Sand filter tank 2, activated carbon filter tank 4, the upper head is a clamp seal, the filler filter material can be filled with bulk material, and at the same time can be filled with sintered rod-shaped filter material φ60×110mm.

The working principle of the drinking water purifier of the utility model is: in the initial state of device operation, tap water first enters the raw water tank 1, and the raw water tank 1 is in the state of full water, and the manual recoil multi-way valve 3-1 on the upper part of the sand filter tank 2 Rotate the handle of the handle to the recoil state, start the raw water pump 33 and run for 5 minutes, and the recoil water is discharged by the recoil blowdown pipe 6. Then the handle of the manual recoil multi-way valve 3-1 is rotated to the normal state, the sand filter tank drain valve 32 is opened at the bottom of the sand filter tank 2, and the raw water pump 33 is started for 5 minutes. Then the handle of the manual recoil multi-way wide 3-2 on the activated carbon filter tank 4 top is rotated to the recoil state, and the raw water pump 33 was started to run for 10 minutes, and the recoil water was discharged by the recoil drain pipe 6. Then turn the handle of the manual recoil multi-way valve 3-2 to the normal state, open the activated carbon filter tank drain valve 31 at the bottom of the activated carbon filter tank 4, and then start the raw water pump 33 to run for 10 minutes, and then proceed in order to start the high pressure pump 29. The raw water enters the clean water tank 18 through the sand filter tank 2, the activated carbon filter tank 4, the fine filter tank 5, the water quality regulator 9, the nanofiltration membrane module 12, and the ultraviolet sterilizer 27. When the water level reached the upper limit water level controller 19, the high-pressure pump 29 stopped, and the raw water pump 33 delayed operation for 1 minute, and at this moment, the water site used water. The pressure sensor 22 at the water point is set to a constant pressure operating point, and the pressure sensor 22 controls the constant pressure operation of the water pump through the frequency converter of the electric control box 35 . When the clean water tank 18 continuously delivers water to the water point along with the water supply pump 24, and when the water level drops to the lower limit water level controller 25 of the clean water tank 18, the electric control box 35 starts the raw water pump 33 and runs for 1 minute. High pressure pump 29 starts subsequently, and whole device makes water again. When the lower limit water level controller 25 of the clean water tank 18 failed, the lower limit water level controller 25 sent a signal to shut down the whole device. When tap water is cut off, the former water tank 1 is evacuated, and the lower limit water level controller 34 of the former water tank reports to the police and sends a control signal, and the whole device is shut down. After the whole device has been in operation for a period of time, the filter material of each part is polluted and must be cleaned. The sand filter tank 2, the activated carbon filter tank 4, and the fine filter tank 5 can be backwashed. Backwash the sand filter tank 2, turn the manual recoil multi-way valve 3-1 on the upper part of the sand filter tank 2 to the recoil state, start the raw water pump 33, and the recoil sewage enters the recoil sewage pipe 6 to be discharged; the activated carbon filter tank 4 backwashes , turn the upper part of the activated carbon filter tank 4 to the manual recoil multi-way width 3-2 to the recoil state, start the raw water pump 33, and the recoil sewage enters the recoil sewage pipe 6; the backwash process of the fine filter tank 5 is the same as that of the sand filter tank 2 . Nanofiltration membrane module 12 cleaning needs to carry out surface cleaning with chemical preparation, and method is that the water inlet electromagnetic valve 7 before high-pressure pump 29 is closed. Open the cleaning return valve 28, inject a certain volume of cleaning solution mixed with clean water into the clean water tank 18, start the high-pressure pump 29, and the cleaning solution enters the nanofiltration membrane module 12 to rinse the membrane surface, run for 10 minutes, and stop the high pressure Pump 29, after the cleaning solution is soaked in the nanofiltration assembly 12 for 20 minutes. Start the high pressure pump 29 again. The stop and start process is repeated 5-10 times to complete the chemical cleaning, close the return water cleaning valve 28, open the high-pressure pump 29, the water inlet solenoid valve 7, empty the clean water tank 18, and then inject clean water to rinse the clean water tank for many times 18, the entire cleaning process can be completed.

Compared with the prior art, the utility model has the advantages that: because the device adopts sand filtration, activated carbon filtration, and precision filtration to remove suspended solids, colloids, bacteria, organic matter and other particles in the water, the water quality regulator 9 can change the water quality. The molecular arrangement structure makes the molecular clusters into small molecular bodies, which makes the water active and easy for the human body to absorb. The nanofiltration membrane screens water molecules at the molecular level, allowing water molecules and ions less than 200 to pass through, intercepting heavy metals and salts with a divalent price or more, organic matter, viruses, bacteria and other substances that are toxic and harmful to the human body. Minerals and trace elements beneficial to the human body are retained in the water. After being purified by these processes, it is finally sterilized by an ultraviolet sterilizer to ensure that the purified water tastes pure, hygienic and safe, and can be drunk directly.

All tank containers of the device are quick-installed and clamp-sealed so that users can open the sand filter tank, activated carbon filter tank and fine filter to fill the filter material. Bulk filter material or rod filter material can be used, which is very convenient during use, and the use and maintenance are people-oriented, safe and practical.

The device supplies water to the water point, adopts frequency conversion speed regulation water supply mode, constant pressure variable, energy saving, high efficiency, and can run stably for a long time. All parts of the device are integrated and installed on a frame, with compact structure, complete functions, convenient and fast, practical and efficient, safe and reliable, small footprint, saving investment and convenient maintenance.
