A water inlet pipe 6 is provided on the semi-cylindrical cover 2, and the water inlet pipe 6 is connected to the second semicircular mounting groove 5. Two first semicircular holes 20 are mirrored on the trapezoidal supporting shell 1, and two second semicircular holes 21 are mirrored on the semi-cylindrical cover 2. A water wheel assembly for water purification is detachably connected in the trapezoidal supporting shell 1.

[0020] Specifically, the waterwheel assembly includes a fixed shaft 8, a rotating disk 9, a waterproof bearing 10, a plurality of blades 11, two clamps 12, two buckles 15 (the buckles 15 are existing products similar to barbell buckles), a positive dielectric layer 16 and a negative dielectric layer 17, the fixed shaft 8 is inserted into the two first semicircular holes 20, the middle part of the fixed shaft 8 is rotatably connected with the rotating disk 9, the intersection of the rotating disk 9 and the fixed shaft 8 is provided with a waterproof bearing 10, the rotating disk 9 is equidistantly connected with a plurality of blades 11, the fixed shaft 8 is mirror-imaged with a positive dielectric layer 16 and a negative dielectric layer 17, and the positive dielectric layer 16 and the negative dielectric layer 17 are respectively connected by corresponding clamps 1 2 is tightly attached to the fixed shaft 8, the positive dielectric layer 16 and the negative dielectric layer 17 are respectively located at the two ends of the turntable 9, the positive dielectric layer 16 and the negative dielectric layer 17 are in contact with the turntable 9, and the positive dielectric layer 16 and the negative dielectric layer 17 are also in contact with each blade 11, and the two ends of the fixed shaft 8 are detachably connected with two buckles 15, the two buckles 15 are tightly attached to the outer walls of the trapezoidal support shell 1 and the semi-cylindrical cover 2, and the two buckles 15 play a limiting role, which can prevent the fixed shaft 8 from moving, and at the same time, the two buckles 15 apply pressure to the outer walls of the trapezoidal support shell 1 and the semi-cylindrical cover 2, so that the trapezoidal support shell 1 and the semi-cylindrical cover 2 can be fastened.

[0021] Specifically, each first semicircular hole 20 and each second semicircular hole 21 are tightly attached to the corresponding fixed shaft 8; the blade 11 is in contact with the inner walls of the first semicircular mounting groove 3 and the second semicircular mounting groove 5; the first semicircular mounting groove 3 and the second semicircular mounting groove 5 form a cylindrical hollow area, and the central axis of the cylindrical hollow area overlaps with the central axis of the fixed shaft 8.

[0022] Specifically, the positive dielectric layer 16 and the negative dielectric layer 17 divide the cylindrical hollow area into three pancake-shaped sealed spaces, and the pancake-shaped sealed space located between the opposite surfaces of the positive dielectric layer 16 and the negative dielectric layer 17 is the water purification area; the water outlet pipe 4 and the water inlet pipe 6 are connected to the water purification area; the water purification area is divided into a plurality of sealed trapezoidal water purification tanks by a plurality of blades 11; the positive dielectric layer 16 is made of nylon material, the negative dielectric layer 17 is made of polytetrafluoroethylene material, the turntable 9 and each blade 11 are made of polyvinyl chloride material, and nylon is ranked behind polyvinyl chloride in the triboelectric sequence, so when polyvinyl chloride is rubbed against nylon, due to the high triboelectric electronegativity of polyvinyl chloride, nylon will lose electrons and become positively charged; the polytetrafluoroethylene material is ranked ahead of polyvinyl chloride in the triboelectric sequence, and when polyvinyl chloride is rubbed against polytetrafluoroethylene, the polytetrafluoroethylene material will gain electrons and become negatively charged, thereby forming an electric field in the water purification tank.

[0023] Working principle: The water to be purified enters the water purification tank from the water inlet pipe 6, and is affected by gravity, driving the turntable 9 and each blade 11 to rotate. The positive dielectric layer 16 and the negative dielectric layer 17 are respectively charged with positive and negative charges under the friction of each blade 11. Since the blade 11 rubs against the two layers at the same time, the positive and negative charges cancel each other out, so the rotating plate 5 is not charged, so an electric field is formed in each water purification tank. Under the action of the external electric field, the anions and cations of the water in the water purification tank are respectively adsorbed on the positive dielectric layer 16 and the negative dielectric layer 17, and temporarily stored to remove ammonia nitrogen, salts, organic matter and heavy metals in the water. When the water purification tank rotates to the water outlet pipe 4, the purified water is discharged from the water outlet pipe; When the device needs to be maintained, it is only necessary to remove the two buckles 15, open the semi-cylindrical cover 2, take out the entire waterwheel assembly, then remove the two clamps 12, take out the positive dielectric layer 16 and the negative dielectric layer 17, clean off the impurities attached thereon, and then reverse the above steps. After the device is reassembled, it can be used again.
