DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] In the description of the present invention, it should be noted that the terms "vertical," "upper," "lower," and "horizontal," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0021] like Figures 1-10 As shown, a pre-printing and dyeing bath treatment process based on biological enzymes includes the following steps: Step 1: Use a cold water device to soak the fabric in super-cold water, and use a fast impurity removal hot water device to soak the fabric in hot water. The fast impurity removal hot water device is connected to an ultrasonic generator 6 and a wetting agent replenishing mechanism. The ultrasonic generator 6 is used to vibrate the hot water to promote the moisture penetration efficiency of the fabric. The wetting agent replenishing mechanism is used to replenish the hot water with wetting agent. The wetting agent makes it easier for the hot water to spread and penetrate into the fiber, thereby avoiding fabric floating and uneven treatment. The cold water device and the rapid impurity removal hot water device are both connected to the waste heat recovery system and the sewage treatment system; By combining a cold water device with a rapid impurity removal hot water device, a two-stage treatment process of "pre-wetting and rapid impurity removal" is achieved. The cold water device can initially wet the fabric fibers, reducing the risk of thermal expansion and contraction, and improving the hot water treatment effect. The rapid impurity removal hot water device is equipped with an ultrasonic generator 6 and a wetting agent replenishment mechanism. The wetting agent can significantly reduce the surface tension of the hot water, allowing the hot water to more easily penetrate deep into the fabric fibers, avoiding uneven treatment caused by floating. The ultrasonic generator 6 provides high-frequency vibrations through a piezoelectric ceramic transducer, enhancing the stripping force of impurities from the fiber surface, improving treatment efficiency and reducing hot water immersion time, thereby achieving the purpose of rapid and efficient impurity removal.

[0022] In addition, the rapid impurity removal hot water device in this step is connected to the waste heat recovery system, which can effectively recover the heat energy in the treatment process and reduce overall energy consumption; at the same time, it is linked with the sewage treatment system to process the treatment liquid in time, reduce the burden of wastewater discharge, and improve the overall environmental performance of the process.

[0023] Step 2: The fabric is padded using a padding device, wherein the padding device is filled with an enzyme treatment solution including protease and nanocellulose, wherein the mass of the protease accounts for 0.05-0.2% of the mass of the enzyme treatment solution, and the mass of the nanocellulose accounts for 0.01-0.1% of the mass of the enzyme treatment solution, and the padding device is connected to a sewage treatment system; The enzyme treatment solution used in this step consists of protease and nanocellulose. Protease, as a biological enzyme, possesses excellent protein degradation capabilities, effectively removing residual protein impurities from natural fibers. Nanocellulose, with its excellent dispersibility and interfacial activity, enhances the contact reaction between the enzyme and the fiber surface, promoting uniform distribution of the treatment solution throughout the fabric. The low concentrations of protease and nanocellulose ensure effective treatment while reducing additive costs, in line with the trend of green and sustainable development. The padding method further enhances the uniformity and efficiency of the treatment solution's penetration into the fabric, facilitating subsequent processing steps.

[0024] Step 3: steaming the fabric using a steaming system; Step 4: using an enzyme inactivation system to inactivate enzymes on the fabric; Step 5: Wash the fabric using a water washing system, which is connected to a sewage treatment system; The washing system removes residual enzymes, floating colors, and impurities, ensuring that the fabric meets the cleanliness standards required for subsequent printing and dyeing. Furthermore, the system is connected to the wastewater treatment system, enabling timely recycling and purification of wastewater, reducing environmental pollution and enhancing the green sustainability of the process.

[0025] Step 6: Use a dryer to dry the fabric.

[0026] The moisture content of the fabric after drying is low, making it easier to enter the next process such as shaping, sizing, and printing.

[0027] like Figures 1-10 As shown, a bio-enzyme-based pre-printing and dyeing bath treatment system includes the cold water device, the rapid impurity removal hot water device, the padding device, the steaming system, the enzyme inactivation system and the water washing system arranged in accordance with the process sequence in the bio-enzyme-based pre-printing and dyeing bath treatment process; The cold water device, the rapid impurity removal hot water device and the water washing system are all connected to the sewage treatment system. The rapid impurity removal hot water device is connected to the waste heat recovery system. The sewage treatment system includes a grid filtration system and a biochemical treatment system.

[0028] The control and management system is used to coordinate, regulate and monitor the operating status of each sub-device in the entire bio-enzyme-based pre-printing and dyeing bath treatment system.

[0029] According to an optional embodiment of the present invention, the rapid impurity removal hot water device includes a main seat 1 and a lifting box 4.

The ultrasonic generator 6 is fixed to the bottom wall of the box cavity 5. The wetting agent replenishing mechanism includes a pillar 7, a guide bar 8, a control rod 9, a transmission wheel assembly 10, a transmission wheel assembly 2 12 and a driving mechanism. The two pillars 7 are fixed to the top wall of the main seat 1. The guide bar 8 and the control rod 9 are fixed between the two pillars 7. The control rod 9 is provided with an undulating surface. The transmission wheel assembly 10 is rotatably connected to the guide bar 8. The transmission wheel assembly 2 12 is rotatably connected to the top wall of the main seat 1. The transmission wheel assembly 10 is connected to the transmission wheel assembly 2 12 through a transmission belt 11. The transmission belt 11 is fixed with a linkage bar 13. The driving mechanism is connected to the main seat 1. The driving mechanism is connected to the transmission wheel assembly 2 12. The guide bar 8 is slidably connected with a slide 24. The slide 24 is slidably connected with a liquid reservoir 15. The top wall of the liquid reservoir 15 is fixed with two vertical plates 14. The linkage bar 13 extends between the two vertical plates 14. A liquid storage chamber 16 and a measuring chamber 20 are provided on the liquid reservoir 15. The bottom wall of the liquid storage chamber 16 is connected to the top wall of the measuring chamber 20 through the transmission chamber 17. The measuring chamber 20 is connected to the bottom wall of the liquid reservoir 15. The liquid storage chamber 16 is filled with a wetting agent. The inner wall of the transmission chamber 17 is rotatably connected to a transmission impeller 18. The liquid reservoir 15 is rotatably connected to a gear 19. The gear 19 and the transmission impeller 18 are fixedly connected. The bottom wall of the liquid reservoir 15 is slidably connected to a curved door 21. The curved surface of the curved door 21 is offset against the undulating surface on the control rod 9. The curved door 21 is connected to the liquid reservoir 15 through a reset spring 30. The bottom wall of the liquid reservoir 15 is connected to a moving wheel 22. The moving wheel 22 is offset against the top wall of the lifting box 4. A rack 23 is fixed to one of the pillars 7.

[0030] According to an optional embodiment of the present invention, the driving mechanism includes a motor 27 and a gear 2 28. The motor 27 is fixed to the main seat 1, the gear 2 28 is fixed to the rotor of the motor 27, and the transmission wheel assembly 2 12 is fixed with a gear 3 29, and the gear 3 29 is engaged with the gear 2 28.

[0031] According to an optional embodiment of the present invention, the outer diameter of the gear three 29 is greater than the outer diameter of the gear two 28 .

[0032] This structure uses motor 27 to drive gear 2 (28), which in turn drives gear 3 (29), achieving a coordinated wetting agent replenishment mechanism. Gear 3 (29) has a larger outer diameter than gear 2 (28), creating a deceleration and force-amplification mechanism. This allows the drive system to output greater torque at lower speeds, improving operational stability and mechanical durability. This design effectively ensures smooth and precise wetting agent release.

[0033] According to an optional embodiment of the present invention, a slope is provided on the measuring chamber 20. The design of the slope facilitates the complete outflow of the wetting agent.

[0034] According to an optional embodiment of the present invention, transmission teeth are provided on the transmission wheel assembly 10, the transmission belt 11, and the transmission wheel assembly 2 12. The provided transmission teeth enhance the frictional grip of the transmission belt 11, preventing slippage and displacement caused by load changes or long-term operation, thereby ensuring multi-point delivery of the wetting agent, suitable for continuous industrial operation.

[0035] According to an optional embodiment of the present invention, a pump body 25 is fixedly connected to the inner wall of the tank cavity 5, and a liquid outlet pipe 26 is fixedly connected to the pump body 25. The arrangement of the pump body 25 and the liquid outlet pipe 26 enables the discharge of liquid from the tank cavity 5, facilitates rapid replacement of hot water, realizes heat energy utilization or discharges residual liquid, is suitable for a closed-loop circulation system, and is beneficial for heat energy recovery, energy conservation and consumption reduction.

[0036] According to an optional embodiment of the present invention, the ultrasonic generator 6 is provided with a power module and an ultrasonic transducer.

[0037] According to an optional embodiment of the present invention, the ultrasonic transducer includes a piezoelectric ceramic transducer.

[0038] The ultrasonic generator 6 houses a power module and ultrasonic transducer, ensuring stable high-frequency ultrasonic signal output, enhancing impurity removal and penetration. The power module provides continuous and stable power, while the piezoelectric ceramic transducer offers advantages such as low energy consumption, stable frequency, and strong amplitude. These advantages significantly improve hot water impurity removal efficiency, reduce reliance on additives, and enhance the environmental friendliness and economic efficiency of the treatment.

[0039] Implementation process of the rapid impurity removal hot water device: hot water is added to the box cavity 5, so that the lifting box 4 overcomes the elastic force of the supporting spring 3 and moves downward until the gear 19 just meshes with the rack 23, and the fabric is added to the hot water, the mass of the lifting box 4 increases, and the lifting box 4 overcomes the elastic force of the supporting spring 3 and moves downward. The greater the mass of the fabric, the greater the downward movement of the lifting box 4. Since the moving wheel 22 and the top wall of the lifting box 4 are against each other, the liquid reservoir 15 moves downward as the lifting box 4 moves downward under the action of its own gravity, and the liquid reservoir 15 moves downward along the slide 24. The rack 23 drives the rotation of the gear 19. There are gaps between the blades on the transfer impeller 18, and the wetting agent in the liquid storage chamber 16 will flow into the gaps. After the transfer impeller 18 rotates, it will bring the wetting agent from the transfer chamber 17 to the measuring chamber 20 for storage. The greater the downward movement of the lifting box 4, the greater the rotation angle of the gear 19, and the greater the rotation angle of the transfer impeller 18 driven by the gear 19, and the more wetting agent transported to the measuring chamber 20 by the transfer impeller 18.

[0040] Turn on the motor 27 and the ultrasonic generator 6. The motor 27 causes the rotor to drive the gear 2 28 to rotate. The gear 2 28 drives the gear 3 29, the transmission wheel assembly 2 12, the transmission belt 11, and the transmission wheel assembly 10 to rotate. The transmission belt 11 drives the linkage bar 13 to move along the movement trajectory of the transmission belt 11. The linkage bar 13 drives the two vertical plates 14 to reciprocate left and right, thereby causing the liquid reservoir 15 and the slide 24 to reciprocate left and right along the guide bar 8. The undulating surface on the control rod 9 pushes the curved door 21 to overcome the elastic force of the return spring 30 and move backward. The curved door 21 releases the blockage of the measuring chamber 20. As a result, part of the wetting agent in the measuring chamber 20 flows into the hot water in the box chamber 5. Under the combined action of the thrust of the undulating surface of the control rod 9 and the elastic force of the return spring 30, the curved door 21 moves back and forth, so that the liquid reservoir 15 releases the wetting agent to different positions of the hot water. The wetting agent can improve the hydrophilicity of the fabric, reduce the surface tension of water, make it easier for the hot water to spread and penetrate into the fiber, avoid fabric floating or uneven treatment, and improve the efficiency of hot water impurity removal. The wetting agent and ultrasonic wave work together to enhance the lubrication and peeling of the interface between water and impurities, which helps to achieve efficient impurity removal in a short time.

[0041] The piezoelectric ceramic transducer in the ultrasonic generator 6 makes the hot water vibrate, which can enhance the efficiency of hot water in stripping impurities from the fabric. The ultrasonic wave produces cavitation effect and microjets in the water, which can physically break up and disperse natural impurities on the fiber surface, such as wax, protein, mud, residual slurry, etc., so that the impurities are desorbed from the fabric surface and suspended in the water, and can also promote water penetration into the fabric structure. The fine capillary structure between the fabric fibers can be opened through ultrasonic vibration, thereby improving the penetration efficiency of hot water and subsequent enzyme solution into the fibers, improving the overall pretreatment uniformity, and reducing the use of chemical additives. The physical impurity removal effect of ultrasonic waves can reduce the concentration of additives required for impurity removal, which helps to improve the level of green environmental protection.

[0042] Beneficial effects of this implementation process: The device realizes load response function through the cooperation of lifting box 4 and supporting spring 3. When the fabric is added, the lifting box 4 moves downward to drive the displacement of liquid reservoir 15, automatically controlling the amount of wetting agent added, making the amount of wetting agent used more accurate under different fabric weight conditions, thereby avoiding waste and ensuring uniform treatment; The conveying impeller 18 in the wetting agent replenishing mechanism is linked to the gear 19. Combined with the transmission structure and the undulating surface design on the control rod 9, it can achieve quantitative, multi-point, and cyclic release of the wetting agent, significantly improving the uniformity of contact between hot water and fabric and the wettability. The linkage bar 13 drives the liquid reservoir 15 to move back and forth left and right through the transmission belt 11. Combined with the coordinated design of the curved door 21 and the control rod 9, the wetting agent can be distributed at multiple positions in the box cavity 5, so that the wetting agent in the hot water is distributed more evenly, further avoiding uneven treatment. The ultrasonic generator 6 significantly improves the efficiency of removing impurities from the fabric surface through the cavitation effect and micro-jet action generated by the piezoelectric ceramic transducer. It is particularly suitable for removing natural impurities such as wax, protein, residual sizing, etc., achieving efficient physical impurity removal. The synergistic effect of hot water treatment, wetting agents, and ultrasound can quickly open the capillary structure between fibers, improve water permeability, shorten soaking time, and enhance the penetration and reaction effect of subsequent enzyme treatment processes, thereby effectively improving the efficiency of the entire pre-treatment process; The device of the present invention has a compact structure and a high degree of automation. Many components such as the main seat 1, the guide rail 8, the transmission wheel assembly 1 10, the transmission wheel assembly 2 12, the motor 27, the gear 2 28, the gear 3 29, etc. are all standard mechanical components, which are convenient for assembly and maintenance and have good industrial feasibility.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
