Description

Technical Field

[0001] The utility model relates to the technical field of sizing machines, in particular to a waste heat recovery device for sizing machines. Background Art

[0002] The sizing machine is a process for sizing the yarn before weaving. It is used to improve the toughness, strength and surface smoothness of the yarn. It is an indispensable process for treating the yarn before weaving. When sizing the yarn, the slurry in the sizing tank needs to be heated to 90℃-95℃ with steam.

[0003] In the prior art, Chinese Patent Publication No. CN220166443U discloses a slurry tank heating device for a sizing machine, including a frame and a slurry tank, wherein a heating interlayer is provided in the bottom and / or the surrounding side walls of the slurry tank, and the heating interlayer steam trap and the hot steam recovery pipe are connected to the high-temperature steam exhaust port of the drying equipment. By introducing the high-temperature water vapor discharged from the drying room into the interlayer of the slurry tank to heat the slurry, the amount of steam required for slurry heating is significantly reduced, the high-temperature water vapor discharged from the drying room is recycled and utilized, and the unnecessary loss and waste of heat from the high-temperature water vapor is avoided. At the same time, by reducing the use of traditional steam, it is beneficial to control the temperature of the slurry, and the concentration and viscosity changes of the slurry caused by the mixing of condensed water are greatly reduced, which saves energy while ensuring the stability of sizing. After the heat exchange is completed in the tank body, the high-temperature water vapor with a lowered temperature forms condensed water, which returns to the water storage tank and is used for slurry adjustment or as a boiler to supplement hot water.

[0004] However, when the utility model is actually used, the condensed water formed has waste heat due to the contact with steam. The device sends the warm condensed water into the water storage tank, which may cause waste of water temperature waste heat. When sizing the yarn, it is not convenient to directly recycle the steam and condensed water at the same time, so improvement is needed. Utility Model Content
