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-combustible 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 dangerous to combustion and explosion.

[0003] Patent network announcement number CN219978248U discloses a device for rapid detection of ammonia concentration, including an ammonia concentration detector, a No. 1 connection block is fixedly connected to the rear right end of the ammonia concentration detector, a No. 1 connection block is fixedly connected to the end away from the ammonia concentration detector with a placement mechanism, a detection cylinder is connected to the placement mechanism, a No. 2 connection block is fixedly connected to the middle of the left end and the middle of the right end of the ammonia concentration detector, and the two No. 2 connection blocks are fixedly connected to the ends away from the ammonia concentration detector, and the middle of the upper ends of the two fixed blocks are interspersed with a stabilizing mechanism. The placement mechanism is set up to facilitate the placement of the detection cylinder, and when the detection cylinder is needed to hold ammonia for detection, it is convenient to take it, avoiding the adverse consequences of taking the wrong detection cylinder 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 next round of detection values, it is often necessary to clean the detection cylinder before performing the next step. 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.

The concentration measuring instrument is an existing structure, so its detection principle and detailed structure are not further described here. After the test, the ammonia water in the test tube 34 is poured out, and then the test tube 34 can be temporarily placed on the support plate 366 at the bottom of the frame plate 33. When the test tube 34 needs to be cleaned, the threaded adjustment rod 369 in front of the test tube 34 is rotated, and the threaded adjustment rod 369 drives the movable plate 368 to move, and the first connecting rod 37 connected to the movable plate 368 moves, and the first connecting rod 37 drives the first clamping plate 35 to move until the test tube 34 is clamped by the first clamping plate 35 and the second clamping plate 36, and the frame plate 33 is pushed until the test tube 34 is directly below the shell 391 for cleaning;

[0071] During specific 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 tube 34, the first motor 386 starts to work 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 tube 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 tube 34 through the drain port 374 on the hollow rod 397. The flow impact is matched, and the purpose of brushing can be properly achieved, and the cleaning quality is improved. After a single brushing is completed, the above similar steps are repeated to control the hollow rod 397 to rise above the detection tube 34, and the second motor 358 works and drives the threaded control rod 355 to rotate, and the threaded control rod 355 drives the external control block 356 to move left and right, and the control block 356 drives the lever 357 to move, and the lever 357 pushes the control plate 352 behind the detection tube 34, and the control plate 352 moves and drives the second rack 353 to move, and the second rack 353 drives the fourth gear 354 below to rotate, and the fourth gear 354 drives the connected second connecting rod 38 to rotate, and the second connecting rod 38 drives the second clamping plate 36 to rotate, and the second clamping plate 36 drives the detection tube 34 to rotate until the opening faces downward, and the residual water in the detection tube 34 can be poured out. When the dumping action is completed, due to the elastic force of the spring, the control plate 352 can be controlled to move to the initial position. It can be seen from the above steps that the detection tube 34 finally returns to the state of opening 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 tube 34, so as to achieve the purpose of drying the inside of the detection tube 34. Accordingly, the detection cylinder 34 is quickly cleaned and dried to ensure that the cleaned detection cylinder 34 can be quickly reused. 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 of the detection cylinders 34 performs the detection task, the other detection cylinder 34 can be cleaned. After the detection task is completed, the last 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 protection scope 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 protection scope of the present invention.
