Background technology
Need the dry tiny solid particle in the gas is carried out successional dedusting in some dust removal by filtration technique of factory, the dry tiny iron powder that dedusting obtains is to make ferromagnetic quality raw materials.Because the particle of iron powder is tiny, weight is small, very easily adheres to the lower surface of screen pack with the air of rapid flow, if in time do not clear up, can cause screen pack to stop up, and directly causes the suction channel inner flow velocity to reduce, and affects suction filtration efficient.Wherein some particle is because particle is tiny, traditional filter method as shown in Figure 1, filter at the suction channel 1 interior screen pack 2 that arranges, when screen pack 2 carries out simple suction filtration, cause easily screen pack 2 frequent jams, affect efficiency of dust collection, for guaranteeing the works fine characteristic of screen pack 2, just need to carry out frequently surface clean to it, produce usually use in order to purge convenient the cooperation, present blowing mechanism, by on screen pack 2 tops bracing frame 3 being set, at bracing frame 3 interior uniform fixing many rows' playpipes 4, each playpipe 4 following all has a series of equally spaced spray-holes in the face of screen pack 2, an end of each playpipe 4 is shut simultaneously, the other end is communicated with compressed air hose 6 by the independent electromagnetic relief valve of installing 5, its objective is the switch by control electromagnetic relief valve 5, fast to each playpipe 4 inner logical compressed air, compressed air is realized the purpose that the iron powder accumulated of screen pack 2 lower surfaces is removed fast after spraying to screen pack 2 by equally spaced spray-hole.This kind deashing mechanism is fixed owing to each playpipe 4 positions, and gapped between each playpipe 4, so it is very remarkable to purge the blind area, white space between two playpipes 2 is to spray the dead band, and the dust of herein piling up can't effectively be removed forever, causes the actual usable floor area of screen pack 2 to reduce, playpipe 4 is closely arranged and is equivalent to increase a windage part in addition, cause the flowing velocity of air to slow down, the draw resistance that more closely arrangement causes is larger, affects suction filtration efficient.
Summary of the invention
Technical problem to be solved in the utility model provides the online rotating dust removing device of a kind of outer winding-up filter screen, utilizes playpipe to the screen pack dedusting of jetting online, has guaranteed the unimpeded of screen pack, without spraying the dead band, has well guaranteed the efficient of suction.
The utility model is achieved in that the online rotating dust removing device of a kind of outer winding-up filter screen, comprise screen pack, outer tube, collecting pipe and centrifuge, axle center, top place's perforate of described outer tube is communicated with the suction outlet, the sidewall of outer tube is communicated with the suction inlet pipe, described screen pack is cylindrical being arranged in the outer tube, the top of screen pack links to each other with the suction outlet by bearing, bearing is arranged between suction outlet outer wall and the outer tube inwall, described centrifuge is by transmission mechanism band dynamic bearing, collecting pipe is installed in the bottom of outer tube, a vertical playpipe also is equipped with at described outer tube inwall top, playpipe is positioned at outside the screen pack, offer the equally spaced fumarole of a row on the described playpipe, the injection direction of described fumarole is towards screen pack.
Sealing plate is equipped with in the bottom of described screen pack.
Described centrifuge is electric rotating machine.
Described transmission mechanism is gear drive.
Also be provided with sealing ring between described bearing and the outer tube.
Described centrifuge is fixedly mounted on the outer wall of suction outlet by bracing frame.
The utility model online rotating dust removing device of filter screen of jetting outward utilizes playpipe to the screen pack dedusting of jetting, can thoroughly remove the dust that got rid of by centrifugal force of failing on the screen pack, utilize the rotation of screen pack self to eliminate the injection dead band, well guaranteed the efficient of suction.
Description of drawings
Fig. 1 is the structural representation of the existing online dust arrester of screen pack;
Fig. 2 is jet the outward structural representation of the online rotating dust removing device of filter screen of the utility model.
Among the figure: 1 suction channel, 2 screen packs, 3 bracing frames, 4 playpipes, 5 electromagnetic relief valves, 6 compressed air hoses, 7 outer tubes, 8 collecting pipes, 9 centrifuges, 10 suction outlets, 11 suction inlet pipes, 12 bearings, 13 sealing rings, 14 bracing frames, 15 sealing plates.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model statement, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
As shown in Figure 2, the online rotating dust removing device of a kind of outer winding-up filter screen, comprise screen pack 2, outer tube 7, collecting pipe 8 and centrifuge 9, axle center, top place's perforate of described outer tube 7 is communicated with suction outlet 10, the sidewall of outer tube 7 is communicated with suction inlet pipe 11, described screen pack 2 is cylindrical being arranged in the outer tube 7, the top of screen pack 2 links to each other with suction outlet 10 by bearing 12, bearing 12 is arranged between suction outlet 10 outer walls and outer tube 7 inwalls, described centrifuge 9 is fixedly mounted on the outer wall of suction outlet 10 by bracing frame 14, centrifuge 9 is by transmission mechanism band dynamic bearing 12, collecting pipe 8 is installed in the bottom of outer tube 7, a vertical playpipe 4 also is equipped with at described outer tube 7 inwall tops, playpipe 4 is positioned at outside the screen pack 2, offers the equally spaced fumarole of a row on the described playpipe 4, and the injection direction of described fumarole is towards screen pack 2, playpipe 4 is communicated with the compressed air hose of outside, is controlled by electromagnetic relief valve.
