Abstract
A seal device for the seal cover and the coal cake of an oven door of a coke oven side-mounting coal truck relates to the seal device of the oven door of a vertical tamping coke oven side-mounting coal truck. The structure of the seal device is that an air compressor and a gas bag are arranged on the side-mounting coal truck body; the gas bag and a fixed gas pipe which is arranged on the seal cover are connected through a gas path system; and a plurality of vent holes are formed on the wall of the fixed gas pipe. In the utility model, the seal structure adopting a compressed gas curtain is additionally arranged on the seal device of the prior oven door, so that the gap between the coal cake and the seal cover is completely enclosed, raw coke oven gas is prevented from escaping, the seal problem between the coal cake and the seal cover is solved, the environment-friendly performance of the coke oven is effectively enhanced, and the working environment of operation and maintenance workers is improved.
Description
Technical field
The utility model relates to the tightness system of vertical tamping coke oven side coal car fire door, the particularly tightness system between coke oven side coal car oven door sealing cover and the briquette.
Background technology
At present, the furnace door sealing device of vertical tamping coke oven side coal car mainly is made up of seal closure 1, roller apparatus 2, cylinder apparatus 3, cylinder bracket 5, track support 6 etc. as depicted in figs. 1 and 2.Cylinder bracket 5 and track support 6 are fixed on the side plate support 9 of side coal car.The flexible soft seal 4 of the peripheral band of seal closure 1.When furnace door sealing device is worked, drive the roller apparatus 2 that is fixed on the seal closure 1 by cylinder apparatus 3 and on track support 6, advance, elastic soft sealing 4 is withstood on the furnace stay 8, thereby the raw gas that produces will coaling the time is sealed in furnace stay 8 with in the interior coking chamber.Because the rectangular indentation that the mid-way of seal closure 1 can make briquette 10 normally pass through in addition, therefore, also have a large amount of raw gas to overflow from the space between briquette 10 and the seal closure 1, can not really between briquette 10, seal closure 1, coke oven furnace stay 8, coking furnace shaft front wall 7, all form seal cavity, the raw gas that overflows from space between briquette 10 and the seal closure 1, the severe contamination Working environment influences the healthy of operator.Sealing problem between still unresolved briquette 10 of prior art and the seal closure 1.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes prior art, and the tightness system of a kind of coke oven side coal car oven door sealing cover and briquette is provided, and solves the sealing problem between vertical tamping coke oven side coal car oven door sealing cover and the briquette.
The utility model is achieved through the following technical solutions:
The tightness system of a kind of coke oven side coal car oven door sealing cover and briquette, it is characterized in that: the structure of described tightness system is: air compressor machine and gas bag are arranged on the side coal car car body, with gas bag and the fixed air pipe coupling that is arranged on the seal closure, fixedly offer the exhaust hole of some quantity by air-channel system on the tube wall of tracheae.
Described air-channel system connects reducing valve, filter tap, ball valve by steel pipe, again with hose connection, and flexible pipe and fixed air pipe coupling.
The utility model compared with prior art has the following advantages and beneficial effect:
The utility model is applied in the furnace door sealing device of side coal car, can not influence under the prerequisite of carrying out working properly of coalingging, and adopts the pressurized gas curtain with the space complete closed between briquette and the seal closure.Really form complete sealed space, stop raw gas to overflow, improved the environmental-protecting performance of coke oven effectively, improved Operation and Maintenance personnel's Working environment at briquette, seal closure, coke oven furnace stay, coking furnace shaft front between the walls.

Embodiment
The tightness system of a kind of coke oven side coal car oven door sealing cover and briquette, adopt air compressor machine 14 and gas bag 15 that pressurized air is provided, air compressor machine 14 and gas bag 15 are arranged on the side coal car car body, by air-channel system gas bag 15 is connected with fixedly tracheae 11 on being arranged on seal closure 1, fixedly offers the exhaust hole of some quantity on the tube wall of tracheae 11.
Described air-channel system connects reducing valve 17, filter tap 18, ball valve 19 by steel pipe 16, is connected with flexible pipe 20 again, and flexible pipe 20 is connected with fixing tracheae 11.By regulating reducing valve 17 and ball valve 19, can make the air pressure of pressurized gas and flow reach perfect condition.
When coal charger began to coaling work, furnace door sealing device drove seal closure 1 by cylinder apparatus 3 and advances, and the elastic soft sealing on the seal closure 4 is withstood on the furnace stay 8.When briquette 10 arrives wall 7 positions, coking furnace shaft front, the tightness system of oven door sealing cover of the present utility model and briquette is started working, pressurized air arrives the fixedly tracheae 11 of furnace door sealing device by steel pipe 16 and flexible pipe 20, owing to fixedly evenly be furnished with exhaust hole on the tracheae, pressurized air sees through spilehole and blows out, and forms pressurized gas curtain 12 between briquette.Enter in the whole process of coking chamber 13 at briquette 10, pressurized gas curtain 12 seals the space between briquette 10 and the seal closure 1 fully.
