Description

Technical Field

[0001] This utility model relates to the field of leaching reactor technology, and in particular to a material dispersion structure for a nickel-cobalt waste leaching reactor. Background Technology

[0002] Nickel-cobalt waste refers to industrial and waste product derivatives containing nickel and cobalt elements. Its main sources include power batteries for new energy vehicles, consumer electronics batteries (such as mobile phone and laptop batteries), metallurgical production waste slag, electroplating sludge, and waste alloy components.

[0003] Existing reactors rely solely on the rotation of bottom paddles, resulting in insufficient shear force on agglomerated particles that easily settle and accumulate at the bottom, leading to slow renewal of the leachate-metal interface. This device, lacking a vibration coordination structure, cannot immediately disperse the agglomerates, resulting in long leaching cycles and large fluctuations in nickel-cobalt extraction rates. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a material dispersion structure for a nickel-cobalt waste leaching reactor.

[0005] This utility model is achieved using the following technical solution: a material dispersion structure for a nickel-cobalt waste leaching reactor, comprising a reaction tank, a top cover installed on the top of the reaction tank, a drive motor fixedly connected to the top of the top cover by bolts, a rotating rod fixedly connected to the output end of the drive motor, a lever fixedly connected to the surface of the rotating rod, an inner plate fixedly connected to the inner wall of the reaction tank, a sliding rod fixedly connected to the top of the inner plate, a spring sleeved on the surface of the sliding rod, an annular plate slidably connected to the surface of the sliding rod, a placement cylinder fixedly connected to the bottom of the annular plate, and a trapezoidal block fixedly connected to the top of the annular plate.

[0006] Through the above technical solution, the relative motion between the lever and the trapezoidal block is used to convert the rotational kinetic energy into intermittent lifting and lowering vibration of the placement cylinder, so that the material inside the cylinder is continuously thrown up and falling back, achieving orderly dispersion by first vibrating to break up the agglomerates and then leaching them out.

[0007] As a further improvement to the above solution, the number of levers is set to four, and the four levers are arranged in a circular array at the top of the rotating rod. The number of slide rods is set to four, and the four slide rods are arranged in a circular array at the top of the inner plate.

[0008] With the above technical solution, the four levers and four slides are arranged in a circular array, which ensures that the pushing force of the levers on the trapezoidal block is evenly transmitted along the circumference, the placement cylinder is balanced by force, avoids uneven loading and jamming, and the vibration is more evenly dispersed.

[0009] As a further improvement to the above solution, the bottom of the spring is fixedly connected to the top of the inner plate, the top of the spring is in contact with the bottom of the annular plate, and the bottom of the placement cylinder is provided with several holes arranged in a circular array.

[0010] Through the above technical solution, the bottom end of the spring is fixed to the inner plate and the top end contacts the annular plate to form an elastic reset pair, ensuring that the cylinder can rebound instantly after the lever is separated from the trapezoidal block; the holes evenly distributed at the bottom of the cylinder allow the fine particles after vibration to leak out in time and prevent them from accumulating again.

[0011] As a further improvement to the above scheme, the distance between the trapezoidal block and the top of the annular plate gradually increases from right to left.

[0012] Through the above technical solution, the top surface of the trapezoidal block adopts an inclined surface that gradually rises from right to left, so that the lever generates a controllable progressive downward pressure on the placement cylinder during the climbing process, reducing impact noise and extending the life of the spring and sliding pair.

[0013] As a further improvement to the above solution, a connecting column is fixedly connected to the bottom of the rotating rod, and a stirring rod is fixedly connected to the surface of the connecting column.

[0014] Through the above technical solution, a connecting column and a stirring rod are added to the bottom of the rotating rod, which radially stirs the material while vibrating and dispersing it, forming a composite dispersion field that vibrates and stirs at the same time, thereby improving the penetration efficiency of the leachate.

[0015] As a further improvement to the above solution, the number of connecting posts is set to several, and the several connecting posts are centrally symmetrically distributed on the front side of the connecting posts.

[0016] Through the above technical solution, several connecting columns are arranged in a centrally symmetrical manner, so that the stirring rod forms a multi-point symmetrical flow field inside the cylinder, eliminating the stirring dead zone and ensuring the uniform dispersion of materials.

[0017] As a further improvement to the above solution, a handle is fixedly connected to the top of the annular plate, a feed pipe is installed on the top of the top cover, a discharge pipe is installed at the bottom of the reaction vessel, and a bracket is fixedly connected to the surface of the reaction vessel.

[0018] With the above technical solution, a handle is set on the top of the annular plate, which can be quickly lifted to unload or clean the placement cylinder after the machine stops; the feed pipe, discharge pipe and support are integrated into the tank body to realize continuous feeding and discharging and overall stable support, improving the convenience of operation.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a linkage mechanism consisting of a lever, a trapezoidal block, a spring, and an annular plate. During operation, the lever periodically pushes the trapezoidal block along with the rotating rod, causing the placement cylinder to overcome the spring force and rebound instantly after the lever disengages. This generates high-frequency micro-vibration on the material inside the cylinder, achieving the effect of continuously dispersing agglomerated particles and significantly improving the uniformity of contact between the leachate and the material.

[0020] This invention features a connecting column and a stirring rod that rotate synchronously with the rotating rod. During operation, the stirring rod continuously agitates inside the placement cylinder, working in conjunction with the vibration and dispersion effect at the bottom of the cylinder to achieve secondary shearing and dispersion of the material, shorten the leaching time, and improve the nickel-cobalt leaching rate.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Example: Please combine Figure 1-4 The material dispersion structure of a nickel-cobalt waste leaching reactor according to this embodiment includes a reaction tank 1, a top cover 2 installed on the top of the reaction tank 1, a drive motor 3 fixedly connected to the top of the top cover 2 by bolts, a rotating rod 4 fixedly connected to the output end of the drive motor 3, a lever 5 fixedly connected to the surface of the rotating rod 4, an inner plate 6 fixedly connected to the inner wall of the reaction tank 1, a sliding rod 7 fixedly connected to the top of the inner plate 6, a spring 8 sleeved on the surface of the sliding rod 7, an annular plate 9 slidably connected to the surface of the sliding rod 7, a placement cylinder 10 fixedly connected to the bottom of the annular plate 9, and a trapezoidal block 11 fixedly connected to the top of the annular plate 9.

[0025] During dispersion, the drive motor 3 is started, and the output end of the drive motor 3 drives the rotating rod 4 to rotate. When the rotating rod 4 rotates, it will contact the surface of the trapezoidal block 11 and move from right to left. Since the height of the lever 5 is fixed, the distance between the trapezoidal block 11 and the bottom of the annular plate 9 gradually increases from right to left. At this time, when the lever 5 moves on the surface of the trapezoidal block 11, it will move the placement cylinder 10 downward. The annular plate 9 will squeeze the spring 8. When the lever 5 is disengaged from the surface of the trapezoidal block 11, the placement cylinder 10 will rebound, vibrating the material at the bottom of the placement cylinder 10 and dispersing it.

[0026] There are four levers 5, which are arranged in a circular array around the top of the rotating rod 4. There are also four slide rods 7, which are arranged in a circular array around the top of the inner plate 6. The arrangement of the four levers 5 and the four slide rods 7 in a circular array ensures that the pushing force of the levers 5 on the trapezoidal block 11 is evenly transmitted along the circumference, the placement cylinder 10 is balanced by force, avoids uneven loading and jamming, and the vibration is more dispersed and stable.

[0027] The bottom of the spring 8 is fixedly connected to the top of the inner plate 6, and the top of the spring 8 is in contact with the bottom of the annular plate 9. The bottom of the placement cylinder 10 is provided with several holes arranged in a circular array.

[0028] The distance between the trapezoidal block 11 and the top of the annular plate 9 gradually increases from right to left. The top surface of the trapezoidal block 11 adopts an inclined surface that gradually rises from right to left, so that the lever 5 generates a controllable progressive downward pressure on the placement cylinder 10 during the climbing process, reducing impact noise and extending the life of the spring 8 and the sliding pair.

[0029] A connecting column 12 is fixedly connected to the bottom of the rotating rod 4, and a stirring rod 13 is fixedly connected to the surface of the connecting column 12. The addition of the connecting column 12 and the stirring rod 13 to the bottom of the rotating rod 4 allows for radial stirring of the material while it is vibrating and dispersing, forming a composite dispersion field that is both vibrating and stirring, thereby improving the penetration efficiency of the leachate.

[0030] The number of connecting columns 12 is set to be several, and the connecting columns 12 are centrally symmetrically distributed on the front side of the connecting columns 12. The connecting columns 12 are arranged in a centrally symmetrical manner, so that the stirring rod 13 forms a multi-point symmetrical flow field in the cylinder, eliminating the stirring dead corners and ensuring the uniform dispersion of materials.

[0031] A handle 14 is fixedly connected to the top of the annular plate 9, a feed pipe 15 is installed on the top of the top cover 2, a discharge pipe 16 is installed at the bottom of the reaction vessel 1, and a bracket 17 is fixedly connected to the surface of the reaction vessel 1.

[0032] The implementation principle of the material dispersion structure of the nickel-cobalt waste leaching reactor in this application embodiment is as follows: When the material leaching reaction is carried out, the material and leaching liquid are first sent into the interior of the reaction tank 1, so that the material is located inside the placement cylinder 10. The drive motor 3 is started, and the output end of the drive motor 3 drives the rotating rod 4 to rotate. When the rotating rod 4 rotates, it will contact the surface of the trapezoidal block 11 and move from right to left. Since the height of the lever 5 is fixed, the distance between the trapezoidal block 11 and the bottom of the annular plate 9 gradually increases from right to left. At this time, when the lever 5 moves on the surface of the trapezoidal block 11, it will move the placement cylinder 10 downward. The annular plate 9 will squeeze the spring 8. When the lever 5 is disengaged from the surface of the trapezoidal block 11, the placement cylinder 10 rebounds, vibrating the material at the bottom of the placement cylinder 10 and dispersing it.

[0033] When the rotating rod 4 rotates, it synchronously drives the connecting column 12 to rotate, and the rotating column 12 synchronously drives the stirring rod 13 to rotate, so that the stirring rod 13 stirs, mixes and disperses the material inside the placement cylinder 10.

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
