Abstract
本发明涉及一种超声波喷涂装置,包括壳体1,壳体内装有能产生压电振动的芯子2,振动被传送到装有待雾化液体的喷嘴5,在此装置中,振动片9安放在紧靠着所述的喷嘴5的自由端,振动片9是用来改善液体的雾化特性的。
Description
本发明是关于超声波喷涂装置,包括一个壳体,壳体内装有产生压电振动的芯子,上述振动被传送到装有待雾化液体的喷嘴上。
本发明的目的是提供一种能显著地改善被喷液体的雾化特性的装置。
本发明的目的就是为了产生一束密集的极细的雾状液滴,可把它喷到较远的距离,而且是用特定的振动频率,液滴的体积比普通的要小。
“密集”是指水滴被喷涂装置分散开并由空气传送,这种水滴呈束状,当水滴离开喷嘴时不会因重力而很快下降,而是以一个锥形喷到尽可能远的地方。
装有这种喷嘴的装置在比利时专利902,301中已经讨论过。在此专利所公开的装置中,会遇到这样的问题,即:由于被喷液体离开喷嘴后不久就向下运动,这样被喷液体所覆盖的表面积就相当有限。
因此本发明的目的是为了克服上述缺点并提供一种喷涂装置,它可以使被喷涂的液体以更高的均匀性喷到距离比较远的大面积表面上。
为了取得如本发明所述的结果,所述的喷嘴靠着自由端安装一块振动片,用它来改善液体的雾化特性。
对本发明的其他细节和特征,将通过非限定性的例子,并参考附图在下面加以说明,在附图中:
图1是根据本发明所制作的喷涂装置的部分纵剖图。
图2是表示超声波喷涂装置没有装上振动片时喷出的液体束。
图3表示同一个液体束在喷涂装置装有如本发明所述的振动片时的状态。
如图1所示的装置包括里面装有芯子2的外壳1,芯子包括所要求的用来产生所需的超声振动的压电元件。数字3表示跟接头4相连的导线。芯子2同称之为喷嘴5接在一起,喷嘴5的自由端6的横截面扩大了,它用于这个实施例中,但并不是必需的。壳体1跟延长件7相连接,而延长件7完全围住上述喷嘴5。
从供液口8把要雾化的液体供应到设在喷嘴5内的中央通道,虽然液体可能沿喷嘴5向外流出来。
为了用本发明的方法改善被喷液的雾化特性,把振动片9同喷嘴5上扩大部分6相接触。
采用与喷嘴5的扩大部分6相接触的振动片9,组成了本发明的实质内容。
尽管例中所示的喷嘴有一个扩大部分6,但本发明也自然可用其他完全不同形状的喷嘴。
已经弄清楚,在装有上述用来产生超声振动的元件的装置中,液体的雾化在特别适宜的条件下进行。在液体通过同上述类型喷嘴相接合的振动片时发生雾化,产生一束极细的液滴,这束极细的液滴在离开上述喷涂装置适当的距离内仍然保持密集状态。如图3所示,这种密集状态外形近似于一个锥体。
若不用本发明所述的振动片时,由喷涂装置喷出的雾束基本上如图2所示的形状。
在图2中可以注意到,当被喷液滴离开喷嘴以后就直接往下降落这就意味着喷出的液滴所覆盖的区域很有限,而且离喷嘴的距离太近。
采用本发明的喷涂装置克服了这些缺点,而且产生了锥形的雾束10,它可以达到较远的距离,覆盖较大的表面积,而且喷涂得更加均匀。
可以采用多种材料来制作振动片9。振动片可以用织物制成,但也可以由多孔材料或可透水的非编织材料制成。
采用由Dupont de Nemours公司制造的商标为“KEVLAR”的纤维取得了显著的效果。
对同喷嘴5相接合的振动片9有一个要求。假定冲击到振动片上的振动使流过振动片的液滴颗粒加速。已经确定,使用这种振动片改变了空气动态特性,出现了强烈的空气流动,结果使液体颗粒移动到所要求的距离。
这就解释了为什么液体束或水滴同被加速的周围空气一道呈现如图3所示的形状。
当喷出的液体(特别是这些组成喷雾的水滴)没有得到足够的加速时,就产生了如图2中11所示的形状,从而带有同此有关的一切缺陷。
根据本发明所制的喷涂装置可用在各种领域。在用雾化或喷涂的所有领域内,本发明所述的装置均具有显著的优点,这是由于可以把液滴喷涂到较远的距离,而且所产生的喷雾非常均匀,都是由极细的液滴组成的。所有这些特性都不必依靠增加振动频率。
应该明白,本发明并不限于上述的实施例,实施例可以作很多变化,但不会超出由附加的权项所限定的本发明的范围。
