A MEDICINES INVESTMENT EQUIPMENT AND METHOD OF WATER SUPPLY FACILITIES

摘要

The present invention relates to a chemical input device of a water supply facility using an underground well, and in particular, an underwater pump controlled by a control panel is installed in an underground well, and the water pumped by the underwater pump is transmitted and stored in a water tank through a water pipe. A water supply facility for supplying to each consumer afterwards, comprising: a return hose for retrieving part of the water drawn out from the suspension of the water pipe and extending to the underground well to be fed through the water pipe; A medicine storage container installed at a stop of the return hose and supplying a medicine to the water returned through the return hose; Is installed between the feedback hose and the chemical storage container and comprises an electromagnetic valve for opening and closing the flow path of the feedback hose by the drive signal of the submersible pump,;Purification and disinfecting chemicals using the chemical input device configured as above, but when the water level detected by the water level sensor installed in the water tank is lower than the preset level, the solenoid valve and the water installed in the stop of the return hose connected to the chemical reservoir When the driving signal is transmitted to the pump, the submersible pump is pumped by the transmitted driving signal, and when the water is sent to the water pipe, some of the water is returned to the return hose to be returned to the well, and the medicine stored in the medicine storage container is returned. It is discharged from the medicine reservoir by the pressure of the water returned through the hose is mixed with the water of the return hose is supplied to the well.
