Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] like Figure 1-4 As shown, in this embodiment, a PCB metal recycling device includes a box body 1, a stirring component 2 and a crushing component 3, wherein the stirring component 2 is arranged in the box body 1, and the crushing component 3 is arranged in the box body 1;

[0028] In specific implementation, water source is input, and then flotation agent is added through the operation port 5, and then two groups of hydraulic rods 202 are synchronously started. The two groups of hydraulic rods 202 drive the rotating block 203 to move, thereby driving multiple groups of folding rods 204 to rotate and rise and fall, thereby driving the rotating shaft 205 to rise and fall under the limit of the limit frame 201. The up and down lifting of the rotating shaft 205 drives the gear 206 at one end to mesh and rotate with the tooth plate 207, and the rotating shaft 205 is immediately driven to rotate. The rotating shaft 205 rotates and drives the stirring plate 208 to rotate during the lifting process. The flotation agent is evenly dispersed through the up and down rotation and stirring of multiple stirring plates 208, thereby ensuring the contact efficiency between the metal and non-metal particles and the flotation agent.

[0029] In addition, it should be noted that each structure of the stirring assembly 2 has been treated for corrosion and water resistance.

[0030] like Figure 3 As shown, further, support plates 209 are fixedly connected to both sides of the two limit frames 201 , and two groups of support plates 209 are fixedly connected to the inner walls of the box body 1 on both sides.

[0031] During specific implementation, the limiting frame 201 can be fixed by providing the supporting plate 209 .

[0032] like Figure 1 and Figure 2 As shown, further, a sealing plate 4 is slidably connected inside the box body 1 , an operation opening 5 is opened on the outer side of the box body 1 , and a sealing door 6 is slidably connected inside the operation opening 5 .

[0033] During specific implementation, by setting a sealing plate 4, the drainage box and the box body 1 can be separated. After the metal fragments are cleaned, the sealing plate 4 is pulled open, and the solid-liquid mixture flows into the discharge box 9 for filtration and then discharged. By setting a sealing door 6 and an operating port 5, the sealing door 6 can be pulled open, and the metal fragments floating on the water surface can be cleaned through the operating port 5.

[0034] like Figure 1 As shown, further, a water inlet pipe 7 and a drain pipe 8 are fixedly connected to the outer side of the box body 1.

[0035] In specific implementation, water can be input by setting a water inlet pipe 7, and residual waste water inside can be discharged from the box body 1 by setting a drain pipe 8. It should be noted that when the solid-liquid mixture is discharged from the device through the discharge box 9, the drain pipe 8 is closed.

[0036] like Figure 1 and Figure 2 As shown, further, a discharge box 9 is fixedly connected to the bottom of the box body 1, and a filter plate 10 is fixedly connected inside the discharge box 9.

[0037] During specific implementation, the sealing plate 4 is opened, and the solid-liquid mixture flows into the discharge box 9, and is filtered by the filter plate 10 in the discharge box 9 and then discharged from the device.

[0038] Embodiment 2

[0039] On the basis of the first embodiment, in order to solve the problem of crushing the PCB board in the first embodiment, a crushing assembly 3 is provided.

[0040] like Figure 4 As shown, the crushing assembly 3 includes a crushing box 301 and a motor 302; the crushing box 301 is arranged on the box body 1; the motor 302 is fixedly connected to one side of the crushing box 301, and the driving end of the motor 302 extends into the crushing box 301 and is fixedly connected to the crushing roller 303.

[0041] During specific implementation, the motors 302 on both sides are started, and the two motors 302 respectively drive the two crushing rollers 303 to rotate relative to each other to crush the PCB board.

[0042] Working principle: First, the PCB board is crushed by the crushing assembly 3, and the crushed pieces fall into the box 1, and then water is input through the water inlet pipe 7, and then the flotation agent is added through the operation port 5, and then the two groups of hydraulic rods 202 are synchronously started, and the two groups of hydraulic rods 202 drive the rotating block 203 to move, thereby driving the multiple groups of folding rods 204 to rotate and rise, and then driving the rotating shaft 205 to rise and fall under the limit of the limit frame 201. The rotating shaft 205 rises and falls, driving the gear 206 at one end to mesh and rotate with the tooth plate 207, and the rotating shaft 205 is immediately driven to rotate, and the rotation of the rotating shaft 205 drives the stirring plate 208 to rise and fall. The flotation agent is evenly dispersed by the up and down rotation and stirring of multiple stirring plates 208, thereby ensuring the contact efficiency between the metal and non-metal particles and the flotation agent. Bubbles are generated in the water by mechanical stirring, and the flotation agent will cause the metal particles to adhere to the bubbles. As the metal particles combine with the bubbles, the density is reduced, and these particles will float to the water surface, while the non-metal particles will not float due to their high density, thereby achieving the separation of metal and non-metal, cleaning the metal powder floating on the water surface, and then pulling open the sealing plate 4, the solid-liquid mixture flows into the discharge box 9, and is filtered through the filter plate 10 in the discharge box 9 and discharged from the device.
