Summary of the invention
At the problem that above-mentioned prior art exists, the utility model provides a kind of improved limekiln "T"-shaped burning beam, to reduce the percolation ratio of beam body conduction oil, prolongs the service life of burning beam.
The "T"-shaped burning beam in the limekiln that the utility model provides, mainly constitute by casing and case top, fuel conduit and air duct are arranged in the casing, fuel conduit is connected to the fuel nozzle of both sides burner, casing and case top are provided with the cavity of cooling medium circulation, and the cavity of case top cooling medium circulation is formed by upper plate, lower plate and the side plate system of enclosing.Described lower plate and side plate are surrounded by an iron plate, and the upper end of side plate and upper plate are Welding Structure.
The corrasion that the calcining materials that flows downward for reduction pushes up the burning beam case, two inferior horns and two last angles on case top are arc-shaped structure, two inferior horns on case top are equipped with wearing layer.
As selection, be provided with two fuel conduits in the casing, two fuel conduits are fixed with fixture, are installed in the air duct, and fuel nozzle is the extended type fuel nozzle.
Another kind is chosen as, and air port is established in the bottom of beam body, and air port is communicated with air duct.Air duct is divided into upper and lower two air ducts by dividing plate, and the air duct on top is communicated with the air outlet slit of burner, and the air duct of bottom is communicated with air port.
The employed cooling medium of the "T"-shaped burning beam of the utility model is water or conduction oil, does not get rid of the cooling medium that uses other.
Compared with prior art, the case of the "T"-shaped burning beam of the utility model pushes up each side and has only weld seam one, has reduced the probability of conduction oil seepage, helps limekiln long period safety in production, prolongs the service life of burning beam.The inferior horn and the last angle on case top are that arc-shaped structure and inferior horn are equipped with wearing layer, can alleviate the corrasion of calcining materials to the beam body.Adopt two fuel conduits and extended type fuel nozzle, install respectively, insert the burner mouth, fuel is burnt outside the burner mouth, combustion flame avoids burning out the case top of burner mouth and "T"-shaped burning beam away from the beam body wall, saves equipment investment and maintenance cost.Increase the air port of burning beam bottom, make part of fuel in the kiln body, disperse burning, reduce the combustion intensity of part, burner exit, improve the uniformity of calcination product, reduce and avoid local burning or give birth to burning, improve the quality of products.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
The utility model limekiln mainly is made of casing 9 and case top 8 with "T"-shaped burning beam as shown in Figure 1, and fuel conduit 5 and air duct 6 are arranged in the casing, and the both sides of casing are respectively equipped with 10 burners 4, and burner is made of fuel nozzle 11 and air outlet slit.Fuel conduit is connected to the fuel nozzle of burner, and air outlet slit is the gap around the fuel nozzle.Casing and case top are provided with the cavity 7 of cooling medium circulation, and the cooling medium that uses is conduction oil.The cavity of case top cooling medium circulation is formed by upper plate 1, lower plate 3 and the side plate system of enclosing, and described lower plate 3 and side plate are surrounded by an iron plate, and the upper end of side plate and upper plate are Welding Structure.Make the burning beam case push up every side and have only weld seam 2 one, reduce in the beam body probability of seepage under the conduction oil high temperature, reduce and avoid the burning beam leakage of oil and damage burning beam.Be the lime stone wearing and tearing beam body that minimizing flows downward, as shown in Figure 2, two inferior horns and two last angles on case top are circular arc, and two inferior horns on case top are equipped with wearing layer 10.
