Description

Technical Field

[0001] The invention relates to a pellet machine, in particular to a humidifying, drying and cooling integrated pellet machine. Background Art

[0002] In the textile industry, fabrics are subjected to processes such as napping, combing and shearing, and then are subjected to pilling to make the disordered fluff on the surface of the fabric curl into granules. Currently, the most commonly used pilling machine is a pilling machine, which is mainly used for pilling treatment of fabrics such as artificial fur, acrylic, and blankets. After high-temperature friction, the shrinkage fibers of the fabric are deformed, and the fluff on the surface of the fabric curls naturally, giving it a natural wool style, making it soft and elastic, thereby improving the quality of the product itself.

[0003] However, when using the existing pelletizer, the fabric must first be rolled at a certain humidity and temperature. The traditional humidification method is to spray steam. The steam has a certain temperature, so the fabric can be directly rolled. After rolling, it is dried. The drying process is done through a steam radiator, and then cooled down. The existing steam is provided by a thermal power plant, which has a high cost. At the same time, the transmission pipeline is long, and the steam temperature will be lost, generally about 100°C, which cannot meet the use temperature of various fabrics. In addition, the pelletizer cannot be used in places without steam supply, which brings limitations to the site selection of manufacturers.

[0004] The existing drying method uses natural gas to heat the air, such as patent No. 201821833035, named natural gas granulator. It can be seen from the disclosed technical solution that it has low energy consumption cost and can control the drying temperature. However, it still uses steam provided by the thermal power plant during the humidification process. In addition, the heater is located outside, its size is large, and the external temperature is high, which brings harm to the operator. Summary of the invention
