Description

Technical Field

[0001] This application relates to the field of energy storage technology, and in particular to a slurry homogenization device and a battery production system. Background Technology

[0002] With the development of new energy sources, more and more fields are adopting new energy as a power source. Due to its advantages such as high energy density, rechargeability, safety, and environmental friendliness, battery devices are widely used in new energy vehicles, consumer electronics, energy storage systems, and other fields.

[0003] The battery assembly includes individual battery cells, each containing an electrode assembly. During production, the electrode plates of the electrode assembly require coating with a slurry. This slurry needs to be processed by a homogenizer to improve coating quality. The homogenizer needs to monitor the homogenization of the slurry, and during this monitoring process, there is a risk of environmental pollution due to slurry dripping. Utility Model Content

[0004] In view of the above problems, this application provides a slurry homogenization device and a battery production system, which solves the problem of environmental pollution caused by slurry dripping during the testing process.

[0005] The first aspect of this application discloses a slurry homogenizing device, which includes:

[0006] A homogenizer includes an inlet and an outlet.

[0007] Piping assembly, which connects the inlet and outlet and supplies slurry flow;

[0008] A discharge valve is connected in series with the pipeline assembly and is used to discharge slurry.

[0009] The receiving components are spaced below the discharge valve and are used to receive the slurry dripping from the discharge valve.

[0010] The slurry homogenizing device of this application discharges slurry through a discharge valve during use to enable slurry testing. After the discharge is completed, a receiving device is placed below the discharge valve to catch the slurry dripping from the discharge valve, thereby reducing the possibility of slurry dripping onto the ground and causing environmental pollution.

[0011] In some embodiments of this application, the slurry homogenizing device further includes:

[0012] A circulation element, which is connected in series with the piping assembly and is used to drive the flow of slurry;

[0013] Two slurry tanks are connected in series on the piping assembly, and the two slurry tanks are located on opposite sides of the circulation component.

[0014] The circulation component is used to drive the flow of the slurry, thereby increasing the slurry circulation rate. The use of two slurry tanks can improve the homogenization effect of the slurry.

[0015] In some embodiments of this application, the two slurry tanks are a first slurry tank and a second slurry tank. The first slurry tank is located between the outlet and the inlet of the circulation component and is used to receive external slurry. The second slurry tank is located between the inlet and the outlet of the circulation component and is used to store slurry.

[0016] By setting up a first slurry tank and a second slurry tank, it is possible to replenish and store the slurry, thereby improving the slurry processing capacity.

[0017] In some embodiments of this application, the piping assembly includes:

[0018] The discharge port of the first slurry tank is connected to the inlet through the first pipeline;

[0019] The second pipeline connects the feed inlet of the second slurry tank to the discharge outlet.

[0020] The third pipeline connects the discharge port of the second slurry tank to the inlet of the circulation component.

[0021] The outlet of the fourth pipeline is connected to the feed port of the first slurry tank.

[0022] This configuration allows for a rational layout of the homogenizer, the first slurry tank, the second slurry tank, and the circulation components, which helps to improve the structural compactness of the slurry homogenizing device.

[0023] In some embodiments of this application, the piping assembly further includes a fifth piping, and the outlet of the circulation component, the fifth piping, the fourth piping, and the feed inlet of the first slurry tank are connected in sequence.

[0024] The fifth pipeline is arranged vertically, and the discharge valve is arranged on the fifth pipeline. The receiving component is connected to the discharge valve or the fifth pipeline and can swing. The swing surface of the receiving component intersects the vertical direction. The receiving component has a first state and a second state that can be switched between each other. In the first state, part of the receiving component is located below the discharge valve and is used to receive the slurry dripping from the discharge valve. In the second state, the receiving component avoids the lower part of the discharge valve so that the discharge valve can discharge the slurry.

[0025] By setting up the material receiving component, the receiving component can receive the slurry dripping from the discharge valve while reducing interference with the material receiving device during the process, thus facilitating the effective discharge operation.

[0026] In some embodiments of this application, the slurry homogenizing device further includes a connecting valve, which is arranged vertically above the discharge valve, and the fourth pipeline is connected to the fifth pipeline through the connecting valve.

[0027] By setting up a connecting valve, the flow of slurry can be controlled to determine whether the fourth and fifth pipelines are connected.

[0028] In some embodiments of this application, the receiving component includes:

[0029] A connecting rod, one end of which is connected to the discharge valve and is arranged in a vertical direction;

[0030] A support rod, one end of which is swayably connected to the other end of a connecting rod, with the support rod and the connecting rod intersecting each other.

[0031] The receiving tray is connected to the other end of the support rod. In the first state, the receiving tray is located below the discharge valve and is used to receive the slurry dripping from the discharge valve. In the second state, the receiving tray is positioned below the discharge valve so that the discharge valve can discharge the slurry.

[0032] By setting up docking components, the structure can be simplified while collecting the slurry dripping from the discharge valve, thereby reducing manufacturing costs.

[0033] In some embodiments of this application, the slurry homogenizing device further includes a temperature detection component, which is located in the fifth pipeline and used to detect the temperature of the slurry.

[0034] By setting up a temperature detection component, the temperature of the slurry can be detected, so as to control the slurry within a preset temperature range and reduce the adverse effects of temperature on the homogenization of the slurry.

[0035] In some embodiments of this application, the fifth conduit includes a first part and a second part that are isolated from each other. In the vertical direction, the first part is located above the second part, and the fourth conduit is connected to the outlet of the circulation component through the second part.

[0036] The temperature detection assembly includes a temperature sensing element and a display element. The display element is located outside the fifth pipeline. The temperature sensing element includes a main body and a sensing part. The main body is located inside the first part and is electrically connected to the display element. The sensing part is located inside the second part and is electrically connected to the main body.

[0037] This setup allows for real-time temperature display while simultaneously detecting the temperature, thus improving ease of use.

[0038] In some embodiments of this application, the slurry tank includes:

[0039] The tank body is provided with a feed inlet, a discharge inlet and a top opening, with the feed inlet located vertically above the discharge inlet.

[0040] The top cover is detachably connected to the tank body and closes the top opening.

[0041] This setup isolates the slurry from the outside environment during the homogenization process, reducing the adverse effects of external air on the slurry.

[0042] In some embodiments of this application, the slurry tank further includes a latch, and at least one of the tank body and the top cover is provided with a latch, the top cover being connected to the tank body via the latch.

[0043] This design facilitates the connection and disassembly of the top cover and the tank body, improving convenience during use.

[0044] In some embodiments of this application, the latches are provided on the top cover, and there are multiple latches, which are spaced apart along the circumference of the top cover. This arrangement can improve the connection strength between the top plate and the tank body.

[0045] In some embodiments of this application, the slurry tank further includes a seal disposed between the top cover and the tank body. This arrangement improves the sealing performance of the slurry tank and further reduces the adverse effects of external air on the slurry.

[0046] In some embodiments of this application, the sealing element is a sealing ring, with a raised ring on the outer side of the top opening and an annular groove on the sealing ring, the raised ring and the annular groove engaging in a concave-convex fit. This arrangement increases the sealing path, thereby improving the sealing performance between the top cover and the tank body.

[0047] In some embodiments of this application, the slurry tank further includes a pressure relief mechanism located on the top cover. This arrangement allows the pressure difference between the inside and outside of the slurry tank to be balanced, enabling the discharge valve to release the slurry.

[0048] In some embodiments of this application, a pressure relief hole is provided on the top cover, and the slurry tank also includes a pressure relief plug. The pressure relief plug and the pressure relief hole constitute the pressure relief mechanism. The pressure relief plug is detachably connected to the top cover and seals the pressure relief hole. This configuration simplifies the structure of the pressure relief mechanism, thereby effectively reducing manufacturing costs.

[0049] The second aspect of this application proposes a battery production system, which includes a slurry homogenizing device as described above.

[0050] The slurry homogenizing device of this application discharges slurry through a discharge valve during use to enable slurry testing. After the discharge is completed, a receiving device is placed below the discharge valve to catch the slurry dripping from the discharge valve, thereby reducing the possibility of slurry dripping onto the ground and causing environmental pollution.

[0081] Currently, judging from market trends, the application of battery devices is becoming increasingly widespread. Battery devices are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely applied in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of battery device applications, market demand is also constantly increasing.

[0082] The battery assembly includes individual battery cells, each containing an electrode assembly. During production, the electrode plates of the electrode assembly require coating with a slurry. This slurry needs to be processed by a homogenizer to improve coating quality. The homogenizer needs to monitor the homogenization of the slurry, and during this monitoring process, there is a risk of environmental pollution due to slurry dripping.

[0083] In this application, the slurry homogenizing device includes a homogenizer, a piping assembly, a discharge valve, and receiving components. The homogenizer includes an inlet and an outlet. The piping assembly connects the inlet and outlet and supplies slurry flow. The discharge valve is connected in series with the piping assembly and is used to discharge the slurry. The receiving components are spaced below the discharge valve and are used to collect the slurry dripping from the discharge valve. During use, the homogenizing device discharges the slurry through the discharge valve for slurry monitoring. After the discharge is complete, the receiving components are positioned below the discharge valve to collect the slurry dripping from it, thereby reducing the risk of slurry dripping onto the ground and causing environmental pollution.

[0084] The battery device described in the embodiments of this application can be applied to all electrical devices that use battery devices, such as electric vehicles.

[0085] For example, the electrical equipment can be a vehicle, which can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. The vehicle's interior can house a motor, a controller, and a battery pack. The controller is used to control the battery pack to supply power to the motor. For example, the battery pack can be located at the bottom, front, or rear of the vehicle. The battery pack can be used to power the vehicle; for example, it can serve as the vehicle's operating power source for the vehicle's electrical system, such as meeting the power requirements for starting, navigation, and operation. In another embodiment of this application, the battery pack can not only serve as the vehicle's operating power source but also as its driving power source, replacing or partially replacing gasoline or natural gas to provide driving power to the vehicle.

[0086] The aforementioned battery apparatus may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells connected in series, parallel, or in a mixed configuration via a busbar.

[0087] In some embodiments, a battery cell assembly is typically formed by arranging multiple battery cells.

[0088] As an example, a battery cell assembly can be a battery module, which is formed by arranging and fixing multiple battery cells together to form an independent module. As another example, a battery module can be formed by bundling multiple battery cells together with cable ties.

[0089] In some embodiments, the battery device may be a battery pack, which includes a housing and one or more individual battery cells housed within the housing.

[0090] In some embodiments, the battery cell can be a secondary battery, which refers to a battery cell that can be recharged to activate the active materials and continue to be used after the battery cell has been discharged.

[0091] The battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and the embodiments of this application are not limited to this.

[0092] As an example, the battery cell can be a cylindrical battery cell, a prismatic battery cell, a pouch battery cell, or a battery cell of other shapes. Prismatic battery cells include prismatic battery cells, blade-shaped battery cells, and multi-prismatic batteries, such as hexagonal prismatic batteries. This application does not have any particular limitations.

[0093] A single battery cell includes an electrode assembly, which comprises a positive electrode, a negative electrode, and a separator, with the separator positioned between the negative and positive electrodes. During the charging and discharging process of the battery cell, active ions (such as lithium ions) repeatedly insert and extract between the positive and negative electrodes. The separator, positioned between the positive and negative electrodes, serves to prevent short circuits between the electrodes while allowing active ions to pass through.

[0094] In some embodiments, the positive electrode may be a positive electrode sheet, which may include a positive electrode current collector and a positive electrode active material disposed on at least one surface of the positive electrode current collector.

[0095] As an example, the positive current collector has two surfaces opposite each other in its own thickness direction, and the positive active material is disposed on either or both of the two opposite surfaces of the positive current collector.

[0096] As an example, the positive current collector can be a metal foil, a conductive polymer material, a carbon material, or a composite current collector. For example, as a metal foil, pure metals, alloys, or surface-treated metals can be used, including but not limited to stainless steel, copper, aluminum, nickel, titanium, or silver. The composite current collector may include a polymer material base layer and a metal layer. The composite current collector can be formed by forming a metal material (aluminum, aluminum alloys, nickel, nickel alloys, titanium, titanium alloys, silver, and silver alloys, etc.) on a polymer material substrate (such as a substrate of polypropylene, polyethylene terephthalate, polybutylene terephthalate, polystyrene, polyethylene, etc.).

[0097] As an example, the positive electrode active material may include at least one of the following materials: lithium phosphate, lithium transition metal oxide, and their respective modified compounds. However, this application is not limited to these materials, and other conventional materials that can be used as battery positive electrode active materials may also be used. These positive electrode active materials may be used alone or in combination of two or more. Examples of lithium phosphate include, but are not limited to, at least one of lithium iron phosphate (such as LiFePO4 (also referred to as LFP)), lithium iron phosphate and carbon composites, lithium manganese phosphate (such as LiMnPO4), lithium manganese phosphate and carbon composites, lithium iron manganese phosphate, and lithium iron manganese phosphate and carbon composites. Examples of lithium transition metal oxides include, but are not limited to, lithium cobalt oxide (such as LiCoO2), lithium nickel oxide (such as LiNiO2), lithium manganese oxide (such as LiMnO2, LiMn2O4), lithium nickel cobalt oxide, lithium manganese cobalt oxide, lithium nickel manganese oxide, and lithium nickel cobalt manganese oxide (such as LiNi). 1 / 3 Co 1 / 3 Mn 1 / 3 O2 (also known as NCM) 333 LiNi 0.5 Co 0.2 Mn 0.3 O2 (also known as NCM) 523 LiNi 0.5 Co 0.25 Mn 0.25 O2 (also known as NCM) 211 LiNi 0.6 Co 0.2 Mn 0.2 O2 (also known as NCM) 622 LiNi 0.8 Co 0.1 Mn 0.1 O2 (also known as NCM) 811 ), lithium nickel cobalt aluminum oxide (such as LiNi) 0.8 Co 0.15 Al 0.05 At least one of O2 and its modified compounds. Modified compounds refer to substances obtained by modification methods such as doping or coating based on the above-mentioned substances.

[0098] As an example, the negative electrode current collector can be a metal foil, a conductive polymer material, a carbon material, or a composite current collector. For example, as a metal foil, pure metals, alloys, or surface-treated metals can be used, including but not limited to stainless steel, copper, aluminum, nickel, titanium, or silver. The composite current collector may include a polymer material substrate and a metal layer. The composite current collector can be formed by forming a metal material (copper, copper alloys, nickel, nickel alloys, titanium, titanium alloys, silver, and silver alloys, etc.) on a polymer material substrate (such as a substrate of polypropylene, polyethylene terephthalate, polybutylene terephthalate, polystyrene, polyethylene, etc.).

[0099] As an example, the negative electrode sheet may include a negative electrode current collector and a negative electrode active material disposed on at least one surface of the negative electrode current collector.

[0100] As an example, the negative electrode current collector has two surfaces opposite each other in its own thickness direction, and the negative electrode active material is disposed on either or both of the two opposite surfaces of the negative electrode current collector.

[0101] As an example, the negative electrode active material may be a negative electrode active material known in the art for use in battery cells. As an example, the negative electrode active material may include at least one of the following materials: artificial graphite, natural graphite, soft carbon, hard carbon, silicon-based materials, tin-based materials, and lithium titanate, etc. Silicon-based materials may be selected from at least one of elemental silicon, silicon oxide compounds, silicon-carbon composites, silicon-nitrogen composites, and silicon alloys. Tin-based materials may be selected from at least one of elemental tin, tin oxide compounds, and tin alloys. However, this application is not limited to these materials, and other conventional materials that can be used as negative electrode active materials for battery cells may also be used. These negative electrode active materials may be used alone or in combination of two or more.

[0102] Both the positive and negative active materials are applied to the current collector in the form of a slurry through coating.

[0103] In some embodiments, the separator is a separator membrane. This application does not impose any particular limitation on the type of separator membrane; any known porous separator membrane with good chemical and mechanical stability can be selected.

[0104] As an example, the main material of the separator can be selected from at least one of glass fiber, non-woven fabric, polyethylene, polypropylene, polyvinylidene fluoride, and ceramic. The separator can be a single-layer film or a multi-layer composite film, without particular limitation. When the separator is a multi-layer composite film, the materials of each layer can be the same or different, without particular limitation. The separator can be a single component located between the positive and negative electrodes, or it can be attached to the surfaces of the positive and negative electrodes. An inorganic particle coating, an organic particle coating, or an organic / inorganic composite coating can also be applied to the surface of the separator.

[0105] like Figures 1 to 5 As shown, in some embodiments of this application, a slurry homogenizing device 100 is proposed. The slurry homogenizing device 100 includes a homogenizer 10, a pipeline assembly 20, a discharge valve 30, and a receiving component 40. The homogenizer 10 includes an inlet 11 and an outlet 12. The pipeline assembly 20 is connected between the inlet 11 and the outlet 12 and supplies slurry flow. The discharge valve 30 is connected in series with the pipeline assembly 20 and is used to discharge slurry. The receiving component 40 is spaced below the discharge valve 30 and is used to receive the slurry dripping from the discharge valve 30.

[0106] Specifically, the homogenizer 10 is a device used to homogenize and mix slurry. The slurry enters the homogenizer 10 through the inlet 11, is homogenized by the homogenizer 10, and is then output through the outlet 12. The homogenizer 10 uses mechanical action or fluid dynamics to create high pressure, extrusion impact, and depressurization, causing the material to be extruded and ground under high pressure, sheared under strong impact, and expanded under depressurization. Under these three actions, the material achieves the purpose of refining and homogenizing. The homogenizer 10 can be a high-pressure homogenizer 10, a high-shear homogenizer 10, or an ultrasonic homogenizer 10, etc.

[0107] The pipeline assembly 20 forms a circulation loop between the feed inlet 11 and the discharge outlet 12 of the homogenizer 10. The homogenized slurry enters the circulation loop through the discharge outlet, and the slurry that has passed through the circulation loop returns to the homogenizer 10 through the feed inlet 11.

[0108] The discharge valve 30 is installed on the pipeline assembly 20 and forms a series structure with the circulation loop. When the slurry flows in the circulation loop, the slurry in the circulation loop can be discharged by opening the discharge valve 30, so as to realize the detection of the slurry.

[0109] After the slurry is discharged through the discharge valve 30, the discharge valve 30 is closed. The slurry remaining in the discharge valve 30 will drip out through the outlet of the discharge valve 30 under the action of gravity. The dripping slurry falling onto the ground or tabletop will cause environmental pollution.

[0110] The receiving element 40 is spaced below the discharge valve 30 and is positioned opposite the outlet of the discharge valve 30. The receiving element 40 has a receiving space on the side facing the discharge valve 30, with the opening of the receiving space facing the outlet of the discharge valve 30. When slurry drips from the outlet of the discharge valve 30, the dripping slurry enters the receiving space through the opening, thus collecting the dripping slurry.

[0111] In use, the slurry homogenizing device 100 of this application discharges slurry through the discharge valve 30 to enable slurry detection. After the discharge is completed, a receiving component 40 is placed below the discharge valve 30 to catch the slurry dripping from the discharge valve 30, thereby reducing the possibility of slurry dripping onto the ground and causing environmental pollution.

[0112] It should be noted that in the piping assembly 20, the piping material is stainless steel or corrosion-resistant flexible hose, etc.

[0113] In addition, the homogenizer 10 is provided with an inlet 13 and an outlet 14. The inlet 13 and the outlet 14 are connected to an external coolant circulation device, and the coolant is circulated into the homogenizer 10, thereby reducing the temperature rise of the slurry during the homogenization process, and thus reducing the impact of temperature rise on the slurry performance.

[0114] In some embodiments of this application, such as Figure 1 As shown, the slurry homogenizing device 100 also includes a circulation component 50 and two slurry tanks 60. The circulation component 50 is connected in series with the pipeline assembly 20 and is used to drive the slurry flow. The two slurry tanks 60 are connected in series with the pipeline assembly 20 respectively, and the two slurry tanks 60 are located on opposite sides of the circulation component 50.

[0115] Specifically, the circulation element 50 is connected to the piping assembly 20 and connected in series in the circulation loop. The circulation element 50 provides driving force for the flow of slurry in the circulation loop; for example, the circulation element 50 can be a circulation pump or a turbine. The circulation element 50 is used to drive the flow of slurry, thereby increasing the slurry circulation rate.

[0116] Two slurry tanks 60 are connected to the piping assembly 20. One slurry tank 60 is located between the circulation unit 50 and the inlet 11 of the homogenizer 10 and is used to receive external slurry to enable continuous slurry replenishment. The other slurry tank 60 is located between the circulation unit 50 and the outlet 12 of the homogenizer 10 and is used to buffer the homogenized slurry. This eliminates the need for immediate material receiving and testing, allowing for material receiving and testing at any time and reducing waiting time during testing.

[0117] In addition, by forming a closed loop using the pipeline assembly 20, the circulation component 50, the homogenizer 10, and the two slurry tanks 60, the slurry can be circulated. During the circulation process, the homogenizer 10 can be used to perform multiple homogenization operations on the slurry, thereby improving the homogenization effect of the slurry.

[0118] In some embodiments of this application, such as Figure 1As shown, the two slurry tanks 60 are a first slurry tank 61 and a second slurry tank 62. The first slurry tank 61 is located between the outlet and the inlet 11 of the circulation component 50 and is used to receive external slurry. The second slurry tank 62 is located between the inlet and the outlet 12 of the circulation component 50 and is used to store slurry.

[0119] It is important to understand that the structures of the first slurry tank 61 and the second slurry tank 62 can be the same or different. The following example assumes that the structures of the first slurry tank 61 and the second slurry tank 62 are the same.

[0120] The first slurry tank 61 is located between the inlet 11 of the homogenizer 10 and the outlet of the circulation component 50. Under the drive of the circulation component 50, the slurry flows from the outlet of the circulation component 50 through the first slurry tank 61 towards the inlet of the homogenizer 10. Thus, by adding external slurry into the first slurry tank 61, the added slurry can directly enter the homogenizer 10, so as to achieve homogenization of the slurry as soon as possible.

[0121] The second slurry tank 62 is located between the outlet 12 of the homogenizer 10 and the inlet of the circulation component 50. Under the drive of the circulation component 50, the slurry flows from the outlet 12 of the homogenizer 10 through the second slurry tank 62 toward the inlet of the circulation component 50. In this way, after the slurry homogenized by the homogenizer 10 enters the second slurry tank 62, the second slurry tank 62 can be used to buffer the homogenized slurry.

[0122] The discharge valve 30 can be set between the circulation component 50 and the second slurry tank 62, or between the circulation component 50 and the first slurry tank 61. This makes it easier for the discharge valve 30 to discharge the homogenized slurry.

[0123] In addition, by setting up the first slurry tank 61 and the second slurry tank 62, it is possible to replenish and store the slurry, thereby improving the slurry processing capacity.

[0124] In some embodiments of this application, such as Figure 1 As shown, the pipeline assembly 20 includes a first pipeline 21, a second pipeline 22, a third pipeline 23, and a fourth pipeline 24. The discharge port 63 of the first slurry tank 61 is connected to the inlet 11 through the first pipeline 21. The inlet port 64 of the second slurry tank 62 is connected to the discharge port 12 through the second pipeline 22. The discharge port 63 of the second slurry tank 62 is connected to the inlet of the circulation component 50 through the third pipeline 23. The outlet of the circulation component 50 is connected to the inlet port 64 of the first slurry tank 61 through the fourth pipeline 24.

[0125] Specifically, the first slurry tank 61 and the second slurry tank 62 are both located on top of the homogenizer 10 and are spaced apart from each other. The bottom of the first slurry tank 61 is connected to the homogenizer 10 via a support leg, and the bottom of the second slurry tank 62 is also connected to the homogenizer 10 via a support leg. Both the first slurry tank 61 and the second slurry tank 62 include a feed inlet 64 and a discharge inlet 63. The feed inlet 64 on the first slurry tank 61 is located above the discharge inlet 63, and the feed inlet 64 on the second slurry tank 62 is also located above the discharge inlet 63.

[0126] An outlet valve can be installed at the discharge port 63, and the opening and closing of the discharge port 63 can be controlled by controlling the state of the outlet valve. An inlet valve can be installed at the feed port 64, and the opening and closing of the feed port 64 can be controlled by controlling the state of the inlet valve.

[0127] The circulation component 50 is located on the side of the homogenizer 10. The first slurry tank 61, the second slurry tank 62, the feed inlet 11 of the homogenizer 10, the discharge outlet 12 of the homogenizer 10, the inlet of the circulation component 50, and the outlet of the circulation component 50 are interconnected through the pipeline assembly 20. This arrangement allows for a reasonable layout of the homogenizer 10, the first slurry tank 61, the second slurry tank 62, and the circulation component 50, which helps to improve the structural compactness of the slurry homogenizing device 100.

[0128] It should be noted that the first pipe 21, the second pipe 22, the third pipe 23 and the fourth pipe 24 can be rigid pipes or flexible pipes.

[0129] Alternatively, the first pipe 21, the second pipe 22, the third pipe 23, and the fourth pipe 24 can be connected to the homogenizer 10, which improves the stability of the pipeline. The first pipe 21, the second pipe 22, the third pipe 23, and the fourth pipe 24 can also be disconnected from the homogenizer 10, which reduces the number of connecting parts and lowers manufacturing costs.

[0130] In some embodiments of this application, such as Figure 1 As shown, the piping assembly 20 also includes a fifth pipe 25, and the outlet of the circulation component 50, the fifth pipe 25, the fourth pipe 24, and the feed inlet 64 of the first slurry tank 61 are connected in sequence. The fifth pipe 25 is arranged along the vertical direction X, and a discharge valve 30 is disposed on the fifth pipe 25. A receiving component 40 is connected to the discharge valve 30 or the fifth pipe 25 and is capable of swinging. The swinging surface of the receiving component 40 intersects the vertical direction X. The receiving component 40 has a first state and a second state that can be switched between each other. In the first state, part of the receiving component 40 is located below the discharge valve 30 and is used to receive the slurry dripping from the discharge valve 30. In the second state, the receiving component 40 avoids the area below the discharge valve 30 so that the discharge valve 30 can discharge the slurry.

[0131] Specifically, the fifth pipe 25 is arranged vertically in the X direction. The circulation component 50 and the fourth pipe 24 are respectively connected to the fifth pipe 25. The connection point between the circulation component 50 and the fifth pipe 25 is located below the connection point between the fourth pipe 24 and the fifth pipe 25. The fifth pipe 25 is connected to the homogenizer 10 through components such as the connecting rod 41, which improves the stability of the fifth pipe 25.

[0132] The discharge valve 30 is connected to the fifth pipeline 25. By setting the discharge valve 30 on the fifth pipeline 25, the discharge valve 30 is connected to the outlet side of the circulation component 50. This setting allows the discharge valve 30 to have sufficient pressure during the discharge process, which facilitates the discharge of slurry and enables the testing operation to proceed smoothly.

[0133] The receiving component 40 can swing relative to the connected component (discharge valve 30 or fifth pipeline 25). The swing surface of the receiving component 40 is arranged to intersect with the vertical direction X, so as to facilitate the switching of the receiving component 40 between the first state and the second state during use.

[0134] It should be noted that the fifth pipe 25 can be directly connected to the outlet of the circulation component 50, or it can be connected to the outlet of the circulation component 50 through a transition pipe.

[0135] The fifth pipe 25 can be directly connected to the fourth pipe 24, or it can be connected to the fourth pipe 24 through a valve or other components.

[0136] In this application, the material receiving component 40 is configured to receive the slurry dripping from the discharge valve 30 while reducing interference with the material receiving device during the process, thus facilitating the effective discharge operation.

[0137] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the slurry homogenizing device 100 also includes a connecting valve 70, which is arranged vertically X above the discharge valve 30. The fourth pipeline 24 is connected to the fifth pipeline 25 through the connecting valve 70.

[0138] Specifically, by setting a connecting valve 70, the fourth pipeline 24 and the fifth pipeline 25 are connected, thereby controlling the flow of slurry.

[0139] It is important to understand that when the discharge valve 30 discharges the slurry, the homogenizer 10 is shut down, the drive unit is activated, the connecting valve 70 is closed, and the discharge valve 30 is opened (the position of the second slurry tank 62 needs to be depressurized) in order to discharge the slurry.

[0140] In some embodiments of this application, such as Figure 1 and Figure 3 As shown, the receiving component 40 includes a connecting rod 41, a support rod 42, and a receiving tray 43. One end of the connecting rod 41 is connected to the discharge valve 30 and is arranged in the vertical direction X. One end of the support rod 42 is connected to the other end of the connecting rod 41 in a swingable manner. The support rod 42 and the connecting rod 41 are intersected. The receiving tray 43 is connected to the other end of the support rod 42. In the first state, the receiving tray 43 is located below the discharge valve 30 and is used to receive the slurry dripping from the discharge valve 30. In the second state, the receiving tray 43 avoids the lower part of the discharge valve 30 so that the discharge valve 30 can discharge the slurry.

[0141] Specifically, one end of the connecting rod 41 is fixedly connected to the discharge valve 30, and the other end of the connecting rod 41 is hinged to one end of the support rod 42. The receiving tray 43 is detachably connected to the other end of the support rod 42. The receiving tray 43 has a receiving space on the side facing the discharge valve 30, and the receiving space has an opening on the side facing the discharge valve 30.

[0142] The connecting rod 41, the support rod and the receiving plate 43 form the receiving component 40. By setting the receiving component 40, the structure can be simplified and the manufacturing cost can be reduced while collecting the slurry dripping from the discharge valve 30.

[0143] It should be understood that the receiving tray 43 and the support rod 42 can be detached. By separating the receiving tray 43, the slurry collected in the receiving tray 43 can be uniformly processed, and the receiving tray 43 can be cleaned.

[0144] In addition, the connection between the receiving plate and the support rod 42 can be a threaded connection or a snap-fit ​​connection.

[0145] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the slurry homogenizing device 100 also includes a temperature detection component 80, which is located in the fifth pipeline 25 and is used to detect the temperature of the slurry.

[0146] Specifically, by setting a temperature detection component 80, the temperature of the slurry can be detected, so as to control the slurry within a preset temperature range and reduce the adverse effects of temperature on the homogenization of the slurry.

[0147] In some embodiments of this application, such as Figure 2As shown, the fifth conduit 25 includes a first part 251 and a second part 252 that are isolated from each other. Along the vertical direction X, the first part 251 is located above the second part 252. The fourth conduit 24 is connected to the outlet of the circulation component 50 through the second part 252. The temperature detection assembly 80 includes a temperature sensing element 81 and a display element 82. The display element 82 is disposed outside the fifth conduit 25. The temperature sensing element 81 includes a main body 811 and a temperature sensing part 812. The main body 811 is disposed inside the first part 251 and is electrically connected to the display element 82. The temperature sensing part 812 is disposed inside the second part 252 and is electrically connected to the main body 811.

[0148] Specifically, by placing the main body 811 in the first part 251 and the temperature sensing part 812 in the second part 252, the corrosion of the main body 811 by the slurry is reduced, thereby extending the service life of the temperature sensing element 81.

[0149] It should be understood that the temperature sensing section 812 includes a temperature sensing end (such as a temperature sensor) of a hollow long rod. One end of the hollow long rod is connected to the main body 811 and extends into the second part 252. The temperature sensing end protrudes from the end of the hollow long rod away from the main body 811. The temperature sensing section is used to detect the temperature of the slurry. The hollow long rod protects the data line between the temperature sensing end and the main body 811, reducing the corrosion of the data line by the slurry.

[0150] In addition, the display element 82 is located outside the fifth pipe 25. This arrangement enables real-time temperature display while temperature is being detected, thereby improving the convenience of use.

[0151] It should be noted that the main body 811 has a controller, which is electrically connected to the temperature sensing end and the display unit 82 respectively. After receiving the data from the temperature sensing end, the controller controls the display unit 82 to display the data.

[0152] In some embodiments of this application, such as Figure 4 As shown, the slurry tank 60 includes a tank body 65 and a top cover 66. The tank body 65 is provided with a feed port 64, a discharge port 63 and a top opening. The feed port 64 is located above the discharge port 63 in a vertical direction X. The top cover 66 is detachably connected to the tank body 65 and closes the top opening.

[0153] Specifically, the slurry tank 60 is configured into two parts: a tank body 65 and a top cover 66. The top cover 66 is used to seal the top opening of the tank body 65, which can isolate the slurry from the outside world during the homogenization process and reduce the adverse effects of external air on the slurry.

[0154] In addition, the slurry tank 60 is configured as two parts: a tank body 65 and a top cover 66. By opening the top cover 66, it is convenient to add slurry into the tank body 65.

[0155] It should be noted that the connection between the top cover 66 and the tank body 65 can be achieved by snap-fit ​​or by connecting parts.

[0156] In some embodiments of this application, such as Figure 4 As shown, the slurry tank 60 also includes a latch 67, and at least one of the tank body 65 and the top cover 66 is provided with the latch 67. The top cover 66 is connected to the tank body 65 through the latch 67.

[0157] Specifically, the tube body is connected to the top cover 66 using the latch 67, which facilitates the connection and disassembly of the top cover 66 and the tank body 65, improving the convenience during use.

[0158] Taking the locking buckle 67 installed on the top cover 66 as an example, a flange is provided on the outer side of the top of the tank body 65. One end of the locking buckle 67 is hinged to the top cover 66, and the other end has a slot. When the locking buckle 67 is fixed, the slot of the locking buckle 67 abuts against the flange, and external pressure is used to make the flange embed into the slot. When the locking buckle 67 is released, external force drives the locking buckle 67, so that the flange separates from the slot.

[0159] In some embodiments of this application, such as Figure 4 As shown, the latch 67 is provided on the top cover 66, and there are multiple latches 67, which are spaced apart along the circumference of the top cover 66.

[0160] Specifically, by setting multiple latches 67, the connection strength between the top plate and the tank body 65 can be improved.

[0161] Along the circumferential direction of the top cover 66, the multiple latches 67 can be spaced at equal intervals or at unequal intervals.

[0162] In addition, the number of latches 67 can be two, three, four, five, six, seven, eight, etc.

[0163] In some embodiments of this application, such as Figure 4 and Figure 5 As shown, the slurry tank 60 also includes a sealing element 68, which is disposed between the top cover 66 and the tank body 65.

[0164] Specifically, by setting the sealing element 68, the sealing performance of the slurry tank 60 can be improved, further reducing the adverse effects of external air on the slurry.

[0165] In some embodiments of this application, such as Figure 4 and Figure 5As shown, the sealing element 68 is a sealing ring, with a raised ring 651 on the outer side of the top opening. The sealing ring has an annular groove 681, and the raised ring 651 and the annular groove 681 are in a concave-convex fit. This design increases the sealing path, thereby improving the sealing performance between the top cover 66 and the tank body 65.

[0166] It should be noted that the sealing ring can be either a rubber ring or a silicone ring. When the sealing ring is a rubber ring, the specific material can be one of NBR nitrile rubber, HNBR hydrogenated nitrile rubber, FLS fluorosilicone rubber, EPDM ethylene propylene diene monomer rubber, CR chloroprene rubber, or PU polyurethane rubber.

[0167] In some embodiments of this application, such as Figure 4 As shown, the slurry tank 60 also includes a pressure relief mechanism, which is located on the top cover 66.

[0168] Specifically, a pressure relief mechanism is provided on the top cover 66. The pressure relief mechanism can balance the pressure difference inside and outside the slurry tank 60 so that the discharge valve 30 can discharge the slurry.

[0169] It should be noted that the pressure relief mechanism can be a pressure relief valve or a pressure relief plug 69, etc.

[0170] In some embodiments of this application, such as Figure 4 As shown, the top cover 66 is provided with a pressure relief hole 661, and the slurry tank 60 also includes a pressure relief plug 69. The pressure relief plug 69 and the pressure relief hole 661 constitute a pressure relief mechanism. The pressure relief plug 69 is detachably connected to the top cover 66 and seals the pressure relief hole 661.

[0171] Specifically, the pressure relief plug 69 and the pressure relief hole 661 together constitute the pressure relief mechanism, which simplifies the structure of the pressure relief mechanism and thus effectively reduces the manufacturing cost.

[0172] It should be noted that a sealing ring 690 is provided on the pressure relief plug 69 or the pressure relief hole 661 to improve the sealing effect of the pressure relief plug 69. The material of the pressure relief ring is one of NBR nitrile rubber, HNBR hydrogenated nitrile rubber, FLS fluorosilicone rubber, EPDM ethylene propylene diene monomer rubber, CR neoprene rubber, and PU polyurethane rubber.
