The auto-flushing cyclic process of positive flushing membrane group after a first backwash.
In the utility model, valve control unit 190 has square impact pattern and recoil pattern.Square impact pattern and recoil pattern
For two different cleaning ways.Wherein, square impact pattern is to enter the direction of water flow along raw water to carry out clearly purification membrane group 160
It washes.Under square impact pattern, raw water inlet valve 120 and straight-through water outlet valve 140 are opened.Purified water outlet valve in present embodiment
180 close.Certainly, under square impact pattern, purified water outlet valve 180 may also can be opened.Recoil pattern is enters along with raw water
Purification membrane group 160 is cleaned in the opposite direction of water flow.Under recoil pattern, raw water inlet valve 120 and purified water water outlet
Valve 180 is closed, and straight-through water outlet valve 140 is opened.
The water purification system of the utility model is described in detail below according to the water cleaning systems 100 of the embodiment shown in Fig. 1~3
The course of work of system.
Fig. 1 is referred to, when water cleaning systems 100 produce water purification, raw water inlet valve 120 and purified water outlet valve 180 are to beat
Open state, straight-through water outlet valve 140 are in off state.Raw water enters purification membrane group 160 by raw water water inlet pipe 110 first.Production
The purified water gone out is entered by purified water outlet pipe 150 in the liner 175 of pressurized tank 170, then the second pipe for passing through pressurized tank 170
The outflow of road 174 uses.It can ensure so each in use, the purified water in pressurized tank 170 must have been used first, will not retain
Stagnant water.
During 170 water storage of pressurized tank of cleaning system 100, purified water outlet valve 180 is closed, at this time due to purification membrane group 160
The hydraulic pressure of the purified water of output is more than the pressure of the air cavity 1752 of pressurized tank 170, therefore the liner 175 of pressurized tank 170 starts water storage.
When the water in water storage cavity 1762 is more and more, the air of air cavity 1752 is by crowded, then the pressure in air cavity 1752 is increasingly
Greatly.When the pressure value of the air in air cavitys 1752 reaches the pressure value of setting or maintains an equal level with water inlet pressure, can stop automatically
Stop into water, play the function of storage water, as shown in Figure 6 and Figure 7.
Fig. 3 is referred to, when cleaning system 100 carries out recoil work, valve control unit 190 is accordingly in recoil pattern.Raw water
Inlet valve 120 and purified water outlet valve 180 are closed.Open straight-through water outlet valve 140,190 meeting of the unit of valve control at this time
Raw water inlet valve 120 is momentarily closed due to the opening of straight-through water outlet valve 140, makes to form a negative pressure shape in purification membrane group 160
State.At this moment, the purified water being stored in liner 175 can be pushed back purification membrane group by the air cavity 1752 of pressurized tank 170 due to pressure change
160, form the effect of recoil module.
When the purified water for being stored in liner 175 soon drains, valve control unit 190 can be again turned on raw water inlet valve 120, shape
Into positive die set, valve control unit 190 is accordingly in square impact pattern.At this point, raw water flows through raw water water inlet pipe 110 to purification membrane group
160 are just rinsed, and are led directly to water later and are discharged from straight-through water outlet pipe 130, as shown in Figure 2.
Furthermore, it is necessary to illustrate, in the water cleaning systems of the utility model, the number of filter core is not limited in purification membrane group
This, the number of filter core also can be one or several.It, can also between several filter cores when the number of filter core is several
It is combined to connect or connecting in parallel, forms more perfect cleaning system..
Refer to Fig. 8, in the water cleaning systems 200 of another embodiment, purification membrane group 260 includes the filters of three series connection
Core is followed successively by the first filter core 261, the second filter core 262 and third filter core 263 from left to right.First filter core of present embodiment
261st, the second filter core 262 and third filter core 263 are respectively active carbon filter core, active carbon filter core and ultra-filtration element.Certainly, filter core
Material is without being limited thereto, can also be the combination of other materials.For example, it is followed successively by PP cotton filter cores, PP cotton filter cores and ultra-filtration element.
In this embodiment, the water inlet end of the first filter core 261 is connected with raw water water inlet pipe 210, the first filter core 261
Water outlet be connected with the water inlet end of the second filter core 262, the water outlet of the second filter core 262 and the water inlet end of third filter core 263
It is connected.The water outlet of third filter core 263 is connected respectively with straight-through water outlet pipe 230, purified water outlet pipe 250.
When water cleaning systems 200 produce water purification work, when raw water flow to purification membrane group 260, from left to right followed by these three
The filter core 262 of series connection, later purified water flowed out from purified water outlet pipe 250, straight-through water is discharged from straight-through water outlet pipe 230.
The water cleaning systems of the utility model, under recoil pattern, since raw water inlet valve and purified water outlet valve are closed, only
Change and a negative pressure state is formed in film group, therefore, the air cavity of pressurized tank is due to pressure change, the purification hydraulic pressure that can will be stored in liner
Purification membrane group is returned, is recoiled.Under square impact pattern, since raw water inlet valve and straight-through water outlet valve are opened, therefore raw water flows through
Raw water water inlet pipe is just rinsing purification membrane group, leads directly to water later and is discharged from straight-through water outlet pipe.Therefore, the utility model
Above-mentioned water cleaning systems can realize positive repercussion effect, complete cleaning function, can increase the service life of filter core.
In addition, in the water cleaning systems of the utility model, the first pipeline and the second pipeline of pressurized tank be respectively used into water or
Person is discharged, it is ensured that the water in pressurized tank is all circulated, and the inside of pressurized tank is avoided to form stagnant water and grow bacterium, makes people
Health be protected.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, it is all considered to be the range of this specification record.
Embodiment described above only expresses the several embodiments of the utility model, and description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent range.It should be pointed out that the common skill for this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
