Parameterization of the flow controller to reduce the consumption of disinfectant in the washing of garrafones

Abstract

The process of washing bottles of 20 liters based on systems with control designs, allows to improve the consumption of the disinfectant by determining an estimated amount for each bottle in an average time, this is given by the execution carried out in a structure designed for two bottles , where they rest on two supports previously built by 3D printing system that is ideal for this process since they do not exist in the market, the location of the bottle will be 90 ° in the downward direction subject by friction that prevents it from being expelled by the strength of the flow, the process is manipulated by physical action buttons or digital buttons designed in a graphic interface (HMI), obtaining the necessary flow for the washing process requires an identification, that is, the analytical model, which will be carried out in the pumping stage of the disinfectant, resulting in an equation called transfer function, this i it replicates a data reading that we will obtain with a flow sensor, which will allow us to extract a database for the identification process obtained through programming in the TIA Portal software, this flow information record will be processed in the Matlab platform which is what will allow us to determine this function, by obtaining this equation we can design the controller in the same plant with which we can program the controller in TIA Portal with the values ​​obtained.
