The utility model relates to an oil storage tank body, especially an oil storage tank with take out oil pipe.
Background
Oil storage tanks used in the field of oil and gas transportation at present are generally provided with an oil extraction port at a lower position thereof, and an oil extraction pipe is extended from the oil extraction port into the oil storage tank to extract oil. The oil extraction pipe is usually in a straight pipe or spiral pipe structure and is assembled in the oil extraction port through welding or flange connection. Because dirty oil exists at the bottom of the oil storage tank, the oil pumping port of the oil pumping pipe is required to be higher than the bottom of the oil storage tank by a certain distance. In general, the portion of the oil well pipe extending into the oil storage tank is short, but there is a problem in that the dirty oil at the bottom of the oil storage tank can be easily pumped out together due to a siphon effect or the like. For this purpose, it is necessary to extend the oil pumping pipe as far as possible into the oil storage tank to a central position, but there is a problem in that the sealing pressure at the oil pumping port at the wall of the oil storage tank is increased and the sealing performance is poor because the oil pumping pipe is generally in a straight pipe or spiral pipe structure. In order to solve the problem, the support is often required to be arranged on the bottom surface inside the oil storage tank to support the oil pumping pipe, but the structure is complex, and the operation of washing, cleaning and the like of the oil storage tank is not facilitated, so that the oil storage tank is not convenient to maintain.
Therefore, it is necessary to improve the structure of the oil storage tank, especially the oil extraction outlet and the oil extraction pipe in the prior art, so as to increase the practicability and convenience of the oil extraction pipe, reduce the amount of oil pollution generated by the oil tank during oil cleaning, reduce the amount of hazardous waste, and protect the environment.
SUMMERY OF THE UTILITY MODEL
In view of the above problem of the oil tank in the prior art, the utility model provides an oil storage tank with take out oil pipe, include:
a tank body including a tank top wall, a tank side wall, a tank bottom surface, and a tank base; an oil inlet is formed in the top wall of the tank; an oil extraction port is formed in the lower part of the side wall of the tank; a blow-down valve is arranged on the bottom surface of the tank; the bottom surface of the tank is arranged on the tank base through a bracket;
the oil extraction port comprises an oil extraction port connector and an oil extraction pipe; the oil extraction port joint is welded and assembled on the side wall of the tank; one end of the oil pumping pipe is positioned outside the tank body and is provided with a valve, and the other end of the oil pumping pipe extends into the tank body from the oil pumping port joint.
Preferably, the pipe head of one end of the oil pumping pipe extending into the tank body is arc-shaped.
Preferably, the arc of the pipe head corresponds to the radian of 1/6 pi to 1/4 pi.
Preferably, the lowest surface of the pipe head having an arc shape abuts against the bottom surface of the can.
Preferably, the pipe orifice of the pipe head is an oblique orifice.
Preferably, the oil extraction port joint seals and fixes the oil extraction pipe through a sealing ring or a flange.
Preferably, the oil pumping pipe is detachably designed, namely can be taken out from the oil pumping outlet joint.
The beneficial effects of the utility model reside in that, according to the utility model discloses an oil storage tank with take out oil pipe, it has improved the oil extraction mouth reaches take out oil pipe's structure, take out oil pipe for detachable design, be convenient for maintain to the resistance to pressure is strong, need not be at tank cavity installing support, can before clear jar take out oil pipe follows take out in the oil extraction mouth connects, can effectively reduce jar in-storage oil to reduce the greasy dirt volume when clearing jar, reached and reduced the dangerous waste volume, strengthened the purpose of oil recovery rate and environmental protection.

Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, which are illustrative of the present invention and are not intended to limit the present invention.
Referring to fig. 1 and 2, an oil storage tank with an oil pumping pipe according to the present invention includes: the tank comprises a tank body 1, wherein the tank body 1 comprises a tank top wall 2, a tank side wall 3, a tank bottom surface 4 and a tank base 5; an oil inlet 6 is formed in one side of the tank top wall 2 and used for injecting oil into the cavity of the tank body 1; an oil extraction port 8 is formed in the lower portion of the side wall 3 of the tank; the tank bottom surface 4 is provided with a drain valve 7 for discharging dirty oil in the oil storage tank; the tank floor 4 is mounted on the tank base 5 by means of a bracket.
The oil extraction port 8 comprises an oil extraction port connector 9 and an oil extraction pipe 10; the oil extraction port joint 9 is welded and assembled on the tank side wall 3; one end of the oil pumping pipe 10 is positioned outside the tank body 1 and is provided with a valve (not shown in the figure), and the other end of the oil pumping pipe 10 extends into the tank body 1 from the oil pumping port joint 9.
And a pipe head 11 at one end of the oil pumping pipe 10 extending into the tank body 1 is bent into an arc shape, and the radian corresponding to the arc shape is 1/6 pi to 1/4 pi. In other words, the arc of curvature of the pipe head 11 cannot be too large or too small. If the bending radian is too large, the oil is not easy to be taken out from the 8-oil extraction port; if the curvature is too small, the dirty oil in the tank 1 can be easily drawn out together.
In addition, the lowest part of the arc-shaped pipe head 11 is abutted to the tank bottom surface 4, so that a support is omitted from being erected on the tank bottom surface and used for supporting the oil pumping pipe. The contact point between the lowest part of the pipe head 11 and the tank bottom surface 4 can be used as a supporting point to support the oil pumping pipe 10 in the tank cavity of the tank body 1, so that the oil pumping pipe is not easy to shake or deform due to gravity and pressure.
The mouth of the pipe head is an inclined mouth which is designed to reduce the pressure and increase the oil pumping area when the oil pumping pipe 10 operates. In an embodiment according to the present invention, the distance between the pipe orifice and the tank bottom is 0.5 m, and in other embodiments, the pipe orifice can be adjusted adaptively according to the actual situation.
The oil pumping outlet joint 9 is sealed and fixed with the oil pumping pipe 10 through a sealing ring 12 or a flange; sealing ring 12 or flange are detachable design, when carrying out maintenance operations such as wash-tank, clear jar, the staff uses earlier take out oil pipe 10 takes out the oil in the oil storage tank, then dismantles sealing ring 12 or flange, because the radian of tube head 11 is less, and the application of force that carries out different angles is rotatory, can with take out oil pipe 10 smoothly follows take out in the oil extraction mouth 8, then open set up in on the tank bottom surface 4 blowoff valve 7 discharges sump oil.
The foregoing is a detailed description of representative embodiments of the invention. These detailed descriptions are not intended to limit the scope of the invention. Various modifications and equivalents of the invention can be made by those skilled in the art within the spirit and scope of the invention, and such modifications and equivalents should also be considered as falling within the scope of the invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
