Abstract

The invention provides application combined bricks for a smoke outlet and a nozzle of an anode furnace. The application combined bricks comprise outer ring bricks and inner ring bricks. The outer ring bricks are formed by combining multiple brick bodies in a radiating manner. The outer circle of the outer ring bricks is matched with brick bodies of the smoke outlet of the anode furnace. The inner circle of the outer ring bricks is circular. The inner ring bricks are of an annular structure formed by combining multiple brick bodies in a radiating manner. The outer circle of the inner ring bricks is matched with the inner circle of the outer ring bricks. The smoke outlet is formed by the inner circle of the inner ring bricks. The designed combined bricks are tightly matched and meshed with each other and the situation that the combined bricks are loosened due to high-temperature operation of the anode furnace is avoided; due to the adoption of the radiating combined bricks, the structural strength of the combined bricks is quite high, when the inner ring bricks expand at the high temperature, the combined bricks expand similarly, and a combined opening of the smoke outlet and the nozzle is firmer; and when the inner ring bricks shrink at the low temperature, due to the radiating brick form, the combined bricks are compact and firm similarly, and the service life of the anode furnace is prolonged to a great extent.

Description

Anode furnace smoke outlet and nozzle application modular tile

Technical field

The present invention relates to fire door field of structural design, specifically a kind of anode furnace smoke outlet and nozzle application modular tile.

Background technology

Build by laying bricks or stones in investigation to certain anode furnace scene, technician finds that anode furnace smoke outlet and anode furnace nozzle have been built by laying bricks or stones manyly needs improvements, it is former that to build design by laying bricks or stones be encompass circle with building by laying bricks or stones after side wall calculon scene is cut, brick for cutting is originally just smaller, after cutting reprocessing, brick shape is less and have many smaller trilateral bricks, mud one brush is simply used at some place being not easy to process, these slack and undisciplined structures all will have a strong impact on its bulk strength when anode furnace hot operation, thus have a strong impact on anode furnace work-ing life.

Further, because after original design cutting processing, brick is scrappy tiny, have and be manyly difficult to processing place, when the brick of peripheral cutting is around inner ring brick, owing to can not cut annular, the mortar joint very irregular around inner ring brick also substantially exceeds the magnesia chrome brick mortar joint requirement of 3mm, and some mortar joint has exceeded 10mm.Magnesia chrome brick can expand and shrink when high/low temperature transforms, such structure can be easy to make inner ring brick occur loosening, especially during high temperature, anode furnace will rotate, in the process, the inner ring loosened can be outstanding in stove due to stress, and repeatedly the inner ring brick in rear whole hole all can be out of shape fracture with processing calculon and collapse repeatedly.

Summary of the invention

The present invention is in order to solve the problem of prior art, provide the outlet of a kind of anode furnace smoke and nozzle application modular tile, very good structural strength is just had when normal temperature is built by laying bricks or stones, during high temperature, more can in anode furnace runs the thermal stresses of active balance exhanst gas outlet and nozzle bore, and in-situ processing amount and clip dust can be reduced, be conducive to lifting construction environment.

The present invention includes outer shroud brick and inner ring brick, its outer-loop brick is that radiativity combines by some fragments of brick, and the cylindrical of outer shroud brick and the fragment of brick of anode furnace air outlet agree with, and the inner circle of outer shroud brick is round; Described inner ring brick is some fragments of brick is the circular ring structure that radiativity combines, and the cylindrical of inner ring brick and the inner circle of outer shroud brick are agreed with, the interior round-formed air outlet of inner ring brick.

Further improvement, described outer shroud brick and inner ring brick are that radiativity combines by 24 pieces of bricks.

Beneficial effect of the present invention is:

1, the mutual close-fitting occlusion of the modular tile of design, can not be slack and undisciplined owing to occurring in anode furnace high temperature operation, owing to being made up of radial pattern modular tile, therefore, modular tile self just provides very high structural strength, because modular tile expands too during inner ring brick high-temperature expansion, therefore exhanst gas outlet and set of nozzles is made to heal up firmer, during low-temperature shrink, owing to being the brick of radial pattern, equally also can make modular tile close and firm, thus significantly improve anode furnace work-ing life.

2, be made up of corresponding 24 pieces of bricks, effectively eliminate calculon, enhance overall construction intensity simultaneously.

3, dust to be eliminated when building on-site cutting magnesia chrome brick by laying bricks or stones and cuts rear useless brick process to the harm of environment, decreasing the magnesia chrome brick supply of goods for cutting simultaneously, reducing magnesia chrome brick demand, cost-saving.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Embodiment

Below in conjunction with accompanying drawing, the invention will be further described.

Structure of the present invention as shown in Figure 1, comprises outer shroud brick and inner ring brick, and its outer-loop brick is that radiativity combines by some fragments of brick, and the cylindrical of outer shroud brick and the fragment of brick of anode furnace air outlet agree with, and the inner circle of outer shroud brick is round; Described inner ring brick is some fragments of brick is the circular ring structure that radiativity combines, and the cylindrical of inner ring brick and the inner circle of outer shroud brick are agreed with, the interior round-formed air outlet of inner ring brick.

The mutual close-fitting occlusion of modular tile of design, can not be slack and undisciplined owing to occurring in anode furnace high temperature operation, owing to being made up of radial pattern modular tile, therefore, modular tile self just provides very high structural strength, because modular tile expands too during inner ring brick high-temperature expansion, therefore exhanst gas outlet and set of nozzles is made to heal up firmer, during low-temperature shrink, owing to being the brick of radial pattern, equally also can make modular tile close and firm, thus significantly improve anode furnace work-ing life.

Outer shroud brick and inner ring brick are preferably that radiativity combines by 24 pieces of bricks, effectively can eliminate calculon, enhance overall construction intensity simultaneously.

Need according to the different type of furnace different pore size size science layout during design brick, appropriate design brick, design weight can not more than 25kg so that build by laying bricks or stones and carry, and the length and width height of design brick also will be considered conveniently can go forward one by one from manhole.

Embody rule approach of the present invention is a lot, and the above is only the preferred embodiment of the present invention, should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
