Description
Technical field
The utility model relates to a kind of formula dust-protection type its expansion joint dredged, specifically a kind of be installed in medium upwards or with the pipeline that is tilted on the dust-protection type its expansion joint that uses, belong to the pipe joint field.
Background technique
Along with development and national economy, the industrial production of China has had significant progress, the environmental protection industry of China is in the development and the growth that continue, and the environmental protection industry industrial market of following China is also very wide, and only the demand of industrial dust such as cogeneration, waste incineration and generating electricity improvement is just very big.Its expansion joint was applied more and morely on the smoke wind pipe of industries such as building materials, electric power, metallurgy and relevant device in the last few years, needed to adapt to different environmental requirements such as noise elimination, shock insulation, dustproof, anticorrosion, fire-retardant, large compensation amount and energy-saving and emission-reduction.Its expansion joint that in the big pipeline of some velocity of medium height, dust loading, needs dust-protection type.In the abominable pipeline of these working conditions, the high temperature that its expansion joint is subjected to for a long time, the impact of high flow rate dust, high temperature very easily makes the inside lining sleeve distortion, the dust very easily inner chamber between inside lining sleeve and thermal-protective coating is piled up, accumulate over a long period, increasing when accumulating amount, make inside lining sleeve and thermal-protective coating push to covering, finally covering is extracted under pressing plate by force, whole expansion joint is destroyed.Before the utility model, the domestic dust-tight its expansion joint that designed, between thermal-protective coating and inside lining sleeve, Dust-proof bag is set, stopping up dust with Dust-proof bag invades to the inner chamber of expansion joint, but the distortion of inside lining sleeve is opened the space of accumulation to dust, and the dust of accumulation causes the compensation rate of expansion joint not reach the desired value of piping displacement, bring potential safety hazard for the operation of pipeline, shortened the working life of expansion joint.
Summary of the invention
The purpose of this utility model be to provide a kind of medium upwards or use on the pipeline that is tilted to the formula of dredging dust-protection type its expansion joint, the mode that adopts perforate to dredge dust solves the problem that dust is piled up, and improves the working life of its expansion joint.
The utility model in order to achieve the above object, a kind of formula dust-protection type its expansion joint of dredging is provided, comprise metal framework (10) by fixing flexible covering (3), guide shell and two corresponding settings of pressing plate (1) and bolt (2), guide shell is the bidirectional guide tube, a guide shell (7) is fixed on the framework, another is fixed on the end pipe for guide shell with holes (8), dust fall hole (9) is arranged on the guide shell with holes, rake fixing outer thermal-protective coating (4), inner insulating layer (5) and Dust-proof bag (6) are arranged in framework.
The utility model is dredged formula dust-protection type its expansion joint, has designed the bidirectional guide barrel structure, and guide shell (7) is fixed on the metal framework, and also design has guide shell with holes (8) to be fixed on the end pipe, and dust fall hole (9) is arranged on the guide shell with holes.When the medium that dust concentration is high in pipeline upwards flowed, a large amount of dust were blocked by guide shell with holes and Dust-proof bag (6), and dust is taken away with air-flow; After expansion joint is moving a period of time, because the small displacement distortion of guide shell with holes, skew produces the slit, the dust that gravitate falls after rise slowly begins to fall in the slit between lower end guide shell with holes and the inner insulating layer (5), because on the guide shell with holes the dust fall hole is arranged, the dust in the slit falls by the dust fall hole, takes away with the medium of high flow rate again, shown in arrow among Fig. 1, thereby avoided the accumulation of dust.When the pipeline blowing-out, dust is subjected to self gravitation effect free falling, drops on the guide shell with holes, falls from the timely white-out in dust fall hole, has avoided the dust accumulation, has improved expansion joint working life.The utility model utilizes the free falling of dust self gravitation, from dust fall hole white-out dust, has solved expansion joint internal cause dust pile and has manufactured into short problem in working life.
The utility model is dredged formula dust-protection type its expansion joint, and the described outer thermal-protective coating (4) that rake is fixed in framework is to make with glass fiber cloth parcel ceramic fiber blanket.Described inner insulating layer (5) is to adopt different fibre cloth parcel ceramic fiber blankets to make according to serviceability temperature, wrapping up ceramic fiber blanket in time below 200 ℃ with glass fiber cloth when temperature makes, make with asbestos cloth parcel ceramic fiber blanket in the time of 200～400 ℃, make with ceramic fiber cloth parcel ceramic fiber blanket more than 400 ℃.Described Dust-proof bag (6) is to make with Stainless Steel Cloth or ceramic fiber cloth parcel ceramic fiber blanket.It is of uneven density to adopt fixing inside and outside thermal-protective coating of rake and Dust-proof bag can prevent that ceramic fiber blanket installation backward shift, tenesmus from causing, and guarantees thermal-protective coating and the good function of use of Dust-proof bag.
The utility model is dredged formula dust-protection type its expansion joint and is had following advantage:
1, the utility model adopts design concept unlike the prior art, swiftly flowing dust in the expansion joint is not only adopted stifled mode, also adopt mode stifled and that white-out combines to solve expansion joint internal cause dust pile and manufacture into short problem in working life, the effect that reduces the dust accumulation is obvious.
2, the utility model adopts the design of bidirectional guide tube, designs the structure that the dust fall hole is arranged on a guide shell therein, and the dust when blowing-out in the pipeline is fallen by the self gravitation effect, falls timely white-out by the dust fall hole and falls, and has avoided the accumulation of dust.The utility model scientific structure, make simple, cost is low, easy for installation, environmental protection, long service life and good in economic efficiency.
Description of drawings
Below the utility model is described in further detail with accompanying drawing:
Fig. 1 dredges formula dust-protection type its expansion joint structural representation for the utility model.
Fig. 2 is the A-A view of Fig. 1.
