Description

Technical Field

[0001] This utility model relates to the field of detection technology, and in particular to a nitrogen and phosphorus detection device for circulating water main pipes. Background Technology

[0002] The main circulating water pipe is the primary pipeline in the circulating water system. It is responsible for transporting circulating water from the source to various water usage points and collecting used water to return it to the treatment system for reuse. It is a key component connecting various circulating water components, ensuring that the entire circulating water system can operate efficiently and stably. Nitrogen and phosphorus detection is the process of determining and analyzing the nitrogen and phosphorus content in a sample. This detection has wide applications in many fields, including but not limited to agriculture, environmental protection, petrochemicals, food science, and clinical medicine. Circulating water plays a vital role in industrial production processes. If there are problems with the quality of circulating water, such as excessive nitrogen and phosphorus content, it may affect the normal operation of production equipment and even lead to equipment damage or production stoppage.

[0003] A search revealed that Chinese Patent CN218524407U discloses a sampling and detection device for nitrogen and phosphorus content in wastewater. Most existing wastewater sampling and detection devices are portable devices housed in a briefcase, combining sampling and sample detection functions. However, the sampling components are mostly test tubes or measuring cups, requiring manual insertion into the wastewater. When the wastewater surface is far from the operator's position, additional sampling tools are needed, making wastewater collection inconvenient. Therefore, this foldable sampling component eliminates the need for additional sampling devices. The operator simply inserts a pumping pipe into the wastewater and uses a manual pumping mechanism to draw the wastewater into the sampling and storage section. The operator can quickly and safely complete the operation while standing beside the wastewater pool.

[0004] The aforementioned detection device facilitates water sampling. However, in the prior art, when detecting nitrogen and phosphorus in main pipeline water, it is usually necessary to filter the water sample and then transport the filtered water to the detection device for testing. This process is cumbersome and time-consuming, reducing the efficiency of water sample testing. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a nitrogen and phosphorus detection device for circulating water main pipes.

[0015] As a further description of the above technical solution:

[0016] The mounting groove is rotatably connected to a stud, the stud is threadedly connected to a movable block, and a first limiting plate is fixedly connected to the upper surface of the movable block.

[0017] As a further description of the above technical solution:

[0018] A handle is fixedly connected to one end of the stud, and a second limiting plate is fixedly connected to the upper surface of the base plate. The second limiting plate is located on one side of the first mounting bracket.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model, through the setting of the filter component, adds the function of facilitating the filtration of the extracted water sample before testing. It eliminates the need for the water sample to be filtered at other stations before being transported to the testing device, thereby improving the convenience of the testing process and helping to improve the efficiency of testing. At the same time, it facilitates the disassembly and replacement of the filter screen, which helps to clean the filter screen in a timely manner. It also facilitates the stirring of the water sample during the filtration process and the scraping of the filter screen surface, thereby reducing the phenomenon of filter screen clogging during the filtration process.

[0021] 2. By setting up a limiting component, this utility model facilitates the clamping and fixing of the testing cup during the testing process. This helps reduce the phenomenon that the base plate shakes due to external forces during the testing process, causing the testing cup to wobble and become unstable, thus affecting the testing accuracy. This improves the stability of the testing process and thus enhances the accuracy of the data. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] As attached Figure 1-6 As shown, one embodiment of this utility model provides a nitrogen and phosphorus detection device for a circulating water main, including a base plate 1. A first mounting bracket 2 is fixedly connected to the upper surface of the base plate 1. A detection head 3 is fixedly installed on one side of the first mounting bracket 2. A detection cup 4 is provided on the upper surface of the base plate 1 and is located on one side of the first mounting bracket 2. A second mounting bracket 5 is fixedly connected to the upper surface of the base plate 1 and is located on one side of the first mounting bracket 2. A hydraulic cylinder 6 is fixedly installed on the upper surface of the second mounting bracket 5. A motor 7 is fixedly connected to the output end of the hydraulic cylinder 6. A filter assembly is provided at the output end of the motor 7. The detection cup 4 is used to hold water samples. The hydraulic cylinder 6 facilitates the up-and-down movement of the scraper 9, and the motor 7 facilitates the rotation of the scraper 9.

[0032] As attached Figure 3 As shown, the filter assembly includes a rotating rod 8, which is fixedly connected to the output end of the motor 7. A scraper 9 is fixedly connected to one end of the rotating rod 8. A filter cup 10 is fixedly connected to one side of the second mounting bracket 5. Mounting plates 11 are provided on both sides of the filter cup 10. Filter screens 12 are fixedly connected to the lower surfaces of the two mounting plates 11. A threaded sleeve 13 is connected through the middle of the mounting plate 11. A bolt 14 is connected to the internal thread of the threaded sleeve 13. A flow tube 15 is connected through one side of the filter cup 10. A rotating sleeve 16 is rotatably connected to one side of the flow tube 15. The rotating rod 8 facilitates the rotation of the scraper 9. The filter cup 10 facilitates the holding of water samples during filtration. The bolt 14 facilitates the fixing of the mounting plate 11 through the threaded sleeve 13. The rotating sleeve 16 facilitates the connection with the threaded tube 17.

[0033] As attached Figure 5 As shown, a threaded tube 17 is connected through one side of the test cup 4, and a rotating sleeve 16 is threaded to the outside of the threaded tube 17, which facilitates the flexible assembly and disassembly of the test cup 4.

[0034] As attached Figure 6As shown, a limiting component is provided on the upper surface of the base plate 1. The limiting component includes a mounting groove 18, which is formed on the upper surface of the base plate 1. A stud 19 is rotatably connected inside the mounting groove 18, and a moving block 20 is threadedly connected to the outside of the stud 19. A first limiting plate 21 is fixedly connected to the upper surface of the moving block 20. A handle 22 is fixedly connected to one end of the stud 19. A second limiting plate 23 is fixedly connected to the upper surface of the base plate 1. The second limiting plate 23 is located on one side of the first mounting bracket 2. The mounting groove 18 facilitates the installation of the stud 19, and the moving block 20 facilitates the movement of the first limiting plate 21 towards the side of the detection cup 4. The second limiting plate 23 facilitates the limiting of the other side of the detection cup 4.

[0035] Working principle: During testing, the water sample is first extracted from the main water pipe and then poured into the filter cup 10. The hydraulic cylinder 6 and motor 7 are activated, causing the output end of the hydraulic cylinder 6 to drive the motor 7 downward. The motor 7 then drives the scraper 9 to move to the surface of the filter screen 12 via the rotating rod 8. The output end of the motor 7 drives the rotating rod 8 to rotate, which in turn drives the scraper 9 to rotate on the surface of the filter screen 12. This facilitates the stirring of the water sample while scraping the surface of the filter screen 12, thereby reducing the phenomenon of clogging on the surface of the filter screen 12. After the water sample passes through the filter screen 12 and reaches the bottom of the filter cup 10, it will reach the interior of the detection cup 4 through the connection of the flow pipe 15. Then, the detection head 3 is activated to test the processed water sample.

[0036] When disassembling and replacing the filter screen 12, first use the output end of the hydraulic cylinder 6 to drive the motor 7 to move upward, so that the motor 7 drives the rotating rod 8 and scraper 9 to move upward. Then, tighten the bolt 14 so that the bolt 14 rotates and disengages inside the threaded sleeve 13. Then lift the mounting plate 11 so that the two mounting plates 11 can move the filter screen 12 out of the filter cup 10, thus facilitating the disassembly of the filter screen 12.

[0037] When clamping the filter cup 10, turn the handle 22 so that the handle 22 drives the stud 19 to rotate. When the stud 19 rotates, it drives the moving block 20 to move inside the mounting groove 18. This allows the moving block 20 to move the first limiting plate 21 closer to one side of the test cup 4. At the same time, under the limitation of the second limiting plate 23, it is easy to clamp and fix the test cup 4, which improves the stability of the test cup 4 during use.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
