Abstract
The utility model belongs the filed of dust removers, and discloses a fluidized bed dust remover man hole seal device which comprises a man hole which is arranged in the box wall of a dust remover, a shell ring is fixed on the periphery of the man hole, the periphery of the end portion of the shell ring is provided with a shell ring flange, a bushing is arranged inside the shell ring in concentric mode, a bushing flange is fixed on the outer end portion of the bushing, the shell ring flange and the bushing flange are fixed together through a bolt, and the inner end portion of the bushing is sealed through a seal plate. According to the fluidized bed dust remover man hole seal device, the bushing is arranged inside the shell ring on the periphery of the man hole, the seal plate is arranged on the inner end portion of the bushing, material is prevented from being accumulated in the shell ring, and therefore a worker can enter into a box to conduct maintenance conveniently, and the fluidized bed dust remover man hole seal device can be used in a fluidized bed dust remover.
Description
Technical field
The utility model relates to a kind of deduster, particularly a kind of fluid bed deduster.
Background technology
At present, the fluid bed deduster adopts solid fluidization technology to realize the dedusting of granule materials, is widely used in the granular material dedusting of the industrial circles such as chemical industry, medicine, food, light industry, mining and metallurgy, power.Fluid bed deduster of the prior art is provided with manhole, manhole is as the maintenance through hole, be usually used in all kinds of large pressurized vessels, because the periphery of manhole of the prior art is fixed with shell ring, the end periphery of described shell ring is provided with the shell ring flange, on the shell ring flange sealing plate is installed, its weak point is, because the periphery of manhole is provided with shell ring on the dust cleaning case, this just so that material in dust removal process in shell ring easy buildup, serious can be with people's hole plug, enter and carry out repair and maintenance in the casing thereby affect the staff.
The utility model content
The purpose of this utility model is for the susceptible to plugging problem in deduster manhole of the prior art place, and a kind of fluid bed deduster manhole sealing device is provided, and has avoided manhole to stop up, so that the staff is convenient when entering the casing repair and maintenance.
The purpose of this utility model is achieved in that a kind of fluid bed deduster manhole sealing device, comprise the manhole that is opened on the deduster tank wall, the periphery of described manhole is fixed with shell ring, the end periphery of described shell ring is provided with the shell ring flange, be provided with one heart lining in the described shell ring, the outer end of lining is fixed with the lining flange, and described shell ring flange and lining flange are through being bolted to together, and the inner end of described lining seals through shrouding.
Compared with prior art, the beneficial effects of the utility model are, the utility model is by being equipped with lining in the shell ring of manhole periphery, inner end at lining arranges shrouding, avoided material that buildup occurs in shell ring, thereby so that the staff is convenient during repair and maintenance in entering casing.The utility model can be used in the fluid bed deduster.
As further improvement of the utility model, described shrouding inner plate surface is concordant with the deduster chamber interior wall.So that dust cleaning case inwall flatness is higher, so that dust removing effects is better.
As further improvement of the utility model, be provided with handle on the outer plate surface of described shrouding.So that dismounting is convenient during lining.
As further improvement of the utility model, the external diameter of described shrouding is greater than the external diameter of lining and less than the internal diameter of shell ring.Avoid material to enter shell ring and lining gap, improve sealing effectiveness.
As further improvement of the utility model, the gap between the outer wall of described lining and the inwall of shell ring is less than 2mm.Further improve sealing effectiveness.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 tank wall, 2 bolts, 3 shell ring flanges, 4 shell rings, 5 handles, 6 shroudings, 7 linings, 8 lining flanges.
The specific embodiment
A kind of fluid bed deduster manhole sealing device as shown in Figure 1, comprise the manhole that is opened on the deduster tank wall 1, the periphery of manhole is fixed with shell ring 4, the end periphery of shell ring 4 is provided with shell ring flange 3, the shell ring 4 interior linings 7 that are provided with one heart, the outer end of lining 7 is fixed with lining flange 8, shell ring flange 3 and lining flange 8 are fixed together through bolt 2, the inner end of lining 7 is through shrouding 6 sealings, shrouding 6 inner plate surfaces are concordant with the deduster chamber interior wall, be provided with handle 5 on the outer plate surface of shrouding 6, the external diameter of shrouding 6 is greater than the external diameter of lining 7 and less than the internal diameter of shell ring 4, the gap between the inwall of the outer wall of lining 7 and shell ring 4 is less than 2mm.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection domain of the present utility model.
