Description

TECHNICAL FIELD

[0001] The application relates to a thallium element analysis and detection device for mine water. BACKGROUND

[0002] The thallium element analysis and detection device for mine water is generally designed by combining high-sensitivity fluorescence spectroscopy technology with portability to realize rapid detection, is suitable for detection screening in mine scenes, and can adapt to complex water quality environments. The device has been applied to metal mines, coal mines and the like, and provides key technical support for water pollution early warning and safety production.

[0003] In the Chinese patent with the patent publication number CN119688943A, a thallium element on-site analysis and detection device for mine water is disclosed, which comprises a frame; a water sample storage assembly installed on one side inside the frame and used for storing mine water samples; the device integrates water sample collection, storage, transfer and detection functions, can perform real-time detection on a mine site, reduces the complexity and professional requirements of manual operation through automatic and integrated design, can detect thallium elements in water samples, can also process silt samples at the same time, provides more data support for comprehensive evaluation of mine water, is provided with an organic matter adsorption plate, a molecular sieve and an alumina sieve treatment assembly to effectively remove organic matter and odors in water samples and improve detection accuracy. However, the device in the cited document still has the following defects in specific use: 1. The water environment in a mine is complex due to the complex flow pattern of water flow and the special migration characteristics of pollutants, and the distribution of thallium elements in the water body has significant vertical differences: the surface water is easily affected by atmospheric deposition and surface runoff, the bottom water has different concentration characteristics due to sediment adsorption and microbial activity, and the stratification phenomenon is more obvious when the water depth or water flow exchange is not smooth; the design of the cited document does not fully consider this actual scene, the water sample collection mechanism adopts a sampling pipe with a fixed length, only synchronously collects multiple samples through a shunt sampling pipe, and does not design a collection function for different water layers, so that sampling can only obtain water samples of a single depth.

[0004] This single-depth sampling method can result in a lack of representativeness of the collected water samples, and cannot fully reflect the real distribution and pollution degree of thallium elements in the mine water body. If only surface water is collected, the pollution risk can be underestimated due to the undetected high-concentration thallium in the bottom layer, and if only bottom water is collected, the overall pollution level can be exaggerated. The lack of stratification data can result in the inability to trace the migration path and enrichment rules of thallium elements, and the detection results are difficult to support scientific environmental evaluation.

[0005] 2. Compared to the sludge collection component in the referenced document, which achieves automatic sludge collection through the coordinated operation of hydraulic rods, electric telescopic rods and augers, it does not integrate a pretreatment structure. However, mine sludge contains a large amount of particulate matter and organic matter, which needs to be digested and filtered before it can be used with the thallium analyzer.

[0006] In practical use, silt can easily clog the thallium analyzer's inlet, preventing the release of particulate thallium and resulting in lower test results. At the same time, high concentrations of thallium residue can contaminate water sample testing, distorting the data and affecting the accuracy of mine water use assessment.

[0007] Furthermore, the uneven water content and high viscosity of mine sludge make it prone to accumulating on the inner walls of the auger and sampling tube during collection. The accumulated sludge can hinder the rotation of the auger, reduce collection efficiency, and even cause motor overload and damage. Moreover, the residual sludge that is not cleaned can contaminate the next sample collection, causing cross-contamination. At the same time, the sticky sludge can block the sampling tube openings, preventing excess sludge from being discharged, affecting the normal collection of the sample container, and increasing the workload and cost of equipment cleaning and maintenance.

[0008] Furthermore, although the sludge collection component achieves automatic sampling, it does not integrate a pretreatment unit. The sludge must be manually transferred to an external container for digestion before testing. This design goes against the original intention of integration. Manual operation not only requires carrying additional reagents and equipment, extending the testing cycle, but also increases the risk of sample leakage and contamination during the transfer process, increasing the safety risk of thallium poisoning. At the same time, frequent manual intervention reduces testing efficiency and cannot meet the needs of rapid and accurate testing in mining sites, increasing the cost of use and the difficulty of operation.

[0009] Therefore, in view of this, the present invention proposes a device for analyzing and detecting thallium in mine water to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0010] To address the aforementioned technical problems, this invention provides a device for analyzing and detecting thallium in mine water, thereby resolving the technical issues raised in the background section.

[0014] Further, the secondary pipes in the hierarchical receiving member are uniformly distributed around the axis of the main through pipe, forming a symmetrical assembly structure around the main through pipe, the height dimension of the main through pipe along the vertical direction is consistent with the height dimension of the secondary pipes, and the end faces of the two are flush during axial assembly, the diameter ratio of the main through pipe to the secondary pipes is two to one, so as to adapt to the main conveying function of the main through pipe and the shunt receiving function of the secondary pipes.

[0015] Further, in the initial state, the groove opening and the protruding block head are in staggered positions in the circumferential direction, and do not form contact and communication; in the use state, the groove opening and the corresponding protruding block head are aligned and attached in the circumferential direction, at this time, the main through pipe and the hierarchical receiving member form a communication channel through the groove opening and the protruding block head, so as to realize the transmission of fluid between the two.

[0016] Further, the lower part of the sampling module is provided with an auxiliary module, the auxiliary module comprises a filtering accessory installed below the output end of the main through pipe for filtering the water sample, the output end of the filtering accessory is communicated with a funnel-shaped communication pipe, the communication pipe has a contraction structure of wide top and narrow bottom along the axial direction, the inner wall of the communication pipe is uniformly provided with a plurality of vibration members, and a threaded shaft column is installed at the inner center position of the communication pipe, and the outer surface is provided with a continuous spiral protrusion, which can guide the fluid to flow along the spiral path when the fluid passes through.

[0017] Further, the vibrating member is combined by a metal ball and an elastic cable, one end of the elastic cable is fixedly connected with the inner wall of the communication pipeline, and the other end is fixedly connected with the metal ball, so that the metal ball is arranged in the internal space of the communication pipeline in a suspended support mode of the elastic cable.

[0018] Further, the lower portion of the auxiliary module is provided with an adjusting module, the adjusting module comprises an adjusting rotating plate rotatably connected with the outer wall of the communication pipeline, the lower surface of the adjusting rotating plate is rotatably connected with a storage cylinder, the inside of the storage cylinder is provided with a limiting interlayer column, the limiting interlayer column is fixedly connected with the adjusting rotating plate, and the outer wall of the limiting interlayer column is uniformly fixedly connected with a plurality of inclined baffles.

[0019] Further, the outside of the limiting interlayer column is provided with a sampling guide pipe, the upper end of the sampling guide pipe penetrates through the adjusting rotating plate and is in communication with the communication pipeline, the lower end of the sampling guide pipe penetrates through the bottom of the storage cylinder, and the lower single end of the sampling guide pipe extends to the outside of the storage cylinder.

[0020] Further, the inside of the frame outer body is provided with a detector, the upper portion of the detector is correspondingly provided with a lofting table for carrying the sample to be detected, so as to be analyzed and detected by the detector.

[0021] Compared with the prior art, the beneficial effects of the present application are: (1) The present device effectively improves the problem of lack of representativeness of single depth sampling in the prior art through the cooperative design of the auxiliary module and the sampling module, the auxiliary module uses the adjusting rotating plate to make the sampling guide pipe spirally wound in the storage cylinder can be released and stretched as needed, extending to the upper layer, middle layer and deep layer of the mine water, realizing the targeted collection of samples of different water layers, fully meeting the vertical distribution difference characteristics of thallium elements in the mine water body due to factors such as water flow pattern and sediment adsorption; and the sampling module rotates around the main pipeline through the hierarchical storage member, so that the protruding heads of different secondary pipelines are aligned and fitted with the recessed openings of the main pipeline, to build an adaptive communication channel, so that water samples of different depths can be correspondingly stored in the dedicated secondary pipelines.

[0022] This "targeted collection + adaptive storage" mode can obtain thallium element samples of each depth layer of the mine water body, fully reflect the real distribution and pollution degree of thallium elements in the water body, avoid the situation that only collecting surface water may underestimate the risk of high-concentration thallium pollution in the bottom layer, and prevent the problem that only collecting bottom water exaggerates the overall pollution level, providing complete data support for tracing the migration path of thallium elements and analyzing the enrichment rules, and further ensuring the scientificity and accuracy of the environmental assessment results.

[0023] The main through pipeline and the secondary pipelines are consistent in vertical direction height and have flush axial assembly end faces, which can ensure smooth fluid passage when the two are connected, avoid the formation of liquid dead angle due to height difference, prevent residual water from affecting subsequent collection, and ensure efficient transportation of water samples of different depths to the corresponding secondary pipelines. The design of the ratio of the size of the main through pipeline to the size of the secondary pipeline being 1:1 can not only adapt to the function of the main through pipeline as a core conveying channel to bear a large flow, but also ensure that the secondary pipeline has a proper size, so as to meet the water sample storage capacity, avoid space waste caused by excessive size, make the overall structure of the sampling module more compact, and adapt to the use and installation requirements of the device in the mine site. (2) Especially important is that in actual use, the device integrates the reverse pushing function of the driving pump in the water sample collection process, effectively eliminating the hidden danger of cross contamination of different water samples in the prior art, which affects the detection results. After the water sample of a certain depth is collected, the corresponding secondary pipeline is staggered with the main through pipeline by rotating the hierarchical storage part, at which time the water sample in the secondary pipeline is retained for detection, and the driving pump is started to switch to the forward pushing mode, which can discharge the residual water sample in the main through pipeline in the original path in reverse. The reverse flowing water sample will pass through the filter accessory, the communication pipeline and the sampling guide pipe in turn, and the filter material of the filter accessory is washed in the flowing process to remove the impurities attached to the surface of the filter material in the previous depth water sample. At the same time, the inner wall of the communication pipeline, the threaded shaft column and the sampling guide pipe can also be flushed to remove the residual water sample of the previous depth.

[0024] This reverse flushing method using filtered water sample does not require additional cleaning medium, is simple to operate and clean, can effectively avoid the mixing of residual water sample of the previous depth with newly collected water sample when collecting water sample of other depths, ensures the purity and independence of each depth water sample, provides a reliable sample basis for the accurate analysis of thallium element by the subsequent detector, avoids the distortion of detection data caused by cross contamination, and ensures the accuracy and reliability of the detection results.

[0025] (3) The continuous spiral protrusions are arranged on the outer surface of the threaded shaft column in the center of the communication pipeline, which can guide the water sample to flow along the spiral path. This design can prolong the flow path of the water sample in the communication pipeline, so that the impurities in the water sample have more time to preliminarily settle under the action of gravity. At the same time, the centrifugal force generated by spiral flow can throw the impurities with higher density to the inner wall of the pipeline, reduce the impurities entering the filter accessory with the water sample, reduce the filtering load of the filter accessory, and prolong its service life. In addition, spiral flow can also avoid the adhesion of impurities caused by too fast local water flow, ensure the stable transportation of water sample to the subsequent module, provide stable fluid conditions for subsequent filtration and storage, and meet the actual scene requirements of the mine water containing more solid impurities.

[0026] (4) The vibrating member is composed of a metal ball and an elastic cable, and the metal ball is suspended in the communication pipeline. During the flow of the water sample, whether it is being extracted or discharged, the water flow will impact the metal ball, causing it to vibrate. This vibration can effectively break up any impurity agglomerates that may form in the water sample, preventing impurity clumps from adhering to the inner wall of the pipeline or the surface of the threaded shaft column, ensuring that the pipeline remains unobstructed. At the same time, the vibration can also assist the flow of the water sample, preventing local water flow from slowing down due to the pipeline's wide upper and narrow lower structure. In particular, for sticky impurities that may be present in mine water, vibration can reduce their residue in the pipeline, reducing the risk of pipeline blockage and ensuring that water samples of different depths can smoothly pass through the communication pipeline into the filtering accessory, maintaining the stability and efficiency of the overall sampling process of the device.

[0027] (5) In the adjustment module, the inclined baffle that limits the outer wall of the sandwich column can regulate and limit the sampling guide tube that is spirally wound in the storage cylinder, preventing the sampling guide tube from becoming tangled or knotted due to uneven tension during release or winding, ensuring that the guide tube always expands or is stored along an orderly path, and ensuring the accuracy of the length control of the sampling guide tube during depth adjustment. At the same time, the inclined baffle can separate the storage cylinder into relatively independent guide tube storage areas, reducing friction and wear between different parts of the guide tube and extending the service life of the guide tube. The inclined structure can assist in guiding the guide tube to fit the outer wall of the limiting sandwich column during winding, making the stored guide tube more compact, saving space inside the storage cylinder, and adapting to the overall structural layout requirements of the device.
