Description

Technical Field

[0001] The present invention relates to the technical field of smelting and recycling, and particularly to a device for smelting and recycling waste residues generated in the process of wet zinc smelting. Background Art

[0002] In the process of wet zinc smelting, the generated waste residues are usually called zinc slag. These zinc slag contain other metals and impurities that are not extracted during the leaching and electrowinning processes of zinc. To treat these waste residues, devices are usually used for smelting and recycling.

[0003] The patent with the patent publication number CN211872068U relates to a device for smelting and recycling gold, silver, copper, and lead in waste residues generated in the process of wet zinc smelting, including a cavity, a burner, a base, and a discharge port. The top of the base is fixedly connected with a cavity, and support rods are fixedly connected at the four corners of the bottom of the cavity. A screening structure is fixedly connected between the support rods, and a discharge port is arranged at the bottom of the cavity. This patent realizes the rapid loading and unloading of materials through a filling structure. First, the discharge plate is pulled out from the bottom slide rail under the action of a pull rod and a slider for loading. The waste slag is placed into the discharge groove of the discharge plate. Multiple through holes are arranged on the surface of the discharge plate and the discharge groove, so that the waste slag will fall out through the through holes during the high-temperature smelting process. After the waste slag is placed, the discharge plate is integrally slid into the cavity from the slide rail under the action of the pull rod and the slider for smelting. At this time, the burner is started to carry out high-temperature smelting on the waste slag to complete the recovery of metal substances.

[0004] In the above patent, after the waste slag is placed, the discharge plate is integrally slid into the cavity from the slide rail under the action of a pull rod and a slider for smelting. At this time, the burner is started to carry out high-temperature smelting on the waste slag to complete the recovery of metal substances. However, before smelting, the zinc ore needs to be immersed in a leaching tank and treated with a leaching solution. Not all substances in the leaching tank will be completely dissolved, and some impurities and non-zinc substances will remain in the leaching waste residue. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device for smelting and recycling waste residues generated in the process of wet zinc smelting, and solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A device for smelting and recycling waste residues generated in the process of wet zinc smelting, including a body, further including a decomposition device and a separation device. A sulfuric acid tank is fixedly installed at the top of the body, and an observation window is arranged on the surface of the body. Among them, the decomposition device includes a slide rail, a linear motor, a leaching tank, a rotating plate, a fixed block, a driving motor and a sliding plate. Sulfuric acid is added into the leaching tank through the sulfuric acid tank, and then the leaching tank is driven to swing left and right by the linear motor. By swinging the leaching tank left and right, the mass transfer rate in the liquid can be increased, and the contact surface area between the liquid and the solid can be increased, thereby improving the reaction rate and work efficiency. The slide rail is fixedly installed on the inner wall of the body, the linear motor is slidably installed on the surface of the slide rail, the leaching tank is fixedly installed on the top of the linear motor, the rotating plate is rotatably installed on the inner wall of the body, the fixed block is fixedly installed on the inner wall of the leaching tank, the driving motor is fixedly installed on the surface of the body, and the sliding plate is slidably installed on the top of the driving motor. When the leaching tank moves left and right, it will drive the fixed block to move left and right. During the left and right movement of the fixed block, it will contact the rotating plate, and the movement of the fixed block will push the rotating plate to rotate upward. The upward rotation of the rotating plate can help maintain the uniform distribution of the reaction materials, prevent the local reaction rate from being too fast or too slow, and thus improve the uniformity of the reaction effect.

[0007] According to the above technical solution, the leaching tank is arranged at the bottom of the sulfuric acid tank. A first torsion spring is arranged between the rotating plate and the body, and the sliding plate is arranged at the bottom of the leaching tank. The rotating plate is reset by the first torsion spring.

[0008] According to the above technical solution, the separation device includes an elastic telescopic plate, a short rod and a filter plate. The driving motor is started to drive the sliding plate to move away from each other. When the sliding plate moves away from each other, the leaching tank is opened, and the waste residues remaining after the reaction fall onto the filter plate. The elastic telescopic plate is fixedly installed at the bottom of the sliding plate, the short rod is fixedly installed at the free end of the elastic telescopic plate, the filter plate is fixedly installed on the inner wall of the body, and the filter plate is arranged at the bottom of the sliding plate to prevent the waste residues from being mixed in the leaching solution and affecting the subsequent purification of the leaching solution.

[0009] According to the above technical solution, a chute is arranged on the inner wall of the body. A rotating shaft is rotatably installed on the surface of the chute, a trapezoidal block is fixedly installed on the surface of the rotating shaft, a limiting block is arranged on the surface of the chute, and the limiting block is arranged above the trapezoidal block. A second torsion spring is arranged between the chute and the rotating shaft. When the sliding plate moves away from each other, it will drive the elastic telescopic plate to move away from each other. When the elastic telescopic plate moves away from each other, it will drive the short rod to move away from each other along the chute. When the short rod moves away from each other along the chute, it will contact the inclined surface of the chute, preventing the waste residues from being pushed towards the middle during the reset process of the elastic telescopic plate and failing to achieve the effect of collecting the waste residues. The rotating shaft is reset by the second torsion spring.

[0010] According to the above technical solution, it further includes a collection device and an adsorption device. The collection device includes a short board, a sliding board, an L-shaped long rod, a triangular block, and a collection box. When the free end of the elastic telescopic board contracts, it drives the short board to move upward. When the short board moves upward, it drives the sliding board to move upward. When the sliding board moves upward, it drives the L-shaped long rod to move upward. When the L-shaped long rod moves upward, it contacts the inclined surface of the triangular block. The short board is fixedly installed at the free end of the elastic telescopic board. The sliding board is slidably installed on the inner wall of the machine body. The L-shaped long rod is fixedly installed at the bottom of the sliding board. The triangular block is slidably installed on the inner wall of the machine body. A groove is formed on the surface of the machine body. The collection box is fixedly installed on the surface of the machine body. A first spring is arranged between the sliding board and the machine body, and a second spring is arranged between the triangular block and the machine body, preventing waste residue from accumulating at the outlet of the collection box and affecting the collection of waste residue by the collection box. The sliding board is driven to reset by the first spring, and the triangular block is driven to reset by the second spring.

[0011] According to the above technical solution, a runner is fixedly installed on the inner wall of the collection box, and a rotating plate is rotatably installed on the inner wall of the collection box. One end of a connecting rope is hinged to the top of the triangular block, and the other end of the connecting rope is fixedly installed on the surface of the rotating plate. A third torsion spring is arranged between the collection box and the rotating plate. When the triangular block moves towards the inside of the collection box, it drives the connecting rope to move towards the inside of the collection box. When the connecting rope moves towards the inside of the collection box, it drives the rotating plate to rotate upward, preventing waste residue from accumulating too high and affecting the storage space of the collection box, and at the same time improving the collection efficiency. The rotating plate is driven to reset by the third torsion spring.

[0012] According to the above technical solution, the adsorption device includes an exhaust fan, an exhaust duct, a connecting ring, a fan blade, and an activated carbon plate. The exhaust fan is used to absorb the harmful gases generated by the reaction. When inhaling, it drives the fan blade to rotate. When the fan blade rotates, it drives the activated carbon plate to rotate. The exhaust duct fixedly penetrates the surface of the machine body. The exhaust fan is arranged on the surface of the exhaust duct. The connecting ring is fixedly installed on the inner wall of the exhaust duct. The fan blade is rotatably installed on the inner wall of the connecting ring. The activated carbon plate is fixedly installed on the surface of the fan blade. The rotation of the activated carbon plate helps to achieve a more uniform adsorption distribution. The uniform distribution can ensure that the entire surface of the activated carbon participates in the adsorption process.

[0013] According to the above technical solution, a fixing frame is fixedly installed at the top of the exhaust duct, and a connecting frame is fixedly installed at the top of the exhaust fan. The connecting frame is rotatably installed on the surface of the fixing frame. When the activated carbon plate needs to be replaced, the exhaust fan is rotated upward to open the exhaust duct, and the activated carbon plate is replaced, preventing the adsorption effect from decreasing due to long-term use of the activated carbon plate.

[0014] The present invention provides a device for treating waste residue generated in the process of wet zinc smelting and recycling. It has the following beneficial effects: In this invention, zinc ore is smelted by adding sulfuric acid into the leaching tank. While smelting, the leaching tank sways from side to side. The swaying can increase the mass transfer rate in the liquid. During the leaching process, sulfuric acid needs to react with solid ore particles. By swaying, the contact surface area between the liquid and the solid can be increased, thus enhancing the reaction rate. Meanwhile, during the swaying process, the rotating plate will be driven to rotate, which helps to maintain the uniform distribution of the reaction materials, preventing the local reaction rate from being too fast or too slow, and thus improving the uniformity of the reaction effect.

[0015] In this invention, the driving motor drives the sliding plate to open, enabling the un-decomposed metal waste residue after the reaction to fall onto the filter plate. At the same time, the sliding plate will drive the elastic telescopic plate to push the metal waste residue remaining from the previous time into the collection box, preventing the waste residue from mixing in the leaching solution and affecting the subsequent purification of the leaching solution. Meanwhile, when the sliding plate resets, the free end of the elastic telescopic plate can be contracted through the trapezoidal block and the rotating shaft, preventing the waste residue from being pushed towards the middle during the reset process and failing to achieve the effect of collecting the waste residue.

[0016] In this invention, the contraction of the free end of the elastic telescopic plate drives the triangular block to push towards the inside of the collection box, preventing the waste residue from accumulating at the outlet of the collection box and affecting the collection of the waste residue by the collection box. Meanwhile, the movement of the triangular block will drive the rotating plate to push the waste residue towards the inside of the collection box, preventing the waste residue from piling up too high and affecting the storage space of the collection box, while also improving the collection efficiency.

[0017] In this invention, the exhaust fan sucks the harmful gases generated after the reaction into the exhaust duct, and then the activated carbon plate adsorbs the effective gases. While adsorbing, the fan blades will drive the activated carbon plate to rotate. The rotating activated carbon plate helps to achieve a more uniform adsorption distribution. The uniform distribution can ensure that the entire surface of the activated carbon participates in the adsorption process, preventing the appearance of dead corners or underutilized areas. Meanwhile, when the activated carbon plate needs to be replaced, the exhaust fan can be rotated upwards to replace the activated carbon plate, preventing the adsorption effect from decreasing due to long-term use of the activated carbon plate.

Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-6, an embodiment of the present invention is: a device for smelting and recycling waste residues generated in the process of hydrometallurgical zinc smelting, including a body 1, further including a decomposition device and a separation device.

Sulfuric acid is added into the leaching tank 43 through the sulfuric acid tank 2, and then the leaching tank 43 is driven to shake left and right by the linear motor 42. By shaking the leaching tank 43 left and right, the mass transfer rate in the liquid can be increased, and the contact surface area between the liquid and the solid can be increased, thereby improving the reaction rate and work efficiency. The slide rail 41 is fixedly installed on the inner wall of the body 1, the linear motor 42 is slidably installed on the surface of the slide rail 41, the leaching tank 43 is fixedly installed on the top of the linear motor 42, the rotating plate 44 is rotatably installed on the inner wall of the body 1, the fixed block 45 is fixedly installed on the inner wall of the leaching tank 43, the driving motor 46 is fixedly installed on the surface of the body 1, the sliding plate 47 is slidably installed on the top of the driving motor 46. When the leaching tank 43 moves left and right, it will drive the fixed block 45 to move left and right. During the left and right movement of the fixed block 45, it will contact the rotating plate 44, and the movement of the fixed block 45 will push the rotating plate 44 to rotate upward. The upward rotation of the rotating plate 44 can help maintain the uniform distribution of the reaction materials, prevent the local reaction rate from being too fast or too slow, and thus improve the uniformity of the reaction effect.

[0022] The leaching tank 43 is arranged at the bottom of the sulfuric acid tank 2. A first torsion spring is arranged between the rotating plate 44 and the body 1. The sliding plate 47 is arranged at the bottom of the leaching tank 43, and the rotating plate 44 is driven to reset by the first torsion spring.

[0023] The separation device includes an elastic telescopic plate 51, a short rod 52 and a filter plate 53. The driving motor 46 is started to drive the sliding plate 47 to move backward. The backward movement of the sliding plate 47 opens the leaching tank 43 so that the remaining waste residues after the reaction fall onto the filter plate 53. The elastic telescopic plate 51 is fixedly installed at the bottom of the sliding plate 47, the short rod 52 is fixedly installed at the free end of the elastic telescopic plate 51, the filter plate 53 is fixedly installed on the inner wall of the body 1, and the filter plate 53 is arranged at the bottom of the sliding plate 47 to prevent the waste residues from being mixed in the leaching solution and affecting the subsequent purification of the leaching solution.

[0024] A chute 54 is provided on the inner wall of the machine body 1. A rotating shaft 56 is rotatably installed on the surface of the chute 54. A trapezoidal block 55 is fixedly installed on the surface of the rotating shaft 56. A limit block 57 is provided on the surface of the chute 54. The limit block 57 is arranged above the trapezoidal block 55. A second torsion spring is provided between the chute 54 and the rotating shaft 56. When the sliding plate 47 moves away from each other, it will drive the elastic telescopic plate 51 to move away from each other. When the elastic telescopic plate 51 moves away from each other, it will drive the short rod 52 to move away from each other along the chute 54. When the short rod 52 moves away from each other along the chute 54, it will contact the inclined surface of the chute 54, preventing the waste residue from being pushed towards the middle during the reset process of the elastic telescopic plate 51 and failing to achieve the effect of collecting the waste residue. The second torsion spring drives the rotating shaft 56 to reset.

[0025] During the operation of this embodiment, sulfuric acid is added into the leaching tank 43 through the sulfuric acid tank 2, and then the linear motor 42 drives the leaching tank 43 to shake left and right. By shaking the leaching tank 43 left and right, the shaking can improve the mass transfer rate in the liquid, increase the contact surface area between the liquid and the solid, thereby improving the reaction rate and work efficiency. When the leaching tank 43 moves left and right, it will drive the fixed block 45 to move left and right. During the left and right movement of the fixed block 45, it will contact the rotating plate 44. The movement of the fixed block 45 will push the rotating plate 44 to rotate upward. When the rotating plate 44 rotates upward, the rotating plate 44 can push the sulfuric acid on the inner wall to shake, which helps to maintain the uniform distribution of the reaction materials and prevent the local reaction rate from being too fast or too slow, thereby improving the uniformity of the reaction effect.

[0026] When the reaction is completed, the driving motor 46 is started to drive the sliding plate 47 to move away from each other. The sliding plate 47 moving away from each other opens the leaching tank 43 so that the waste residue remaining after the reaction falls onto the filter plate 53, preventing the waste residue from mixing in the leaching solution and affecting the subsequent purification of the leaching solution. At the same time, when the sliding plate 47 moves away from each other, it will drive the elastic telescopic plate 51 to move away from each other. When the elastic telescopic plate 51 moves away from each other, it will drive the short rod 52 to move away from each other along the chute 54. When the short rod 52 moves away from each other along the chute 54, it will contact the inclined surface of the chute 54. When the short rod 52 rises along the inclined surface, it will drive the free end of the elastic telescopic plate 51 to contract. During the contraction process of the free end of the elastic telescopic plate 51, the short rod 52 contacts the trapezoidal block 55, and the short rod 52 will push the trapezoidal block 55 to rotate upward. When the contact with the trapezoidal block 55 is lost, the second torsion spring between the rotating shaft 56 and the chute 54 will drive the trapezoidal block 55 to reset, and the trapezoidal block 55 resetting will block the short rod 52, preventing the waste residue from being pushed towards the middle during the reset process of the elastic telescopic plate 51 and failing to achieve the effect of collecting the waste residue.
