反沖式自清洗過濾器Backwashself-cleaningfilter【基本說明】：反沖式自清洗過濾器用于過濾和攔截低粘度液體中的顆粒雜質(zhì)

詳細(xì)介紹

反沖式自清洗過濾器

Backwash self-cleaning filter

【基本說明】：

反沖式自清洗過濾器用于過濾和攔截低粘度液體中的顆粒雜質(zhì)。它優(yōu)秀的結(jié)構(gòu)設(shè)計和自動清潔的功能為用戶帶來了穩(wěn)定可靠的操控性能，同時也大幅度消減了運行維護(hù)費用。

反沖式自清洗過濾器采用線隙式或超級編織網(wǎng)式不銹鋼濾芯，內(nèi)部集成多只楔形濾元，過濾精度從30到3000微米，同時保證了工藝介質(zhì)中污染顆粒的高濾除率。當(dāng)過濾器監(jiān)測到濾芯污堵時就會啟動在線自動清洗過程，在此清洗過程中并不影響過濾器出口液流的連續(xù)性。

有多種不同規(guī)格大小的過濾器可供選擇，單臺反沖洗過濾器能夠處理的流量可達(dá)8000m3/h。

靈活的材質(zhì)和部件的不同組合以及可單獨調(diào)整的控制參數(shù)使這種反沖自清洗過濾器能夠應(yīng)用于各種領(lǐng)域。

Basic Specification:

Backwash self-cleaning filters are applied to filter and intercept particulate impurities in low-viscosity liquids. Its excellent structure design and automatic cleaning function bring stable and reliable operation performance to users, but also greatly reduce the cost of operation and maintenance.

The backwash self-cleaning filter is made of wire-gap or super-braided stainless steel mesh filter element, which integrates several wedge-shaped filter elements. The filtering accuracy is from 30 to 3000 microns, and thus the high filtration rate of contaminated particles in the process medium is guaranteed. When the filter detects the filter plug, it will start the online automatic cleaning process, which does not affect the continuity of the liquid flow at the outlet of the filter.

There are alternative filters of many kinds with different sizes. The maximum handle flow rate of a single backwash filter can be 8000m3/h.

Flexible materials, different combinations of components and control parameters individually adjusted, make it can be applied in various fields.

【結(jié)構(gòu)及工作原理】：

反沖式自清洗過濾器主要組件有：電機、電控箱、控制管路、主管組件、濾網(wǎng)組件、框架組件、傳動軸、進(jìn)出口連接法蘭等。

過濾過程：反沖式自清洗過濾器液體從過濾器進(jìn)口流入，部分液體直接從濾元下端進(jìn)入過濾器，另一部分從中間分流管中進(jìn)入過濾器頂部后，再從濾網(wǎng)上端流入，液體從濾網(wǎng)上下開口同時流入，透過濾網(wǎng)內(nèi)表面在出口匯集流出。顆粒雜質(zhì)被攔截在濾網(wǎng)內(nèi)表面，累積成濾餅，使進(jìn)出口之間壓差逐漸變大，表明濾餅達(dá)到一定厚度，此時濾網(wǎng)通量逐漸減小。

反沖洗過程當(dāng)達(dá)到設(shè)定壓差或時間，自清洗動作啟動，減速電機驅(qū)動反沖洗轉(zhuǎn)臂對準(zhǔn)一支或一組濾網(wǎng)，濾網(wǎng)上端被封住，下端連接到清洗吸嘴，打開反沖洗閥，將濾網(wǎng)與排污管接通，濾網(wǎng)外側(cè)與排污口之間的壓差驅(qū)使濾出清液反向流動沖洗濾網(wǎng)內(nèi)表面濾餅，并排入排污管道。一支/組濾元反沖洗完畢后，關(guān)閉反沖洗閥，清洗轉(zhuǎn)臂對準(zhǔn)下一支/組濾網(wǎng)進(jìn)行反沖洗。濾網(wǎng)被逐支/組反沖洗后，整個過程完成。

定位功能：減速電機驅(qū)動轉(zhuǎn)軸上安裝有定位盤及清洗轉(zhuǎn)臂，定位盤上的每個定位孔分布與每根濾網(wǎng)對應(yīng)，清洗轉(zhuǎn)臂與其中一個定位孔對應(yīng)，定位孔到達(dá)定位傳感器感應(yīng)通道時，定位傳感器輸出信號使電機停止轉(zhuǎn)動，清洗轉(zhuǎn)臂已對準(zhǔn)一支濾元，反沖洗閥打開數(shù)秒后關(guān)閉，清洗完成，電機繼續(xù)運轉(zhuǎn)，下一個定位孔再次將定位傳感器導(dǎo)通，電機停止后清洗下一支濾元。

Structure and working principal：

The recoiling-type self-cleaning filter are mainly composed of motor, electric cabinet, control pipe, main pipe, strainer, frame, transmission shaft, inlet and outlet connecting flange, etc.

Filtration process: the liquid flows into the filter from the inlet of the filter, part of the liquid enters the filter directly from the lower end of the filter element, and another part enters the top of the filter from the middle splitter pipe, and then flows into the upper end of the strainer. The liquid flows into the upper and lower openings of the filter net simultaneously, and flows out through the inner surface of the filter net at the outlet. Particle impurities are intercepted on the inner surface of the filter net and accumulate into filter cake, which gradually increases the pressure difference between inlet and outlet, indicating that the filter cake reaches a certain thickness and the flux of the filter net gradually decreases.

Backwash process: when it reaches the pre-set pressure difference or time, self-cleaning action starts. The deceleration motor driven back flush jib aligns at a or a set of mesh, the strainer is sealed, the upper bottom is connected to the suction nozzle cleaning, the back flush valve is opened, and strainer and drainage pipe is connected. The pressure difference between the outlet of the strainer and discharging outlet drives filter reverse flow to flush filter cake on the inner surface, and into the sewage pipe. After the backwashing of one filter unit/group is completed, the backwashing valve is closed and the cleaning arm align the next filter unit/group for backwashing. The whole process is completed after each filter is backwashed.

Positioning function: positioning plate and cleaning arm are installed on the drive shaft of deceleration motor, every location hole distributed on the plate complete compliance with each strainer, so does the cleaning jib and one positioning hole. When positioning hole arrives at the induction channel of positioning sensors, positioning sensor output signal to stop the motor, and meanwhile, cleaning arm has aligned a filter element, the flush valve opens for several seconds then closes. And cleaning is completed, the motor continues working with a positioning hole conduction with positioning sensors again, then motor stops, and the next filter element cleaning starts.
