Description

Technical Field

[0001] This invention relates to the technical field of battery production equipment, and more specifically, to a high-voltage homogenizer and a battery production line. Background Technology

[0002] A high-pressure homogenizer is a general-purpose device for preparing ultrafine liquid-liquid emulsions or liquid-solid dispersions. It is widely used in production and research across various industries, including food, chemical, pharmaceutical, light industry, and bioengineering. The high-pressure homogenizer mainly consists of a high-pressure pump, a homogenizing valve, a transmission mechanism, a motor, and a housing. The motor drives the high-pressure pump through the transmission mechanism, which in turn drives the homogenizing valve. Material processing takes place within the homogenizing valve. Under high pressure, the material enters the regulating gap of the homogenizing valve and achieves extremely high flow rates, creating a significant pressure drop. Through cavitation, turbulence, and shearing, the initially coarse emulsion or suspension is transformed into an extremely fine, uniform, and stable liquid-liquid emulsion or liquid-solid dispersion.

[0003] Chinese utility model patent CN112371030A discloses a high-pressure homogenizer, including a machine body, a storage tank, and a conveying pipeline. A conveying pump, a pressure stabilizing chamber, and a homogenizing valve are all contained within the machine body. The storage tank, conveying pump, pressure stabilizing chamber, and homogenizing valve are sequentially connected via the conveying pipeline. It also includes a transfer tank, with the conveying pipeline connecting the discharge end of the homogenizing valve to the transfer tank. The transfer tank is connected to the storage tank via the conveying pipeline. Through cyclic homogenization, the desired homogenization effect is achieved, thus realizing thorough homogenization of the material.

[0004] The aforementioned high-pressure homogenizer employs multiple homogenization processes to ensure homogenization effectiveness. In actual production, before the materials are mixed and loaded into the storage tank, pretreatment is often required to mix and stir them, resulting in a relatively stable slurry for further processing in the homogenizing valve. However, existing pretreatment devices simply mix the materials, and the materials in the slurry, due to differences in density and mass, easily separate, affecting subsequent homogenization efficiency and even causing blockage of the homogenizing valve, thus shortening its service life.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to its embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of protection of the invention.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] In this invention, the terms "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0023] On the one hand, such as Figure 1 and Figure 2 , Figure 3 As shown, a high-pressure homogenizer according to one embodiment of the present invention includes: The high-pressure pump component 1 is provided with a pump material inlet 101 and a pump material outlet 102; The first pretreatment component 2 includes a first tank 21 with a vertical circular cavity, a first stirring assembly 22, and a first driving assembly 23. The first stirring assembly 22 includes a rotating shaft 221 rotatably connected to the vertical circular cavity and a first baffle unit 222 disposed on the rotating shaft 221. The first baffle unit 222 includes a stirring slant frame surrounding the rotating shaft 221. The first driving assembly 23 is used to drive the rotating shaft 221 to rotate. The first tank 21 is provided with a material inlet 201 and a transfer outlet 202 at the bottom. The second pretreatment component 3 includes a second tank 31 with a horizontal circular cavity, a second stirring assembly 32, and a second driving assembly 33. The second stirring assembly 32 includes a second baffle unit 321 disposed in the horizontal circular cavity. The second driving assembly 33 is used to drive the second baffle unit 321 to rotate. The second tank 31 is provided with a transfer inlet 301 communicating with the transfer outlet and a material outlet 302 communicating with the pump material inlet 101.

[0024] The aforementioned high-pressure homogenizer, by setting a first tank 21 with a vertical circular cavity and a second tank 31 with a horizontal circular cavity, uses a first drive assembly 23 to drive a first stirring assembly 22 to stir the materials in the slurry in a first direction, and uses a second drive assembly 33 to drive a second stirring assembly 32 to stir the materials in the slurry in a second direction. This avoids the materials in the slurry from separating due to differences in density and mass, improves the uniformity of the slurry before homogenization, and facilitates improved homogenization efficiency in the subsequent process.

[0025] In one embodiment, the first tank 21 has a conical discharge section at its bottom, and the transfer outlet 202 is located at the bottom end of the conical discharge section; the first stirring assembly 22 includes a first stirring frame 223 located below the stirring slant frame, and the first stirring frame 223 is adapted to the conical discharge section. Thus, the conical discharge section facilitates the concentration of the stirred slurry to the transfer outlet 202, while the rotation of the first stirring frame 223 compresses the slurry and accelerates its flow rate from the transfer outlet 202.

[0026] In one embodiment, the first stirring assembly 22 further includes a second stirring frame 224 disposed above the first stirring frame 223. The inner wall of the horizontal circular cavity is provided with a baffle circular edge 203 adapted to the bottom of the stirring inclined frame, and the outer edge of the second stirring frame 224 is recessed into the outer edge of the first stirring frame 223. During the stirring process, the slurry is easily thrown against the tank wall due to the centrifugal force of rotation. By using the baffle circular edge 203 to block the slurry, it is concentrated back onto the second stirring frame 224, thereby ensuring stirring efficiency.

[0027] In one specific embodiment, the horizontal circular cavity is a frustum cavity, and the second stirring assembly 32 includes a frustum arc plate disposed within the frustum cavity; the transfer inlet 301 is disposed at the narrow end of the frustum cavity, and the material outlet 302 is disposed at the wide end of the frustum cavity. Thus, the slurry, under the action of gravity, slowly flows from the narrow end of the frustum cavity to the wide end, and finally leaves the frustum cavity from the material outlet 302.

[0028] In one specific embodiment, the first baffle unit 222, the first stirring frame 223, and the second stirring frame 224 are an integral structure, and the outer edges of the first baffle unit 222, the first stirring frame 223, and the second stirring frame 224 are made of the same stainless steel strip. This strengthens the overall structural strength of the first stirring assembly 22 and improves its service life.

[0029] On the other hand, such as Figure 4 , Figure 5 , Figure 9 , Figure 10 As shown, a battery production line according to one embodiment of the present invention includes a single-walled carbon nanotube production equipment 4, a high-pressure homogenizer 5, and a battery processing equipment 6; the single-walled carbon nanotube production equipment 4 is used to produce single-walled carbon nanotubes and transport them to the material inlet 201 of the first tank 21; the high-pressure homogenizer 5 homogenizes the slurry to obtain a homogenized slurry; the battery processing equipment 6 includes a coating machine 61 and a blower dryer 62, the coating machine 61 is used to coat the homogenized slurry onto a substrate to obtain a battery substrate, and the blower dryer 62 is used to dry the battery substrate. Thus, single-walled carbon nanotubes are produced by the single-walled carbon nanotube production equipment 4 and transported to the material inlet 201 of the first tank 21. After the single-walled carbon nanotubes are mixed with other materials and enter the material inlet 201, the high-pressure homogenizer 5 homogenizes the slurry to obtain a homogenized slurry. The coating machine 61 coats the homogenized slurry onto the substrate to obtain the battery substrate. The blower dryer 62 dries the battery substrate.

[0030] like Figure 5 and Figure 6As shown, in one embodiment, the single-walled carbon nanotube production equipment 4 includes an oxidation treatment device 7; the oxidation treatment device 7 includes a reactor 71 and a drive mechanism 72. The reactor 71 includes an outer furnace cylinder 73 with an inner cavity space and an inner spiral cylinder 74 disposed in the inner cavity space. The outer furnace cylinder 73 has an inner spiral groove, and the inner spiral cylinder has an outer threaded flange. A reaction chamber for generating carbon nanotubes is formed between the outer threaded flange and the inner spiral groove. The drive mechanism 72 includes a first transmission component 721 for driving the outer furnace cylinder 73 to rotate and a second transmission component 722 for driving the inner spiral cylinder 74 to rotate. Single-walled carbon nanotubes, as one-dimensional nanomaterials, are lightweight, have a perfectly connected hexagonal structure, and possess many exceptional mechanical, electrical, and chemical properties. Thus, single-walled carbon nanotubes are produced using chemical vapor deposition (CVD). In a high-temperature reactor, carbon-containing gas decomposes and catalyzes on the surface of metal catalyst nanoparticles, causing carbon atoms to dissolve and precipitate, growing into single-walled carbon nanotubes. When carbon-containing gas catalyzes the formation of single-walled carbon nanotubes on the surface of nanoparticles in the reaction chamber, the outer furnace cylinder 73 is driven to rotate by the first transmission component 721. The outer threaded flange and the inner spiral groove move synchronously or have a small relative displacement. The nanomaterial can move with the inner spiral groove of the outer furnace cylinder 73, thereby conveying the nanoparticles. This prevents the nanoparticles from adhering to the furnace wall for a long time and avoiding them from stacking together. It ensures sufficient contact area between the nanoparticles and the carbon-containing gas, improves the production efficiency and quality of single-walled carbon nanotubes.

[0031] Specifically, because nanomaterials are very fine and have a certain viscosity, during the preparation process, nanomaterials may adhere to the furnace wall. After the nanomaterials adhere to the furnace wall, the contact area between adjacent and stacked nanomaterials and carbon-containing gas is reduced, which affects the production efficiency of single-walled carbon nanotubes. At the same time, it may also cause multiple single-walled carbon nanotubes to stick together and form irregular carbon nanotubes, which affects the production quality and results in a high defect rate.

[0032] In one specific embodiment, the second transmission assembly 722 includes a transmission motor and a transmission unit, a transmission shaft, and an inner spiral cylinder 74 connected to the transmission shaft via a spline structure. The transmission motor drives the transmission shaft through the transmission unit, thereby causing the inner spiral cylinder 74 to rotate. The transmission unit is a transmission belt unit or a transmission chain unit.

[0033] In one specific embodiment, the drive mechanism 72 further includes an adjustment unit for adjusting the relative position of the inner spiral cylinder 74 to the furnace 71. Specifically, the adjustment unit is a threaded screw connection or a worm gear connection, and the position of the inner spiral cylinder 74 relative to the outer furnace cylinder 73 is adjusted by rotating the adjustment unit. Thus, by adjusting the position of the inner spiral cylinder 74 relative to the outer furnace cylinder 73, the gap size of the reaction chamber can be adjusted according to the nanoparticles and the planned production of single-walled carbon nanotubes, thereby facilitating the improvement of the production quality of single-walled carbon nanotubes.

[0034] In one specific embodiment, the outer furnace cylinder 73 and the inner spiral cylinder 74 rotate at the same speed, so that the gap size of the reaction chamber remains unchanged when conveying nanoparticles.

[0035] like Figure 7 and Figure 8 As shown, in one embodiment, the single-walled carbon nanotube production equipment 4 further includes a feeding device 8, which includes a feeding cylinder 81, a first pushing component 82, and an inflation component. The feeding cylinder 81 has a first cavity at its center and a second cavity communicating with the first cavity. The cylinder wall of the feeding cylinder 81 has a first inlet 801 communicating with the first cavity, a first outlet 802 communicating with the second cavity, and a venting unit 803 communicating with the inflation component. Nanoparticles enter the first cavity from the first inlet 801, the first pushing component 82 pushes the nanoparticles from the first cavity to the second cavity, and the inflation component inflates the second cavity. In this way, the material is conveyed to the first feed port 801, and the material enters the first cavity from the first feed port 801. The first pusher component 82 pushes the material from the first cavity to the second cavity. The gas filling component fills the second cavity with carbon-containing gas, so that the nanoparticles are isolated from the outside air before entering the reactor cavity, which facilitates the improvement of conveying efficiency and thus improves production efficiency.

[0036] In one embodiment, the single-walled carbon nanotube production equipment 4 further includes a conveying device 9; the conveying device 9 includes a hopper component 91 and a spiral conveying component 92, the spiral conveying component 92 including an inclined conveying pipe 93, a spiral rod 94 disposed within the conveying pipe 93, and a conveying motor 95 driving the spiral rod 94 to rotate; the top of the conveying pipe 93 has a pipe outlet, and the bottom has a pipe inlet communicating with the hopper component 91, the pipe outlet communicating with the material inlet 201. Thus, by pouring single-walled carbon nanotubes and other materials into the hopper component 91, the conveying motor 95 drives the spiral rod 94 to rotate, thereby causing the single-walled carbon nanotubes and other materials to move upward along the conveying pipe 93, while mixing during the movement.

[0037] Specifically, the single-walled carbon nanotubes are poured into the hopper component 91 and then undergo an acid washing and purification process.

[0038] like Figure 9 and Figure 10 As shown, in one embodiment, the coating machine 61 includes a coating frame 611, a moving part 612 disposed on the coating frame 611, and a coating part 613. The coating part 613 includes a coating nozzle and a pumping part for pumping homogeneous slurry to the coating nozzle. The moving part 612 is used to drive the coating nozzle to move along a first horizontal direction and a second horizontal direction, which are perpendicular to each other. The blower dryer 62 includes a drying frame 621, a feeding channel 622 disposed on the drying frame 621, and a blower drying part 623. The blower drying part 623 achieves the drying effect by blowing flowing gas into the feeding channel 622. Thus, the pumping component pumps the homogeneous slurry to the coating nozzle, and the moving component 612 drives the coating nozzle to move along the first horizontal direction and the second horizontal direction, thereby uniformly distributing the homogeneous slurry on the substrate and obtaining the battery substrate. After the battery substrate moves to the feeding channel, the blowing drying component 623 blows in flowing gas to dry the homogeneous slurry on the battery substrate.

[0039] In one embodiment, the battery processing equipment 6 further includes a loading / unloading device 63 disposed between the coating machine 61 and the blower dryer 62; the blower dryer 62 further includes a feeding component for conveying the battery substrate from the inlet of the feeding channel to the outlet; the loading / unloading device 63 includes a loading component 631 and an unloading component 632, the loading component 631 for moving the battery substrate from the coating machine to the channel inlet, and the unloading component 632 for transferring the battery substrate from the outlet. Thus, by moving the battery substrate from the coating machine to the channel inlet using the loading component 631, conveying the battery substrate from the inlet of the feeding channel to the outlet using the feeding component, and transferring the battery substrate from the outlet using the unloading component 632, the coating and drying processes are automated.

[0040] In one embodiment, the high-pressure homogenizer 5 further includes a cooling device 51; the high-pressure pump component 1 includes a pump body 13 with a pumping channel and a plunger component 14 disposed within the pump body 13; the cooling device 51 includes a first cooling component 52, which includes a cooling structure 53 disposed on the pump body 13 and a driving assembly 54. The driving assembly 54 is used to deliver cooling liquid to the cooling structure 53, and the cooling structure 53 is a cooling channel disposed outside the pumping channel. Thus, by delivering cooling liquid to the cooling structure 53 through the driving assembly 54, the plunger component 14 is prevented from operating at high temperatures, thereby improving the service life of the high-pressure pump component 1.

[0041] In one embodiment, the cooling structure 53 is a cooling channel located outside the pumping channel. Specifically, the cooling channel is not connected to the pumping channel. The cooling channel can be a machined channel on the pump body 13 or an externally installed bent pipe.

[0042] like Figure 11 As shown, in one embodiment, the cooling device 51 further includes a heat exchange component; the heat exchange component includes a water storage tank (not shown in the figure) connected by pipes, a conversion assembly, and a water pump unit (not shown in the figure). The conversion assembly includes a water circulation unit and a heat exchange unit disposed outside the water circulation unit. The water circulation unit has a first water inlet 501 connected to the cooling structure 53 and a second water inlet 502 connected to the driving assembly 54. The heat exchange unit has a third water inlet 503 and a fourth water inlet 504 connected to the water storage tank. Specifically, the heat exchange unit includes a heat exchange shell, and the water circulation unit has a plurality of heat exchange tubes passing through the heat exchange shell, the heat exchange tubes connecting the first water inlet 501 and the second water inlet 502. In this way, the cooling liquid is pumped to the cooling structure 53 on the pump body 13 by the water pump unit. The cooling liquid carries away the heat on the pump body 13. When passing through the water circulation unit, the heat exchange tube wall transfers the heat in the cooling liquid to the water in the heat exchange unit, and is pumped back to the water storage tank with the water, thereby converting the heat of the pump body 13 into the water stored in the water storage tank.

[0043] like Figure 12 and Figure 13 As shown, in one embodiment, the coating machine 61 further includes a roller pressing component 64 disposed at the outlet end of the coating machine frame 611. The roller pressing component 64 includes a first coating roller 641 driven by a first motor and a second equalizing roller 642 driven by a second motor. A material equalization gap is provided between the outer edge of the second equalizing roller 642 and the outer edge of the first coating roller 641. The first coating roller 641 is in close contact with the upper surface of the battery substrate to perform the coating action. Because the amount of material discharged from the middle and sides of the nozzle is different when the coating component 613 sprays the homogeneous slurry onto the substrate, the homogeneous slurry on the battery substrate is also different. Thus, when the conveyor belt of the coating machine 61 transports the battery substrate to the next process, the first coating roller 641 is in close contact with the upper surface of the battery substrate and rolls the uneven coating layer on the surface of the battery substrate to make it uniform, ensuring that the homogeneous slurry on the battery substrate is evenly distributed. At the same time, the first coating roller 641 is in contact with the homogeneous slurry and easily picks up the homogeneous slurry. The second equalizing roller 642 contacts and picks up the homogeneous slurry that is larger than the size of the equalizing gap, thereby ensuring that the outer edge of the first coating roller 641 is kept at the preset size.

[0044] Specifically, the oxidation treatment device 7 of the single-walled carbon nanotube production equipment 4 produces single-walled carbon nanotubes with stable structure and size. The high-pressure homogenizer 5 fully stirs and homogenizes the slurry containing single-walled carbon nanotubes to obtain a stable homogeneous slurry. At the same time, the roller pressing component 64 is used to ensure the thickness of the slurry layer of the battery substrate. The final conductivity of the battery substrate is guaranteed from three dimensions: the particle size of the raw materials of the battery electrolyte layer, the uniformity of the electrolyte layer composition distribution, and the overall thickness of the electrolyte layer.

[0045] In one embodiment, the roller pressing component 64 further includes a lifting assembly for driving the first coating roller 641 to perform lifting and lowering actions. The lifting assembly includes two lifting units respectively disposed on both sides of the first coating roller 641. The lifting units are used to lift the first coating roller 641. Specifically, the lifting unit includes a worm gear lifting platform and a lifting platform disposed at the output end of the worm gear lifting platform, and the first coating roller 641 is disposed on the lifting platform.

[0046] In one embodiment, the roller pressing component 64 further includes a scraping unit 643; the scraping unit 643 includes a scraper disposed on the outer diameter surface of the second equalizing roller 642, the scraper blade of the scraper being tangent to the outer diameter surface of the second equalizing roller 642. Since a portion of homogeneous slurry will remain on the surface of the second equalizing roller 642 and easily accumulates, by adjusting the equalization gap between the second equalizing roller 642 and the first coating roller 641, when the accumulated slurry thickness in a certain area of ​​the outer diameter surface of the first coating roller 641 is greater than the equalization gap, the excess slurry on the first coating roller 641 will be rolled away by the second equalizing roller 642. Through the rotation of the second equalizing roller 642, the homogeneous residue is scraped from the outer diameter surface of the second equalizing roller 642 and left on the scraper blade. The side of the scraper blade facing the second equalizing roller 642 forms a collection space with the outer diameter surface of the second equalizing roller 642, which can accumulate a certain amount of homogeneous residue.
