Description

Technical Field

[0001] This application relates to the technical field of resin production, and in particular to an automatic feeding production system for wind power resin. Background Technology

[0002] Currently, wind power resin production remains a crucial component in the field of chemical production equipment technology. With the booming development of the wind power industry, the market demand for wind power resin has increased dramatically, and its production efficiency directly impacts the development of the entire wind power industry chain. Highly efficient wind power resin production can not only meet the market's substantial demand for wind power equipment but also reduce production costs and enhance the market competitiveness of enterprises. However, current problems in the material feeding stage of wind power resin production severely restrict the improvement of overall production efficiency, becoming a critical issue that the industry urgently needs to address.

[0003] Currently, the industry mainstream adopts two feeding schemes. One is single-tank, single-reactor series feeding, where each raw material is equipped with a separate storage tank, and is sequentially fed into individual mixing vessels via pumps. This scheme has lower equipment investment costs, but when a raw material storage tank needs replenishment, the entire production line must be stopped, and high-viscosity resins flow very slowly in ambient temperature pipelines. The other is multi-tank alternating feeding, where some companies add spare storage tanks, allowing replenishment and feeding to alternate, reducing replenishment waiting time, but it cannot solve the efficiency loss caused by pipeline fluid resistance.

[0004] Therefore, there is a problem of reduced production efficiency in related technologies, and there is an urgent need for an automatic feeding production system for wind power resin. Summary of the Invention

[0005] To improve production efficiency, this application provides an automatic feeding production system for wind power resin.

[0006] This application provides an automatic feeding production system for wind power resin, which adopts the following technical solution: An automated resin feeding production system for wind power, comprising: The raw material storage module includes resin tank assembly, resin tank assembly, diluent tank assembly, and auxiliary agent tank assembly; The reaction module includes at least two stirred tanks, each stirred tank having two feed inlets, which allow two different raw materials to be fed into the same stirred tank simultaneously. The resin tank group, resin vessel group, diluent vessel group, and auxiliary agent vessel group are respectively connected to the feed inlet through the conveying module. Any one of the resin tank group, resin vessel group, diluent vessel group, and auxiliary agent vessel group can feed materials into multiple mixing tanks.

[0007] By adopting the above technical solution, the raw material storage module includes resin tanks, resin containers, diluent containers, and auxiliary agent containers, enabling the classified storage of different types of raw materials to meet the storage needs of various raw materials in wind power resin production. The reaction module is equipped with at least two stirred tanks, each with two feed inlets, allowing two different raw materials to be simultaneously fed into the same stirred tank. This enables synchronous input and mixing of different raw materials, improving mixing efficiency and production flexibility, and allowing for the simultaneous production of multiple formulations. The conveying module connects each container in the raw material storage module to the feed inlets of the stirred tanks, and each container can feed materials into multiple stirred tanks, ensuring that raw materials can be flexibly conveyed to different stirred tanks according to production needs. This achieves efficient material conveying and distribution, thereby improving the production efficiency and flexibility of the entire wind power resin automatic feeding production system.

[0008] Optionally, the conveying module includes a conveying pipeline and a power pump. The resin tank group, the resin container group, the diluent container group and the auxiliary agent container group are respectively connected to the feed inlet through the conveying pipeline. An automatic valve is provided on the conveying pipeline. The power pump is provided on the conveying pipeline. A large-angle elbow is provided at the corner of the conveying pipeline.

[0009] By adopting the above technical solution, each raw material tank group is connected to the feed inlet of the stirred tank via conveying pipelines, thus realizing the conveying of raw materials from the storage module to the reaction module. Automatic valves are installed on the conveying pipelines, allowing for flexible control of pipeline opening and closing as needed, facilitating precise control of the timing and quantity of raw material conveying. A power pump is installed on the conveying pipelines to provide power for the conveying of raw materials, ensuring smooth conveying despite pipeline resistance. Large-angle elbows are installed at the corners of the conveying pipelines. These large-angle elbows allow for smoother fluid flow at corners, reducing pressure loss compared to ordinary elbows, lowering energy consumption for conveying, and reducing wear on the pipelines, extending their service life. This improves the stability and efficiency of the entire conveying system, enabling more efficient and stable conveying of raw materials from the storage module to the stirred tank in the reaction module. Simultaneously, the large-angle elbows reduce the frequency of pump start-ups and shutdowns due to high pipeline flow resistance, lowering energy consumption and improving equipment utilization.

[0010] Optionally, the radius of curvature R of the large-angle elbow is ≥12D, where D is the nominal diameter of the large-angle elbow, and the surface roughness Ra of the inner wall of the large-angle elbow is ≤1.0μm.

[0011] By adopting the above technical solution, the large-angle elbow has a large radius of curvature and low surface roughness of the inner wall, which makes the fluid flow more smoothly in the pipeline, reduces the collision and friction between the fluid and the inner wall of the elbow, and thus reduces the pressure loss of the fluid.

[0012] Optionally, a heat transfer oil coil is provided on the outside of the conveying pipeline.

[0013] By adopting the above technical solution, the heat transfer oil coil can heat and insulate the conveying pipeline, keeping the resin within a certain temperature range. Since the viscosity of the resin decreases after heating to a certain temperature, the lower viscosity resin exhibits increased fluidity during transport within the pipeline, thereby reducing resistance and improving conveying efficiency. Simultaneously, the lower viscosity also reduces the pressure required for transport, thus decreasing energy consumption.

[0014] Optionally, the resin tank assembly includes at least two resin storage tanks, each resin storage tank having two discharge ports, each discharge port corresponding to two conveying pipes, and the two conveying pipes corresponding to the same discharge port being connected to a single mixing vessel.

[0015] By adopting the above technical solution, the resin tank assembly includes at least two resin storage tanks, each with two discharge ports, and each discharge port corresponds to two conveying pipes. The two conveying pipes corresponding to the same discharge port are connected to a single mixing vessel, allowing the resin tank assembly to simultaneously supply resin to multiple mixing vessels. The multiple resin storage tanks increase the resin reserve, ensuring continuous supply. The two discharge ports can discharge simultaneously, improving discharge efficiency. The two conveying pipes corresponding to the same discharge port can quickly transport resin to the mixing vessel, and the conveying volume and speed can be flexibly adjusted according to needs. Multiple mixing vessels can operate synchronously or asynchronously, improving production flexibility and efficiency, and meeting the production requirements of different formulations and outputs.

[0016] Optionally, the large-angle elbow can be replaced with a Venturi elbow.

[0017] By adopting the above technical solution, the large-angle elbow is replaced with a Venturi elbow. The Venturi elbow has a gradually narrowing and expanding structure. When the fluid passes through, it can accelerate in the contraction section and decelerate in the expansion section while maintaining low flow resistance. This change in flow pattern helps to reduce the energy loss of the fluid, while maintaining low flow resistance performance, ensuring the high efficiency of the resin in the transportation process, and further improving the transportation efficiency and space utilization of the entire wind power resin automatic feeding production system.

[0018] Optionally, it also includes a slow storage tank, a coaxial injection pipe, and a phase separator. The resin tank group, the slow storage tank, and the resin tank group are respectively connected to the coaxial injection pipe. The coaxial injection pipe is connected to the phase separator through the conveying module. The phase separator is connected to the slow storage tank and one of the feed ports. The diluent tank group and the auxiliary agent tank group are respectively connected to another feed port through the conveying module. The slow storage tank is used to store low-viscosity sheath fluid that is immiscible with the resin. The coaxial injection tube is used to encapsulate the resin with the sheath fluid and allow it to enter the delivery module. The phase separator is used to separate the resin and sheath fluid mixture, and the separated resin is sent into the stirring vessel, while the sheath fluid is transported back to the slow storage tank.

[0019] By adopting the above technical solution, a slow storage tank stores a low-viscosity sheath liquid that is immiscible with the resin. When the resin in the resin tank and resin vessel groups enters the coaxial injection pipe, the coaxial injection pipe allows the sheath liquid to encapsulate the resin before entering the conveying module. Because the sheath liquid has low viscosity and is immiscible with the resin, its encapsulation of the resin reduces friction between the resin and the inner wall of the conveying pipe, lowers conveying resistance, and improves resin conveying efficiency. Simultaneously, during conveying, the sheath liquid prevents the resin from directly contacting the inner wall of the pipe, reducing resin residue in the pipe and minimizing interference with subsequent resin components of different formulations. When the resin and sheath liquid mixture reaches the phase separator, the phase separator separates the two. The separated resin enters the stirred tank to participate in the reaction, while the sheath liquid is conveyed back to the slow storage tank, achieving the recycling of the sheath liquid, saving resources and costs, and ensuring the purity of the resin and the reaction effect. Meanwhile, the diluent tank group and the auxiliary agent tank group are connected to another inlet through the conveying module, enabling the separate conveying and addition of different raw materials. This facilitates flexible raw material formulation according to different formulations and supports rapid switching between multiple formulations.

[0020] Optionally, the coaxial injection tube includes an inner tube, an outer tube, and a nozzle. The outer tube is coaxially sleeved on the inner tube, and an annular delivery cavity is formed between the outer tube and the inner tube. The inner tube is connected to the resin tank group and the resin trough group respectively. The outer tube is connected to the slow storage tank. The nozzle is connected to the inner tube and the outer tube respectively, and the nozzle is connected to the phase separator through the delivery module.

[0021] By adopting the above technical solution, the inner tube of the coaxial injection pipe is connected to the resin tank assembly and resin trough assembly, while the outer tube is connected to the slow storage tank. The outer tube is coaxially sleeved on the inner tube to form an annular conveying cavity, and the nozzle is connected to both the inner and outer tubes and, through the conveying module, to the phase separator. During operation, the sheath fluid in the slow storage tank is conveyed to the outer tube, passes through the annular conveying cavity, and reaches the nozzle. After the sheath fluid flow stabilizes, the resin in the resin tank assembly and resin trough assembly is conveyed to the inner tube and enters the nozzle. In this way, the sheath fluid can encapsulate the resin and enter the conveying module. Because the sheath fluid is immiscible with the resin and has low viscosity, it can act as a lubricant between the resin and the inner wall of the pipe, reducing the resistance to resin transport within the pipe and facilitating resin transport.

[0022] Optionally, the outer tube has multiple tangential holes distributed around the axis of the outer tube. The tangential holes are opened along the circumferential tangent direction of the outer tube and are respectively connected to the annular conveying cavity and the slow storage tank.

[0023] By adopting the above technical solution, multiple tangential holes distributed along the circumferential direction around the axis of the outer tube allow the sheath fluid in the slow storage tank to enter the annular delivery chamber tangentially. This tangential entry method allows the sheath fluid to form a spiral flow path within the annular delivery chamber, thus more evenly wrapping around the resin being transported in the inner tube. This helps enhance the lubrication effect of the sheath fluid on the resin, reduces friction between the resin and the inner wall of the delivery pipe, thereby reducing delivery resistance, improving resin delivery efficiency, and better maintaining the low viscosity state of the resin during delivery, ensuring smooth resin delivery within the pipeline.

[0024] Optionally, the inner diameter of the outer tube gradually decreases along the direction of sheath fluid delivery.

[0025] By adopting the above technical solution, the inner diameter of the outer pipe gradually decreases along the direction of sheath fluid delivery. According to the principles of fluid mechanics, under the condition of a constant fluid flow rate, a smaller pipe cross-sectional area will increase the fluid velocity. Therefore, the sheath fluid will flow faster when passing through the outer pipe, reaching the nozzle more quickly. This results in a more stable and rapidly flowing sheath fluid layer within the pipe, allowing the sheath fluid to better encapsulate the resin, enhancing its lubrication, reducing frictional resistance between the resin and the inner wall of the pipe, and thus improving the resin delivery efficiency within the pipe. This further enhances the overall feeding efficiency of the wind power resin automatic feeding production system.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the cooperation of resin tank group, resin tank group, diluent tank group, auxiliary agent tank group, mixing tank and conveying module, different raw materials can be put into the system at the same time, avoiding the problems of waiting for raw material replenishment and waiting for feeding sequence in the traditional intermittent feeding method. This eliminates the queuing waiting time in the feeding process and realizes the parallel operation of raw material replenishment, feeding and mixing processes, thereby improving the overall production efficiency of the wind power resin automatic feeding production system. 2. The large-angle elbow design makes the fluid flow more smoothly in the pipeline, reducing the collision and friction between the fluid and the inner wall of the elbow, thereby reducing the pressure loss of the fluid. 3. Through the cooperation of the slow storage tank, coaxial injection pipe and phase separator, the sheath liquid can be used to encapsulate the resin during transportation, thereby reducing the friction between the resin and the inner wall of the pipe, reducing the transportation resistance, and thus improving the resin transportation efficiency.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses an automatic feeding production system for wind power resin.

[0034] It should be noted that, in the description of this invention, the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0035] Example 1: Refer to Figure 1 An automated wind power resin feeding production system includes a raw material storage module 1, a reaction module 2, and a conveying module 3. The raw material storage module 1 stores raw materials for resin production and is connected to the reaction module 2 via the conveying module 3 to facilitate the delivery of raw materials into the reaction module 2 for wind power resin production.

[0036] Specifically, the raw material storage module 1 includes a resin tank assembly 11, a resin container assembly 12, a diluent container assembly 13, and an auxiliary agent container assembly 14. The resin tank assembly 11 includes at least two resin storage tanks 111, which store liquid resin. The resin storage tanks 111 are typically made of corrosion-resistant metal materials, such as stainless steel, and have good sealing properties to prevent resin leakage and the introduction of external impurities.

[0037] In this embodiment, two resin storage tanks 111 are provided, which serve as backups for each other. The resin storage tanks 111 are provided with two discharge ports 112, which are generally circular and their size is designed according to actual production needs.

[0038] The resin storage tank 111 is a cylindrical structure made of 316L stainless steel with a wall thickness of 12mm and a capacity of 200-300 tons. The resin storage tank 111 is covered with a 50mm rock wool insulation layer and is equipped with an electromagnetic flow meter and ball valve combination device at the bottom for precise flow control.

[0039] Both resin storage tanks 111 can be connected to the external tank truck 4 via insulated pipes with a diameter of 150mm. A discharge pump 41 is installed on the insulated pipe to pump the resin preheated to 55-85℃ in the tank truck 4 into the designated resin storage tank 111.

[0040] The resin tank assembly 12, the diluent tank assembly 13, and the additive tank assembly 14 are all composed of multiple additive storage tanks 121. In this embodiment, the resin tank assembly 12 includes two additive storage tanks 121, the diluent tank assembly 13 includes three additive storage tanks 121, and the additive tank assembly 14 includes two additive storage tanks 121. In addition to the resin tank assembly 12, the diluent tank assembly 13, and the additive tank assembly 14, a spare additive storage tank 121 is also provided.

[0041] Resin tank group 12 is used to store special resin raw materials, diluent tank group 13 is used to store diluent, and auxiliary agent tank group 14 is used to store specific auxiliary agents for production, such as curing agents, accelerators or toughening agents, etc., which can be configured according to actual needs to meet the production needs of different formulations.

[0042] The tops of the eight additive storage tanks 121 are all connected to an external raw material replenishment device via pipes, so as to replenish raw materials into the eight additive storage tanks 121 respectively. Multiple additive storage tanks 121 in the same group serve as backups for each other. When the remaining amount in the additive storage tank 121 is less than 10%, the backup additive storage tank 121 is automatically switched to ensure the continuity of production.

[0043] The conveying module 3 includes a conveying pipe 31 and a power pump 32. There are multiple conveying pipes 31, which are respectively connected to the resin storage tank 111 and the additive storage tank 121. The material of the conveying pipes 31 is selected according to the characteristics of the conveyed raw materials and temperature conditions.

[0044] In this embodiment, the conveying pipes 31 corresponding to the three additive storage tanks 121 in the diluent tank group 13 are interconnected, so that the three additive storage tanks 121 in the diluent tank group 13 can share the conveying pipes 31, so as to avoid the failure of a single conveying line affecting the entire diluent conveying process, and ensure the stability and reliability of the system.

[0045] Each conveying pipe 31 is equipped with an automatic valve 33, which can automatically open or close according to the instructions of the control system to control the conveying volume and conveying time of the raw materials. The number of power pumps 32 is equal to the number of conveying pipes 31 and is set one-to-one, used to pump the raw materials out of different resin storage tanks 111 and additive storage tanks 121 respectively. In this embodiment, the power pumps 32 are centrifugal pumps, providing power for the conveying of raw materials.

[0046] A large-angle elbow 34 is provided at the corner of the conveying pipeline 31. The radius of curvature R of the large-angle elbow 34 is ≥12D, where D is the nominal diameter of the large-angle elbow 34, and the surface roughness Ra of the inner wall of the large-angle elbow 34 is ≤1.0μm. In this embodiment, the radius of curvature of the large-angle elbow 34 is 12D, and the surface roughness Ra of the inner wall is 0.8μm.

[0047] The large-angle elbow 34 is manufactured using a molding process, which makes the inner wall smooth and reduces fluid resistance. As a result, the large-angle elbow 34 allows the fluid to flow more smoothly in the conveying pipeline 31, reducing the collision and friction between the fluid and the inner wall of the large-angle elbow 34, thereby reducing the pressure loss of the fluid.

[0048] In other embodiments, the large-angle elbow 34 can also be replaced with a Venturi elbow. The Venturi elbow has a gradually converging and expanding structure, which allows the fluid to accelerate in the contraction section and decelerate in the expansion section while maintaining low flow resistance. This flow pattern helps reduce energy loss while maintaining low flow resistance, ensuring high efficiency in resin transportation and further improving the overall conveying efficiency and space utilization of the wind power resin automatic feeding production system. Simultaneously, the Venturi elbow design saves 15% of installation space while maintaining low flow resistance.

[0049] A heat transfer oil coil 5 is arranged around the outside of the conveying pipeline 31. The heat transfer oil coil 5 can be made of seamless steel pipe, such as Φ25×2.5mm seamless steel pipe, with a working pressure of 1.6MPa. The circulating flow of heat transfer oil heats and keeps the raw material in the conveying pipeline 31 warm, maintaining the resin at a low viscosity state at a certain temperature for easy conveying. For example, when the resin is kept at a temperature of 55-85℃, its viscosity will decrease and the flow rate will increase. In this embodiment, heat transfer oil coils 5 are also provided on the resin storage tank 111 and the additive storage tank 121 to facilitate temperature control inside the resin storage tank 111 and the additive storage tank 121.

[0050] The reaction module 2 includes at least two stirred tanks 21. In this embodiment, three stirred tanks 21 are provided. The three stirred tanks 21 have the same structure, and one of the three stirred tanks 21 can be used as a backup for the other two stirred tanks 21. It is not started normally, or it can be used simultaneously with the other two stirred tanks 21.

[0051] The top of the mixing vessel 21 is provided with two feed inlets 211, which allow two different raw materials to be fed into the same mixing vessel 21 simultaneously. In this embodiment, multiple conveying pipes 31 intersect and connect with each other near the feed inlets 211, and each branch of the conveying pipes 31 is provided with an automatic valve 33 to control the flow path of the fluid in the conveying pipes 31, thereby achieving the effect that any resin storage tank 111 and any additive storage tank 121 can be fed into any feed inlet 211.

[0052] In this embodiment, each outlet 112 on the resin storage tank 111 corresponds to two conveying pipes 31, and the two conveying pipes 31 corresponding to the same outlet 112 are connected to the inlet 211 on the single mixing vessel 21. This allows the resin output from one outlet 112 to enter the same mixing vessel 21 via two different routes, realizing parallel multi-path resin conveying from the resin storage tank 111 to the single mixing vessel 21. This increases the resin conveying capacity, reduces the conveying time, and improves the conveying efficiency. At the same time, it avoids the impact of a single conveying line failure on the entire resin conveying process, ensuring the stability and reliability of the system.

[0053] Weight sensors 6 are installed on additive storage tank 121 and mixing vessel 21, respectively, and are electrically connected to automatic valve 33. Weight sensors 6 can monitor the weight changes of raw materials in additive storage tank 121 and mixing vessel 21 in real time. When the preset feeding amount is reached, weight sensor 6 transmits a signal to automatic valve 33, which closes and stops feeding, thereby accurately controlling the feeding amount and ensuring the accuracy of the production formula.

[0054] The implementation principle of this embodiment is as follows: When it is necessary to produce wind power resin, the resin preheated to 55-85°C in the tank truck 4 is first pumped into the designated resin storage tank 111 through the heat-insulated pipe using the unloading pump 41. At the same time, according to the preset formula, the corresponding power pump 32 and automatic valve 33 are started to transport the raw materials in the designated resin storage tank 111 and additive storage tank 121 to the stirring tank 21 through the conveying pipe 31 for reaction. During this process, the weight sensor 6 and the automatic valve 33 work together to accurately control the amount of material fed, thereby achieving accurate feeding of various raw materials. During the transportation process, the heat transfer oil circulates in the heat transfer oil coil 5 to heat and keep the raw materials warm.

[0055] Compared with existing technologies, the automatic feeding production system for wind power resin in this application eliminates queuing time in the feeding process, increases feeding efficiency by 400%, and achieves a maximum feeding speed of 25-30 tons / hour for a single mixing tank 21, with a daily production capacity of 250-300 tons of wind power resin. Furthermore, the large-angle elbow 34 reduces pipeline fluid resistance by 78%, increasing the flow velocity from 0.5m / s to 2.1m / s under the same pump power. The equipment utilization rate is over 95%, saving 22% energy compared to the traditional mode. It supports rapid switching between six formulations, reducing changeover time to 15 minutes.

[0056] Example 2: Refer to Figure 2 The difference between this embodiment and the above embodiments is that it also includes a slow storage tank 7, a coaxial injection pipe 8, and a phase separator 9.

[0057] The slow storage tank 7 is used to store low-viscosity sheath fluids that are immiscible with resin, such as polydimethylsiloxane. The slow storage tank 7 can be made of stainless steel, which has a certain degree of sealing and corrosion resistance, and can safely store sheath fluids.

[0058] Reference Figure 2 and Figure 3 The coaxial injection pipe 8 includes an inner pipe 81, an outer pipe 82, and a nozzle 83. The outer pipe 82 is coaxially sleeved on the inner pipe 81, and an annular conveying cavity 84 is formed between the outer pipe 82 and the inner pipe 81. The inner pipe 81 is connected to the resin tank group 12 and the resin storage tank 111 through the conveying pipe 31. The outer pipe 82 is connected to the slow storage tank 7 through the conveying pipe 31. The nozzle 83 is connected to both the inner pipe 81 and the outer pipe 82. The nozzle 83 is connected to the phase separator 9 through the conveying pipe 31.

[0059] The inner tube 81 and outer tube 82 can be made of materials such as stainless steel or plastic, depending on the characteristics of the conveying medium. For example, if the inner tube 81 conveys resin and the outer tube 82 conveys sheath fluid, both can be made of corrosion-resistant stainless steel. The nozzle 83 can mix the resin and sheath fluid conveyed from the inner tube 81 and outer tube 82 and then convey them to the conveying pipeline 31.

[0060] Multiple tangential holes 821 are provided on the outer tube 82, distributed around the axis of the outer tube 82. The tangential holes 821 are opened along the circumferential tangent direction of the outer tube 82. One end of the tangential hole 821 is connected to the annular delivery chamber 84, and the other end of the tangential hole 821 is connected to the slow storage tank 7 through the delivery pipe 31. The arrangement of the tangential holes 821 allows the sheath fluid to enter the annular delivery chamber 84 in a tangential direction, forming a rotating liquid flow, which better encapsulates the resin in the inner tube 81.

[0061] The inner diameter of the outer tube 82 gradually decreases along the direction of sheath fluid transport. According to the principles of fluid mechanics, when the fluid flow rate is constant, the smaller cross-sectional area of ​​the pipe will increase the fluid velocity, which will make the sheath fluid flow faster when it flows through the outer tube 82 and reach the nozzle 83 more quickly. This will form a more stable and faster-flowing sheath fluid layer in the pipe, which will allow the sheath fluid to better encapsulate the resin, enhance the lubrication effect on the resin, reduce the frictional resistance between the resin and the inner wall of the pipe, improve the resin transport efficiency in the pipe, and further improve the feeding efficiency of the entire wind power resin automatic feeding production system.

[0062] Reference Figure 1 and Figure 4 The number of phase separators 9 is equal to the number of stirred tanks 21. One phase separator 9 is located directly above one stirred tank 21 and is connected to one inlet 211 of the stirred tank 21. The additive tank assembly 14 is connected to another inlet 211 via a conveying pipe 31. The diluent tank assembly 13 is connected to the lower end of the phase separator 9, so that the resin detached from the phase separator 9 can be directly mixed with the diluent and enter the stirred tank 21. In other embodiments, the diluent tank assembly 13 may also be directly connected to another inlet 211.

[0063] Reference Figure 2 and Figure 3 Nozzle 83 is connected to three phase separators 9 via conveying pipe 31. Nozzle 83 can convey material into any one of the phase separators 9 via conveying pipe 31. The phase separators 9 are also connected to the slow storage tank 7 via pipes. In this embodiment, the phase separators 9 use gravity separation to separate the resin and sheath fluid. In other embodiments, the phase separators 9 may also be centrifugal separators, etc.

[0064] When the mixture of sheath fluid and resin is transported to the phase separator 9, the phase separator 9 separates the sheath fluid and resin. The separated sheath fluid can be transported back to the slow storage tank 7 through the pipeline for recycling, and the separated resin can be transported to the stirred tank 21 through the feed port 211.

[0065] The implementation principle of Example 2 is as follows: When wind power resin needs to be produced, the sheath liquid is first transported to the annular conveying chamber 84 using the power pump 32, so that the sheath liquid enters the conveying pipe 31 through the nozzle 83. The sheath liquid fills the nozzle 83 and the conveying pipe 31 and forms a stable flow. Then, the corresponding power pump 32 and automatic valve 33 are started according to the preset formula to transport the resin raw materials stored in the resin storage tank 111 and the resin tank group 12 to the inner pipe 81, so that the resin raw materials and sheath liquid merge at the nozzle 83, forming a core flow structure with resin as the "core" and sheath liquid as the "sheath". At this time, the low viscosity sheath liquid acts as a lubricating layer, separating the high viscosity resin from the inner wall of the pipe, so that the overall flow resistance is greatly reduced.

[0066] Next, the mixture of resin raw material and sheath fluid is conveyed through conveying pipe 31 to the corresponding phase separator 9. The phase separator 9 separates the sheath fluid and resin. The separated sheath fluid can be conveyed back to the slow storage tank 7 through the pipe, and the separated resin can be conveyed to the stirred tank 21 through the feed port 211. At the same time, diluent and additives are conveyed to the stirred tank 21 through another feed port 211 to realize the production of wind power resin. In this embodiment, only one stirred tank 21 is fed at a time.

[0067] When a formula needs to be changed, the delivery of raw materials is stopped, while the delivery of sheath fluid is continued. The sheath fluid is allowed to circulate in the delivery pipe 31 for a certain period of time to clean the delivery pipe 31, reduce the residue of raw materials in the delivery pipe 31, and prepare for the raw materials of the next different formula.

[0068] In addition, when it is necessary to produce wind power resins with multiple formulations at the same time, the sheath liquid is first transported back to the slow storage tank 7 for storage, and then the steps in Example 1 are repeated so that the resin raw material enters the stirred tank 21 through the phase separator 9, and the diluent and additives are transported to the stirred tank 21 respectively, so that multiple stirred tanks 21 can work at the same time to produce different wind power resins.

[0069] In another preferred embodiment, a coaxial injection pipe 8 may be provided for the resin storage tank 111 and the resin tank group 12 respectively, so as to transport the two resin raw materials separately.

[0070] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
