Abstract

The utility model discloses a cathode roasting furnace gas well structure, which comprises a furnace wall of the cathode roasting furnace. Concrete pouring blocks are built at the position of a gas well inside the furnace wall, a tenon is arranged on the upper surface of each concrete pouring block, and a groove is arranged on the lower surface of each concrete pouring block. Two concrete pouring blocks which are adjacent vertically are connected with each other through the tenon and the groove, and a layer of alumina silicate fiber blanket is filled between the two concrete pouring blocks. The cathode roasting furnace gas well structure fully abandons a traditional mode that high-alumina bricks and refractory mortar are adhesively bonded and built block-by-block. Only one layer of alumina silicate fiber blanket is filled between the two vertically adjacent concrete pouring blocks to perform sealing and leveling, and centering, positioning and build-in are operated by the tenons and the grooves of vertically adjacent concrete pouring blocks, thereby being convenient to operate, greatly saving installation time and firmly stabilizing the structure. The cathode roasting furnace gas well structure has the advantages of having short construction period, good structure stability, long service life, convenience in maintenance, low production cost and the like.

Description

A kind of cathode baking furnace gas well structure
Technical field
The utility model relates to a kind of cathode baking furnace gas well structure, belongs to cathode baking furnace gas well manufacture technology field.
Background technology
The gas well of cathode baking furnace is used for arriving furnace bottom by high-temperature gas, and at present, in the prior art, the gas well of cathode baking furnace adopts high-alumina brick and bonding the building by laying bricks or stones of fire clay block-by-block to form usually.Because when work, the gas temperature that gas well passes through is very high, thereby the gas well that adopts prior art to build by laying bricks or stones often exists problems such as easy generation cracking and modification, and repairs to get up also relatively to waste time and energy, and the process that also needs a drying after laying, the reparation duration is longer.Therefore existing cathode baking furnace gas well preparation method still is not ideal enough.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, be difficult for producing cracking or distortion when using and service life is long, easy to maintenance, the cathode baking furnace gas well structure of construction period weak point, to overcome the deficiencies in the prior art.
The utility model is achieved in that a kind of cathode baking furnace gas well structure of the present utility model, the furnace wall that comprises cathode baking furnace, gas well position in furnace wall has been built the concrete casting castable by laying bricks or stones, on the upper surface of concrete casting castable, be provided with tenon, lower surface at the concrete casting castable is provided with groove, two neighbouring block concrete castables interconnect by tenon and groove, and are lined with one deck alumina silicate fibre blanket between neighbouring two block concrete castables.
Medial surface bottom at above-mentioned concrete casting castable is provided with the hook groove.
Simultaneously in above-mentioned concrete casting castable, be provided with reinforcing bar.
Between aforesaid concrete casting castable and furnace wall, be provided with the gap, and in the gap, be filled with aluminosilicate fiber cotton.
Owing to adopted technique scheme, when the utility model is made gas well in the furnace wall of cathode baking furnace, adopt the concrete casting castable in furnace wall, to build the cathode baking furnace gas well by laying bricks or stones, when building by laying bricks or stones at adjacent pad one deck alumina silicate fibre blanket between the two block concrete castables up and down.The utility model has been abandoned traditional employing high-alumina brick and the bonding mode of building by laying bricks or stones of fire clay block-by-block fully, owing to need not build fire clay between the concrete casting castable about of the present utility model, only filling up one deck alumina silicate fibre blanket seals and levels up, and rely on the tongue-and-groove of concrete casting castable building block up and down to carry out centering, location and build-in, thereby it is not only easy to operate, set-up time is saved greatly, and Stability Analysis of Structures is firm, the utility model is equipped with heat-resisting reinforcing bar again in the concrete casting castable in addition, so the utility model is the brick gas well structure that globality intensity or non-deformability all are better than prior art greatly.So, the utility model compared with prior art, the utility model not only have the construction period short, structural stability good, when work is difficult for producing cracking or the advantage of distortion, long service life, but also has advantages such as simple in structure, easy to maintenance, that cost of manufacture is lower.Through evidence, adopt the utility model can effectively solve the existing common problem of brick gas well in the prior art.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Description of reference numerals: 1-furnace wall, 2-aluminosilicate fiber cotton, 3-concrete casting castable, 3.1-tenon, 3.2-groove, 3.3-hook groove, 4-alumina silicate fibre blanket, 5-reinforcing bar.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment of the present utility model: when in the furnace wall 1 of cathode baking furnace, making gas well, adopt the utility model to implement, promptly adopt traditional cement and mortar material to precast concrete casting castable 3 earlier, in order to reach higher intensity, can be in concrete casting castable 3 configuration reinforcement 5, be made into the armored concrete castable, on the upper surface of concrete casting castable 3, produce simultaneously tenon 3.1, on the lower surface of concrete casting castable 3, produce groove 3.2, in order to use time lifting convenient, also produce hook groove 3.3 simultaneously in the medial surface bottom of concrete casting castable 3; Gas well position in furnace wall 1 adopts concrete casting castable 3 to carry out traditional gas well shape to build by laying bricks or stones then, when building by laying bricks or stones, two neighbouring block concrete castables 3 are interconnected by tenon 3.1 and groove 3.2, and between neighbouring two block concrete castables 3, fill up one deck alumina silicate fibre blanket 4; The expansion of gas well when helping high temperature in use, prevent gas well distortion or cracking better, and the requisite space when staying dismounting, during making, between concrete casting castable 3 and furnace wall 1,3~20 mm clearance are set, and aluminosilicate fiber cotton 2 in the gap, filling.Used alumina silicate fibre blanket 4 and aluminosilicate fiber cotton 2 can directly adopt finished-product material of the prior art to get final product.
