Description

Technical Field

[0001] This utility model relates to the field of detection equipment technology, specifically to a device for detecting the iron ion content in hydroxylamine. Background Technology

[0002] With the continuous development of modern chemical industry, hydroxylamine, as an important chemical raw material, is widely used in many fields such as pharmaceuticals, pesticides, and rubber additives. However, the presence of iron ions in hydroxylamine can significantly affect its performance in various applications. For example, in some chemical reactions, iron ions may act as catalyst impurities, interfering with the reaction process and leading to unstable product quality. In recent years, spectrophotometric iron ion analyzers have been widely used in the field of ion content detection due to their advantages of simple operation and high sensitivity. However, current hydroxylamine iron ion determination equipment is susceptible to problems during the detection process. Factors such as solution homogeneity and interference from external light can affect the accuracy of the results. Furthermore, the detection process requires placing the blank solution and sample solution into the colorimetric cell separately, increasing the workload of operators and reducing efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a device for detecting the iron ion content in hydroxylamine, in order to solve the problems of inaccurate detection and low efficiency of existing hydroxylamine iron ion determination methods mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A device for detecting the iron ion content in hydroxylamine includes an iron ion analyzer that measures iron ions by spectrophotometry, a blank solution colorimetric bottle for zeroing and comparison, and a sample solution colorimetric bottle for holding the hydroxylamine solution. The iron ion analyzer is symmetrically provided with supports with an inverted L-shaped cross-section on both sides, and a lifting cylinder is installed on the top of each set of supports.

[0006] The top surface of the iron ion analyzer is symmetrically provided with two colorimetric measuring cells corresponding to two sets of supports. The colorimetric measuring cells are adapted to the size of the colorimetric bottles and the two are plugged in to fit together.

[0030] A device for detecting the iron ion content in hydroxylamine, such as... Figures 1-3As shown, the device includes an iron ion analyzer 10 that measures iron ions using spectrophotometry, a blank solution colorimetric bottle 20 for zeroing and comparison, and a sample solution colorimetric bottle 30 for holding hydroxylamine solution. The iron ion analyzer 10 has symmetrically arranged supports 40 with inverted L-shaped cross-sections on both sides, and a lifting cylinder 50 is installed on the top of each support 40. The top surface of the iron ion analyzer 10 has symmetrically arranged colorimetric measuring grooves 12 corresponding to the two sets of supports 40. The colorimetric measuring grooves 12 are adapted to the size of the colorimetric bottles and are inserted into each other. The piston rods 51 of the two sets of lifting cylinders 50 are coaxially arranged with the blank solution colorimetric bottle 20 and the sample solution colorimetric bottle 30, respectively. A motor 53 is embedded in the center of the bottom of each set of piston rods 51, and the output shaft of the motor 53 is connected to a stirring shaft 52. Through the iron ion analyzer 10, the iron ion content in hydroxylamine can be accurately measured using spectrophotometry. Blank solution cuvette 20 is used for zeroing and comparison, while sample solution cuvette 30 is used to hold hydroxylamine solution, providing a reliable reference for measurement. Inverted L-shaped supports 40 are symmetrically arranged on both sides of the iron ion analyzer 10, providing stable support for the lifting cylinder 50. The lifting cylinder 50 can drive the piston rod 51 and its embedded motor 53 and connected stirring shaft 52 to rise and fall, facilitating the placement and removal of the blank solution cuvette 20 and sample solution cuvette 30 into or out of the colorimetric measuring cell 12. It also allows the stirring mechanism to be lowered before measurement to stir the solution, ensuring uniformity.

[0031] Furthermore, the top surface of the iron ion analyzer 10 is equipped with a display screen 11 for displaying detection data, so that the detected iron ion content data can be presented intuitively, making it convenient for operators to read and record the data.

[0032] The blank solution colorimetric bottle 20 and the sample solution colorimetric bottle 30 are equipped with graduation lines 21 on their outer walls, which allows for accurate control of the solution volume when filling the bottle, ensuring the consistency and accuracy of the solution volume during the measurement process.

[0033] Specifically, a sealing cap 54 for sealing the mouth of the colorimetric bottle is also installed on the outer wall of the piston rod 51 to prevent leakage during stirring.

[0034] It is worth noting that the diameter of the stirring shaft 52 is smaller than the opening diameter of the colorimetric bottle, which allows the stirring shaft 52 to be smoothly inserted into the colorimetric bottle to stir the solution, while avoiding the inability to insert the colorimetric bottle or damage due to the stirring shaft being too large.

[0035] In addition, it includes two sets of light-shielding covers 60 for shielding the light during testing. The light-shielding covers 60 have a U-shaped cross section and are made of black light shields with a thickness of 2-5mm, which can effectively block external light interference during testing, reduce errors, and improve the accuracy of spectrophotometric measurements.

[0036] The working principle of the device for detecting iron ion content in hydroxylamine:

[0037] First, prepare the blank solution and the sample solution. Add the blank solution to the blank solution cuvette 20 and the sample solution to the sample solution cuvette 30. Use the graduation line 21 on the outer wall of the cuvette to control the volume of the added solution and ensure accuracy.

[0038] Next, add appropriate amounts of hydroxylamine hydrochloride solution and o-phenanthroline solution to the two colorimetric bottles respectively; hydroxylamine hydrochloride is used to reduce ferric ions to ferrous ions, while o-phenanthroline forms a stable colored complex with ferrous ions, which facilitates subsequent detection.

[0039] Then, operate the lifting cylinder 50 to lower the piston rod 51 and allow the stirring shaft 52 to extend into the colorimetric bottle; at this time, the sealing cap 54 on the outer wall of the piston rod 51 can seal the mouth of the colorimetric bottle to prevent the solution from splashing out; turn on the motor 53 embedded in the center of the bottom of the piston rod 51 to drive the stirring shaft 52 to stir the internal solution and make the solution fully mixed and reacted.

[0040] After stirring, operate the lifting cylinder 50 again to raise the stirring shaft 52 from the colorimetric bottle; then, insert the blank solution colorimetric bottle 20 and the sample solution colorimetric bottle 30 into the colorimetric measuring grooves 12 on both sides of the top surface of the iron ion analyzer 10, and cover them with the light-shielding cover 60 to block the light; finally, measure the iron ion using the spectrophotometric method with the iron ion analyzer 10, and display the measurement results on the display screen 11.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.

The scope of protection of this utility model is defined by the appended claims and their equivalents.
