Broken bar detection device, broken bar automation monitoring system and roller kiln

Abstract

The invention provides a broken bar detection device. The device comprises a transmission roller bar, one end of the transmission roller bar is fixedly connected with a rotating shaft which extends outwards, the tail end of the rotating shaft is fixedly connected with a trigger block suitable for rotation along with the rotating shaft, the outer side of the trigger block is fixedly provided with asignal generator corresponding to the trigger block, when the transmission roller bar rotates, the rotating shaft is driven to rotate, the trigger block is driven to rotate, and when the trigger block rotates to make contact with the signal generator, the signal generator generates a detection signal. Through the contact type broken bar detection device, multiple defects existing in the prior artcan be effectively overcome; in addition, the invention further provides a broken bar automatic monitoring system based on the contact type broken bar detection device and a roller kiln with the broken bar automatic monitoring system based on the contact type broken bar detection device.

Description

technical field [0001] The invention relates to a broken rod detection device, a broken rod automatic monitoring system and a roller kiln. Background technique [0002] Chinese patent 201610772497.8 discloses a roller kiln partition broken roller detection method and system, which belongs to the field of lithium battery material sintering. It includes setting two induction switches in the induction area under the driven side of any roller that can sense the follow-up original, which are respectively recorded as the first induction switch and the second induction switch; building a series circuit to connect all the first induction switches in the partition In series, build a parallel circuit to connect all the second induction switches in the partition in parallel; at the same time, detect whether the on-off of the series circuit and the parallel circuit is periodically changed; When it changes, it is judged that the partition is broken. On the basis of this detection metho...

Problems solved by technology

At the same time, this non-contact (electromagnetic induction) has its disadvantages, as follows: first, the magnetic induction switch is prone to failure when the temperature is too high; second, the magnetic induction switch (non-contact) is effective within a certain distance, if two The distance between the root rollers is small, which is prone to misjudgment of alarms; third, it requires more equipment investment costs, such as sensors and PLC IO access resources, especially for kilns with large output and long-distance transportation, which consume resources More
