Description

A kind of coke oven dust movement docking ball seal device
Technical field
The utility model is related to coke oven dust technical field, more particularly to a kind of coke oven dust movement docking ball seal dress Put.
Background technology
Discharge of the coke in coke oven, coaling, pusher side fire door position is equipped with dust trapping device, what these dust trapping devices had sets (such as dedusting air-suction cover) is put on mobile coke vehicle, and what is had is arranged on fixed coke oven machine side or coke side.Coke oven is in difference Fire door when coalingging or the discharging of the coke, it is above-mentioned that dust trapping device is by mobile coke vehicle and is arranged on coke oven affiliated facility Docking facilities be connected.After connection, coke oven smoke is sucked up to dedusting earth station nearby by pipeline and carried out after purified treatment Qualified discharge.
At present, disclosure satisfy that the device of coke oven dust flue gas movement docking mainly has docking port valve gear, belt sealing pair Connection device, water-stop docking facilities etc..After apparatus above puts into operation, there is following defect:
1) docking port valve gear seals docking facilities with belt:Interface valve gear in coke oven dust is docked with belt sealing All there is the continuous sealing face of large area in device, these sealing surfaces are due to the seal form contacted using face, in long-term use During, as flue-gas temperature constantly changes, sealing surface is constantly acted on by powerful external force, is started appearance and is deformed and cause leakage Wind.Especially in the big place of asynchronous region length, total inleakage is huge.So, in dedusting air-breathing, dust removing effects significantly decline Subtract.
2) water-stop docking facilities:Although water-stop docking facilities solve sealing surface leakage problem, but this kind of device is needed New water is constantly supplemented, and sewage can be produced, it is necessary to be additionally carried out processing to the water of pollution.Therefore package unit auxiliary device Huge, operation is complicated;A large amount of sludge that the main bottom of other water-stop docking facilities can be deposited, averagely every 2~3 months just Need to stop production and carry out manual cleaning, because the water surface easily freezes, cold district can not be used in the winter time.
In summary, how to solve the sealing surface of movement butt joint device after long-term use and do not result in moderate finite deformation and leakage Wind phenomenon is to ensure coke oven dust effect, improve the key technique problem of dust arrestment rate.
The content of the invention
