Description

Technical Field

[0001] The utility model relates to the technical field of lead grid cleaning and drying, in particular to a lead grid cleaning and drying device. Background Art

[0002] In the complete set of equipment for crushing and separating waste lead-acid batteries, the lead grid passes through the cleaning spiral and then enters the drying kiln through the spiral conveying fan blades. The broken lead grid after coming out of the drying kiln enters the low-temperature melting pot for ingot casting. However, with the production increase and transformation of the complete set of equipment for crushing and separating waste lead-acid batteries, the output of broken lead grids has increased, and the original cleaning spiral and drying kiln cannot meet the production needs, resulting in insufficient cleanliness of the lead grid and increased water content of the broken lead grid coming out of the drying kiln. When the broken lead grid enters the melting pot, the impurity content in the lead pot will increase, and it will require additional processes to extract metals from the impurities, which will lead to a decrease in production efficiency. In order to cope with the production increase of the waste lead-acid battery crushing and separation system, it is necessary to find a device that can effectively clean and dry the lead grid.
