Detailed ways

The present invention will be further described in detail below with reference to the accompanying drawings.

As shown in Figures 1 and 2, a device for cleaning and utilizing sewage in a built environment includes a cylindrical filter frame 1 for treating sewage. The bottom of the filter frame 1 is provided with an outlet pipe 2 for discharging treated sewage. A screw rod 3 is fixedly connected to the middle part of the filter frame 1. Around the screw 3, the filter frame 1 is connected with a micro filter 4, a disinfection filter 5 and an activated carbon filter 6 from bottom to top. Among them, disinfectant is installed between the disinfection filter 5 and the activated carbon filter 6, and activated carbon is installed on the activated carbon filter 6.

The screw rod 3 is provided with a transmission seat 7 . A plurality of balls 8 are arranged between the transmission seat 7 and the screw 3 . The balls 8 roll between the pitches of the screw 3 . A ball screw pair is formed between the transmission seat 7, the screw 3 and the balls 8. When the screw rod 3 is fixed, the transmission seat 7 rotates correspondingly to the screw rod 3. A piston rod 9 is fixedly connected to one side of the transmission seat 7 . The other end of the piston rod 9 is bearing-connected with a pressure plate 10 . A water injection tank 11 is provided outside the pressure plate 10 in close cooperation with the pressure plate 10 . A sealed environment is formed between the water injection tank 11 and the pressure plate 10, that is, in the form of a hydraulic cylinder.

Correspondingly, transmission plates 12 are provided on both sides of the transmission seat 7 . A water inlet channel 13 is provided in the transmission plate 12 . The water inlet channel 13 is connected with the water outlet channel 14 and the hydraulic channel 15 . The transmission plate 12 has a push plate 16 hingedly connected to one side of the water outlet channel 14 . A torsion spring (not shown in the figure) is provided between the push plate 16 and the transmission plate 12 . A sliding seat 17 is provided in the hydraulic channel 15 . A stirring rod 18 is connected to one side of the sliding seat 17 . The sliding seat 17 and the transmission plate 12 are internally connected with a spring 19.

In addition, when designing this device, it is necessary to make the water pressure F=ρghs greater than the elastic force F=Kx of the spring 19 when the water filling tank 11 is filled with water. Among them, x is the maximum displacement of spring 19, and s is the area of the sliding seat.

There are at least two related structures of the above-mentioned transmission plate 12, which are respectively provided on both sides of the transmission seat 7.

Correspondingly, a connecting water pipe 20 is connected between the water inlet channel 13 and the water injection tank 11. The connecting water pipe 20 allows the water in the water injection tank 11 to enter the water inlet channel 13 along the connecting water pipe 20. At the same time, a liquid level difference is formed. Thereby the pressure of water in the water inlet channel 13 is increased.

The water injection tank 11 is in contact with a floating block 21 at a position connected to the water pipe 20 . The floating block 21 is hollow in the middle and the outer periphery is in contact with the water injection tank 11 . In the state of not being filled with water, the floating block 21 seals the connecting water pipe 20 so that sewage does not enter the water inlet channel 13 through the connecting water pipe 20 .

Optimally, a spring 22 is provided between the water filling tank 11 and the pressure plate 10 . A drain valve 23 is provided on one side of the water injection tank 11. When the drain valve 23 is opened, the sewage in the water injection tank 11 can be discharged.

Optimized, always-open drain outlets 24 are provided on both sides of the water injection tank 11 .

In addition, a water inlet pipe 25 is connected to the top of the water injection tank 11, and a water pump 26 is connected to the water inlet pipe 25. When the water pump 26 works, the sewage enters the water injection tank 11 through the water inlet pipe 25.

When the pressure plate 10 moves to connect the drain port 24 with the inside of the water filling tank 11 , excess water will flow out of the water filling tank 11 . At this time, the water outflow speed in the water injection tank 11 is greater than the speed into the water injection tank 11, so that the second spring 22 drives the pressure plate 10 to rebound. The pressure plate 10 rebounds upward instantaneously, closing the drain outlet 24 and driving the transmission seat 7 to rotate. The rotation of the transmission seat 7 drives the transmission plate 12 to rotate, so that the protruding stirring rod 18 rotates to stir the activated carbon, and at the same time, the water outlet channel 14 rotates to discharge water. While stirring, the water is rotated and sprayed under the action of centrifugal force, which increases the contact area between water and activated carbon and improves the sewage treatment effect. At the same time, the reason for stirring the activated carbon is that there may be strongly adhesive substances in the sewage. In order to prevent the activated carbon from adhering, the activated carbon is stirred. In addition, stirring can also change the distribution position of activated carbon, causing each activated carbon to shift, so that each activated carbon can participate in the adsorption treatment of sewage and improve the utilization efficiency of activated carbon. The above process can achieve efficient treatment of sewage only by injecting sewage. At the same time, it does not require the participation of other electric driving devices, which improves the treatment effect and achieves energy saving.

Overall working process:

1. The initial state is as shown in Figure 1. In this state, the water pump 26 has not yet worked and no sewage is injected into the water injection tank 11;

2. The water pump 26 works and injects sewage into the water injection tank 11 along the water inlet pipe 25. At the beginning, the liquid level in the water injection tank 11 gradually rises. At this time, the pressure plate 10 moves downward, the water injection tank 11 is not yet filled with sewage, and the floating block 21 still closes the connecting water pipe 20. When the pressure plate 10 moves downward, it drives the transmission seat 7 to rotate, thereby driving the transmission disk 12 to rotate. Since water has not yet entered the connecting water pipe 20 at this time, the stirring rod 18 is inside the transmission disk 12, and the transmission disk 12 gradually rotates and moves downwards, but No water is discharged, and the push plate 16 is in a closed state.

3. When the liquid level in the water injection tank 11 is higher than the floating block 21, the floating block 21 moves upward to no longer close the connecting water pipe 20, and the sewage enters the water inlet channel 13 of the transmission plate 12 along the connecting water pipe 20, and finally enters to the water outlet channel 14 and the hydraulic channel 15. The stirring rod 18 in the hydraulic channel 15 is pushed outward under the action of hydraulic pressure. During the pushing process, the push plate 16 is driven to rotate, and its state is as shown in Figure 2 (the intermittent short horizontal lines in the figure represent sewage fluid). In the state of Figure 2, the rotating disk has rotated 180 degrees. At this time, the two connected water pipes 20 intersect, and this position is the extreme position. The stirring rod 18 passes through the hydraulic channel 15 and is inserted into the activated carbon;

4. Continue to inject water until the liquid level in the water injection tank 11 reaches the top of the water injection tank 11. At this time, the water injection tank 11 is filled with sewage. At this position, the water outlet is connected to the water injection tank 11, and part of the sewage overflows from the water outlet. At this time, the second spring 22 drives the pressure plate 10 to rebound. The pressure plate 10 rebounds upward instantaneously, closing the drain outlet 24 and driving the transmission seat 7 to rotate. The rotation of the transmission seat 7 drives the transmission plate 12 to rotate, so that the protruding stirring rod 18 rotates to stir the activated carbon, and at the same time, the water outlet channel 14 rotates to discharge water. While stirring, the water is rotated and sprayed under the action of centrifugal force, which increases the contact area between water and activated carbon and improves the sewage treatment effect. After that, the pressure plate 10 moves upward so that the water outlet is no longer connected to the water injection tank 11, the water pump 26 continues to inject water, the transmission plate 12 moves downward and rotates in the opposite direction, stirs the activated carbon and sprays sewage. Repeat the above steps until the sewage is fully adsorbed and treated;

5. The sewage after activated carbon treatment enters the disinfection filter 5 through the activated carbon filter 6 to disinfect the sewage. Finally, it is finally filtered through the micro filter 4 before the treated sewage can be discharged through the outlet pipe 2, so that the sewage Can be reused.

Beneficial effects:

1. The present invention makes full use of the hydraulic pressure of the sewage during sewage treatment to rotate and move the transmission seat 7, and at the same time drives the stirring rod 18 to penetrate the activated carbon and stir the activated carbon. The whole process can achieve the stirring of the activated carbon and the sewage without the need for additional electric driving devices. The rotating spraying effect of centrifugal force increases the contact area between sewage and activated carbon. Compared with activated carbon in a static state, although this treatment method prolongs the processing speed of sewage, it achieves very good results in terms of energy conservation and environmental protection. The activated carbon in the filter rack 1 changes its distribution position, so that each activated carbon can participate in the sewage treatment process, improving the utilization rate of the activated carbon and improving the sewage treatment effect.

2. After setting the water outlet, the pressure plate 10 can move up and down, thereby causing the stirring rod 18 to rotate back and forth, fully stirring the activated carbon and causing the sewage water to be sprayed in a rotating manner. In addition, the sewage flowing out from the water outlet can also fall on the transmission plate 12 and fall into the activated carbon for treatment under the action of centrifugal force, further improving the sewage treatment speed;

3. The floating block 21 is used to seal the connecting water pipe 20, so that the stirring rod 18 is inside the transmission plate 12 when the transmission plate 12 initially moves down, thereby reducing the resistance of the transmission plate 12 entering the activated carbon.

Those skilled in the art can make modifications to this embodiment without creative contribution as needed after reading this specification. However, as long as the rights of the present invention are All requirements are protected by patent law.
