Embodiment Construction

[0015] A barrier and explosion-proof underground oil storage tank that can be cleaned and maintained. It has a measuring pipe 2, an oil inlet pipe 3, an oil outlet pipe, a check valve or an oil immersion pump 4, and a manhole cover 5. A barrier is installed in the oil storage tank 1. Explosion-proof material 10, the bottom of the tank is also provided with a semicircular cleaning tunnel 7 surrounded by metal mesh 8, and the two ends of the cleaning tunnel reach the sealing head. A cleaning hole 9 is left at its end. A shaft 6 is arranged in the oil storage tank at the corresponding position of the manhole cover 3, and the shaft 6 has four columns 11, and the selection of the columns is an angle steel of 35 × 35 mm; The stringers 12 have surrounded a square frame. Stringer 12 is selected as the flat steel of 40 * 5 millimeters. The upper and lower end surfaces of the four columns are provided with arc-shaped end plates 15, and the lower arc-shaped end plates are on the inner ...

Abstract

An isolated and explosion-proof underground oil tank able to be cleaned and maintained is disclosed. It features that in the underground tank, there are a semi-round cleaning tunnel on its bottom, a square vertical shaft formed by 4 columns and purlins with lower and upper end plates, an internal cylindrical tube is equipped in the vertical shaft and is fitted with isolating and explosion-proof material, and an oil outlet tube whose lower end is connected to a check valve and an immersible pump.

Description

technical field [0001] The invention relates to a cleanable and maintainable barrier and explosion-proof underground oil storage tank, which is an underground barrier and explosion-proof oil storage tank of a gas station, and is a new type of oil storage tank that can be cleaned and maintained conveniently. technical background [0002] Currently, oil storage tanks at gas stations are buried underground. In order to achieve the purpose of barrier and explosion-proof, barrier and explosion-proof materials are installed in the oil storage tank. However, due to the existence of the barrier explosion-proof material in the tank, the barrier in the oil storage tank, the cleaning of the explosion-proof material, and the oil dirt deposited in the cleaning tunnel of the oil storage tank cannot be removed, and the check valve or oil immersion pump connected to the oil outlet pipe cannot be removed Make repairs. It can only be carried out if the barrier and explosion-proof materials ...
