带反冲洗的污水提升设备
本技术涉及一种污水提升设备,尤其是涉及一种带反冲洗的全自动污水提升设备。
技术介绍
带有排污泵的污水提升设备一般安装在位于污水水底的集水箱内底部,用于排出抽进集水箱内的污水。随着污水的不断涌入,污物在集水箱底部也即泵底会越积越多。尤其是在停机一段时间后再次开启污水提升设备进行排污时,部分污物可能已经干涸,单靠泵的吸力可能无法将这些污物排出,需要先进行反冲刷、稀释等操作,这样才不至于影响到泵的正常工作。但,现有的设有反冲洗的污水提升设备有如下的不足之处:1.其反冲洗的水也是来自于集水箱的污水,往往含有较大的杂质,未经过滤很容易堵塞孔径较小的反冲洗管;2.其反冲洗时只是冲洗固液分离器,并没有冲洗集水箱的底部和排污泵的进口;3.反冲洗不可控。而若反冲洗管被堵塞或未冲洗反冲洗管水箱底部及排污泵进口的淤泥,会降低污水提升设备的稳定性和耐用度,增加污水提升设备的制造及维修成本。
技术实现思路
本技术所要解决的技术问题,就是提供一种结构简单且反冲洗可控的带反冲洗的污水提升设备,其反冲洗的水经过滤网过滤掉较大的杂质,不会堵塞反冲洗管,确保水箱底部不会产生淤泥,提高 ...
