氣力輸送輸灰設備的應用、特點和優勢

  在制藥(yao)行(xing)業的固體(ti)制劑(ji)生(sheng)產(chan)過程中,各生(sheng)產(chan)環節之(zhi)間粉體(ti)輸送設備問(wen)題已(yi)經成為改(gai)進生(sheng)產(chan)工藝與提高產(chan)品(pin)質(zhi)量(liang)的一個重(zhong)要(yao)問(wen)題。在我國的固體(ti)制劑(ji)生(sheng)產(chan)企業中,人工配料(liao)和人工上料(liao)的生(sheng)產(chan)方式普遍存(cun)在。

  在(zai)這(zhe)個(ge)過程中(zhong)(zhong),人(ren)與(yu)(yu)藥(yao)品的(de)接(jie)(jie)觸有三次,物(wu)料經過三個(ge)中(zhong)(zhong)間容(rong)器才(cai)能夠最(zui)終用于下一(yi)步(bu)工(gong)序(xu),這(zhe)不(bu)僅(jin)增(zeng)加了(le)工(gong)人(ren)的(de)勞動(dong)強度,使過程煩瑣化,更重要的(de)是它增(zeng)大(da)了(le)物(wu)料交叉(cha)污(wu)(wu)染的(de)可能,同(tong)時,在(zai)輸(shu)送(song)設備過程中(zhong)(zhong),可能會造(zao)成(cheng)大(da)量的(de)粉塵,污(wu)(wu)染環境(jing)(jing),影響操作者的(de)身(shen)體健(jian)康。有些物(wu)料還(huan)具有易燃,易爆,有毒,有害等特(te)殊性質,就(jiu)更加不(bu)適(shi)宜采用這(zhe)種方(fang)式。在(zai)壓片以及膠囊填充等工(gong)序(xu)中(zhong)(zhong),同(tong)樣存在(zai)這(zhe)種情況,國(guo)內大(da)多數生(sheng)產(chan)廠(chang)家(jia)仍在(zai)采用人(ren)工(gong)上料。而最(zui)理想(xiang)的(de)輸(shu)送(song)設備方(fang)式應該(gai)是:盡量減(jian)少人(ren)與(yu)(yu)物(wu)料的(de)直接(jie)(jie)接(jie)(jie)觸,使物(wu)料的(de)輸(shu)送(song)設備在(zai)一(yi)個(ge)封閉(bi)的(de)環境(jing)(jing)中(zhong)(zhong)完成(cheng),這(zhe)樣,既可以節(jie)省人(ren)工(gong),降低成(cheng)本,又可以避免交叉(cha)污(wu)(wu)染,提高(gao)了(le)固(gu)體制劑(ji)生(sheng)產(chan)過程的(de)自動(dong)化程度。

  對于目前國內(nei)的(de)(de)(de)固體制(zhi)劑中(zhong)的(de)(de)(de)粉體輸(shu)(shu)送(song)(song)(song)設(she)(she)(she)(she)(she)(she)備(bei)(bei),我們(men)總(zong)結主要(yao)有(you)(you)以下(xia)幾種(zhong)(zhong)(zhong)幾種(zhong)(zhong)(zhong):正(zheng)壓(ya)輸(shu)(shu)送(song)(song)(song)設(she)(she)(she)(she)(she)(she)備(bei)(bei),負壓(ya)輸(shu)(shu)送(song)(song)(song)設(she)(she)(she)(she)(she)(she)備(bei)(bei)和(he)提升(sheng)機(ji)上料(liao)等。這幾種(zhong)(zhong)(zhong)形(xing)式都可以基(ji)本滿(man)足降低(di)(di)工(gong)人勞(lao)動強度,減少(shao)粉塵,保護物(wu)(wu)料(liao)不(bu)受環(huan)境污染(ran)等要(yao)求,但(dan)是這幾種(zhong)(zhong)(zhong)形(xing)式又(you)(you)各有(you)(you)利(li)弊(bi),下(xia)面我們(men)分別簡要(yao)介紹這幾種(zhong)(zhong)(zhong)方(fang)式的(de)(de)(de)優(you)劣:正(zheng)壓(ya)輸(shu)(shu)送(song)(song)(song)設(she)(she)(she)(she)(she)(she)備(bei)(bei)又(you)(you)主要(yao)分兩種(zhong)(zhong)(zhong)形(xing)式:高(gao)壓(ya)輸(shu)(shu)送(song)(song)(song)設(she)(she)(she)(she)(she)(she)備(bei)(bei)和(he)低(di)(di)壓(ya)輸(shu)(shu)送(song)(song)(song)設(she)(she)(she)(she)(she)(she)備(bei)(bei),高(gao)壓(ya)輸(shu)(shu)送(song)(song)(song)設(she)(she)(she)(she)(she)(she)備(bei)(bei)的(de)(de)(de)輸(shu)(shu)送(song)(song)(song)設(she)(she)(she)(she)(she)(she)備(bei)(bei)能(neng)力(li)比較大(da),輸(shu)(shu)送(song)(song)(song)設(she)(she)(she)(she)(she)(she)備(bei)(bei)距離長,但(dan)是其設(she)(she)(she)(she)(she)(she)備(bei)(bei)較復雜,笨重(zhong),安(an)裝困難,而且部(bu)件價格比較高(gao),高(gao)壓(ya)輸(shu)(shu)送(song)(song)(song)設(she)(she)(she)(she)(she)(she)備(bei)(bei)對管道和(he)物(wu)(wu)料(liao)都有(you)(you)較大(da)磨損(sun),且有(you)(you)泄(xie)露的(de)(de)(de)可能(neng)。低(di)(di)壓(ya)輸(shu)(shu)送(song)(song)(song)設(she)(she)(she)(she)(she)(she)備(bei)(bei)系統對物(wu)(wu)料(liao)的(de)(de)(de)磨損(sun)比較小,但(dan)其輸(shu)(shu)送(song)(song)(song)設(she)(she)(she)(she)(she)(she)備(bei)(bei)能(neng)力(li)有(you)(you)限,同樣(yang)有(you)(you)泄(xie)露的(de)(de)(de)可能(neng)。提升(sheng)機(ji)上料(liao)的(de)(de)(de)方(fang)式目前制(zhi)藥廠家采用(yong)較多的(de)(de)(de)一(yi)種(zhong)(zhong)(zhong)方(fang)式,但(dan)是其占(zhan)地面積較大(da),能(neng)耗高(gao),操作(zuo)控制(zhi)較為(wei)復雜,也(ye)并(bing)非物(wu)(wu)料(liao)輸(shu)(shu)送(song)(song)(song)設(she)(she)(she)(she)(she)(she)備(bei)(bei)形(xing)式的(de)(de)(de)首(shou)選。

  粉體輸送設備即真空輸送設備,它是采用全密閉輸送設備系統完成對散裝物料(粉體,顆粒)的運輸,這就完全杜絕了由于物料泄露造成的對環境的污染和對操作人員身體的傷害,以及周圍環境對于物料的污染。是近年來粉體輸送設備的發展方向。真空上料機的負壓源有(you)多種(zhong)形式(shi)(shi),例如:真(zhen)空(kong)(kong)發(fa)(fa)生(sheng)器(qi)、真(zhen)空(kong)(kong)泵、羅茨(ci)風(feng)機(ji)(ji)(ji)等。真(zhen)空(kong)(kong)發(fa)(fa)生(sheng)器(qi)的優(you)點是體(ti)(ti)積小、重量輕(qing)、便于安(an)裝,可(ke)應用(yong)在(zai)潔凈廠房內(nei)它(ta)采用(yong)射(she)流技術(shu),使真(zhen)空(kong)(kong)發(fa)(fa)生(sheng)器(qi)在(zai)壓縮空(kong)(kong)氣的作用(yong)下產生(sheng)高真(zhen)空(kong)(kong)實現(xian)對(dui)(dui)物料的輸(shu)送(song)設備(bei),不(bu)需(xu)要機(ji)(ji)(ji)械式(shi)(shi)真(zhen)空(kong)(kong)泵,沒有(you)任何潤滑元件,也(ye)幾(ji)乎(hu)沒有(you)運動部件,完全符合GMP要求。氣動真(zhen)空(kong)(kong)輸(shu)送(song)設備(bei)系統主(zhu)要應用(yong)于制藥,食品(pin)行業(ye)的粉狀(zhuang)、顆粒狀(zhuang)等固體(ti)(ti)物料的輸(shu)送(song)設備(bei)和上料。可(ke)與(yu)混(hun)合機(ji)(ji)(ji)、制粒機(ji)(ji)(ji)、壓片機(ji)(ji)(ji)、包(bao)衣機(ji)(ji)(ji)、膠(jiao)囊充填機(ji)(ji)(ji),包(bao)裝機(ji)(ji)(ji)等主(zhu)要工(gong)藝(yi)設備(bei)配套使用(yong);隨著其(qi)在(zai)中(zhong)國(guo)的不(bu)斷推廣(guang)應用(yong),必將(jiang)會對(dui)(dui)我國(guo)在(zai)該領域優(you)化生(sheng)產工(gong)藝(yi)流程,有(you)效地減(jian)少了(le)交(jiao)叉污染與(yu)粉塵,對(dui)(dui)提(ti)高藥品(pin)生(sheng)產品(pin)質起(qi)到(dao)積極作用(yong)。
