Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical industry, in particular to a tool for concentric and vertical positioning of a cone and a sleeve. 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 internal parts of the extraction tower include 5-6 sets of inner and outer cones that are interlocked and nested. The inner cone is large in size and thin in wall thickness, with poor rigidity, high requirements for manufacturing accuracy and form and position tolerances. When assembling the inner cone and the sleeve of the extraction tower, the concentricity, verticality and ellipticity of the inner cone and the sleeve of the extraction tower are high, which makes the assembly inconvenient. For this reason, we propose a concentric and vertical positioning tool for the cone and the sleeve. Utility Model Content
