Yanhua melt blown cloth project equipment is installed in place and enters trial production

2020-03-13
China Petrochemical News Network News Yanshan Petrochemical's new melt blown cloth production line project is progressing smoothly. During the installation of the equipment, a three-dimensional crossover work network was formed on the project site. All the construction staff actively benchmarked the construction speed of Huoshenshan and Leishenshan Hospitals, and every second counts and pays close attention to the progress. After 5 days and 5 nights of hard work, as of 3:30 am on March 5th, the net forming machine, electret machine, slitting machine, winder and other large key equipment that arrived at the end have been installed in place. The project Started to enter the trial production stage.

On February 29, the main plant equipment foundation of the Yanshan Petrochemical Meltblown Cloth Production Line Project was completed, and the project construction began to transfer to the equipment installation stage, and the battle for large-scale key equipment installation began.

The first installation is the steel structure, process piping and high and low voltage switch cabinets. At around midnight on the 29th, the hoisting operation of the 7 columns and steel beams of the main equipment frame and the installation of the operating platform began. After nearly 6 hours of hoisting construction, the columns and steel beams were hoisted and installed in place, and the steel structure assembly of the operating platform was basically completed by noon on March 1. Starting at noon, the construction crew worked together again, hoisting the 4 main fans into place.

At 0:30 midnight on March 2nd, Yanshan Petrochemical's new meltblown non-woven fabric production line project site roared and bright as daylight. The 450-ton crawler crane uses a long boom to hoist a melt-blown steel lifting platform with a length of 7.2 meters and a width of 4.5 meters to a high altitude, and transport it to the base frame of the plant through the gap in the roof of the plant. At 3:30, the lifting platform was installed in place. By 11 noon on March 3, two screw extruders were installed in place. Immediately afterwards, important equipment such as the automatic feeding metering and mixing system, the feeder and the meltblown die head will be installed one after another, and the core equipment of the meltblown non-woven fabric production line will be revealed one after another.

At 16:00 pm on March 3, 3 large transport vehicles carrying 2 netting machines, 2 offline winding machines, and 2 offline slitting machines, which lasted 29 hours and traveled 1,350 kilometers, arrived from Changzhou, Jiangsu Construction site. The hoisting work of these large-scale key equipment, known as the "three major pieces" of post-processing, immediately began, and another arduous encounter in the equipment installation stage started again.

At 22:00 on the evening of March 3, the first net-forming machine was unloaded and transported into the plant. Due to the large size of the net-forming machine, which weighs 8.62 tons, the ground hardness of the backfill part in the workshop is not high, which causes the forklift to sink and tilt forward during the unloading process, which causes great difficulties for the unloading. After urgent discussion and confirmation, Yanhua Company adjusted the unloading plan in time and decided to use two cranes to hoist the net-forming machine to the designated position.

At 3 o'clock in the morning on March 4, the hoisting of the net forming machine began. With the hard work of the combat personnel on the scene, the behemoth was hoisted and adjusted in place until 8 am. Subsequently, another netting machine was also hoisted in place.

At 19:00 on March 4, the last two equipment of the melt blown cloth production line, the electret processor, took 29 hours to be transported from Nantong, Jiangsu to the site of the Yanshan Petrochemical melt blown cloth project.

At 21:30 on the evening of March 4, large-scale key equipment such as electrets, slitting machines, and winding machines gathered at the site to begin lifting operations in sequence. After an all-night battle, all equipment was in place by 3:30 in the morning. At the same time, the exhaust pipes of the two induced draft fans have also been installed.

At 8:30 a.m. on March 5th, a test run of the fan began. So far, Yanshan Petrochemical's new melt blown cloth production line project has begun to enter the trial production stage, and it is just around the corner before it is completed and put into production.
