Description
Technical field
The utility model relates to a kind of cement manufacture plant, especially relates to a kind of grate-cooler one Room cooling structure.
Background technology
Grate-cooler is the critical host equipment in the grog firing system of cement plant, and its major function is that clinker is carried out to cooling, conveying; For rotary kiln and dore furnace etc. provides hot-air, be the capital equipment of firing system recuperation of heat simultaneously.Along with developing rapidly of Modern New cement produced with the dry method technology & equipment, and the technology of cement clinker grate cooler improves constantly, and high-effect, reliable grog grate-cooler becomes the key of guaranteeing system production capacity.
At present, in manufacture of cement, the cooling velocity of high temperature chamotte is one of key measure affecting Cement Quality, in order to realize the cooling fast of high temperature chamotte, existing high temperature chamotte cooling structure all adopts grate structure, the mobile grog that promotes by grate moves forward on the one hand, force blowing to realize cooling, and ventilation apparatus all adopts centrifugal blower by the air port in grate to grog inside simultaneously.There is following problem in existing high temperature chamotte cooling structure: the one, and high temperature chamotte is from charging aperture enters grate-cooler, in high temperature chamotte moving process in grate skewness, high temperature chamotte is in different positions, not identical to the resistance of cooling air yet, as cooling with the centrifugal blower of power in adopted, cause high temperature chamotte inhomogeneous cooling, the waste of build-up of pressure loss simultaneously and the energy.Secondly, due in high temperature chamotte moving process in grate skewness, make cooling air temperature on the low side, cause grog utilization rate of waste heat low, operation easier has certain increase, energy consumption higher.Existing high temperature chamotte cooling structure can not carry out high temperature chamotte fully cooling mostly, due to cooling insufficient, grog can not get chilling, can not effectively stop tricalcium silicate to the conversion of dicalcium silicate, not only restrict the raising of clinker strength, also weaken the wearability of grog, increase power consumption and the material consumption of grinding, it is high that while clinker goes out grate-cooler temperature, cause environment temperature high, equipment failure rate is high, and maintenance of equipment, maintenance cost are high, and production cost is high.
Utility model content
The object of the utility model is: for the deficiencies in the prior art, propose a kind of grate-cooler one Room cooling structure, overcome cooling insufficient, inhomogeneous, the shortcoming that the pressure loss is large of existing grate-cooler.
The technical solution of the utility model is:
A kind of grate-cooler one Room cooling structure, comprise housing and whole fixing cooling grate plate, described housing one end is provided with charging aperture, enclosure interior is provided with wallboard, described wallboard is divided into upper box, middle casing and lower box by housing, the air inlet that described upper box, middle casing and lower box bottom are respectively provided with blower fan and mate with blower fan.
The fixing cooling grate plate of described integral body is comprised of grate plate, the whole fixing stepped case top that is arranged on of cooling grate plate.
Described lower box is comprised of the left case of lower box and the right case of lower box.
The blower fan arranging in described upper box and middle casing is centrifugal fan, and the blower fan arranging in lower box is roots blower.
Useful good effect of the present utility model:
1, the utility model adopts four box cooling chamber structures to guarantee that high temperature chamotte wind area is large, and wind-engaging is even, and clinker cooling is abundant, and cooling velocity is fast.
2, the utility model adopts whole fixing cooling grate plate, guarantees that high temperature chamotte does not leak material in moving process.
3, the whole fixing cooling grate plate of the utility model is ladder-like arranged, and the transfer efficiency of grog is improved, and has reduced SR, effectively the service life of extension device.
4, because the high temperature chamotte bed of material on the cooling wallboard of casing is the thickest, adopt roots blower air feed, both reduced the pressure loss, also guaranteed that high temperature chamotte wind-engaging is even, unit are wind-force is maximum, and grog is cooling fast.
Accompanying drawing explanation
Fig. 1 is cutaway view of the present utility model;
Fig. 2 is the top view of this Fig. 1 wallboard.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the meaning of number in the figure representative is: 1. charging aperture, 2. grate plate, 3. whole fixing cooling grate plate, 4. upper box, 5. wallboards of box body, 6. in casing, 7. lower box, 8. roots blower, 9. centrifugal blower, 10. centrifugal blower, 11. housings, the left case of 12. lower box, the right case of 13. lower box, 14. air inlets, 15. air inlets, 16. air inlets.
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.
Shown in Fig. 1 and Fig. 2: a kind of grate-cooler one Room cooling structure, comprise housing 11 and whole fixing cooling grate plate 3, whole fixing cooling grate plate 3 guarantees that grog does not leak material.Described housing 11 one end are provided with charging aperture 1, housing 11 inside are provided with wallboard 5, described wallboard 5 is divided into upper box 4, middle casing 6 and lower box 7 by housing 11, lower box 7 is comprised of the left case 12 of lower box and the right case 13 of lower box, adopt four box cooling chamber structures to guarantee that high temperature chamotte wind-engaging is even, clinker cooling is abundant, and cooling velocity is fast.The air inlet 14,15 and 16 that described upper box 4, middle casing 6 and lower box 7 bottoms are respectively provided with blower fan and mate with blower fan, interior centrifugal fan 9 and 10 of being provided with respectively of upper box 4 and middle casing 6.The blower fan of lower box 7 interior settings is roots blower 8, has guaranteed that high temperature chamotte wind-engaging is even, and unit are wind-force is maximum, and grog is cooling fast.The fixing cooling grate plate 3 of described integral body is comprised of grate plate 2, stepped housing 11 tops that are arranged on of whole fixing cooling grate plate 3.
The course of work of the present utility model is:
Hot grog unloads and drops on whole fixing cooling grate plate 3 from charging aperture 1, along fixing cooling grate plate 3 total lengths of integral body, be distributed, form the bed of material of certain thickness, because the fixing cooling grate plate 3 of integral body is high near charging aperture 1 end position, low near grate-cooler one Room end end position, grog is moved to low side by high-end because of deadweight, finally from grate-cooler one Room end, enters next chamber.Cooling air is blown into diffusion in the bed of material from grate plate 2 belows, to grog, carries out cooling.First to grog carry out air feed cooling be the centrifugal blower 10 of upper box 4, be secondly the centrifugal blower 10 of middle casing 6, be finally the roots blower 8 of lower box 7.Because the fixing cooling grate plate 3 of integral body is skewed layout, high temperature chamotte is because oneself focuses in moving process, and the bed of material became uneven of hot grog diverse location in grate plate 2 is not identical to the resistance of cooling air yet.Wherein above upper box 4, the bed of material is the thinnest, resistance to cooling air is also less, the bed of material above lower box 7 is the thickest, also maximum to the resistance of cooling air, therefore at upper box 4, select the centrifugal blower 10 that power is relatively little, at middle casing 6, select the centrifugal blower 9 that power is relatively large, at lower box 7, select roots blower 8.
