Abstract
The invention aims at providing a furnace observing hole which is simple in structure, capable of guaranteeing observing personnel to carry out safe observing, and convenient to use. The furnace observing hole is installed on the side face of a kiln body. The furnace observing hole comprises an observing hole channel which is formed in the wall of the kiln body. The tail end of the observing hole channel is provided with a multi-layer casing pipe. The casing pipe is formed by a pipe casing and three or more layers of thermal insulating glass. Second thermal insulating glass and third thermal insulating glass calculated from inside to outside are combined into a whole. A pipe opening of the multi-layer casing pipe is covered with first thermal insulating glass which is connected with a control rod. In this way, according to the furnace observing hole, a hot gas inside a furnace can be prevented from overflowing without an extra observing hole cover at ordinary times. When observing is needed, direct observing can be carried out. If a large amount of dust is accumulated inside the furnace, only by rotating the control rod, the first thermal insulating glass is opened, and the observing can be carried out. The entire multi-layer casing pipe can be taken out to be subjected to maintenance and cleaning.
Description
Technical field
The present invention relates to a kind of kiln repair apparatus, particularly relate to a kind of kiln observation hole.
Background technology
The security performance of kiln is extremely important.In order to ensure the safe handling of kiln, regularly need to overhaul kiln.And also need when kiln works to check kiln operation conditions.Generally the inspection of kiln is realized by peep hole.Such as prior art Patent number is just relate to a kind of peep hole brick in the utility model patent " peep hole brick " of 200820037580.1, it is characterized in that being provided with flared cavity in brick body (1), this flared cavity is combined by ladder cavity (2) and rectangular enclosure (3) and forms, wherein the bottom surface opening of ladder cavity (2) is positioned on a side of brick body (1), forms the opening of flared cavity.This utility model decreases the connection mortar joint of peep hole place fragment of brick, increases the sight fire visual range of peep hole, decreases the thermal loss of kiln flame-observing hole position.
But peep hole of the prior art has two problems usually, one is owing to being directly through hole, so must cover with heavy handhole cover when not using.Open peep hole all very inconvenient at every turn.Even if another point opens peep hole exactly, the hot gas in kiln still can gush out, and sometimes may damage observer.
Summary of the invention
The object of the present invention is to provide a kind of kiln observation hole, structure is simple, can guarantee that observer observes safely, use also more convenient simultaneously.
In order to realize described object, a kind of kiln observation hole of the present invention, be arranged on kiln body side surface, be included in the peep hole passage that kiln body wall is offered, described peep hole channel end is provided with a multilayer sleeve, described sleeve pipe is by pipe box and at least three layers of heat-protecting glass composition, and wherein calculate second heat-protecting glass and the 3rd heat-protecting glass composition one from inside to outside, described first heat-protecting glass covers the multilayer sleeve mouth of pipe and is connected on control lever.
Preferably, described multilayer sleeve internal diameter is less than peep hole channel internal diameter, and is filled with light material between multilayer sleeve and peep hole passage.Can change owing to heating rear whole kiln wall, kiln wall pressure bad multilayer sleeve can be avoided by light material, also guarantee the heat-proof quality of kiln simultaneously.
Preferably, described multilayer sleeve is cross section is circular.Such structure is convenient to install and take out.
Preferably, described first heat-protecting glass is dark-brown glass.The deformation that such heat radiation that can reduce in kiln brings whole multilayer sleeve.
Preferably, the multilayer sleeve wall between described second and the 3rd heat-protecting glass is provided with heat conduction through hole.Such structure avoids the damage of multilayer sleeve or heat-protecting glass after variations in temperature.
By such setting, the steam leakage that a kind of kiln observation of the present invention hole does not need extra handhole cover just can prevent in kiln at ordinary times.Need can directly observe when observing.If kiln dust deposit in furnace is more, just can observe as long as turn on first heat-protecting glass by rotation control rod.Whole multilayer sleeve also can take out and carry out safeguarding and clearing up.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of place, a kind of kiln observation hole of the present invention kiln.
Fig. 2 is the multilayer sleeve structure schematic diagram in a kind of kiln observation hole of the present invention.
Detailed description of the invention
A kind of kiln observation hole, be arranged on kiln body 1 side, be included in the peep hole passage that kiln body 1 wall is offered, described peep hole channel end is provided with a multilayer sleeve 2, described sleeve pipe is by pipe box and at least three layers of heat-protecting glass composition, wherein calculate second heat-protecting glass 4 and the 3rd heat-protecting glass 5 composition one from inside to outside, described first heat-protecting glass 3 covers multilayer sleeve 2 mouth of pipe and is connected on control lever 6.Described multilayer sleeve 2 internal diameter is less than peep hole channel internal diameter, and is filled with light material between multilayer sleeve 2 and peep hole passage.Described multilayer sleeve 2 for cross section be circular.Described first heat-protecting glass 3 is dark-brown glass.Multilayer sleeve 2 wall between described second heat-protecting glass 4 and the 3rd heat-protecting glass 5 is provided with heat conduction through hole 7.
By such structure, operationally only need directly to be observed by peep hole passage.Multilayer sleeve 2 plays the effect of a protection.In some kiln bodies 1, dust stratification is more, can remove first heat-protecting glass 3 like this observe by rotation control rod 6.
Whole multilayer sleeve 2 also can whole taking-up carry out safeguarding and cleaning.By the present invention, observation and the protection of kiln body 1 can be taken into account, very practical.
Claims (5)
