Description
Technical field:
The utility model relates to a kind of in fluid storage equipment and cover the device that liquid-to-air is isolated on the liquid level, is specifically related to a kind of staggered floor and strengthens the flexible floating top of membrane type.
Background technology:
In fluid storage equipment, the two-phase mass exchange takes place for preventing and reducing the gas-liquid two-phase interface, prevent the air loss of liquid, ensure the chemistry and the stable physical property of liquid, " floating top " device usually is installed in storage facilities institute liquid storage surface, the gas-liquid two-phase medium is isolated, thereby reach contact that stops two-phase medium and the purpose that minimizing evaporates.
At present, occur some combination type floating tops on the market, as the patent No. be: the utility model patent of ZL99233384.9, it is formed by connecting by bolt or screw by parts such as face, floating block (floating ring), upper press ring, following pressure ring, sealing bands.The bolt of plastics quality or screw intensity are limited, and also limited with the fastening degree of pressure ring spare, after operation a period of time, loosening or phenomenon of rupture take place easily; Adopt metal bolts or screw, when meeting the corrosive property liquid level, corrosion takes place easily then, both influenced the stability on floating top, can pollute the liquid of storage again, loosening bolt or the screw component that drops also may take place be inhaled in the pump, cause device damage.The floating top of assembly type must be overhauled through (general 3～5 years) behind certain cycle of run, needs during maintenance to float the top overall pulling down, owing to adopt bolt or screw to connect when installing, floating top after the dismounting is difficult to recover, and when fluid storage equipment overhauls, also need remove floating top.Have in order to overhaul conveniently, at device interior the maintenance support has been installed also when installing on floating top.For addressing the above problem, technical personnel has been researched and developed the flexible floating top of a kind of membrane type, as the patent No. be: the utility model patent of ZL200520096791.9, the floating top of whole flexibility is made up of one deck monofilm, can not produce phenomenons such as spare and accessory parts become flexible, fall apart, rupture and come off, do not have false liquid level phenomenon yet and produce, stable.Main material is a long-chain organic polymer integral material, membrane material is flexible big, rebound resilience is good, when storage facilities overhauls, can will float to push up to roll at device interior and stack, overhaul of the equipments is not produced a bit influence, but this whole single-layer membrane structure just is inconvenient to use on some large-scale liquid storage equipment, because its area is excessive, the processing and fabricating of monofilm trouble, its intensity of large-area monofilm also a little less than, easily break, and the phenomenon of turning over to the center around occurring easily in use, also must manually adjust and reset.
The utility model content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of staggered floor to strengthen the flexible floating top of membrane type, its used integral membrane is to be strengthened being formed by connecting by the mutual staggered floor of a plurality of film bodies, it no longer is the individual layer integral membrane, avoid the individual layer integral membrane excessive because of its area, form at center membrane littlely fall into, periphery turns over phenomenon in forming when current are excessive, too urgent, it is easy for installation, coverage rate is high, maintenance is simple and easy, long service life, strong to device shaped and structure adaptability.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of staggered floor is strengthened the flexible floating top of membrane type, it comprises integral membrane 1, the flexible contact between integral membrane 1 and the liquid storaging device 2, wherein: described integral membrane 1 is formed by fixedly connecting by at least two film bodies 4 staggered floors, the joint face that the end face of its junction is provided with 3, two interconnective film bodies 4 of film body strap stiffener is identical inclined-plane, angle of inclination.
Further, the angle of inclination of the joint face of described two interconnective film bodies 4 is 45 degree.
Further, described film body 4 is shaped as strip shape or/and circular arc.
Further, the shape of described integral membrane 1 is identical with the level cross-sectionn shape of liquid storaging device 2.
The beneficial effects of the utility model are:
1, it is excessive because of area that the utility model has overcome existing individual layer integral membrane, and center membrane forms and littlely falls into, periphery turns over phenomenon in forming when current are excessive, too urgent;
2, the joint face of interconnective two film bodies of the utility model is the identical inclined-plane of angle, it has increased the connection area, and the end face of joint face is provided with the film body strap stiffener simultaneously, makes connection more firm, improve the Joint strenght of film body, strengthened whole film strength and rigidity;
3, film body of the present utility model adopts high-molecular organic material to make, anti-water vapor permeable ability is strong, density is little, corrosion stability is strong, airtight, ductility good and rebound resilience good;
4, the utlity model has simple in structure, easy for installation, coverage rate is high, maintenance is simple and easy, long service life, to characteristics such as device shaped and structure adaptability are strong, be desirable oxygen barrier liquid level obturator at present.
