Description

Technical Field

[0001] The present invention relates to the technical field of ammonia concentration detection, and in particular to a device and method for detecting ammonia concentration. Background Art

[0002] The so-called ammonia water refers to an aqueous solution of gaseous ammonia. It is a colorless, transparent liquid with a pungent odor. The density of ammonia water is lower than that of water. It is unstable, volatile, and easily decomposed by light or heat. Ammonia water itself is a non-flammable and explosion-proof liquid. The ammonia gas separated from water has a strong pungent odor and is irritating and corrosive to the human eyes, nose, and skin, and is also burning and explosive.

[0003] Patent announcement number CN219978248U discloses a device for rapid detection of ammonia concentration, including an ammonia concentration detector, a No. 1 connection block fixedly connected to the rear right end of the ammonia concentration detector, a placement mechanism fixedly connected to the end of the No. 1 connection block away from the ammonia concentration detector, a detection tube connected to the placement mechanism, a No. 2 connection block fixedly connected to the middle of the left and right ends of the ammonia concentration detector, two No. 2 connection blocks fixedly connected to the ends away from the ammonia concentration detector, and a stabilizing mechanism threadedly connected to the middle of the upper ends of the two fixing blocks. The placement mechanism facilitates the placement of the detection tube, making it easy to pick up the detection tube when it is needed to hold ammonia for testing, avoiding adverse consequences caused by taking the wrong detection tube in the laboratory.

[0004] When the above device detects the concentration of ammonia water, the detection cylinder is conveniently placed to improve the convenience of taking it. However, in the specific ammonia water concentration detection work, when one round of detection operation is completed and the next round of detection is required, after pouring out the ammonia solution of the previous round in the detection cylinder, in order to avoid the residual solution from affecting the detection value of the next round, the detection cylinder often needs to be cleaned before the next step can be performed. The above device is similar to the existing concentration detection device and does not have a cleaning function for the detection cylinder. This requires manual or other cleaning devices to clean it before the next round of detection. The steps are cumbersome and troublesome, and it is easy to delay the time of the detection work. Therefore, an ammonia water concentration detection device and a method thereof are proposed to solve the above problems. Summary of the Invention

[0066] Pour the ammonia water to be tested into the test cylinder 34, and place the test cylinder 34 on the concentration meter 1, and operate the concentration meter 1 to perform the ammonia water concentration test task;

[0067] S3, cleaning of detection tube 34

The first connecting rod 37 drives the first clamping plate 35 to move until the test cylinder 34 is clamped by the first clamping plate 35 and the second clamping plate 36. The frame plate 33 is pushed until the test cylinder 34 is directly below the housing 391 for cleaning.

[0071] During cleaning, first, the third electric push rod 365 works to pull the L-shaped plate 392 downward, and the L-shaped plate 392 drives the shell 391 to move downward until the top of the detection cylinder 34 at the bottom is inside the shell 391, so as to avoid water splashing out of the outside during cleaning. Then, the first electric push rod 396 works to push the U-shaped plate 395 downward, and the U-shaped plate 395 drives the mounting plate 394 to move, and the mounting plate 394 drives the round rod 373 to move, and the round rod 373 drives the connecting frame 393 to move, and the connecting frame 393 drives After the hollow rod 397 is inserted into the detection cylinder 34, the first motor 386 works and drives the first gear 387 to rotate, the first gear 387 drives the second gear 388 to rotate, and the second gear 388 drives the hollow rod 397 to rotate. The side brushes 398 and the bottom brushes 399 on the hollow rod 397 can fully brush the inside of the detection cylinder 34. At the same time, the water pump 362 works to extract the water inside the clean water storage chamber 378 and discharge it into the detection cylinder 34 through the drain port 374 on the hollow rod 397. The combination of the flow impact can properly achieve the purpose of brushing and improve the cleaning quality. After a single brushing is completed, the above similar steps are repeated to control the hollow rod 397 to rise above the detection cylinder 34. The second motor 358 works and drives the threaded control rod 355 to rotate. The threaded control rod 355 drives the external control block 356 to move left and right. The control block 356 drives the lever 357 to move. The lever 357 pushes the control plate 352 behind the detection cylinder 34. This control plate 352 moves and drives the second rack 353 to move. The second rack 353 drives the fourth gear 354 below to rotate. The fourth gear 354 drives the connected second connecting rod 38 to rotate. The second connecting rod 38 drives the second clamping plate 36 to rotate. The second clamping plate 36 drives the detection cylinder 34 to rotate until the opening faces downward, so that the residual water in the detection cylinder 34 can be poured out. When the pouring action is completed, due to the elastic force of the spring, the control plate 352 can be controlled to move to the initial position. Through the above steps, it can be seen that the detection cylinder 34 finally returns to the state of opening facing upward.

[0072] When the cleaning work is completed, the hollow rod 397 is controlled to move into the wider cavity at the upper part of the shell 391, and the second electric push rod 376 works and pushes and pulls the movable plate 371, and the movable plate 371 drives the first rack 372 to move, and the first rack 372 drives the third gear 375 to rotate, and the third gear 375 drives the round rod 373 to rotate, and the round rod 373 drives the connecting frame 393 to rotate until the air guide cover 383 faces directly downward, and the fan 382 and the heating wire 384 work, and the heating wire 384 heats the airflow, so that the hot airflow is blown to the inside of the detection cylinder 34, so as to achieve the purpose of drying the inside of the detection cylinder 34. Accordingly, the detection cylinder 34 is quickly cleaned and dried to ensure that the cleaned detection cylinder 34 can be quickly put into use. After the frame plate 33 is pushed to remove the cleaned detection cylinder 34, the other detection cylinder 34 clamped on the inner side of the frame plate 33 can be kept in the cleaning position, so that when one detection cylinder 34 performs the detection task, the other detection cylinder 34 can be cleaned. After the detection task is completed, the previously cleaned detection cylinder 34 can be taken out for use, so as to perform alternating cleaning and use, thereby avoiding delays in normal detection work due to cleaning operations and ensuring detection efficiency.

[0073] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
