TECHNICAL FIELD

[0002] Silver-coated copper powder is used as a good high-conductive filler, silver-coated copper powder is formed by adopting advanced chemical plating technology, and a silver coating layer with different thicknesses is formed on the surface of superfine copper powder through specific molding and surface treatment processes. In the process of producing silver-coated copper powder, the steps of solid-liquid separation such as deionized water washing to remove acid liquid remaining on the surface of copper powder and filtering to obtain clean copper powder after deionized water are involved.

[0003] The existing solid-liquid separation equipment includes an upper cylinder and a lower cylinder, a filter membrane is arranged between the upper cylinder and the lower cylinder, after mixed liquid is added into the upper cylinder, the lower cylinder is subjected to vacuumizing treatment, so that a negative pressure environment is formed in the lower cylinder, liquid in the mixed liquid penetrates into the lower cylinder through the filter membrane, and copper powder is left above the filter membrane, thereby realizing solid-liquid separation. However, after the solid-liquid separation is completed, the filter membrane needs to be manually taken out and transferred to a specified position for discharging, the labor cost is high, and since the filter membrane is relatively soft, copper powder is easy to fall off from the filter membrane during the taking-out and transferring process, which is not conducive to the speed increase and efficiency improvement of copper powder production.

[0007] By adopting the technical scheme, when in use, first, the lifting mechanisms of the solid-liquid separation devices lift the upper cylinders in sequence, so that the operator can place the filter membranes in sequence. After the filter membranes are installed, the lifting mechanisms put the lower cylinders back to the lower limit, and the filter membranes are pressed and attached between the upper cylinders and the lower cylinders. After the mixed liquid is injected into the upper cylinders, the vacuum extraction device is started, a negative pressure environment is formed in the lower cylinders, the liquid in the mixed liquid penetrates the filter membranes and enters the lower cylinders, and the copper powder is left above the filter membranes, so that the solid-liquid separation is realized. After the solid-liquid separation is completed, the lifting mechanisms lift the upper cylinders, at the same time, the suction mechanisms suck the filter membranes and synchronously drive the filter membranes to be lifted. When the lifting mechanisms are lifted to the upper limit, the driving mechanisms drive the lifting mechanisms to move towards the conveying mechanism, so that the filter membranes are moved to the positions directly above the corresponding discharge grooves. Then, the lifting mechanisms are lowered, and the filter membranes are placed into the corresponding discharge grooves, so that the placement and taking of the filter membranes are completed.

[0045] In use, first, the lifting mechanism 6 of each solid-liquid separation device 1 lifts the upper cylinder 11 in sequence, so that the operator can place the filter membrane 13 in sequence. 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 and attached between the upper cylinder 11 and the lower cylinder 12; after the mixed solution is injected into the upper cylinder 11, the vacuum pumping device 4 is started, a negative pressure environment is formed in the lower cylinder 12, the liquid in the mixed solution penetrates through the filter membrane 13 and enters the lower cylinder 12, and the copper powder is left above the filter membrane 13, so that solid-liquid separation is realized. After the solid-liquid separation is completed, the lifting mechanism 6 lifts the upper cylinder 11, at the same time, the suction mechanism 5 sucks the filter membrane 13 and synchronously drives the filter membrane 13 to be lifted, when the lifting mechanism 6 is lifted to the upper limit position, the driving mechanism 7 drives the lifting mechanism 6 to move towards the conveying mechanism 3, and the filter membrane 13 is moved to the position directly above the corresponding discharging groove 311. Then, the lifting mechanism 6 is lowered, the filter membrane 13 is placed in the corresponding discharging groove 311, and the taking and placing of the filter membrane 13 are completed. The conveying mechanism 3 can be used to transport the discharging table 31, the position of the discharging groove 311 can be switched when the discharging table 31 rotates, and in this way, a plurality of filter membranes 13 can be collected in sequence.

[0047] With reference to Figures 2-3 and Figure 5 The outer side of the lower end of the upper cylinder 11 is fixed with an upper flange skirt 111, and the outer side of the upper end of the lower cylinder 12 is fixed with a lower flange skirt 121. The top of the lower cylinder 12 is fixed with a supporting net plate 122, and the top surface of the supporting net plate 122 is flush with the top surface of the lower flange skirt 121. The bottom of the upper flange skirt 111 is provided with an annular installation groove 1111, and a sealing ring 1112 is installed in the installation groove 1111. The filter membrane 13 is press-fit between the sealing ring 1112 and the lower flange skirt 121. The filter membrane 13 can be supported by the supporting net plate 122, and the liquid on the upper side of the filter membrane 13 can pass through the filter membrane 13 and enter the lower cylinder 12. The arrangement of the upper sealing skirt, the lower sealing skirt and the sealing ring 1112 ensures the sealing performance of the contact part of the upper cylinder 11, the lower cylinder 12 and the filter membrane 13, which can avoid the leakage of the mixed liquid injected into the upper cylinder 11 and the formation of gaps between the lower cylinder 12 and the filter membrane 13, which is not conducive to the formation of a negative pressure environment.

[0048] With reference to Figure 4 and Figure 6 The outer side of the lower flange skirt 121 is welded with a plurality of lower locking frames 123, which are uniformly arranged on the outer periphery of the lower flange skirt 121. The lower locking frames 123 are provided with locking pins 124, and the locking pins 124 are rotatably connected to the lower locking frames 123 through pin shafts 1241. The outer side of the upper flange skirt 111 is welded with upper locking frames 112 corresponding to the lower locking frames 123. The outer side of the upper locking frames 112 is provided with opening grooves 1121 through which the locking pins 124 pass. The locking pins 124 are threadedly connected with locking nuts 125, and the bottom end of the locking nuts 125 abuts against the top end of the upper locking frames 112. In this way, the upper locking frames 112 and the lower locking frames 123 can be tightened through the locking pins 124 and the locking nuts 125, so as to further ensure the sealing performance between the upper end surface of the filter membrane 13 and the upper cylinder 11 and between the lower end surface of the filter membrane 13 and the lower cylinder 12.

[0049] With reference to Figure 4 and Figure 7The lifting mechanism 6 comprises a moving frame 61 arranged on the truss 2 and a lifting cylinder 62 mounted on the moving frame 61, the moving frame 61 is connected with the driving mechanism 7, and the lifting cylinder 62 is vertically arranged above the upper cylinder 11. An outer edge of an upper end of the upper cylinder 11 is welded with a connecting lug 113, a piston rod of the lifting cylinder 62 is threadedly connected with a fastener 621 after penetrating through the connecting lug 113, a compression spring 622 is sleeved on the piston rod of the lifting cylinder 62, one end of the compression spring 622 is connected with the connecting lug 113, and the other end is connected with a cylinder body of the lifting cylinder 62. In the embodiment, the fastener 621 is a nut. In this way, the lifting cylinder 62 can realize lifting driving of the upper cylinder 11, and the compression spring 622 can buffer the collision between the upper cylinder 11 and the lower cylinder 12 on one hand, and can perform differential compensation on the actual lifting height of the upper cylinder 11 on the other hand, so as to ensure that the upper cylinder 11 is tightly attached to the lower cylinder 12.

[0050] With reference to Figure 4 and Figure 7 , the truss 2 is a double-track truss, both ends of the moving frame 61 are provided with rollers 611, and the inner side of the truss 2 is provided with guide grooves 21 matched with the rollers 611. The driving mechanism 7 comprises an electric push rod 71 fixed to the truss 2, and a moving end of the electric push rod 71 is connected with the moving frame 61. The electric push rod 71 can drive the moving frame 61 to move, thereby achieving the purpose of driving the upper cylinder 11 to move longitudinally. Through the arrangement of the rollers 611 and the guide grooves 21, the friction generated when the moving frame 61 moves can be reduced.

[0051] With reference to Figure 2 and Figure 5 , the filter membrane 13 is attached with a plurality of magnetic conductive blocks 131 having magnetic conductivity, the plurality of magnetic conductive blocks 131 are arranged in a circumferential array on the top surface of the filter membrane 13, and the magnetic conductive blocks 131 are located inside the upper cylinder 11 after the filter membrane 13 is installed. The suction mechanism 5 comprises a plurality of suction assemblies, each of the suction assemblies comprises a suction support 51 corresponding to the magnetic conductive blocks 131 and an electromagnet 52, the suction support 51 is fixed to the inner wall of the upper cylinder 11, and the electromagnet 52 is slidingly arranged on the suction support 51 in the radial direction of the upper cylinder 11. The suction support 51 is further provided with an elastic reset member 511, one end of the elastic reset member 511 is connected with the innermost side of the suction support 51, and the other end is connected with the electromagnet 52.

[0052] The magnetism of the electromagnet 52 can be controlled by power on and off, which is convenient for attracting the filter membrane 13 at a preset time. After the filter membrane 13 is attracted, the filter membrane 13 is lifted with the upper cylinder 11. Since the filter membrane 13 has a certain flexibility, and the elastic return member 511 can be deformed after being pressed, the copper powder on the filter membrane 13 can gradually gather to the center, the middle part of the filter membrane 13 gradually drops, so that the filter membrane 13 forms a shape of low in the middle and high around 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 position directly above the discharge chute 311, the lifting mechanism 6 drives the upper cylinder 11 to descend by a certain height until the filter membrane 13 contacts the wall of the discharge chute 311, then the electromagnet 52 is powered off, the discharge table 31 collects the filter membrane 13, and at the same time, the elastic return member 511 drives the electromagnet 52 to reset to correspond to the position of the magnetism guide block 131 on the filter membrane 13, so as to facilitate the attraction of the next batch of filter membrane 13 after solid-liquid separation.

When cleaning, water is supplied to the upper cylinder 11 through the water inlet pipe 811, and then the stirring assembly 82 stirs the water in the upper cylinder 11, so as to improve the cleaning effect of the upper cylinder 11.

[0054] With reference to Figures 2-3 The stirring assembly 82 includes a stirring motor 821 and a stirring rod 822 coaxially fixed to the output end of the stirring motor 821. The stirring motor 821 is fixed to the upper cylinder 11 through a fixed plate 8211. The rod wall of the stirring rod 822 is fixed with a stirring paddle 8221, and the stirring paddle 8221 is arranged without interfering with the attracting mechanism 5.

After the solid-liquid separation of the mixed liquid is completed, the lower cylinder 12 collects the separated liquid, and the liquid in the lower cylinder 12 can be discharged through the liquid outlet pipe 127 after the liquid outlet valve 1271 is opened. When the solid-liquid separation is performed, the liquid outlet valve 1271 is closed to ensure the air tightness of the lower cylinder 12, which is beneficial to the rapid formation of a negative pressure environment in the lower cylinder 12 after the vacuumizing device 4 works; by setting the bottom of the lower cylinder 12 as dome-shaped, the compression strength of the lower cylinder 12 is improved, and the possibility of inward concave deformation of the lower cylinder 12 is reduced.

[0056] With reference to Figures 9-10 The bottom end of each of the lower discharge grooves 311 is formed with a liquid leakage hole 312 after penetrating the lower discharge table 31, the bottom of the lower discharge table 31 is fixed with a ring-shaped liquid collecting box 32, each of the liquid leakage holes 312 communicates with the inside of the liquid collecting box 32, the side wall of the liquid collecting box 32 is communicated with a liquid discharge pipe 321 at the lower end, and the outer end of the liquid discharge pipe 321 is installed with a plug 322. After the solid-liquid separation of the mixed liquid is completed, 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 is attached to the bottom surface of the filter membrane 13. When the lower discharge table 31 collects the filter membrane 13, the setting of the liquid leakage hole 312 facilitates the liquid collecting box 32 to collect the liquid beads remaining on the bottom surface of the filter membrane 13, and avoids the pollution of the waste liquid to the table surface of the lower discharge table 31.

[0057] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape and principle of the present application should be covered into the protection scope of the present application.
