Problems solved by technology

[0002] The cutting column is one of the important parts of the calcium carbide furnace. During the production of calcium carbide, the raw materials are evenly distributed around the electrode through the cutting column, and are smelted by the arc heat of the three-phase electrode; It is easy to be damaged by the high-temperature environment when it is used, and it is in contact with the high-temperature material surface; at present, manual replacement is often used when replacing the damaged lower material column. It is very troublesome and wastes time, delays production, and stands on the furnace cover to manually adjust the hoisting position, which has certain safety risks; therefore, it is necessary to find a method that is easy to use, safe and reliable, can quickly replace the feeding column, and improve the efficiency of maintenance work

Embodiment 1

[0015] A method for quickly replacing the blanking column of a calcium carbide furnace. The replacement method includes the following steps:

[0016] Step 1: Install the winch on the trolley with remote control;

[0017] Step 2: Install the trolley walking track above the calcium carbide furnace, and place the trolley on the walking track;

[0018] Step 3: Control the trolley to move to just above the unloading column to be replaced, and the hoist will lower the hook to the unloading column to be replaced;

[0019] Step 4: Hook the blanking column to be replaced, lift the blanking column to be replaced, and transport it to the placement area;

[0020] Step 5: Hang the new unloading column on the hook, move it to the installation position, and install it directly;

[0021] Step 6: After the installation is completed, repeat steps 3, 4, and 5 to replace the next feeding column.

[0022] The invention uses a trolley to drive the hoist to move instead of manually hoisting the discharging colu...

Abstract

The invention relates to a quick replacement method for a calcium carbide furnace discharging column. The replacement method comprises the following steps that a winch is mounted on a trolley with remote control; a trolley travelling track is mounted above a calcium carbide furnace, and the trolley is placed on the travelling track; the trolley is controlled to move to the position over the discharging column to be replaced, and the winch descends a lifting hook to the position of the discharging column to be replaced; the discharging column to be replaced is hooked, and after being lifted, the discharging column to be replaced is conveyed to a placement area; a new discharging column is hung on the lifting hook and moved to the mounting position, and mounting is directly carried out; andafter mounting is completed, the third step, the fourth step and the fifth step are repeated, and replacement of the next discharging column is carried out. In general, the quick replacement method isreasonable in design and has the beneficial effects that use is convenient, safety and reliability are achieved, the discharging column can be quickly replaced, and the overhauling work efficiency isimproved.

Description

Technical field [0001] The invention belongs to the technical field of calcium carbide furnace, and specifically relates to a method for quickly replacing a blanking column of a calcium carbide furnace. Background technique [0002] The blanking column is one of the important parts of the calcium carbide furnace. During the production of calcium carbide, the raw materials are evenly distributed around the electrode through the blanking column, and are smelted by the arc heat of the three-phase electrode; the blanking column in the calcium carbide furnace is under high temperature It is used and has contact with the high temperature material surface, so it is easily damaged by the high temperature environment. At present, when replacing the damaged material column, manual replacement is often used. It is not only necessary to lay the heat insulation board on the high temperature furnace cover, but also requires manual lifting and moving. Very troublesome and time-consuming, delayi...
