Anti-backflow well lid for paper mill wastewater treatment
The invention relates to the field of paper mill wastewater treatment equipment, in particular to an anti-backflow well lid for paper mill wastewater treatment. The anti-backflow well lid for the paper mill wastewater treatment comprises a well lid body of which the upper end and the lower end are communicating, a well end cover is mounted at the upper end of the well lid body, a hydraulic oil change port is fixedly mounted outside one side of the well lid body, the anti-backflow well lid further comprises an inlet anti-backflow structure composed of two anti-backflow doors and a filter screen arranged above the anti-backflow doors, and further comprises an inner wall cleaning fan structure composed of a fan and a waste water collecting cavity. Through the arrangement, discharged waste liquid, sewage and the like of a paper mill can be filtered, solid impurities are removed, blockage is prevented, meanwhile, waste liquid backflow is prevented, after discharging is completed, the discharged waste liquid can be used for cleaning the interior of the well lid to reduce corrosion and adhesion.
本发明涉及造纸厂污水处理设备领域，具体是一种造纸厂废水处理用防倒流井盖，包括上下两端贯通的井盖体，井盖体上端安装有井端盖，所述井盖体一侧外固定安装有液压换油口，还包括两个防倒流门以及设置在防倒流门上方的过滤网共同组成的入口防倒流结构，还包括由风扇和废水收集腔组成的内壁清洁风扇结构，这样的设置可以使得造纸厂废液污水等排放进行过滤去除固体杂质防止堵塞同时防止废液倒流且完成排放后可以利用排放的废液对井盖内部进行清理减少腐蚀与黏连。
