[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0032] The present invention provides an on-line circulating copper powder recovery device, as Figures 1 to 5As shown in the figure, it includes an outer frame 1. At the top inside the outer frame 1, there is a preliminary filtering component for recycling copper powder, and an inclined filtering component at the bottom of the preliminary filtering component. At the bottom of the right side of the outer frame 1, there is a drain port 22, and the liquid filtered by the inclined filtering component is discharged through the drain port 22. The conveying component feeds the oil liquid carrying copper powder into the preliminary filtering component. The preliminary filtering component separates large residues in the oil liquid. The filtered oil liquid carrying copper powder falls onto the top surface of the inclined filtering component. The inclined filtering component separates the copper powder from the oil liquid. The oil liquid that has undergone double filtration gradually accumulates inside the outer frame 1. At this time, the oil liquid inside the outer frame 1 is discharged through the drain port 22, and the discharged oil liquid is returned to the conveying component to ensure the circulation effect of the oil liquid.

[0033] The preliminary filtering component includes a drum 2, annularly arranged teeth 3, an inner ring 4, a limiting rod 5, and a power component for driving the drum 2 to rotate; the drum 2 is horizontally located at the top inside the outer frame 1. At the bottom of the circumferential outer surface of the drum 2, there are a plurality of leakage holes. The annularly arranged teeth 3 are located at the left side of the circumferential outer surface of the drum 2. The power component uses the plurality of teeth 3 to make the drum 2 rotate inside the outer frame 1. The inner ring 4 is inside the drum 2. The circumferential outer surface of the inner ring 4 is in spiral fit with the inner side wall of the drum 2. There are through openings on both sides of the outer frame 1, and the two ends of the drum 2 correspond to the two through openings one by one. After a long time of preliminary filtering treatment, a large amount of large residues accumulate inside the drum 2. When the power component is started and the power component uses the plurality of teeth 3 to make the drum 2 rotate, the rotating drum 2 makes the large residues tumble inside the drum 2, and the large residues centrifugally separate the oil liquid on the surface during the tumbling process. At this time, the rotating drum 2 leaks the oil liquid through the leakage holes, avoiding excessive oil liquid accumulation on the surface of the large residues.

[0034] The oil liquid carrying copper powder is fed into the drum 2 through the through opening on the left side. During the process of the oil liquid flowing inside the drum 2, the plurality of leakage holes at the bottom of the drum 2 facilitate the separation of the oil liquid and large residues, and the oil liquid drives the copper powder to fall onto the top of the inclined filtering component during the preliminary filtering process, completing the preliminary filtering treatment of the oil liquid.

[0035] At the right side of the outer frame 1, there are two opposite convex strips 6 provided with openings. The two limiting rods 5 correspond to the two convex strips 6 one by one. The left end of the limiting rod 5 is connected to the inner ring 4, the right end of the limiting rod 5 penetrates through the convex strip 6, and the right sides of the two limiting rods 5 are connected by a cross bar. Since the limiting rod 5 cooperates with the convex strip 6 to limit the inner ring 4 inside the drum 2, preventing the inner ring 4 from rotating with the drum 2, and the circumferential outer surface of the inner ring 4 is in spiral fit with the inner side wall of the drum 2, the rotating drum 2 makes the inner ring 4 move inside the drum 2.

[0036] When the rotating drum 2 causes the inner ring 4 to move rightward, the rightward-moving inner ring 4 drives the cross bar away from the outer frame 1 by means of the limiting rod 5. The rightward-moving inner ring 4 pushes the large residues inside the drum 2 to move synchronously. Until the right side surface of the inner ring 4 fits against the right inner side wall of the outer frame 1, the rightward-moving large residues are discharged from the drum 2 through the through holes on the right side, completing the rapid cleaning of the drum 2. At this time, the power component causes the drum 2 to rotate in the reverse direction. The reversely rotating drum 2 causes the inner ring 4 to move leftward until the left side surface of the inner ring 4 fits against the left inner side wall of the outer frame 1. At this time, the leakage holes on the surface of the drum 2 correspond to the inclined filtering component at the bottom.

[0037] In Figure 1 and Figure 2 the power component includes a motor 9, a squeezing roller 10 and a gear 11; the motor 9 is installed on the left side of the outer frame 1, the squeezing roller 10 is rotatably inserted inside the outer frame 1, the circumferential outer side surface of the squeezing roller 10 is in close contact with the circumferential outer side surface of the drum 2, and the squeezing roller 10 is made of rubber material. The left end of the squeezing roller 10 is drivingly connected to the output end of the motor 9 by means of the gear 11, and the gear 11 meshes with a plurality of teeth 3 on the surface of the drum 2. Start the motor 9, the output end of the motor 9 causes the squeezing roller 10 to rotate inside the outer frame 1 by means of the gear 11. Since the gear 11 meshes with the teeth 3 on the left side of the drum 2, the rotating gear 11 causes the drum 2 to rotate in the reverse direction by means of the teeth 3, that is, the rotating direction of the gear 11 is opposite to the rotating direction of the drum 2. At this time, the squeezing roller 10 and the drum 2 rotate towards each other. Until the circumferential outer side surface of the squeezing roller 10 contacts the leakage holes of the drum 2, since the circumferential outer side surface of the squeezing roller 10 is in close contact with the circumferential outer side surface of the drum 2, the squeezing roller 10 pushes the large residues inside the leakage holes back into the rotating drum 2, preventing the large residues from blocking the leakage holes on the surface of the drum 2, and the rotating drum 2 and the inner ring 4 cooperate to clean the large residues inside the drum 2, ensuring the continuous filtering effect of the drum 2 on the oil liquid.

[0038] In Figure 2 、 Figure 3 and Figure 5 both inner sides of the two through holes are provided with annular grooves 7, and a plurality of convex rods 8 are fixed on both end faces of the drum 2. When the drum 2 rotates, the rotating drum 2 rotates the convex rods 8 inside the annular grooves 7. The rotational cooperation of the plurality of convex rods 8 and the annular grooves 7 prevents the drum 2 from shifting or tilting during rotation, so that the drum 2 is always in a horizontal state.

[0039] In Figure 1 、 Figure 6 and Figure 7Among them, the inclined filtering component includes an inclined filter plate 12, a rotating rod 13, a plurality of scraping blades 14 on the surface of the rotating rod 13, side strips 15 on both sides of the inclined filter plate 12, and a pulling component for moving the rotating rod 13 downward; the inclined filter plate 12 is inclined inside the outer frame 1, the top of the inclined filter plate 12 corresponds to a plurality of leakage holes at the bottom of the roller 2, the rotating rod 13 is horizontally placed on the top surface of the inclined filter plate 12, the scraping blades 14 are made of a soft material, outer rods 16 are provided at both ends of the rotating rod 13, and inclined grooves corresponding to the outer rods 16 are provided on both side surfaces of the outer frame 1, and the pulling component uses the outer rods 16 to pull the rotating rod 13 downward. The preliminarily filtered oil drops on the top surface of the inclined inclined filter plate 12. At this time, the inclined inclined filter plate 12 filters the oil, and the oil accumulates inside the outer frame 1 through the inclined filter plate 12. The copper powder in the oil gradually accumulates on the top surface of the inclined filter plate 12. A vibrating machine is placed on the top of the outer frame 1. When the vibrating machine works, the outer frame 1 drives the inclined filter plate 12 to rotate, and when the motor 9 works, the inclined filter plate 12 can also rotate. The vibrating inclined filter plate 12 causes the copper powder to move downward on the top surface of the inclined filter plate 12. At this time, the scraping blades 14 on the surface of the rotating rod 13 do not block the downward movement of the copper powder.

[0040] Vertical grooves 21 are provided on both side surfaces of the outer frame 1, and sliding rods are fixed to both side ends at the top of the inclined filter plate 12. The rotating inclined filter plate 12 uses the sliding rods to move up and down inside the vertical grooves 21. When the top end of the inclined filter plate 12 moves downward, the pulling component uses the outer rod 16 to move the rotating rod 13 downward on the top surface of the inclined filter plate 12, and the downward moving outer rod 16 moves downward inside the inclined groove. The rotating inclined filter plate 12 uses the sliding rods to move downward inside the vertical grooves 21. When the top end of the inclined filter plate 12 moves upward, the upward moving inclined filter plate 12 uses the side strip 15 to push the outer rod 16 to move upward inside the inclined groove. The upward moving outer rod 16 pulls the pulling component during the upward movement. At this time, the top end of the inclined filter plate 12 uses the sliding rods to move upward inside the vertical grooves 21.

[0041] The pulling component includes an elastic strip 17, a plug rod 18, and an arc-shaped plate 19; the top end of the elastic strip 17 is connected to the outer circumferential surface of the plug rod 18, the inner end of the plug rod 18 is rotatably inserted into the outer end of the outer rod 16, an arc-shaped plate 19 is provided at the bottom end of the inclined groove, the bottom end of the elastic strip 17 is connected to the arc-shaped plate 19, and annularly arranged tooth grooves are provided at the inner part of the outer circumferential surface of the outer rod 16, and a rack 20 engaged with the tooth grooves is fixed to the top surface of the side strip 15. The moving outer rod 16 rolls on the top surface of the rack 20 by means of the tooth grooves.

[0042] When the top end of the inclined filter plate 12 moves downward, the pulling force of the elastic strip 17 at this time makes the outer side surface of the outer rod 16 always fit with the top surface of the edge strip 15, and the elastic force of the elastic strip 17 makes the insertion rod 18 pull the outer rod 16 to move downward inside the inclined groove. When the downward-moving outer rod 16 slides inside the inclined groove, since the tooth grooves on the surface of the outer rod 16 are engaged with the rack 20, the downward-moving outer rod 16 rolls on the top of the rack 20. At this time, the outer side rotates counterclockwise on the inner end surface of the insertion rod 18. The rotating outer rod 16 makes the plurality of scraping blades 14 rotate synchronously counterclockwise by using the rotating rod 13. The plurality of downward-moving scraping blades 14 scrape up the copper powder accumulated on the top surface of the inclined filter plate 12, and expand and disperse the copper powder accumulated on the top surface of the inclined filter plate 12.

[0043] When the top end of the inclined filter plate 12 moves upward, the inclined filter plate 12 uses the edge strip 15 to push the outer rod 16 to move upward inside the inclined groove. At this time, the outer rod 16 rotates clockwise on the surface of the rack 20 by using the tooth grooves. The rotating outer rod 16 makes the plurality of scraping blades 14 rotate synchronously clockwise by using the rotating rod 13. The plurality of upward-moving scraping blades 14 quickly scrape off the expanded and dispersed copper powder. The vibrating inclined filter plate 12 ensures that the scraped copper powder quickly moves downward on the top surface of the inclined filter plate 12, avoiding the accumulation of filtered copper powder on the top surface of the inclined filter plate 12.

[0044] Both sides of the top surface of the extrusion bin 23 are provided with sliding grooves 25. An inner rod 26 is rotatably inserted inside the sliding grooves 25. Both sides of the top of the extrusion bin 23 are provided with sliders 27, and the two sliders 27 are fixedly connected by a connecting rod. The bottom end of the inclined filter plate 12 is sleeved on the surface of the connecting rod. The bottom surface of the slider 27 is fixed with a bottom rod 28, and the bottom end of the bottom rod 28 is spirally sleeved on the surface of the inner rod 26. Connect the inner rod 26 to an external power device. The power device makes the inner rod 26 rotate. The inner rod 26 rotates inside the sliding groove 25. The spiral cooperation between the rotating inner rod 26 and the bottom rod 28 makes the bottom rod 28 drive the slider 27 to move on the top of the sliding groove 25. The moving slider 27 adjusts the movement of the bottom of the inclined filter plate 12 by using the connecting rod. By using the spiral cooperation between the inner rod 26 and the bottom rod 28, the position of the bottom end of the inclined filter plate 12 is adjusted in real time. At this time, the top end of the inclined filter plate 12 moves up and down inside the vertical groove 21 by using the sliding rod.

[0045] In Figure 1 and Figure 8 As shown in, a pressing bin 23 is arranged at the front side of the outer frame 1. A screw rod 24 is arranged inside the pressing bin 23. A stepping motor for supplying energy to the screw rod 24 is installed on the left side of the outer frame 1. The copper powder filtered by the inclined filter plate 12 enters the pressing bin 23. The stepping motor works to make the screw rod 24 rotate inside the pressing bin 23. At this time, the rotating screw rod 24 squeezes and discharges the copper powder accumulated in the pressing bin 23. At this time, the recovery of the copper powder is completed.

[0046] The working principle of the present invention:

[0047] Refer to Figures 1 to 8As shown, the conveying component passes the oil carrying copper powder into the preliminary filtering component, and the oil carrying copper powder passes into the interior of the drum 2 through the opening on the left side. During the flow of the oil inside the drum 2, the multiple leakage holes at the bottom of the drum 2 facilitate the separation of the oil and large residues. In the process of preliminary filtration, the oil drives the copper powder to fall on the top of the inclined filtering component, completing the preliminary filtration treatment of the oil.

[0048] Start the motor 9, and the output end of the motor 9 uses the gear 11 to make the squeezing roller 10 rotate inside the outer frame 1. Since the gear 11 is meshed with the teeth 3 on the left side of the drum 2, the rotating gear 11 uses the teeth 3 to make the drum 2 rotate in the opposite direction, that is, the rotation direction of the gear 11 is opposite to the rotation direction of the drum 2. At this time, the squeezing roller 10 and the drum 2 rotate in the same direction until the outer side surface of the circumference of the squeezing roller 10 contacts the leakage hole of the drum 2. Since the outer side surface of the circumference of the squeezing roller 10 is tightly fitted with the outer side surface of the circumference of the drum 2, the squeezing roller 10 pushes the large residue inside the leakage hole back into the rotating drum 2 to avoid the large residue blocking the leakage hole on the surface of the drum 2, and the rotating drum 2 cooperates with the inner ring 4 to clean the large residue inside the drum 2, thereby ensuring the continuous filtering effect of the drum 2 on the oil.

[0049] The preliminary filtering component separates large residues in the oil, and the filtered oil carrying copper powder falls on the top surface of the inclined filtering component. The inclined filtering component is used to separate the copper powder from the oil. The oil after double filtration gradually accumulates inside the outer frame 1. At this time, the oil inside the outer frame 1 is discharged through the drain port 22, and the discharged oil is returned to the conveying component to ensure the circulation effect of the oil.

[0050] The initially filtered oil falls on the top surface of the inclined filter plate 12 . At this time, the inclined filter plate 12 filters the oil, and the oil is deposited inside the outer frame 1 through the inclined filter plate 12 . The copper powder in the oil is gradually deposited on the top surface of the inclined filter plate 12 .

[0051] At this time, the inner rod 26 is rotated, and the inner rod 26 rotates inside the slide groove 25. The spiral cooperation between the rotating inner rod 26 and the bottom rod 28 enables the bottom rod 28 to drive the slider 27 to move at the top of the slide groove 25. The moving slider 27 uses the connecting rod to mobilize the bottom of the inclined filter plate 12 to move. The spiral cooperation between the inner rod 26 and the bottom rod 28 is used to adjust the position of the bottom end of the inclined filter plate 12 in real time. At this time, the top end of the inclined filter plate 12 moves up and down inside the vertical groove 21 using the sliding rod.

[0052] When the top end of the inclined filter plate 12 moves downward, the pulling force of the elastic strip 17 at this time causes the outer side surface of the outer rod 16 to always fit against the top surface of the side strip 15, and the elastic force of the elastic strip 17 causes the insertion rod 18 to pull the outer rod 16 to move downward inside the inclined groove. When the downward-moving outer rod 16 slides inside the inclined groove, since the tooth grooves on the surface of the outer rod 16 are engaged with the rack 20, the downward-moving outer rod 16 rolls on the top of the rack 20. At this time, the outer side rotates counterclockwise on the inner end surface of the insertion rod 18. The rotating outer rod 16 uses the rotating rod 13 to make multiple scraping blades 14 rotate counterclockwise synchronously. The downward-moving multiple scraping blades 14 scrape up the copper powder accumulated on the top surface of the inclined filter plate 12, and expand and disperse the copper powder accumulated on the top surface of the inclined filter plate 12.

[0053] When the top end of the inclined filter plate 12 moves upward, the inclined filter plate 12 uses the side strip 15 to push the outer rod 16 to move upward inside the inclined groove. At this time, the outer rod 16 rotates clockwise on the surface of the rack 20 using the tooth grooves. The rotating outer rod 16 uses the rotating rod 13 to make multiple scraping blades 14 rotate clockwise synchronously. The upward-moving multiple scraping blades 14 quickly scrape off the expanded and dispersed copper powder. The vibrating inclined filter plate 12 ensures that the scraped copper powder moves downward quickly on the top surface of the inclined filter plate 12, avoiding the accumulation of filtered copper powder on the top surface of the inclined filter plate 12.

[0054] The copper powder filtered by the inclined filter plate 12 enters the inside of the extrusion bin 23. The stepping motor works to make the screw rod 24 rotate inside the extrusion bin 23. At this time, the rotating screw rod 24 extrudes and discharges the copper powder accumulated in the extrusion bin 23, and at this time, the recovery of the copper powder is completed.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
