Description

Technical Field

[0001] The present invention relates to the technical field of uranium ore sampling, and in particular to an in-situ precise sampling device and a sampling method for a high-precision sandstone-type uranium ore. Background Art

[0002] Sandstone uranium deposits are one of the important types of uranium resources, widely distributed around the world, with the characteristics of shallow burial, wide distribution, and complex ore body morphology. Traditional uranium sampling technology mainly relies on manual sampling or simple mechanical drilling equipment. These methods have many shortcomings in actual operation and are difficult to meet the high requirements of modern uranium resource development for sampling accuracy and safety.

[0003] In the existing technology, the uranium ore sampling process usually faces the following problems and shortcomings:

[0004] Insufficient sampling accuracy: Traditional sampling equipment is often unable to accurately sample the target ore body due to the limitations of equipment accuracy and the complexity of geological conditions when sampling uranium ore. Problems such as vibration, equipment displacement, and drill rod deviation during drilling result in large deviations in sampling position and depth, affecting the representativeness and accuracy of the samples. In addition, traditional sampling methods mostly rely on manual operations, which makes it difficult to ensure the stability and consistency of sampling.

[0005] Uneven sample processing: In existing uranium ore sampling technology, the collected ore samples are often not fully processed and used directly for analysis. Since the ore is not fully crushed and evenly distributed during the sampling process, the particle size of the samples is inconsistent, which in turn affects the accuracy of the chemical analysis results. Traditional sampling equipment lacks an effective sample processing system and cannot evenly crush and screen the samples on site, affecting the reliability of the analytical data.

[0006] Insufficient environmental and operational safety: Uranium ore is radioactive. During the sampling and processing process, the spread of ore dust and the leakage of radioactive materials may pose serious safety hazards to operators and the surrounding environment. Traditional sampling equipment usually lacks effective dust control and radiation protection measures, resulting in greater environmental risks in sampling operations. In addition, the design of the equipment does not fully consider the safety needs of operators, which is easy to cause radiation exposure and difficult to ensure safety during operation.

[0007] To this end, those skilled in the art provide a high-precision sandstone-type uranium ore in-situ precise sampling device and a sampling method thereof to solve the problems raised in the above-mentioned background technology. Summary of the invention

[0022] The method for in-situ precise sampling of sandstone-type uranium ore is used to use a high-precision in-situ precise sampling device for sandstone-type uranium ore, including the following steps:

[0023] S1. Geological exploration and modeling: In the predetermined sampling area, seismic wave imaging and magnetic exploration are used to establish a three-dimensional geological model of the underground uranium ore body to clarify the location, shape and depth of the uranium ore body. After the exploration is completed, the precise sampling point location is determined by differential GPS;

[0024] S2. Equipment preparation: Place the sampling device equipped with a stabilizing frame at the determined sampling point, support and fix it with a vertical pole to make the device stable and vertical to the ground, ensure that the support frame is firmly installed on the top of the vertical pole and fixed with a connecting frame, and use a reinforcing component to stabilize the connection position of the support frame;

[0025] S3, sampling preparation: start the first motor, drive the transmission rod to rotate through the first pulley and the second pulley, and drive the drill rod to rotate through the meshing of the first gear and the second gear, so that the drill rod and the drill bit are drilled to a predetermined sampling depth, and the drilling direction and depth are accurately controlled according to the geological model;

[0026] S4. Crushing of uranium ore: When the drill bit reaches the target depth, the crushing system in the processing box is started, and the synchronous rod is driven by the motor to rotate, driving the first crushing roller and the second crushing roller to work together, and the collected uranium ore is transported to the processing box through the feed trough. The uranium ore is first crushed by the first crushing roller and the second crushing roller, and then crushed to the required particle size under the sieve hole at the top of the slope leakage block;

[0027] S5. Environment and safety management: Use sealing lead plates to seal the sampling area to reduce the leakage of radioactive materials and ensure the safety of operators and the environment. The sampling equipment is wound and unwound by the steel cable and the reel to ensure the stability of the device and the flexibility of operation.

[0028] S6. Post-sampling processing: After sampling is completed, the uranium ore samples in the sampling container will be numbered and sealed, ready to be sent to the laboratory for further analysis, and the sampling device and related equipment will be inspected and maintained to ensure that the equipment is in good condition when it is used next time.

[0029] Working principle: Through geological exploration and positioning, a three-dimensional model of the underground uranium ore body is established using seismic wave imaging and magnetic exploration, and the differential GPS system is used to accurately determine the location of the sampling point to ensure that the sampling device is in the best position. The device mainly includes key parts such as support components, processing components, sampling components and weakening components.

[0030] The support assembly consists of a stabilizing frame, a vertical pole and a connecting frame, which is installed on the top of the stabilizing frame. The vertical pole supports the equipment vertically, so that the entire device is firmly and reliably fixed at the sampling location, ensuring the stability and verticality of the equipment during the sampling process. The bearing frame is installed on the top of the support assembly and fixed to the vertical pole through reinforcing components and contact rods to ensure that the bearing frame will not shake or move during the sampling process, maintaining the high-precision operation of the entire device.

[0031] The processing assembly is installed on the carrier frame, and its core part is the processing box, which includes a motor, a synchronous rod, a first movable rod, a second movable rod, and a matching crushing system. The motor outputs power, and drives the conveying plate in the processing box to slide through the synchronous rod, lifts the uranium ore entering from the feed trough, and guides it to the crushing roller near the top of the processing box for preliminary crushing. The two crushing rollers are driven by the first movable rod and the second movable rod, and rotate precisely and synchronously through the third gear and the fourth gear respectively to ensure that the ore is evenly crushed to the required particle size. The crushed ore is filtered through the sieve holes on the top of the slope filter block. Spring rods and oscillation motors are installed on both sides of the filter block. Through slight vibration, the ore is evenly distributed, which further enhances the crushing and filtering effects.

[0032] The sampling assembly is arranged on one side of the processing assembly, including a drill rod, a rotating shaft and a drill bit, and is driven by a power component installed on one side of the top of the carrier. The first motor rotates the transmission rod through the pulley system and the connecting transmission rod, and drives the drill rod and the rotating shaft to rotate accurately through the meshing of the first gear and the second gear to achieve the drilling of uranium ore. The collected uranium ore is transported to the top of the processing assembly through the auger in the rotating shaft for preliminary crushing.

[0033] The crushed uranium ore enters the transparent acrylic tube through the feed trough. The design of the acrylic tube can provide a transparent effect, which is convenient for the staff to observe the flow of the ore in real time, ensuring the smooth sampling and the accuracy of the processing. The ore is transported from the acrylic tube to the dust reduction bin in the weakening component. In the dust reduction bin, the nozzle connected to the top water tank sprays water mist for dust reduction treatment, effectively controlling the generation of dust. The ore after dust reduction is filtered through the filter layer for water filtration, and the filtered water is recycled into the water tank for recycling, ensuring that the operation is environmentally friendly and economical. At the same time, the inner wall of the dust reduction bin is provided with a filter plate to further purify the treated water quality. In order to ensure the safety of operation, a sealing lead plate is provided on one side of the dust reduction bin to effectively isolate the radioactive substances inside during the sampling and processing process to prevent radiation leakage.

[0034] During the entire sampling and processing process, the equipment is connected to the reducer through the second motor in the reinforcement component to drive the reel to rotate, thereby pulling the steel cable connected to the carrier frame to complete the precise lifting and lowering adjustment of the sampling equipment, ensuring the operational stability and flexibility of the equipment at different sampling depths. After the sampling is completed, the staff can safely retract and release the device through the steel cable and reel system, and number and seal the samples for storage, ready to be sent to the laboratory for further analysis.

[0035] The present invention provides an in-situ precise sampling device and a sampling method for high-precision sandstone-type uranium ore.

[0036] It has the following beneficial effects:

[0037] 1. The present invention can achieve accurate sampling and processing of sandstone-type uranium ore through a precisely controlled sampling component and a multi-stage crushing system, ensure the representativeness and uniformity of the sample, and provide high-quality samples for subsequent analysis.

[0038] 2. The present invention adopts the design of transparent acrylic tube and dust suppression chamber, so that the operator can monitor the sampling process in real time and adjust the operation in time. Combined with the radiation protection measures of the sealed lead plate, the safety of the sampling operation is effectively guaranteed and environmental pollution is reduced.

[0039] 3. The present invention supports and strengthens the component design, ensuring the stability of the equipment under different conditions. At the same time, through the water resource recycling system of the dust suppression chamber, environmentally friendly and efficient radiation dust control is achieved, reducing operating costs.

DETAILED DESCRIPTION

[0050] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0051] Embodiment 1:

[0052] Please see attached Figure 1 The embodiment of the present invention provides a high-precision sandstone-type uranium ore in-situ precise sampling device, which is designed for high-precision in-situ sampling of sandstone-type uranium deposits. The device combines a support component, a processing component, a sampling component, and a weakening component to ensure accurate positioning, stable operation, efficient processing, and safe dust control and radiation protection during the sampling process.

[0053] Please see attached Figure 1 -Attached Figure 3 The support assembly is the basic structure of the device, which is designed to provide stable support for the entire sampling device. The support assembly includes a vertical pole 2 installed on the top of the stabilizing frame 1. The vertical pole 2 is perpendicular to the ground and is firmly connected to the stabilizing frame 1 through a connecting frame 8 to ensure that the device remains stable during the sampling process. In order to further enhance the stability of the device, a reinforcing component is provided on one side of the top of the stabilizing frame 1 to strengthen the connection between the supporting frame 3 and the vertical pole 2. Contact rods 10 are also installed on both sides of the supporting frame 3 to ensure that the supporting frame 3 is fixed in position during the sampling process and will not be displaced due to vibration or external force.

[0054] Please see attached Figure 2 , Attachment Figure 5 , Attachment Figure 6The processing assembly is installed on the top of the carrier 3, and is mainly used to drive the sampling assembly to adjust the mining depth and perform preliminary processing on the collected uranium ore. The core of the processing assembly is the processing box 16, inside which are installed the first movable rod 17 and the second movable rod 19, which are synchronously driven by the third gear 21 and the fourth gear 22 respectively, to ensure the coordinated operation of the first crushing roller 18 and the second crushing roller 20. The crushing roller is installed on the outer wall of the movable rod and is used to perform preliminary crushing on the collected uranium ore.

[0055] Please see attached Figure 6 -Attached Figure 7 A motor 23 is installed on one side of the processing box 16. The motor 23 drives the synchronous rod 24 to rotate, driving the conveying plate 25 to slide along the inner wall of the processing box 16. The uranium ore enters the processing box 16 through the feed trough 28. After the initial crushing, it is lifted up by the conveying plate 25 and crushed again by the crushing roller. The crushed uranium ore is discharged through the sieve holes of the slope leakage block 27 on the top of the processing box 16 to ensure that the particles meet the required particle size standards. In order to ensure the uniformity of the crushing process, an oscillation motor is installed on one side of the slope leakage block 27, which makes the ore evenly distributed above the sieve holes through slight vibration in conjunction with the spring rod 26.

[0056] Please see attached Figure 1 The sampling assembly is responsible for accurately collecting uranium ore from underground. The assembly includes a drill rod 5, a rotating shaft 6 and a drill bit 7, which are driven by a power component. The power component is installed on one side of the top of the carrier 3, and is mainly composed of a first motor 9. The motor is connected to the transmission rod 13 through the first pulley 11 and the second pulley 12. The rotation of the transmission rod 13 is meshed with the second gear 15 through the first gear 14, further driving the first movable rod 17 and the second movable rod 19 to rotate, thereby driving the drill rod 5 and the rotating shaft 6 to rotate synchronously. The drill bit 7 goes deep into the ground for accurate ore sampling.

[0057] An auger is provided inside the rotating shaft 6 for conveying the collected uranium ore from underground to the top of the processing assembly, and after preliminary crushing, it is conveyed into the processing box 16 for further processing.

[0058] Please see attached Figure 8 The weakening assembly is installed on the top of the stabilizing frame 1 to control dust and prevent the spread of radioactive substances. After the uranium ore is crushed by the processing assembly, it is transported to the dust suppression bin 30 through the feed trough 28 and the transparent acrylic tube 29. The acrylic tube 29 adopts a transparent design, so that the operator can observe the flow of uranium ore in real time to ensure that the ore enters the dust suppression bin 30 smoothly.

[0059] Please see attached Figure 8In the dust suppression bin 30, the water tank 31 connected to the top is connected to multiple nozzles 32 through pipelines. The nozzles 32 spray water mist to the incoming uranium ore to effectively control the diffusion of dust. A filter layer 33 is provided at the bottom of the dust suppression bin 30 to filter the sprayed water. The purified water is transported back to the water tank 31 through a pipeline to achieve recycling, which is environmentally friendly and efficient. A sealing lead plate 34 is also provided on one side of the dust suppression bin 30 to prevent leakage of internal radioactive materials when the equipment is closed to ensure safe operation.

[0060] Please see attached Figure 3 -Attached Figure 4 The operation of the device is controlled by a strengthening assembly, which includes a second motor 35, which is connected to a reducer 36 through a belt to control the rotation speed of a reel 37. The reel 37 is connected to the carrier 3 through a steel cable 38, which is responsible for the lifting and lowering adjustment of the sampling device to ensure the operational stability of the device at different depths.

[0061] Please see attached Figure 3 During the operation, the staff accurately controls the drilling depth according to the geological model, starts the first motor 9, and drives the drill rod 5 and the rotating shaft 6 through the power transmission system to take samples. After the collected uranium ore is crushed and screened, it is transported to the dust suppression chamber 30 through the acrylic tube 29 for dust treatment and radiation protection. After the treatment is completed, the sample is sealed and stored, ready to be sent to the laboratory for further analysis. The operator retracts and releases the equipment through the steel cable 38 and the reel 37 system to ensure that the sampling device is in the best condition before the next use.

Equipment preparation: Place the sampling device equipped with the stabilizing frame (1) at the determined sampling point, support and fix it with the vertical pole (2) to make the device stable and vertical to the ground, ensure that the supporting frame (3) is firmly installed on the top of the vertical pole (2), and fix it with the connecting frame (8), and use the reinforcing component to stabilize the connection position of the supporting frame (3); S3, sampling preparation: start the first motor (9), drive the transmission rod (13) to rotate through the first pulley (11) and the second pulley (12), and drive the drill rod (5) to rotate through the meshing of the first gear (14) and the second gear (15), so that the drill rod (5) and the drill bit (7) are drilled to a predetermined sampling depth, and the drilling direction and depth are accurately controlled according to the geological model; S4, crushing of uranium ore: when the drill bit (7) reaches the target depth, the crushing system in the processing box (16) is started, and the synchronous rod (24) is driven to rotate by the motor (23), driving the first crushing roller (18) and the second crushing roller (20) to work together, and the collected uranium ore is transported to the processing box (16) through the feed trough (28). The uranium ore is firstly crushed by the first crushing roller (18) and the second crushing roller (20), and then crushed to the required particle size under the sieve hole at the top of the slope leakage block (27); S5. Environment and safety management: Use sealing lead plates (34) to seal the sampling area to reduce the leakage of radioactive substances and ensure the safety of operators and the environment. The steel cable (38) and the reel (37) are used to complete the reeling and unreeling operation of the sampling device to ensure the stability of the device and the flexibility of operation. S6. Post-sampling processing: After sampling is completed, the uranium ore samples in the sampling container will be numbered and sealed, ready to be sent to the laboratory for further analysis, and the sampling device and related equipment will be inspected and maintained to ensure that the equipment is in good condition when it is used next time.
