Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and in particular to a gas separator and vacuum system. Background Technology

[0002] Lithium-ion batteries, as a new type of rechargeable battery, have advantages such as high energy density and power density, high operating voltage, light weight, small size, long cycle life, good safety, and environmental friendliness. They have broad application prospects in portable electrical appliances, power tools, large-scale energy storage, and electric transportation power supplies.

[0003] In industrial production, lithium battery manufacturing processes are divided into electrode preparation, pre-processing, post-processing, and capacity measurement. These processes include stirring, liquid injection, winding, and assembly. Vacuum systems are used in these production scenarios to provide power for the processes. According to on-site process requirements, the vacuum system is directly connected to the equipment. Therefore, during the stirring and liquid injection processes, the negative pressure of the vacuum often causes some raw materials to be drawn away. For example, during the stirring process, when evacuating the tank, some carbon powder can be sucked into the vacuum system, causing blockages. In severe cases, this can directly contaminate the lubricating oil of the vacuum pump, leading to overheating and shutdown, thus directly affecting production. Similarly, the liquid injection process can also cause crystallization in the pipes, resulting in similar blockages. Therefore, how to effectively separate gases and raw materials in the vacuum system becomes a pressing problem to be solved.

[0004] In related technologies, filters are used to filter raw materials. However, traditional filters do not completely separate raw materials from gases, and can still clog pipelines and contaminate vacuum pumps. Summary of the Invention

[0005] In view of the above problems, this application provides a gas separator and vacuum system, which aims to improve the separation effect of raw materials and gas, so as to solve the problem that raw materials will clog the pipeline and contaminate the vacuum pump.

[0006] This application provides a gas separator, including a housing, an inlet pipe, and a cutting element; the housing has an installation port and an outlet; the inlet pipe has an inlet and a passage, one end of the inlet pipe with the passage extends into the housing from the installation port, the passage including an end opening at the end of the inlet pipe and a side opening on the side wall of the inlet pipe; a cutting element is provided on the outlet path between the passage and the outlet, the cutting elements are spaced apart on the outer periphery of the inlet pipe, the cutting element includes at least two layers of cutting elements, the at least two layers of cutting elements are spaced apart along the direction from the bottom wall to the top wall of the housing; the cutting element has an air passage connecting the passage and the outlet, the air passage is used for fluid to pass through the cutting element.

[0007] In the technical solution of this application embodiment, the technical solution of the present invention sets the inlet of the air inlet pipe as an end opening at the end of the air inlet pipe and a side opening on the side wall of the air inlet pipe. After the fluid enters the air inlet pipe from the air inlet, it can first achieve pressure relief through the side opening to reduce the flow pressure of the fluid, so that the pressure of the fluid flowing out from the end opening is smaller and the flow rate is slower, thereby causing the raw material to continuously accumulate under its own gravity, forming large particles and settling. Through the continuous cycle of the above process, the raw material is continuously separated from the fluid to gradually fill the shell, thereby realizing the gas-solid and gas-liquid separation of the fluid, effectively improving the separation effect of raw material and gas, and solving the problem that raw material will block the pipeline and contaminate the vacuum pump. Furthermore, by providing a cutting element along the air outlet path between the inlet and outlet, and the cutting element comprising at least two layers of cutting elements spaced apart along the direction from the bottom wall to the top wall of the housing, when the fluid carrying raw materials is drawn in by the vacuum system, the fluid enters the inlet pipe from the inlet and then impacts the cutting element from the outlet of the inlet pipe. The fluid is better cut into two parts by the cutting element; one part moves along the top of the cutting element, and the other part moves along the bottom of the cutting element. When the two fluids meet in the inner cavity between two adjacent layers of cutting elements, the air forces in that inner cavity cancel each other out, thereby... The raw materials accumulate and settle into large particles within the cavity between adjacent cutting elements. Furthermore, because the cutting elements have air passages connecting the inlet and outlet, some fluid flows from one side of the cutting element to the other side, causing turbulence between the cutting elements and extending the fluid's flow path. This further enhances the separation of raw materials and gas, resulting in the accumulation of large particles within the cavity between adjacent cutting elements and within the air passages.

[0008] In some embodiments, the opening of the end opening gradually increases along the outlet direction. This design allows for effective pressure relief of the fluid as it flows through the funnel-shaped end opening, further reducing the pressure and slowing the flow rate of the fluid exiting the end opening.

[0009] In some embodiments, the sidewall of the intake pipe is provided with multiple side openings. This design allows for effective pressure relief of the fluid as it flows through the multiple side openings, further reducing the pressure and slowing the flow rate of the fluid exiting from the end openings.

[0010] In some embodiments, the housing includes an outer shell and an inner shell; the outer shell has an installation port and an air outlet; the inner shell is disposed inside the outer shell and communicates with the outer shell; one end of the air inlet pipe with an outlet is inserted into the inner shell through the installation port. This design, by providing an inner shell within the outer shell so that one end of the air inlet pipe can be inserted into the inner shell through the installation port, allows a small amount of raw material to overflow from the inner shell into the outer shell as the inner shell becomes full with time and increased usage frequency. At this point, the presence of raw material settling on the bottom wall of the outer shell can be used to determine whether the gas separator needs cleaning, further preventing pipe blockage.

[0011] In some embodiments, the top of the inner shell is provided with a communication port communicating with the outer shell, and a first filter cotton is also provided inside the inner shell, located on the air outlet path between the passage and the communication port. With this design, when the fluid carrying a small amount of raw material rises, the first filter cotton acts as a barrier, allowing gas in the fluid to pass through. The gas can then enter the outer shell from the communication port at the top of the inner shell. Simultaneously, the first filter cotton can block the raw material in the fluid, thereby further achieving gas-solid and gas-liquid separation.

[0012] In some embodiments, the first filter cotton has at least two layers. This design, with at least two layers of the first filter cotton, can better block raw materials in the fluid, thereby further improving the gas-solid and gas-liquid separation effect.

[0013] In some embodiments, a second filter cotton is also provided inside the housing, located between the inner housing and the air outlet. With this design, over time and with increased usage frequency, the raw materials will eventually overflow into the outer housing through the first filter cotton in the inner housing. As the fluid flow rate slows down, the gas in the fluid can pass through the second filter cotton and eventually flow from the air outlet to the vacuum pump. At the same time, the raw materials in the fluid will be blocked by the second filter cotton and fall into the interior of the housing, thereby further achieving the effect of gas-solid and gas-liquid separation through the second filter cotton.

[0014] In some embodiments, the cutting element is disposed within the inner shell, and at least two layers of cutting elements are spaced apart along the direction from the bottom wall to the top wall of the inner shell. With this design, by installing the cutting element in the inner shell, over time and with increased usage frequency, the raw materials in the fluid can be fully separated and settled in the inner shell through the cutting and blocking action of the cutting element. When the inner shell is full of raw materials, it can be directly removed for cleaning.

[0015] In some embodiments, the air outlet is located at the top of the outer casing, and the inlet is positioned close to the inner bottom wall of the inner casing. This design, by placing the air outlet at the top of the outer casing and positioning the inlet of the air inlet close to the inner bottom wall of the inner casing, allows the fluid flowing out of the inlet to be cut into two parts by the cutting element. One part of the fluid moves above the cutting element, and the other part moves below it. When the two fluid streams meet in the inner cavity between two adjacent cutting elements, the air forces within that cavity cancel each other out. Furthermore, this allows the raw materials to better accumulate under gravity, forming larger particles that then settle.

[0016] In some embodiments, the cutting element is annular and surrounds the air inlet pipe. The annular cutting element has multiple air passages spaced circumferentially. This design allows the fluid to be cut by the annular cutting element regardless of the direction from which it flows from the air inlet pipe to the inner wall of the housing. This allows the raw material to accumulate and form larger particles that then settle. Furthermore, by providing multiple air passages spaced circumferentially on the annular cutting element, the fluid can pass through the cutting element at different locations, creating stronger turbulence between the layers of cutting elements. This further extends the fluid flow path, allowing the raw material to remain in the cavity between adjacent layers of cutting elements, continuously accumulating and forming larger particles that then settle.

[0017] In some embodiments, the cutting element includes at least two cutting units, which are spaced apart circumferentially and / or radially along the air inlet pipe, with an air passage formed between adjacent cutting units. This design allows for the use of at least two cutting units joined together to form a cutting element, creating an air passage between adjacent cutting units. When fluid flows over one side surface of a cutting unit, some fluid flows along the peripheral wall of the cutting unit and through the air passage to the other side surface of the cutting unit, further extending the fluid flow path. This allows the raw material to accumulate and form large particles in the cavity between adjacent cutting elements and in the air passage, eventually settling.

[0018] In some embodiments, the cutting unit is circular or semi-circular. This design allows the sidewalls of the cutting unit to be arc-shaped, resulting in a gradually changing cross-sectional width of the air passage. This increases the flow resistance of the fluid as it flows through the air passage, causing the raw material to remain in the air passage more effectively, accumulate, and eventually settle into larger particles.

[0019] In some embodiments, the cutting element is detachably connected to the inner wall of the inner shell. This design allows the cutting element to be removed from the inner shell when the gas separator needs to be cleaned, making it easier to clean the raw materials accumulated on the cutting element and also easier to clean the raw materials accumulated in the inner shell.

[0020] In some embodiments, the number of cutting elements is 17 to 25. With this design, if the number of cutting elements is too small, the number of cuts to the fluid is too low, preventing the raw materials in the fluid from effectively accumulating; while if the number of cutting elements is too large, a larger housing is required, increasing costs. Therefore, by controlling the number of cutting elements to 17 to 25, the number of cuts to the fluid by the cutting elements can be effectively increased, allowing the raw materials in the fluid to accumulate sufficiently to form large particles and settle, achieving better gas-solid and gas-liquid separation effects, while also controlling costs.

[0021] In some embodiments, the width of the cutting element is defined as w, satisfying the condition: 100mm ≤ w ≤ 270mm. With this design, if the width of the cutting element is too small, the path of the fluid flowing through it will be too narrow, resulting in insufficient resistance and preventing the effective accumulation of raw materials. Conversely, if the width is too large, a larger housing is required, increasing costs. Therefore, by controlling the width of the cutting element between 100mm and 270mm, the flow path and resistance of the fluid flowing through the cutting element can be effectively increased, allowing the raw materials in the fluid to accumulate sufficiently to form large particles and settle, achieving better gas-solid and gas-liquid separation while controlling costs.

[0022] In some embodiments, the housing is provided with an observation window. This design allows users to directly observe the raw materials settling on the bottom wall of the housing through the observation window, so as to determine whether the gas separator needs to be cleaned, and thus observe the internal condition of the housing without opening it.

[0023] In some embodiments, the observation window is located at the bottom of the housing. This design allows users to observe the raw materials settling on the bottom wall of the housing more promptly.

[0024] In some embodiments, the housing is also provided with an exhaust port. This design allows the inlet and outlet ports to be closed and the exhaust port to be opened when the gas separator needs to be cleaned, thereby achieving pressure balance between the inside and outside, which facilitates disassembly and cleaning of the gas separator.

[0025] This application also provides a vacuum system, including the gas separator and vacuum pump described above, wherein the vacuum pump is connected to the outlet of the gas separator.

[0046] Lithium-ion batteries, as a new type of rechargeable battery, have advantages such as high energy density and power density, high operating voltage, light weight, small size, long cycle life, good safety, and environmental friendliness. They have broad application prospects in portable electrical appliances, power tools, large-scale energy storage, and electric transportation power supplies.

[0047] In industrial production, lithium battery manufacturing processes are divided into electrode preparation, pre-processing, post-processing, and capacity measurement. These processes include stirring, liquid injection, winding, and assembly. Vacuum systems are used in these production scenarios to provide power for the processes. According to on-site process requirements, the vacuum system is directly connected to the equipment. Therefore, during the stirring and liquid injection processes, the negative pressure of the vacuum often causes some raw materials to be drawn away. For example, during the stirring process, when evacuating the tank, some carbon powder can be sucked into the vacuum system, causing blockages. In severe cases, this can directly contaminate the lubricating oil of the vacuum pump, leading to overheating and shutdown, thus directly affecting production. Similarly, the liquid injection process can also cause crystallization in the pipes, resulting in similar blockages. Therefore, how to effectively separate gases and raw materials in the vacuum system becomes a pressing problem to be solved.

[0048] In related technologies, filters are used to filter raw materials. However, traditional filters do not completely separate raw materials from gases, and can still clog pipelines and contaminate vacuum pumps.

[0049] Based on the above problems, the present invention proposes a gas separator 100, which aims to improve the separation effect of raw materials and gas, so as to solve the problem that raw materials will clog the pipeline and contaminate the vacuum pump.

[0050] Please see Figures 1 to 4In one embodiment of the present invention, the gas separator 100 includes a housing 10 and an inlet pipe 20; the housing 10 is provided with an installation port 11a and an outlet port 11b; the inlet pipe 20 is provided with an inlet port 20a and an outlet port 20b, one end of the inlet pipe 20 with the outlet port 20b extends into the housing 10 from the installation port 11a, the outlet port 20b includes an end opening 20b1 at the end of the inlet pipe 20 and a side opening 20b2 on the side wall of the inlet pipe 20; a cutting element 30 is provided on the air outlet path between the outlet port 20b and the outlet port 11b, the cutting elements 30 are spaced apart on the outer periphery of the inlet pipe 20, the cutting element 30 includes at least two layers of cutting elements 31, the at least two layers of cutting elements 31 are spaced apart along the direction from the bottom wall to the top wall of the housing 10; the cutting element 31 is provided with an air passage 31a connecting the outlet port 20b and the outlet port 11b, the air passage 31a is used to allow fluid to pass through the cutting element 31.

[0051] Understandably, the housing 10 can be a hollow cylindrical structure or a hollow prismatic structure, used to install and fix structures such as the intake pipe 20 and the cutting piece 30. The mounting port 11a of the housing 10 is used to install the intake pipe 20, so that the end of the intake pipe 20 with the through port 20b can be inserted into the interior of the housing 10 through the mounting port 11a.

[0052] Optionally, the outlet 11b of the housing 10 may be provided with an outlet pipe to connect the outlet 11b to the vacuum pump.

[0053] In practical applications, the housing 10 can be a single-layer housing or a double-layer housing. When the housing 10 is a single-layer housing, the end of the air intake pipe 20 with the through port 20b can extend into the interior of the single-layer housing; when the housing 10 is a double-layer housing, the end of the air intake pipe 20 with the through port 20b can extend into the interior of the inner housing 12.

[0054] It is understandable that the end opening 20b1 at the end of the intake pipe 20 faces the inner bottom wall of the housing 10, and the side opening 20b2 at the side wall of the intake pipe 20 faces the inner side wall of the housing 10.

[0055] The cutting element 30 refers to a structure capable of cutting the flowing fluid. Specifically, the cutting element 30 can be a cutting element 30 having at least two layers of cutting elements 31, or it can be a cutting plate, cutting teeth, etc., as long as it can cut the fluid. The cutting elements 31 of the cutting element 30a refer to a structure capable of cutting the flowing fluid, such as a blade.

[0056] In one embodiment, the surface of the cutting element 31 is a rough surface. When the fluid flows through the cutting element 31, the raw material can be better deposited on the surface of the cutting element 31. The raw material deposited on the surface of the cutting element 31 can further increase the roughness of the surface of the cutting element 31, thereby enabling better subsequent raw material deposit.

[0057] In summary, the technical solution of this application embodiment, by configuring the inlet 20b of the air inlet pipe 20 as an end opening 20b1 at the end of the air inlet pipe 20 and a side opening 20b2 on the side wall of the air inlet pipe 20, allows the fluid to first be depressurized through the side opening 20b2 after entering the air inlet 20a, thereby reducing the fluid flow pressure. This results in a lower pressure and slower flow velocity of the fluid flowing out from the end opening 20b1, causing the raw materials to continuously accumulate under their own gravity, forming large particles and settling. Through the continuous cycle of the above process, the raw materials are continuously separated from the fluid to gradually fill the shell 10, thereby achieving gas-solid and gas-liquid separation of the fluid, effectively improving the separation effect of raw materials and gas, and solving the problem of raw materials clogging the pipeline and contaminating the vacuum pump. Furthermore, by providing a cutting element 30 in the air outlet path between the inlet 20b and the outlet 11b, and the cutting element 30 comprising at least two layers of cutting elements 31 spaced apart along the direction from the bottom wall to the top wall of the housing 10, when the fluid carrying raw materials is drawn in by the vacuum system, the fluid enters the intake pipe 20 from the inlet 20a, and then impacts the cutting element 31 from the inlet 20b of the intake pipe 20. The fluid is better cut into two parts by the cutting element 31, one part of the fluid moves along the top of the cutting element 31, and the other part moves along the bottom of the cutting element 31. When the two fluids meet in the inner cavity between the two adjacent layers of cutting elements 31, they will cancel each other out due to air pressure in the inner cavity. This causes the raw materials to accumulate and settle into large particles within the cavity between two adjacent cutting elements 31. Furthermore, because the cutting element 31 has an air passage 31a connecting the inlet 20b and the outlet 11b, when the fluid flows across one side of the cutting element 31, some fluid flows from the air passage 31a to the other side of the cutting element 31. This causes turbulence between the cutting elements 31 and extends the fluid's flow path, further enhancing the separation effect between the raw materials and the gas.

[0058] In one embodiment of this application, in conjunction with reference to Figure 1 The opening of the end opening 20b1 gradually increases along the air outlet direction, that is, the end opening 20b1 is funnel-shaped.

[0059] With this design, when the fluid flows through the funnel-shaped end opening 20b1, the pressure of the fluid flowing out of the end opening 20b1 can be further reduced, and the flow rate can be further slowed down.

[0060] In one embodiment of this application, in conjunction with reference to Figure 1 The side wall of the intake pipe 20 is provided with multiple side openings 20b2. With this design, when the fluid flows through the multiple side openings 20b2, the pressure of the fluid flowing out from the end opening 20b1 can be further reduced and the flow rate can be further slowed down.

[0061] In some embodiments, multiple side openings 20b2 can be distributed at intervals on the same circumferential surface of the intake pipe 20, so that the fluid can flow evenly from the multiple side openings 20b2 on the same circumferential surface to the first obstruction on the outer periphery, thereby achieving a better pressure relief effect and further slowing down the flow rate.

[0062] Alternatively, multiple side openings 20b2 can be distributed at intervals along the axial direction of the air inlet pipe 20, allowing the fluid to gradually depressurize from the multiple axially distributed side openings 20b2, thereby further slowing down the flow rate.

[0063] Multiple side openings 20b2 can also be distributed at intervals along a spiral extension on the side wall of the intake pipe 20.

[0064] In one embodiment of this application, in conjunction with reference to Figure 1 The housing 10 includes an outer shell 11 and an inner shell 12; the outer shell 11 is provided with an installation port 11a and an air outlet 11b; the inner shell 12 is disposed inside the outer shell 11 and communicates with the outer shell 11; one end of the air inlet pipe 20 is inserted into the inner shell 12 from the installation port 11a.

[0065] Understandably, the outer shell 11 and the inner shell 12 form a double-shell structure design. One end of the air intake pipe 20 is inserted into the interior of the outer shell 11 through the mounting port 11a, and then into the interior of the inner shell 12.

[0066] With this design, an inner shell 12 is provided inside the outer shell 11 so that one end of the air inlet pipe 20 with the outlet 20b is inserted into the inner shell 12 from the mounting port 11a. As time goes by and the frequency of use increases, when the inner shell 12 is filled with raw materials, a small amount of raw materials will overflow from the inner shell 12 into the outer shell 11. At this time, the gas separator 100 can be judged whether it needs to be cleaned by observing the raw materials that have settled on the bottom wall of the outer shell 11, which can further avoid the occurrence of pipeline blockage.

[0067] In one embodiment, the outer casing 11 may include an outer bottom casing 111 and an outer top cover 112. The outer top cover 112 may be mounted on the outer bottom casing 111 using a latch 113, which facilitates the installation of the inner casing 12 into the outer casing 11. Of course, in other embodiments, the outer top cover 112 may also be mounted on the outer bottom casing 111 using bolts or other methods.

[0068] In one embodiment, the inner shell 12 may include an inner bottom shell 121 and an inner top cover 122, the inner top cover 122 being mounted on the inner bottom shell 121 using screws 123. Of course, in other embodiments, the inner top cover 122 may also be mounted on the inner bottom shell 121 using snaps or other methods.

[0069] In one embodiment, the intake pipe 20 can be mounted on the inner wall of the housing 11 using a clamp 21 to improve the installation reliability of the intake pipe 20. Of course, in other embodiments, the intake pipe 20 can also be mounted on the inner wall of the housing 11 using bolts or other methods.

[0070] In one embodiment of this application, in conjunction with reference to Figure 1 The top of the inner shell 12 is provided with a communication port 12a that communicates with the outer shell 11. The inner shell 12 is also provided with a first filter cotton 40, which is located on the air outlet path between the outlet 20b and the communication port 12a.

[0071] Understandably, the upper and lower layers of the first filter cotton 40 adopt a hollow design to allow for effective gas penetration and to effectively block solids and liquids.

[0072] With this design, when the fluid carries a small amount of raw material upwards, the first filter cotton 40 acts as a barrier, allowing gas in the fluid to pass through. The gas can then enter the outer shell 11 through the connecting port 12a at the top of the inner shell 12. At the same time, the first filter cotton 40 can block the raw material in the fluid, thereby further achieving the effect of gas-solid and gas-liquid separation.

[0073] In practical applications, the first filter cotton 40 can be G4 cotton, activated carbon filter cotton, glass fiber filter cotton, etc., as long as it can separate the solid and liquid in the fluid.

[0074] Optionally, the first filter cotton 40 can be G4 cotton.

[0075] It should be noted that G4 cotton is a high-efficiency filter material, mainly composed of polyester fibers and bonding fibers. Polyester fibers are synthetic fibers with high strength, good heat resistance, no shrinkage, and no fading; bonding fibers are a fiber mixture with good durability, softness, and ease of processing. These two fibers are bonded together using thermal fusion technology to form G4 cotton, which has excellent filtration effect and long-term stability.

[0076] In one embodiment of this application, in conjunction with reference to Figure 1 The first filter cotton 40 has at least two layers.

[0077] Understandably, at least two layers of first filter cotton 40 are stacked in sequence.

[0078] This design, employing at least two layers of first filter cotton 40, can better block raw materials in the fluid, thereby further improving the gas-solid and gas-liquid separation effect.

[0079] In one embodiment of this application, in conjunction with reference to Figure 1 The outer shell 11 is also provided with a second filter cotton 50, which is located between the inner shell 12 and the air outlet 11b.

[0080] Understandably, the upper and lower layers of the second filter cotton 50 adopt a hollow design to allow for effective gas penetration and effective blocking of solids and liquids.

[0081] With this design, as time goes by and the frequency of use increases, the raw materials will eventually overflow into the outer shell 11 through the first filter cotton 40 in the inner shell 12. As the fluid flow rate slows down, the gas in the fluid can pass through the second filter cotton 50 and eventually flow from the outlet 11b to the vacuum pump. At the same time, the raw materials in the fluid will be blocked by the second filter cotton 50 and fall into the interior of the outer shell 11, thereby achieving further gas-solid and gas-liquid separation through the second filter cotton 50.

[0082] In practical applications, the second filter cotton 50 can also be G4 cotton, activated carbon filter cotton, glass fiber filter cotton, etc., as long as it can separate the solid and liquid in the fluid.

[0083] Alternatively, the second filter cotton 50 can also be G4 cotton.

[0084] In one embodiment of this application, in conjunction with reference to Figure 1 The cutting element 31 is disposed inside the inner shell 12, and at least two layers of cutting elements 31 are spaced apart along the direction from the bottom wall to the top wall of the inner shell 12.

[0085] With this design, by installing the cutting element 31 in the inner shell 12, the raw materials in the fluid can be fully separated and settled in the inner shell 12 under the cutting and blocking of the cutting element 31 over time and with the increase of usage frequency. When the inner shell 12 is full of raw materials, the inner shell 12 can be directly removed for cleaning.

[0086] In one embodiment of this application, in conjunction with reference to Figure 1 The air outlet 10b is located at the top of the outer shell 11, and the through-hole 20b is located near the inner bottom wall of the inner shell 12.

[0087] This design, by placing the air outlet 11b at the top of the outer casing 11 and positioning the inlet 20b of the air inlet pipe 20 close to the inner bottom wall of the inner casing 12, allows the fluid flowing out from the inlet 20b to be cut into two parts by the cutting element 31. One part of the fluid moves along the top of the cutting element 31, and the other part moves along the bottom of the cutting element 31. When the two fluid streams meet in the inner cavity between two adjacent layers of cutting elements 31, they cancel each other out due to air pressure within that cavity. Furthermore, this design allows the raw materials to better accumulate under gravity, forming larger particles that then settle.

[0088] In one embodiment of this application, in conjunction with reference to Figure 4 The cutting element 31 is annular and surrounds the air inlet pipe 20. The annular cutting element 31 has multiple air passages 31a spaced apart circumferentially. This design allows the fluid to be cut by the annular cutting element 31 regardless of the direction from which it flows from the air inlet pipe 20 to the inner wall of the housing 10, thus allowing the raw material to accumulate and form large particles that settle. In addition, by providing multiple air passages 31a spaced apart circumferentially on the annular cutting element 31, the fluid can pass through the cutting element 31 at different positions, causing the fluid to flow between the layers of cutting elements 31 and generating stronger turbulence. This further extends the fluid flow path, allowing the raw material to remain in the cavity between adjacent layers of cutting elements 31, continuously accumulating and forming large particles that settle.

[0089] In one embodiment of this application, in conjunction with reference to Figures 5 to 8 The cutting element 31 includes at least two cutting units 311, which are distributed at intervals along the circumferential and / or radial direction of the air intake pipe 20, and an air passage 31a is formed between two adjacent cutting units 311.

[0090] This design allows for the use of at least two cutting units 311 spliced ​​together to form a cutting element 31, creating an air passage 31a between two adjacent cutting units 311. When fluid flows through one side of the cutting unit 311, some fluid will flow along the peripheral wall of the cutting unit 311 and flow from the air passage 31a to the other side of the cutting unit 311, further extending the fluid flow path. This allows the raw material to accumulate and form large particles in the cavity between the two adjacent cutting elements 31 and in the air passage 31a, eventually settling.

[0091] In one embodiment of this application, in conjunction with reference to Figures 5 to 8 The cutting unit 311 is circular or semi-circular.

[0092] This design allows the sidewalls of the cutting unit 311 to be arc-shaped, and the cross-sectional width of the air passage 31a to be gradually changed. As the fluid flows through the air passage 31a, the flow resistance to the fluid increases, allowing the raw materials to stay and accumulate in the air passage 31a, forming large particles that then settle.

[0093] In one embodiment, in conjunction with reference to Figure 5 and Figure 6 The cutting element 31 includes multiple semi-circular cutting units 311, which are distributed circumferentially along the intake pipe 20. It should be noted that the semi-circular shape refers to a structure with a portion cut off relative to a circle, not half of a circle.

[0094] In another embodiment, in conjunction with reference to Figure 7 The cutting element 31 includes a plurality of circular cutting units 311, which are distributed at intervals along the circumference of the air intake pipe 20.

[0095] In yet another embodiment, in conjunction with reference to Figure 8 The cutting element 31 includes a plurality of circular cutting units 311. Some of the cutting units 311 are distributed circumferentially along the intake pipe 20, and others are distributed radially along the intake pipe 20.

[0096] In one embodiment of this application, in conjunction with reference to Figure 1 The cutting element 30 is detachably connected to the inner wall of the inner shell 12.

[0097] With this design, when the gas separator 100 needs to be cleaned, the cutting part 30 can be removed from the inner shell 12, which makes it easier to clean the raw materials accumulated on the cutting part 30 and also makes it easier to clean the raw materials accumulated in the inner shell 12.

[0098] In practical applications, the cutting part 30 can be detachably connected to the inner wall of the inner shell 12 by means of screws, clips, etc.

[0099] In one embodiment of this application, in conjunction with reference to Figure 1 The number of layers in the cutting element 31 is 17 to 25.

[0100] Understandably, the number of layers in the cutting element 31 can be 17, 18, 19, 20, 21, 22, 23, 24, or 25.

[0101] With this design, if the number of cutting elements 31 layers is too small, the number of cuts made by the cutting elements 31 on the fluid is too few, resulting in insufficient accumulation of raw materials in the fluid. Conversely, if the number of cutting elements 31 layers is too large, a larger housing 10 is required, leading to increased costs. Therefore, by controlling the number of cutting elements 31 layers to 17-25 layers, the number of cuts made by the cutting elements 31 on the fluid can be effectively increased, allowing the raw materials in the fluid to accumulate sufficiently to form large particles and settle, achieving better gas-solid and gas-liquid separation effects, while also controlling costs.

[0102] In one embodiment of this application, in conjunction with reference to Figure 1 If the width of the cutting element 31 is defined as w, then the following condition must be met: 100mm≤w≤270mm.

[0103] Understandably, the width of the cutting element 31 can be 100mm, 110mm, 130mm, 140mm, 150mm, 170mm, 200mm, 210mm, 240mm, 250mm, 270mm, etc.

[0104] With this design, if the width of the cutting element 31 is too small, the path of the fluid flowing through it will be too narrow, resulting in insufficient resistance from the cutting element 31 and preventing the raw materials in the fluid from effectively accumulating. Conversely, if the width of the cutting element 31 is too large, a larger housing 10 is required, increasing costs. Therefore, by controlling the width of the cutting element 31 between 100mm and 270mm, the flow path and resistance of the fluid flowing through the cutting element 30 can be effectively increased, allowing the raw materials in the fluid to accumulate sufficiently to form large particles and settle, achieving better gas-solid and gas-liquid separation effects while also controlling costs.

[0105] In one embodiment of this application, in conjunction with reference to Figure 1 The outer casing 11 is provided with an observation window 11c.

[0106] Understandably, the observation window 11c is a transparent window, allowing the user to observe the interior of the outer casing 11 through the observation window 11c.

[0107] With this design, users can directly observe the raw materials settling on the bottom wall of the outer casing 11 through the observation window 11c, so as to determine whether the gas separator 100 needs to be cleaned, and thus observe the inside of the outer casing 11 without opening it.

[0108] In practical applications, the observation window 11c can be set at the bottom of the housing 11 or on the side wall of the housing 11, as long as the situation inside the housing 11 can be observed through the observation window 11c.

[0109] Optionally, in one embodiment of this application, the observation window 11c is located at the bottom of the housing 11. This design allows the user to observe the raw materials settling on the bottom wall of the housing 11 more promptly.

[0110] In one embodiment of this application, in conjunction with reference to Figure 1 , Figure 3 The housing 10 is also provided with an exhaust port 11d.

[0111] In this embodiment, an exhaust valve is provided at the exhaust port 11d to open or close the exhaust port 11d.

[0112] With this design, when the gas separator 100 needs to be cleaned, the inlet 20a and outlet 11b can be closed and the exhaust port 11d opened to achieve internal and external pressure balance, thereby facilitating the disassembly and cleaning of the gas separator 100.

[0113] This application also proposes a vacuum system, which includes a gas separator 100 and a vacuum pump. The specific structure of the gas separator 100 is as described in the above embodiments. Since this vacuum system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The vacuum pump is connected to the outlet 11b of the gas separator 100.

[0114] According to some embodiments of this application, this application provides a gas separator 100, please refer to... Figures 1 to 3The gas separator 100 includes a housing 10, an inlet pipe 20, and a cutting element 30. The housing 10 has an inlet 20a with a mounting port 11a, located at the top of the housing 10. The inlet pipe 20 has an inlet 20a and an outlet 20b. One end of the inlet pipe 20 with the outlet 20b extends into the housing 10 from the mounting port 11a, and the outlet 20b is located near the inner bottom wall of the housing 10. The cutting element 30 is located inside the housing 10 and is spaced apart on the outer periphery of the inlet pipe 20. The cutting element 30 includes at least two layers of cutting elements 31, which are spaced apart along the direction from the bottom wall to the top wall of the housing 10. The housing 10 includes an outer shell 11 and an inner shell 12. The cutting element 30 is located inside the inner shell 12 and is spaced apart along the direction from the bottom wall to the top wall of the inner shell 12. The bottom of the outer shell 11 has an observation window 11c. The inner shell 12 is provided with a first filter cotton 40, and the outer shell 11 is provided with a second filter cotton 50. The inlet 20b of the air intake pipe 20 includes an end opening 20b1 at the end of the air intake pipe 20 and a side opening 20b2 on the side wall of the air intake pipe 20.

[0115] In the technical solution of this application embodiment, the gas separator 100 proposed by the present invention, when the fluid carrying raw materials (carbon powder or electrolyte) enters the inner shell 12 from the air inlet 20a, gradually depressurizes through the side opening 20b2 on the side wall of the air inlet pipe 20, and the end fluid flows out from the end opening 20b1. When the fluid passing through the side opening 20b2 is sucked in by the vacuum system, the fluid will collide with the cutting element 31, and the fluid will be cut into two parts by the cutting element 31. One part of the fluid moves along the top of the cutting element 31, and the other part moves along the bottom of the cutting element 31. When the two fluids meet in the inner cavity between two adjacent layers of cutting elements 31, they will be subjected to air force in the inner cavity and cancel each other out, so that the raw materials stay in the inner cavity between the two adjacent layers of cutting elements 31 and continuously accumulate to form large particles and settle. Furthermore, the cutting element 30 increases the fluid flow path and resistance, causing the fluid velocity to decrease as it rises. When the fluid velocity decreases to a certain level, the raw material will no longer flow with the fluid and will accumulate to form large particles that eventually settle. Through this continuous cycle, the raw material is constantly separated from the fluid, gradually filling the shell 10, thus achieving gas-solid and gas-liquid separation. This effectively improves the separation effect between raw material and gas, solving the problems of raw material clogging pipes and contaminating the vacuum pump.

[0116] When the remaining fluid, carrying a small amount of raw material, rises through the end opening 20b1, the first filter cotton 40 acts as a barrier, allowing gas in the fluid to pass through. The gas can then enter the outer shell 11 through the connecting port 12a at the top of the inner shell 12. Simultaneously, the first filter cotton 40 blocks the raw material in the fluid, thus further achieving gas-solid and gas-liquid separation. Over time and with increased usage frequency, the raw material will eventually overflow into the outer shell 11 through the first filter cotton 40 in the inner shell 12. As the fluid flow rate slows, the gas in the fluid can pass through the second filter cotton 50, eventually flowing from the outlet 11b to the vacuum pump. Meanwhile, the raw material in the fluid is blocked by the second filter cotton 50 and falls inside the outer shell 11. At this point, the user can observe the inner bottom wall of the outer shell 11 through the observation window 11c to determine whether the gas separator 100 needs cleaning, further preventing pipe blockage.

[0117] When cleaning of the gas separator 100 is required, simply switch the vacuum pump to the standby gas separator 100, close the inlet 20a and outlet 11b of the gas separator 100 to be cleaned, and open the exhaust port 11d to achieve internal and external pressure balance, thereby disassembling and cleaning the gas separator. After cleaning, reassemble in sequence, and after passing the airtightness test, it can be put into operation as a standby and enter the next cycle.

[0118] In lithium battery production applications, taking into full account the advantages and disadvantages of traditional filters, this invention provides a gas separator 100 suitable for vacuum systems in the lithium battery industry. It employs multi-layer cutting elements 31 to cut the fluid, achieving gas-solid / gas-liquid separation through three stages: fluid deceleration, solid / liquid accumulation, and sedimentation. This effectively solves the problems of carbon powder or electrolyte blockage and crystallization caused by direct vacuum extraction. Due to differences in specifications and materials, this invention also discloses material selection and dimensions for different specifications, as shown in Table 1 below. This solution closely integrates the gas flow principle with the actual industrial production, completely solving the problems of carbon powder or electrolyte blockage and crystallization. Moreover, the gas separator 100 disclosed in this invention only needs to be installed on the production site to meet usage requirements (no debugging required), and its manufacturing cost is extremely low, making it very easy to promote.

[0119] To better illustrate the effectiveness of this solution, this embodiment also provides equipment models and material selections for different sizes, as shown in the table below (Table 1):
