1. kiln tail, 2. cylinder of rotary kiln, 3. kiln hood, 4. support, 5. charging apertures, 6. refractory lining brick in kiln, 7. drive, 8. gear wheel, 9. wheel rim, 10. carrying roller in figure, 11. cartridges, 12. discharge gates, 13. cooling cylinders, 14. post-blast machines, 15. antispray layers.
Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of splashproof rotary kiln as shown in Figure 1, there is kiln tail 1, cylinder of rotary kiln 2 and kiln hood 3, kiln tail 1 is fixedly mounted on support 4, kiln tail 1 is provided with charging aperture 5, be provided with by refractory lining brick 6 in the fixing kiln of anchoring piece in cylinder of rotary kiln 2, the outer surface of cylinder of rotary kiln 2 is provided with gear wheel 8, gear wheel 8 drives running by drive 7, the both sides of gear wheel 8 are equipped with wheel rim 9, the lower end of wheel rim 9 is provided with carrying roller 10, kiln hood 3 is provided with cartridge 11, the lower end of kiln hood 3 is provided with discharge gate 12, discharge gate 12 is connected with cooling cylinder 13, antispray layer 15 is provided with in cylinder of rotary kiln 2, kiln tail 1 and between kiln hood 3 with cylinder of rotary kiln 2 for movable sealing is connected, described movable sealing syndeton is nested construction, cylinder of rotary kiln 2 is a cylinder be welded into by steel plate, cylinder of rotary kiln 2 is provided with post-blast machine 14.
The main body of concrete rotary kiln is a cylinder be welded into by steel plate, inner block refractory brick 6, immediately below rotary kiln, also need installation similar but the cooling cylinder 13 that diameter is less and length is shorter to cool bright red calcining material, negative pressure 4 in thermograde in kiln, the length of burning zone, feeding quantity and kiln is mainly controlled in the technological operation of rotary kiln well.High temperature is produced after the volatile combustion that the fuel sprayed in kiln by cartridge 11 and raw material are discharged, three temperature band are formed in kiln, preheating zone, burning zone and salband, preheating zone is kiln body total length direction near a section of kiln tail, the charge pipe of raw material above kiln tail 1 enters in kiln, kiln tail 1 temperature is generally 800-900 DEG C, and raw material moves from kiln tail 1 to kiln hood 3 first through preheating zone heating, discharges moisture and part volatile matter.Burning zone is the highest one section of kiln temperature, and generally reach 1200 ~ 1300 DEG C, high-temperature calcination can reach about 1450 DEG C.The length of burning zone is subject to the impact of negative pressure in kiln body length and kiln, account for the half of kiln body length under normal circumstances, the temperature of burning zone is relevant with the quantity of spray people fuel and calorific value, simultaneously whether Thorough combustion is relevant with spraying into fuel and volatile matter, during the petroleum coke that particularly calcining volatile matter is larger, the burning of fuel and volatile matter all needs a large amount of air, there is no enough air-breathings, kiln temperature rises not get on, but air capacity too much can increase again the oxidation loss of raw material in kiln, the air only sucked by kiln hood 3 during calcined petroleum coke is inadequate, need in the middle part of kiln body, to increase post-blast machine 14 with supplementary air, raw material generally only has 40 ~ 60min by the time in the rotary kiln of length 36m, length and the speed of advancement of raw material in kiln of rotary kiln is depended on by the length of time, and the speed of advancement of raw material in kiln and the rotating speed of kiln, several the factors such as the inclination angle of kiln body and the raw material Dynamic repose angle in kiln are relevant, the temperature of burning zone should be controlled well in order to reach higher burning quality, regulate the speed of advancement of raw material in kiln, when reaching set point of temperature condition, the output of a rotary kiln depends primarily on the bulk density of raw material, the pack completeness of raw material in kiln and speed of advancement three factors, directly contact with thermal-flame when carbonaceous raw material is calcined in rotary kiln, therefore oxidation loss is larger, the oxidation loss of calcining refinery coke by rotary kiln is utilized to be generally 10% ~ 12%.
Above-mentioned embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
