Description

TECHNICAL FIELD

[0001] The application relates to a reaction kettle, in particular to a reaction kettle for processing arsenic filter cake. BACKGROUND

[0002] After being collected and processed, the flue gas generated in the copper smelting process can produce sulfuric acid products every year, but at the same time, thousands of tons of copper arsenic filter cake which is difficult to handle will be left, the filter cake contains various heavy metals, and if it is randomly discharged, not only the resources will be lost, but also environmental pollution will be caused, in order to extract the metal substances in the filter cake, the methods for extracting the metal mainly include a precipitation-oxidation calcination method, a neutralization precipitation-ion exchange method, a solvent extraction method and an oxygen pressure leaching method.

[0003] The traditional oxygen pressure leaching method is to input oxygen from the bottom of the reaction kettle, and then input the slurried filter cake from the top of the reaction kettle, so that the slurried filter cake is oxidized into a dissoluble substance under the action of oxygen under the condition of high-pressure oxygen, so as to realize the extraction of the metal, but the leaching effect is poor by using the static leaching method, therefore, the prior art adopts the method of arranging a plurality of stirring structures on the top of the reaction kettle to overturn the slurry at the bottom and improve the leaching effect, although the stirring structures have a part of the effect of promoting the reaction, but due to the fact that the length of the whole reaction kettle is very long, if the stirring structures are arranged at a short distance and at a high frequency, although the effect of overturning the slurry uniformly can be achieved, not only the overall cost is increased, but also the stirring forces of the stirring structures are easy to cancel out each other, and if the stirring structures are arranged at a long distance, the slurry in a large blank area is easy to be always in a static state, so that the slurry in the position is not fully leached, and the overall utilization effect of the slurry is limited.

[0004] Therefore, the application aims to provide a reaction kettle for processing arsenic filter cake, which can uniformly stir the slurry settled at the bottom, and the slurry at the bottom can uniformly contact with oxygen under the high-pressure environment, so as to improve the leaching effect of the metal substances in the slurry, and the metal substances can be more completely leached during the recovery, and the recovery rate is higher. SUMMARY

[0005] The application provides a reaction kettle for processing arsenic filter cake, which can effectively solve the above problems.

[0006] The application is implemented as follows:

[0007] The application provides a reaction kettle for processing arsenic filter cake, which can effectively solve the above problems.

[0008] The lower extension structure includes a long through pipe disposed in the lower half of the interior of the autoclave. The long through pipe has a lower connecting member inside. The lower connecting member rotates under the action of oxygen output from the oxygen feed pipe. The lower connecting member is connected to a conversion member. The top of the conversion member is provided with a bottom swing member. When the lower connecting member rotates, it drives the conversion member to rotate, which in turn causes the conversion member to drive the bottom swing member to swing. The top of the bottom swing member is sleeved on the bottom of the stirring rod.

[0009] The linkage stirring structure includes a transverse rotating shaft disposed at both ends of the conversion component and located inside the long tube. A stirring component is fixedly connected to the transverse rotating shaft. The stirring component is disposed in the middle of the projection positions of the two stirring structures and extends to the outside of the long tube.

[0010] The multi-stage mixing structure has a hollow stirring section of the stirring rod, with several first mixing ports at the lower end of the stirring section, several second mixing ports on the outer side of the bottom swing member, and several third mixing ports on the outer side of the tumbling member. High-pressure oxygen input from the oxygen feed pipe is driven to rotate the connecting member and then fed into the interior of the high-pressure vessel through the first, second, and third mixing ports respectively. A waste gas conduction valve is provided at the top of the high-pressure vessel.

[0011] As a further improvement, the long tube includes an elongated tube with several flat surfaces at its upper end and several mounting grooves for mounting the stirring components spaced apart on the elongated tube.

[0012] As a further improvement, the lower end of the long tube is connected to several lower extension tubes. The lower connecting member includes a positioning ring groove connected inside the lower extension tube. A rotating ring is movably arranged inside the positioning ring groove. An air ring is arranged inside the rotating ring. When high-pressure oxygen rushes into the air ring, the air ring rotates. An active wheel frame is connected to the top of the air ring. The active wheel frame is connected to the conversion member.

[0013] As a further improvement, the drive wheel frame includes a hollow tube connected to the outer edge of the rotating ring, the top of the hollow tube extending into the long tube, and a conical tooth surface connected to the top of the hollow tube, the conical tooth surface engaging with the conversion element.

[0014] As a further improvement, the conversion component includes two side bevel gears connected to the inclined surface of the bevel gear, and an upper conical wheel is provided at intervals on the inclined surface at the upper end of the side bevel gear. The upper conical wheel is connected to the hollow tube through a through pipe, and the upper conical wheel is connected to the lower end of the bottom swing component.

[0015] As a further improvement, the bottom swing member includes a lower moving plate embedded in a flat surface, the bottom surface of the lower moving plate is in contact with the top surface of the upper conical wheel, a stirring plate is provided at the upper end of the lower moving plate, and a plurality of stirring rods are provided on the outer side of the stirring plate.

[0016] As a further improvement, a receiving sleeve is provided at the top of the stirring plate, and the receiving sleeve is located at the lower end of the stirring rod.

[0017] As a further improvement, the stirring component includes an inner connecting ring sleeved on a transverse rotating shaft, an outer connecting ring provided on the outer side of the inner connecting ring, the inner connecting ring enclosing the mounting groove, and a plurality of stirring handles provided on the outer side of the outer connecting ring.

[0018] The beneficial effects of this invention are:

[0019] Existing reactors are generally quite long. If the stirring structures are installed over a long distance, large blank areas of slurry may remain inactive, resulting in insufficient leaching and limited overall utilization of the slurry. Conversely, if the stirring structures are installed too close together, they become too dense. Therefore, this invention first uses a downward extension structure. A long pipe, roughly the same length as the reactor body, is installed at the lower end of the reactor. A lower connecting member is installed within this pipe. Oxygen drives the lower connecting member to rotate, which in turn rotates the bottom oscillating component. This significantly extends the stroke of the stirring structure, avoiding instability caused by long-distance control. The pumping force from the high-pressure oxygen input provides the lower-end force, eliminating the need for additional power structures within the high-pressure reactor, which already contains harmful substances, thus ensuring the purity of the reactants during the reaction process.

[0020] The upper end of the long tube actually needs to have space for the bottom swinging component, so a conventional long tube cannot be used. Therefore, the top surface of the long tube in this invention is a flat surface and is set in sections, so that it can be used to install the bottom swinging component and the tumbling component.

[0021] Since there are multiple sets of high-pressure oxygen inlets, multiple sets of structures connecting to the high-pressure oxygen inlets also need to be set in the long pipe. Therefore, the long pipe of the present invention is provided with several lower extension pipes. The air ring in the lower extension pipe can rotate when high-pressure oxygen is introduced, and the rotation drives the rotating ring, thereby serving as the power source for the bottom swinging member and the tumbling member.

[0022] The wind ring cannot be used directly as a power source. It needs other transfer structures when it is transmitted to other components. Therefore, the bottom surface of the active wheel frame of the present invention is connected to the rotating ring. When the rotating ring rotates, it can drive the active wheel frame to rotate, thereby changing the direction of the entire rotational power transmission. Furthermore, by means of the bevel tooth surface, it can be set as a connecting force on the inclined surface, so that it can cooperate with the conversion component.

[0023] However, the conversion component in this invention is not simply a one-sided conversion, but rather a multi-directional conversion method. Specifically, the conversion component of this invention first needs to transmit the rotational force to the axial position of the long tube through two side bevel gears, so as to drive the tumbling component to rotate. Secondly, it also needs to transmit the rotational force to the position of the upper conical wheel through the through pipe, so that the upper conical wheel can drive the bottom swing component to rotate. Therefore, the conversion component of this invention can convert the force into at least three directions. The distributed rotation method can save more on the design of more structures. The simplified structure setting can effectively reduce costs and avoid more failures.

[0024] Because the autoclave is quite deep, the stirring structure cannot extend too far. Therefore, this invention uses a bottom oscillating component to compensate for this limitation. The bottom oscillating component is connected to the upper conical wheel via a lower moving plate, and thus drives the lower moving plate to rotate when the upper conical wheel is driven. However, this does not interfere with the stirring structure. Furthermore, to better regulate the rotation of the stirring structure, a receiving sleeve is provided at the top of the stirring plate to support the stirring rod, thereby ensuring that the end of the stirring rod is subject to certain limits and thus regulates its rotation.

[0025] Furthermore, based on the lower extension structure, the present invention also drives the entire linkage stirring structure through the lower connecting member and the conversion member, thereby allowing individual stirring members to be set between two adjacent stirring structures, thus ensuring that the stirring areas are reasonably spaced inside the high-pressure reactor, and that leaching can be fully carried out in a high-pressure oxygen environment.

[0026] When the agitator rotates, it needs to ensure the sealing of the inside of the long pipe while also having a certain agitation effect. Therefore, the agitator of the present invention is provided with an inner connecting ring for sealing the mounting groove of the long pipe. The inner connecting ring is then connected to an outer connecting ring. The agitator handle is set through the outer connecting ring so that the agitator handle can agitate the water, thereby ensuring the sealing of the inside of the long pipe during the entire high-pressure oxygen intake process, preventing the solution from intervening and affecting the driving effect of oxygen on the air ring, while also allowing the agitator to have an agitation effect.

[0027] After using high-pressure oxygen as a power source, how to mix it evenly and quickly with the solution inside the autoclave is also a crucial point to consider under oxygen pressure leaching conditions. Therefore, this design incorporates multiple mixing structures on top of the extended lower structure and the linked stirring structure, thereby ensuring that oxygen can be output from different points, thus guaranteeing the mixing effect between oxygen and the solution and ensuring the leaching effect of the solution.

Detailed Implementation

[0039] All embodiments of the present invention are intended to fall within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0040] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating that the purpose, technical solution, and advantages of the method are clearer. The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort indicate or imply the relative importance of the indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] Reference Figures 1-8As shown, a reaction vessel for processing arsenic filter cake includes: a high-pressure vessel body 10, the discharge end of which is connected to an adjusting tank; at least one slurry inlet 20 is provided at the top of the high-pressure vessel body 10; several stirring structures 30 are provided at the top of the high-pressure vessel body 10; a stirring rod 31 is connected to the lower end of each stirring structure 30; several oxygen feed pipes 40 are provided at the bottom of the high-pressure vessel body 10; and a lower extension structure 50 includes a long through pipe 51 disposed in the lower half of the interior of the high-pressure vessel body 10. A lower connecting member 52 is provided inside the long through pipe 51. The lower connecting member 52 rotates under the action of oxygen output from the oxygen feed pipes 40. The lower connecting member 52 is connected to a conversion member 53. A bottom swing member 54 is provided at the top of the conversion member 53. When the lower connecting member 52 rotates, it drives the conversion member 53 to rotate, thereby causing the conversion member 53 to drive the bottom swing member 54 to swing. The top of the swinging component 54 is fitted onto the bottom of the stirring rod 31; the linkage stirring structure 60 includes a transverse rotating shaft 61 located at both ends of the conversion component 53 and inside the long tube 51, and a stirring component 62 is fixedly connected to the transverse rotating shaft 61. The stirring component 62 is located in the middle of the projection position of the two stirring structures 30 and extends to the outside of the long tube 51; the multi-channel mixing structure 70 has a hollow stirring part of the stirring rod 31, and a plurality of first mixing ports 71 are opened at the lower end of the stirring part. A plurality of second mixing ports 72 are opened on the outside of the bottom swinging component 54, and a plurality of third mixing ports 73 are opened on the outside of the stirring component 62. The high-pressure oxygen input by the oxygen feed pipe 40 is driven to rotate the connecting component 52 and is then transported to the interior of the high-pressure vessel 10 through the first mixing ports 71, the second mixing ports 72, and the third mixing ports 73 respectively. The top of the high-pressure vessel 10 is provided with a waste gas conduction valve 74.

[0042] In this embodiment, the oxygen pressure leaching method used is a circulating type, that is, the entire high-pressure autoclave 10 is not sealed, but circulating, that is, high-pressure oxygen is continuously introduced, and the waste generated during leaching is continuously discharged through the waste gas conduction valve 74, so as to achieve the effect of continuous leaching.

[0043] The existing reactors are quite long. If the stirring structures are arranged over a long distance, large blank areas of slurry may remain inactive, resulting in insufficient leaching and limited overall utilization of the slurry. If they are arranged over a short distance, they may be too dense. Therefore, this invention first uses a lower extension structure 50 to set a long pipe 51 at the lower end of the reactor body, which is approximately the same length as the reactor body. A lower connecting member 52 is set in the long pipe 51. The lower connecting member 52 is driven by oxygen to move and rotate the bottom swing member 54, thereby greatly extending the stroke of the entire stirring structure 30. This avoids instability caused by long-distance control at a remote end. The pumping force of the high-pressure oxygen input provides the force at the lower end, eliminating the need for additional power structures in the high-pressure reactor body 10, which already contains harmful substances, thus ensuring the purity of the reactants during the reaction process.

[0044] The upper end of the long tube 51 actually needs space for placing the bottom swing member 54, so a conventional long tube 51 cannot be used. Therefore, the long tube 51 in this embodiment includes a long tube 511. The upper end of the long tube 511 is provided with several flat surfaces 512. Several mounting grooves for installing the stirring member 62 are provided at intervals on the long tube 511. The top surface of the long tube 51 is a flat surface 512. The flat surface 512 is used to place the bottom swing member 54, which can make the rotation of the bottom swing member 54 more stable. In addition, the long tube 511 is segmented, so it can be used to install the bottom swing member 54 and the stirring member 62.

[0045] Since there are multiple sets of high-pressure oxygen inlets, multiple sets of structures connecting to the high-pressure oxygen inlets also need to be set in the long pipe 51. Therefore, in this embodiment, the lower end of the long pipe 51 is connected to several lower extension pipes 55. The lower connecting member 52 includes a positioning ring groove 521 connected inside the lower extension pipe 55. A rotating ring 522 is movably arranged inside the positioning ring groove 521. An air ring 523 is arranged inside the rotating ring 522. When high-pressure oxygen rushes into the air ring 523, the air ring 523 rotates. An active wheel frame 524 is connected to the top of the air ring 523. The active wheel frame 524 is connected to the conversion member 53. Several lower extension pipes 55 are arranged inside the long pipe 51. The air ring 523 inside the lower extension pipe 55 can rotate when high-pressure oxygen is introduced, and when it rotates, it drives the rotating ring 522, thereby serving as the power for the bottom swing member 54 and the stirring member 62.

[0046] The wind ring 523 cannot be directly used as a power source. It requires other transfer structures when transmitting power to other components. Therefore, the active wheel frame 524 in this embodiment includes a hollow tube 5241 connected to the outer edge of the rotating ring 522. The top of the hollow tube 5241 extends into the long tube 51. A conical tooth surface 5242 is connected to the top of the hollow tube 5241. The conical tooth surface 5242 meshes with the conversion element 53. The bottom surface of the active wheel frame 524 is connected to the rotating ring 522. When the rotating ring 522 rotates, it can drive the active wheel frame 524 to rotate, thereby changing the direction of the entire rotational power transmission. Furthermore, with the help of the conical tooth surface 5242, it can be set as a connecting force on the inclined plane, so that it can cooperate with the conversion element 53.

[0047] However, the conversion element 53 in this invention is not simply a one-sided conversion, but rather a multi-directional conversion. Specifically, the conversion element 53 in this embodiment includes two side bevel gears 531 connected to the inclined surface of the bevel tooth surface 5242. An upper conical wheel 532 is spaced apart on the inclined surface at the upper end of the side bevel gears 531. The upper conical wheel 532 is connected to the hollow tube 5241 through a through pipe 533. The upper conical wheel 532 is connected to the lower end of the bottom swinging member 54. The conversion element 53 first needs to transmit the rotational force to the axial position of the long tube 511 through the two side bevel gears 531, so as to drive the stirring member 62 to rotate. Secondly, it also needs to transmit the rotational force to the position of the upper conical wheel 532 through the through pipe 533, so as to drive the bottom swinging member 54 to rotate. Therefore, the conversion element 53 of this invention can convert the force into at least three directions. The distributed rotation method can save more design space and the simplified structure can effectively reduce costs and avoid more failures.

[0048] Because the pressure vessel body 10 is quite deep, the stirring structure 30 cannot extend too deeply. Therefore, the bottom oscillating member 54 in this embodiment includes a lower moving plate 541 embedded in the flat surface 512. The bottom surface of the lower moving plate 541 is in contact with the top surface of the upper conical wheel 532. A stirring plate 542 is provided at the upper end of the lower moving plate 541. Several stirring rods 543 are provided on the outer side of the stirring plate 542. The bottom oscillating member 54 is used to make up for this shortcoming. The bottom oscillating member 54 is connected to the upper conical wheel 532 through the lower moving plate 541. The upper conical wheel 532 is driven to rotate the lower moving plate 541, but at the same time, it does not interfere with the stirring structure 30. In order to better regulate the rotation of the stirring structure 30, a receiving sleeve 544 is provided on the top of the stirring plate 542 in this embodiment. The receiving sleeve 544 is located at the lower end of the stirring rod 31. The receiving sleeve 544 is also provided on the top of the stirring plate 542. The stirring rod 31 is supported by the receiving sleeve 544, thereby ensuring that the end of the stirring rod 31 can be limited to a certain extent and thus regulate the rotation.

[0049] Furthermore, based on the lower extension structure 50, the present invention also drives the entire linkage stirring structure 60 through the lower connecting member 52 and the conversion member 53, thereby setting a separate stirring member 62 between two adjacent stirring structures 30, so as to ensure that the stirring area is reasonably spaced inside the high pressure vessel 10, and can be fully leached in a high pressure oxygen environment.

[0050] When the agitator 62 rotates, it needs to ensure the sealing of the inside of the long pipe 51 while also having a certain agitation effect. Therefore, the agitator 62 in this embodiment includes an inner connecting ring 621 sleeved on the transverse rotating shaft 61. An outer connecting ring 622 is provided on the outside of the inner connecting ring 621. The inner connecting ring 621 closes the mounting groove, and a plurality of agitator handles 623 are provided on the outside of the outer connecting ring 622. The agitator 62 is provided with an inner connecting ring 621 for closing the mounting groove of the long pipe 51. The inner connecting ring 621 is then connected to the outer connecting ring 622. The agitator handles 623 are set through the outer connecting ring 622 so that the agitator handles 623 can agitate the water, thereby ensuring the sealing of the inside of the long pipe 51 during the entire high-pressure oxygen intake process, preventing the solution from intervening and affecting the driving effect of oxygen on the air ring 523, while also allowing the agitator 62 to have an agitation effect.

[0051] After using high-pressure oxygen as a power source, how to mix it evenly and quickly with the solution inside the high-pressure vessel 10 is also a point that needs to be paid close attention to under oxygen pressure leaching conditions. Therefore, in this case, in addition to the lower extension structure 50 and the linkage stirring structure 60, a multi-stage mixing structure 70 is set up to ensure that oxygen can be output from different points, thereby ensuring the mixing effect of oxygen and solution, and thus ensuring the leaching effect of solution.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
