Description

Technical Field

[0001] The utility model belongs to the technical field of elemental analysis, and particularly relates to a reduction copper loading device based on an elemental analyzer. Background Technique

[0002] When analyzing solid samples with the existing instrument German Element (variomacrocube), the content of nitrogen elements in soil is mainly detected based on a non-dispersive infrared detector (NDIR). The specific operation is as follows:

[0003] First, the weighed sample is placed in tin foil, squeezed into a sheet, put into the instrument injection tray, and pushed into the heating chamber for nitrogen determination. After the sample is burned at high temperature, nitrogen dioxide is generated. The nitrogen dioxide enters the reduction tube and is reduced to nitrogen by copper. The nitrogen enters the detector for content determination.

[0004] After detecting about 100 samples, the copper in the reduction tube is oxidized, and the reduction power is insufficient, so subsequent determination cannot be carried out and needs to be replaced. Existing problems: The copper particles filled in the reduction tube are easily aggregated and caked after being burned and reduced at high temperature. Since 4 sections of reduction copper are filled, under the action of gravity, it is very difficult to take out the reduced copper plate at the bottom after caking. A special tool is randomly equipped, and it usually takes 1 to 2 hours or even longer to complete the replacement. When detecting a large number of samples, it needs to be replaced once every 2 days, seriously affecting work efficiency. When taking out the copper oxide carelessly, the reduction tube is easily broken, and the broken quartz reduction tube is extremely likely to cause harm to the detector; the purchase cost of a reduction tube is 2000 yuan, resulting in economic losses and affecting the efficiency of detection and analysis.

[0005] Through the above analysis, the problems and defects of the existing technology are as follows:

[0006] 1) The copper particles filled in the reduction tube are easily aggregated and caked after being burned and reduced at high temperature.

A special tool is randomly equipped, and it usually takes 1 to 2 hours or even longer to complete the replacement. When detecting a large number of samples, it needs to be replaced once every 2 days, seriously affecting work efficiency.

[0007] 2) When taking out the copper oxide carelessly, the reduction tube is easily broken, and the broken quartz reduction tube is extremely likely to cause harm to the detector; the purchase cost of a reduction tube is 2000 yuan, resulting in economic losses and affecting the efficiency of detection and analysis.

When it is necessary to replace the reduced copper, only the loading device needs to be poured out and new reduced copper pellets are refilled, and it can be recycled.

[0016] The novel loading device designed by the present utility model can be quickly and easily combined into a cylinder through size control, facilitating the loading of reduced copper pellets; especially for the replacement of reduced copper pellets, only by pouring out the loading device can the caked waste copper pellets be taken out, greatly reducing the time and workload of manual drilling, improving the efficiency of analysis and testing, and avoiding the risk of breaking the reduction tube; the porous design at the bottom of the loading device has the same ventilation effect as before, ensuring that all gases pass through the copper pellets and are reduced, guaranteeing the accuracy of the results.

[0017] Second, compared with the prior art, the reduction copper loading device based on an elemental analyzer provided by the present utility model mainly solves the following technical problems and achieves remarkable technical progress:

[0018] 1. Improve the reduction efficiency: Through reasonable loading design, such as the combined use of porous bottoms, corundum balls and quartz wool, the reduced copper pellets can more fully contact the reaction gas during the reaction process, thereby improving the reduction efficiency.

[0019] 2. Optimize the reaction environment: The use of corundum balls and quartz wool can stabilize the reaction environment, reduce heat loss, enabling the reaction to proceed at a more stable and uniform temperature, which helps improve the reliability and consistency of the reaction.

[0036] The quartz liner 1 is provided with a bottom with pores 2; the inner bottom of the quartz liner 1 is filled with corundum balls 4; reduction copper particles 5 are filled above the corundum balls 4.

[0037] Quartz wool 6 is filled above the reduction copper particles 5 provided by an embodiment of the present utility model;

[0038] Corundum balls 4 are filled above the quartz liner 1 provided by an embodiment of the present utility model;

[0039] Silver wire 3 is filled at the inner top of the quartz liner 1 provided by an embodiment of the present utility model.

[0040] The present utility model adopts the following technical solutions:

[0041] First, loading of reduction copper particles:

[0042] ① According to the instrument operation instructions, fill the reduction tube with fillers such as quartz wool 6 and corundum balls 4, combine two reduction copper loading devices into a complete cylinder, load it into the reduction tube, fill it with copper particles, load 2 mm more, load 5 mm of quartz wool 6, repeat the above steps until 4 reduction copper loading devices are loaded, and then load corundum balls and silver wire according to the operation instructions to complete the filling of the quartz tube.

[0043] Second, replacement of the waste reduced copper pellets 5

[0044] When the reduced copper is exhausted, the silver wire 3, corundum balls 4, reduced copper filling device, and quartz wool 6 are poured out in sequence. The utility model automatically divides into two halves, and the caked waste copper pellets can be taken out. Re-packing can be carried out according to the above steps.

[0045] A reduced copper filling device based on an elemental analyzer provided by an embodiment of the utility model uses components such as a quartz liner tube, a porous bottom, silver wire, corundum balls, reduced copper pellets, and quartz wool to construct a dedicated chemical reaction environment, aiming to provide high-purity reduced copper for the analyzer to improve the accuracy and reliability of the analysis results.

[0046] Component composition and functions:

[0047] Quartz liner tube 1: As the main structure of the device, it provides a closed reaction space. The quartz material has high temperature resistance, chemical stability, and can resist most chemical corrosion, making it suitable for chemical reactions at high temperatures.

[0048] Porous bottom 2: Set at the bottom of the quartz liner tube, it allows gases or other small molecule substances to pass through, but blocks larger solid particles, helping to maintain the stability of the internal environment.

[0049] Corundum balls 4: Filled at the bottom and top of the quartz liner tube, the corundum balls have a high melting point and high chemical stability, can be used as a support material, and help disperse heat during the reaction process to prevent local overheating.

[0050] Reduced copper pellets 5: The main reaction material, used to absorb and reduce oxides in the sample during elemental analysis, and reduce the oxides through chemical reactions to improve the accuracy of the analysis.

[0051] Quartz wool 6:

[0052] Filled above the reduced copper pellets, as a filling material, the quartz wool can prevent the reduced copper pellets from being carried out of the liner tube by the gas flow during the heating process, and at the same time has good thermal stability and chemical inertness.

[0053] Silver wire 3: Filled at the top, the silver wire can be used as a medium for electrical conduction and heat conduction, helping to maintain the temperature balance of the entire system and improve the reaction efficiency.

[0054] Working principle: When the device starts to work, the gas introduced through the bottom pores (such as hydrogen) will flow upward from the bottom. The gas first passes through the corundum ball layer at the bottom. The corundum balls can help the gas distribute evenly and, at the same time, act as a heat dispersion layer to reduce hot spots and improve the thermal efficiency of the system. Then, the gas flows through the reduced copper granule layer. In this layer, the reduced copper granules will react with the oxygen in the gas, thereby capturing and reducing oxides. Especially when performing elemental analysis, it reduces the oxides in the sample and improves the purity and accuracy of the analysis. The quartz wool layer not only prevents the reduced copper granules from being carried away by the gas flow but also helps maintain the temperature and chemical stability of the entire reaction chamber. Finally, the gas passes through the corundum ball layer and silver wire layer at the top, and these components further help balance the gas temperature and maintain the stability of the chemical environment.

[0055] Through this structure and material selection, the device can carry out chemical reactions efficiently and stably, providing ideal test conditions for the elemental analyzer, thereby improving the accuracy and reliability of the analysis. This design is also easy to maintain and replace reaction materials, making it suitable for long-term and repeated use.

[0056] Some positive effects have been achieved during the research and development or use of the embodiments of the present utility model. Compared with the prior art, it indeed has great advantages. The following content will be described in combination with the data, charts, etc. of the test process.

[0059] Embodiment 1: A reduced copper loading device based on an elemental analyzer. When implemented, it uses a quartz liner tube. The bottom of the quartz liner tube is designed with multiple small holes to facilitate gas flow. First, a layer of corundum balls is filled at the bottom of the quartz liner tube to ensure uniform gas distribution, and reduced copper granules are tightly filled above the corundum balls. To ensure that the reduced copper granules will not be blown away during gas flow, a layer of quartz wool is provided above the copper granules for fixation. In addition, a layer of corundum balls is filled again above the inner part of the quartz liner tube to further stabilize the gas flow, and silver wires are arranged at the inner top of the quartz liner tube to enhance the electrical conductivity and heat conductivity of the device.

[0060] Example 2: In this example, we use a quartz liner of specific dimensions with fine holes machined at the bottom to optimize the efficiency of gas passage. In the internal structure, a layer of fine corundum balls is laid at the bottom to support and evenly distribute the incoming gas. Tightly arranged above them are reduced copper grains, which have high reduction performance and can effectively remove oxygen in the gas. To prevent the reduced copper grains from shifting during gas flow, a layer of compacted quartz wool is provided above. In addition, a layer of corundum balls is added again in the area close to the top of the quartz liner to further balance the gas flow, and silver wires are added at the very top to enhance the performance of the entire device by utilizing the excellent electrical conductivity and thermal stability of silver.
