Description

一种烘丝机 技术领域
本发明涉及烟丝干燥设备技术领域，尤其是涉及一种烘丝机。
背景技术
烟草行业现有技术中，滚筒式烘丝机的滚筒输入端设置两个通道，进料装置通过其中一个通道将烟丝直接输送进滚筒内，工艺风输送管道通过另一个通道将工艺风直接输送进滚筒内，烟丝与工艺风在滚筒内汇合进行热交换，从而使烟丝干燥，完成烘丝工作。
烟丝与工艺风分别进入滚筒内，在输入端烟丝无法有效利用工艺风充分松散开，甚至有可能在输入端堆积，造成部分烟丝干燥不均匀的现象。
现有技术中烘丝机大多采用蒸汽为热源，将预先预热和填加水分的烟丝通过由蒸汽加热的滚筒的旋转输送并在其中被加热，使烟丝水分在较低的温度下缓慢汽化，从而生产出合格的烟丝。此种烟丝出口水分虽均匀、稳定，但由于输送烟丝速度较慢，因此膨胀率较低，烟丝造碎较大，且有“干头干尾”现象。
因此，现有技术中烘丝机的滚筒一般设置耙钉、或者抄板、或者同时设置耙钉和抄板，以实现抛料。滚筒按一定转速转动运行，耙钉或抄板在滚筒的带动下把物料扬起抛落，形成物料帘，由于耙钉或抄板的形状一致，滚筒旋转过程中，各耙钉或各抄板均把物料运转到相同的高度落下，形成的物料帘在滚筒横截面上的面积比较小(参阅图12)，物料无法充分散开，导致物料与滚筒中的热风的接触面积小，影响烘丝效率和质量。
有鉴于此特提出本发明。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对实施例中的技术方案进行清楚、完整地描述，以下实施例用于说明本发明，但不用来限制本发明的范围。
在本发明的描述中，需要说明的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。

作为一种实施方案，如图1和图3所示，本发明提供一种烘丝机，包括滚筒1、工艺风输送管道2和进料装置3，工艺风输送管道2与滚筒1连通，进料装置3与工艺风输送管道2连通。
具体的，如图1、图3和图4所示，工艺风输送管道2一端与加热装置11连通，另一端与滚筒1连通并从滚筒1输入端伸入滚筒1内，工艺风输送管道2与滚筒1之间设置密封装置，确保滚筒1旋转过程中，工艺风输送管道2与滚筒1仍然密封连接，减少工艺风的泄漏，优选工艺风输送管道2的中心轴线与滚筒1中心轴线重合。
进料装置3靠近滚筒1输入端，包括相互连通的进料机构31和导料机构32，进料机构31位于工艺风输送管道2上方，导料机构32沿与工艺风输送管道2轴向相交的方向延伸，至少部分位于工艺风输送管道2内，导料机构32与工艺风输送管道2内部相通，导料机构32下端与工艺风输送管道2内底壁之间具有高度差；延伸在工艺风输送管道2内的导料机构32上设置有沿工艺风输送方向贯穿导料机构32的通风孔324；导料机构32与工艺风输送管道2相交于工艺风输送管道2上端内壁，且自相交处向下延伸至工艺风输送管道2下端内壁，位于工艺风输送管道2上端范围内的导料机构32的通风孔324的孔径，不大于位于工艺风输送管道2下端范围内的导料机构32的通风孔324的孔径。
进料机构31包括上下设置相互连通的进料罩311和进料气锁312，进料罩311侧部设置有进料口3111，物料通过进料口3111被输送到进料罩311内，工艺风输送管道2上端设有开口，一段进料管33与工艺风输送管道2连接于该开口处，通过该段进料管33，进料气锁312与工艺风输送管道2连通，导料机构32沿着工艺风输送管道2的开口设置并从上往下插入工艺风输送管道2内，导料机构32的下端与工艺风输送管道2下端内壁相交，相交处与工艺风输送管道2内壁最低点具有一定距离，工艺风不仅从导料机构32上的通风孔324通过，也从相交处至工艺风输送管道2内壁最低点之间通过，从而与物料混合并将物料吹散。
作为替代方案，进料机构31的进料气锁312也可设置为其他同时具有落料功能和密封效果的结构。
导料机构32为与工艺风输送管道2相通的结构，则可设置为下端具有出口的管道，也可设置为朝向工艺风输送管道2输送方向一侧为敞口的结构，甚至可设置为一块与工艺风输送管道2上下端内壁相交的导料板，只要能将物料输送至工艺风输送管道2内与工艺风混合即可。本发明中，导料机构32在工艺风输送管道2横截面的投影与工艺风输送管道2内侧壁之间具有间隙，优选方案为投影呈对称分布，工艺风输送管道2的轴截面为对称面。如图5所示，导料机构32在工艺风输送管道2横截面的投影为多边形，包括弧形段和三条直边，其中三条直边均与工艺风输送管道2内壁形成间隙，工艺风可从这些间隙通过；相对的两条直边以工艺风输送管道2的垂直轴截面为对称面对称分布。
导料机构32包括依次连接的第一导料板321、第二导料板322和第三导料板323，第一导料板321和第三导料板323均朝向第二导料板322，第二导料板322自工艺风输 送管道2上端内壁向下延伸至工艺风输送管道2下端内壁，第一导料板321、第二导料板322和第三导料板323组成开口朝向工艺风输送方向的类C型导料机构32，第一导料板321和第三导料板323以工艺风输送管道2的垂直轴截面为对称面对称设置于第二导料板322两侧。第二导料板322上端的宽度大于下端的宽度。
具体的，如图6所示，第二导料板322自工艺风输送管道2上端开口向下延伸，并与工艺风输送管道2下端内壁相交于两点，与工艺风输送管道2内壁最低点形成间隙，第一导料板321和第三导料板323也自工艺风输送管道2上端开口向下延伸，并各自与工艺风输送管道2下端内壁相交于一点，与工艺风输送管道2内壁最低点形成间隙，对称分布于第二导料板322两侧，对称面为工艺风输送管道2的垂直轴截面，且第一导料板321和第三导料板323均朝向第二导料板322，使得第一导料板321、第二导料板322和第三导料板323组成开口朝向工艺风输送方向的类C型导料机构32。
作为替代方案，第一导料板321和第三导料板323可各自与工艺风输送管道2下端内壁相交于两点，或者，第一导料板321和第三导料板323与工艺风输送管道2上端和/或下端不相交。
第二导料板322上设置供工艺风通过的通风孔324，其中，分布在第二导料板322上端的通风孔324的孔径不大于分布在第二导料板322下端的通风孔324的孔径。如图5和图6所示，第二导料板322上均匀布满了通风孔324，分布于上端的通风孔324的孔径较小，分布于下端的通风孔324的孔径较大。
作为替代方案，第二导料板322上的通风孔324，孔径大小均相等。第一导料板321和第三导料板323可设置通风孔324也可不设置通风孔324，优选方案为不设置通风孔324。
在本方案中，物料输送装置将物料从进料口3111输送到进料罩311内，物料经过进料气锁312落到导料机构32上，从导料机构32通风孔324及导料机构32与工艺风输送管道2之间的间隙通过的工艺风将物料吹散，使物料与工艺风在工艺风输送管道2内充分混合后再进入滚筒1内。
进料装置3与工艺风输送管道2连通，使得物料在工艺风输送管道2内与工艺风汇合，从而使工艺风与物料充分接触，提高物料松散度，同时，物料在进入滚筒1前即被工艺风提前预热干燥，提高烘干效率，提高工艺风的干燥效果。
导料机构32下端与工艺风输送管道2内底壁之间具有高度差，使导料机构32与工 艺风输送管道2内部相通且使工艺风从导料机构32与工艺风输送管道2内底壁之间的间隙通过，使得导料机构32即使是管道结构仍然能使物料在工艺风输送管道2内与工艺风混合，提高物料松散度。
导料机构32上设置有沿工艺风输送方向贯穿导料机构32的通风孔324，从通风孔324通过的工艺风和从导料机构32与工艺风输送管道2之间的间隙通过的工艺风配合，使得物料松散得更好。
导料机构32在工艺风输送管道2横截面的投影与工艺风输送管道2内侧壁之间具有间隙，且以工艺风输送管道2的垂直轴截面为对称面对称设置，使得工艺风可均匀作用于物料，从而使物料在工艺风输送管道2内均匀散开，进而被均匀输送到滚筒1中被均匀加热，避免出现滚筒1内各处的物料密度不一而导致部分物料干燥不足部分物料干燥过度的情况。
第一导料板321、第二导料板322和第三导料板323组成开口朝向工艺风输送方向的类C型导料机构32，使得物料沿着工艺风输送方向前进，避免从第二导料板322两侧掉落到第二导料板322朝向工艺风输送反方向的一侧而造成物料堆积堵塞工艺风输送管道2。
第一导料板321、第二导料板322和第三导料板323均与工艺风输送管道2下端内壁最低点形成间隙，工艺风可从间隙通过，使得从导料板落下的物料被顺利往前输送，避免在工艺风输送管道2下端内壁最低点附近形成堆积。
第一导料板321和第三导料板323上没有设置通风孔324，避免工艺风在类C型范围内形成对流，影响物料的输送。
第二导料板322上均匀设置通风孔324，工艺风从通风孔324通过将物料吹散并往前输送，使得物料松散得更充分，而分布在上端的通风孔324比分布在下端的通风孔324小，可削弱物料自身重量的影响，使物料在工艺风输送管道2中均匀松散开。
第二导料板322上端的宽度大于下端的宽度，使得上端面积大于下端面积，与分布于各自上的孔径不同的通风孔324配合，也在一定程度上削弱物料自身重量的影响，使得物料充分松散开。

作为一种实施方案，本发明提供一种烘丝机，包括滚筒1，滚筒1包括筒体和加热部件，加热部件包括弧形加热器14。
如图10和图11所示，筒体下方设有弧形加热器14，弧形加热器14安装在支撑筒体的支架10上，通过热辐射非接触加热筒体。
筒体的外壁与弧形加热器14的内侧之间具有50～150mm的间隙，在非接触的同时，达到理想的加热效果。

在筒体和弧形加热器14构成的加热功能滚筒1的外围设有保温罩(图中未示出)，可以是以保温腔或其他形式将筒体和弧形加热器14罩设在内部，具有保温和防止热量散失的作用。
在本方案中，弧形加热器14通过热辐射加热筒体，由于筒体旋转，所以整个筒体均匀受热，进而加热烘干物料，同时，通入热风，起到辅助加热的作用，保温罩具有保温和防止热量散失的作用。
作为一种实施方案，本发明提供一种烘丝机，包括滚筒1，滚筒1包括筒体和加热部件，加热部件包括PTC加热片。
在筒体的内壁上，和/或抄板4上，和/或筒体的外壁上安装PTC加热片，通过热辐射加热筒体。
PTC加热片的形状可控，满足多种安装和排布方式，且PTC加热片还具有过热保护的作用，防止温度过热造成物料质量受损、设备受损以及能量损失等。
作为一种实施方案，如图14所示，本发明提供一种烘丝机，包括筒体和沿筒体轴向设置于筒体内壁的抄板4，抄板4设有至少两种，包括第一抄板41和第二抄板42，第一抄板41和第二抄板42结构不同。
具体的，烘丝机筒体内壁上分布着若干抄板4，这些抄板4沿筒体轴向设置，至少包括两种不同结构，这两种具有不同结构的抄板4为第一抄板41和第二抄板42。抄板4一端安装于筒体内壁，另一端向筒体中心延伸，延伸的一端处于同一圆周上。本发明中，沿筒体周向依次间隔交替设置结构不同的抄板4。第一抄板41和第二抄板42延伸的一端具有不同结构，如，第一抄板41为平直板，第二抄板42为弯折板，平直板延伸的一端弯折形成弯折板，平直板和弯折板沿同一圆周依次间隔交替分布于筒体内壁上，远离筒体内壁的第一抄板41端部和第二抄板42端部处于同一圆周上，即，第一抄板41和第二抄板42距离筒体内壁的径向距离相等，也就是说抄板4的高度相等，抄板4的 高度根据实际需要设置。相较于平直板，弯折板将物料运转到更高处才开始落下，如此，周向上相邻的平直板和弯折板将物料运转到不同的高度落下，在筒体横截面所在平面上形成比较大的物料帘(参阅图13)，使物料分散得比较充分，因筒体中的热风沿筒体轴向吹送，从而使物料与热风的接触面积增加，进而提高物料的烘干效率。而各抄板4延伸的一端处于同一圆周上，使得相同周向上的抄板4所运转的物料在落下的过程中不会碰撞在一起，减少造碎。另外，加工过程中，也能提高喷射料液的效率，如，对物料进行加香时需要喷射香料，因物料帘面积比较大而增加了香料与物料的接触面积，进而提高加工效率。
如图15所示，每块抄板4并没有沿轴向贯穿筒体，每块抄板4可根据需要设置成一定的长度，两块及以上的抄板4长度之和与筒体的长度相等。本发明的实施方案中，筒体内壁沿轴向设置有至少两段安装区间，每段安装区间沿筒体周向安装有若干抄板4，包括第一抄板41和第二抄板42。同一结构的抄板4沿筒体轴向呈螺旋阶梯状排布。如此，同一时刻，相邻安装区间的同一种抄板4，各自所运转物料落下时所形成的物料帘，并不完全重叠，从而使得物料更充分地散开在筒体内，进而充分利用筒体中的热风进行干燥，提高烘干效率。同一圆周上，各抄板4均匀设置于筒体内壁上，使得相同圆周上的抄板4所运转物料落下时相互的间隙比较均匀，利于筒内热风的吹送，从而使物料均匀地烘干。
相邻的两段安装区间部分区域重叠，或者相隔具有间隙，位于两安装区间内的抄板4在筒体中心轴上的投影相交或具有间隙。当位于两安装区间内的抄板4在筒体轴线上的投影相交，包括投影相接和具有重叠部分两种情况，可使物料在筒体内占据的空间更大，从而更充分地利用热风，提高烘干效率。当位于两安装区间内的抄板4在筒体轴线上的投影具有间隙，轴向上相邻的两抄板4各自所运转的物料在落下的过程中不会碰撞在一起，减少造碎。
相邻两段安装区间内的抄板4交错布置，位于筒体轴向上的不同直线上，如，轴向上相邻的第一抄板41和第二抄板42位于筒体轴向上的不同直线上。如此，相较于第一抄板41和第二抄板42位于轴向上的同一直线上，第一抄板41和第二抄板42位于筒体轴向上的不同直线上，所运转的物料从高处落下时在筒体内占据的空间更大，从而可更充分地利用热风，提高烘干效率。
抄板4还包括第三抄板43，其中第一抄板41为平直板，第二抄板42和第三抄板 43为结构不同的弯折板，第二抄板42和第三抄板43均包括自筒体内壁向筒体中心延伸的一段平直部，在筒体周向上，第一抄板41、第二抄板42和第三抄板43依次间隔设置。
具体的，如图14至图17所示，第一抄板41为平直板；第二抄板42由平直部和一个弯折部形成，第二抄板平直部421一端与筒体内壁连接，另一端沿筒体旋转方向弯折形成第二抄板弯折部422；第三抄板43由平直部和两个弯折部形成，第三抄板平直部431一端与筒体内壁连接，另一端连续弯折形成具有两个弯折部的第三抄板弯折部432，所形成的两个弯折部朝向筒体旋转方向；其中，平直部沿径向的长度不小于平直板沿径向的长度的一半。第一抄板41、第二抄板42和第三抄板43沿周向上依次均匀设置，将物料运转到不同的高度落下，形成比较大的物料帘，使物料与热风的接触面积增加，进而提高物料的烘干效率。平直部沿径向的长度比较长，弯折部比较短，尤其是第三抄板43的两个弯折部，各弯折部沿径向的长度均较短，确保把物料运转到更高的高度再落下的同时，还保证物料可从弯折部顺利落下，避免弯折部过长而裹住物料导致物料无法散开，影响烘干效果。
本发明的滚筒1和抄板4，适用于薄板式烘丝机，也适用于管板式烘丝机。
作为一种实施方案，如图1和图2所示，本发明提供一种烘丝机。
滚筒1的输出端连通有出料罩5，该出料罩5的下端设有与其连通的出料气锁6。出料罩5的上端与回风管道7的第一回风管道71的一端连通，另一端连通旋风分离器72。主工艺风机74通过第二回风管道73与旋风分离器72连通。第三回风管道75连通主工艺风机74及加热装置11，第三回风管道75的支路连通工艺风输送管道2。
在本方案中，物料从进料口3111进入烘丝机，经进料气锁312内的蒸汽膨胀，从进料管33进入工艺风输送管道2，与加热装置11加热并通过工艺风输送管道2输送的热风混合，进入滚筒1内，在不超过2米/秒的风速的顺向高温气流作用、滚筒1本身的加热和旋转共同作用下，物料被干燥膨胀，并通过与滚筒1连通的出料罩5及出料气锁6输出。
与物料进行热交换后的气体则通过与出料罩5上部连通的第一回风管道71、旋风分离器72、第二回风管道73、主工艺风机74、第三回风管道75，一部分直接进入加热装置11进行循环加热，另一部分通过第三回风管道75的支路进入与加热装置11出口连通的工艺风输送管道2中，快速调节热风温度，达到适宜的烘丝温度，获得干燥物料所需的热风温度，即干燥物料的温度。物料从进料气锁312进入到出料气锁6出料，是在 一个密闭的通道里输送，降低了热量损失，从而节约了能源。热气流与物料混合后的气体由旋风分离器72进行除尘。
另外，第二回风管道73上设置风量检测装置，以检测系统管道内的风量及风速，进行系统风量的控制，保证系统的质量平衡。
第三回风管道75的支路上设置调节风门76，以快速调节热风温度。
工艺风输送管道2靠近进料气锁312的位置上设置温度传感器21，对热风温度进行检测与控制。
工艺风输送管道2靠近加热装置11出口端设置控制水装置22，精确调节物料出口的含水率。
主工艺风机74的出口端设置排潮机77和排潮口78，通过排潮量的调节能实现系统的压力平衡稳定。
出料罩5与第一回风管道71之间连通支路，支路上设有补新风调节风门8和补新风加热器9，通过补新风调节风门8控制往回风管道7内吸风的量，并通过补新风加热器9对热风及吸入的风加热，平衡系统内的循环风压。
本发明还可以根据实际工艺需要调整烘丝机设备参数，不限于以下实施方案：
作为一种实施方案，可以关闭滚筒1的加热部件，关闭气流式系统，完全利用滚筒1加热风烘干，相当于传统的滚筒式烘丝机。
作为一种实施方案，可以关闭滚筒1的加热部件，完全用热风吹干，相当于传统的滚筒式烘丝机与气流式烘丝机的结合。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
