Abstract

The utility model discloses a resistant flue gas erodees peephole prefab, form the same prefab of four block shapes of cuboid including the concatenation, prefab concatenation portion is equipped with the channel, and cuboid prefab central authorities after the concatenation have the peephole of loudspeaker form. The utility model divides the peep hole into 4 independent prefabricated parts, thereby reducing the whole impact of heat and improving the impact resistance of the prefabricated parts; the peephole prefabricated parts form a horn-shaped peephole after being combined, so that solid particle impurities such as smoke dust and the like are not easy to accumulate, and the long-time use of the peephole is not influenced; the peephole prefabricated parts are respectively fixed with the furnace body of the kiln, and when one prefabricated part is damaged, the prefabricated part can be disassembled more quickly, so that the maintenance is convenient; the peephole prefabricated member is made of a certain steel fiber material, so that the strength and the heat-resistant temperature of the peephole prefabricated member are improved.

Description

Flue gas erosion resistant peephole prefabricated part

Technical Field

The utility model belongs to the refractory material field, concretely relates to resistant flue gas that thermal expansion is good, convenient maintenance erodees peephole prefab.

Background

When a large-scale kiln is used for firing products, the conditions in the kiln are generally observed through peepholes arranged on the kiln wall. Most of the traditional peepholes are provided with through holes on the brick body, the operation causes the strength reduction of the brick body, and under the condition of extremely high temperature in the furnace, the brick body is easy to damage or crack due to thermal expansion. In addition, most of traditional peepholes are square holes, and impurities such as smoke dust are easily accumulated due to excessive folding angles.

Disclosure of Invention

The purpose of the invention is as follows: an object of the utility model is to provide a resistant flue gas that thermal expansion is good, convenient maintenance erodees peephole prefab to prior art not enough.

The technical scheme is as follows: in order to achieve the above object, the present invention is specifically completed as follows: the utility model provides a resistant flue gas erodees peephole prefab, forms the same prefab of four block shapes of cuboid including the concatenation, prefab concatenation portion is equipped with the channel, and cuboid prefab central authorities after the concatenation have the peephole of loudspeaker form.

The cross section of the channel consists of a rectangle and a right trapezoid, and the width of the rectangle is equal to the upper bottom of the right trapezoid.

And a threaded counter bore is arranged on the surface of the prefabricated part, which is perpendicular to the channel, and a bolt is screwed in the counter bore.

And a nut is fixed at the end part of the bolt outside the counter bore.

And a gasket is additionally arranged between the nut and the prefabricated part.

Wherein the preform contains 3% steel fibres.

Has the advantages that: compared with the prior art, the utility model, there are following advantage:

(1) the peephole is divided into 4 independent prefabricated parts, so that the impact of heat on the whole is reduced, and the impact resistance strength of the prefabricated parts is improved;

(2) the funnel-shaped peephole is formed after the flue gas scouring resistant peephole prefabricated parts are combined, so that solid particle impurities such as smoke dust and the like are not easy to accumulate, and the long-time use of the peephole is not influenced;

(3) the flue gas erosion resistant peephole prefabricated parts are respectively fixed with the furnace body of the kiln, when one prefabricated part is damaged, the disassembly is faster, and the maintenance is convenient;

(4) the peephole prefabricated part resistant to smoke erosion is made of a certain steel fiber material, so that the strength and the heat-resistant temperature of the peephole prefabricated part are improved.

fig. 2 is a cross-sectional view of the present invention;

fig. 3 is a usage state diagram of the present invention.

Detailed Description

As shown in figures 1-2, a peephole prefab is washd to resistant flue gas, including concatenation form the same prefab 1 of four block shapes of cuboid, be equipped with channel 2 on a pair of parallel surface of 1 concatenation part of prefab, there is the length difference in the channel on two parallel surfaces, and cuboid prefab central authorities after the concatenation have tubaeform peephole 3. Preferably, the cross section of the channel consists of a rectangle and a right trapezoid, and the width of the rectangle is equal to the upper bottom of the right trapezoid. In order to enhance the combination degree of the peephole prefabricated part and the kiln body, a threaded counter bore 4 is arranged on the surface of the prefabricated part perpendicular to the channel, a bolt 5 is screwed in the counter bore 4, a nut 6 is fixed at the end part of the bolt 5 positioned outside the counter bore, and a gasket 7 is additionally arranged between the nut 6 and the prefabricated part 1. In order to enhance the strength and heat temperature resistance of the preform, the preform contained 3% steel fibers.
