Specific embodiment
Below against attached drawing, by the description of the embodiment, making further details of theory to the specific embodiment of the invention
It is bright, to help those skilled in the art to have more complete, accurate and deep reason to inventive concept of the invention, technical solution
Solution.
As Figure 1-Figure 5, the present invention provides a kind of outdoor wet tanks, including upright tank body 1, the tank body 1
It is equipped with oil inlet 17.The oil inlet 17 includes the oil inlet interface equipped with flange, and the interface end of the oil inlet interface is covered with
17 strainer of oil inlet, the end that the oil inlet interface protrudes into the tank body 1 are equipped with interface tube and connect with the oil pipe for passing through nitrogen sealing,
Oil inlet interface flanged joint has feed cover, and the feed cover is equipped with the through-hole of insertion oil inlet pipe.Through-hole can be connected through a screw thread
Capping seal.
Manual oil outlet is additionally provided at the top of tank body 1, the sealing cover 5 that the manual oil outlet is provided with Non-return air valve 19 covers
Firmly.Manual oil outlet is from top to bottom successively arranged sealing cover mounting flange 20, oil outlet filter screen 21 and grid 22, sealing cover peace
Dress flange 20 is connected with the sealing cover 5.Between the sealing cover 5 and the sealing cover mounting flange 20 and the sealing
Lid 5 and the tank body are designed with sealing structure between 1 top.The manual oil outlet lower end is connected to oil liquid isolated area 6, oil liquid
Isolated area 6 is the column marker space being located in tank body 1.Oil liquid isolated area 6 passes through nitrogen sealing and leads to 1 bottom of tank body, described
6 bottom sidewall of oil liquid isolated area is equipped with liquid relief valve 18, and 6 top of oil liquid isolated area is equipped with and is connected to the nitrogen sealing
Non-return air valve 19.
When pouring into liquid manually, sealing cover 5 is opened, air can enter oil liquid isolated area 6, the liquid level one of oil liquid isolated area 6
As can be concordant or be higher than liquid level in tank body 1 because liquid relief valve 18 is only after 6 oil liquid of oil liquid isolated area reaches certain pressure
Can just allow wherein oil liquid flow out to tank body 1, this can prevent liquid relief valve 18 exposing cause air to enter.After pouring into oil liquid, oil
Liquid enters tank body 1 through liquid relief valve 18, covers sealing cover 5 after the completion of supplement oil liquid and is tamping.At this moment in oil liquid isolated area 6
With air, must discharge it.It is filled with nitrogen, nitrogen sealing is inflated by Non-return air valve 19 into oil liquid isolated area 6, the nitrogen being filled with
Air can be discharged from the Non-return air valve 19 on sealing cover 5 for gas, guarantee that wherein oil liquid is sealed by nitrogen, forms nitrogen sealing.In this way
It needs the storage tank for pouring into liquid manually also to can guarantee fluid isolation in air certain situations, prevents its spontaneous combustion.
Liquidometer is equipped at the top of the tank body 1, the measuring rod of the liquidometer is extend into the tank body 1.1 top of tank body
Liquidometer installing port equipped with flange arrangement, liquidometer are the connecting rod floating ball lever meters being fixed on flange arrangement, pass through setting
Floating ball on measuring rod measures liquid level.Liquidometer is mounted on liquidometer installing port by being equipped with the flange of sealing structure,
Measuring rod is extend into always close to 1 bottom position of tank body, for detecting liquid height.
1 upper side of tank body is also communicated with nitrogen pipeline 2, and the nitrogen pipeline 2 is equipped with nitrogen envelope valve 11 and passes through
Pressure reducing valve 15 is connected to the outlet of nitrogen gas tank 16, and ventilating bent-tube 4 is equipped at the top of the tank body 1, is equipped at the ventilating bent-tube 4 unidirectional
Outlet valve 13.1 inside upper part of tank body is equipped with nitrogen holding tank 12, and the nitrogen holding tank 12 is by being equipped with breather valve 14
Opening be connected to the nitrogen sealing in tank body 1, the ventilating bent-tube 4 is communicated to nitrogen holding tank 12, and the breather valve 14 is exhaled
The powerful expiration pressure in the one-way breather valve 13 of air pressure.
Flammable liquid and air exclusion are prevented into spontaneous combustion by being filled with the nitrogen formation nitrogen sealing on top in this way, ensure that liquid
Body will not leak easily volatilization occurs.Nitrogen envelope valve 11 guarantees that air pressure maintains level of security in tank body 1, releases liquid gas
Pressure drop low energy is automatically replenished nitrogen, and after liquid is added, extra nitrogen can enter nitrogen holding tank 12 by breather valve 14, guarantees tank
Body 1 and extraneous normal pressure difference.Due to the powerful expiration pressure in the one-way breather valve 13 of the expiratory pressure of breather valve 14,
There is no concern that ambient atmos enter tank body 1.When temperature increases or liquid is added, nitrogen pressure is increased in tank body 1, and nitrogen is temporary
Depositing pressure in case 12 should be suitable with the expiration pressure of one-way breather valve 13, therefore 1 nitrogen of tank body can be discharged into nitrogen holding tank 12,
It is discharged again through one-way breather valve 13.When mercury dropped or discharge liquid, air pressure reduces in tank body 1, and tank body 1 seals valve from nitrogen first
11 obtain nitrogen.If nitrogen pipeline 2 is because nitrogen cannot be replenished in time in failure or nitrogen deficiency, air pressure drops to centainly in tank body 1
Nitrogen therein can be added to nitrogen sealing by breather valve 14 by level, nitrogen holding tank 12, and the short time does not influence storage tank use,
It sets apart and repairs ventilation.
1 lower side of tank body is equipped with oil outlet 7, and 7 end of oil outlet is equipped with shut-off valve 9.1 bottom of tank body is
Back taper, 1 bottom centre of tank body of the back taper are equipped with slag-drip opening 8, and 8 end of slag-drip opening is equipped with shut-off valve 9.Tank body 1
Bottom has circumferentially been equidistantly positioned at least three stabilizer blades 10 in peripheral region.
Around cooling water pipe 3 is fixed with, the cooling water pipe 3 is arranged below towards the tank 1 upper side of tank body
The spray head of body 1, the cooling water pipe 3 are equipped with the water inlet line being connected with cooling water tank, and the water inlet line is equipped with cooling water
Valve.Temperature inductor is equipped on the outside of the tank body 1 and is connected to the wireless communication device of temperature inductor, and the cooling water valve is
Electric control valve, device is signally attached to safety control module, the security control mould to the temperature inductor by wireless communication
Block is electrically connected with electric control valve.Safety control module can will obtain information compared with safe temperature, when temperature reach a certain height,
Safety control module can allow cooling water valve to be opened through spray head to 1 surrounding of tank body into spraying cooling automatically, both can be reduced liquid and wave
Hair vaporization, and high temperature is avoided to lead to the probability of liquid spontaneous combustion.The structure and nitrogen plugging structure above-mentioned cooperate, which can prevent
Only liquid vaporization is revealed, to the normal barometric pressure in liquid cooling, maintenance tank body 1, substantially increases the safety of outdoor wet tank
Property.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
