Abstract
The invention discloses a hearth refractory material structure of a carbon roasting furnace. The hearth refractory material structure of the carbon roasting furnace comprises hearth heavy refractory materials or concrete, light heat-insulation bricks, hearth blocks and heavy refractory bricks at the bottom of a flame path wall, and the hearth heavy refractory materials or the concrete are connected with the heavy refractory bricks at the bottom of the flame path wall by a plurality of support columns. The hearth refractory material structure in the technical scheme has the advantages that problems that the shapes of bricks are multiple, a hearth structure is over complicated and construction efficiency is low in the prior art are solved, and problems of serious accidents such as that heat-insulation bricks are often broken and a flame path wall is subsided during usage of an existing carbon roasting furnace due to the fact that the hearth light heat-insulation bricks are low in strength and the like are also solved.
Description
Technical field
The present invention relates to fire resisting material field, specifically, be a kind of structure of refractory that is used in the carbon baking furnace furnace bottom specially and with the structure of refractory assembly of this structurally associated.
Background technology
[0002] current, carbon baking furnace bottom refractory structure is as depicted in figs. 1 and 2.When 1. building by laying bricks or stones, earlier on the furnace bottom concrete plane, spread which floor chamotte brick, be generally layer 2-4, leave and take the wide groove of 200～300mm, and then the furnace bottom piece (brick G) that will be shaped as cuboid builds by laying bricks or stones on groove, form built on stilts furnace bottom.2. (total height is generally at 400～600mm) light thermal insulation fire-resistant bricks on the furnace bottom piece, to build 6～10 layers by laying bricks or stones.On the light thermal insulation fire-resistant brick, build quirk wall bottom heavy refractory brick (brick number: D) again by laying bricks or stones.3. above-mentioned furnace bottom piece (brick number: G) with heavy refractory brick (brick number: D); Be building the prefabricated section furnace bottom piece of brick machine mechanical pressing (or with) of moulding and pass through the heavy refractory brick that high temperature burns till with pours of designing units such as Shenyang magnalium designing institute and Kweiyang magnalium designing institute design, its brick number is labeled as " G " and " D " respectively.Below unified furnace bottom piece and the D shaped brick of abbreviating as.The shape of this furnace bottom piece and D shaped brick is cuboid.(as depicted in figs. 1 and 2).
There are several like this problems in the polycrystalline substance of this carbon baking furnace: the one, and brick shape is many, and bottom construction is too complicated, and it is low to build efficient by laying bricks or stones.The 2nd, owing to reasons such as furnace bottom light-weight insulating brick intensity are low, in the use of carbon baking furnace, fragmentation often appears in insulating brick, causes serious accidents such as the sinking of quirk wall takes place.Therefore, must innovate, design to carbon baking furnace bottom refractory structure and with the structure of refractory assembly of this structurally associated, make build by laying bricks or stones efficient higher, use safer.
Summary of the invention

The specific embodiment
The present invention provides a kind of carbon baking furnace bottom structure of refractory; This carbon baking furnace bottom structure of refractory comprises: the heavy refractory brick 5 of furnace bottom heavy refractory material or concrete 1, light-weight insulating brick 4, furnace bottom piece 3 and quirk wall bottom has some support columns to be connected between said furnace bottom heavy refractory material or the concrete 1 heavy refractory brick 5 bottom said quirk wall; To shown in Figure 11, said some support columns 11 are arranged in the bottom of the heavy refractory brick of said quirk wall bottom along quirk wall length direction discontinuous like Fig. 3.The distance at the interval of this layout can be impartial, also can be unequal.Said some support columns 11 connected modes are that the laid dry formula is connected or the connection of mother-son mouth formula with bonded.Said some support columns 11 also can be the bottoms that continous way is arranged (promptly one arrange near a ground) the heavy refractory brick bottom the said quirk wall along quirk wall length direction.
Like Figure 16 and shown in Figure 17, said support column 11 can be rectangular cylinder, also can be cylinder.The cross section of said support column 11 is other cubes such as polygon also.The cross section up and down of said support column can be an equidimension, also can be equidimension not.Said support column can be solid, also can be hollow, preferred solid rectangular cylinder.The thickness of this preferred solid rectangular post can equate with the wall thickness dimension of quirk wall, also can be unequal, and is preferred equal, such as all being 110mm.Like Figure 20 and shown in Figure 21,, change the furnace bottom piece 3 that is shaped as " cuboid " that was used for built on stilts furnace bottom originally into " stool " formula furnace bottom piece for improving efficiency of construction.Like this, need cover on the groove that bottom refractory brick is built by laying bricks or stones with cuboid furnace bottom piece originally, could form the aerial construction 10 of furnace bottom.Now, only need to use a kind of " stool " formula furnace bottom piece, just can form the aerial construction 10 of furnace bottom." stool face " and " stool leg " can be square, cuboid or other stereochemical structures, preferred cuboid." stool face " and " stool leg " can straight forming together, also can be to produce respectively earlier, assemble then, bond together.Furnace bottom piece 3 preferred stool faces of the present invention are rectangular structure, and the stool leg is a rectangular structure, is inverted U-shaped body between the said stool leg.
Like Figure 22 and shown in Figure 23, because low, the easy fragmentation of light-weight insulating brick intensity for the safety of furnace bottom, should reduce the consumption of light-weight insulating brick as far as possible.The present invention has invented two kinds of methods and has realized this purpose: the one, and the withstand voltage lightweight composite bed 13 of compound one deck (being high-intensity lightweight composite bed) on furnace bottom piece 3 upper surface of (comprising furnace bottom pieces such as stool formula furnace bottom piece) forms compound furnace bottom piece.The 2nd, with the machine briquetting (brick) that the original heavy refractory brick (D shaped brick) that needs high temperature to burn till changes casting preformed block into or need not burn till, be called for short D type piece.Then, the withstand voltage lightweight composite bed 13 of compound one deck on the basal surface of D type piece forms compound D type piece.
This high-intensity lightweight composite bed can directly be molded over together with methods such as cast or machine pressures with above-mentioned furnace bottom piece 3, stool formula furnace bottom piece, D shaped brick, D type piece, compound D type piece, also can be to bond together after producing respectively.
Owing to adopt the compound layer of high strength to replace the part light-weight insulating brick in the original structure, therefore when keeping heat insulation effect, reduced the quantity of furnace bottom insulating brick, increased the security of furnace bottom.The intensity of high-strength light composite bed should be greater than light-weight insulating brick.The proportion of high-strength light composite bed preferably in d≤0.8～≤1.5g/cm
3Between, its material is preferably aluminosilicate property.
Protection domain of the present invention is not limited to the foregoing description, and every conspicuous technology distortion of doing according to know-why of the present invention all falls within protection scope of the present invention.
