Abstract
The utility model belongs to pipeline configuration technical field, in particular to a kind of exhaust duct structure, described structure at least comprises first row airduct (1) and second row airduct (2), described first row airduct (1) and second row airduct (2) are hollow circuit cylinder pipeline, the external diameter of first row airduct (1) is the internal diameter of second row airduct (2), and first row airduct (1) part stretches into second row airduct (2) interior fit.The utility model has to be convenient to install, there is not the features such as deterioration phenomenon.
Description
Technical field
The utility model belongs to pipeline configuration technical field, particularly a kind of exhaust duct structure.
Background technique
In coating equipment, spraying coating line often has a lot of airduct to need to draw outside factory building, the every two joint airduct Flange joint of traditional exhaust duct, flange angle steel is welded, airduct at flange position flange, with airduct spot welding, and beat silica gel sealing, intermediate cryptographic sealing skin seals, and with sealed material (as rubber), not only cost is high, and easily aging.
CN201010102409.6, on August 3rd, 2011 applies for, the present invention relates to a kind of leakage-proof connecting structure of exhaust ducts, two exhaust duct joints are provided with an etch-proof elastic interface liner, by arranging the etch-proof elastic interface liner that can be close to the inwall of exhaust duct and flange at the flange connections of exhaust duct, thus prevent the seepage of waste gas, but wherein relate to annular recess, sealing compound is also needed to load in annular recess, during installation, program is complicated, and, flexible liner is generally rubber material, easily aging, also not easily find after aging.
Model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of exhaust duct structure being convenient to install, do not exist deterioration phenomenon.
To achieve these goals, the utility model is by the following technical solutions:
A kind of exhaust duct structure, described structure at least comprises first row airduct and second row airduct, described first row airduct and second row airduct are hollow circuit cylinder pipeline, and the external diameter of first row airduct is the internal diameter of second row airduct, and first row airduct part stretches into fit in second row airduct.
As preferably, described first row airduct and second row airduct are fixed by two angle steel.
More preferred, described two angle steel are fixedly connected with and connect specifically by bolt.
Or more preferred, described two angle steel weld with the outer surface of first row airduct and second row airduct respectively.
In sum, the beneficial effects of the utility model are:
1, exhaust duct at least comprises first row airduct and second row airduct, be hollow circuit cylinder pipeline, the external diameter of first row airduct is the internal diameter of second row airduct, namely the two bore is different, and first row airduct part stretches into fit in second row airduct, the two tight fit, water is utilized to reach the watertight effect by two exhaust duct jointings sealings due to the principle of flows by action of gravity, do not relate to easy aging material in whole equipment, there is not deterioration phenomenon, and installation replacing is got up more for convenience; On the other hand, first row airduct part stretches into fit in second row airduct, and fit part is two-layer exhaust duct thickness, and particularly inner exhaust duct receives maximum protection, can also improve working life.
2, further, it is for the ease of fixing two exhaust ducts that the utility model arranges angle steel, two angle steel weld with the outer surface of first row airduct and second row airduct respectively, and be positioned near two exhaust duct jointing places and work in coordination, bolt is utilized to be fixed by two angle steel, thus first row airduct and second row airduct are fixed, the stability of exhaust duct is strengthened, by external force affects, Seepage does not occur.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged diagram of annexation between the utility model exhaust duct;
Description of symbols:
1-first row airduct; 2-second row airduct; 3-angle steel; 4-bolt.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described, therefore the utility model is not limited among described scope of embodiments.
embodiment 1
Composition graphs 1 and Fig. 2 are described:
Exhaust duct structure, at least comprise first row airduct 1 and second row airduct 2, described first row airduct 1 and second row airduct 2 are hollow circuit cylinder pipeline, and the external diameter of first row airduct 1 is the internal diameter of second row airduct 2, and the bottom fit of second row airduct 2 is stretched on the top of first row airduct 1; First row airduct 1 is fixed by two angle steel 3 with second row airduct 2, and described two angle steel 3 weld with the outer surface of first row airduct 1 and second row airduct 2 respectively; Described two angle steel 3 are fixedly connected with and connect specifically by bolt 4.
Claims (4)
