Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a simple and easy filling system of hydrogen peroxide based on PLC control system, including storage bottle 1, float 2, connecting piece 3, solenoid valve 4, hose 5, peristaltic pump 6, fixed plate 7 and the main cavity body 8, 1 inside floats 2 that is provided with of storage bottle, and 1 bottom of storage bottle is provided with connecting piece 3, connecting piece 3 and solenoid valve 4's access connection, and solenoid valve 4's export is passed through hose 5 and is connected with the feed inlet of peristaltic pump 6, the discharge gate of peristaltic pump 6 passes through hose 5 and is connected with the main cavity body 8, and peristaltic pump 6 passes through on the fixed main cavity body 8 of fixed plate 7.
The bottom of the storage bottle 1 is provided with threads, and the floater 2 is connected with the storage bottle 1 through the threads, so that the storage bottle is more convenient to mount and dismount.
The floater 2 is electrically connected with a PLC (programmable logic controller) of the human-computer interface, the PLC is in control connection with the electromagnetic valve 4 and the peristaltic pump 6, the floater 2 is connected with X07 on a chip of the PLC, the electromagnetic valve 4 and the peristaltic pump 6 are connected with Y4, and the PLC is connected with the human-computer interface through a communication line.
