Water in 31 is evacuated, gas enters inclination 10 highest point of pipeline section and is automatically stopped backwash process, avoids backwash process one
Straight lasting progress, can not restore normal filtration state automatically.
The top of siphon stop slot 31 is lower than the junction of clear water outlet pipe 21 and clear water reserviors 7, in this way in normal filtration,
Filtered water can first be full of siphon stop slot 31, then be flowed out by clear water outlet pipe 21, siphon when ensure that normal filtration water outlet
Stop slot 31 is full water state.
When siphon promotes pipe to be evacuated by highest point of the exhaust pipe to inclination pipeline section 10, while also siphon can be stopped managing

4 enter water chamber 5, and when passing through filter layer 4, water to be filtered is filtered by filter layer 4, and the impurity in water is trapped within filter layer
At 4；Filtered water purification enters clear water reserviors 7 by water pipe 6 by water chamber 5, flows out eventually by clear water outlet pipe 21.
If in long-term work, the impurity that filter layer 4 retains is more and more, filter layer 4 without manual control
Filtration resistance is increasing, and the water level in siphon recoil tube 9 gradually rises with 4 being gradually increased for filtration resistance of filter layer.When siphon is anti-
When waterborne in washing pipe 9 rises to top, water first promotes pipe 13 to fall by siphon, and water generates drainage when to falling, by rainbow
Inhale the air extraction in accelerating tube 19.Since the hydraulic pressure in high-order aeration water tank 20 is higher, and the caliber of siphon accelerating tube 19 is small
Promote pipe 13 in siphon, and siphon promotes the caliber of pipe 13 less than a quarter of the caliber of siphon recoil tube 9, therefore siphon adds
Gas in fast pipe 19 can relatively very be easy emptying, and then can be easily created siphonage.Shape in siphon accelerating tube 19
After siphonage, a high position aeration water tank 20 in water continually by siphon accelerating tube 19 enter siphon promote pipe 13 and under
It falls, and then improves the drainage to exhaust pipe 14.Air accumulation in siphon recoil tube 9 is in the highest for tilting pipeline section 10
Place, in the case where siphon promotes in pipe 13 under overboard drainage, the gas for tilting the highest point of pipeline section 10 passes through exhaust pipe 14
It is downwardly into siphon accelerating tube 19 and is discharged into recoil discharge casing 2.When the gas of the highest point of inclination pipeline section 10 is taken out to the greatest extent, in rainbow
It inhales in recoil tube 9 and is formed siphonage.The caliber of siphon recoil tube 9 is thicker, thus the water flow to recoil is larger, crosses drainage
Filtered water can also flow back to back through the water in filter layer 4(clear water reserviors 7 from bottom to top in case 1), it will be in filter layer 4
The impurity of retention is taken away, and cleaned filtering layer 4 is played the role of.Filter layer 4 after backwash is regenerated, and can be carried out again just
Normal filtration.
Previous homogeneous system cannot manually open backwash process, and the water level in siphon recoil tube 9 can only be waited to rise to
Top, the filtration resistance of filter layer 4 is very big at this time, not can be carried out normal filtration.
Backwash process then can be manually opened using the utility model.Even if the water level in siphon recoil tube 9 does not rise
It to top, when artificial decision is backwashed, opens and forces flushing valve, under to the effect of the hydraulic pressure at drainage water source, water passes through by force
Flushing pipe 15 processed enters the top that siphon promotes pipe 13, then promotes to form the water flow to whereabouts in pipe 13 in siphon, thus logical
Exhaust pipe 14 is crossed to force to take away the gas for tilting the highest point of pipeline section 10.Since recoil 11 lower end of downpipe is by water seal,
Therefore negative pressure is formed in siphon recoil tube 9.As the gas of the highest point of inclination pipeline section 10 is constantly taken away, siphon recoil tube
Water in 9 is drawn to the highest point of inclination pipeline section 10 upwards, to be fallen by recoil downpipe 11 and the shape in siphon recoil tube 9
At siphonage, take away filtered water back through filter layer 4, by the impurity retained in filter layer 4 from bottom to top.Referring to
Backwash process is manually opened before timing section, can prevent set period from backwash phenomenon occurs, can also be connect to avoid filter layer
Backwash process is just opened when nearly blocking.
