Claim:
An explosion-proof and environment protective oil refueling equipment, comprising: an atmospheric double walled or two layer oil storage tank that can be connected to a refueling machine, the storage tank having an inner chamber; the inner chamber of said storage tank being filled with an explosion-proof material unit made of explosion-proof material that is a multi-layer material unit made of high porosity lamellar materials, and an interlayer between the two-layer tank walls thereof being filled with a high porosity lamellar material; a skid being set under the oil storage tank and the refueling machine; and a fixed supporting part in the explosion-proof material unit for fixing and supporting the unit, and wherein a plurality of said explosion-proof material units is orderly installed in the inner chamber of the oil storage tank, the fixed supporting part is a skeleton set in the space between any two layers of the high porosity lamellar materials of this unit for fixing and supporting the unit, wherein the skeleton selected from the group consisting of (1) an interweaved supporting frame and reinforcing rings, with the reinforcing ring being threaded in the middle of the supporting frame and being fixed onto it, the shape of skeleton corresponding to that of the unit; (2) upright columns being inserted between any two layers of the multi-layer high porosity lamellar materials of the unit and protruding from the upper and lower end faces of unit, and the crossbeam being adjoined with the parts of the upright column protruding from the upper and lower end faces of the unit, (3) more than one of frame, each frame being set between any two layers of the multilayer high porosity lamellar materials of the unit, and more than one of frames having a tops and bottoms that are mutually connected; and (4) two parts, namely the upper and lower skeletons, these upper and lower skeletons respectively including interconnected end frames and inserting frames, the end frames being so set as to covering the upper and lower end faces of the unit respectively, and the inserting frames being inserted and extended through the space between any two layers of the multilayer high porosity lamellar materials of the unit so as to fix and support the unit.
