Description
Technical field
The utility model belongs to rotary kiln technical field, particularly a kind of cement rotary kiln burner abrasion-proof and refractory structure.
Background technology
Along with the fast development of China's new type nonaqueous cement technology, the new type nonaqueous cement production line all technical of China and energy consumption index all reach the level of production line of the same type in the world, create good economic benefit and social benefit at home.While technology of producing cement high speed development, Burner Technology, also in fast development, upgrades to " four-way " burner from " triple channel " burner, and the energy consumption index of cement producing line is reduced further, and energy-saving effect is more remarkable.But backwardness relative to the refractory material that burner matches, affects the running rate of cement kiln and the further raising of output, one of " bottleneck " of having become cement producing line long time running.
At present, refractory material average life of domestic new type nonaqueous cement production line is generally more than 12 months, and burner leading section one meter castable service life is mostly at 3-4 month, the life cycle of burner refractory material service life and other refractory materials is seriously asynchronous.And the Inspection cycle of cement producer was at about 6 months, therefore, cement plant ubiquity and is stopped the problem that burner front end castable changed by kiln temporarily, reduces running rate and the output of rotary kiln.
Burner is one of capital equipment of cement rotary kiln, burning till that it is clinker provides thermal source, ensure that raw material carry out Reactive Synthesis clinker at a sufficient temperature, and can according to technique need the length of flame and temperature are regulated, to meet need of production.Burner is formed by the metal pipe sleeve system of multiple different-diameter according to design is different, forms passage, circulation compressed air or fuel (see Fig. 1) in passage between every two metal tubes.Burner stretches in kiln head cover usually, and fuel directly sprays into rotary kiln combustion, and kiln hood case temperature is higher, and generally 1050 DEG C of-1250 DEG C of scopes, therefore burner top layer needs refractory material protection.
Current combustion device abrasion-proof structure is refractory concrete soil structure, by scene first at burner surface weld metal anchoring piece, then formwork is built and is formed, refractory concrete water content is high, baking is difficult to control, and by the restriction of formwork way, dilatation joint outwards other positions that to dewater square are difficult to reserve, can cause concrete premature rupture, service life is too short.
Summary of the invention
The purpose of this utility model is to provide a kind of cement rotary kiln burner abrasion-proof and refractory structure, solves that coal pipe castable is difficult to reserved dilatation joint, the upper and lower construction quality of coal pipe is uneven, and prefabricated component is difficult to the problems such as piecemeal outside coal pipe is fixing.
A kind of cement rotary kiln burner abrasion-proof and refractory structure, comprises burner cylindrical shell, prefabricated section, T-shaped pin, flange.Prefabricated section has 3-8 block, is connected with burner cylindrical shell by T-shaped pin; Flange, on the burner cylindrical shell of prefabricated section front end, prevents prefabricated section forward end from moving.
Prefabricated section has T-shaped groove, there is concaveconvex structure both sides.
Flange has 3-8 block.
T-shaped pin and flange are all connected with burner cylindrical shell by welding.
Traditional circular refractory concrete structure is designed to some pieces by this structure, design concaveconvex structure between two blocks of abrasion-proof and refractory prefabricated sections to seal, prevent heat smoke from invading, the one side that abrasion-proof and refractory prefabricated section contacts with burner cylindrical shell designs T-shaped groove, burner cylindrical shell welds T-shaped pin, abrasion-proof and refractory prefabricated section is stuck on T-shaped pin, after all installing, at burner cylindrical shell end face weld acting flange by fixing before and after abrasion-proof and refractory prefabricated section.
The manufacturing of abrasion-proof and refractory prefabricated section, toast and all complete at refractory factory, directly come into operation after in-site installation completes, solve castable refractory water content high, cannot toast, the problem that service life is short.
The utility model has the advantage of: this prefabricated component, without the need to on-the-spot formwork, is built, quick and easy for installation; Prefabrication construction quality is good, stable performance; Piecemeal is installed, and effectively can reduce crackle and come off.
