Abstract
The utility model discloses an oil tank fireproof ventilation head, which comprises a housing (1), a cylindrical net rack (3), a tapered net rack (4) and a base (5). The housing (1) and the cylindrical net rack (3) are connected together through a fastener. The tapered net rack (4) is positioned inside a cavity between the cylindrical net rack (3) and the base (5). The tapered net rack (4), the cylindrical net rack (3) and the base (5) are integrally connected into one piece through fasteners. A silk screen (2) is respectively arranged inside both the cylindrical net rack (3) and the tapered net rack (4). The oil tank fireproof ventilation head provided by the utility model has the advantages of simple structure, easy fabrication, low cost and the like. Due to the adoption of the oil tank fireproof ventilation head, sparks are prevented from entering an oil tank during a fire hazard, while the oil tank is ensured to be good in ventilation performance. Meanwhile, the spreading of the fire hazard is avoided.
Description
Technical field
The utility model relates to the ventilative head of a kind of cargo tank fire prevention.
Background technology
Raising along with modernization; The function of boats and ships is powerful day by day; Facility is also more and more complete, and the potential safety hazard of bringing thus is just more and more, and wherein disaster hidden-trouble is the most general; Though safety measure is done very perfectly now, the secondary disaster that fire causes often causes people's ignorance easily.Endurance maximization when guaranteeing ship's navigation; The oil reserve of cargo tank is increasing, and in a single day the Mars that produces when fire takes place touch oily substance or the higher oil gas of concentration ratio, and fire is triggered at any moment; Cargo tank catches fire and is tantamount to a bomb; Boats and ships are destroyed in moment,, can stop Mars and extinguish Mars so on the ventilation mouth of cargo tank, need a kind of device.
Summary of the invention
In order to address the above problem, the utility model provide a kind of simple in structure, make easily, the ventilative head of the low cheap cargo tank fire prevention of cost, when guaranteeing the cargo tank high ventilation, can when fire takes place, stop the entering of Mars, avoid the expansion of fire.
The utility model has adopted following technical scheme: the ventilative head of a kind of cargo tank fire prevention, and it comprises outer cover, cylinder rack, awl rack and base, the employing fastener is connected between said outer cover and the cylinder rack; The inside cavity of said awl rack between cylinder rack and base adopts fastener to link into an integrated entity between the three; Said cylinder rack is respectively equipped with silk screen with boring in the rack.
Said silk screen is positioned on the cross-sectional plane of cylinder rack; Said silk screen is positioned on the inner peripheral surface of cylinder rack; Said silk screen is positioned on the cross-sectional plane of awl rack; Said silk screen is positioned on the internal conical surface of awl rack; Evenly offer eight rectangular openings on the circumference of said cylinder rack; Evenly offer on the circular conical surface of said awl rack four tri-angle-holed; Said silk screen is a copper wire gauze.
The utlity model has following beneficial effect: the utlity model has simple in structure, make distinguishing features such as easy, with low cost, good permeability, Mars extinguish thoroughly; On the periphery of cylinder rack, be uniformly distributed with eight rectangular openings, the awl rack circular conical surface on be uniformly distributed with four tri-angle-holed, thereby can guarantee permeability to air preferably; The air-flow that is mingled with Mars is behind the ventilative head of outer cover bottom entering; Respectively through cylinder rack, awl rack and base; Get into ventilation mouth at last; In the process of the ventilative head of airflow passes, Mars and cylinder rack, awl rack and copper wire gauze fully collide, extinguish and filter, and avoid Mars to get into the fire expansion that cargo tank causes thereby reach.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, the utility model provides the fire prevention of a kind of cargo tank ventilative head, and it comprises outer cover 1, cylinder rack 3, awl rack 4 and base 5, and the employing fastener is connected between outer cover 1 and the cylinder rack 3; The inside cavity of awl rack 4 between cylinder rack 3 and base 5 adopts fastener to link into an integrated entity between the three; Cylinder rack 3 is respectively equipped with silk screen 2 with boring in the rack 4, and silk screen 2 is a copper wire gauze.In cylinder rack 3, silk screen 2 is positioned on the cross-sectional plane of cylinder rack 3 or is positioned on the inner peripheral surface of cylinder rack 3.In awl rack 4, silk screen 2 is positioned on the cross-sectional plane of boring rack 4 or is positioned on the internal conical surface of awl rack 4.Evenly offer eight rectangular openings on the circumference of cylinder rack 3, the awl rack 4 circular conical surface on evenly offer four tri-angle-holed.
After the utility model is installed to oil tank ventilation pipe outlet,, can produce a large amount of Mars in the combustible material combustion process, after the air-flow that is being mingled with Mars arrives the utility model, produce collision and Mars is extinguished with outer cover when on the ship during presence of fire.But because the irregularity of air flow line; Still have air-flow to get into from the outer cover bottom; When air-flow process cylinder rack, copper wire gauze, awl rack, Mars has experienced collision simultaneously, has extinguished, filtered three processes, when air-flow arrives permeability cell; Wherein there has not been Mars, only trickle cigarette ash after just extinguishing.
