Description

Technical Field

[0001] The present application relates to the field of copper powder production equipment, and in particular to an integrated equipment for continuous silver coating of micron-nano copper powder. Background Art

[0002] Silver-coated copper powder is used as a very good high-conductive filler. Silver-coated copper powder is made using advanced chemical plating technology. After a specific molding and surface treatment process, a silver plating layer of different thicknesses is formed on the surface of the ultra-fine copper powder. The process of making silver-coated copper powder involves washing with deionized water to remove the acid remaining on the surface of the copper powder, filtering the deionized water to obtain clean copper powder, and other solid-liquid separation steps.

[0003] The existing equipment for solid-liquid separation includes an upper cylinder and a lower cylinder, and a filter membrane is installed between the upper cylinder and the lower cylinder. After the mixed liquid is added to the upper cylinder, the lower cylinder is vacuumed, so that a negative pressure environment is formed inside the lower cylinder, so that the liquid in the mixed liquid passes through the filter membrane and enters the lower cylinder, and the copper powder remains on the filter membrane, thereby achieving solid-liquid separation. However, after the solid-liquid separation is completed, the filter membrane needs to be manually removed and transferred to a designated location for unloading, which has a high labor cost. In addition, since the filter membrane is relatively soft in texture, the copper powder is easily separated from the filter membrane during the removal and transfer process, which is not conducive to speeding up and increasing the efficiency of copper powder production. Summary of the invention

[0004] In order to reduce labor costs and improve the production efficiency of copper powder, the present application provides an integrated equipment for continuous silver coating of micron-nano copper powder.

[0005] The present application provides an integrated equipment for continuous silver coating of micron-nano copper powder, which adopts the following technical solution: An integrated equipment for continuous silver coating of micron-nano copper powder, comprising a plurality of solid-liquid separation devices and a truss arranged corresponding to the solid-liquid separation devices, a conveying mechanism is arranged on one side of the plurality of solid-liquid separation devices, the truss is arranged across the solid-liquid separation device and the conveying mechanism, the solid-liquid separation device comprises an upper cylinder and a lower cylinder, a filter membrane is pressed between the upper cylinder and the lower cylinder, the lower cylinder is connected to a vacuum pumping device, a suction mechanism for sucking the filter membrane is arranged on the upper cylinder, a lifting mechanism for lifting the upper cylinder and a driving mechanism for driving the lifting mechanism to move along the truss are arranged on the truss, a rotatable unloading platform is arranged on the conveying mechanism, and a plurality of unloading troughs arranged in an inverted cone are arranged on the unloading platform.

[0006] By adopting the above technical solution, when in use, first, the lifting mechanism of each solid-liquid separation device lifts the upper cylinder in turn, so that the operator can place the filter membrane in turn. After the filter membrane is installed, the lifting mechanism puts the lower cylinder back to the lower limit position, and the filter membrane is pressed between the upper cylinder and the lower cylinder; after the mixed liquid is injected into the upper cylinder, the vacuum device is started, and a negative pressure environment is formed in the lower cylinder. The liquid in the mixed liquid passes through the filter membrane and enters the lower cylinder, and the copper powder remains above the filter membrane, thereby achieving solid-liquid separation. After the solid-liquid separation is completed, the lifting mechanism lifts the upper cylinder, and at the same time, the suction mechanism sucks the filter membrane and drives the filter membrane to be lifted synchronously. When the lifting mechanism is lifted to the upper limit, the driving mechanism drives the lifting mechanism to move toward the conveying mechanism and moves the filter membrane to the top of the corresponding feeding trough. Subsequently, the lifting mechanism descends and puts the filter membrane into the corresponding feeding trough to complete the taking and placing of the filter membrane. The feeding platform can be transported by the conveying mechanism, and the position of the feeding trough can be switched when the feeding platform rotates. In this way, multiple filter membranes can be collected in sequence. After completing the collection of the same batch of filter membranes, the operator will finally collect the multiple filter membranes on the unloading table to facilitate the production of the next batch of copper powder. In this application, each solid-liquid separation device is independent of each other. After the filter membrane is installed, the solid-liquid separation of the mixed liquid can be performed at the same time. Through the setting of the conveying mechanism, the unloading table and the driving mechanism, the automation of the filter membrane collection is realized, which is conducive to reducing labor costs and improving the production efficiency of copper powder.

[0008] By adopting the above technical solution, through the arrangement of the electromagnet and the magnetic conductive block, the magnetism of the electromagnet can be controlled to be on and off, so as to facilitate the suction of the filter membrane at a preset time. After the filter membrane is sucked, the filter membrane is lifted up with the upper cylinder. Since the filter membrane has a certain flexibility and the elastic reset member can be deformed after being pressed, it is convenient for the copper powder on the filter membrane to gradually gather to the center, and the middle of the filter membrane gradually sags, so that the filter membrane forms a shape with a low middle and high surroundings during the collection process, thereby reducing the possibility of copper powder spilling from the filter membrane. When the filter membrane moves to the top of the corresponding feeding trough, the lifting mechanism drives the upper cylinder to descend a certain height until the filter membrane contacts the trough wall of the feeding trough, and then the electromagnet is powered off, and the feeding table realizes the collection of the filter membrane. At the same time, the elastic reset member drives the electromagnet to reset to correspond to the position of the magnetic conductive block on the filter membrane, so as to facilitate the suction of the next batch of filter membranes after the solid-liquid separation is completed.

The upper sealing skirt, the lower sealing skirt and the sealing ring are arranged to ensure the sealing of the contact between the upper cylinder, the lower cylinder and the filter membrane, on the one hand, to avoid the possibility of leakage of the mixed liquid injected into the upper cylinder, and on the other hand, to avoid the formation of a gap between the lower cylinder and the filter membrane, which is not conducive to the formation of a negative pressure environment.

[0016] By adopting the above technical solution, the upper locking frame and the lower locking frame can be tightened by the locking bolt and the locking nut, thereby further ensuring the sealing between the upper cylinder and the upper end surface of the filter membrane, and the lower cylinder and the lower end surface of the filter membrane.

[0017] Optionally, a cleaning mechanism is provided in the upper cylinder, and the cleaning mechanism includes a water inlet assembly and a stirring assembly. The water inlet assembly includes a water inlet pipe arranged in a ring shape, and the water inlet pipe is fixed on the inner wall of the upper cylinder. The water inlet pipe is provided with a plurality of water inlet holes, and the water inlet pipe is connected to an external tap water pipe through a connecting hose.

[0018] By adopting the above technical solution, after the filter membrane is installed between the upper cylinder and the lower cylinder, the upper cylinder can also be cleaned by using a cleaning mechanism. During cleaning, water is introduced into the upper cylinder through the water inlet pipe, and then the stirring component stirs the water in the upper cylinder, thereby improving the cleaning effect of the upper cylinder.

[0024] By adopting the above technical solution, after the mixed liquid completes solid-liquid separation, the lower barrel collects the separated liquid, and after opening the liquid outlet valve, the liquid in the lower barrel can be discharged through the liquid outlet pipe. When performing solid-liquid separation, the liquid outlet valve is closed to ensure the airtightness of the lower barrel, which is conducive to the rapid formation of a negative pressure environment in the lower barrel after the vacuum device works; by setting the bottom of the lower barrel to a dome shape, the compressive strength of the lower barrel is improved, and the possibility of the lower barrel being deformed inward is reduced.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. In the present application, each solid-liquid separation device is independent of each other. After the filter membrane is installed, the solid-liquid separation of the mixed liquid can be carried out simultaneously. The filter membrane can be sucked by the suction device, and the automation of the filter membrane collection is realized through the setting of the conveying mechanism, the unloading platform and the driving mechanism, which is conducive to reducing labor costs and improving the production efficiency of copper powder.

[0026] 2. Through the setting of the electromagnet and the magnetic block, the magnetism of the electromagnet can be controlled by power on and off, so as to facilitate the absorption of the filter membrane at the preset time. After the filter membrane is absorbed, the filter membrane is lifted up with the upper cylinder. Since the filter membrane has a certain flexibility and the elastic reset part can be deformed after being pressed, the copper powder on the filter membrane gradually gathers to the center, and the middle of the filter membrane gradually sags, so that the filter membrane forms a shape with a low middle and high surroundings during the collection process, thereby reducing the possibility of copper powder spilling from the filter membrane. When the filter membrane moves to the top of the corresponding discharge trough, the lifting mechanism drives the upper cylinder to descend a certain height until the filter membrane contacts the trough wall of the discharge trough, and then the electromagnet is powered off, and the discharge table realizes the collection of the filter membrane. At the same time, the elastic reset part drives the electromagnet to reset to correspond to the position of the magnetic block on the filter membrane, so as to facilitate the absorption of the next batch of filter membranes after solid-liquid separation.

Through the setting of the leakage hole and the liquid collecting box, after the mixed liquid completes the solid-liquid separation, the copper powder on the top surface of the filter membrane appears wet mud, and a small amount of liquid droplets are attached to the bottom surface of the filter membrane. When the unloading platform collects the filter membrane, the setting of the leakage hole makes it convenient for the liquid collecting box to collect the liquid droplets remaining on the bottom surface of the filter membrane, thereby avoiding waste liquid from contaminating the surface of the unloading platform.

In this embodiment, four solid-liquid separation devices 1 are arranged; and the conveying mechanism 3 is a conventional screw slider mechanism.

[0042] Reference Figure 1-4 The solid-liquid separation device 1 includes an upper cylinder 11 and a lower cylinder 12, a filter membrane 13 is pressed between the upper cylinder 11 and the lower cylinder 12, the lower cylinder 12 is connected to a vacuum device 4, a suction mechanism 5 for sucking the filter membrane 13 is provided on the upper cylinder 11, a lifting mechanism 6 for lifting the upper cylinder 11 and a driving mechanism 7 for driving the lifting mechanism 6 to move along the truss 2 are provided on the truss 2, and a rotatable unloading platform 31 is provided on the conveying mechanism 3, and a plurality of unloading troughs 311 arranged in an inverted cone shape are provided on the unloading platform 31. In this embodiment, the unloading platform 31 is rotated by a conventional motor transmission method, and four unloading troughs 311 are provided, and the four unloading troughs 311 are arranged on the surface of the unloading platform 31 in a circumferential array.

[0043] When in use, first, the lifting mechanism 6 of each solid-liquid separation device 1 lifts the upper cylinder 11 in turn, so that the operator can place the filter membrane 13 in turn. After the filter membrane 13 is installed, the lifting mechanism 6 puts the lower cylinder 12 back to the lower limit position, and the filter membrane 13 is pressed between the upper cylinder 11 and the lower cylinder 12; after the mixed liquid is injected into the upper cylinder 11, the vacuum device 4 is started, and a negative pressure environment is formed in the lower cylinder 12. The liquid in the mixed liquid passes through the filter membrane 13 and enters the lower cylinder 12, and the copper powder remains above the filter membrane 13, thereby achieving solid-liquid separation. After the solid-liquid separation is completed, the lifting mechanism 6 lifts the upper cylinder 11, and at the same time, the suction mechanism 5 sucks the filter membrane 13, and synchronously drives the filter membrane 13 to lift. When the lifting mechanism 6 is lifted to the upper limit, the driving mechanism 7 drives the lifting mechanism 6 to move toward the conveying mechanism 3, and moves the filter membrane 13 to the top of the corresponding feeding trough 311. Subsequently, the lifting mechanism 6 descends, and the filter membrane 13 is placed in the corresponding feeding trough 311, completing the taking and placing of the filter membrane 13. The unloading platform 31 can be transported by the conveying mechanism 3, and the position of the unloading trough 311 can be switched when the unloading platform 31 rotates, so that multiple filter membranes 13 can be collected in sequence. After the collection of the same batch of filter membranes 13 is completed, the operator finally takes out the multiple filter membranes 13 on the unloading platform 31 to facilitate the production of the next batch of copper powder.

[0044] In the present application, each solid-liquid separation device 1 is independent of each other. After the installation of the filter membrane 13 is completed, the solid-liquid separation of the mixed liquid can be carried out simultaneously. Through the setting of the conveying mechanism 3, the unloading platform 31 and the driving mechanism 7, the automation of the collection of the filter membrane 13 is realized, which is beneficial to reduce labor costs and improve the production efficiency of copper powder.

A supporting mesh plate 122 is fixed to the top of the lower cylinder 12, and the top surface of the supporting mesh plate 122 is flush with the top surface of the lower flange skirt 121. An annular mounting groove 1111 is provided at the bottom of the upper flange skirt 111, and a sealing ring 1112 is installed in the mounting groove 1111. The filter membrane 13 is pressed and arranged between the sealing ring 1112 and the lower flange skirt 121. The filter membrane 13 can be supported by the supporting mesh plate 122 without affecting the liquid on the upper side of the filter membrane 13 from passing through the filter membrane 13 and entering the lower cylinder 12. By setting the upper sealing skirt, the lower sealing skirt and the sealing ring 1112, the sealing of the contact between the upper cylinder 11, the lower cylinder 12 and the filter membrane 13 is ensured, on the one hand, the possibility of leakage of the mixed liquid injected into the upper cylinder 11 is avoided, and on the other hand, the formation of a gap between the lower cylinder 12 and the filter membrane 13 is avoided, which is not conducive to the formation of a negative pressure environment.

[0046] Reference Figure 4 and Figure 6 A plurality of lower locking frames 123 are welded to the outer side of the lower flange skirt 121, and the plurality of lower locking frames 123 are evenly arranged on the outer periphery of the lower flange skirt 121. A locking bolt 124 is arranged on the lower locking frame 123, and the locking bolt 124 is rotatably connected to the lower locking frame 123 through a pin shaft 1241.

A locking nut 125 is threadedly connected to the locking bolt 124, and the bottom end of the locking nut 125 abuts against the top end of the upper locking frame 112. In this way, the upper locking frame 112 and the lower locking frame 123 can be tightened by the locking bolt 124 and the locking nut 125, thereby further ensuring the sealing between the upper cylinder 11 and the upper end surface of the filter membrane 13, and the lower cylinder 12 and the lower end surface of the filter membrane 13.

[0047] Reference Figure 4 and Figure 7The lifting mechanism 6 includes a mobile frame 61 arranged on the truss 2 and a lifting cylinder 62 installed on the mobile frame 61. The mobile frame 61 is connected to the driving mechanism 7. The lifting cylinder 62 is vertically arranged above the upper cylinder 11. The upper end outer edge of the upper cylinder 11 is welded with a connecting ear 113. The piston rod of the lifting cylinder 62 passes through the connecting ear 113 and is threadedly connected with a fastener 621. A compression spring 622 is sleeved on the piston rod of the lifting cylinder 62. One end of the compression spring 622 is connected to the connecting ear 113, and the other end is connected to the cylinder body of the lifting cylinder 62. In this embodiment, the fastener 621 is a nut. In this way, the lifting cylinder 62 can realize the lifting and lowering drive of the upper cylinder 11. The compression spring 622 can buffer the collision between the upper cylinder 11 and the lower cylinder 12 on the one hand, and can compensate the actual lifting height of the upper cylinder 11 on the other hand, so as to ensure that the upper cylinder 11 and the lower cylinder 12 are closely fitted.

[0048] Reference Figure 4 and Figure 7 The truss 2 is a double-track truss, rollers 611 are installed at both ends of the moving frame 61, and a guide groove 21 adapted to the roller 611 is provided on the inner side of the truss 2. The driving mechanism 7 includes an electric push rod 71 fixed to the truss 2, and the moving end of the electric push rod 71 is connected to the moving frame 61. The electric push rod 71 can push the moving frame 61 to move, thereby achieving the purpose of driving the upper cylinder 11 to move longitudinally. The arrangement of the roller 611 and the guide groove 21 can reduce the friction generated when the moving frame 61 moves.

[0049] Reference Figure 2 and Figure 5 , a plurality of magnetic conductive blocks 131 with magnetic conductivity are bonded to the filter membrane 13, and the plurality of magnetic conductive blocks 131 are arranged on the top surface of the filter membrane 13 in a circular array, and after the filter membrane 13 is installed, the magnetic conductive blocks 131 are located on the inner side of the upper cylinder 11, and the suction mechanism 5 includes a plurality of suction components, and the suction components include a suction bracket 51 and an electromagnet 52 arranged corresponding to the magnetic conductive blocks 131, the suction bracket 51 is fixed on the inner wall of the upper cylinder 11, and the electromagnet 52 is arranged on the suction bracket 51 along the radial sliding of the upper cylinder 11. An elastic reset member 511 is also installed on the suction bracket 51, one end of the elastic reset member 511 is connected to the innermost side of the suction bracket 51, and the other end is connected to the electromagnet 52. In this embodiment, the elastic reset member 511 is a compression spring; one section of the wire harness of the electromagnet 52 is fixed to the inner wall of the upper cylinder 11 by a buckle or a press buckle, and the other section close to the electromagnet 52 is reserved with a certain length to facilitate the electromagnet 52 to slide on the suction bracket 51.

[0050] Through the arrangement of the electromagnet 52 and the magnetic conductive block 131, the magnetism of the electromagnet 52 can be controlled to be on and off, so as to facilitate the suction of the filter membrane 13 at a preset time. After the filter membrane 13 is sucked, the filter membrane 13 is lifted along with the upper cylinder 11. Since the filter membrane 13 has a certain flexibility and the elastic reset member 511 can be deformed after being pressed, the copper powder on the filter membrane 13 is gradually gathered to the center, and the middle part of the filter membrane 13 gradually sags, so that the filter membrane 13 forms a shape with a low middle part and high surroundings during the collection process, thereby reducing the possibility of copper powder spilling from the filter membrane 13. When the filter membrane 13 moves to the top of the corresponding discharge trough 311, the lifting mechanism 6 drives the upper cylinder 11 to descend a certain height until the filter membrane 13 contacts the trough wall of the discharge trough 311, and then the electromagnet 52 is powered off, and the discharge platform 31 collects the filter membrane 13. At the same time, the elastic reset member 511 drives the electromagnet 52 to reset to correspond to the position of the magnetic block 131 on the filter membrane 13, so as to facilitate the absorption of the next batch of filter membranes 13 after the solid-liquid separation.

A stirring blade 8221 is fixed to the rod wall of the stirring rod 822, and the stirring blade 8221 is arranged so as not to interfere with the suction mechanism 5. When the stirring motor 821 is started, the stirring rod 822 is driven to rotate, and the rotation of the stirring rod 822 drives the stirring blade 8221 to rotate, thereby increasing the disturbance degree of the water in the upper cylinder 11 during cleaning, and improving the cleaning effect of the upper cylinder 11.

When performing solid-liquid separation, the liquid outlet valve 1271 is closed to ensure the airtightness of the lower tube 12, which is conducive to the rapid formation of a negative pressure environment in the lower tube 12 after the vacuum device 4 works; by setting the bottom of the lower tube 12 to a dome shape, the compressive strength of the lower tube 12 is improved, and the possibility of the lower tube 12 being deformed inwardly is reduced.

[0054] Reference Figure 9-10 , the bottom end of each feed trough 311 is formed with a leakage hole 312 after passing through the feed platform 31, and a ring-shaped liquid collecting box 32 is fixed at the bottom of the feed platform 31, and each leakage hole 312 is connected to the inside of the liquid collecting box 32, and the lower end of the side wall of the liquid collecting box 32 is connected to a drain pipe 321, and a plug 322 is installed at the outer end of the drain pipe 321. After the mixed liquid completes the solid-liquid separation, the copper powder on the top surface of the filter membrane 13 is in a wet mud state, and a small amount of liquid beads are attached to the bottom surface of the filter membrane 13. When the feed platform 31 collects the filter membrane 13, the leakage hole 312 is set, so that the liquid collecting box 32 can collect the liquid beads remaining on the bottom surface of the filter membrane 13, thereby preventing the waste liquid from contaminating the surface of the feed platform 31.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
