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, easily cause 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 helical flow path filter screen, this device is provided with the spiral stream guidance groove at the outer tube inwall, utilize the rotation of spiral stream guidance groove guiding suction airflow, take full advantage of the regional of screen pack, improved the effect of filtering.
The utility model is achieved in that the online rotating dust removing device of a kind of helical flow path 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, and described outer tube inwall is provided with the spiral stream guidance groove.
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.
Screen pack in the online rotating dust removing device of the utility model helical flow path filter screen when carrying out dust removal by filtration because self High Rotation Speed, the dust of screen pack absorption can in time throw away the screen pack surface, the cleaning surfaces of assurance sieves, unimpeded guarantees that the flow field of gas does not cause pumping efficiency to reduce because screen pack stops up; Suction airflow is rotated in outer tube under the guiding of spiral stream guidance groove, takes full advantage of the regional of screen pack, has improved the effect of filtering, and can well guarantee suction efficient.
