Description
Technical field
The utility model is related to blast furnace gas dust collector manhole technical field, and in particular to a kind of double-deck accumulatingdust manhole.
Background technology
Manhole, manhole, sewer access hole：Thus a kind of duct for often carrying lid, people hole turnover can arrange road, pot
Stove, downcomer, also have include the light current well that telecommunications, cable television are used, inner passage of large bridge maintenance etc..Mainly
For people's discrepancy maintenance.
Blast furnace gas dust collector manhole is in maintenance for personnel by being operated and checking.But because manhole cover is recessed in removing
Dirt device housing, not with shell of dust remover same plane, causes easy dust stratification in manhole.Moisture is high, under grey glutinous serious conditions, glue
The ash for connecing is caused to open and used even by people's hole plug.
Utility model content
For above-mentioned technical problem, the purpose of this utility model is to provide a kind of double-deck accumulatingdust manhole, and the manhole is opened
Open facility, not dust stratification, at the same avoid moisture is high, under grey glutinous serious conditions, the ash of bonding is by people's hole plug so as to cause
The drawbacks of manhole cannot be opened.
To achieve the above object, technical solution adopted in the utility model is：
A kind of double-deck accumulatingdust manhole, it is characterised in that：It includes shell ring, flange, blind flange, cover plate and connection ring flat-plate；
Upper end on the outside of the shell ring is welded with flange, mounting flange lid on flange, and pad is provided between the flange and blind flange, and
And be fastenedly connected by bolt or bearing pin between flange and blind flange；The shell ring inwall is welded with connection ring flat-plate, connection ring
Cover plate is installed, cover plate is concordant with shell of dust remover on plate, sealing ring, and cover plate are provided between the cover plate and connection ring flat-plate
It is fastenedly connected by bolt or bearing pin with being connected between ring flat-plate.
The cover plate lower surface is provided with Wear-resistant heat insulation layer liner.
Raise up to form spherical or conical-surface type structure in the middle of the cover plate.
The upper surface of the blind flange and cover plate is equipped with handle.
Having the beneficial effect that acquired by the utility model：The cover plate of the manhole is concordant with shell of dust remover, opens facility, no
Dust stratification, at the same avoid moisture is high, under grey glutinous serious conditions, the ash of bonding is by people's hole plug so as to cause the manhole cannot to open
The drawbacks of opening.Cover plate is each independent respectively with blind flange, and heat-barrier material can be arranged as required between them.Cover plate and cylinder
Gap is left between section, connection ring flat-plate, facility is opened.Cover plate lower surface is arranged as required to Wear-resistant heat insulation layer liner, can be set
With shell of dust remover identical liner, wear-resisting and heat-insulated effect is played.
Brief description of the drawings
Fig. 1 is generalized section of the present utility model.
In figure：1- shell rings, 2- flanges, 3- pads, 4- blind flanges, 5- cover plates, 6- connections ring flat-plate, 7- sealing rings.
Specific embodiment
In order to more fully understand the utility model, the technical solution of the utility model is done with reference to embodiment and accompanying drawing
Further instruction（As shown in Figure 1）.
A kind of double-deck accumulatingdust manhole, it includes shell ring 1, flange 2, blind flange 4, cover plate 5 and connection ring flat-plate 6；The cylinder
The upper end in the outside of section 1 is welded with flange 2, and mounting flange lid 4 on flange 2 is provided between the flange 2 and blind flange 4（Sealing is used
's）It is fastenedly connected by bolt or bearing pin between pad 3, and flange 2 and blind flange 4；The inwall of the shell ring 1 is welded with company
Ring flat-plate 6 is connect, cover plate 5 is installed on connection ring flat-plate 6,（After installation）Cover plate 5 is concordant with shell of dust remover, the cover plate 5 be connected
It is provided between ring flat-plate 6 between sealing ring 7, and cover plate 5 and connection ring flat-plate 6 and is fastenedly connected by bolt or bearing pin.
Heat-barrier material is filled between the blind flange 4 and cover plate 5.
The lower surface of the cover plate 5 is provided with（With shell of dust remover inwall identical）Wear-resistant heat insulation layer liner.
Raise up to form spherical or conical-surface type structure in the middle of the cover plate 5（The periphery of cover plate 5 still with deduster shell
Body is concordant）.
The upper surface of the blind flange 4 and cover plate 5 is equipped with（" n " font）Handle.
A kind of application method of double-deck accumulatingdust manhole：By dismantling bolt or bearing pin on blind flange 4, flange is first opened
Lid 4；Then the bolt or bearing pin on dismounting cover plate 5, open cover plate 5, open manhole.
It is described above be only Application Example of the present utility model, can not be limited with this certainly the utility model it
Interest field, therefore the equivalence changes made according to present utility model application the scope of the claims, still belong to protection domain of the present utility model.
