5: the water to fine filtering device recoil filter core carries out recycling.

The purpose of this utility model realizes by taking following measure:

1: the method that the utility model is taked " concentrate with the processing of branch family and combine ", realize the sub-district quality classification water supply." concentrate with dividing the family and handle " water treatment technology and the way of supplying water of method, as shown in Figure 2.As seen from Figure 2:

The utility model at first adopts the essence filter unit group MF (N) with automatic recoil filter core in service, tap water concentrated carry out secondary filter, to remove silt rust in the water etc., make tap water become clear, and be stored among the filtered water tank Q1, then by constant pressure frequency conversion pump Q2 and clear water pipe network Q0, clear water is transported in the man of resident family of sub-district, every family can be taken clear water by the leading QN of oneself clear water at any time, for laundry, have a bath the use of flushing the toilet.Then by the collection active carbon, the ultrafiltration water treatment technology is obtained the high-quality water purification in the terminal water treatment unit UF of one to neighbours living at any time, for infusing tea the use of cooking.The water treatment technology of method and the device of way of supplying water " are concentrated with the processing of branch family and are combined " in described employing, realized two purposes of the present utility model: once being only can realize the quality classification water supply of sub-district with a pipe network Q0: it can provide to the neighbours living unification and have a bath, laundry, the clear water of flushing the toilet and using, can provide drink water easily by the after-treatment of every family again to clear water; The 2nd, the chlorine in the tap water has been saved in the end of clear water water transfer pipe network Q0, so need not in the process of transporting water, to install additional again ozone sterilization device B7.

2: for filter core with cavity structure, when water by its external surface when its inner surface flows, be the external pressure working method, the abbreviation external pressure.When water by its inner surface when its external surface flows, be interior pressure working method, pressure in being called for short.Press filtration water beyond the utility model is with interior pressure recoil filter core.

Overcome the best approach that fine filter B4 filter core can not clean this weakness, be to be in operation with its self-produced clear water, come its filter core of back flush, reaching this purpose must solve two problems: the one, and be transformed into fine filter B4 and have two the antipodal water route of water (flow) direction structures, and the opposite water route of these two water (flow) directions is wanted and can be changed automatically; The 2nd, the self-produced clear water of recoil filter core should remain certain pressure.

Have two antipodal water routes of water (flow) direction, and can the be in operation essence of automatically conversion of the opposite water route of these two water (flow) directions is filtered single MF such as Fig. 3 A, shown in Fig. 3 B: described smart filter unit MF is by a fine filter B4, energy is organized the two-bit triplet diaphragm valve K1 in the fully opposite water route of two water (flow) directions for fine filter B4, can control two-bit triplet electromagnetic valve K2 that diaphragm valve K1 opens and closes two different water routes automatically and links to each other and form with one.

Fig. 3 A has shown smart filter unit MF, water (flow) direction and path when tap water is carried out secondary filter by the external pressure mode, and this moment, two-bit triplet electromagnetic valve K2 linked up the path between pipeline 13 and the pipeline 14 under the control of circuit control unit K3.Because pipeline 13 links to each other with the intake-outlet 10 of two-bit triplet diaphragm valve K1 control chamber 9, the release downstream of pipeline 8 of pipeline 14 and the recoil water of two-bit triplet diaphragm valve K1 links to each other, so, in the control chamber 9 when if water is arranged, extruding when these water will be eliminated deformation because of the diaphragm of rubber 11 that is subjected to two-bit triplet diaphragm valve K1, release in the lower channel of pipeline 8 and be discharged into recoil water, the opposing party is because the elimination of diaphragm of rubber 11 deformation, diaphragm of rubber 11 has been closed the release water inlet of pipeline 8 of recoil water, meanwhile two-bit triplet diaphragm valve K1 is with fine filter B4, for essence filter unit MF has organized a path of producing clear water shown in Fig. 3 A: the tap water after the pressurization by water inlet pipe 5 successively through the water inlet pipe 6 of diaphragm valve K1, the outlet pipe 7 of diaphragm valve K1, the water inlet duct 18 of fine filter B4 is in the lauter tub 16 of fine filter B4, this moment tap water by self pressure by the external surface of filter core 17 to inner surface movement, meanwhile, silt rust in the water etc. are stopped the extexine at filter core 17, after tap water after becoming clearly enters the cavity of filter core 17, by filtering the water outlet duct of covering on 15 19, water inlet pipe 20 by clear water cylinder 21, enter in the clear water cylinder 21, thereby finish the water treatment technology that tap water is become clear water incessantly.

Fig. 3 B has shown the clear water of smart filter unit MF in the clear water cylinder 21, water (flow) direction and path when filter core 17 is carried out backwash, this moment is under the control of circuit control unit K3, two-bit triplet electromagnetic valve K2 has linked up the path between pipeline 12 and the pipeline 13, since pipeline 12 with the pressurization after tap water supply pipeline 5 link to each other, pipeline 13 links to each other with the intake-outlet 10 of two-bit triplet diaphragm valve K1 control chamber 9, so tap water in the tap water water inlet pipe 5, will be by the pipeline 12 of two-bit triplet electromagnetic valve K2 communication, pipeline 13 enters in the control chamber 9 of diaphragm valve K1, because diaphragm of rubber 11 is subjected to the pressure area of water in control chamber 9, times over the pressure area that be subjected to water of diaphragm of rubber 11 in control chamber 9 outsides, so what diaphragm of rubber 11 was subjected to makes a concerted effort, to oppress diaphragm of rubber 11 deformation will take place downwards, so diaphragm of rubber 11 has been closed the exhalant canal of two-bit triplet diaphragm valve K1 water inlet pipe 6, meanwhile, opened the water inlet of the recoil water Outlet Pipe 8 of two-bit triplet diaphragm valve K1, so two-bit triplet diaphragm valve K1 is with fine filter B4, for fine filtering device MF has organized shown in Fig. 3 B with the self-produced clear water in the clear water cylinder 21, by the path of interior pressure mode back flush filter core 17 external surface dirts: the clear water in the clear water cylinder 21 is successively through the water inlet pipe 20 of clear water cylinder 21, filter the cavity that the delivery port 19 that covers on 15 enters filter core 17, pressure by water storage in the clear water cylinder 21, clear water will be from the outside apparent motion of the inner surface of filter core 17, carrying the dirts such as silt rust that brush down by the recoil of filter core 17 external surfaces this moment in the clear water secretly, successively through lauter tub 16, the water inlet 18 on 15 is covered in filter, the outlet pipe 7 of two-bit triplet diaphragm valve K1, recoil Outlet Pipe 8 by two-bit triplet diaphragm valve K1 is released, thereby the dirt under incessantly the filter core external surface being held back recoils.

Allow measure that the self-produced clear water of recoil filter core keeps certain pressure as shown in Figure 4, N (N＞2, N=3 in the present embodiment) independently smart filter unit MF is connected in parallel, forms a smart unit group MF (N) of filter; Each essence is filtered the clear water that unit MF is produced, be stored in earlier in the clear water cylinder 21, and take the way of current limliting, allow and flow into the water yield in the clear water cylinder 21 in the unit interval, greater than by the water yield that flows in the clear water cylinder 21 among the clear water water tank Q1, and under the control of circuit control unit K3, only allow a smart filter unit MF among the smart filter unit group MF (N) to recoil at one time, the time of in addition recoiling is very short, so clear water in the clear water cylinder 21, can remain the intake pressure that is slightly less than clear water cylinder 21, and this pressure enough is used for the filter core that recoils.

After taking above-mentioned measure, just realized the 3rd purpose of the present utility model: the structure of transforming fine filter B4, make it have the function of recoil filter core automatically that is in operation, made a clean sweep of filter core too early by the sorrow of the suspension obstruction of bulky grain shape, so sand filter B2 has lost the necessity that exists, and has realized the 3rd purpose of the present utility model.

Three: the clear water of registering one's residence further is processed into the terminal water treatment unit UF of drink water, as shown in Figure 5.The filtering accuracy of the ultrafiltration filter core U5 of terminal water treatment unit UF is the 0.3---0.05 micron, and adds active carbon U6 in its cavity.Terminal water treatment unit UF is actually authorized the 01267890 No. 2 patent of the utility model applicant, the application in the utility model.As seen from Figure 5: ultrafilter U3 passes through normally open solenoid valve U1, normally closed solenoid valve U2, and high-quality clear water faucet U13 and recoil water tap U14 under the control of the mobile direction sensor U9 of water, have two water routes that water (flow) direction is opposite.Unit UF is in closed condition in the terminal water treatment, be that high-quality clear water faucet U13 and recoil water tap U14 are when being in closed condition, the float U12 of the mobile direction sensor U9 of water is high-end because of buoyancy of water is in, and disconnects the parallel circuit of normally open solenoid valve U1 and normally closed solenoid valve U2:

1: this moment is if open the words of high-quality water purification water tap U13, registering one's residence clear water just can be by clear water pipe network Q0 successively through normally open solenoid valve U1, ultrafilter external pressure water inlet U7, enter in the ultrafilter filter housing U4, by clear water self pressure, clear water will be by the external surface of filter core U5 to its inner surface movement, the pathogenic thing of bacterium etc. this moment is stopped, and the water of bacterium that flowed into removal in the filter core U5 cavity, then carried out dechlorination by active carbon, go halid processing, then by the external pressure delivery port U8 of ultrafilter through line transportation to high-quality water purification water tap U13, flow out and use for the user.

2: this moment is if open the words of recoil water tap U14, the float U12 of water (flow) direction sensor U9 will be pressed onto the bottom by current, and the parallel circuit of connection normally open solenoid valve U1 and normally closed solenoid valve U2, so terminal water treatment unit UF will be by the interior pressure mode ultrafiltration filter core U5 that recoils, as long as do not need combine the opportunity of high-quality water with doing health etc., just can realize the recoil water reuse recoil filter core.The high-quality clear water faucet U13 of water treatment unit as long as obviously open a terminal, just having endlessly, drink water flows out, for infusing tea, use such as cook, and open clear water tap QN at any time, and just having for laundry, the clear water of the uses such as flushing the toilet of having a bath flows out, so far adopt and concentrate the utility model of handling the method that combines with the branch family, just realized single tube net sub-district quality classification water supply.Flushing the toilet with clear water, some is not proper, but the processing cost of clear water is very low, and the ratio that accounts for domestic water consumption is also little, and is also just insignificant with the huge shortcoming of two-tube net quality classification water supply relatively.

Four: the recoil unit for treating water DF that the water of essence filter unit group MF (N) recoil filter core is carried out recycling, as shown in Figure 6.Its will recoil earlier water of filter core is collected in the recoil water tank 26, utilizes again by dual mode then, and the one, by the artificial opening/shutting valve 32 recoil water of releasing, preferentially satisfy subdistrict greening, clean the water of a class; The 2nd, to the recoil water of part more than needed, by the recoil water tank 26 of come-up filtrate 34 is housed, after last ability of swimming filters, adopt press over system to import pond 2 from the beginning again, thereby realized the 5th purpose of the present utility model: the water to the recoil filter core carries out recycling.

The specific embodiment

The utility model is taked the method for " concentrate with the processing of branch family and combine ", realize single tube net sub-district quality classification water supply, and to the recoil filter core water carry out recycling, the utility model is formed a complete system by three complementary functions, these three functions are respectively:

1: tap water is focused on into clear water, and the function of delivering to producing of sub-district every family and carrying clear water with pipeline.

2: every family carries out after-treatment separately to the clear water of registering one's residence, to obtain the function of drink water.

3: the function that the smart filter recoil water that filter core produced that recoils is carried out recycling.

Water-saving single pipe network sub-district divided water supply device shown in Figure 4 is described in detail in detail below, is how to realize above-mentioned three functions:

One: concentrate and produce and carry clear water

Realize to concentrate and to produce and to carry the clear water operating principle as shown in Figure 4: it has three kinds of duties, promptly shuts down, and produces and carries clear water and produce in the clear water process automatic recoil to filter core.

1: shut down

When clear water pipe network Q0 output is zero; constant pressure frequency conversion pump Q2 shuts down automatically; clear water among the clear water water tank Q1 has does not at this moment have; and water level is raise; when water level attained to a high place, water level switch Q3 cut off the circuit of tap water force (forcing) pump 3 and it is shut down, so under the control of circuit control unit K3; stop to produce and carrying clear water, the process of once making water and conveying finishes.

2: produce and carry clear water:

When clear water pipe network Q0 output changes nought state, constant pressure frequency conversion pump Q2 starts operation automatically, clear water among the clear water water tank Q1 has the nothing of going out and then makes drawdown at this moment, when dropping to low water stage, water level switch Q3 connects the circuit of tap water force (forcing) pump 3, and with constant pressure frequency conversion pump Q2 run-in synchronism, meanwhile under the control of circuit control unit K3, the new technological process of once producing and carrying clear water begins.As shown in Figure 4: the sub-district tap water in the pond 2 from the beginning enters in the tap water supply cylinder 4 after force (forcing) pump 3 pressurizations, and tap water supply cylinder 4 will guarantee that each the essence in essence filter unit group MF (N) filters unit MF and all press water supply.Tap water in the tap water supply cylinder 4 is through tap water supply pipe 5, enter in the water inlet pipe 6 of two-bit triplet diaphragm valve K1 of smart filter unit MF, under the control of circuit control unit K3, the path that two-bit triplet electromagnetic valve K2 connection pipeline 13 and pipeline are 14, and cause no hydraulic pressure in the control chamber 9 of two-bit triplet diaphragm valve K1, cause the diaphragm of rubber 11 of two-bit triplet diaphragm valve K1, close the release water inlet in duct 8 of recoil water, and link up the path of 7 of water inlet pipe 6 and outlet pipes, thereby formed an expressed path of producing and carry clear water of Fig. 3 A and Fig. 4: the tap water in the pond 2 is after force (forcing) pump 3 pressurizations from the beginning, successively through tap water supply cylinder 4, tap water supply pipe 5, the water inlet pipe 6 of two-bit triplet diaphragm valve K1, the outlet pipe 7 of two-bit triplet diaphragm valve K1, the water inlet duct 18 of fine filter B4, and enter in the lauter tub 16 of fine filter B4, this moment, tap water was by self pressure, by the external surface of filter core 17 to inner surface movement, meanwhile the silt rust in the water etc. is stopped the external surface at filter core 17, become clear tap water successively through the cavity of filter core 17, the delivery port duct 19 on 15 is covered in filter, the water inlet pipe 20 of clear water cylinder 21, clear water cylinder 21, clear water outlet pipe QQ, enter clear water water tank Q1, and after constant pressure frequency conversion pump Q2 with clear water suction clear water pipe network Q0, so neighbours living can be taken clear water by clear water water tap QN at any time.As long as the output of clear water pipe network Q0 is non-vanishing, above-mentionedly produce and carry the technological process of clear water more than.

3: produce the filter of recoil essence automatically filter core in the clear water process

Produce and carry in the clear water technological process smart filter unit group MF (N) to produce clear water, produce in the clear water essence filter filter core is carried out back flush, all under the control of circuit control unit K3, carry out automatically, so the utility model device is before coming into operation, controlling parameter should be set among the circuit control unit K3 in advance, the most basic parameter of circuit control unit comprises: each smart filter unit MF of start T0 that how long turns round respectively again each time, beginning is recoil for the first time, for the first time after the recoil, each smart filter unit MF T1 that how long turns round carries out new once recoil; And the time T 2 of each recoil.

For example: three smart filter unit MF from left to right among present embodiment Fig. 4, if turned round 3 fens respectively, 4 minutes, carried out new once recoil in 5 minutes, then T0=(3,4,5), if new once recoil, then T1=5 were carried out in the every running of each smart filter unit MF later in 5 minutes, if each recoil 6 seconds, then T2=0.1; These controlling parameter are set among the circuit control unit K3 in advance, and from left to right three smart filter unit MF among that the one embodiment shown in Figure 4 pick up counting from the new clear water of once producing, and recoil of each smart filter unit MF is opportunity:

1 MF:3 8.06 13.12 is played on a left side ... (branch)

2 MF:4 4.06 14.12 is played on a left side ... (branch)

3 MF:5 10.06 15.12 is played on a left side ... (branch)

Obviously at any one time, among the smart filter unit group MF (N), there is a smart filter unit MF that essence filter filter core 17 is being carried out back flush at most.When some smart filter unit MF run to reply filter core 17 and carry out new once recoil, circuit control unit K3 just controls two-bit triplet electromagnetic valve K2 and carries out such operation: two-bit triplet electromagnetic valve K2 by the water route between line of communication 13 and the pipeline 14, become the water route between line of communication 12 and the pipeline 13, so just formed shown in Fig. 3 B with the clear water that has certain pressure in the clear water cylinder 21, the water route that filter core 17 is carried out back flush: because pipeline 12 links to each other with tap water supply pipeline 5 after the pressurization, pipeline 13 links to each other with the intake-outlet 10 of two-bit triplet diaphragm valve K1 control chamber 9, so tap water in the tap water water inlet pipe 5, will be by the pipeline 12 and the pipeline 13 of two-bit triplet electromagnetic valve K2 communication, enter in the control chamber 9 of diaphragm valve K1, because the pressure area that be subjected to water of diaphragm of rubber 11 in control chamber 9, times over the pressure area that be subjected to water from water inlet pipe 6 of diaphragm of rubber 11 in control chamber 9 outsides, so deformation takes place downwards in the diaphragm of rubber 11 of will oppressing with joint efforts that diaphragm of rubber 11 is subjected to, so diaphragm of rubber 11 has been closed the exhalant canal of two-bit triplet diaphragm valve K1 water inlet pipe 6; Meanwhile, opened the water inlet of the recoil water Outlet Pipe 8 of two-bit triplet diaphragm valve K1, so two-bit triplet diaphragm valve K1 is with fine filter B4, for fine filtering device MF has organized shown in Fig. 3 B with the self-produced clear water that is stored in the clear water cylinder 21, by the path of interior pressure mode back flush filter core 17 external surface dirts: the clear water in the clear water cylinder 21 is successively through the water inlet pipe 20 of clear water cylinder 21, the delivery port 19 on 15 is covered in filter, enter the cavity of filter core 17, by the pressure in the clear water cylinder 21, clear water will enter lauter tub 16 from the outside apparent motion of the inner surface of filter core 17, the dirts such as silt rust that brush down by the recoil of filter core 17 external surfaces have been carried this moment in the clear water secretly, successively through filtering the water inlet 18 that covers on 15, the outlet pipe 7 of two-bit triplet diaphragm valve K1, then release, thereby the dirt of finishing incessantly the filter core external surface is former under holding back carries out back flush by the recoil water Outlet Pipe 8 of two-bit triplet diaphragm valve K1.After the recoil time equals predefined recoil time T 2, circuit control unit K3 just controls two-bit triplet electromagnetic valve K2 and carries out such operation: two-bit triplet electromagnetic valve K2 by the water route between line of communication 12 and the pipeline 13, become the water route between line of communication 13 and the pipeline 14, so water in the two-bit triplet diaphragm valve K1 control chamber 9, will be because of losing the hydraulic pressure support of tap water supply pipe 5, in this simultaneously, the diaphragm of rubber 11 of pressurized deformation, to eliminate deformation because of the disappearance of pressure, eliminate under the pressure effect that deformation produced at diaphragm of rubber 11, diaphragm of rubber 11 is closed the water inlet of the recoil water Outlet Pipe 8 of two-bit triplet diaphragm valve, then link up the water inlet pipe 6 of two-bit triplet diaphragm valve K1 and the water route between the outlet pipe 7, so once recoil finishes, and the new flow process of once producing clear water begins.According to system water, recoil, system water, the treatment process of recoil, circulation is more than, when the output that directly ends clear water pipe network Q0 is zero, once produces the process of carrying clear water and finishes.

Two: the high-quality water purification is produced at the branch family

The clear water of registering one's residence is carried out ultrafiltration and charcoal treatment, provide for neighbours living drink water terminal water treatment unit UF structural representation as shown in Figure 5.Terminal water treatment unit UF has three kinds of duties, promptly closes, and takes high-quality water purification and recoil ultrafiltration filter core.

1: close

As the high-quality clear water faucet U13 of terminal water treatment unit UF, when recoil water tap U14 closed, terminal water treatment unit stopped processing to the clear water of registering one's residence because of anhydrous output, and is in closed condition.This moment, the water switch U12 of direction sensor U9 that flows because of surplus buoyancy of water in managed is in high-endly, and cut off the normally open solenoid valve U1 that is connected in parallel and the circuit of normally closed solenoid valve U2.

2: take the high-quality water purification

At any time open the high-quality clear water faucet U13 of the terminal water treatment unit UF under the closed condition, just have the high-quality water purification of producing by the external pressure working method to flow out continuously, when closing high-quality clear water faucet U13, end.When being in closed condition, the water (flow) direction sensor U9 of terminal water treatment unit UF cuts off normally open solenoid valve U1, the parallel circuit of normally closed solenoid valve U2, this moment, left in the water route of normally open solenoid valve U1, close in the water route of normally closed solenoid valve U2, so when opening high-quality water purification water tap U13, terminal water treatment unit UF has just opened a path of producing the high-quality water purification by the external pressure working method, be that clear water among the clear water pipe network Q0 is by normally open solenoid valve U1, ultrafilter external pressure water inlet U7 is in ultrafilter filter housing U4, by clear water self pressure, clear water is flowed to its inner surface by the external surface of ultrafiltration filter core U5, meanwhile dirt such as bacterium is retained in the external surface of ultrafiltration filter core U5, and enter water in the cavity of ultrafiltration filter core U5, undertaken after dechlorination and halide handles by active carbon, introduce high-quality water purification water tap U13 by the external pressure delivery port U8 of ultrafilter U5 through pipeline and flow out continuously, till high-quality water purification water tap U13 closes.

3: recoil ultrafiltration filter core

At any time open the recoil faucet water U14 of the terminal water treatment unit UF under the closed condition, just have by interior pressure mode the water that the ultrafiltration filter core carries out back flush is flowed out, when closing recoil faucet water U14, end.When being in closed condition, the mobile direction sensor U9 of the water of terminal water treatment unit UF cuts off normally open solenoid valve U1, the parallel circuit of normally closed solenoid valve U2, this moment, left in the water route of normally open solenoid valve U1, close in the water route of normally closed solenoid valve U2, so when opening recoil faucet water U14, to need following two steps, could allow terminal water quality treater UF open one by the recoil path of ultrafiltration filter core of interior pressure mode: the first step is to fling the flow water inlet pipe U10 of direction sensor U9 of water by the clear water among the clear water pipe network Q0 through normally open solenoid valve U1, this strand clear water is pressed onto low side with sensor floating device switch U12, and be guided to recoil faucet water U14 by sensor outlet pipe U11 and flow out, meanwhile, to carry out for second step automatically, promptly because sensor floating device switch U12 is pressed onto the bottom by first strand of clear water, and the parallel circuit of connection normally open solenoid valve U1 and normally closed solenoid valve U2, so the water route of normally open solenoid valve U1 is reversed to the pass by opening, the water route of normally closed solenoid valve U2 then is reversed to out by the pass, so one open-minded by the recoil water route of ultrafiltration filter core of interior pressure mode: promptly clear water is by clear water pipe network Q0 warp successively: normally closed solenoid valve U2, ultrafilter external pressure delivery port U8 enters in the cavity of ultrafiltration filter core U5, by self pressure, clear water is from the outside Surface runoff of inner surface of ultrafiltration filter core U5, and through the external pressure water inlet U7 of ultrafilter, the water inlet pipe U10 of sensor, the outlet pipe U11 of sensor, recoil faucet water U14 releases, the water of releasing is then being carried the dirt that is retained in ultrafiltration filter core U5 external surface secretly, the process of this recoil ultrafiltration filter core will stop along with closing of recoil faucet water U14, because recoil faucet water U14 closes, the hydraulic pressure that sensor floating device switch U12 is subjected to disappears, and float in high-end, make terminal water treatment unit UF recover closed condition again.

Three: the recycling of recoil water:

To the water of essence filter unit group MF (N) recoil filter core, carry out recycling recoil unit for treating water DF structure as shown in Figure 6.The recoil unit for treating water water that at first will recoil is collected the water tank 26 that recoils, utilize again by dual mode then: the one, preferentially be used for subdistrict greening, cleaning, the 2nd, by being installed in the last floating filtrate 34 in the recoil water header tank 26, the mode with overflow after last ability of swimming filters comes back to pond 2 from the beginning, sub-district.Recoil unit for treating water DF has three kinds of duties:

1: the collection of recoil water, flushing filtrate and precipitation

When the circuit control unit K3 of essence filter unit group MF (N) sends for some smart filter unit MF to recoil control signal; it has started recoil water suction pump 23; so recoil water in the recoil water header 22; add the water in the recoil water tank 26 that transports by 36 li of water-supply-pipes; the top that will import back flushing tank through the outlet pipe 24 of suction pump 23 is spouting; meanwhile the dirt attached to last floating filtrate 34 surfaces will be cleaned; and after suction pump 23 is shut down, be deposited to the bottom of recoil water tank gradually.

2: the use of recoil water, filtrate cleans and blowdown

Work as greening, when doing health and needing water, only need open recoil penstock 32, the impeller machine 29 that differential automatic pump 28 and circuit are connected in parallel with it starts simultaneously, stirred by impeller machine so be deposited in the dirt of bottom, the filtrate that is in top also stirs current because of impeller machine, and makes its dirt of holding back separate sinking with it, and this mixed water will be delivered to the valve of opening 32 by differential automatic pump 28, release greening and cleaning sub-district.This duty ends at two kinds of situations, and the one, valve-off 32, two, the water level of recoil water tank are lower than the waterline 35 of hydraulic pressure microswitch 27 controls (schematically dummy line).

3: the filtration and the Hui Chi of recoil water

When the water arrival top of 26 li of recoil water tanks, and there have new recoil water to mend again to be fashionable, after the filtrate 34 that recoil water will be floated filters, overflowed by the case top, sends into pond 2 from the beginning, sub-district through aqueduct 33, and this process stops at the destruction of above-mentioned condition automatically.
