Description

Technical Field

[0001] The invention relates to the technical field of carbon extraction, in particular to a combined extraction device for gold-loaded carbon in a carbon slurry process. Background Art

[0002] The carbon-in-pulp process is an extraction technology widely used in gold mines, mainly used to recover gold from gold-containing ores or tailings.

[0003] In the carbon-in-slurry process, the recovery of gold ore slurry is mainly reflected in the recovery and extraction of gold-loaded carbon in the carbon slurry. In the prior art, a Chinese patent document with application publication number CN202010757575.3 records a combined extraction device for gold-loaded carbon in the carbon-in-slurry process, and discloses the combined extraction device for gold-loaded carbon:

[0004] It includes a spiral cylindrical screen, a charcoal extractor, a charcoal slurry tank, a slurry collecting tank, a spray pipe, a vibrating screen and a charcoal storage tank. The charcoal slurry tank is provided with a charcoal slurry inlet pipe and the charcoal slurry inlet pipe is connected to the charcoal slurry tank. The charcoal extractor is provided in the charcoal slurry tank. The charcoal extractor is provided with an air supply pipe. The input end of the charcoal extractor is arranged at the bottom of the inner cavity of the charcoal slurry tank. The output end of the charcoal extractor is connected to the input port of the spiral cylindrical screen through the charcoal extracting pipe. The output port of the spiral cylindrical screen is provided with a transport pipe. The present invention separates the gold-loaded charcoal and the slurry in advance through the spiral cylindrical screen. The slurry returns to the charcoal slurry tank, and the gold-loaded charcoal enters the vibrating screen, which speeds up the charcoal extraction speed. After that, the surface of the gold-loaded charcoal is cleaned in all directions by using the high-pressure first spray head and the second spray head, which ensures the quality of the gold-loaded charcoal and improves the efficiency of gold-loaded charcoal extraction and the quality of the output.

[0005] It is common to find gold-loaded carbon extraction devices like the one disclosed in the above patent documents. Since the carbon slurry is filtered and extracted based on the radial flow of the cylindrical screen, such devices are not limited to the cylindrical type. There are also bridge-type and chute-type extraction devices, which are similar to the principle of runoff type. In the process of carbon slurry extraction, the gold-loaded carbon has a large contact degree with the screen, and there is a certain resistance to the flow of the gold-loaded carbon. Correspondingly, the wear rate of the carbon is also relatively high, resulting in more fine-grained gold-loaded carbon being lost with the carbon slurry, causing excessive loss of gold. For this reason, we propose a combined extraction device for gold-loaded carbon in a carbon slurry process. Summary of the invention

[0006] 1. Technical issues to be resolved

[0025] Preferably, an inner plate is provided on the inner side of the filter screen, and the inner plate is spiral-shaped as a whole. The inner plate is also fixed to the output end of the driving mechanism thereon, and the driving mechanism drives the inner plate to rotate relative to the axial direction of the filter screen.

The number of limit slots corresponds to the pluggable rotation angle of the second latch based on the connecting plate. In order to ensure the good docking of the second latch and the limit slot in the subsequent connection, it is necessary to select a servo motor as the motor. By using the programmability of the servo motor, the second latch can be aligned with the limit slot after the base plate rotates a full circle.

[0033] (III) Beneficial effects

[0034] Compared with the prior art, the present invention provides a combined extraction device for gold-loaded carbon in a carbon slurry process, which has the following beneficial effects:

[0035] The combined extraction device for gold-loaded carbon in a carbon slurry process has an extraction component, and under the driving action of the driving mechanism on the impeller, the cutting surface is small due to the structure of the impeller. During the rotation of the impeller, the carbon slurry can be ensured to flow quickly while the wear on the gold-loaded carbon is minimized. Figure 7In the structural state shown, the thrust generated by the impeller is to move the carbon slurry inside the carbon can along the axial direction of the filter screen. Because it is an axial flow type and is used in combination with a truncated cone-shaped filter screen, on the one hand, the resistance is small, and on the other hand, because the carbon slurry is inclined to wash the outer wall of the filter screen, the wear rate of the gold-loaded carbon is also lower;

[0036] Furthermore, because the filter screen is coaxial with the carbon canister, the filter screen can be set up to the maximum extent based on the carbon canister. Under the premise of the same carbon slurry flow rate, the extraction efficiency of the gold-loaded carbon can be maximized. Relatively speaking, under the premise of ensuring the original extraction efficiency, the overall footprint of the extraction device can be further reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0082] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Specific embodiment 1

[0084] In order to address the shortcomings of the existing technology, such as Figures 1 to 5 As shown, the present invention provides a combined extraction device for gold-carrying carbon in a carbon slurry process, wherein a carbon canister 1 is provided with at least one material pipe 3 for inputting carbon slurry or chemical agents, and according to actual use requirements, a carbon extraction pump 6 is also provided inside the carbon canister 1, and the carbon extraction pump 6 is connected and communicated with one material pipe 3;

[0085] The material pipe 3 is fixedly connected to the carbon canister 1 based on the canister cover 2 .

[0086] It should be noted that in the gold extraction process of carbon slurry, in the process of extracting gold-loaded carbon from the carbon slurry, the carbon slurry enters the interior of the carbon canister 1 through the material pipe 3, and on the outside of the extraction component 5, the main body of the extraction component 5 is relatively rotated inside the carbon canister 1 based on the axial direction of the carbon canister 1. In this process, the carbon slurry flows from the outside of the main body of the extraction component 5 to the inside thereof, and the gold-loaded carbon is filtered and extracted through the extraction component 5. The gold-loaded carbon remains inside the carbon canister 1, and the filtered carbon slurry is discharged from the inside of the extraction component 5 through the discharge pipe 4.

[0087] Specifically, Figures 6 to 8 As shown, an extraction component 5 is used in a combined extraction device for gold-loaded carbon in a carbon slurry process. The extraction component 5 is fixed inside the carbon canister 1, and an impeller 52 rotates relatively inside the carbon canister 1. The driving mechanism 53 is installed at the bottom of the carbon canister 1, which is more convenient for subsequent operation and maintenance of the driving mechanism 53 than installing it at the top of the carbon canister 1, and the driving end thereon is fixedly connected to the impeller 52, and the impeller 52 is connected to the carbon canister 1 in a rotating dynamic seal.

[0088] It should be noted that the present invention is a combined extraction device for gold-loaded carbon in a carbon slurry process. Through the extraction component 5, in the process of extracting gold-loaded carbon from the carbon slurry, the carbon slurry enters the interior of the carbon canister 1 through one of the material pipes 3 attached to the carbon canister 1, and the carbon slurry is filtered through the filter screen 51. After filtering through the filter screen 51, the gold-loaded carbon remains in the interior of the carbon canister 1. The filtered carbon slurry passes through the filter screen 51 and is discharged to the outside of the carbon canister 1 through the discharge pipe 4. After that, the operator can directly obtain the gold-loaded carbon in the carbon canister 1 to extract the gold-loaded carbon.

[0089] As a preferred embodiment, Figure 5 The structure shown is an extraction component 5 for a combined extraction device for gold-carrying carbon in a carbon slurry process, wherein the rectifying member 51-1 is composed of a plurality of plates which are narrow at the bottom and wide at the top, such as Figure 8 The structural state shown is used, on the one hand, to guide the flow of carbon slurry so that the carbon slurry can better act on the filter screen 51 to achieve filtration. On the other hand, the gap between the plates can be determined according to the specific conditions. For example, if the gap is too small, it can effectively prevent large pieces of gold-loaded carbon from directly scouring the filter screen 51, thereby indirectly reducing the probability of damage to the filter screen 51. The plate is fixedly connected to the outer wall of the filter screen 51.

[0090] As described above, in the process of obtaining the gold-loaded carbon in the carbon canister 1, the gold-loaded carbon can be extracted to the outside of the carbon canister 1 by installing a carbon extraction pump 6 inside the carbon canister 1. Figure 6 The structural state shown;

[0091] It is worth mentioning that in the process of extracting the gold-loaded carbon, the driving mechanism 53 drives the impeller 52 to rotate, so as to drive the carbon slurry to accelerate the action on the filter screen 51. After being filtered by the filter screen 51, the gold-loaded carbon is left on the outside of the filter screen 51 and inside the carbon tank 1, and the filtered carbon slurry directly passes through the filter screen 51 and flows out to the outside through the discharge pipe 4 connected to the filter screen 51, and the outside is connected to the discharge pipe 4 to collect the carbon slurry.

[0092] Under the driving action of the driving mechanism 53 on the impeller 52, due to the structure of the impeller 52, the cutting surface is small, and the impeller 52 minimizes the wear of the gold-loaded carbon while ensuring the rapid flow of the carbon slurry during the rotation process. Figure 7 In the structural state shown, the thrust generated by the impeller 52 causes the carbon slurry to move along the axial direction of the filter screen 51 inside the carbon canister 1. Because it is an axial flow type and is used in combination with the truncated cone-shaped filter screen 51, on the one hand, the resistance is small, and on the other hand, because the carbon slurry is inclined to flush the outer wall of the filter screen 51, the wear rate of the gold-loaded carbon is also lower;

[0093] Furthermore, since the filter screen 51 is coaxial with the carbon canister 1, the filter screen 51 can be installed to the maximum extent based on the carbon canister 1. Under the premise of the same carbon slurry flow rate, the extraction efficiency of the gold-loaded carbon can be maximized. Relatively speaking, the overall footprint of the extraction device can be further reduced while ensuring the original extraction efficiency.

[0094] In order to ensure the full extraction of gold-loaded carbon, those skilled in the art can understand that it is appropriate to use a plurality of combined extraction devices in series, that is, the discharge pipe 4 attached to the current extraction device is connected to one of the material pipes 3 of another extraction device cascaded downstream thereof to realize the transfer of carbon slurry. During this period, considering the transfer flow rate of the carbon slurry and the sufficient pressure inside the carbon tank 1, a fluid pump can be optionally installed between the connected material pipe 3 and the discharge pipe 4.

[0095] Furthermore, in this embodiment, taking into account the actual carbon slurry process requirements, such as the carbon slurry process applied to the extraction of a small amount of gold-loaded carbon, in order to further save and ensure the operation and maintenance costs of the combined extraction device, the extraction and pumping of the gold-loaded carbon by the carbon extraction pump 6 can be omitted. Preferably, the discharge pipe 4 for extracting the gold-loaded carbon is opened on the carbon tank 1 at a position adjacent to the impeller 52, such as Fig.23 , 24 In the structural state shown, since the carbon slurry is acted upon by the impeller 52 , after the carbon slurry is effectively filtered through the filter screen 51 , the gold-loaded carbon remaining in the carbon canister 1 can be assisted to be discharged under the action of the impeller 52 . Specific embodiment 2

[0097] Based on the above embodiment 1, in the process of extracting gold-loaded carbon from carbon slurry, considering that the gold-loaded carbon may block the extraction component 5 and thus affect the extraction efficiency of the gold-loaded carbon, this embodiment is proposed:

[0098] Further, such as Fig. 9 , 10 As shown, a combined extraction device for gold-loaded carbon in a carbon slurry process uses a filter screen 51 in an extraction component 5, a grid 511 is fixedly connected to the inside of a carbon canister 1 through a mounting frame 511-1, the grid 511 can be composed of two sections, the upper section is fixed to the carbon canister 1, and the lower section is fixed to the upper section through a connecting rod, and the screen 512 is detachably connected to the grid 511, an inner bucket 513 is movable on the inner side of the grid 511, and the inner bucket 513 is fixedly connected to the driving end of the driving mechanism 53 thereon. It can be understood by those skilled in the art that the driving end of the driving mechanism is such as the rotor of a motor thereon.

[0099] It is worth mentioning that the clearing member 5131 is a scraper or a brush, fixed to the inner bucket 513, and in direct contact with the screen 512. The inner bucket 513 is as follows: Fig.10The frame structure shown can not only provide good support for the screen 512, but also directly clear the blockage on the screen 512 in combination with the clearing piece 5131. Moreover, when the flow rate of the carbon slurry is high or the gold-loaded carbon excessively flushes the screen 512, the inner bucket 513 can support the inside of the screen 512, thereby effectively avoiding excessive deformation of the screen 512 and ensuring the service life of the screen 512.

[0100] In this embodiment, those skilled in the art will appreciate that, in order to ensure the best possible effect of the filter screen 51, the screen 512 is preferably made of a flexible material rather than a hard material such as a steel screen, and the filtering performance of a steel screen is far inferior to that of a screen 512 made of a flexible material such as a polymer, and the pore size is finer and the filtering performance is better. Therefore, when the clearing component 5131 acts on the screen 512, its clearing effect is better, and the inner bucket 513 can support the screen 512. While ensuring a good clearing effect of the screen 512, the use of a flexible screen 512 can maximize the filtering effect of the carbon slurry, and relatively speaking, the filtering and extraction of gold-loaded carbon with the smallest particle size can be achieved.

[0101] Specifically, Figures 11 to 15 As shown, a driving mechanism 53 in an extraction component 5 of a combined extraction device for gold-loaded carbon in a carbon slurry process, an inner gear ring 534 and a gear ring 531 are integrally formed, and the gear ring 531 is fixedly connected to the impeller 52, and the carbon canister 1 is provided with a bottom bin 11 at the installation position of the driving mechanism 53, and a plurality of planetary gears 535 are based on the connecting shaft 535-1 thereon, and are externally connected with a bearing seat 535-2 to rotate relative to the bottom bin 11, and the inner gear ring 534 can rotate relative to the bottom bin 11, and is effectively supported by the bottom bin 11, such as a slide frame that matches the structure of the inner gear ring 534 is provided in the bottom bin 11, and the gear 532 is fixedly connected to the end of the rotor on the motor 533, and the motor 533 is fixedly connected to the carbon canister 1 based on the housing thereon;

[0102] A connecting ring 52 - 1 is provided between the impeller 52 and the inner gear ring 534 , because the connecting ring 52 - 1 penetrates from the inside of the carbon canister 1 to the outside thereof, and the connecting ring 52 - 1 and the carbon canister 1 are connected in a rotating dynamic seal.

[0103] It should be noted that the present invention is a combined extraction device for gold-loaded carbon in a carbon slurry process. Through the provided filter screen 51 and driving mechanism 53, during the extraction of gold-loaded carbon, the carbon slurry flows from the outside of the screen 512 into the inside thereof to achieve effective filtration. During this process, after the motor 533 is started, the gear ring 531 is driven to rotate synchronously through the gear 532. Correspondingly, the impeller 52 is driven to rotate synchronously inside the carbon canister 1 through the inner gear ring 534, thereby accelerating the carbon slurry inside the carbon canister 1 to flow through the screen 512 to achieve filtration.

[0104] Furthermore, while the inner gear ring 534 rotates, the sun gear 536 is driven to rotate synchronously based on the multiple planetary gears 535, and the rotation of the sun gear 536 drives the inner bucket 513 connected thereto to rotate synchronously. Therefore, since the screen 512 is fixed to the inside of the charcoal canister 1, during the rotation of the inner bucket 513, the inner bucket 513 rotates relative to the screen 512, and the inner bucket 513 directly acts on the inner wall of the screen 512 through the clearing piece 5131 attached thereto, thereby achieving silt removal of the screen 512.

[0105] During this period, because the grid frame 511 is connected and communicated with the discharge pipe 4 by a rotary dynamic seal through the sun gear 536, the filtered carbon slurry flows out through the discharge pipe 4 via the sun gear 536;

[0106] Further, such as Fig.16 As shown, a sun gear 536 used in a driving mechanism 53 of an extraction component 5 of a combined extraction device for gold-loaded carbon in a carbon slurry process, a main gear 5361 meshing with a plurality of planetary gears 535, and the main gear 5361 is fixedly connected to two sealing chambers 5362, the two sealing chambers 5362 are respectively connected to the opposite ends of the discharge pipe 4 and the filter screen 51 in a rotating dynamic seal, and the main gear 5361 is a hollow structure based on a plurality of material holes 5361-1 opened thereon.

[0107] It should be noted that the filtered carbon slurry flows from the grid 511 to the sealed chamber 5362, and then flows from the sealed chamber 5362 to the discharge pipe 4, passing through the main gear 5361. As a preferred embodiment, the main gear 5361 is provided with a plurality of material holes 5361-1 based on its axial direction.

[0108] It is worth mentioning that the structural setting of the driving mechanism 53 allows the discharge pipe 4 and the driving mechanism 53 to be located at the same end or the same side, which makes it more convenient for the operator to subsequently operate and maintain the extraction device. In addition, based on the characteristics of the attached planetary gears, the driving mechanism 53 can be used as a reducer, thereby eliminating the cost of installing additional speed change equipment. Specific embodiment three

[0110] Based on the above-mentioned embodiment 2, in order to further improve the extraction efficiency of gold-loaded carbon and further ensure a good filtering effect on carbon slurry, this embodiment is proposed:

[0111] Specifically, Fig.17 As shown, an extraction component 5 used in a combined extraction device for gold-loaded carbon in a carbon slurry process, an inner plate 55 is provided on the inner side of a filter screen 51, and the inner plate 55 is spiral in shape as a whole, and the inner plate 55 is also fixed to the output end of a driving mechanism 53 thereon, and the driving mechanism 53 drives the inner plate 55 to rotate relative to the axial direction of the filter screen 51.

[0112] Further, such as Fig.18 As shown, an inner plate 55 in an extraction component 5 used in a combined extraction device for gold-loaded carbon in a carbon slurry process, the inner plate 55 includes a substrate 551, and the substrate 551 is a hollow structure and is externally connected to a gas supply source, and a plurality of air holes 5511 are provided on one side of the substrate 551 relative to the inner side of the filter screen 51; the gas supply source is preferably an air pump, because the inner plate 55 supplies air from top to bottom, thereby effectively preventing the carbon slurry in the carbon tank 1 from flowing back, without the need to set up an anti-backflow component inside the substrate 551.

[0113] It should be noted that the present invention is a combined extraction device for gold-loaded carbon in a carbon slurry process. Through the extraction component 5, during the process of extracting the gold-loaded carbon, the driving mechanism 53 drives the inner bucket 513 to rotate relative to the grid frame 511, and the inner plate 55 attached to the inner bucket 513 rotates synchronously with it. Due to the structure of the inner plate 55, during the rotation of the inner plate 55, a downward thrust can be formed on the carbon slurry located on the inner side of the screen 512, thereby accelerating the discharge of the filtered carbon slurry;

[0114] In addition, because the inner plate 55 can form a downward thrust, and combined with the overall structural state of the filter screen 51, it can play a role in flushing the filter screen 51 from the inside to the outside, thereby ensuring the good permeability of the filter screen 51 to the greatest extent;

[0115] Among them, those skilled in the art can understand that the base plate 551 can be equipped with bristles or a scraper at the contact portion with the inner bucket 513 , which has the same effect as the clearing member 5131 .

[0116] It is worth mentioning that, since the substrate 551 is connected to an external gas supply source based on the substrate tube 553, during the extraction of the gold-loaded carbon, by starting the gas supply source, the base tube 553 pumps the gas pressure source to the substrate 551, and the gas is discharged from the multiple air holes 5511 opened on the substrate 551, so that the gas pressure directly acts on the screen 512, thereby achieving effective blowing of the screen 512, and further ensuring the anti-clogging effect of the screen 512;

[0117] Moreover, when the gas is ejected from the multiple air holes 5511 opened on the substrate 551, the substrate 551 rotates synchronously with the inner bucket 513, thereby realizing all-round blowing on the screen 512. While ensuring the good permeability of the screen 512, it can directly avoid blowing on a single part of the screen 512, and indirectly extend the service life of the screen 512. Specific embodiment 4

[0119] Based on the above-mentioned third embodiment, in the process of extracting gold-loaded carbon, considering that the carbon slurry is adhered to the inside of the inner bucket 513 by scale, or in order to facilitate the cleaning of the filter screen 51, this embodiment is proposed:

[0120] Furthermore, if Fig.16 As shown, a driving mechanism 53 of an extraction component 5 is used in a combined extraction device for gold-loaded carbon in a carbon slurry process, and the telescopic member 537 is any one of a cylinder or a hydraulic cylinder, and the end of the telescopic section thereof is rotatably connected to a spline shaft 56.

[0121] Furthermore, Fig.18 As shown, a combined extraction device for gold-loaded carbon in a carbon slurry process uses an inner plate 55 in an extraction component 5, a base plate 551 is fixedly connected to one end of a spline shaft 56, and an end of the base plate 551 away from the spline shaft 56 is fixedly connected to and communicated with a movable tube 552.

[0122] Furthermore, Fig. 20 As shown, a combined extraction device for gold-loaded carbon in a carbon slurry process uses an inner bucket 513 for a filter screen 51 in an extraction component 5, a connecting frame 5133 is provided at the junction of the inner bucket 513 and a driving mechanism 53, and a spline groove 5134 is provided on the connecting frame 5133 at the axial direction of the inner bucket 513.

[0123] It should be noted that, in the process of extracting the gold-loaded carbon or in the process of cleaning the filter screen 51, it is necessary to change the motion state of the inner plate 55 and the inner bucket 513 so that the inner plate 55 can achieve the cleaning effect on the inner wall of the inner bucket 513:

[0124] In the process of changing the motion state of the inner bucket 513 and the inner plate 55, the telescopic member 537 is started, and the telescopic section of the telescopic member 537 drives the spline shaft 56 to move based on the axial direction of the filter screen 51. After the upper spline of the spline shaft 56 is separated from the spline groove 5134, at the same time, the spline shaft 56 drives the limit member 554 to move based on the base plate 551 and the movable tube 552, and the limit member 554 is used to limit the rotation of the inner bucket 513, so that the inner bucket 513 is fixed to the grid frame 511. Fig. 22 The structural state shown;

[0125] After the upper spline of the spline shaft 56 is disengaged from the meshing with the connecting frame 5133 based on the spline groove 5134, and the grid frame 511 and the inner bucket 513 are fixed by the stopper 554, in this state, the base plate 551 is just in contact with the inner wall of the inner bucket 513, and the motor 533 is started to drive the gear 532 to rotate, and indirectly, the sun gear 536 also rotates synchronously during the rotation of the gear 532;

[0126] Since the sun gear 536 as a whole is based on the meshing of the shaft sleeve 5363 and the spline shaft 56, during the rotation of the sun gear 536, the sun gear 536 drives the inner plate 55 to rotate based on the spline shaft 56. Therefore, the base plate 551 directly acts on the inner wall of the inner bucket 513, thereby achieving the scraping of scale on the inner wall of the inner bucket 513.

[0127] As a preferred embodiment, Fig.19 As shown, a limiting piece 554 is used for the inner plate 55 of the extraction component 5 of the combined extraction device for gold-loaded carbon in a carbon slurry process. The connection between the connecting plate 5541 and the movable tube 552 is relatively rotated through the bearing 5541-1, and cannot be axially moved. The first latch 5542 and the second latch 5543 are fixedly connected to the connecting plate 5541. It can be understood by those skilled in the art that the density of the limiting grooves 5111 depends on the actual usage. The number of limiting grooves 5111 corresponds to the pluggable rotation angle of the second latch 5543 based on the connecting plate 5541. In order to ensure the good docking of the second latch 5543 and the limiting groove 5111 in the future, it is necessary to select a servo motor as the motor 533. By utilizing the programmability of the servo motor, after the substrate 551 rotates a full circle, the second latch 5543 can be directly opposite to the limiting groove 5111.

[0128] It should be noted that the present invention is a combined extraction device for gold-loaded carbon in a carbon slurry process. By setting a limiter 554, under normal conditions, that is, the movement state of the inner plate 55 and the inner bucket 513 is relatively static, and the inner plate 55 moves synchronously with the inner bucket 513. Fig.21 In the structural state shown, the upper spline of the spline shaft 56 is meshed with the connecting frame 5133 based on the spline groove 5134, and the second latch 5543 is disengaged from the limit groove 5111. In this state, the relative rotation between the inner bucket 513 and the grid frame 511 is not affected;

[0129] In addition, when the inner bucket 513 and the inner plate 55 are in relative motion, Fig. 22 In the structure shown, the upper spline of the spline shaft 56 is disengaged from the connecting frame 5133 based on the spline groove 5134, and the second latch 5543 is engaged with the limit groove 5111 at this time, so that the first latch 5542 and the second latch 5543 restrict the relative rotation of the frame 511 and the inner bucket 513 based on the connecting plate 5541, thereby realizing the relative state of the spline shaft 56 driving the inner plate 55 based on the inner bucket 513.

[0130] It can be understood by those skilled in the art that, as an ideal operating principle, after the telescopic member 537 drives the spline shaft 56 to telescopically move based on its axial direction, when the second latch 5543 is engaged with the limiting groove 5111, the base plate 551 is in contact with the inner wall of the inner bucket 513, and Fig.21 In the structural state shown, since the substrate 551 is not attached to the inner wall of the inner bucket 513, in this state, the normal outflow of gas from the air hole 5511 is not affected, so as to ensure the normal operation of the substrate 551;

[0131] Furthermore, in the actual implementation process, those skilled in the art will appreciate that sealing measures, such as a sealing gasket, may be installed at the joint between the spline shaft 56 and the sleeve 5363 to ensure the normal function of the extraction component 5.

[0132] It is worth mentioning that in this embodiment, the inner wall of the inner bucket 513 can be cleaned during the extraction of gold-loaded charcoal without the need for excessive cumbersome operations of dismantling the device. In addition, in order to further reduce the overall footprint of the device, the spline shaft 56 and the telescopic member 537 are installed based on the axial direction of the filter screen 51, and the telescopic section of the telescopic member 537 is based on the through groove 4-1 and is dynamically sealed with the discharge pipe 4, such as Fig.14 , 15 The structural status shown.

[0133] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for illustrating the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed for protection.
