Description

Technical Field

[0001] The utility model relates to the technical field of purification equipment, in particular to a crude oil tank bottom mud sand purification device. Background Art

[0002] Oil storage tanks, referred to as oil tanks or storage tanks, are large containers with regular shapes used to store oil. They play an important role in oil depots that need to be transferred and in oil source interfaces of oil pipelines in pipeline transportation. They can be divided into metal oil tanks and non-metallic oil tanks according to different construction materials. Most metal oil tanks are steel oil tanks, which are widely used due to their low cost, low leakage, convenient construction and easy maintenance. After long-term use, there is a large amount of tank bottom sludge at the bottom of the oil tank. The tank bottom sludge mainly comes from the oily sludge generated during oil field production and gathering and transportation. It has strong viscosity and is very difficult to remove. In order to reuse the oil barrels, crude oil tank bottom mud sand purification equipment is needed to clean the sludge mixture.

[0003] Chinese utility model disclosure specification CN220005294U discloses an oil tank sludge removal component, which drives the movement of a U-shaped cleaning brush by raising and lowering a serrated column through a control box. The operation of a rotary motor drives the rotation of the U-shaped cleaning brush, making it more convenient to clean the inside of the oil tank, saving time and effort while reducing the labor intensity of workers. A valve arranged at the top facilitates both the control of the water volume and the flushing of the oil tank by a connected nozzle.

[0004] In summary, due to the strong viscosity of oily sludge, some mud and sand will get stuck between the bristles of the U-shaped cleaning brush when used, and it is not easy to fall off, which affects the cleaning effect and service life of the U-shaped cleaning brush. Utility Model Content
