15 , the cement kiln of Huangping Jianfeng Cement Company resumed feeding production.
Before this production, the preheater system of Huang Ping Peak Cement Kiln replaced two air lock valves. In order to prevent the new air lock valves from flashing and inflexible at the initial stage of production, the manufacturing department deployed forces to assist before feeding.00:08 Feeding, on-site reaction all levels of air lock valves are operating normally. After confirming that the materials have entered the kiln and fired into the belt, the manufacturing department will arrange the personnel at all levels to assist the shaking of the air lock valve to begin to evacuate.
However, at00:45 , the on-site reaction C5A lower lock air valve was stuck. After inspection, it was found that a whole piece of crust on the blanking pipe was across the spreader, thus causing the jam to stop. Although the site immediately organized personnel to clean up, but because the crust is too hard, can not successfully complete the cleaning work.
After the handover of the two shifts at8 in the morning, after determining the working environment and cleaning operation characteristics on site, the on-site post workers started the cleaning work and cleaned up step by step from the material scattering table. The post personnel first use steel drill to make a through hole in the material at the opening of the blanking pipe, and make sure that the material can flow downward without being sprayed out from the opening with the help of the pumping force of the wind, and then clean it with a high-pressure water gun. After cleaning for a period of time, the original hole was temporarily closed, and another hole was opened above. After repeated, the cleaning was finally completed at 4 in the afternoon. The clearing of the discharge pipe ensures the multi-point characteristics of the materials entering the decomposition furnace and the pre-pouring of the materials entering the kiln, ensures the stability of the temperature field of the decomposition furnace body, and provides the basis for the kiln to increase production.
