Their output is small and their price is expensive. Used waste catalysts can be recovered by roasting and reused.

[0003] According to a device for recovering and processing precious metal palladium in waste catalysts proposed in announcement number (CN218811984U), the stirring assembly includes a rotating motor installed on the outer top surface of the shell, a telescopic shaft fixed to the output shaft of the rotating motor and a plurality of stirring blades evenly distributed on the telescopic shaft, the telescopic shaft is located inside the shell and can extend into the processing furnace. By placing the processing furnace and the recovery box inside the shell, it is also convenient to take the processing furnace out of the shell at the first opening, and to take the recovery box out of the shell at the second opening, thereby facilitating the taking and placing operations after the precious metal palladium recovery treatment of the waste catalyst.

[0004] However, during the stirring process of the multiple stirring blades in the above-mentioned patent, the stirring blades can easily stir the precious metals to be filtered to the corners of the processing furnace, resulting in a large amount of precious metals piling up together. When a large amount of precious metals piling up at the corners, the filtering effect will deteriorate. Therefore, a device for recovering precious metals from waste catalysts is proposed to solve the above problem. Utility Model Content

When a large amount of precious metals accumulates at the corners, the filtering effect will be deteriorated.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A device for recovering precious metals from waste catalysts, comprising a box body, a separation box being arranged inside the box body, a guide assembly being arranged below the separation box, a fixing seat being fixedly installed on one side of the separation box, a connecting rod being movably sleeved on the outer side of the fixing seat, a connecting shaft being arranged at the other end of the connecting rod, the other end of the connecting rod being movably sleeved on the connecting shaft, a second motor being fixedly installed on one side of the box body, an output end of the second motor rotatingly passing through the box body and fixedly sleeved with a linkage rod, the other end of the linkage rod also being movably sleeved on the connecting shaft, a crushing assembly being arranged on the top side of the box body, and a separation assembly being arranged inside the separation box.

[0010] In one embodiment, the output end of the first motor and one end of the rotating rod are respectively fixedly sleeved with a first pulley and a second pulley, and a same belt is arranged between the first pulley and the second pulley.

[0011] In one embodiment, the separation assembly includes a separation box with a filter plate disposed therein, a plurality of ion exchange resins are fixedly mounted on the inner wall of the bottom side of the separation box, and the plurality of ion exchange resins are located below the filter plate.

[0012] In one embodiment, a first hose is fixedly installed on the top side of the separation box, the other end of the first hose passes through the box body and is connected to the crushing box, a liquid inlet is fixedly installed on one side of the box body, the other end of the liquid inlet extends to the box body and is fixedly connected to a second hose, the second hose is connected to the liquid inlet, and the other end of the second hose is fixedly connected to one side of the separation box and is connected to the separation box.

By placing the waste catalyst in the crushing box 2, and then starting the first motor 4 to drive the first pulley 5 fixedly sleeved on the output end to rotate, because the first pulley 5 and the second pulley 7 share the same belt 8, when the first pulley 5 rotates, it drives the second pulley 7 to rotate, so that the active column 9 and the driven column 10 rotate relative to each other, so that some larger waste catalysts can be crushed, which is convenient for better separation later. After the waste catalyst is crushed, it will fall into the separation box 11 along the first hose 14, and after the waste catalyst is crushed, the crushed catalyst can be better in contact with aqua regia, so that the attached precious metals can be better separated.

[0024] according to Figure 2 and Figure 3As shown, the guide assembly includes two slides 13 fixedly installed on the inner wall of the box body 1, and the two slides 13 are both provided with slide grooves. Two sliders 12 are fixedly installed on the bottom side of the separation box 11, and the two sliders 12 are respectively slidably set in the slide grooves opened by the two slides 13. Through the set sliders 12 and sliders 13, when the separation box 11 moves back and forth, the two sliders 12 fixedly installed on the bottom side of the separation box 11 will move in the slide grooves opened by the sliders 13, which can play a guiding and limiting role when the separation box 11 moves, so that it can only move in the direction of the slide groove.

[0025] according to Figure 3 and Figure 2 As shown, a first hose 14 is fixedly installed on the top side of the separation box 11, and the other end of the first hose 14 passes through the box body 1 and is connected to the crushing box 2. A liquid inlet 15 is fixedly installed on one side of the box body 1, and the other end of the liquid inlet 15 extends to the box body 1 and is fixedly connected to a second hose 16, and the second hose 16 is connected to the liquid inlet 15. The other end of the second hose 16 is fixedly connected to one side of the separation box 11 and is connected to the separation box 11. A discharge pipe 19 is fixedly installed on the bottom side of the separation box 11, and an electromagnetic valve 20 is arranged on the outside of the discharge pipe 19. A collecting box 21 is placed on the inner wall of the bottom side of the box body 1, and the collecting box 21 is located below the discharge pipe 19. Tube 16, when the separation box 11 moves left and right, because the first hose 14 and the second hose 16 are made of rubber and have a certain degree of tensile resistance, it can ensure that the first hose 14 and the second hose 16 will not be pulled apart when the separation box 11 is shaken left and right, and when the left and right shaking is reset, the first hose 14 and the second hose 16 will also be reset accordingly, and the discharge pipe 19 will be opened by the solenoid valve 20, and then the remaining aqua regia will fall into the collection box 21 along the discharge pipe 19, and the remaining aqua regia in the collection box 21 may also be mixed with a small amount of precious metals. After all the separations are completed, the remaining precious metals in the aqua regia are separated by adding a reducing agent, which can maximize the recycling of the waste catalyst.

[0026] according to Figure 3 As shown, the separation component includes a separation box 11 in which a filter plate 17 is arranged, and a plurality of ion exchange resins 18 are fixedly installed on the inner wall of the bottom side of the separation box 11. The plurality of ion exchange resins 18 are located below the filter plate 17. When aqua regia is added into the separation box 11, the aqua regia will react with the waste catalyst, thereby separating the precious metals from the waste catalyst. Subsequently, the separated precious metals will be mixed with the aqua regia and fall onto the plurality of ion exchange resins 18 along the filter holes. At this time, through the plurality of ion exchange resins 18 arranged, the ion exchange resins 18 can fully absorb the precious metals in the aqua regia, so that the precious metals can be retained in the ion exchange resins 18.

[0027] The device for recovering precious metals from waste catalysts is connected to 220V mains electricity, and the main controller can be a conventional known device for control such as a computer.

[0028] During use: when it is necessary to extract precious metals from the waste catalyst, the waste catalyst is placed in the crushing box 2, and then the first motor 4 is started to drive the first pulley 5 fixedly sleeved at the output end to rotate. Because the first pulley 5 and the second pulley 7 share the same belt 8, the first pulley 5 rotates to drive the second pulley 7 to rotate, so that the active column 9 and the driven column 10 rotate relative to each other, so that some large waste catalysts can be crushed, which is convenient for subsequent better separation. After the waste catalyst is crushed, it will fall into the separation box 11 along the first hose 14. At this time, by When water is poured in from the liquid inlet 15, aqua regia will flow into the separation box 11 along the second hose 16. When aqua regia contacts the waste catalyst, it will react with it, thereby separating the precious metals from the waste catalyst. During the separation process, the second motor 22 is started to drive the linkage rod 23 to rotate back and forth, and the other end of the linkage rod 23 is movably sleeved on the connecting shaft 26, and the connecting shaft 26 is also movably sleeved with the linkage rod 23, and the other end of the linkage rod 23 is movably sleeved on the fixing seat 24. Therefore, when the second motor 22 drives the linkage rod 23 to rotate, it synchronously drives the connecting rod 25 to rotate. When the separation box 11 is rotated to a certain extent, the separation box 11 can move back and forth left and right. When moving left and right, the waste catalyst on the filter plate 17 can shake left and right to avoid accumulation in one position, which will make the aqua regia and the waste catalyst not contact fully, resulting in poor separation effect. After the precious metals on the waste catalyst are separated, they will flow along the filter holes opened in the filter plate 17 to the bottom inner wall of the separation box 11. At this time, through the multiple ion exchange resins 18, the ion exchange resins 18 can fully absorb the precious metals in the aqua regia, so that they can be retained in the ion exchange resins 18. After collection, the discharge pipe 19 is opened through the solenoid valve 20, and the remaining aqua regia will fall into the collection box 21 along the discharge pipe 19. The remaining aqua regia in the collection box 21 may also be mixed with a small amount of precious metals. After all the separations are completed, the remaining precious metals in the aqua regia are separated by adding a reducing agent, so as to maximize the recycling of the waste catalyst. Through the box door set on one side of the separation box 11, after the separation is completed, the ion exchange resin 18 adsorbed with precious metals can be taken away by opening the box door, and the waste catalyst accumulated on the filter plate 17 can also be cleaned.
