It is connected by dredge pump 31 with waste 32 outside vacuum dirt box 33, the waste 32 and septic tank or suction-type sewer scavenger phase
Connection starts dredge pump 31 for dirt and is discharged into septic tank or soil pick-up when the liquid level of dirt in cabinet reaches extreme higher position
Vehicle closes dredge pump 31 when the liquid level of dirt in cabinet minimizes position, and blowdown operation stops, when dirty in cabinet
When the liquid level of object reaches superelevation position, alarm signal is issued, and stop using vacuum closet 2, forbidden to vacuum dirt box
Blowdown in 33.
The vacuum dirt box 33 is equipped with rinse mouth 28, reserved opening 29 and manual blowdown mouth 30, and the rinse mouth 28 is used
When later maintenance, dirt in flushing cisterns body, the reserved opening 29 is used to carry out vacuum dirt box 33 use when booster action,
The manual blowdown mouth 30 is for dirt to be discharged manually when failure or maintenance.
The filtered water tank 7 is equipped with venthole 8, water inlet valve group 10, high liquid level meter 9, low liquid level meter 11, discharge outlet and overflow
Mouthful, the venthole 8 is used for balance box inner and outer air pressure, and the water inlet valve group 10 is connect with external water source, for controlling clear water
7 moisturizing of case, the high liquid level meter 9 and low liquid level meter 11 are for liquid level in detection box, when the low liquid level meter 11 issues
When signal, water inlet valve group 10 is opened to the inside of filtered water tank 7 plus water, and when the high liquid level meter 9 issues signal, water inlet valve group 10 is closed
It closes, stops adding water to the inside of filtered water tank 7；The discharge outlet is equipped with Manual draining valve 12, when being used for Maintenance and Repair, blow-down tank
Body；The position of the overflow port is higher than high liquid level meter 9, and water extra in filtered water tank 7 is discharged into septic tank by the overflow port.
The filtered water tank 7 passes through the bath solenoid valve 4 and urinal of feed pump 6 and water filter 5 and vacuum closet
Solenoid valve 3 of washing by water is connected.
The buck tank inlet 18 is connected with hand basin drain outlet, and grey water treating module 19 is equipped in the gray water tank 17
With low liquid level meter 15, the ash water treating module 19 is used to be filtered processing to hand basin draining, and the low liquid level meter 15 is used
It is detected in 17 water level of gray water tank；When low liquid level meter 15 generates signal, the 17 less deficiency of inside water of gray water tank is indicated
To be rinsed to closet, moisturizing need to be rinsed using filtered water tank 7.
The gray water tank 17 is equipped with venthole 13, overflow hole 14 and discharge outlet, and the venthole 13 is for balancing buck
17 inner and outer air pressure of case, the overflow hole 14 are used to for extra water being discharged into septic tank, and the discharge outlet is equipped with Manual draining valve 16,
Buck in cabinet is emptied when for Breakdown Maintenance.
The gray water tank 17 passes through the bath solenoid valve of grey water solenoid valve 20, feed pump 6 and water filter 5 and vacuum closet
4 and urinal bath solenoid valve 3 be connected.
It is preferential to use the waste water being recycled in gray water tank 17, when recycling waste water deficiency, filtered water tank 7 when toilet flushing
It is fed.
As shown in Fig. 2, it is described ash water treating module 19 use multistage filtering processing mode, including internal filtration layer 1901, in
Between filter layer 1902 and outer filter layer 1903, the cavity that wherein internal filtration layer 1901 and intermediate filter layer 1902 are formed be it is upper it is narrow under
Wide structure, tilt angle are 30 °~70 °, and 1901 filter mesh mesh number of internal filtration layer is 100~300 mesh；Intermediate filter layer 1902
Filter mesh mesh number is 200~400 mesh；Outer 1903 filter mesh mesh number of filter layer is 300~600 mesh；Outer 1903 He of filter layer
In the cavity that intermediate filter layer 1902 is formed, absorption activated carbon is placed；Internal layer filtering adds adsorption activity using husky filter, middle layer
Charcoal carries out carbon filter, and outer layer three-stage filtration uses hyperfiltration treatment mode, and it is more preferable convenient that this structure has, buck impurity content after filtering
Few effect.
System is before use, external water source is connected with the valve group 10 on filtered water tank 7；And the hand basin in lavatory is generated
Buck access gray water tank 17 in.
The use process of public lavatory of the invention is：
System prepares：
1) vacuum pressure value in vacuum dirt box 33 is detected；
2) the use pressure of vacuum dirt box 33 is controlled between P1-P2 by vacuum pump 26 and vacuum meter 25；
3) liquid level of filtered water tank 7 and the liquid level of gray water tank 17 are detected；
Use vacuum closet 2：
1) push button is pressed；
2) bedpan dirt is rinsed by the water that water pump 6 aspirates filtered water tank 7 or gray water tank 17；
3) after time T1, dirt bleed valve is opened, bedpan is connected to vacuum dirt box 33, dirt is discharged into vacuum dirt
Case 33；
4) after time T2, dirt bleed valve is closed, by the connection closed of bedpan and vacuum dirt box 33；
Use urinal 1：
1) after using urinal 1, urine is automatically flowed into intermediate box 24；
2) bedpan dirt is rinsed by the water that water pump 6 aspirates filtered water tank 7 or gray water tank 17；
3) intermediate box 24 carries out level sensing, after dirt reaches certain liquid level in cabinet, opens bleed valve, dirt is arranged
Enter vacuum dirt box 33；
4) after certain time interval T 3, bleed valve is closed；
Auxiliary movement：
When 33 liquid level of vacuum dirt box reaches high liquid level, dredge pump 31 is acted, and vacuum dirt box 33 is emptied；
When 33 liquid level of vacuum dirt box reaches superelevation liquid level, display alarm；
When 7 liquid level of filtered water tank is too low, external source is opened, carries out moisturizing；
When filtered water tank 7 and excessively high 17 liquid level of gray water tank, water, which overflows, flows into septic tank.
The working principle of the invention is：In use, aspirating the air of vacuum dirt box 33 by vacuum pump 26 first, make case
Internal portion generates certain negative pressure；When using vacuum closet 2, push button is pressed, control module controls bath solenoid valve 4,
Rinse dirt, after certain time interval T 1, vacuum drain valve is opened, by bedpan dirt and flushing water be drawn into together by negative pressure
In vacuum dirt box 33, vacuum drain valve is closed after certain time interval T 2；When using urinal 1, the sewage in urinal 1 passes through
Gravity is flowed into intermediate box 24, when reaching certain liquid level in intermediate box 24, bleed valve is opened, by the sewage one in intermediate box
It rises and is drawn into vacuum dirt box 33 by negative pressure；Public lavatory is furnished with filtered water tank 7 and gray water tank 17, passes through water pump 6, solenoid valve
It is connected with pipeline with the clear water water supply pipe of vacuum closet 2 and urinal 1；Filtered water tank 7 for store flushing clear water or from
Water, gray water tank 17 are used to store the washes of hand basin, and to recycling and reusing after waste water progress three-stage filtration processing, greatly
It is big to reduce water consumption, effectively save water resource.
