Description

     防尘罩及带有该防尘罩的旋风除尘器
本发明涉及一种改进的防尘罩及带有该防尘罩的装置。
在用于过滤气流的旋风式除尘器上通常连接着一个防尘罩。在带有双旋风分离装置、即串联有两个旋风除尘器以便先除去较大的尘粒及绒毛而后再除去较小的尘粒的装置上，该防尘罩设置在这两个旋风除尘器之间。气流通过该防尘罩，从而可减少较大的尘粒及绒毛进入第二个高效旋风除尘器的可能性。
人们已经发现，防尘罩的特性不同会对分离装置的整体性能产生一定的影响。因此，本发明的目的在于提供一种防尘罩，它可以改进与之连接使用的旋风除尘器分离装置的整体性能。
本发明提供一种如权利要求1所述的防尘罩。其优选及最佳的特征包括在其从属权利要求中。在与双旋风分离装置联合使用时，这些方案可改进留在低效旋风除尘器中的尘埃、灰粒及绒毛的百分含量。从而可改进高效旋风除尘器的性能，进而改进整个分离装置的性能。
以下将借助于附图进一步描述本发明的实施例。其中：
图1为本发明防尘罩的侧视图，其中带有局部剖视部分；
图2a为图1所示实施例中的多孔部分壁板的放大视图；
图2b为图1所示实施例中局部放大视图；
图3为本发明第二实施例的侧视图；以及
图3a为图3所示实施例中的多孔部分壁板的放大视图。
图1表示了一个带有一柱形件12的防尘罩10，在柱形件中设置有一个多孔部件14。从多孔部件14的下端缘16延伸出一个凸缘部分18。关于凸缘部分18下面将会详细说明。从多孔部件14的下端缘还有一个沿径向向内延伸的环形腹板20用以连通或密封内旋风除尘器2。内旋风除尘器22本身并不构成本发明的一部分，因而在此不再赘述。腹板20有效地为柱形件12提供支撑及密封。在柱形件12的上方还有一个支撑、密封件24。不过，件24除了为柱形件12提供支撑外本身并不构成本发明的一部分。
图2a以剖视图表示了构成多孔部件14的壁板26的一部分。壁板26具有一个气流迎接表面28和多个通孔30。在工作时，气流沿箭头32所指方向通过通孔。在已有的防尘罩中，通孔是以这样的方式形成的，每个通孔的上边缘在与防尘罩的上游表面相接处有一个圆角半径。而根据本发明，各通孔30的上边缘则以尖角与气流迎接表面28相接。通过钻孔工艺、或根据需要通过模压等任何其他适当的工艺加工通孔30即可形成这样一种尖角。在各通孔30的上边缘与防尘罩10的气流迎接表面28交接处制出尖角可减少通过通孔30的细小尘粒的量，从而减少了通孔30被尘粒及绒毛堵塞的可能性。
壁板26的材料厚度t大致为2mm。各柱形通孔30的直径d大致为2.2mm。
图1所示的实施例还包括一个从多孔部件14的下边缘16延伸出来的凸缘部分18。图2b中更为详细地表示了该凸缘部分18的结构。该部分主要由一对大致平行于防尘罩10的纵向轴36的侧板34构成。该平行侧板34的末端有一个大致为45°的倾斜角α。凸缘部分18的始端上制有一个台阶38。台阶38的宽度b大致等于平行侧板34的宽度B。在本实施例中，宽度b及宽度B均大致为2mm。
台阶38的高度h大致等于台阶38的宽度b，因而在本实施例中也大致等于2mm。
凸缘部分18从多孔部件14下边缘16向下延伸的距离x大致为15mm。
业已发现，在将防尘罩10设置在双旋风真空除尘器中低效旋风除尘器与高效旋风除尘器之间的气流通道时，将防尘罩10的下凸缘部分18制成这种形状，可减少防尘罩10中的多孔部件30中的堵塞量以及细小尘粒通过孔30的量。较多的尘埃及灰粒被保留在低效旋风除尘器中。此外，台阶38还可进一步改善凸缘部分18与多孔部件14的下边缘16之间的密封性。
图3表示了本发明的第二实施例。在图3中所示的锥台形防尘罩40上有一个位于其上边缘的支撑部件42。在该锥台形防尘罩40中设置有一个锥台形多孔部件44。在多孔部件44上布置有多个通孔46。图3a为一剖视图，其中表示了多孔部件44的侧壁48的结构。
如图3a所示，防尘罩40的侧壁48的材料厚度t大致为2mm。各柱形通孔46的直径d大致为2.2mm。各通孔46的纵向轴线大致垂直于防尘罩40的纵向轴线50。各通孔内壁与侧壁48的外表面的交角为锐角。
在所示的该实施例中，侧壁48与防尘罩40的纵向轴线50之间的倾角β大致为12.5°。不过该倾角可根据旋风除尘分离装置的需要、特别是根据高效旋风除尘器的侧壁的倾斜角选择其他值。倾角β最好大致等于高效旋风除尘器侧壁的倾角，以便于使防尘罩40的侧壁48可位于与高效旋风除尘器的倾斜壁平行的位置，从而可为通孔与高效旋风除尘器之间的气流提供通路。
在具有2.2mm直径的通孔上提供尖角有利于减少通过防尘罩的细小尘粒量，从而减少防尘罩被尘粒及绒毛堵塞的可能性。提供圆锥形防尘罩40可增加低效旋风除尘器中收集尘埃及灰粒的面积量，从而提高了旋风除尘器的容量。
对于本领域技术人员，本发明并不限于上述的实施例。对于本领域技术人员很明显，还有许多改进方案及变换方案也落入本发明的保护范围内。
