Description

一种矿用防灭火立式制浆机 技术领域
本发明涉及一种制浆机，具体是一种矿用防灭火立式制浆机。
背景技术
煤矿煤粉自燃现象是导致煤矿火灾的原因之一，解决办法之一就是往煤矿采空区注浆，将煤粉与空气隔绝，解决煤粉自燃的安全隐患。煤矿灌浆防火技术是将黄土或者粉煤灰、尾矿等与水以一定的比例混合，制成均匀的浆液，输送到火灾处理区进行灌浆防火。制浆效果直接影响到防火的可靠性，因此煤矿可靠防火的先决条件就是水和料的充分均匀混合，基于该问题对目前已有的制浆方法存在的缺点做出如下阐述：
申请号为201020597244.X，公告日为2011年9月7日的中国实用新型专利“一体式制浆机”：该设备靠电机驱动滚筒外围的链轮正向旋转采用扬料板组件将黄土颗粒和泥浆提升到高处再落下，通过不断的挤压、摩擦加速颗粒的融解,实现连续搅拌制浆。但该驱动形式受转速限制使制浆机不能很好地将物料与水充分混合。申请号为201220422533.5，公告日为2013年3月20日的中国实用新型专利“煤矿防灭火用滚筒式制浆机”：采用倾斜的容器结构，出浆口用筛体状的圆锥台对较大杂质进行过滤，加强了制浆材料与水的均匀混合，但当浆液较浓或硬颗粒杂质较多时该结构易导致将出浆口被堵。申请号为201130452361.7，公告日为2012年7月4日的中国外观专利“胶体制备机(ZLC-60)”：从图中看出制浆过程采用布满整个制浆容器的滤网，从一定程度上改善了过滤效果，但由于硬颗粒杂质与滤网频繁碰撞摩擦，易造成滤网损坏；同时大面积滤网过滤，一旦滤网被堵塞将难于清洗。申请号为201120469773.6，公告日为2012年7月11日的中国实用新型专利“一种自动排渣式制浆机”：为一种离心制浆法的制浆机，通过高速的制浆叶片混合水与料的同时还将较大的硬质颗粒打碎，实现均匀细腻的浆液制备，但该过程功耗较大，同时当遇到硬度较大的颗粒时很可能将叶片损坏。
发明内容
针对上述现有技术存在的问题，本发明提供一种矿用防灭火立式制浆机，在其内部无需过滤网就可以对制浆过程中的杂质进行过滤，具有制浆均匀、能耗低、排渣效果明显、占地面积小以及使用寿命长。
为了实现上述目的，一种矿用防灭火立式制浆机包括料斗、内筒、外筒、螺旋输送机和搅拌装置，料斗装在内筒顶部，内筒设置在外筒内且内筒底部与外筒底部留有间隙，所述的内筒外沿通过回转支承装在外筒顶部的外沿上，内筒外壁与外筒内壁之间留有间 隙，能使内筒相对外筒旋转，实现了无需过滤网就可以过滤的效果；所述的搅拌装置包括波轮、传动轴和皮带轮，波轮放置在外筒内的底部，所述的外筒底部为与波轮相配合的凹形，波轮通过传动轴与设置在外筒外部的皮带轮连接，所述的传动轴通过轴连接座装在外筒外侧底部，传动轴与外筒之间设有防水密封件；外筒侧壁的上部设有出浆口、下部设有出渣口，螺旋输送机设置在外筒一侧并且其一端与出渣口管路连接，所述的螺旋输送机的出料口与外筒底部的垂直距离大于出浆口与外筒底部的垂直距离，所述内筒内壁的下部设有刮渣板，在刮渣板旋转方向的前侧设有出渣孔。
进一步，还包括注水管，注水管装在内筒顶部；便于物料的进一步混合。
进一步，所述的出浆口外侧设有带有活套的过滤网；增加滤网起到二次过滤的作用，解决了在重力作用下未能沉淀下来的杂质过滤问题。同时滤网采用活套的结构，可以直接插拔，这为更换滤网带来极大的方便，便于工作人员的维修。
进一步，所述的刮渣板为渐开线的形状。这种结构排渣效果好，且使用寿命长。
进一步，所述的波轮采用内部凸起的结构，所述的凸起为S型。该结构通过高速旋转能够很好的将料和水均匀混合，同时根据离心力的作用将将硬质物块以及较大的土块甩到内筒内壁，其中硬质物块将由螺旋输送机排出，而土块将与刮渣板高速碰撞而破碎，再次混合搅拌。
进一步，还包括带有阀门的清洗管道，所述的清洗管道装在外筒底部且与外筒内部贯通。当制浆完毕后在清洗制浆机的过程中，打开清洗管道的阀门，便于让残余在波轮底部的浆液一并排出，能更好的清洗整个制浆机。
与现有技术相比，本发明无需使用扬料板，制浆过程不受转速影响，高速旋转的搅拌装置解决了料和水混合不充分的问题。同时，采用二次过滤——第一次为杂质颗粒沉降，靠内外筒之间的间隙实现无网过滤，第二次为小面积滤网过滤，小滤网采用活动插拔的结构，免去滤网维修的困扰。此外,本发明只对土块进行冲击打撒，不对硬质颗粒进行破碎，能耗得到降低。具体的是采用搅拌和排渣相结合的方式，波轮高速旋转进行制浆搅拌，由于波轮的高速搅拌带来的离心力会使杂质靠近内筒内壁，然后内筒带动刮渣板低速旋转，不断地将硬质颗粒收集到出渣口处实现排渣，这同时给搅拌和排渣带来了双重功效；制浆容积采用内筒和外筒结构内筒和外筒之间的缝隙实现一次过滤，起到无网过滤的效果；同时内筒在该处还起到缓冲浆液及沉淀硬质颗粒的作用；出浆口处采用活套的滤网结构实现二次过滤的作用，降低了以往因滤网堵塞给工人带来的大劳动力检修问题；此外本发明采用立式制浆结构，解决了以往制浆机占地面积较大的缺陷。

具体实施方式
下面结合附图对本发明作进一步说明。
如图1至图3所示，本发明包括料斗1、内筒6、外筒5、螺旋输送机11和搅拌装置，料斗1装在内筒6顶部，内筒6设置在外筒5内且内筒6底部与外筒5底部留有间隙，所述的内筒6外沿通过回转支承3装在外筒5顶部的外沿上，内筒6外壁与外筒5内壁之间留有间隙，能使内筒6相对外筒5旋转；实现了无需过滤网就可以过滤的效果；所述的搅拌装置包括波轮8、传动轴15和皮带轮13，波轮8放置在外筒5内的底部，所述的外筒5底部为凹形与波轮8间隙配合，波轮8通过传动轴15与设置在外筒5外部的皮带轮13连接，所述的传动轴15通过轴连接座装在外筒5外侧底部，传动轴15与外筒5之间设有防水密封件；外筒5侧壁的上部设有出浆口4、下部设有出渣口10，螺旋输送机11设置在外筒5一侧并且其一端与出渣口10管路连接，所述的螺旋输送机11的出料口12与外筒5底部的垂直距离大于出浆口4与外筒5底部的垂直距离，所述内筒6内壁的下部设有刮渣板7，在刮渣板7旋转方向的前侧设有出渣孔16。
进一步，还包括注水管9，注水管9装在内筒6顶部；便于物料的进一步混合。
作为本发明的一种改进，所述的出浆口4外侧设有带有活套的过滤网17；增加过滤网17起到二次过滤的作用，解决了在重力作用下未能沉淀下来的细小杂质的过滤问题。同时过滤网17采用活套的结构，可以直接插拔，这为更换过滤网17带来极大的方便，便于工作人员的维修。
作为本发明的另一种改进，所述的内筒6外壁与外筒5内壁之间的间距可根据实际制浆时采用的原料平均具有的杂质粒径进行间距的设定。这为出浆起到一次过滤的效果且为无网过滤，同时内筒6在这里还起到缓冲的作用，设定间距的杂质由于无法进入内筒6外壁与外筒5内壁之间，受重力的作用将沉于制浆机的底部，通过内筒6旋转带动刮渣板7将这些杂质排到螺旋输送机11，由螺旋输送机11排出制浆机。
作为本发明的一种改进，所述的刮渣板7为渐开线的形状。这种结构排渣效果好，且使用寿命长。
进一步，所述的波轮8采用内部凸起的结构，所述的凸起为S型。该结构通过高速旋转能够很好的将料和水均匀混合，同时根据离心力的作用将将硬质物块以及较大的土块甩到内筒6内壁，其中硬质物块将由螺旋输送机11排出，而土块将与刮渣板7高速碰撞而破碎，再次混合搅拌。
进一步，还包括带有阀门的清洗管道14，所述的清洗管道14装在外筒5底部且与外筒5内部贯通。当制浆完毕后在清洗制浆机的过程中，打开清洗管道14的阀门，便于让残余在波轮8底部的浆液一并排出，能更好的清洗整个制浆机，清洗完成后将清洗管道14阀门关闭，保证制浆时的密封性。
制浆开始时，通过电机带动皮带轮13开始转动，皮带轮13通过传动轴15带动波轮8开始转动，当波轮8转动一段时间之后,经调节好比例的制浆原料通过料斗1和注水管9进入到内筒6中，开始制浆；同时通过中控齿轮2转动带动回转支承3转动，进而带动内筒6进行低速旋转进行排渣工作。制浆过程中，随着液位的升高，浆液从内筒6与外筒5之间的间隙向上传送，由于内筒6外壁与外筒5内壁之间的间距小于杂质的平均粒径，故只有在这个粒径范围内的杂物颗粒会随着浆液进入内筒6与外筒5之间，并通过出浆口出浆，在出浆口4处通过过滤网17可进行二次过滤，进一步降低输出浆液的杂质含有量；被沉淀的杂质由于刮渣板7及出渣孔16的作用，通过出渣口10进入螺旋输送机11，并通过螺旋输送机11排出。在制浆刚开始时，为延长制浆机的使用寿命因防止搅拌干料的现象，在制浆刚开始时应保证底部充满水后再启动给料机，由于制浆量较大，因此此时的水料比误差可以忽略不计。
