Description
Technical field
The present invention relates to dust settling pocket technical field of sealing technology, be specially a kind of dust settling pocket sealing device.
Background technology
The equipment that dust is separated from flue gas is cleaner unit or cleaner.The performance of cleaner unit with accessible gas flow, gas by cleaner unit time drag losses and efficiency of dust collection express.Meanwhile, the price of cleaner unit, operation and maintenance cost, service life length and operation management difficulty or ease also be consider its performance key factor.Cleaner unit has become as one of facility conventional in boiler and commercial production.Cleaner unit is of a great variety, various informative, and wherein pulse flat bag dust remover has compact conformation, and floor space is little, combines the features such as flexible, stable and reliable for performance, replacing filter bag is light, is the horizontal insertion flat bag deduster of current latest domestic type.Its operation principle is that dusty gas is entered dust collector ash hopper by air inlet, the dust that a part of granule is bigger is fallen into ash bucket by action of gravity, remaining dust reduces suddenly because of air-flow, then it is adsorbed on the outer surface of filter bag, when the grit of filter bag outer wall is continuously increased, dust remover resistance is made constantly to increase, in order to ensure that the draught control of cleaner unit is within the scope limited, signal is sent by pulse control instrument, partially unrolling electromagnetic impulse valve, the compression air in gas bag is made to be ejected in the filter bag of correspondence by injection hole each in injection tube, thus filter bag moment sharply expands, percussion due to reverse impulse air-flow, quickly disappear, filter bag sharply shrinks again, so expand, shrink, the long-pending grit being attached on filter bag outer wall is made to be cleaned, the dust fallen into is discharged through ash-valve.In flat sack cleaner, it is necessary to carry out pulsed drive, owing to the vibration of its working environment is relatively big, common sealing device tends to reduce sealing effectiveness, even complete failure under the influence of vibrations, is presently required a kind of good dust settling pocket sealing device of sealing effectiveness.
Summary of the invention
It is an object of the invention to provide a kind of dust settling pocket sealing device, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme: a kind of dust settling pocket sealing device, including main fixed body and primary seal post, described main fixed body be internally provided with sealing plate, gap is left between described sealing plate and main fixed body, described gap is respectively arranged with primary seal post, sealing column one and sealing flange, gap between described sealing plate and primary seal post is provided with sealing gasket one and sealing gasket two, it is provided with magnetic induction coil in the middle part of the outer surface of described sealing column one, gap between described close primary seal post and sealing column one is provided with sealing gasket three, sealing gasket two it is provided with between described sealing flange and main fixed body and primary seal body, gap between described main fixed body and sealing column one is provided with sealing gasket two.
Preferably, the symmetrical configuration of described sealing plate both sides.
Preferably, described sealing gasket one, sealing gasket two and sealing gasket three are made by natural rubber.
Preferably, described magnetic induction coil is looped around the outer surface of sealing column one in the shape of a spiral.
Compared with prior art, the invention has the beneficial effects as follows: this dust settling pocket sealing device, it is combined into ground floor closed structure by sealing column one and sealing gasket three, again through sealing flange, primary seal post, sealing column one and sealing gasket two and airtight pad three are combined into the second layer and seal structure, make device obturation effect better, by arranging magnetic induction coil at the outer surface of sealing column one, the metal above filter bag can be attracted, strengthen sealing effectiveness, gap between main fixed body and sealing column one arranges sealing gasket two, gap between primary seal post and sealing column one is provided with sealing gasket three, the size of vibration can be reduced, thus reaching the close effect strengthening envelope.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
In figure: 1 main fixed body, 2 primary seal posts, 3 sealing column one, 4 magnetic induction coils, 5 sealing gasket one, 6 gaps, 7 sealing gasket two, 8 sealing gasket three, 9 sealing plates, 10 sealing flanges.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
nullRefer to Fig. 1，The present invention provides a kind of technical scheme: a kind of dust settling pocket sealing device，Including main fixed body 1 and primary seal post 2，Main fixed body 1 be internally provided with sealing plate 9，The symmetrical configuration of sealing plate 9 both sides，Gap 6 is left between sealing plate 9 and main fixed body 1，Gap 6 is respectively arranged with primary seal post 2、Sealing column 1 and sealing flange 10，Gap between sealing plate 9 and primary seal post 2 is provided with sealing gasket 1 and sealing gasket 27，Magnetic induction coil 4 it is provided with in the middle part of the outer surface of sealing column 1，Magnetic induction coil 4 is looped around the outer surface of sealing column 1 in the shape of a spiral，The metal above filter bag can be attracted，Strengthen sealing effectiveness，Make the magnetic force that magnetic induction coil 4 produces more uniform，Gap between close primary seal post 2 and sealing column 1 is provided with sealing gasket 38，Sealing gasket 27 it is provided with between sealing flange 10 and main fixed body 1 and primary seal body 2，Gap between main fixed body 1 and sealing column 1 is provided with sealing gasket 27，Sealing gasket 1、Sealing gasket 27 and sealing gasket 38 are made by natural rubber，There is the effect of vibration damping，The size of vibration can be reduced，Sealing column 1 and sealing gasket 38 are combined into ground floor closed structure，Again through sealing flange 10、Primary seal post 2、Sealing column 1、Sealing gasket 27 and airtight pad 38 are combined into the second layer and seal structure，Make device obturation effect better，Thus reaching the effect sealed.
