[0002] In the sponge material manufacturing industry, the uniformity of raw material mixing is critical to the performance and quality of the final product. Traditional sponge material mixing systems usually use stirring equipment, such as stirring paddles or stirrers, to drive fluid movement through mechanical force to achieve uniform mixing between different components. However, this mixing method has problems such as high energy consumption, complex equipment maintenance, limited mixing efficiency, and the possibility of introducing impurities. Summary of the invention
[0003] In order to overcome at least one of the defects of the prior art, the present invention provides a static mixing batching and raw material delivery system. The system can overcome the limitations of the traditional mixing system, utilize the flow energy of the fluid itself, and achieve efficient mixing effect without the need for an external power source. This system not only reduces power consumption and equipment costs, but also simplifies the equipment maintenance process and improves production efficiency.
[0004] The technical solution adopted by the present invention to solve the problem is:
[0005] A static mixing batching and raw material conveying system, comprising: a first material conveying processing module, the first material conveying processing module comprising a first storage tank, a first mixing tank, a first intermediate tank and a first foaming machine working tank connected in sequence; a second material conveying module, the second material conveying module comprising a second storage tank and a second mixing tank connected in sequence, the second mixing tank being communicated with the first intermediate tank; a third material conveying processing module, the third material conveying processing module comprising a third storage tank, a third intermediate tank and a third foaming machine working tank connected in sequence; a temperature control module, the temperature control module comprising a hot and cold all-in-one machine and a plurality of heat exchangers connected thereto, the heat exchangers being respectively connected to the first material conveying processing module, the second material conveying module and the third material conveying processing module, for controlling the mixing temperature; wherein a first static mixer is arranged between the first mixing tank and the first intermediate tank, and a second static mixer is arranged between the second mixing tank and the first intermediate tank.
[0006] By adopting the above solution and introducing a static mixer, the system can achieve efficient mixing without an external power source, thereby significantly reducing electricity consumption; the static mixer has a simple structure and no wearing parts, and its maintenance cost is lower and the maintenance process is simpler than traditional mixing equipment; the system adopts a modular design, including multiple material conveying and processing modules and temperature control modules, which facilitates flexible configuration and expansion, thereby improving production efficiency.
[0007] Furthermore, the first static mixer and the second static mixer both include: a shell, the shell including a dispersed phase inlet, a mixing channel and a dispersed phase outlet in sequence from one end to the other end; a first rotor, the first rotor is spirally wound clockwise in the mixing channel in the shell; a second rotor, the second rotor is spirally wound counterclockwise in the mixing channel in the shell; wherein the first rotor and the second rotor are alternately arranged along the mixing channel.
[0008] By adopting the above scheme, the fluid can be guided to undergo multiple divisions, rotations and reorganizations in the flow channel, thereby achieving an efficient mixing effect; the first rotor and the second rotor are alternately arranged along the mixing flow channel, which can further enhance the mixing effect and avoid the formation of dead zones or short circuits in the flow channel.
[0009] Furthermore, a plurality of flow holes are provided on the first rotating vane and the second rotating vane, and a guide channel is extended from the flow hole toward one end of the dispersed phase outlet.
[0010] By adopting the above scheme, the setting of multiple flow holes can ensure that the raw materials are evenly distributed between the rotors, avoiding local concentrations that are too high or too low; the guide channel is the part of the flow hole that extends to one end of the dispersed phase outlet. The flow hole and the guide channel together constitute the flow path of the fluid between the rotors. Part of the fluid will pass through the flow hole, and part of the fluid will be blocked and guided by the rotor, causing changes in direction and speed. The purpose is to guide the fluid to flow more complexly between the rotors, thereby improving the mixing efficiency.
[0011] Furthermore, the guide channel is provided with alternating left-hand spiral mixing sheets and right-hand spiral mixing sheets.
[0012] By adopting the above scheme, the fluid entering the guide channel from the flow hole can be divided, rotated and reorganized again, further improving the mixing effect, saving the total length of the mixing channel, and achieving a better mixing effect within a limited length.
[0013] Furthermore, staggered fins are provided in the guide channel, the fins penetrate the side wall of the guide channel, a sputtering hole is formed between the side of the fin facing the dispersed phase inlet and the side wall of the guide channel, and the sputtering hole is connected to the mixing channel.
[0014] By adopting the above scheme, the fins are arranged on the side wall of the guide channel to form a staggered structure. This design not only increases the complexity and surface area of the guide channel, but also provides additional mixing opportunities. The sputtering holes allow the fluid to pass through the mixing channel and cause sputtering and collision, thereby further promoting mixing. The presence of the sputtering holes allows the fluid to enter the guide channel from the mixing channel under the guidance of the fins, and violent turbulence and mixing occur during the sputtering process. When the fluid passes through the sputtering holes, it will be hindered and guided by the fins, causing a change in direction and an increase in speed, thereby increasing the mutual collision and shear force between the fluids. This sputtering and collision effect helps to break up the clumps and stratification in the fluid, so that the fluid is more evenly distributed in the guide channel.

The first temperature control loop and the second temperature control loop are designed to control the temperature of the raw materials in the storage tank to ensure that they are kept within the appropriate temperature range during storage and transportation.
[0017] Furthermore, the first material delivery channel and the second material delivery channel both include a manual ball valve, a filter, a discharge pump, a safety overflow valve, a one-way valve, a pressure gauge and a pneumatic ball valve; the first temperature control circuit and the second temperature control circuit both include a filter, a material transfer pump, a safety overflow valve, a manual ball valve, a one-way valve, a pressure gauge, a heat exchange device and a mold temperature controller.
[0018] By adopting the above solution, the feed channel and temperature control circuit both include various equipment required for the complete process from raw material input to finished product output, ensuring the continuity and stability of the production process; the installation of safety devices such as safety relief valves and pressure gauges effectively reduces the risks that may occur in the production process; the combination of manual ball valves and pneumatic ball valves not only ensures rapid response capabilities in emergency situations, but also meets the needs of automated production lines; the reasonable selection and configuration of equipment such as filters and transfer pumps ensure the smooth flow of materials and temperature control media, and improve production efficiency.
[0019] Furthermore, the first mixing tank is provided with a first mixing outlet, the second mixing tank is provided with a second mixing outlet, a first feeding pipe is provided between the first mixing outlet and the first intermediate tank and the first foaming machine working tank, and the first static mixer is provided on the first feeding pipe; a second feeding pipe is provided between the second mixing outlet and the first intermediate tank and the first foaming machine working tank, and the second static mixer is provided on the second feeding pipe.
[0020] By adopting the above solution, through the design of two mixing tanks and one intermediate tank, the system can flexibly process a variety of materials to meet the production needs of different products; the use of static mixers significantly improves the mixing efficiency of materials and ensures the uniformity and stability of materials before foaming; the design of the entire system optimizes the process of material transmission and mixing, improves production efficiency and reduces production costs.
[0021] Furthermore, an auxiliary material replenishing pipeline is connected between the first mixing tank and the second mixing tank, and the auxiliary material replenishing pipeline includes a diaphragm pump and an auxiliary material tank.
[0022] By adopting the above solution, the design of the auxiliary material replenishment pipeline allows the system to flexibly adjust the type and amount of auxiliary materials according to production needs, thereby optimizing product performance; the use of diaphragm pumps reduces the risk of leakage and contamination, ensuring the safety and reliability of auxiliary material transportation.
[0023] Furthermore, the first storage tank, the first mixing tank, the second storage tank and the second mixing tank are all provided with electronic scales for weighing, and the first storage tank and the second storage tank are also provided with maximum liquid level indicators.
[0024] By adopting the above scheme, the main function of the electronic scale is to monitor and record the weight of the material in the storage tank or mixing tank in real time, which is essential for accurately controlling the material feeding amount, monitoring material consumption and ensuring product quality; the main function of the maximum liquid level indicator is to monitor the liquid level in the storage tank. When the liquid level reaches the preset maximum point, an alarm or signal will be issued to prevent material overflow or leakage; the design of the electronic scale and the maximum liquid level indicator emphasizes accuracy, ensuring accurate monitoring of material weight and liquid level. These devices are usually connected to the central control system to realize real-time data transmission and remote monitoring. This improves the automation and intelligence level of the system and reduces the difficulty and risk of manual operation.
[0025] In summary, the static mixing batching and raw material conveying system provided by the present invention has the following technical effects:
[0026] 1. By introducing a static mixer, the system uses the fluid's own flow energy to achieve efficient mixing without relying on external power sources such as a stirring paddle or agitator.

The static mixer is divided into a first static mixer and a second static mixer, which can achieve secondary mixing and achieve more uniform mixing, avoiding problems such as local uneven concentration or material stratification that may be caused by traditional mixing equipment. This helps to improve the quality and consistency of the final product and meet more stringent quality control requirements;
[0027] 2. The static mixer has a simple structure and does not contain wearing parts, such as agitator blades or bearings. Therefore, compared with traditional mixing equipment, the maintenance cost of the static mixer is lower and the maintenance process is more simplified. This not only reduces equipment downtime, but also improves the overall stability and reliability of the production line;
[0028] 3. The system adopts modular design, which allows the system to be flexibly configured and expanded according to production needs, thereby improving production efficiency;
[0029] 4. Since the static mixer does not rely on an external power source for stirring, the risk of introducing impurities due to wear or failure of the stirring equipment is reduced. This helps to maintain the cleanliness of the production environment and further ensure product quality; reducing energy consumption and reducing equipment maintenance costs not only helps to reduce production costs, but also conforms to the current trend of environmental friendliness and sustainable development.

[0050] In order to further improve the mixing effect, in some embodiments, refer to Figure 5 As shown, a plurality of flow holes 54 are provided on the first rotor 52 and the second rotor 53, and a guide channel 55 is extended from the flow hole 54 to one end of the dispersed phase outlet 513. The arrangement of the plurality of flow holes 54 can ensure that the raw materials are evenly distributed between the rotors to avoid excessively high or low local concentrations; the guide channel 55 is the portion of the flow hole 54 extending to one end of the dispersed phase outlet 513, and the flow holes 54 and the guide channel 55 together constitute a flow path of the fluid between the rotors. A portion of the fluid will pass through the flow holes 54, and a portion of the fluid will be blocked and guided by the rotors, causing changes in direction and speed, with the purpose of guiding the fluid to flow more complexly between the rotors, thereby improving the mixing efficiency.
[0051] For further optional information, see Figure 5 , Figure 6 As shown, the guide channel 55 is provided with left-hand spiral mixing sheets 551 and right-hand spiral mixing sheets arranged alternately, which can divide, rotate and reorganize the fluid entering the guide channel 55 from the flow hole 54, further improve the mixing effect, save the total length of the mixing channel 512, and achieve a better mixing effect within a limited length.

The presence of the sputtering holes 554 enables the fluid to enter the guide channel 55 from the mixing channel 512 under the guidance of the fins 553, and violent turbulence and mixing occur during the sputtering process. When the fluid passes through the sputtering holes 554, it will be obstructed and guided by the fins 553, causing a change in direction and an increase in speed, thereby increasing mutual collisions and shear forces between the fluids. This sputtering and collision effect helps to break up clumps and stratification in the fluid, allowing the fluid to be more evenly distributed in the guide channel 55.
[0052] In summary, the static mixing batching and raw material conveying system provided by the present invention has the following technical effects:
[0053] 1. By introducing a static mixer, the system uses the fluid's own flow energy to achieve efficient mixing without relying on an external power source, such as a stirring paddle or agitator. This feature significantly reduces power consumption, making the energy consumption of the entire production process more economical. The static mixer is divided into a first static mixer 5 and a second static mixer 6, which can achieve secondary mixing and achieve more uniform mixing, avoiding problems such as local uneven concentration or material stratification that may be caused by traditional mixing equipment. This helps to improve the quality and consistency of the final product and meet more stringent quality control requirements;
[0054] 2. The static mixer has a simple structure and does not contain wearing parts, such as agitator blades or bearings. Therefore, compared with traditional mixing equipment, the maintenance cost of the static mixer is lower and the maintenance process is more simplified. This not only reduces equipment downtime, but also improves the overall stability and reliability of the production line;
[0055] 3. The system adopts modular design, which allows the system to be flexibly configured and expanded according to production needs, thereby 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 or failure of the stirring equipment is reduced. This helps to maintain the cleanliness of the production environment and further ensure product quality; reducing energy consumption and reducing equipment maintenance costs not only helps to reduce production costs, but also conforms to the current trend of environmental friendliness and sustainable development.
[0057] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
