Yarn dyeing machine main pump structure with extremely low bath ratio

Abstract

The invention discloses a yarn dyeing machine main pump structure with an extremely low bath ratio. The yarn dyeing machine main pump structure with the extremely low bath ratio comprises a liquid return pipeline, a return flow liquid storage cavity, a liquid discharging inlet, a liquid discharging pipeline and a separating plate. The liquid return pipeline and the liquid discharging inlet are in butt joint with a liquid inlet and a liquid outlet of a three-level impeller of a yarn dying machine respectively, and dying liquid passes through the liquid discharging inlet, enters the liquid discharging pipeline and then enters a yarn frame dying liquid flow channel under the function of the three-level impeller. The dying liquid dip dyes yarn to be dyed and then enters the return flow liquid storage cavity through a dying liquid collecting tray, and the dying liquid then enters the three-level impeller through the liquid return pipeline to carry out recirculation. The separating plate is formed by an arc plate and an inner rib plate through welding and separates a liquid discharging channel and a liquid return channel of the dying liquid. The arc plate is connected on the outer wall of the liquid discharging pipeline in a sleeved mode, and the inner rib plate is sleeved on the outer wall of the liquid return pipeline in a sleeved mode. The dying liquid flows into the liquid discharging pipeline though a notch in the middle of the separating plate. The yarn dyeing machine main pump structure with the extremely low bath ratio is simple in structure, easy to manufacture and capable of enabling a yarn dying machine to reach the extremely low bath ratio of 1:2.5, enables discharging of liquid waste to be lower, is more environmentally friendly, and can improve economic benefit.

Problems solved by technology

[0007] Although the above-mentioned patents have achieved an ultra-low bath ratio of 1:3, there is still room for improvement. Further research is needed to optimize the structure of the yarn dyeing machine so as to further reduce the bath ratio, reduce waste liquid discharge, and improve the economic benefits of yarn dyeing.
