Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically to a signal loss prevention device for transmission rod assembly and a discharge machine for double-chamber kilns. Background Technology

[0002] The discharge machine (or ash discharger) is a key piece of equipment for controlling material conveying in lime kilns and is widely used in the conveying of finished lime in the metallurgical industry. In the dynamic calcination system of a double-chamber lime kiln, multiple sets of ash discharge devices are configured around the kiln body, and the finished lime is guided into the lower buffer bin through a timed discharge mechanism.

[0003] As a transmission component of the feeder, the transmission rod assembly is one of the core components of the feeder. It adopts a high-quality steel plate welded structure and has the advantages of small size and light weight. In addition to ensuring the normal and stable operation of the feeder, it also needs to transmit the position signal of the feeder to the main control to realize the automation function.

[0004] However, in actual production, the transmission rod assembly may experience signal loss, causing the main controller to lose the position of the equipment, which in turn leads to the shutdown of the entire system. In the failure modes of the transmission rod assembly, abnormal rotation of the hydraulic cylinder accounts for 67.3±2.8%. This type of failure chain reaction manifests as follows: the circumferential displacement of the hydraulic cylinder causes the induction iron to deflect, triggering the proximity switch signal failure (response time t>500ms), which in turn leads to inaccurate periodic coordinated action between the actuation system and the ash removal device.

[0005] The above-mentioned abnormal rotation failure problem has not been solved, and manual adjustment by workers is required before normal operation can be achieved. Generally, adjustment is required once a day, which affects production efficiency. Therefore, a signal loss prevention device for transmission rod assembly is proposed for double-chamber kilns.
