Description

Technical Field

[0002] The dry coke quenching loading device of the ironmaking plant is designed with a distributor. The distributor is suspended in the lower middle position through a crossbeam installed in the hopper. When the coke in the coke tank is put into the dry coke quenching oven, it plays a role in dispersing the coke and dispersing the gravity impact on the gas supply device in the dry coke quenching oven. The distributor has a service life of about 6 months. It will be discarded after being washed and perforated by coke. In order to achieve the function of distributing, it is necessary to suspend the coke loading for repair work. The distributor and its surroundings are exposed to high temperature. Each repair operation needs to suspend the coke loading for cooling before repairing, which takes about 3 hours. The dry coke quenching device normally has only about 1 hour of maintenance time per day, and there is no condition for the maintenance of the distributor. If it is not repaired, it will be impacted by coke, the holes will become larger and larger, and eventually lose its function. If it is replaced, the entire maintenance time will be more than 8 hours, which will cause the production of the dry coke quenching device to be suspended, resulting in greater economic losses.

[0035] For details, please refer to the attached Figure 1 With attached Figure 3 The base 1 is a truncated cone-shaped shell with a hollow shell inside. A scaly protrusion 2 is arranged on the outer wall of the base 1. The scaly protrusion 2 is a tubular structure with its lower end fixed on the base 1. The central axis of the scaly protrusion 2 is coaxially arranged with the central axis of the base 1. A sufficient amount of filler 3 is arranged between the outer peripheral surface of the base 1 and the scaly protrusion 2, so as to increase the thickness of the surface of the base 1.
