Abstract
The utility model relates to the field of dust collection by filtration and in particular relates to an online filter screen rotary dust collection device with a flow aiding fan. The device comprises filter screens, an outer cover pipe, a fan and a centrifuge, wherein an opening formed in the axis at the top of the outer cover pipe is communicated with a suction outlet pipe; the side wall of the outer cover pipe is communicated with a suction inlet pipe; the filter screens are cylindrical and are arranged in the outer cover pipe; the tops of the filter screens are connected with the suction outlet pipe by bearings; the bearings are arranged between the outer walls of the suction outlet pipe and the inner walls of the outer cover pipe; the centrifuge drives the bearings via a transmission mechanism; the fan is installed on the axis at the bottom of the outer cover pipe; and the blowing surface of the fan faces openings at the bottoms of the filter screens. The device has the beneficial effects that due to the high-speed rotation of the filter screens while the filter screens are used for dust collection by filtration, the dust adsorbed by the filter screens can be timely thrown off the surfaces of the filter screens, thus ensuring the surfaces of the filter sieves to be clean and unimpeded; and the fan at the bottom of the outer cover pipe aids a suction airflow in flowing, thus well ensuring the suction efficiency.
Description
Technical field
The utility model relates to the dust removal by filtration field, relates in particular to the online dust arrester of a kind of filter screen.
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 filter screen that a kind of band helps flow fan, this device arranges a fan in the bottom of outer tube, flowing of auxiliary suction air-flow keeps the unblocked of flow field, well guaranteed the efficient of suction.
The utility model is achieved in that a kind of band helps the online rotating dust removing device of filter screen of flow fan, comprise screen pack, outer tube, fan 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, fan is installed in the place, axle center, bottom of outer tube, and the blowing face of fan is towards the bottom opening of 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 band helps screen pack in the online rotating dust removing device of the filter screen of flow fan when carrying out dust removal by filtration because the High Rotation Speed of self, 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; The bottom of outer tube arranges a fan more simultaneously, and flowing of auxiliary suction air-flow well guaranteed the efficient of suction.
