Description

Technical Field

[0001] This invention relates to the field of slurry sampling technology, and in particular to a gold slurry sampling and testing process. Background Technology

[0002] The refining process of gold involves multiple steps, including beneficiation, grinding, flotation, and scavenging, before finally being smelted into high-purity gold ingots. During processing, the gold ore needs to be ground into gold slurry, which is then transported through different processing equipment. In continuous production, a portion of the metal slurry needs to be retained and sampled to guide and inspect subsequent production and upstream processes.

[0003] Traditional sampling methods involve installing a discharge pipe on the surface of the gold slurry conveying pipeline. During sampling, the discharge pipe is kept open continuously. However, due to the large number of solid particles in the gold slurry and the poor mixing of its components, especially when the slurry flows slowly, severe stratification occurs within the pipeline. The discharge pipe needs to be kept open for a predetermined time, and the slurry is discharged for the predetermined time before sampling and testing the latter half of the gold slurry. This traditional sampling process and structure result in low gold slurry sampling efficiency and a significant waste of gold slurry. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a gold slurry sampling and testing process. This invention promotes the uniformity of slurry mixing within the sampling pipeline, improves the accuracy of final slurry sampling and testing, increases the efficiency of slurry sampling and testing, and reduces slurry loss.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0006] A gold slurry sampling and testing process uses a continuous gold slurry sampling device. The continuous gold slurry sampling device includes a sampling pipe, with a second guide pipe horizontally arranged at the middle of the sampling pipe. The second guide pipe has a large end and a small end. The small end of the second guide pipe is connected to a first guide pipe. The end of the first guide pipe passes through the sampling pipe and is connected to a collection box. A sampling control valve is installed between the first guide pipe and the collection box. The flow state of the first guide pipe is adjusted by the sampling control valve. The process includes the following steps: S1, according to the requirements... Assemble the first guide pipe, the second guide pipe, the sampling control valve, and the collection box in sequence. Control the second guide pipe to be horizontally positioned in the middle of the sampling pipe. S2. First, adjust the sampling control valve to be closed to control the directional flow of gold slurry in the sampling pipe. The slurry flows directionally from the small end to the large end of the second guide pipe. S3. After the gold slurry has flowed in the sampling pipe for a predetermined time, control the sampling control valve to open and close intermittently for a short period of time according to the sampling time requirements. The gold slurry flows into the collection box, achieving continuous sampling of gold slurry in the sampling pipe within a short period of time.

[0007] Preferably, the sampling control valve includes two sets of sealing gates located at the top of the collection box and slidably connected in a sealed manner. The surface of the sealing gates has a flow guide port that runs vertically through the box. The two sets of sealing gates are elastically guided and slid by an elastic guide device. The sealing gates are oscillating and controlled by a control device. Under the elastic action, the sealing gates are normally in the inner position. The control device pushes the sealing gates to move outward, controlling the flow guide port to switch to the conducting state relative to the lower end of the first flow guide pipe.

[0008] Preferably, the control device includes a control panel rotatably connected to the side wall of the collection box, a control rod fixed to the side wall of the control panel, and an L-shaped rod fixedly connected to the control panel inside the collection box, the L-shaped rod being located between two sealing gates.

[0009] Preferably, a slow telescopic rod is fixed to the outside of the first diversion pipe. The telescopic end of the slow telescopic rod extends into the inside of the first diversion pipe. The slow telescopic rod is normally in an extended state. Before the sealing gate moves inward, the slow telescopic rod is controlled to extend. Before the sealing gate moves outward to its limit position, the slow telescopic rod is in an extended state.

[0010] Preferably, the sealing gate has a vertically penetrating strip-shaped notch on its surface, the strip-shaped notch is located inside the flow guide, and a control telescopic rod is fixed to the inner wall of the strip-shaped notch. The chamber on the side of the control telescopic rod away from the telescopic end is connected to the chamber on the side of the slow telescopic rod near the telescopic end.

[0011] Preferably, the elastic guiding device includes a guide rod that penetrates the sealing gate and a spring sleeved on the outside of the guide rod. Both the control telescopic rod and the deceleration telescopic rod are elastic telescopic rods, and both the control telescopic rod and the deceleration telescopic rod are normally in the extended state. The elastic coefficient of the control telescopic rod is greater than that of the spring.

[0012] Preferably, a plurality of baffle rods are provided between the large end of the second guide pipe and the inner wall of the sampling pipe, with a gap between two adjacent baffle rods, and the plurality of baffle rods are arranged in an umbrella-like, inclined manner.

[0013] Preferably, the large end of the second guide pipe is rotatably connected to a first limiting ring, the inner wall of the sampling pipe is rotatably connected to a second limiting ring, the turbulence rod is located between the first limiting ring and the second limiting ring, and the surface of the turbulence rod is fixed with inclined turbulence blades.

[0014] Preferably, there are two sampling pipes arranged at intervals, and each sampling pipe is equipped with an on / off valve on its outer side. The on / off valves on both sides of the two sampling pipes are alternately controlled to be in the conducting state, so that the sampling and testing of gold ore slurry can be achieved by alternating the two sampling pipes.

[0015] The beneficial effects of this invention are as follows:

[0016] Compared with existing technologies, the above-mentioned structural design enables rapid sampling of slurry within the sampling pipeline within a predetermined time. By intermittently opening and closing the sampling control valve within a short period of time, rapid sampling of slurry at various locations can be achieved. The design also turbulently disperses and vibrates the slurry within the sampling pipeline, further promoting the uniformity of slurry mixing, improving the accuracy of final slurry sampling and testing, increasing the efficiency of slurry sampling and testing, and reducing slurry loss.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] See attached document Figure 1 -Appendix Figure 7 A gold slurry sampling and testing process is disclosed, which continuously transports gold slurry in a pipeline. The process utilizes a continuous gold slurry sampling device, which includes two sets of sampling pipelines 300. The first end of each sampling pipeline 300 is connected to an inlet pipeline 100, and the second end is connected to an outlet pipeline 400. Both ends of each sampling pipeline 300 are equipped with on / off valves. By controlling the conduction state of these valves, the flow of gold slurry through either sampling pipeline 300 can be controlled.

[0027] A collection box 200 is provided at the lower end of the two sampling pipes 300. The sampling pipes 300 and the collection box 200 are connected by a first guide pipe 310. A sampling control valve is provided between the sampling pipes 300 and the collection box 200. By controlling the corresponding sampling control valve to open, the gold slurry in the sampling pipes 300 passes through the corresponding first guide pipe 310 and enters the collection box 200, thereby realizing the sampling of the gold slurry in the sampling pipes 300.

[0028] The aforementioned sampling control valve includes a sealing gate 220 that is slidably and sealingly connected to the inner wall of the collection box 200. The sealing gate 220 is horizontally arranged, and a flow guide port 221 that runs vertically through the surface of the sealing gate 220 is provided. A control device 500 for controlling the movement of the sealing gate 220 is also provided on one side of the collection box 200. The control device 500 controls the sealing gate 220 to move outward, controlling the flow guide port 221 to be in communication with the lower end of the first flow guide pipe 310, thereby realizing the discharge of metal slurry. The control device 500 controls the sealing gate 220 to move inward, controlling the flow guide port 221 to be offset from the lower end of the first flow guide pipe 310. At this time, the remaining part of the sealing gate 220 presses against and seals the lower end of the first flow guide pipe 310, preventing the leakage of gold slurry.

[0029] The aforementioned sealing gate 220 and other structures are symmetrically arranged in two sets, which are respectively opposite to the two first guide pipes 310, so as to realize the opening and closing control of the lower end of the two sets of first guide pipes 310.

[0030] An annular retractable sealing structure can also be provided around the first diversion pipe 310. Two sets of annular sealing grooves adapted to the annular sealing structure can also be provided on the surface of the sealing gate 220. The first set of annular sealing grooves is located on the outer side of the upper end of the diversion port 221, and the second set of annular sealing grooves is located on the outer side of the first set of annular sealing grooves. During the sampling process, the annular sealing structure is first controlled to shrink and be offset from the second set of annular sealing grooves to ensure that the sealing gate 220 can move normally. Then, the diversion port 221 is controlled to be opposite to the first diversion pipe 310 to realize the diversion of gold slurry. During the diversion process, the annular sealing structure is controlled to extend into the first set of annular sealing grooves to increase the sealing gap distance and enhance the sealing effect.

[0031] After the slurry sampling is completed, the annular sealing structure is first controlled to shrink and offset from the sealing gate 220 to ensure that the sealing gate 220 can slide normally. Then, the sealing gate 220 is controlled to return to its initial state. At this time, the guide port 221 is offset from the first guide pipe 310, and the second set of annular sealing grooves on the surface of the sealing gate 220 is opposite to the annular sealing structure. At this time, the sampling is completed to avoid leakage of metal slurry. A raised elastic sealing gasket can be set in the annular sealing groove. The elastic sealing gasket is annular. When the annular sealing structure is not squeezed, the annular sealing gasket can return to its initial state under its own elasticity, avoiding excessive solid impurities in the slurry from remaining in the annular sealing groove and causing blockage, thus ensuring the stability of the overall sealing effect.

[0032] An elastic guide device 230 is provided between the two sets of sealing gates 220. The elastic guide device 230 can guide the two sets of sealing gates 220 and control the sealing gates 220 to elastically return to the inner side without external force. The elastic guide device 230 includes a guide rod 231 that passes through the sealing gate 220 and a spring 232 sleeved on the outside of the guide rod 231. When the sealing gate 220 is squeezed to move outward, the corresponding spring 232 is compressed to achieve the storage process. After the external force of squeezing the sealing gate 220 disappears, the sealing gate 220 returns to the initial state under the action of the spring 232. Controlling the sealing gate 220 to return to the initial inner position achieves the closure of the bottom of the first diversion pipe 310.

[0033] See attached document Figure 6 Both left and right sealing gates 220 have inner and outer sides. When the two sealing gates 220 move to the outer side, the guide port 221 can be opposite to the corresponding first guide pipe 310 to realize the guide sampling of slurry. When the two sealing gates 220 move to the inner side, the guide port 221 is offset from the corresponding first guide pipe 310. The bottom of the first guide pipe 310 is sealed by the surface of the sealing gate 220 to prevent the slurry from flowing out. During the sampling process, only one sampling pipe 300 is controlled to have slurry flow at a time, and only one corresponding sealing gate 220 is controlled to move back and forth at a time to realize intermittent or continuous sampling of metal slurry.

[0034] The aforementioned control device 500 includes a control panel 510 and a control rod 520 fixed to the outside of the control panel 510. An L-shaped rod is fixedly connected to the control panel 510 on the inner side of the collection box 200. The first side of the L-shaped rod is fixedly connected to the control panel 510, and the second side bends and extends between the two sealing gates 220. When the operator pushes or pulls the control rod 520, it causes the control panel 510 to deflect, ultimately causing the inner L-shaped rod to deflect, thus controlling the pushing of the sealing gates 220 from the middle position. The control rod 520 is normally in an attached position. Figure 4 In the vertical position shown, the control lever 520 and the L-shaped lever are in the middle position, and the sealing gates 220 on both sides are in the closed position on the inside under the action of elasticity to prevent the slurry from flowing out. During the sampling process, you only need to move the control lever 520 to deflect it towards the corresponding sampling pipe 300 side, and finally push the sealing gate 220 on the corresponding side to the outside position, so that the guide port 221 is opposite to the lower end of the first guide pipe 310 to realize the sampling of the slurry.

[0035] To achieve effective sampling of gold slurry within the sampling pipe 300, a horizontally arranged second guide pipe 320 is installed inside the sampling pipe 300. The second guide pipe 320 has a large end and a small end, with the inner diameter of the large end being larger than that of the small end. The outer surface of the second guide pipe 320 is a smooth, inclined arc-shaped surface. The second guide pipe 320 is placed horizontally in the middle of the sampling pipe 300 to minimize the impact of the slurry on the second guide pipe 320 as a whole. The slurry moves from the small end of the second guide pipe 320 towards the large end, and the small end of the second guide pipe 320 is in a connected and rotating state with the first guide pipe 310.

[0036] During the sampling process, the bottom of the first guide pipe 310 is kept in a conductive state, the pressure in the first guide pipe 310 and the second guide pipe 320 is reduced, and part of the slurry in the sampling pipe 300 enters the second guide pipe 320 and is finally discharged from the bottom of the first guide pipe 310. Depending on the sampling requirements, the first guide pipe 310 can be kept in a conductive state continuously or intermittently.

[0037] To enhance the overall support effect of the second guide pipe 320, ensure its stability within the sampling pipe 300, and improve the mixing degree of the slurry within the sampling pipe 300, thereby increasing the accuracy of sampling and testing, a first limiting ring 321 is rotatably connected to the large end of the second guide pipe 320, and a second limiting ring is rotatably connected to the inner wall of the sampling pipe 300. Several flow-dispersing rods 330 are arranged between the first and second limiting rings. The second limiting ring is larger than the first limiting ring 321. These flow-dispersing rods 330 are arranged at an angle along the slope of the outer surface of the second guide pipe 320. This structural arrangement supports and limits the large end of the second guide pipe 320 while also providing some flow-dispersing effect on the slurry. As some of the slurry flows upward, it passes through the gaps formed between the multiple flow-dispersing rods 330, colliding and mixing with each other, thus improving the mixing effect of the sampled slurry and increasing the accuracy of slurry sampling.

[0038] Inclined baffles can also be provided on the surface of the baffle bar 330 to further improve the mixing effect of the slurry flowing in the sampling pipe 300. At the same time, during the directional flow of the slurry, the baffles can impact the baffles and apply a tangential force to them, thereby driving multiple baffle bars 330 to rotate in an directional manner, further improving the mixing effect of the slurry in the sampling pipe 300 and improving the accuracy of the final slurry sampling.

[0039] All the above-mentioned sampling structures are made of wear-resistant metal materials, which can maintain normal working condition under the impact of slurry at a certain flow rate. The rotating joints and other related structures should avoid excessive gaps to prevent the entry of fine slurry particles. At the same time, the flow direction of the slurry should be adjusted and switched periodically according to the sampling time frequency, and the slurry should be controlled to pass through different sampling pipes 300 periodically. Meanwhile, the related structures in another sampling pipe 300 should be inspected and replaced to ensure the continuous, accurate and stable sampling and testing. At the same time, the flow rate and volume of the slurry in the sampling pipe 300 should be controlled at a low level to avoid instantaneous impact damage to the related structures caused by excessive flow rate and volume.

[0040] To further improve the mixing effect of the slurry within the sampling pipe 300 and enhance the accuracy of the final sampling and testing, a method of intermittent flow of slurry is adopted, where liquid is discharged from the bottom gap of the first guide pipe 310. This controls the slurry within the first guide pipe 310 and the second guide pipe 320 to be in an intermittent flow state. On the one hand, by controlling the slurry flow through these gaps, the slurry within the sampling pipe 300 is periodically disturbed, disrupting its normal flow path and promoting better mixing. On the other hand, the intermittent flow also... The method of controlling the outflow of slurry can also utilize the impact of the slurry on the inner walls of the first guide pipe 310 and the second guide pipe 320 to control the periodic vibration of the first guide pipe 310 and the second guide pipe 320. Here, the first guide pipe 310 and the second guide pipe 320 are located at a more upstream position, which can periodically vibrate the slurry that has not been fully mixed, control the slurry particles at the lower position to rise upwards, and cooperate with the subsequent directional rotating baffle bar 330 to achieve full mixing of the slurry in the sampling pipe 300.

[0041] The above-mentioned intermittent liquid discharge method can be achieved by the intermittent control sealing gate 220 reciprocating. The operator periodically swings the control rod 520 within a predetermined range on the outside. The control rod 520 drives the L-shaped rod on the inside to drive the sealing gate 220 to reciprocate, controlling the bottom gap of the first diversion pipe 310 to be in a conductive state, thereby realizing the intermittent liquid discharge of the slurry.

[0042] To further improve the control effect of liquid discharge from the slurry gap, the surface of the sealing gate 220 is also provided with a strip-shaped notch on the inner side. The strip-shaped notch is equipped with a control telescopic rod 210. The telescopic end of the control telescopic rod 210 is fixed with an arc-shaped limiting block 211. When both sealing gates 220 are located on the inner side, a virtual circumferential limiting area 2001 is formed between the two limiting blocks 211 to limit the L-shaped rod. While swinging the control rod 520, it can drive the L-shaped rod to move back and forth, realizing the reciprocating control of the sealing gate 220 on either side.

[0043] It should be noted that the reciprocating swing control lever 520 needs to be controlled on either the left or right side to avoid excessive swing amplitude affecting the position of the sealing gates 220 on both sides.

[0044] A slow-moving telescopic rod 311 is also provided on the outside of the first guide pipe 310. The telescopic end of the slow-moving telescopic rod 311 extends into the first guide pipe 310. By controlling the extension of the telescopic end of the slow-moving telescopic rod 311, an obstruction can be formed in the first guide pipe 310 to reduce the flow rate of the slurry in the first guide pipe 310. By controlling the contraction of the telescopic end of the slow-moving telescopic rod 311, the flow area of ​​the slurry in the first guide pipe 310 increases and the flow rate increases. By periodically controlling the extension of the telescopic end of the slow-moving telescopic rod 311, the flow rate of the slurry in the first guide pipe 310 can be controlled. While the slurry drives the first guide pipe 310 and the second guide pipe 320 to vibrate periodically, the flow rate of the slurry can be adjusted to meet the required control effect.

[0045] Meanwhile, the chamber on the side of the control telescopic rod 210 away from the telescopic end is connected to the chamber on the side of the slow telescopic rod 311 near the telescopic end. Both the control telescopic rod 210 and the slow telescopic rod 311 are elastic telescopic rods, and both are equipped with control oil. By adjusting the contraction of the control telescopic rod 210, the control oil can be squeezed into the slow telescopic rod 311, controlling the slow telescopic rod 311 to contract synchronously, thereby realizing the adjustment and control of the extension and contraction state of the slow telescopic rod 311.

[0046] It should be noted that both the slow telescopic rod 311 and the control telescopic rod 210 are normally in the extended state. The extended state of the slow telescopic rod 311 can obstruct the slurry in the first guide pipe 310, so as to avoid the excessive flow velocity of the slurry in the first guide pipe 310 during the movement of the sealing gate 220, which would cause excessive impact on the sealing gate 220 and affect the normal movement and sealing of the sealing gate 220.

[0047] It should also be noted that the elastic coefficient of the control telescopic rod 210 is greater than that of the spring 232. That is, during the synchronous movement of the control telescopic rod 210 and the sealing gate 220 by the L-shaped rod, the spring 232 is compressed before the control telescopic rod 210, and the sealing gate 220 moves to the outward position. During this process, the slow telescopic rod 311 remains extended to reduce the flow rate of the slurry in the first diversion pipe 310 and avoid excessive impact on the sealing gate 220 during the movement. After reaching the extreme position on the side, the bottom of the first guide pipe 310 is opposite to the limit block 211, and the sealing gate 220 is blocked by the limit block 211 and cannot move further. At this time, the L-shaped rod is pushed inward by the control panel 510. At this time, the compression control telescopic rod 210 continues to compress, and the control oil in the control telescopic rod 210 is squeezed into the slow telescopic rod 311, causing the slow telescopic rod 311 to contract. The obstruction of the first guide pipe 310 disappears, and the flow rate of the slurry in the first guide pipe 310 increases, so as to improve the detection amount of slurry sampling.

[0048] Meanwhile, during the sampling process, the extension and retraction of the end of the slow telescopic rod 311 can be periodically controlled to adjust the flow rate of the slurry in the first guide pipe 310. The variable speed slurry impacts the inner walls of the first guide pipe 310 and the second guide pipe 320, causing the slurry in the sampling pipe 300 to vibrate and improving the mixing effect of the slurry in the sampling pipe 300.

[0049] After sampling, the L-shaped rod is controlled by the control panel 510 to move in the reverse direction inward. During this process, the control telescopic rod 210, which has a larger elastic coefficient, extends first, and the extension end of the slow telescopic rod 311 extends synchronously. Before the sealing gate 220 moves, the flow rate of the slurry in the first guide pipe 310 is reduced to avoid excessive impact on the sealing gate 220 during its inward movement. After the control telescopic rod 210 extends and returns to its initial state, the spring 232 pushes the sealing gate 220 to move inward. The guide port 221 is offset from the bottom of the first guide pipe 310, thus sealing the bottom of the first guide pipe 310, preventing the slurry from continuously flowing out, and ensuring stable slurry delivery.

[0050] This article uses gold ore slurry as an example for illustration. Those skilled in the art can also use the technical concept of this invention to sample and test different types of ore slurry.
