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, can adapt to complex water quality environments, and has been applied to metal mines, coal mines and the like to provide key technical support for water pollution early warning and safe 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 of the frame inside, 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 simultaneously improves detection accuracy.

[0004] However, the device in the cited document still has the following defects in specific use:

[0005] 1. The water environment in a mine is complex in flow pattern and special in pollutant migration characteristics, 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, while 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 flow exchange is not smooth. The design of the cited document does not fully consider this actual scene, and 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 the sampling can only obtain water samples of a single depth.

[0006] This single-depth sampling method can cause the collected water samples to lack representativeness and be unable to comprehensively reflect the real distribution and pollution degree of thallium elements in the mine water body. If only the surface water is collected, the pollution risk can be underestimated due to the undetected high-concentration thallium in the bottom layer, and if only the bottom water is collected, the overall pollution level can be exaggerated. The lack of stratification data can lead to the inability to trace the migration path and enrichment rules of thallium elements, and the detection result is difficult to support scientific environmental evaluation.

[0007] 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.

[0008] 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.

[0009] 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.

[0010] 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.

[0011] 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

[0017] Further, in the initial state, the groove opening and the protruding block head are in a staggered position 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 to realize the transmission of fluid between the two.

[0018] 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 in the axial direction, a plurality of vibration members are uniformly installed on the inner wall of the communication pipe, and a threaded shaft column is installed at the inner center position of the communication pipe, and a continuous spiral protrusion is provided on the outer surface of the threaded shaft column, which can guide the fluid to flow along the spiral path when the fluid passes through.

[0019] 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.

[0022] Further, the inside of the frame outer body is provided with a detector, and a lofting table is arranged above the detector for carrying the sample to be detected, so as to be analyzed and detected by the detector.

[0023] Compared with the prior art, the beneficial effects of the present application are:

[0024] (1) The 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 uppermost 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. 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 groove openings of the main pipeline, forming an adaptive communication channel, so that water samples of different depths can be correspondingly stored in the dedicated secondary pipelines.

[0025] 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 rule, and further ensuring the scientificity and accuracy of the environmental assessment results.

[0026] The main through pipeline and the secondary pipelines are consistent in vertical direction height and have flush axial assembly end surfaces, 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.

[0027] (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, affecting 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 member, 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, so as to reverse the residual water sample in the main through pipeline along the original path. The reverse flowing water sample will pass through the filter accessory, the communication pipeline and the sampling guide tube in turn, and the filter material of the filter accessory is washed in the flowing process to remove the impurities in the previous depth water sample attached to the surface of the filter material. At the same time, the inner wall of the communication pipeline, the threaded shaft column and the sampling guide tube can also be flushed to remove the residual water sample of the previous depth.

[0028] This reverse flushing method using filtered water sample does not need to add additional cleaning medium, is simple to operate and clean, can effectively avoid the mixing of the residual water sample of the previous depth with the newly collected water sample when collecting other depth water samples, 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.

[0029] (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.

[0030] (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 the water sample is extracted or discharged, the water flow will impact the metal ball to make it vibrate, which can effectively break the agglomerates of impurities that may be formed in the water sample, prevent the agglomeration of impurities from adhering to the inner wall of the pipeline or the surface of the threaded shaft column, and ensure the smoothness of the pipeline. At the same time, the vibration can also assist the flow of the water sample, avoiding the local flow stagnation caused by the pipeline with a wide upper part and a narrow lower part. Especially for the sticky impurities that may be contained in the mine water, the vibration can reduce the residue of the impurities in the pipeline, reduce the risk of pipeline blockage, and ensure that the 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.

[0031] (5) In the adjusting module, the inclined baffle limiting the outer wall of the sandwich column can regularize and limit the sampling guide tube wound in the storage cylinder, avoiding the messy winding and knotting of the sampling guide tube 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 the friction and wear between different parts of the guide tube and prolonging the service life of the guide tube. The inclined structure can assist in guiding the guide tube to adhere to the outer wall of the limiting sandwich column during winding, making the stored guide tube more compact, saving internal space of the storage cylinder, and adapting to the structural layout requirements of the overall device.

[0059] Specifically, when using the device for analyzing and detecting thallium element in mine water, first, the preparation work of collecting the uppermost water sample is carried out:

[0060] As shown in Figure 10 and Figure 11 , the operator first rotates the adjusting rotating plate 41 in the adjusting module 4 which is rotatably connected with the outer wall of the communication pipeline 32, since the limiting clamping layer column 43 is fixedly connected with the adjusting rotating plate 41, and the sampling guide pipe 44 inside the storage cylinder 42 is in a spiral winding state, when the adjusting rotating plate 41 is rotated, the limiting clamping layer column 43 will be rotated synchronously, and then the sampling guide pipe 44 in the storage cylinder 42 will be slowly released and stretched until the lower end of the sampling guide pipe 44 extends to the uppermost depth of the mine water, and the depth positioning of the uppermost sampling is completed.
