Parametric solid-state wireframe modeling of a water treatment plant in a block-complete design

The process of creating a model of a water treatment plant in a block-complete design using the technology of parametric solid-state wireframe modeling with the help of the Autodesk Inventor Professional software product is considered. The water treatment plant being developed is based on technological schemes for treating underground waters from dissolved gases (radon, hydrogen sulfide, carbon dioxide) and dissolved forms of iron and manganese using aeration. The paper describes the procedure for creating a model, consisting of the following steps: preparation of design schemes (sketches) of the model, description of sketches using parameters, creation of a wireframe, testing of a wireframe model; preparation of a working model. The model has showed the ability to transform, i.e. to change dimensions when changing parameters. The error-free transformation of the model when changing parameters is ensured by the forked scheme of the wireframe and the binding of components in the assembly to the wireframe. The use of structural pairs makes it possible to quickly replace components in the assembly when changing the technological scheme of the installation. The multiplication of assembly units and the growth of interconnections between them has led to an increase in design parameters describing the geometry of the installation. At the stage of preparation for modeling, the missing assembly units of technological equipment, fittings and apparatus have been created, as well as libraries of parametric parts for the frame generator have been published. In this paper, a method for creating a model range when changing the technological scheme is proposed. As an example, two options for water treatment (deferrization and radon removal) have been considered. As a result, two models of installations with different weight and size characteristics have been obtained. The paper presents the technological scheme, the layout of technological equipment in plan in the form of a projection of overall dimensions, the assembly structure, and the isometric view of the installation.
