Description

Technical Field

[0001] The utility model relates to the technical field of cleaning pipelines of a cobalt powder roasting furnace, in particular to an automatic cleaning device for cleaning pipelines of a cobalt powder roasting furnace. Background Art

[0002] During the preparation of cobalt oxide, a certain concentration of HCl and 140g / L of cobalt compounds will be produced. During the preparation process, the proportion of HCl will gradually increase, and when it reaches saturation, the dissolution will stop. In order to keep the dissolution process going, the cobalt oxide in the HCl should be extracted, and the acid concentration should be reduced at the same time. A set of preparation processes and equipment is required to send the HCl solution containing the above proportion to the preparation device to generate cobalt tetroxide, and at the same time, hydrochloric acid with a concentration of about 15% is obtained, and then returned to the dissolution system to reuse the waste acid liquid. The process is: the cobalt oxide solution containing a certain proportion of concentration and content is collected in the waste acid tank, and sent to the pre-concentrator through the waste acid filter by a waste acid pump, and the flow rate is automatically controlled by a pneumatically adjusted valve. The waste acid is pumped to the top of the pre-concentrator through the pre-concentrator circulation pump for spraying. Direct heat exchange is carried out with the furnace gas (400°C) from the roasting furnace to evaporate part of the water in the waste acid, and the waste acid liquid is concentrated. The concentrated waste acid liquid is sent to the top of the roaster by the roaster feed pump through the roaster feed pipeline, and then sprayed into the roaster through the spray rod and nozzle.

[0003] The existing roasting furnace feed pipeline will form crystals on the pipe wall during operation, and must be cleaned regularly. At present, this pipeline cleaning and maintenance work is very difficult and labor-intensive. The furnace must be shut down first, the pipeline must be disassembled and cleaned manually with a cleaning agent, and then the pipeline must be installed and the furnace restarted after cleaning. This pipeline cleaning and maintenance work is time-consuming, material-consuming, and will pollute the environment. Therefore, it must be improved.
