Description
Technical field
The present invention relates to a kind of horizontal fluidised devices for low-pressure pneumatic conveying.
Background technique
Pneumatic conveyer is a kind of transport device conveyed in closed pipeline to material using air energy.
It draws off mechanism etc. by material access mechanism, material conveying pipe and material and forms.Pneumatic conveyer is by the pressure in system
Generation type is divided into negative pressure transportation and positive pressure conveying；Dilute phase gas can be divided by the mass concentration ratio of solid-gas phase in conveyance conduit
Power conveying and Dense Phase Pneumatic Conveying.But either dilute phase pneumatic conveying or Dense Phase Pneumatic Conveying often exist during transportation
Material sedimentation the problem of, it is especially the most obvious with dilute phase pneumatic conveying, when occur material sedimentation when blower pressure can increase suddenly,
Transportation system can be suppressed directly extremely when serious.The present invention provides a kind of horizontal fluidised device for low-pressure pneumatic conveying, main mesh
Be so that material can not settle, and then to improve low-pressure pneumatic by installing the device additional in the position that material is easy sedimentation
The conveying distance of conveying.
Summary of the invention
To overcome drawbacks described above, the purpose of the present invention is to provide one kind to make material that can not sink in predetermined position
Drop, the horizontal fluidised device for low-pressure pneumatic conveying.
In order to achieve the above objectives, the horizontal fluidised device of low-pressure pneumatic conveying of the present invention, comprising:
Charging interface, discharging interface and the interior tube being co-axially located between charging interface, discharging interface；Charging connects
Side between mouth, discharging interface passes through connector and connects；Interior tube can be relative to charging interface, discharging interface rotation；
The driving device of tube rotation in driving is provided in the connector or outside connector；
The driving device and the interior tube are sequentially connected.
Preferably, side is connected by outer tube hermetic seal between the charging interface, discharging interface；Described
Air inlet is provided on outer tube, the air inlet is used to connect the gas of high pressure.
Preferably, the interior tube outer surface is provided with worm gear；The driving device is motor, in the electricity
Worm screw is installed on arbor；The worm screw is meshed with the worm gear.
Preferably, annular convex platform is circumferentially provided in the charging interface, discharging interface opposite side；Described is interior
The both ends of tube are co-axially located in or beyond annular convex platform by floating bearing.
Preferably, there is helical baffle interior tube inner surface is axially disposed.
Preferably, in the axially disposed screw pitch for having helical baffle of interior tube inner surface less than 1.
Advantages of the present invention is as follows:
(1) material can be made constantly to throw from bottom to top in the air, so that material remains fluidised form when interior tube rotates
Change, increases gas conveying distance；
(2) there is helical baffle on interior tube, so that the gas in pipe is become spiral wind from laminar winds, be further reduced in pipe
Air resistance increases the distance of material conveying；
(3) there are air inlets on outer tube, and barotropic gas can be passed through by air inlet, form air seal and prevent gas
It carries material and scurries into floating bearing；
(4) interior tube is passed through worm screw and is integrated to be driven with the turbine on interior tube and turned round from motor, is had
Have that structure is simple, transmission is efficient.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the A-A schematic cross-sectional view of Fig. 1
Specific embodiment
Referring to Fig. 1, the present invention for low-pressure pneumatic conveying horizontal fluidised device include charging interface 1, discharging interface 4 with
And charging interface, discharging interface between interior tube 3 be coaxially disposed, it is two neighboring between push against contact, to prevent material from leaking
Out；The side fed between interface, discharging interface is connected by connector, so that charging interface and discharging interface are relatively solid
It is fixed；Interior tube can be relative to charging interface, discharging interface rotation；
The driving device of tube rotation in driving is provided in the connector or outside connector；The driving dress
It sets and is sequentially connected with the interior tube, so that driving device drives interior tube rotation.Interior tube can make material when rotating
It constantly throws from bottom to top in the air, so that material remains fluidization, increases gas conveying distance.
Below with reference to embodiment, the present invention is further illustrated.
Fig. 1 and Fig. 2 show this bright embodiment, as shown, the present invention is used for the level stream of low-pressure pneumatic conveying
Change device, comprising: charging interface 1, outer tube 2, interior tube 3, discharge port 4, motor 5, floating bearing 6, sealing ring 7, worm screw 8,
Turbine 9, air inlet 10, helical baffle 11, which assemble, forms a kind of horizontal fluidised device for low-pressure pneumatic conveying.
Side passes through 2 hermetic seal of outer tube connection between the charging interface 1, discharging interface 4；In the housing
Air inlet 10 is provided on pipe 2, the air inlet 10 is used to connect the gas of high pressure.It can be passed through just by air inlet in this way
It calms the anger body, forms air seal gas is prevented to carry material and scurry into floating bearing 6；
In figure, the interior tube outer surface is provided with worm gear 9；The driving device is motor, in the electricity
Worm screw 8 is installed on arbor；The worm screw is meshed with the worm gear.Interior tube by worm screw and is integrated in by motor
