Description

[0001] Oil heating drum of ship [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an oil heating drum for ships, and more particularly, to an oil heating drum for heating oil stored in an oil tank of a ship to a predetermined temperature, .

Generally, in an oil tank of a ship carrying an oil such as a tanker, there is provided a drum type oil heating device for keeping the viscosity constant in the case of oil such as bunker oil.

The oil tank is located at the lower part of the ship and maintains a relatively low temperature due to the influence of seawater. In winter, in the case of winter, Antarctica and North Pole, the temperature is cooled by the subzero temperature and the viscosity becomes very high.

A drum-type oil heating apparatus has been proposed in order to maintain the viscosity of the oil in the oil tank of the ship at a constant level since the use of the oil tank becomes unstable as the viscosity becomes high.

Conventional oil heating drums include a hollow cylindrical body, side slats hermetically sealing both openings of the body, and oil supplied to both sides of the side plate so that the oil filled in the tank is connected to the outside. A heating medium inlet pipe connected to the inside of the body to allow the heating medium to flow therein, and a heating medium discharging pipe for discharging the heating medium introduced into the inside of the body for circulating the outside.

The heat medium is mainly supplied to the inside of the cylindrical body having the inlet which is opened at both sides by the side blowing at the high temperature steam, and flows into the inside of the oil pipes or functions to lower the viscosity constantly by heating the oil located at the outside .

The cylindrical body and the oil pipes of such conventional oil heating drums are joined together by welding in the joints of both side plates.

When the cylindrical body and the oil pipes are welded and fixed to the side plate, there is a disadvantage that the manufacturing cost is increased due to the complicated and highly skilled work and a lot of working time.

In addition, due to the nature of the product, sudden temperature changes occur due to the effect of seawater having a very low temperature and the supply of high-temperature heat medium. Due to the nature of the welding, the expansion and contraction are repeated due to the rapid temperature change. Cracks can not be avoided.

If such a rapid temperature change is repeated, if cracks are generated, steam, which is a heat medium, leaks and oil and moisture are mixed to lower the purity of the oil, thereby deteriorating the thermal efficiency or seriously losing the value of the product as oil It was.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in the drawings, the drum type oil heating apparatus according to the present invention includes a cylindrical body 10, two side plates 20, an oil pipe 30, a heating medium inlet pipe 40 and a heating medium outlet pipe 50 .

The cylindrical body 10 is constructed such that the entirety of the cylindrical body 10 is formed in a drum shape by securing the two side plates 20 made of a disk-shaped body with both side open.

The side plate 20 is provided with a plurality of oil pipes 30 by drilling the pipe assembly holes 25 at the same position.

The openings of both sides of the cylindrical body 10 are blocked by the side plates 20 and the oil pipes 30 are installed in the airtight state between the side plates 20, 10).

In this sealed space, the heating medium is filled through the heating medium inlet pipe 40 connected to the side plate 20, and then discharged to the heating medium discharge pipe 50 and supplied to the heater, so that the heating medium is circulated from the heater to the drum type oil heating apparatus You can.

The heating medium mainly uses high temperature steam, and functions to maintain the viscosity constant by heating the oil introduced into the oil pipes 30 or located outside the cylindrical body 10.

The heating medium inlet pipe 40 and the heating medium discharge pipe 50 are connected to each other through nipples assembled to the side wall of the side plate 20 so that steam heated by a heater such as a boiler (not shown) The oil pipes 30 and the outside of the body 10 are heated and then circulated to the heater again.

The most important constitutional feature of the present invention is to combine the parts of the parts with each other without the need of welding, simply and firmly without fear of cracking.

That is, a circular groove 21 is formed along the circumferential surface of the side plate 20 having a predetermined thickness, and an O-ring 22 having an O-shaped cross section is formed in the ring groove 21 in a forced fitting manner .

The fitting portion 11 for determining the position in a state in which the side plate 20 is fitted inward is formed at both openings of the hollow cylindrical body 10 with a diameter larger than the central inner diameter.

The inner diameter of the fitting portion 11 is machined to a dimension corresponding to the outer diameter of the side plate 20. [

At both ends of the cylindrical body 10, the fold-over portion 12 is integrally formed along the circumference.

The inner diameter of the finishing bend portion 12 is larger than the diameter of the fitting portion 11 and is formed into a cylindrical shape with a relatively small thickness. When the side plate 20 is positioned in the fitting portion 11, 20 are pressed to be bent along the circumference of the outer surface of the side plate 20 to thereby tightly fix the side plate 20 to the finish folding portion 12. [

Therefore, the side plate 20 positioned in the fitting portion 11 is fixed to the step portion due to the difference in diameter between the inner side portions of the fitting portion 11 so as not to flow to the inner side center portion, and the outer side surface is fixed by the finishing bent portion 12 So that it can be assembled perfectly and firmly. (Figs. 6 and 7)

Since the O-ring 22 provided along the circumferential surface of the side plate 20 is in close contact with the inner diameter of the fitting portion 11, the airtightness can be maintained and the heating medium, which is filled in the inner space of the cylindrical body 10, It can be completely blocked.

The side plate 20 is assembled to the cylindrical body 10 by folding the receiving groove 26 by a thickness and a bending length at the outer periphery of the side plate 20 so that the outer plate 20 It is good to be able to finish nicely.

7, a Teflon gasket 70 may be further installed between the outer surface of the side plate 20 and the finishing fold 12 of the cylindrical body 10 in terms of airtightness.

In this structure, the cylindrical body 10 and the side plates 20 are closely fixed to each other, and the side plates 20 and the oil pipes 30 are firmly assembled in a separate process while keeping the airtightness .

That is, the pipe assembling holes 25 are drilled at the same position in consideration of the assembling position of the oil pipes 30 on the both side plates 20.

The oil pipes 30 are formed with an insertion portion 31 with a diameter corresponding to the inner diameter of the pipe assembly hole 25 and the O-ring 33 is formed in the O- Respectively.

At both ends of the insertion portion 31 of the oil pipe 30, the expansion finishing portion 34 is further extended along the circumference.

The expansion finishing portion 34 is formed so that its cross-sectional thickness is relatively thinly formed, and is pressed and deformed by a tool to be plastically deformed and expanded.

The cylindrical body 10 and the side plate 20 including the oil pipe 30 are made of a metal material having a high thermal conductivity and being capable of plastic working.

Therefore, the oil pipe 30 is inserted into the pipe assembly hole 25 of the side plate 20, and then the expansion finishing portion 34 is expanded as shown in FIG. 6, The plurality of oil pipes 30 can be fixed to the side plate 20 by the same method.

Since the O-ring 33 installed along the circumferential surface of the insertion portion 31 of the oil pipe 30 is in close contact with the inner diameter of the tube assembly hole 25, airtightness can be maintained, It is possible to completely block the case where the filled heat medium leaks through the clearance between the oil pipe 30 and the side plate 20.

7, a Teflon gasket 70 may be further installed between the outer surface of the side plate 20 and the expansion finishing portion 34 of the oil pipe 30 in terms of airtightness.

According to the oil heating drum structure of the present invention, since there is no welded portion at the position where the components are fastened, there is almost no possibility of cracking due to shrinkage due to rapid thermal deformation and repetition of the expansion process.

In addition, the assembly process is relatively easy and robust, thereby lowering the manufacturing cost and significantly improving the durability of the product.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of illustration, will be.

The present invention is applied to the field of marine oil heating drums. Especially, it is applied to the technology that can maintain the durability and safely protect the oil because each part can be kept firm and tight without welding.
