Description

High-temperature-resistant flexible coke grid sealing device

Technical Field

The utility model relates to the technical field of mechanical part sealing, in particular to a coke oven coke grid sealing device.

Background

For a long time, coke oven production is often accompanied with the phenomena of heavy smoke, heavy fire and the like, the environment is greatly improved after a series of dust removal modification (such as coke discharging dust removal, coal adding dust removal and coke pushing dust removal) is carried out on the coke oven process section, but a large amount of unorganized smoke is still diffused. For example, due to poor rigid contact sealing at the joint of the coke guide and the door frame of the coke oven, and the coke discharging and dust removing suction force cannot reach the bottom of the coke guide, the hot buoyancy force drives the coke powder to escape from the gap at the joint of the coke guide and the door frame of the coke oven during the coke pushing process. In addition, because a large amount of heat is generated on the coke side in the coke pushing process, the residual tar residues on the oven door frame can not be burnt completely under the condition of high temperature and meet air (gushing from a gap at the joint of a coke guide grid of the coke guide car and the oven door frame of the coke oven) to generate a large amount of smoke. Therefore, attempts have been made to improve the rigid contact seal at the junction of the coke guide grate and the oven door frame, for example, by changing the rigid contact seal to a flexible contact, i.e., by replacing the rigid seal with a flexible seal. However, due to the characteristics of high temperature, high impact and frequent action of the coke grid environment, flexible sealing devices on the market at present cannot adapt to the high-temperature coke grid environment, and the unorganized smoke dissipation of the coke grid of the coke oven is not improved all the time.

Disclosure of Invention

The utility model provides a flexible burnt bars sealing device of high temperature resistant, it can satisfy the high temperature of burnt bars environment, high impact, the frequent characteristics of action, can play the fine sealing action of coke guide bars and furnace door frame junction again to the coke guide to the problem that the inorganization smoke and dust loss of above-mentioned coke oven burnt bars has not been improved always has been solved.

In order to solve the above problem, the utility model discloses a technical scheme is:

the coke grid fire-resisting device comprises a base which is vertically arranged on the side face of a coke grid and the cross section of the base is bent, a flexible high-temperature-resisting fire-resisting tube is vertically arranged on the base relative to the other bending plane of the coke grid through a clamping flat steel and a locking bolt which penetrates through the clamping flat steel, the high-temperature-resisting fire-resisting tube comprises a round tube and a flat clamping position which extends out of one side of the round tube, the flat clamping position is located between the clamping flat steel and the base, and woven asbestos is filled in the round tube.

In the above technical solution, a more specific technical solution may also be: the base is formed by back welding two angle steels.

Furthermore, the locking bolt comprises a screw and an adjusting compression nut matched with the screw.

Since the technical scheme is used, compared with the prior art, the utility model following beneficial effect has:

1. the utility model discloses a change the rigid contact sealing device that current coke guide coke grid and coke oven door frame combine the department into the adoption and fill the flexible sealing device that has the high temperature resistant fire-retardant pipe that weaves asbestos, this flexible sealing device can satisfy the high temperature of coke grid environment, high impact, the frequent characteristics of action, can play again to the fine sealed effect of coke guide coke grid and oven door frame combination department to the problem that the inorganization smoke and dust loss of having solved above-mentioned coke oven coke grid has not been improved always.

2. The utility model discloses a flexible sealing device becomes the rigid seal at the activity position of burnt bars side and burnt bars afterbody flexible, effectively improves the leakproofness to isolated flue gas loss, reduced the coke oven smoking phenomenon of putting out a fire.

3. The utility model discloses because the leakproofness is good to effectual reduction outside air gushes into the space that coke grid and coke oven column formed from the gap of coke guide coke grid and coke oven door frame junction from the coke guide in, makes on the oven door frame residual tar sediment can't burn, thereby reduces to emit the big fire phenomenon.

4. The utility model discloses a flexible seal makes burnt bars and coke oven column form vertical passageway, and steam rises in addition, forms ascending suction in the passageway, and further in leading-in out burnt dust excluding hood with the flue gas, reach good dust removal effect.

5. The utility model discloses owing to adopt and to have the flexible sealing device who weaves asbestos resistant high temperature fire-resistant pipe of hindering and make to inside packing to broken through high temperature, high impact, the frequent environmental factor of action, realized the good sealed effect under high temperature environment, have the characteristics that shock resistance is strong, anti fatigue ability is strong simultaneously.

6. The utility model discloses simple structure facilitates change, the maintenance work of equipment, and it has good gain effect to the unorganized diffusion improvement, has reduced paying out of dust removal cost simultaneously.

7. The utility model discloses reduced the condition that the operation personnel expose in going out burnt adverse circumstances, reduced the contact time with dust, smoke and dust, made operation personnel's safety guarantee and occupational health guarantee all effectively promote.
