As shown in Figure 1-2, a water-saving system for double-barreled pneumatic waste water reuse, the upper part of the washbasin 2 is provided with an overflow port 1 to discharge excess water and prevent floods. Wash basin 2 bottoms are connected with drainage pipe 4, and first filter screen 3 is installed between wash basin 2 and drain pipe 4, and the first filter screen is the sucker type slag filter screen, can do preliminary filtration to the waste water after washing. The drain pipe 4 communicates with one end of the water inlet pipe 7 through the first three-way joint 5, and the other end of the water inlet pipe 7 communicates with the lower part of the outer cylinder 19, and the end is bell-shaped. A second filter screen 23 is installed in the outer cylinder 19 for secondary filtering of the waste water. A mud discharge pipe 9 is installed at the bottom of the outer cylinder 19, and the mud discharge pipe 9 is connected back to the drain pipe 4 through the second three-way joint 11, and is used to discharge the sludge settled after the waste water is left to stand. An electromagnetically controlled mud discharge valve 10 is installed on the mud discharge pipe 9, which can be automatically opened once under electrical control at intervals of a set time, and automatically closed after the set time.

An inner cylinder 18 is coaxially set in the outer cylinder 19, a check valve 20 is provided at the water inlet 21 at the bottom of the inner cylinder 18, and a water outlet pipe 24 is connected to the bottom of the inner cylinder 18. A ball float valve 25 is installed at the end of the water pipe 24 . A pressure sensor 13, a pressure gauge 14, an electric pump 15 and an electromagnetically controlled exhaust valve 16 are installed on the top of the inner cylinder 18. The electric pump here is preferably a miniature electric pneumatic pump. An exhaust pipe 12 is provided on the upper portion of the outer cylinder 19 , and a liquid level sensor 22 is installed on the lower portion of the inner cylinder 18 .

The working process of the present invention is described in further detail below:

Firstly, the maximum water level value and the minimum water level value are set for the liquid level sensor 22, and when these two values are reached, the liquid level sensor sends different signals to the controller. Then close the drain valve 6, after the waste water in the wash basin 2 is initially filtered by the first filter screen 3, the large suspended matter is filtered out, and the filtered waste water flows by itself through the drain pipe 4, the first three-way joint 5 and the water inlet pipe 7 Enter the bottom of the outer cylinder 19 to carry out sedimentation and separation of muddy water. At this time, the water level in the outer cylinder continues to rise, and the small molecular suspended matter is intercepted after passing through the detachable second filter screen 23. When the water level rises above the bottom of the inner cylinder 18, if the inner cylinder 18 is at standard atmospheric pressure, the one-way valve 20 at the bottom of the inner cylinder 18 will be opened under the action of water pressure, and the treated waste water will pass through the inner cylinder 18 from the outer cylinder 19 The water inlet 21 enters the inner cylinder, and finally the water levels of the inner and outer cylinders remain at the same height. When the water level in the inner cylinder rises to the highest water level _h1 , the liquid level sensor 22 acts to send a high water level signal to the controller 17, and the controller 17 controls the electric pump 15 to start automatically, and inflates and pressurizes the inner cylinder 18 to a set value. At this time, the pressure sensor 13 acts to send a pressure signal to the controller 17, and the controller 17 controls the electric pump 15 to stop pressurizing.

After flushing the toilet, the water level of the toilet water storage tank 26 drops, the float valve 25 opens, and the filtered water in the inner cylinder 18 is sent to the outlet pipe 24 under the action of the initial pressure _p1 of the compressed air to supplement the toilet water storage tank 26 of water. As the amount of water in the inner cylinder 18 decreases, the volume of the compressed air expands, the pressure of the inner cylinder decreases, and when the water level drops to the minimum water level _h2 , the liquid level sensor 22 acts to send a low water level signal to the controller 17, and the controller 17 controls the electromagnetic discharge The air valve 16 is opened to supplement the inner cylinder with atmospheric pressure from the outside, and the water in the outer cylinder enters the inner cylinder under the effect of atmospheric pressure to replenish the water level, and the water levels of the inner and outer cylinders remain at the same height again. When the water level in the inner cylinder rose to the maximum water level _h1 , the liquid level sensor 22 acted again, and sent a high water level signal to the controller 17, and the controller 17 controlled the electromagnetic exhaust valve 16 to close, and the electric pump 15 started automatically again.

If the amount of waste water used for reuse cannot meet the toilet flushing requirements, the tap water inlet valve is opened to supplement the toilet flushing water. If the waste water level exceeds the overflow port 1 in the washbasin 2, click the electromagnetic valve button of the controller 17 to open the electromagnetically controlled sludge valve 10 to drain water. At the same time, the controller 17 is set to control the opening of the mud discharge valve 10 every 12 hours to discharge mud and water, and it will automatically close after 2 minutes.
