Abstract

The invention relates to an oil tank and a method for checking and maintaining a rotary ejector in the oil tank, the oil tank comprises a tank body, the rotary ejector, a base and a traction piece, the first end of the traction piece is detachably connected with the rotary ejector, the second end of the traction piece penetrates through an opening of the tank body to be exposed out of the tank body, and a liquid inlet is formed in the tank body; the liquid inlet is communicated with an inlet of the rotary ejector, the base is fixed to the bottom of the tank body, and the rotary ejector is arranged on the base in a pluggable mode. When the rotary ejector needs to be overhauled, the second end, exposed out of the opening of the tank body, of the traction piece is pulled, the rotary ejector is lifted to the opening of the tank body to be taken out, and then the rotary ejector is overhauled. And after overhauling is completed, the rotary ejector is lowered to the base through the traction piece. According to the oil tank, on-line inspection and maintenance of the rotary ejector in the tank can be achieved, tank cleaning operation during existing inspection and maintenance and the process that an operator enters the tank are avoided, and the safety risk of inspection and maintenance is greatly reduced.

Description

technical field [0001] The present disclosure relates to the technical field of petroleum storage equipment, in particular to an oil tank and a method for checking and maintaining a rotary injector in the oil tank. Background technique [0002] The composition of crude oil stored by petrochemical enterprises varies from place to place. After the oil enters the storage tank, the condensable substances in it settle at the bottom of the tank to form sludge. If sludge deposits, it will cause oil loss, reduction of effective volume of storage tank and many other problems. With the increase of sediment, the storage tank needs to be cleaned regularly, and a large amount of sediment will also cause many problems such as difficulty in maintenance and cleaning of the storage tank, pollution of the environment, and increase in oil loss. Therefore, the oil storage tank is equipped with a rotating jet, which regularly stirs the oil in the tank to make the medium in the tank uniform and...
