Abstract

The utility model relates to the field of filtering and dust removing, and particularly relates to a filter screen on-line dust removing device. A spherical filter screen on-line rotary dust removing device comprises a filter screen, an outer cover pipe, a collection pipe and a centrifuger, wherein an opening is formed in the top axle center of the outer cover pipe to enable the outer cover pipe to be communicated with a suction outlet pipe; the side wall of the outer cover pipe is communicated with a suction inlet pipe; the filter screen is arranged in the outer cover pipe; the suction outlet pipe is connected with the top of the filter screen through a bearing; the bearing is arranged between the outer wall of the suction outlet pipe and the inner wall of the outer cover pipe; the centrifuger drives the bearing through a transmission mechanism; the collection pipe is mounted at the bottom of the outer cover pipe. The device is characterized in that the upper part of the filter screen is cylindrical; the lower part of the filter screen is hemispherical; the upper part and the lower part of the filter screen are connected as a whole. The filter screen of the spherical filter screen on-line rotary dust removing device is a whole body, totally covers the passage of the air exhausting flow, does not have a filtration dead zone, spins off the dust on the filter screen by utilizing the rotating of the centrifuger, and ensures the suction efficiency well.

Description

The online rotating dust removing device of spherical filter screen
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 spherical filter screen, and the screen pack in this device is as a whole, has covered the passage of pumping airflow fully, without filtering the blind area, has well guaranteed the efficient of suction.
The utility model is achieved in that the online rotating dust removing device of a kind of spherical 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 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, it is characterized in that: screen pack is that top is cylindrical, and the screen pack bottom is hemispherical, and the upper and lower of screen pack is as a whole.
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 screen pack of the online rotating dust removing device of the spherical filter screen of the utility model is as a whole, has covered the passage of pumping airflow fully, without filtering the blind area, utilizes the rotation of centrifuge to get rid of dust on the screen pack, 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 spherical 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.
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 spherical 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 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 by transmission mechanism band dynamic bearing 12, collecting pipe 8 is installed in the bottom of outer tube 7, it is characterized in that: screen pack 2 is cylindrical for top, screen pack 2 bottoms are hemispherical, and the upper and lower of screen pack 2 is as a whole; In the present embodiment, described centrifuge 9 is electric rotating machine, described transmission mechanism is gear drive, the output shaft driven gear transmission mechanism of electric rotating machine, so that screen pack 2 High Rotation Speeds are dropped the dust of screen pack 2 surface adhesion, realize the online ash removal to screen pack 2, all-in-one-piece screen pack 2 has best air-flow effect, so that suction airflow is more smooth.
