DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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.

[0038] Embodiment 1:

[0039] like Figure 1-Figure 9 As shown, an embodiment of the present invention provides a metal ion extraction device for mineral resource exploration, including a lower shell 1, a center frame 5, an upper shell 2, a sample crushing assembly 3 and a DC power supply (which is an existing conventional component, not shown in the drawings). The lower shell 1, the center frame 5 and the upper shell 2 adopt a three-section connection structure, and each part can be disassembled, so that after the metal ion extraction is completed, the center frame 5 can be quickly disassembled, thereby reducing the experimental operation steps and improving the experimental efficiency.

[0040] The top of the lower shell 1 is provided with an annular connecting portion extending outward, which is annular and has an internal thread. The center frame 5 is located on the inner side of the annular connecting portion of the lower shell 1, and the center frame 5 is placed on the step formed at the bottom end of the annular connecting portion. An electrode assembly 6 is installed on the center frame 5, and an extraction carrier 7 is fixedly connected to the bottom end of the electrode assembly 6. Generally, two groups of electrode assemblies 6 and extraction carriers 7 are provided, and the two groups of electrode assemblies 6 and extraction carriers 7 are used as positive and negative electrodes. High-density polyurethane foam can be used as the extraction carrier 7. High-density polyurethane foam has extremely strong adsorption capacity. It can be used as an extraction carrier to improve the accuracy of the experiment. The upper shell 2 includes a bottom shell 201 with an opening downward, a top shell 202 with an opening upward, and a channel shell 20 connected between the bottom shell 201 and the top shell 202 to connect the bottom shell 201 with the top shell 202. 3. The bottom shell 201, the top shell 202 and the channel shell 203 are manufactured by an integrated injection molding process. The bottom end of the bottom shell 201 is threadedly installed on the inner side of the annular connecting portion of the lower shell 1, and the upper shell 2 and the lower shell 1 are clamped to fix the center frame 5. A test chamber is formed between the bottom shell 201 and the lower shell 1. The electrode assembly 6 and the extraction carrier 7 are located inside the test chamber. A filter screen 4 is installed on the inner side of the top shell 202. The sample crushing assembly 3 is installed on the top of the top shell 202, and the sample crushing assembly 3 forms a crushing chamber inside the top shell 202. A terminal 8 is provided at the top of the bottom shell 201. The DC power supply is used to power the terminal 8. The DC power supply provides 5V-10V DC power. For example, 9V DC power extraction effect is better. The top of the electrode assembly 6 is in contact with the terminal 8, that is, the electrode assembly 6 and the terminal 8 are conductive.

[0041] The lower shell 1, the center frame 5, and the upper shell 2 are all made of non-conductive plastic material to avoid affecting the power supply during the metal ion extraction process.

[0042] When in use, first add a certain amount of extracting solution into the test chamber, the extracting solution preferably has a mass concentration of 15% nitric acid, then take a certain weight of the mineral sample to be tested and put it into the crushing chamber, power on the sample crushing component 3, the sample crushing component 3 crushes the mineral sample in the crushing chamber, and the mineral sample that meets the particle size requirement after crushing enters the test chamber through the filter 4, the mineral sample entering the test chamber and the extracting solution in the test chamber, after the mineral sample in the crushing chamber falls completely, the sample crushing component 3 can be removed, and a DC power supply is used to provide 5-10V DC power to the terminal 8, preferably 9V, and the metal ion extraction is completed after 1.5-3H, then the center frame 5 is disassembled, and the extraction carrier is removed for subsequent analysis.

[0043] The DC power supply can be a battery-type mobile power supply, which is suitable for use in the wild; the DC power supply supplies power to multiple metal ion extraction devices through wiring harnesses and switching elements, and the DC power supply can also be boosted by a transformer to supply power to the motor components 305 of the sample crushing component 3. Multiple metal ion extraction devices share one DC power supply and one sample crushing component 3, thereby reducing the cost of multiple devices.

[0044] In the first embodiment, Figure 3 As shown, the electrode assembly 6 includes a metal column 601 , a threaded cap 603 , a sliding cap 605 , a diagonal support rod 608 and a spring 609 . The metal column 601 is fixedly installed on the central frame 5, and the bottom end of the metal column 601 is connected to the extraction carrier 7. The top of the metal column 601 is fixedly provided with a threaded section 602, and the top of the threaded cap 603 is provided with a center ring hole 604. The threaded cap 603 is threadedly connected to the threaded section 602. The sliding cap 605 is slidably sleeved on the outside of the threaded cap 603, and the sliding cap 605 can slide up and down along the axis. The top of the sliding cap 605 is fixedly provided with a top plate portion 606, and the bottom of the top plate portion 606 is fixedly connected with a connecting seat 607. The top end of the diagonal support rod 608 is rotatably connected to the connecting seat 607. There are two groups of diagonal support rods 608, and the two groups of diagonal support rods 608 are distributed in an "A" shape. The bottom ends of the two groups of diagonal support rods 608 pass through the center ring hole 604, and a spring 609 is provided between the bottom ends of the two groups of diagonal support rods 608.

[0045] The above structure can be used to adjust the height of the sliding cap 605, thereby ensuring that the sliding cap 605 and the terminal 8 can be reliably in contact. The specific principle is: by tightening the threaded cap 603 downward, the central ring hole 604 at the top of the threaded cap 603 will also move downward, and the inner side of the central ring hole 604 squeezes the waist (side) of the two groups of diagonal support rods 608 distributed in an "A" shape, so that the two groups of diagonal support rods 608 distributed in an "A" shape are moved closer to the middle, that is, the inclination angle of the diagonal support rod 608 and the horizontal plane increases, and the overall height of the diagonal support rod 608 in the vertical direction increases, so that the top of the diagonal support rod 608 presses upward against the sliding cap 605, so that the sliding cap 605 moves upward, ensuring that the sliding cap 605 and the terminal 8 can be reliably in contact.

A nut is threadedly connected to the side of the metal column 601 and located above the mounting ring 502. The top of the metal column 601 passes through the through hole on the mounting ring 502 from bottom to top, and then the nut is threadedly installed to achieve fixed installation of the metal column 601 and the mounting ring 502.

There are two limiting plates 10 arranged in parallel, and the limiting frame 9 is located between the two parallel limiting plates 10. The limiting frame 9 cooperates with the limiting plate 10 to ensure that there is no relative rotation between the center frame 5 and the upper shell 2, that is, to ensure that the top of the electrode assembly 6 always corresponds to the position of the terminal 8.

[0048] In the first embodiment, Figure 8 As shown, the filter screen 4 includes a first annular portion 401, a mesh panel 403 and a plug post 402.
