas flow guide device, comprise air inlet pipe, escape pipe, ladder pipe is followed successively by escape pipe, mechanical seal pipe, bushed bearing from top to bottom, 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 escape pipe; In mechanical seal pipe, be provided with mechanical seal, the moving ring sleeve of mechanical seal is in air inlet pipe, and the stationary ring of the mechanical seal being fixedly connected with the mechanical seal seal of tube is blocked by the interior step forming between escape pipe and mechanical seal pipe; Bushed bearing and air inlet pipe are rotatably connected by bearing, and the bearing being located in bushed bearing is blocked by the interior step forming between mechanical seal pipe and air inlet pipe, are located in the jump-ring slot of bushed bearing lower end for the hole jump ring that stops bearing axially-movable. Mechanical seal pipe and bushed bearing are screwed together. Mechanical seal pipe and escape pipe are screwed together. For stopping that the axle jump ring that mechanical seal is axially moved is located in the jump-ring slot in the air inlet pipe between mechanical seal and bearing. Air inlet pipe in bushed bearing and bushed bearing are rotatably connected by two bearings. The air inlet pipe of upper end sealing is provided with multiple bronchuses. Described bronchus has 8 or 12 or 14. Mechanical seal tube outside is welded with ring flange.

Technique effect of the present invention is: because of air inlet pipe of the present invention and escape pipe energy relative rotary motion, in the process of rotation, complete gas flow guiding, can meet operations specific demand; Also can be for the interflow of each bronchus input gas; Because air inlet pipe and escape pipe are tube, also can be used for shunting or the interflow of liquid; In the time that free-flowing powder shape thing transmits from top to bottom, also can be for shunting or the interflow of free-flowing powder shape thing. Owing to being provided with mechanical seal between air inlet pipe and ladder pipe, can effectively prevent the leakage of gas in rotary course.

In figure: l, bronchus; 2, escape pipe; 3, mechanical seal; 4, ring flange; 5, mechanical seal pipe; 6, snap ring; 7, bearing; 8, bushed bearing; 9, air inlet pipe; 10, snap ring.

Detailed description of the invention

By reference to the accompanying drawings the present invention is described in further detail, rotary type gas flow guide device, it includes air inlet pipe 9, escape pipe 2, ladder pipe is followed successively by from top to bottom escape pipe 2, mechanical seal pipe 5, bushed bearing 8 and forms, the diameter of bore of bushed bearing 8 is greater than the diameter of bore of mechanical seal pipe 5, and the diameter of bore of mechanical seal pipe 5 is greater than the diameter of bore of escape pipe 2; In mechanical seal pipe 5, be provided with mechanical seal 3, the moving ring sleeve of mechanical seal 3 is in air inlet pipe 9, and the stationary ring of the mechanical seal 3 that is sealedly and fixedly connected of mechanical seal pipe 5 is blocked by the interior step forming between escape pipe 2 and mechanical seal pipe 5; Bushed bearing 8 is rotatably connected by bearing 7 with air inlet pipe 9, and for improving the stability in rotation process, the air inlet pipe 9 in bushed bearing 8 is rotatably connected by two bearings with bushed bearing 8; The bearing 7 being located in bushed bearing 8 is blocked by the interior step forming between mechanical seal pipe 5 and air inlet pipe 2, is located in the jump-ring slot of bushed bearing lower end for the hole jump ring 10 that stops bearing 7 axially-movables; In jump-ring slot in the air inlet pipe being located between mechanical seal and bearing for the axle jump ring 6 that stops mechanical seal 3 axially-movables; The escape pipe 2 of upper end sealing is provided with multiple bronchus l. According to actual job needs, bronchus can be offered 8 or 12 or 14. For ease of installing, can, at the outside of bushed bearing welding flange 4, ring flange be fixed in the frame of slewing.

For the ease of processing and installation, bushed bearing 8 can be screwed together with mechanical seal pipe 5; Mechanical seal pipe 5 also can be screwed together with escape pipe 2. In use, air inlet pipe and air feed equipment are sealedly and fixedly connected, and each bronchus is connected with the equipment that needs gas respectively.
