Description

Technical Field

[0001] This invention relates to the field of copper powder processing technology, specifically to a copper powder recycling mechanism and recycling method. Background Technology

[0002] Copper powder is widely used in powder metallurgy, electronic materials, metal coatings, chemical catalysts and other electromechanical parts and electronic aerospace fields. In the process of recycling copper powder, the presence of impurities such as iron filings and dust in the copper powder makes it difficult to remove these impurities, which hinders the recycling and reuse of copper powder. In addition, the recycling equipment needs to be maintained regularly, which affects efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a reasonably designed, easy-to-use, maintenance-free copper powder recycling mechanism and method. This mechanism can remove iron filings and dust from copper powder, facilitating the recycling and reuse of copper powder, and can also clean the conveying components, thus eliminating the need for maintenance.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: it comprises a box body, supporting feet, a feed pipe, and a water outlet pipe. Supporting feet are fixed at all four corners of the bottom wall of the box body. A feed pipe is inserted and fixed to one side of the upper side wall of the box body, with its lower end flush with the inner top wall of the box body. A water outlet pipe is inserted and fixed to the center of the lower side wall of the box body, with its upper end flush with the inner bottom wall of the box body. It also includes:

[0005] A belt conveyor is located above one side of the inside of the housing and is connected to the front and rear side walls of the housing.

[0006] A magnetic belt is sleeved and fixed on the outside of the conveyor belt of the belt conveyor, and the front and rear sides of the magnetic belt are respectively arranged in the same vertical plane as the front and rear sides of the conveyor belt.

[0007] The No. 1 discharge pipe is inserted and fixed on one side wall of the box, with one end of the No. 1 discharge pipe located inside the box below the magnetic strip.

[0008] The shovel is fixed on the inner wall of one side of the box body. The shovel is located on the upper side of the first discharge pipe and abuts against the outer surface of the magnetic belt.

[0009] The cleaning mechanism is located on the other side inside the housing and is configured in conjunction with the magnetic strip.

[0010] A fixed frame is provided on the middle side inside the box body. The outer peripheral wall of the fixed frame abuts against the inner peripheral wall of the box body. A filter screen frame is provided on the upper side of the fixed frame.

[0011] A vibration mechanism is installed inside the housing and is connected to the filter screen frame.

[0012] The feeding mechanism is located inside the top wall of the housing and is suspended above the belt conveyor. The feeding mechanism is connected to the feeding pipe.

[0013] The second discharge pipe is inserted and fixed to the middle side of the other side wall of the box, and the inner end of the second discharge pipe is set in the same vertical plane as the inner wall of the box.

[0014] The lifting mechanism is located on the lower side inside the box, and the lifting mechanism is configured to cooperate with and abut against the fixed frame;

[0015] Heating rods, there are several heating rods, which are equally spaced from left to right on the upper side of the inside of the box. The heating rods are connected to an external power supply and are located on one side of the No. 1 discharge pipe.

[0016] Using the above technical solution, the water outlet pipe is sealed, and clean water is poured into the tank until it reaches the lower side of the second discharge pipe. Copper powder enters the tank through the inlet pipe. The feeding mechanism is activated, allowing a measured amount of copper powder to enter the tank. The copper powder inside the tank falls onto the magnetic belt. The belt conveyor is activated, moving the magnetic belt to the other side, causing the copper powder to fall downwards onto the filter screen frame. Iron impurities in the copper powder are adsorbed onto the magnetic belt. When the iron impurities come into contact with the scraper, they fall into the first discharge pipe and are removed through it. The copper powder that falls onto the filter screen frame is soaked in clean water. The clean water mixes with the dust in the copper powder and settles to the bottom of the tank. The copper powder remains in the filter screen frame. After cleaning, the lifting mechanism is activated on the filter screen frame. The lifting mechanism moves the fixed frame upward, which in turn moves the filter screen frame upward until it is located on one side of the second discharge pipe. At this point, the water mixed with dust passes through the filter screen frame and flows to the lower side of the box. The heating rod is then activated to dry the copper powder on the filter screen frame. After drying, the vibration mechanism is activated, causing the filter screen frame to shake. During this shaking, the copper powder moves to one side of the second discharge pipe and is then discharged through the second discharge pipe. After use, the outer ring of the magnetic strip is cleaned by the cleaning mechanism. No manual maintenance is required, preventing dust from adsorbing on the magnetic strip and affecting its magnetism.

[0017] As a further improvement of the present invention, the cleaning mechanism includes:

[0018] The lead screw consists of two screws, which are symmetrically embedded in the upper side wall of the housing. The two lead screws are connected by a synchronous pulley transmission assembly, and the two ends of the lead screws are respectively screwed to the two inner walls of the upper side wall of the housing through bearings.

[0019] The movable rods are two in number and are symmetrically suspended on the upper side of the box body. The upper end of the movable rod is inserted into the upper side wall of the box body, and the top end of the movable rod is screwed to the thread on the lead screw through a thread.

[0020] A fixing plate is suspended on the upper side inside the box body, and the front and rear sides of the upper surface of the fixing plate are fixedly connected to the lower ends of the front and rear moving rods, respectively.

[0021] The sponge brush is fixed to the lower surface of the fixing plate by Velcro, and the sponge brush is set to abut against the outer surface of the magnetic strip.

[0022] The cleaning motor is fixed to the outer wall of one side of the housing. The cleaning motor is connected to an external power source. The output shaft of the cleaning motor is fixedly connected to one end of one of the lead screws.

[0023] With the above technical solution, when the magnetic belt needs to be cleaned, the cleaning motor is started, which drives the lead screw connected to it to rotate. This lead screw drives another lead screw to rotate through the synchronous wheel transmission assembly. The two lead screws simultaneously drive the moving rod on them to move. The moving rod drives the fixed plate to move. The fixed plate drives the sponge brush to move until the sponge brush contacts the magnetic belt. Then, the belt conveyor is started in reverse, and the magnetic belt is cleaned by the sponge brush.

[0024] As a further improvement of the present invention, the vibration mechanism includes:

[0025] A rotating motor is fixed on the outer wall of the front side of the housing. The rotating motor is connected to an external power source, and the output shaft of the rotating motor is inserted into the front wall of the housing.

[0026] A rotating shaft is located inside the housing. The rear end of the rotating shaft is screwed into the rear side wall of the housing via a bearing, and the front end of the rotating shaft is fixedly connected to the output shaft of the rotating motor.

[0027] Cams, wherein there are several cams, which are sleeved and fixed on the rotating shaft, and the protrusions of the cams are configured to abut against the filter screen frame;

[0028] Insert plates, there are two insert plates, which are symmetrically fixed on both sides of the lower surface of the filter screen frame, and the insert plates are inserted into the slots on the side wall of the fixed frame;

[0029] Vibration springs, wherein there are several vibration springs, and they are fixed in equal quantities and at equal intervals on the inner bottom wall of the slots on the side wall of the fixed frame, and the upper end of the vibration springs is embedded in and fixed in the groove on the lower side wall of the insert plate.

[0030] Using the above technical solution, the rotating motor is started, and the rotating motor drives the cam to rotate through the rotating shaft. When the cam's protrusion rotates to the lower side, it pushes the filter screen frame downwards. At this time, the vibration spring is compressed. When the cam's protrusion rotates to the upper side, it causes the cam to separate from the filter screen frame. At this time, the filter screen frame moves upwards under the elastic force of the vibration spring. Thus, during the up-and-down movement of the filter screen frame, it drives the copper powder to move to one side of the No. 2 discharge pipe, which facilitates discharge.

[0031] As a further improvement of the present invention, the feeding mechanism includes:

[0032] The sealing plate abuts against the lower end of the feed pipe. The front and rear sides of the upper surface of the sealing plate abut against the inner top wall of the box, and the front and rear sides of the sealing plate are connected to the front and rear inner walls of the box.

[0033] A rotating disk is embedded in a circular groove on the top wall of the box. A lever is fixed on one side of the lower surface of the rotating disk and is movably inserted into a strip groove on the surface of the sealing plate.

[0034] The feeding motor is fixed on the outer top wall of the housing and is connected to an external power source. The output shaft of the feeding motor is inserted into the top wall of the housing and is fixedly connected to the center of the upper surface of the rotating disk.

[0035] The above technical solution involves starting the feeding motor, which drives the rotating disk to rotate. The rotating disk then drives the actuating rod to rotate. During rotation, the actuating rod moves within the strip groove on the sealing plate, thereby causing the sealing plate to move left and right. This allows the copper powder to enter the box in a quantitative and batch manner.

[0036] As a further improvement of the present invention, a guide plate is provided on one side above the magnetic strip. The guide plate is fixed on the inner wall of one side of the box and is located below the feed pipe.

[0037] The above technical solution can guide the copper powder through the guide plate, preventing the copper powder from falling between the magnetic strip and the inner wall of the box.

[0038] As a further improvement of the present invention, baffles are provided on both the front and rear sides of the guide plate. The baffles are fixed on the inner top wall of the box. The lower side of the baffles abuts against the outer surface of the magnetic strip. The front and rear side walls of the sealing plate are respectively movably inserted into the sliding grooves on the front and rear side baffles.

[0039] The above technical solution can guide the copper powder through the baffle, preventing the copper powder from getting stuck between the magnetic strip and the front and rear side walls of the box.

[0040] As a further improvement of the present invention, the lifting mechanism includes:

[0041] The rotating rods consist of two rods, which are symmetrically arranged on the lower side of the box body. The front and rear ends of the rotating rods are respectively screwed to the front and rear side walls of the box body through bearings. The two rotating rods are connected by a synchronous wheel transmission assembly.

[0042] The push rods consist of four rods, with one end of each rod symmetrically fitted and fixed to both ends of the rotating rod, and the other end of each push rod engaging with the lower side wall of the fixed frame.

[0043] The lifting motor is fixed on the outer wall of the front side of the housing. The lifting motor is connected to an external power source. The output shaft of the lifting motor is fixedly connected to the front end of one of the rotating rods.

[0044] Using the above technical solution, the lifting motor is started, which drives the rotating rod connected to it to rotate. This rotating rod drives another rotating rod to rotate through the synchronous wheel transmission assembly. The two rotating rods drive the push rods at their respective ends to rotate. When the push rod rotates to the top of the rotating rod, it drives the fixed frame to move upward until one side of the filter screen frame is located on the side of the second discharge pipe.

[0045] As a further improvement of the present invention, the lower side of the box body is provided with guide plates symmetrically on the left and right sides. The guide plates are fixed on the inner bottom wall and one side inner wall of the box body, and the guide plates are located on both sides above the water outlet pipe.

[0046] The above technical solution facilitates water diversion and prevents water from stagnating inside the tank.

[0047] As a further improvement of the present invention, a sealing plate is provided on the lower side of the box body. The two sides of the lower side wall of the sealing plate are inclined upward and abut against the guide plate. The center of the lower side wall of the sealing plate abuts against the top of the water outlet pipe. Electric push rods are provided on the front and rear sides of the left and right sides of the water outlet pipe. The piston rod of the electric push rod passes through the lower side wall of the box body and the guide plate in sequence through the sealing ring and is fixed on the lower side wall of the sealing plate. The electric push rod is connected to an external power source.

[0048] With the above technical solution, when sewage needs to be discharged, the electric push rod is activated, which drives the sealing plate to move upward, thereby facilitating the discharge of sewage.

[0049] As a further improvement of the present invention, a stirring motor is embedded in the front and rear sides of the sealing plate and the four corners of the bottom wall of the box. The stirring motor is connected to an external power source. A stirring rod is fixed on the output shaft of the stirring motor. The stirring rod is located inside the box and has several stirring blades at equal angles.

[0050] By using the above technical solution, the stirring motor is started, which drives the stirring rod to rotate. The stirring rod drives the stirring blade to rotate, and the stirring blade stirs the water, which can accelerate the mixing of water and dust in copper powder.

[0051] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0052] 1. Copper powder can be conveyed by a belt conveyor, and iron impurities contained in the copper powder can be collected during the conveying process. When not conveying, the magnetic belt can also be cleaned, and no maintenance is required afterward.

[0053] 2. After the iron removal operation is completed, the copper powder can be mixed with clean water to ensure that the dust in the copper powder is fully mixed with the clean water. Then, the mixture is passed through the filter screen to separate the dust from the copper powder.

[0054] 3. The height of the filter screen frame can be adjusted, so that after the dust is removed, the wastewater and copper powder can be separated, the copper powder can be dried, and finally discharged, which facilitates recycling. Attached Figure Description

[0103] Example 6

[0104] See Figure 1-2 , Figure 7 As shown, based on Embodiment 1, a sealing plate 20 is provided on the lower side of the interior of the box 1. The two sides of the lower side wall of the sealing plate 20 are inclined upward and abut against the guide plate 19. The center of the lower side wall of the sealing plate 20 abuts against the top of the water outlet pipe 4. Electric push rods 21 are provided on the front and rear sides of the left and right sides of the water outlet pipe 4. The piston rod of the electric push rod 21 passes through the lower side wall of the box 1 and the guide plate 19 in sequence through the sealing ring and is welded and fixed to the lower side wall of the sealing plate 20. The electric push rod 21 is connected to an external power source. A stirring motor 22 is embedded in the front and rear sides of the sealing plate 20 and the four corners of the bottom wall of the box 1. The stirring motor 22 is connected to an external power source. A stirring rod 23 is fixed to the output shaft of the stirring motor 22 by bolts. The stirring rod 23 is located inside the box 1. Several stirring blades 24 are provided on the stirring rod 23 at equal angles.

[0105] When using this invention, seal the water outlet pipe 4 and pour clean water into the box 1 until it reaches the lower side of the second discharge pipe 14. Copper powder enters the box 1 from the feed pipe 3. Start the feed motor 13-4, which drives the rotating disk 13-2 to rotate. The rotating disk 13-2 drives the actuating rod 13-3 to rotate. During the rotation, the actuating rod 13-3 moves in the strip groove on the sealing plate 13-1, thereby driving the sealing plate 13-1 to move left and right. This allows the copper powder to enter the box 1 in a quantitative and batch manner. The copper powder inside the box 1 falls onto the magnetic strip 6. Start the belt conveyor 5. The belt conveyor 5 drives the magnetic belt 6 to move to the other side, so that the copper powder falls down onto the filter screen frame 11. The iron impurities in the copper powder are adsorbed onto the magnetic belt 6. When the iron impurities come into contact with the scraper 8, they fall into the first discharge pipe 7 and are removed through the first discharge pipe 7. The copper powder that falls onto the filter screen frame 11 is soaked in clean water. Start the stirring motor 22. The stirring motor 22 drives the stirring rod 23 to rotate. The stirring rod 23 drives the stirring blade 24 to rotate. The stirring blade 24 stirs the clean water, which can speed up the mixing of clean water and dust in the copper powder.

[0106] The clean water mixes with the dust in the copper powder and settles to the bottom of the chamber 1, while the copper powder remains on the filter screen 11. After cleaning, the lifting motor 15-3 is started, which drives the connected rotating rod 15-1 to rotate. This rotating rod 15-1 drives another rotating rod 15-1 to rotate via a synchronous pulley transmission assembly. The two rotating rods 15-1 drive the push rods 15-2 at their respective ends to rotate. When the push rod 15-2 rotates above the rotating rod 15-1, it drives the fixed frame 10 to move upward until one side of the filter screen 11 is located on the side of the second discharge pipe 14. At this time, the water mixed with dust passes through the filter screen 11 and flows to the bottom of the chamber 1. The electric push rod 21 is then started, which drives the filter screen 10 to rotate. The sealing plate 20 moves upward to facilitate the discharge of sewage. The heating rod 16 is activated to dry the copper powder on the filter screen frame 11. After drying, the rotating motor 12-1 is activated. The rotating motor 12-1 drives the cam 12-3 to rotate through the rotating shaft 12-2. When the convex part of the cam 12-3 rotates to the lower side, it pushes the filter screen frame 11 downward. At this time, the vibration spring 12-5 is compressed. When the convex part of the cam 12-3 rotates to the upper side, it separates the cam 12-3 from the filter screen frame 11. At this time, the filter screen frame 11 moves upward under the elastic force of the vibration spring 12-5. Thus, during the up-and-down movement of the filter screen frame 11, the copper powder moves to one side of the second discharge pipe 14 and is then discharged through the second discharge pipe 14.

[0107] After use, start the cleaning motor 9-5. The cleaning motor 9-5 drives the connected lead screw 9-1 to rotate. The lead screw 9-1 drives another lead screw 9-1 to rotate through the synchronous pulley transmission assembly. The two lead screws 9-1 simultaneously drive the moving rod 9-2 on them to move. The moving rod 9-2 drives the fixed plate 9-3 to move. The fixed plate 9-3 drives the sponge brush 9-4 to move until the sponge brush 9-4 contacts the magnetic belt 6. Then, start the belt conveyor 5 in reverse and clean the magnetic belt 6 with the sponge brush 9-4. No manual maintenance is required, which avoids dust adhering to the magnetic belt 6 and affecting its magnetism.

[0108] Compared with the prior art, the beneficial effects of this specific embodiment are as follows:

[0109] 1. Copper powder can be conveyed by belt conveyor 5, and iron impurities contained in the copper powder can be collected during the conveying process. When not conveying, the magnetic belt 6 can also be cleaned, without the need for subsequent maintenance.

[0110] 2. After the iron removal operation is completed, the copper powder can be mixed with clean water to fully mix the dust in the copper powder with the clean water, and then passed through the filter screen frame 11 to separate the dust from the copper powder.

[0111] 3. The height of the filter frame 11 can be adjusted, so that after the dust is removed, the wastewater and copper powder can be separated, the copper powder can be dried, and finally discharged, which facilitates recycling.
