There is a filter cloth 18, and a plurality of through holes 16 are provided on the side of the pressure plate 7 close to the filter cloth 18. A cavity 17 is provided in the pressure plate 7. A liquid outlet pipe 14 is fixedly connected to one side of the cavity 17. The liquid outlet pipe 14 passes through one side wall of the pressure plate 7. A second cylinder 10 is fixedly connected to one side of the recovery tank 5. A push block 11 is fixedly connected to the output end of the second cylinder 10. The push block 11 is slidingly connected to the recovery tank 5. A plurality of connecting pipes 20 are fixedly connected to one side of the recovery tank 5. The liquid outlet pipe 14 is fixedly connected to a connecting pipe 20. A discharge structure is provided in the recovery tank 5. The discharge structure includes a discharge port 3 provided at the bottom of the recovery tank 5. The discharge structure is used to discharge the separated solids in the recovery tank 5 out of the recovery tank 5 through the discharge port 3 and recycle them.

[0034] Specifically, when recovering gold, silver and platinum noble metals from antimony smelting waste residues, the waste residues generated after antimony smelting are crushed and then poured into aqua regia solution. After the reaction, the waste residues that cannot be dissolved are filtered out. The solution contains gold, silver and platinum noble metals. Different reducing agents are then added to reduce gold, silver and platinum into solids, respectively. The gold, silver and platinum solids are separated from the solution by pouring and filtering the solution and allowing the solids to settle. The gold, silver and platinum solids can be recovered and smelted for purification. This process is complex and the filtration is not sufficient, resulting in low recovery efficiency of gold, silver and platinum noble metals and increasing the time required for recovery of gold, silver and platinum noble metals.

[0035] In the process of recovering gold, silver and platinum noble metals, the waste residues after antimony smelting are first ground into powder in the grinding machine 1. The ground waste residues are then placed in the recovery tank 5. Aqua regia solution is added to the recovery tank 5 through the connecting pipe 20 to dissolve the waste residues. After a period of reaction and dissolution, the first cylinder 6 is started to move the pressing plate 7 downward. The pressing plate 7 drives the sliding plate 9 to move downward into the recovery tank 5 and press the solution in the recovery tank 5. At the same time, the second cylinder 10 is started to move the push block 11 away from the second cylinder 10 to press the sliding plate 9. The sliding plate 9 is moved to the pressing plate 7 through the support rod 12 and compresses the first spring 13. The push block 11, together with the pressing plate 7 and the sliding plate 9, can press the solution in the recovery tank 5. The solution can pass through the filter cloth 18 and the through hole 16 into the cavity 17 and flow out from the outlet pipe 14. The solid separated from the solution is further compressed by the discharging structure to separate the solution from the solid. The separated solid is discharged from the recovery tank 5 through the discharge port 3 for smelting. After the solid in the recovery tank 5 is completely discharged, the first cylinder 6 and the second cylinder 10 drive the pressing plate 7 and the push block 11 back to the initial position. The solution discharged from the outlet pipe 14 is injected into the recovery tank 5 again through the connecting pipe 20. The reducing agent is added to the recovery tank 5 through the connecting pipe 20 to reduce gold, silver and platinum into solids. The process is repeated to separate and recover gold, silver and platinum noble metals from the waste residues, reducing the steps of recovering gold, silver and platinum noble metals, and improving the separation of the solution from gold, silver and platinum noble metals, thereby improving the efficiency of recovering gold, silver and platinum noble metals from the waste residues.

[0037] Specifically, the filtered solution can flow into the recovery tank 5 from the outside of the recovery tank 5 through the connecting pipes 20.

[0040] As shown in Figure 4 The two sides of the sliding plate 9 are fixed with sliding blocks 22, the two sides of the pressing plate 7 are provided with sliding grooves 21, the two sliding blocks 22 are slidably connected with the sliding grooves 21, and the sliding plate 9 located on one side of the two first springs 13 is provided with an annular groove 15, and the two first springs 13 are slidably connected with the annular groove 15.

[0041] Specifically, the sliding of the sliding plate 9 in the pressing plate 7 is limited by the sliding of the sliding blocks 22 in the sliding grooves 21, when the sliding plate 9 is completely slid into the pressing plate 7, the first spring 13 is completely compressed and slides into the annular groove 15 to save the sliding space in the pressing plate 7.

[0042] As shown in Figure 7 The discharge structure further comprises a first threaded rod 30 rotatably connected to one side of the recovery tank 5, a second motor 29 fixed to one side of the recovery tank 5 and fixed to the output end of the first threaded rod 30, and a push plate 31 slidably connected in the recovery tank 5 and threadedly connected with the first threaded rod 30.

[0043] Specifically, when the reduced gold, silver and platinum solids are recovered and discharged from the recovery tank 5, the second motor 29 is started to drive the first threaded rod 30 to rotate and further drive the push plate 31 to slide in the recovery tank 5, so as to further filter and separate the solution in the reduced gold, silver and platinum solids.

[0044] As shown in Figure 8As shown, the discharging structure further comprises a third motor 35 fixed on one side of the push plate 31, the one side of the push plate 31 is fixed with a protective shell 32, the output end of the third motor 35 penetrates through the protective shell 32 and is fixed with the second gear 34, the one side of the push plate 31 is rotatably connected with the first gear 33 in the protective shell 32, the first gear 33 is in meshing connection with the second gear 34, the one side of the push plate 31 is rotatably connected with a brush roller 36, one end of the brush roller 36 penetrates through the protective shell 32 and is fixed with the first gear 33, and the push plate 31 is fixed with a shovel 37 on both sides of the brush roller 36.

[0046] As shown in Figure 9 The discharging structure further comprises a fourth motor 38 fixed on one side of the first threaded rod 30 in the recovery tank 5, the output end of the fourth motor 38 is fixed with a second threaded rod 40, the second threaded rod 40 is rotatably connected with the recovery tank 5, a scraper 41 is slidably connected in the recovery tank 5, and the scraper 41 is in threaded connection with the second threaded rod 40.

[0047] Specifically, when the reduced gold, silver and platinum solids are recovered and discharged from the recovery tank 5, the fourth motor 38 is started to rotate the second threaded rod 40, the second threaded rod 40 drives the scraper 41 to slide in the recovery tank 5 to separate the further compressed and separated noble metal solids and push them out of the recovery tank 5 through the discharge port 3, so that the separated noble metal solids are more convenient for collection and smelting and purification.

[0048] As shown in Figure 7 The two sides of the scraper 41 are fixed with barrier plates 39, and the two barrier plates 39 are slidably connected with the recovery tank 5.

[0049] Specifically, when the noble metal solids are discharged from the recovery tank 5 by the scraper 41, the two barrier plates 39 can prevent the noble metal solids from entering the inner wall of the recovery tank 5 when the scraper 41 moves, so as to prevent the noble metal solids from being left over in the recovery and affecting the rotation of the second threaded rod 40 and the movement of the scraper 41. Example two

[0050] As shown in Figures 9 and 10 Comparative example one, wherein another embodiment of the present application is:

[0051] The discharging structure also includes a discharging door 42 that is slidably connected to the recovery pool 5 on one side of the discharging port 3. A fixed rod 43 is fixed to one side of the discharging door 42 in the recovery pool 5. The fixed rod 43 is slidably connected to the discharging door 42. A second spring 44 is sleeved on the fixed rod 43. One end of the second spring 44 is fixed to the recovery pool 5, and the other end of the second spring 44 is fixed to the discharging door 42.

[0052] Specifically, when the precious metal solids are discharged through the discharge port 3 , the discharge door 42 slides in the recovery tank 5 via the fixed rod 43 and the second spring 44 to open and close the discharge port 3 to control the reaction or discharge of the precious metal solids.

[0053] like Figure 9 As shown, one end of the discharge door 42 is rotatably connected to one end of the clamping plate 46, and the other end of the clamping plate 46 is set as an inclined protrusion. One side of the discharge door 42 is fixedly connected to one end of the third spring 45, and the other end of the third spring 45 is fixedly connected to the clamping plate 46. A clamping groove matching the clamping plate 46 is opened on one side of the discharge port 3.

[0054] Specifically, when opening the discharge port 3, the third spring 45 is compressed by pressing the card plate 46 and rotating it, and the card plate 46 is moved toward the direction of the fixed rod 43 to be stuck in the card slot. The card plate 46 drives the discharge door 42 to move and clamp the fixed discharge door 42 to open the discharge port 3 and discharge the precious metal solids.

[0055] Working principle: When recycling precious metals such as gold, silver, and platinum, first put the waste residue after smelting antimony into the grinding machine 1 and grind it into powder. Then put the ground waste residue into the recovery tank 5. Then add the aqueous regia solution into the recovery tank 5 through the connecting pipe 20 to dissolve the waste residue. After a period of reaction and dissolution, start the first cylinder 6 to move the pressure plate 7 downward. The pressure plate 7 drives the slide plate 9 to move downward into the recovery tank 5 and squeeze the solution in the recovery tank 5. At the same time, start the second cylinder 10 to move the push block 11 away from the second cylinder 10 to press the slide plate 9, so that the slide plate 9 moves to the pressure plate 7 through the support rod 12. By compressing the first spring 13, the solution in the recovery pool 5 can be squeezed together by the push block 11 with the pressure plate 7 and the slide plate 9, so that the solution passes through the filter cloth 18 and the through hole 16 faster and enters the cavity 17 and flows out from the liquid outlet pipe 14. The solid separated from the solution is further compressed by the discharging structure to squeeze the solution out and separate it from the solid, and the separated solid is discharged from the recovery pool 5 through the discharge port 3 for collection and smelting. After the solid in the recovery pool 5 is completely discharged, the first cylinder 6 and the second cylinder 10 respectively drive the pressure plate 7 and the push block 11 to return to the initial position, and then the solid is discharged from the recovery pool 5 through the discharge port 3. The connecting pipe 20 injects the solution discharged from the liquid outlet pipe 14 into the recovery tank 5 again, and the reducing agent is put into the recovery tank 5 through the connecting pipe 20 to reduce the gold, silver and platinum into solids respectively, and the above process is repeated to gradually separate the gold, silver and platinum precious metals in the waste residue from the solution and recover them; the filtered solution can be pushed through the one-way valve 19 from the outside of the recovery tank 5 through the connecting pipe 20 to flow into the recovery tank 5, and the one-way valve 19 will close the inlet of the connecting pipe 20 so that the solution in the recovery tank 5 will not flow out of the connecting pipe 20; when the waste residue is dissolved, the first motor 23 is started to rotate the rod 24 The limit block 27 rotates with it, and the limit block 27 slides in the limit groove 28, causing the fan blade block 26 to first slide upward in the rotating disk 25 and then rotate with the rotating rod 24. The fan blade block 26 rotates with the rotating disk 25 to stir the solution in the recovery tank 5, thereby accelerating the dissolution of waste residue and the reduction process of precious metals such as gold, silver, and platinum from the solution; the sliding of the slide plate 9 in the pressure plate 7 is limited by the sliding of the slider 22 in the slide groove 21. When the slide plate 9 slides completely into the pressure plate 7, the first spring 13 is fully compressed and slides into the annular groove 15 to save sliding space in the pressure plate 7.

[0056] When the reduced gold, silver and platinum solids are recovered and discharged from the recovery pool 5, the second motor 29 is started to rotate the first threaded rod 30 and then the push plate 31 is caused to slide in the recovery pool 5, further filtering and separating the solution in the reduced gold, silver and platinum solids; when the push plate 31 moves to further filter and separate the solution in the reduced gold, silver and platinum solids, the third motor 35 is started to rotate the second gear 34, and the second gear 34 drives the first gear 33 to rotate, thereby rotating the brush roller 36 to clean and recover the residual precious metal solids on the surface of the filter cloth 18, and then the cleaned precious metal solids are collected by the shovel block 37 and discharged from the recovery pool 5; when the precious metal solids are discharged from the recovery pool 5 by the scraper 41, the fourth motor 38 is started to rotate the second threaded rod 40, and the second threaded rod 40 drives the scraper 41 to slide in the recovery pool 5 to further compress and separate the precious metal solids and pass The precious metal solids are pushed out of the recovery pool 5 through the discharge port 3, and the separated precious metal solids are easier to collect, smelt and purify; when the precious metal solids are discharged from the recovery pool 5 through the scraper 41, the two blocking plates 39 can prevent the precious metal solids from entering the inner wall of the recovery pool 5 when the scraper 41 moves, thereby preventing the precious metal solids from being residual and affecting the rotation of the second threaded rod 40 and the movement of the scraper 41; when the precious metal solids are discharged through the discharge port 3, the discharge door 42 slides in the recovery pool 5 through the fixed rod 43 and the second spring 44 to open and close the discharge port 3 to control the reaction or discharge of the precious metal solids; when opening the discharge port 3, the third spring 45 is compressed by pressing the card plate 46, and the card plate 46 is moved in the direction of the fixed rod 43 to be stuck in the card slot, and the card plate 46 drives the discharge door 42 to move and clamps the fixed discharge door 42 to open the discharge port 3 to discharge the precious metal solids.
