Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical industry, in particular to a large-scale high-precision external circular supporting tooling. Background Art

[0002] An extraction tower is a liquid-liquid mass transfer device commonly used in industrial sectors such as chemical industry, petroleum refining, and environmental protection. The extractor used for continuous multiple extractions is a tower-type device called an extraction tower. The main internal components of this device are a structure in which multiple large and small cones are mutually inlaid. Among them, the wall thickness of the large cone of the internal component is thin, the shape is large, and it is a welded structure with the shell. Therefore, the roundness of the shell directly affects the installation accuracy between the internal limiting plates of the large cone of the internal component. Therefore, in order to improve the roundness of the shell after production, and at the same time, when installing the large cone of the internal component inside the shell, the roundness of the shell also needs to be strictly controlled. To solve the above situation, we propose a large-scale high-precision external circular supporting tooling. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a large-scale high-precision external circular supporting tooling.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] Design a large-scale high-precision external circular supporting tooling, including a cylinder and two arc-shaped plates. The two arc-shaped plates form an annular plate. The cylinder is located in the middle of the annular plate and is fixedly welded between the cylinder and the arc-shaped plates. Both ends of the two arc-shaped plates are fixedly welded with connecting plates. The distance between the two corresponding connecting plates is 30 mm. A partition plate is placed between the two corresponding connecting plates. A bolt-nut fastener is installed through the two corresponding connecting plates.

[0006] Preferably, the partition plate is located on the side away from the cylinder.

[0007] Preferably, a through hole with the same outer diameter as the extraction tower shell is opened in the middle of the cylinder, and the cylinder is cut in half along the opposite surfaces of the two connecting plates.

[0008] The beneficial effects of the large-scale high-precision external circular supporting tooling proposed by the utility model are as follows: By using this tooling, the roundness of the shell during assembly can be guaranteed, and the roundness of the shell can also be ensured when installing the large cone of the internal component of the tower. It is convenient to use and simple to operate.

[0009] Of course, when implementing any product of the utility model, it is not necessarily required to achieve all the above advantages simultaneously. Brief Description of the Drawings
