| 20110155655 | MODULAR INTEGRATED WATER-PURIFYING DEVICE - In a kind of modular integrated water purifying device, including reaction tank, sedimentation tank and filter pool, a pump is connected to the top side of the reaction tank through pipes and valves. There are variable grid hole mixing paddles in the reaction tank, forced outlet pipe at the bottom of sedimentation tank and the same-flow ramp board in the middle. The sedimentation water collector is set up below the board, with the purified water outlet tube connected. The traveling sludge sucker sits on the top of filter tank and move back and forth. Blanket-shape filters is vertically fixed in the filteration tank, the mud-suction pump below to the raveling mud-suction machine connects to the mud-suction pipe another side to the blanket-like wedge filters. At the bottom of the filteration tanker lie the water-collecting main pipe and clean water outlet, the effluent weir is fixed inside of the filteration tank. | 06-30-2011 |
