Graphite purging device for root of ascending pipe of coke oven machinery

Abstract

The invention discloses a graphite purging device for the root of an ascending pipe of coke oven machinery. The graphite purging device comprises a coke pushing device and a purging system, wherein the coke pushing device comprises a coke pushing head, a coke pushing rod and a coke pushing transmission gear; the purging system comprises an air compressor, an air bag, a gas circuit magnetic valve, a blowing pipeline, a rubber tube assembly, a cable-supporting pulley, a pulley track beam, a rolling wheel, a slide way and a blowing pipeline driving mechanism; the pulley track beam is fixed above the one side of the coke pushing device; the slide way is fixed right above the coke pushing rod of the coke pushing device; the blowing pipeline is placed on the slide way through the rolling wheel; the front part of the blowing pipeline is propped against the coke pushing head; the rubber tube assembly is placed on the cable-supporting pulley and connected with the rear part of the blowing pipeline; one end of a steel wire rope of the blowing pipeline driving mechanism is connected with the tail part of the blowing pipeline, while the other end is connected with a pulling mechanism; and a backstop is installed on the pulling mechanism. The beneficial effects of the graphite purging device are as follows: the device can ensure the operation period of the coke pushing device, effectively remove the graphite which is at the root of the ascending pipe, improve the production stability of the coke oven body and the operation efficiency of the coke oven machinery, avoid smoke and dust from escaping, and protect environment.

Description

technical field [0001] The invention belongs to the technical field of coke oven machinery, and in particular relates to a graphite purging device at the root of an ascending pipe of coke oven machinery equipment. Background technique [0002] In the prior art, the purge pipeline and purge head at the root of the coke oven mechanical equipment riser are fixed on the coke pushing rod and the coke pushing head, and enter and exit the carbonization chamber simultaneously with the coke pushing rod and the coke pushing head. When the coke pushing head advances to the root of the ascending pipe in the carbonization chamber, the solenoid valve of the air circuit is opened through the electrical control signal, and high-pressure air is blown to carry out the graphite purge operation at the root of the ascending pipe. Affected by the operation cycle of the coke pushing machine, the high-pressure air injection time is 20 seconds. The deficiencies of the prior art are: because the hig...

AI Technical Summary

Problems solved by technology

The deficiencies of the prior art are: because the high-pressure air injection time is 20 seconds, which is relatively short, the graphite at the root of the ascending pipe cannot be cleaned, and it is easy to cause graphite to accumulate at the root of the ascending pipe. Excessive accumulation will affect the negative pressure of the furnace body The normal adjustment will cause a lot of smoke and dust to escape and pollute the environment
