Automatic ash unloading control system of circular cooling ash unloading trolley

Abstract

The invention discloses an automatic ash unloading control system of a circular cooling ash unloading trolley. The automatic ash unloading control system comprises proximity switches which are separately mounted on trolley rails of all ash unloading points, wherein proximity switch boards matched with the proximity switches are mounted on the circular cooling ash unloading trolley, all proximity switches are simultaneously in signal connection with a PLC controller, the PLC controller is also simultaneously in signal connection with a driving motor of the circular cooling ash unloading trolley, a circular cooling ash unloading valve of the circular cooling ash unloading trolley and a host computer, and the host computer is in signal connection with an alarm. The automatic ash unloading control system has the advantages that the timely ash unloading of the circular cooling ash unloading trolley can be automatically controlled, the occurring of production quality events caused by non-timely unloading is avoided, and the stability of the production process and the stability of furnace burden quality are improved; and at the same time, the labor intensity of operators is greatly reduced, the running condition of the circular cooling ash unloading trolley can be monitored in real time, and the operators can timely discover the abnormal condition of the trolley.

Description

technical field [0001] The invention relates to the technical field of ring-cooled ash unloading in iron and steel metallurgical charge plants such as sintering plants and pelletizing plants, and in particular to an automatic ash-unloading control system for a ring-cooled ash unloading trolley. Background technique [0002] The ring cooling ash unloading system of iron and steel metallurgical charge factories such as sintering plants and pelletizing plants is the key process control in the ring cooling process of sintering and pelletizing furnace materials. Its main working principle is: the bulk material blown out by the blower in the ring cooling process and The dust is discharged to the ring-cooled ash unloading trolley through the double-layer ash discharge valve, and then the ring-cooled ash unloading trolley is transported along the trolley track to the ash unloading point for ash discharge. At present, the ash unloading process of the ring-cooled ash unloading trolley...

AI Technical Summary

Problems solved by technology

The above-mentioned manual ash unloading operation method has the following disadvantages: the ring-cooled ash unloading trolley cannot unload the ash in time, and it is very easy to cause production quality accidents due to unloading in time, the stability of the production process and the quality of the charge are poor, and the labor intensity of the workers high
