Description

Technical Field

[0001] This invention relates to the field of ammonia nitrogen detection technology, specifically to a precise continuous feed ammonia nitrogen analyzer. Background Technology

[0002] Ammonia nitrogen is a key indicator in water pollution monitoring, industrial wastewater treatment, and environmental quality assessment. The accuracy and efficiency of its measurement results directly affect pollution control decisions and the effectiveness of environmental supervision. With the continuous improvement of environmental protection requirements and the surge in demand for batch sample testing in scenarios such as water quality monitoring and industrial quality inspection, traditional ammonia nitrogen analyzers can no longer meet the needs for precise, continuous, and automated testing, and have gradually exposed many technical bottlenecks.

[0003] The shortcomings of traditional ammonia nitrogen analyzers are as follows: traditional instruments require manual transfer of sample tubes to the testing station one by one, and manual removal after sample injection. This is cumbersome, time-consuming and labor-intensive for batch testing. At the same time, the pure water calibration step before testing also requires manual handling of the pure water tubes. Multiple manual interventions lead to a break in the testing process, making continuous sample injection and testing impossible and restricting the efficiency of batch sample testing.

The hinge seat then rotates the entire unit, allowing for multi-dimensional adjustments in lifting, angle, and rotation to accommodate marking needs of different test tube sizes. The flexible hinge connection ensures precise bonding of the bonding component to the test tube's outer wall, guaranteeing flatness and firmness of the marking. The pressure roller and bonding roller work together to tightly adhere the marking layer to the test tube's outer wall, resulting in a smooth, edge-free, and non-detachable finish, improving marking standardization. The adhesive layer can be printed with and binds test data, leaving no adhesive residue after application. This ensures accurate and traceable binding of sample test information, eliminating errors and omissions caused by manual marking.

[0016] 3. Extraction Component: The active gripper drives the connecting arm and clamping feet to retract and open, securely holding sample tubes of different diameters, achieving non-destructive gripping and fixing of sample tubes, and ensuring no slippage or displacement during transport. The tray supports the gripper structure and, with the adjustment unit, completes horizontal, vertical, and lifting displacement, enabling precise transfer of sample tubes from the storage unit to the detection unit, ensuring continuous sample injection efficiency.

A guide rod 629 is fixedly mounted inside the mounting shell 621 between the placement shaft 622 and the bonding wheel 625. A take-up shaft 626 is rotatably mounted outside the mounting shell 621, and a guide rod assembly 628 is fixedly mounted inside the outer mounting shell 621 of the take-up shaft 626.

[0050] The placement shaft can retract the marking components, the peeling plate can accurately peel the marking adhesive layer from the base layer and the isolation layer, and the bonding roller, together with the pressure roller, can roll and adhere the peeled marking layer to the outer wall of the test tube, realizing automated operation of marking, peeling and pasting, replacing manual operation, and improving marking efficiency and flatness; The guide rod and guide rod assembly provide an orderly guide path for the marking components, and the take-up shaft can automatically rewind the peeled isolation layer and base layer to avoid component tangling and jamming, ensuring continuous marking operations; The design of the labeling port and pressure roller is adapted to the outer wall of the sample tube, which can achieve a tight fit between the labeling layer and the tube, avoid labeling detachment and edge lifting, and improve the standardization of labeling.

[0051] In this embodiment, a marking component 630 is wound on the shaft 622. The marking component 630 is composed of an isolation layer 631, a base layer 632, and a marking adhesive layer 633. The base layer 632 and the marking adhesive layer 633 are jointly attached to the base layer 632, and the marking adhesive layer 633 can be detachably disposed within the base layer 632. A peeling plate 624 is used to peel off the marking adhesive layer 633 on the isolation layer. A pressure roller 623 is used to roll the peeled marking adhesive layer 633.

[0052] The marking component adopts a layered structure of an isolation layer, a base layer, and a marking adhesive layer. The peeling plate can quickly separate the marking adhesive layer from the other layers. The peeling process is smooth and non-sticky, which greatly improves the marking peeling efficiency. The labeling adhesive layer can support the printing of test information, achieving precise binding between test data and the labeling layer. After pasting, it can firmly adhere to the outer wall of the sample tube, leaving no adhesive residue and is not easy to fall off, ensuring the traceability of sample test information. The rewinding shaft can centrally rewind the stripped isolation layer and base layer, keeping the instrument's interior clean and preventing waste layers from scattering and contaminating the testing environment, while also enabling the orderly recycling of consumables.

[0053] Working principle and usage process of this invention: S1. Personnel remove the secondary storage rack 312 on the partition 313, take out the sample tube 900 without samples, open the sealing cap on the sample tube 900 and pour in the sample to be tested. Then, personnel orderly insert the sample tubes 900 containing samples into the sample placement box 322, ensuring that the sample tubes 900 pass through the positioning frame 323. Finally, personnel can place the sample placement box 322 into the limiting foot 321 using the carrying handle 324 to achieve limiting constraint on the sample placement box 322. Personnel manually open the cover 205 to open the placement slot 203 and start the detection host 201 through the display control module 202, causing the detection host 201 to enter the detection process. S2. Before the sample is tested, the personnel need to perform a verification. The verification method is as follows: Start the drive spindle 514 in the mounting ear 513, which drives the flipping frame 511 to rotate from the vertical state to the horizontal state. When switching to the horizontal state, the fixed shaft 522 will be affected by the weight of the pure water test tube 700 and enter the drooping state as it rotates, so that the pure water test tube 700 corresponds to the lower delivery port 204. Start the telescopic cylinder 515 to push the hanger 516, so that the pure water test tube 700 suspended at the end of the hanger 516 will be lowered and inserted into the delivery port 204. After the detection host 201 has completed the verification, the pure water test tube 700 can be reset again according to the above steps for subsequent sample testing. S3. At this time, activate active slide rail 1 403 and active slide rail 2 404. Utilize the horizontal and vertical adjustment between active slide rail 1 403 and active slide rail 2 404 to make the suspended support plate 801 reach the corresponding sampling point, ensuring that clamping foot 2 804 is synchronously aligned. Then, activate telescopic cylinder 1 405 to extend synchronously and telescopic plate 406 to descend synchronously, causing clamping foot 2 804 to descend to both sides of sample tube 900. Then, drive connecting arm 803 to retract via active gripper 802, and clamping foot 2 804 to clamp and fix sample tube 900, completing the extraction of sample tube 900. After extraction, it can be retrieved and reset again via telescopic cylinder 1 405. By adjusting the horizontal and vertical alignment between the active slide rail 1 403 and the active slide rail 2 404, the extracted sample tube 900 is moved to the position corresponding to the delivery port 204. Finally, the extension and descent of the telescopic cylinder 1 405 causes the sample tube 900 to be inserted into the delivery port 204. At this time, the personnel can perform the test on the inserted sample tube 900 by operating the display control module 202 on the detection host 201. After the test is completed, the detection host 201 pushes the test data to the marking unit 600, and the marking unit 600 enters the marking state. S3. During the test, after the test is completed, the tested sample tube 900 can be clamped and pulled out. During the recycling process, the motor on the winding shaft 626 is started to perform the winding operation. The placement shaft 622 is subjected to tension and rotates synchronously. The marking component 630 on the placement shaft 622 is conveyed and guided by the guide rod 629 into the space between the peeling plate 624 and the bonding wheel 625. At the same time, the print head prints the pushed information onto the marking adhesive layer 633. The rolling guide of the bonding wheel 625 causes the marking component 630 to be guided along the surface of the peeling plate 624 until it reaches the outer end of the peeling plate 624. Under the action of the edge of the peeling plate 624, the marking adhesive layer 633 causes the base layer 632 and the isolation layer 631 to separate. The isolation layer 631 and the base layer 632 are then recycled along the other side of the peeling plate 624. Finally, the winding shaft 626 is wound up under the guidance of the guide rod group 628. The hinge cylinder 612 is activated to push the rear side of the mounting shell 621. The mounting shell 621 uses the hinge with 615 to change its direction. At that time, the front side of the mounting shell 621 will extend under the driving force, causing the pressure roller 623 to come into contact with the sample tube 900 on the front side. At that time, the end of the marking adhesive layer 633 will be pressed onto the sample tube 900 by the pressure roller 623. Finally, the hinge seat 614 can be activated to push the tray 801. At that time, the hoisted mounting shell 621 will drive the internal pressure roller 623 to roll along the outside of the sample tube 900, so that the marking adhesive layer 633 is attached to the sample tube 900. In this way, the information of the sample tube 900 after the test will be recorded synchronously. Once the sample tubes 900 in the sample placement box 322 have been tested, personnel can remove them and place the tested sample tubes 900 in their respective secondary storage racks 312. Then, the personnel hold the pure water test tube 700 and rotate the threaded adjustment rod 523. The threaded adjustment rod 523 uses its own opposing threads to drive the vertical plate 521 in opposite directions, causing the vertical plate 521 to drive the bottom clamp 524 to expand outward, thereby releasing the clamping and fixing of the pure water test tube 700 and completing its recovery.
