Abstract
The utility model relates to a box-like coke oven sealing roof cover, particularly a mobile type sealing roof cover suitable for the box-like coke oven. The sealing roof cover is composed of a plurality of small inter-dependent roof covers. The small roof cover comprises a bearing beam and a special-shaped refractory brick arranged in the lower part of the bearing beam. The utility model has the advantages of simple structure, low cost and convenient operation, which is suitable for the improved coke ovens.
Description
The utility model relates to a kind of pit kiln top pressure closure, especially is suitable for the movable top pressure closure that coking chamber uses.
Existing box closed type pit kiln, its top pressure closure has two classes usually, one class is fixed airtight top cover, as Chinese patent CN87212113U disclosed a kind of " pit kiln ", it pushes up by the chimney arch of being built by laying bricks or stones by refractory materials that the two side wall supports, constitute the pit kiln of a sealing, the shortcoming of this type of furnace is charging, it is extremely inconvenient to discharge of the coke, influence workman's operation, simultaneously in coking, in the different operations such as quenching,, easily make furnace roof produce the crack because of expanding with heat and contract with cold or subside because the temperature difference is bigger, at above-mentioned deficiency, invented another kind of movable pit kiln top pressure closure.As Chinese patent 90207844.5 disclosed " pit kiln bell ", this bell is by " at least two above inverted T shape back timbers constitute a spatial grid structure lid, and the lid lower end hangs with heterotypic fire brick.Constitute the thermal insulation layer of a sealing, the two ends of lid be provided with the sidewall of the furnace body wall on the scroll wheel that is complementary of the track that is provided with, thereby constitute an independently tegillum, combined movable bell of some tegillum one-tenth capable of being combined." shortcoming of this bell is complex structure, the cost height, operation inconvenience must have supporting dedicated track and dolly.
The purpose of this utility model is at above-mentioned deficiency, and a kind of simple in structure, coking chamber top pressure closure that cost is low, easy and simple to handle is provided.
The utility model coking chamber top pressure closure is made up of some separate little top covers that are arranged on the wall of box coke oven two side.This little top cover is to be had the bearing beam of T-shape groove and protruded the cross section that the limit embeds in this T type groove on several by a bottom to constitute for the heterotypic fire brick of " worker " font.
In order to reduce cost, reduce the usage quantity of little top cover, can keep at a certain distance away between each little top cover, several rectangular firebricks are set therebetween, these rectangular firebricks protrude the limit support down by " worker " font refractory brick of little top cover bottom, and the two constitutes the thermal insulation layer of a sealing jointly.
The utility model has the advantages that simple in structure, cost is low, good sealing effect, easy to operate.
Below in conjunction with accompanying drawing the utility model being made detail describes.
Fig. 1 is the bearing beam of the little top cover of the utility model.
Fig. 2 is square (side) shape refractory brick
Fig. 3 is that the cross section is I-shaped refractory brick
Fig. 4 is little top cover
Fig. 5 is the utility model user mode synoptic diagram
With reference to accompanying drawing, little top cover of the present utility model is made of bearing beam 1 and " worker " font refractory brick 2, in bearing beam 1 bottom one T-slot 5 is arranged, and the protrusion limit 3 of going up of refractory brick 2 is complementary with T-slot 5, and embeds in this groove, constitutes the thermal insulation layer of a sealing.Some little top covers are arranged in order, and promptly form a combined labyrinth and carbon gland top cover.
A preferred embodiment of the present utility model is provided by Fig. 5.In this embodiment, keep at a certain distance away between the little top cover, the following protrusion limit 4 by two I-shaped refractory brick 2 in little top cover bottom is provided with row square (side) type refractory brick 6, thereby constitute the thermal insulation layer of a sealing, simultaneously, save the consumption of little top cover greatly, reduced cost.
Claims (2)
1, a kind of coking chamber top pressure closure, form by some separate little top covers that are arranged on this coke oven two side wall, it is characterized in that little top cover is that to be had the bearing beam (1) of T-slot (5) and protruded the cross section that limit (3) embeds in this T type groove on several by a bottom be that I-shaped heterotypic fire brick (2) constitutes.
2, coking chamber top pressure closure according to claim 1, it is characterized in that having certain distance at interval between each independent little top cover, be provided with rectangular firebrick (6) therebetween, this rectangular firebrick (6) is supported by the following protrusion limit (4) of the I-shaped refractory brick (2) of little top cover bottom, and the two (2,6) constitute the thermal insulation layer of a sealing jointly.
