Description

Technical Field

[0001] The invention relates to the technical field of oil tank cleaning equipment, in particular to a multifunctional tank bottom oil cleaning machine. Background Art

[0002] Oil storage tanks, referred to as oil tanks or storage tanks, are large containers with regular shapes used to store oil products, often made into cylindrical structures. The tank body consists of three parts: the top cover, the wall plate and the bottom plate. It is generally used to store heavy oil products. This type of oil tank has the advantages of saving steel, good durability, low maintenance costs and low oil loss, but there are more construction processes and a longer cycle. Semi-underground or underground reinforced concrete oil tanks also have the advantages of good fire resistance, small tank spacing, and small wall temperature difference. When the capacity of the oil tank is large, prestressed concrete oil tanks are often used to apply circumferential prestress. For oil tanks storing edible vegetable oils, especially soybean oil and rapeseed oil crude oil, more and thicker oil feet will form on the bottom after two years of storage, and these oil feet are difficult to clean.

[0003] When edible vegetable oil in some existing oil tanks is removed from the warehouse, the accumulated oil residue at the bottom is usually cleaned and collected manually. The tools needed for manual cleaning are mainly shovels, brooms, scrapers, oil drums, shovels, rags, etc., and the working environment in the tank is poor, which not only consumes more manpower and material resources, but also has low cleaning efficiency, and the broom blades are easy to fall into the grease, affecting the recovery quality of the grease. Summary of the invention
