Description

Technical Field

[0001] This application belongs to the technical field of fabric processing equipment, and in particular relates to a water-saving circulating water spray dyeing device. Background Technology

[0002] With the development of the times, people have higher and higher requirements for the aesthetics of the fabric products they use in their lives. In order to make the fabric present different colors, it is necessary to dye the fabric. However, the fabric dyeing equipment on the market now has a high demand for water resources. In order to save water, a water-saving dyeing equipment is needed to increase the utilization rate of water resources.

[0003] For example, Chinese patent CN218932571U discloses a dyeing device for polyester yarn, including a box body. A dyeing box is fixedly installed on the inner wall of the box body. A rotating rod is rotatably connected to the lower side of the inner wall of the dyeing box. A drying box is fixedly installed on the inner wall of the box body. A water pump is fixedly installed on the inner wall of the box body. A connecting pipe is fixedly installed at one end of the water pump. A water spray plate is installed at the outer end of the connecting pipe. An inclined plate is fixedly installed at one end of the water spray plate. A water inlet pipe is fixedly installed at the outer end of the water pump. A fan is fixedly installed on the inner wall of the box body. A heating rod is fixedly installed at the lower end of the fan. An exhaust pipe is fixedly installed at the outer end of the box body.
