一种板袋式曝气器
本技术属于水处理
,具体涉及一种水处理过程中使用的曝气器。
技术介绍
曝气器是水处理领域最为广泛使用的装置,其主要种类有微孔曝气器及射流曝气器。近年来,一种膜瓣式曝气器的出现使得曝气器的结构更为简单、紧凑,曝气效果及曝气效率相对于传统曝气器均有一定幅度的提升。该种曝气器通过将薄膜覆盖在曝气支架上,薄膜四周密封压实,然后在曝气支架的底部设置进气通道,由薄膜上的曝气孔射出。在使用过程中发现,该膜瓣式曝气器存在下列问题:1、曝气支架面积有限,导致曝气面积受限;2、瓣膜与曝气支架的密封性难以确保;3、采用瓣膜覆盖曝气支架的方式,曝气支架结构复杂,导致生产成本增加。
技术实现思路
为解决现有技术中存在的技术问题,本技术提供一种板袋式曝气器。为实现上述技术目的,本技术采用的技术方案为:一种板袋式曝气器,包括曝气袋,其特征在于:所述的曝气袋的上表面均布曝气孔,曝气袋的下表面向外侧延伸形成翼边;还包括一支撑板,曝气袋的下表面与支撑板紧贴,翼边向下翻折对支撑板的边缘形成反包,在支撑板的四周设有夹紧框,所述的夹紧框带有U型槽口,支撑板的四周及翼边由U型槽口夹紧,夹紧螺栓贯穿夹紧框的顶部框边、支撑板及翼边,夹紧螺栓的顶端与底端分别设有锁紧螺母;在支撑板的背面设有进气口,进气口与曝气袋的内腔贯通,进气口上连接进气管。进一步的,所述曝气袋的上表面与下表面之间设有若干平行的粘结条,粘结条将上表面及下表面粘接为一体,从而将曝气袋的内腔分割呈若干空腔,若干空腔的端部贯通。进一步的,所述曝气袋的下表面设有充气口,进气管穿过支撑板上的进气口与充气口密封连接。进一步的,所述 ...
