產(chǎn)品概述

DZBL高效密閉板式過濾機屬于葉片過濾機，是我司在借鑒國外技術的基礎上設計開發(fā)的新一代過濾設備，是一種高效、節(jié)能、密閉操作的精密清過濾設備。該產(chǎn)品設計結構獨特，體積小，過濾波動，過濾效率高、濾液透明度和澄清度好，無物料消耗。不消耗濾紙，濾布或濾芯，只消耗少量的助濾劑，因而過濾成本很低，設備操作、維護、清理方便。該設備可以定制為手動排渣和自動排渣兩種，過濾面積從2 平方到200平方，根據(jù)過濾的工藝要求，密閉容器有碳鋼與不銹鋼兩種材質(zhì)供用戶選擇。

Product Instruction

DZBL high efficiency inclosed leaf filter belongs tostainless steel woven mesh filter. It is the new generation filtration equipment that we developed refferencing foreign technology. The filter has unique and compacted design, and high filtering efficiency. It does not consume the filter cloth, filter paperor filter cartridge, just uses a little filter aid, so thee filtration cost is low. And the machine is easy to operate， maintain and clean. Manual discharging and auto discharging are available according to custorner's，requirement. The filter area ranges from 2 m2 to 200 m2. The housing material can be carbon steel or stainless steel to meet clients' different needs.

主要結構及工作原理

DZBL型高效密閉板式過濾機主體是由殼體、濾網(wǎng)片、起蓋機構、自動排渣裝置等組成，還可以根據(jù)過濾介質(zhì)的不同定制完整的過濾系統(tǒng)（含過濾器主機和混合缸、輸送泵、輸送泵、管道、閥門、電氣控制等），其中濾網(wǎng)片是由多層不銹鋼網(wǎng)組成，安裝在中心集料管上，裝拆清理十分方便。

助滲劑在混合缸中與物料混合后，通過輸送泵打循環(huán)使得滾網(wǎng)片上形成得定的濾餅層，即進行助誘劑預涂。預涂好后開始過滾，細小的助濾劑顆粒可提供無數(shù)的細微通道，圖住懸浮的雜物，只容許清意的流體通過，并在過渡過程中通過不斷添加硅藻土等助誘劑以形成新的過濾層，使得濾餅不會有所堵塞，這樣物料就通過濾浮顯進行實質(zhì)性的過濾，去其雜質(zhì)，流入滾葉內(nèi)腔，再經(jīng)出液管，流量，流管，流出清液，流液，如果過濾時需要脫色，還需加入一定比例的活性碳。若用于機榨毛油等比較臟的液體固液分離作業(yè)，則無需添加助濾劑。

Structure & Principle

The leaf filter consists of filter housing, filter screen, head lifting device and discharging device. According to the different filter materials it can customize various whole filtration system (Include the filter, mixing tank, feeding pump, pipes, valves, ccontrol system, etc.). The leaf is made of layers of sstainless steel wire screens, then installed on the central filtrate collecting tube, so it's convenient to discharge and clean.

The material mixed with filter aids in the mixingtank first, then pumped it into the filter circularlyto form a layer of filter cake. This process called the diatomite precoating and then begin to filter. The tiny filter aid particles can provide countless wispychannels to block the suspended solids, and onlythe clean liquid can go through. And while filtering,the new layers will be formed, and it will not cause block, thus realize filtering via filter cake layer. When filtering, if need decoloration, activated carboln might be needed. If filter the dirty liquid, such assqueezed crude oil, no need adding the filter aid.
