Abstract
The utility model relates to a multi-ring environmental protection type internal floating disc for an oil storage tank, which is mainly composed of an outer ring beam, a transverse beam, a positioning beam, a floating beam, a cover plate, a float, a floating disc manhole, a vent valve and an oil-measuring device. The utility model is characterized in that a plurality of ring float beams are arranged under the transverse beam and the positioning beam, the float is in various shapes, such as aluminium pot shape, spherical shape, etc., the floating body is the jointless structure, the cover plate is assembled by a plurality of aluminum plates using bolts, airbag sealing members are arranged on the floating disc manhole and the sealing position of the upper cover of the vent valve, the inner floating disc has good strength and rigidity, the dropping and crack of the floating disc and the 'click' gas rush can be effectively prevented, the oil evaporation is prevented, the environment is purified, the fire accident is reduced, and the cost is decreased.
Description
The utility model relates to a kind of interior floating plate of petrol storage tank, particularly floating plate in a kind of many rings of petrol storage tank environment-friendly type.
Interior floating plate is a kind of sealing arrangement that swims in the petrol storage tank on the oil storage liquid level along with the oil product liquid surface lifting, main effect is that oil product and outside air are isolated, with volatilization and diffusion, purifying ecological environment, minimizing disaster hidden-trouble, the reduction energy loss that reduces oil product.
The interior floating plate that present domestic petrochemical industry petrol storage tank generally adopts is a few years ago from " the build-up type aluminum in floating plate " of external introduction, should adopt high-intensity lightweight aluminium by interior floating plate, be processed into zero, parts at originating firm earlier, send into again and be assembled into whole floating plate in the petrol storage tank, its processing and manufacturing is simple, very convenient to old petrol storage tank transformation, have plurality of advantages such as in light weight, easy to maintenance, therefore extensively promoted the use at home.
But, in actual applications, when being housed, the petrol storage tank of floating plate in this have heavy card, cracking and fire to take place, badly influence the safety of petrol storage tank like this and to the pollution of surrounding environment, major defect of floating plate is in this:
1, the layout of individual components is reasonable inadequately, causes integral structure to have weak link, easy so heavy card, the cracking that causes floating plate; And partly overemphasized intensity and rigidity at some, cause cost significantly to improve;
2, the single volume of float is too little in the floating plate, fails to make full use of the maximum volume that the tank body hand-hole can pass through, and the required float quantity of whole floating plate is increased, and has strengthened manufacturing cost;
3, the poor sealing performance at some sealing position, oil and gas leakage is more serious;
4, poor for contingent in the jar " gas hits " phenomenon to the holding capacity of the damaging impact of floating plate, cause indivedual floating plates cracking that falls apart.
The purpose of this utility model is the interior floating plate of many rings environment-friendly type that a kind of petrol storage tank will be provided; the floating plate topology layout is reasonable in being somebody's turn to do; have good intensity and rigidity and failure-free air-tightness; can prevent effectively that floating plate from sinking card, cracking and oil gas and leaking outside; can guarantee the safety of petrol storage tank, and surrounding environment is effectively protected.
The purpose of this utility model is achieved in that
Floating plate in a kind of many rings environment-friendly type of petrol storage tank, mainly include cycle beam, crossbeam, positioning beam, float beam, float, cover plate, floating plate hand-hole, connection for bbreather pipe, oil-measuring apparatus, pillar, anti-rotation device, static conducting device and flexible seals, it is characterized in that: a plurality of annular float beams are set under crossbeam and positioning beam, and rectangular distribution is provided with a plurality of floats under this float beam and cycle beam; This cover plate is to be assemblied with tie bolt by the polylith aluminium sheet.
This float is made up of buoyancy aid and top cover, is aluminum pot shape, sphere, elliposoidal, ship shape or spherical, and its buoyancy aid is a jointless structure, and buoyancy aid and top cover are that air-tightness welding or seccotine are bonding.
The loam cake of this floating plate hand-hole and connection for bbreather pipe and sealing place of hole body are provided with bellows seal spare.
Sealing place of this oil-measuring apparatus is provided with double-deck oil-resistant rubber slab, is made up of two rubber plates that middle opening is staggered for every layer.
The utility model has improved the performance of the interior floating plate of existing petrol storage tank, make oil product and air in the petrol storage tank remain isolated condition, played the effect that stops oil evaporation in the petrol storage tank, purifying ecological environment, reduces disaster hidden-trouble, reduction energy loss and manufacturing cost, its advantage is:
1, because the structure design of annular float beam and float, and cover plate improved the floating reliability of floating plate, static state and dynamic stability with the assembly unit of tie bolt, and this floating plate comprehensive technical indexes is significantly improved;
2, because this floating plate hand-hole and sealing place of connection for bbreather pipe loam cake are provided with bellows seal spare, when " gas hits " takes place in can effectively bearing jar to the damaging impact of this floating plate;
3, double-deck oil-resistant rubber slab is adopted at oil-measuring apparatus sealing position, can play good sealing usefulness.
Further specify the technical solution of the utility model and embodiment below in conjunction with accompanying drawing.
Description of drawings:
Fig. 1 is the utility model petrol storage tank front elevation;
Fig. 2 is a plan sketch of the present utility model;
Fig. 3 is a spherical float structural representation of the present utility model;
Fig. 4 is floating plate hand-hole of the present utility model and connection for bbreather pipe loam cake hermetically-sealed construction cutaway view;
Fig. 5 is an oil-measuring apparatus hermetically-sealed construction cutaway view of the present utility model.
As shown in Figure 1, 2, the utility model mainly includes cycle beam 21, crossbeam 22, positioning beam 23, float beam 4, float 3, cover plate 5, floating plate hand-hole 1, connection for bbreather pipe 6, oil-measuring apparatus 8, pillar 9, anti-rotation device 7, static conducting device 11 and flexible seals 10, it is characterized in that a plurality of annular float beams 4 being set for 23 times, a plurality of floats 3 are set at this float beam 4 and 21 times rectangular distributions of cycle beam at crossbeam 22 and positioning beam; This cover plate 5 is to be assemblied with tie bolt by the polylith aluminium sheet.
As shown in Figure 4, the loam cake 41 of floating plate hand-hole 1 of the present utility model and connection for bbreather pipe 6 and the sealing between the hole body 43 are made up of bellows seal spare 42, like this floating plate hand-hole 1 not still for assembling, the maintainer is into and out of use, when still not supplying oil extraction, regulates connection for bbreather pipe 6 floating plate bottom pressure, in the time of simultaneously can oil product air pressure be too high in petrol storage tank, allow oil gas emit thus, in case when " gas hits " takes place in the jar, to the damaging impact of this floating plate.
As shown in Figure 5, oil-measuring apparatus 8 of the present utility model is the usefulness for testing staff's metering, mensuration oil products parameters, the sealing position of this oil-measuring apparatus 8 is made up of double-deck oil-resistant rubber slab 51 and hole body 52 sealings, each layer oil-resistant rubber slab 51 is made of the rubber plate that opening staggers two centres, to guarantee that the metering copper rod can freely pass through, again can excellent sealing.
Make according to said structure, can constitute the utility model---floating plate in a kind of many rings environment-friendly type of petrol storage tank.
