Description

Rotary sleeve for main arm of calcium carbide discharging machine

Technical Field

The utility model relates to a carbide equipment field of coming out of stove, concretely relates to a rotatory sleeve that is used for carbide to go out of stove on quick-witted main beam arm.

Background

The industrial calcium carbide furnace mostly adopts manual work for discharging operation, and usually a plurality of people lift up the long end effector to perform operations such as poking, opening and blocking the eyes. For the manually operated calcium carbide furnace, the production is often influenced by the difficulty and even accidents. Because the calcium carbide furnace has higher temperature and high current, the manual operation intensity is high and the danger is very high. Therefore, in the process of discharging operation, calcium carbide production enterprises on the prior scale use automatic discharging machines to operate and complete a series of work such as burning-through, hole poking, hole plugging, furnace hole maintenance and the like, so that calcium carbide furnace discharging machine equipment is particularly important in calcium carbide production at present, and the improvement of the mechanization degree of a discharging post and the improvement of the working environment of a furnace front work are great trends in calcium carbide production, and are also related to the targets of safe production and clean production in the calcium carbide production industry. The calcium carbide furnace discharging process generally comprises three main processes of opening a furnace eye, guiding outflow, blocking the furnace eye and the like, wherein different end effectors are used in each process. When the furnace eye opening process is executed, the adopted end effector is a conductive graphite rod. The graphite rod is penetrated to the opening part of the furnace mouth, high temperature is generated through electric arc discharge, and the opening part of the furnace mouth is opened under the action of high temperature and pressure. Then, a guiding and flowing-out step is performed in which the end effector is inserted into the furnace to lead out the molten material in the furnace, and the molten material is introduced into the ladle through the furnace throat. In the furnace eye blocking process, cylindrical clay is plugged into the furnace eye through the tail end of the actuator, so that substances in the furnace eye are cooled and solidified, and the furnace eye blocking process is completed. Accomplish above process and mainly lean on control carbide stove out of furnace machine main boom to realize, stove out of furnace machine main boom is the important part of stove out of furnace machine, install the swivel sleeve on the stove out of furnace machine main boom usually, the swivel sleeve is two when installing on stove out of furnace machine main boom and is fixed by the assembly of intermediate junction pole, be equipped with wear-resisting copper sheathing between two intermediate junction poles, it is fixed through 6 high-strength countersunk head bolts by the terminal stopping backing plate of intermediate junction pole after the assembly targets in place, it is reliable when guaranteeing the intermediate junction pole to rotate, firm, do not fall off, nevertheless discover in the use because the main boom is rotatory to drive the intermediate junction pole rotatory, lead to stopping backing plate fixing bolt not hard up to withdraw from, shearing fracture after the atress, thereby it restricts the normal use of carbide stove out of furnace machine to lead to frequent trouble of.
