Description

Technical Field

[0001] This invention relates to the field of separation equipment technology, and in particular to a separation equipment and production system for preparing lithium sulfide by vapor deposition. Background Technology

[0002] Lithium sulfide, as the core raw material of sulfide solid electrolyte, plays multiple key roles in all-solid-state battery technology. As a key raw material for electrolyte synthesis, lithium sulfide is the main precursor of sulfide solid electrolyte, accounting for 60%-80% of the cost of electrolyte materials. Its purity (≥99.99%) and crystallinity directly affect the ionic conductivity of the electrolyte. Furthermore, high-purity lithium sulfide can prepare electrolytes with room temperature ionic conductivity of up to 25 mS / cm, significantly improving the battery's fast charging performance (charges to 80% in 6 minutes) and energy density.

[0003] Lithium sulfide can be prepared by direct synthesis. The general process of lithium sulfide synthesis involves the direct chemical reaction of elemental lithium (Li) and elemental sulfur (S) at high temperature. Theoretically, the reaction can be classified according to the physical state of sulfur and lithium, such as gas-solid reaction, gas-liquid reaction, gas-gas reaction, solid-solid reaction, liquid-liquid reaction, and gas-liquid reaction.

[0004] Chinese patent CN117720071A discloses a method for directly synthesizing lithium sulfide powder using steam; specifically, it discloses a method for synthesizing lithium sulfide through a gas-to-gas combustion reaction, followed by a gas-solid separation process to separate the lithium sulfide and obtain the final product. This method is currently a promising approach for the direct synthesis of lithium sulfide from elemental sulfur and elemental lithium.

[0005] It should be noted that bag filters are often used to separate lithium sulfide after the gas-phase reaction, and the bags are solid bags containing metal for filtration. However, traditional bag filters directly feed the incoming air into the filter. Since there are many bags in the filter, this uneven air distribution will obviously cause individual bags to be underutilized, and also cause uneven use of multiple bags. Over time, this can easily lead to partial blockage of the bags or some bags being blocked, while others are not fully utilized, resulting in a significant decrease in the filtration efficiency of the bag filter and poor filtration effect. In addition, during the use of the bags, if the bags are damaged due to quality issues, the usage environment, or other reasons, a large amount of incoming air will be discharged directly without filtration because it is inside the bag filter, resulting in a large amount of material being wasted. Summary of the Invention

[0006] The purpose of this invention is to provide a separation apparatus and production system for preparing lithium sulfide by vapor deposition, so as to solve the problems mentioned in the background art.

[0019] Both sides of the limiting slide rod are provided with ejection grooves, and active locking rods are movably installed in both ejection grooves.

[0020] Furthermore, in a preferred embodiment of the present invention, a plurality of separation push rods are movably installed inside the bag separator box, and the plurality of separation push rods are respectively installed on the plurality of top sealing plugs.

[0021] Furthermore, in a preferred embodiment of the present invention, the detection linkage device further includes two side top frames, which are movably installed on both sides of the rotating air distribution frame, and a bottom top frame is movably installed on the bottom side of the rotating air distribution frame.

[0022] Both sides of the bottom side top frame are equipped with driving diagonal rods, and the movement of the two driving diagonal rods is used to compress the movement of the two side top frames;

[0023] A detection spring and a protective sleeve are connected between the detection top rod and the rotating air distribution frame, with the detection spring located inside the protective sleeve.

[0024] Furthermore, in a preferred embodiment of the present invention, each of the two side top frames is equipped with a linkage push rod, and each of the two linkage push rods is rotatably equipped with a linkage push shaft;

[0025] Both of the lower push frames are provided with push sliding holes, and the two linkage push shafts are respectively movably installed in the two push sliding holes.

[0027] A torsion spring is mounted on the support shaft, and the torsion spring is mounted on the inner wall of the mounting groove.

[0028] A production system for preparing lithium sulfide by vapor deposition includes the separation device described above for preparing lithium sulfide by vapor deposition.

[0029] The advantages of the separation device and production system for preparing lithium sulfide by vapor deposition proposed in this invention are:

[0030] In this invention, through the uniform air distribution device, when separating the incoming air, the air enters the air intake impact box through the air intake pipe, then enters multiple rotating air distribution frames through multiple branch air pipes, and finally is blown onto the separation bag through multiple air distribution holes. It should be noted that when the incoming air enters the air intake impact box through the air intake pipe, multiple impact blades continuously rotate, thereby driving the follower shaft to rotate. The follower shaft rotates, driving the rotating connecting rod to rotate, which in turn drives the linkage sliding shaft to rotate. This causes the linkage sliding shaft to move the telescopic swing arm, which in turn drives the telescopic rack frame to move back and forth. The telescopic rack frame's reciprocating movement drives multiple rotating gear rings to rotate, which in turn drives the drive ring to rotate, causing the drive ring to rotate the rotating air distribution frame. This results in the air being sprayed more evenly onto the separation bag, achieving uniform air distribution. Furthermore, the rotating air distribution frame drives the cleaning brush to rotate, achieving simultaneous cleaning of the separation bag during air distribution, further ensuring the filtration effect of the incoming air.

[0031] Furthermore, in this invention, by setting up a separation and sealing device, when the separation bag is damaged, the pull-down ring moves and drives the top sealing plug to move through the pull-down connecting rod, thereby achieving the purpose of automatically sealing the separation bag when it is damaged. In addition, when the top sealing plug moves, it drives the separation push rod to move down, causing the separation push rod to drive the rotating gear ring to move. The rotating gear ring moves on the drive ring through the lifting separation groove until the rotating gear ring disengages from the telescopic rack frame, thereby stopping the rotating air distribution frame from rotating and preventing further damage to the separation bag.

[0032] Furthermore, in this invention, by setting up a detection linkage device, when the air distribution frame rotates, it drives multiple detection top rods to rotate. When a certain position of the separation bag is damaged, the detection top rods are moved under the contraction force of the detection spring, achieving the purpose of active detection. At the same time, the detection top rods drive the side top frame or the bottom top frame to move. The movement of the side top frame drives the linkage push rod to move, or the movement of the bottom top frame drives the two drive inclined rods to move, so that the two drive inclined rods squeeze the two side top frames to move, which can also drive the two linkage push rods to move. The movement of the linkage push rods drives the linkage push shaft to move, so that the linkage push shaft drives the lower push frame to rotate. At the same time, the linkage push shaft slides in the push sliding hole, and the rotation of the lower push frame drives the support rotating shaft to rotate in the mounting groove, and causes the mounting torsion spring to be stressed. The rotation of the lower push frame drives the lower pull ring to move. The movement of the lower pull ring drives the top sealing plug to move through the lower pull connecting rod, and causes the upper push spring to be stressed, thereby achieving the purpose of automatically sealing the separation bag when it is damaged.

[0055] Please refer to the attached instruction manual. Figures 2-15 The present invention provides a separation device for preparing lithium sulfide by vapor deposition, which includes a bag separator box 1, a plurality of separation bags 2 are provided in the bag separator box 1, and an air inlet pipe 3 and an exhaust pipe 4 are respectively installed on both sides of the bag separator box 1, and an ash discharge pipe 5 is installed on the bottom side of the bag separator box 1.

[0056] Further, please refer to the appendix to the instruction manual. Figures 4-8The present invention provides a separation device for preparing lithium sulfide by vapor deposition, which further includes a uniform gas distribution device 6. The uniform gas distribution device 6 is installed in a bag separator box 1, which is used to uniformly spray the incoming gas onto multiple separation bags 2. Specifically, the uniform gas distribution device 6 includes multiple rotating gas distribution frames 601. Multiple drive rings 608 are rotatably mounted on the bag separator box 1. The multiple rotating gas distribution frames 601 are respectively mounted on the multiple drive rings 608, and the multiple separation bags 2 are respectively located in the multiple rotating gas distribution frames 601. Multiple gas distribution holes 602 are opened on the rotating gas distribution frames 601, and cleaning brushes 603 are installed on the rotating gas distribution frames 601. It should be noted that, in this embodiment of the invention, when separating the intake air, the rotating air distribution frame 601 rotates, thereby spraying the intake air more evenly onto the separation bag 2, achieving the purpose of uniform air distribution; at the same time, the rotation of the rotating air distribution frame 601 drives the cleaning brush 603 to rotate, achieving the purpose of synchronous cleaning of the separation bag 2 during air distribution, further ensuring the filtration effect of the intake air; in addition, when the top sealing plug 701 moves, it drives the separation push rod 706 to move downward, causing the separation push rod 706 to drive the rotating gear ring 609 to move. The rotating gear ring 609 moves on the drive ring 608 through the lifting separation groove 610 until the rotating gear ring 609 disengages from the telescopic rack frame 611, thereby causing the rotating air distribution frame 601 to stop rotating.

[0057] More specifically, in this embodiment of the invention, a plurality of separation and sealing devices 7 are also included. These devices 7 are all installed inside the bag separator box 1. The separation and sealing devices 7 are used to separate the uniform air distribution device 6 and seal the separation bag 2. Each separation and sealing device 7 includes a top sealing plug 701, which is movably installed inside the bag separator box 1 and is used to seal the separation bag 2. It should be noted that in this embodiment of the invention, when the separation bag 2 is damaged, the pull-down linkage 805 causes the top sealing plug 701 to move, and the push spring 806 is subjected to force, thereby achieving the purpose of automatically sealing the separation bag 2 when it is damaged.

[0058] More specifically, in this embodiment of the invention, multiple detection linkage devices 8 are also included. The multiple detection linkage devices 8 are all installed inside the bag separator box 1. The detection linkage devices 8 are used to detect the separated bag 2 and trigger the separation sealing device 7. The detection linkage device 8 includes multiple detection top rods 801, which are movably installed on the rotating air distribution frame 601. Multiple pull-down connecting rods 805 are movably installed on the bag separator box 1. The pull-down connecting rods 805 are installed on the top sealing plug 701. A pull-down ring 804 is installed on the bottom side of the pull-down connecting rod 805. Two push-down frames 810 are rotatably installed on the rotating air distribution frame 601. An upward push spring 806 is installed between the top sealing plug 701 and the bag separator box 1. It should be noted that in this embodiment of the invention, when the air distribution frame 601 is rotated, it drives multiple detection top rods 801 to rotate. When a certain position of the separation bag 2 is damaged, the detection top rod 801 is moved under the contraction force of the detection spring 802, which in turn drives the top sealing plug 701 to move, thereby realizing the active sealing of the damaged separation bag 2.

[0059] Please continue to refer to the instruction manual appendix. Figures 4-8 Furthermore, the separation device for preparing lithium sulfide by vapor deposition provided in this embodiment of the invention includes a uniform gas distribution device 6, which further includes an inlet impact box 604. The inlet impact box 604 is installed in the bag separator box 1, and the inlet pipe 3 extends into the inlet impact box 604.

[0060] In addition, multiple branch air pipes 607 are installed on the air intake impact box 604, and multiple rotating air distribution frames 601 are rotatably installed on the multiple branch air pipes 607 respectively. It should be noted that, in this embodiment of the invention, when separating the intake air, the intake air enters the air intake impact box 604 through the intake pipe 3, then enters the multiple rotating air distribution frames 601 through the multiple branch air pipes 607, and then blows onto the separation bag 2 through the multiple air distribution holes 602; when the intake air enters the air intake impact box 604 through the intake pipe 3, it impacts the multiple impact blades 606 to rotate continuously, thereby achieving the purpose of driving the telescopic rack frame 611 to move.

[0061] More specifically, in this embodiment of the invention, a follower shaft 605 is rotatably mounted on the intake impact box 604, and a plurality of impact blades 606 are circumferentially and equidistantly mounted on the follower shaft 605.

[0062] In addition, rotating gear rings 609 are slidably mounted on multiple drive rings 608, a telescopic rack frame 611 is slidably mounted inside the bag separator box 1, a telescopic swing rod 613 is mounted on the telescopic rack frame 611, a rotating connecting rod 612 is mounted on one end of the follower shaft 605, a linkage sliding shaft 614 is rotatably mounted on one side of the rotating connecting rod 612, and the linkage sliding shaft 614 is movably mounted inside the telescopic swing rod 613. It should be noted that, in this embodiment of the invention, when the follower shaft 605 rotates, it drives the rotating connecting rod 612 to rotate. The rotation of the rotating connecting rod 612 drives the linkage sliding shaft 614 to rotate, which in turn drives the telescopic swing rod 613 to move. The linkage sliding shaft 614 slides within the telescopic swing rod 613. Simultaneously, when the rotating connecting rod 612 rotates one revolution, the telescopic swing rod 613 reciprocates laterally once, causing the telescopic swing rod 613 to drive the telescopic rack frame 611 to move back and forth. The reciprocating movement of the telescopic rack frame 611 drives multiple rotating gear rings 609 to rotate. The rotation of the rotating gear rings 609 drives the drive ring 608 to rotate, thereby causing the drive ring 608 to drive the rotating air distribution frame 601 to rotate, achieving the purpose of uniform air distribution.

[0063] More specifically, in this embodiment of the invention, a lifting and separating groove 610 is provided on the rotating gear ring 609, and a drive ring 608 is slidably installed in the lifting and separating groove 610; a support spring 615 is installed on the inner wall of the lifting and separating groove 610, and the support spring 615 is installed on the drive ring 608. It should be noted that, in this embodiment of the invention, when the top sealing plug 701 moves, it drives the separating push rod 706 to move downward, so that the separating push rod 706 drives the rotating gear ring 609 to move. The rotating gear ring 609 moves on the drive ring 608 through the lifting and separating groove 610, and causes the support spring 615 to be stressed, until the rotating gear ring 609 disengages from the telescopic rack frame 611, thereby causing the rotating air distribution frame 601 to stop rotating.

[0064] Please refer to the instruction manual attached. Figure 4 and Figures 9-12 Furthermore, the separation device for preparing lithium sulfide by vapor deposition provided in the embodiment of the present invention includes a separation sealing device 7 that further includes a plurality of limiting slide rods 702, all of which are installed in the bag separator box 1, and a plurality of top sealing plugs 701 are respectively movably installed on the plurality of limiting slide rods 702.

[0065] In addition, ejection grooves 704 are provided on both sides of the limiting slide bar 702, and active locking rods 703 are movably installed in both ejection grooves 704. Two active locking slots 707 are provided in the top sealing plug 701, and the two active locking rods 703 are respectively set to correspond to the two active locking slots 707. An ejection spring 705 is installed on the inner wall of the ejection groove 704, and the ejection spring 705 is installed on the active locking rod 703. It should be noted that, in this embodiment of the invention, when the top sealing plug 701 moves downward, it moves on the limiting slide bar 702, causing the top sealing plug 701 to press the two active locking rods 703 to move. The active locking rods 703 retract into the ejection slide groove 704, and the ejection spring 705 is subjected to force until the active locking rods 703 correspond to the active locking groove 707. This causes the ejection spring 705 to push the active locking rods 703 to lock in the active locking groove 707, thereby locking the top sealing plug 701 and ensuring the sealing effect of the top sealing plug 701.

[0066] More specifically, in this embodiment of the invention, a plurality of separation push rods 706 are movably installed inside the bag separator box 1, and the plurality of separation push rods 706 are respectively mounted on a plurality of top sealing plugs 701. It should be noted that, in this embodiment of the invention, when the top sealing plugs 701 move, they drive the separation push rods 706 to move, which in turn drives the rotating gear ring 609 to move, thereby causing the rotating gear ring 609 to disengage from the telescopic rack frame 611, achieving the purpose of stopping the rotation of the rotating air distribution frame 601.

[0067] Please refer to the instruction manual attached. Figure 4 , Figure 11 and Figures 13-15 Furthermore, the separation device for preparing lithium sulfide by vapor deposition provided in this embodiment of the invention includes a detection linkage device 8 that further includes two side top frames 807. The two side top frames 807 are movably installed on both sides of the rotating gas distribution frame 601, and a bottom top frame 808 is movably installed on the bottom side of the rotating gas distribution frame 601. Both sides of the bottom top frame 808 are equipped with driving inclined rods 809, and the movement of the two driving inclined rods 809 is used to compress the movement of the two side top frames 807.

[0068] Furthermore, a detection spring 802 and a protective sleeve 803 are connected between the detection top rod 801 and the rotating air distribution frame 601, with the detection spring 802 located inside the protective sleeve 803. It should be noted that in this embodiment of the invention, when a break occurs at a certain position in the separation bag 2, the contraction force of the detection spring 802 causes the detection top rod 801 to move, thereby causing the detection top rod 801 to move either the side top frame 807 or the bottom top frame 808. The movement of the side top frame 807 causes the linkage push rod 812 to move, or the movement of the bottom top frame 808 causes the two driving inclined rods 809 to move, causing the two driving inclined rods 809 to press against the two side top frames 807, which in turn causes the two linkage push rods 812 to move, thus achieving the purpose of sealing the separation bag 2 through the top sealing plug 701.

[0069] More specifically, in this embodiment of the invention, each of the two side top frames 807 is equipped with a linkage push rod 812, and each of the two linkage push rods 812 is rotatably mounted with a linkage push shaft 813; each of the two lower push frames 810 is provided with a push sliding hole 811, and the two linkage push shafts 813 are respectively movably installed in the two push sliding holes 811. It should be noted that, in this embodiment of the invention, when the two side top frames 807 move, they drive the two linkage push rods 812 to move, and the movement of the linkage push rods 812 drives the linkage push shafts 813 to move, so that the linkage push shafts 813 drive the lower push frames 810 to rotate. At the same time, the linkage push shafts 813 slide in the push sliding holes 811, and the rotation of the lower push frames 810 drives the pull ring 804 to move. The movement of the pull ring 804 drives the top sealing plug 701 to move through the pull connecting rod 805, and causes the upper push spring 806 to be stressed, thereby achieving the purpose of automatically sealing the separation bag 2 when it is damaged.

[0070] Please continue to refer to the instruction manual appendix. Figure 4 , Figure 11 and Figures 13-15 More specifically, in this embodiment of the invention, two mounting slots 815 are provided on one side of the rotating air distribution frame 601. A support shaft 814 is rotatably mounted in each of the two mounting slots 815, and two lower push frames 810 are respectively mounted on the two support shafts 814. A torsion spring 816 is mounted on the support shaft 814, and the torsion spring 816 is mounted on the inner wall of the mounting slot 815. It should be noted that in this embodiment of the invention, when the lower push frame 810 rotates, the support shaft 814 rotates within the mounting slot 815, causing the torsion spring 816 to be stressed. The rebound force of the torsion spring 816 helps the lower push frame 810 to reset.

[0071] Additionally, please refer to the instruction manual appendix. Figure 1The present invention also provides a production system for preparing lithium sulfide by vapor deposition, the production system including the separation device for preparing lithium sulfide by vapor deposition as described in the above embodiment of the present invention, the separation device being the device corresponding to the gas-solid separation process in the production system for preparing lithium sulfide by vapor deposition according to the present invention.

[0072] In summary, the working principle of the separation device for preparing lithium sulfide by vapor deposition provided in this embodiment of the invention is as follows:

[0073] When separating the intake air, the intake air enters the intake impact box 604 through the intake pipe 3, then enters the multiple rotating air distribution frame 601 through multiple branch air pipes 607, and then blows onto the separation bag 2 through multiple air distribution holes 602. Specifically, when the intake air enters the intake impact box 604 through the intake pipe 3, multiple impact blades 606 continuously rotate, thereby driving the follower shaft 605 to rotate. The rotation of the follower shaft 605 drives the rotating connecting rod 612 to rotate, and the rotation of the rotating connecting rod 612 drives the linkage sliding shaft 614 to rotate, causing the linkage sliding shaft 614 to move the telescopic swing rod 613. The linkage sliding shaft 614 slides inside the telescopic swing rod 613. At the same time, when the rotating connecting rod 612 rotates one revolution, the telescopic swing rod 613 reciprocates laterally once, thereby causing the telescopic swing rod 613 to drive the telescopic rack frame 611 to move back and forth. The reciprocating movement of the telescopic rack frame 611 drives multiple rotating gear rings 609 to rotate, and the rotation of the rotating gear rings 609 drives the drive ring 608 to rotate, causing the drive ring 608 to drive the rotating air distribution frame 601 to rotate, thereby spraying the intake air more evenly onto the separation bag 2, achieving the purpose of uniform air distribution.

[0074] Furthermore, rotating the air distribution frame 601 drives the cleaning brush 603 to rotate, achieving the purpose of simultaneously cleaning the separation bag 2 during air distribution, further ensuring the filtration effect of the incoming air; in addition, when the air distribution frame 601 rotates, it drives multiple detection rods 801 to rotate. Therefore, when a certain position of the separation bag 2 is damaged, the detection rod 801 is moved under the contraction force of the detection spring 802, which in turn causes the detection rod 801 to drive the side top frame 807 or the bottom top frame 808 to move. It should be noted that the movement of the side top frame 807 drives the linkage push rod 812 to move, or the movement of the bottom top frame 808 drives the two drive inclined rods 809 to move, so that the two drive inclined rods 809 press the two side top frames 807 to move, which can also drive the two linkage push rods 812 to move. The movement of the linkage push rods 812 drives the linkage push shaft 813 to move, so that the linkage push shaft 813 drives the lower push frame 810 to rotate. The linkage push shaft 813 slides in the push sliding hole 811, and the rotation of the lower push frame 810 drives the support rotating shaft 814 to rotate in the mounting groove 815, and causes the mounting torsion spring 816 to be stressed. The rotation of the lower push frame 810 drives the pull ring 804 to move. The movement of the pull ring 804 drives the top sealing plug 701 to move through the pull connecting rod 805, and causes the upper push spring 806 to be stressed, thereby achieving the purpose of automatically sealing the separation bag 2 when it is damaged.

[0075] Furthermore, when the top sealing plug 701 moves, it drives the separation push rod 706 to move downward, causing the separation push rod 706 to drive the rotating gear ring 609 to move. The rotating gear ring 609 moves on the drive ring 608 through the lifting separation groove 610 until the rotating gear ring 609 disengages from the telescopic rack frame 611, thereby causing the rotating air distribution frame 601 to stop rotating.

[0076] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
