during operation, firstly, the valve 9 of the primary filter tank 11 is opened, then the power supply of the water suction pump 8 is opened to pump the underground water into the primary filter tank 11, the underground water is filtered through the first filter plate 112, sand and stone in the underground water and impurities with large volume are retained on the upper end surface of the first filter plate 112, and due to the gravity action of water flow and the impurities, the sand and stone in the underground water and the impurities with large volume are adsorbed on the upper end surface of the first filter plate 112 to form a layer of filter cake, and the filter cake, the small impurities and the sewage flow into the secondary filter tank 12 through the filter holes of the first filter plate 112.
The valve 9 at the second water through opening 121 of the secondary filtering tank 12 is closed, when the inner cavity of the secondary filtering tank is filled with groundwater, the valve 9 of the primary filtering tank 11 is closed, and at this time, the agent for removing the specified metal impurities can be added into the solvent bottle 2. For example, when lead ions in groundwater exceed the standard, a ferrite solution is added into a clean empty solvent bottle 2, then a valve 9 for communicating the solvent bottle 2 and a secondary filter tank 12 is opened, a quantitative ferrite solution is added into the secondary filter tank 12, then a power supply of a motor 31 is turned on, the groundwater of the secondary filter tank 12 is stirred by a stirring blade 33 to promote the reaction of the ferrite solution and the lead ions in the groundwater, the lead ions are oxidized into white precipitates for precipitation by utilizing the strong oxidizing property of the ferrite, and then the power supply of the motor 31 is turned off.
Then, the valve 9 communicating with the third-stage filtration tank 13 is opened, white precipitated substances containing lead ions and small impurities in the groundwater are retained on the upper end surface of the second filter plate 122 through the second filter plate 122, a filter cake is formed after long-term accumulation, and the rest of the groundwater flows into the third-stage filtration tank 13 through the second water vent 121. Then, the valve 9 of the third stage filter tank 13 is opened, and the groundwater flows out from the valve 9 of the third stage filter type to the water tank 6 after being filtered and purified by the third filter plate 132. Thereby, the filtering and purifying process of the groundwater is completed.
As shown in fig. 6, when the first filter plate 112 and the second filter plate 122 in the multistage filter tank 1 need to be cleaned, the underground water in the multistage filter tank 1 is drained, the jackscrew 43 on the side surface of the multistage filter tank 1 close to the opening 18 is unscrewed, the handle 42 is pulled to pull the sealing plate 4 out of the through groove 19, the first filter plate 112 is slid to the opening 18 along the length direction of the dovetail groove 14 until the cylindrical block 17 abuts against one end of the limiting groove 16, after impurities such as sand and stones on the upper end surface of the first filter plate 112 are cleaned, the first filter plate 112 is turned over downwards, and then the impurities on the upper end surface of the first filter plate 112 are cleaned onto the hopper 5. Then, the second filter plate 122 is slid along the longitudinal direction of the dovetail groove 14 toward the opening 18 until the cylindrical block 17 abuts against one end of the stopper groove 16, the second filter plate 122 is turned over downward with the cylindrical block 17 as a rotation point until the second filter plate 122 is placed on the hopper 5, then impurities such as white precipitates on the upper end surface of the second filter plate 122 are cleaned, and then the impurities such as white precipitates on the upper end surface of the second filter plate 122 are cleaned up on the hopper 5.
Then, all the impurities such as sand and white precipitate above the hopper 5 are cleaned into the garbage can 7 below the hopper 5 along the inclined direction of the hopper 5. Finally, the first filter plate 112 and the second filter plate 122 are respectively installed in the primary filter tank 11 and the secondary filter tank 12 along the dovetail grooves 14, and then the sealing plate 4 is slid until the sealing plate 4 is aligned with the side of the multistage filter tank 1, and then is fixedly installed by the jackscrews 43. Thereby completing the cleaning process of the first filter plate 112 and the second filter plate 122.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
