Description

Technical Field

[0001] The utility model relates to the technical field of filter material cleaning, in particular to an air-water combined backwashing device. Background Art

[0002] During the filtration process of the water treatment plant, the filter material will gradually be contaminated by impurities in the water, which will reduce the filtration efficiency. In order to keep the filter material clean and have a good filtration effect, backwashing operations are often required;

[0003] Backwashing refers to flushing out impurities, sediments and particles trapped in the filter medium through reverse water flow to restore the filtering capacity and efficiency of the filter media. During the backwashing process, in order to further improve the cleaning effect, gas (usually air) and water are combined to reversely clean the filter media;

[0004] However, in the process of backwashing the filter media with a combination of air and water, it was found that the impurities accumulated in the filter media were located at different locations. When the air and water were mixed and passed through the filter media at a uniform speed, the mixed air and water would preferentially pass through the locations with less impurities. This resulted in a longer time for cleaning different locations of the filter media when the air and water were mixed, making it difficult to ensure that the filter media could be cleaned of impurities evenly and sufficiently.

[0005] In summary, there is a need for a combined air-water backwashing device that can clean evenly. Utility Model Content

[0027] In this embodiment, a liquid pump 13 is provided in the water pumping chamber, and a water outlet pipe 14 and a water inlet pipe 15 are provided at both ends of the liquid pump 13. The water outlet pipe 14 is communicated with the water collecting chamber, and the water inlet pipe 15 extends to the outside of the water washing box 11. The liquid pump 13 is provided to send water into the water collecting chamber and the water washing component 4 to backwash the filter material 6.

[0028] In this embodiment, the water washing assembly 4 includes a water guide pipe 41, a backwash pipe 42 and a water outlet 43. The water guide pipe 41 is arranged on the side of the water washing box 11, and the water guide pipe 41 is connected to the water collecting chamber. A plurality of backwash pipes 42 are arranged at one end of the water guide pipe 41 away from the water washing box 11.
