Air leakage-free fixed slideway device used for sintering

Abstract

The invention discloses an air leakage-free fixed slideway device used for sintering. The air leakage-free fixed slideway device used for sintering comprises a slideway main plate made of high-temperature carbon steel materials. Slideway connectors are arranged at the two ends of the slideway main plate and are used for connecting adjacent fixed slideways. Each slideway connector is in an invertedL-shaped structure. An oil outlet is formed in the middle of the slideway main plate. Oil grooves are formed in the two sides of the oil outlet. A fan-shaped groove is formed in the end, away from the oil outlet, of each oil groove. The depth of the tail end of each fan-shaped groove is decreased gradually till the tail end of the fan-shaped groove is flush with the slideway main plate, so that lubricating oil is evenly spread. The two ends of the slideway main plate are respectively provided with two sets of graphite columns. According to the air leakage-free fixed slideway device used for sintering, lubricating oil can be evenly distributed on the surface of the slideway main plate through the oil grooves and the fan-shaped grooves, and graphite powder generated by the graphite columnscan achieve an auxiliary lubricating effect, so that the lubricating efficiency is greatly improved; and in addition, the L-shaped slideway connectors can achieve good connection and air leakage prevention effects, so that normal operation of equipment is ensured.

Description

technical field [0001] The invention relates to the technical field of fixed slideways, in particular to a non-leakage fixed slideway device for sintering. Background technique [0002] In the sintering process of iron ore, the sintering machine is the main equipment, and the lower part of the sintering machine is connected with the fixed slideway, and its lubricity and air leakage rate are the main inspection parameters. When the air leakage rate at the slideway connection is too high, the hot air utilization rate is low, which affects the sintering quality. In addition, the sintering trolley is heavy and requires strong power to pull it. The lubricity of the contact surface is an important parameter affecting the movement of the trolley. The lubricity is poor, the friction between the trolley and the slideway is large, the wear is serious, and it also reduces Improve the mobility of the trolley. At present, the length of the commonly used fixed slideways is 1m, and sever...

Problems solved by technology

When the air leakage rate at the slideway connection is too high, the hot air utilization rate is low, which affects the sintering quality

In addition, the sintering trolley is heavy and requires strong power to pull it. The lubricity of the contact surface is an important parameter affecting the movement of the trolley. The lubricity is poor, the friction between the trolley and the slideway is large, the wear is serious, and it also reduces Mobility of the trolley

At present, the length of the commonly used fixed slideway is 1m. The whole sintering system needs to lay several slideways. There are many gaps between the slideways, and air leakage is inevitable.

In addition, most of the fixed slides are lubricated with lubricating oil. Generally, each slide has two oil outlets. The entire operation process consumes a lot of oil and costs a lot.
