[0002] At present, the main method for recovering precious metals from copper-containing sludge is through drying and solidification + reduction smelting. During drying and solidification, in order to increase the sludge processing volume, natural drying requires a large area and wastes space.

[0055] Example 3

[0056] like Fig. 9 , Fig.10 As shown, in a specific embodiment, a first slide groove 400 is provided on the side of the side substrate 100, and second slide grooves 401 are provided at both ends of the top of the first slide groove 400, and the second slide groove 401 is arranged in an inclined manner. A blocking rod 403 is fixedly installed on one side of the lower connecting plate 507, and the blocking rod 403 is adapted to the first slide groove 400 and the second slide groove 401, and a baffle 402 is rotatably connected to the bottom of the second slide groove 401. In this configuration, the blocking rod 403 follows the connecting block 504 to slide in the first slide groove 400, and when one of the blocking rods 403 slides to the second slide groove 401, the blocking rod 403 moves upward under the action of the inclined second slide groove 401 and the baffle 402, and drives the lower connecting plate 507 to rise.

[0057] like Figure 8-Figure 11As shown, further, each second slide groove 401 is slidably connected to a card block 404 at the top position, one end of the card block 404 is rotatably connected to a first rotating shaft 405, a slide bar 406 is movably inserted on the first rotating shaft 405, the end of the slide bar 406 is rotatably connected to one side of the side substrate 100, a second rotating shaft 407 is movably sleeved on the slide bar 406, a pressing plate 408 is rotatably connected between the two second rotating shafts 407 located on the same side substrate 100, and a support rod 409 is fixedly installed on one side of the pressing plate 408. 409 movably penetrates the side base frame 101, and a movable groove 410 is opened at the side base frame 101 at the support rod 409.

The outer ends of the support rods 409 on both sides are fixedly installed with side rods 411, and a top plate 412 is fixedly installed between the two side rods 411. The bottom of the top plate 412 is rotatably connected to the top of the stirring shaft 105, and electric push rods 413 are fixedly installed at both ends of the bottom of the top plate 412, and the bottom of the electric push rod 413 is fixedly installed on the top of the drying box 102. In this arrangement, when the top plate 412 rises, it drives the side rod 411 to rise. The side rod 411 drives the pressure plate 408 to rise through the support rod 409. The pressure plate 408 drives the slide bar 406 to rotate through the second rotating shaft 407.

When resetting, the electric push rod 413 contracts and drives the top plate 412 to reset. When the top plate 412 is reset, it drives the pressure plate 408 to reset through the side rod 411 and other components. The pressure plate 408 drives the block 404 to move through the slide bar 406 and disengages from the blocking rod 403.

[0058] like Figure 1 , Figure 2 , Figure 6 , Figure 7 As shown, further, a conveyor belt 603 is installed between the two side base plates 100, a pad 604 is installed on the side base plate 100 located inside the conveyor belt 603, a side connecting plate 600 is fixedly installed at one end of the side base plate 100, a roller 601 is rotatably connected to one side of the side connecting plate 600, the bottom of the roller 601 is in contact with the top of the conveyor belt 603, and a crushing roller 602 is installed between the two rollers 601. In this setting, the dried copper-containing sludge block falls on the conveyor belt 603, and the conveyor belt 603 drives the roller 601 to rotate through friction, thereby rotating the crushing roller 602, and when the sludge block moves to the crushing roller 602, the crushing roller 602 crushes the sludge block, thereby achieving the crushing of the sludge block.

[0059] like Figure 1 As shown, further, two feeding troughs 700 are provided on one side of the side substrate 100. In this configuration, the feeding trough 700 is used to add the copper-containing sludge to be dried.

[0060] The implementation principle of the device for recovering precious metals from copper-containing sludge of this embodiment is as follows: when in use, the two drying tanks 501 are respectively located at different positions, one of which is filled with copper-containing sludge and is located at the bottom of the drying box 102, and the other drying tank 501 is located at the bottom of the feeding trough 700, and the copper-containing sludge is added through the feeding trough 700, and at the same time, the motor 110 rotates to drive the worm 109 to rotate, the worm 109 drives the worm wheel 108 to rotate through meshing, the worm wheel 108 drives the limit plate 107 to rotate, the limit plate 107 drives the stirring shaft 105 to rotate through the limit groove 106, and the stirring shaft 105 drives the stirring wheel 104 to rotate, and stirs the copper-containing sludge to speed up its drying speed;

[0061] When drying is completed, the electric push rod 413 is started, and the electric push rod 413 drives the top plate 412 to rise, so that the stirring shaft 105 drives the stirring wheel 104 to rise and separate from the drying tank 501. The top plate 412 rises and drives the side rod 411 to rise. The side rod 411 drives the pressure plate 408 to rise through the support rod 409. The pressure plate 408 drives the sliding rod 406 to rotate through the second rotating shaft 407. The sliding rod 406 drives the block 404 to move through the first rotating shaft 405, so that the block 404 abuts against one end of the second slide groove 401.

[0062] At this time, the driving device 301 is started, and the driving device 301 drives the gear 302 to rotate. The gear 302 drives the first mounting frame 300 and the second mounting frame 304 to move by meshing with the tooth groove 303. The second mounting frame 304 drives the support plate 500 to move, so that the two drying tanks 501 move. At the same time, the second mounting frame 304 drives the connecting block 504 and its connecting components to move. At this time, the blocking rod 403 follows the connecting block 504 to slide in the first sliding groove 400. When one of the blocking rods 403 slides to the second sliding groove 401, the blocking rod 403 is in the second sliding groove 401 that is inclined. The groove 401 and the baffle plate 402 move upward, and drive the lower connecting plate 507 to rise. The lower connecting plate 507 drives the V-shaped groove 505 to rise through the first sliding shaft 506. The V-shaped groove 505 drives the swing rod 502 to rotate by abutting against the limit column 503, so as to realize the flipping of the drying groove 501, until the baffle 403 moves to the block 404. At this time, the block 404 abuts against the baffle 403. At this time, the dried copper-containing sludge in the drying groove 501 falls on the conveyor belt 603, and the drying groove 501 on the other side filled with the copper-containing sludge to be dried moves to the drying box 102 for drying;

[0063] The worm gear 108 drives the limit plate 107 to rotate, and drives the cam 200 to rotate. The flange of the cam 200 abuts against the push plate 203, and the push plate 203 abuts against the connecting frame 205, so that it rotates. The connecting frame 205 drives the connecting rod 208 to move downward. When the flange of the cam 200 is staggered from the push plate 203, the tension of the tension spring 207 pulls the fixing frame 206 to reset, so that the connecting frame 205 is reset. The connecting frame 205 drives the connecting rod 208 to reset through the supporting plate 209. In this way, the connecting frame 205 knocks on the turned drying tank 501, thereby vibrating and removing the sludge blocks remaining in the drying tank 501.

[0064] After the cleaning is completed, the electric push rod 413 is reset, and the electric push rod 413 contracts to drive the top plate 412 to reset, so that the top plate 412 descends, and the top plate 412 drives the stirring shaft 105 and the stirring wheel 104 to descend, and the copper-containing sludge is stirred. When the top plate 412 is reset, the pressure plate 408 is reset through the side rod 411 and other components, and the pressure plate 408 drives the block 404 to move through the slide bar 406 and disengages from the stop rod 403. At this time, the spring 509 pushes the lower connecting plate 507 to move downward, and the lower connecting plate 507 drives the first sliding shaft 506 to move downward, and the first sliding shaft 506 drives the V-shaped groove 505 to move downward. The V-shaped groove 505 drives the drying tank 501 to rotate and reset through the limit column 503 and the swing rod 502. At this time, the copper-containing sludge can be added to the drying tank 501 through the feeding trough 700.

[0065] Repeating the above steps can realize the cyclic operation of stirring, drying, unloading, cleaning and loading of the copper-containing sludge;

[0066] The dried copper-containing sludge block falls on the conveyor belt 603, and the conveyor belt 603 drives the roller 601 to rotate through friction, thereby rotating the crushing roller 602. When the sludge block moves to the crushing roller 602, the crushing roller 602 crushes the sludge block, thereby achieving the crushing of the sludge block.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
