Description

Technical Field

[0001] This utility model relates to the field of dyeing technology, and in particular to a water-saving washing device for dyeing polyester and cotton. Background Technology

[0002] Polyester-cotton blends refer to a general term for fabrics made from a blend of polyester and cotton. In the dyeing process of polyester-cotton blends, washing is a crucial step, designed to remove excess dye, auxiliaries, and other impurities from the fabric surface. Traditional washing methods typically involve immersing the fabric in soaking tanks, each equipped with a press to squeeze out excess water and impurities. The fabric is then conveyed sequentially through multiple soaking tanks via a roller conveyor system, undergoing repeated soaking and squeezing to achieve the desired cleaning effect. However, this method has some problems. When the fabric first enters the first soaking tank, it has the highest concentration of dyes and impurities, causing the water in the first tank to quickly become thick and contain high concentrations of dyes and auxiliaries. This reduces the soaking effect because the fabric cannot effectively separate from the dyes and auxiliaries in the water. When the fabric enters the next soaking tank, it carries even more dyes and auxiliaries, further prolonging the washing process and leading to water waste. Utility Model Content

[0003] To overcome the shortcomings of the existing technology mentioned above, this utility model provides a water-saving washing device for polyester-cotton dyeing, which can reduce the use of clean water and reduce the waste of water resources.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a water-saving washing device for polyester-cotton dyeing, including a rinsing tank and multiple soaking tanks. The rinsing tank and soaking tank are arranged sequentially according to the feeding sequence. Feeding rollers and water-squeezing rollers are respectively arranged at both ends of the rinsing tank. Several conveying rollers are arranged in the rinsing tank. An upper rinsing frame and a lower rinsing frame are respectively arranged on the upper and lower sides of the conveying rollers. Several rinsing nozzles are arranged on the upper and lower rinsing frames. A rinsing drain outlet is also arranged on the rinsing tank. A filter device is arranged at the rinsing drain outlet inside the rinsing tank. A water storage device is arranged on one side of the rinsing tank. A nozzle water pump is arranged in the water storage device. The nozzle water pump is connected to a main water pipe. The main water pipe is connected to a branch pipe. The branch pipe is connected to the upper rinsing frame and the lower rinsing frame respectively.

[0005] Preferably, the immersion tank is provided with an immersion drain outlet and an immersion water inlet on one side. The immersion drain outlet is connected to a water pump, and the water pump is connected to a water pipe.

[0016] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0017] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0018] According to Figure…1- Figure 5 As shown, a water-saving washing device for polyester-cotton dyeing includes a rinsing tank 1 and multiple soaking tanks 2. The rinsing tank 1 is used to rinse the fabric, and the soaking tanks 2 are used to soak the fabric. The rinsing tank 1 and the soaking tanks 2 are arranged sequentially according to the feeding sequence. Feeding rollers 11 and water-squeezing rollers 12 are respectively installed at both ends of the rinsing tank 1. Several conveying rollers 13 are also installed in the rinsing tank 1. Feeding rollers and water-squeezing rollers are also installed in the soaking tank 2. The fabric enters the rinsing tank 1 through the feeding rollers 11, then passes through the feeding rollers 13, exits the rinsing tank 1 through the water-squeezing rollers 12, and the water is discharged by the water-squeezing rollers 12. Then, it enters the soaking tank 2 through the feeding rollers 11 on the soaking tank 2. Upper rinsing frames 1 are respectively installed on the upper and lower sides of the conveying rollers 13. The upper and lower rinsing racks 14 and 15 are equipped with several rinsing nozzles 16. In this application, two sets of upper and lower rinsing racks 14 and 15 are provided to rinse the fabric and remove impurities, dyes and auxiliaries. The rinsing tank 1 is also equipped with a rinsing drain outlet 17. A filter device 3 is provided at the rinsing drain outlet 17 inside the rinsing tank 1 to filter the impurities washed down. A water storage device 4 is provided on the outer side of the rinsing tank 1. A nozzle water pump 41 is provided in the water storage device 4. The nozzle water pump 41 is connected to a main water pipe 42. The main water pipe 42 is connected to a branch pipe 43. The branch pipe 43 is connected to the upper rinsing rack 14 and the lower rinsing rack 15 respectively.

[0019] The immersion tank 2 is provided with an immersion drain outlet 21 and an immersion water inlet 22 on one side. A water pump 23 is connected to the immersion drain outlet 21, and a water pipe 24 is connected to the water pump 23. The water pipe 24 is connected to the immersion water inlet 22 on the previous immersion tank 2. The water pipe 24 on the immersion tank 2 near the rinsing tank 1 is connected to a water storage device 4. During operation, the water in the immersion tank 2 gradually becomes clearer as the fabric is processed, depending on the feeding direction. The water pump 23 and water pipe 24... The relatively clean water from the last set of immersion tanks 2 is then transferred back to the previous set of immersion tanks 2 with a higher degree of contamination, thereby effectively reducing the water's contamination level. The water is then transferred to the water storage device 4. Subsequently, this water is introduced into the rinsing nozzles 16 by the nozzle pump 41 to rinse the fabric in the rinsing tank 1. The water storage device 4 is also equipped with a clean water pipe 44, which allows clean water to be added to neutralize the water if the contamination level in the immersion tanks 2 is too high.

[0020] The filtration device 3 includes a partition frame 31, which is positioned above the flushing drain outlet 17. A filter screen frame 32 is installed in the partition frame 31. The filter screen frame 32 is located on one side of the flushing drain outlet 17. A filter screen 33 is installed on the side of the filter screen frame 32 closest to the flushing drain outlet 17, and several filter holes 34 are provided on the other side. The filter screen 33 on the side closest to the flushing drain outlet 17 is used for fine filtration of impurities in the water; while several filter holes 34 are provided on the other side to allow sewage to enter the filter screen frame 32. The sewage first enters the filter screen frame 32 through the filter holes 34, and then impurities are intercepted when passing through the filter screen 33. The impurities remaining in the filter screen frame 32 can be removed by periodic cleaning.

[0021] The upper rinsing rack 14 and the lower rinsing rack 15 are inclined according to the path of the raw materials, and the rinsing nozzle 16 is set perpendicular to the ground, so that the water flow sprayed from the rinsing nozzle 16 can be inclined to rinse the fabric, thereby improving the rinsing effect.

[0022] This design is ingenious. By setting the first set of immersion tanks as rinsing tank 1, the fabric can be rinsed when it has the most impurities and dyes, effectively removing the impurities from the fabric. In rinsing tank 1, the fabric is directly impacted by a high-intensity water flow, which helps to quickly peel off and wash away surface impurities and dyes. Subsequent washing steps can be carried out more efficiently, reducing water consumption and wastewater generation, thereby optimizing the entire washing process. The installation of a water pump 23, water pipe 24, and water storage device 4 on one side of the immersion tank 2 further reduces the amount of clean water used, achieving a more environmentally friendly and sustainable washing process.

[0023] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
