Description

Technical Field

[0001] This utility model relates to the field of solid-state battery waste liquid treatment technology, and specifically to a solid-state battery waste liquid discharge system. Background Technology

[0002] Solid-state batteries generate a large amount of waste liquid during processes such as cathode material preparation, solid electrolyte processing, coating and film formation, and equipment cleaning. This type of waste liquid has typical characteristics of being a "solid-gel-liquid mixture," containing not only unreacted or residual solid electrolyte particles, fine powder of positive and negative electrode active materials, and inorganic salt deposits, but also colloidal flocs formed by binders and polymer residues. It also contains process rinsing fluids, solvent condensate, and a small amount of equipment wear particles. Because these solid particles and colloidal substances have a large particle size range, small density differences, and are prone to both agglomeration and redispersibility, the solid-liquid separation process of solid-state battery waste liquid is more complex than that of traditional lithium-ion battery waste liquid.

[0003] In existing technologies, simple sedimentation tanks, filters, or plate and frame filter presses are commonly used to treat waste liquid. For example, a battery wastewater treatment filter press mechanism disclosed in patent application number CN202422426376.0 uses various filtration devices such as filter screens and sponge pads to treat waste liquid; another example is a filtration device for recovering waste liquid from capacitor production disclosed in patent application number CN202010216637.X, which also uses gravity sedimentation and filtration to separate sludge and liquid. However, solid-state battery waste liquid does not only contain solid particulate sludge and liquid wastewater, but also a colloidal agglomerate between the two. This agglomerate generally comes from adhesives, colloids, and other suspended substances left over from battery experiments or cleaning. After mutual coagulation and agglomeration, it forms a colloidal agglomerate. This colloidal agglomerate is not easy to settle naturally, is difficult to be intercepted by ordinary filter screens, and is very easy to clog filter cloths; some of the colloidal agglomerate will break down again under shearing action and be discharged with the liquid phase, causing frequent blockage of the downstream membrane treatment system or discharge pipeline. In addition, existing sedimentation tanks and filtration devices generally require manual operation for regular opening, removal of sediment, or cleaning of filter screens. This is not only labor-intensive, but also poses a safety hazard as workers are likely to come into direct contact with waste liquids containing lithium residues or solvent residues.

[0004] Therefore, existing solid-state battery waste liquid treatment systems still have significant shortcomings in terms of solid-liquid separation efficiency, gel control capability, continuous operation capability, and avoidance of human contact. There is an urgent need for a waste liquid discharge treatment device with a more reasonable structure that can perform graded and continuous treatment of solid particles, gels and liquids, and reduce the risk of human contact. Utility Model Content

[0005] The technical problem to be solved by this utility model is that solid-state battery waste liquid contains a lot of impurities, which leads to high labor intensity in separation during centralized water treatment and easy clogging of filtration equipment. The purpose is to provide a solid-state battery waste liquid discharge system that can pre-treat and separate impurities in solid-state battery waste liquid in the early stage, reduce the energy consumption and filtration intensity of the later treatment equipment, and improve the quality and efficiency of waste liquid treatment and separation.

[0006] This utility model is achieved through the following technical solution:

[0007] A solid-state battery waste liquid discharge system includes a wastewater tank and further includes:

[0008] The discharge chamber is connected to the top of the sewage tank. The bottom of the discharge chamber is provided with several water distribution holes. A diversion plate is provided at the bottom of the water distribution holes. Several filter tanks are provided below the diversion plate.

[0009] The filter chamber is located below the discharge chamber. The bottom surface of the filter tank has several perforations. The filter tank and the inner wall of the filter chamber are connected, and adjacent filter tanks are connected to each other.

[0010] A feeding mechanism is disposed in the filter chamber and located above the filter tank;

[0011] The diversion plate has at least one inclined surface, the filter tank is located below the inclined surface of the diversion plate, and the pushing mechanism is used to push the material on the filter tank into the filter chamber during the reciprocating motion.

[0012] In the above technical solution, wastewater flows from the discharge chamber into the filter tank of the filtration chamber. The pusher mechanism is activated to squeeze and push the gel-like material in the filter tank. During the pushing process, the gel-like material will break due to the squeezing action. The broken gel-like material has a smaller volume and can squeeze out the water it contains. The water squeezed out by the broken gel-like material will also flow along the leakage hole to the collection tank, thus achieving the initial separation of waste liquid.

[0013] Furthermore, a collection tank is connected to the filter chamber, and a discharge pipe that penetrates the side wall of the filter chamber is connected to the collection tank. There is a gap between the bottom surface of the collection tank and the bottom surface of the filter chamber.

[0014] In the above technical solution, the collection tank is used to collect the discharged wastewater and the wastewater separated from the crushed colloidal material.

[0015] Furthermore, the filter tank includes an upwardly positioned inlet and baffles located on both sides of the inlet, and the pushing mechanism includes a driving component and a pushing part. The driving component includes a fixed end connected to the filter chamber and a movable end connected to the pushing part.

[0016] In the above technical solution, the driving component can drive the extrusion part to reciprocate along the filter groove to further break up the gel-like material.

[0017] Furthermore, the surfaces of the baffles facing each other form several protruding ridges.

[0018] In the above technical solution, the pushing mechanism scrapes the protruding edges when pushing the gel-like material, which can break the gel-like material faster and more effectively.

[0019] Furthermore, the filter tank is rotatably connected to a partition on the side away from the pushing mechanism along its length, and the maximum stroke distance of the driving component is greater than the length of the filter tank.

[0020] In the above technical solution, the baffle is used to prevent the gel-like material from falling. After the feeding mechanism has reciprocated for several strokes, the baffle can be pushed open to push the broken gel-like material to the bottom of the filter chamber.

[0021] Furthermore, a through groove is provided in the middle of both baffles, and a pressing block is rotatably connected in the through groove. A connecting rod is fixedly connected to the bottom of the pressing block, and a pressure plate is fixedly connected to the end of the connecting rod. A through hole is provided at the bottom of the filter tank for the pressure plate to pass through.

[0022] In the above technical solution, when the extrusion block is squeezed by the extrusion pusher, the extrusion blocks on both sides will converge towards the center of the filter tank, and beat and crush the gel-like material.

[0023] Furthermore, the pressure plate is inclined toward the pushing mechanism, and the bottom surface of the pressure plate is close to the pushing mechanism.

[0024] In the above technical solution, the inclined pressure plate can be pressed down more effectively by the pushing mechanism, avoiding stroke jamming.

[0025] Furthermore, the width of the extrusion block gradually increases along the length of the filter tank on the side away from the pushing mechanism. Several protrusions are connected to the faces of the two extrusion blocks facing each other. After the two extrusion blocks rotate relative to each other to the maximum angle, they form an extrusion channel with the filter tank. The length of the extrusion push part is greater than the length of the extrusion channel. The extrusion push part has the same shape as the extrusion channel. The minimum longitudinal cross-sectional area of ​​the extrusion push part is smaller than the minimum longitudinal cross-sectional area of ​​the extrusion channel.

[0026] In the above technical solution, the thickness of the extrusion block varies, which can further crush the gel-like material entering the extrusion channel.

[0027] Furthermore, the bottom surface of the filter chamber slopes downwards on the side away from the feeding mechanism, and the length of the filter tank is greater than the length of the liquid collection tank.

[0028] In the above technical solution, the bottom of the filter chamber is inclined, which can concentrate the gel-like material falling from both sides of the filter tank at the lowest point, making it easy to collect.

[0029] Furthermore, the wastewater tank has several sedimentation tanks extending downwards, the bottom of the filtration chamber is connected to a drying chamber, and a filter press is connected to the side of the drying chamber away from the filtration chamber.

[0030] In the above technical solution, after the gelatinous material is collected to a certain quantity, it is discharged into the drying chamber, where the broken gelatinous material and large-particle impurities are dried and dehydrated. After drying, it is discharged into the filter press, where the dried impurities are compressed into cake-shaped or block-shaped structures that are easy to store and collect, for further impurity treatment in the later stage.

[0031] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0032] In this invention, after the gel-like material and large-particle impurities fall onto the filter tank, the driving component is activated to control the extrusion pusher to move. The bottom surface of the extrusion pusher contacts the inner bottom surface of the filter tank. When passing the inclined pressure plate, the extrusion pusher pushes the pressure plate, and the pressure plate presses down. The extrusion blocks on both sides of the baffle converge toward the center of the filter tank, forming an extrusion channel. After the gel-like material is pushed into the extrusion channel by the extrusion pusher, it gradually breaks down due to the narrowing of the inner diameter of the extrusion channel. At the same time, when passing through the baffle and extrusion blocks, it is pierced by the protrusions and thorns, further breaking down the gel-like material, thereby reducing its volume. It can also extract the water contained in the gel-like material, reducing its volume. Finally, the driving component controls the extrusion pusher to push open the partition, and the partition rotates downward to open the filter tank. The broken gel-like material on the filter tank falls into the filter chamber for collection, realizing the separation from the liquid wastewater. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are for explaining the utility model only and are not intended to limit the utility model. It should be noted that this utility model is already in the actual research and development stage.

[0044] Example 1:

[0045] like Figures 1 to 4 As shown, this embodiment provides a solid-state battery waste liquid discharge system, including a wastewater tank, and further comprising:

[0046] Discharge chamber 1, the top of discharge chamber 1 is connected to sewage tank, and several water distribution holes 11 are opened at the bottom of discharge chamber 1. A diversion plate 12 is provided at the bottom of the water distribution holes 11, and several filter tanks 3 are provided below the diversion plate 12.

[0047] Filter chamber 2 is located below discharge chamber 1. The bottom surface of filter tank 3 is provided with several leakage holes 33. Filter tank 3 is connected to the inner wall of filter chamber 2, and adjacent filter tanks 3 are connected to each other.

[0048] The material pushing mechanism is installed inside the filter chamber 2 and located above the filter tank 3;

[0049] The flow divider 12 has at least one inclined surface, the filter tank 3 is located below the inclined surface of the flow divider 12, and the pushing mechanism is used to push the material on the filter tank 3 into the filter chamber 2 during the reciprocating motion.

[0050] like Figures 2 to 4 As shown, a collection tank 21 is connected inside the filter chamber 2, and a discharge pipe that penetrates the side wall of the filter chamber 2 is connected to the collection tank 21. There is a gap between the bottom surface of the collection tank 21 and the bottom surface of the filter chamber 2.

[0051] like Figures 2 to 6As shown, the feeding mechanism includes a driving member 41 and an extrusion part 42. The driving member 41 includes a fixed end connected to the filter chamber 2 and a movable end connected to the extrusion part 42.

[0052] like Figure 6 As shown, the surfaces of the baffles 31 facing each other form several protruding ridges 34.

[0053] Specifically, after solid-state batteries are tested or cleaned in the laboratory, the waste liquid and wastewater generated will be discharged into the sewage tank through indoor pipes for temporary storage, which will facilitate subsequent centralized sewage treatment. After a certain period of sedimentation, the waste liquid flowing into the sewage tank will enter the discharge chamber 1 through the sewage pipe. The water distribution hole 11 at the bottom of the discharge chamber 1 is equipped with a valve that can control the opening and closing of the water distribution hole 11. After the discharge chamber 1 contains a certain amount of waste liquid, the valve is opened and the sewage tank should stop discharging. The waste liquid flows out along the water distribution hole 11 and flows to the diversion plate 12.

[0054] The diversion plate 12 is fixedly connected inside the discharge chamber 1. The diversion plate 12 is V-shaped and has two inclined surfaces. The waste liquid flowing from the diversion hole 11 onto the diversion plate 12 falls down through the inclined surfaces of the diversion plate 12 and flows into the filter tank 3 below with the guidance of the inclined surfaces. The filter tank 3 is provided with several leakage holes 33. In the waste liquid falling through the diversion plate 12, the liquid phase wastewater and small-diameter solid phase impurities fall into the collection tank 21 at the bottom of the discharge chamber 1 through the leakage holes 33, while the coagulated gel and some larger-diameter solid phase impurities remain in the filter tank 3, realizing the initial separation of the liquid phase and intercepting the gel and large-diameter impurities in the solid battery waste liquid.

[0055] After the waste liquid in the discharge chamber 1 is discharged, the valve at the water distribution hole 11 is closed, and the sewage tank continues to discharge waste liquid into the discharge chamber 1 to cycle the next treatment process. After the discharge chamber 1 stops discharging, the pushing mechanism is started, the drive component 41 is started, and the extrusion part 42 is pushed to move along the filter tank 3, squeezing and pushing the gel-like material in the filter tank 3. During the process of being pushed, the gel-like material is broken by the protrusion 34 on the baffle 31 of the filter tank 3 and the squeezing action of the extrusion part 42. The volume of the broken gel-like material becomes smaller and it can squeeze out the water it contains. The water squeezed out by the broken gel-like material will also flow along the leakage hole 33 to the collection tank 21.

[0056] Example 2:

[0057] like Figures 2 to 6 As shown, the filter tank 3 includes an upward-facing inlet and baffles 31 located on both sides of the inlet.

[0058] like Figure 6 As shown, the filter tank 3 is rotatably connected to the partition plate 32 on the side away from the pusher mechanism along the length direction, and the maximum stroke distance of the drive component 41 is greater than the length of the filter tank 3.

[0059] like Figures 2 to 7 As shown, both baffles 31 have through slots in the middle, and extrusion blocks 5 are rotatably connected in the through slots. A connecting rod 51 is fixedly connected to the bottom of the extrusion block 5, and a pressure plate 52 is fixedly connected to the end of the connecting rod 51. A through hole 35 is provided at the bottom of the filter tank 3 for the pressure plate 52 to pass through.

[0060] like Figure 5 and Figure 7 As shown, the pressure plate 52 is inclined toward the pushing mechanism, and the bottom surface of the pressure plate 52 is close to the pushing mechanism.

[0061] like Figure 5 and Figure 7 As shown, the width of the extrusion block 5 gradually increases along the length of the filter tank 3 on the side away from the pushing mechanism. Several protrusions 53 are connected to the faces of the two extrusion blocks 5 facing each other. After the two extrusion blocks 5 rotate relative to each other to the maximum angle, they form an extrusion channel with the filter tank 3. The length of the extrusion push part 42 is greater than the length of the extrusion channel. The extrusion push part 42 has the same shape as the extrusion channel. The minimum longitudinal cross-sectional area of ​​the extrusion push part 42 is smaller than the minimum longitudinal cross-sectional area of ​​the extrusion channel.

[0062] like Figure 2 As shown, the length of the filter tank 3 is greater than the length of the collection tank 21.

[0063] Specifically, the filter tank 3 includes an upwardly oriented inlet and baffles 31 located on both sides of the inlet. The longitudinal cross-sectional shape of the filter tank 3 can be V-shaped, U-shaped, trapezoidal, annular, etc. The baffles 31 on both sides of the inlet are symmetrically arranged. A through groove is opened in the middle of the baffle 31. An extrusion block 5 is rotatably connected in the through groove. The thickness of the extrusion block 5 is much greater than the thickness of the baffle 31. The surfaces of the extrusion blocks 5 facing each other on the two baffles 31 are planes. The thickness of the extrusion block 5 gradually increases along the length of the filter tank 3. The thickness of the extrusion block 5 on the side closer to the partition 32 is greater than the thickness on the side closer to the pushing mechanism.

[0064] The bottom of the filter tank 3 has a through hole 35. The bottom of the extrusion block 5 is fixedly connected to a connecting rod 51. The side of the connecting rod 51 away from the extrusion block 5 is fixedly connected to a pressure plate 52. The pressure plate 52 is inclined and faces the pushing mechanism. When the pressure plate 52 moves downward along the through hole 35, the extrusion block 5 rotates toward the center of the filter tank 3. After the two extrusion blocks 5 move toward the center, they together with the filter tank 3 form an extrusion channel. Because the thickness of the extrusion blocks 5 is different, the opening of the extrusion channel is wider on the side closer to the pushing mechanism and narrower on the side closer to the partition plate 32.

[0065] Regarding the extrusion process of the gel-like material: After the gel-like material and large-particle impurities fall onto the filter tank 3, the drive unit 41 is activated to control the movement of the extrusion pusher 42. The bottom surface of the extrusion pusher 42 contacts the inner bottom surface of the filter tank 3. When passing the inclined pressure plate 52, the extrusion pusher 42 pushes the pressure plate 52, and the pressure plate 52 presses down. The extrusion blocks 5 on both sides of the baffle 31 converge toward the center of the filter tank 3, forming an extrusion channel. After the gel-like material is pushed into the extrusion channel by the extrusion pusher 42, it gradually breaks due to the narrowing of the inner diameter of the extrusion channel. At the same time, when passing through the baffle 31 and the extrusion blocks 5, it is hit by the protrusions 34 and spikes 5. 3. The process further breaks down the gelatinous substance, thereby reducing its volume and allowing the water contained within it to be extracted. After the initial formation of the drive member 41, the extrusion part 42 is not allowed to pass over the partition 32. Instead, the drive member 41 causes the extrusion part 42 to reciprocate on the filter tank 3, causing the gelatinous substance to rub against the extrusion block 5 and the baffle 31, further breaking it down. Preferably, after the extrusion part 42 returns and leaves the pressure plate 52, the extrusion block 5 expands outward, and when it moves forward, the extrusion block 5 retracts again, achieving the effect of beating the gelatinous substance. The protrusion 53 can better break down the gelatinous substance.

[0066] After the drive unit 41 reciprocates multiple times, the volume of the gel-like substance is significantly reduced, but it cannot fall through the leakage hole 33 in large quantities. The drive unit 41 controls the squeezing part 42 to push open the partition 32. The partition 32 rotates downward to open the filter tank 3. The broken gel-like substance on the filter tank 3 falls into the filter chamber 2 for collection, thus achieving separation from the liquid wastewater.

[0067] It should be noted that the driving component 41 can be a telescopic mechanism such as a cylinder or hydraulic cylinder. The side of the extrusion part 42 near the movable end of the driving component 41 is connected to a telescopic rod, which can extend according to the extension of the movable end of the driving component 41, and can protect the movable end of the driving component 41 from being contaminated by gel or impurities during reciprocating motion. The length of the filter tank 3 is greater than the length of the collection tank 21. During the movement of the driving component 41, a large amount of gel will fall into the filter chamber 2 towards the side of the partition 32. A small amount of gel will also cross the extrusion part 42 in the opposite direction. When the extrusion part 42 returns, it can push these gels into the filter chamber 2 for collection.

[0068] It should also be noted that the pressure block is arc-shaped, which makes it easy to rotate the extrusion block 5. The pressure block is also relatively high and has a transitional fit with the through hole 35, so that it can pass smoothly through the through hole 35 without having a large gap with the through hole 35, thus preventing a large amount of gelatinous material from falling from the through hole 35.

[0069] Example 3:

[0070] like Figure 2 As shown, the bottom surface of filter chamber 2 slopes downward on the side away from the feeding mechanism.

[0071] like Figure 1As shown, several sedimentation tanks are formed downwards inside the sewage tank. A drying chamber is connected to the bottom of the filter chamber 2, and a filter press is connected to the side of the drying chamber away from the filter chamber 2.

[0072] Specifically, the bottom of the filter chamber 2 is inclined, which can concentrate the colloidal material falling from both sides of the filter tank 3 at the lowest point for easy collection. After a certain amount of colloidal material is collected, it is discharged to the drying chamber, where the broken colloidal material and large-particle impurities are dried and dehydrated. After drying, it is discharged into the filter press, where the dried impurities are compressed into cake or block structures that are easy to store and collect for further impurity treatment in the later stage.

[0073] The sedimentation tank in the wastewater pond is used to settle solid particles in the solid battery waste liquid. This allows the waste liquid to reduce the content of solid impurities before flowing into the discharge chamber 1, thereby reducing the labor intensity of subsequent treatment processes.

[0074] Example 4:

[0075] In the discharge system of this utility model, the sludge and large-particle solid impurities left by sedimentation in the sewage tank and sedimentation tank are screened out by a filter screen in the later stage. The sludge can be collected separately and sent to a filter press to make sludge cake. The water collection tank at the bottom of the discharge chamber 1 contains the waste liquid and wastewater separated by the filter tank 3. Of course, there may also be colloidal debris and very small solid impurities that cannot be blocked by the leakage holes 33 of the filter tank 3, but the content of these impurities is not large, and the industry allows for a small amount of impurities. After sedimentation, the wastewater in the water collection tank can be discharged into the reaction tank through the discharge pipe. By adding chemical agents and other means, the discharged wastewater is treated and can meet the discharge standards after multiple reactions and adjustments.

[0076] The measures described above are used to reduce the content of various impurities in solid-state battery waste liquid in the early stage, separate impurities of different phases, improve the efficiency of water treatment in the later stage, and also reduce labor intensity.

[0077] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
