Abstract
The invention discloses a kind of device for adjusting chimney internal cylinder concentricity, the technical scheme of use is：Multilayer floor is set in biside plate corresponding space, mandrel passes through from multilayer floor, and the centre of biside plate is additionally provided with notch.Using the tear that is flexible coupling present invention completely avoids the Concentricity tolerance because of the upper and lower inner tube installation of chimney is too big, is caused, flue gas, the generation of harm safety in production hidden danger are revealed.
Description
Technical field
The present invention relates to a kind of device for adjusting chimney internal cylinder concentricity.
Background technology
At present, the unit in charge of construction of mounting industrial chimney, when lifting the suspension inner cylinder of chimney, it will usually from stiffener plate
It is fixedly welded on after upper and lower inner cylinder to install and is flexible coupling, is then lifted out lower inner cylinder, after lifting in place, cuts off stiffener plate, reinforcement
After plate is cut off, inner cylinder is in free state, can meet the technical requirements being flexible coupling, but this is that can reach under individual cases
Technical requirements, after being removed in most instances due to stiffener plate, the error of release and the lifting of inner cylinder welding interior stress, hold very much
Easily make upper and lower inner cylinder eccentric, cause the distortion that is flexible coupling, as deviation is larger, more easily causes the tear being flexible coupling, cause flue gas to be let out
Dew, hidden danger is brought to safe operation.
The content of the invention
It is an object of the invention to provide a kind of simple in construction easy to use, upper and lower inner tube installation is complete be flexible coupling after do not have to tear open
Remove, and can reaches the device of the adjustment chimney internal cylinder concentricity for the technical requirements that are flexible coupling.
The purpose of the present invention is achieved through the following technical solutions：The corresponding space of biside plate sets multilayer floor,
Mandrel passes through from multilayer floor, and the centre of biside plate is additionally provided with notch.
The present invention has simple in construction, free removal, moreover it is possible to the concentricity of upper and lower inner cylinder is controlled, being flexible coupling to be torn,
Flue gas will not be revealed, the safe operation of equipment can be ensured.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is Fig. 1 A-A views；
Fig. 3 is Fig. 1 B-B views；
Fig. 4 is Fig. 1 C-C views.
In figure：Side plate 1, floor 2, mandrel 3, notch 7.
Embodiment
From Fig. 1-4：The present invention sets four layers of floor 2 in the corresponding space of biside plate 1, and mandrel 3 is from four layers of floor 2
In pass through, the centre of biside plate 1 is additionally provided with notch 7.
Using the present invention, four or eight positive upper and lower ends of the invention are welded on the flange of upper and lower inner cylinder nearby,
The flange of upper and lower inner cylinder is seated in notch 7, lifts upper and lower inner cylinder to appropriate position, then biside plate 1 in recessed
The part side plate cutting lacked between 7 is removed.Due to having certain circumferential clearance between mandrel 3 and four layers of floor 2, lifting can be accommodated
When lateral error.Again because mandrel 3 pins down upper and lower inner cylinder, lower inner cylinder is set to keep concentricity in the scope of license with upper inner cylinder
It is interior, avoid lower inner cylinder and upper inner cylinder and tear and be flexible coupling because concentricity too big deviation dislocation occurs, flue gas is leaked, to peace
Full production brings hidden danger.Due also to the center section of biside plate 1 of the present invention has been removed, it can absorb when above inner cylinder is rationally sagging
Error, not can be appreciated that and do not remove stiffener plate in the prior art, when have stiffener plate bend deformation state.
