Description

Technical Field

[0001] This utility model relates to the field of solid waste treatment technology, and in particular to a device for recycling gold slag from solid waste. Background Technology

[0002] Gold, as an important precious metal, is widely used in industrial production, and its production and use generate solid waste containing trace amounts of gold. To maximize resource utilization and protect the environment, recycling this gold waste has significant economic and social value. Currently, hydrometallurgical processes are commonly used to treat this waste, which typically include key steps such as grinding and pulverizing the waste, chemical leaching, displacement reactions, and final solid-liquid separation.

[0003] In existing recycling practices, the above-mentioned process steps often rely on a combination of multiple independent pieces of equipment. For example, a separate grinder is used to crush the material, then the powder is transferred to a reaction vessel for leaching, and after the reaction is completed, the mixture is sent to a separation device such as a filter press for solid-liquid separation. This split, multi-stage operation mode has significant drawbacks.

[0004] Because the functional units are separate, materials need to be transferred multiple times between different devices. Transferring the finely ground powder easily generates dust, polluting the workshop environment, posing a threat to the health of operators, and resulting in the loss of gold-containing materials. Simultaneously, when adding chemicals or conveying materials into open or semi-open reactors, irritating or harmful gases from leaching agents and other chemicals can easily volatilize and leak, posing safety hazards. The entire process becomes cumbersome and complex due to multiple transfers, with low automation, significantly reducing overall production and recycling efficiency.

[0005] Therefore, this utility model proposes a solid waste gold slag recycling device to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a solid waste gold slag recycling device, which aims to improve the existing technology where the material transfer process of gold slag recycling devices is complicated and dust and harmful gas leakage are easy to occur during the transfer and feeding process.

[0008] The sealing mechanism includes a feeding port, a flip cover, a first fixed seat, and a limiting rod. The sealing mechanism is installed on the constant temperature tank. The flip cover is used to open and close the feeding port. One end of the limiting rod is connected to the flip cover, and the other end is slidably installed in the first fixed seat to limit the flip angle of the flip cover.

[0009] The sealing mechanism also includes a second fixed seat, a rotating shaft, and a first handle. The first fixed seat and the second fixed seat are fixed to the main body of the device by nuts. The flip cover is rotatably connected around the rotating shaft, and the first handle is disposed on the flip cover.

[0010] Preferably, the pull-out mechanism includes a filter box, a guide rail, and a slide rail. The pull-out mechanism is located at the discharge port of the constant temperature tank, and the filter box is slidably connected to the guide rail and the slide rail.

[0011] Preferably, the pull-out mechanism further includes a second handle, which is connected to the filter box and is used to pull the filter box out.

[0012] Preferably, it also includes a liquid inlet pipe connected to the thermostatic tank and a second valve disposed between the thermostatic tank and the pull-out mechanism.

[0013] Preferably, the device also includes a stirring paddle and a second motor. The stirring paddle is disposed inside the thermostatic tank, and the power output end of the second motor is connected to the stirring paddle to drive the stirring paddle to rotate.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-4This utility model provides a solid waste gold slag recycling device, which aims to solve the problems of large footprint, complex operation, and dust and gas leakage risks caused by the separation of functional units in existing gold slag recycling equipment.

[0027] The device includes a constant temperature tank 11 and a grinding chamber 1 fixed above the constant temperature tank 11 by a bracket 8. The constant temperature tank 11 is used for constant temperature leaching reaction of materials, and the grinding chamber 1 is used for grinding and crushing lumpy waste residue. The grinding chamber 1 is provided with a feed inlet 5. The grinding chamber 1 is connected to the constant temperature tank 11 through a transmission pipe 6 equipped with a first valve 7. The first valve 7 is used to control the entry of the ground powder material into the constant temperature tank 11. The device also includes a first motor 2, a pulley 3, and a synchronous belt 4. The first motor 2 drives the pulley 3, and the pulley 3 drives the grinding component in the grinding chamber 1 to rotate through the synchronous belt 4. The device also includes a stirring paddle 17 and a second motor 12. The stirring paddle 17 is located inside the constant temperature tank 11. The power output end of the second motor 12 is connected to the stirring paddle 17 to drive the stirring paddle 17 to rotate. A liquid inlet pipe 13 is connected to the constant temperature tank 11 for adding liquid into the constant temperature tank 11.

[0028] It also includes a sealing mechanism 9 and a pull-out mechanism 10. The sealing mechanism 9 is installed on the constant temperature tank 11 and is used to prevent dust from overflowing and gas from evaporating when feeding materials into the constant temperature tank 11. The sealing mechanism 9 includes a feeding port 901 and a flip cover 902 for opening and closing the feeding port 901. The sealing mechanism 9 also includes a first fixed seat 904, a second fixed seat 905, a rotating shaft 907 and a limiting rod 906. The first fixed seat 904 and the second fixed seat 905 are fixed to the main body of the device by a nut 908. The flip cover 902 is rotatably connected around the rotating shaft 907. The flip cover 902 is provided with a first handle 903 for easy operation. One end of the limiting rod 906 is connected to the flip cover 902, and the other end is slidably set in the first fixed seat 904. The flip angle of the flip cover 902 is precisely limited by the sliding of the limiting rod 906 in the first fixed seat 904.

[0029] Meanwhile, the pull-out mechanism 10 is located at the discharge port of the constant temperature tank 11, and the connection between the constant temperature tank 11 and the pull-out mechanism 10 is controlled by the second valve 14. The pull-out mechanism 10 is used to efficiently separate the solid and liquid materials after the reaction. The pull-out mechanism 10 includes a filter box 1001, a guide rail 1003, a slide rail 1002, and a second handle 1004. The filter box 1001 is slidably connected through the guide rail 1003 and the slide rail 1002. The second handle 1004 is connected to the filter box 1001 and is used to drive the filter box 1001 to be pulled out smoothly, ensuring the convenience and stability of the filter box 1001 in the picking and putting process. A liquid collection box 16 is also provided below the pull-out mechanism 10 to collect the liquid filtered by the filter box 1001. A drain pipe 15 for discharging waste liquid is connected to the liquid collection box 16.

[0030] To achieve control and sealing of the feeding process, the sealing mechanism 9 includes a first fixed seat 904 and a second fixed seat 905. The first fixed seat 904 and the second fixed seat 905 are fixed to the main body of the device by a nut 908. The flip cover 902 is rotatably connected between the first fixed seat 904 and the second fixed seat 905 by a rotating shaft 907. A first handle 903 for easy operation is also fixedly connected to the flip cover 902. In addition, the sealing mechanism 9 also includes a limiting rod 906. One end of the limiting rod 906 is connected to the flip cover 902, and the other end is slidably disposed in the first fixed seat 904 to limit the opening angle of the flip cover 902 and prevent the opening angle from being too large or too small.

[0031] To facilitate the removal of solid materials after solid-liquid separation and the maintenance of the filter screen, the pull-out mechanism 10 includes a guide rail 1003 and a slide rail 1002. The guide rail 1003 and the slide rail 1002 are fixedly installed below the discharge port of the constant temperature tank 11. The filter screen box 1001 is pulled out by sliding cooperation with the guide rail 1003 and the slide rail 1002. A second handle 1004 is also fixedly connected to the filter screen box 1001 to facilitate the pull-out operation of the filter screen box 1001.

[0032] In order to control the reaction process inside the constant temperature tank 11, a liquid inlet pipe 13 connected to the constant temperature tank 11 is also included for conveying liquids such as leaching agents into the tank. A second valve 14 is also provided between the discharge port of the constant temperature tank 11 and the pull-out mechanism 10 for controlling the discharge of materials after the reaction is completed.

[0033] In order to make the waste residue powder and leaching agent in the constant temperature tank 11 more evenly mixed, the constant temperature tank 11 is equipped with a stirring paddle 17, which is driven by a second motor 12. The power output end of the second motor 12 is connected to the stirring paddle 17 to provide rotational power for the stirring paddle 17.

[0034] In order to achieve efficient and stable grinding of gold waste, the driving mechanism of the grinding chamber 1 includes a first motor 2, a pulley 3 and a synchronous belt 4. The power output of the first motor 2 drives the grinding components in the grinding chamber 1 to rotate at high speed through the transmission cooperation between the pulley 3 and the synchronous belt 4.

[0035] In order to achieve orderly collection and discharge of waste liquid, a collection box 16 is provided below the pull-out mechanism 10. The collection box 16 is used to receive and temporarily store the waste liquid flowing out of the filter box 1001. The collection box 16 is also connected to a drain pipe 15 for discharging the collected waste liquid in a unified manner.

[0036] Working principle: When the recycling process is started, the gold waste residue is first put into the grinding chamber 1 through the feed inlet 5; the first motor 2 is started, and its output power is driven by the pulley 3 and the synchronous belt 4 to drive the grinding components in the grinding chamber 1 to rotate at high speed, grinding the blocky waste residue into powder, thereby increasing the contact area between the gold and the subsequent leaching agent. The entire grinding device is fixedly supported above the constant temperature tank 11 by the bracket 8 to ensure that the grinding process is stable and without shaking; after grinding is completed, the first valve 7 is opened, and the finely ground waste residue is directionally transported to the constant temperature tank 11 through the transmission pipe 6; after the waste residue enters the constant temperature tank 11, the second motor 12 is started, and its power output end drives the stirring paddle 17 to rotate in the constant temperature tank 11, so that the waste residue powder is evenly distributed; a certain amount of environmentally friendly leaching agent is added into the tank through the liquid inlet pipe 13, and the mixture is stirred for one to two hours at the appropriate reaction temperature maintained in the constant temperature tank 11, so that the gold is fully dissolved from the waste residue into a gold-containing solution.

[0037] After the leaching reaction is completed, zinc powder needs to be added into the constant temperature tank 11 through the sealing mechanism 9. The operator holds the first handle 903 and flips the cover 902 around the rotating shaft 907 to open the feeding port 901. The first fixed seat 904 and the second fixed seat 905 are tightly fixed to the main body of the device by the nut 908. The limiting rod 906 slides in the reserved hole of the first fixed seat 904 to precisely limit the flipping angle of the cover 902, which not only ensures the convenience of feeding, but also effectively prevents the overflow of waste residue dust or the volatilization of leaching agent.

[0038] After the reaction is complete, the second valve 14 is opened. The material that has completed the reaction in the constant temperature tank 11 is filtered by the pull mechanism 10, and the waste liquid flows into the collection box 16 for temporary storage and is finally discharged through the drain pipe 15. The remaining solid gold material is separated into solid and liquid by the pull mechanism 10. This mechanism consists of a filter box 1001, a slide rail 1002, a guide rail 1003, and a second handle 1004. The operator holds the second handle 1004, which can drive the filter box 1001 to be pulled smoothly along the slide rail 1002 and the guide rail 1003. The filter structure built into the filter box 1001 can efficiently intercept solid gold material. The pull-out design not only makes it easy to quickly clean the residue, but also makes it easy to maintain the filter.
