Description

Technical Field

[0001] This utility model relates to the field of textile processing, and in particular to a steam pre-shrinking machine for textile fabrics. Background Technology

[0002] In textile dyeing and finishing processes, pre-shrinking is a key finishing process for improving fabric dimensional stability and enhancing finished product quality. Its purpose is to shrink the fabric before it is worn, thereby reducing the shrinkage rate of the finished product after washing. Steam pre-shrinking is one of the widely used technologies. Its principle is to use high-temperature steam to cause textile fibers to absorb moisture, expand, and relax, thereby releasing the internal stress generated during spinning, weaving, and dyeing and finishing, achieving the pre-shrinking effect. Existing steam pre-shrinking machines typically include two main functional areas: steam humidification and drying / setting. In the steam humidification stage, the steam generated by the steam generator directly acts on the fabric. After pre-shrinking, a large amount of high-temperature waste steam is often directly discharged into the environment, which not only wastes a large amount of heat and water resources but also contradicts the current requirements of energy-saving and environmentally friendly industrial development. Therefore, there is an urgent need to develop a steam pre-shrinking machine for fabrics that can effectively recover and utilize waste heat from the production process, achieving cascaded energy utilization and reducing energy consumption.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings: Example

[0016] A steam pre-shrinking machine for textile fabrics, such as Figure 1-3 As shown, the device includes a housing 1, a conveyor belt 2 mounted on the housing 1 for conveying textile fabrics; a feeding roller is rotatably installed at the feed end of the housing 1; a steam cover 4 is installed at the upper end of the housing 1 near the feed end; inside the housing 1, a steam pan 5 is installed below the steam cover 4, and the steam pan 5 is fixedly installed in the cavity formed by the upper conveying surface and the lower return surface of the conveyor belt 2; a steam generator 6 is also installed inside the housing 1 below the steam pan 5 and fixedly connected to the housing 1; the steam generator 6 is fixedly connected to the steam pan 5 through a steam pipe 7; and a steam discharge pipe 8 is fixedly connected to the upper end of the steam cover 4. A steam cover 4 is provided on the upper part of the box 1, away from the feed end, and a drying cover 9 is also provided. A hot air conveying pipe 10 is fixedly connected to the top of the drying cover 9. An air distribution plate 11 is also provided inside the drying cover 9. One end of the hot air conveying pipe 10 extends through the drying cover 9 and is fixedly connected to the air distribution plate 11 inside the drying cover 9. Inside the box 1, an air receiving plate 12 is provided below the steam cover 4. The air receiving plate 12 is fixedly installed in the cavity formed by the upper conveying surface and the lower return surface of the conveyor belt 2. An exhaust pipe 13 extending to the outside of the box 1 is also fixedly connected to the lower end of the air receiving plate 12. A tubular heat exchanger 15 is provided on one side of the housing 1. The tubular heat exchanger 15 is provided with a hot steam inlet 16, a cooling outlet 17, a cold air inlet 18, and a hot air outlet 19. A water receiving tank 21 is provided on the lower side of the tubular heat exchanger 15. A water inlet 22 and an exhaust outlet 23 are respectively provided on both sides of the water receiving tank 21. The heat source inlet of the tubular heat exchanger 15 is fixedly connected to the steam exhaust pipe 8. The cooling outlet 17 is fixedly connected to the water inlet 22 of the water receiving tank 21. A fan 20 is fixedly installed at the cold air inlet 18. The hot air outlet 19 is fixedly connected to the hot air delivery pipe 10.

[0017] Working principle: The textile fabric is introduced by the feed roller at the inlet end and laid flat on the conveyor belt 2. The conveyor belt 2 transports the laid textile fabric. First, the textile fabric passes through the steam treatment zone. The steam generator 6 located at the bottom of the box 1 generates high-temperature steam, which is transported to the steam pan 5 through the steam pipe 7. The steam rises and penetrates the conveyor belt 2 evenly, humidifying and heating the textile fabric in all directions. This allows the fabric fibers to be fully wetted and relaxed, releasing internal stress and achieving the purpose of pre-shrinking. Excess steam is discharged directionally through the steam discharge pipe 8 at the top of the steam cover 4 with the assistance of the conveyor fan 20.

[0018] Subsequently, the moistened fabric, after being pre-shrunken by steam, enters the drying and shaping zone. Waste steam discharged from the steam exhaust pipe 8 serves as a heat source and is introduced into the tubular heat exchanger 15. Simultaneously, the fan 20 blows cold air from the environment into the cold air inlet 18 of the tubular heat exchanger 15. Inside the heat exchanger, the cold air undergoes non-contact heat exchange with the waste steam, absorbing heat and transforming into dry hot air. This hot air is then transported from the hot air outlet 19 through the hot air conveying pipe 10 to the drying cover 9. Under the action of the air distribution plate 11 inside the drying cover 9, the hot air is transformed into a uniform and stable airflow that blows downwards, efficiently drying the fabric on the conveyor belt 2 below, removing excess moisture, and allowing the fabric to be shaped after shrinkage, preventing it from becoming damp again.

[0019] After heat exchange, the waste steam condenses into water in the tubular heat exchanger 15 and flows into the water receiving tank 21 below through the cooling outlet 17. This recovered condensate is then transported back to the steam generator 6 through the return water pipe, realizing the recycling of water resources and saving energy and protecting the environment. Meanwhile, the waste gas carrying water vapor during the drying process passes through the fabric and conveyor belt 2 and is collected by the air receiving plate 12 located below the steam plate 5, and finally discharged from the system through the exhaust pipe 13.

The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0021] Although this disclosure has been described in detail with reference to exemplary embodiments, it is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes may be made thereto without departing from the scope of this disclosure.
