Abstract
The utility model relates to a seal reinforcing apparatus for dry-type dust removal ash conveying pipeline, including last joint sealing, lower joint sealing, closing cap, go up the joint sealing and close the knot at ash conveying pipeline and through the bolt fastening with lower joint sealing, go up the joint sealing top and be equipped with and put in the mouth, go up the joint sealing top and pass through bolt fixedly connected with closing cap, go up the joint sealing and be filled with fine sand in the cavity that the joint sealing formed down. The advantages are that: the encapsulating and reinforcing device for the dry dust removal and ash conveying pipeline increases the thickness of easily-worn parts such as a pipeline flange and the like by utilizing a cavity filling technology, and achieves the purpose of delaying wear. And fine sand is injected into the upper sealing box and the lower sealing box, so that the leakage of dust can be effectively prevented and prevented, and the later replacement and maintenance are not influenced. Whole device adopts the components of a whole that can function independently structure to by bolted connection, when can make things convenient for dismouting, reuse, do benefit to the maintenance, facilitate for subsequent overhaul greatly.
Description
Technical field
The utility model is related to a kind of encapsulating bracing means for dry dust removal ash conveying pipe.
Background technology
Blast furnace dry type (cloth bag) dust pelletizing system ash conveying pipe go into operation since due to serious wear, often in babinet to big ash cellar
Leakage is ground during defeated ash manipulation, gas ash is caused to leak, nitrogen leaks, coal gas leaks, not only surrounding enviroment are impacted, nitrogen
The leakage of gas and coal gas forms security risk to the personal safety of post staff.By observing, counting, the leakage in mill fistulae road
Point is concentrated mainly on pipe flange section (flange gasket and flange root), and gas ash scouring force is maximum, is easiest to mill leakage.Once hair
Existing pipeline leakage, conventional method are off defeated ash manipulation, and with nitrogen displacement, if pipeline has leak source progress soldering, flange
Place has leak source then to need dismounting and change flange.If leak source frequently leaks whether great or small, it is required for frequently carrying out aforesaid operations,
Influence normal production.
The content of the invention
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of for dry dust removal ash conveying pipe
Bracing means is encapsulated, slows down and prevent ash pipeline line pernicious gas and dust leakage caused by abrasion, mitigates repair apparatus work
It measures.
To achieve the above object, the utility model is achieved through the following technical solutions：
A kind of encapsulating bracing means for dry dust removal ash conveying pipe, including upper joint sealing, lower joint sealing, capping, upper joint sealing
It is closely closed with lower joint sealing and is buckled in ash conveying pipe and is bolted, dispensing port is equipped at the top of upper joint sealing, is led at the top of upper joint sealing
It crosses bolt and is fixedly connected with capping, fine sand is filled in the cavity that upper joint sealing is formed with lower joint sealing.
Sealing ring is equipped between the upper joint sealing, lower joint sealing and ash conveying pipe.
Strip of paper used for sealing is equipped between the upper joint sealing and lower joint sealing.
Compared with prior art, the beneficial effects of the utility model are：
The easily mill such as cavity filling technique, increase pipe flange is utilized for the encapsulating bracing means of dry dust removal ash conveying pipe
The thickness at position is damaged, plays the purpose for delaying abrasion.Upward joint sealing and injection fine sand in lower joint sealing, can effectively preventing dedusting
Ash leakage, and later replacement, maintenance are not influenced.Whole device uses Split type structure, and by being bolted, conveniently detachable,
While recycling, beneficial to maintenance, facility is provided for subsequent general overhaul.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the working state figure of the utility model.
In figure：Joint sealing 3- covers 4- sealing ring 5- strip of paper used for sealing 6- ash conveying pipes on joint sealing 2- under 1-.
Specific embodiment
The utility model is described in detail with reference to Figure of description, it should be noted that the utility model
Implementation is not limited to following embodiment.
See Fig. 1, a kind of encapsulating bracing means for dry dust removal ash conveying pipe, including upper joint sealing 2, lower joint sealing 1, capping
3, upper joint sealing 2 closely closes with lower joint sealing 1 and is buckled in ash conveying pipe 6 and is bolted, and upper 2 top of joint sealing is equipped with dispensing port,
Upper 2 top of joint sealing has been bolted to connection capping 3, and fine sand is filled in the cavity that upper joint sealing 2 is formed with lower joint sealing 1, should
Cavity can encapsulate 6 body of ash conveying pipe, and also the flange on ash conveying pipe 6 can be encapsulated.
See Fig. 2, wherein, sealing ring 4 is equipped between upper joint sealing 2, lower joint sealing 1 and ash conveying pipe 6, avoids leakage husky.Upper joint sealing 2
Strip of paper used for sealing 5 is equipped between lower joint sealing 1, after preventing that joint sealing 2,1 closes button up and down, long-term corrosion causes leakage husky, while also functions to isolation
Effect, convenient joint sealing 2,1 up and down dismantles.In addition to using sealing ring 4 and strip of paper used for sealing 5, foaming agent also can be used and be packaged, prevent
Leak-stopping is husky.
Fig. 2 is seen, by taking the flange encapsulating of ash conveying pipe 6 as an example：Make square upper joint sealing 2, the lower joint sealing that flange can be wrapped up
1, and dispensing port is opened in upper joint sealing 2, the semicircle orifice to match with ash conveying pipe 6 is opened in joint sealing both sides, to avoid damage to ash conveying pipe 6
And anti-leak-stopping is husky, and sealing ring 4 can be set on semicircle orifice hole wall.Upper joint sealing 2, the conjunction of lower joint sealing 1 are buckled on the flange of leak source,
Blending bolt is fixed, and injects fine sand to dispensing port, finally with 3 closure dispensing port of capping.Fine sand selects the following fine sand of 50 mesh.
9 months No leakages are continuously run using the ash conveying pipe 6 of the present apparatus, are substantially reduced caused by pipeline mill leakage
Dust, nitrogen, coal gas leak the security risk to be formed, greatly reduce maintenance intensity.
