Description

Technical Field

[0001] The utility model relates to the technical field of processing devices for barreled biodiesel production raw materials, in particular to an automatic barrel cover discharge device for barreled waste grease. Background Art

[0002] Currently, biodiesel production generally uses waste oils such as gutter oil and sewage slop as its primary raw materials. While most of this waste oil is transported by tank trucks, a small portion is packaged and transported in 200-liter iron drums. In industrial production, barreled waste oil must first be sampled and analyzed, and only barreled oil that meets quality requirements is poured into the production line. Currently, barrel-breaking machines are commonly used to completely cut the thin steel cover of the iron barrel along the edge to complete the process. After the barrel is broken, the cover that falls below the surface of the waste oil must be manually removed. After the cover is removed, the barrel is then sent to the barrel-depositing machine to complete the deposit. However, there are several drawbacks: First, the sharp edges of the thin steel cover cut during the barrel-breaking process can easily cause cuts to the operator's hands when manually removing the cut cover, even when wearing gloves, posing a safety hazard. Second, manual removal of the cover that falls below the surface of the waste oil is slow, resulting in low efficiency. Summary of the Invention
