The skirt is the main bearing part of various containers, such as applied to equipment such as pressure vessels, heat exchangers and the like. For a vertically installed heat exchanger, the skirt is mostly located at the bottom of the heat exchanger, the skirt usually includes a cylinder, a cover plate fixed on the outer wall of the cylinder, and a bottom plate located at the bottom of the cylinder, the bottom plate is used for being placed on a foundation, through holes for mounting bolts (also called anchor bolts) on the foundation to pass through are opened on the bottom plate and the cover plate, after the skirt is installed on the foundation, a container to be installed (such as a shell of the heat exchanger) is placed on the cylinder again and welded into a whole; or the container to be contained and the cylinder are connected by adopting a tongue-and-groove, for example, a skirt structure is disclosed in the document with the Chinese authorization publication number of CN 207012957U.
In the skirt structure of the existing heat exchanger, foundation bolts for connection are arranged outside a cylinder body of the skirt. Because the wound tube type heat exchanger has incomparable advantages compared with other types of heat exchangers, the existing wound tube type heat exchanger is more and more commonly applied to petrochemical equipment, and in some modification projects, the wound tube type heat exchanger replaces the original imported plate type heat exchanger. However, the skirt of the imported plate heat exchanger is generally small and is inconsistent with the connecting size of the skirt which is conventional in China, so that the newly-installed wound tube heat exchanger has matching deviation in installation. Therefore, when the transformation is carried out, the old foundation can not be utilized, so that the transformation cost is increased, the construction period is prolonged, the competitiveness and the further popularization and application of the wound tube type heat exchanger are influenced to a certain extent, and the localization of the core heat exchanger of the transformation device is subjected to bottleneck. Therefore, how to solve the problem of quick installation in the transformation project of the wound tube type heat exchanger is urgently needed to be solved.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to prior art's current situation, provide a skirt structure of winding tube heat exchanger bottom to be favorable to the wide use of winding tube heat exchanger in the equipment transformation.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a skirt structure of winding pipe heat exchanger bottom, is including the barrel, fix apron on the barrel outer wall and the bottom plate that is located the barrel bottom, open a plurality of mounting holes that supply rag bolt to pass, its characterized in that on apron and the bottom plate respectively correspondingly: a plurality of windows corresponding to the foundation bolts in number are formed in the side wall of the barrel at intervals along the circumferential direction, a plurality of platforms capable of extending into the corresponding windows extend inwards in the radial direction on the cover plate, and at least part of each mounting hole in the cover plate is located on the corresponding platform.
In order to further improve the strength of the skirt structure, sleeves corresponding to the mounting holes and through which the anchor bolts pass may be provided between the cover plate and the bottom plate.
Similarly, a plurality of rib plates distributed at intervals along the circumferential direction can be arranged between the cover plate and the bottom plate, and the upper end and the lower end of each rib plate are respectively connected with the cover plate and the bottom plate, so that the cover plate is supported on the bottom plate more stably.
In each of the above aspects, in order to facilitate the tightening operation of the anchor bolt by the constructor, the highest point of the inner edge of the window is higher than the top end of the installed anchor bolt.
In view of the possibility of the anchor bolts being located in aligned positions of the windows, the windows extend to the bottom of the barrel for ease of socket installation and anchor bolt penetration. And at this moment, the window is preferably designed into upper and lower section windows, and the lower section window is designed into a rectangle matched with the sleeve, so that the installation of the sleeve is not interfered, and the strength of the barrel is ensured.
Compared with the prior art, because the utility model discloses set up the window on the barrel lateral wall ingeniously to extend the platform that stretches into the window on the apron, consequently can combine the rag bolt's on-the-spot basic ground position with the help of this platform, make the inside skew of corresponding mounting hole on apron and the bottom plate, thereby need not reform transform old basic ground, just can conveniently install winding tubular heat exchanger on original basic ground, thereby can make winding tubular heat exchanger can popularize and apply smoothly in reforming transform the project.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1 to 4, a preferred embodiment of the present invention is that the skirt structure of the bottom of the winding tube heat exchanger includes a cylinder 1, a cover plate 2 and a bottom plate 3 located at the bottom of the cylinder, wherein the upper end of the cylinder 1 is used to be fixed to the casing 7 of the winding tube heat exchanger (welded and fixed in the figure), the bottom of the cylinder 1 is placed on the bottom plate 3, and the sidewall of the cylinder 1 is provided with a through hole 11 for the pipe of the winding tube heat exchanger to enter. The bottom plate 3 is an annular structure and is placed on a foundation 8. The cover plate 2 is fixed on the outer wall of the cylinder 1, a plurality of mounting holes 6 for the foundation bolts 9 to pass through are correspondingly formed in the cover plate 2 and the bottom plate 3 respectively, the mounting holes are all in the prior art, in the embodiment, a plurality of windows 12 corresponding to the foundation bolts in number are formed in the side wall of the bottom of the cylinder 1 at intervals along the circumferential direction, a plurality of platforms 21 corresponding to the windows extend inwards in the radial direction of the cover plate 2, and at least parts of the mounting holes in the cover plate 2 are located on the corresponding platforms 21. I.e. the mounting holes in the cover plate 2 may be located entirely on the platform within the window 12; or one part of the mounting hole may be located in the window 12 and the other part of the mounting hole may be exposed out of the window 12, as shown in the figure, the mounting hole of the cover plate 2 is located at a position just aligned with the window 12.
In order to further increase the strength of the skirt structure, sleeves 4 are provided between the cover plate 2 and the bottom plate 3 corresponding to the mounting holes and through which anchor bolts 9 are inserted. Meanwhile, a plurality of rib plates 5 distributed at intervals along the circumferential direction can be arranged between the cover plate 2 and the bottom plate 3, and the upper end and the lower end of each rib plate 5 are respectively connected with the cover plate 2 and the bottom plate 3.
The highest point of the inner edge of the window 12 is preferably higher than the top end of the installed foundation bolt 9, so that the foundation bolt 9 can be conveniently fastened by constructors. Considering that the anchor bolts 9 may be located at positions where the windows 12 are aligned, as shown in the drawing, the windows 12 extend to the bottom of the barrel 1 in order not to interfere with the installation of the anchor bolts 9 and the sleeves 4, and considering the strength of the barrel 1, the windows 12 are designed as upper and lower sections penetrating each other, the upper section windows 121 are designed in a race track shape, and the lower section windows 122 are designed in a rectangular shape matching the sleeves. Of course, other shapes may be devised, such as a U-shaped configuration, as desired.
