Device for recovering waste heat of printing and dyeing equipment

Abstract

The invention relates to the technical field of printing and dyeing equipment, and discloses a device for recovering waste heat of the printing and dyeing equipment. The device comprises the printingand dyeing equipment. According to the device for recovering waste heat of the printing and dyeing equipment, hot air inside the printing and dyeing equipment is blown into a fixed block through a fan, and then pushes a helical sheet to drive a rotating sleeve to rotate, and the rotating sleeve and the helical sheet helically introduces the hot air in turn, so that the entrance speed of the hot air is reduced effectively. In addition, the hot air impacts a rotary fan blade, and then the rotary fan blade, a movable block and a buffer spring co-act to achieve a further buffering effect. According to the device, the flow rate of the hot air entering a waste heat recovery device is reduced through a series of mechanical structures, so that the hot air remains inside the waste heat recovery device for a long time; the waste heat can be fully recovered; and higher waste heat recovery efficiency is achieved. In addition, a rotary block is in close fit with a guide groove through a pressure spring and a top plate.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing equipment, in particular to a device for recovering waste heat of printing and dyeing equipment. Background technique [0002] Printing and dyeing, also known as dyeing and finishing, is a processing method and a general term for pretreatment, dyeing, printing, finishing and washing; the undergraduate dyeing and finishing major has now been incorporated into the light chemical engineering major; as early as six or seven thousand In the Neolithic Age years ago, our ancestors were able to dye linen red with hematite powder. The primitive tribes living in the Nomuhong area of ​​the Qaidam Basin in Qinghai could dye wool yellow, red, brown and blue. In the Shang and Zhou dynasties, the dyeing technology continued to improve, and full-time officials "dyeers" were set up in the palace handicraft workshops to "hand-dye grass" to manage the dyeing production, and the dyed colors were also exce...
