[0002] Nickel carbonate spent catalysts are widely used in the chemical, pharmaceutical and new energy fields. If they are discarded directly after they fail, it will not only waste nickel resources, but may also pollute the environment due to the leaching of heavy metal ions.

[0003] Among existing recycling technologies, wet processes have high reagent consumption and high wastewater treatment costs; traditional pyrometallurgical processes mostly rely on a single smelting device, which has drawbacks such as uneven material mixing and high equipment energy consumption. Summary of the Invention

The pretreatment component includes a mixing mechanism for mixing waste catalyst powder and additives. A conveying mechanism is disposed below the mixing mechanism for conveying the waste catalyst after it has been mixed by the mixing mechanism. A waste heat recovery assembly is disposed on the outside of the smelting furnace. The waste heat recovery assembly includes an insulation jacket, a circulation pipe is disposed inside the insulation jacket, water flows through the circulation pipe, a circulation pump is disposed on the circulation pipe, and a heat exchanger is disposed on the outside of the conveying mechanism. The heat exchanger is connected to the circulation pipe, and a fan is disposed on the heat exchanger facing the conveying mechanism.

[0006] As described above, the mixing mechanism includes a material cylinder, a hopper is provided on the upper side of one end of the material cylinder, and two rotating shafts are arranged side by side inside the material cylinder.

Multiple stirring rods are evenly arranged on the outer side of the rotating shafts, and a discharge pipe is provided on the lower side of the end of the material cylinder away from the hopper.

[0007] As mentioned above, the stirring rod is provided with shovels and buckets at intervals.

[0008] As described above, the conveying mechanism includes a fixed plate, which is inclinedly mounted on the mounting frame. A sliding plate is slidably mounted on the upper end of the fixed plate. One end of the sliding plate is connected to the extended end of the drive cylinder via a steel wire rope. A reversing wheel is mounted on the steel wire rope. A conveyor belt is mounted on the lower end of the fixed plate. The drive cylinder, the reversing wheel, and the conveyor belt are all mounted on the mounting frame, and the end of the conveyor belt is connected to the feed inlet of the smelting furnace.

[0009] As described above, a receiving plate is provided at the upper end of the sliding plate, and a return spring is provided between the receiving plate and the sliding plate. A material discharge port is provided at the lower end of the fixed plate, and the material discharge port is located above the starting end of the conveyor belt.

[0010] As described above, the fixed plate and the sliding plate are both provided with semi-circular grooves on their sides that are close to each other, and the semi-circular grooves on the fixed plate and the sliding plate are arranged correspondingly.

[0012] As mentioned above, multiple partitions are provided within the notch by means of snap-fit.

[0013] In the above technical solution, the beneficial effects of the present invention are as follows: 1. The pretreatment component of this invention uses a mixing mechanism to stir the waste catalyst powder and additives, ensuring that the waste catalyst powder and additives are fully mixed. After stirring, the mixture of waste catalyst powder and additives is conveyed by a conveying mechanism so that the mixed waste catalyst powder and additives are continuously fed into the smelting furnace, thereby improving the recycling efficiency of the equipment. This invention collects the waste heat emitted by the smelting furnace through the water flow in the insulation jacket and circulation pipe, and exchanges the heat collected by the water flow with the air at the fan through a heat exchanger. The fan then sprays the hot air onto the mixed waste catalyst powder and additives conveyed by the conveying mechanism, so that the waste heat collected by the water flow in the insulation jacket and circulation pipe can preheat and dry the mixed waste catalyst powder and additives.

Therefore, they should not be construed as limitations on this invention.

[0019] like Figures 1-5 As shown in the figure, an embodiment of the present invention provides a waste catalyst recycling and treatment device containing nickel carbonate, including a mounting frame 1, a smelting furnace 2 disposed in the middle of the mounting frame 1, and further including: The pretreatment component 3 is located at the upper end of the mounting frame 1. The pretreatment component 3 includes a mixing mechanism 30, which is used to mix waste catalyst powder and additives. A conveying mechanism 31 is provided below the mixing mechanism 30, which can convey the waste catalyst after it has been mixed by the mixing mechanism 30. Waste heat recovery component 4 is located outside the smelting furnace 2. Waste heat recovery component 4 includes an insulation jacket 40, a circulation pipe 41 is provided inside the insulation jacket 40, water flows inside the circulation pipe 41, a circulation pump 42 is provided on the circulation pipe 41, and a heat exchanger 43 is provided outside the conveying mechanism 31. The heat exchanger 43 is connected to the circulation pipe 41, and a fan 44 is provided on the heat exchanger, with the fan 44 facing the conveying mechanism 31.

[0020] In another embodiment of the present invention, the mixing mechanism 30 includes a material cylinder 300, a hopper 301 is provided on the upper side of one end of the material cylinder 300, and two rotating shafts 302 are arranged in parallel inside the material cylinder 300. At least one rotating shaft 302 is provided with a mixing motor 303 at one end, and each end of the two rotating shafts 302 is provided with a gear. The two gears mesh with each other. A plurality of stirring rods 304 are evenly arranged on the outer side of the rotating shafts 302, and a discharge pipe 305 is provided on the lower side of the end of the material cylinder 300 away from the hopper 301. The specific implementation method is as follows: When recycling waste catalyst, the waste catalyst ground into powder is first added from hopper 301 into material cylinder 300, and additives (collecting agent, reducing agent and slagging agent) are added from hopper 301 into material cylinder 300 at the same time. At this time, the mixing motor 303 drives the rotating shaft 302 connected to it to rotate, and the two meshing gears drive another rotating shaft 302 to rotate synchronously, so that the rotating shaft 302 drives the stirring rod 304 to rotate and stir the waste catalyst powder, so that the waste catalyst powder and additives are fully mixed. During the rotation and stirring process, the rotating shaft 302 drives the stirring rod 304 to move the waste catalyst powder towards the discharge pipe 305 so that the mixed waste catalyst powder is discharged from the discharge pipe 305.

[0021] In another embodiment of the present invention, a shovel plate 3040 and a bucket 3041 are arranged at intervals on the stirring rod 304; The specific implementation method is as follows: When the mixing motor 303 drives the stirring rod 304 to rotate and stir the waste catalyst powder through the rotating shaft 302, the stirring rod 304 can drive the shovel plate 3040 set on it to shovel up and flip the waste catalyst powder in the material cylinder 300. At the same time, the rotating shaft 302 drives the bucket 3041 through the stirring rod 304 to throw up the waste catalyst powder in the material cylinder 300 so that the waste catalyst powder and the additives are fully mixed.

[0022] In another embodiment of the present invention, the conveying mechanism 31 includes a fixed plate 310, which is inclinedly disposed on the mounting frame 1. A sliding plate 311 is slidably disposed on the upper end of the fixed plate 310. One end of the sliding plate 311 is connected to the extended end of the drive cylinder 313 via a wire rope 312. A reversing wheel 314 is disposed on the wire rope 312. A conveyor belt 315 is disposed on the lower end of the fixed plate 310. The drive cylinder 313, the reversing wheel 314 and the conveyor belt 315 are all disposed on the mounting frame 1, and the end of the conveyor belt 315 is connected to the feed inlet of the smelting furnace 2. The specific implementation method is as follows: After the waste catalyst powder is mixed with the additive, it is discharged through the discharge pipe 305 and falls between the fixed plate 310 and the sliding plate 311. At this time, the extension end of the drive cylinder 313 extends, which loosens the wire rope 312. As a result, the sliding plate 311 moves down along the fixed plate 310 under its own weight, and slides down to the lowest point of the fixed plate 310. After the sliding plate 311 slides down to the lowest point of the fixed plate 310, the extension end of the drive cylinder 313 retracts, which pulls the wire rope 312, causing the wire rope 312 to pull the sliding plate 311 to slide along the fixed plate 310. The upward movement causes the sliding plate 311 to move from the low point of the fixed plate 310 to the high point of the fixed plate 310, thereby causing relative movement between the sliding plate 311 and the fixed plate 310. When the drive cylinder 313 drives the sliding plate 311 to move through the wire rope 312, the reversing wheel 314 guides the wire rope 312. At the same time, the sliding plate 311 and the fixed plate 310 rub the waste catalyst powder mixed with additives that enters between them, causing the waste catalyst powder mixed with additives to be kneaded into balls. The kneaded waste catalyst powder falls from the fixed plate 310 onto the conveyor belt 315, so that the conveyor belt 315 transports the kneaded waste catalyst powder.

[0023] In another embodiment of the present invention, a receiving plate 316 is provided at the upper end of the sliding plate 311, a return spring 317 is provided between the receiving plate 316 and the sliding plate 311, and a material discharge port 3100 is provided at the lower end of the fixed plate 310, the material discharge port 3100 being located above the starting end of the conveyor belt 315. The specific implementation method is as follows: When the waste catalyst powder is discharged from the discharge pipe 305 into the space between the sliding plate 311 and the fixed plate 310, in order to ensure that the waste catalyst powder can always fall between the sliding plate 311 and the fixed plate 310, a receiving plate 316 is used to receive and guide the waste catalyst powder falling from the discharge pipe 305, so that the waste catalyst powder falling on the receiving plate 316 can smoothly enter the space between the sliding plate 311 and the fixed plate 310, ensuring that the sliding plate 311 and the fixed plate 310 can knead the waste catalyst powder between them into a ball. At the same time, when the sliding plate 311 moves along the fixed plate 310, the return spring 317 can pull the sliding plate 311 to ensure that after the extension end of the drive cylinder 313 relaxes the wire rope 312, the return spring 317 drives the sliding plate 311 to reset. After the sliding plate 311 and the fixed plate 310 knead the waste catalyst powder between them into a ball, the ball-shaped waste catalyst powder can be separated from the sliding plate 311 and the fixed plate 310 and fall from the discharge port 3100 into the conveyor belt 315 so that the conveyor belt 315 can transport the ball-shaped waste catalyst powder.

[0024] In another embodiment of the present invention, a semi-circular groove 3101 is provided on the side of the fixed plate 310 and the sliding plate 311 that are close to each other, and the semi-circular grooves 3101 on the fixed plate 310 and the sliding plate 311 are arranged correspondingly, and the semi-circular groove 3101 on the fixed plate 310 is a rough surface, while the semi-circular groove 3101 on the sliding plate 311 is a smooth surface. The specific implementation method is as follows: the semi-circular grooves 3101 on the fixed plate 310 and the sliding plate 311 can form a complete cylinder. Thus, the fixed plate 310 and the sliding plate 311 knead the waste catalyst powder within the semi-circular grooves 3101 into balls. The rough surface of the semi-circular grooves 3101 on the fixed plate 310 reduces or even prevents the waste catalyst powder from falling between the fixed plate 310 and the sliding plate 311. The smooth surface of the semi-circular grooves 3101 on the sliding plate 311 facilitates kneading the waste catalyst powder within the semi-circular grooves 3101 into balls, and... The spherical waste catalyst is conveyed into the smelting furnace 2 via the conveyor belt 315 for smelting to recover the waste catalyst. In addition, when the conveyor belt 315 conveys the spherical waste catalyst, the smelting furnace 2 is kept warm by the insulation jacket 40. At the same time, the waste heat of the smelting furnace 2 is collected by the water flow in the circulation pipe 41. The circulation pump 42 can drive the water flow in the circulation pipe 41. When the water flows through the heat exchanger 43, the heat exchanger 43 exchanges the heat of the water and then sprays it onto the spherical waste catalyst on the conveyor belt 315 by the fan 44 for preheating and drying.

[0025] In another embodiment of the present invention, the conveying mechanism 31 further includes a connecting plate 318, on which a control plate 319 is provided. The control plate 319 is slidably disposed in the discharge pipe 305, and a notch 3190 is provided on the control plate 319. The specific implementation method is as follows: When the extended end of the drive cylinder 313 controls the sliding plate 311 to move along the fixed plate 310 via the wire rope 312, the extended end of the drive cylinder 313 can drive the connecting plate 318 to move synchronously, so that the connecting plate 318 drives the control plate 319 to slide along the discharge pipe 305. When the extended end of the drive cylinder 313 extends, the wire rope 312 is loosened so that the sliding plate 311 descends along the fixed plate 310. At the same time, when the extended end of the drive cylinder 313 extends, the notch 3190 of the control plate 319 is aligned with the discharge pipe 305 via the connecting plate 318. At this time, the waste catalyst powder after mixing with additives can fall from the discharge pipe 305 and the notch 3190 to the receiving plate 316. When the extended end of cylinder 313 retracts, the wire rope 312 pulls the sliding plate 311 upward along the fixed plate 310, causing the sliding plate 311 and the fixed plate 310 to knead the waste catalyst powder into balls. At the same time, when the extended end of cylinder 313 retracts, it drives the connecting plate 318 to move in the opposite direction, causing the connecting plate 318 to drive the control plate 319 to move in the opposite direction. This causes the control plate 319 to cause the notch 3190 to be misaligned with the discharge pipe 305. At this time, the waste catalyst powder mixed with additives cannot fall from the material pipe. Thus, when the driving cylinder 313 controls the sliding plate 311 to knead the waste catalyst powder into balls, the driving cylinder 313 can control the intermittent falling of the waste catalyst powder through the connecting plate 318 and the control plate 319.

[0026] In another embodiment of the present invention, a plurality of partitions 3191 are provided in the notch 3190 by means of snap-fit; The specific implementation method is as follows: multiple baffles 3191 are provided in the notch 3190. In this way, the size of the notch 3190 is controlled by controlling the number of baffles 3191 in the notch 3190, so that the baffles 3191 can control the amount of waste catalyst powder falling from the discharge pipe 305, and avoid the situation where too much waste catalyst powder falls in a short period of time, making it difficult for the sliding plate 311 and the fixed plate 310 to knead it into balls in time.

[0027] Working principle: During the recycling of spent catalyst, the powdered spent catalyst is first added from hopper 301 into material cylinder 300, and additives are simultaneously added from hopper 301 into material cylinder 300. At this time, the mixing motor 303 drives the connected rotating shaft 302 to rotate, and two meshing gears drive another rotating shaft 302 to rotate synchronously. This causes the rotating shaft 302 to drive the stirring rod 304 to rotate and stir the spent catalyst powder, so that the spent catalyst powder and additives are fully mixed. The rotating shaft 302 drives the stirring rod 304 to rotate. During the stirring process, the waste catalyst powder can be pushed towards the discharge pipe 305 so that the mixed waste catalyst powder can be discharged from the discharge pipe 305. When the mixing motor 303 drives the stirring rod 304 to rotate and stir the waste catalyst powder through the rotating shaft 302, the stirring rod 304 can drive the shovel plate 3040 set on it to shovel up and flip the waste catalyst powder in the material cylinder 300. At the same time, the rotating shaft 302 drives the bucket 3041 through the stirring rod 304 to throw up the waste catalyst powder in the material cylinder 300 so that the waste catalyst powder and the additive can be fully mixed. After the waste catalyst powder is mixed with the additives, it is discharged through the discharge pipe 305 and falls between the fixed plate 310 and the sliding plate 311. At this time, the extension end of the drive cylinder 313 extends, causing the extension end of the drive cylinder 313 to loosen the wire rope 312. As a result, the sliding plate 311 moves down along the fixed plate 310 under its own weight, causing the sliding plate 311 to slide down to the lowest point of the fixed plate 310. After the sliding plate 311 slides down to the lowest point of the fixed plate 310, the extension end of the drive cylinder 313 retracts, causing the extension end of the drive cylinder 313 to pull the wire rope 312, thereby causing the wire rope 312 to... Pulling the sliding plate 311 upwards along the fixed plate 310 causes it to move from the low point to the high point of the fixed plate 310, resulting in relative movement between the sliding plate 311 and the fixed plate 310. As the drive cylinder 313 moves the sliding plate 311 via the wire rope 312, the reversing wheel 314 guides the wire rope 312. Simultaneously, the sliding plate 311 and the fixed plate 310 rub the waste catalyst powder mixed with additives that enters between them, kneading the powder into spherical balls. These spherical balls of waste catalyst powder then move from the fixed plate... The waste catalyst powder, kneaded into granules, falls from the fixed plate 310 onto the conveyor belt 315, allowing the conveyor belt 315 to transport the granulated waste catalyst powder. As the waste catalyst powder flows through the discharge pipe 305 towards the space between the sliding plate 311 and the fixed plate 310, a receiving plate 316 receives and guides the waste catalyst powder falling from the discharge pipe 305. This ensures that the waste catalyst powder falling onto the receiving plate 316 can smoothly enter the space between the sliding plate 311 and the fixed plate 310, ensuring that the sliding plate 311 and the fixed plate 310 can effectively handle the waste catalyst powder. The waste catalyst powder is kneaded into balls between the two. At the same time, when the sliding plate 311 moves along the fixed plate 310, the return spring 317 can pull the sliding plate 311 to ensure that after the extension end of the drive cylinder 313 relaxes the wire rope 312, the return spring 317 drives the sliding plate 311 to return to its original position. After the sliding plate 311 and the fixed plate 310 knead the waste catalyst powder between them into balls, the ball-shaped waste catalyst powder can be separated from the sliding plate 311 and the fixed plate 310 and fall from the discharge port 3100 into the conveyor belt 315 so that the conveyor belt 315 can transport the ball-shaped waste catalyst powder.The semicircular grooves 3101 on the fixed plate 310 and the sliding plate 311 can form a complete cylinder. Thus, the fixed plate 310 and the sliding plate 311 knead the waste catalyst powder within the semicircular grooves 3101 into spheres. The rough surface of the semicircular grooves 3101 on the fixed plate 310 reduces or even prevents the waste catalyst powder from falling between the fixed plate 310 and the sliding plate 311. The smooth surface of the semicircular grooves 3101 on the sliding plate 311 facilitates the kneading of the waste catalyst powder within the semicircular grooves 3101 into spheres. These spheres of waste catalyst are then conveyed into the smelting furnace 2 by the conveyor belt 315 for smelting to recover the waste catalyst. Furthermore, when the conveyor belt 315 conveys the spheres of waste catalyst, it... The insulation jacket 40 insulates the smelting furnace 2 and collects the waste heat of the smelting furnace 2 through the water flow in the circulation pipe 41. The circulation pump 42 drives the water flow in the circulation pipe 41. When the water flows through the heat exchanger 43, the heat exchanger 43 exchanges the heat of the water and then sprays it onto the spherical waste catalyst on the conveyor belt 315 through the fan 44 for preheating and drying. When the extended end of the drive cylinder 313 controls the sliding plate 311 to move along the fixed plate 310 through the wire rope 312, the extended end of the drive cylinder 313 can drive the connecting plate 318 to move synchronously, so that the connecting plate 318 drives the control plate 319 to slide along the discharge pipe 305. When the extended end of the drive cylinder 313 extends, the wire rope 312... The sliding plate 311 is relaxed to allow it to descend along the fixed plate 310. Simultaneously, as the extended end of the drive cylinder 313 extends, it drives the notch 3190 of the control plate 319 to align with the discharge pipe 305 via the connecting plate 318. At this point, the waste catalyst powder mixed with additives can fall from the discharge pipe 305 and the notch 3190 onto the receiving plate 316. When the extended end of the drive cylinder 313 retracts, the wire rope 312 pulls the sliding plate 311 upwards along the fixed plate 310, causing the sliding plate 311 and the fixed plate 310 to knead the waste catalyst powder into balls. Simultaneously, the retraction of the extended end of the drive cylinder 313 causes the connecting plate 318 to move in the opposite direction, which in turn causes the control plate 319 to move in the opposite direction, thereby controlling... Plate 319 causes the notch 3190 to misalign with the discharge pipe 305. At this time, the waste catalyst powder mixed with additives cannot fall from the material pipe. Thus, when the driving cylinder 313 controls the sliding plate 311 to knead the waste catalyst powder into balls, the driving cylinder 313 can control the intermittent falling of the waste catalyst powder through the connecting plate 318 and the control plate 319. Multiple baffles 3191 are installed inside the notch 3190. Thus, by controlling the number of baffles 3191 inside the notch 3190, the size of the notch 3190 is controlled, so that the baffles 3191 control the amount of waste catalyst powder falling from the discharge pipe 305, avoiding a situation where too much waste catalyst powder falls in a short time, making it difficult for the sliding plate 311 and the fixed plate 310 to knead it into balls in time.

[0028] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
