Abstract
The utility model relates to the technical field of the preparation of cobaltosic oxide and the recovery of hydrochloric acid, in particular to a feeding pipeline online cleaning device of a roasting furnace for preparing cobaltosic oxide powder. A circulation online cleaning system is formed by a cleaning agent circulation tank, a feeding device and a fresh water pipeline which are connected with a roasting furnace feeding pipeline, and a cleaning liquid reflux pipeline which is connected between the end of the roasting furnace feeding pipeline and the cleaning agent circulation tank. The feeding device is a feeding pump which is connected with a waste acid tank or a pneumatic feeding device that consists of a compressed-air inlet pipe, an air filter and an air feed valve that are connected with the waste acid tank. The feeding pipeline online cleaning device has the advantages that the online cleaning to the roasting furnace feeding pipeline can be carried out momentarily, the pipeline needs not to be disassembled and installed again when the feeding pipeline is cleaned, thereby not only improving the equipment utilization rate of the roasting furnace effectively, but also reducing the workload of pipeline cleaning and maintenance and the maintenance cost, and also not generating the pollution to environment.
