During wastewater sampling, it may be necessary to collect wastewater from different layers. However, the analysis of the chemical composition of wastewater requires discarding the influence of floating debris and other impurities. If continuous sampling is required, these impurities can also affect the sampling port. Therefore, it is necessary to design an automatic wastewater sampler that can handle this problem.

Detailed Implementation

[0024] Please see Figures 1-3 In this embodiment of the present invention, an automatic wastewater sampler based on phased array radar includes a water storage tank 1, a water pump 3, and a water receiving tank 4. The input end of the water pump 3 is connected to the water receiving tank 4 via a flexible hose, and the output end of the water pump 3 is connected to the water storage tank 1. A mesh cylinder 14 is fixedly connected to the bottom of the water storage tank 1, and a guide bucket 15 is fixedly connected to the upper part of the mesh cylinder 14. The output end of the water pump 3 is connected to the guide bucket 15 via a guide pipe 16. A rotating component 5 driven by water flow is rotatably connected to the guide bucket 15. A ventilated cylinder 2 for controlling the pressure inside the water storage tank 1 is assembled and connected to the water storage tank 1.

[0025] In this embodiment, based on phased array radar level gauge technology, the sewage level at different depths in the sewage tank can be accurately determined. Then, the water receiving tank 4 is suspended to the corresponding height in the sewage tank via a flexible hose connected to it for sewage collection. This allows for flexible control of the collection height as needed. Using a phased array radar level gauge facilitates monitoring at different depths in the sewage tank, and the sampling height can be designed according to requirements, making sampling more convenient and improving detection efficiency. In specific operation, after starting the water pump 3, the sewage can be drawn in through the water receiving tank 4 and injected into the water storage tank 1. After passing through the guide pipe 16, the sewage is discharged from the guide bucket 15. After passing through the rotating part 5, the sewage can drive the rotating part 5 to rotate on the screen cylinder 14. Then, the water flow in the water storage tank 1 can undergo centrifugal rotation. The sewage permeates into the screen cylinder 14 through the outside of the screen cylinder 14. After being filtered by the screen cylinder 14, it can be purified and discharged. When the sewage is injected into the water storage tank 1, the internal pressure of the water storage tank 1 can be controlled by the venting tube 2, so as to facilitate the adjustment of the filtration efficiency. At the same time, the centrifugal rotation of the sewage in the water storage tank 1 can also prevent impurities from adhering to the surface of the screen cylinder 14, so as to avoid affecting the efficiency of continuous sampling.

[0026] In this embodiment, both the mesh cylinder 14 and the water storage cylinder 1 are cylindrical structures. The edge of the guide bucket 15 and the upper edge of the mesh cylinder 14 are sealed and fitted together. The mesh cylinder 14 is a fine-mesh screen. The surface of the mesh cylinder 14 can be covered with filter cloth. Wastewater can permeate and be filtered through the mesh cylinder 14, and pressure can promote filtration.

[0027] In this embodiment, the lower surface of the water receiving tank 4 can be flat, so that the water receiving tank 4 can be easily placed at the bottom of the sewage tank and can be closely fitted for collection.

[0028] Please see Figures 1-3 In this embodiment of the utility model, the mesh cylinder 14 and the water storage cylinder 1 are arranged concentrically, the guide pipe 16 extends from the bottom of the water storage cylinder 1 and passes through the mesh cylinder 14 upwards, and its end passes through the center of the guide bucket 15.

[0029] In this embodiment, a base 11 is fixedly fitted at the bottom of the water storage cylinder 1. A guide pipe 16 extends through from one side of the base 11, bends, and then passes vertically upward through the mesh cylinder 14. A water outlet pipe 13 is connected to one side of the water storage cylinder 1. The water outlet pipe 13 and the mesh cylinder 14 are connected. After treatment, the sewage can be discharged through the water outlet pipe 13. A pipe for discharging solid dirt is also provided through one side of the water storage cylinder 1. The end of the pipe is connected between the inner wall of the water storage cylinder 1 and the outer wall of the mesh cylinder 14. A sealing cap is fitted at the opening of the water outlet pipe 13 and the pipe through a threaded connection.

[0030] In this embodiment, the water pump 3 transports the sewage collected in the water tank 4 through the guide pipe 16, and the guide bucket 15 can conveniently guide the sewage to the outside of the mesh cylinder 14. The guide bucket 15 can, as Figure 1-2As shown, the larger opening of the guide bucket 15 is set upward and fixed to the edge of the mesh cylinder 14. The smaller opening of the guide bucket 15 is connected to the guide pipe 16. Similarly, the larger opening of the guide bucket 15 can be set downward and the smaller opening is located on the upper side. In this way, the guide pipe 16 can more easily guide the sewage after it is injected.

[0031] Please see Figures 1-2 In this embodiment of the utility model, the upper end of the water storage cylinder 1 is equipped with an upper cover 12, and the upper cover 12 is rotatably connected with a vent cylinder 2. A flow limiting plate 17 is fixedly embedded in the upper cover 12 and is arranged opposite to and correspondingly adapted to the vent cylinder 2.

[0032] In this embodiment, when sewage is injected for filtration, the vent 2 is rotated to connect the inside of the water storage tank 1 with the outside. At this time, the pressure inside and outside the water storage tank 1 is balanced. Rotating the vent 2 controls the aperture of the water storage tank 1 that connects with the outside, thus controlling the internal pressure of the water storage tank 1. When the vent 2 is rotated and the top of the water storage tank 1 is not connected to the outside, the sewage is injected into the water storage tank 1 and sinks to the bottom of the water storage tank 1. A closed space is formed between the sewage and the space above the water storage tank 1. As sewage is continuously injected, the internal pressure of the water storage tank 1 will increase. After opening the outlet pipe 13 for discharging filtered water and the pipe for discharging dirt and impurities, the sewage is squeezed through the mesh cylinder 14 and discharged, thereby promoting filtration. With the rotating component 5, a more efficient sewage collection efficiency can be obtained, and clogging can be avoided, making it convenient for continuous use of the device. After long-term use, the top cover 12 can also be opened to maintain and clean the inside of the water storage tank 1.

[0033] Please see Figures 1-2 , Figures 5-6 In this embodiment of the utility model, a first vent hole is provided through the flow limiting plate 17, the vent cylinder 2 is a cylindrical structure, one end of the vent cylinder 2 is disposed opposite to the flow limiting plate 17, and a second vent hole corresponding to and adapted to the first vent hole is provided through it, the other end of the vent cylinder 2 is inlaid with a metal mesh, and the periphery of the vent cylinder 2 is rotatably connected to the upper cover 12.

[0034] In this embodiment, the first vent on the flow-limiting plate 17 is a fan-shaped hole, but other types such as round or square holes can also be used. The coverage area of ​​the first vent on the flow-limiting plate 17 and the coverage area of ​​the second vent on the vent cylinder 2 are arranged opposite to each other. The coverage area of ​​the first vent is greater than or equal to the coverage area of ​​the second vent. At the same time, the coverage areas of the first and second vents are not greater than half the area of ​​the opposite sides of the flow-limiting plate 17 and the vent cylinder 2. In this way, when the vent cylinder 2 and the flow-limiting plate 17 rotate relative to each other, the connection area can be adjusted, and the vent cylinder 2 and the flow-limiting plate 17 can be closed by rotating.

[0035] Please see Figures 1-4In this embodiment of the utility model, the rotating component 5 includes an outer ring 51 and an inner ring 52 arranged concentrically. The outer ring 51 is rotatably connected to the inner wall of the water storage cylinder 1 through a bearing. The inner ring 52 is rotatably connected to the upper end of the mesh cylinder 14 through a bearing. Multiple sets of connecting rods are connected between the outer ring 51 and the inner ring 52. An impeller 53 is fixedly connected to the inner wall of the inner ring 52.

[0036] In this embodiment, preferably, the connecting rod can be a round rod, a square rod, or a rod with a "T" shaped cross section. When the sewage passes upward through the guide bucket 15 and the impeller 53, it can drive the impeller 53 and the inner ring 52 to rotate synchronously. The inner ring 52 drives the outer ring 51 to rotate through the connecting rod. This rotation can drive the sewage to rotate centrifugally, which can promote the sedimentation and concentration of dirt, and also prevent impurities from adhering to the surface of the screen cylinder 14.

[0037] In this embodiment, preferably, a vertically downward brush can be added to the connecting rod. The brush is set in contact with the surface of the screen cylinder 14. When the outer ring 51, inner ring 52 and connecting rod rotate synchronously, the brush can be driven to rotate, thereby further utilizing the brush to stir the sewage rotation. At the same time, the brush cleans the surface of the screen cylinder 14, which has a better effect in preventing dirt adhesion.

[0038] Please see Figure 1 , Figures 7-8 In this embodiment of the invention, the water receiving trough 4 is a strip-shaped structure with a right-angled trapezoidal cross-section. One side of the trough 4 is open, located at the hypotenuse of the trapezoid. A water guide hole 41 is provided through the bottom of the right-angled side of the trough 4. An assembly groove 44 is embedded in the outer side of the trough 4, located around the water guide hole 41. This design allows for stable sampling even when the trough 4 is placed at the bottom of the sewage tank.

[0039] In this embodiment, the input end of the water pump 3 can be movably snapped into the assembly groove 44 around the water guide hole 41. The input end of the water pump 3 can be fixed in the assembly groove 44 with screws or the like. The water guide hole 41 is located in the middle of the bottom side of the right-angled edge surface of the water receiving tank 4, which facilitates assembly and also facilitates the unified collection of sewage and dirt.

[0040] Please see Figure 1 , Figures 7-8 In this embodiment of the present invention, a second guide block 43 is provided at the right-angled edge of the water receiving tank 4. The second guide block 43 is arranged with an arc-shaped concave surface facing the opening of the water receiving tank 4. A through hole corresponding to the water guiding hole 41 is passed through the middle of the second guide block 43. A first guide block 42 is fixedly attached to the bottom of the water receiving tank 4. The first guide block 42 is located on the side of the second guide block 43 away from the water guiding hole 41. The upper surface of the first guide block 42 is arranged with an arc-shaped concave surface.

[0041] In this embodiment, preferably, the sewage can be concentrated towards the center through the first guide block 42, and with the cooperation of the second guide block 43, the sewage gradually concentrates at the guide hole 41, which makes the collection efficiency higher and makes it less likely for dirt to accumulate.

[0042] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
