Description

Technical Field

[0001] This invention relates to the field of metal detection technology, specifically to a precious metal detection and analysis device. Background Technology

[0002] The physicochemical properties of precious metals determine their important role in industries and high-tech sectors, making it urgent to explore new ways to increase precious metal resources. Lead deposits are hydrothermal deposits with many associated elements. In particular, after the lead ore undergoes flotation, precious metals and other elements are further enriched and enter the lead concentrate. With the development of analytical techniques, the analysis of precious metal elements, especially platinum group elements, mainly adopts inductively coupled plasma mass spectrometry (ICP-MS). The working principle is to first atomize the sample solution to form an aerosol. After the aerosol comes into contact with and mixes with argon gas, argon gas is used as a carrier gas to carry the aerosol into the central plasma channel in the form of a high-speed gas flow. The high-temperature ICP-MS ionizes the precious metal atoms. Then, the mass analyzer separates and detects the ions according to their mass-to-charge ratio. Finally, by comparing the ion intensity with the standard sample, qualitative and quantitative analysis of precious metal elements can be achieved.

[0003] However, the existing technology has the following problems:

[0004] In the sample introduction stage of existing technologies, when argon gas is used as a carrier gas and comes into contact with aerosols, the argon gas is usually directly introduced through a single pipe. When introduced through a single pipe, the argon gas flow path is fixed, which easily leads to laminar or weakly turbulent flow. Under laminar flow conditions, the argon gas mainly moves horizontally along the flow direction, with poor lateral diffusion. The argon gas flows directly through the mixing chamber in an aggregated manner, which may cause stratification between the argon gas and the surrounding aerosols. This prevents the argon gas from mixing quickly with the surrounding aerosols, resulting in uneven mixing between the argon gas and the aerosols. Consequently, the aerosols carried by the argon gas during transportation have uneven texture, resulting in uneven distribution of aerosols entering the plasma. This leads to fluctuations in parameters such as local temperature and electron density, disrupting the internal equilibrium of the plasma, and thus affecting the stability of the plasma, ultimately affecting the detection results. Summary of the Invention

[0005] The purpose of this invention is to provide a precious metal detection and analysis device to solve the above-mentioned problems. It aims to overcome the shortcomings of the prior art where argon gas is directly introduced into the mixing chamber through a single pipe and flows directly through the mixing chamber in an aggregated manner, which may cause stratification between the argon gas and the surrounding aerosols, resulting in the argon gas not being able to mix quickly with the surrounding aerosols.

[0017] 1. This precious metal detection and analysis equipment, through the cooperation of the mixing component and the atomizing component, enables the argon gas to be dispersed into multiple fine airflows through the multiple pores of the mixing tube in conjunction with the air inlet hood. As the multiple pores rotate continuously, the argon gas enters the mixing tube through the multiple pores and comes into contact with the aerosol, thereby increasing the contact area between the argon gas and the aerosol and avoiding the local accumulation of argon gas. The setting of two flow dividers allows the two flow dividers to divert the argon gas flowing out of the air inlet tube by continuously swinging up and down, avoiding the direct impact of some argon gas on local pores and causing uneven air intake among the multiple pores.

[0018] 2. This precious metal detection and analysis equipment, through the setting of the stirring section, enables multiple blades to form a swirling flow inside the mixing tube when the mixing tube rotates, thereby promoting the mixing of argon and aerosol in the mixing tube; through the cooperation of the sliding sleeve, rotating shaft and wave ring, the sliding sleeve can use the power generated by the extension and contraction to drive the rotating shaft to rotate back and forth, causing the blades to oscillate back and forth. Multiple blades play a turbulent role through reciprocating oscillation, further promoting the mixing efficiency of argon and aerosol.

[0019] 3.

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0035] Please see Figure 1 - Figure 4 A precious metal detection and analysis device includes a main unit 1, a mass analyzer 2 installed inside the main unit 1, a plasma chamber and a detection instrument inside the mass analyzer 2. The plasma chamber and detection instrument inside the mass analyzer 2 are existing technologies, and their specific structures and working principles are not detailed here. An exhaust pipe 3 is connected to the mass analyzer 2. The device also includes an atomizing component 4 for atomizing the sample solution into an aerosol. The atomizing component 4 includes a liquid hopper 41, which is installed on the main unit 1, and a bottom connection is made to... Liquid tube 42 is located inside the main unit 1. A bend 43 is connected to the bottom of the liquid tube 42. A connector 44 is connected to the outer wall of the liquid tube 42. An atomizer 45 is connected to the connector 44. The atomizer 45 is connected to the end of the bend 43 away from the liquid tube 42. The sample solution is poured into the liquid hopper 41 and enters the liquid tube 42 through the liquid hopper 41. The bend 43 delivers the sample solution to the atomizer 45. The atomizer 45 uses ultrasonic atomization technology to atomize the sample solution to form an aerosol.

[0036] Furthermore, please refer to Figure 2 - Figure 5The mixing component 5 is used to divide argon gas into multiple fine gas streams for contact with the aerosol. The mixing component 5 includes a mixing tube 52, which is rotatably disposed inside the main unit 1. One end of the mixing tube 52 is connected to the atomizing component 4, and the other end is connected to the mass analyzer 2. An air inlet hood 54 is fixedly connected inside the main unit 1 and is fitted onto the end of the mixing tube 52 near the atomizing component 4. An air inlet pipe 55 is connected to the top of the air inlet hood 54. A gear 57 is disposed inside the main unit 1 above the mixing tube 52. A gear ring 58 is fixedly connected to the outer wall of the mixing tube 52, and the gear 57 meshes with the gear ring 58. Multiple air holes are opened on the mixing tube 52, and all air holes on the mixing tube 52 are located inside the air inlet hood 54. The air inlet hood 54 is rotatably connected to the outer wall of the mixing tube 52. The mass analyzer 2 is provided with an inlet and an exhaust pipe 3 is connected to the mass analyzer 2. One end of the mixing tube 52 is rotatably connected to the inlet of the mass analyzer 2. The end of the mixing tube 52 away from the mass analyzer 2 is rotatably connected to the atomizer 45. The air inlet tube 55 passes through the main unit 1. Two rotating frames 51 and two fixed frames 53 are fixedly installed inside the main unit 1. The mixing tube 52 is rotatably installed inside the main unit 1 through the two rotating frames 51. The air inlet hood 54 is fixedly installed inside the main unit 1 through the two fixed frames 53. A motor 56 is installed inside the main unit 1. A gear 57 is fixedly connected to the output end of the motor 56. The motor 56 drives the gear ring 58 to rotate through the gear 57. The gear ring 58 drives the mixing tube 52 to rotate on the two rotating frames 51. Multiple air holes are opened on the mixing tube 52. All air holes on the mixing tube 52 are located inside the air inlet hood 54. Argon gas in the air inlet hood 54 enters the mixing tube 52 through the multiple air holes of the mixing tube 52. The multiple air holes separate the argon gas into multiple fine airflows, so that the multiple fine airflows come into contact with the aerosol at multiple angles, thereby increasing the contact area between the argon gas and the aerosol.

[0037] Argon gas enters the inlet hood 54 through the inlet pipe 55. As the mixing tube 52 rotates, the positions of multiple vents inside the inlet hood 54 change continuously, causing the angle at which the argon gas enters the mixing tube 52 to also change continuously. This allows the argon gas to continuously enter the mixing tube 52 at multiple angles and points, minimizing the local accumulation of argon gas in the mixing tube 52, thereby optimizing the mixing efficiency and ensuring the stability of the plasma. Through the cooperation of the mixing component 5 and the atomizing component 4, the multiple vents of the mixing tube 52, in conjunction with the inlet hood 54, allow the argon gas to be dispersed into multiple fine gas flows. As the multiple vents rotate continuously, the argon gas enters the mixing tube 52 through multiple vents and comes into contact with the aerosol, thereby increasing the contact area between the argon gas and the aerosol and also preventing the local accumulation of argon gas.

[0038] Furthermore, please refer to Figure 6 - Figure 7The inner wall of the air intake hood 54 is hinged with two flow dividers 59, which are mirror images of each other. Both flow dividers 59 are located below the air intake pipe 55. The two flow dividers 59 can divert the argon gas entering the air intake hood 54 from the air intake pipe 55, so that the argon gas enters multiple pores evenly and avoids some argon gas concentrating and impacting the pores located below the air intake pipe 55. The bottom of the flow divider 59 is connected to a contact rod 510. The outer wall of the mixing pipe 52 is connected to multiple arc-shaped blocks 511, which are located inside the air intake hood 54. When the multiple arc-shaped blocks 511 move, they slide and contact the contact rod 510 in sequence. When the multiple arc-shaped blocks 511 rotate with the mixing pipe 52, they can also use the two contact rods 510 to drive the two flow dividers 59 to swing up and down continuously. The two flow dividers 59 can disturb the airflow and further disperse the argon gas, so that the argon gas enters multiple pores more evenly.

[0039] In addition, please see Figure 2 , Figure 6 - Figure 9 The mixing component 5 also includes a stirring part 6, which is located at the end of the mixing tube 52 away from the atomizing component 4. The stirring part 6 includes two sets of rotating shafts 64, both of which are rotatably connected to the mixing tube 52. Each set of rotating shafts 64 consists of multiple shafts, which are arranged in a circumferential array on the mixing tube 52. One end of the rotating shaft 64 located inside the mixing tube 52 is fixedly connected to a blade 67. The rotating shaft 64 drives the blade 67 to revolve around the axis of the mixing tube 52. The blade 67 has an inclined angle, and the multiple blades 67 in the same set are arranged in a spiral shape. When the multiple blades 67 revolve, they can form a swirling flow inside the mixing tube 52, thereby promoting the mixing of aerosol and argon.

[0040] In addition, please see Figure 8 - Figure 9The stirring unit 6 also includes two connecting frames 61, both of which are fixedly connected to the main unit 1. Two wave rings 62 are fixedly connected between the two connecting frames 61. A sliding sleeve 63 is movably connected to the outer wall of the rotating shaft 64. The sliding sleeves 63 on the two sets of rotating shafts 64 are slidably connected to the inner sides of the two wave rings 62 respectively. The inner side of the wave rings 62 forms multiple raised arc surfaces. The sliding sleeves 63 are limited by the wave rings 62 and cannot rotate, so that the sliding sleeves 63 on the rotating shaft 64 slide on the inner side of the wave rings 62 as the rotating shaft 64 revolves. This causes the sliding sleeves 63 to continuously extend and retract on the rotating shaft 64. A spring 66 is connected between the rotating shaft 64 and the sliding sleeves 63. The 6 can provide elasticity when the sliding sleeve 63 extends, thereby reducing the wear of the sliding connection between the sliding sleeve 63 and the wave ring 62. The rotating shaft 64 is provided with an annular groove 65, and the inner wall of the sliding sleeve 63 is provided with balls. The balls of the sliding sleeve 63 are slidably connected with the annular groove 65. When the sliding sleeve 63 extends or retracts, the balls on the sliding sleeve 63 slide in the annular groove 65, so that the annular groove 65 is driven by the counter thrust of the balls to drive the rotating shaft 64 to reciprocate. The rotating shaft 64 drives the blades 67 to reciprocate, so that multiple blades 67 can also reciprocate while following the revolution of the mixing tube 52, which can play a turbulence role and further promote the mixing efficiency of argon and aerosol.

[0041] It is worth noting that, please refer to Figure 2 , Figure 10 - Figure 12It also includes a fusion assembly 7, which is disposed on one side of the atomizing assembly 4 and is used to grind the incompletely dissolved solute in the sample solution. The fusion assembly 7 includes a cam 71, a gantry frame 72, a rotating rod 73, a sliding shaft 74, two levers 75, a rotating ring 76, a lever 77, and multiple scrapers 78. The cam 71 is fixedly connected to the outer wall of the mixing tube 52 near 43. The gantry frame 72 is slidably connected to the connecting seat 44. When moving, the cam 71 slides in contact with the inner side of the gantry frame 72. The rotating rod 73 is rotatably connected to the outer wall of the liquid tube 42. The sliding shaft 74 is connected to one end of the rotating rod 73. Both levers 75 are connected to the other end of the rotating rod 73. The top of the gantry frame 72 is provided with a sliding groove. The sliding shaft 74 is slidably connected to the sliding groove of the gantry frame 72. The rotating ring 76... 6. Rotary mounting is installed on the inner wall of liquid pipe 42. A lever 77 is fixedly connected to the outer wall of rotating ring 76. The lever 77 is slidably connected to liquid pipe 42. The lever 77 is located between two pivot shafts 75. When cam 71 rotates, it drives gantry frame 72 to move back and forth. The gantry frame 72 drives rotating rod 73 to swing back and forth through the cooperation of sliding groove and sliding shaft 74. When rotating rod 73 swings back and forth, it drives rotating ring 76 to rotate back and forth through the cooperation of two pivot shafts 75 and lever 77. Multiple scraper strips 78 are fixedly connected to rotating ring 76. Multiple scraper strips 78 slide in contact with the inner wall of liquid pipe 42. Rotating ring 76 drives multiple scraper strips 78 to rotate back and forth inside liquid pipe 42. When multiple scraper strips 78 move, they continuously scrape the inner wall of liquid pipe 42, scraping off the solute attached to the inner wall of liquid pipe 42.

[0042] It is worth noting that, please refer to Figure 11 - Figure 12 The fusion assembly 7 also includes a grinding block 79 and a drain block 710. The grinding block 79 is rotatably connected to the inner wall of the liquid tube 42 and is fixedly connected to the bottom ends of multiple scrapers 78. The drain block 710 is fixedly connected to the inner wall of the liquid tube 42, and a grinding layer is formed between the top surface of the drain block 710 and the bottom surface of the grinding block 79. The drain block 710 is located above the bend 43. The grinding block 79 is provided with multiple through grooves, and the drain block 710 is provided with multiple drain holes. When the multiple scrapers 78 reciprocate, they drive the grinding block 79 to reciprocate, and the sample solution in the liquid tube 42... The sample solution first falls through multiple slots on the grinding block 79 onto the drain block 710. Then, it drips through multiple holes in the drain block 710 into the bent tube 43. The solute particles in the sample solution cannot pass through the holes, so they remain temporarily in the grinding layer between the top surface of the drain block 710 and the bottom surface of the grinding block 79. The grinding block 79 can grind the solute particles in the grinding layer by reciprocating rotation, breaking them into smaller particles, thereby accelerating the dissolution of the solute and preventing the solute particles from clogging the atomizer 45 and affecting the atomization effect.

[0043] Using the above structure, the working principle of this case is as follows: the plasma chamber and detection instruments in the mass analyzer 2 are all existing technologies, and their specific structures and working principles will not be elaborated here. The sample solution is poured into the liquid hopper 41, and the sample solution enters the liquid tube 42 through the liquid hopper 41. The bent tube 43 transports the sample solution to the nebulizer 45. The nebulizer 45 uses ultrasonic nebulization technology to atomize the sample solution into an aerosol. The aerosol enters the mixing tube 52, and argon gas enters the inlet hood 54 through the inlet pipe 55. The argon gas in the inlet hood 54 enters the mixing tube 52 through multiple pores in the mixing tube 52. The multiple pores atomize the argon gas... The gas is separated into multiple fine gas streams, which come into contact with the aerosol at multiple angles, thereby increasing the contact area between argon and aerosol and accelerating the mixing efficiency. After the motor 56 is started, the motor 56 drives the gear ring 58 to rotate through the gear 57. The gear ring 58 drives the mixing tube 52 to rotate on the two rotating frames 51. The positions of multiple gas holes inside the gas inlet hood 54 are constantly changing, so that argon can continuously enter the mixing tube 52 at multiple angles and points, minimizing the local accumulation of argon in the mixing tube 52, thereby optimizing the mixing efficiency and ensuring the stability of the plasma.

[0044] Two flow dividers 59 can divert the argon gas entering the intake hood 54 from the intake pipe 55. After diversion, the argon gas enters multiple gas holes evenly. When the mixing pipe 52 rotates, it drives multiple arc blocks 511 to rotate. When the arc blocks 511 rotate, they contact the contact rod 510 and apply an upward thrust to the contact rod 510, causing the contact rod 510 to drive the flow dividers 59 to swing upward. When the arc blocks 511 are not in contact with each other, the flow dividers 59 swing down to reset using the airflow pressure. This allows the multiple arc blocks 511 to continuously swing up and down with the two contact rods 510 while rotating with the mixing pipe 52. The two flow dividers 59 can disturb the airflow and further disperse the argon gas, allowing the argon gas to enter the multiple gas holes more evenly.

[0045] When the mixing tube 52 rotates, it drives two sets of rotating shafts 64 to rotate. The rotating shafts 64 drive the blades 67 to revolve around the axis of the mixing tube 52. When the multiple blades 67 revolve, they can form a swirling flow inside the mixing tube 52, thereby promoting the mixing of aerosol and argon. Taking one of the wave rings 62 as an example, multiple raised arc surfaces are formed on the inner side of the wave ring 62, so that the sliding sleeve 63 on the rotating shaft 64 slides on the inner side of the wave ring 62 as the rotating shaft 64 revolves. The sliding sleeve 63 continuously extends and retracts on the rotating shaft 64. The spring 66 can provide elastic force when the sliding sleeve 63 extends, thereby reducing the wear of the sliding connection between the sliding sleeve 63 and the wave ring 62. When the sliding sleeve 63 extends or retracts, the balls on the sliding sleeve 63 slide in the annular inclined groove 65, causing the annular inclined groove 65 to be driven by the counter-thrust of the balls, which drives the rotating shaft 64 to reciprocate. The rotating shaft 64 drives the blades 67 to reciprocate, so that multiple blades 67 can also reciprocate while following the revolution of the mixing tube 52. The reciprocating oscillation of multiple blades 67 can play a turbulence role, further promoting the mixing of aerosol and argon in the mixing tube 52. After the argon and aerosol are mixed, they enter the plasma chamber through the inlet of the mass analyzer 2. After plasma treatment, they are detected and analyzed by the detection instrument. The exhaust gas is discharged through the exhaust pipe 3.

[0046] During sample solution preparation, a small amount of incompletely dissolved solute may remain. Some of this solute, after entering the liquid tube 42, will adhere to the inner wall of the tube. Over time, scale may form on the inner wall of the liquid tube 42, affecting its performance. When the mixing tube 52 rotates, it drives the cam 71 to rotate. The cam 71 alternately contacts the two sides of the inner side of the portal frame 72, causing the portal frame 72 to move back and forth. The portal frame 72, through the cooperation of the sliding groove and the sliding shaft 74, drives the rotating rod 73 to swing back and forth. The swinging rod 73, through the cooperation of the two pivot shafts 75 and the pivot rod 77, drives the rotating ring 76 to rotate back and forth. The rotating ring 76 drives multiple scraper blades 78 to rotate back and forth within the liquid tube 42. During this movement, the multiple scraper blades 78 continuously scrape the liquid tube. The inner wall of the liquid tube 42 is scraped off to remove the solute adhering to the inner wall of the liquid tube 42, preventing the solute from adhering to the liquid tube 42. When multiple scrapers 78 rotate back and forth, they drive the grinding block 79 to rotate back and forth. The sample solution in the liquid tube 42 first falls through multiple grooves on the grinding block 79 to the drain block 710. The sample solution drips through multiple holes in the drain block 710 into the bent tube 43. The solute particles contained in the sample solution cannot pass through the holes, so that the solute particles are temporarily left in the grinding layer between the top surface of the drain block 710 and the bottom surface of the grinding block 79. The grinding block 79 can grind the solute particles in the grinding layer by reciprocating rotation, breaking the solute particles into smaller particles, thereby accelerating the dissolution of the solute and preventing the solute particles from clogging the atomizer 45 and affecting the atomization effect.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
