Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of extraction systems, and in particular to an extraction phase separation device and an extraction system. Background Art
[0002] The extraction system is an industrial equipment that uses an extractant to separate a mixture in a solution. The extraction system is widely used in the fields of lithium batteries, chemicals, biology, medicine, environment and food. In the process of lithium battery material recycling, the extraction system is also a commonly used extraction equipment. The extraction system consists of an extraction phase separation device and a storage device, and the extraction phase separation device is connected to the storage device.
[0003] In the prior art, a conventional extraction phase separation device comprises a connected device body and a stirring mechanism, wherein the device body is provided with a connected mounting hole and a processing chamber, the stirring mechanism comprises a stirring drive assembly, a stirring shaft and a stirring assembly, the power output end of the stirring drive assembly is connected to the stirring shaft so that the stirring drive assembly drives the stirring shaft to rotate, the stirring shaft is connected to the stirring assembly so that the stirring shaft drives the stirring assembly to rotate, the stirring drive assembly is located outside the processing chamber, the stirring shaft is passed through the mounting hole and is located in the processing chamber, the stirring assembly is located in the processing chamber so that the stirring shaft drives the stirring assembly to rotate for stirring and mixing the extractant and the solution, such as the Chinese patent with patent number CN201210233781.X.
[0004] However, since the existing extraction phase-separation device uses a stirring shaft to drive the stirring component to rotate to stir and mix the extractant and the solution to form a mixed liquid, during the process of the stirring component stirring the mixed liquid, the stirring component and the mixed liquid interact to generate an interaction force, that is, the stirring component applies a rotational force to the mixed liquid, and the mixed liquid applies a resistance to the stirring component. The greater the rotational force applied by the stirring component, the faster the stirring and mixing rate of the mixed liquid is, which is used to speed up the extraction processing efficiency of the extraction phase-separation device. However, the action of force is mutual. The greater the rotational force applied by the stirring component, the greater the resistance applied to the stirring component by the mixed liquid, so that the energy consumption of the stirring component for stirring the mixed liquid is relatively large. Therefore, in order to overcome the resistance generated by the mixed liquid and keep the mixed liquid at a certain stirring and mixing rate, the stirring drive component requires a large power to drive the stirring shaft to drive the stirring component to rotate, resulting in high energy consumption of the stirring mechanism, increasing the use cost of the stirring mechanism, and making the use cost of the extraction phase-separation device relatively high.

[0020] Compared with the prior art, the present invention has at least the following advantages:
[0021] 1. Since the liquid inlet is used to introduce the solution, and the agent inlet is used to introduce the extractant, the extraction chamber is connected with the liquid inlet and the agent inlet respectively, and the inner wall of the extraction chamber is provided with a guide groove which is spirally arranged from top to bottom, the liquid inlet and the agent inlet are both connected with the guide groove, and the liquid inlet and the agent inlet are both arranged along the tangent direction of the inner wall of the extraction mechanism, the solution and the extractant contact and mix with each other at the upper end of the guide groove to form a mixed liquid, and the mixed liquid spirally moves from top to bottom along the groove wall of the guide groove in the extraction chamber to complete the extraction treatment of the mixed liquid, the buffer chamber is connected with the extraction chamber and the phase separation chamber respectively, so that the mixed liquid after the extraction treatment in the extraction chamber enters the phase separation chamber along the buffer chamber, and the phase separation chamber is used to separate the mixed liquid into phases to form a light phase layer and a heavy phase layer, that is, the mixed liquid after the extraction treatment is allowed to stand and separate in the phase separation chamber, and the mixed liquid after sufficient standing is separated into a light phase layer and a heavy phase layer, thereby completing the phase separation treatment of the mixed liquid;

[0035] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:
[0036] like Figure 1 to Figure 2As shown, an extraction phase separation device 100 of an embodiment includes a device body 110, an extraction mechanism 120 and a buffer mechanism 130; the device body 110 is provided with a connecting hole 111, a phase separation chamber 112, a light phase outlet 113 and a heavy phase outlet 114, the phase separation chamber 112 is respectively connected to the connecting hole 111, the light phase outlet 113 and the heavy phase outlet 114, and the phase separation chamber 112 is used to separate the mixed liquid into a light phase layer and a heavy phase layer; the extraction mechanism 120 is penetrated by the connecting hole 111 and connected to the device body 110, and the extraction mechanism 120 is provided with a liquid inlet 121, an extraction chamber 122 and The inlet 123, the liquid inlet 121 and the inlet 123 are all arranged along the tangent direction of the inner wall of the extraction mechanism 120, the extraction chamber 122 is respectively connected with the liquid inlet 121 and the inlet 123, the inner wall of the extraction chamber 122 is provided with a guide groove 1221 spirally arranged from top to bottom, the liquid inlet 121 and the inlet 123 are both connected with the guide groove 1221; the buffer mechanism 130 is located in the phase separation chamber 112, the buffer mechanism 130 is connected with the extraction mechanism 120, the buffer mechanism 130 is provided with a buffer chamber 131, and the buffer chamber 131 is respectively connected with the extraction chamber 122 and the phase separation chamber 112.
[0037] In this embodiment, the liquid inlet 121 is used to introduce the solution, and the agent inlet 123 is used to introduce the extractant, so that the solution and the extractant are contacted and mixed with each other at the upper end of the guide groove 1221. The buffer chamber 131 is respectively connected with the extraction chamber 122 and the phase separation chamber 112, and the phase separation chamber 112 is used to separate the mixed liquid into a light phase layer and a heavy phase layer, that is, the mixed liquid after the extraction treatment is allowed to stand in the phase separation chamber 112 for stratification, and the mixed liquid after sufficient standing is divided into a light phase layer and a heavy phase layer.
[0038] In the above-mentioned extraction phase separation device 100, since the liquid inlet 121 is used to introduce the solution, the inlet 123 is used to introduce the extractant, the extraction chamber 122 is connected to the liquid inlet 121 and the inlet 123 respectively, and the inner wall of the extraction chamber 122 is provided with a guide groove 1221 arranged spirally from top to bottom, the liquid inlet 121 and the inlet 123 are both connected to the guide groove 1221, and the solution and the extractant contact and mix with each other at the upper end of the guide groove 1221 to form a mixed liquid, and the mixed liquid is in the extraction chamber 122 along the guide groove The groove wall of 1221 moves spirally from top to bottom to complete the extraction treatment of the mixed liquid. The buffer chamber 131 is connected with the extraction chamber 122 and the phase separation chamber 112 respectively, so that the mixed liquid after the extraction treatment in the extraction chamber 122 enters the phase separation chamber 112 along the buffer chamber 131. The phase separation chamber 112 is used to separate the mixed liquid into phases to form a light phase layer and a heavy phase layer, that is, the mixed liquid after the extraction treatment is allowed to stand in the phase separation chamber 112 for stratification, and the mixed liquid after sufficient standing is separated into a light phase layer and a heavy phase layer, thereby completing the phase separation treatment of the mixed liquid;
[0039] Since the solution and the extractant contact and mix with each other at the upper end of the guide groove 1221 to form a mixed liquid, the mixed liquid is affected by the combined action of gravity and the guide groove 1221 in the extraction chamber 122, so that the mixed liquid spirals from top to bottom along the groove wall of the guide groove 1221, and the solution and the extractant in the mixed liquid collide with each other and are fully mixed during the spiral movement. The mixed liquid flows to the lower end of the guide groove 1221 to be discharged, thereby completing the extraction treatment of the mixed liquid. That is to say, the extraction phase separation device 100 uses the guide groove 1221 to guide the mixed liquid to replace the method of stirring the mixed liquid by the stirring component in the prior art to complete the mixed extraction of the mixed liquid, so that the extraction phase separation device 100 does not need to be provided with a stirring mechanism, thereby solving the problem of high energy consumption when the stirring component stirs the mixed liquid in the prior art, that is, the extraction phase separation device 100 eliminates the use cost of the stirring mechanism in the prior art, so that the use cost of the extraction phase separation device 100 is relatively low.
[0040] The way in which the guide groove 1221 guides the mixed liquid relies on the gravity of the mixed liquid itself and the combined action of the spiral groove wall of the guide groove 1221 from top to bottom, so that the energy consumption of the extraction mechanism 120 for guiding the mixed liquid is relatively small. The way in which the guide groove 1221 guides the mixed liquid enables the mixed liquid to be continuously at a certain guiding mixing rate, that is, the way in which the guide groove 1221 guides the mixed liquid relies on the combined action of gravity and the spiral groove wall to enable the mixed liquid to continuously flow and collide to complete the extraction. The setting method of the guide groove 1221 of the extraction mechanism 120 is simpler than the setting method of the stirring mechanism in the prior art, which is convenient for maintenance by the staff, so that the use and maintenance cost of the extraction phase separation device 100 is relatively low.
[0041] like Figure 1 to Figure 2 As shown, in one embodiment, the cross-section of the extraction chamber 122 is a trapezoidal shape that is wide at the top and narrow at the bottom, that is, the extraction mechanism 120 is in the shape of an inverted cone, so that the flow rate of the mixed liquid in the extraction chamber 122 can be faster and faster, which is used to intensify the collision between the solution and the extractant in the mixed liquid and improve the extraction processing efficiency of the extraction mechanism 120.
[0042] like Figure 1 to Figure 2 As shown, in one embodiment, the extraction mechanism 120 is sealed and connected to the device body 110, so that the sealing performance between the extraction mechanism 120 and the device body 110 is better, thereby improving the sealing performance of the extraction and phase separation device 100.
[0043] like Figure 1 to Figure 2 As shown, in one embodiment, the cross-section of the buffer chamber 131 is a trapezoidal shape that is narrow at the top and wide at the bottom, so that the flow rate of the mixed liquid entering the buffer chamber 131 becomes slower and slower, which is used to reduce the flow rate of the mixed liquid so that the mixed liquid can stop flowing faster in the phase separation chamber 112, which is beneficial to the static stratification of the mixed liquid and improves the phase separation treatment efficiency of the extraction phase separation device 100.
[0044] like Figures 3 to 7 As shown, the present disclosure further provides an extraction system 10, comprising a solution storage tank 200, an extractant storage tank 300, a heavy phase storage tank 400, a light phase storage tank 500 and an extraction phase separation device 100 described in any of the above embodiments, wherein the solution storage tank 200, the extractant storage tank 300, the heavy phase storage tank 400, the light phase storage tank 500 and the extraction phase separation device 100 are arranged at intervals, and the solution storage tank 200 is provided with a liquid delivery pipe 210, which is passed through the liquid inlet 121 and connected to the extraction phase-separation device 100; the extractant storage tank 300 is provided with a reagent delivery pipe 310, which is arranged at the reagent inlet 123 and connected to the extraction phase-separation device 100; the heavy phase storage tank 400 is provided with a heavy phase pipe 410, which is arranged at the heavy phase outlet 114 and connected to the extraction phase-separation device 100; the light phase storage tank 500 is provided with a light phase pipe 510, which is arranged at the light phase outlet 113 and connected to the extraction phase-separation device 100.
[0045] In this embodiment, the solution storage tank 200, the extractant storage tank 300, the heavy phase storage tank 400, and the light phase storage tank 500 are all connected to the extraction phase separation device 100, so that the solution and the extractant can enter the extraction phase separation device 100 for extraction phase separation. After the mixed liquid in the extraction phase separation device 100 completes the extraction phase separation, a light phase layer and a heavy phase layer are formed, which is beneficial for the light phase layer to enter the light phase storage tank 500 and the heavy phase layer to enter the heavy phase storage tank 400, thereby facilitating the storage of the light phase layer and the heavy phase layer, so that the extraction system 10 is more convenient to use.
[0046] like Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, in one embodiment, the liquid delivery pipe 210 is provided with a liquid valve 211 and a liquid pump 212, the liquid valve 211 and the liquid pump 212 are arranged at intervals, and the liquid valve 211 and the liquid pump 212 are both used to be electrically connected to a computer. In this embodiment, the liquid valve 211 is used to open or block the liquid delivery pipe 210, so that the control convenience of the liquid delivery pipe 210 is better, thereby improving the convenience of use of the extraction system 10.

In this embodiment, the agent valve 311 is used to open or block the agent delivery pipe 310, so that the control convenience of the agent delivery pipe 310 is better, thereby improving the convenience of use of the extraction system 10.
[0048] like Figures 3 to 5 As shown, in one embodiment, the number of the liquid delivery pipe 210, the liquid valve 211, the liquid pump 212, the drug delivery pipe 310, the drug valve 311, the drug pump 312, the liquid inlet 121 and the drug inlet 123 are all two, the liquid delivery pipe 210, the liquid valve 211, the liquid pump 212 and the liquid inlet 121 are arranged in a one-to-one correspondence, and the drug delivery pipe 310, the drug valve 311, the drug pump 312 and the drug inlet 123 are arranged in a one-to-one correspondence. In this embodiment, the two liquid delivery pipes 210 are respectively the first liquid delivery pipe 210 and the second liquid delivery pipe 220, the first liquid delivery pipe 210 is provided with a first liquid valve 211 and a first liquid pump 212, the second liquid delivery pipe 220 is provided with a second liquid valve 221 and a second liquid pump 222, the two liquid inlets 121 are respectively the first liquid inlet 121 and the second liquid inlet, the first liquid delivery pipe 210 is connected to the first liquid inlet 121, the second liquid delivery pipe 220 is connected to the second liquid inlet Similarly, the two drug delivery pipes 310 are respectively the first drug delivery pipe 310 and the second drug delivery pipe 320, the first drug delivery pipe 310 is provided with a first drug valve 311 and a first drug pump 312, the second drug delivery pipe 320 is provided with a second drug valve 321 and a second drug pump 322, the two drug inlets 123 are respectively the first drug inlet 123 and the second drug inlet, the first drug delivery pipe 310 is communicated with the first drug inlet 123, and the second drug delivery pipe 320 is communicated with the second drug inlet;
[0049] Furthermore, the first liquid delivery pipe 210 and the second liquid delivery pipe 220 deliver liquid alternately, and the first agent delivery pipe 310 and the second agent delivery pipe 320 deliver extractant alternately to perform mixed extraction, so that the extraction system 10 is more convenient to use.
[0050] like Figures 3 to 6 As shown, in one embodiment, the number of the liquid delivery pipe 210, the liquid valve 211, the liquid pump 212, the drug delivery pipe 310, the drug valve 311, the drug pump 312, the liquid inlet 121 and the drug inlet 123 are all multiple, and the liquid delivery pipe 210, the liquid valve 211, the liquid pump 212 and the liquid inlet 121 are arranged in a one-to-one correspondence, and the drug delivery pipe 310, the drug valve 311, the drug pump 312 and the drug inlet 123 are arranged in a one-to-one correspondence. In this embodiment, there are three liquid delivery tubes 210, namely the first liquid delivery tube 210, the second liquid delivery tube 220 and the third liquid delivery tube 230, and there are three agent delivery tubes 310, namely the first agent delivery tube 310, the second agent delivery tube 320 and the third agent delivery tube 330.

The solution and the extractant are injected alternately, which continuously provides power for the spiral motion of the mixed liquid along the groove wall of the guide groove, so that the solution and the extractant are mixed more fully, the extraction speed is faster, and the extraction efficiency is higher, so that the extraction efficiency of the extraction system 10 is higher.
[0051] like Figures 3 to 5 As shown, in one embodiment, the liquid delivery pipe 210, the agent delivery pipe 310, the heavy phase pipe 410 and the light phase pipe 510 are all sealed and connected to the extraction phase separation device 100, so that the sealing performance of the extraction phase separation device 100 is better, thereby improving the safety of the extraction system 10.
[0052] Compared with the prior art, the present invention has at least the following advantages:
[0053] 1. Since the liquid inlet 121 is used to introduce the solution, the agent inlet 123 is used to introduce the extractant, the extraction chamber 122 is connected to the liquid inlet 121 and the agent inlet 123 respectively, and the inner wall of the extraction chamber 122 is provided with a guide groove 1221 arranged spirally from top to bottom, the liquid inlet 121 and the agent inlet 123 are both connected to the guide groove 1221, and the solution and the extractant contact and mix with each other at the upper end of the guide groove 1221 to form a mixed liquid, and the mixed liquid is in the extraction chamber 122 along the groove of the guide groove 1221. The wall moves in a spiral from top to bottom to complete the extraction treatment of the mixed liquid. The buffer chamber 131 is connected with the extraction chamber 122 and the phase separation chamber 112 respectively, so that the mixed liquid after the extraction treatment in the extraction chamber 122 enters the phase separation chamber 112 along the buffer chamber 131. The phase separation chamber 112 is used to separate the mixed liquid into a light phase layer and a heavy phase layer, that is, the mixed liquid after the extraction treatment is allowed to stand in the phase separation chamber 112 for stratification. After being fully allowed to stand, the mixed liquid is separated into a light phase layer and a heavy phase layer, thereby completing the phase separation treatment of the mixed liquid.
[0054] 2. Since the solution and the extractant contact and mix with each other at the upper end of the guide groove 1221 to form a mixed liquid, the mixed liquid is subjected to the combined action of gravity and the guide groove 1221 in the extraction chamber 122, so that the mixed liquid spirals from top to bottom along the groove wall of the guide groove 1221. The solution and the extractant in the mixed liquid collide with each other and are fully mixed during the spiral movement. The mixed liquid flows to the lower end of the guide groove 1221 to be discharged, thereby completing the extraction treatment of the mixed liquid. That is to say, the extraction phase separation device 100 uses the guide groove 1221 to guide the mixed liquid to replace the method of stirring the mixed liquid by the stirring component in the prior art to complete the mixed extraction of the mixed liquid, so that the extraction phase separation device 100 does not need to be provided with a stirring mechanism, thereby solving the problem of high energy consumption when the stirring component stirs the mixed liquid in the prior art, that is, the extraction phase separation device 100 eliminates the use cost of the stirring mechanism in the prior art, thereby making the use cost of the extraction phase separation device 100 lower.
[0055] 3. The way in which the guide groove 1221 guides the mixed liquid relies on the gravity of the mixed liquid itself and the combined effect of the spiral groove wall of the guide groove 1221 from top to bottom, so that the energy consumption of the extraction mechanism 120 for guiding the mixed liquid is relatively small. The way in which the guide groove 1221 guides the mixed liquid enables the mixed liquid to be continuously at a certain guiding mixing rate, that is, the way in which the guide groove 1221 guides the mixed liquid relies on the combined effect of gravity and the spiral groove wall to enable the mixed liquid to continuously flow and collide to complete the extraction. The setting method of the guide groove 1221 of the extraction mechanism 120 is simpler than the setting method of the stirring mechanism in the prior art, so as to facilitate maintenance by the staff, so that the use and maintenance cost of the extraction phase separation device 100 is relatively low.
[0056] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent.
