Heat generated by the hot air into the wood chip dryer cylinder, the cylinder body wall first, leaf axis or feed plate metal preheating, sawdust from sawdust dryer feed into the mouth, inside the wood chip dryer materials the blade shaft or feed plate raise or the rotation of the drum itself float in the sky, and then material, blade shaft and cylinder or feed plate and other metal intimate contact, using hot air separation of moisture away dry material.The material is discharged from the sawdust dryer outlet or from the bottom of the configured shakron, and the hot and humid gas and smoke are removed from the top of the shakron.The material mainly depends on the center of the blade shaft or the uplift role of the plate, or the sawdust dryer has a tendency to Angle of operation.

Ethylene plant methane refrigeration compressor is one of the major projects of Zhongyuan Petrochemical overhaul. As the highest speed of the whole factory imported from Germany, its rotational speed is up to 45,633 rpm, the equipment structure is complex, the maintenance procedures are cumbersome, and the technical requirements are particularly high. After receiving the inspection task, the workshop translated the English data of the equipment in advance, set up an inspection team headed by the workshop leader, went deep into the site, discussed the preparation of the maintenance program, and carefully drafted the inspection kanban, which was performed on every node of the inspection. Careful deployment.
Because it was the first time overhaul, everyone did not dare to slack off. Every day, as soon as they went to work, everyone put on work clothes early to discuss the progress of the day's work and work arrangements. Leaders of the workshop sit in command and solve problems in as short a time as possible. The entire overhaul was conducted in the open air and the environment was unbearable. The weather in June was hot and the maximum temperature was 36 degrees. It is one day to work at this high temperature. This is undoubtedly a test of physical strength and perseverance. After a while, everyone's clothes were soaked in sweat. Everyone was faced with sweat and mud. Maintenance staff is relying on this kind of selfless work spirit, concentrating on efforts to overcome various difficulties and strictly follow the maintenance procedures. During this inspection and repair process, it was found that the compressor impeller has been significantly worn out. After extensive discussion and research, a feasible maintenance method was determined, which provided a powerful guarantee for the long-term operation in the future. The maintenance work was carried out in a busy and unstructured manner. At the end of the inspection work, an unexpected situation occurred: after the seals were installed by dry gas seal manufacturers, they were carefully inspected by maintenance personnel and found major hidden dangers. They were promptly proposed and repositioned the seals to prevent the accidents of driving. occur. This also highlights the work style based on me, not blindly trusting experts, and the ownership of their own equipment must be their own responsibility.
After the joint efforts of the cadres and workers in the machine repair shop, the overhaul task of Zhongyuan Petrochemical's ethylene plant for methane refrigeration compressors was successfully completed on June 30. This marked the completion of the maintenance of the large unit of the ethylene workshop.
