The specific embodiment
Below in conjunction with embodiment and accompanying drawing secondary waste water utilizing pressurization system of the present invention and control method are made detailed description.
Secondary waste water utilizing pressurization system of the present invention and control method are utilized the bigger pressure of tap water itself, make the waste water supercharging to be transported to the higher position or to be input to the pressurize water tank, to reach the purpose that second use waste water is flushed the toilet.
As shown in Figure 1; Secondary waste water utilizing pressurization system of the present invention; Comprise: lavatory water-storing tank 13 and lavatory basin 1, described lavatory basin 1 is connected in series with waste water holder 4, big hydraulic cylinder 6 and small cylinder 11 through water-filled pipe successively, and the bottom of said small cylinder 11 connects outside resource of water supply 14 through supply channel; Described big hydraulic cylinder 6 also is connected with lavatory water-storing tank 13 through water-filled pipe; The upper end of big hydraulic cylinder 6 is connected through water-filled pipe with the lower end that is arranged on small cylinder 11, and water-storing tank 13 bottoms, described lavatory also connect outside resource of water supply 14 through supply channel, wherein; Be provided with big piston 7 in the described big hydraulic cylinder 6; Be provided with valve piston 10 in the described small cylinder 11, described big piston 7 is connected through a piston rod 8 with valve piston 10, the valving that also is provided with control module 15 and the control supply channel that links to each other with control module 15 and water-filled pipe conducting or closes., control module 15 described here can adopt the sheet machine, or control chip.The delivery port of described lavatory basin 1 is provided with screen pack 2, the bottom of lavatory basin 1 be provided with solid-holding device 3.The upper end of described waste water holder 4 also is provided with overfall 16.
The principle of supercharging is exactly to utilize the big pressure of tap water own, promotes whole valve piston 10 and moves up.Because big valve piston fuses, big piston 7 one ends are synchronized with the movement.Through the switching campaign of valve, the pressure of big hydraulic cylinder is constantly increased.When pressure during greater than the pressure of overflow valve, waste water gets into the water storage device of usefulness of flushing the toilet, thereby has realized the second use after the supercharging of waste water.
In said process, the diameter proportion of big valve piston is a key factor of the efficient of influence secondary waste water utilizing pressurization system of the present invention.We establish the straight footpath of big piston is D1, and the valve piston diameter is D2, and the pressure of the input tap water of small cylinder is P2, and the pressure of big hydraulic cylinder increases gradually, increases to the setting pressure of overflow valve C, is made as P1.Because big piston and valve piston are linked to be an integral body, so because the difference of pressure causes forming pressure differential.If the power of valve piston is F2, the power of big piston is F1, satisfies relation:
F2=π×P2×D22/4>F1=π×P1×D12/4
So piston moves up, rise to P2 to the pressure of waste water.
By above analysis, can know: realize the raising of water reuse efficient, must increase the diameter proportion of big piston and valve piston, the valve piston diameter is as far as possible little, and the big piston diameter is big as far as possible.
The ratio of size piston diameter is by the setting pressure decision of water end (W.E.) pressure and overflow valve from the beginning;

As shown in Figure 2, the control method that is used for the secondary waste water utilizing pressurization system of the present invention comprises the steps:
Whether 1 control module is judged needs supplementing water in the water-storing tank of lavatory, be to get into next step, otherwise return wait state;
2 control modules judge whether big hydraulic cylinder 6 is full, are to get into next step, otherwise get into the 6th step;
3 control modules control is arranged on big hydraulic cylinder 6 and closes with normally open solenoid valve B on the water-filled pipe that small cylinder 11 is communicated with, and the unidirectional normally closed solenoid valve A that controls on the supply channel that is arranged on small cylinder 11 bottoms opens;
4 control modules judge whether waste water holder 4 is full, are to get into next step, otherwise continue to judge whether waste water holder 4 is full;
5 control modules control is arranged on big hydraulic cylinder 6 and opens with normally open solenoid valve B on the water-filled pipe that small cylinder 11 is communicated with, and the unidirectional normally closed solenoid valve A that controls on the supply channel that is arranged on small cylinder 11 bottoms closes, and returns wait state then;
The unidirectional normally closed solenoid valve E that 6 control modules are controlled on the supply channel that is arranged on lavatory water-storing tank 13 bottoms opens, and replenishes tap water to lavatory water-storing tank 13;
7 control modules judge whether water-storing tank 13 moisturizings in lavatory are full, are to close unidirectional normally closed solenoid valve E, return wait state then, otherwise continue to replenish tap water to lavatory water-storing tank 13.
The course of work of secondary waste water utilizing pressurization system of the present invention and control method is following:
The waste water that lavatory basin 1 produces filters through screen pack 2, gets into waste water holder 4.If waste water contains impurity, can be deposited in the solid-holding device 3, with the anti-clogging screen pack.And solid-holding device 3 can be cleared up easily.If waste water holder 4 is full, flow out through overfall 16.Then, often opening one-way valve C gets into big hydraulic cylinder 6.Under the action of gravity of waste water in the above of big hydraulic cylinder 6, be in extreme lower position.After big hydraulic cylinder 6 was full of, after obtaining lavatory water-storing tank 13 that first sensor 12 transmits simultaneously and needing the information of supplementing water, control module began a series of control action (control flow chart is seen in concrete action).Whether the effect of second sensor 5 provides big hydraulic cylinder has the information that enough can supply the waste water of supercharging.After obtaining first sensor 12 and needing the information of supply, judge that normally open solenoid valve B closes under the situation that second sensor 5 also allows, unidirectional normally closed solenoid valve A opens, and normal opening one-way valve C closes automatically.Because the pressure of tap water is very big, and big hydraulic cylinder 6 pressure are very little, and the force valve piston 10 and big piston 7 integral body of tap water move up.After the pressure of big hydraulic cylinder reached the setting pressure of overflow valve D, overflow valve was opened, and waste water gets into lavatory water-storing tank 13 and stores with certain pressure.If lavatory water-storing tank 13 is full of or big valve piston reaches capacity position is passed to control module by the first sensor and second sensor with information, thereby is closed unidirectional normally closed solenoid valve A, open normally open solenoid valve B, pressurization finishes.At this moment, overflow valve D closes, and the pressure of big or small two hydraulic cylinders reaches balance; Normal opening one-way valve C because upper pressure greater than following and open, waste water is because gravity promotes big piston and moves down, the water of small cylinder and waste water get into big hydraulic cylinder; Return to initial position, for next circulation is got ready.In addition, if lavatory water-storing tank 13 lack of water, and wastewater flow rate would be not enough, at this moment opens unidirectional normally closed solenoid valve E through control module, directly pours with tap water, guarantees to use normally.Also having a kind of situation is exactly that waste water holder and lavatory water-storing tank all are full of, and the waste water that exceeds capacity will be discharged automatically.
From above analysis, can find out that secondary waste water utilizing pressurization system of the present invention and control method have following characteristics: 1) its pressurization is simple, does not need other the energy, has solved the problem of waste water supercharging; 2) whole process can be carried out under the control of control system automatically; 3) have very strong compliance, make simply, when utilizing waste water, do not make troubles to our life.So this cover system tool has bigger promotional value in today of water resource growing tension.
