Oil storage tank with double-layer structure

Abstract

The invention discloses an oil storage tank with a double-layer structure. The oil storage tank comprises an oil storage tank body and a control module, the oil storage tank body comprises an outer wall, a manhole is formed in one side of the bottom of the outer wall, a displayer is arranged above the manhole, an oil outlet pipe is arranged on the other side of the bottom of the outer wall, a warning light is arranged on the upper portion of the oil outlet pipe, an oil inlet pipe is arranged on one side of the top of the outer wall, a filter screen is arranged at the bottom of the oil inlet pipe, a fire barrier is arranged on the other side of the top of the outer wall, a breather valve is arranged on the top of the fire barrier in a penetrating mode, an electromagnetic heating layer is arranged on the inner side of the outer wall, an insulating layer is arranged on the inner side of the electromagnetic heating layer, and the inner wall is arranged on the inner side of the insulating layer. The oil storage tank has the advantages that design is reasonable, the structure is simple, oil product stratification problem in the oil storage tank is effectively solved, and then the sales volume is effectively guaranteed; meanwhile, the processing charges of oil products are effectively lowered, and then the cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of storage, in particular to an oil storage tank with a double-layer structure. Background technique [0002] It is known that oil blending is to test the product characteristics of various petroleum fractions. According to product characteristics such as: density, cetane number, octane number, fraction temperature, viscosity, impurity content, etc., according to the above indicators, according to the national standard Blend oil products according to the national standard fuel oil at the lowest cost. Chemical additives (mainly liquid fuels) and various waste oils (waste engine oil, tire oil, plastic oil, etc.) need to be added to the national standard or It is non-standard blending, which can satisfy the use of imported cars, domestic cars, high-speed engines, low-speed engines, etc. Finally, the blended finished oil products are stored in oil storage tanks; however, during the storage of finished oil produc...

[0002] It is known that oil blending is to test the product characteristics of various petroleum fractions. According to product characteristics such as: density, cetane number, octane number, fraction temperature, viscosity, impurity content, etc., according to the above indicators, according to the national standard Blend oil products according to the national standard fuel oil at the lowest cost. Chemical additives (mainly liquid fuels) and various waste oils (waste engine oil, tire oil, plastic oil, etc.) need to be added to the national standard or It is non-standard blending, which can satisfy the use of imported cars, domestic cars, high-speed engines, low-speed engines, etc. Finally, the blended finished oil products are stored in oil storage tanks; however, during the storage of finished oil products, due to the addition of Due to different density or long-term storage, the upper, middle and lower layers of oil in the oil storage tank are prone to stratification, resulting in different oil quality in each layer, which greatly affects its sales.

The current practice is to achieve the required oil quality through compounding process, which not only complicates the process, but also greatly increases the processing cost of the oil

[0003] For the problems in related technologies, no effective solutions have been proposed yet
