Description
Technical Field
The invention relates to the technical field of heat treatment kilns, in particular to a roller way kiln broken roller detection system and a roller way kiln broken roller detection method.
Background
Roller kilns, also known as roller hearth kilns, are continuous firing tunnel kilns that use the rotatory fire-resistant roller as the delivery vehicle, and the product (material) is placed on many horizontal interval arrangement's roller, leans on the rotation of roller to order about the product through the furnace of roller kilns to accomplish the sintering. In the actual operation of the roller kiln, the roller breakage phenomenon is likely to occur, the roller rod needs to be replaced in time, otherwise, the transmission system is not smooth in operation, even the roller is continuously broken, and the accident of the arch kiln is caused in serious conditions. Therefore, roller kilns are generally equipped with a roll bar breakage detection system.
At present, two schemes are mainly adopted for roll breakage detection and identification, the first scheme is that roll breakage is judged by detecting the tilting of roll rods based on the tilting of most roll rods after breakage, and the feasibility degree of the scheme is insufficient through actual inspection because the roll rods are not tilted under the condition of roll breakage, so that the problem of insufficient reliability exists. The second is to detect whether the roller rod rotates at the driven end of the roller rod to judge whether the roller rod is broken, because the roller kiln drives the roller rod to rotate through a driving system at one end, when the roller rod is broken, the broken end loses the transmission of the torque of the driving end, and the actual performance is that the roller rod does not rotate any more. The detection and identification scheme is a mainstream roll breakage identification method.
For the second roll breakage identification scheme, the current main technical route is based on various sensors and detection devices, detects whether the driven end of the roll rod rotates periodically, determines that the roll is broken if the driven end does not rotate periodically, then transmits a signal to a detection control device, and the detection control device outputs an alarm signal. The accurate detection and alarm of each roller are realized, a detection unit is required to be configured for each roller, each detection unit comprises an independent wiring, a sensor (detection device) and a control point position of a detection control device, the number of the rollers of a roller kiln is usually 500-800, the wiring is complex, the assembly and maintenance difficulty is high, the control difficulty is high, and the cost is high. Therefore, the existing roll breakage detection system basically adopts a scheme of sectional roll breakage detection, namely, a plurality of roll rods are divided into a plurality of sections, a rod assembly is adopted to synchronously detect the roll rods in the sections, when one roll rod in the section is broken, the roll rod assembly can detect the broken roll rod, and then a field inspection worker arrives at the position of the section to check which roll rod is broken and replace the broken roll rod. However, the partitioned detection scheme cannot accurately and timely detect each specific roller rod, manual assistance is still needed, the automation and intelligence degrees are low, and the labor cost is high.
