Buried oil unloading well

Abstract

The invention discloses a buried oil unloading well. The buried oil unloading well comprises a base, a close-up support, a frame connecting part, a well frame and a well lid. The base, the close-up support, the frame connecting part, the well frame and the well lid are sequentially connected to form a cavity. An oil unloading pipeline and an oil storage basin are arranged in the cavity, an oil unloading ball valve is arranged at the position of an inlet of the oil unloading pipeline, and the other end of the oil unloading pipeline penetrates through the base to communicate with an oil storagedevice. The oil unloading pipeline penetrates through the oil storage basin in a sealed manner, the oil storage basin is mounted on the lower portion of the oil unloading ball valve, and an oil overflow backflow device is arranged between the oil storage basin and the oil unloading pipeline. The buried oil unloading well system is mounted below a terrace, the area of land is not occupied, and theburied oil unloading well is suitable for small filling stations in cities. Through the arrangement of the oil storage basin and the oil overflow backflow device, residual oil dripped and scattered during oil unloading can be collected in a centralized manner and recharged in time, waste of overflow oil is avoided, and potential safety hazards caused when the oil volatilizes to form accumulated oil gas are avoided.

Description

technical field [0001] The invention relates to a buried oil unloading well, which belongs to the technical field of gas station equipment. Background technique [0002] Along with the economic development, the rapid development of the domestic automobile industry has promoted the development of the transportation industry, and also made the number of gas stations all over the country increase greatly in recent years. However, in urban areas where land resources are scarce, with the increase of land cost and construction cost, the miniaturization of gas stations in the city is an important development direction in the future. Generally, the oil unloading port of existing gas stations is located on the ground of the oil tank area, with a height of about half a meter. An additional steel unloading tank or brick oil unloading room needs to be installed outside the oil unloading port to protect the valve of the oil unloading port and Pipeline, which will occupy part of the land...

AI Technical Summary

Problems solved by technology

Generally, the oil unloading port of existing gas stations is located on the ground of the oil tank area, with a height of about half a meter. An additional steel unloading tank or brick oil unloading room needs to be installed outside the oil unloading port to protect the valve of the oil unloading port and Pipeline, which will occupy a part of the land area, which is extremely unfavorable for the construction of small gas stations in the city, so it is necessary to install buried oil unloading wells to reduce the area occupied by the unloading area and construction costs
