Anti-clogging system of submersible sewage pump in sewage pump house of subway station
The invention discloses an anti-clogging system of a submersible sewage pump in a sewage pump house of a subway station. The anti-clogging system comprises the submersible sewage pump, a main drainagepipe, a pressure waste water pipe and a back flush pipe; the back flush pipe is connected in parallel with a back flush reinforcement pipe, after the back flush reinforcement pipe extends to the ground of the sewage pump house, the back flush reinforcement pipe is laid on the outer circumference of the submersible sewage pump in a surrounded mode through a first branching pipe, an incline sprayeris arranged on the first branching pipe, and a back flush reinforcement device is formed; a criss-cross pipe network is formed through a second branching pipe, the ground of the sewage pump house isbespread with the pipe network, an upper sprayer is arranged on the second branching pipe, and an up-flow-type sludge back flush device is formed together; and a protective net is further arranged inthe sewage pump house, the protective net is fixedly installed on the ground of the sewage pump house, and covers the submersible sewage pump and the pressure waste water pipe, the cross section of the protective net is smaller than the inner section of the sewage pump house in the station, and the height of the protective net cannot be lower than the high alarm water level of the sewage pump house. Anti-clogging is achieved by a combination of measures, and frequent maintenance affecting the normal operation of the subway station can be avoided.
本发明公开了一种地铁车站污水泵房潜污泵防淤堵系统，包括潜污泵、主排水管、压力废水管和反冲洗管；反冲洗管并联有反冲洗加强管，反冲洗加强管延伸至污水泵房的地面后，通过第一分支管环绕铺设在潜污泵的外周，第一分支管上设置有斜喷头，构成反冲洗加强装置；通过第二分支管形成纵横交错的管网并铺满污水泵房的地面，第二分支管上设置有上喷头，共同构成升流式污泥反冲洗装置；污水泵房内还设置有防护网，防护网固定安装在污水泵房的地面上，并将潜污泵和压力废水管罩在其中，防护网的横截面小于车站污水泵房的内截面，防护网的高度不得低于污水泵房的高报警水位。多管齐下防淤堵，能避免频繁检修影响地铁车站的正常运营。
