Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, a device for cleaning and utilizing sewage in a building environment comprises a cylindrical filter rack 1 for treating sewage. The bottom of the filter frame 1 is provided with a water outlet pipe 2 for discharging the treated sewage. The middle part of the filter frame 1 is fixedly connected with a screw rod 3. Around the screw rod 3, the filter frame 1 is connected with a micro filter screen 4, a disinfection filter screen 5 and an active carbon filter screen 6 from bottom to top. Wherein, a disinfectant is arranged between the disinfection filter screen 5 and the active carbon filter screen 6, and the active carbon is arranged on the active carbon filter screen 6.
The screw rod 3 is provided with a transmission seat 7 in a matching way. A plurality of balls 8 are arranged between the transmission seat 7 and the screw rod 3 in a matching way. The balls 8 roll between the pitch of the screw 3. A ball screw pair is formed among the transmission seat 7, the screw rod 3 and the ball 8. The screw 3 is fixed, and the transmission seat 7 rotates corresponding to the screw 3. One side of the transmission seat 7 is fixedly connected with a piston rod 9. The other end of the piston rod 9 is connected with a pressure plate 10 through a bearing. A water injection tank 11 is arranged outside the pressure plate 10 in a close fit manner. A sealed environment, i.e. in the form of a hydraulic cylinder, is formed between the water injection tank 11 and the pressure plate 10.
Correspondingly, the two sides of the transmission seat 7 are provided with transmission discs 12. A water inlet channel 13 is arranged in the transmission disc 12. The water inlet channel 13 is communicated with a water outlet channel 14 and a hydraulic channel 15. A push plate 16 is hinged on one side of the water outlet channel 14 of the transmission disc 12. A torsion spring (not shown) is provided between the push plate 16 and the transmission disc 12. A sliding seat 17 is arranged in the hydraulic passage 15. One side of the sliding seat 17 is connected with a stirring rod 18. The sliding seat 17 and the transmission disc 12 are internally connected with a first spring 19.
In addition, in designing the present device, it is necessary to make the pressure F ρ ghs of water larger than the spring force F Kx of the first spring 19 in a state where the water tank 11 is filled with water. Wherein x is the maximum displacement of the first spring 19, and s is the area of the sliding seat.
The related structures of the transmission disc 12 are at least two and are respectively arranged at two sides of the transmission seat 7.
Correspondingly, a communication water pipe 20 is connected between the water inlet channel 13 and the water injection tank 11, and the communication water pipe 20 enables water in the water injection tank 11 to enter the water inlet channel 13 along the communication water pipe 20, and simultaneously, a liquid level difference is formed, so that the pressure of the water in the water inlet channel 13 is improved.
The water injection tank 11 has the floating block 21 in the position department butt of intercommunication water pipe 20, and the floating block 21 middle part is hollow, and the periphery and water injection tank 11 butt. In the non-water-injected state, the floating block 21 closes the communication water pipe 20 so that the sewage does not enter the water inlet passage 13 through the communication water pipe 20.
Preferably, a second spring 22 is arranged between the water injection tank 11 and the pressure plate 10. A drain valve 23 is provided at one side of the water injection tank 11, and when the drain valve 23 is opened, the sewage in the water injection tank 11 can be discharged.
Preferably, the water injection tank 11 is provided with water outlets 24 on both sides thereof, which are always open.
In addition, the top of the water injection tank 11 is connected with a water inlet pipe 25, and the water inlet pipe 25 is connected with a water pump 26. The water pump 26 is operated to allow sewage to be introduced into the water injection tank 11 through the water inlet pipe 25.
When the pressing plate 10 is moved to communicate the drain port 24 with the inside of the water filling tank 11, the surplus water flows out of the water filling tank 11. At this time, the water in the water injection tank 11 flows out at a speed higher than that of the water flowing into the water injection tank 11, so that the second spring 22 drives the pressing plate 10 to rebound. Pressing plate 10 is instantaneous upwards kick-backs, drives the rotation of driving seat 7 when closing outlet 24, and driving seat 7 rotates and drives driving disc 12 and rotate to make the puddler 18 of wearing out rotate and stir the active carbon, go out the rotatory water of water passageway 14 simultaneously, make water rotatory under the effect of centrifugal force spray when stirring, improve the area of contact of water and active carbon, improve the treatment effect of sewage. Meanwhile, the reason for stirring the activated carbon is that highly adhesive substances may exist in the sewage, and the activated carbon is stirred in order to prevent the activated carbon from adhering. In addition, the distribution position of the activated carbon can be changed by stirring, so that each activated carbon can move, each activated carbon can participate in the adsorption treatment of sewage, and the utilization efficiency of the activated carbon is improved. The process can realize the efficient treatment of the sewage only through the link of injecting the sewage, and meanwhile, the participation of other electric driving devices is not needed, so that the treatment effect is improved, and the purpose of saving energy is achieved.
The whole working process is as follows:
1. the initial state is shown in fig. 1, in which the water pump 26 is not operated and no sewage is injected into the water injection tank 11;
2. the water pump 26 is operated to inject the sewage into the water injection tank 11 through the water inlet pipe 25. At the beginning, the liquid level in the water injection tank 11 gradually rises, at this time, the pressing plate 10 moves downwards, the water injection tank 11 is not filled with sewage, and the floating block 21 still seals the communication water pipe 20. The pressing plate 10 drives the transmission seat 7 to rotate when moving downwards, so as to drive the transmission disc 12 to rotate, and because water is not fed into the communication water pipe 20 at the moment, the stirring rod 18 is positioned inside the transmission disc 12, the transmission disc 12 gradually rotates downwards and moves, but water is not discharged, and the pushing 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 upwards to no longer seal the communication water pipe 20, and the sewage enters the water inlet channel 13 of the transmission disc 12 along the communication water pipe 20 and finally enters the water outlet channel 14 and the hydraulic channel 15. The stirring rod 18 in the hydraulic channel 15 is pushed outwards under the action of hydraulic pressure, and the pushing plate 16 is driven to rotate in the pushing process, and the state of the stirring rod is shown in figure 2 (the discontinuous short transverse line in the figure is shown by sewage fluid). In the state of fig. 2, the rotary disk is rotated by 180 degrees, and at this time, the two communication water tubes 20 are crossed, which is a limit position. The stirring rod 18 penetrates out of the hydraulic channel 15 and is inserted into the activated carbon;
4. the water injection is continued so that the liquid level in the water injection tank 11 reaches the top of the water injection tank 11, and at this time, the water injection tank 11 is filled with the sewage, and at this position, the water outlet is communicated with the water injection tank 11, and a part of the sewage overflows therefrom. At this time, the second spring 22 drives the pressing plate 10 to rebound. Pressing plate 10 is instantaneous upwards kick-backs, drives the rotation of driving seat 7 when closing outlet 24, and driving seat 7 rotates and drives driving disc 12 and rotate to make the puddler 18 of wearing out rotate and stir the active carbon, go out the rotatory water of water passageway 14 simultaneously, make water rotatory under the effect of centrifugal force spray when stirring, improve the area of contact of water and active carbon, improve the treatment effect of sewage. Then, the pressing plate 10 moves upwards to ensure that the water outlet is not communicated with the water injection tank 11 any more, the water pump 26 continues injecting water, the transmission disc 12 moves downwards in the reverse direction to rotate, and the activated carbon is stirred and sewage is sprayed. Repeating the steps to ensure that the sewage is fully adsorbed and treated;
5. the sewage after the active carbon treatment enters the disinfection filter screen 5 through the active carbon filter screen 6, thereby disinfecting the sewage, finally filtering the sewage which is discharged through the water outlet pipe 2 at the rear part through the micro filter screen 4, and recycling the sewage.
Has the beneficial effects that:
1. according to the invention, the transmission seat 7 is rotated and moved by utilizing the hydraulic pressure of sewage during sewage treatment, and the stirring rod 18 is driven to penetrate through the transmission seat to stir the activated carbon, so that the stirring effect on the activated carbon and the rotating spraying effect of the sewage centrifugal force can be realized without an additional electric driving device in the whole process, the contact area of the sewage and the activated carbon is increased, compared with the activated carbon in a static state, the treatment mode prolongs the sewage treatment speed, but achieves a very good effect on the aspect of energy conservation and environmental protection, the distribution positions of the activated carbon in the filter frame 1 are changed, so that all the activated carbons can participate in the sewage treatment process, the utilization rate of the activated carbon is increased, and the sewage treatment effect is improved.
2. After the water outlet is arranged, the pressing plate 10 can move up and down, so that the stirring rod 18 rotates back and forth, and sewage is discharged in a rotating spraying mode while the activated carbon is fully stirred. In addition, the sewage flowing out of the water outlet can also fall onto the transmission disc 12 and fall into the activated carbon under the action of centrifugal force for treatment, so that the sewage treatment speed is further improved;
3. the floating block 21 is adopted to seal the water pipe 20, so that the stirring rod 18 is positioned inside the transmission disc 12 when the transmission disc 12 initially moves downwards, and the resistance of the transmission disc 12 entering the activated carbon is reduced.
