摘要：目前，機立窯存在著很多的問題。這些初級階段的立窯裝備老化、不完善，工藝落後，消耗大，成本高，生產不穩定，產量質量低，它們正處於被淘汰的處境。因此，新型的JLY3809機立窯應運而生。而窯體及卸料裝置的結構的好壞決定了此機立窯總體結構的好壞。JLY3809機立窯從以下方面對窯體及卸料裝置方面進行了改造。1.大膽地的對原有機立窯進行了擴徑改造，實現對立窯產量的大幅度提高。2.窯體保溫直接影響機立窯產、質量，由於窯體保溫不好，配煤增加，中部熱量過剩，造成中部煅燒帶延長，底火下移，影響機立窯煅燒，產量降低。故本機立窯在窯體內採用了絕熱保溫效果好的新型保溫材料和澆注料。3. 選用新型窯體卸料結構。本機立窯不宜採用塔式結構，因為塔式結構不僅增加卸料部分高度，縮短窯的有效高度；而且隨著窯徑擴大，塔式窯中、邊部卸料能力不均勻性越大，造成中部卸料速度遠遠大於邊部卸料速度，必然造成底火拉深，中風不足，故我選擇了卸料均勻性好的雙曲面可換齒高效節能塔篦。經過對窯體及其卸料裝置這一系列的結構和技術的改造，JLY3809機立窯的能耗變低，水泥產質量都得到了提高。

he design of the JLY3809 machine sign kiln (the kiln body and unload to anticipate a parts)
Abstract： Currently, the machine signs kiln exists a lot of questions. Such as material aging, not perfect, the craft falling behind, consuming greatly, high cost, unsteady production, and low output mass in these entrlevel step’s sign kilns. They are placed in elimination of circumstances. Therefore, the JLY3809 machineses of the new model sign kiln emerge with the tide of the times. But the quality of the kiln body and unload apparatus comes to a decision of the quality of this machine signs kiln total structure. The kiln body and unloaded apparatus of the JLY3809 machineses sign kiln are carried on a reformation from the following aspects. 1.The diameter reformation is carried on to expand bravely in the original machine signed kiln. Then the kiln output of significant exaltation is realized. 2. The kiln body heat preservation will effect the production and quality directly. Because the kiln body heat preservation is not good. The mass of the coal will increase. The central calorific value will excess. These will result in that the central burning strap extends and the bed fire descends to move. 3.Unload to anticipate structure is chosen with the new kiln body. This machine's signing kiln should not adopt the tower type structure, because the tower type structure not only increases the division height, but also shortens the burden height of the kiln. And with the kiln diameter magnification, in the tower type kiln, the ability of anticipate asymmetry of the side unload unit is bigger, this results in that the speed of the central part of the unload apparatus is far larger than the speed of the side unit. It makes the bed fire tractive by all means deep and the middle wind suffers shortage. So energy tower with a good double of even curved faces is chosen, so that tooth can be changed. In addition, the energy tower is economical and efficient. Passed by a reformation of the kiln body and a series of structures and technologies of unload apparatus, Consumption of JLY3809 machineses' signing kiln can be become low, and the cement produces masses can get an exaltation.
