Can control the reaction process of lithium waste and reaction liquid through the thickness and the scope of adjusting the isolation layer of oil baffle 31, for example at the initial treatment stage that contains lithium waste disposal, the reaction degree of lithium waste and reaction liquid is more violent, needs to increase the thickness of isolation layer 32 this moment, prevents that the gas that the reaction produced from overflowing, then can improve the thickness of isolation layer 32 through reducing the isolation scope through removing oil baffle 31. At the ending stage of lithium-containing waste treatment, the reaction degree of the lithium-containing waste and the reaction liquid is relatively mild, and the gas generated by the reaction is relatively less, so that the reaction can be accelerated by reducing the thickness of the isolation layer and enlarging the isolation range. By adjusting the oil baffle 31, it is possible to control the amount of substance to be injected into the barrier, such as: the amount of the silicon oil is reduced, and the use of isolating layer materials is saved.
In some embodiments, as shown in fig. 1, a feeding mechanism 33 is disposed in the reaction tank 30, and the feeding mechanism 33 is accommodated in the reaction solution; the feeding mechanism 33 is used for driving the processed lithium-containing waste to mix with the reaction solution and driving the processed lithium-containing waste to move directionally.
The feeding mechanism 33 is accommodated in the reaction solution and outputs power to the reaction solution, so that the processed lithium-containing waste is more sufficiently mixed with the reaction solution, the infiltration effect of the lithium-containing waste and the reaction solution is increased, the treatment effect is improved, and the treatment process is accelerated. In addition, the feeding mechanism 33 can also drive the processed lithium-containing waste to move directionally, so as to realize the centralized processing of the processed lithium-containing waste.
The processed lithium-containing waste is driven to be mixed with the reaction liquid by the feeding mechanism 33, so that the electrolyte and the reaction liquid are fully mixed, and the processed lithium-containing waste is subjected to centralized processing after being directionally moved, thereby improving the processing efficiency of the lithium-containing waste processing device 100.
In some embodiments, the feeding mechanism 33 includes a driving shaft 331 and a spiral portion 332, the driving shaft 331 is sealingly disposed through the reaction tank 30 and connected to the spiral portion 332, and the spiral portion 332 is received in the reaction tank 30.
The spiral part 332 is rotated by the driving shaft 331, and processes the lithium-containing waste in the reaction tank 30, so as to mix and move the lithium-containing waste. The driving shaft 331 is located outside the reaction tank 30 and connected to a motor to realize automatic rotation. The drive shaft 331 provides the conveying power while controlling the conveying speed.
The waste containing lithium in the reaction tank 30 is disposed by the spiral part 332, and the driving shaft 331 is sealingly inserted into the reaction tank 30 so as to be connected to the driving shaft 331 outside the reaction tank 30. The spiral part 332 outputs power to the reaction liquid so as to enable the processed lithium-containing waste to be fully infiltrated with the reaction liquid, so that the electrolyte is mixed with the reaction liquid, green processing of the electrolyte is realized, and in addition, the power can also drive the processed lithium-containing waste to move directionally so as to realize concentrated gathering and concentrated processing of the processed lithium-containing waste. The driving shaft 331 is sealingly inserted into the reaction tank 30 and connected to the spiral portion 332, so that the reaction tank 30 is prevented from leaking out along a gap with the driving shaft 331.
In some embodiments, an anti-floating net 34 is disposed in the reaction tank 30; one end of the anti-floating net 34 is fixed on one side of the notch and is disposed above the reaction solution in the reaction tank 30 for preventing the treated lithium-containing waste from overflowing.
The anti-floating net 34 floats above the reaction tank, and covers the reaction liquid to prevent the treated lithium-containing waste from overflowing. The anti-floating net 34 realizes one-way input, and the processed lithium-containing waste can not enter and is controlled below the horizontal plane. The mesh of the anti-floating net 34 may be set according to the size of the lithium-containing waste after treatment, and is generally set to 1 × 1mm, which is not limited herein.
The anti-floating net 34 can effectively prevent the treated lithium-containing waste from overflowing, so that the reaction between the lithium-containing waste and the reaction liquid is insufficient, and the pollution to the environment caused by the overflow of the lithium-containing waste can be prevented.
In some embodiments, the lithium-containing waste treatment plant further comprises an exhaust mechanism; the exhaust mechanism is provided above the reaction tank 30 and is configured to exhaust gas that overflows from the reaction solution.
Because the lithium-containing waste can generate a large amount of gas when reacting with the reaction liquid, the gas is in contact with air, and if the concentration is too high, danger can be generated, therefore, an exhaust mechanism is arranged above the reaction tank, the generated gas can be rapidly exhausted and diluted, the contact between the generated gas and the air is reduced, and the safety is improved.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict. It is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
