Description

Technical Field

[0001] This invention relates to the field of testing and sample preparation equipment technology, specifically to an intelligent device and method for ore testing and sample preparation. Background Technology

[0002] Ore testing is a core supporting link in the entire chain of mineral resource development and utilization. Its core purpose is to accurately analyze key indicators such as ore composition and physicochemical properties, monitor ore quality fluctuations in real time during the mining and beneficiation process, optimize beneficiation process parameters, improve the recovery rate of useful minerals, and reduce production costs.

[0003] Referring to the coal testing crushing and screening sample preparation equipment disclosed in patent application CN120869734A, this patent features continuous and efficient operation capabilities: the homogenization and reduction mechanism is driven by a chain reciprocating mechanism, circulating and displacing on a closed-loop slide to achieve uninterrupted continuous operation. The sample is fed into the hopper → mixed → reduced → residual material discharged → reset to receive new material, all fully automated, significantly improving sample preparation efficiency. Multiple sets of homogenization and reduction mechanisms simultaneously handle different batches of samples, forming a multi-batch, multi-state parallel processing mode, shortening the single operation cycle, and suitable for high-frequency sample preparation needs.

[0004] The sample preparation equipment in the above-mentioned prior art has the following defects in actual use: During the grinding stage, ore testing and sample preparation equipment inevitably generates high temperatures due to friction. Volatile components in the ore volatilize when heated, resulting in lower detection values ​​for these components. Furthermore, easily oxidized minerals are more easily oxidized at high temperatures, causing changes in element valence states or the formation of new compounds, deviating from the original component ratio. This leads to test results that do not match reality and fail to accurately reflect the true composition of the ore.

[0005] Therefore, this invention proposes an intelligent device and method for ore testing and sample preparation to solve the above problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an intelligent device and method for ore testing and sample preparation. It solves the problem that during the grinding stage of ore testing and sample preparation equipment, unavoidable high temperatures are generated due to friction. This causes volatile components in the ore to volatilize, resulting in lower detection values ​​for these components. Furthermore, easily oxidized minerals are more readily oxidized at high temperatures, leading to changes in element valence states or the formation of new compounds, deviating from the original component ratios. Consequently, the detection results do not match the actual composition of the ore and fail to accurately reflect its true composition.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: an intelligent device for ore testing and sample preparation, comprising a shell, a 600g mixing and reducing machine, a grinding machine, an ultrasonic vibrating screen, a 200g mixing and reducing machine, a three-axis module, a waste collector, and a control system; The 600g mixing and reducing machine, grinding machine, ultrasonic vibrating screen, 200g mixing and reducing machine, and three-axis module are electrically connected to the control system.

[0016] This invention also discloses a sample preparation method for ore testing, employing an intelligent device for ore testing sample preparation. The method includes the following steps: Step 1: After manual weighing, the material is fed into the 600g mixing and dividing machine through the feed inlet. The material is divided into three 200g portions: one for reference, one for rinsing, and one for grinding. The reference sample is fed into the packaging port through the three-axis module for packaging. Step 2: Then, the rinse sample is sent into the grinder, ground, collected through the waste collector, and then the ground sample is put back into the grinder for formal grinding. Step 3: After grinding, the material enters the ultrasonic vibrating screen for screening. The material on the screen is collected by the waste collector, and the material under the screen enters the 200g mixing and reducing machine to divide the material evenly into three parts. The material is then sent to the sampling port for packaging through the three-axis module.

[0017] This invention provides an intelligent device and method for ore testing and sample preparation. Compared with the prior art, it has the following advantages: 1. An intelligent device and method for ore testing and sample preparation, which automates the entire process from primary material reduction, sorting, secondary material reduction, to finished product packaging, relying on a control system and a three-axis module. A 600g mixing and reducing machine automatically completes the initial material separation, while the three-axis module precisely picks up the test samples and qualified finished products and transfers them to the corresponding packaging ports, eliminating the need for manual material handling. The grinding mill automatically switches between "clean grinding" and "formal grinding" modes, and the ultrasonic vibrating screen and the 200g mixing and reducing machine seamlessly connect to the screening and secondary material reduction process. Compared to the traditional manual material separation combined with manual transfer, this significantly reduces the number of manual operation steps. This reduces labor costs while avoiding sample contamination caused by human contact. The 600g mixing and reducing machine, with its built-in stirring and dispensing structure, accurately divides the input material into three 200g sub-materials (sample for reference, rinsing sample, and grinding sample). The reduction error is small, providing uniform initial material for subsequent processing and avoiding differences in grinding and sieving effects caused by uneven initial separation. Secondly, the 200g mixing and reducing machine further divides the qualified undersize material after ultrasonic sieving into three equal portions of finished product, ensuring the particle size consistency and representativeness of the final sample. This is especially suitable for fields with high sample accuracy requirements.

[0018] 2. An intelligent device and method for ore testing and sample preparation, wherein the "clean grinding" mode of the grinding mill is used to process the rinse sample in advance to clean the grinding channel and avoid contamination of the subsequent formal grinding sample by residual impurities, thus ensuring the purity of the grinding sample; the "formal grinding" mode processes according to a preset particle size to meet the fineness requirements of different materials; the ultrasonic vibrating screen achieves precise separation of "oversize material" and "undersize material" through high-frequency vibration, while avoiding the problem of material clogging the screen in traditional screening, improving screening efficiency and accuracy, ensuring that the material entering the secondary reduction is of qualified particle size, and reducing the quality fluctuation of the subsequent finished product.

[0019] 3. An intelligent device and method for ore testing and sample preparation, wherein the system connects a grinder and an ultrasonic vibrating screen through a dedicated pipeline to centrally transport the grinding waste and oversize waste of the washing sample to the processing unit: first, the waste is filtered by a dust removal device to prevent dust from spreading into the air and causing environmental pollution; then, the filtered solid waste is collected in a storage box for easy unified cleaning and disposal in the later stage, achieving the environmental protection effect of "no waste on the ground and no dust diffusion"; secondly, the crushing and screening inlet of the outer shell is directly connected to the feeding channel of the 600g mixing and reducing machine, which not only ensures that the material is free of residue and enters the reducing stage smoothly, but also avoids dust overflow when the material is fed in. Together with the waste collector, it forms a full-process environmental protection control system of source dust prevention and end dust control, thereby improving the quality of the operating environment.

[0020] 4. An intelligent device and method for ore testing and sample preparation, which automates the entire process of raw material conveying, crushing pretreatment, fine grinding, and finished product collection by setting up a grinding mill, eliminating the need for manual segmented operation and reducing intermediate waiting time; secondly, multiple grinding components are evenly distributed and perform crushing and grinding operations simultaneously, and the crushing and grinding actions are driven by the same power source, eliminating the need for additional power equipment and increasing the sample preparation rate per unit time. It adopts a two-stage processing mode of crushing pretreatment plus fine grinding. In the crushing stage, the reciprocating extrusion of the extrusion plate and the screening of the sieve holes ensure that the raw material entering the grinding stage has a uniform particle size, laying the foundation for subsequent fine grinding, while the grinding cylinder rotates... The combination of the self-rotation and reciprocating motion of the grinding roller reduces grinding dead angles, resulting in more thorough ore grinding and high powder particle size uniformity, meeting the requirements of ore testing for sample uniformity. Secondly, the cooperation between the protrusions on the inner wall of the grinding cylinder and the grinding roller enhances the agitation and grinding force of the ore, improving the grinding precision. In addition, the grinding cooling unit drives the coolant circulation through a piston plate, flowing through the coolant channels of the transmission pipe and grinding roller, carrying away the heat generated during grinding in real time. Moreover, the coolant circulation is automatically driven by mechanical action, requiring no additional power, and the one-way valve controls the flow direction, ensuring continuous and effective cooling, thereby avoiding changes in the composition of the ore sample due to high temperature and ensuring the authenticity of subsequent test results.

[0021] 5. An intelligent device and method for ore testing and sample preparation, wherein, through the coordinated design of the crushing cylinder and the ore release port, when the extrusion plate moves, the baffle slides in the clearance groove through the top rod. When the extrusion plate advances and crushes, the baffle blocks the output end of the conveying pipe to prevent raw material leakage. When the extrusion plate resets, the baffle opens to allow new raw material to enter the crushing cylinder, thereby realizing continuous supply and crushing of raw materials, avoiding mid-process stoppage for material replenishment, and ensuring continuous sample preparation.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] This invention provides two technical solutions: an intelligent device for ore testing and sample preparation, specifically including the following embodiments: like Figures 1-4 The first embodiment is shown: an intelligent device for ore testing and sample preparation, including a shell 3, a 600g mixing and reducing machine 5, a grinding mill 1, an ultrasonic vibrating screen 2, a 200g mixing and reducing machine 11, a three-axis module 7, a waste collector 9, and a control system 8.

The output shaft of the servo motor 106 rotates through the receiving box 105 and interacts with the grinding cylinder. The bottom of the grinding cylinder 103 is fixedly connected, and the top of the bearing cylinder 102 is also fixedly provided with a receiving hopper 107. The top of the receiving hopper 107 is provided with a feed inlet, and the bottom of the receiving hopper 107 is fixedly provided with a storage cylinder 108. A cross bearing frame 109 is fixedly sleeved on the outer wall of the storage cylinder 108.

[0033] In this embodiment, the grinding assembly 110 includes two slide rails 1101 fixedly disposed at the bottom of the cross support frame 109.

The output hose 11018 and the return hose 11019 are respectively connected to the liquid storage tank 1106 and the transmission pipe 1107, and the displacement limit of the piston plate 1105 will not be at the position where the output hose 11018 and the return hose 11019 are connected to the liquid storage tank 1106.

[0034] In this embodiment, a transmission tube 1107 is fixedly provided at the bottom of the sliding sleeve 1102. A first push rod 1108 is fixedly provided on one side of the outer wall of the transmission tube 1107. A guide wheel 1109 is rotatably provided at the end of the first push rod 1108. The guide wheel 1109 slides along the inner wall of the grinding cylinder 103 and can be subjected to the intermittent pushing action of multiple protrusions 112. An ore sample preparation pretreatment unit is also provided at the position opposite to the outer wall of the transmission tube 1107 and the first push rod 1108.

[0035] In this embodiment, the ore sample preparation pretreatment unit includes a crushing cylinder 11012 fixedly mounted on the outer wall of the storage cylinder 108. Multiple screening holes 11013 are evenly distributed at the bottom of the crushing cylinder 11012. An extrusion plate 11011 is also slidably and sealed inside the crushing cylinder 11012. A second push rod 11010 is fixedly mounted at one end of the extrusion plate 11011. A spring 11014 is slidably sleeved on the outer wall of the second push rod 11010, located between the crushing cylinder 11012 and the transmission pipe 1107. One end is fixedly installed on the outer wall of the transmission pipe 1107. A conveying pipe 11015 is also fixedly installed on one side of the top of the crushing cylinder 11012. The conveying pipe 11015 is used to connect the crushing cylinder 11012 and one of the ore release ports 111. A grinding roller 11016 is rotatably sealed at the bottom of the transmission pipe 1107. Cooling liquid channels 11017 are opened on both sides of the top of the grinding roller 11016. A miniature one-way valve is fixedly installed inside each cooling liquid channel 11017. The two miniature one-way valves control the flow of cooling liquid in opposite directions.

[0036] In this embodiment, the crushing cylinder 11012 is also provided with an avoidance groove 11022. A partition 11023 for blocking the output end of the conveying pipe 11015 is slidably arranged inside the avoidance groove 11022. A top rod 11024 is also fixedly arranged between the partition 11023 and the extrusion plate 11011.

[0037] The specific process is as follows: The servo motor 106 inside the support frame 101 starts, and the output shaft drives the grinding cylinder 103 to rotate inside the bearing cylinder 102. Multiple protrusions 112 on the inner wall of the grinding cylinder 103 rotate synchronously with the cylinder, providing power for the reciprocating motion of the subsequent grinding assembly 110. The ore raw material is fed into the top feed port of the receiving hopper 107, temporarily stored in the storage cylinder 108, and then enters the crushing cylinder 11012 through the ore release port 111 and the conveying pipe 11015. When the grinding cylinder 103 rotates, the protrusions 112 intermittently squeeze the guide wheel 1109 of the grinding assembly 110, pushing the transmission pipe 1107 to slide back and forth along the slide rail 1101. The transmission pipe 1107 drives the extrusion plate 11011 to reciprocate within the crushing cylinder 11012 through the second push rod 11010. The spring 11014 assists the extrusion plate 11011 to reset, crushing the ore inside the crushing cylinder 11012. When the extrusion plate 11011 moves, it drives the partition plate 11023 to slide within the clearance groove 11022 via the push rod 11024. When the extrusion plate 11011 advances for crushing, the partition plate 11023 blocks the output end of the feed pipe 11015 to prevent raw material leakage. When the extrusion plate 11011 resets, the partition plate 11023 opens, allowing new raw material to enter the crushing cylinder 11012. The crushed ore is screened through the screening holes 11013 at the bottom of the crushing cylinder 11012, and the raw material that meets the particle size requirements enters the subsequent grinding stage.

[0038] The grinding roller 11016 at the bottom of the transmission tube 1107 reciprocates with the transmission tube 1107 and rotates simultaneously under the frictional force of the rotating grinding cylinder 103. The grinding roller 11016 cooperates with the inner wall of the grinding cylinder 103 to perform secondary fine grinding on the crushed ore. When the grinding cylinder 103 rotates, the protrusions 112 on the inner wall further assist in stirring the ore, improving the grinding uniformity, and finally achieving the powder particle size required for detection.

[0039] When the transmission tube 1107 reciprocates, the push plate 1103 drives the drive column 1104 to push the piston plate 1105 inside the liquid storage tank 1106 to slide in a sealing manner. When the piston plate 1105 moves forward, the pressure inside the liquid storage tank 1106 increases, and the coolant flows out unidirectionally into the transmission tube 1107 through the output hose 11018 and the first one-way valve 11020, and then flows into the interior of the grinding roller 11016 through the coolant channel 11017 at the top of the grinding roller 11016, cooling the grinding roller 11016. When the piston plate 1105 returns to its original position, a negative pressure is formed inside the liquid storage tank 1106, and the used coolant flows back unidirectionally to the liquid storage tank 1106 through another coolant channel 11017 of the grinding roller 11016, the return hose 11019, and the second one-way valve 11021, completing the cyclic cooling. The heat dissipation fins on the outer wall of the liquid storage tank 1106 assist in cooling the coolant, ensuring a continuous and stable cooling effect. The ground ore powder falls into the receiving box 105 through multiple discharge holes 104 at the bottom of the grinding cylinder 103. The receiving box 105 discharges the collected powder through the output port for subsequent ore testing.

[0040] This invention also provides a sample preparation method for ore testing, employing an intelligent device for ore testing sample preparation, and the method includes the following steps: Step 1: After manual weighing, the material is fed into the 600g mixing and reducing machine 5 through the feed port 4. The material is divided into three 200g portions: one for inspection, one for rinsing, and one for grinding. The inspection sample is fed into the packaging port through the three-axis module 7 for packaging. Step 2: Then, the rinse sample is sent into the grinder 1, ground and collected by the waste collector 9, and then the ground sample is put into the grinder 1 for formal grinding. Step 3: After grinding, the material enters the ultrasonic vibrating screen 2 for screening. The material on the screen is collected by the waste collector 9, and the material under the screen enters the 200g mixing and reducing machine 11 to divide the material evenly into three parts. The material is then sent to the sampling port for packaging through the three-axis module 7.

[0041] Specific sample preparation process: Equipment initialization: The control system 8 first performs a self-check on all equipment to confirm that the core components such as the grinder 1, ultrasonic vibrating screen 2, 600g mixing and reducing machine 5, 200g mixing and reducing machine 11, and three-axis module 7 are in normal condition. Safety interlock confirmation: The front maintenance door 12 must be closed. This door is not only a maintenance passage for the equipment, but also has a built-in safety interlock device. The equipment start-up permission can only be triggered when it is closed to prevent personnel from being injured by accidental operation during operation. If it is necessary to check the feed passage or internal components in advance, the front maintenance door 12 can be opened for operation. After the operation, it must be closed before the equipment can be restarted. Emergency functions are ready: The "stop and record" function is linked with the control system and is always on standby. When the equipment experiences material blockage, uneven reduction, or abnormal grinding, it can stop the equipment operation with one click and record the current process node, which is convenient for subsequent troubleshooting and avoids material waste. Material introduction: After the material is weighed manually, it is fed into the equipment through the crushing and screening feed port 4. This feed port is directly connected to the feed channel of the 600g mixing and reducing machine 5. The hole diameter matches the channel size to ensure that the material is free of residue and enters the reducing stage smoothly. At the same time, it avoids dust overflow and forms a preliminary dust prevention cooperation with the subsequent waste material dust removal system. Precise material reduction: The 600g mixing and reducing machine starts up and, through its internal stirring and distributing structure, evenly divides the input material into three 200g sub-materials, which are defined as "sample for reference", "rinsing sample" and "grinding sample" respectively. This step is the basis for subsequent processing, and the accuracy of the reduction directly determines the representativeness of the subsequent samples and the stability of the process.

[0042] Grinding machine sample processing: Automated packaging led by a three-axis module The control system 8 instructs the three-axis module 7 to move to the "sample for inspection" outlet of the 600g mixing and reducing machine 5, grab the material, and transfer it to the equipment packaging port along the preset path to complete the sealing and packaging for storage. The precise positioning function of the three-axis module 7 ensures that the sample for inspection is not spilled or confused, meeting the sample traceability requirements.

[0043] Rinse sample treatment: The rinsing sample is conveyed to the grinding mill 1, where the material is refined by the high-speed rotation of the grinding disc inside the grinding mill 1. The purpose of this step is to "clean the grinding channel" and prevent the subsequent formal grinding sample from being contaminated by impurities.

[0044] The washed waste material after grinding is transported to the waste collector 9 through pipelines. The system first filters the dust in the waste material through a dust removal device, and then collects the solid waste into a storage box for easy cleaning later.

[0045] Grinding sample preparation: Formal grinding: After the rinsing sample is processed, the grinder 1 automatically switches to the "formal grinding" mode, receives the "grinding sample" output by the 600g mixing and reducing machine 5, and completes the fine processing according to the preset particle size requirements.

[0046] Ultrasonic screening: The ground material is fed into the ultrasonic vibrating screen 2, where high-frequency vibration separates the material into "oversize material" and "undersize material" of acceptable size. Ultrasonic vibration can prevent material from clogging the screen and improve screening efficiency.

[0047] Screen oversize waste treatment: The screen oversize material enters the waste collector 9 through a special pipeline and is centrally treated together with the washing sample waste, achieving zero emission pollution of unqualified materials.

[0048] Secondary reduction: The qualified material undersize is conveyed to the 200g mixing and reducing machine 11, and is evenly divided into 3 equal parts by the internal material division structure. This step further ensures the uniformity and representativeness of the final sample.

[0049] Finished product packaging and equipment shutdown: Finished product transfer and packaging: The control system 8 instructs the three-axis module 7 to move to the discharge end of the 200g mixing and reducing machine 11, grabs 3 qualified materials in sequence, transfers them to the sampling port of the equipment to complete the packaging, and forms the final usable sample.

[0050] Equipment shutdown and maintenance: After the entire process is completed, the equipment can be shut down normally through the control system 8. If it is necessary to clean up the internal residual materials or repair the parts, the front maintenance door 12 can be opened. If it is necessary to retain the current process data when shutting down, the "stop and record" function can be triggered to record the status, so as to facilitate the connection of the process when starting up next time.
