Band warm table following formula collecting and filtering apparatus of the present invention (comprise nanofiltration/reverse osmosis, and heating), many and be difficult for reclaiming at the dense water of present all kinds of collecting and filtering apparatus system, the pressure pot hypertonia causes shortcoming such as failure rate height to make improvements.(hydraulic pressure 〉=0.2MPa) or the pure water that does not have an area, direct-furnish water source are produced and are heated, and total system can be moved under tap water pressure drives, and utilizes magnetic valve protection rear end equipment to prevent waterflooding to be specially adapted to general municipal direct-furnish tap water.And accomplish dense water recycling.
Band warm table following formula collecting and filtering apparatus principle of work:
When former water is that the municipal tap water is (during hydraulic pressure 〉=0.2MPa): when pure water water tank 6 liquid levels are discontented, the liquid level signal switch sends signal to magnetic valve 1 and opens, tap water is through magnetic valve 1, Hall under meter 3 then when pre-treatment 4 and nanofiltration device 5, pure water and dense water enter pure water water tank 6 and dense water water tank 13 respectively, and dense water is drained through arranging dense magnetic valve 14.When pure water water tank 6 water were full, liquid level signal sends signal closed magnetic valve 1, cut off former water and stopped water processed, and liquid level signal sends to automatically controlled leading 8 prompting pure water water simultaneously expires.Dense water water tank 13 has the liquid level signal switch, and when dense water water tank 13 water were full, liquid level switch sent signal and gives automatically controlled leading 8 prompting water full.When opening automatically controlled leading 8 pure water buttons, pure water water outlet water pump 7, magnetic valve 9 are opened, and magnetic valve 10 cuts out, and pure water flows out from automatically controlled leading 8 through pure water water outlet water pump 7, magnetic valve 9; When opening automatically controlled leading 8 dense water buttons, dense water flows out from automatically controlled leading 8 through dense water water outlet water pump 12; When opening automatically controlled leading 8 boiling water buttons, pure water water outlet water pump 7, magnetic valve 10 are opened, and magnetic valve 9 cuts out, pure water through pure water water outlet water pump 7, magnetic valve 10 then through heating tank 11 heating backs from automatically controlled leading 8 outflows.When liquid level signal was malfunctioning, too much dense water, pure water can flow into water drain by overflow port.Hall under meter 3 relies on current to promote the motion of under meter internal impeller and also spreads out of pulse signal, and is in order to monitor pipeline current size, less or when not having the current signal, the Hall under meter sends signal and needs to change for automatically controlled leading 8 prompting filter cores when water-flow signal.
When the non-direct-furnish of former water water source (during hydraulic pressure≤0.2MPa): when pure water water tank 6 liquid levels are discontented, the liquid level signal switch sends signal to magnetic valve 1, booster water pump 2 and opens, tap water is through magnetic valve 1, booster water pump 2, Hall under meter 3 then when pre-treatment 4 and nanofiltration device 5, pure water and dense water enter pure water water tank 6 and dense water water tank 13 respectively, and dense water is drained through arranging dense magnetic valve 14.When pure water water tank 6 water were full, liquid level signal sends signal closed magnetic valve 1, booster water pump 2, cut off former water and stopped water processed, and liquid level signal sends to automatically controlled leading 8 prompting pure water water simultaneously expires.Dense water water tank 13 has the liquid level signal switch, and when dense water water tank 13 water were full, liquid level switch sent signal and gives automatically controlled leading 8 prompting water full.When opening automatically controlled leading 8 pure water buttons, pure water water outlet water pump 7, magnetic valve 9 are opened, and magnetic valve 10 cuts out, and pure water flows out from automatically controlled leading 8 through pure water water outlet water pump 7, magnetic valve 9; When opening automatically controlled leading 8 dense water buttons, dense water flows out from automatically controlled leading 8 through dense water water outlet water pump 12; When opening automatically controlled leading 8 boiling water buttons, pure water water outlet water pump 7, magnetic valve 10 are opened, and magnetic valve 9 cuts out, pure water through pure water water outlet water pump 7, magnetic valve 10 then through heating tank 11 heating backs from automatically controlled leading 8 outflows.When liquid level signal was malfunctioning, too much dense water, pure water can flow into water drain by overflow port.Hall under meter 3 relies on current to promote the motion of under meter internal impeller and also spreads out of pulse signal, and is in order to monitor pipeline current size, less or when not having the current signal, the Hall under meter sends signal and needs to change for automatically controlled leading 8 prompting filter cores when water-flow signal.
