Abstract
The utility model relates to a prefabrication brick for a rotary kiln tail lock mouth. The prefabrication brick comprises a prefabrication brick body and a chute arranged on the prefabrication brick body. The prefabrication brick body is a cuboid with a quadrangular section. The upper surface of the prefabrication brick body is provided with an overflowing face. The lower surface of the prefabrication brick body is provided with an inclined plane connecting face and a horizontal connecting face. An inclined plane connecting anchoring part and a horizontal plane connecting anchoring part are respectively arranged on the inclined plane connecting face and the horizontal connecting face. The inclined plane connecting anchoring part and the horizontal plane connecting anchoring part can be directly welded to a kiln tail lock mouth inclined plane and a rotary kiln barrel body so that fireproof materials are convenient to replace. Grooves or flanges on four faces between the upper surface and the lower surface of the prefabrication brick body form curve sealing so that thermal loss is reduced and integrity is strengthened. The shape of the overflowing face is arc so that mobility of the materials is increased, accumulation of the high-temperature materials on corners and impact on the fireproof materials are reduced, and service life of the fireproof materials at an included angle of the kiln tail lock mouth is prolonged.
Description
Technical field
The utility model belongs to technical field of industrial furnaces, is specifically related to a kind of rotary kiln preformed bricks, particularly a kind of rotary kiln fore shaft preformed bricks.
Background technology
Rotary kiln refers to rotary kiln, and rotary kiln becomes 3 to 5 degree angles with horizontal plane.Rotary kiln is multiplex in cement kiln, chemical metallurgy kiln and limekiln etc.Cement kiln is mainly used in calcination of cement clinker.The chemical metallurgy kiln then is mainly used in the poor iron ore magnetic roasting of metallurgy industry steel plant; Chromium, josephinite oxidizing roasting; Refractory factory roasting high-aluminium vanadine ore deposit and aluminium manufacturer's roasting grog, aluminium hydroxide; The class mineral such as chemical plant roasting chrome ore and chromite ore fine.
In the rotary kiln body, kiln tail fore shaft is to amplify gradually to fore shaft and cylindrical shell junction direction, therefore with the cylinder of rotary kiln connecting portion angle is arranged, material enters kiln tail fore shaft through after the preheating from the chute landing, kiln tail fore shaft refractory material is owing to often being subject to the impact with thermal current of washing away of material under the high temperature, this place's refractory material is on the low side service life, need to often stop kiln and repair.
Therefore, produce a kind of simple in structurely, easy to maintenance, simple to operate, can reduce material in the accumulation of angle, be easy to produce, can improve the rotary kiln rotary kiln fore shaft preformed bricks in service life, have wide market prospects.
Summary of the invention
For the deficiencies in the prior art, the utility model provide a kind of simple in structure, easy to maintenance, simple to operate, can reduce material in the accumulation of angle, be easy to produce, can improve the rotary kiln rotary kiln fore shaft preformed bricks in service life.
The technical solution of the utility model is achieved in that a kind of rotary kiln fore shaft preformed bricks, comprise the preformed bricks body, be arranged on the chute on the preformed bricks body, described preformed bricks body is that cross section is tetragonal cuboid, the upper surface of preformed bricks body is provided with spillwag chute, the lower surface of preformed bricks body is provided with inclined-plane joint face and horizontal connecting surface, is respectively arranged with inclined-plane connection anchoring element and horizontal plane connection anchoring element at inclined-plane joint face and horizontal connecting surface.
Described spillwag chute be shaped as arc.
Described inclined-plane connection anchoring element and horizontal plane connection anchoring element are list structure.
The setting party of described chute is to being parallel to each other with inclined-plane joint face and horizontal connecting surface.
Described inclined-plane connection anchoring element and horizontal plane connection anchoring element all are at least one.
The utlity model has following good effect: at first this product structure is simple, comprise the preformed bricks body, be arranged on the chute on the preformed bricks body, described preformed bricks body is that cross section is tetragonal cuboid, the upper surface of preformed bricks body is provided with spillwag chute, the lower surface of preformed bricks body is provided with inclined-plane joint face and horizontal connecting surface, is respectively arranged with inclined-plane connection anchoring element and horizontal plane connection anchoring element at inclined-plane joint face and horizontal connecting surface; Secondly, the utility model inclined-plane connection anchoring element and horizontal plane connection anchoring element can directly be welded on kiln tail fore shaft inclined-plane and the cylinder of rotary kiln, and the problem of unsuitable formwork supporting plate has made things convenient for the replacing of refractory material when having solved original employing castable and building by laying bricks or stones; Form bent envelope at the upper surface of preformed bricks body and the groove on four faces between the lower surface or flange, reduce thermal losses, increased simultaneously globality; The utility model spillwag chute be shaped as arc, increased the flowability of material, reduce high-temperature material accumulation around the corner and to the impulsive force of refractory material, increased the service life of kiln tail fore shaft angle refractory material.

The specific embodiment
As shown in Figure 1, 2, 3, a kind of rotary kiln fore shaft preformed bricks, comprise the preformed bricks body, be arranged on the chute 7 on the preformed bricks body, described preformed bricks body is that cross section is tetragonal cuboid, the upper surface of preformed bricks body is provided with spillwag chute 2, the lower surface of preformed bricks body is provided with inclined-plane joint face 3 and horizontal connecting surface 4, is respectively arranged with inclined-plane connection anchoring element 5 and horizontal plane connection anchoring element 6 at inclined-plane joint face 3 and horizontal connecting surface 4.
Described spillwag chute 2 be shaped as arc.Described inclined-plane connection anchoring element 5 and horizontal plane connection anchoring element 6 are list structure.The setting party of described chute 7 is to being parallel to each other with inclined-plane joint face 3 and horizontal connecting surface 4.Described inclined-plane connection anchoring element 5 and horizontal plane connection anchoring element 6 all are at least one.
In use, the utility model horizontal plane connection anchoring element 6 directly is welded on the fore shaft steel plate 1, inclined-plane connection anchoring element 5 and be welded on cylinder of rotary kiln.The utility model is placed on kiln tail fore shaft and cylinder of rotary kiln angle, and after preformed bricks and rotary kiln body brick were installed, the problem of unsuitable formwork supporting plate had made things convenient for the replacing of refractory material when having solved original employing castable and building by laying bricks or stones; Form bent envelope at the upper surface of preformed bricks body and the groove on four faces between the lower surface or flange, reduce thermal losses, increased simultaneously globality; The utility model spillwag chute be shaped as arc, increased the flowability of material, reduce high-temperature material accumulation around the corner and to the impulsive force of refractory material, increased the service life of kiln tail fore shaft angle refractory material.
