Description

Technical Field

[0001] This utility model relates to a processing machine, specifically a liquid spraying fabric surface treatment machine. Background Technology

[0002] Against the backdrop of global advocacy for sustainable development, the textile printing and dyeing industry faces unprecedented resource and environmental challenges. Transforming and upgrading traditional dyeing and finishing processes and pioneering clean production technology pathways have become crucial for promoting the sustainable development of the textile printing and dyeing industry.

[0003] Traditional textile dyeing and finishing processes heavily rely on water as a transfer medium, applying dyes and functional auxiliaries to fabrics through methods such as immersion, padding, printing, and transfer. However, this traditional model has many drawbacks. From a performance perspective, these application methods result in unstable dyeing and finishing effects, leading to inconsistent product quality and failing to meet market demands for high-quality fabrics. The lengthy process cycle not only reduces production efficiency but also increases time costs and cash flow pressure for businesses. Regarding energy consumption, traditional processes have huge demands for water, electricity, and gas, and the persistently high energy consumption significantly increases operating costs, a problem that becomes increasingly prominent with rising energy prices.

[0004] Of particular concern is that traditional dyeing and finishing processes generate large amounts of wastewater containing complex and toxic components. If this wastewater is discharged directly without effective treatment, it will severely pollute the soil, water bodies, and other ecological environments, threatening the balance of the ecosystem and human health. Furthermore, traditional dyeing and finishing processes are significantly inadequate in terms of reliance on manual labor and process control. Extensive manual operation not only increases labor costs but also makes precise control of the production process difficult due to human factors, leading to energy waste and ineffective resource depletion.

[0005] With increasingly stringent environmental, energy consumption, and carbon emission restrictions, the drawbacks of traditional dyeing processes have become more pronounced. They fail to effectively address color difference issues, suffer from poor production stability, struggle to improve production efficiency, exhibit low effective resource utilization, and maintain consistently high energy consumption. Furthermore, traditional processes have low levels of digitalization, making enterprise management difficult, and emission standards have become a bottleneck restricting industry development and proving difficult to overcome. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the prior art, this utility model provides a spray-type fabric surface treatment machine, which effectively solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: This utility model includes:

[0008] The suction hood has a fabric inlet and a fabric outlet on its two sides, respectively.

[0009] The VOC duct is connected to one side of the top of the suction hood;

[0010] A collection hood is connected to the bottom of the suction hood, and a liquid collection hopper is provided at the bottom of the collection hood;

[0011] Several spray pipes are horizontally arranged inside the suction hood and perpendicular to the direction of fabric travel;

[0012] The nozzles are arranged in an array at the bottom of each spray pipe. The nozzles have a spray angle of 0°-110° and the spray surfaces of adjacent nozzles form a continuous atomized area.

[0013] Preferably, 3-5 groups of spray pipes are arranged along the fabric travel direction, and the spacing between each group of spray pipes is 150-300mm.

[0014] Preferably, the spray angle of the nozzle is 90°-110°, and the spray axis of each nozzle forms an inclination angle of 15°-45° with the horizontal plane.

[0015] Preferably, the bottom of the liquid collecting hopper has a V-shaped structure with an inclination angle of 30°-60°, and is equipped with a guide channel and a drain port.

[0016] Preferably, the center-to-center distance between adjacent nozzles is 80-120mm, and the atomization coverage diameter of each nozzle is 100-150mm.

[0017] Preferably, the collection cover adopts a detachable connection structure, with its bottom connected to the liquid collection hopper via a flange and equipped with a sealing strip.

[0018] Beneficial effects: Improved product quality: The fan-shaped spray nozzle ensures better coverage of finishing liquid or dyeing liquid, resulting in better fabric uniformity. Furthermore, the downward spraying process, with the same amount of auxiliaries and finishing process, significantly increases the liquid retention rate on the fabric compared to the dip-dyeing process, and also improves fabric uniformity (significantly less color difference between the beginning and end compared to the pad-dyeing process), thus enhancing product quality.

[0019] Environmentally friendly and energy-saving: By using a low-liquid-feed and low-water dyeing method, the goal of clean production and low-carbon green environmental protection is achieved. Compared with traditional processes, the consumption of auxiliary agents is reduced by 30%, energy saving and consumption reduction reach 70%, and carbon emissions are reduced by 60%.

[0020] Optimize wastewater treatment: By using residual liquid tanks to recover residual dye liquor, small streams of high-concentration wastewater are centrally treated, and dyeing and printing wastewater is treated in stages from the source, which reduces the difficulty of water treatment and lowers the cost of wastewater treatment.

[0028] The following is in conjunction with the appendix Figure 1-5 The specific embodiments of this utility model will be described in further detail.

[0029] Example 1, by Figure 1-5 The present invention provides a spray-type fabric surface treatment machine, including a suction hood 1, a VOC pipe 2, a collection hood 3, a liquid collection hopper 4, a fabric inlet 5, a fabric outlet 6, a spray pipe 7, and a spray nozzle 8.

[0030] The suction hood 1 has a fabric inlet 5 and a fabric outlet 6 on its two sides respectively;

[0031] VOC pipe 2 is connected to one side of the top of the suction hood 1;

[0032] A collection hood 3 is connected to the bottom of the suction hood 1, and a liquid collection hopper 4 is provided at the bottom of the collection hood 3;

[0033] Several spray pipes 7 are horizontally arranged inside the suction hood 1 and perpendicular to the direction of fabric travel;

[0034] The nozzles 8 are arranged in an array at the bottom of each spray pipe 7. The nozzles 8 have a spray angle of 0°-110°, and the spray surfaces of adjacent nozzles 8 form a continuous atomized area.

[0035] The suction hood 1 has a fabric inlet 5 and a fabric outlet 6 on both sides, which is the core area for fabric treatment. Its function is to provide a relatively enclosed space for fabric surface treatment, ensuring that the liquid spraying process is not disturbed by the outside world, and at the same time, it works with the suction system to collect the waste gas generated during the process.

[0036] VOC pipe 2 is connected to one side of the top of the exhaust hood 1. It is responsible for transporting the waste gas containing volatile organic compounds generated during the treatment process to the subsequent treatment equipment, which meets environmental protection requirements and effectively reduces pollution to the environment.

[0037] The collection hood 3 is connected to the bottom of the suction hood 1, and a liquid collection hopper 4 is provided at its bottom. The collection hood 3 is used to collect excess liquid during the spraying process, which is convenient for recycling and reuse, while preventing liquid splashing and ensuring a clean working environment.

[0038] The bottom of the liquid collecting hopper 4 has a V-shaped structure with an inclination angle of 30°-60°, and is equipped with a guide channel and a drain port. The V-shaped structure design facilitates the collection and discharge of liquid, and the guide channel further guides the liquid flow to the drain port, making it convenient to centrally collect and treat excess treated liquid.

[0039] Several spray pipes 7 are arranged horizontally inside the suction hood 1 and perpendicular to the fabric travel direction. There are 3-5 groups of spray pipes 7 arranged along the fabric travel direction, and the spacing between each group of spray pipes 7 is 150-300mm. This layout can achieve comprehensive and uniform spray treatment on the fabric surface.

[0040] The nozzles 8 are arranged in an array at the bottom of each spray pipe 7. Each nozzle 8 has a spray angle of 0°-110°, and the spray surfaces of adjacent nozzles 8 form a continuous atomized area, ensuring that the fabric surface is uniformly covered with the treatment liquid. The preferred spray angle of the nozzles 8 is 90°-110°, and the spray axis of each nozzle 8 forms an inclination angle of 15°-45° with the horizontal plane. This angle setting allows the treatment liquid to be sprayed onto the fabric surface at the optimal angle and range, improving the treatment effect. The center-to-center distance between adjacent nozzles 8 is 80-120mm, and the atomization coverage diameter of each nozzle 8 is 100-150mm. This precise nozzle layout and parameter settings ensure the uniformity and efficiency of the spray.

[0041] The collection hood 3 adopts a detachable connection structure, and its bottom is connected to the liquid collection hopper 4 via a flange and is equipped with a sealing strip. The detachable connection facilitates the installation, maintenance and cleaning of the equipment, while the sealing strip ensures the sealing of the connection and prevents liquid and exhaust gas leakage.

[0042] Working Principle: In use, the fabric enters the suction hood 1 through the fabric inlet 5. The suction hood 1 creates a relatively enclosed space for the processing, greatly reducing interference from external airflow and other factors on the liquid spraying process. Simultaneously, the suction system activates, generating negative pressure to collect the waste gas produced during the process. This waste gas contains volatile organic compounds (VOCs), which are transported to specialized waste gas treatment equipment via a VOC pipe 2 connected to the top side of the suction hood 1, thereby meeting environmental protection requirements and reducing environmental pollution.

[0043] The fabric entering the suction hood 1 is subjected to a spray system consisting of spray pipes 7 and nozzles 8. Several spray pipes 7 are horizontally arranged inside the suction hood 1, perpendicular to the fabric's direction of travel. There are 3-5 groups of spray pipes 7 along the fabric's direction of travel, with a spacing of 150-300mm between each group. This arrangement ensures that the fabric surface is uniformly sprayed from different positions and angles. Nozzles 8 are arranged in an array at the bottom of each spray pipe 7, with a spray angle range of 0°-110°. The spray surfaces of adjacent nozzles 8 are interconnected, forming a continuous atomized area, thus ensuring that the fabric surface is fully and uniformly covered by the treatment liquid. The optimal spray angle for the nozzles 8 is 90°-110°, and the spray axis of each nozzle 8 forms an angle of inclination of 15°-45° with the horizontal plane. With this angle setting, the treatment liquid can be sprayed onto the fabric surface at the most suitable angle and coverage, significantly improving the treatment effect. The center-to-center distance between adjacent nozzles 8 is controlled at 80-120mm, and the atomization coverage diameter of each nozzle 8 is 100-150mm. This precise nozzle layout and parameter settings further ensure the uniformity and efficiency of the spraying process.

[0044] During the spraying process, excess treatment liquid is inevitable. At this point, the collection hood 3, connected to the bottom of the suction hood 1, comes into play. It collects this excess liquid, preventing it from splashing everywhere, maintaining a clean working environment, and facilitating subsequent recycling of the treatment liquid. The collection hopper 4 at the bottom of the collection hood 3 has a V-shaped bottom with an inclination angle of 30°-60°, and is equipped with a guide channel and a drain port. The V-shaped structure allows the liquid to naturally converge to the bottom, while the guide channel further guides the liquid flow to the drain port, facilitating the centralized collection and treatment of excess treatment liquid.

[0045] The collection hood 3 adopts a detachable connection structure, with its bottom connected to the liquid collection hopper 4 via a flange, and a sealing strip installed at the connection point. This detachable connection greatly facilitates the operation of the equipment during installation, daily maintenance, and cleaning, while the sealing strip effectively ensures the seal at the connection point, preventing liquid and exhaust gas leakage and ensuring the environmental friendliness and stability of the entire treatment process. After a series of treatments, the fabric is output from the fabric outlet 6, completing the entire surface treatment process.

[0046] Beneficial effects: Improved product quality: The fan-shaped spray nozzle ensures better coverage of finishing liquid or dyeing liquid, resulting in better fabric uniformity. Furthermore, the downward spraying process, with the same amount of auxiliaries and finishing process, significantly increases the liquid retention rate on the fabric compared to the dip-dyeing process, and also improves fabric uniformity (significantly less color difference between the beginning and end compared to the pad-dyeing process), thus enhancing product quality.

[0047] Precision production and cost control: By using CNC technology, the accuracy is higher and the dye spraying is more precise, achieving low-liquid-feed and low-bath-ratio dyeing, which can not only clean production but also save costs.

[0048] Environmentally friendly and energy-saving: By using a low-liquid-feed and low-water dyeing method, the goal of clean production and low-carbon green environmental protection is achieved. Compared with traditional processes, the consumption of auxiliary agents is reduced by 30%, energy saving and consumption reduction reach 70%, and carbon emissions are reduced by 60%.

[0049] Optimize wastewater treatment: By using residual liquid tanks to recover residual dye liquor, small streams of high-concentration wastewater are centrally treated, and dyeing and printing wastewater is treated in stages from the source, which reduces the difficulty of water treatment and lowers the cost of wastewater treatment.

[0050] Intelligent management: Intelligent equipment, convenient operation, and digital control facilitate efficient management and help enterprises transform into digital factories.

[0051] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
