| titleOfInvention | Semi-closed air-water backwashing contact flocculation filter capable of automatically exhausting |
| abstract | The utility model discloses a semi-closed air-water backwashing contact flocculation filter capable of automatically exhausting. The top surface of the cover plate of the filter is connected with an exhaust pipe, and an automatic exhaust valve is arranged on the exhaust pipe; a plurality of water caps are fixedly arranged on the water cap arrangement plate; the metal column is connected with a plurality of wire winding pipes and communicated with the wire winding pipes, the metal column is communicated with a central pipe, the central pipe is used as a water inlet after penetrating through the bottom surface of the shell, and the water inlet is connected with a water pipe and then is respectively connected with a water inlet pipe and a back flush drain pipe through an electric three-way valve; a filter material layer is filled between the water cap arrangement plate and the metal column body; the casing lateral wall is equipped with the air inlet, and the trachea is connected to the air inlet outer end, is equipped with electronic admission valve on the trachea. The filter adopts the wire winding pipe for water distribution, thereby not only preventing the loss of filter materials during backwashing, but also pre-filtering and intercepting larger particle impurities in raw water; by adopting the semi-closed filtering technology, the automatic exhaust valve is automatically closed when water is produced, the filter is fully closed, the water production time can be obviously prolonged, and water conservation is facilitated. |
