[0030] Reference Figures 1 to 2 According to an embodiment of the present invention, the long flax fiber degumming system includes a conveying device 10, a spraying device 20, and a liquid storage device 30. The conveying device 10 is configured to convey long flax fibers 1; the spraying device 20 is disposed on both sides of the conveying device 10, and includes spraying mechanisms 21 arranged sequentially at intervals along the conveying direction of the conveying device 10, with adjacent spraying mechanisms 21 interconnected. The long flax fibers 1 are located between the spraying mechanisms 21, and the long flax fibers 1 can be continuously conveyed between the arranged spraying mechanisms 21. The spraying mechanism 21 includes spray heads 2122, the spraying direction of which is towards the long flax fibers 1, and the spray heads 2122 are configured to spray degumming liquid or spray gas; the liquid storage device 30 is disposed below the spraying device 20 and connected to the spraying device 20, and is used to store the sprayed degumming liquid.

[0031] This utility model discloses a long flax fiber degumming system. Through the cooperation of a conveying device 10, a spraying device 20, and a liquid storage device 30, it achieves efficient and continuous degumming of long flax fibers 1. The system utilizes spraying mechanisms 21 within the spraying device 20, arranged sequentially and at intervals along the conveying direction of the conveying device 10. This allows the long flax fibers 1 to be continuously conveyed between the arranged spraying mechanisms 21, receiving uniform and thorough spraying treatment. The spray heads 2122 can be flexibly configured to spray degumming liquid or spray gas, satisfying the chemical treatment requirements during the degumming process and achieving cleaning or drying / dispersing effects through gas spraying, thus improving the flexibility and efficiency of the degumming process. Simultaneously, the liquid storage device 30 effectively collects the sprayed degumming liquid, achieving resource recycling and reducing production costs and environmental pollution.

[0032] Specifically, the long flax fiber degumming system of this embodiment mainly includes three parts: a conveying device 10, a spraying device 20, and a liquid storage device 30. The conveying device 10 adopts a belt conveyor or a chain conveyor, which is configured to convey long flax fibers 1. The conveyor has the advantages of simple structure, stable operation, and long conveying distance, and is suitable for continuous conveying of long flax fibers 1. The spraying device 20 is set on both sides of the conveying device 10 and includes multiple spraying mechanisms 21 arranged sequentially and at intervals along the conveying direction. Adjacent spraying mechanisms 21 are interconnected to ensure uniform distribution and flow of spray liquid. The long flax fibers 1 are located between the spraying mechanisms 21 and can continuously pass through the arranged spraying mechanisms 21 as the conveying device 10 operates, receiving layer-by-layer degumming spray treatment. Each spraying mechanism 21 includes multiple spray heads 2122, and the spraying direction of the spray heads 2122 is towards the long flax fibers 1 to ensure that the spray liquid or gas can directly act on the surface of the long flax fibers 1. The spray head 2122 can be configured to spray degumming liquid (such as a chemical degumming agent) or spray gas (such as air or dry high-temperature gas) according to actual needs to meet the requirements of the drying stage. A liquid storage device 30 is located below the spray device 20 and connected to it. The liquid storage device 30 is used to store the sprayed degumming liquid for subsequent recycling. The liquid storage device 30 can be in the form of a storage tank or pool, and its capacity can be set according to actual production needs.

[0033] In actual use, the long flax fiber 1 is continuously conveyed to the spraying device 20 via the conveying device 10. The spray heads 2122 in the spraying device 20 sequentially spray the long flax fiber 1 according to a preset spraying program. When degumming liquid is required, the spray heads 2122 evenly spray the degumming liquid onto the surface of the long flax fiber 1, allowing it to fully saturate and undergo a chemical reaction to achieve degumming. When gas is required, the spray heads 2122 spray air or steam to clean or dry the long flax fiber 1. The degumming liquid flows into the storage device 30 during the spraying process. After filtration and sedimentation, it can be reused for spraying, achieving resource recycling. In summary, the long flax fiber degumming system of this embodiment, through the cooperation of the conveying device 10, the spraying device 20, and the storage device 30, achieves efficient and continuous degumming of the long flax fiber 1. The system has the advantages of simple structure, convenient operation, high degumming efficiency and low resource consumption, and is suitable for large-scale degumming production of long flax fiber.

[0034] Therefore, it is understood that the long flax fiber degumming system according to the present utility model embodiment has at least the following beneficial effects: by connecting two adjacent spraying mechanisms 21 to each other, the long flax fiber 1 can be continuously conveyed by the conveying device 10 and sequentially sprayed by multiple spraying mechanisms 21. The long flax fiber 1 is continuously and uninterruptedly degummed layer by layer by degumming liquid or gas and then air-dried and dispersed, thereby enabling continuous and uninterrupted production of the long flax fiber 1 and improving the production efficiency of the long flax fiber 1; in addition, degumming resources can be saved by spraying.

[0035] Reference Figure 1 In some embodiments of this utility model, the conveying device 10 includes a conveying chain 11 and a plurality of suspension hooks 12. The conveying chain 11 is disposed above the spraying device 20. The plurality of suspension hooks 12 are arranged at intervals along the length direction of the conveying chain 11 on the conveying chain 11. The suspension hooks 12 are configured to hang long hemp fibers 1. The conveying direction of the conveying chain 11 is parallel to the arrangement direction of the spraying mechanism 21.

[0036] In the long flax fiber degumming system of this invention, the conveying device 10 includes a conveyor chain 11 and multiple hanging hooks 12. This design ensures that the long flax fiber 1 can be stably and continuously passed through the spraying device 20 for degumming treatment. In a specific embodiment, the conveyor chain 11 is positioned above the spraying device 20, which allows the long flax fiber 1 to remain suspended during spraying, facilitating the uniform application of the sprayed liquid or gas to the fiber surface. Multiple hanging hooks 12 are arranged at intervals along the length of the conveyor chain 11, and these hooks 12 are configured to attach the long flax fiber 1. The design of the hanging hooks 12 can be adjusted according to the characteristics of the long flax fiber 1 and the processing requirements to ensure a secure attachment without damaging the fiber.

[0037] In actual operation, the long flax fiber 1 is hung on the hook 12 and moves with the operation of the conveyor chain 11. The conveying direction of the conveyor chain 11 is parallel to the arrangement direction of the spraying mechanism 21, which ensures that the long flax fiber 1 can continuously and evenly pass through each spraying mechanism 21 and receive spraying treatment. When the long flax fiber 1 moves to the bottom of the spraying mechanism 21, the spray head 2122 starts to work, spraying degumming liquid or gas onto the fiber surface to achieve degumming or other treatment effects.

[0038] Reference Figure 1In some embodiments of this utility model, the spraying mechanism 21 includes a mounting frame 211 and a plurality of spraying components 212. The mounting frame 211 is disposed on both sides of the conveying device 10, and the long hemp fiber 1 is located between the mounting frames 211. The plurality of spraying components 212 are disposed on the inner side of the mounting frame 211. The spraying component 212 includes a plurality of spray heads 2122 and a mounting base 2121. The mounting base 2121 is mounted on the mounting frame 211, and the plurality of spray heads 2122 are arranged along the conveying direction of the conveying device 10.

[0039] In the long flax fiber degumming system of this invention, the design of the spraying mechanism 21 is crucial for achieving efficient and uniform spraying treatment. In a specific embodiment, the spraying mechanism 21 includes a mounting frame 211 and several spraying components 212. The mounting frame 211 is disposed on both sides of the conveying device 10, providing a stable support structure for the spraying components 212. The long flax fibers 1 are located between the mounting frames 211 during the conveying process. This design ensures that the liquid or gas sprayed from the spray heads 2122 can directly and uniformly act on the fiber surface. The spraying components 212 are disposed on the inner side of the mounting frame 211. Each spraying component 212 includes multiple spray heads 2122 and a mounting base 2121. The mounting base 2121 is used to fix the spraying components 212 on the mounting frame 211, ensuring that the position and spraying direction of the spray heads 2122 are stable and reliable. Multiple spray heads 2122 are arranged along the conveying direction of the conveying device 10. This allows the long flax fibers 1 to receive spray treatment from different positions as they continuously pass through the spraying mechanism 21, achieving a comprehensive and uniform degumming effect. During actual operation, the spray heads 2122 spray degumming liquid or gas at a certain pressure and flow rate according to a preset spraying program and operating parameters, forming fine spray droplets or airflow that evenly covers the surface of the long flax fibers 1. By adjusting parameters such as the arrangement density, spray angle, and spray pressure of the spray heads 2122, the spraying effect can be optimized, improving degumming efficiency and quality.

[0040] Reference Figure 1 In some embodiments of this invention, the height of the spray assembly 212 on the mounting frame 211 is adjustable. In the long flax fiber degumming system of this invention, to further optimize the spraying effect and adapt to long flax fibers 1 of different specifications and thicknesses, the spray assembly 212 is designed with adjustable height. In a specific embodiment, the spray assembly 212 is fixed to the mounting frame 211 by a mounting structure that allows the spray assembly 212 to be adjusted vertically. For example, a combination of a threaded adjusting rod or a groove and a slider can be used, allowing the spray assembly 212 to be easily raised or lowered as needed.

[0041] During the adjustment process, the operator can adjust the height of the spray assembly 212 manually or with tools according to the actual thickness of the long flax fiber 1 and the degumming requirements. When processing thicker long flax fibers 1, the spray assembly 212 can be raised appropriately to ensure that the spray liquid or gas can fully cover the upper surface of the fiber; while when processing thinner long flax fibers 1, the spray assembly 212 can be lowered appropriately to avoid waste or uneven processing caused by over-spraying.

[0042] Reference Figures 1 to 2 In some embodiments of this utility model, the liquid storage device 30 includes a liquid collection tank 31, which is located below the long hemp fiber 1. The liquid collection tank 31 is connected to the spraying mechanism 21. The upper end of the liquid collection tank 31 has a collection port 3111, which is configured to collect the degumming liquid.

[0043] In the long flax fiber degumming system of this invention, the design of the liquid storage device 30 is crucial for achieving the recycling of the degumming liquid and reducing environmental pollution. Specifically, the liquid storage device 30 includes a collection tank 31, which is positioned below the long flax fiber 1. This positioning ensures that the degumming liquid dripping during spraying flows directly into the collection tank 31, avoiding splashing and waste. The collection tank 31 is connected to the spraying mechanism 21 via a pipe or other suitable connection method, ensuring that the degumming liquid used in the spraying mechanism 21 flows smoothly back into the collection tank 31 after spraying. A collection port 3111 is provided at the upper end of the collection tank 31, configured to collect the degumming liquid dripping from the spray head 2122. The size and shape of the collection port 3111 can be adjusted according to the actual spraying effect and liquid flow rate to ensure that the liquid is completely and without leakage. In actual operation, after the spraying mechanism 21 sprays the long hemp fiber 1, the degumming liquid flows along the fiber surface and eventually drips into the collection port 3111 of the collection tank 31. After filtration, sedimentation and other treatments, the liquid in the collection tank 31 can be pumped back to the spraying mechanism 21 for recycling, thus realizing the efficient recycling of the degumming liquid.

[0044] Furthermore, referring to Figure 2 In some embodiments of this utility model, the liquid collection tank 31 includes a collection pool 311, a filter pool 312, and a liquid collection pool 313. The collection pool 311 is disposed above the liquid collection pool 313, the filter pool 312 is disposed below the liquid collection pool 313, the collection pool 311 has a collection port 3111, the collection pool 311 is connected to the filter pool 312, the filter pool 312 is connected to the liquid collection pool 313, and the liquid collection pool 313 is connected to the spraying mechanism 21.

[0045] In the long flax fiber degumming system of this utility model, to further improve the function of the liquid storage device 30 and achieve effective collection, filtration, and recycling of the degumming liquid, the liquid collection tank 31 is designed to include three main parts: a collection pool 311, a filtration pool 312, and a collection tank 313. Specifically, the collection pool 311 is positioned above the collection tank 313, directly receiving the degumming liquid dripping from the spray head 2122. The collection pool 311 has the aforementioned collection port 3111, which ensures that the liquid flows smoothly into the collection pool 311. To prevent liquid splashing or evaporation, the collection pool 311 can be designed with a certain depth and width, and its inner wall can be made of corrosion-resistant material to adapt to the chemical properties of the degumming liquid. The filtration pool 312 is located below the collection tank 313 and is connected to the collection pool 311 via a pipe or other suitable connection method. The main function of the filter tank 312 is to remove impurities and solid particles from the degumming liquid to ensure its cleanliness. The filter tank 312 can be equipped with filter screens, filter cloths, or other filter media, which can be selected and replaced according to the characteristics of the liquid and filtration requirements. The collection tank 313, as the final part of the liquid storage device 30, is connected to the filter tank 312 and also to the spray mechanism 21. The clean liquid treated by the filter tank 312 is collected in the collection tank 313, awaiting pumping back to the spray mechanism 21 for recycling. The design of the collection tank 313 should consider the liquid storage capacity and pumping requirements to ensure continuous system operation.

[0046] In actual operation, the degumming liquid drips from the spray head 2122, first entering the collection tank 311, then being filtered by the filter tank 312, and finally flowing into the collection tank 313. When the spraying mechanism 21 needs to reuse the degumming liquid, the liquid is pumped out from the collection tank 313 and transported through pipelines to the spray head 2122 for spraying. In this way, the degumming liquid forms a closed loop within the system, achieving efficient utilization and reducing waste.

[0047] Reference Figure 2In some embodiments of this invention, a filter layer 314 is provided between the collection tank 313 and the filter tank 312. The filter layer 314 is configured to filter impurities in the degumming liquid. The filter layer 314 is placed in the connecting channel between the collection tank 313 and the filter tank 312, or is part of the filter tank 312, directly undertaking the task of filtering impurities in the degumming liquid. This filter layer 314 can be made of various materials, such as mesh, filter cloth, activated carbon, or other media with filtration functions. The specific selection depends on the composition of the degumming liquid, the type of impurities, and the filtration requirements. The design of the filter layer 314 fully considers the fluidity of the liquid and the filtration efficiency. It must ensure that the liquid can pass through smoothly while ensuring that impurities are effectively intercepted. Therefore, the pore size, thickness, and material selection of the filter layer 314 have been carefully calculated and experimentally verified to achieve the best filtration effect.

[0048] In some embodiments of this utility model, the filter tank 312 has a drain outlet (not shown in the figure), configured to discharge impurities from the degumming liquid. The drain outlet is designed at the bottom or side of the filter tank 312, with the location chosen to facilitate impurity discharge. The drain outlet can be an openable and closable valve or other types of openings, as long as they ensure smooth discharge of impurities when needed. During the filtration process, impurities in the degumming liquid are intercepted by the filter layer 314 and retained within the filter tank 312. Over time, impurities in the filter tank 312 gradually accumulate. To maintain the cleanliness and filtration effect of the filter tank 312, it is necessary to periodically or according to the accumulation of impurities, discharge them through the drain outlet. In actual operation, when impurities need to be discharged, simply open the drain outlet valve or other opening, and the impurities in the filter tank 312 will be discharged with the flow of the liquid or by gravity. The discharge process can be performed manually or through an automatic control system to achieve timed or quantitative discharge. The impurities contain detached organic matter, which can also be used as bio-fertilizer.

[0049] In some embodiments of this utility model, the degumming liquid includes a biological degumming solution, a rinsing solution, and a chemical degumming solution, and multiple spraying mechanisms 21 spray the biological degumming solution, the rinsing solution, and the chemical degumming solution separately.

[0050] In this novel long flax fiber degumming system, various degumming liquids are employed to achieve efficient and flexible degumming treatment, including biological degumming solutions, rinsing solutions, and chemical degumming solutions. Furthermore, the system is equipped with multiple spraying mechanisms 21, each individually responsible for spraying different degumming liquids.

[0051] In practice, the biological degumming solution is a solution containing microorganisms or enzymes that decomposes the gum components in flax fibers 1 through biological action, achieving a gentle and environmentally friendly degumming effect. A dedicated spraying unit 21 is configured to spray this biological degumming solution, ensuring that the solution evenly and fully covers the surface of the flax fibers 1, maximizing its biological degumming effect. The rinsing solution is used to clean the flax fibers 1 during the degumming process, removing residues and impurities from the fiber surface. Another spraying unit 21 is specifically designed to spray the rinsing solution, enabling thorough cleaning of the fibers after biological or chemical degumming, ensuring the stability and consistency of the degumming effect. The chemical degumming solution is a solution containing chemical reagents that rapidly and effectively decomposes the gum components in the flax fibers 1 through chemical action. A third spraying unit 21 is configured to spray this chemical degumming solution, which can be used when rapid degumming is required or when treating gums that are difficult to biodegrade. Multiple spray units 21 spray different degumming liquids individually, which not only achieves flexibility and controllability in the degumming process, but also avoids mutual interference and reactions between different liquids, ensuring the stability and reliability of the degumming effect. At the same time, this design also makes the system maintenance and upkeep simpler and more convenient, improving the system's efficiency and lifespan.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
