Description

Technical Field

[0001] This utility model relates to the field of silver recovery technology, and in particular to a drying device for recovering silver from silver-plated copper alloys. Background Technology

[0002] Silver is a rare and precious metal. Recovering silver from silver-plated copper alloys can effectively save on the mining of primary silver mines and alleviate resource pressure. Recovering silver from silver-plated copper alloys is a common silver recycling method.

[0003] During the recovery process, in the chemical precipitation stage, after adding sodium chloride to precipitate silver ions into silver chloride, the filter cake needs to be washed and dried to remove moisture and residual impurities, facilitating the subsequent reduction reaction. Because the filter cake has a high density, the internal moisture is difficult to dry, resulting in lower drying efficiency. Furthermore, the dried filter cake is not in a dispersed state, which is detrimental to subsequent steps. Utility Model Content

[0004] This utility model discloses a drying device for recovering silver from silver-plated copper alloy, which aims to solve the technical problems that the high density of the filter cake makes it difficult to dry the internal moisture, resulting in poor drying efficiency, and the fact that the dried filter cake is not in a dispersed state, which is not conducive to subsequent steps.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drying device for recovering silver from a silver-plated copper alloy includes a drying chamber, an electric heater fixedly connected to one inner wall of the drying chamber, a triangular filter cloth movably connected to the inner wall of the top of the drying chamber, a water absorption mechanism movably connected to the inner walls of opposite sides of the drying chamber, a pressing mechanism fixedly connected to the top of the drying chamber, and a squeezing mechanism fixedly connected to the outer walls of opposite sides of the drying chamber.

[0007] The water absorption mechanism includes multiple layers of polyester fiber cloth and a filter screen fixedly connected to the middle of each layer of polyester fiber cloth, with the multiple layers of polyester fiber cloth stacked at the bottom of the triangular filter cloth.

[0008] The extrusion mechanism includes two symmetrically arranged electric telescopic rods and an extrusion plate fixedly connected to the output end of each electric telescopic rod.

[0009] The top inner wall of the drying chamber is provided with a slot, and the top outer wall of the drying chamber is connected to a sealing door by a hinge. The top of the triangular filter cloth is fixedly connected to a support edge, and the support edge is movably engaged in the slot. The sealing door fits and covers the top of the support edge.

[0010] Mounting plates are fixedly connected to the outer walls of the opposite sides of the drying chamber, and each electric telescopic rod is fixedly connected to the mounting plate. Grooves are provided on the inner walls of the opposite sides of the drying chamber, and two extrusion plates are movably connected to the grooves.

[0011] Equipped with a water absorption mechanism and a pressing mechanism, the residual washing liquid in the filter cake drips down the triangular prism filter cloth and multiple filter screens to the bottom of the drying chamber. Then, it is squeezed from both sides of the triangular prism filter cloth by the extrusion plates on both sides. At this time, the multi-layer polyester fiber cloth is located between the extrusion plates and the triangular prism filter cloth. Through extrusion, the residual moisture in the filter cake can be quickly absorbed by the multi-layer polyester fiber cloth. After the polyester fiber cloth is separated from the triangular prism filter cloth, it continues to be squeezed and dried by the extrusion plates. With this structure, the drying time can be reduced to a large extent, and the filter cake can also be dispersed, which facilitates the next processing step.

[0012] In a preferred embodiment, the water absorption mechanism further includes multiple sets of sliding rods, multiple sets of cross-type connecting rods, deep waist-shaped grooves and shallow waist-shaped grooves, each set of sliding rods includes two symmetrically arranged sliding rods, and each polyester fiber cloth is fixedly connected to each set of sliding rods;

[0013] The deep waist-shaped groove is fixedly connected to the top of the shallow waist-shaped groove. The uppermost sliding rod is the longest and is movably connected inside the deep waist-shaped groove. The other sliding rods are of the same length.

[0014] The remaining sliding rods of the same length are simultaneously movably connected in the shallow waist-shaped groove, and multiple sets of the cross-shaped connecting rods are simultaneously movably sleeved at both ends of the sliding rods located on the same side;

[0015] Each of the slide rods has multiple limiting brackets fixedly connected to its outer circumference, and each limiting bracket is movably attached to the outer wall of the cross-type linkage assembly.

[0016] By incorporating a water-absorbing mechanism, multiple sets of sliding rods are connected by multiple sets of cross-link groups. This limits the maximum distance between adjacent sets of sliding rods. In addition, the lowest point of the uppermost sliding rod is controlled, and the other sliding rods are equidistantly separated under the constraint of the cross-link groups. This increases the distance between each polyester fiber cloth, making it easier to dry and reuse.

[0017] In a preferred embodiment, the pressing mechanism includes an electric multi-section telescopic rod, an electromagnetic block and an iron plate fixedly connected to the output end of the electric multi-section telescopic rod;

[0018] The two bottommost sliding rods are simultaneously connected to crossbars on both sides, and a pressing plate is fixedly connected to one side of the outer wall of one of the two sliding rods.

[0019] The iron sheet is fixedly connected to the top outer wall of the pressing plate, the electromagnetic block is attracted to the iron sheet, and the electric multi-section telescopic rod is fixedly connected to the top outer wall of the drying chamber, with the output end of the electric multi-section telescopic rod passing through the top of the drying chamber.

[0020] By incorporating a pressing mechanism and an electromagnetic block, the electromagnetic block can be released from its attraction to the iron sheet after power is cut off, thus preventing obstruction of the pressing process of the pressing mechanism.

[0021] As described above, a drying device for recovering silver from silver-plated copper alloy includes a drying chamber, an electric heater fixedly connected to one inner wall of the drying chamber, a triangular filter cloth movably connected to the inner wall of the top of the drying chamber, a water absorption mechanism movably connected to the inner walls of opposite sides of the drying chamber, a pressing mechanism fixedly connected to the top of the drying chamber, and a squeezing mechanism fixedly connected to the outer walls of opposite sides of the drying chamber. The water absorption mechanism includes multiple layers of polyester fiber cloth and a filter screen fixedly connected to the middle of each layer of polyester fiber cloth, with the multiple layers of polyester fiber cloth stacked at the bottom of the triangular filter cloth. The squeezing mechanism includes two symmetrically arranged electric telescopic rods and a squeezing plate fixedly connected to the output end of each electric telescopic rod. The drying device for recovering silver from silver-plated copper alloy provided by this utility model has the technical effect of greatly reducing drying time and also achieving filter cake dispersion, facilitating the next processing step.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] The present invention discloses a drying device for recovering silver from silver-plated copper alloy, which is mainly used in the scenario of silver recovery and drying.

[0029] Reference Figures 1-3 A drying device for recovering silver from a silver-plated copper alloy includes a drying chamber 1, an electric heater 5 fixedly connected to one inner wall of the drying chamber 1, a triangular filter screen 9 movably connected to the inner wall of the top of the drying chamber 1, a water absorption mechanism 6 movably connected to the inner walls of opposite sides of the drying chamber 1, a pressing mechanism 3 fixedly connected to the top of the drying chamber 1, and a squeezing mechanism 4 fixedly connected to the outer walls of opposite sides of the drying chamber 1.

[0030] The water absorption mechanism 6 includes multiple layers of polyester fiber cloth 604 and a filter screen 605 fixedly connected to the middle position of each layer of polyester fiber cloth 604. The multiple layers of polyester fiber cloth 604 are stacked at the bottom of the triangular filter screen 9.

[0031] The extrusion mechanism 4 includes two symmetrically arranged electric telescopic rods 401 and an extrusion plate 403 fixedly connected to the output end of each electric telescopic rod 401. When drying the washed filter cake, the filter cake can be poured into the triangular prism filter screen 9. The residual washing liquid in the filter cake will drip down the triangular prism filter screen 9 and multiple filter screens 605 to the bottom of the drying chamber 1. Then, the electric telescopic rods 401 on both sides will simultaneously drive the two extrusion plates 403 to extrude the triangular prism filter screen 9 from both sides. At this time, the multilayer polyester fiber cloth 604 is located between the extrusion plate 403 and the triangular prism filter screen 9. Through extrusion, the residual moisture in the filter cake can be quickly absorbed by the multilayer polyester fiber cloth 604. Then, the pressing mechanism 3 will make the polyester fiber cloth 604 separate from the triangular prism filter screen 9. The filter cake will then be dried by high temperature. During the drying process, the extrusion plate 403 will continuously extrude the triangular prism filter screen 9. Under this structure, the drying time can be reduced to a large extent, and the filter cake can also be dispersed, which will facilitate the next processing step.

[0032] Reference Figures 1-3 In a preferred embodiment, the top inner wall of the drying chamber 1 is provided with a slot 7, and the top outer wall of the drying chamber 1 is connected to a sealing door 2 by a hinge. The top of the triangular filter screen 9 is fixedly connected to a support edge 8, and the support edge 8 is movably engaged in the slot 7. The sealing door 2 fits and covers the top of the support edge 8.

[0033] Reference Figure 2 In a preferred embodiment, mounting plates 402 are fixedly connected to the outer walls of opposite sides of the drying chamber 1, and each electric telescopic rod 401 is fixedly connected to the mounting plate 402. Grooves 404 are provided on the inner walls of opposite sides of the drying chamber 1, and two extrusion plates 403 are movably connected to the grooves 404.

[0034] Reference Figure 4 In a preferred embodiment, the water absorption mechanism 6 further includes multiple sets of sliding rods 603, multiple sets of cross-type connecting rods 607, deep waist-shaped grooves 601 and shallow waist-shaped grooves 602. Each set of sliding rods 603 includes two symmetrically arranged sliding rods 603, and each polyester fiber cloth 604 is fixedly connected to each set of sliding rods 603.

[0035] Reference Figure 4 In a preferred embodiment, the deep waist-shaped groove 601 is fixedly connected to the top of the shallow waist-shaped groove 602, the uppermost slide rod 603 is the longest and is movably connected in the deep waist-shaped groove 601, and the other slide rods 603 are of the same length.

[0036] Reference Figure 4In a preferred embodiment, the remaining slide rods 603 of the same length are simultaneously movably connected within the shallow waist-shaped groove 602, and multiple sets of cross-shaped connecting rods 607 are simultaneously movably sleeved at both ends of the slide rods 603 located on the same side.

[0037] Reference Figure 4 In a preferred embodiment, each slide rod 603 is fixedly connected to a plurality of limiting frames 606 on its outer circumference, and each limiting frame 606 is movably attached to the outer wall of the cross-type linkage group 607. The multiple sets of slide rods 603 are connected by the multiple sets of cross-type linkage groups 607, thereby limiting the maximum distance between two adjacent sets of slide rods 603. In addition, the lowest point of the uppermost slide rod 603 is controlled as it moves within the deep waist groove 602. As the pressing mechanism 3 moves the multiple polyester fiber cloths 604 down to the uppermost slide rod 603 for positioning, the other slide rods 603 are equidistantly separated under the restriction of the cross-type linkage group 607, thus widening the distance between each polyester fiber cloth 604 and facilitating its drying and reuse.

[0038] Reference Figure 4 In a preferred embodiment, the pressing mechanism 3 includes an electric multi-section telescopic rod 301, an electromagnetic block 302 and an iron sheet 304 fixedly connected to the output end of the electric multi-section telescopic rod 301.

[0039] Reference Figure 4 In a preferred embodiment, the two bottommost sliding rods 603 are simultaneously fixedly connected to crossbars 608 on both sides, and one of the two sliding rods 603 is fixedly connected to a pressing plate 303 on one side of its outer wall.

[0040] Reference Figure 4 In a preferred embodiment, the iron sheet 304 is fixedly connected to the top outer wall of the pressing plate 303, the electromagnetic block 302 is attracted to the iron sheet 304, and the electric multi-section telescopic rod 301 is fixedly connected to the top outer wall of the drying chamber 1. The output end of the electric multi-section telescopic rod 301 passes through the top of the drying chamber 1. The pressing mechanism 3 mainly drives the bottom slide rod 603 to move up and down by the extension and retraction of the electric multi-section telescopic rod 301 set above. The setting of the crossbar 608 can ensure that the two bottom slide rods 603 move synchronously. Based on the setting of the electromagnetic block 302, the attraction between the electromagnetic block 302 and the iron sheet 304 can be released after the power is cut off, thereby avoiding obstruction of the pressing process of the pressing mechanism 4.

[0041] Working principle: When drying the washed filter cake, the filter cake can be poured into the triangular prism filter screen 9. The residual washing liquid in the filter cake will drip down the triangular prism filter screen 9 and multiple filter screens 605 to the bottom of the drying chamber 1. Then, the electric telescopic rods 401 on both sides drive the two extrusion plates 403 to extrude the triangular prism filter screen 9 from both sides. At this time, the multi-layer polyester fiber cloth 604 is located between the extrusion plates 403 and the triangular prism filter screen 9. Through extrusion, the residual moisture in the filter cake can be quickly absorbed by the multi-layer polyester fiber cloth 604. Then, the pressing mechanism 3 makes the polyester fiber cloth 604 separate from the triangular prism filter screen 9. The filter cake is then dried by high temperature. During the drying process, the extrusion plates 403 continuously extrude the triangular prism filter screen 9. Under this structure, the drying time can be reduced to a large extent, and the filter cake can also be dispersed, which facilitates the next processing step.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions.
