Description

Technical Field

[0001] The invention relates to the technical field of metallurgical sample detection, and in particular to an automatic detection system for metallurgical samples. Background Art

[0002] Tungsten is a metal element. In nature, tungsten mainly exists as a hexavalent cation. Due to its small ionic radius, high electric charge, strong polarization ability, and easy formation of complex anions, tungsten mainly combines with cations such as Fe2+, Mn2+, and Ca2+ in the solution in the form of complex anions to form wolframite or scheelite precipitation.

[0003] In the metallurgical production of metallic tungsten, due to the brittleness of tungsten minerals, a large amount of tungsten fine mud with a particle size of less than 74μm will be produced during the mining, crushing and beneficiation process, resulting in a complex mineral particle size composition in the tungsten ore metallurgical process. If the tungsten fine mud in the metallurgical process is not detected and screened out, the purity of the metal tungsten produced by the metallurgical process will be reduced, resulting in poor hardness and wear resistance. In the actual metallurgical production process, the detection of the leached sodium tungstate solution has a certain lag, and the flow production of the entire metallurgical production line is continuous. The overall metallurgical production efficiency will be reduced when sampling and waiting for the test results. If unqualified materials are detected during the production process, in order to deal with the metallurgical waste containing tungsten fine mud, more complex processes and higher costs may be required, including additional screening, washing and recovery steps, as well as waste treatment costs, which greatly increases the metallurgical production cost of tungsten.

It should be noted that: the sampling adapter tube 1 is assembled and fixed with the infusion pipes 3 at both ends (that is, the sampling adapter tube 1 is installed on the existing infusion pipe 3 for sampling). When the sodium tungstate solution needs to be continuously transported through the infusion pipe 3 during the metallurgical process, when the high-pressure sodium tungstate solution reaches the front end of the sampling adapter tube 1, the sodium tungstate solution will impact the impeller 8, so that the impeller 8 continues to rotate, and the sodium tungstate solution is stirred, so that the flowing liquid rotates under the action of the rotating impeller 8 to generate centrifugal force, thereby exerting a centrifugal force on the particulate impurities in the solution.

After the sampling is completed, the hydraulic push rod 20 drives the adjustment rack 19 to move down and reset, and the adjustment gear ring 18 will drive the sampling tube 10 to rotate to the initial tilted state. At this time, the spoiler 13 is not positively pressurized, and the pressure on it is reduced, and it is reset under the push of the balanced telescopic rod 14, so that the sampling slot on the sampling tube 10 is closed; Based on the above advantages, the baffle 13 can be adjusted to be subjected to the impact water pressure in the positive direction, the sampling slot on the sampling tube 10 can be opened, and the solution at the inner edge and the axis of the sampling transfer tube 1 can be sampled respectively, so as to facilitate the subsequent detection and analysis of the sampled materials at different parts; Two fan-shaped plates 25 are fixedly connected to the top of the classification detection cylinder 2, a driving motor 21 is arranged below the classification detection cylinder 2, the output end of the driving motor 21 is connected to a plurality of partitions 23 through a driving shaft 22, a titration liquid storage box 26 is arranged above the partition 23, a sealing circular plate 24 is connected to the bottom end of the partition 23, a plurality of through holes are opened on the sealing circular plate 24, and a through valve assembly for discharging the liquid after the test is connected to the inner side wall of the through hole; Furthermore, the bottom end of the classification detection cylinder 2 is fixedly connected to a liquid collecting cylinder 35 through a layered plate 34, the bottom end of the liquid collecting cylinder 35 is fixedly connected to a base 36, the side wall of the driving motor 21 is fixedly connected to the bottom end of the layered plate 34, a protective cover is arranged outside the driving motor 21, and the output end of the driving motor 21 is fixedly connected to the sealing circular plate 24 and a plurality of partitions 23 through a driving shaft 22, and the number of the partitions 23 is six, which divides the interior of the classification detection cylinder 2 into six sector-shaped spaces, and the through hole is located at the bottom of the sector-shaped space separated by two partitions 23, and the titration liquid storage box 2 6 is fixedly connected with a control valve 27 at the bottom, and two valve ports are provided on the control valve 27.

An electromagnetic ring 32 is provided on the outer wall of the top end of the Z-shaped tube 33. It should be noted that: after the two groups of sampled sodium tungstate solutions flow into the classification detection cylinder 2, they will be separated by the partition 23 respectively, and then the driving motor 21 is started to drive the sealing circular plate 24 and the multiple partitions 23 to rotate through the driving shaft 22 respectively, and the rotation is controlled to stop after 60°, so that the sampled solution enters the position of the next fan-shaped space.

This detection process is a prior art and will not be described in detail here. It can be known that the sampling transfer tube 1 is located Whether the sodium tungstate solution sampled from the inner edge contains tungsten fine mud or other particulate impurities, as well as the content and concentration of the sodium tungstate solution at the axial position, after the detection is completed, the driving motor 21 is used to control the rotation of 60° again and then stop. At this time, the docking tube 31 will rotate to the docking hole of the layered plate 34. At this time, the electromagnetic ring 32 is energized to make it magnetic and generate magnetic repulsion to the magnetic seat 29. The magnetic seat 29 will drive the valve cover 28 to move up to open the through hole, allowing the tested liquid to flow into the liquid collecting cylinder 35 through the Z-shaped tube 33 for subsequent centralized treatment; The above benefits are: in this way, the detection of the two groups of sodium tungstate solutions can be completed quickly, so that the sampling detection has a control group, ensuring that the sampling detection results of the leached sodium tungstate solution are more comprehensive and accurate; When the present invention is used, the sampling adapter tube 1 is assembled and fixed with the infusion pipelines 3 at both ends (that is, the sampling adapter tube 1 is installed on the existing infusion pipeline 3 for sampling). When the sodium tungstate solution needs to be continuously transported through the infusion pipeline 3 during the metallurgical process, when the sodium tungstate solution with medium and high pressure reaches the front end of the sampling adapter tube 1, the sodium tungstate solution will impact the impeller member 8, so that the impeller member 8 rotates continuously, and the sodium tungstate solution is stirred, and the flowing liquid is rotated under the action of the rotating impeller member 8 to generate centrifugal force, thereby exerting a centrifugal force on the particulate impurities in the solution. If the sodium tungstate solution at this time contains tungsten fine mud particles, the tungsten fine mud particles will move and gather at the edge of the inner wall of the sampling adapter tube 1 under the action of centrifugal force.

Then, the driving motor 21 is started to drive the sealing circular plate 24 and the multiple partitions 23 to rotate through the driving shaft 22 respectively. The control rotation is stopped after 60°, so that the sampled solution enters the position of the next fan-shaped space. At this time, the control valve 27 is controlled to open, and the detection liquid in the titration liquid storage box 26 is respectively passed into the two groups of sodium tungstate solutions. This detection process is a prior art and will not be described in detail here. It can be known whether the sodium tungstate solution sampled at the inner edge of the sampling transfer tube 1 contains tungsten fine mud or other particulate impurities, as well as the axial position. After the content and concentration of the sodium tungstate solution are detected, the driving motor 21 is used to control the rotation of 60° again and then stop. At this time, the docking tube 31 will rotate to the docking hole of the layered plate 34. At this time, the electromagnetic ring 32 is energized to make it magnetic and generate magnetic repulsion to the magnetic seat 29. The magnetic seat 29 will drive the valve cover 28 to move up to open the through hole, allowing the tested liquid to flow into the liquid collecting cylinder 35 through the Z-shaped tube 33 for subsequent centralized processing. In this way, the detection of the two groups of sodium tungstate solutions sampled can be quickly completed, so that the sampling detection has a control group, ensuring that the sampling detection results of the leached sodium tungstate solution are more comprehensive and accurate.
