          旋流器 Hydrocyclone

            

          產品介紹(Introduction Of Hydrocyclone)

           

          星源工程師主要采用CFD模型軟件、ANSYS計算機模擬流場分析軟件、SolidWorks三維作圖應力分析軟件設計,結合多年的實踐經驗,保證旋流器結構設計最優化,得到了Smax系列旋流器,由導向螺旋漸開線進料體及、10°、15°、20°、45°、60°、180°、多錐度等錐體結構組成。

          XING-YUAN engineers mainly adopt CFD model software, ANSYS computer simulation of flow field analysis software, and Solid Works 3D drawing stress analysis software, combined with years of practical experience, ensure the cyclone structure design optimization, acquire Smax series cyclone,which include special type feeding chamber structure, 8°、10°、15°、20°、45°、60°、180°、and multi cone structure.

          XING-YUAN in view of the special slurry grading process, provide ANSYS computer simulation of flow filed calculation model selection, grading concentrate desliming laboratory service, and customized design cyclone.

           

          產品特點(Features

           

          采用漸開線進料體及雙錐體設計:進口阻力小能耗低、處理量大、分級精度高。

          Involute feed chamber and double cone design: small resistance and low energy consumption,large capacity and high precision grading.

           

           

          旋流器定義及原理 (Definition And Principle)

           

          旋流器是利用離心力場,加速料漿中固體顆粒沉降和強化分離過程的有效分離設備,由上部筒體和下部錐體兩大部分組成的非運動型分離設備。

          Hydrocyclone is the effective separation equipment which is using centrifugal force field, accelerate the settlement of solid particles in the slurry, and also is the non-sports separation device equipment that composed by upper cylinder and lower cone.

           

          料漿以一定壓力及流速(其中給料壓力通常為40-150Kpa,流速為1.6-3/秒)被送入旋流器內,當料漿進入旋流器室后由于料漿中的顆粒受到的離心力、向心力、液體曳力不同,并在自身重力的共同作用下,沿器壁螺旋向下離心運動,從而使固體顆粒在離心力的作用下向外甩出,形成外旋流。給礦壓力越高,離心力越大,該離心力通常為重力的數倍。

          Slurry with certain pressure and flow rate that feeding into cyclone, feeding pressure usually is 40~150Kpa, flow rate is 1.63~3m/s, when the slurry into the cyclone chamber, because of centrifugal force, centripetal force and fluid drag force are different, and under the joint action of its own gravity, the particle in the slurry along the wall spiral downward centrifugal movement, so that the solid particles under the action of centrifugal force thrown outwards, forming the outer flow. The higher the feed pressure, the greater the centrifugal force, the centrifugal force is usually several times of gravity.

           

          固體顆粒被外旋流拋向旋流器內壁,沿錐體螺旋下降,然后作為沉沙從沉沙口排出,而大部分液體則螺旋而上通過內螺旋經溢流管流出。隨介質經溢流流出的固體物質主要是一些細小微粒。在一定的給料壓力和轉速下,旋流器會存在一個分級粒徑,此時阻力與離心力平衡。小于分級粒徑的顆粒隨液體介質由溢流排出,而大于分級粒徑的顆粒則經沉沙口排出旋流器。所謂分級粒徑為旋流器大小選擇的標準,通常為預切分點。

          Solid particle forwarding the inner wall of cyclone by outer vortex, along the cone downward spiral, then discharge from Apex, while most of the slurry up through the spiral flow and discharge from overflow pipe. Solid material from the overflow pipe is mainly fine particles. Under the certain feeding pressure and rotational speed, cyclone has a grading size, and the resistance and centrifugal force balance at this time. The particle less than grading size will discharge with liquid medium, and greater than the grading size will discharge by Apex. So the grading size is the selection standard of cyclone size, usually called pre-slit point.
