ZJO-SEPA高效氣流分級機

 

 

        ZJO-SEPA高效氣流分級機(選粉機)是利用選粉機內空氣渦流在水平方向進行物料分級的一種新型高效氣流粉碎分級機,其分級流場的形成和分級機原理與離心式、旋風式分級機有很大的不同, 因其性能比傳統的選粉機優異,增產節能效果顯著,目前廣泛地用於輕質物料粗分級(比如:PVC材料),ZJO-SEPA高效氣流分級機被認為是第三代高效分級設備的典型代表。

工作原理 

ZJO-SEPA高效氣流分級機即物料從選粉機進料口喂入,通過旋轉的撒料盤均勻撒地向四周,並因擋料圈的阻擋作用,物料以分散狀態下落到導風葉和轉子之間的選粉區內,並同時隨選粉區所形成的空氣渦流在選粉區中運動進行預分級,在選粉渦流中運動的粉塵顆粒同時受重力、風力和旋轉離心力的作用,細小輕微的顆粒隨氣流被吸入轉子內部,經出風口由收塵器收集成為成品;粗重顆粒則下落,最終被收集到下錐體的粗粉出口。改變轉子轉速可改變粉塵顆粒的初速度和選粉區渦流的流線曲率,從而也就改變了顆粒所受風力的方向和離心力的大小,從而可有效地調節成品細度。

設備特點 

ZJO-SEPA高效氣流分級機具有以下幾個特點:
   1、分級氣流從兩側水平切向進入,由於導流葉片和水平分隔板的作用,無論是在環形分級區還是在渦流分級區,氣流都隻作橫向旋轉,即在水平麵內循環。
   2、物料在撒料盤和緩衝板的作用下分散較好,落入環形分級區與平穩的分級氣流相遇,氣固混合比較均勻、氣固比可以較高。
   3、物料垂直下落,從上至下通過整個分級區,在其中停留的時間較長,可受到多次分級的作用。
   4、無論是環形分級區還是渦流分級區,都是形狀比較簡單的狹長環形空間,氣流的運動速度在分級區的任何位置上變化都較小,因麵氣流平穩、幹擾小、粒徑(質量)相同的顆粒的受力情況和運動軌跡基本上是穩定的,顆料的分級是按照明確的力的平衡關係而完成的,分級條件明確而簡單,分級效率和分級精度較高。
   5、環形分級區內的氣流屬於自由渦(半自由渦),可去除較大顆粒,起到預分級和使物料進一步分散、混合均勻的作用,渦流分級區內的氣流屬於強製渦,通過調整分級機轉速可控製分級粒徑的大小,細粉的收集采用與分級機分開安裝的旋風收集器和脈衝袋式除塵器,收集效率高。

ZJO-SEPA high efficiency air classifier

ZJO-SEPA high efficiency air classifier (separator) is a new type of efficient air classifier material classification in the horizontal direction by air swirl separator, the flow field of the formation and classification principle and classifier centrifugal cyclone type classifier is very different, because of its performance than traditional powder selecting machine excellent effect production is now widely used in energy saving, light material rough classification (such as: PVC, ZJO-SEPA, material) air classifier is regarded as a typical representative of the third generation of high grade equipment.

working principle

ZJO-SEPA high efficiency air classifier has the following characteristics:

1. The horizontal air flow is cut horizontally from both sides. Due to the function of the guide vanes and the horizontal partition plate, the airflow is only rotated horizontally in the annular classification zone or in the turbine classification area, i.e., in the horizontal plane.

2.the material scattered in the tray and buffer plate under the role of good dispersion, fall into the ring classification area, and the smooth classification of gas meet, gas and solid mixing more evenly, the gas solid ratio can be higher.

3. the material falls vertically, from top to bottom through the entire classification area, in which the longer stay, can be subjected to multiple grading role.

4.whether it is the annular area or grading turbine classification area, are long and narrow annular space shape is relatively simple, the movement speed of air flow at any locations of the staging area changes are small, because the surface flow smooth, small interference, particle size (mass) locus of stress and movement of the same particle is basically stable the classification of particles is a balance force in accordance with a clear and complete, clear and simple classification, classification precision and efficiency is high.

5.the annular airflow within the classification zone belongs to the free vortex (semi free vortex), can remove larger particles, the pre classification and make the material further dispersed, mixed flow turbine, grading zone belongs to the forced vortex, by adjusting the rotational speed of the classifier can control the size of particle size, fine powder was collected by with the classifier separately and install the cyclone collector pulse bag filter, high collection efficiency.

Equipment introduce

Customers need to provide: ash pump and distribution room to the main wire, cable and other accessories.
