Description
Technical field
It the utility model is related to marine ship field, and in particular to the ventilation head of the anti-oil mixing with water of marine ship cargo tank.
Background technology
Endurance maximizes during in order to ensure ship's navigation, and the oil reserve of cargo tank is increasing.Due to expanding with heat and contract with cold or
Ship jolts, and the oil in cargo tank can be accelerated to volatilize, and cargo tank pressure becomes larger, and has hidden peril of explosion.In order to avoid in cargo tank
Pressure is excessive, it will usually installs ventilation head and atmosphere in cargo tank.Existing ventilation head is improper due to designing, and easily makes outside
Seawater enters in cargo tank, reduces the quality of oil.When jolting, the oil in cargo tank can be spilt from ventilation head, pollute environment.
The content of the invention
The purpose of this utility model is to provide a kind of marine ship oil tank ventilation device for being capable of water-oil separating.Can either
Pouring in down a chimney for water effectively is avoided, while the oil spilt is collected separately, avoids polluting caused by oil mixing with water.
The technical scheme that the utility model is taken is：
Marine ship oil tank ventilation device, including oil sump tank, oil sump tank are installed on ship deck；It is provided with oil sump tank
Oil-collecting box cavity is divided into upper and lower two cavitys, oil sump tank upper box open top by dividing plate, dividing plate, and oil sump tank lower box is
Seal case；Oil sump tank lower box is connected through vertical ventilation duct with cargo tank, and oil sump tank lower box is higher by the top of ventilation duct
Bottom surface；Ventilation head is installed, ventilation head bottom is through dividing plate and oil sump tank lower box UNICOM, the crown of breathing freely in oil sump tank upper box
Portion closes, and is welded with baffle plate in the cavity on ventilation head top, air vent is provided with baffle plate, baffle center is installed with vertically
Piston shaft, piston is serially connected with piston boit, piston slides up and down along piston shaft, piston covering air vent；The side on ventilation head head
Face is higher than piston by right angle discharge pipe and extraneous air UNICOM, right angle discharge pipe with ventilation head junction, and right angle discharge pipe goes out
Air port straight down and is oriented in oil sump tank upper box.
Further, bleeder valve is installed on the bottom surface of the oil sump tank lower box.
Yet further, drain plug is installed on the oil sump tank top box body side surface.
After taking above technical scheme, the beneficial effects of the utility model are：Ventilation head is divided into two sections, one section and cargo tank
Connection, the oil spilt concentrate on the lower box of oil sump tank, prevent from overflowing；The other end and atmosphere, made by piston in gravity
Water is avoided to pour in down a chimney under, while when pressure is big, depended on pressure jacks up piston decompression；Two sections of nowels by oil sump tank of ventilation head
Body realizes the circulation of air；The lower box of oil sump tank collects oil, and the upper box of oil sump tank collects water, avoids the mixing of profit.
The technical program is simple in construction, can efficiently separate profit and reclaim, prevent from polluting.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：Oil sump tank 1, oil sump tank upper box 11, oil sump tank lower box 12, ventilation head 2, baffle plate 21, air vent 22, erect
Straight piston shaft 23, piston 24, right angle discharge pipe 25, dividing plate 3, bleeder valve 4, drain plug 5, ventilation duct 6.
Embodiment
Specific embodiment of the present utility model is further described below in conjunction with accompanying drawing：
As illustrated, marine ship oil tank ventilation device, including tubbiness or square oil sump tank 1 and ventilation head 2.Oil-collecting
Case 1 is installed on ship deck；Middle part in oil sump tank is provided with dividing plate 3, and the outline of dividing plate 3 is welded in the inwall of oil sump tank 1,
The inner chamber of oil sump tank 1 is divided into upper and lower two casings 11,12 by dividing plate 3, is provided with and is released on the bottom surface of oil sump tank lower box 12
Valve 4, oil sump tank upper box 11 are provided with drain plug 5 on side.The open top of oil sump tank upper box 11, oil sump tank lower box 12 are
Seal case.Oil sump tank lower box is higher by under oil sump tank through vertical ventilation duct 6 and cargo tank inner chamber UNICOM, the top of ventilation duct 6
The bottom surface of casing 12；Ventilation head 2 is installed, the top of ventilation head 2 is higher by the top surface of oil sump tank 1 in oil sump tank upper box 11；Thoroughly
First 2 bottom of gas is through dividing plate 3 and the UNICOM of oil sump tank lower box 12, and the top seal of ventilation head 2, the cavity on the top of ventilation head 2 is interior to be welded
Baffle plate 21 is connected to, is provided with air vent 22 on baffle plate 21, the center of baffle plate 21 is installed with vertical piston shaft 23, on piston boit 23
Piston 24 is serially connected with, piston 24 is slided up and down along piston shaft, and piston 24 is covered on air vent 22 in a free state；Ventilation head
The side on 2 heads is higher than piston by right angle discharge pipe 25 and extraneous air UNICOM, right angle discharge pipe 25 with the junction of ventilation head 2
24, the air outlet of right angle discharge pipe 25 straight down and is oriented in oil sump tank upper box 11.
In use, when tank pressure is normal, fuel tank is in air-tight state.When fuel tank does not have pressure increase,
Piston is jacked up, and discharges pressure.When ship jolts, enter after being spilt by self-ventilation pipe 6 in oil sump tank lower box 12 and received
Collection.Because ventilation duct 6 is two sections of bodys with ventilation head 2 and is shifted to install, oil can not be spilt from ventilation head 2, avoid pollution.When
When raining or having inwelling, because the device import is right angle discharge pipe 25, shipwreck is to pour in down a chimney, and the work in ventilation head 2
The covering air vent of plug 24, Gu Shui cannot be introduced into oil sump tank lower box 12, avoid the pollution to oil.
