Abstract
Description
Technical Field
[0001] This utility model belongs to the field of separation tower technology, specifically relating to a tower body connection structure of an air separation tower. Background Technology
[0002] A gas separation tower is a chemical engineering term published by the National Committee for Terminology in Science and Technology in 2019. It refers to cryogenic equipment that separates single-component gaseous and liquid products from multi-component gases. Its applications cover air separation, natural gas processing, coke oven gas separation, water gas purification, synthetic ammonia off-gas treatment, and pyrolysis gas separation. The design of this equipment involves detailed drawings, main structural diagrams, and general layout drawings.
[0003] The existing tower body connection structure of air separators still has some defects. In most cases, the tower body needs to be kept aligned during the connection process to install the fixing bolts. However, the tower body is prone to misalignment during the installation of the fixing bolts, making it difficult to install the fixing bolts later. Therefore, we propose a tower body connection structure for air separators. Utility Model Content
[0004] The purpose of this utility model is to provide a tower body connection structure for an air separator, so as to solve the problem mentioned in the background art that the tower body connection is prone to misalignment, which makes it difficult to install subsequent fixing bolts.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a tower body connection structure for an air separator, comprising a first connecting flange, a second connecting flange on the top of the first connecting flange, a connecting block fixedly connected to the surface of the second connecting flange, a limiting spring inside the connecting block, a limiting block on one side of the limiting spring, a connecting frame fixedly connected to the surface of the first connecting flange, a limiting hole inside the connecting frame, and a connecting rod between the first connecting flange and the second connecting flange.
[0006] Preferably, the connecting rod has external threads at both ends and a first fixing nut at the top.
[0007] Preferably, the bottom of the connecting rod is provided with a second fixing nut, and the second fixing nut is threadedly connected to the external thread.
[0008] Preferably, the first connecting flange has a first through hole inside, and the second connecting flange has a second through hole inside.
[0009] Preferably, the bottom of the first connecting flange is provided with a lower tower cylinder, and the lower tower cylinder and the first connecting flange are fixedly connected.
[0010] Preferably, the top of the second connecting flange is provided with an upper tower, and the upper tower is fixedly connected to the second connecting flange.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. A second connecting flange is provided on the top of the first connecting flange. The second connecting flange drives the connecting block into the connecting frame of the first connecting flange. The limiting spring and the limiting block limit the height of the connecting block and the connecting frame, realizing the alignment of the first connecting flange and the second connecting flange of the air separator tower body connection structure. This improves the convenience of installing and fixing bolts after the air separator tower body connection structure is aligned.
[0013] 2. By providing external threads at both ends of the connecting rod, and installing a first fixing nut and a second fixing nut at each end of the connecting rod, the tower body connection structure of the air separator is reinforced, thereby improving the stability of the tower body connection structure installation and fixation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-5 This utility model provides a technical solution: a tower body connection structure for an air separator, including a first connecting flange 1, a second connecting flange 2 on the top of the first connecting flange 1, a connecting block 3 fixedly connected to the surface of the second connecting flange 2, a limiting spring 4 inside the connecting block 3, a limiting block 5 on one side of the limiting spring 4, a connecting frame 6 fixedly connected to the surface of the first connecting flange 1, a limiting hole 7 inside the connecting frame 6, and a connecting rod 8 between the first connecting flange 1 and the second connecting flange 2. The tower body is connected and fixed by the mating of the first connecting flange 1 and the second connecting flange 2. The connecting block 3 enters the connecting frame 6, causing the limiting block 5 to compress the limiting spring 4. The limiting spring 4 causes the limiting block 5 to retract inside the connecting frame 6. When it moves to the limiting hole 7, the limiting spring 4 returns to its original position, causing the limiting block 5 to enter the limiting hole 7, thus aligning the first connecting flange 1 and the second connecting flange 2.
[0022] Specifically, the two ends of the connecting rod 8 are provided with external threads 9, and the top of the connecting rod 8 is provided with a first fixing nut 10, which is used to install and fix one end of the connecting rod 8.
[0023] Specifically, the bottom of the connecting rod 8 is provided with a second fixing nut 11, which is threadedly connected to the external thread 9. The other end of the connecting rod 8 is installed and fixed by the second fixing nut 11.
[0024] Specifically, the first connecting flange 1 has a first through hole 12 inside, and the second connecting flange 2 has a second through hole 13 inside, through which the connecting rod 8 is installed.
[0025] Specifically, the bottom of the first connecting flange 1 is provided with a lower tower cylinder 15, which is fixedly connected to the first connecting flange 1, and forms the tower body through the lower tower cylinder 15.
[0026] Specifically, the top of the second connecting flange 2 is provided with an upper tower 14, which is fixedly connected to the second connecting flange 2, and the tower body is formed by the upper tower 14.
[0027] In this embodiment, during use, the upper tower 14 is lifted so that its second connecting flange 2 is aligned with the first connecting flange 1 for installation, and its connecting block 3 is aligned with the connecting frame 6 for installation. The limiting block 5 compresses the limiting spring 4, and the limiting spring 4 causes the limiting block 5 to retract inside the connecting frame 6. When it moves to the limiting hole 7, the limiting spring 4 returns to its original state, so that the limiting block 5 enters the limiting hole 7, aligning the first connecting flange 1 and the second connecting flange 2. Then, the connecting rod 8 is inserted, and the two ends of the connecting rod 8 are threaded and fixed. The first fixing nut 10 and the second fixing nut 11 are installed on the surface of the external thread 9.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
