Technical Field

The invention belongs to the technical field of calcium carbide furnaces, and particularly relates to a method for quickly replacing a discharging column of a calcium carbide furnace.

Background

The blanking column is one of important components of the calcium carbide furnace, and during the production of the calcium carbide, raw materials are uniformly distributed around the electrodes through the blanking column and are smelted by means of arc heat of the three-phase electrodes; the in-furnace blanking column of the calcium carbide furnace is used at high temperature, is in contact with a high-temperature charge level and is easily damaged by a high-temperature environment; at present, the damaged blanking column is replaced manually, a heat insulation plate needs to be laid on a high-temperature furnace cover, manual hoisting movement is needed, the process is very troublesome, time is wasted, production is delayed, and a certain safety risk exists because the hoisting position is manually adjusted when the furnace cover is stood on; therefore, a method which is convenient to use, safe and reliable, can rapidly replace the blanking column and improves the maintenance work efficiency is required to be found.

Disclosure of Invention

The invention aims to provide a method which is convenient to use, safe and reliable, can quickly replace a blanking column and improves the maintenance work efficiency.

The purpose of the invention is realized as follows: a method for quickly replacing a discharging column of a calcium carbide furnace comprises the following steps:

the method comprises the following steps: installing a winch on a trolley with remote control;

step two: installing a trolley travelling rail above the calcium carbide furnace, and placing the trolley on the travelling rail;

step three: controlling the trolley to move to the position right above the blanking column to be replaced, and lowering the lifting hook to the position of the blanking column to be replaced by the winch;

step four: hooking the blanking column to be replaced, lifting the blanking column to be replaced, and transporting the blanking column to a placing area;

step five: hanging the new blanking column on a lifting hook, moving to an installation position, and directly installing;

step six: and after the installation is finished, repeating the third, fourth and fifth steps to replace the next blanking column.

The trolley is an electric control trolley, and wheels of the trolley have a self-locking function.

The invention has the beneficial effects that: according to the invention, the trolley is used for driving the winch to move to replace manual hoisting of the blanking column, so that the number of replacing personnel is reduced, the labor intensity of the replacing personnel is reduced, the replacing personnel can remotely control to replace the blanking column, and the work safety risk of the replacing personnel is greatly reduced; the replacement procedure is simplified, so that the replacement of the blanking column is more rapid, the downtime is saved, the heat loss is reduced to the maximum extent, and the shutdown loss is reduced to the minimum; in general, the blanking column has the advantages of reasonable design, convenience in use, safety, reliability, capability of quickly replacing the blanking column and improvement of the maintenance work efficiency.
