Description

Technical Field

[0001] This utility model relates to the field of water solubility testing, and in particular to a device for testing the water solubility of solid potassium salt ore. Background Technology

[0002] Solid potash is a non-metallic mineral with potassium chloride and sulfate minerals as its main components. It is usually found in the Earth's crust or in dried-up lakes and ocean brines. The solid potash water solubility test device is a device used to simulate and test the performance parameters of solid potash during the water dissolution process. By simulating the water solubility performance test, it provides basic parameter data for water-soluble mining, ore processing and mining technology conditions.

[0003] Existing experimental apparatuses for the water solubility of solid potash ore typically employ an integrated structure. Experimenters need to prepare the solution first, and then place the solid potash ore sample into the apparatus for reaction. Throughout the process, experimenters need to closely monitor the operating status of the apparatus to ensure the smooth progress of the experiment, which limits both flexibility and efficiency.

The main reaction component is responsible for conducting water solubility experiments on solid potassium salt ore, while the solvent preparation auxiliary component is specifically responsible for preparing the solution. This not only reduces waiting time during the experiment and improves experimental efficiency, but also makes the experiment more flexible. Utility Model Content

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Solid potash ore refers to solid ores containing potash minerals. Potash refers to mineral salts containing potassium, and its main components are compounds formed by the combination of potassium ions and various acid radicals. These ores exist in a solid state in the natural environment and are one of the important sources of potassium.

[0025] Common potassium salt minerals include halite, carnallite, and potassium magnesium sulfate. Halite is one of the most important potassium salt minerals, with a high potassium chloride content, and is an important raw material for the production of potassium fertilizer. Carnallite contains magnesium chloride and water of crystallization. In addition to extracting potassium, magnesium chloride also has certain industrial uses.

[0026] Formation and distribution

[0027] Formation process: The formation of solid potash deposits is mainly related to the evaporation and concentration of ancient oceans or salt lakes. During geological history, closed or semi-closed bays, salt lakes and other water bodies gradually concentrated the salt in the seawater or lake water after long-term evaporation. When the concentration of potassium ions and other ions reached a certain level, they crystallized to form potash deposits. For example, in some geological depressions, after seawater or lake water converged, it continued to evaporate under arid climatic conditions, and the salt precipitated at the bottom. After a long geological process, thick potash deposits were formed.

[0028] Geographical Distribution: Potash deposits are relatively concentrated worldwide. Saskatchewan, Canada, is one of the world's largest potash producing regions, with abundant potash reserves and thick ore layers. The Ural region of Russia is also an important potash producing area with a long history of potash mining. In addition, countries such as Germany and Belarus also have large potash resources. In my country, the Qaidam Basin in Qinghai is the main potash mining area, with considerable reserves of solid potash, providing an important raw material guarantee for my country's potash fertilizer production.

[0029] Mining methods

[0030] Underground mining: For deep-buried solid potash deposits, underground mining is usually adopted. This method requires excavating underground tunnels such as shafts and horizontal tunnels to reach the potash ore body. Miners use mining equipment to extract the potash ore underground, and then use hoisting equipment to transport the ore to the surface. Underground mining faces challenges such as complex geological conditions, such as rock stability and groundwater, and requires effective support and drainage measures to ensure mining safety.

[0031] Open-pit mining: When potash deposits are shallow, open-pit mining is a feasible method. Potash ore is directly mined by stripping away the rock and soil covering the ore body. The advantages of open-pit mining are high mining efficiency and the ability to use large mining and transportation equipment, such as excavators and dump trucks. However, open-pit mining will cause significant damage to the surface environment, requiring subsequent environmental restoration work such as land reclamation.

[0032] use

[0033] In the agricultural sector, the primary use of solid potash ore is in the production of potash fertilizer, an indispensable fertilizer in agricultural production. Potash fertilizer can improve the lodging resistance of crops, enhance photosynthesis, and increase crop yield and quality. For example, when planting grain crops such as wheat and corn, as well as cash crops such as bananas and citrus, the application of potash fertilizer can significantly improve crop growth.

[0034] In the industrial sector: In addition to being used in the production of potash fertilizer, potash salts have a wide range of industrial applications. In the glass industry, potash salts can lower the melting temperature of glass and improve its transparency and gloss. In the chemical industry, potash salts can be used to produce potassium hydroxide, which is used as a chemical raw material in the manufacture of soaps, detergents, and other products. In the pharmaceutical field, potash salts can be used as a drug ingredient to regulate the electrolyte balance in the human body.

[0035] The solid potash ore water solubility test apparatus is mainly used to study the solubility characteristics of potash ore in specific solvents (water, brine, inorganic acids and salts, organic solvents, etc.), including the dissolution rate and extent, in order to optimize potash ore mining and processing technology, assess environmental impact, and develop new materials and technologies.

[0036] Application of the device:

[0037] The solid potassium salt ore water solubility test device is mainly used to obtain the water solubility parameters of ore mined by underground water mining of salt deposits.

[0038] By simulating water solubility performance tests, basic parameter data are provided for water-soluble mining, ore processing, and mining technology conditions.

[0039] Device composition:

[0040] Although the specific apparatus may vary depending on the experimental purpose and requirements, such apparatus typically includes sections for simulating different rock or mineral layers, as well as sections for storing and adding solvents.

[0041] For example, some experimental setups may include components such as a box, solvent storage, tubing, and water outlet. The box may have internal partitions that divide the interior into multiple simulation zones to fill the mineral-bearing strata and simulate different mining processes.

[0042] Experiment content:

[0043] The experiments typically include the determination of parameters such as the lateral dissolution rate, lateral dissolution angle, water dissolution rate, and dissolution rate of the mineral core.

[0044] It may also involve the detection of indicators such as brine composition, concentration, expansion rate, physical properties and salt content of water-insoluble residues.

[0045] Importance of the experimental setup:

[0046] An experimental apparatus for the water solubility of solid potash ore is of great significance for the mining and utilization of potash. Simulation experiments using this apparatus allow for a more accurate understanding of the water solubility of potash ore, providing a basis for developing reasonable mining plans and technical parameters. Furthermore, the apparatus can be used to study the impact of different mining methods on the water solubility of potash ore, and to explore new ways to improve mining efficiency and reduce mining costs.

[0047] Experimental apparatus for the water solubility of solid potash ore is crucial, serving as a key tool for studying its solubility characteristics. It plays an indispensable foundational role in optimizing mining and processing, assessing environmental impact, and developing new materials and technologies. However, such apparatus often encounters problems in practical use. Below are some common issues and their causes: 1. Accuracy Issues: Inaccurate experimental data fails to accurately reflect the water solubility of potash ore. Causes: This may be due to an unreasonable design of the apparatus, leading to inaccurate control of experimental conditions. Fluctuations in parameters such as temperature, pressure, and solution concentration can affect the accuracy of the results. 2. Equipment Stability Issues: Malfunctions occur during operation, affecting the continuity and stability of the experiment. Causes: The equipment itself may have manufacturing defects, or prolonged use may cause aging and wear, leading to malfunctions. Improper experimental operation can also damage the equipment. 3. Efficiency Issues: The experiment is too time-consuming and inefficient. Causes: This may be due to an underoptimized apparatus design, resulting in cumbersome experimental procedures, or limited equipment processing capacity that cannot meet the needs of rapid experiments. Meanwhile, the skill level of the experimental operators can also affect experimental efficiency. 4. Solution Management Issues: Improper preparation, storage, and management of solutions can affect experimental results. Reason: Solution preparation may require precise ratios and strict storage conditions. Poor management can lead to solution deterioration, concentration changes, and other problems, thus affecting the accuracy of experimental results. 5. Environmental Adaptability Issues: Poor adaptability of the experimental apparatus to the environment makes it impossible to conduct stable experiments under different environmental conditions. Reason: This may be because the design of the experimental apparatus did not fully consider changes in environmental factors, such as temperature, humidity, and air pressure, leading to unstable performance of the experimental apparatus under different environmental conditions.

[0048] In summary, the experimental apparatus for the water solubility of solid potassium salt ore may encounter various problems in actual use, including issues with experimental accuracy, equipment stability, experimental efficiency, solution management, and environmental adaptability. These problems may be caused by a variety of factors, such as the design and manufacturing quality of the experimental apparatus, improper operation, and environmental factors. To improve the accuracy and stability of the experimental apparatus, it is necessary to continuously optimize its design, strengthen equipment maintenance and upkeep, improve the skill level of operators, and strictly control experimental conditions and environmental factors.

A ring 104 is fixedly connected to the end of the first barrel 101. A handle 105 is fixedly installed on the upper end of the ring 104. An inlet pipe 109 is fixedly installed at the bottom left end of the first barrel 101. A first outlet pipe 110 is fixedly installed at the bottom right end of the first barrel 101. A first valve 111 for controlling the inlet and outlet of the solution is provided on the outer side of the upper end of the inlet pipe 109 and the first outlet pipe 110. A filter screen 112 is provided on the inner side of the first barrel 101 at the corresponding positions of the inlet pipe 109 and the first outlet pipe 110. Two sets of limiting strips 114 are fixedly installed symmetrically on both ends of the filter screen 112 on the inner side of the first barrel 101. A slot 115 is opened at the upper end of the limiting strip 114. Two sets of locking strips 113 for engaging with the slot 115 are fixedly connected to the upper side of the filter screen 112.

[0051] Please see Figures 6-7In this embodiment, the solvent preparation auxiliary component includes a second tank 201, a feeding port 202, a semi-circular cover 203, a drive motor 204, a rotating shaft 205, a stirring rod 206, a second outlet pipe 207, a second valve 208, and a support frame 209. The feeding port 202 is located on the upper right side of the second tank 201, and a semi-circular cover 203 for opening and closing is located on the outer side of the feeding port 202. The drive motor 204 is fixedly installed in the middle of the upper end of the second tank 201, and a rotating shaft 205 is fixedly connected to the lower end of the drive motor 204. The rotating shaft 205 passes through the second... The upper end of the barrel 201 extends to the inner bottom. Stirring rods 206 are linearly distributed and evenly fixedly installed around the surface of the rotating shaft 205. The drive motor 204 drives the rotating shaft 205 to rotate, causing the stirring rods 206 to rotate synchronously. A second liquid outlet pipe 207 for introducing the prepared solution into the main reaction component is fixedly installed at the bottom right end of the second barrel 201. A second valve 208 for controlling the entry and exit of the solution is provided at the upper end of the second liquid outlet pipe 207. A support frame 209 for supporting the second barrel 201 is fixedly installed at the lower end of the second barrel 201.

[0052] When working, first place the main reaction component and the solvent preparation auxiliary component in their respective positions, and connect the liquid inlet pipe 109 of the main reaction component and the second liquid outlet pipe 207 of the solvent preparation auxiliary component through the hose 3.

[0053] Open the sealing cover 106 again, put the sample holder 103 with the sample in it into the first passage, lift the sample holder 103 with the handle 105 and place it in the corresponding position, and then close the sealing cover 106.

[0054] Then open the semi-circular cover 203 and add the ingredients for preparing the solvent into the second tank 201 through the feeding port 202. Then close the semi-circular cover 203. During the solvent preparation process, the drive motor 204 drives the rotating shaft 205 to rotate the stirring rod 206 to add the solvent.

[0055] After the solution is prepared, open the second valve 208 and the first valve 111 on the outside of the second outlet pipe 207 and the inlet pipe 109 to introduce the prepared solvent into the first tank 101 to react with the internal sample. During the reaction, the pressure is controlled by an external pressurizing device, and the liquid level change inside the first tank 101 is observed by a millimeter scale 108.

[0056] Finally, after the reaction is completed, open the first valve 111 on the outside of the first outlet pipe 110 to export the solution to the corresponding position. During the process of solution entering and exiting, the filter screens 112 on the inner sides of the left and right ends of the first tank 101 prevent the solvent from directly impacting the solute sample and causing damage, and prevent solid residue from flowing out with the liquid during the exit, causing blockage and measurement error.

[0057] When the filter screen 112 needs to be replaced and cleaned, the filter screen 112 can be removed directly, and the locking strip 113 on the filter screen 112 can be separated from the locking groove 115 of the limiting strip 114.

[0058] In some special cases, the pressurization equipment can be connected to an external pressurization device, such as when it is necessary to improve the dissolution rate and efficiency, simulate actual mining conditions, study special physicochemical processes, or overcome mass transfer resistance.

[0059] By employing the above steps and setting up a modular experimental device for the water solubility properties of solid potassium salt ore, consisting of a main reaction component and a solvent preparation auxiliary component, the main reaction component can be responsible for conducting experiments on the water solubility properties of solid potassium salt ore, while the solvent preparation auxiliary component is specifically responsible for solution preparation. This not only reduces waiting time and improves experimental efficiency but also makes the experiment more flexible. This addresses the problem that existing experimental devices for the water solubility properties of solid potassium salt ore typically adopt an integrated structure, requiring experimenters to prepare the solution first and then place the solid potassium salt ore sample into the device for reaction. Throughout the process, experimenters need to closely monitor the operating status of the device to ensure the smooth progress of the experiment, which limits both flexibility and efficiency.
