Technical Field

[0001] The utility model relates to the technical field of medical waste detection, in particular to a device for detecting ammonia nitrogen in wastewater in medical waste. Background Art

[0002] Ammonia nitrogen refers to nitrogen that exists in the form of free ammonia and ammonium ions in water. It is a commonly used indicator in water quality testing and is used to evaluate the degree of nitrogen pollution in water bodies. When the concentration of ammonia nitrogen in water is too high, it will have toxic effects on aquatic organisms and cause damage to the ecological environment of the water body. When the ammonia nitrogen in the water body reaches a certain concentration, it will release ammonia gas, causing harm to the environment and human health.

The ammonia nitrogen detection device for wastewater in medical waste in the utility model patent is provided with a feed box with a filter unit in front of the main body. The wastewater is filtered to remove solid impurities in the feed box before entering the main body, thereby eliminating the influence of solid impurities on the detection result; a stirring component and a detection component are added in the main body. The stirring component stirs the wastewater all the time to ensure that the ammonia nitrogen content in the wastewater is uniform, and the detection component includes a plurality of roots distributed in Sampling needles at different places in the main body are used to sample wastewater at different positions, so as to facilitate comparison of test results, and the test results are more comprehensive and accurate.

[0023] Specifically, Figure 2 As shown, after the medical waste is separated into waste liquid through the filter plate 407, the filter plate 407 together with the solid waste on the filter plate 407 can be taken out by opening the door of the filter box 406, so that they can be processed separately.

[0024] Specifically, Figure 1 As shown, the detector body 3 first uses the internal sampling unit to draw the waste liquid into the detector body 3 through the sampling tube 405, and then converts the ammonia nitrogen in the waste liquid into ammonium ions through the digestion reactor to prepare for subsequent measurements. Then, the light source, cuvette and photodetector in the optical system measure the change in the light signal of the waste liquid after the chemical reaction, and then the circuit board is responsible for processing the electrical signal output by the optical system, and the ammonia nitrogen content is calculated and displayed on the screen.

[0025] Specifically, Figure 2 As shown, if the ammonia nitrogen in the waste liquid is not diluted and discharged directly, it will bring a series of serious hazards. The presence of ammonia nitrogen wastewater will increase the difficulty of operating the tap water treatment plant, may cause odor in drinking water, and affect people's daily life. Ammonia nitrogen will promote the reproduction of microorganisms in water pipes and water-using equipment, forming bioscaling, which will not only block pipes and water-using equipment, affecting the efficiency and life of the equipment, but also ammonia nitrogen is corrosive to certain metals, posing a threat to the safe operation of equipment and pipelines.

[0026] When implementing, follow these steps:

[0028] 2) Then, the motor 401 is turned on to drive the stirring rod 402 to mix and stir the waste liquid in the treatment box 2;

[0029] 3) The cylinder 403 then drives the movable plate 404 and the sampling tube 405 to move downward, and then the sample is extracted through the detector body 3;

[0030] 4) Finally, a suitable volume of diluent is introduced into the transparent quantitative box 408 according to the data, and then the diluent and waste liquid are fully mixed and diluted by the stirring rod 402.

[0031] In summary, the ammonia nitrogen detection device for wastewater in medical waste pours the medical waste into the filter box 406 through the feed pipe for solid-liquid separation, and the liquid in the medical waste reaches the treatment box 2 through the discharge pipe, and then the motor 401 is turned on to drive the stirring rod 402 to stir the waste liquid in the treatment box 2, and then the cylinder 403 is turned on to drive the moving plate 404 to move downward, and then the moving plate 404 drives the sampling tube 405 to move, and then the detector body 3 is opened to extract the waste liquid through the sampling tube 405 for detection. After the detection is completed, according to The data detected by the detector body 3 is poured into the diluent guide tube 409, and the volume of the diluent is observed through the scale on the transparent quantitative box 408 and the buoyancy plate 410. After reaching the appropriate volume, the first valve is opened to discharge the diluent into the treatment box 2, and then the motor 401 drives the stirring rod 402 to stir the waste liquid and the diluent, thereby diluting the ammonia nitrogen in the waste liquid. After completion, the diluted waste liquid can be discharged, so as to achieve the purpose of extracting samples at different positions and diluting the ammonia nitrogen in the internal waste liquid after the detection is completed.
