一、多輥篩分除塵機特征性能介紹：

多輥篩分除塵機是配套秸稈清潔制漿工藝流程中的備料設(shè)備，功能是篩分、除塵凈化作用。適用于麥草、稻草、蘆葦、蔗渣等原料。收購的草類秸稈原料內(nèi)總會夾雜著部分泥、砂、土塵等雜質(zhì)，這部分雜質(zhì)不篩除，會對后續(xù)設(shè)備造成嚴重磨損及破壞，還會影響制成的纖維灰分大、質(zhì)量不合格的因素。

一、Multi-roller screening dust collector：

Multi-roller screening dust collector It is a necessary equipment for raw material screening and dust removal in straw clean pulping process。Suitable for the screening and dust removal process of straw and wheat straw。The purchased wheat straw and straw will be mixed with a lot of mud, sand, dust and other sundries，If these impurities are not screened out, the ash content of the fiber will be unqualified, and the equipment for subsequent processing will be damaged。It will also affect the factors of high ash content and unqualified quality of the fiber.

二、進入原料要求及工作原理：

要求投入原料長度在3-8厘米之間，由切草機切草后直接送至多輥篩分除塵機內(nèi)，該設(shè)備一般由4-6組翻拋輥組成，輥子的周圍安裝著翻拋草料的叉板，類似于羊角，所以我們也稱之為羊角輥。每組翻料輥的底部都裝有過濾泥砂的篩板，篩板裝拆采用快插式結(jié)構(gòu)設(shè)計，便于快速抽出和更換。麥秸物料由進料口進入篩分除塵器。在羊角輥高速旋轉(zhuǎn)并不斷向前運動的同時，給料機翻轉(zhuǎn)，給料機在此過程中實現(xiàn)了篩分、除渣過程。將混入麥秸中間的泥、細砂、粉塵等雜質(zhì)進行摔打、拋擲、分離，較重的泥、砂通過底部的篩孔落下，與麥秸原料分離。頂部的空氣除塵裝置將極細的粉塵吸出并分離。細粉塵進入除塵設(shè)備的脈沖除塵器收集凈化后的空氣后在高空放。干凈的稻、麥草秸稈從水平出料口拋入皮帶機，進入下一道工序。   

二、Input raw material requirements and working principle：

It is required that the length of the input raw materials is between 3-8 cm, and the grass is cut by the grass cutter and sent directly to the multi-roller screening dust remover. This equipment is generally composed of 4-6 groups of turning rollers, and fork plates for turning and throwing grass are installed around the rollers, which are similar to the horns, so we also call them claw rollers。The bottom of each turning roller is provided with a sieve plate for filtering mud and sand。

The sieve plate is assembled and disassembled with quick plug-in structure design, which is convenient for quick extraction and replacement。Wheat straw material enters the screening dust collector from the feed inlet. While the goat horn roller rotates at high speed and keeps moving forward, the feed is turned over, and the feed realizes the screening and slag removal process in this process。Impurities such as mud, fine sand and dust mixed in the middle of wheat straw are beaten, tossed and separated, and heavier mud and sand fall through the sieve holes at the bottom and are separated from wheat straw raw materials。Very fine dust is sucked out and separated by the air-induced dust removal device at the top。Fine dust enters the pulse dust collector of dust separation equipment to collect purified air and then is released at high altitude。Clean wheat straw is thrown into the belt conveyor from the horizontal discharge port，Enter the next process。
