[0017] 2. The waste circuit board fragments or chips falling through the rectangular opening fall into the dissolving liquid containing box, the bottom plate assembly outputs power to drive the driving shaft and the second belt to rotate at the same time, the second belt drives the second pulley to move, the second pulley drives the first belt, and the first pulley drives the first pulley through the first belt. At the same time, the second pulley drives the mixing sleeve to rotate, and the mixing sleeve drives the mixing blade to rotate through the mixing blade shaft. The dissolving liquid containing box is provided with a circuit board non-metallic material dissolving liquid, and the circuit board non-metallic material dissolving liquid is in contact with the waste circuit board fragments or chips to achieve the purpose of The non-metallic materials in the scraps or chips of the waste circuit board are dissolved, and the dissolution is accelerated by the mixing blades; at the same time, the screw knob is manually turned, and the screw knob drives the installation screw and the matching bevel gear 1 to rotate, and the matching bevel gear 1 drives the matching bevel gear 2 and the mixing blade shaft to rotate, and the mixing blade shaft drives the mixing blade to rotate. When the mixing blade is parallel to the central cross-section of the dissolving liquid containing box, the dissolution effect is maximized; at the same time, as the non-metallic materials in the scraps or chips of the waste circuit board are dissolved, the precious metals in the scraps or chips of the waste circuit board are The falling dissolving liquid is placed at the bottom of the container body, and contacts the spiral three through the opening one. With the movement of the driving shaft, the universal joint two, the spiral shaft two, the spiral two, the universal joint one, the spiral shaft one and the spiral one are linked together, so that part of the dissolving liquid and the precious metals in the waste circuit board fragments or the fragments fall into the buoyancy filtering collection component through the opening one on the discharge pipe, thereby separating the precious metals in the waste circuit board fragments or the fragments from the dissolving liquid and recovering the precious metals in the waste circuit board fragments or the fragments. At the same time, with the reduction of the dissolving liquid in the container body, the dissolving liquid As the amount of dissolved liquid decreases, the liquid level of the dissolved liquid begins to drop, and the floating plate floats on the liquid level of the dissolved liquid and drops as the liquid level of the dissolved liquid drops, and the floating plate drives the opening and closing plate connecting rod and the opening and closing plate to move, so that the opening and closing plate opens the supplementary installation box, and the dissolved liquid in the liquid tank enters the dissolved liquid containing box through the connecting box and the supplementary installation box, so as to realize automatic replenishment of the dissolved liquid containing box, and as the liquid level of the dissolved liquid in the dissolved liquid containing box rises, under the action of buoyancy, the floating plate brings with it the opening and closing plate connecting rod and the opening and closing plate, so that the opening and closing plate closes the supplementary installation box;

[0018] 3. Part of the dissolved liquid and the fragments or powders of precious metals enter the filter collection box through the discharge port. The filter collection box is hollow, and part of the dissolved liquid falls to the lower end of the filter collection plate through the filter holes. As the dissolved liquid accumulates in the filter collection box, the float drives the connecting cross plate to float up, and floats the filter collection plate through the spring. The fragments or powders of precious metals gather on the filter collection plate. When the baffle plate discharge opening contacts the discharge port, the discharge port is blocked by the baffle plate discharge opening, and the dissolved liquid is prevented from falling. At this time, the top of the filter collection box is started. The air pump discharges the fragments or powders of precious metals through the discharge port and collects them. When the collection is completed, the solution in the filter collection box is discharged through the discharge pipe, and the discharge port is reopened. At the same time, as the fragments or powders of precious metals on the filter collection plate gather, the filter collection plate compresses the spring downward, and the auxiliary float contacts the surface of the solution, and increases the volume of the solution discharged. When the float is completely immersed in the solution under the action of gravity, the buoyancy is increased by increasing the volume of the solution discharged and thus the accumulation of the fragments or powders of precious metals in the filter collection plate is also accommodated.

[0056] like Figure 18-22As shown, the buoyancy filter collection assembly 3 includes a filter collection box body 3-1, a mounting sleeve 3-2, a mounting sleeve end cover 3-3, a discharge port 3-4, a discharge pipe 3-5, a discharge pipe end cover 3-6, a filter collection plate 3-7, a filter hole 3-8, a connecting cross plate 3-9, a float 3-10, a discharge opening 3-11, a discharge opening baffle 3-12, a connecting slide column 3-13, an auxiliary float 3-14, and a spring 3-15. The filter collection box body 3-1 is fixedly mounted with a mounting sleeve 3-2, the mounting sleeve 3-2 is fixedly mounted with a mounting sleeve end cover 3-3, the discharge pipe 2-7 is mounted in the mounting sleeve 3-2, the mounting sleeve 3-2 is provided with a discharge port 3-4, and the discharge port 3-4 is aligned with the opening 2-10 is connected, a filter collecting plate 3-7 is slidably installed in the filter collecting box 3-1, and the filter collecting plate 3-7 is slidably connected to the connecting cross plate 3-9 through the connecting slide column 3-13, and a spring 3-15 is arranged between the connecting cross plate 3-9 and the filter collecting plate 3-7, an auxiliary float 3-14 is fixedly installed on the connecting slide column 3-13, a drain pipe 3-5 is fixedly installed on the filter collecting box 3-1 and sealed by the drain pipe end cover 3-6, a discharge opening baffle 3-12 is installed on the filter collecting plate 3-7, and the discharge opening baffle 3-12 can be adapted to the discharge port 3-4, a plurality of filter holes 3-8 are opened on the filter collecting plate 3-7, and a discharge port 3-4 is opened on the filter collecting box 3-1, so It is set that part of the dissolved liquid and the fragments or powders of precious metals enter the filter collection box 3-1 through the discharge port 3-4. The filter collection box 3-1 is hollow, and part of the dissolved liquid falls to the lower end of the filter collection plate 3-7 through the filter hole 3-8. As the dissolved liquid accumulates in the filter collection box 3-1, the float 3-10 drives the connecting cross plate 3-9 to float up, and floats the filter collection plate 3-7 through the spring 3-15. The fragments or powders of precious metals gather on the filter collection plate 3-7. When the baffle plate 3-12 of the baffle plate discharge opening contacts the discharge port 3-4, the discharge port 3-4 is blocked by the baffle plate 3-12 of the baffle plate discharge opening, and the falling of the dissolved liquid is prevented. At this time, the filter is started. The air pump at the top of the collection box 3-1 allows the fragments or powder of the precious metals to be discharged and collected through the discharge port 3-4. When the collection is completed, the dissolved liquid in the filter collection box 3-1 is discharged through the discharge pipe 3-5, and the discharge port 3-4 is reopened; at the same time, as the fragments or powder of the precious metals gather on the filter collection plate 3-7, the filter collection plate 3-7 compresses the spring 3-15 downward, and the auxiliary float 3-14 contacts the surface of the dissolved liquid, and increases the volume of the dissolved liquid discharged. When the float 3-10 is completely immersed in the dissolved liquid under the action of gravity, the buoyancy is increased by increasing the volume of the dissolved liquid discharged and thus adapting to the accumulation of fragments or powder of the precious metals in the filter collection plate 3-7.

[0057] Among them, the auxiliary float 3-14 is hollow, and the opening baffle 3-12 is a cone-like structure.

[0058] The filter holes 3-8 can prevent the fragments or powders of precious metals from falling, and the liquid discharge speed of the liquid discharge pipe 3-5 is much greater than the liquid inlet speed of the discharge port 3-4.
