Description

Technical Field

[0001] The invention belongs to the technical field of cyanidation reaction, in particular to a continuous cyanidation reaction device. Background Art

[0002] Cyanidation reaction is an important step in organic synthesis and is widely used in the synthesis of chemicals such as drugs, pesticides, dyes, and fragrances.

[0003] In the process of extracting gold from gold ore, the ore is first crushed and ground into powder, the powder is mixed with water to form gold slurry, and then the gold slurry and cyanide solution are poured into a continuous cyanide reaction device, stirred by a scraper and added with oxygen to cause cyanide reaction, the gold in the gold slurry is dissolved into the solution, and the deposited ore particles are discharged by a scraper and a water pump. After solid-liquid separation, zinc powder is added to the liquid containing gold ions to form debris containing zinc and gold, a solvent is added to the debris and high-temperature calcination is performed to make impurities float on the gold solution, and after the impurity solution on the surface is poured out, the gold solution is poured into a mold and cooled to form gold bricks.

In the process of mixing gold ore slurry and cyanide solution, the gold in the ore powder will dissolve into the solution through the cyanidation reaction, and the ore particles will settle to the bottom of the device under the action of gravity. When the scraper scrapes the ore particles settled at the bottom of the device, because the scraper is comb-shaped and there is a gap between two sets of adjacent scrapers, some areas cannot be scraped during the scraping of the ore particles at the bottom of the device, and the unscraped ore particles will accumulate inside the device, eventually causing equipment blockage or wear, which will not only affect the normal operation of the equipment, but also increase the cost of maintenance and replacement of equipment.

[0046] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0047] Embodiment 1

[0048] like Figures 1 to 15 As shown, a continuous cyanidation reaction device according to an embodiment of the present invention comprises a reaction box 1, wherein a liquid injection port 11 is symmetrically fixedly connected to the top of the reaction box 1, and an air hole 12 is fixedly connected to the top of the reaction box 1, wherein the liquid injection port 11 and the air hole 12 are both connected to the reaction box 1, and a collecting slot 13 is provided in the middle of the bottom of the reaction box 1, and a water pump is provided at the bottom of the reaction box 1, and a water suction port of the water pump is connected to the collecting slot 13, and the ore particles in the collecting slot 13 are discharged through the water pump, so that the discharged ore particles and the mixed liquid enter the next process, and an agitator 2 is rotatably connected between the bottom of the collecting slot 13 and the top of the reaction box 1, and the agitator 2 is composed of two vertical rotating shafts and a rotating block, and two contraction grooves are symmetrically provided inside the rotating block, and the rotating block is located between the two vertical rotating shafts, and one end of the two vertical rotating shafts close to the rotating block is fixed to the rotating block, and a one-way motor 21 is fixedly connected to the top of the reaction box 1, and the output end of the one-way motor 21 is fixed to one end of the vertical rotating shaft located above the rotating block, and five scrapers 44 are provided at the bottom of the rotating block;

[0049] A telescopic assembly 3 is arranged in the contraction groove, and the telescopic assembly 3 includes a telescopic box 31. The telescopic box 31 is located at one end of the contraction groove close to the vertical shaft. A displacement block 35 is slidably arranged in the contraction groove. A reciprocating screw rod 38 is rotatably arranged in the telescopic box 31. The reciprocating screw rod 38 is rotated to control the contraction and extension of the displacement block 35, so that the scraper 44 can clean the ore particles in the adjacent areas.

[0050] A flip assembly 4 is provided on the telescopic assembly 3, and the flip assembly 4 includes a fixedly arranged resistance rod 412. A connecting block 41 is provided on each scraper 44. The scraper 44 is rotated by the resistance rod 412, so that the scraper 44 is perpendicular to the connecting block 41, so that the scraper 44 can clean the granular ore particles more efficiently.

[0051] Specifically, the existing continuous cyanidation reaction device still has some problems in actual use. In the process of mixing the gold ore slurry and the cyanide solution, the gold in the ore powder will dissolve into the solution through the cyanidation reaction, and the ore particles will settle to the bottom of the reaction box 1 under the action of gravity. When the scraper 44 scrapes the ore particles settled at the bottom of the reaction box 1, since the scraper 44 is comb-shaped and there is a gap between two groups of adjacent scrapers 44, there will be some areas that cannot be scraped during the scraper 44 scraping the ore particles at the bottom of the reaction box 1, and the unscraped ore particles will accumulate inside the reaction box 1, eventually causing the entire device to be blocked or worn, which will not only affect the normal operation of the equipment, but also increase the cost of maintenance and replacement of the equipment.

[0052] Therefore, the present invention solves this problem by setting a corresponding structure. The gold ore pulp and the cyanide solution enter the reaction box 1 through two injection ports 11 respectively, and oxygen is input into the reaction box 1 through an air hole 12, so that the mixed liquid undergoes cyanidation reaction under the stirring action of the scraper 44 on the stirrer 2, so that the gold is dissolved in the mixed liquid, and the ore particles are precipitated to the bottom of the reaction box 1 under the action of gravity. The bottom of the reaction box 1 is arc-shaped, and the bottom end is connected to the collecting slot 13, so that part of the ore particles roll into the collecting slot 13, and the ore particles in the collecting slot 13 are discharged by a water pump, so that the discharged ore particles and the mixed liquid enter the next process, and the harmful gas generated by the reaction is discharged through another air hole 12, and is subsequently treated;

[0053] During the continuous cyanidation reaction, the telescopic assembly 3 is extended and retracted by rotating the reciprocating screw 38 , and the scraper 44 is turned over during the movement, so that the scraper 44 can efficiently clean the granular ore particles at the bottom of the reaction box 1 .

[0054] Embodiment 2

[0055] like Figures 2 to 15 As shown, compared with Example 1, another implementation of the present invention is:

[0056] like Figures 2 to 4 As shown, the telescopic component 3 of this embodiment also includes an inner cavity groove 36, which is opened in the middle of the rotating block. A bidirectional anti-corrosion motor 37 is fixedly connected to the inner cavity groove 36, and the telescopic component 3 is telescoped by rotating the output end of the bidirectional anti-corrosion motor 37.

[0057] Specifically, the bidirectional anti-corrosion motor 37 is started at a fixed time, and the rotation of the output shaft of the bidirectional anti-corrosion motor 37 drives the components fixed thereto to rotate.

[0058] like Figures 2 to 10As shown, the telescopic assembly 3 of this embodiment is composed of a telescopic component and a transmission component. The telescopic component includes a telescopic box 2 32, and the telescopic box 2 32 slides inside the telescopic box 1 31. The end of the telescopic box 2 32 away from the telescopic box 1 31 is slidably connected to the telescopic box 3 33, and the end of the telescopic box 3 33 away from the telescopic box 2 32 is slidably connected to the telescopic box 4 34, and the end of the telescopic box 4 34 away from the telescopic box 3 33 is slidably connected to the displacement block 35. When the contraction component slides toward the direction close to the telescopic box 1 31, it is contracted, and when it slides toward the direction away from the telescopic box 1 31, it is extended;

[0059] The transmission component includes a sliding column 39, one end of which is fixed inside the end of the telescopic box 2 32 close to the telescopic box 1 31, the reciprocating screw 38 penetrates the telescopic box 1 31 and rotates inside the telescopic box 1 31, the reciprocating screw 38 is threadedly connected to the sliding column 39, the end of the sliding column 39 away from the reciprocating screw 38 is fixedly connected to the hollow block 310, the end of the hollow block 310 away from the sliding column 39 is fixedly connected to the fixed rod 311, and the end of the fixed rod 311 close to the displacement block 35 is fixedly connected to the displacement block 35, the sliding column 39 is extended and contracted by the rotation of the reciprocating screw 38, and then the displacement block 35 is driven to extend and contract;

[0060] The transmission component also includes a guide pulley 312, which is rotatably arranged on a side of the telescopic box 2 32 close to the telescopic box 1 31, and a sliding rope 313 is fixedly connected between the inner wall of the end of the telescopic box 2 32 away from the telescopic box 1 31 and the inner wall of the end of the telescopic box 1 31 close to the telescopic box 2 32, and the sliding rope 313 slides on the guide pulley 312;

[0061] The inner wall of one end of the telescopic box 3 33 away from the telescopic box 2 32 is rotatably connected to the guide pulley 2 314, and the inner wall of the telescopic box 4 34 close to the telescopic box 3 33 and the inner wall of the telescopic box 2 32 close to the telescopic box 1 31 are fixedly connected with the slide rope 2 315, and the slide rope 2 315 slides on the guide pulley 2 314;

[0062] The inner wall of the telescopic box three 33 near the end of the telescopic box two 32 is rotatably connected with a guide pulley three 316, the end of the telescopic box four 34 near the telescopic box three 33 and the end of the hollow block 310 near the sliding column 39 are fixedly connected with a sliding rope three 317, the interior of the hollow block 310 is rotatably connected with a guide pulley four 318, and the inner wall of the telescopic box three 33 near the end of the telescopic box two 32 and the inner wall of the telescopic box one 31 away from the telescopic box two 32 are fixedly connected with a sliding rope four 319.

[0063] Specifically, initially, the telescopic assembly 3 is extended to the farthest distance, and the output end of the bidirectional anti-corrosion motor 37 is fixed to the reciprocating screw rod 38;

[0064] When the reciprocating screw rod 38 rotates, the telescopic box 2 32 is driven to contract through the sliding column 39. The contraction of the sliding column 39 drives the hollow block 310, the fixed rod 311 and the second sliding rope 315 to contract synchronously. When the telescopic box 2 32 contracts, the distance between the two straight lines formed by the sliding rope 1 313 changes under the guidance of the guide pulley 1 312, so that the sliding rope 1 313 also pulls the telescopic box 2 32 to contract, further ensuring the contraction of the telescopic box 2 32. The same applies to the other transmission components, thereby ensuring the stability of the telescopic components.

[0065] When the slide column 39 contracts to the top of the reciprocating screw rod 38, the reciprocating screw rod 38 continues to rotate, causing the slide column 39 to begin to extend. Through the above operation, the telescopic component begins to extend.

[0066] The present invention enables the ore particles that cannot be scraped off in some areas to be cleaned by extending and retracting the telescopic component, thereby increasing the scope of cleaning the ore particles. At the same time, the telescopic component drives the scraper 44 to extend and retract synchronously, and can also adjust the stirring area, thereby improving the stirring effect.

[0067] like Figure 8 As shown, in this embodiment, a guide block is provided inside the slide post 39 , and the slide post 39 is reciprocated by the guide block along with the rotation of the reciprocating screw rod 38 .

[0068] Specifically, through the guide block in the slide column 39, the guide block moves along the direction of the reciprocating thread groove of the reciprocating screw rod 38 when the reciprocating screw rod 38 rotates, thereby driving the slide column 39 to reciprocate.

[0069] like Figures 2 to 6 As shown, in this embodiment, the bottom of the telescopic component corresponds to the five scrapers 44 one by one, and the scrapers 44 are driven to telescope synchronously when the contraction component moves.

[0070] Specifically, a scraper 44 is disposed at the bottom of each telescopic component, so that the area between adjacent scrapers 44 can be cleaned when the telescopic component is retracted.

[0071] like Figures 2 to 6 and Figures 11 to 15 As shown, the flip assembly 4 of this embodiment is composed of a fixed component and a displacement component. The fixed component includes a rotation groove 42, which is opened at the bottom of the connecting block 41. The rotation groove 42 is rotatably connected to a shaft 43. The scraper 44 is fixed to the surface of the shaft 43. The bottom of the telescopic box 32 is provided with a displacement component, and the bottoms of the other telescopic components are provided with fixed components.

[0072] The displacement component includes a component of a fixed component, a resistance groove 45 is provided in the connecting block 41, a movement groove 46 is provided in the connecting block 41, the movement groove 46 is L-shaped, and is composed of a horizontal straight groove and a vertical straight groove, one end of the horizontal straight groove is connected to the top of the vertical straight groove, the resistance groove 45 is connected to the movement groove 46, a rotating gear rod 47 is rotatably connected in the resistance groove 45, a resistance block 48 is fixedly provided on the surface of the rotating gear rod 47, a spring 414 is fixedly connected between one side of the resistance block 48 and the bottom of the resistance groove 45, a transmission bevel gear rod 1 49 is rotatably connected in the horizontal straight groove, a transmission bevel gear rod 2 410 is rotatably connected in the vertical straight groove, and a guide bevel gear 411 is fixedly connected to one end of the shaft rod 43;

[0073] One side of the telescopic box 31 on the fixed component is fixedly connected with a resistance rod 412, and the resistance rod 412 slides in the resistance groove 45 of the adjacent displacement component. One side of the scraper 44 on the telescopic box 31 is fixedly connected with a limiting rod 413, and the limiting rod 413 passes through the scrapers 44 on the other telescopic components.

[0074] Specifically, initially, the spring 414 remains stationary, the abutment block 48 remains vertical, one end of the abutment rod 412 abuts against a abutment block 48 close to the abutment rod 412, and the scraper 44 and the connection block 41 are in the same vertical plane;

[0075] When the telescopic component begins to shrink, the scraper 44 thereon shrinks synchronously, so that the abutment block 48 abuts against the abutment rod 412, and the abutment rod 412 pushes the abutment block 48 to flip, and drives the rotating gear rod 47 to rotate 90 degrees, so that the abutment block 48 elastically compresses the spring 414 and is not enough to stop the spring 414. At this time, the spring 414 passes through the abutment groove 45. At this time, except for the scraper 44 on the telescopic box 1 31, the other scrapers 44 slide on the limit rod 413;

[0076] Both ends of the transmission bevel gear rod 1 49 and the transmission bevel gear rod 2 410 are provided with bevel gears, and the bevel gears at the adjacent ends thereof are meshed with each other, the other bevel gear on the transmission bevel gear rod 1 49 is meshed with the rotating bevel gear on the rotating gear rod 47, and the bevel gear at the bottom end of the transmission bevel gear rod 2 410 is meshed with the guide bevel gear 411;

[0077] By rotating the gear rod 47, under the transmission effect of the transmission bevel gear rod 1 49 and the transmission bevel gear rod 2 410, the guide bevel gear 411 is driven to rotate clockwise, thereby driving the scraper 44 to flip 90 degrees, so that the scraper 44 on the telescopic box 2 32 is perpendicular to the connecting block 41, and the remaining scrapers 44 are driven to flip synchronously through the limit rod 413, so that the scraper 44 can clean the ore particles more efficiently;

[0078] During the extension of the telescopic component, when the resistance rod 412 no longer squeezes the resistance block 48, the resistance block 48 is reset through the elastic reset of the spring 414. At the same time, under the action of the gravity of the scraper 44 itself, the scraper 44 flips downward. Through the reset of the resistance block 48 and the solid action of the gravity of the scraper 44 itself, the scraper 44 is reset through the above operations.

[0079] The present invention squeezes the resistance block 48 by the resistance rod 412 to rotate the resistance block 48, thereby driving the scraper 44 under the telescopic box 2 32 to rotate, and drives the remaining scrapers 44 to turn over synchronously by the limit rod 413, so that the scraper 44 can more efficiently clean the ore particles deposited at the bottom of the reaction box 1, thereby improving the cleaning effect of the scraper 44.

[0080] The present invention improves the efficiency of the scraper 44 in cleaning the entire bottom of the reaction box 1 and strengthens the cleaning effect on the ore particles by turning over the scraper 44 when the telescopic part contracts.

[0081] Working principle:

[0082] During the continuous cyanidation reaction, the stirrer 2 is driven to rotate by the unidirectional motor 21, so that the scraper 44 rotates synchronously with the stirrer 2 and cleans the ore particles at the bottom of the reaction box 1;

[0083] When the stirrer 2 rotates, the reciprocating screw rod 38 is driven to rotate, so that the slide column 39 drives the telescopic box 2 32 to contract. The contraction of the slide column 39 drives the hollow block 310, the fixed rod 311 and the second slide rope 315 to contract synchronously. When the telescopic box 2 32 contracts, the distance between the two straight lines formed by the slide rope 1 313 changes under the guidance of the guide pulley 1 312, so that the slide rope 1 313 also pulls the telescopic box 2 32 to contract, further ensuring the contraction of the telescopic box 2 32. The same applies to the other transmission components.

[0084] When the telescopic component begins to shrink, the scraper 44 thereon shrinks synchronously, so that the abutment block 48 abuts against the abutment rod 412, and the abutment rod 412 pushes the abutment block 48 to flip, and drives the rotating gear rod 47 to rotate 90 degrees, so that the abutment block 48 elastically compresses the spring 414 and is not enough to stop the spring 414. At this time, the spring 414 passes through the abutment groove 45. At this time, except for the scraper 44 on the telescopic box 1 31, the other scrapers 44 slide on the limit rod 413;

[0085] By rotating the gear rod 47, under the transmission effect of the transmission bevel gear rod 1 49 and the transmission bevel gear rod 2 410, the guide bevel gear 411 is driven to rotate clockwise, thereby driving the scraper 44 to flip 90 degrees, so that the scraper 44 on the telescopic box 2 32 is perpendicular to the connecting block 41, and the remaining scrapers 44 are driven to flip synchronously through the limit rod 413, so that the scraper 44 can clean the ore particles more efficiently;

[0086] When the slide column 39 contracts to the top of the reciprocating screw rod 38, the reciprocating screw rod 38 continues to rotate, so that the slide column 39 begins to extend. Through the above operation, the telescopic component begins to extend.

[0087] During the extension of the telescopic component, when the resistance rod 412 no longer squeezes the resistance block 48, the resistance block 48 is reset through the elastic reset of the spring 414. At the same time, under the action of the gravity of the scraper 44 itself, the scraper 44 flips downward. Through the reset of the resistance block 48 and the solid action of the gravity of the scraper 44 itself, the scraper 44 is reset through the above operations.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
