Description
Technical field
The present invention relates to chemical industry environmental protection field more particularly to a kind of single disc-type internal-floating cover of stock tank.
Background technique
With petrochemical industry unit in all parts of the country and each major oil companies and oil plant, port and pier, traffic, power plant
And army rear service department, for being widely used for oil mass, oil storage facility be also it is more and more, it is most common or oil storage tank to make
With, wherein storage tank floating plate is essential energy-saving environmental protection device in these oil storage tanks, and internal-floating cover of stock tank is that one kind passes through buoyancy
It is allowed to the energy-saving environmental protection device being covered on liquid level gone up and down with storage tank liquid surface lifting.To reduce medium volatilization in storage tank, drop
Low-loss is energy saving, protects environment, floating plate in this is added in storage tank.Storage tank by installation floating plate sealed storage medium,
It reduces medium temperature and reaches energy saving, protect the effect of environment.Currently, the structure and style of storage tank floating plate is also a variety of more
Sample is generally divided into steel formula iron buoyancy module floating plate, float-type floating plate, the board-like floating plate of honeycomb, floating box type floating plate, although this few class floating plate
Respective advantage is suffered from, but also exists simultaneously different degrees of hidden danger, steel formula iron buoyancy module floating plate is high, stupid due to cost
Weight, construction period are long, need scene to get angry welding, buoyancy unit is few, and the easy chuck of easy to leak causes to deform, maintenance is not easy to groove tank
And expense is high；The leakproofness of float-type floating plate is not strong, there is volatilization space, each self-dispersing of buoyancy unit, vulnerable to disengaging medium shadow
It rings and generates fluctuation, cover board is thin, be easy to cause deformed damaged, and service life is short, and also not can guarantee people can freely walk in floating roof
Construction；Although the board-like floating plate of honeycomb has breakthrough and improves in configuration aspects, leakproofness is enhanced, it is convenient to construct, and is easy group
Dress, but its structure is excessively complicated, inconvenience is brought for the installation of other floating plate auxiliary accessories, due to auxiliary facility
It is not perfect, so that the safety of floating plate itself is had a greatly reduced quality, and lack effective discharge to oil gas；Floating box type floating plate buoyancy tank knot
Structure is insecure, and buoyancy tank quality can not detect, easy to damage by medium fluctuation buoyancy tank, dismantles the buoyancy tank for having medium and causes safe thing
Therefore often there is declaration of an accident in recent years, therefore state security department has sent the documents at present gradually to ban such floating plate.And it is above-mentioned
Several floating plate sealings only inhibit the volatilization of liquid level, and not to reservoir walls, it is no group that remaining medium volatilization, which control effectively,
Knit discharge.
Summary of the invention
The object of the present invention is to provide a kind of whole floating plate is light-weight, structure is simple, more stable and firm, safe and reliable
Single disc-type internal-floating cover of stock tank.
The technical scheme is that：A kind of single disc-type internal-floating cover of stock tank, including floating plate ontology, several floating plate pillars,
Floating plate edge member is directed through the attachmentes such as device, oil-measuring apparatus, manhole, automatic ventilation valve, static conducting device, the floating plate
Ontology is connected according to one word close-packed arrays of horizontal direction using welding or bolt mode are fixed from each other by several float tubes
It connects.Flame retardant coating is arranged in floating plate entirety outer surface, and the flame retardant coating and floating plate ontology are whole covering, and the flame retardant coating is sealant
Matter has flame retardant efficiency.
The float tube is square hollow or rectangular tube, material selection stainless steel material or aluminum alloy material.
It is connected between the float tube using bolt or welding manner.
The float tube is divided into two class of standard pipe and shape tube, and standard pipe on the outside, collectively forms disk in middle part, shape tube
The floating plate surface of shape.One word close-packed arrays of standard pipe constitute standard single-deck plate body, the tank body of same size, standard single-deck plate body
Size it is unified, standardize processing in batch in production, be used interchangeably using position.
Shape tube constitutes special-shaped single-deck plate body, and according to tank diameter, the data such as periphery radian, patterning process is formed.
Sealing sleeve pipe is set between floating plate and tank skin, and one end of the sealing sleeve pipe is to be fixedly connected with floating plate ontology, separately
One end is fixedly connected with tank top, forms sealing space between sealing sleeve pipe and the inner wall of storage tank.
The sealing sleeve pipe is extension type casing, and several gas vents are equipped at the top of the sealing sleeve pipe.
The shape of the sealing sleeve pipe cross section is identical as the cross-sectional shape of storage tank, and the diameter of the sealing sleeve pipe
Less than the diameter of storage tank, it is slightly larger than floating plate outer diameter.Under this setting, the oil gas of volatilization will be remained in sealing space, reached
To after a certain amount of, can be discharged by gas vent rule.
The beneficial effects of the present invention are：The floating plate is directly all using square hollow stainless steel tube or square hollow aluminum pipe
It connects and composes, structure is simple, and this hollow structure can mitigate the weight of whole floating plate；
It is equipped with one layer of flame retardant coating in floating plate body surface, and the flame retardant coating has flame retardant efficiency using sealing colloid, into
One step ensures safety；
The shape of floating plate ontology after welding fabrication is identical as reservoir walls shape, and its diameter is less than wet tank
The diameter of inner wall can be conducive to the installation of whole floating plate in this way；
In addition, sealing sleeve pipe is arranged in the inside of storage tank, using extension type metal material, the shape and storage of cross section
The cross-sectional shape of tank is identical, and the diameter of the sealing sleeve pipe is slightly less than the diameter of storage tank, so that outside sealing sleeve pipe
Sealing space is formed between side and reservoir walls, this space is sealed in oil gas wherein, after reaching a certain amount of, allows oil gas
It is discharged from the gas vent at top, realizes organized discharge.
Entire floating-plate device structure is simple, installs easy to operate, light-weight, long service life, and flame retardant property is strong.
Thus the floating plate of float tube structure composition and steel floating plate compare, and floating plate structural strength is close, but floating plate weight
Light.Used metal material has more corrosion resistance in storage tank medium, is not necessarily to Corrosion Maintenance, floating plate service life
Longer, equipment processing and fabricating cost is low.
It is compared by the floating plate and float-type floating plate of float tube structure composition, floating plate structural strength has been greatly enhanced, has been more
Stable and secured, more safe and reliable single disc-type internal-floating cover of stock tank.Floating plate integrally immerses in liquid, without oil gas volatilization sky
Between, floating plate more safety and environmental protection.
