Description

Technical Field

[0001] This utility model belongs to the field of air separation and distillation technology, and relates to an integrated steel-aluminum conversion positioning device for a small packed tower distributor. Background Technology

[0002] In the field of air separation distillation, the distributor in a packed column is a critical internal component, affecting not only the mass transfer efficiency of the packing but also its operational flexibility. Improper installation of the distributor can lead to uneven gas-liquid distribution, thereby affecting the mass transfer efficiency and reducing operational flexibility. Improper installation can also increase the frequency of equipment maintenance and raise operating costs.

[0003] In conventional designs, while packed towers are typically made of aluminum, the distributors within them are often made of stainless steel. This necessitates considering both the gas-liquid distribution efficiency of the distributor and its installation configuration within the non-ferrous distillation column. To ensure good distribution, the maximum size of the distributor is designed to be close to the inner diameter of the tower (generally controlled within 30mm), but this presents challenges for installation and fixation. Smaller distillation columns are typically installed horizontally; if the flatness and coaxiality of the distributor's mounting surface cannot be well controlled, the distillation efficiency of the column will be significantly reduced.

[0004] To address this issue, a steel-aluminum integrated positioning device for small packed tower distributors was designed to overcome the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a steel-aluminum conversion integrated positioning device for small packed tower distributors that has a simple and reasonable structure, is easy to install, takes into account the reference positioning of steel-aluminum conversion, and has a wide range of applications.

[0006] This utility model is achieved through the following technical solution: a steel-aluminum conversion integrated positioning device for a small packed tower distributor. Multiple positioning devices are provided and evenly arranged at the bottom of the distributor. The positioning device has a concave block structure, and the parallel bottom surface is connected to the distributor by bolts. An adjustment structure is provided between the distributor and the bottom surface. One side of the block structure is fixed to the inner wall of the cylinder by welding. A limit fixing hole is provided on this side, and a limit cam is arranged in the limit fixing hole. The limit cam and the bolt form a placement area for placing and locking the distributor.

[0007] As a preferred embodiment, the adjustment structure comprises guide rail grooves opened on both sides of the parallel bottom surface, and a guide rail that can slide within the rail. The distributor is installed on the guide rail, and bolts pass through the distributor to connect and fix it to the guide rail. The distance between the distributor and the inner wall of the cylinder is adjusted through the guide rail grooves.

[0008] Preferably, the limiting and fixing hole is a placement hole opened on the side of the parallel bottom surface near the cylinder, and has a square structure. A notch is also opened on the side of the square structure near the cylinder to facilitate the insertion of the limiting cam into the limiting and fixing hole.

[0009] Preferably, the limiting cam consists of an upper square limiting head, a long strip-shaped limiting body, and a block-shaped limiting block. The square limiting head is precisely embedded in the limiting fixing hole, and the limiting block and the limiting head are arranged at a 90-degree angle. Before installation, the limiting head is placed in the limiting fixing hole. During installation, the limiting body is lifted upward to disengage the limiting head from the limiting fixing hole. After reaching a certain distance, the limiting body is rotated 90° to weld the bottom limiting block perpendicularly to the lower support slider.

[0010] The beneficial effects of this utility model are as follows: This invention relates to an integrated steel-aluminum conversion positioning device for small packed tower distributors. It is easy to install and provides a reference positioning for steel-aluminum conversion, making it suitable for the installation of various types of distributors in packed towers. This invention enables free adjustment of the gap between the support slider and the inner wall of the packed tower cylinder. Rivets or bolts and limiting cams can be used as radial travel limits for the support slider. The limiting head at the bottom of the cam is perpendicular to the slider and welded, thereby locking the waist-shaped profile of the cam with the outer side of the distributor bottom ring and the arc-shaped profile of the cam with the inner wall of the cylinder, ensuring that the distributor is fixedly assembled on the cylinder axis and improving the overall stability after installation.

[0015] To enable those skilled in the art to more clearly understand the purpose, technical solution and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0017] The present invention will now be described in detail with reference to the accompanying drawings: Figure 1 As shown, a steel-aluminum conversion integrated positioning device for a small packed tower distributor is provided. Multiple positioning devices are evenly arranged at the bottom of the distributor 1. The positioning device is a concave block structure 2. The parallel bottom surface is connected to the distributor 1 by bolts. An adjustment structure 3 is provided between the distributor 1 and the bottom surface. One side of the block structure 2 is fixed to the inner wall of the cylinder 4 by welding. A limit fixing hole 5 is provided on this side. A limit cam 6 is arranged in the limit fixing hole 5. The limit cam 6 and the bolt form a placement area 7 for placing and locking the distributor 1.

[0018] The adjustment structure 3 consists of guide rail grooves 8 opened on both sides of the parallel bottom surface, and a guide rail 9 that can slide within the rail. The distributor 1 is installed on the guide rail 9, and bolts 15 pass through the distributor 1 to connect and fix it to the guide rail 9. The distance between the distributor 1 and the inner wall of the cylinder 1 is adjusted by the guide rail grooves 8.

[0019] The limiting and fixing hole 5 is a placement hole 10 opened on the side of the parallel bottom surface near the cylinder 4. It has a square structure and a notch 11 is also opened on the side of the square structure near the cylinder 4 to facilitate the insertion of the limiting cam 6 into the limiting and fixing hole 5.

[0020] The limiting cam 6 consists of a square limiting head 12, a long limiting body 13, and a block-shaped limiting block 14. The square limiting head 12 is embedded in the limiting fixing hole 5. The limiting block 14 is arranged at a 90-degree angle to the limiting head 12. Before installation, the limiting head 12 is placed in the limiting fixing hole 5. During installation, the limiting body 13 is lifted upward to disengage the limiting head 12 from the limiting fixing hole 5. After reaching a certain distance, it is rotated 90° to weld the bottom limiting block 14 vertically to the supporting slider 16 below.

[0021] The guide rails of this invention are machined from sheet metal parts. The guide rails are evenly distributed circumferentially on the underside of the distributor's bottom ring as needed, and each guide rail is fixed to the bottom ring with rivets or bolts, preserving axial freedom. The support slider functions as both a support and a slider, and is made of the same material as the cylinder. The support slider is located below the guide rails and has a sliding stroke to ensure radial freedom adjustment, allowing for free adjustment of the gap between the support slider and the inner wall of the packed tower cylinder. Rivets or bolts and positioning cams serve as radial travel limits for the support slider. The positioning cam is fitted within the support slider, preserving axial freedom. Its material can be the same as the cylinder. Simultaneously, it can be radially fixed by complex trajectory correction. Through multiple radial fixations along the circumference, the distributor is fixedly assembled onto the tower's axis.

[0022] For ease of understanding, the following is provided Figure 3-4 This is a diagram showing the overall usage state of the present invention after it is installed behind the distributor.

[0023] The overall working process of this utility model is as follows: After the main structure of the distributor is welded, the distributor is vertically hoisted. Utilizing the circumferential distribution of the liquid holes in the bottom ring of the distributor, four quadrant positioning points are symmetrically selected along the liquid holes (taking four points as an example). The guide rails are then fixed to the positioning holes in the liquid holes using rivets or bolts. Next, the support slider is inserted into the guide rail along its sliding stroke, and the limiting cam is inserted into the limiting groove from the outside of the support slider. This makes the distributor body, guide rails, support slider, and limiting cam movable components. The guide rails, support slider, and limiting cam can retract to the maximum external dimension of the distributor and are then hoisted together into the horizontal cylinder. Using container tooling to adjust coaxiality, ensuring the distributor assembly and cylinder are aligned, the four radial positions of the guide rail are checked. The telescopic support slider is then welded to the inner wall of the cylinder to ensure the distributor's installation level. After the support slider welding is completed, the limiting cam is pushed out axially to the limiting point. Finally, the limiting cam is symmetrically adjusted and rotated 90° in opposite directions to ensure the limiting head at the bottom of the cam is perpendicular to the slider and welded. This locks the cam waist profile with the outer side of the distributor bottom ring and the cam arc profile with the inner wall of the cylinder, ensuring the distributor is fixedly assembled on the cylinder axis.

[0024] The specific embodiments described herein are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
