Description

Technical Field

[0001] The utility model relates to the technical field of sintering equipment, in particular to an integral material blocking block for a tail material guide chute of a sintering machine. Background Art

[0002] The working condition of the sintering single-roller guide trough is poor. The guide trough with a sintering ore drop of 6m is quickly degraded by the impact of high-temperature ore. The guide trough stopper frequently falls off due to impact during production, resulting in equipment accidents. The stopper block and foundation are deformed by high temperature, making it difficult to disassemble and assemble. The short life of the stopper block restricts the operating rate and maintenance cycle of the sintering machine.

[0003] The existing guide chute has a structure in which the blocking blocks are installed at the front end of the trough. The front end of the guide chute has a foundation, and the blocking blocks are fixed to the foundation with screws. There are many blocking blocks, but they have low wear resistance and are easily fallen off by the impact of materials. Every two months, the machine needs to be shut down for maintenance and replacement of a large number of wear-resistant blocks, resulting in high spare parts consumption costs. Falling blocking blocks can cause a chain reaction of single-roller gear shaft breakage accidents. Emergency repairs are difficult because water must be flushed to lower the temperature before entering the single-roller crusher to lift out the fallen blocking blocks. The ambient temperature is high, the labor intensity of emergency repairs is high, and the safety risks are high. Each time the guide chute is repaired, the sintering machine needs to be shut down for about 30 hours. The spare parts cost is high, which seriously restricts the operating rate and maintenance cycle of the sintering machine. Utility Model Content
