Problems solved by technology

Although the structure of the powder spraying room is not complicated, because it is a non-standard equipment, there are many changing factors that need to be adjusted according to the external dimensions of the workpiece during design. A little carelessness will result in poor recovery effects and powder spillage.
[0003] In the existing technology, the design of the powder spraying room is mainly based on field experience, and this method often leads to design results that are not optimal, or even fail, and this method is not conducive to the development and application of new products

Embodiment Construction

[0018] A kind of method of the present invention is based on fluent software to the method for optimal design of powder spraying chamber, comprises the following steps:

[0019] 1) According to the hanging size of the workpiece and the layout of the spray gun, determine the overall size and inlet and outlet dimensions of the powder spraying room, determine the recovery port and operating port size of the powder spraying room according to the recycling needs and operating requirements, and determine the size of the powder spraying room according to the electrostatic powder coating production line. Determine its specific location based on on-site conditions and experience, and parameterize the basic size of the spray booth and the location of each inlet and outlet;

[0020] 2) Using the good interactivity of VB, establish a parameterized input interface for the powder spraying room model, where the input parameters include: the basic dimensions of the powder spraying room, the si...

Abstract

The invention provides a method for optimally designing a powder spray room based on fluent software, which comprises the following steps of: calculating the basic dimensions of the powder spray room according to field conditions, preliminarily determining the position of each input and outlet according to experience, and parameterizing the position; compiling the parametric input interface of the powder spray room by using VB (Visual Basic), inputting the parameters obtained in the calculation, and further generating APDL (ANSYS Parameter Design Language) codes; calling the batch program of ANSYS by using VB and generating APDL codes to perform mesh generation on a created powder spray room model, and generating a CBD format file; reading the CBD format file by the Fluent software, and simulating the model in an analogue way; and modifying the parameter model according to the analogue simulation result, and repeating the above steps until an optimal result is obtained. The method has the advantages that because the powder spray room is simulated in an analogue way by using the technical scheme, each parameter of the powder spray room is adjusted according to the simulation result, and the analogue simulation is repeated for many times until one optimal design of the powder spray room is obtained.

Description

technical field [0001] The invention relates to an optimal design method for a powder spraying booth in the painting industry, specifically a method for simulating the powder spraying booth by using fluent software and realizing the optimal design of its structure through joint application with various software. Background technique [0002] The electrostatic powder coating system consists of a powder spraying room, recovery device, exhaust fan, discharge device, screen filter, coating machine, spray gun, reciprocating machine, etc., and the design of the powder spraying room is the most important part of the coating system design heavy. Although the structure of the powder spraying room is not complicated, because it is a non-standard equipment, there are many changing factors that need to be adjusted according to the external dimensions of the workpiece during design. A little carelessness will result in poor recovery effects and powder spillage. [0003] In the prior art...
