<p>This invention is related to one kind of precise water resource recycling machine which sends the waste liquid of a collection tank to one or more parallelly connected filtration tubes by a pump. The difference between this invention and the traditional filtration method lies in that it doesn't use methods like siliceous clay, neutralization tank, ceramics, filtration core and centrifugation to filtrate. It controls the waste liquid flow rate sent via the pump by controlling the pressure of the filtration tube to reach the best filtration efficiency and prevent the bag from exploding. Further a multilayer precise filtration bag is used inside the filtration tube to effectively isolate the metal powder of the waste liquid and adequately filtrate the water of the powder by the assistance of air pressure, which makes the highly valuable metal powder be recycled smoothly as well as the recycled water after being filtrated doesn't contain impurities and can be sent back to be used in the process again.</p> |
