Description

Technical Field

[0001] This utility model relates to the field of chemical testing equipment technology, and in particular to a device for testing sulfate ions in fluorosilicic acid. Background Technology

[0002] As an important chemical raw material, the purity of fluorosilicate, especially the content of sulfate impurities, is one of the key indicators for measuring its quality. In conventional chemical analysis methods, in order to accurately determine the content of sulfate ions, it is usually necessary to first eliminate the large number of fluorosilicate ions present in the sample that will interfere with subsequent detection. An effective method is to add potassium salt, so that the fluorosilicate ions react with potassium ions to form potassium fluorosilicate precipitate with low solubility, and then separate the precipitate from the test solution by filtration.

[0003] In practice, it has been found that the solubility of potassium fluorosilicate is closely related to temperature. Its solubility decreases significantly at low temperatures. To ensure a more complete precipitation reaction and minimize the interference of fluorosilicate ions, the entire precipitation and filtration process needs to be carried out in a stable low-temperature environment. Existing laboratory operations are usually intermittent and fragmented. After mixing the samples, operators place them in a refrigerator or ice bath for cooling and precipitation. Once precipitation is complete, the samples are transferred to a laboratory bench at room temperature for filtration. During this transfer and filtration process, the samples and equipment inevitably exchange heat with the surrounding room-temperature air, causing the sample temperature to rise. Some of the already formed potassium fluorosilicate precipitate may redissolve, resulting in incomplete removal of interfering ions and directly affecting the accuracy and stability of the final test results. Current technology lacks a dedicated device that can integrate the maintenance of a low-temperature environment with the operation of key experimental steps, making the testing process not only cumbersome but also inefficient.

[0004] Therefore, this invention proposes a device for testing sulfate ions in fluorosilicic acid to overcome the shortcomings of existing technologies. Utility Model Content

[0005] In view of the problems in the existing technology of testing sulfate in fluorosilicic acid, such as the lack of an integrated low-temperature constant temperature environment and convenient operating platform, the testing process is scattered, the temperature control is inaccurate, and errors are easily introduced. This utility model aims to provide a device for testing sulfate in fluorosilicic acid with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a device for testing sulfate ions in fluorosilicic acid, including an operating box and a box cover hinged to the top of the operating box. A constant temperature mechanism and a storage mechanism are integrated inside the operating box.

[0007] The temperature control mechanism includes a cooling coil fixedly connected to the inner left wall of the control box, a cold coil fixedly connected to the bottom of the control box, a base plate covering the cold coil, a temperature sensor embedded inside the control box, and an adjustment panel integrated on the outside of the control box. The storage mechanism is set up based on the base plate, and includes a storage slot and an operating platform on the top surface of the base plate.

[0008] The cooling coil and the cooling coil form a heat exchange connection to achieve effective heat transfer and uniform distribution of cold energy over a large area at the bottom of the chamber. Furthermore, the temperature sensor and the adjustment panel are electrically connected to the cooling coil, together forming a closed-loop temperature control system that can monitor the temperature in real time and automatically adjust the cooling power. This transforms the entire internal space of the operating chamber into a precise low-temperature constant-temperature environment. The storage slots and operating platform of the storage mechanism are directly set on the base plate cooled by the constant-temperature mechanism, achieving an organic combination of low-temperature environment and experimental operation.

[0009] Preferably, the constant temperature mechanism further includes a partition, an insulation plate, and heat dissipation holes. The partition is fixedly disposed between the cooling element and the storage mechanism to achieve physical isolation between the cooling source and the operating area, and to guide the cold air to circulate reasonably within the box. The insulation plate is closely attached to the inner wall of the operating box to enhance the overall thermal insulation performance and reduce cold loss. The heat dissipation holes are opened on the outer side wall of the operating box corresponding to the hot end of the cooling element to ensure that the heat generated by the cooling element can be dissipated in time and maintain its efficient cooling performance.

[0010] Preferably, the base plate is made of soft sponge material, which not only covers and smooths the uneven cold coils below, providing a flat base for the storage mechanism, but also cushions and protects the placed glass instruments, preventing damage due to temperature differences or impacts. The operating platform is specifically positioned on the base plate in the area directly corresponding to the cold coils. This layout allows the operating platform to achieve the most direct and efficient cooling effect, which is beneficial for conducting key precipitation and filtration experimental steps under sufficiently low temperature conditions.

[0011] Preferably, the storage compartment includes at least two different sized openings, specifically a smaller radius storage compartment and a larger radius storage compartment, to accommodate the classification and storage needs of experimental equipment of different sizes and shapes, ensuring an orderly layout within the box. The inner diameter and depth of the smaller radius storage compartment are specially designed to stably accommodate and limit commonly used reagent bottles, effectively preventing them from tipping over during operation. The inner diameter and depth of the larger radius storage compartment are specially designed to accommodate larger filter bottles and jacketed funnels, ensuring stable placement of the filtration device in low-temperature environments. The temperature sensor is configured to continuously monitor the internal temperature of the operating box and send the temperature signal to the adjustment panel. The adjustment panel, based on the difference between the received temperature signal and the preset temperature, automatically adjusts the cooling power of the cooling element through internal control logic, thereby achieving precise dynamic control of the internal temperature and ensuring a constant experimental environment.

[0012] This utility model has the following beneficial effects: 1. This utility model solves the problems in the prior art where the testing process is scattered, requires travel between the refrigeration equipment and the operating table, and the unstable ambient temperature easily leads to incomplete precipitation and interference with subsequent tests by integrating a constant temperature mechanism and a storage mechanism inside the operating box and utilizing the coordinated work of the cooling coil, cold coil, temperature sensor and adjustment panel. It achieves the technical effect of centralizing the experimental process, providing a stable low temperature environment, and thus significantly improving the accuracy and reliability of the test results.

[0013] 2. This utility model solves the problems of chaotic storage, inconvenient access, and lack of stable low-temperature operating areas for experimental instruments and reagents in the prior art by setting a base plate covering the cold coil and opening storage slots of different sizes and a dedicated operating platform on the base plate. It achieves the technical effect of orderly and customized low-temperature storage of experimental items and provides an efficient cooling platform for key filtration steps, thereby improving the convenience and safety of experimental operations.

[0014] 3. This utility model solves the problems of existing technologies that rely on multiple independent equipment combinations, occupy a large space, consume a lot of energy, and have complicated operating procedures by highly integrating refrigeration, heat preservation, temperature control, storage and operation functions into an integrated operating box. It achieves the technical effect of compact equipment structure, comprehensive functions, reduced energy consumption and easy standardization, and provides a dedicated and efficient integrated solution for chemical testing.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] Example: Please refer to Figures 1 to 4 This utility model provides a device for testing sulfate ions in fluorosilicic acid, which aims to solve the problems in the prior art where the lack of an integrated low-temperature constant temperature environment and a convenient operating platform 405 leads to inaccurate temperature control, cumbersome operation, and easy introduction of errors during the testing process.

[0019] like Figure 1 and Figure 2 As shown, an apparatus for testing sulfate ions in fluorosilicic acid includes an operating box 1 and a cover 2 hinged to the top of the operating box 1. The operating box 1 forms the closed main body of the entire apparatus and provides installation space and a sealed environment for the internal functional mechanisms. The cover 2 cooperates with the operating box 1 to close and maintain the temperature stability of the internal space. A constant temperature mechanism 3 and a storage mechanism 4 are integrated inside the operating box 1. The constant temperature mechanism 3 is used to create and maintain a constant low temperature environment for the test experiment, while the storage mechanism 4 is used for centralized and low-temperature storage and operation of the instruments and reagents required for the experiment.

[0020] Please refer to Figure 2 , Figure 3 and Figure 4The constant temperature mechanism 3 includes a cooling element 301 fixedly connected to the inner wall of the left side of the control box 1, a cold coil 302 fixedly connected to the bottom of the control box 1, a base plate 303 covering the cold coil 302, a temperature sensor 307 embedded inside the control box 1, and an adjustment panel 308 integrated outside the control box 1. The cooling element 301, as a cooling component, has its cold end connected to the cold coil 302 for heat exchange, so that the cooling energy generated by the cooling element 301 can be efficiently conducted to the cold coil 302, which is widely distributed at the bottom of the box, thereby rapidly and evenly cooling the internal space of the control box 1. The temperature sensor 307 and the adjustment panel 308 are both electrically connected to the cooling element 301, forming a closed-loop temperature control system. Based on the internal temperature data monitored in real time by the temperature sensor 307, the cooling power of the cooling element 301 can be manually set or automatically adjusted by the adjustment panel 308 to accurately maintain a constant internal temperature.

[0021] The storage mechanism 4 is set up based on the base plate 303. It includes a storage slot 401 integrally formed on the top surface of the base plate 303 and an operating platform 405. The base plate 303 is made of soft sponge material. Its softness can not only perfectly fit and cover the uneven cold coil 302 below to form a flat surface, but also provide cushioning and protection for the glass instruments placed on it. The operating platform 405 is set on the base plate 303 and directly corresponds to the area of ​​the cold coil 302, ensuring that key operations such as filtration performed on the platform can obtain the best low-temperature cooling effect.

[0022] Please refer to Figure 2 The partition 304 is fixedly installed between the cooling chip 301 and the storage mechanism 4 to physically isolate the cooling source from the operating area, avoid direct contact, and guide the circulation of cold air. The insulation plate 305 is closely attached to the inner wall of the operating box 1, covering the inside, so as to minimize the heat exchange between the box and the outside and slow down the internal temperature rise. The heat dissipation hole 306 is opened on the outer side wall of the operating box 1 corresponding to the hot end of the cooling chip 301, so as to dissipate the heat generated by the cooling chip 301 during operation in a timely manner and ensure cooling efficiency.

[0023] To achieve orderly and customized storage of different experimental equipment, the storage tank 401 includes at least two different sizes of openings: a storage tank 401 with a smaller radius and a storage tank 401 with a larger radius. The inner diameter and depth of the storage tank 401 with a smaller radius are designed to stably accommodate and limit commonly used reagent bottles 402 in experiments, preventing them from tipping over or sliding. The inner diameter and depth of the storage tank 401 with a larger radius are designed to accommodate a combination of filter bottles 403 and jacketed funnels 404 with a larger volume, so that the entire device can be stably placed in a low-temperature environment during filtration operations.

[0024] To enhance the intelligence and accuracy of the temperature control system, the temperature sensor 307 is configured to continuously monitor the internal temperature of the operating box 1 and send the collected temperature signal to the adjustment panel 308 in real time. The internal control circuit of the adjustment panel 308 controls the current supplied to the cooling chip 301 through a specific algorithm based on the difference between the received temperature signal and the user preset temperature, thereby accurately adjusting its cooling power and achieving dynamic stability and precise control of the internal temperature.

[0025] Working principle: The experiment to test for sulfate in fluorosilicic acid needs to be conducted in a low-temperature environment to produce precipitation and eliminate other factors. Therefore, a constant temperature mechanism 3 is required to maintain the low temperature. Before the test, the cover 2 inside the operating chamber 1 needs to be opened. A cooling plate 301 is installed on the left side of the operating chamber 1 to facilitate internal temperature exchange. The cooling plate 301 is fixedly connected to the cold coil 302 located at the bottom of the operating chamber 1, continuously absorbing internal heat through the cold coil 302 to maintain the low temperature. The base plate 303, made of soft sponge material, covers the irregularly shaped cold coil 302 to form a... The flat surface also avoids direct contact with the cold coil 302. The partition 304 isolates the operating station from the cooling chip 301. The insulation plate 305 wraps around the inside of the operating box 1 to insulate the temperature and slow down the temperature rise. The heat exchanged by the cooling chip 301 is dissipated to the outside through the heat dissipation hole 306 on the left side. At the same time, the temperature sensor 307 monitors the internal temperature in real time, allowing the experimenter to control the cooling effect of the cooling chip 301 by adjusting the panel 308. This can keep the internal temperature of the operating box 1 constant, providing a good low-temperature environment for the test and reducing the impact of temperature on the experiment.

[0026] Furthermore, the operating box 1 itself has a storage mechanism 4, which can store various solutions and instruments required for the test at low temperatures. The top of the base plate 303 has multiple storage slots 401 of different sizes. The smaller storage slots 401 are used to store reagent bottles 402, which can hold solid particles or solutions required for the experiment. The larger storage slots 401 are used to store instruments. The most important ones are the filter bottle 403 and the jacketed funnel 404. The filter bottle 403 and the jacketed funnel 404 can be used together for filtration. Since the pretreatment causes fluorosilicate to react with potassium ions to form potassium fluorosilicate precipitate, the filter bottle 403 and the jacketed funnel 404 need to be combined and placed on the operating platform 405 on the base plate 303 to separate the precipitate from the solution and eliminate its interference with subsequent detection. The operating platform 405 is close to the cooling coil 302, which has a good cooling effect, assists the experiment, and centrally stores the chemical materials and instruments required for multiple experiments, which is convenient for quick use and provides a beneficial low-temperature environment, improving the accuracy and convenience of the experiment.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
