Description

Anti-settling self-cleaning device for petroleum product storage tank

Technical field

The present invention relates to oil product storage tank with anti-heavy cleaning technique, relate to a kind of anti-settling self-cleaning device for petroleum product storage tank in particular.

Background technology

How crude oil, heavy oil storage tank install agitator at the storage tank sidewall for preventing sedimentation, adopt this type of agitator technology, and the deficiency of several respects is arranged:

A) agitator is installed in tank wall, and agitator stretches into jar interior axial length and is not more than 2 meters, and with respect to tens meters to tens meters of tank diameter, depth of interaction is not enough;

B) action principle of agitator is to form eddy current by oil product in the storage tank, drives the oil product motion, stirs anti-heavy purpose thereby play;

C) though agitator varies in size according to the storage tank specification, the model of varying number different capacity is installed, by forming the eddy current indirectly-acting, ability to function is limited, poor effect;

D) adopt the agitator technology of installing, except that the investment of agitator in-house facility, also need expenses such as distribution, circuit, operation, maintenance, integrated cost is higher.

E) though existing storage tank has been installed agitator, a large amount of heavy collection still appear, need regularly clean to oil tank, cause cleaning, operating cost higher.

For preventing that heavy knot from appearring in jar interior oil product, in the long-term use of oil tank, also have other some technology to use, comprise that tank deck oil-feed, oil inlet pipe are introduced the oil tank center, flowline is arranged on the oiler offside or causes offside, but all in all be local, effect is undesirable, to reducing the heavy knot of oil tank DeGrain.

Summary of the invention

The object of the present invention is to provide a kind of device that oil product power cleans the storage automatically in the oil inlet pipe that utilizes.

For achieving the above object, the present invention includes oil pipe and connect cavity, the female pipe of rotation, a plurality of atomizers, the in-line gears group, impeller, worm screw, oil pipe connects cavity and is connected with oil inlet pipe, vertically place the bottom centre position of oil tank, utilize the oil product power of oil inlet pipe, drive oil pipe and connect the interior impeller rotation of cavity, by the worm screw that is connected with impeller, the in-line gears group, the rotation of impeller is delivered to the female pipe of rotation, a plurality of atomizers are welded on the female pipe of rotation by different angle, and described atomizer inside is provided with the nozzle rotor, make oil product from jet hole 360 degree rotation ejections, tank bottom is carried out comprehensive injection, and active force is strong, do not stay the dead angle.

The anti-settling self-cleaning device for petroleum product storage tank that adopts technique scheme to realize has the following advantages:

1. anti-heavy cleaning performance is good, prevents sinking cleaning to storage tank is comprehensive, does not stay the dead angle;

2. flow process is simple, need not add any flow process;

3. investment cost is low

The specific embodiment

Fig. 1 structure outside drawing of the present invention

Fig. 2 structure of the present invention is partly cutd open figure

Fig. 3 nozzle of the present invention partly cuts open figure

The invention will be further described below in conjunction with accompanying drawing:

The present invention includes oil pipe and connect cavity 1, the female pipe 2 of rotation, in-line gears group 3, impeller 4, worm screw 5,

atomizer

6,7,8,9; The present invention vertically places the bottom centre position of oil tank, and the bottom that oil pipe connects cavity 1 is connected with the oil tank oil inlet pipe, and its bore matches.

Described oil pipe connects the female pipe of cavity 1, rotation 2 and is tightly connected by the bearing mode, can rotate each other, connects the stator terminal of cavity 1 as bearing, the female pipe of rotation 2 rotor-end as bearing.

Described oil pipe connects cavity 1 an inner side and is provided with impeller 4, the end of worm screw 5 is as the rotating shaft of impeller 4, fix in succession with impeller 4, the other end extends oil pipe and connects cavity 1, in-line gears group 3 vertically is fixed on oil pipe by two gear stands 10,11 and connects cavity 1 outside, the bigger gear in its underpart is that the less gear in worm gear 12, top is a driving gear 13, the mutual interlock of tooth of worm gear 12 and worm screw 5 elongated ends.

The bottom extension of the female pipe 2 of described rotation is provided with a circle driven gear 14, the mutual interlock of tooth of driven gear 14 and driving gear 13; The tube wall arranged outside of the female pipe 2 of rotation has 4

atomizers

6,7,8,9, the angle that described

atomizer

6,7,8,9 and tube wall form has nothing in common with each other, make to have nothing in common with each other, thereby reach the demand of the covering oil pipe of equalization from the lift of the oil product of

atomizer

6,7,8,9 ejections.

Described oil pipe oil inlet pipe, oil pipe connection cavity 1, rotation parent 2,

atomizer

6,7,8,9 each part are tightly connected, and form a plurality of oil product paths.

When practice of construction, according to the size of oil tank, select to connect the number of atomizer, but the atomizer number that connects should be not less than 4.Calculate the angle of each atomizer and tank skin according to the number of the diameter of oil tank and atomizer, but the angle of each atomizer and rotation parent tube wall has nothing in common with each other.
