Grate cooler is an important host equipment in clinker firing system of cement plant its main function is to cool and transport cement clinker and to provide hot air for rotary kiln and calciner which is the main equipment of heat recovery in firing system.
The high temperature clinker is unloaded from the kiln mouth to the grate bed, and under the reciprocating push of the grate plate, the high temperature clinker is distributed along the full length of the grate bed to form a material bed with a certain thickness. The cooling air blows into the material layer from under the material bed, permeates and diffuses, and cools the hot clinker. The cooling air after cooling clinker becomes hot air, high temperature hot air is used as combustion air into kiln and decomposition furnace (precalciner kiln system), some hot air can also be used for drying, and excess hot air will be discharged into the atmosphere after dust collection.
1.Grate cooler is an important host equipment in clinker firing system of cement plant its main function is to cool and transport cement clinker and to provide hot air for rotary kiln and calciner which is the main equipment of heat recovery in firing system.
2.Different grate plate configuration and controllable fine air supply in different units and areas make the distribution of cooling air more uniform and effectively eliminate the phenomenon of "Red River".
3.The utility model has the advantages of high cooling efficiency low clinker temperature and good quality and has strong adaptability to clinker and firing conditions (including granulation output etc.).
4.The heat recovery effect is good on the basis of providing high and stable secondary and tertiary air reliable waste heat power generation and drying air can be provided according to the need and the exhaust gas temperature of the kiln head dust collector is low.
5.The meticulously designed large stiffness structure makes the gap of the grate bed uniform the ability to resist abnormal conditions (such as falling kiln skin laying eggs etc.) is greatly enhanced and the occurrence of press bed is avoided.
6.The key important elements of high quality and large abundance of selection or design so that the reliability of the equipment is greatly improved.
7.The special structural type of anti-wear grate plate and streamline labyrinth grate joint not only has uniform air outlet and good air permeability but also has less material leakage less wear and long life of the grate bed.
8.based on the humanized thinking of users the operation inspection and maintenance of equipment are simple and convenient and the cost is low.
9.The operation rate is high and the production will not be affected by the problem of the cooler.
The fourth generation LSFC push system rod grate cooler:
1.Modular design according to the need to facilitate the composition of different sizes of coolers high manufacturing accuracy short cycle convenient installation and maintenance.
2.Using row grate bed each row of grate plate can adjust speed independently which has good adaptability to clinker distribution.
3.The use of automatic flow control valve and more detailed zone air supply to prevent short circuit of cooling air and ensure stable air distribution.
4.The standard grate plate is covered with static clinker layer to protect it from high temperature and wear and the grate plate no longer needs to be replaced regularly.
5.Special types of leak-free grate plates and non-contact seals ensure no leakage and can save ash hoppers and conveying systems.
6.The movable grate bed is completely horizontal coupled with the ash-free bucket the height of the whole machine is greatly reduced and the investment in civil construction can be greatly saved.
7.The special sealing structure between each row of grate plates the seals are easy to adjust install and disassemble do not need to empty the static material layer on the grate plate and the maintenance is convenient.
