Description

Technical Field

[0001] The invention relates to the technical field of reaction equipment, in particular to a reaction kettle for producing nickel sulfate solution extracted from waste batteries. Background Art

[0002] At present, when recycling waste batteries, a reactor is used to extract nickel sulfate solution from them. The general process of extracting nickel sulfate solution from waste batteries is as follows: first, the waste batteries are crushed and pre-treated, and then the treated waste batteries are placed in a reactor, and then nickel sulfate is extracted from them with a dissolving solution. The dissolving solution is supplemented with a catalyst or an auxiliary agent (hydrogen peroxide) during the extraction of nickel sulfate from the treated waste batteries to improve the treatment effect, and then the nickel element in the waste batteries will be dissolved and converted into nickel sulfate solution, as well as other by-products or impurities. Finally, the solution containing impurities is filtered to obtain a relatively pure nickel sulfate solution. For example: A Chinese patent with an authorization announcement number of CN217392403U discloses a reaction device for extracting nickel sulfate solution from waste batteries, including a reaction tank, a discharge pipe is fixedly installed at the lower end of the reaction tank, and a filter residue device is provided at the end of the discharge pipe on one side of the reaction tank.

[0003] The technical solution in the above patent document is to put the pretreated waste batteries into a reactor loaded with a dissolving solution when extracting nickel sulfate from waste batteries, and after the nickel sulfate solution is generated, the solution containing impurities is discharged together, and finally filtered through a filter residue device. There are at least the following defects in this treatment method: the direct introduction of waste batteries into the dissolving solution makes the nickel sulfate solution generated finally contain a large amount of impurities, and then it needs to be filtered when discharged, and the solution mixed with a large amount of impurities is not only slow when filtering, but also easy to clog the filtering structure, thereby further affecting the efficiency of nickel sulfate solution production and increasing the maintenance burden of the staff on the equipment; when the waste batteries are used in the dissolving solution to generate nickel sulfate solution, it is necessary to use a stirring structure to cooperate with a catalyst to accelerate the generation efficiency of the solution and ensure the utilization rate of the nickel element in the waste batteries, but the existing catalyst is mostly put in once, or a separate control device is used to achieve its intermittent introduction, the former is easy to cause waste of resources, and the latter will increase the production and use costs of the equipment, and if the control device fails, it is very easy to cause the failure of the solution generation in the current reactor.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 2.

[0025] 3. The separation mechanism is provided with spiral blades, and when the driving part is running, the hollow shaft is rotated through the driven gear, thereby driving the spiral blades to move, so that the waste batteries that fall into the separation mechanism can be turned over inside the separation cylinder, so as to fully contact with the dissolved liquid in the reaction tank, wherein, when the hollow shaft moves clockwise, its bottom is in a closed state, but when it moves counterclockwise, its bottom is open, so that the impurities in the separation cylinder are discharged into the collection barrel, avoiding the impurities from being mixed in the produced solution, and reducing the burden on the easy filtering treatment.

[0057] The hollow sphere 72 is connected to the hopper 71 through a liquid infusion tube, and the hollow sphere 72 is also connected to the inner cavity of the hollow shaft 48. The catalyst flowing from the hopper 71 enters the hollow sphere 72 through the liquid infusion tube, and is then transported to the inner cavity of the hollow shaft 48 through the hollow sphere 72.

[0058] An arc-shaped blocking block 74 for blocking is provided inside the cavity sphere 72. A moving rod 75 is fixedly connected to the side wall of the arc-shaped blocking block 74. One end of the moving rod 75 away from the arc-shaped blocking block 74 passes through the corresponding shell wall of the cavity sphere 72 and is provided with an end plate. A reset spring located on the moving rod 75 is sleeved between the end plate and the cavity sphere 72. By providing the reset spring, the arc-shaped blocking block 74 can achieve the effect of reset and blocking without the action of external force.

[0059] A curved rod 76 is installed on the front side of the end plate, and a pulley 77 is movably connected to the bottom end of the curved rod 76 through a pin shaft, and the pulley 77 is in active contact with the special-shaped platform 5112. The pulley 77 is in active contact with the side wall of the arc-shaped double-sided wedge in the special-shaped platform 5112, and when the pulley 77 contacts the special-shaped platform 5112, the contact position of the two moves, thereby realizing the stretching movement of the curved rod 76.

[0060] The working principle of the present invention is as follows: when the product is used, a proper amount of catalyst is first injected into the hopper 71 in the auxiliary feeding mechanism 7, and then the driving member 6 is turned on, so that the driven gear 411 in the separation mechanism 4 drives the hollow shaft 48 to move clockwise under the action of the driving member 6. When the hollow shaft 48 rotates clockwise, the spiral blade 49 and the friction disc 410 move synchronously. During the rotational movement, the friction disc 410 is in friction contact with the friction ring 46, and then the baffle 44 is rotated and adjusted under the action of the arc-shaped convex plate 45, so as to achieve the blocking of the arc-shaped gap on the fixed disc 43. When the friction disc 410 is in friction contact with the friction ring 46, it will drive the baffle 44 to rotate and adjust in the corresponding direction. When the baffle 44 is adjusted to the limit state, the blocking effect of the arc-shaped gap is completed, and thereafter, the friction disc 410 will ensure that the baffle 44 is always in the current state during the rotation process.

[0061] Finally, a proper amount of dissolving liquid is poured into the reaction tank 1, and the pre-treated used batteries are put into the reaction tank 1 through the feeding pipe. Since the separation cylinder of the separation mechanism 4 is in a closed state at this time, the dissolving liquid and used batteries entering the reaction tank 1 will not be discharged from the reaction tank 1, and the used batteries are inside the separation cylinder.

[0062] The used batteries entering the separation cylinder are turned over inside the separation cylinder under the rotation of the spiral blades 49 , and can then fully contact with the dissolving liquid inside the reaction tank 1 .

[0063] The driving gear 63 in the driving member 6 is meshed with the driven gear 411 in the separation mechanism 4, and at the same time, it drives the transmission assembly in the stirring mechanism 5 to move. The inner gear ring 53 in the transmission assembly is also meshed with the driving gear 63, thereby causing the ring 51 to rotate. The outer gear ring 52 and the auxiliary member 511 move synchronously during the movement of the ring 51. The outer gear ring 52 is meshed with the transmission gears 54 in each stirring assembly, thereby synchronously driving the tube body 55 in each stirring assembly to move.

[0064] The tube body 55 rotates to move the stirring blades 59 mounted thereon, thereby stirring the solution and further improving the contact between the solution and the waste batteries in the separation mechanism 4. When the auxiliary member 511 rotates, the lifting members 512 mounted on the top ends of the adjusting rods 56 move up and down along with the movement of the auxiliary member 511.

[0065] Each guide rod 5123 in the lifting member 512 is movably connected to the wave groove on the pipe sleeve 5111 in the auxiliary member 511. Then, as the pipe sleeve 5111 rotates, the guide rod 5123 drives the ring body 5121 in the lifting member 512 to perform reciprocating lifting motion under the action of the wave groove in cooperation with the spring telescopic rod 5122. When the ring body 5121 performs lifting motion, it simultaneously drives the corresponding adjustment rod 56 in each stirring assembly to perform synchronous lifting motion.

[0066] When the adjusting rod 56 moves up and down, it drives the arc-shaped supporting plate 57 and the fixing ring 58 to move synchronously, wherein the movement of the arc-shaped supporting plate 57 causes the dissolved liquid at the bottom of the reaction tank 1 to be turned over. When the fixing ring 58 moves up and down, the stirring blades 591 in each stirring blade member 59 rotating with the tube body 55 also move up and down under the action of the joint rod group 592, thereby improving the turning over of the dissolved liquid in the reaction tank 1 and further improving its mixing effect.

[0067] When the arc-shaped support plate 57 is lifted and lowered, it also drives the cleaning member 510 disposed thereon to move synchronously, and then the filter bodies 42 distributed on the separation cylinder in the separation mechanism 4 are cleaned by the multiple arc-shaped cleaning brushes 5102 in the cleaning member 510. This prevents the scraps of the waste motor located inside the separation cylinder from clogging the mesh of the filter body 42 due to the turning of the spiral blades 49, thereby ensuring the service life of the separation cylinder.

[0068] The sleeve 5111 rotates and synchronously drives the shaped platform 5112 to move. When the shaped platform 5112 performs circular motion, it contacts the pulley 77 in the auxiliary feeding mechanism 7. When the pulley 77 contacts the shaped platform 5112, the pulley 77 moves forward due to the extrusion force, which is transmitted to the moving rod 75 through the bent rod 76, thereby pulling the arc-shaped blocking block 74 to move. When the moving rod 75 moves, the reset spring is compressed, and the movement of the arc-shaped blocking block 74 cancels the blockage of the infusion tube, so that the catalyst in the hopper 71 enters the hollow sphere 72. The catalyst entering the hollow sphere 72 falls into the inner cavity of the hollow shaft 48 by itself under the action of gravity.

[0069] When the special-shaped platform 5112 on the pipe sleeve 5111 is separated from the contact with the pulley 77 as the pipe sleeve 5111 rotates, the moving rod 75 drives the arc-shaped blocking block 74 to reset under the action of the reset spring, thereby achieving the blocking effect again.

[0070] During the continuous rotation of the hollow shaft 48, the catalyst in its inner cavity is thrown out from the spray pipe 412 to the inside of the separation mechanism 4 under the action of gravity and centrifugal force, further accelerating the generation efficiency of the nickel sulfate solution. The intermittent feeding of the catalyst ensures the utilization rate of the catalyst and avoids waste of resources.

[0071] When the nickel sulfate solution is generated and discharged, the driving member 6 is not stopped, and the solution generated in the reaction tank 1 is directly discharged from the discharge pipe to the next process. When the solution in the reaction tank 1 is discharged to an appropriate amount, the driving member 6 is turned on to move in the reverse direction. When the driving member 6 moves in the reverse direction, the hollow shaft 48 is synchronously driven to move in the reverse direction, thereby opening the blockage of the arc-shaped gap by the baffle 44 in the portal component, and then the impurities in the separation cylinder are discharged into the integrated sleeve 3 through the arc-shaped gap with the assistance of the spiral blade 49, and discharged from the integrated sleeve 3 to the collection barrel 2 below the reaction tank 1.

[0072] After the generation and discharge of the batch of nickel sulfate solution are completed, the above steps are repeated to produce the next batch of nickel sulfate solution.

[0073] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
