Description
Technical Field
The utility model belongs to the technical field of the car oil discharge technique and specifically relates to an unification buffer for airtight loading and unloading operation.
Background
The crude oil collected from the petroleum production operation area is simply processed on the spot according to the difference of the output of the operation area, collected to a centralized loading and unloading point such as a loading station, an oil filling and water injection station, a combined station and the like in a pipeline transportation or land transportation mode, temporarily stored, and transferred to an oil refining enterprise for deep processing through a relatively centralized way after reaching a certain storage capacity. Because the distance between each oil extraction point is relatively far away in China, the oil output of each point is not large, the condition that crude oil is conveyed by adopting a pipe conveying mode is less, the crude oil extracted by each single-well oil extraction point needs to be conveyed to a unified united station through an automobile tanker for transportation, and the condition is common.
The oil tank truck transports the crude oil to a centralized combination station and then needs to discharge the crude oil to a designated transfer tank, the current general mode is that a plurality of crude oil transfer tanks are built in the combination station, the oil discharge process of the current combination station is as shown in figure 1, after the oil tank truck stops at an oil discharge platform, a hose is connected with an oil tank truck discharge port, then a valve is opened, the crude oil is discharged to the transfer tanks through gravity, and then is conveyed to an oil storage tank or a settling tank through a pump on an oil discharge pipeline, wherein the transfer tanks are barrel-shaped, the transfer tanks are vertically placed on a support, the oil tank truck is connected with the transfer tanks through oil discharge pipes, the bottom of the transfer tanks is connected with oil discharge pipes, and the oil in the transfer tanks is conveyed to the oil; however, the prior oil unloading device has the following disadvantages in use:
1. when the oil is discharged in a closed manner, the oil in the oil tank truck is discharged to the adapter tank through gravity, and because the adapter tank is in a sealed state, gas is not discharged in the oil discharging process, so that gas resistance is formed, the adapter tank is vertically placed on the bracket, so that when the oil is pumped to the end, the oil pumped to the last oil tank truck cannot be pumped completely because the height of the bottom of the oil tank truck is higher than the height of an oil inlet on the adapter tank and the gas in the adapter tank is combined, and the pressure in the adapter tank is higher than that in the oil tank;
2. the oil discharge pipe is heavy, at present, the oil discharge pipe can be hung on the ground to dirty the oil discharge pipe under the state of not discharging oil, two people are needed to lift the oil discharge pipe when discharging oil again, and the lifting is laborious.
Therefore, the structure of the adapter tank needs to be redesigned, and a combined buffer device for airtight loading and unloading operation, which can unload the oil in the oil tank truck cleanly, is designed.
SUMMERY OF THE UTILITY MODEL
