LFU032外吸式轉籠濾塵器主要用于分離空氣中細小塵雜的過濾設備。它可以廣泛應用于各類紡織廠各工序含塵空氣的第二級精過濾，和各車間空調系統(tǒng)的回風過濾。

　　整機由轉籠筒體、傳動吸嘴部件、墻板機架三大部分組成。需安裝在密閉的空間內。通過外部風機的抽吸作用，含塵空氣從轉籠外向內流動，塵雜截留在筒體表面濾料上，塑料吸嘴端部與轉籠筒體表面相接觸，由往復絲杠帶動，左右往復，一端與固定吸風管相通，在固定吸風管尾端通過管道與集塵風機入口相連，使吸嘴能周期性的逐點吸清濾料表面的塵雜，潔凈空氣則通過轉籠從敞開端流出，通過風機排放或進入空調室處理。

　　當外吸式轉籠濾塵器用于紡織廠清棉、梳棉、廢棉等工序含塵空氣過濾時，只能作為第二級精過濾之用，需同時配備相應的第一級過濾設備(如自吸式回風過濾器等)，含塵空氣先經(jīng)第一級過濾設備，再進入本機。此時濾料可以選用長毛絨、針織絨或無紡布。

LFU032 model external suction rotary drum filter is mainly used for separation of air and dust particles, which is widely applied in the secondary further dusted air filtration of various processes and return air filtration of air conditioning system in textile plants.

The whole filter consists of rotary drum, drive suction nozzle and wallboard frame. Filter should be installed in closed space. By suction effect of external fan, dusted air flows into rotary drum. Dusts and other impurities are filtered and left on filtering material of rotary drum screen surface. One end of plastic suction nozzle terminals, droved by traverse guide screw to make reciprocating motion, is connected to screen surface. The other end is connected to fixed air suction tube. The outlet of air suction tube is connected to the inlet of dust collecting fan, which is used for collecting dust and impurities on screen surface. After the filtering process, clean air runs into air conditioning chamber through the open end of rotary drum or sets free by fan.

When external suction rotary drum filter is applied for filtering of picking, combing and processing waste cotton, it can be used for secondary further filter only, and coupled with filter devices such as self-suction return air filter for primary filtering. Flush, knitting or non-woven fabric can be used as filtering material.

處理風量、濾料選用表 Air capacity & filter material selecting list:

　　處理風量與機器使用場合和生產(chǎn)品種有關，如被過濾空氣的含塵濃度越大，則處理風量越小，客戶訂貨時應根據(jù)實際情況按上表數(shù)據(jù)正確選型。

Selection of air capacity depends on specific occasion in which the device is applied and the products variety. Higher concentration of dust in the air requires lower air capacity. Clients can choose appropriate specifications based on practical situations.
