Working principle of automatic local cleaning device

The machine can carry out automatic acid, alkali and disinfection cleaning procedures according to the cleaning time and cleaning sequence set by the user in the "parameter setting" column of the touch screen When the user presses the "prepare fresh acid for cleaning" button in the main menu bar of the touch screen, the system will automatically open the water inlet valve of the water tank, open the concentrated acid valve, and prepare the acid for cleaning according to a certain concentration proportion In the preparation process, the system automatically closes the water inlet valve according to the flow and opens the three-way valve to adjust it to the acid circulating cleaning state The buffer tank is used to store the acid solution Because it is used repeatedly, the concentrated acid consumed is very little When the user presses the "prepare fresh lye for cleaning" button in the main menu bar of the touch screen, the cleaning principle is the same as above When the user presses the "prepare fresh disinfectant for cleaning" button in the main menu bar of the touch screen, the cleaning principle is the same as above When the user presses the "circulating liquid cleaning" button in the main menu bar of the touch screen, the system will automatically circulate and clean the acid liquid, alkali liquid or disinfectant stored in the buffer tank This working condition is used when the user has used "prepare fresh acid for cleaning" or "prepare fresh alkali for cleaning" or "prepare fresh disinfectant for cleaning", and it is necessary to reuse the lotion to clean the next tank or subsystem The time and concentration (volume percentage) of pickling, alkali washing or disinfection washing can be specified by the user Advanced cleaning process: pre washing (no reflux, so as to discharge slag), and one-time washing with pure water after Zui Automatic and reliable control of the whole process Except for the water tank, there are acid, alkali or disinfectant in the pipeline of the whole system, and each cleaning process of the equipment is the self-cleaning process of the system Therefore, the self-cleaning ability of the system The heating mode of water tank is steam heating or electric heating
