Description

Technical Field

[0001] The invention relates to the technical field of electrolytic cells, and in particular to an electrolytic cell used for separating oxide inclusions in steel. Background Art

[0002] In the broad field of chemical analysis, especially in the sub-direction of metallurgical chemical analysis, electrolysis occupies a vital position. It is one of the key means to separate samples and purify the effective components in samples. In the quantitative chemical analysis process involved in electrochemical reactions, there are many issues that need to be paid attention to. Among them, the contamination of samples by air due to the long electrolytic reaction time is a hidden danger that cannot be ignored. Air pollution may introduce impurities and interfere with the accuracy of the analysis results. At the same time, the effect of acidity on the electrolytic reaction is also very significant. As the electrolytic reaction proceeds, the acidity of the solution may change, and this change may affect the rate and direction of the reaction. Therefore, in order to ensure that the electrolytic reaction can proceed smoothly, the acidity must be adjusted at any time according to the degree of the reaction. This electrolytic cell needs to have two key functions. One is to be able to effectively isolate the air and prevent the sample from being contaminated during the electrolysis process, thereby ensuring the accuracy of the analysis results; the second is to have an acidity adjustment function so that the acidity can be flexibly adjusted according to the actual situation of the reaction, creating a suitable environment for the electrolytic reaction, and then ensuring that the electrolytic reaction can proceed efficiently and stably. For these reasons, it is urgent to design a special electrolytic cell. Summary of the invention

[0008] Furthermore, the electrolytic cell is provided with an electrolyte discharge port and a drain port for releasing and adding electrolyte, and has a pH value detection function.

[0009] Furthermore, a magnetic stirrer is installed in the groove at the bottom of the electrolytic cell to stir the electrolyte, accelerate the flow of the electrolyte, and promote the electrolytic reaction speed.

[0010] Furthermore, the cathode of the electrolytic cell adopts a hollow thick copper ring, the surface area of ​​the copper ring is 10-50 times the surface area of ​​the sample, and the cathode electrode of the copper ring is provided with an electrolyte flow hole.

[0011] Furthermore, the impurity-carrying capsule is made of collodion, and has the characteristics of being permeable to ions and water in the electrolyte but impermeable to oxidized impurity precipitation.

[0012] Furthermore, the debris carrying capsule is equipped with a bracket made of polytetrafluoroethylene, which is integrally cast and has a stable structure and is corrosion-resistant.

[0013] Furthermore, the electrolytic cell cover carries an electrolysis sample rack, an electrolyte replenisher, a reverse exhaust valve, and a pH value regulator.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0029] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0030] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0031] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0032] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0033] like Figures 1 to 3As shown, the present invention provides an electrolytic cell for separating oxide inclusions in steel, comprising: an electrolytic cell body 1, an electrolytic cell cover 11, a copper ring 7, an impurity carrying capsule 6, and a desktop heating magnetic stirring rack;

The electrolytic sample is fixedly suspended above the oxidized inclusions carrying capsule 6 after the sample is electrolyzed through the electrolytic sample hanger 15. The electrolytic sample is connected to the wire through the sample wire inlet 16. The sample inlet is sealed with acid-resistant, high-temperature-resistant and elastic rubber, and only the wire connected to the electrolytic sample is allowed to pass.

A heating coil 30 and a magnetic stirrer 32 are provided in the groove 31 inside the desktop heating magnetic stirring carriage. When power is turned on, the magnetic stirring bar 5 in the electrolytic cell is driven to rotate, further promoting the flow of the electrolyte and the progress of the electrolytic reaction.
