Mechanical arm decoking device for coke oven locomotive and control method

Abstract

The invention discloses a mechanical arm coke cleaning device for a coke oven locomotive and a control method, and the action composition comprises the following steps: S1, blowing and scraping coke into a hearth, and blowing a large amount of coke and powder into a furnace (a scraper acts from back to front); s2, perfroming secondary cleaning in the hearth (a scraper is arranged from front to back); s3, cleaning the coke plate outside the furnace mouth (from top to bottom); and S4, folding and retracting to complete the cleaning work of the furnace bottom and the coke dripping plate. Integrated control is carried out through scraper switching, inclined retraction and other actions, the double scraping and sweeping knives are fast and easy to replace, the sweeping mechanical arm freely rotates and is stored in the main mechanical arm after being in place, space is saved, the structure is simple, and the main mechanical arm is completely hidden below a coke pusher furnace front platform after being retracted in place along a guide rail; and the work of mechanisms such as a coke pushing rod and a door taking machine is not influenced. According to the invention, automatic and rapid coke cleaning is realized through control of a hydraulic transmission system, manual coke cleaning work in front of a furnace is completely replaced, and full-load coke pushing production and automatic coke oven operation are guaranteed.

Description

technical field [0001] The invention relates to the technical field of coke oven locomotive auxiliary equipment, in particular to a coke cleaning device and a control method for a coke oven locomotive with a mechanical arm. Background technique [0002] At present, the country's environmental protection access standards for the iron and steel industry are increasing year by year, and labor costs are increasing day by day. Intelligent and unmanned production is an inevitable choice for the coking industry to get out of the predicament. Especially when the manufacturing industry as a whole is at a low ebb, production costs and efficiency are related to the survival of enterprises. It is particularly urgent for coking production to realize efficient and intelligent coke pushing operations and reduce labor productivity.

AI Technical Summary

Problems solved by technology

[0003] In the current coke oven process on the market, in order to prevent the overflow and leakage of toxic and harmful gases in the carbonization chamber, not only the smoke will affect the environment, but also the quality of coke. It is necessary to maintain a good seal between the furnace door and the furnace frame. Therefore, every After opening the furnace door for the first time, remove tar, graphite and other adherents on the furnace door to prevent the sealing performance from decreasing

As the coke oven door and frame are affected by various factors, the accumulation of tar and graphite is relatively fast, and the frequency of cleaning needs to be increased

The coke oven locomotives are all unit automatic, with manual supervision and operation. The operations in front of the furnace are all manual operations. The working environment is harsh, the labor intensity of the workers is high, the operation is repeated for a long time, the operation accuracy is poor, operation accidents are prone to occur, the labor productivity is low, and the number of personnel is occupied. many
