Description

一种具有导风装置的悬辊磨
技术领域
本实用新型属于悬辊磨粉机技术领域，具体涉及一种具有导风装置的悬辊磨。
背景技术
悬辊磨粉机广泛用于冶金、建材、化工、矿山、高速公路建设、水利水电等行业，对矿产物料进行粉碎制粉加工。悬辊磨粉机主要由主机、分析机、集粉器、风机、管道等部件组成，料仓内合格粒度物料，经给料机连续地送入主机磨粉室内进行研磨，粉磨后的粉体被离心风机吹入磨粉室内的气流带走，经分析机进行分级，符合细度的粉体随气流经管道进入旋风集粉器内，进行分离收集，成品粉体经卸料阀排出，分离后的气流由旋风集粉器上端回风管吸入离心风机。不合格的粉体经分析机分离后被甩向筒壁，沿筒壁落下后重新回到磨机研磨。其中主机由机座、进风蜗壳、筒体、磨辊组件及传动机构等组成，通过机座上的磨环与旋转的磨辊组件挤压与研磨来完成制粉。
在悬辊磨粉机领域，如何有效的增加进风量，提高产量，是一个长久以来的重要课题。为了提高产量，现有技术大多采用提高风机功率的方式。随着进风量的增加，现有结构会造成损耗也增大，且含有粉体的回流气体对进风蜗壳的磨损也越来越严重。也就是说，通常，增大风机功率的同时，其产量与功率之比并没有提高，而且含有粉体的回流气体对进风蜗壳的磨损也很厉害，使蜗壳的使用寿命降低。
实用新型内容
本实用新型的目的是为了解决上述现有技术存在的问题，提供一种具有导风装置的悬辊磨。
为实现上述目的，本实用新型采用如下技术方案：一种具有导风装置的悬辊磨，包括机座和进风蜗壳，机座内沿圆周方向均匀设置有若干个斜向的机座风道立柱，进风蜗壳由蜗壳顶板、蜗壳侧板和蜗壳底板组成，所述进风蜗壳的蜗舌区域设置有风道导风板，风道导风板的前部为圆弧段，后部为平面段，圆弧段和平面段光滑连接。
圆弧段的风道导风板安装在蜗舌区域的蜗壳侧板内侧，平面段的风道导风板安装在进风口区域的机座风道立柱的内侧壁上，风道导风板的底部安装在蜗壳底板内侧和机座风道底部上。
所述进风蜗壳的断面为由蜗壳顶板、蜗壳侧板和蜗壳底板组成的横U形形状的侧开口结构。
本实用新型的有益效果在于：本实用新型克服现有技术单纯增加风机功率的技术偏见，通过在进风蜗壳的蜗舌区域设置风道导风板，该具有导风装置的悬辊磨，能够使风机提供的绝大部分气流进入磨粉室，减少气流的损耗，提高磨粉机的产量，减小含有粉体的回流气体对进风蜗壳的磨损，降低回流气体对进风气流的干扰，从而增大进风量，该结构简单，具有加工和安装工艺性能好，制作成本低等优点。
附图说明
图1为本实用新型的结构示意图。
图2为图1E-E向的剖视图。
图3为本实用新型的整体结构示意图。
具体实施方式
下面结合附图和具体实施方式对本实用新型作进一步说明。
本专利技术人员在长期的工作实践中发现，在悬辊磨粉机工作过程中，产量并不是随着进风量呈线性增长，其主要原因在于：主机进风蜗壳中蜗舌处为全开放式结构，风机提供的气流一部分通过机座的风道进入磨粉室，还有一部分气流通过开放式的蜗舌又重新回到蜗壳进风口内侧区域，没有进入磨粉室，没有起到输送粉体的作用。也就是说，采用开放式的蜗舌容易导致进风效率低，气流损耗多。
在发现了这一现象后，本专利克服现有技术单纯增加风机功率的技术偏见，以降低回流气体对进风气流的干扰来增大进风量，具体如下：
如图1-3所示，本实用新型提供一种具有导风装置的悬辊磨，包括机座5和进风蜗壳，机座5内沿圆周方向均匀设置有若干个斜向的机座风道立柱6，进风蜗壳由蜗壳顶板1、蜗壳侧板2和蜗壳底板4组成，进风蜗壳的蜗舌区域设置有风道导风板3，风道导风板的3前部为圆弧段，后部为平面段，圆弧段和平面段光滑连接。
圆弧段的风道导风板安装在蜗舌区域的蜗壳侧板2内侧，平面段的风道导风板安装在进风口区域的机座风道立柱6的内侧壁上，风道导风板3的底部安装在蜗壳底板4内侧和机座风道底部上。
进风蜗壳的断面为由蜗壳顶板、蜗壳侧板和蜗壳底板组成的横U形形状的侧开口结构。本实用新型中进风蜗壳的断面形状与申请号为“201610009507.2”的发明专利公开的进风蜗壳的断面形状相同。
本实用新型提供的具有导风装置的悬辊磨，通过在进风蜗壳的蜗舌区域设置风道导风板，能够使风机提供的绝大部分的气流进入磨粉室，减少气流的损耗，提高磨粉机的产量，减小含有粉体的回流气体对进风蜗壳的磨损，降低回流气体对进风气流的干扰，从而增大进风量，该结构简单，具有加工和安装工艺性能好，制作成本低等优点。
以上所述为本实用新型的优选实施方式，应当指出，对于本领域的技术人员来说，本实用新型不受上述实施方式的限制，在不脱离本实用新型整体构思的前提下，还可以做出若干变化和改进，这些也应该视为本实用新型的保护范围。
