The setting of baffle can prevent the water inlet of water tank with strainer from impacting on filter layer directly down.Water to be filtered into It after entering water tank with strainer, first impacts on baffle, then the gap between the circumferential edge along baffle and water tank with strainer side wall is to whereabouts, Avoiding problems the direct impact filtration layers of water with pressure, play the protective effect to filter layer, extend the service life of filter layer.
Siphon stops the setting of pipe and siphon stop slot, can be after backwashing a period of time, because in siphon stop slot Water is evacuated, gas enter inclination pipeline section highest point and be automatically stopped backwash process, avoid backwash process be continued for into Row, can not restore normal filtration state automatically.
The top of siphon stop slot is lower than the junction of clear water outlet pipe and clear water reserviors, in this way in normal filtration, filtering Water afterwards can first be full of siphon stop slot, then be flowed out by clear water outlet pipe, and siphon stop slot is when ensure that normal filtration water outlet Full water state.
When siphon promotes pipe to be evacuated by highest point of the exhaust pipe to inclination pipeline section, while siphon can also be stopped in pipe Gas extraction, thus siphon stop pipe in also generate siphonage, backwash when by siphon stop slot water extract out. After the water in siphon stop slot is evacuated, large quantity of air stops the highest point that pipe is drained to inclination pipeline section by siphon, from And it destroys siphon recoil tube and its tilts the siphonage in pipeline section, and then be automatically stopped backwash process.
After the open degree for increasing regulating valve, siphon stop slot can be evacuated faster in backwash process, so as to shorten anti- Flushing process.After the open degree for reducing regulating valve, what siphon stop slot can be slower in backwash process is evacuated, to extend anti- Flushing process.

The highest point of inclination pipeline section 10 is connected with siphon and stops pipe 30, and 7 inner sidewall of clear water reserviors is connected with siphon stop slot 31, The top of 31 top of siphon stop slot opening and siphon stop slot 31 is lower than the junction of clear water outlet pipe 21 and clear water reserviors 7;It takes out Air pipe 14 preferably stops pipe 30 with siphon and is connected and is connected by siphon stopping pipe 30 with the highest point for tilting pipeline section 10.
Siphon stops the setting of pipe 30 and siphon stop slot 31, can be after backwashing a period of time, because of siphon stop slot 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 Gas extraction in 30, thus stop also generating siphonage in pipe 30 in siphon, it will be in siphon stop slot 31 in backwash Water extraction.After the water in siphon stop slot 31 is evacuated, large quantity of air stops pipe 30 by siphon and is drained to tipping tube The highest point of section 10 to destroy siphon recoil tube and its tilt the siphonage in pipeline section 10, and then makes backwash process certainly It is dynamic to stop.
The water chamber bottom sidewall is connected with discharging valve, consequently facilitating emptying maintenance.The siphon stops setting on pipe 30 There is the regulating valve for controlling backwashing time.

When work, water to be filtered passes through filter layer by intake antrum 3 by entering 1 top of water tank with strainer to drainage water inlet pipe 8 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 present invention.Even if the water level in siphon recoil tube 9 does not rise to top End opens when artificial decision is backwashed and forces flushing valve, and under to the effect of the hydraulic pressure at drainage water source, water passes through pressure punching It washes pipe 15 and enters the top that siphon promotes pipe 13, then promote to form the water flow to whereabouts in pipe 13 in siphon, to pass through pumping Air pipe 14 is forced 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, 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, in siphon recoil tube 9 Water be drawn to upwards inclination pipeline section 10 highest point, to be fallen by recoil downpipe 11 and be formed in siphon recoil tube 9 Siphonage takes away filtered water back through filter layer 4, by the impurity retained in filter layer 4 from bottom to top.Specified Backwash process was manually opened before period, can prevent set period from backwash phenomenon occurs, it can also be close to avoid filter layer Backwash process is just opened when blocking.
The above embodiments are only used to illustrate and not limit the technical solutions of the present invention, although referring to above-described embodiment to this hair It is bright to be described in detail, those skilled in the art should understand that: still the present invention can be modified or be waited With replacement, without departing from the spirit or scope of the invention, or any substitutions, should all cover in power of the invention In sharp claimed range.
