Abstract
The utility model provides a stopper lid formula hole of dialling a fire, including outer barrel and sealed lid, sealed lid is arranged in outer barrel top, and contact department is equipped with the sealing washer, still includes fire-resistant plunger, and fire-resistant plunger is the cylinder structure, and the top is equipped with the flange, and the inner wall top of outer barrel is equipped with the circular bead, fire-resistant plunger top flange with circular bead overlap joint configuration. The utility model provides a structure of old-fashioned fire poking hole integration appear easily that refractory material easily drops and damages, equips that the life-span is short, the fire, leak out, warp the scheduling problem, ensured the security and the reliability of device.
Description
Technical Field
The utility model belongs to the technical field of dial the fire hole, especially, relate to a plug cover formula dials fire hole.
Background
The fire poking hole is a device for checking the combustion condition in the kiln and cleaning and maintaining the refractory structure in the kiln chamber, is closed in the production state and is opened in the maintenance and overhaul state. The fire-poking hole needs to have double functions of fire resistance, heat insulation and sealing. In the existing design of the fire poking hole (see fig. 1), a cover plate is integrally poured with a fireproof material for heat insulation and fire prevention, the fireproof material integrally poured on the cover plate is easy to fall off and damage due to frequent opening and closing of the cover plate in the using process, so that the heat insulation and fire prevention effects are lost, a sealing cover is generally a steel or alloy steel metal part and deforms due to heat radiation inside a hearth to cause sealing failure, if the fire poking hole is not sealed tightly, a small amount of hot smoke is leaked out through a gap of the sealing cover to cause the sealing cover to be not sealed tightly, local fire is emitted, and the situation and the danger are serious.
Disclosure of Invention
The utility model aims to solve the technical problem that to the problem that above-mentioned exists, provide a stopper lid formula hole of dialling a fire, will dial the structure decomposition in hole and be "fire-resistant plunger" and "sealed lid" two parts, ensured the security and the reliability of device.
The utility model provides a technical scheme that above-mentioned technical problem adopted is: the utility model provides a plug cover formula hole of dialling a fire, includes outer barrel and sealed lid, sealed lid is arranged in outer barrel top, contact department are equipped with the sealing washer, its characterized in that still includes fire-resistant plunger, fire-resistant plunger is the cylinder structure, and the top is equipped with the flange, the inner wall top of outer barrel is equipped with the circular bead, fire-resistant plunger top flange with circular bead overlap joint configuration, there is the interval between fire-resistant plunger top and the sealed lid bottom.
According to the scheme, the lap joint of the flange at the top end of the fire-resistant plunger and the shoulder is provided with the fire-resistant pad.
According to the scheme, the center of the top of the fire-resistant plunger is provided with the shackle.
According to the scheme, the diameter of the fire-resistant plunger is matched with the inner diameter of the outer cylinder.
The utility model has the advantages that: the utility model provides a gag formula hole of dialling a fire, the structure that will dial a fire hole decomposes into "fire-resistant plunger" and "sealed lid" two parts, and fire-resistant plunger is installed in a hole section of thick bamboo, is exclusively used in the flame and the high temperature heat transfer that block, and sealed lid is installed at a hole section of thick bamboo end for seal a hole section of thick bamboo and block that hot flue gas flows from a hole section of thick bamboo, realize fire-resistant thermal-insulated function, sealed lid is exclusively used in and realizes sealed function.

Fig. 2 is a schematic structural diagram of an embodiment of the present invention.
Wherein: 1-outer cylinder, 2-sealing ring, 3-sealing cover, 4-fire-resistant plunger, 5-plunger shackle and 6-fire-resistant pad
Detailed Description
For a better understanding of the present invention, the following description is given in conjunction with the accompanying drawings and examples.
As shown in fig. 2, the plug cap type fire poking hole comprises an outer cylinder body 1 and a sealing cover 3, wherein the sealing cover is arranged at the top of the outer cylinder body, and a sealing ring 2 is arranged at the contact position to realize complete sealing and ensure no leakage of smoke and heat flow. Still include fire-resistant plunger 4, fire-resistant plunger is the cylinder structure, and the top is equipped with the flange, and the inner wall top of outer barrel is equipped with the circular bead, and fire-resistant plunger top flange and circular bead overlap joint configuration have the interval between fire-resistant plunger top and the sealing cover bottom.
The sealing cover is not provided with a refractory material, and an independent refractory plunger is used for isolating the influence of heat and flame on the sealing cover, so that the sealing cover is ensured not to be heated and deformed under the normal working condition. The thickness of the refractory material layer is greatly increased by the refractory plunger, and the heat insulation effect is higher than that of an old-fashioned fire poking hole cover plate. And because the structure of the plug cover separating type is adopted, if the fireproof plunger piston is damaged, the fireproof plunger piston can be independently replaced, and the maintenance cost is reduced.
The lap joint department of fire-resistant plunger top flange and circular bead is equipped with fire-resistant pad 6, and the fire-resistant pad is flexible, prevents that there is flame to emerge in the gap between fire-resistant plunger and the hole section of thick bamboo to prevent that fire-resistant plunger and hole section of thick bamboo from taking place to bond.
The center of the top of the fire-resistant plunger is provided with a shackle 5, so that the fire-resistant plunger can be conveniently taken out and plugged in during operation.
The diameter of the fire-resistant plunger is matched with the inner diameter of the outer cylinder, a certain gap is reserved, flame and radiant heat in the kiln can be isolated, and the fire-resistant plunger is not bonded with the cylinder.
