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 firstly discloses a roller kiln zone broken roller detection system, including:

[0033] The follower element corresponding to each roller bar is arranged on the driven side of the roll bar, and two induction switches are respectively arranged in the sensing area under each driven side that can sense the follower element, which are respectively recorded as the first induction switch. switch and a second sensor switch.

[0034] A series circuit, in which all the first induction switches in any partition are connected in series.

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

[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. It is judged that the partition is broken.

[0037] Wherein, in a normal state before th...

Embodiment 2

[0050] Corresponding to the above-mentioned embodiment 1, this embodiment discloses a method for detecting broken rollers in a roller kiln zone, such as Figure 9 shown, including:

[0051] Step S1, setting two induction switches respectively in the induction area capable of inducting the follower element under the driven side of any roller, which are respectively denoted as the first induction switch and the second induction switch. Wherein, in a normal state before the start of any partition roller bar, the relative positional relationship between each follower element and the corresponding first and second induction switches is consistent.

[0052] Step S2, building a series circuit to connect all the first induction switches in the partition in series, and building a parallel circuit to connect all the second induction switches in the partition in parallel.

[0053] Step S3: Simultaneously detect whether the on-off of the series circuit and the parallel circuit is periodi...

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 of lithium battery materials, in particular to a method and system for detecting broken rollers in a roller kiln for sintering positive electrode materials of lithium batteries. Background technique [0002] At present, the anode materials of domestic lithium batteries basically use the roller kiln sintering process. During the long-term high-temperature operation of the roller kiln, the rollers will break, and the drive motor will still drive other rollers to run normally after the roller breaks. Therefore, if there is no If the broken rollers are found and replaced in time, the sintered material will be blocked in the roller kiln, resulting in kiln blockage, which will further cause a larger area of ​​broken rollers and cause huge losses to the factory. [0003] Therefore, a reliable broken roll detection technology is a necessary guarantee for the stable operation of the roller kiln. The existing conv...
