Abstract
The present invention relates to deduster technical field, disclose a kind of cyclone dust collectors, including dust removing drum, described dust removing drum top is provided with air inlet, and the bottom of dust removing drum is provided with dust collecting box, blast pipe is provided with inside described dust removing drum, described blast pipe is cylindrical structural, the outside of blast pipe is provided with spiral guide blade, and the bottom of described blast pipe is provided with the linear pattern guide vane of frustum cone structure, and the bottom inside of described round platform is provided with inverted cone.After air-flow of the present invention enters cyclone dust collectors, motion of being spinned downwards directly in the presence of guide vane, the formation of upper dust-ring restrained effectively；Dust granules are during rotating separation, and due to the presence of spiral guide blade, the dust granules inwardly moved can only fall the air-flow rotated at a high speed on blade to be kicked up and continue to separate again, without being discharged with interior air-flow；The presence of guide vane reduce air-flow because of rotation and caused by the pressure loss.
Description
Technical field
The present invention relates to deduster technical field, more particularly to a kind of cyclone dust collectors.
Background technology
Cyclone dust collectors are using centrifugal force caused by the dusty gas of rotation, and dust is separated from air-flow
A kind of dry type gas-solid separating device.Cyclone dust collectors are simple in construction as a kind of common gas-solid separating device, in practical application
During operation, the change adaptability of the factor such as easy to maintenance, stable performance, concentration and temperature to dusty gas it is stronger.Rotation
Wind deduster is mainly used in industrial dedusting, air sampling, selects powder, heat exchange etc..Current cyclone dust collectors are in dedusting
During, there is cyclone exchange because bottom is present between vortex, side wall and bottom centrum, all inevitably produce upper ash
Ring and reentrainment of dust, the gas with ash are discharged from exhaust outlet, reduce efficiency of dust collection, it is impossible to completely dust is divided from gas
Separate out.
The content of the invention
The present invention is for the halfway shortcoming of cyclone dust collectors dedusting in the prior art, there is provided a kind of cyclone dust collectors.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：
A kind of cyclone dust collectors, including dust removing drum, the top of described dust removing drum is cylinder, and bottom is to be connected with cylinder
Cone, described dust removing drum top is provided with air inlet, and the bottom of dust removing drum is provided with dust collecting box, set inside described dust removing drum
There is blast pipe, described blast pipe is cylindrical structural, and the outside of blast pipe is provided with spiral guide blade, described blast pipe
Bottom is provided with the linear pattern guide vane of frustum cone structure, and the bottom inside of described round platform is provided with inverted cone.
Preferably, the top of described dust removing drum is provided with top cover, bottom is provided with ash discharging hole.
Preferably, described inverted cone is directly connected in the inner side of round platform with blast pipe.
The present invention has significant technique effect as a result of above technical scheme：After air-flow enters cyclone dust collectors,
Spinned downwards directly in the presence of guide vane motion, restrained effectively the formation of upper dust-ring；Dust granules are rotating
During separation, due to the presence of spiral guide blade, the dust granules inwardly moved can only fall to be revolved at a high speed on blade
The air-flow turned is kicked up again to be continued to separate, without being discharged with interior air-flow；The presence of guide vane reduce air-flow because of rotation and
The caused pressure loss.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
The toponym that each number designation is referred in accompanying drawing is as follows：1-dust removing drum, 2-air inlet, 3-dust collecting box,
4-blast pipe, 5-spiral guide blade, 6-round platform, 7-inverted cone, 8-top cover, 9-ash discharging hole.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
A kind of cyclone dust collectors, as illustrated, including dust removing drum 1, the top of described dust removing drum 1 is cylinder, bottom
For the cone being connected with cylinder, the described top of dust removing drum 1 is provided with air inlet 2, and the bottom of dust removing drum 1 is provided with dust collecting box
3, the described inside of dust removing drum 1 is provided with blast pipe 4, and described blast pipe 4 is cylindrical structural, and the outside of blast pipe 4 is provided with spiral shell
Guide vane 5 is revolved, the bottom of described blast pipe 4 is provided with the linear pattern guide vane of the structure of round platform 6, the bottom of described round platform 6
Inverted cone 7 is provided with the inside of portion；Described inverted cone 7 is directly connected in the inner side of round platform 6 with blast pipe 4；Described dust removing drum 1
Top be provided with top cover 8, bottom is provided with ash discharging hole 9.
Air-flow from air inlet pipe enter deduster after in the presence of spiral guide blade 5 from transform linear motion be spiral to
Under circular motion, dusty gas produces very big centrifugal force in rotary course, because the density ratio air of grit is much larger
Times, therefore the grit rotated, under very big centrifugal action, separation is got rid of to wall, grit from air-flow once contacts with wall
Centrifugal action is just lost afterwards and rotates whereabouts along wall face with the gravitional force of itself by the kinetic energy of entrance velocity, is arranged through cone
Enter dust collecting box 3.When air motion is to close to the bottom surface of inverted cone 7, because dust removing drum is closed space, lower rotational gas flow can not
Continue backspin, and linear motion is converted into by screw in the presence of linear guide vane, discharged from blast pipe.
In a word, presently preferred embodiments of the present invention, all equalizations made according to scope of the present invention patent be the foregoing is only
Change and modification, it should all belong to the covering scope of patent of the present invention.
