矿井立式磁悬浮鼓风机装置 技术领域
[根据细则91更正 19.12.2019]　
本申请涉及矿井立式磁悬浮鼓风机装置。
背景技术
目前，矿井用轴流通风机的动叶调节机构主要是停车可调式动叶调节装置。该装置主要由调节长轴、涡轮箱、中心直齿轮、伞齿轮、叶柄齿轮、叶柄铜套、窥视窗等零件组成。当风机需要调整工况时，首先必须将风机停转，然后用调节长轴伸入机壳内部，对准涡轮箱调节口，通过调节涡轮箱由蜗杆带动伞齿轮，由伞齿轮带动叶柄齿轮，从而实现动叶角度的调节。
该调节装置在生产、使用过程中，存在以下缺陷：
1.由加工精度所导致的动叶同步性问题。
由于该装置主要是依靠一个大的伞尺寸带动16或者20个小的叶柄伞齿轮来实现动叶调节。因此为保证动叶角度调整的同步性，在风机生产过程中对于叶柄伞齿轮有着极高的精度要求，所以不可避免的会有若干动叶发生同步性较差的情况。
2.必须停车后才可进行动叶角度的调节。
该装置在调节动叶时必须将调节长轴伸入机壳内部，对准位于叶轮外壳上的涡轮箱调节口，在风机运行时是无法进行动叶角度调节的。
3.调节困难
对于矿井通风机来说，一般多为大流量小压力的叶型，因此该系列风机动叶普遍偏长，从而导致该装置的调节长轴过长较难对准涡轮箱调节口。
4.角度调整精度较差
该装置的动叶角度调节反馈需要从机壳上的窥视孔观察，通过刻度线以动叶尾部作为指针来判断动叶当前角度。因此角度调整精度较差。
5.必须现场调节
由于该装置为纯机械结构，因此无法实现远程控制。
CN201220121548.8用于矿井风机的液压动叶调节装置虽然提供一种风机方案，但是还是无法解决现有风机的缺陷。

在进风口12的下方15cm处通过三根直径1cm、长25cm的钢制的支架11，将一个外径10cm、内径9.5cm、高2cm的钢制圆环30固定在外筒1的内壁上，支架11、圆环30所在的平面与外筒1的筒壁垂直。在圆环30的内部固定安装一个外径9.5cm、内径9cm、高2cm的橡胶圈31，在橡胶圈31内部固定安装一 个外径9cm、内径5cm、高2cm的第一磁铁圈5，通过橡胶圈31的缓冲作用，第一磁铁圈5被支架11和圆环30牢牢地固定在外筒1的内壁上。在第一磁铁圈5的正上方2cm处设置一个外径9cm、内径5cm、高2cm的第二磁铁3，第二磁铁3与第一磁铁圈5的相互排斥。在第一磁铁圈5的正下方2cm处设置一个外径9cm内径5cm高2cm的第三磁铁7，第三磁铁7与第一磁铁圈5的相互排斥。在第二磁铁3的内部固定安装一个外径5cm、高2cm第二橡胶环4，在第二橡胶环4的正上方安装一个外径9cm、高6cm的钢制的锥形帽2，锥形帽2的外边缘恰好与第二磁铁3的外边缘吻合。锥形帽2的作用是减少进风阻力。在第三磁铁7的内部固定安装一个外径5cm、高2cm的第三橡胶环33。在第二橡胶环4的下方圆心位置处固定安装直径1cm、长70cm的钢制主轴6。在主轴6与第一磁铁圈5水平位置处固定安装一个外径3cm、高2cm的第四磁铁32，第四磁铁32与第一磁铁圈5相互排斥。主轴6从第三橡胶环33中间穿过并相互固定。当主轴6转动时能够带动第二磁铁3和第三磁铁7转动。在第二磁铁3与第一磁铁圈5、第一磁铁圈5与第三磁铁7之间的相互排斥作用下，主轴6在垂直方向上的位置相对固定，不会在垂直方向上大幅度升降。在第四磁铁32与第一磁铁圈5之间的相互排斥作用下，主轴6在水平方向上的位置相对固定，不会在水平方向上大幅度摇摆。在进风口12的下方20cm处的外筒1内壁上安装一圈钢制的导风板13，导风板13的横截面呈钝角三角形，导风板13横截面的底边长8cm、高2.5cm，导风板13横截面的最小锐角位于上方，从而导向效果好。在导风板13下方5cm处的主轴6上固定安装三片长轴25cm的类椭圆形钢制叶片14，当叶片14顺时针转动时，可以推动空气向下运动。在进风口12的下方70cm处通过三根直径1cm长20cm的钢制固定杆17，将一个外径20cm、内径19cm高10cm的钢制圆筒22固定在外筒1的内壁上，固定杆17、圆筒22所在的平面与外筒1的筒壁垂直。在圆筒22的内壁上固定安装十二块长4cm、宽3cm、高10cm的第五磁铁片15，第五磁铁片15在圆筒22的内壁上均匀排列，第五磁铁片15的N极都指向主轴6。在圆筒22的正上方安装一个外径20cm高8cm的钢制的导风锥16，导风锥16的外边缘恰好与圆筒22的外边缘吻合。在导风锥16的中心位置处开设一个直径1.5cm的通道37，主轴6穿过通道37进入圆筒22内部。在圆筒22内部的主轴6上固定安装一个直径10cm、高9cm的钢制转子8，在转 子8上有规律性的缠绕上三个线圈9，两个相邻的线圈9之间的夹角为120°。在圆筒22的下部边缘处固定安装三根直径0.5cm长7cm的钢制延伸杆23，在延伸杆23的末端固定安装一个外径10cm、内径8cm、高3cm的钢制固定圈18，在固定圈18内部固定安装一个外径8cm内径6cm高3cm的钢制正极环19。在固定圈18和正极环19之间固定设置一圈固定绝缘环34，固定绝缘环34的作用是阻断固定圈18和正极环19之间的电流传递。在正极环19内部的主轴6上固定安装一个外径4cm、高3cm的钢制负极环20，在主轴6和负极环20之间固定设置一圈中间绝缘环35，中间绝缘环35的作用是阻断主轴6和负极环20之间的电流传递。在负极环20上开设两个宽0.5cm的电极缺口24，两个电极缺口24在负极环20的两端，恰好将负极环20分成相同的两段。在正极环19的内部安装两片长4cm高3cm的弧形钢制电刷片25，两个电刷片25在正极环19内部的两端。当主轴6带动负极环20转动时，两个电刷片25一直与不同的负极环20相接触，两个电刷片25不会同时与同一片负极环20接触。将第一导线10与正极环19相连，将两根第二导线36分别与两片负极环20相连。

工作时，接通电源，叶片14开始旋转，带动风从进口连接管26的上开口28进入鼓风机装置，经过加速后，从出口连接管27的下开口29送入出风管。在整个过程中，由于磁铁之间的相互作用，整个装置内部件之间摩擦阻力极小，所以在一定程度上，很大的提高了鼓风机的工作效率。本申请设计合理、成本低廉、结实耐用、安全可靠、操作简单、省时省力、节约资金、结构紧凑且使用方便。
