Description

Technical Field

[0001] The present invention relates to the technical field of precious metal determination, and specifically provides a method for determining the content of precious metals in an aluminum sulfate solution. Background Art

[0002] Aluminum sulfate solution has a wide range of applications in multiple fields, mainly including the following aspects: water treatment: Aluminum sulfate solution is commonly used as a flocculant, which can flocculate with suspended solids and colloidal substances in water to form larger precipitates, thereby purifying water quality; paper industry: In the papermaking process, aluminum sulfate solution is used as a sizing agent and filler retention agent, which can improve the water resistance, strength and smoothness of paper, and improve the printing and writing performance of paper; printing and dyeing and textiles: In the printing and dyeing process, aluminum sulfate solution is used as a mordant to help dyes better adhere to fibers, improving the fastness and brightness of dyeing; agriculture: Aluminum sulfate solution can adjust the pH value of soil, improve soil structure, increase soil fertility and water retention capacity. At the same time, aluminum sulfate solution is also used to manufacture raw materials such as alum and aluminum white, petroleum decolorization and deodorization, and the production of certain drugs.

[0003] Although existing aluminum sulfate solutions can be used in multiple fields, there are waste liquids after the use of aluminum sulfate solutions, and these waste liquids need to be uniformly recovered and treated. However, due to the different usage objects of aluminum sulfate solutions in different fields, there are small amounts of precious metals in some waste liquids. If the precious metals are to be refined, it is necessary to detect the precious metals in the aluminum sulfate solution in advance. Although existing spectrometer equipment can effectively detect precious metals in the solution, there are still obvious defects in actual use, such as:

[0004] Currently, when using a spectrometer to detect a solution, it is usually necessary to fill several test tubes with multiple solutions to be detected, and then use a thin liquid extraction tube to draw the solution into the equipment for detection. In this way, it is necessary for the staff to prepare a large number of test tubes at one time, and it is also necessary to manually put the extraction tubes into and take them out of the test tubes one by one, resulting in a very cumbersome and laborious detection process. Moreover, the test tubes need to be cleaned after the detection, which cannot meet the current usage requirements;

[0005] Therefore, a device for determining the content of precious metals in an aluminum sulfate solution that is convenient to use is now designed to solve such defects. Summary of the Invention

[0023] The present invention provides a method for determining the precious metal content in aluminum sulfate solution. Compared with the existing technologies, the following beneficial effects are achieved:

[0024] (1) The method for measuring the precious metal content in the aluminum sulfate solution, by using the detection lifting mechanism and the solution loading mechanism in combination. The settings of these two mechanisms can insert several test tube bodies into the inner part of the cylindrical sleeve, and then utilize the power when the electric telescopic rod rises and the cooperation among various structures to drive the overall concave-shaped moving frame and several test tube bodies to move automatically horizontally while completing the liquid extraction detection. Thus, it is not necessary for the staff to manually draw the liquid pipe and shift the test tubes. During the detection process, the previous test tube can also be flipped to pour out the waste liquid inside, facilitating the subsequent cleaning by the staff, improving the detection efficiency, and meeting the current usage requirements.

[0025] (2) The method for measuring the precious metal content in the aluminum sulfate solution, by installing a horizontal moving seat on the left side of the inner cavity of the equipment box using a horizontal guide rod, and installing a supporting bottom plate on the top of the horizontal moving seat using a U-shaped sliding frame, and using an inclined surface frame, a rotation-blocking frame and a round-headed column in combination. The settings of these structures can make the rotation-blocking frame and the inclined surface plate flip to the bottom of the supporting bottom plate and the round-headed column when the liquid extraction pipe descends to extract the solution. Then, when the electric telescopic rod rises, the rectangular insertion block can be inserted into the rectangular insertion port first, and then the extrusion of the round-headed column by the inclined surface frame and the inclined surface plate can drive the supporting bottom plate and the overall concave-shaped moving frame to move leftward, so that several test tube bodies can automatically move to the bottom of the liquid extraction pipe without too much manual operation by the staff, facilitating the solution extraction. And after the electric telescopic rod rises to the top, the rotation-blocking frame and the inclined surface plate can be reset, facilitating the subsequent continuous operation.

[0026] (3) The method for measuring the precious metal content in the aluminum sulfate solution, by installing several L-shaped support frames on the top of the upper top plate, and installing a cylindrical sleeve and an L-shaped pulling frame inside the L-shaped support frames, and using an arc-shaped insertion plate and a pipe pressing part in combination. The settings of these structures can, when the test tube body is on the left side, utilize the power when the electric telescopic rod descends to extract the liquid to push the arc-shaped insertion plate to insert into the L-shaped pulling frame first to drive the cylindrical sleeve to drive the test tube body to tilt initially, and then use the pipe pressing part to press the test tube body for further rotation to make the opening face downward, so as to pour out the solution inside and discharge it from the liquid discharge port, facilitating the subsequent cleaning of the test tube body by the staff.

[0027] (4) The method for measuring the precious metal content in the aluminum sulfate solution is used by installing an arc-shaped toothed plate inside the strip-shaped frame and matching it with round-headed teeth. The setting of these structures can limit the concave-shaped moving frame during its movement, allowing the concave-shaped moving frame to only drive the test tube body to move leftward, ensuring the stability during use. And when the concave-shaped moving frame reaches the leftmost side, the clamping groove plate can be clamped with the arc-shaped block plate by using the inclined surface seat, so that the arc-shaped toothed plate descends and separates from the round-headed teeth, enabling the concave-shaped moving frame to be pulled out of the equipment box to the right. After the concave-shaped moving frame is pulled out, the L-shaped pressing rod can press the arc-shaped block plate to raise and restore the arc-shaped toothed plate, facilitating the next use and improving the overall practicality and functionality of the equipment.

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] Please refer to Figures 1 - 15 , the present invention provides a technical solution: a method for determining the precious metal content in aluminum sulfate solution, specifically including the following steps:

[0046] S1. Sample placement: Insert the test tube body 207 filled with the solution into the inside of the cylinder sleeve 206;

[0047] S2. Test tube correction: Manually push the concave-shaped moving frame 201 to slide on the top of the strip-shaped frame 130, and make the first test tube body 207 on the left face the liquid extraction tube 105;

[0048] S3. Solution extraction and detection: Use the electric telescopic rod 102 to push the liquid pump 103 downward to extract the solution;

[0049] S4. Test tube displacement: Use the upward stroke of the electric telescopic rod 102 to drive the overall displacement adjustment of the concave-shaped moving frame 201 and the test tube body 207;

[0050] S5. Solution pouring: Use the arc-shaped insertion plate 118 and the pressure tube part 119 to turn and pour the test tube body 207;

[0051] S6. Equipment reset: After completing all detections, move the concave-shaped moving frame 201 back to the far right to reset.

[0052] The above method for determining the precious metal content in aluminum sulfate solution has more specific steps as follows:

[0053] S1. Sample placement: Before use, first fill the aluminum sulfate solutions from different regions into the interiors of several test tube bodies 207 respectively, and then insert these test tube bodies 207 into the interior of the cylindrical sleeve 206 respectively, and use the frictional force and binding force inside the cylindrical sleeve 206 to fix and limit the test tube body 207;

[0054] S2. Test tube correction: After completing the placement of the test tube body 207, manually push the concave-shaped moving frame 201 to move leftward under the limiting action of the side sliding opening 135 until the first test tube body 207 on the left is directly opposite the bottom of the liquid extraction tube 105 and then stop. At this time, the round head teeth 211 also engage with the arc-shaped tooth plate 131, and the arc-shaped tooth plate 131 uses the elastic force of the fourth spring 133 to push the arc-shaped tooth plate 131 upward to prevent the concave-shaped moving frame 201 from moving rightward, and only allows the concave-shaped moving frame 201 to move leftward;

[0055] S3. Solution extraction and detection: After completing the movement of the concave-shaped moving frame 201, start the electric telescopic rod 102 to push the liquid pump 103 and the bent top plate 107 to descend synchronously. When the liquid extraction tube 105 descends to the top of the test tube body 207, at this time, the inclined panel 116 is resisted by the round head column 123 and flips, and then the inclined panel 116 descends to the bottom of the round head column 123 and then resets and is parallel to the inclined surface frame 115. When the electric telescopic rod 102 continues to descend, the liquid extraction tube 105 will be completely inserted into the inside of the test tube body 207. At this time, the bent top plate 107 uses the elastic force of the second spring 112 to push the two rotation-resistant frames 113 to contact the bottom plate 125 and turn upward when descending, and then as the electric telescopic rod 102 continues to descend, the rotation-resistant frames 113 turn back to the flat state again and are located at the bottom of the bottom plate 125. After the electric telescopic rod 102 stops descending, start the liquid pump 103 to extract the solution and transmit it to the spectrometer device 104 through the liquid delivery tube 106 for detection;

[0056] S4, test tube displacement: after the sampling test is completed, the electric telescopic rod 102 is started to pull the liquid pump 103 and the liquid suction tube 105 to rise. When the liquid suction tube 105 rises and leaves the test tube body 207, the two anti-rotation frames 113 will contact the bottom of the bottom support plate 125 and support the bottom support plate 125 to rise upward in the limit position of the slider frame 124 and the return slide frame 122. When the rectangular plug block 126 is inserted into the rectangular socket 203, the bottom support plate 125 is blocked and no longer rises, but the lifting rod 108 can still continue to rise with the electric telescopic rod 102 in the sliding relationship with the T-frame 109. The rise at this time will make the inclined plate 116 and the inclined frame 115 contact the round head column 123 and squeeze it, and the round head column 123 will use the horizontal displacement seat 12 1 and the guiding effect of the cross guide rod 120 allow the return sliding frame 122 to use the rectangular plug block 126 to drive the entire concave moving frame 201 to move one grid to the left again, so that the second test tube body 207 is located directly below the liquid extraction tube 105, and as the inclined frame 115 rises, the arc column 117 on one side of it will be inserted into the inner part of the extrusion convex frame 110, and the extrusion convex frame 110 drives the two anti-rotation frames 113 to move backward. After the anti-rotation frame 113 moves backward and disengages from the bottom support plate 125, the entire bottom support plate 125 descends in the limit of the return sliding frame 122 and disengages from the rectangular socket 203. At the same time, the inclined frame 115 continues to rise, causing the round head column 123 to slide to one side of the inclined frame 115 and lose the resistance pressure. Then, the round head column 123 pushes the bottom support plate 125 to move right again and reset through the elastic force of the third spring 127;

[0057] S5, pouring out the solution: after the test tube body 207 has completed its movement, the electric telescopic rod 102 will push the liquid pump 103 down again to perform extraction testing. This descent will drive the arc plug plate 118 to insert into the inner side of the first L-shaped puller 209 on the left side, and drive the L-shaped puller 209 to move forward under the limit of the rebound rod 208. At this time, the forward movement of the L-shaped puller 209 will pull the cylindrical sleeve 206 and the bottom end of the test tube body 207 to rotate forward. At this time, the test tube body 207 is in an inclined state. As the arc plug plate 118 continues to descend, the pressure tube part 119 will press the test tube body 207 and continue to rotate again, so that the opening of the test tube body 207 is tilted downward to pour out the solution inside, and then the solution is discharged from the liquid discharge port 129. When the electric telescopic rod 102 rises again, the arc plug plate 118 and the pressure tube part 119 no longer press the test tube body 207, and the test tube body 207 will use its own gravity to restore to a vertical state;

[0058] S6. Equipment reset: After S3, S4, and S5 are repeated several times, that is, after the last test tube body 207 has also completed extraction, at this time, the concave-shaped moving frame 201 will move to the leftmost side, and the concave-shaped moving frame 201 will press against the inclined plane seat 136 and completely press down the arc-shaped tooth plate 131, so that the clamping groove plate 134 is clamped with the arc-shaped block plate 138. After clamping, the arc-shaped tooth plate 131 retracts into the inside of the strip-shaped frame 130 and no longer meshes with the round-headed clamping teeth 211. After the last test tube body 207 has completed pouring the solution, manually pull the concave-shaped moving frame 201 back to the right side of the equipment box 101. After the concave-shaped moving frame 201 returns to the right side, the L-shaped pressing rod 204 will press the arc-shaped block plate 138 to pull out the arc-shaped block plate 138 from the inside of the clamping groove plate 134. At this time, the clamping groove plate 134 loses its limit, and several fourth springs 133 push the arc-shaped tooth plate 131 to rise and reset again.
