Abstract

声波清灰器涉及一种装在除尘设备上的膜片式声波清灰装置。主要是为解决现有的膜片式声波清灰器进入壳体的压缩空气压力无法控制,膜片易疲劳损坏,使用寿命短,声强不稳定,清灰效果不好等问题而设计的。它有壳体、上盖、壳座、发声体、膜片、起振室、发声室、进气孔、出气孔、出气孔盖、扩声喇叭,特征是在发声体下方设共振室,在发声体上设共振孔将发声室与共振室联通;在发声体上设压力平衡孔,将发声室与起振室联通,在起振室内设调压环,在膜片上方设耐磨垫。优点是膜片不易疲劳损坏,使用寿命长,声强稳定,清灰效果好。

Description

声波清灰器
[技术领域]
本实用新型涉及一种装在除尘设备上的膜片式声波清灰装置。
[背景技术]
现有的膜片式声波清灰器包括壳体、上盖、壳座、膜片、进气孔、出气孔、出气孔盖、扩声喇叭、发声体、起振室、发声室等,缺点是进入壳体的压缩空气的压力无法控制,膜片易疲劳损坏,使用寿命短,声强不稳定,清灰效果不好。
[发明内容]
本实用新型的目的是提供一种膜片不易疲劳损坏,使用寿命长,声强稳定,清灰效果好的声波清灰器。
上述目的是这样实现的:与现有技术相同的是它有壳体,壳体上面有上盖,壳体下面有壳座,壳体内有发声体,发声体上方是装在壳体内的膜片,发声体外环面与壳体之间是起振室,发声体内环面与膜片之间是发声室,起振室侧面的壳体上有进气孔,上盖上有出气孔,出气孔上有出气孔盖,在壳座下方装有扩声喇叭,与现有技术不同的是在发声体下方设共振室,在发声体上设共振孔将发声室与共振室联通,使声强增强;在发声体上设压力平衡孔,将发声室与起振室联通,平衡它们的压力,起保护膜片作用;在起振室内设调压环,调整压力平衡,增强稳定性。
为了进一步保护膜片,可在膜片上方设耐磨垫3。
本发明的优点是膜片不易疲劳损坏,使用寿命长,声强稳定,清灰效果好。
[附图说明]附图是本实用新型的剖面示意图。
[具体实施方式]
参照附图,与现有技术相同的是它有壳体4,壳体上面有上盖1,壳体下面有壳座14,壳体内有发声体5,发声体上方是装在壳体内的膜片2,发声体外环面与壳体之间是起振室15,发声体内环面与膜片之间是发声室16,起振室侧面的壳体上有进气孔11,上盖上有出气孔12,出气孔上有出气孔盖13,在壳座下方装有扩声喇叭8;在发声体下方设共振室9,在发声体上设共振孔7,将发声室与共振室联通;在发声体上设压力平衡孔10,将发声室与起振室联通;在起振室内设调压环6;可在膜片上方设耐磨垫3。
