Description

Quick assembly of chute type oil tank floating roof

The present invention is carried out with a way to quickly assemble a single piece is more readily serviceable for floating roof tank, in particular a streamlined structure by longitudinal beams, transverse beams, upper press beam / beams under the pressure, and the fixed locking plate assembly The frame unit is formed, and the floating body unit is locked to obtain a more stable and compressive floating body structure.

In the conventional oil storage tank structure, in addition to the hollow tank body for oil storage, a floating roof device is also required in the tank. As the oil storage liquid level rises or falls, the floating roof device closely adheres to the oil storage liquid On the surface, it can reduce the volatilization of oil and gas in oil storage, and achieve the effect of environmental protection and energy saving.

The Republic of China Patent No. M379582 "Pontoon Body for Oil Tank Floating Roof Device" reveals a typical conventional floating roof device for oil tank storage. This type of floating roof device relies on a number of cylindrical buoys to support the upper frame and the skin floating in the oil tank. On the liquid surface, the buoyancy unit is separated due to the cylindrical structure which cannot be completely connected in a plane. When the liquid enters and exits the liquid, the floating body units are separately stressed, which easily causes the floating plate to deform and damage the sinking plate.

In addition, the above-mentioned previous proposal is because the cylindrical structure cannot be completely connected in a plane instead of covering the liquid storage, resulting in a space between the floating roof and the liquid storage, which cannot effectively reduce volatilization. It is easy to generate accumulated concentration in this space, and then Cause safety concerns for oil storage tanks.

The Republic of China Patent No. TW151010 "Aluminum Honeycomb Core Internal Floating Roof Structure for Petroleum Tanks" discloses a typical conventional honeycomb floating roof device for oil tank storage. This floating body unit uses upper and lower aluminum plates and honeycomb cores to make floating plates. (Sandwich style) As shown in Figure 5, the edge of the floating plate is sealed and assembled by adhesive. After long-term immersion in the liquid storage, it is often peeled off due to the infiltration of the adhesive, which causes the floating roof to damage the sink plate.

The Republic of China Patent No. I435834 "Oil Tank Floating Roof Device" patent discloses a typical conventional floating roof device for oil tank storage. This kind of floating roof device is formed on the shell of the floating unit to form an extended fixed edge (overhanging edge). Each floating body unit is connected by overlapping and locking between each extending fixed side and the vertical frame rod and the horizontal frame rod, as shown in the fourth and fifth diagrams; In this way, the shell forms a laterally extending fixed edge to be fixed to the beam frame. All stresses are generated on the laterally extending fixed edge of the outer side of the floating body unit. Under the severe shaking of oil products, the floating body unit Flexing to the extended fixed side causes the welding seam to rupture, thereby causing the liquid storage to enter the floating body unit and causing damage to the sink.

The Republic of China Patent No. M486633 "Oil Tank Floating Roof Unit" patent discloses a typical conventional floating roof equipment for oil tank storage, as shown in the figure, the same as the previous case; because this method relies on the shell to form a laterally extending fixed edge When fixed with the beam frame, all stresses are generated on the laterally extending fixed side of the floating body unit. Under the violent shaking of the oil product in and out of the floating body unit, the welding seam will be broken due to the deflection of the laterally extending fixed side. The liquid storage enters the floating unit and causes damage to the sink plate.
