Background technology

Card neck is one of important component part of glass furnace, at the melting end of melting furnaces and a position of the shrinkage in width between the cooling end, itself and water coolant bag are used, can reduce temperature of glass liquid, separate the atmosphere between melting end and the cooling end, and can also feed glass liquid flow to the flow of cooling end from melting end.

The temperature at card neck place is higher, nearly 1300 ℃～1400 ℃, the sealing at card neck top generally can adopt arch structure 1 to seal, in the prior art, as shown in Figure 1, this arch structure 1 " adopts flat arch structure; be that arch structure 1 " on each piece refractory brick 12 " is all made zig-zag; refractory brick 12 " engagement each other more, form an integral body, utilize steel structure 11 " with intermeshing refractory brick 12 " to hang again, the arch structure 1 of the type " exists following shortcoming: under the long term of high temperature and sulphur and alkaline atmosphere; arch structure 1 " refractory brick 12 " can be nibbled gradually; be etched; after long-time; refractory brick 12 " owing to expand and the erosive dual function, its engagement each other can break away from, thereby cause refractory brick 12 in " falling in the glass metal in the melting furnaces; cause pollution; have a strong impact on the quality of glass metal, this arch structure 1 ", need steel structure 11 and " come the refractory brick after the engagement is hung; so need " carry out cooling process to steel structure 11 to glass metal, produce energy consumption, and steel structure 11 " can get rusty at high temperature, also can produce potential and pollute.

The utility model content

The purpose of this utility model is to provide a kind of arch structure of glass melter card neck, be intended to solve fragment of brick in the arch structure of the prior art drop easily and influence glass quality, the arch structure need be carried out the fixed problem with the steel structure.

The utility model is achieved in that a kind of arch structure of glass melter card neck, comprises the fragment of brick that several fit together in regular turn, and described fragment of brick is wedge shape, and the outermost fragment of brick of described arch structure is connected on the pool wall of described melting furnaces.

Further, described fragment of brick comprises stub end and little head end, and the stub end of adjacent fragment of brick is fitted mutually in the described arch structure, and little head end is fitted mutually, and the placement that is big top and small bottom of described fragment of brick, is combined to form arch.

Further, described fragment of brick is mullite brick or silica brick or Corhart Zac-block.

Compared with prior art, the fragment of brick of the arch structure in the utility model is a wedge shape, and outermost fragment of brick is subjected to the squeeze in the outside in the arch structure, like this, fragment of brick in the arch structure can be firm combine, form domes, even in long-time hot environment, be subjected to the erosion of sulphur and alkaline atmosphere, fragment of brick wherein can not come off yet, thereby can not fall in the glass metal in the melting furnaces, can not have influence on the quality of glass, and this arch structure do not need the steel structure to fix, thereby reduce the energy consumption of melting furnaces, increase the working space of card neck, increase the stability and the security of melting furnaces.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

The utility model provides a kind of arch structure of glass melter card neck, comprises the fragment of brick that several fit together in regular turn, and described fragment of brick is wedge shape, and the outermost fragment of brick of described arch structure is connected on the pool wall of described melting furnaces.

In the utility model, the fragment of brick in the arch structure is wedge shape, and fits together mutually, thereby fragment of brick can not drop, and can not have influence on the quality of glass, and the arch structure do not need the steel structure to fix, and reduces the melting furnaces energy consumption, improves melting furnaces stability and security.

Below in conjunction with concrete accompanying drawing realization of the present utility model is described in detail.

Shown in Fig. 3～5, a preferred embodiment that provides for the utility model.

Shown in Fig. 3～5, card neck is one of important component part of glass furnace, it is at the melting end of melting furnaces and a position of the shrinkage in width between the cooling end, can be used with water coolant bag 4, reduce temperature of glass liquid, separate the atmosphere between melting end and the cooling end, and can also feed glass liquid flow to the flow of cooling end from melting end.

The temperature at card neck place is higher, and nearly 1300 ℃～1400 ℃, the sealing at card neck top generally can adopt arch structure 1 to seal, and as shown in Figure 5, arch structure 1 one ends are connected to and are resisted against behind the melting end on the gable 3, and its other end is resisted against on the water coolant bag 4.

Shown in Fig. 3～4, arch structure 1 comprises several fragments of brick that is wedge shape 11, several fragments of brick 11 fit together in regular turn, rely on mutual frictional force to compress applying, formed the integral body of arch structure 1, these arch structure 11 integral body are arch shape, the fragment of brick 11 in two outsides is connected to respectively on the pool wall fragment of brick 2 of glass melter, because fragment of brick 11 is wedge shape, fit together mutually, and the fragment of brick 11 in two outsides pushes by extraneous butt, thereby this arch structure 1 can form a firm integral body, in the use of long term high temperature, even be subjected to the erosion of sulphur and alkaline atmosphere, the phenomenon that the fragment of brick 11 of the wedge shape that fits together mutually also can not occur dropping, so, fragment of brick 11 on the arch structure 1 just can not fallen in the interior glass metal of melting furnaces, can not influence the quality of glass, and this arch structure 1 do not need the steel structure to come arch structure 1 is fixed, can reduce the energy consumption of melting furnaces, increase the working space at card neck place, and help improving the long-term stability and the safety performance of melting furnaces.

Particularly, the fragment of brick 11 of this wedge shape has stub end 111 and the microcephaly holds 112, in arch structure 1, the stub end 111 of adjacent fragment of brick 11 fits together mutually, and the microcephaly holds 112 also to fit together mutually, and fragment of brick 11 placement that is big top and small bottom, the stub end 111 that is fragment of brick 11 is placed up, its microcephaly holds 112 to place down, like this, and the structure that whole arch structure 1 is big up and small down, like this, fragment of brick 11 in the arch structure 1 can not come off, and under the effect of external force, fitting can be more and more tighter.

The fragment of brick 11 of wedge shape can be mullite brick piece 11 in above-mentioned, also can be silica brick piece 11 or electric fused zirconium corundum fragment of brick 11.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
