While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0017] like Figures 1 to 5 As shown, an embodiment of the present invention provides a material dissolution and extraction device, comprising: Support base 1, the upper surface of which is provided with a dissolution and extraction tank 2; A support sleeve 3 is installed on the support base 1 and located on one side of the dissolution extraction tank 2; The upper cover lifting assembly is located directly above the dissolution and extraction tank 2 and is fixedly connected to the support sleeve 3; The upper cover 4 is located directly above the dissolution and extraction tank 2 and is fixedly connected to the upper cover lifting assembly; The material frame 6 is disposed in the dissolution and extraction tank 2, and the two ends of the material frame 6 are rotatably connected to the side wall of the dissolution and extraction tank 2 via a rotating shaft 7; At least one heating device 8 is installed inside the dissolution and extraction tank 2 and located on both sides of the material frame 6; A rotary motor assembly 5 is disposed on one side of the support base 1, and the rotary motor assembly 5 is used to drive the rotary shaft 7 to rotate.

[0018] In this embodiment, the dissolution extraction tank 2 is disposed inside the support base 1 and located on the upper surface of the support base 1; two opposing mounting grooves are provided on the inner side wall of the dissolution extraction tank 2, and bearing supports are provided in each mounting groove; one end of the rotating shaft 7 is fixedly connected to the side wall of the material frame 6, and the other end is disposed on the bearing support; a rotating shaft 7 is provided at each end of the material frame 6, and the rotating shafts 7 at both ends are rotatably connected to the side wall of the dissolution extraction tank 2; one side of the dissolution extraction tank 2 is provided with an extraction liquid inlet pipe communicating with the inside of the dissolution extraction tank 2 for introducing the dissolution liquid in the external storage tank; the other side is provided with an outlet pipe and a cleaning liquid inlet pipe communicating with the inside of the dissolution extraction tank 2 for connecting the introduction and outflow of the cleaning liquid in the external storage tank; in use, the sheet-shaped material to be extracted is placed in... The material is placed into the material frame 6 and installed in the dissolution extraction tank 2. Then, the upper cover 4 is lowered to the end face of the dissolution extraction tank 2 by the upper cover lifting assembly to seal the upper end face opening of the dissolution extraction tank 2. Then, the acidic dissolution solution in the storage tank is transported to the dissolution extraction tank 2 through the external storage tank. At the same time, the rotary motor assembly 5 drives the material frame 6 to rotate through the rotating shaft 7, thereby realizing dynamic contact between the material to be extracted and the acidic dissolution solution. Under the conditions of dissolution and rinsing by the dissolution solution, the target element in the material to be extracted is effectively extracted. After extraction, the inside is cleaned with a cleaning solution. The heating device 8 is an armored heating body. The heating device 8 is used to heat the solution in the dissolution extraction tank 2, thereby accelerating the dissolution and extraction of the material in the dissolution tank.

[0019] The material dissolution and extraction device of the present invention achieves rapid extraction of target elements during the material dissolution process by dynamically contacting the material to be extracted with an acidic dissolving solution, shortening the extraction time and improving the extraction efficiency of target elements. The extraction device achieves effective extraction of materials, and the extraction rate can reach more than 90% compared with the existing static soaking extraction. At the same time, the device has the characteristics of simple structure and convenient operation, which improves the process production efficiency.

[0020] In an optional embodiment of the present invention, the upper cover lifting assembly includes: A first connector 41 and a second connector 42 are respectively disposed at both ends of the support sleeve 3 and fixedly connected to the support sleeve 3; The servo motor 43 is fixedly connected to the first connector 41; Telescopic electric cylinder 44, one end of which is fixedly connected to the output end of the servo motor 43, and the other end is fixedly connected to the second connecting member 42; The upper cover 4 is fixedly connected to the other end of the telescopic electric cylinder 44.

[0021] In this embodiment, when in use, after the material to be processed is placed into the material frame 6, the servo motor 43 drives the telescopic electric cylinder 44 to move up and down, thereby sealing the upper cover 4 with the upper end face of the dissolution and extraction tank 2, thus preventing the cleaning liquid from splashing out during the rotation of the material frame 6.

[0022] In an optional embodiment of the present invention, an arc-shaped cavity is provided on the end face of the upper cover 4 opposite to the dissolution and extraction tank 2, and the cavity has an arc-shaped structure. A sealing ring 20 is provided on the outside of the dissolution and extraction tank 2.

[0023] In this embodiment, the sealing ring 20 is disposed on the outer end face of the dissolution and extraction tank 2. The sealing ring 20 is designed to further improve the sealing performance. The arc-shaped structure design on the end face of the upper cover 4 is designed to quickly collect and return the cleaning liquid splashed onto the side wall of the upper cover 4 to the dissolution and extraction tank 2 during the rotation of the material frame 6 after sealing. At the same time, the gas generated by the heating device 8 can be quickly returned to the extractor after evaporation and condensation.

[0024] In an optional embodiment of the present invention, a condensation device is provided inside the support sleeve 3; The outer side of the support sleeve 3 is provided with an exhaust gas inlet 31 and an exhaust gas outlet 32; One end of the exhaust gas inlet 31 is connected to the dissolution and extraction tank 2, and the other end is connected to the air inlet of the condensation device. One end of the exhaust gas outlet 32 ​​is connected to the air outlet of the condensation device, and the other end is connected to the exhaust gas treatment device.

[0025] In this embodiment, one end of the exhaust gas inlet 31 is connected to the dissolution extraction tank 2 through a pipe and a solenoid valve. In use, the steam and other gases generated during the heating process of the heating device 8 enter the condensation device through the exhaust gas inlet 31. The condensation device rapidly cools the water vapor generated during the heating process and forms a liquid (condensing and refluxing nitric acid and other gases in the exhaust gas), which then flows back to the dissolution extraction tank 2 through the exhaust gas inlet 31, thereby achieving rapid separation of steam and other gases. The other gases are discharged into the exhaust gas treatment device for filtration through the exhaust gas outlet 32.

[0026] In a preferred embodiment, the upper cover 4 is provided with an exhaust gas vent, and the exhaust gas inlet 31 is connected to the dissolution and extraction tank 2 through the exhaust gas vent on the upper cover 4.

[0027] In an optional embodiment of the present invention, the rotary motor assembly 5 includes: A rotary motor 51, a reducer 52, and a magnetic coupling 53 are disposed on one side of the support base 1. The magnetic coupling 53 is rotatably connected to the output end of the rotary motor 51 via a reducer 52; The magnetic coupling 53 is located on one side of the rotating shaft 7 near the dissolution and extraction tank 2, and the rotary motor 51 drives the rotating shaft 7 to rotate through the magnetic coupling 53.

[0028] In this embodiment, the rotary motor 51 and the reducer 52 can both be fixedly mounted on one side of the support base 1 via a support frame or base. The rotary motor 51 is preferably a servo motor, and the motor and reducer structure can achieve an adjustable speed of 10~500 r / min. The rotating shaft 7 is a magnetic rotating shaft that matches the magnetic coupling 53. During use, the rotary motor 51 drives the magnetic coupling 53 to rotate through the reducer 52. The magnetic coupling 53 generates a magnetic field during its movement, thereby driving the rotation of the rotating shaft 7 in the dissolution extraction tank 2, thereby achieving isolated and sealed transmission, and further improving the sealing performance of the dissolution extraction tank 2.

[0029] In an optional embodiment of the present invention, the rotary motor assembly 5 further includes: A photoelectric proximity switch 54 is disposed on one side of the magnetic coupling 53 and fixedly connected to one side of the support base 1. A positioning block 55 is disposed on the magnetic coupling 53 opposite to the photoelectric proximity switch 54.

[0030] In this embodiment, both the photoelectric proximity switch 54 and the rotary motor 51 are electrically connected to the host computer, which remotely controls the rotary motor 51. After the process is completed, the motor will stop rotating when it receives a stop signal, but it will continue to rotate due to inertia. To accurately position the material frame 6, a protruding positioning block 55 is installed on the outer shell of the magnetic coupling 53. When the positioning block 55 rotates to the front of the photoelectric proximity switch 54, the photoelectric proximity switch is triggered, and the material frame 6 is in a horizontal position. The inner material frame locking component 62 is at the top, which facilitates disassembly and removal of the inner material frame 63. When the rotary motor 51 rotates at 0, if the photoelectric proximity switch 54 is not triggered, the rotary motor 51 will rotate slowly at a speed of 5 r / min. When it is triggered, it will stop rotating immediately, and the material frame will be in a horizontal position, thus achieving the positioning of the material frame.

[0031] The material dissolving and extraction device of the present invention, through the design of photoelectric proximity switch 54 and positioning block 55, can realize the positioning of the material frame during the extraction process, and position the material frame outlet to the top of the dissolving and extraction tank 2, so as to facilitate the removal of the residue after extraction in the dissolving and extraction tank 2 for the next batch of dissolving and extraction.

[0032] In an optional embodiment of the present invention, the material box 6 includes: A fixing frame 61 is disposed in the dissolution and extraction tank 2 and fixedly connected to the rotating shaft 7. The fixing frame 61 is rotatably connected to the side wall of the dissolution and extraction tank 2 through the rotating shaft 7. At least two first fixing holes 611 are respectively provided on two opposite sides of the fixing frame 61. An inner material frame 63 is provided inside the fixed frame 61, and a second fixed hole 631 corresponding to the first fixed hole 611 is provided on the inner material frame 63. The inner material frame locking assembly 62 is provided inside the inner material frame 63, and the two ends of the inner material frame locking assembly 62 are respectively provided with a first fixing pin 626 and a second fixing pin 627. In use, the first fixing pin 626 and the second fixing pin 627 at both ends of the inner material frame locking assembly 62 pass through the first fixing hole 611 and the second fixing hole 631 at both ends of the inner material frame 63 and the fixing frame 61, respectively, to fix the inner material frame 63 and the fixing frame 61.

[0033] In this embodiment, a connecting hole 612 is provided on each of the two opposite sidewalls of the fixing frame 61, and each connecting hole 612 is connected to a rotating shaft 7. The fixing frame 61 is mounted in the dissolution extraction tank 2 through the two rotating shafts 7 and is rotatably connected to the dissolution extraction tank 2 through the two rotating shafts 7. In use, multiple sheet-like materials to be extracted are stacked in the inner material frame 63. After the inner material frame 63 is full, the inner material frame locking assembly 62 is pressed on the sheet-like materials to be extracted, and the inner material frame 63 is fixedly connected to the two ends of the fixing frame 61 through the first fixing pin 626 and the second fixing pin 627 at both ends of the inner material frame locking assembly 62. In this embodiment, through the design of the inner material frame 63, the fixing frame 61, and the inner material frame locking assembly 62, the rapid assembly and separation of the inner material frame 63 and the fixing frame 61 can be realized, thereby achieving rapid material filling and improving production efficiency.

[0034] In a preferred embodiment, the inner material frame 63 is further provided with two folding handles 632 to facilitate the handling of the inner material frame 63 by operators.

[0035] In a preferred embodiment, each side wall of the fixed frame 61 is provided with a plurality of first liquid passage holes 613; both side walls of the inner material frame 63 are provided with a plurality of second liquid passage holes 633, and the first liquid passage holes 613 and the second liquid passage holes 633 are designed for the inflow of liquid.

[0036] In an optional embodiment of the present invention, the inner material frame locking assembly 62 includes: A first support rod 621 and a second support rod 622 disposed opposite to the first support rod 621, wherein both ends of the first support rod 621 and the second support rod 622 are provided with blocking nuts 620. A first extrusion assembly and a second extrusion assembly are sleeved on the first support rod 621 and the second support rod 622 and are slidably connected to the first support rod 621 and the second support rod 622; the first extrusion assembly and the second extrusion assembly are slidably connected to each other by two first connecting rods 625. The first fixing pin 626 is disposed on the first extrusion assembly, and the second fixing pin 627 is disposed on the second extrusion assembly; A first compression spring 623 and a second compression spring 624 are respectively sleeved on the first support rod 621 and the second support rod 622, and are disposed between the first extrusion assembly and the second extrusion assembly.

[0037] The first extrusion assembly includes: A first connecting sleeve 911 is sleeved on the first support rod 621; The second connecting sleeve 912 is sleeved on the second support rod 622; The first crossbeam 913 has one end fixedly connected to one end of the first connecting sleeve 911, and the other end of the first crossbeam 913 is fixedly connected to one end of the second connecting sleeve 912. The first crossbeam 913 is provided with a plurality of first through holes, and the first crossbeam 913 is sleeved on one end of the first connecting rod 625 through the first through holes and is slidably connected to the first connecting rod 625. A first support plate 914, one end of which is fixedly connected to the other end of the first connecting sleeve 911, and the other end of which is fixedly connected to the other end of the second connecting sleeve 912, and the first fixing pin 626 is disposed on the first support plate 914.

[0038] In this embodiment, the second extrusion assembly and the first extrusion assembly have the same structure; two first fixing pins 626 are provided, respectively located at both ends of the first support plate 914, and the first support plate 914 is also sleeved on the support rod after being connected to the connecting sleeve; both ends of the first connecting rod 625 are also provided with blocking nuts 620, which are used to prevent the first extrusion assembly and the second extrusion assembly from sliding out of the ends of the first support rod 621, the second support rod 622, and the first connecting rod 625 under the tension of the first compression spring 623 and the second compression spring 624; in use, the first fixing pin 626 on the first extrusion assembly of the inner material frame locking assembly 62 can be inserted into the first fixing hole 611 and the second fixing hole 631 at one end of the inner material frame 63 and the fixing frame 61, and the inner material frame 63 and the fixing frame 61 can be fixed by the first fixing pin 626. Then, by extruding the first extrusion assembly and the second extrusion assembly, the first extrusion assembly and the second extrusion assembly move relative to each other, thereby shortening the distance between the first extrusion assembly and the second extrusion assembly. The interval between the first fixing pin 626 and the second fixing pin 627 is shortened, allowing the entire inner material frame locking assembly 62 to be placed in the middle of the inner material frame 63. This further compresses the first compression spring 623 and the second compression spring 624. Then, the second fixing pin 627 passes through the first fixing hole 611 and the second fixing hole 631 at the other end of the inner material frame 63 and the fixing frame 61, respectively, and stops compressing the first and second compression assemblies. At this point, the first compression spring 623 and the second compression spring 624 immediately regain their elasticity. This applies two opposing tensions to the first extrusion assembly and the second extrusion assembly, causing them to move away from each other. This allows the first fixing pin 626 and the second fixing pin 627 to securely connect the inner material frame 63 to the fixed frame 61. Similarly, when separating the inner material frame 63 from the fixed frame 61, the first extrusion assembly and the second extrusion assembly can be directly squeezed to remove the inner material frame locking assembly 62 from the inner material frame 63, thereby achieving rapid separation of the inner material frame 63 from the fixed frame 61.

[0039] In this embodiment, the second extrusion assembly and the first extrusion assembly have the same structure; the first fixing pin 626 is set as two, respectively set at both ends of the first support plate 914, and the first support plate 914 is also sleeved on the support rod after being connected to the connecting sleeve.

[0040] In a preferred embodiment, the second extrusion assembly includes: A third connecting sleeve 921 is fitted onto the first support rod 621; The fourth connecting sleeve 922 is sleeved on the second support rod 622; The second crossbeam 923 has one end fixedly connected to one end of the third connecting sleeve 921, and the other end of the second crossbeam 923 is fixedly connected to one end of the fourth connecting sleeve 922. The second crossbeam 923 is provided with a plurality of second through holes, and the second crossbeam 923 is sleeved on the other end of the first connecting rod 625 through the second through holes and is slidably connected to the first connecting rod 625. The second support plate 924 has one end fixedly connected to the other end of the third connecting sleeve 921, and the other end of the second support plate 924 is fixedly connected to the other end of the fourth connecting sleeve 922. The second fixing pin 627 is disposed on the second support plate 924.

[0041] The specific working principle of the material dissolution and extraction device of the present invention is as follows: First, the plate-shaped material is placed into the inner material frame 63, then transferred into the fixing frame 61, and finally fixed using the inner material frame locking assembly 62. The upper cover lifting assembly is operated to seal the dissolution extraction tank 2. 4 mol / L nitric acid is pumped into the dissolution extraction tank 2 as the dissolution extraction solution, heated to 100℃, and the rotary motor assembly 5 is turned on at a speed of 30 r / min. The motor rotates forward for 15 minutes and then reverses for 15 minutes, alternating 10 times. The rotation is then stopped, and the extract is transferred to the next process. Subsequently, the motor rotates at 300 r / min to fling off and collect the residual liquid on the surface of the plate-shaped material, then a cleaning solution is introduced for cleaning. After cleaning, the material extraction is complete. When the material passes through the cleaning... After washing, the motor stops rotating. When the photoelectric proximity switch 54 is in an untriggered state, the system starts to rotate forward at a speed of 5 r / min. When it approaches the photoelectric proximity switch 54, it stops rotating. After opening the device cover 4, the inner material frame 63, the fixed frame 61, and the inner material frame fixing and locking component 62 are all directly above. The inner material frame 63 can be removed without unlocking the rotating motor for adjustment. After the material is extracted, the extraction device cover is opened. The operator can remove the locking structure by squeezing the first squeezing component of the inner material frame fixing and locking component 62 with one hand from one side of the extraction device. Then, the operator can grasp the folding handle 632 with both hands, lift out the inner material frame 63, and transfer the extracted material to the next process.

The specific workflow of the material dissolution and extraction system described in this invention is as follows: First, the material to be extracted is placed into the material dissolution and extraction device 901, and the upper cover 4 of the extraction device is closed and sealed by the lifting motor; then, the dissolution liquid in the extraction liquid storage tank 905 is transferred into the material dissolution and extraction device 901 by opening the relevant pump valves, and the liquid supply is stopped when the liquid level reaches the high point; the heating function of the material dissolution and extraction device 901 is turned on, and the armored heating element in the material dissolution and extraction device 901 starts heating to heat the dissolution liquid (4~6mol / L HNO3 solution) to 100°C; the low-speed rotation mode of the material dissolution and extraction device 901 is turned on, and the rotation speed is increased to 20°C according to the process requirements. The material frame rotates at a speed of ~100 r / min to achieve dynamic contact with the liquid material. After the dissolution time is reached, the solution is transferred through filter 907 to the next process by opening relevant pump valves and compressed air. After the solution transfer is completed, the rotation speed is adjusted to 200~500 r / min according to process requirements. The solution on the material is spun dry under centrifugal force and transferred to the next process. The cleaning solution in the cleaning solution storage tank 902 is transferred to the extraction device by opening relevant pump valves and compressed air. It rotates at low speed to clean the material. After cleaning, the cleaning solution is transferred to the next evaporation and concentration process. The above process is repeated, and the cleaning solution in the cleaning solution temporary storage tank 903 and the cleaning solution storage tank 902 are transferred to the extraction device in turn. It rotates at low speed to clean the material. After cleaning, it is transferred to the cleaning solution temporary storage tank 903 for the next batch of cleaning. The top cover 4 of the material dissolution and extraction device 901 is opened by the lifting motor of the material dissolution and extraction device 901, and the extracted material is taken out and sent to the waste warehouse to complete the material extraction process.
