Terminal bulk cement pneumatic unloader
? With the development of the market economy, the unloading task of bulk materials at Jianghu Wharf is very busy. There is a great demand for pneumatic unloaders for bulk cement for 1000t ships in the Pearl River Delta of Guangdong Province. Difficult to deliver materials such as ore and coalPneumatic unloaderTo be researched and developed.
? Yueyang Port Bulk Cement Pneumatic Unloader System. It is suitable for unloading about 1000 bulk cement ships in Rivers and Lakes. The system consists of two parts.
? One is to transport the cement bulk from the cement bulk ship to the cement intermediate material tower, using an extendable rotary pneumatic unloader,
? The second method is to transport the intermediate material from the cement tower to the cement silo, using two jet pumps for exchange and transportation.
? ?Its structure is that the suction nozzle and feeding pipe are installed on the hanger, and the droop switch of the suction nozzle and the pitch and rotation of the hanger are controlled in the operating room, which can achieve suction at different positions. After the cement is separated by the first stage cyclone separator, it is discharged through the discharge valve, and the dusty air is discharged to the atmosphere through the bag filter. The designed conveying capacity of the device is 100/h, with a horizontal distance of about 10m and a vertical lifting height of about 22m. It uses a three blade Roots blower with a driving power of 150kW. The pressure conveying system from the intermediate material tower to the cement silo adopts two jet pumps for exchange and transmission, basically achieving continuous conveying. Main technical parameters: designed conveying capacity of 100 hours, conveying horizontal distance of about 150 meters, vertical lifting height of about 50 meters (designed with high water level during dry season), jet pump volume of 6 square meters, air source pressure greater than or equal to 0.7 MPa, conveying pressure of 0.2~0.35 MPa, conveying diameter of 159x7mm seamless steel pipe, designed material gas mixture concentration ratio greater than or equal to 50.
