TECHNICAL FIELD
[0001] The utility model relates to spinning monomer suction technical field especially, relates to a kind of efficient monomer suction pressure detection device. BACKGROUND
[0002] Polyamide 6 spinning process is by spinneret to melt high polymer is sprayed, and cooling forming nascent fiber. Because high polymer contains a certain amount of monomer and oligomer, monomer and oligomer are precipitated in high-temperature molten state, form smoke. If monomer cannot be removed in time, it will have great influence on product physical property index. Therefore, monomer suction device is important equipment when polyamide 6 is spun, can remove the monomer formed by oligomer in the process of chip melting and extruding into silk thread by the negative pressure formed by water jet, improve the quality of silk thread, reduce caprolactam concentration in working environment. The existing monomer suction device includes suction hood, monomer suction pipe and hose connected between suction hood and monomer suction pipe. Spinning monomer circulating water is transported to production spinning position by pipeline through water pump, and water is sprayed into monomer suction pipe located at production spinning position after nozzle. Negative pressure is generated in monomer suction pipe during water flow, and smoke is sucked into monomer suction pipe after passing through suction hood.
[0003] The existing suction system often lacks precise suction force detection mechanism, and under the condition of not affecting production, the suction force can only be judged by the size of monomer suction water pressure, but the same size of monomer suction water pressure cannot represent the same size of monomer suction force, so that the suction force of each spinning position is greatly different, which affects product quality. In addition, because spinning specifications are different, the requirement for monomer suction force is also different. If monomer suction force is accurately measured, monomer suction hose needs to be pulled out, but such operation will affect production process. UTILITY MODEL CONTENTS
