Abstract

The utility model provides a fire grate for a bauxite combustion chamber, and solves the problem of aggregation or lack of materials in the combustion chamber in the prior art. The fire grate for the bauxite combustion chamber comprises a first transverse rod and a second transverse rod, wherein the first transverse rod and the second transverse rod are fixed on vertical rods; a blanking slope is fixed at the bottoms of the vertical rods. During use, the fire grate is placed into an arch wall of the combustion chamber, and materials falling inside a vertical kiln are blocked by the fire grate firstly, pass through gaps among the first transverse rod, the second transverse rod and the vertical rods, and flow into the combustion chamber slowly. The materials falling off from the top of the vertical kiln do not fall into the combustion chamber in batches after being blocked by the fire grate, thereby preventing the combustion chamber from being blocked; meanwhile, the material flow into the combustion chamber continuously without causing deficiency of the materials.

Description

The fiery double-edged fine-toothed comb in a kind of bauxite combustion chamber

Technical field

The utility model relates to a kind of bauxite combustion chamber, is specifically related to a kind of fiery double-edged fine-toothed comb that is placed on a combustion chamber arch ancient piece of jade, round, flat and with a hole in its centre.

Background technology

At present, the bauxite over 85% is for producing aluminium oxide, then produces metallic aluminium, and 10% aluminium oxide for the production of nonmetal use is remaining for non-smelting bauxite application.In producing the process of aluminium oxide, need to calcine bauxite, during calcining, need to use calcining kiln.

Using in the market more calcining kiln is bauxite shaft kiln, and the material at shaft kiln top directly falls into kiln bottom from eminence, and material enters combustion chamber and burns.Yet in dropping process, because material itself has agglomeration, also transfer in batch when convey materials downwards in addition, this cause material in batches fall into combustion chamber, likely cause disappearance material in combustion chamber obstruction or combustion chamber, the normal operation that impact is produced.And when combustion chamber is stopped up, workman is also more difficult in cleaning material.

Utility model content

The utility model proposes the fiery double-edged fine-toothed comb in a kind of bauxite combustion chamber, solved the problem that in prior art, in combustion chamber, material is reunited or lacked.

To achieve these goals, the technical solution of the utility model realizes in the following manner:

The fiery double-edged fine-toothed comb in bauxite combustion chamber, comprises the first cross bar and the second cross bar, and the first cross bar and the second cross bar are fixed on montant, in the bottom of montant, are fixed with blanking slope.

On described the first cross bar, be connected with bearing diagonal.

Described bearing diagonal is hinged or be welded on the first cross bar.

Described bearing diagonal is at least two.

On described the first cross bar, be fixed with stock.

The utility model is placed in an arch ancient piece of jade, round, flat and with a hole in its centre for combustion chamber while using, and when material falls into shaft kiln inside, first by the utility model, is blocked, and material is by the flowing in combustion chamber slowly of the space between the first cross bar, the second cross bar and montant afterwards.After the material falling from shaft kiln top is blocked by fiery double-edged fine-toothed comb of the present utility model, can not fall in batches combustion chamber, so combustion chamber can not stop up, the continual flowing in combustion chamber of material simultaneously, also can not cause the disappearance of material.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is that schematic diagram is looked on the right side of Fig. 1.

Wherein, 1. the first cross bar, 2. bearing diagonal, 3. the second cross bar, 4. stock, 5. montant, 6. blanking slope.

The specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not paying the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

As depicted in figs. 1 and 2, the fiery double-edged fine-toothed comb in a kind of bauxite combustion chamber, comprises that the first cross bar 1 and the second cross bar 3, the first cross bars 1 and the second cross bar 3 are fixed on montant 5, are fixed with blanking slope 6 in the bottom of montant 5.

The utility model operation principle is as follows: in the time of use, on the arch ancient piece of jade, round, flat and with a hole in its centre that the end of the first cross bar 1, the second cross bar 3 and montant 5 are fixed on combustion chamber, first the material that shaft kiln top falls is blocked by the first cross bar 1, the second cross bar 3 and montant 5,6 to flow into burning inner from the gap of the first cross bar 1, the second cross bar 3 and montant 5, along blanking slope for material afterwards, there will not be combustion chamber clogging.

On described the first cross bar 1, be connected with bearing diagonal 2, when installing, by the end support of bearing diagonal 2 on the fixtures such as wall around of combustion chamber, can be so that fiery double-edged fine-toothed comb of the present utility model be fixing more firm.

As required, can be by described bearing diagonal 2 hinged or be welded on the first cross bar 1.

In the utility model, described bearing diagonal 2 is at least two.

As preferably, on described the first cross bar 1, be fixed with stock 4, according to the needs of real work, staff utilizes stock 4 can install or lay down the utility model, in order to avoid be subject to the impact of high temperature in combustion chamber when directly contacting fiery double-edged fine-toothed comb.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
