Abstract
The utility model relates to a kind of shaft cooler air-cooled grate plate brace summer.Grate plate is had in shaft cooler, grate plate is supported by grate plate brace summer, grate plate brace summer is tubing, one end seals with air inlet pipeline and communicates, the other end seals with air outlet pipeline and communicates, described air inlet pipeline seals with kiln hood cooling air system and communicates, and described air outlet pipeline enters rotary kiln head-shield, participates in kiln combustion.Its structure is simple, long service life.
Description
Technical field
The utility model relates to one and belongs to metallurgical engineering field, particularly relates to the brace summer of the air-cooled grate plate of a kind of shaft cooler.
Background technology
The effect of producing the shaft cooler grate plate of active lime clears out the bulk material of improper production status and the kliner coating of ring formation of rotary kiln generation, ensures that shaft cooler feed opening is unobstructed.Grate plate is pressed on three grate plate brace summers, and grate plate and grate plate brace summer are subject to transmission of heat by contact and the heat radiation of the about 1000 DEG C of lime fallen in rotary kiln, and operating temperature is usually more than 900 DEG C; Grate plate brace summer is about 3.2 meters (for LSF-4.7 × 8.9 shaft coolers), and bear the impact constantly falling material in the Action of Gravity Field of grate plate (about 3.1 tons) and rotary kiln, often there is the situation that flexural deformation and damage are scrapped in grate plate brace summer production process.
In view of the special operation condition of grate plate brace summer, generally use casting heat resistant steel, material often gets ZG30Cr20Ni10 (serviceability temperature 900 DEG C), and for ensureing bulk strength, also can require the casting of whole of grate plate brace summer, does not allow welding.However, still there is the diastrophic situation of grate plate brace summer in actual production, not only made the grate plate of expensive heat resisting steel manufacture and grate plate brace summer scrap, and needed long-time stop production to overhaul, cause very large production loss.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of shaft cooler air-cooled grate plate brace summer, and its structure is simple, long service life.
The technical scheme in the invention for solving the technical problem is: have grate plate in shaft cooler, grate plate is supported by grate plate brace summer, grate plate brace summer is tubing, one end seals with air inlet pipeline and communicates, the other end seals with air outlet pipeline and communicates, described air inlet pipeline seals with kiln hood cooling air system and communicates, and described air outlet pipeline enters rotary kiln head-shield, participates in kiln combustion.
The utility model has following advantages: 1), adopt heavy wall tubular structure, is conducive to improving bearing capacity under equivalent weight; 2), adopt the casting heat resistant steel of ZG35Cr28Ni16, heat resisting temperature can reach 1150 DEG C, and heat resistance is good, carrying and strong shock resistance under high temperature; 3), long service life.By ventilating and cooling, take away the inner surface heat of grate plate brace summer in time, obviously can reduce the operating temperature of grate plate brace summer, operating temperature reduces then its bearing capacity and significantly improves; 4) utilize rotary kiln end cooling air system, draw bypass and blast cold wind, save the cost of joining separately cooling air system; 5), to grate plate brace summer carry out cooled hot blast and enter participation burning in rotary kiln by kiln head cover, effectively utilize heat energy.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model schematic diagram;
Fig. 2 be in the utility model Fig. 1 A to figure.
Detailed description of the invention
As shown in Figure 1, 2, grate plate 2 is had in shaft cooler 3, grate plate 2 is supported by three grate plate brace summers 1, three grate plate brace summers 1 are all tubing, one end of three grate plate brace summers 1 seals with air inlet pipeline 4 simultaneously and communicates, and the other end seals with air outlet pipeline 6 simultaneously and communicates, and described air inlet pipeline 4 seals with kiln hood cooling air system 5 and communicates, described air outlet pipeline 6 enters rotary kiln head-shield, participates in kiln combustion.
The material of described grate plate brace summer 1 is ZG35Cr28Ni16, and serviceability temperature can reach 1150 DEG C.
Cooling air, by after three grate plate brace summers 1, pools together through air outlet pipeline 6 and enters rotary kiln end cover, finally participates in kiln combustion.The present invention utilizes rotary kiln end cooling air system 5 to draw bypass and blasts cold wind and constantly carry out ventilating and cooling to grate plate brace summer 1 hollow space, the operating temperature of grate plate brace summer 1 can be reduced, cooled hot blast is carried out to grate plate brace summer 1 and enters participation burning in rotary kiln by kiln head cover.
Claims (2)
