  • the shaft separates the inner wall of the screen filter by brush, and the particles that are lined up are driven by the flow of fluid into the Drain nozzle and the output of the machine due to the turbulence generated by the flow through the nozzles on the shaft.
  • This wash is set to 30 seconds by the designer, and then the outlet valve is opened and the Drain valve is closed, but at this time, the triple valve on the inlet nozzle (3-WAY VALVE) disconnects the input current And directs the flow to the output of the back trace. At this time, the liquid is fed from the outlet and directed from the inlet to the back trace and all the particles that are trapped in the gravel are driven out of the machine. After a specified time (up to 5 minutes), the three-way valve changes to the liquid state and returns to the main filtration state of the machine and resumes its normal operation system .

Abstract

L'invention concerne un filtre intégral à combinaison automatique, utilisant un filtre à sable et un filtre à tamis sous la forme d'un dispositif, et l'utilisation d'une automatisation et d'un lavage automatique du traitement d'eau et de liquides. Il s'agit d'un dispositif de purge physique pour toutes les particules jusqu'au maillage spécifié par le concepteur, qui n'est pas le même selon différents besoins. Le fluide sale est admis à partir de l'entrée et le liquide nettoyé est retiré à partir de la sortie. En cas de besoin de lavage à contre-courant, un dispositif qui détermine la différence de pression d'entrée et de sortie est utilisé, puis des vannes électriques qui sont ouvertes et fermées sur l'entrée et la sortie sont installées par le circuit de commande, de sorte que le flux d'eau depuis la sortie jusqu'à l'entrée de conduction et les particules et les contaminants soient évacués du système.
