DETAILED DESCRIPTION

[0022] refer to Figure 1 , 2 3, detailed description of the embodiment of domestic water purification:

[0023] A domestic water central purification system comprises a water inlet pipe 17 and an expansion pipe 14 fixedly connected to the lower part of the water inlet pipe 17, a connecting pipe 12 is fixedly connected to the expansion pipe 14 through a thread, a buffer pipe 11 is fixedly connected to the connecting pipe 12, a bend pipe 13 is fixedly connected to the other end of the buffer pipe 11, a purification pipe 15 is fixedly connected to the bend pipe 13 through a thread, a water outlet pipe 18 is fixedly connected to the purification pipe 15, a purifier 62 is fixedly connected to the water outlet pipe 18, and a water supply purifier 62 is fixedly connected to the water supply purifier 62. The pipe 63 is used to transport the water to be treated through the pipe, and the pipe is threadedly connected and connected to the water inlet pipe 17 to realize the continuous feeding of the water to be purified to the water inlet pipe 17. The water to be purified in the water inlet pipe 17 flows into the expansion pipe 14 for short-term storage, and then flows into the connecting pipe 12 and flows into the buffer pipe 11. The buffer pipe 11 is spiral, and the water inlet end of the connecting pipe 12 and the water inlet end of the purification pipe 15 are both located at the bottom of the buffer pipe 11, so that in the process of water flowing through the buffer pipe 11, due to the existence of the height difference The buffer tube 11 plays a buffering role. After being buffered, the water to be purified flows into the elbow 13 and then flows into the purification tube 15. A water purifying agent can be added to the purification tube 15 to purify the water to be purified. The purified water flows into the water outlet pipe 18 and then flows into the purifier 62. The purifier 62 is a product used daily in the prior art. The water is further purified and then the supply of domestic water is realized through the water supply pipe 63. The water to be purified buffered by the buffer tube 11 can flow into and out of the purification tube 15 more slowly, and can react more fully with the agent added in the purification tube 15 to ensure that the reaction is completely carried out, thereby ensuring the purification effect of the water to be purified and the safety of domestic water. A switch is provided on the elbow 13, which can control the circulation of the liquid in the elbow 13 by opening and closing the switch. It is not used as a valve for adjusting the cross-sectional area of ​​the fluid flow path in daily use, because the valve will be worn after long-term use, affecting the closing effect of the switch.

[0024] refer to Figure 2 , 3 and 4, detailing an embodiment of filtering the water to be purified:

[0025] The expansion tube 14 is rotatably connected with a push frame 21, which is provided with a plurality of spiral blades. The push frame 21 is fixedly connected to the output shaft of the reduction motor I, which is fixedly connected to the expansion tube 14. The end of the expansion tube 14 is a threaded end plate, which can be disassembled by screwing in and out of the thread, so as to clean the inside of the expansion tube 14. The reduction motor I is started, and the reduction motor I drives the push frame 21 to rotate. The push frame 21 rotates to drive the fluid to flow rapidly, ensuring the sufficient supply of the water to be purified. The end of the push frame 21 is fixedly connected with a filter plate 22 that is rotatably connected to the inner wall of the expansion tube 14. The filter plate 22 is provided with a plurality of filter holes, through which the water to be purified circulates, and through which the solids are filtered out. The filter plate 22 is away from the inner wall of the water inlet pipe 17, so as to ensure that the liquid that flows into the expansion tube 14 from the water inlet pipe 17 and then flows into the connecting pipe 12 is filtered by the filter plate 22, thereby accelerating the preliminary filtration of the water to be purified.

[0026] refer to Figure 1 , 5 8, detailed description of the embodiment of preventing impurities in the purified fluid in the purification pipe 15 from flowing into the outlet pipe 18:

[0027] The lower part of the purification pipe 15 is provided with a discharge port, and the recovery pipe 31 is rotatably connected to the discharge port. The purification pipe 15 is fixedly connected to a side plate 16 for supporting the recovery pipe 31 to rotate. The curved pipe 13 is fixedly connected to a vertical plate 33 for supporting the recovery pipe 31 to rotate. The recovery pipe 31 is fixedly connected to the output shaft of the reduction motor II, and the reduction motor II is fixedly connected to the vertical plate 33. The purification pipe 15 and the recovery pipe 31 form a purification system for loading liquid and added reagents for reaction. The precipitate generated by the reaction accumulates below the purification pipe 15 and above the recovery pipe 31. When the precipitate accumulates, the reduction motor II is started, and the reduction motor II drives the recovery pipe 31 to rotate. The recovery pipe 31 is provided with a connecting groove 32. When the connecting groove 32 is vertically upward, the sediment passes through the connecting groove 32 and falls into the recovery pipe 31 at the lower end. Then, the reduction motor II is started, and the reduction motor II drives the recovery pipe 31 to rotate until the connecting groove 32 is downward, so as to realize automatic discharge of the sediment. The recovery pipe 31 can also be rotated to a position where the connecting groove 32 is located at the upper end of the axis of the recovery pipe 31 to perform short-term storage of the sediment. The recovery pipe 31 extends into the purification pipe 15, which can also increase the contact area between the added agent and the water to be purified, and prevent the agent from sinking and accumulating below the purification pipe 15, and the accumulation of sediment affects the reaction with the water to be purified.

The outlet pipe 18 is fixedly connected with a bent frame 51, and an upper wheel 52 driving the middle wheel 43 to rotate is fixedly connected with the bent frame 51. The upper wheel 52 is fixedly connected to the output shaft of the reduction motor III, and the reduction motor III is fixedly connected to the bent frame 51. When the reduction motor III is started, the output shaft of the reduction motor III drives the upper wheel 52 to rotate, and the upper wheel 52 engages and drives the middle wheel 43 to rotate. The rotation of the middle wheel 43 drives the rotating frame 42 to rotate, and the rotating frame 42 drives the filter pipe 41 to rotate. A plurality of filter holes are processed on the filter pipe 41, and the filter holes on the filter pipe 41 can filter the liquid flowing out of the purification pipe 15, thereby ensuring the purification effect of the water to be purified.
