Description

Technical Field

[0001] This utility model relates to the field of sulfide detection technology, specifically to an analyzer for detecting sulfides in gas. Background Technology

[0002] Sulfides are binary compounds formed by sulfur and elements with lower electronegativity than sulfur. In nature, sulfides can exist as minerals, such as pyrite (FeS2) and galena (PbS). In environmental science and chemical analysis, sulfides usually refer to soluble sulfides, such as hydrogen sulfide (H2S) and sodium sulfide (Na2S). Sulfides are common pollutants in the environment. To accurately monitor their concentration, assess environmental quality, and understand pollution levels, analyzers are typically used to detect and analyze sulfides in gases. An analyzer is an instrument used to detect and analyze the composition, properties, or characteristics of substances. Depending on the detection target and analytical requirements, analyzers can be of various types, such as chemical analyzers, physical analyzers, spectrometers, and chromatographic analyzers. Among them, chromatographic analyzers achieve separation of substances based on the difference in partition coefficients between the stationary and mobile phases, and then perform quantitative analysis using a detector. Analyzing sulfides using analyzers allows for timely understanding of air pollution levels, facilitating the implementation of appropriate measures to reduce sulfide emissions. This benefits environmental protection and public health. Furthermore, sulfide monitoring data provides a scientific basis for formulating and adjusting environmental protection policies, helping to ensure the policies are targeted and effective.

[0003] In existing technologies, when analyzing sulfides in gases using an analyzer, the sampled gas is typically injected into the chromatographic column of the analyzer through an injection port. The sample is then adsorbed or partitioned by the stationary phase in the column, and the detector detects the separated components, thereby achieving the analysis of sulfides. However, since the gas may contain particulate impurities during collection, these impurities cannot be effectively intercepted during gas injection, allowing them to enter the analyzer along with the gas. This can easily affect the accuracy of the detection and the lifespan of the analyzer. Therefore, to solve the above problems, an analyzer for detecting sulfides in gases is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an analyzer for detecting sulfides in gases, in order to solve the problem mentioned in the background art that when collecting gases, some particulate impurities may be present in the gas, and when the gas is injected, these particulate impurities cannot be effectively intercepted, causing them to enter the analyzer along with the gas, which can easily affect the accuracy of the detection and the service life of the analyzer.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an analyzer for detecting sulfides in gas, comprising a housing, the housing comprising an instrument, an inlet fixedly connected to the top of the instrument, an inlet hose sleeved on the surface of the inlet, a detector mounted on the top of the instrument, a display screen on the surface of the instrument, and a base at the bottom of the instrument.

[0006] The instrument is provided with a filtration mechanism, which includes a filter plate disposed inside the sample inlet. A connecting block is fixedly connected to the surface of the filter plate. An installation groove is provided inside the sample inlet. A movable groove is provided on the inner wall of the installation groove. A first spring is fixedly connected to the inner wall of the movable groove. A locking block is fixedly connected to the surface of the first spring. A locking groove is provided on the inner side of the connecting block.

[0007] Preferably, the connecting blocks are in two sets and fixedly connected to the filter plate, and the mounting grooves are in two sets and opened on the inner side of the sample inlet.

[0008] Preferably, one end of the first spring is fixedly connected to the movable groove, and the other end of the first spring is fixedly connected to the locking block, wherein the locking block is movable inside the movable groove.

[0009] Preferably, the surface of the base is provided with a protective mechanism, the protective mechanism including a first fixing block, the first fixing block being fixedly connected to the upper surface of the base, a fixing rod being fixedly connected to the inner surface of the first fixing block, a moving block being movably connected to the surface of the fixing rod, a moving rod being movably connected to the surface of the moving block, a second fixing block being fixedly connected to the bottom end of the instrument, a second spring being fixedly connected to the surface of the moving block, and a shock absorber being fixedly installed on the upper surface of the base.

[0010] Preferably, the movable blocks are movably connected to the surface of the fixed rod in two sets. One end of the movable rod is movably connected to the movable block via a rotating shaft, and the other end of the movable rod is movably connected to the second fixed block via a rotating shaft.

[0011] Preferably, one end of the second spring is fixedly connected to the first fixed block, the other end of the second spring is fixedly connected to the moving block, and the two ends of the shock absorber are respectively connected to the instrument and the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The filter plate can filter and intercept particulate impurities in the gas, thus preventing them from affecting the accuracy of the test and the service life of the instrument. At the same time, the movement of the locking block in the movable groove, combined with the elasticity of the first spring, allows the locking block to engage and disengage with the groove, thereby fixing and unfixing the connecting block. This facilitates the replacement of the filter plate and ensures the quality and effectiveness of the filter plate in filtering the gas.

[0014] 2. When a collision or shaking occurs, the movable rod moves, allowing the moving block to move on the surface of the fixed rod, and causing the second spring to deform. Through the elastic properties of the second spring and the setting of the shock absorber, the shaking caused by the collision can be mitigated to a certain extent, thereby effectively reducing the transmission of external vibrations to the instrument, ensuring the stable operation of the instrument during the analysis process, and helping to ensure the quality of the analysis.

[0021] 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.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] An analyzer for detecting sulfides in gas includes a housing, which includes an instrument 1. An inlet 11 is fixedly connected to the top of the instrument 1, and an injection hose 12 is fitted onto the surface of the inlet 11. A detector 13 is mounted on the top of the instrument 1, and a display screen 14 is provided on the surface of the instrument 1. A base 15 is provided at the bottom of the instrument 1. A chromatographic column is installed inside the instrument 1. Through the inlet 11 and the injection hose 12, gas can enter the instrument 1 and then the chromatographic column. The gas sample is adsorbed or partitioned by the stationary phase in the chromatographic column. Different components migrate at different speeds in the chromatographic column due to their different properties, thus achieving separation. The separated components enter the detector 13 and are converted into measurable signals. The detection and analysis results can be displayed on the display screen 14.

[0024] The instrument 1 is equipped with a filtration mechanism, which includes a filter plate 2. The filter plate 2 is located inside the sample inlet 11. A connecting block 21 is fixedly connected to the surface of the filter plate 2. An installation groove 22 is provided inside the sample inlet 11. A movable groove 23 is provided on the inner wall of the installation groove 22. A first spring 24 is fixedly connected to the inner wall of the movable groove 23. A locking block 25 is fixedly connected to the surface of the first spring 24. A locking groove 26 is provided on the inner side of the connecting block 21. By setting up the filter plate 2, the gas can be filtered when detecting the gas, and particulate impurities can be intercepted. This can prevent particulate impurities from entering and affecting the service life of the instrument 1 and the accuracy of the analysis.

[0025] Furthermore, the connecting blocks 21 are fixedly connected to the filter plate 2 in two sets, and the mounting grooves 22 are opened in two sets on the inner side of the inlet 11. By setting the connecting blocks 21 and opening the mounting grooves 22, the filter plate 2 can be positioned in the inlet 11, making the installation of the filter plate 2 more convenient and accurate, and thus facilitating the use of the filter plate 2.

[0026] Furthermore, one end of the first spring 24 is fixedly connected to the movable groove 23, and the other end of the first spring 24 is fixedly connected to the locking block 25. The locking block 25 is movable inside the movable groove 23. The setting of the first spring 24 can reset the locking block 25, thereby enabling the locking block 25 and the locking groove 26 to engage, which facilitates the fixing of the filter plate 2 in the sample inlet 11. The separation of the locking block 25 and the locking groove 26 also facilitates the removal and replacement of the filter plate 2, ensuring the filtration effect of the filter plate 2 on particulate impurities.

[0027] Furthermore, a protective mechanism is provided on the surface of the base 15. The protective mechanism includes a first fixed block 3, which is fixedly connected to the upper surface of the base 15. A fixed rod 31 is fixedly connected to the inner surface of the first fixed block 3. A movable block 32 is movably connected to the surface of the fixed rod 31. A movable rod 33 is movably connected to the surface of the movable block 32. A second fixed block 34 is fixedly connected to the bottom of the instrument 1. A second spring 35 is fixedly connected to the surface of the movable block 32. A shock absorber 36 is fixedly installed on the upper surface of the base 15. When a collision or shaking occurs, the movable rod 33 can stably support the instrument 1 through the cooperation of the second spring 35 and the shock absorber 36, thereby effectively reducing the transmission of external vibrations to the instrument 1 and ensuring the accuracy of the instrument 1 in sulfide analysis.

[0028] Furthermore, the movable block 32 is movably connected to the surface of the fixed rod 31 in two sets. One end of the movable rod 33 is movably connected to the movable block 32 via a rotating shaft, and the other end of the movable rod 33 is movably connected to the second fixed block 34 via a rotating shaft. The movable rod 33 can support the instrument 1, so that when a collision or shaking occurs, the movable block 32 will move on the surface of the fixed rod 31, and the movable rod 33 can move, thereby causing the second spring 35 to deform.

[0029] Furthermore, one end of the second spring 35 is fixedly connected to the first fixed block 3, and the other end of the second spring 35 is fixedly connected to the moving block 32. The two ends of the shock absorber 36 are respectively connected to the instrument 1 and the base 15. Through the elastic properties of the second spring 35, combined with the setting of the shock absorber 36, when the instrument 1 is placed on a table or platform, external collisions are not likely to affect the instrument 1, which is conducive to ensuring the stable operation of the instrument 1.

[0030] Working principle: In use, the filter plate 2 can intercept particulate impurities in the gas. When the filter plate 2 needs to be replaced, pull out the sample inlet hose 12 to separate it from the surface of the sample inlet 11. Then, pry open the connecting block 21. The locking block 25 will move inward into the movable groove 23 under force. At this time, the first spring 24 is in a contracted state, realizing the separation of the locking block 25 and the locking groove 26. Then, the connecting block 21 can be separated from the mounting groove 22, and the filter plate 2 can be taken out from the sample inlet 11 for replacement. When it is necessary to fix the replacement filter plate 2, make the connecting block 21... When the connecting block 21 enters the mounting groove 22, the locking block 25 and the surface of the connecting block 21 come into contact, and the locking block 25 will be squeezed by the connecting block 21, so that the locking block 25 moves inward to the movable groove 23. At this time, the first spring 24 is in a contracted state. When the connecting block 21 moves down, the locking block 25 and the slot 26 are opposite each other, so that the locking block 25 can be reset under the rebound action of the first spring 24, and then the locking block 25 and the slot 26 can be engaged, so that the connecting block 21 can be fixed, thereby completing the installation of the filter plate 2. Then the sample inlet tube 12 can be put on the sample inlet 11.

[0031] When an external collision or shaking occurs, the movable rod 33 moves through the rotating shaft, allowing the movable block 32 to move on the surface of the fixed rod 31. At this time, the second spring 35 deforms, and with the addition of the shock absorber 36, the vibration caused by the collision or shaking can be mitigated to a certain extent, thereby reducing the impact on the instrument 1.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
