Abstract
Description
Technical Field
[0001] This utility model relates to an extraction device, and more particularly to an extraction device for cobalt sulfate solution. Background Technology
[0002] Waste batteries contain a large number of metal elements, such as lithium, nickel, cobalt, and cadmium. Extracting these metals can generate significant economic benefits, while direct discharge would cause severe environmental pollution. Therefore, recycling waste batteries is essential. Cobalt sulfate is an inorganic compound, a rose-red crystal that becomes a red powder after dehydration. It is soluble in water and methanol, slightly soluble in ethanol, and used in ceramic glazes and paint drying agents. It is also used in electroplating, alkaline batteries, and the production of cobalt-containing pigments and other cobalt products. For the main impurities Ni and Cu contained in industrial cobalt wastewater, nickel and cobalt are typically separated using AD100, P204, and P507 extractants.
[0003] However, existing cobalt sulfate extraction devices have the following shortcomings: when adding the extractant, it is usually necessary to stir the mixed solution to improve the uniformity of the extractant in the solution. However, the existing extractant mixing efficiency is not high, and most of the extractants cannot be effectively and uniformly mixed, thus consuming more time for mixing between extractants, which affects the efficiency and quality of extraction. Utility Model Content
[0004] To address the shortcomings of the aforementioned technologies, this invention provides a cobalt sulfate solution extraction device.
[0005] To solve the above technical problems, the technical solution adopted by this utility model is: a cobalt sulfate solution extraction device, including an extraction cylinder, and a transmission mechanism installed above the extraction cylinder, the transmission mechanism including:
[0006] A stirring shaft used for mixing materials, with a gear fitted at one end and stirring blades at the other end;
[0007] A gear disk fixed below the motor, which meshes with the gears;
[0008] The connecting rod has one end connected to the output shaft of the motor and the other end connected to the stirring shaft.
[0009] The omnidirectional ball is located in the center of the isolation plate, and the stirring shaft runs through the center of the omnidirectional ball.
[0010] Preferably, a mixing chamber is formed inside the extraction cylinder, and a stirring blade is placed inside the mixing chamber.
[0011] Preferably, the connecting rod includes an integrally formed horizontal part and an inclined part, with an included angle between the horizontal part and the inclined part, a connecting post formed on the horizontal part, and an insertion hole provided on the inclined part.
[0012] Preferably, the connecting column passes through the center of the gear disk and is connected to the output shaft of the motor, and the stirring shaft passes through the insertion hole and extends into the extraction cylinder.
[0013] Preferably, the gear disk is covered with a protective shell, the top of the protective shell is equipped with a motor, and the bottom is provided with an isolation plate. The center of the isolation plate is on the same vertical line as the center of the extraction cylinder.

[0015] Preferably, the outer wall of the extraction cylinder is provided with two inlets, the other ends of which extend into the mixing chamber.
[0016] This invention incorporates a transmission mechanism within the extraction cylinder. During operation, a motor drives the stirring shaft, causing the stirring blades to rotate synchronously within the extraction cylinder.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0023] Example 1
[0024] Figure 1 The cobalt sulfate solution extraction device shown includes an extraction cylinder 1, and a transmission mechanism 2 is installed above the extraction cylinder 1. By setting the transmission mechanism, the stirring shaft is driven to rotate and the stirring blades are driven to rotate, thereby achieving full mixing and stirring of the mixed solution.
[0025] During the extraction of cobalt sulfate, stirring serves several purposes:
[0026] 1) The main purpose of stirring during cobalt sulfate extraction is to promote the mass transfer process and improve extraction efficiency and effect;
[0027] 2) Promote mass transfer: Stirring can fully mix the cobalt sulfate solution with the extractant, increase the contact area and contact time between the two phases, thereby promoting the transfer of solute from one phase to another and improving extraction efficiency;
[0028] 3) Reduce mass transfer resistance: Stirring can reduce the mass transfer resistance between the two phases, making it easier for the solute to transfer from the solution to the extractant and improving the extraction effect.
[0029] As a preferred option, such as Figure 3 As shown, the transmission mechanism 2 includes:
[0030] A stirring shaft 21 is used for stirring materials. One end of the stirring shaft 21 is fitted with a gear 23, and the other end is provided with a stirring blade 25. The stirring shaft 21 is placed at an angle in the mixing chamber.
[0031] By setting up a stirring shaft, transmission is achieved through gears, and the stirring blades can be rotated, thereby achieving thorough mixing of the liquid in the mixing chamber;
[0032] Furthermore, a gear disk 24 is fixed below the motor, and the gear disk 24 meshes with the gear 23.
[0033] By fixing the gear disk below the motor, the gear connected to the stirring shaft meshes with the gear disk, thereby enabling the stirring shaft to rotate 360 degrees. This further allows the stirring blades to rotate along the inner wall of the mixing chamber while rotating on their own, thus improving the mixing effect of the extract.
[0034] Connecting rod 22, one end of which is connected to the output shaft of the motor, and the other end is connected to the stirring shaft; by setting up the connecting rod, a transmission function is achieved, specifically:
[0035] like Figure 2 As shown, the connecting rod 22 includes an integrally formed horizontal part and an inclined part, with an included angle between the horizontal part and the inclined part. A connecting post 26 is formed on the horizontal part, and an insertion hole 27 is provided on the inclined part.
[0036] The connecting rod is located below the gear disk. One end of the connecting rod is connected to the output shaft of the motor through a connecting column, and the other end is connected to the stirring shaft through an insertion hole. The motor drives the connecting column to rotate, which in turn drives the connecting rod to rotate. The rotating connecting rod drives the stirring shaft to rotate, which in turn drives the gear on the stirring shaft to move in a circular motion along the gear disk. This causes the stirring shaft to rotate in the mixing chamber while it is rotating itself, thereby driving the stirring blades to fully stir and mix the extract inside the mixing chamber.
[0037] Preferably, the connecting post 26 passes through the center of the gear disk and connects to the output shaft of the motor, while the stirring shaft 21 passes through the insertion hole 27 and extends into the extraction cylinder. The connection between the connecting post and the motor allows the motor to drive the connecting rod to rotate, which in turn drives the stirring shaft to rotate along the gear disk, thus achieving thorough mixing.
[0038] Preferably, the universal ball 3 is located at the center of the isolation plate, and the stirring shaft 21 passes through the center of the universal ball 3. By setting the universal ball, the stirring shaft can be rotated, thereby driving the stirring blades to fully stir and mix in the mixing chamber, improving the mixing effect.
[0039] The working process of the transmission mechanism is as follows: First, the solution is transported into the extraction cylinder from the two inlets. The motor is started, which drives the connecting column to rotate. The connecting column drives the stirring shaft to rotate through the connecting rod. Since the top of the stirring shaft is connected to the gear disk through a gear, when the stirring shaft rotates, it will drive the gear on it to rotate along the outer circumference of the gear disk. At the same time, since the stirring shaft is inserted with a universal ball, the stirring shaft will make a circular motion along the gear disk with the cooperation of the universal ball. At the same time, it also rotates, thereby driving the stirring blade to rotate and make a circular motion along the inner wall of the mixing chamber, which improves the mixing effect of the solution.
[0040] Preferably, the extraction cylinder 1 has a mixing chamber 8, and a stirring blade 25 is placed in the mixing chamber 8. The stirring blade thoroughly stirs and mixes the solution in the mixing chamber, thereby improving the extraction quality.
[0041] Preferably, the gear disk 24 is covered by a protective shell 4. The top of the protective shell 4 is equipped with a motor 28 and the bottom is provided with an isolation plate 41. The center of the isolation plate 41 is on the same vertical line as the center of the extraction cylinder.
[0042] By setting up an isolation plate, a supporting and positioning function is provided. In actual use, the isolation plate can be set as a detachable structure to facilitate subsequent maintenance and cleaning, while isolating the transmission mechanism from the mixing chamber.
[0043] Preferably, the extraction cylinder 1 has a heavy phase outlet 5 on one side wall and a light phase outlet 6 on the other side wall. The outer wall of the extraction cylinder 1 has two inlets 7, the other ends of which extend into the mixing chamber. The two inlets are the heavy phase inlet and the light phase inlet, respectively.
[0044] Example 2
[0045] In this embodiment, the transmission mechanism includes:
[0046] The motor has an output shaft connected to a drive shaft, which is vertically inserted into the center of a support base. The support base includes three legs formed at equal angles. Each leg has an upper gear inserted at its end, and each upper gear is connected to a lower gear via a rotating shaft. Each leg has a fixed post on its bottom surface, and a driven gear that meshes with the lower gear is fitted on the fixed post. A connecting rod is fitted on the bottom surface of the driven gear via a connecting post. Each end of the connecting rod has an insertion hole. One insertion hole is fitted onto the connecting post, and the other insertion hole contains a stirring shaft. Stirring blades are evenly distributed on the outer wall of the stirring shaft.
[0047] Preferably, a gear disk is located between the motor and the support base, and the gear disk is sleeved on the drive shaft, which meshes with the upper gears on the three legs.
[0048] Preferably, there are four stirring blades, which are symmetrically distributed in pairs.
[0049] Preferably, the other end of the drive shaft extends into the mixing chamber and is provided with a stirring rod thereon;
[0050] The specific working process is as follows: The motor is started, and the motor's output shaft drives the transmission shaft to rotate. The transmission shaft drives the stirring rod to rotate, and simultaneously, the rotation of the transmission shaft drives the gear disc to rotate. The rotation of the gear disc drives the three upper gears to rotate, the upper gears drive the lower gears to rotate, the lower gears drive the driven gear to rotate, the driven gear drives the connecting rod to rotate, and the rotation of the connecting rod drives the connected stirring shaft to rotate. The stirring shaft drives the stirring blades to rotate, thereby achieving the mixing and stirring of the solution. The transmission mechanism in this embodiment can also achieve the rotary stirring function; therefore, the rotation of the transmission mechanism is not limited to the forms of embodiments 1 and 2.
[0051] The purpose of this invention is to provide a cobalt sulfate solution extraction device. By designing a novel transmission mechanism to drive the stirring blades to rotate, the device achieves thorough mixing of the solution. Compared with the prior art, this invention has the following advantages:
[0052] 1) By setting up a transmission mechanism to drive the stirring shaft, it is possible to ensure that the extractant is evenly distributed in the solution, avoiding excessively high or low local concentrations, thereby ensuring the stability and consistency of the extraction process.
[0053] 2) By setting up a transmission mechanism to drive the stirring shaft, the mass transfer speed can be accelerated, allowing the extractant to contact the target components in the cobalt sulfate solution more quickly, thereby improving the extraction efficiency.
[0054] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
