Description
技术领域
本实用新型涉及一种排污装置，特别是涉及一种循环水流动床生物滤池底部排污装置。
背景技术
循环水养殖由于其节水、环保、高产和可持续等优点，成为当代水产养殖的重要发展方向之一，循环水养殖池一般包括沉淀池和生物滤池，沉淀池通过物理沉淀沉积大颗粒有机物，生物滤池是通过生物膜的硝化作用来处理水中的氨氮等，生物膜老化后脱落于生物滤池的底部，为避免池底污物堆积，需要进行人工清理，费时费力，并且无法实时清理，会对水质在一定程度上产生影响。

本实用新型有益效果是，
(1)通过在滤池底面设置排污孔和滤网，将滤池内杂质穿过滤网由排污孔排出，滤网的孔径可以穿过杂质，但滤网孔径小于滤料直径，可以防止滤料的流失；
(2)排污孔采用上端大下端小的结构，可以在水流压力作用下将堆积在滤网上的滤料冲走，以便更好的滤掉滤池内的杂质；
(3)端部竖管与排污横管之间采用弯头B连接，排污主管与最外侧的端部横管之间采用弯头A连接，可以避免杂质在管端的沉积，使排污更彻底；
(4)该装置结构简单，操作方便，通过控制排污主管的开关即可实现滤池的清理，降低了人工劳动强度，并且清理彻底，有效提升了滤池内的水质。

具体实施方式
下面结合实施例对本实用新型做进一步描述。
如图1-4所示，一4种循环水流动床生物滤池底部排污装置，设有滤池1，滤池1内均布设有排污孔，排污孔上方设有滤网2，滤网2固定在滤池底面4上，如图1所示，滤网2可以做成整体式滤网直接铺设在滤池底面4上，也可以做成如图2所示的分体式滤网，分别固定在每个排污孔上方，可以采用水泥将其嵌入滤池底面4。滤网2的孔径小于滤池1内滤料的直径。
排污孔下方设有排污竖管5，排污竖管5下方连接排污横管8，排污横管8上连接排污主管6，杂质通过排污主管6排出进行集中处理。排污主管6上可以设置阀门用于滤池排污的开关，阀门可以选用手动阀或者电动阀。排污主管6的出口略向下倾斜，有利于排污主管6中杂质的排出。排污主管6的管径大于排污横管8的管径，排污横管8的管径不小于排污竖管5的管径。远离排污主管6一侧的排污竖管5称之为端部竖管10，端部竖管10与排污横管8之间采用弯头B 9连接，排污主管6与最外侧的端部横管11之间采用弯头A 7连接。端部采用弯头连接可以避免杂质在管端的沉积。
如图5所示，排污孔包括上端排污孔3和下端排污孔12，上端排污孔3孔径大于下端排污孔12，排污孔也可以做成如图6所示，在上端排污孔3和下端排污孔12之间设置中间锥孔13，中间锥孔13为上端大下端小的锥孔，用于上端排污孔3和下端排污孔12的过渡。排污竖管5均连接到下端排污孔12上。
本申请通过在滤池底面4上设置排污孔，在排污孔上方设置滤网2，可以使滤池1内的细小杂质穿过滤网2进入到排污孔，进而排出滤池1，排污孔采用上端排污孔3和下端排污孔12相结合，且上端排污孔3直径大于下端排污孔12直径的方式，可以通过排污孔内水流压力将沉积在滤网2上的滤料冲走，方便杂质穿过，提高了排污效率。
该装置结构简单，可以实现流动床生物滤池的快捷清理，并且保证滤料不会通过排污孔流失，降低了人工劳动强度，并且可随时清理，有效提升了滤池1内的水质，改善了养殖环境。
惟以上所述者，仅为本实用新型的具体实施例而已，当不能以此限定本实用新型实施的范围，故其等同组件的置换，或依本实用新型专利保护范围所作的等同变化与修改，皆应仍属本实用新型权利要求书涵盖之范畴。
