Abstract
The utility model discloses an inner tube fixed knot constructs for sleeve chimney, this sleeve chimney comprise inner tube and urceolus that interior outer spacer sleeve was established, the inner wall of urceolus is equipped with rather than vertically load-bearing platform, the lower port of inner tube is equipped with the flange with the inner tube with the material to with the lower port welding of inner tube, the flange is parallel with load-bearing platform to through flange bolt. The fixing structure is welded and fixed in advance, and is bolted and installed on site, so that the fixing structure is more convenient and ensures the quality compared with the traditional welding and installation in a narrow space on site; secondly, this fixed knot constructs can all carry out welded fastening to the inside and outside of inner tube, and has solved the different problem of welding department material, and welding quality is more reliable.
Description
Technical Field
The utility model belongs to the technical field of the chimney package assembly and specifically relates to an inner tube fixed knot constructs for sleeve chimney is related to.
Background
Since the advent of sleeve type steel chimneys, the cost performance is high due to the structural advantages, so the sleeve type steel chimneys are popular in small and medium-sized categories, and the application range of the sleeve type steel chimneys in enterprises such as incineration, chemical engineering and the like is wider and wider. However, the fixing process of the lower port of the inner cylinder has a great disadvantage that a bearing platform is usually directly arranged on the inner wall of the outer cylinder and then directly welded and formed with the lower port of the inner cylinder, and the assembling and connecting process has the following defects: 1. the strengthening process treatment of the stress concentration part has the following limitations: the direct welding on site can only be limited to the inner side of the inner cylinder, and the outer side of the inner cylinder cannot be implemented; 2. influence of material difference on field welding operation: most of the inner cylinder is made of corrosion-resistant colored thin-wall materials, the bearing platform is made of carbon steel and is thick, the field direct welding process is unreasonable, and the welding quality and strength are difficult to guarantee; 3. influence of the structure on the field welding operation: in addition to the difference in material quality, direct tailor-welding with a great thickness difference is also a great contraindication for on-site welding operation, and the requirement of the specification cannot be satisfied; 4. environmental impact on field welding operations: firstly, the field operation space is small, and secondly, the operation point is not on the ground, so that the welding quality can not be ensured by a good welder.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: in order to overcome the deficiency of the background art, the utility model discloses an inner tube fixed knot constructs for sleeve chimney.
The technical scheme is as follows: the utility model discloses an inner tube fixed knot constructs for sleeve chimney, this sleeve chimney comprise inner tube and urceolus that interior outer spacer sleeve was established, the inner wall of urceolus is equipped with rather than vertically load-bearing platform, the lower port of inner tube is equipped with the flange with the inner tube with the material to with the lower port welding of inner tube, the flange is parallel with load-bearing platform to through flange bolt.
Therefore, when the flange is installed, the flange and the inner cylinder can be fixed in advance, and then the flange and the inner cylinder are directly bolted and fixed when the inner cylinder and the outer cylinder are installed without welding on site.
Furthermore, the junction of inner tube and flange is equipped with rather than the first strengthening rib of the same material, the first strengthening rib is with the upper surface welding of one side of port and flange under the inner tube.
Furthermore, the inner side and the outer side of the lower port of the inner cylinder, which are in contact with the flange, are fixed by welding. If the traditional process is adopted for field welding installation, welding can be carried out only on the outer side of contact, and double-side welding fixation cannot be carried out.
Furthermore, a second reinforcing rib is arranged below the bearing platform and is welded and fixed with the bearing platform and the inner wall of the outer barrel.
Has the advantages that: compared with the prior art, the utility model has the advantages that: the fixing structure is welded and fixed in advance, and is bolted and installed on site, so that the fixing structure is more convenient and ensures the quality compared with the traditional welding and installation in a narrow space on site; secondly, this fixed knot constructs can all carry out welded fastening to the inside and outside of inner tube, and has solved the different problem of welding department material, and welding quality is more reliable.
Drawings
FIG. 1 is a schematic structural view of a sleeve chimney according to the present invention;
fig. 2 is an enlarged view of the inner cylinder fixing structure of the present invention.
Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.
As shown in fig. 1 and 2, the inner tube fixing structure for the sleeve chimney is composed of an inner tube 1 and an outer tube 2 sleeved at an inner and an outer interval, the inner wall of the outer tube 2 is provided with a bearing platform 3 perpendicular to the inner wall, the bearing platform 3 is arranged on the inner wall of the outer tube 2 for a circle to form an annular platform, a plurality of second reinforcing ribs 7 are arranged below the bearing platform 3 and are welded and fixed with the bearing platform 3 and the inner wall of the outer tube 2 to support the inner tube 1 and the bearing platform 3, the lower port of the inner tube 1 is provided with a flange 4 made of the same material as the inner tube 1, the inner side and the outer side of the lower port of the inner tube 1 contacting with the flange 4 are fixed by welding, the joint of the inner tube 1 and the flange 4 is provided with a first reinforcing rib 6 made of the same material, the first reinforcing rib 6 is welded with one side of the lower port of the inner tube 1 and the upper surface, the flange 4 is parallel to the load-bearing platform 3 and is bolted by means of flange bolts 5.
This fixed knot constructs when the construction, can carry out prefabricated mounting flange 4 with inner tube 1, adopts also to guarantee welded quality with the material flange, and the notice prefabricated in-process can all weld the inside and outside of inner tube 1 again, and fixed rear structure is more reliable, and the prefabricated back directly carries out the bolt with flange 4 on the inner tube 1 and load-bearing platform 3 again, owing to be under construction in the narrow and small space again, and the bolt is more convenient and safety than the welding.
