DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0028] See also Figure 1-Figure 5 The present application provides a pure water filtration structure, including a first filter component 20 and a second filter component 30.

[0029] The first filter assembly 20 performs primary sedimentation filtration on the raw water, and then the raw water is deep-filtered through the second filter assembly 30 to improve the filtering effect.

[0030] See also Figure 1 , Figure 2 and Figure 3 The first filter assembly 20 includes a first filter tank 210, the top of the first filter tank 210 is connected to a water inlet pipe 250, and the bottom of the first filter tank 210 is connected to a connecting pipe 240; wherein, raw water enters the first filter tank 210 through the water inlet pipe 250 for initial stirring and filtration, and then enters the second filter tank 310 through the connecting pipe 240.

[0031] In this embodiment, a stirring member 220 is installed inside the first filter tank 210. The stirring member 220 includes a driving motor 221, a stirring rod 222 and a spiral stirring blade 223. The driving motor 221 is installed on the top of the first filter tank 210, the top of the stirring rod 222 is fixedly connected to the driving end of the driving motor 221, the bottom of the stirring rod 222 movably passes through the top wall of the first filter tank 210 and extends to the inside of the first filter tank 210, and the spiral stirring blade 223 is installed on the stirring rod 222. A primary filter screen 230 is installed below the spiral stirring blade 223 in the first filter tank 210. Among them, after the raw water enters the first filter tank 210, the medicine is added, and then the drive motor 221 is started to rotate the stirring rod 222, and then the spiral stirring blade 223 rotates to achieve mixing of the raw water and the medicine, which can flocculate the sediment in the raw water, and then precipitate the sediment through the primary filter net 230, and the water flows into the second filter tank 310 through the connecting pipe 240.

[0032] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 The second filter assembly 30 includes a second filter tank 310, the other end of the connecting pipe 240 is connected to the top of the second filter tank 310, and a rotating member 320 is installed inside the second filter tank 310. The rotating member 320 is located inside the second filter tank 310 and is connected with a primary curved screen 330, a secondary curved screen 340 and an ultimate curved screen 350 from top to bottom, and the mesh sizes of the primary curved screen 330, the secondary curved screen 340 and the ultimate curved screen 350 become smaller in sequence. Specifically, the primary curved screen 330, the secondary curved screen 340 and the ultimate curved screen 350 are respectively connected to the second filter tank 310 in a sealed and rotatable manner to prevent water from falling directly to the bottom without being filtered. After flowing into the second filter tank 310, the rotating member 320 is started to rotate the primary curved screen 330, the secondary curved screen 340 and the ultimate curved screen 350. When the water is filtered through the primary curved screen 330, the secondary curved screen 340 and the ultimate curved screen 350 in sequence, the primary curved screen 330, the secondary curved screen 340 and the ultimate curved screen 350 are rotating, thereby achieving a centrifugal effect on the water, so that the filtering effect of the water is better. Through the rotation setting of the primary curved screen 330, the secondary curved screen 340 and the ultimate curved screen 350, the water is filtered while rotating, which has a centrifugal effect, thereby improving the filtering effect of pure water.

[0033] In this embodiment, the second filter tank 310 is provided with an odor adsorbent 360 below the ultimate arc-shaped screen 350. The odor adsorbent 360 includes an activated carbon layer 361 and a supporting filter plate 362, wherein the activated carbon layer 361 is provided on the supporting filter plate 362, and the supporting filter plate 362 is connected to the inner wall of the second filter tank 310. The activated carbon layer 361 can adsorb the odor of the filtered pure water.

[0034] In the specific setting, the rotating member 320 includes a rotating motor 321 and a rotating shaft 322. The rotating motor 321 is installed on the top of the second filter tank 310. The top of the rotating shaft 322 is fixedly connected to the output end of the rotating motor 321. The bottom of the rotating shaft 322 movably passes through the top wall of the second filter tank 310 and extends to the inside of the second filter tank 310. The primary curved screen 330, the secondary curved screen 340 and the ultimate curved screen 350 are fixed to the outside of the rotating shaft 322 from top to bottom. The bottom of the second filter tank 310 is connected to the water outlet pipe. The first filter tank 210 and the second filter tank 310 are both equipped with pressure gauges. Among them, starting the rotating motor 321 causes the rotating shaft 322 to rotate, thereby causing the primary curved screen 330, the secondary curved screen 340 and the ultimate curved screen 350 to rotate.

[0035] See also Figure 1-Figure 5 , an embodiment of the present application provides a filtration system, including the above-mentioned pure water filtration structure and filtration system.

[0036] The working principle of the pure water filtration structure and filtration system:

[0037] The raw water enters the first filter tank 210 through the water inlet pipe 250 for initial stirring and filtration, and then enters the second filter tank 310 through the connecting pipe 240. After flowing into the second filter tank 310, the rotating member 320 is started to rotate the primary curved screen 330, the secondary curved screen 340 and the ultimate curved screen 350. When the water is filtered through the primary curved screen 330, the secondary curved screen 340 and the ultimate curved screen 350 in sequence, the primary curved screen 330, the secondary curved screen 340 and the ultimate curved screen 350 are rotating, thereby achieving a centrifugal effect on the water, so that the filtering effect of the water is better. Through the rotation setting of the primary curved screen 330, the secondary curved screen 340 and the ultimate curved screen 350, the water is filtered while rotating, which has a centrifugal effect, thereby improving the filtering effect of pure water. Moreover, the primary curved screen 330, the secondary curved screen 340 and the ultimate curved screen 350 are all arranged in an arc shape, which can increase the contact area with water and improve the filtering effect.

[0038] It should be noted that the specific model specifications of the drive motor 221 and the rotating motor 321 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0039] The power supply and principle of the driving motor 221 and the rotating motor 321 are clear to those skilled in the art and will not be described in detail here.
