Description
Technical Field
The invention relates to marine equipment, in particular to a toxic cabin ventilation device.
Background
Marine vessels transport various cargo, and there are vessels provided with toxic cabins for transporting volatile toxic chemicals. Because of thermal expansion and contraction or jolt of the ship, toxic substances in the oil tank can accelerate volatilization, the pressure in the tank gradually increases, and hidden danger of explosion exists. In order to avoid the overlarge pressure in the cabin, the ventilation device is usually arranged in the oil cabin to be communicated with the atmosphere, and is closed when the pressure is normal, and ventilation occurs when the pressure is overlarge. The existing ventilation head is easy to block and cause explosion due to improper design and low reliability of internal structure.
Disclosure of Invention
The invention aims to provide a toxic cabin ventilation device with double ventilation release.
The technical scheme adopted by the invention is as follows: the utility model provides a poisonous cabin ventilation unit, includes vertical permeability cell, the bottom UNICOM cabin of permeability cell, and the top of permeability cell is connected with the air pipe head, the middle part of permeability cell is equipped with ventilative branch pipe, and the bottom welding and the permeability cell side of ventilative branch pipe and with the permeability cell UNICOM, the top of ventilative branch pipe is vertical upwards to be set up, and ventilative branch pipe up end is the flange face, installs flange on the flange face, install the rupture membrane between flange face and the flange, the up end of ventilative branch pipe is covered to the rupture membrane.
Further, the rupture disc is a metal foil.
Further, the mounting frame is fixedly welded at the top of the fixing flange, and the protection cover plate for covering the explosion-proof film is fixed at the top of the mounting frame.
Still further, the air pipe head is connected to the top of the air permeability pipe by a flange, the air pipe head is an inverted cone-shaped inner cavity, a floating ball is arranged in the inner cavity, and the floating ball is blocked between the inner cavity and the air permeability pipe under the action of gravity; the bottom of the inner cavity is communicated with the ventilation pipe, two sides of the inner cavity are respectively provided with a ventilation opening, the outer sides of the ventilation openings are respectively provided with a housing, and the housings are downwards opened.
After the technical scheme is adopted, the beneficial effects of the invention are as follows: on the basis of the existing ventilation pipe and air pipe head, a ventilation branch is arranged to release pressure in a mode of blasting an explosion-proof film by air pressure, so that explosion caused by unstable structure of the existing structure is avoided.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The following detailed description of the invention refers to the accompanying drawings, which illustrate specific embodiments of the invention: as shown in the figure, the toxic cabin ventilation device comprises a vertical ventilation pipe 1, wherein the ventilation pipe 1 extends out of the outer side of a deck, the bottom of the ventilation pipe 1 is communicated with a cabin, the top of the ventilation pipe 1 is connected with an air pipe head 2, the air pipe head 2 is connected to the top of the ventilation pipe through a flange 3, an inverted cone-shaped inner cavity 4 is arranged in the air pipe head 1, the bottom of the inner cavity 4 is communicated with the ventilation pipe 1, two sides of the inner cavity 4 are respectively provided with a ventilation opening 5, a housing 13 is respectively arranged on the outer side of the ventilation opening 5, and the housing is opened downwards. A floating ball 6 is arranged in the inner cavity 4, and the floating ball 6 is blocked between the inner cavity 4 and the ventilation pipe 1 under the action of gravity;
the middle part of ventilative pipe 1 is equipped with ventilative branch pipe 7, and the bottom welding of ventilative branch pipe 7 and ventilative pipe 1 side and with ventilative pipe 1 UNICOM, the vertical upward setting in top of ventilative branch pipe 7, and ventilative branch pipe 7 up end is flange face 8, installs flange 9 on the flange face 8, install rupture membrane 10 between flange face 8 and the flange 9, rupture membrane 10 covers ventilative branch pipe 7's up end completely, and the rupture membrane is metal foil such as tin foil, aluminium foil etc. or is plastic film etc.. The mounting bracket 11 is fixedly welded at the top of the fixed flange 9, and the protection cover plate 12 for covering the explosion-proof film is fixed at the top of the mounting bracket 11.
In the use process, when the pressure in the cabin is increased, the floating ball 6 is jacked, and the air in the cabin is discharged from two sides through the air vents 5 at two sides of the inner cavity 4. The housing 13 outside the vent 5 effectively prevents the back-flow of rainwater. The middle part of the ventilation pipe 1 is provided with a ventilation branch pipe 7, an explosion-proof membrane 10 is fixed at the outlet of the ventilation branch pipe 7, and when the air pipe head 2 fails, the gas blasts the explosion-proof membrane 10 to release pressure, thereby preventing explosion. The protection cover plate 12 is arranged at the top of the explosion-proof film to prevent the explosion-proof film from being damaged by people.
