Problems solved by technology

On the one hand, a large number of monomers are suspended around the tow, and these monomers will adhere to the tow when the tow flows downward, which seriously reduces the quality of the tow; on the other hand, the monomer escapes into the air, It is easy to cause environmental pollution and is not conducive to the health of the staff

Abstract

The invention discloses an individual suction device which comprises an upper flange (1), a lower flange (2), an inner shell (5) connected on the lower shell (2), an outer shell (4) connected between the upper flange (1) and the lower flange (2) and a suction pipe (6) connected on the outer shell (4). A passage (50) for accommodating a tow (81) is formed inside the inner shell (5), an inlet (51) is arranged between the inner shell (5) and the upper flange (1), and the suction pipe (6) is connected with a suction pump. Individuals volatilized from the tow are sucked in from an inlet between the inner shell and the upper flange through the suction pipe and discharged from the suction pipe, so that impact on quality of the tow caused by the fact that suspended individuals are attached on the tow is prevented; the individual suction device further comprises a steam pipe, individuals accumulated in the device can be removed, and the individual suction device is more reliable and convenient to use.

Description

technical field [0001] The invention relates to the field of spinning equipment, in particular to a monomer suction device. Background technique [0002] At present, with the continuous expansion of spinning varieties, the market demand for nylon staple fiber is increasing day by day. During the production of nylon staple fiber, the molten nylon melt needs to be sprayed from the spinneret. Due to the chemical composition and physical properties of nylon itself, the monomers and oligomers in the nylon melt will volatilize, making the melt from the spinneret A large amount of monomer floating matter will be produced after the fine stream of tow is ejected from the wire plate, forming a large amount of smoke. On the one hand, a large number of monomers are suspended around the tow, and these monomers will adhere to the tow when the tow flows downward, which seriously reduces the quality of the tow; on the other hand, the monomer escapes into the air, It is easy to cause envir...
