Detailed implementation manners

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] It should be noted that the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means two or more, unless otherwise specifically defined.

[0024] As Figure 1-6 shown, the present application provides a wastewater treatment device for a wind farm, which is provided with a first treatment tank 1 and a second treatment tank 2. The first treatment tank 1 and the second treatment tank 2 are connected by a connecting cylinder 3. A first filtering component is arranged in the first treatment tank 1. The first filtering component includes a telescopic motor 4. The output end of the telescopic motor 4 is connected with a baffle 5. The baffle 5 is slidably matched with the first treatment tank 1. A water inlet 6 is arranged on the baffle 5. A filter screen 7 is connected at the water inlet 6. A second filtering component is arranged in the second treatment tank 2. The second filtering component includes a filtering cylinder 8. The position of the filtering cylinder 8 corresponds to the position of the connecting cylinder 3. A stirring component is arranged in the filtering cylinder 8. The stirring component includes a stirring motor 9. The output end of the stirring motor 9 is connected with a stirring shaft 10. Stirring rods 11 are connected to the stirring shaft 10. The outer sides of the stirring rods 11 are in contact with the inner wall of the filtering cylinder 8.

[0025] In the technical solution adopted in this embodiment, a first treatment tank 1 and a second treatment tank 2 are provided to treat wastewater. A connecting cylinder 3 is provided to allow the wastewater to flow from the first treatment tank 1 into the second treatment tank 2. A first filtering component is provided to filter larger particulate matters in the wastewater. Specifically, a first telescopic motor 4 can drive a baffle 5 to move up and down. When treating the wastewater, the telescopic motor 4 drives the baffle 5 to move downward, so that the water inlet 6 completely enters the first treatment tank 1. At this time, the filter screen 7 on the water inlet 6 can filter the large particulate matters in the wastewater. After the filter screen 7 works for a period of time, the telescopic motor 4 can drive the baffle 5 to move upward, so that the water inlet 6 and the filter screen 7 move upward out of the first treatment tank 1, thus facilitating the cleaning and replacement of the filter screen 7. A second filtering component is provided to further filter the particulate matters in the wastewater. Specifically, the further filtration of the particulate matters in the wastewater can be achieved through a filter cylinder 8. A stirring component is provided to stir the wastewater entering the second treatment tank 2. At the same time, the outer side of the stirring rod 11 contacts the inner wall of the filter cylinder 8, which can also prevent the particulate matters from blocking the filter cylinder 8, further ensuring the filtration effect of the particulate matters in the wastewater.

[0026] Furthermore, in this embodiment, a water inlet pipe 12 is also connected to the first treatment tank 1. The diameter of the water inlet pipe 12 is the same as that of the water inlet 6, and a control valve is connected to the water inlet pipe 12.

[0027] In the technical solution adopted in this embodiment, the setting of the water inlet pipe 12 allows the wastewater to enter the first treatment tank 1. The diameter of the water inlet pipe 12 is the same as that of the water inlet 6, which can align the water inlet 6 with the water inlet pipe 12, facilitating the wastewater to pass through the water inlet 6 from the water inlet pipe 12, thereby improving the utilization rate of the filter screen 7 on the water inlet 6 and further ensuring the filtration efficiency of the wastewater.

[0028] Furthermore, in this embodiment, a first chemical inlet pipe 13 and a second chemical inlet pipe 14 are also connected to the second treatment tank 2, and control valves are connected to both the first chemical inlet pipe 13 and the second chemical inlet pipe 14.

[0029] Furthermore, in this embodiment, the control valve includes a knob 15. The knob 15 is connected to a rotating shaft 16. The rotating shaft 16 is rotationally matched with the water inlet pipe 12, the first chemical inlet pipe 13, and the second chemical inlet pipe 14. A valve plate 17 is connected to the rotating shaft 16, and the diameter of the valve plate 17 is the same as that of the water inlet pipe 12, the first chemical inlet pipe 13, and the second chemical inlet pipe 14.

[0030] In the technical solution adopted in this embodiment, a control valve is provided to control the opening and closing of the first medicine inlet pipe 13, the second medicine inlet pipe 14, and the water inlet pipe 12, so as to control the start and stop of the water inlet and medicine adding operations. Specifically, by rotating the knob 15, the rotating shaft 16 can be rotated, thereby rotating the angle of the valve plate 17. When the angle of the valve plate 17 is perpendicular to the axial directions of the first medicine inlet pipe 13, the second medicine inlet pipe 14, and the water inlet pipe 12, it is in the closed state, and rotating it by another ninety degrees can completely open the control valve.

[0031] Furthermore, in this embodiment, a flow rate sensor is connected inside the connecting cylinder 3, and a pressure sensor is provided inside the valve plate 17.

[0032] In the technical solution adopted in this embodiment, setting the flow rate sensor can detect the flow rate of the wastewater. When the flow rate of the wastewater flowing through the connecting cylinder 3 fluctuates greatly, it is reasonable to judge that the filter screen 7 is blocked. At this time, the telescopic motor 4 can be driven to drive the baffle 5 to move upward to check the state of the filter screen 7. It should be noted that a liquid level sensor is also provided inside the second treatment tank 2, and the liquid level sensor can detect the liquid level inside the second treatment tank 2, so as to calculate the amount of wastewater inside the second treatment tank 2. By setting a pressure sensor on the valve plate 17, the quality of the medicine added to the first medicine inlet pipe 13 and the second medicine inlet pipe 14 can be measured, and the corresponding quality of the medicine can be added according to the amount of the incoming wastewater, thus ensuring the treatment quality of the wastewater.

[0033] Furthermore, in this embodiment, a water outlet pipe 18 is also connected to the bottom of the second treatment tank 2.

[0034] In the technical solution adopted in this embodiment, setting the water outlet pipe 18 facilitates the discharge of the treated wastewater from the second treatment tank 2, thereby facilitating the collection of the treated water.

[0035] The principle of the present utility model is as follows: The telescopic motor 4 drives the baffle 5 to move downward, aligning the water inlet 6 with the water inlet pipe 12. Subsequently, the control valve on the water inlet pipe 12 is opened, and the wastewater enters the first treatment tank 1 through the water inlet pipe 12. When the wastewater passes through the water inlet 6, the filter screen 7 can filter large particle impurities in the wastewater. Then, the wastewater enters the second treatment tank 2 through the connecting cylinder 3. The wastewater entering the second treatment tank 2 passes through the filter cylinder 8 and falls to the bottom of the second treatment tank 2. The filter cylinder 8 can further filter the particle impurities in the wastewater. Subsequently, according to the amount of wastewater entering the second treatment tank 2, two kinds of medicines with corresponding masses are added. The pressure sensor in the valve plate 17 can weigh the mass ratio of the two kinds of medicines, thereby ensuring the treatment quality of the wastewater. The treated wastewater is discharged from the second treatment tank 2 through the water outlet pipe 18, completing the treatment work of the wastewater. When the filter cylinder 8 filters the wastewater, the stirring motor 9 drives the stirring shaft 10 to rotate, thereby driving the stirring rod 11 to rotate. The stirring rod 11 cleans the inner wall of the filter cylinder 8 to prevent particulate matter from blocking the filter cylinder 8, thereby ensuring the treatment quality of the wastewater. After the treatment is completed, the telescopic motor 4 drives the baffle 5 to move upward, moving the water inlet 6 and the filter screen 7 out of the first treatment tank 1, facilitating the staff to clean and replace the filter screen 7.

[0036] By setting the first filtration component and the second filtration component, the present utility model performs secondary filtration on the particulate impurities in the wastewater, ensuring the removal quality of the particulate matter in the wastewater; by setting the liquid level sensor, the amount of wastewater in the second treatment tank 2 can be calculated. By setting the pressure sensor in the valve plate 17, two kinds of medicines with corresponding masses can be added according to the amount of wastewater, ensuring the treatment quality of the wastewater; by setting the telescopic motor 4 to drive the baffle 5 to move up and down, it is convenient to clean and replace the filter screen 7.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present utility model. In addition, in the description of the present utility model, the meaning of "a plurality of" is two or more, unless otherwise specifically defined.

[0038] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present application, and should all be included within the protection scope of the present application.
