Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical industry, in particular to a tooling for controlling the installation accuracy of a cone limiting plate. Background Art

[0002] The extraction tower is a liquid-liquid mass transfer equipment commonly used in chemical industry, petroleum refining, environmental protection and other industrial sectors. The extractor used for continuous multiple extractions is a tower equipment called an extraction tower. The most important tower internals are composed of 5-7 groups of inner and outer cones, which are nested in a chain or even more.

[0003] The gap between the 8 limit plates evenly distributed on the circumference of the outer cone of the extraction tower and the inner cone is less than 1mm, and the gap is always less than 1mm within the range of 280mm of the inner cone's up and down reciprocating motion. The roundness requirement is high, and the installation requirements of the limit plates are high. At the same time, the outer cone is large in volume, thin in wall thickness, and poor in rigidity, which is easy to cause manufacturing deformation, thus affecting the manufacturing accuracy. For this reason, we propose a cone limit plate installation accuracy control tooling. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a cone limiting plate installation precision control tooling.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Preferably, lightening holes are provided at equal intervals in the middle of the outer ring plate.

[0008] The cone limit plate installation precision control tooling proposed in the utility model has the beneficial effect that the utility model can facilitate the installation of the limit plate and ensure the installation precision of the limit plate, and at the same time can effectively control the welding deformation of the outer cone during installation, greatly ensuring the qualified rate.

[0016] Reference Figure 1-3 The cone limit plate installation precision control tooling comprises a bottom ring plate 1, and four first channel steels 2 are fixedly installed on the upper surface of the bottom ring plate 1 at equal intervals. A middle ring plate 3 is fixedly installed on the top of the first channel steel 2. A second channel steel 4 corresponding to the first channel steel 2 is fixedly installed on the upper surface of the middle ring plate 3 at equal intervals. There are four first channel steels 2 and second channel steels 4, which can leave an effective space for the installation of the limit plate. An upper ring plate 5 is fixedly installed on the top of the second channel steel 4. An outer ring plate 6 is sleeved on the outer side of the upper ring plate 5. The outer ring plate 6 positions the top of the outer cone. The outer edge of the outer ring plate 6 is located at the inner top of the outer cone. The outer edge of the bottom ring plate 1 is located at the inner bottom of the outer cone. The bottom ring plate 1 positions the bottom end of the outer cone. Eight limit plates are welded at equal intervals on the inner lower part of the outer cone. One side of the limit plate conflicts with the bottom ring plate 1 and the middle ring plate 3, and the limit plate is positioned by the bottom ring plate 1 and the middle ring plate 3.

[0017] Lightening holes are provided at equal intervals in the middle of the outer ring plate 6. The provision of the lightening holes also facilitates the installation of the limit plate.

[0018] Working principle: When in use, place the outer cone on a horizontal working platform, place the tooling on the horizontal working platform, and at the same time, put the outer cone on the outside of the tooling to ensure that the upper and lower ports of the outer cone are parallel to the working platform, the axis of the outer cone is concentric with the axis of the tooling, and the upper and lower port surfaces of the outer cone are perpendicular to the axis of the tooling. The bottom ring plate 1 and the outer ring plate 6 realize the positioning of the lower and upper ports of the outer cone, draw the limit plate installation line on the side of the middle ring plate 3, assemble the limit plate according to the installation line, and spot weld the limit plate and the middle ring plate 3, and then weld the limit plate to the outer cone. After welding is completed, remove the tooling.
