The invention provides a rotary filter screen structure,It is mainly composed of a water tank,A water outlet is arranged at one end of the sink,The water tank can be filled with liquid,For collection and supply of liquids,A filter screen device which can rotate up and down is arranged above the water tank,A water pipe is arranged at the front end of the filter screen device,A nozzle is arranged at the end edge of the water pipe,A fan is arranged at the back end of the filter screen device,It is used as a suction,A motor is arranged on the side of the water tank,As the extraction water and delivery water,A water supply port is arranged at one end of the motor,A water inlet is arranged at the other end of the motor;By these combinations,Fill the water tank with water,Turn on the motor,The motor will pump water into the water pipe,The nozzle at the end edge of the water pipe starts to spray water towards the screen device,Turn on the fan,When dust impurities are extracted by fan,Since the screen device can rotate up and down,As a result, the dust impurities will be brought into the water tank by the screen device due to rotation and deposited at the bottom of the water,Therefore, the ejected liquid can spray the waste gas and make the dust and dirt fall down,Make the discharge clean,Achieve the effect of filtering dust and dirt.本創作提供一種轉動式濾網過濾構造,主要由一水槽所構成,於水槽一端設一出水口,水槽內部可盛裝液體,作為收集及供給液體使用,水槽上方設一可上下轉動之濾網裝置,於濾網裝置之前端設一水管,於水管端緣處設噴嘴,於濾網裝置後端設一風扇,係作為一抽風用,於水槽側邊設一馬達,作為抽出水液及送出水液,於馬達一端設一供水口,於馬達另一端設一入水口;藉上述組合,將水槽內裝入水液,開啟馬達轉動,馬達將抽送水液進入水管內,水管端緣處之噴嘴開始朝濾網裝置噴水,開啟風扇,當粉塵雜質被風扇抽出時,由於濾網裝置可上下轉動,因此該粉塵雜質將被濾網裝置因轉動而帶至水槽內並沉積於水底,因此該噴出之液體可對該廢氣噴灑而使該粉塵污物往下掉落,使排出為較乾淨之氣體,達到過濾粉塵污物之功效。
