2, the utility model filter process and cleaning process are carried out simultaneously, not influenced by it, when raw water quality changes, can adjust the washed-out sand amount of washed-out sand system, guarantee the cleaning performance of filtrate.
3, the utility model treating capacity is big, and in addition, it is more thorough that three cover sand-washing devices can clean filtrate.
4, sand extraction tube of the present utility model upwards inserts the sand-washing device from the filtering container bottom, and like this, when the quartz sand that provides in carrying the sand device was transported to sand-washing device, the kinetic energy of quartz sand ran out, slowly falls under the effect of gravity then, and cleaning performance is relatively good.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of radiant type water feed apparatus in the utility model.
1 filtering container, 2 sand extraction tubes, 3 sand-washing devices, 4 water inlet pipes, 5 water legs, 6 mill weirs, 7 delivery ports, 8 blow-off pipes, 9 radiant type water feed apparatus, 10 airducts, 11 sewage chamber, 12 sand separators, 13 air-floating apparatus 14 unload sandpipe 15 drainpipes 16 water distributors
Five, the specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, this continuously automatic sand filter comprises filtering container 1, filtering container 1 diameter is four meters, and certain thickness quartz sand filter media is housed in the container, forms sand filter blanket, it above the sand filter blanket clean water chamber, clean water chamber is provided with water leg 5, and water leg 5 is arranged on the inwall of filtering container 1, in the form of a ring, water leg 5 is provided with height-adjustable sewage mill weir 6, and water leg 5 connects delivery port 7; For attractive in appearance reaching do not stop that quartz sand filter media falls, water inlet pipe is installed in the top of filtering container 1 in the present embodiment, is positioned at blow-off pipe 8 belows, is inserted into the bottom of sand filter blanket then along down at right angles, water inlet pipe 4 connects radiant type water feed apparatus 9, and the sand separator 12 of umbrella shape is installed in the water inlet pipe below; Sand extraction tube 2 upwards inserts the sand-washing device 3 from filtering container 1 bottom, airduct 10 enters the filtering container 1 from the top of filtering container, and be inserted to the bottom of sand extraction tube 2 downwards and be connected with sand extraction tube 2, blowing device is supplied with the washed-out sand system by airduct 10 with wind, the one, ensure that the dirty sand in the filtering container 1 continuously cleans by sand extraction tube 2 supply sand-washing devices 3, the 2nd, by compressed air the filtrate after washing in the sand-washing device 3 is cleaned once more completely, the dirt of filter material surface is taken away; The bottom of filtering container 1 is taper, and the bottom of conical bottom and side thereof are respectively equipped with drainpipe 15 and unload sandpipe 14; Sand-washing device 3 connects sewage chamber 11, sewage chamber 11 connects leads to the outer blow-off pipe 8 of filtering container, sewage chamber 11 tops are lower than water leg 5 horizontal planes, the top of sand-washing device 3 is a umbrella shape, air-floating apparatus 13 is equipped with in sand-washing device 3 bottoms, the sewage mill weir 6 of water leg 5 in the middle of sand-washing device 3 is looped around is kept apart washed-out sand sewage and clear water.
