Problems solved by technology

It has the following disadvantages: 1. It is impossible to monitor all the rollers; 2. The induction detection element is a temperature sensitive element, and its working life is short under high temperature conditions, so it is not suitable for the high temperature working environment of the roller kiln site; 3. Each detection zone is relatively Isolation, it is impossible to realize the overall monitoring of multiple areas, the monitoring efficiency is low, and it is not suitable for the implementation and promotion of modern factories

Embodiment 1

[0032] The embodiment of the present invention first discloses a roller kiln zone broken roll detection system, which includes:

[0033] The follower elements corresponding to each roller one-to-one are arranged on the driven side of the roller, and two induction switches are set in the sensing area below each of the driven sides that can sense the follower elements, which are respectively marked as the first induction Switch and second inductive switch.

[0034] The series circuit is connected in series with all the first inductive switches in any partition.

[0035] The parallel circuit is connected in parallel with all the second inductive switches in any partition.

[0036] The detection result processing unit is used to simultaneously detect whether the on-off of the series circuit and the parallel circuit changes periodically after the corresponding partition is started. When the on-off of any partitioned series circuit or parallel circuit is detected acyclically, Determine the...

Embodiment 2

[0050] Corresponding to the above-mentioned embodiment 1, this embodiment discloses a method for detecting broken rolls in roller kiln zones, such as Picture 9 Shown, including:

[0051] Step S1, two induction switches are respectively arranged in the induction area below the driven side of any roller that can sense the driven original, which are respectively denoted as the first induction switch and the second induction switch. Wherein, in the normal state before any zone roller is activated, the relative position relationship between each follower and the corresponding first and second induction switches is consistent.

[0052] Step S2: Build a series circuit to connect all the first inductive switches in the partition in series, and build a parallel circuit to connect all the second inductive switches in the partition in parallel.

[0053] Step S3: At the same time, it is detected whether the on-off of the series circuit and the parallel circuit changes periodically, and when it ...

Abstract

The invention discloses a roller kiln subarea broken roller detection method and system and belongs to the field of lithium battery material sintering. The roller kiln subarea broken roller detection method comprises the steps that two inductive switches are arranged in an induction area which is arranged below the driven side of any roller bar and can induct a follow-up element, and the two inductive switches are denoted as the first inductive switch and the second inductive switch; a series circuit is built so that all the first inductive switches in subareas can be connected in series, and a parallel circuit is built so that all the second inductive switches in the subareas can be connected in parallel; whether connection and disconnection of the series circuit and the parallel circuit are in a periodical change mode is detected at the same time; and when connection and disconnection of the series circuit and the parallel circuit in any subarea are detected to be not in the periodical change mode, the situation that a roller in the subarea is broken is judged. The corresponding detection system is built based on the detection method, accordingly, an alarm is given timely and accurately, and the subarea where the broken roller is located is fed back; and a maintenance man can go to the subarea where the broken roller is located to find out the broken roller and replace the broken roller in time, meanwhile, overall monitoring of multiple roller kiln roller bars can be achieved advantageously, and the whole operating efficiency is improved.

Description

Technical field [0001] The invention relates to the field of sintering lithium battery materials, and in particular to a method and a system for detecting broken rollers in a roller kiln for sintering lithium battery anode materials. Background technique [0002] At present, the domestic lithium battery cathode material basically uses the roller kiln sintering process. During the long-term high temperature operation of the roller kiln, the roller will break, and the drive motor will still drive the other rollers to operate normally after the roller is broken. Find and replace the broken rollers in time. The sintered materials will jam in the roller kiln, which will cause the kiln to jam, which will further cause a larger area of ​​roller fracture accidents and cause huge losses to the factory. [0003] Therefore, reliable broken roll detection technology is a necessary guarantee for the stable operation of roller kilns. The existing conventional detection method is to detect the r...
