Description

Technical Field

[0001] This utility model relates to the field of wastewater sampling, and in particular to a continuous wastewater sampling device equipped with anti-clogging function. Background Technology

[0002] In fields such as environmental monitoring, industrial emission control, and wastewater treatment, continuous wastewater sampling is a crucial technology. By continuously sampling wastewater, dynamic data on pollutant concentration changes over time can be obtained, thereby more accurately assessing water quality, total discharge, and the operational effectiveness of treatment systems.

[0003] Currently, most common wastewater sampling equipment adopts intermittent or timed sampling methods. During long-term operation, the sampling pumps and pipeline systems are prone to blockage due to impurity deposition or particulate matter accumulation. Traditional sampling equipment often lacks effective anti-blocking mechanisms when encountering wastewater with high viscosity or high suspended solids content.

[0004] Therefore, this utility model provides a wastewater continuous sampling device equipped with anti-clogging function to solve the above-mentioned technical problems. Utility Model Content

The third connecting ring is installed on the second connecting ring, the protective plate is installed on the front of the third connecting ring, and multiple connecting blocks are fixedly connected to the rear side of the protective plate.

[0008] More preferably, it also includes a protective housing, with the protective housing mounted on the second connecting ring.

[0009] More preferably, it also includes an observation window, with an observation window embedded at the rear of each sampling frame.

[0010] More preferably, it also includes casters, with casters symmetrically installed on the front and rear sides of the bottom of the frame.

[0011] More preferably, all rotating blades are cutting blades.

[0012] The beneficial effects of this utility model are as follows: 1.

Detailed Implementation

[0021] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0022] Example: A continuous wastewater sampling device equipped with anti-clogging function, such as Figures 1-6As shown, the system includes a frame 1, sampling frames 2, a water pump 3, a suction pipe 4, an outlet pipe 5, a drain pipe 6, a valve 7, a connecting pipe 8, an electronic valve 9, a flange 10, a first connecting ring 11, a filter screen 12, a second connecting ring 13, a rotating shaft 14, a rotating plate 15, a waterproof motor 16, a third connecting ring 17, a protective plate 18, a connecting block 19, a protective outer shell 20, an observation window 21, and casters 22. Three sampling frames 2 are fixedly connected to the upper part of the frame 1. These three sampling frames 2 are used to collect wastewater samples from the surface, middle, and deep layers, respectively. A water pump 3 is installed at the bottom inside the frame 1, and a suction pipe 4 is installed in front of the water pump 3. The middle sampling frame 2 is fixedly connected to the front of a water outlet pipe 5, and the other end of the water outlet pipe 5 is fixedly connected to the outlet of the water pump 3. Each of the three sampling frames 2 is fixedly connected to the bottom of a drain pipe 6, and a valve 7 is installed at the rear of each drain pipe 6. The valve 7 controls the opening and closing of the drain pipe 6. The front of the sampling frames 2 on both the left and right sides is fixedly connected to connecting pipes 8, and the other ends of both connecting pipes 8 are fixedly connected to the water outlet pipe 5. Electronic valves 9 are installed on both connecting pipes 8 and the water outlet pipe 5, and the electronic valves 9 control the opening and closing of different sampling paths. A flange 10 is fixedly connected to the front of the water pump pipe 4, and a flange 10 is installed at the front of the flange 10. The system is equipped with a first connecting ring 11, inside which a filter screen 12 is installed. The filter screen 12 can filter floating debris (such as plastic) in the wastewater, preventing it from entering the sampling system and causing pipe blockage. A second connecting ring 13 is fixedly connected to the front of the first connecting ring 11. Multiple rotating shafts 14 are rotatably connected to the front of the second connecting ring 13. The rotating shafts 14 can drive rotating blades 15 to rotate, thereby cutting the floating debris. Multiple rotating blades 15 are fixedly connected to each rotating shaft 14. The rotating blades 15 can rotate and cut the floating debris in the wastewater, preventing it from clogging the filter screen 12 and the pipes. All blades 15 are cutting blades. A waterproof motor 16 is installed on the second connecting ring 13. A third connecting ring 17 is installed on the second connecting ring 13. A protective plate 18 is installed at the front of the third connecting ring 17. Multiple connecting blocks 19 are fixedly connected to the rear of the protective plate 18. A protective shell 20 is installed on the second connecting ring 13. An observation window 21 is embedded at the rear of each sampling frame 2. The observation window 21 allows the operator to observe the water sample status in the sampling frame 2 in real time to ensure that the sampling is carried out normally. Universal wheels 22 are symmetrically installed on the front and rear sides of the bottom of the frame 1. The universal wheels 22 facilitate the movement of the equipment between different sampling areas.

[0023] The operator first moves the device to the target sampling area using the casters 22 at the bottom of the unit. Then, the brakes on the casters 22 are locked to ensure the device remains stable and does not shift during sampling. The pump pipe 4 is placed into the wastewater to be sampled, ensuring the inlet of the pump pipe 4 is at the desired water layer. The pump 3 is started. When surface wastewater sampling is required, the electronic valve 9 on the outlet pipe 5 is opened, allowing the surface wastewater to be drawn in by the pump 3 and enter the intermediate sampling frame 2 through the pump pipe 4 and outlet pipe 5. When mid-layer sampling is required, the electronic valve 9 on the outlet pipe 5 is closed, and the electronic valve 9 on the left connecting pipe 8 is opened. At this time, mid-layer wastewater enters the left sampling frame 2 through the pump 3, pump pipe 4, and left connecting pipe 8. When deep layer sampling is required, the electronic valve 9 on the left connecting pipe 8 is closed, and the electronic valve 9 on the right connecting pipe 8 is opened. Deep layer wastewater enters the right sampling frame 2 through the pump 3, pump pipe 4, and right connecting pipe 8. In frame 2, to prevent the water pumping pipe 4 or the filter screen 12 from being blocked by floating debris, the waterproof motor 16 can be activated during the sampling process. The waterproof motor 16 drives the rotating shaft 14 to rotate through the output shaft. The rotating shaft 14 drives multiple rotating plates 15 to rotate synchronously. The rotating plates 15 on the upper rotating shaft 14 can push the rotating plates 15 on the left and right sides to rotate in tandem, achieving overall synchronous rotation. During the rotation of the rotating plates 15, floating debris such as plastic adsorbed on the filter screen 12 can be effectively broken up, thereby avoiding blockage. The filtered wastewater enters the sampling frame 2 through the filter screen 12, and the debris is effectively intercepted, preventing pipe blockage and ensuring smooth sampling. The operator can check the water sample status in the sampling frame 2 in real time through the observation window 21 to ensure that the sampling process is normal. After sampling is completed, the water pump 3, each electronic valve 9 and the waterproof motor 16 are turned off in sequence. If it is necessary to drain the wastewater in the sampling frame 2, the valve 7 on the drain pipe 6 can be opened to allow the wastewater to drain smoothly.
