鹽城工學(xué)院 本科畢業(yè)設(shè)計說明書 2004 摘 要 新型組合式選粉機(jī)從功能上兼具粗粉分離器和選粉機(jī)性能 變系統(tǒng) 氣 料兩路走為一路走 實(shí)現(xiàn)了簡化系統(tǒng)的目的 本設(shè)計在機(jī)體的分級 結(jié)構(gòu)中將渦流分級 慣性分級 離心分級原理學(xué)科學(xué)地組合在一起 物 料在選粉機(jī)內(nèi)不同部位經(jīng)過了幾次不同方式的反復(fù)分選 清洗 分離徹 底 且從結(jié)構(gòu)上消除了風(fēng)速梯度 保證了分選區(qū)氣流場穩(wěn)定 因而可以 達(dá)到較高的選粉效率 其自帶一組低阻高效旋風(fēng)收塵器 可將 80 的合 格成品收集下來 大大減輕了下一級收塵器的處理壓力和工作負(fù)荷 使 系統(tǒng)的運(yùn)轉(zhuǎn)率更高 投資更省 而且采用下部進(jìn)風(fēng)的型式 使系統(tǒng)阻力 更小 工藝布置更緊湊 關(guān)鍵詞 新型組合式選粉機(jī) 粗粉分離器 分級 新型組合式選粉機(jī)總體及分級部分設(shè)計 Abstract New Combined Separator has Thick Powder Separator simultaneously with Separator performance changing systematic gas and material from two road into one and have realized easier systematic purpose It is designed in organism grade the structural eddy current of lieutenant general grade inertia grade centrifugation grade principle subject study land make up together Stock in Separator different positions have passed the relapse of some of different waives grading wash split thorough It has eliminated the gradient of wind speed just from structure have guaranteed the grading district site of air current stability and may reach higher choose powder efficiency Taking a group of low resistance efficient whirlwind receive dust ware It will qualified finished product of 80 collect also alleviate next a level receipt dust greatly the handling of ware pressure and working load make systematic operation rate higher and make fewer investment Meanwhile it will enter the type of wind with bottom so it will make systematic resistance less technical arrangement more compacter Keywords New Combined Separator Thick Powder Separator Grade
