[0018] Furthermore, a processing method of a copper powder recovery pre-treatment device comprises the following steps:

[0019] Step 1: After pouring the copper powder onto the filter, start the motor 1. The motor 1 drives the frame to move horizontally through the connecting rod. The connecting rod moves in the through groove at one end of the shell. At the same time, the protrusions on one side of the two ends of the frame move in the rectangular groove of the shell. The frame movement drives the filter to move horizontally, thereby accelerating the screening speed of the copper powder on the filter. By setting a shaking component, the filter can be automatically shaken to improve the automation of the device and reduce manual workload. By setting a connecting component, the positioning plate is taken by the handle, and then the filter is placed in the frame. At the same time, the positioning plate enters the positioning groove. The magnetic strip 1 at the lower end of the positioning plate is adsorbed and fixed with the magnetic strip 2 in the positioning groove to achieve the effect of limiting and fixing the filter. The positioning plate can be removed from the positioning groove by the handle, so that the filter can be taken out of the frame. By setting a connecting component, it is convenient to take the filter out of the frame, so that it is convenient to clean the copper powder that does not meet the size at the top of the filter.

[0020] Step 2: When the filter screens the copper powder, dust is generated. The suction fan is turned on. The suction fan forms a negative pressure in the dust inlet hopper through the dust reduction box and the connecting pipe. The dust enters the dust reduction box through the dust inlet hopper and the connecting pipe. The sand and gravel layer and the activated carbon layer in the dust inlet hopper filter the dust-laden air. The dust reduction component can be set to reduce the dust generated by the screening work to reduce the air pollution caused by dust. When installing the sand and gravel layer and the activated carbon layer, the sand and gravel layer and the activated carbon layer are inserted into the card slot of the dust reduction box through the installation port by setting the installation component. Then, the installation plate is taken to the installation port by the grip rod. Finally, the installation bolts are screwed into the installation holes to fix the installation plate. The installation component is set to facilitate the disassembly, cleaning or replacement of the sand and gravel layer and the activated carbon layer.

[0021] Step 3: When the device needs to be moved, turn on motor 2 to drive the screw to rotate. The rotation of the screw drives the skateboard to slide downward in the folding plate. The skateboard slides downward and the lower end of the universal wheel touches the ground, thereby lifting the device. The device can be moved by the universal wheel. When the universal wheel is not needed, the lower end of the folding plate contacts the ground. At the same time, an anti-slip pad is set at the lower end of the folding plate to play an anti-slip role. By setting a moving component, the device can be moved to different positions for use.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention sets a shaking component, and after pouring copper powder onto the filter screen, motor 1 is turned on. Motor 1 drives the frame to move horizontally through a connecting rod. The connecting rod moves in a through groove at one end of the shell. At the same time, the protrusions on one side of both ends of the frame move in the rectangular groove of the shell. The movement of the frame drives the filter screen to move horizontally, thereby accelerating the screening speed of the copper powder on the filter screen. By setting the shaking component, the filter screen can be automatically shaken, the automation of the device is improved, and the manual workload is reduced.

[0024] 2. The present invention sets a dust reduction component. When the filter screen is used to screen copper powder, dust is generated. The suction fan is turned on. The suction fan forms a negative pressure in the dust inlet hopper through the dust reduction box and the connecting pipe. The dust enters the dust reduction box through the dust inlet hopper and the connecting pipe. The sand and gravel layer and the activated carbon layer in the dust inlet hopper filter the dust-containing air. The dust reduction component can be used to reduce the dust generated by the screening work, thereby reducing the air pollution caused by the dust.

[0025] 3. The present invention sets a moving component. When the device needs to move, motor 2 is turned on to drive the screw to rotate. The rotation of the screw drives the slide plate to slide downward in the folding plate. The slide plate slides downward and the lower end of the universal wheel contacts the ground, thereby lifting the device. The device can be moved by the universal wheel. When the universal wheel is not needed, the lower end of the folding plate contacts the ground. At the same time, an anti-skid pad is set at the lower end of the folding plate to play an anti-skid role. By setting the moving component, the device can be easily moved to different positions for use. BRIEF DESCRIPTION OF THE DRAWINGS

By setting the installation component 37, the sand and gravel layer 35 and the activated carbon layer 36 are inserted into the card slot 375 of the dust reduction box 32 through the installation port 372 when the sand and gravel layer 35 and the activated carbon layer 36 are installed, and then the installation plate 371 is taken to the installation port 372 by the grip rod 373. Finally, the mounting bolts 374 are screwed into the mounting holes 376 to fix the mounting plate 371. By setting the mounting assembly 37, it is convenient to disassemble, clean or replace the sand and gravel layer 35 and the activated carbon layer 36; when the device needs to be moved, the motor 2 43 is turned on to drive the screw rod 44 to rotate. The rotation of the screw rod 44 drives the slide plate 45 to slide downward in the folding plate 41. The slide plate 45 slides downward and the lower end of the universal wheel 46 contacts the ground, thereby lifting the device. The device can be moved by the universal wheel 46. When the universal wheel 46 is not needed, the lower end of the folding plate 41 contacts the ground. At the same time, an anti-skid pad 42 is set at the lower end of the folding plate 41 to play an anti-skid role. By setting the moving assembly 4, the device can be easily moved to different positions for use.
