Jet combustion device for yarn singeing machine

Abstract

The invention discloses a jet combustion device for a yarn singeing machine, and aims to solve the problems of insufficient combustion, a low flame temperature and short and instable flames of the conventional combustion device. The center of a fire distributor in the middle of an air supply support of the device is provided with a combustion channel for yarn singeing; the front surface of the air supply support and the circumferential wall of the fire distributor are provided with a vertically through yarn feeding and discharging channel; the circumferential wall of the fire distributor is provided with ventilation combustion holes which are formed radially and are communicated with a mixed gas inlet through the air supply support; the wall of a flame guiding pipe which is arranged over and adjacent to the fire distributor is provided with a vertically corresponding yarn feeding and discharging channel and a ventilation hole; the flame guiding pipe is fixed at the back of a protective mask; the middle of the protective mask is provided with a corresponding yarn feeding and discharging channel; the edge of the protective mask is provided with a hinge for resetting the protective mask; an upper yarn guiding ring and a lower yarn guiding pipe are arranged on the axis lines of the fire distributor and the flame guiding pipe; and the inside of the air supply support has a cavity structure, and the air supply support is in Morse taper fit with the fire distributor.

Description

technical field [0001] The invention belongs to the technical field of yarn singeing machines, and in particular relates to a jet burning device which uses a mixed gas flame to burn off yarn hairiness. Background technique [0002] The mixed gas flame combustion device is one of the core components of the yarn singeing machine, and it is where the mixed gas burns. Whether its structure is reasonable is an important factor to determine the quality of the yarn processed by the yarn singeing machine. Due to the unreasonable structure and insufficient combustion of the existing combustion device of the yarn singeing machine, dust is easy to accumulate on the yarn, which affects the quality of the yarn, and the temperature of the combustion flame is not high, and the flame is short so that the combustion of the yarn singeing The channel is short, the flame cannot be used effectively, and the singeing efficiency is not high. At the same time, the burning device of the existing yar...

Problems solved by technology

Due to the unreasonable structure and insufficient combustion of the existing combustion device of the yarn singeing machine, dust is easy to accumulate on the yarn, which affects the quality of the yarn, and the temperature of the combustion flame is not high, and the flame is short so that the combustion of the yarn singeing The channel is short, the flame cannot be used effectively, and the singeing efficiency is not high. At the same time, the burning device of the existing yarn singeing machine has no protective parts, and the external environment has a great influence on the flame, causing the flame to be unstable from big to small, which seriously affects Quality of yarn singeing
