AI Technical Summary

Technical Problem

In polyester production, PTA chain plate conveying device is prone to chain disconnection, resulting in unstable transportation and difficult maintenance, which affects production continuity and product quality.

Method used

A PTA chain chain off-chain alarm shutdown device is designed, including a off-chain alarm mechanism and an off-chain shutdown control mechanism. By monitoring the meshing status of the chain and the octagonal gear in real time, the triggering interlock switch is triggered to be disconnected after the chain is found, and the conveyor device is stopped and an alarm signal is issued.

Benefits of technology

It realizes timely detection and shutdown of the machine for maintenance, avoids chain breakage and motor bearing wear, reduces maintenance difficulty and time, and ensures the stability and product quality of PTA conveying and polyester production.

Abstract

The invention discloses a PTA (pure terephthalic acid) chain plate chain separation alarm shutdown device which comprises a conveying pipeline, a control motor, a chain plate and an octagonal gear, the chain plate and the octagonal gear are connected in series through a chain, a chain separation alarm mechanism is arranged on the inner side of the top of the conveying pipeline, and a chain separation shutdown control mechanism used for controlling shutdown of the conveying device is further arranged on the outer side of the conveying pipeline. An interlocking switch is arranged between the chain disengaging shutdown control mechanism and the chain disengaging alarm mechanism, the chain disengaging alarm mechanism is used for monitoring meshing of the chain and the octagonal gear in real time, and when the chain and the octagonal gear are disengaged, the chain disengaging alarm mechanism triggers the interlocking switch to be switched off. And therefore, the chain separation shutdown control mechanism is controlled to stop the conveying device and send out an alarm signal. The problems that in the process that PTA raw materials are conveyed to a PTA stock bin through a chain plate conveying device, a conveying chain is disengaged and cannot be found in time, and shutdown cannot be achieved can be solved, the operation stability and integrity of the conveying device are guaranteed, maintenance is more convenient and timely, and the production stability is good.
