Abstract
轴向通风器,带有一个进气流部件,以及一个圆柱形外壳。在外壳内装有一个转子,通风器提供稳定气流分离限制范围的装置。它由一个固定导流环组成,导流环的直径大致与圆柱形外壳的直径相等。在导流环的外围有环形气流通道,导流环离环形气流通道的二端距离相等。导流叶片设置在环形气流通道内,并对它的轴成倾斜,导流叶片的进、出气口的边缘倾斜外伸,并由多个平片组成。
Description
本发明涉及一种轴向通风器,它具有由权利要求1所述部件的各种特征。
在由YGB-动力技术75(1977),第159-165页所介绍的轴向通风器中,气流的分离作用能够在传送较小的风量时受到减弱,在旁路环形气流通道中,产生在转子的外侧直径处的回流能局部地受到稳定。因此,在回流中出现的旋流可以利用环形气流通道内的导向叶片来进行导向。
从国际专利申请(WO 85/00640)所述的轴向通风器可知,其中所述的导流叶片在环形气流通道内是做成弯曲的,这种导流片的制造增加了轴向通风器的成本。
本发明的目的是根据实际使用的方式来简化上述类型的轴向通风器,同时提高气流分离的限制范围。
该目的可以在上面所提到型式的轴向通风器中利用权利要求1的特征部件来予以解决。发明的一个简便的实施例由从属权利要求予以陈述。
平面的叶片相对于弯曲的叶片来说可以采用更为简单和化费少的方法来进行制造,气流的分离特性也受到导流叶片的出气边缘的倾斜作用的有利影响。平面导流叶片可以沿轴向设置,并且相对于轴向通风器的直径方向成倾斜,或沿径向设置,并且相对于导流环的园周方向成倾斜。
在国际专利申请WO 82/01919中,描述一种轴向通风器,它含有平面导流叶片。然而,这些导流叶片完全沿径向和沿轴向设置,并且把导流环连接到侧壁,以离开转子的端面处的侧壁来限定环形气流通道,所以空气不能径向地在该位置处逸出,结果这种装置的效率通常受到负的影响。
本发明的几种实施例由附图示意说明,并且在下面的文字部分内对此作出更为详细的述说。其中
附图1,表示按本发明所述的轴向通风器的局部剖视的纵向正视图。
附图2,表示根据图1的Z部分放大的细节图。
附图3,表示图2中的Ⅲ-Ⅲ剖视图。
附图4,表示图2中的Ⅳ-Ⅳ剖视图。
附图5,表示根据图2,对另一种实施例的Ⅲ-Ⅲ剖视图。
附图6,表示根据图2,对该实施例的Ⅳ-Ⅳ剖视图。
附图7,表示本发明其它实施例的局部纵向剖视的正视图。
轴向通风器有一个外壳(1),它包括一个锥形收缩的进气流部件(2),和紧挨着该部件安装的一个园柱形外壳部件(3),一个转子(4)可以在园柱形外壳(3)中旋转,转子叶片(5)是可调的。
一个用于稳定气流分离限制范围的装置,它由一个导流环(6)和围着导流环(6)的环形气流通道(7)组成。导流环与转子(4)相连,利用外壳(1)的外罩将环形气流通道(7)在径向方向限定在外侧上,在该气流通道区,外壳的直径增大,用二个侧壁(8),(9)作为气流通道的侧壁,根据图1和图2可见,侧壁(8)和(9)垂直于园柱形外壳部件(3)向外伸出,侧壁(8)和(9)也能以锥状形式设置,如图7所示那样。也可以将侧壁(8),(9)之一做成锥形的样子,而将另一侧壁为垂直方式。
由图1和图7可见,在园柱形外壳部件(3)内,设置有导流环(6),导流环的直径大致上与园柱形壳体(3)的直径相等,而它的轴向长度小于环形气流通道(7)的轴向长度,导流环(6)以相对于环形气流通道(7)的方式设置,即使导流环(6)离开侧壁(8)(9)有相等的距离,导流环(6)分别在环形气流通道(7)的进气口侧和出气口侧上留有敞开的气流通孔。
导流叶片(10)位于环形气流通道(7)内,由叶片控制产生的回流。导流叶片(10)被连接到导流环(6)和外壳(1)上,导流叶片(10)的出气和进气边缘成倾斜地向外伸出。而在径向,导流叶片(10)的长度增加。
导流叶片(10)由多个平片组成,这些平片相对于环形气流通道(7)的纵轴倾斜,由图3和图4可见,导流叶片(10)与轴向平行设置,并且相对于导流环(6)的直径方向成倾斜。在图5和图6所示的实施例中,导流叶片(10)被径向设置,并且朝着导流环(6)的园周方向成倾斜。在这些图中,箭头方向表示转子(4)的旋转方向,各自的倾角应该在20度至70度之间。在图示的轴向通风器内,所示的倾角角度为45度。
