Coke discharge chute with wear-resisting plate capable of being quickly replaced and quick replacement method of wear-resisting plate

Abstract

The invention provides a coke discharging chute with a wear-resisting plate capable of being rapidly replaced and a rapid replacing method of the wear-resisting plate. The coke discharging chute comprises a double-fork chute which is composed of a first chute and a second chute which are communicated with a coke discharging main pipeline; a coke discharging turning plate which is arranged on the double-fork chute and can be turned over bidirectionally to seal one of the first chute and the second chute, wherein dry quenching coke is discharged through the other one of the first chute and the second chute; manholes which are respectively formed in the first chute and the second chute; the wear-resisting plate which is connected to the pipe walls of the first chute and the second chute; and a fastening assembly which is used for connecting the wear-resisting plate to the first chute and the second chute. According to the coke discharging chute with the wear-resisting plate capable of being rapidly replaced and the rapid replacement method of the wear-resisting plate, when the wear-resisting plate of the coke discharging chute is worn, the wear-resisting plate can be rapidly replaced while normal operation of dry quenching production is ensured, the maintenance and replacement risks are effectively reduced, and the normal operation of the dry quenching production is not influenced.

Description

technical field [0001] The invention belongs to the technical field of dry quenching coke discharge equipment, and in particular relates to a coke discharge chute with a rapidly replaceable wear plate and a quick replacement method for the wear plate. Background technique [0002] CDQ technology is a coke quenching method that uses inert gas to cool red coke to produce coke. It is widely used in metallurgy because of its good performance in saving energy, improving coke quality, absorbing red coke heat and protecting the environment. and other fields. [0003] The coke discharge chute is a pipe through which the material is discharged after CDQ cooling and cooling. Usually, in order to improve the wear resistance of the coke discharge chute tube wall, a cast stone plate is pasted on the coke discharge chute wear plate to prolong the coke discharge chute tube wall. service life. However, due to the intermittent feeding of coke and the influence of the feeding angle of the c...

AI Technical Summary

Problems solved by technology

However, due to the intermittent feeding of coke and the influence of the feeding angle of the coke, the local impact and wear of the coke discharge chute tube wall is serious, causing the cast stone plate to fall off, the wear-resistant plate of the coke discharge chute to be worn out, and sprinkling of materials occurs, resulting in unsatisfactory dust removal effect , resulting in CDQ circulating gas overflowing with coke, dust, and coke powder, and gathering in the basement of the discharge device, which can easily cause the risk of personnel poisoning and suffocation

In the prior art, in order to solve the above-mentioned problems, the method of reversing the coking discharge flap, opening the manhole, and the staff entering the interior of the coking discharge chute to repair the worn part of the coking discharge chute tube wall is usually adopted, but this maintenance method repairs Long time, high repair risk, and affect the normal operation of CDQ production
