Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid injection device suitable for use in removing sludge O accumulated inside a floating roof type oil tank, for example.

Tanks that store crude oil and other oils accumulate solid oil sludge inside them over a long period of time. This sludge must be removed because it reduces the internal volume of the tank or becomes a hindrance when maintaining and inspecting the tank.

During sludge removal processing, if the amount of sludge deposited is small, or if the sludge is deposited below the height of the manhole at the bottom of the side wall of the tank, open the round manhole to remove the oil from inside the tank. However, a sludge removal device is carried inside the manhole and removed. However, if the amount of accumulated sludge exceeds the height of the manhole, the manhole cannot be opened, making sludge removal difficult.

In such cases, the most common method is to heat the sludge to a temperature of 7 mA or more using various means to fluidize the sludge, then suck the t% fluidized sudge with a bonder and discharge it from the tank. ing.

However, near t and Jl, the internal volume is 1 (140Q -ISO,
There is a large oil tank that is as large as QOOWIK, and sludge may accumulate inside 2o, ooo~so, oooKt, so this huge Wk□x kukuji is Re1l! [
(S.

It takes a huge amount of heat and heating time to heat up to 70C or higher. Therefore, not only is there a huge economic loss, but the work period is also long, and the inside of the tank cannot be used for that purpose.

Moreover, it cannot be used in the absence of a heating source.

Also, insert the flexible bayder into the oil tank.

A method for disintegrating and removing accumulated sludge by means of laminar pressure oil spouted from the tip of a skeletal pike is known from Japanese Patent Application Laid-open No. 140160/1983.

However, this method requires an extremely long working period because it involves the injection of oil from a local pipe, and cannot meet the demand for reliably treating OX sludge all over the place in a short period of time. In addition, conventional devices generally have the disadvantage that they cannot effectively remove any sludge that adheres to and accumulates on the lower surface of the floating roof of a floating roof type oil tank.

In view of these circumstances, the present invention was made with the aim of providing a sludge that efficiently removes the sludge adhering to the inside of the oil tank including the underside of the floating roof. It is tubular and can be inserted through some of the many pillar openings provided on the floating roof. After insertion, the bending tube and swinging injection tube are bent to form an L-shaped liquid jet. The oil tank is made into a pipe, and the entire interior of the oil tank can be cleaned by spraying liquid while rotating the pipe.

The present invention will now be described with reference to a complete implementation.

The liquid injection device according to the present invention has four fixed parts extending from the control box I in the T direction, and a short rotary cylinder rotatably supported at the lower end of the fixed cylinder. 3. 9, this injection becomes a bent state when rotated relative to the rotation IIIJ, and a bent state becomes a bent state when rotated relative to the bent point. @S
The lower end of the is a spout.

To explain the connection of each part, a female thread is cut on the inner surface of the lower end of the first piece, and a connection/sleeve is attached to this female thread. The upper end O ground screw is screwed together, and the sleeve is integrated into a uniform piece. , An annular bottle groove l is carved in this sleeve f O side, and the bottle groove tK is inserted from the outside of the rotary cylinder J. Therefore, the rotating cylinder 3 is connected to the fixed cylinder. It is rotatable relative to the

Rotation@soP'' end is, for example, 45!l in the axial direction
The slope is 9. This end face part io is
On the other hand, if you move in the same axial direction at the upper end of Orisaki San, it is 45!
The inclined end portions 11 and 11 are in contact with each other. The internal teeth are fixed to the slanted end face /l on the bending side, forming a perfect circle! ! ! 111141/KO
It encloses and rotatably supports the rotary cylinder J and the bent ginseng. Therefore, when the rotary tube J and the bent tube are placed in a straight line and a relative rotation is applied between the two tubes, the bent tube is bent due to the inclination of the end surface 10, //, and the gap between the two tubes is When the rotation angle reaches 180°, both cylinders form a single character shape. The connecting portion between the bent wN cylinder and the oscillating injection cylinder j is similar to that between the rotary cylinder 3' and the bent cylinder. That is, the slanted end surface portion of the folding IF end is in close contact with the slanted end surface tS of the swinging jet envelope S, and both are rotatably held by the joint 74. 'Next, the bending mechanism for bending the folded paper relative to the rotation 1117 will be explained. Fixed mco and rotation 11113
The upper end of the shaft reaches the control box I, and the lower end is rotatably supported by the Naport arm J/ protruding from the inner surface of the rotor #113. A bevel gear that meshes with the internal gear I is fixed to the lower end of wlJJ.

In the same way, a bevel gear is fixed to the middle part of this driving inner cylinder, and this bevel gear supports the rod 1 in the fixed cylinder -〇operation box j so as to be retractable. The other rotating line 3, which can engage with the core, is integrally provided with a driven inner shaft via a plurality of radial arms U. This driven inner core is located at the outer four sides of the driving inner cylinder n, and a part of it is 18 mm in the local direction (lateral direction).

The rotating rod roof is located in the shaft hole 3j of the bevel gear and in the drive @J
The drive mechanism in the Yuma-9, which is guided into the roll box I and rotated by the drive mechanism in the cough box, is connected to the armpit box separately from the small bevel gear 27 of the operation box j. The paper is rotated by a drive mechanism inside the machine.

The two-part movement mechanism is driven by a turbine 3) provided in the pressure fluid supply path 34 to the fixed cylinder.The device having the above structure can, for example, move the inside of a floating roof type oil tank and the f of the floating roof. To discharge and dispose of the slats (C) that have accumulated on the surface, the fixed part C, the bent chisel and the swinging injection tube S are shaped into straight tubes and inserted into the support opening d provided in the floating roof. Next, the small bevel gear core of the operation box j is pushed in together with the rod holder, which engages with the bevel gear t and rotates the small bevel gear #II core. Then, inside the prime mover lol
When the in rotates, the bevel gear rotates as one.

@Jan rotates relative to $11JK,)
'ru. When the driving inner cylinder n rotates 180 degrees from the state where the rotary cylinder J and the folding key are in a straight tube shape, the bending cylinder m becomes perpendicular to the rotation 1lIJ due to the action of the inclined end face 10. This will result in a reversal. In this operation, the lever protrudes from the driving inner m- and the round pin 3/ moves within the pin groove X of the driven inner cylinder tip, so that the driven inner cylinder tip and the rotating cylinder J do not rotate.

After the above setting is completed, pull the small bevel gear core to remove the bevel gear gear and O#i mesh.

〇 Bin J/ is rounded reaching the end of pin #X, inside the isa drive @
When U rotates, the driven inner cylinder tip also rotates, and as a result, the rotating part 111J rotates with respect to the fixed part K, and the bent part M remains bent at right angles to the rotating cylinder 311C and is fixed. Rotate around the tube. In other words, the bent barrel rotates by rotating 113 and 4 Klim by the bevel gear C and the internal gear I, maintaining a rounded and bent state with no relative rotation between it and the rotation 113. The rotation of the rotating rod is 7 lexipul joint 3J.
Finally, it is transmitted to the swinging injection cylinder S via the tortoise fixed rod I3. Then, this injection cylinder S and the bent part are connected by the inclined end face parts 1 and 1, and a relative rotation occurs between the two cylinders, so the oscillating injection @S is connected to the bent part 11. The motion repeats by turning to a right angle and then to a straight line again. Therefore, when viewed as a whole, the series of cylinders rotates repeatedly in a 5-shape and a 0-shape, and the cleaning liquid is spouted from the spouting mark at the tip of the swinging injection cylinder S.
This jetted cleaning liquid will cause the inside of the tank 1 to become wet, especially the floating rih*h.
The sludge C adhering to the tank collapses, dissolves, and becomes fluidized.The sludge C is then fluidized and can be discharged out of the tank using a tank.

After the above sludge removal work is completed, stop spraying the cleaning liquid and make each part straight and remove the color from the support and opening d.

The oscillating injection cylinder S becomes straight due to its own weight, but the bent cylinder can be made straight by using a small bevel gear core and a reverse O operation as described above.

In the above embodiment, the rotation 1IIJ, the folding angle, and the swinging jet smog oblique end portion 10°// and l reference, /j are inclined 411” with respect to the shaft embroidery side. These rounded bodies are folded at 90 degrees, but it is clear that the folding angle f of these cylinders will change if the inclination angle is adjusted.Also, the internal members of each key body are exposed to cleaning liquid t. )RIkWJ
It is desirable to round off the product to make it as small as possible.

Good bevel gear.

It is advisable to make holes in the potato within a range that does not impair its strength.

In summary, according to the liquid ejecting apparatus of the present invention.

While rotating the series of key bodies by bending them in two stages, liquid such as cleaning liquid can be sprayed from the spout at the tip. In 41, the Orisaki was kept in a bent state for one roll casting, and the swinging injection cylinder was rolled to eject the frL body, and the inner surface of the floating ala of the oil tank was affected. Can be washed separately.

Since the series of keys can be made straight when not in use, they can be easily inserted into and removed from the column holes of the edema machine OS, and therefore have practical value for spraying cleaning liquid for sludge treatment of oil tanks. is high.
