A breather valve 114 can also be provided on the first storage tank 11 and the second storage tank 21.

[0049] In order to achieve static mixing, in a specific embodiment, referring to Figure 4 As shown, the first static mixer 5 and the second static mixer 6 each include a housing 51, a first spiral blade 52 and a second spiral blade 53. The housing 51 includes a dispersed phase inlet 511, a mixing flow channel 512 and a dispersed phase outlet 513 from one end to the other. The first spiral blade 52 spirals clockwise around the mixing flow channel 512 in the housing 51, and the second spiral blade 53 spirals counterclockwise around the mixing flow channel 512 in the housing 51. The first spiral blade 52 and the second spiral blade 53 are alternately arranged along the mixing flow channel 512. This arrangement can guide the fluid to undergo multiple divisions, rotations and reorganizations in the flow channel, thereby achieving efficient mixing. The alternately arranged first spiral blade 52 and second spiral blade 53 along the mixing flow channel 512 can further enhance the mixing effect and prevent the formation of dead zones or short circuits in the flow channel.

[0050] In order to further improve the mixing effect, in some embodiments, referring to Figure 5 As shown, a plurality of flow-through holes 54 are provided on the first spiral blade 52 and the second spiral blade 53, and the flow-through holes 54 extend towards the dispersed phase outlet 513 end with a guide channel 55. The arrangement of multiple flow-through holes 54 can ensure that the raw materials are evenly distributed between the spiral blades, preventing local over-concentration or under-concentration. The guide channel 55 is the part of the flow-through hole 54 extending towards the dispersed phase outlet 513 end. The flow-through hole 54 and the guide channel 55 together constitute the flow path of the fluid between the spiral blades. Part of the fluid will pass through the flow-through hole 54, and part of the fluid will be hindered and guided by the spiral blade, changing its direction and speed. The purpose is to guide the fluid to flow more complexly between the spiral blades, thereby improving the mixing efficiency.

[0051] Further alternatively, referring to Figure 5 、 Figure 6 illustrated, the guide channel 55 is provided with alternating left spiral mixing blades 551 and right spiral mixing blades, which can further improve the mixing effect by re-segmenting, rotating, and recombining the fluid entering the guide channel 55 from the flow passage 54, and can save the total length of the mixing flow channel 512 to achieve better mixing effect in limited length. In another embodiment, referring to Figure 5 、 Figure 7 illustrated, the left spiral mixing blades 551 and the right spiral mixing blades can be replaced by fins 553 staggered in the guide channel 55, the fins 553 are provided through the side wall of the guide channel 55, the side wall of the guide channel 55 and the fins 553 on one side of the dispersed phase inlet 511 form a sputtering hole 554, the sputtering hole 554 is in communication with the mixing flow channel 512, the fins 553 are provided through the side wall of the guide channel 55, forming a staggered structure. This design not only increases the complexity and surface area of the guide channel 55, but also provides additional mixing opportunities. The sputtering hole 554 allows fluid to pass from the mixing flow channel 512 and undergoes sputtering and collision, thereby further promoting mixing; the presence of the sputtering hole 554 enables fluid to enter the guide channel 55 from the mixing flow channel 512 under the guidance of the fins 553, and undergoes intense turbulence and mixing during sputtering. When the fluid passes through the sputtering hole 554, it will be hindered and guided by the fins 553, resulting in a change in direction and an increase in speed, thereby increasing the mutual collision and shear force between the fluids. This sputtering and collision action helps to break up clumps and layers in the fluid, making the fluid more evenly distributed in the guide channel 55.

[0052] In summary, the static mixing material and raw material conveying system provided by the present application has the following technical effects:

[0053] 1. By introducing a static mixer, the system utilizes the fluid's own flow energy to achieve efficient mixing without relying on external power sources such as stirring paddles or mixers. This feature significantly reduces electricity consumption, making the entire production process more energy-efficient. The static mixer is divided into a first static mixer 5 and a second static mixer 6, which can achieve secondary mixing and more uniform mixing, avoiding problems such as local concentration unevenness or material layering that may occur with traditional stirring equipment. This helps to improve the quality and consistency of the final product, meeting more stringent quality control requirements;

[0054] 2. The static mixer has a simple structure and does not contain easily damaged parts such as blades or bearings of a mixer. Therefore, compared with traditional stirring equipment, the static mixer has lower maintenance costs and a simplified maintenance process. This not only reduces equipment downtime but also improves the overall stability and reliability of the production line;

[0055] 3. The system adopts a modular design, so that the system can be flexibly configured and expanded according to production needs, improving production efficiency;

[0056] 4. Since the static mixer does not rely on an external power source for stirring, the risk of introducing impurities due to wear and tear or failure of the stirring equipment is reduced. This helps to maintain the cleanliness of the production environment, further ensuring product quality; reducing energy consumption and equipment maintenance costs not only helps to reduce production costs, but also meets the current trend of environmental friendliness and sustainable development.
