Tower tray splicing structure

Abstract

This utility model discloses a tray splicing structure, including an interface on a first tray and a connecting plate on a second tray. One side of the first tray has a downwardly bent portion near the interface. One side of the second tray has an upwardly bent portion forming a vertical bend, followed by a horizontal bend forming a horizontal bend. One side of the connecting plate is fixedly connected to the horizontal bend via a vertical connecting portion. The connecting plate is horizontally positioned and, after being inserted into the interface, is located below the first tray. Compared to traditional bolt connections, the connection between the connecting plate and the interface in this tray splicing structure is simpler and faster to install, avoiding the risk of bolt loosening. The design of the downward bend and the vertical and horizontal bends enhances the structural strength and stability of the splice. The support structure between the bent plate and the downward bend, through the engagement of a snap-fit ​​portion and a snap-fit ​​groove, further improves the overall rigidity and reduces tray deformation.

Description

Technical Field

[0001] This utility model belongs to the field of tower tray technology, specifically relating to tower tray splicing structure. Background Technology

[0002] In industries such as chemical and petroleum, tower equipment is a key component in realizing gas-liquid and liquid-liquid mass transfer processes. The structural performance of its internal trays has a crucial impact on mass transfer efficiency and equipment operational stability. Tower trays typically need to be assembled by splicing together to form a large-area mass transfer working surface to meet the operational requirements of the tower equipment.

[0003] Currently, most existing tower tray splicing structures use simple bolt connections or welding methods. Bolt connections are not only cumbersome to install, requiring significant manpower and time for positioning and tightening, but also prone to loosening during long-term operation due to vibration, media erosion, and other factors. This can lead to gaps between trays, affecting mass transfer efficiency and potentially causing safety accidents. While welding provides a certain connection strength, the welding process generates significant thermal stress, which can easily deform the trays, affecting their flatness and levelness, thus reducing the mass transfer efficiency of the tower equipment. Furthermore, welded trays are extremely inconvenient to maintain and replace later, requiring considerable effort for cutting and re-welding.

[0004] Therefore, how to design a tower tray splicing structure that is firmly connected, easy to install, effectively avoids deformation, and is easy to maintain has become an urgent problem to be solved by those skilled in the art. Utility Model Content

One side of the first tray has a downward bending portion formed by bending downward, which is close to the interface. One side of the second tray is bent upward to form a vertical bending portion and then bent horizontally to form a horizontal bending portion. One side of the connector plate is fixedly connected to the horizontal bending portion through a vertical connecting portion. The connector plate is horizontally set and is located below the first tray after being inserted into the interface.

[0006] As a preferred embodiment of the above technical solution, the second tray plate is provided with a process port, and a bending plate formed by bending downward is provided on one side of the process port. The bending plate is parallel to the lower bending part and is set at the same height as the lower bending part.

[0007] As a preferred embodiment of the above technical solution, a support structure is provided between the bending plate and the lower bending part. The support structure includes two parallel support plates, the upper ends of the two support plates are fixedly connected, and the support plates are provided with outwardly arched fastening parts. The bending plate and the lower bending part are respectively provided with fastening grooves for the fastening parts to be engaged.

[0008] As a preferred embodiment of the above technical solution, the lower end of the support plate is bent outward horizontally to form a fixing part, and the fixing part is provided with a plurality of mounting holes.

[0009] As a preferred embodiment of the above technical solution, the second tray plate, the vertical bend, the horizontal bend, the vertical connecting part, and the plug plate are integrally formed; the first tray plate and the lower bend are integrally formed; and the two support plates and their fastening parts in the support structure are integrally formed.

[0010] The beneficial effects of this utility model are as follows: The splicing structure of the tray plate of this utility model, with its interlocking plate and interface, makes installation simpler and faster compared to traditional bolt connections, and avoids the risk of bolt loosening. The design of the lower bend and the vertical and horizontal bends enhances the structural strength and stability of the splice. The support structure between the bend plate and the lower bend, through the cooperation of the snap-fit ​​part and the snap-fit ​​groove, further improves the overall rigidity and reduces tray plate deformation.
