Description

Technical Field

[0001] The utility model relates to the technical field of waste mineral oil, in particular to a waste mineral oil transfer box. Background Art

[0002] Waste mineral oil refers to mineral oil extracted and refined from petroleum, coal, and oil shale. During the mining, processing, and use process, the original physical and chemical properties have changed due to external factors and cannot be used any longer. Waste mineral oil is a type of hazardous waste and needs to be stored in a centralized and isolated manner.

[0003] The waste mineral oil temporary storage tank is a commonly used temporary centralized storage place for waste mineral oil. To ensure safety, the waste mineral oil in the waste mineral oil temporary storage tank needs to be transferred to a specific container in time. During the transfer of the waste mineral oil, a forklift is needed to place the waste mineral oil barrel together with the pallet for placing the waste mineral oil barrel in a transfer box. However, the existing transfer box lacks a device for fixing the pallet and the waste mineral oil barrel, which causes the pallet and the waste mineral oil barrel to slide relative to each other during the transfer process, causing the waste mineral oil barrel to fall over. In this regard, a Chinese patent with publication number CN218173001U discloses a waste mineral oil transfer box, in which a pallet is fixedly connected to the lower side of the inner wall of the box, and a pallet is placed on the upper end of the pallet to fix the waste mineral oil barrel.
