摘要
本文在分析單筒式回轉烘干機存在問題的基礎上，介紹了套筒式回轉烘干機的結構特點和工作原理，并依據(jù)該機在水泥廠的使用效果、實測數(shù)據(jù)和計算結論，說明該機無論在理論還是實踐中都是一種高效、節(jié)能的理想烘干設備。套筒式烘干機是通過對單筒烘干機的單一筒體改為疊在一起的兩筒或三筒，以縮短烘干機的外形尺寸。該機工作時，物料和熱氣流依次進入內外筒體，在烘干機內作“V”或“N”形往復折流后，充分利用熱能烘干物料后再卸出。該烘干機筒體部分由兩個筒軸水平放置的內外套筒組成，內通為一錐筒，外筒為直筒，這就使通體的截面得到充分利用，其筒體外形總長度約為相當?shù)膯瓮驳?0％－60％，從而大幅度的減少了占地面積和廠房建筑面積。套筒式烘干機將以其結構緊湊、占地面積小、熱效率高、投資省、適應性強、運轉可靠等特點，為水泥廠的原、燃料烘干提供了一種較理想的烘干設備。
關鍵詞：回轉式烘干機、套筒式烘干機、節(jié)能
Abstract
The single cylinder type of this text at analyze dryer turns round the foundation exsits the problem is last, introducing a cylinder type turns round the construction characteristics of the dryer with work principle, and according to that machine usage in cement works result, solid measure the data with compute the conclusion, explain that machine to is all a kind of in theories still practice regardless efficiently, the ideal of the economy energy dries the equipments.A cylinder type dryer is an one to pass to the single the dryer of cylinder to change for together of two cylinder or three cylinder , to shorten the shape size of the dryer.When that machine work, the material flows to enter the of cylinder outside the inside one by one in order with the hot air, after dryer inside make" V" or" N" form back and forths fold flow, make use of well the thermal energy dries the material empress unloads again.The dryer's cylinder part inside coat cylinder that place be constituted by two cylinder stalk level, inside is a cylinder , the outside cylinder is for keeping the cylinder , this make the an of the of cylinder got to make use of well, its cylinder shape total length invites 50% － 60% of the very single cylinder , from but significant decrease cover the area to construct the area with the factory premises
Keywords:Turn round the type dryer, set cylinder type dryer, economy
