Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and more specifically, to an online nitrate analyzer. Background Technology

[0002] In the field of water pollution monitoring, accurate detection of nitrate content is crucial for assessing water quality, protecting the ecological environment and human health. Currently, there are various devices and technologies available on the market for analyzing nitrate in wastewater. Among them, spectroscopic detection has been widely used due to its advantages such as non-invasiveness, high sensitivity, and fast analysis speed.

[0003] Traditional nitrate analysis equipment based on spectroscopic detection methods mostly employs a sequential testing approach, where a single container of wastewater sample is placed between the light source and the detector. After each test, the sample must be manually replaced before the next sample can be tested. This operational mode has several significant drawbacks: Firstly, the testing efficiency is extremely low. For scenarios requiring the processing of large numbers of wastewater samples, such as daily monitoring of urban wastewater treatment plants or centralized wastewater discharge monitoring in industrial parks, sequential testing of single samples consumes a significant amount of time, making it difficult to meet the needs for rapid acquisition of test results and timely treatment of wastewater or adjustment of production processes. Secondly, frequent manual intervention in the sample replacement process not only increases labor costs but also easily introduces errors due to improper human operation, affecting the accuracy and reliability of the test results. For example, sample contamination or inaccurate sample quantity may occur during sample transfer. Utility Model Content

[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] like Figures 1 to 8 As shown, this utility model provides an online nitrate analyzer, comprising:

[0032] The housing 1 has a support 2 and a photoelectric detector 23 fixedly installed inside it. A fixing block 21 is fixedly installed on the inner wall of the housing 1. A xenon flash lamp 22 is fixedly installed at the bottom of the fixing block 21 and is located directly above the photoelectric detector 23.

[0033] The drive mechanism is located inside the support 2.

[0034] A rotating mechanism is located at the top of support 2;

[0035] The rotating mechanism includes a fixed shaft 3, the bottom end of which is fixedly connected to the top end of the support 2. A rotating disk 4 is fixedly sleeved on the outer surface of the fixed shaft 3. An arc-shaped groove 5 and a long groove 6 are respectively opened on the outer surface of the rotating disk 4. A hexagonal block 7 is fixedly installed on the top end of the rotating disk 4. A circular plate 8 is movably connected to the top end of the rotating disk 4. The bottom end of the circular plate 8 is movably sleeved on the outer surface of the hexagonal block 7. A buckle 9 is fixedly installed on the top end of the circular plate 8. A test tube 10 is snapped into the inside of the buckle 9.

[0036] When the xenon flash lamp 22 is running, it will illuminate the photodetector 23. Since the light emitted by the xenon flash lamp 22 can be absorbed by nitrates, when the test tube 10 is located between the xenon flash lamp 22 and the photodetector 23, the light received by the photodetector 23 will be reduced, thus enabling the detection and analysis of nitrates. When the rotating disk 4 rotates around the fixed shaft 3, it will drive the circular plate 8 to rotate through the hexagonal block 7. At this time, the circular plate 8 will drive several test tubes 10 to rotate through several buckles 9. When several test tubes 10 rotate sequentially between the xenon flash lamp 22 and the photodetector 23, they will be detected and analyzed.

[0037] The drive mechanism includes:

[0038] Motor 11, the top of motor 11 is fixedly connected to the inside of support 2, and the output end of motor 11 is fixedly sleeved with rotating shaft 12;

[0039] The rotating plate 13 has its bottom end fixedly sleeved with the top end of the rotating shaft 12. An arc-shaped block 14 and a rotating rod 15 are fixedly installed on the top end of the rotating plate 13. The outer surface of the arc-shaped block 14 fits into the interior of the arc-shaped groove 5.

[0040] When the motor 11 runs, the shaft 12 will drive the rotating plate 13 to rotate. At this time, the rotating plate 13 will simultaneously drive the arc block 14 and the rotating rod 15 to rotate. When the arc block 14 contacts the inside of the arc groove 5, it will block the rotation of the entire rotating disk 4. When the arc block 14 disengages from the inside of the arc groove 5 during rotation, the rotating rod 15 will move into the inside of the long groove 6 during rotation. At this time, the rotating rod 15 will push the inside of the long groove 6 to make the entire rotating disk 4 rotate around the fixed shaft 3. When the outer surface of the arc block 14 re-contacts the inside of the arc groove 5 during rotation, the entire rotating disk 4 will stop rotating. At the same time, the rotating rod 15 will rotate out of the inside of the long groove 6, thus achieving the effect of intermittent rotation of the entire rotating disk 4. At this time, the test tube 10 will be located between the xenon flash lamp 22 and the photodetector 23, thus enabling the test tube 10 to be detected and analyzed.

[0041] The circular plate 8 has a first magnet 17 fixedly sleeved inside the bottom end, and a second magnet 18 is attracted to the bottom end of the first magnet 17. The outer surface of the second magnet 18 is fixedly sleeved inside the top end of the rotating disk 4.

[0042] The design of the first magnet 17 and the second magnet 18 will make the assembly of the rotating disk 4 and the circular plate 8 more stable.

[0043] The top of the circular plate 8 is fixedly fitted with a handle 16, the inside of which is made of rubber.

[0044] The design of the handle 16 makes it easier for the operator to move the circular plate 8 as a whole. Since the handle 16 is made of rubber, it is more comfortable for the operator to pull the handle 16.

[0045] The test tube 10 has a sealing plug 19 inside, and a pull ring 20 is fixedly installed on the outer surface of the sealing plug 19.

[0046] The design of the sealing plug 19 makes it easy for operators to seal the wastewater inside the test tube 10, preventing the wastewater from flowing out of the test tube 10 during analysis. The design of the pull ring 20 makes it easy for operators to remove the sealing plug 19 from the test tube 10.

[0047] Ventilation openings 24 are provided on the outer surface of the housing 1, and casters 25 are provided at the bottom of the housing 1.

[0048] The design of the vent 24 will enhance the heat dissipation effect of the equipment, and the design of the casters 25 will make it easier for operators to move the equipment.

[0049] The front of the casing 1 is movably mounted with a rotating door 26, and a display 27 is installed on the rotating door 26.

[0050] The design of the rotating door 26 allows the interior of the housing 1 to be sealed, thus preventing external light from affecting the detection structure. The design of the display 27 allows the detection and analysis data to be displayed on the display 27, making it convenient for operators to observe and record.

[0051] The control panel 28 is installed inside the front of the casing 1, and the control panel 28 contains a controller and a data processor.

[0052] Due to the design of the control panel 28, it is convenient for operators to operate the equipment. When the photodetector 23 sends the light signal to the data processor, the data processor will convert it into corresponding data. Then, this data will be transmitted to the controller, and the controller will display the data on the display 27. After all the test tubes 10 have been tested, the controller will stop the xenon flash lamp 22, the photodetector 23 and the motor 11.

[0053] Working principle and usage process of this utility model:

[0054] When operators need to analyze nitrates in wastewater, they first fill test tube 10 with wastewater. Then, they insert the sealing plug 19 into test tube 10, sealing the wastewater inside. Next, they place test tube 10 on top of the clip 9 and press it down, securing it in place. After installing all test tubes 10, the operator lifts the circular plate 8 using handle 16 and places it on top of the rotating disk 4, ensuring the bottom of the circular plate 8 aligns with the top of the rotating disk 4. During the bonding process, the outer surface of the hexagonal block 7 will fit onto the inside of the bottom of the circular plate 8. Simultaneously, several first magnets 17 will attract several second magnets 18. The design of the first magnets 17 and second magnets 18 enhances the stability of the connection between the circular plate 8 and the rotating disk 4. Then, the operator activates the xenon flash lamp 22 and the photodetector 23. The xenon flash lamp 22 will then illuminate the photodetector 23. Next, the operator starts the motor 11. The rotating shaft 12 will then drive the rotating plate 13 to rotate. The rotating plate 13 will simultaneously drive the arc-shaped block 14 and the rotating rod 15 to rotate. Due to the arc-shaped block... The design of the arc block 14 and the arc groove 5 is such that when the outer surface of the arc block 14 contacts the interior of the arc groove 5, the arc block 14 will block the rotation of the entire rotating disk 4 through the arc groove 5. When the outer surface of the arc block 14 loses contact with the interior of the arc groove 5 during rotation, the rotating rod 15 will move into the interior of the long groove 6 during rotation. At this time, the rotating rod 15 will squeeze and push the interior of the long groove 6 during rotation, thereby causing the entire rotating disk 4 to rotate around the fixed axis 3. At the same time, the rotating disk 4 will drive the circular plate 8 to rotate through the hexagonal block 7. When the outer surface of the arc block 14 re-contacts the interior of the arc groove 5 during rotation... Upon contact, the rotating rod 15 will simultaneously rotate out of the interior of the long groove 6, thereby causing the rotating disk 4 to stop rotating as a whole. This achieves the effect of intermittently rotating several test tubes 10. When the rotating disk 4 stops rotating as a whole, the test tubes 10 will be located between the xenon flash lamp 22 and the photodetector 23. Since nitrate can absorb the light emitted by the xenon flash lamp 22, the amount of light that the photodetector 23 can receive is reduced. At this time, the photodetector 23 can calculate the nitrate content in the wastewater based on the difference in the amount of light received, thus realizing the function of batch detection and analysis of wastewater.

[0055] Subsequently, the photodetector 23 sends a signal to the data processor built into the control panel 28. The data processor then converts the received signal into corresponding data and sends it to the controller built into the control panel 28. At this time, the controller will display the data on the display 27 for the operator to observe and record. Since the number of test tubes 10 that the circular plate 8 can hold is fixed, when the detection and analysis of all test tubes 10 is completed, the photodetector 23 will send a signal to the controller. At this time, the controller will stop the xenon flash lamp 22, the photodetector 23 and the motor 11 from running.
