[0002] The acetylene cracking furnace is the core key equipment for producing acetylene by partial oxidation of natural gas. The cracking reaction is a rapid reaction under normal pressure and high temperature. The main by-reaction product is char. The char adheres to the inner wall of the reaction chamber of the acetylene cracking furnace and needs to be cleaned regularly.

[0003] At present, due to its fast reaction speed and unavoidable side reactions, the decoking cycle of the acetylene cracking furnace is very short, so the decoking mechanism of the acetylene cracking furnace is frequently operated; at the same time, due to the long overall structure of the decoking mechanism and the large friction resistance, it is easy to cause the components to rub against each other during operation, causing the components to wear quickly, and the impurities generated by the wear accumulate at the joints of the components, further increasing the probability of the operating connecting rod getting stuck during operation.

[0004] In order to solve the above problems, it is urgent to design a cleaning and lubrication mechanism that can lubricate the parts at the connection of the operating link and clean and discharge the impurities generated at the connection of each part, thereby ultimately reducing the probability of the operating link getting stuck during operation.
