The device comprises filter screens, an outer cover pipe, a collecting pipe 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 collecting pipe is installed at the bottom of the outer cover pipe; a circle of jet pipes are also installed in the outer cover pipe; and the jet directions of the jet pipes face the inner walls of the outer cover pipe. The device has the beneficial effects that the jet pipes are utilized to carry out online dust collection on the inner walls of the outer cover pipe, thus ensuring that accumulation can not be caused inside the outer cover pipe, keeping the flow field unimpeded, reducing the labor intensity of workers and 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 a kind of band Flushing nozzle filter screen, utilize playpipe that the outer tube inwall is carried out online dedusting, guarantee that outer tube inside can't form packing phenomenon, keep the unblocked of flow field, well guaranteed the efficient of suction.
The utility model is achieved in that the online rotating dust removing device of a kind of band Flushing nozzle 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, one circle playpipe also is housed in the described outer tube, and the injection direction of described playpipe is towards the inwall of outer tube.
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 band Flushing nozzle 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; Recycle simultaneously playpipe the outer tube inwall is carried out online dedusting, guarantee that outer tube inside can't form packing phenomenon, keep the unblocked of flow field; This apparatus structure is compact, simple, realizes the lasting high-effective dust-removing of dust arrester, has reduced labor strength, has 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 the structural representation of the online rotating dust removing device of the utility model band Flushing nozzle filter screen.
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.
