[0022] 1. Wastewater collection and pretreatment: Through the collection funnel connected to the bottom of the printing and dyeing box, the system can efficiently collect wastewater generated in the printing and dyeing process, avoiding direct discharge of wastewater into the environment, which is the first step to reduce environmental pollution. The ultrafiltration box and ultrafiltration components in the wastewater pretreatment mechanism can perform preliminary physical filtration treatment on the wastewater, remove large particle impurities and suspended matter, and reduce the burden for subsequent treatment. This step effectively improves the treatability of wastewater and lays the foundation for subsequent reuse or deep treatment.

[0023] 2. Wastewater post-treatment and waste separation: The design of the wastewater post-treatment mechanism is particularly critical, especially the combination of the flexible cleaning plate and the flexible cleaning block driven by the telescopic electric cylinder. This innovative design can intelligently clean the residual waste on the ultrafiltration component. As the telescopic electric cylinder extends, the flexible cleaning block deforms and concentrates the waste to the middle, and then discharges it through the waste pipe. This process not only improves the cleaning efficiency of the ultrafiltration component and extends its service life, but also ensures the effective separation and discharge of waste, reducing the decrease in filtration efficiency and the risk of secondary pollution caused by waste accumulation. The setting of the first solenoid valve further enhances the control flexibility of the system, and the timing and flow of waste discharge can be adjusted according to actual needs to optimize the waste treatment process.

[0024] 3. Filtered water reuse: The filtered water reuse mechanism is one of the highlights of the system. Through the combination of temporary storage tank, return pipe and water pump, the pre-treated wastewater can be reused. The filter adsorption component on the return pipe further improves the quality of the recycled water to ensure that it meets the supplementary water supply needs of the printing and dyeing system. This design significantly reduces the consumption of fresh water, reduces production costs, and alleviates environmental pressure.

[0025] 4. Overall environmental benefits: Overall, the textile environmental printing and dyeing system realizes the source control, process management and terminal reuse of wastewater discharge through the integrated wastewater treatment and reuse process, forming a closed-loop environmental protection system. This systematic treatment solution not only effectively reduces the amount of wastewater discharged and the content of pollutants in the wastewater, but also reduces the dependence on natural water resources through the resource utilization of wastewater, and has significant environmental and economic benefits.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, and are not intended to be exhaustive.

[0034] All embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0035] The first embodiment is an environmentally friendly printing and dyeing system for textiles, such as Figures 1 to 2 As shown, it includes a printing and dyeing mechanism, a wastewater collection mechanism, a wastewater pretreatment mechanism, a wastewater post-treatment mechanism, and a filtered water recycling mechanism; the printing and dyeing mechanism includes a printing and dyeing box 101, and the printing and dyeing box 101 has inlets and outlets for textiles to pass through on both sides, and the printing and dyeing box 101 is provided with a printing and dyeing component; the wastewater collection mechanism includes a collecting funnel 201 connected to the bottom of the printing and dyeing box 101; the wastewater pretreatment mechanism includes an ultrafiltration box 301 connected to the bottom of the collecting funnel 201, and the ultrafiltration component is arranged in the ultrafiltration box 301, and the bottom of the ultrafiltration box 301 is connected to the filtered water recycling mechanism through a negative pressure generator 303; the filtered water recycling mechanism includes a temporary storage box 401, and one side of the temporary storage box 401 is connected to a return pipe 402, and the return pipe 402 is used to supplement water supply for the printing and dyeing system, and a water pump 403 is arranged on the return pipe 402, and a filtering adsorption component is arranged in the return pipe 402; the wastewater post-treatment mechanism includes A horizontally placed telescopic electric cylinder 501 is arranged above the ultrafiltration component on one side of the ultrafiltration box 301, the movable part of the telescopic electric cylinder 501 movably penetrates the ultrafiltration box 301 and is fixedly connected with a cleaning plate 502, a flexible cleaning block 503 is bonded to the side of the cleaning plate 502 away from the telescopic electric cylinder 501, the flexible cleaning block 503 is set to be C-shaped, the bottom of the flexible cleaning block 503 is in contact with the upper surface of the ultrafiltration component, and a waste pipe 504 is connected to the side of the ultrafiltration box 301 away from the telescopic electric cylinder 501, the inlet of the waste pipe 504 corresponds to the middle of the flexible cleaning block 503, the other end of the waste pipe 504 is connected to the waste processing component, and a first solenoid valve 505 is arranged on the waste pipe 504; when the telescopic electric cylinder 501 is extended, the two sides of the flexible cleaning block 503 first contact the two sides of the inner wall of the ultrafiltration box 301 and deform, and the flexible cleaning block 503 concentrates the waste to the middle of the flexible cleaning block 503 as it deforms.

[0036] like Figures 1 to 2As shown, when the system is working, first, the textile enters the printing and dyeing box 101 through the inlet and outlet, and is printed and dyed under the action of the printing and dyeing components; the wastewater generated during the printing and dyeing process flows into the subsequent wastewater treatment system through the bottom of the printing and dyeing box 101; the wastewater generated during the printing and dyeing process is collected through the collecting funnel 201 at the bottom of the printing and dyeing box 101, thereby avoiding the direct discharge of the wastewater into the environment; the collected wastewater enters the ultrafiltration box 301, and undergoes preliminary physical filtration treatment through the ultrafiltration component; the ultrafiltration component can remove large particle impurities and suspended matter in the wastewater, purify the wastewater, and prepare for subsequent treatment; during the ultrafiltration process, the negative pressure generator 303 may be used to provide the necessary pressure difference to help the wastewater pass through the ultrafiltration membrane 323, and also help to guide the filtered water (i.e., "filtered water") to the filtered water reuse mechanism; above the ultrafiltration component, the telescopic electric cylinder 501 drives The flexible cleaning plate 502 and the flexible cleaning block 503 thereon perform waste cleaning work; when the telescopic electric cylinder 501 is extended, the flexible cleaning block 503 first contacts the two sides of the inner wall of the ultrafiltration box 301 and deforms, and with the deformation, the waste attached to the ultrafiltration component is concentrated to the middle of the flexible cleaning block 503; after the waste is concentrated in the middle of the flexible cleaning block 503, it is discharged through the waste discharge pipe 504, and the first solenoid valve 505 arranged on the waste discharge pipe 504 controls the discharge timing and flow rate of the waste; the waste finally enters the waste treatment component for further treatment or disposal; the filtered water after ultrafiltration treatment is collected in the temporary storage box 401; when the printing and dyeing system needs to supplement the water supply, the water pump 403 is started to transport the filtered water in the temporary storage box 401 back to the printing and dyeing system through the return pipe 402; the filter adsorption component on the return pipe 402 further purifies the filtered water to ensure that its quality meets the printing and dyeing requirements.

[0037] like Figure 1 As shown, the printing and dyeing assembly includes multiple groups of printing and dyeing roller groups 102, and the multiple groups of printing and dyeing roller groups 102 are arranged along the running direction of the textile. The printing and dyeing assembly is composed of multiple printing and dyeing roller groups 102, and each group of printing and dyeing roller groups 102 may include one or more printing and dyeing rollers, which may be active rollers or passive rollers, and are driven to rotate by motors or other driving devices. The printing and dyeing roller groups 102 are arranged in sequence according to the running direction of the textile in the printing and dyeing box 101, ensuring that the textile can pass through each group of printing and dyeing roller groups 102 in turn and receive continuous printing and dyeing treatment. The setting of multiple groups of printing and dyeing roller groups 102 ensures that the textile can be subjected to uniform and continuous printing and dyeing treatment. Each group of printing and dyeing roller groups 102 can perform a certain degree of printing and dyeing on the textile, and the combination of multiple groups of roller groups can achieve more complex printing and dyeing effects. Through the continuously arranged printing and dyeing roller groups 102, the textile can complete the printing and dyeing process in a shorter time, thereby improving the printing and dyeing efficiency. Different printing and dyeing roller groups 102 can be combined and adjusted as needed to meet the requirements of different textiles and printing and dyeing processes. This flexibility enables the printing components to be applied in a variety of printing scenarios.

[0038] like Figure 3 As shown, the ultrafiltration component is a support plate 321, and the support plate 321 is provided with a plurality of through holes 322, and an ultrafiltration membrane 323 is arranged in the through hole 322, which is a key part to realize the filtering function. The ultrafiltration membrane 323 is a membrane material with a microporous structure, and its pore size is between microfiltration and nanofiltration, which can intercept macromolecular substances, colloids, suspended matter, etc. in the fluid, while allowing water molecules, small molecular solutes, etc. to pass through. Through the filtering effect of the ultrafiltration membrane 323, the separation and purification of different components in the fluid are realized. The concentrated water side is enriched with the trapped impurities, while the clean water side obtains relatively pure water. This separation and purification process is realized based on the pore size screening effect of the ultrafiltration membrane 323.

[0039] like Figure 3 As shown, the support plate 321 includes two clamping plates 3211, through holes 322 are all opened at corresponding positions of the clamping plates 3211, the two clamping plates 3211 clamp the ultrafiltration membrane 323, the edges of the two clamping plates 3211 are fixedly connected, and a fixing ring 304 is fixedly arranged in the ultrafiltration box 301, and the fixing ring 304 is used to hold up the support plate 321. The support plate 321 is composed of two clamping plates 3211, and the two clamping plates 3211 are provided with through holes 322 at corresponding positions for installing the ultrafiltration membrane 323. The design of the clamping plates 3211 not only provides sufficient mechanical strength to support the ultrafiltration membrane 323, but also facilitates the replacement and maintenance of the ultrafiltration membrane 323. The two clamping plates 3211 fix the ultrafiltration membrane 323 in the through hole 322 by clamping. This clamping method ensures the stability of the ultrafiltration membrane 323 during the filtration process and prevents it from being displaced or damaged due to fluid pressure or vibration. The edges of the two clamping plates 3211 are firmly combined together by fixed connection (such as bolt connection, welding, etc.) to form a stable support structure. This fixed connection not only enhances the overall strength of the support plate 321, but also ensures the long-term stability of the ultrafiltration membrane 323 during the filtration process. The fixed ring 304 fixedly arranged in the ultrafiltration box 301 is mainly used to support the support plate 321 and the ultrafiltration membrane 323 thereon. The design of the fixed ring 304 enables the support plate 321 to maintain a horizontal state, avoiding sagging or deformation caused by gravity. At the same time, the fixed ring 304 also plays a certain shock-absorbing role, reducing the impact of fluid flow on the support plate 321 and the ultrafiltration membrane 323. The fixed ring 304 not only supports the support plate 321, but also fixes the relative position of the support plate 321 in the ultrafiltration box 301 through its position. This positioning effect ensures the stability and reliability of the ultrafiltration assembly during the filtration process, and prevents the filtration efficiency from decreasing or the equipment from being damaged due to position offset.

[0040] like Figure 4As shown, the filter adsorption component includes a multi-layer activated carbon layer 441, and a mesh cover plate 442 is closely arranged on both sides of the multi-layer activated carbon layer 441. A plurality of connecting arc plates 443 are arranged between the two mesh cover plates 442, and the connecting arc plates 443 wrap the edge of the activated carbon layer 441. The filter adsorption component adopts the design of a multi-layer activated carbon layer 441, which can increase the contact area and time between the fluid and the activated carbon, thereby improving the filtering and adsorption effects. Activated carbon has a strong adsorption capacity due to its porous structure, and can effectively adsorb impurities such as organic matter, residual chlorine, odor, and pigment in the fluid. When the fluid passes through the filter adsorption component, it first contacts the outermost activated carbon layer 441. In the process of flowing through the multi-layer activated carbon layer 441, the impurities in the fluid are gradually adsorbed in the pores of the activated carbon, thereby achieving purification and refining of the fluid. The filtering and adsorption effects of the activated carbon layer 441 are carried out simultaneously, which not only removes large particle impurities such as suspended matter in the fluid, but also adsorbs small molecular organic matter dissolved in the fluid. Two mesh cover plates 442 are respectively arranged closely on both sides of the multi-layer activated carbon layer 441. This design not only prevents the loosening and falling off of the activated carbon layer 441, but also avoids the direct impact and damage of the activated carbon layer 441 by the fluid during the circulation process. The material of the mesh cover plate 442 should have a certain strength and corrosion resistance to ensure that it can effectively support and protect the activated carbon layer 441 for a long time. A plurality of connecting arc plates 443 are arranged between the two mesh cover plates 442 and wrap the edge of the activated carbon layer 441. This design further enhances the stability of the activated carbon layer 441 and prevents its displacement and deformation during the flow of fluid. At the same time, the connecting arc plate 443 also plays a certain sealing role, reducing the possibility of fluid leakage from the edge of the activated carbon layer 441. The combination of the connecting arc plate 443 and the mesh cover plate 442 forms a stable overall structure, ensuring the reliability and durability of the filter adsorption assembly under various working conditions. This structural design also facilitates the disassembly and replacement of the filter adsorption assembly, improving the maintainability of the equipment.

[0041] like Figure 5 As shown, the flexible cleaning block 503 includes a C-shaped sponge block 531, and the sponge block 531 is wrapped with a waterproof cover 532. The sponge block 531 adopts a C-shaped design, and this shape gives the cleaning block a certain flexibility and adaptability. The C-shaped structure enables the sponge block 531 to better fit the curvature change of the surface to be cleaned, whether it is a plane, a curved surface or an edge, close contact and effective cleaning can be achieved. The waterproof cover 532 is tightly wrapped around the outside of the sponge block 531 to form a waterproof barrier. This barrier can effectively prevent liquids such as moisture and oil from penetrating into the inside of the sponge block 531, thereby keeping the sponge block 531 dry and clean. This is particularly important for the cleaning block that needs to be used in a water environment or when handling wet stains.

[0042] like Figures 1 to 2As shown, the waste treatment component includes a treatment box 601, which is the core part of the waste treatment component and is used to accommodate the waste to be treated. These wastes may contain harmful substances, pollutants or other components that need to be treated. The inside of the treatment box 601 provides a relatively closed environment, which is conducive to controlling the temperature, pressure and other conditions during the treatment process to ensure the treatment effect. A dosing box 602 is provided on the top of the treatment box 601, and the dosing box 602 is located at the top of the treatment box 601 for storing adsorbents or cleaning agents. These chemicals can react with harmful substances in the target waste, thereby achieving the purpose of purification or removal. The bottom of the dosing box 602 is connected to the top of the treatment box 601 through a second solenoid valve 603, and the bottom of the dosing box 602 is connected to the top of the treatment box 601 through a second solenoid valve 603. The solenoid valve is a valve that controls the on and off of the fluid by electromagnetic force, and has the advantages of rapid switching and precise control. In this embodiment, the second solenoid valve 603 is used to control the delivery of the adsorbent from the dosing box 602 to the treatment box 601.

[0043] When the waste in the treatment box 601 contains adsorbable pollutants, the adsorbent can combine with it and fix it on its own surface or pores, thereby removing the pollutants. By controlling the switch state of the second solenoid valve 603, the timing and amount of the adsorbent can be accurately controlled. This helps to flexibly adjust according to the actual situation of the waste and the treatment requirements to achieve the best treatment effect.

[0044] In the second embodiment, in this embodiment, the second solenoid valve 603 is used to control the delivery of the cleaning agent from the dosing box 602 to the treatment box 601. The cleaning agent may react with the target pollutant through chemical reaction, dissolution, complexation, etc., changing its chemical properties or physical state, making it easy to separate or harmless. By controlling the switch state of the second solenoid valve 603, the delivery time and delivery amount of the cleaning agent can be accurately controlled. This helps to flexibly adjust according to the actual situation of the waste and the treatment requirements to achieve the best treatment effect.

[0045] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0046] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be connected, detachably connected, or integrated; it can be mechanically connected or electrically connected; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.
