1、本发明通过设置主动齿轮和从动齿轮，第一电机带动主动齿轮转动，由于主动齿轮和从动齿轮啮合，从动齿轮转动，与从动齿轮固定连接的回转窑体转动，由于回转窑体本身是斜向设置，同时回转窑体转动，使得物料边转动边从回转窑体的首端向燃烧器一端移动，物料越靠近燃烧器一端温度越高，物料逐渐被烧嘴喷出的火焰均匀培烧，焙烧效果更好，降低焙烧能耗。
2、本发明通过设置旋流板，煤粉燃烧的火焰通过燃烧器一端的烧嘴喷出，由于烧嘴内部设置有若干个旋流板，使得火焰喷向被分散呈散射状向回转窑体内部各处喷射，火焰喷出的高温区扩大，提高培砂还原度，降低冶炼成本。
3、本发明通过设置转轮，第二电机带动转轮转动，由于转轮的四侧开设有扇形槽，煤粉从进料斗落入扇形槽，转轮转动时，扇形槽内的煤粉转动至下方，落入进煤斗下方，通过改变转轮转速，扇形槽内接收的煤粉量随之改变，可以改变转轮上的扇形槽输送的煤粉量，从而改变气流中煤粉的浓度，从而控制焙烧火焰的强度。
本发明通过设置震动机构，利用震动机构带动滤网震动，尺寸合格的物料通过滤网出料，大于滤网孔隙的物料留在滤网上，保证物料的质量，通过扭转转把，可以带动出料斗转动，使得出料斗倾斜，出料斗内部滤网上的不合格物料会滚动滑出出料斗，对不合格物料进行收集，避免滤网的网孔被堆积的不合格物料堵塞。

在下文的描述中，给出了大量具体的细节以便提供对本发明更为彻底的理解。然而，对于本领域技术人员而言显而易见的是，本发明可以无需一个或多个这些细节而得以实施。在其他的例子中，为了避免与本发明发生混淆，对于本领域公知的一些技术特征未进行描述。
请参阅图1、图3-5，本实施例提供了一种回转窑焙烧结构及其培烧工艺，包括底板1，底板1上方设置有回转窑体2，回转窑体2下方一侧设置有第一电机4，第一电机4的输出端固定连接有主动齿轮5，回转窑体2中部固定连接有从动齿轮6，底板1上端中部固定连接有固定板3，固定板3一侧通过固定座固定连接有第一电机4，主动齿轮5上侧与从动齿轮6啮合连接，首先打开第一电机4，第一电机4的输出轴转动时，带动主动齿轮5转动，由于主动齿轮5和从动齿轮6啮合，使得从动齿轮6转动，带动与从动齿轮6固定连接的回转窑体2转动，回转窑体2的两端均连接有轴承座24，回转窑体2的两端分别与两个轴承座24转动连接，轴承座24下端均固定连接于底板1上端，回转窑体2的两端转动连接于两个轴承座24之间，轴承座24起到支撑作用，使得回转窑体2的两端更加稳固，连接管8上端中部固定连接有进煤斗10，第一固定架22上端远离鼓风机20一侧固定连接有四个第一连接杆21，四个第一连接杆21的上端分别固定连接于进煤斗10的四侧表面，进煤斗10被四个第一连接杆21固定，十分稳固，焙烧前，向进煤斗10中注入煤粉，进煤斗10内部设置有转轮11，转轮11四侧均开设有扇形槽，转轮11转动连接于进煤斗10内部之间，转轮11的扇形槽的半径大于进料斗23的底端直径，转轮11一端通过中轴贯穿进煤斗10一侧侧壁且固定连接有第二电机12，打开第二电机12带动转轮11转动，由于转轮11的四侧开设有扇形槽，煤粉从进料斗23落入其中一个扇形槽，转轮11转动时，扇形槽内的煤粉转动至下方，扇形槽输送的物料由于自身重力作用，落入进煤斗10下方，通过改变转轮11转速，扇形槽内接收的煤粉量随之改变，可以改变转轮11上的扇形槽输送的煤粉量，然后煤粉由进煤斗10落入连接管8中。
在进一步的实施例中，进煤斗10一侧设置有鼓风机20，连接管8远离燃烧器71一端与鼓风机20固定连接，回转窑体2一端连接有喷煤机构7，喷煤机构7包括燃烧器71，回转窑体2一端与燃烧器71中部转动连接，燃烧器71远离回转窑体2一端固定连接有连接管8，燃烧器71一端贯穿回转窑体2且固定连接有烧嘴72，烧嘴72中部四侧固定连接有若干个旋流板73，底板1上端靠近鼓风机20一端固定连接有第一固定架22，鼓风机20固定连接于第一固定架22上端，鼓风机20固定在第一固定架22上端使得鼓风机20与连接管8在同一水平线上，通风效果更好，打开鼓风机20，鼓风机20将外部的气流吸入，向连接管8内通入气流，气流推动连接管8内的物料进入燃烧器71中，燃烧器71内的气流和可燃煤粉混合燃烧，煤粉燃烧的火焰通过燃烧器71一端的烧嘴72喷出，由于烧嘴72内部设置有若干个旋流板73，使得火焰喷向被分散呈散射状向回转窑体2内部各处喷射，使得火焰喷出的高温区扩大，回转窑体2远离鼓风机20一侧设置有原料斗9，底板1上端远离第一连接杆21一端固定连接有第二固定架26，第二固定架26的上端固定连接有四个第二连接杆27，四个第二连接杆27上端分别固定连接于原料斗9的四侧表面，原料斗9被四个第二连接杆27固定，更加稳固，此时将待焙烧的物料倒入原料斗9中，原料斗9的底端固定连接有进料管25，进料管25远离原料斗9一端转动连接于回转窑体2的端部，物料经过原料斗9进入进料管25中，进料管25的下端呈倾斜设置，方便物料从进料管25滑落，避免物料堵塞在进料管25中，物料进入回转窑体2一端后，由于回转窑体2本身是斜向设置，同时回转窑体2转动，使得物料边转动边从回转窑体2的首端向燃烧器71一端移动，物料逐渐被烧嘴72喷出的火焰均匀培烧。
参阅图2、图6，在实施例1的基础上作出的进一步改进：回转窑体2靠近燃烧器71一端的下方设置有出料斗13，回转窑体2相对出料斗13开设有出料孔，物料移动至回转窑体2的出料孔处，由于自身重力作用从出料孔下落，物料落入下方相对的出料斗13内，出料斗13中部设置有滤网15，滤网15四侧固定连接有侧框17，物料落在出料斗13内的滤网15上，滤网15起到筛分的作用，尺寸合格的物料通过滤网15出料，大于滤网15孔隙的物料留在滤网15上，滤网15的下方设置有震动机构16，震动机构16包括凸轮162，两个凸轮162中部固定连接有连接轴161，两个凸轮162分别设置于侧框17下端两侧，连接轴161一端固定连接于第三电机163的输出轴，第三电机163通过固定座固定连接于出料斗13的侧壁，连接轴161远离第三电机163一端通过轴承转动连接于出料斗13内壁，打开第三电机163，第三电机163的输出轴转动带动连接轴161转动，使得连接轴161上的两个凸轮162转动，凸轮162的凸出端转动至接触滤网15的侧框17时，侧框17被顶起，凸轮162的凸出端转动至远离滤网15的侧框17时，侧框17下移，随着凸轮162的往复转动，侧框17上下移动带动滤网15上的物料震动，使得物料被震动筛分，避免物料堆积在滤网15上导致筛分效果不好。
在进一步的实施例中，出料斗13的内壁两侧均开设有侧槽19，侧槽19的上端槽壁均固定连接有弹簧18，两个弹簧18分别固定连接于侧框17的上端两侧，在侧框17被凸轮162顶起上移时，侧框17两端连接的弹簧18被侧框17压缩，当凸轮162的凸出端不与侧框17接触时，侧框17不受凸轮162的推力，弹簧18回弹产生的张力推动侧框17下移复位，使得侧框17始终与凸轮162表面接触，侧框17上下移动时更加稳定。
出料斗13两侧设置有侧杆14，侧杆14均固定连接于底板1上端，出料斗13转动连接于两个侧杆14之间，所述出料斗（13）一侧设置有转把28，出料斗13一侧侧壁中部通过中轴贯穿其中一个侧杆14且与转把28固定连接，出料斗13与转把28相连接，通过扭转转把28，可以带动出料斗13转动，使得出料斗13的角度改变，出料斗13的顶端倾斜至一定角度时，出料斗13内部滤网15上的不合格物料会滚动滑出出料斗13，即可对不合格物料进行收集，避免滤网15的网孔被堆积的不合格物料堵塞。
