BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for removing air bubbles generated during a process of transferring crude oil stored in a cooling tank of a ranch to a transportation vehicle, and a collecting system using the same.

Generally, the process of producing milk as a product is as follows.

First, milk is slaughtered in a cow in the ranch, and crude milk of salted milk is collected and stored in a refrigerator tank provided in the ranch.

The transported vehicles will be collected and collected, and processed milk will be processed to complete the milk product.

Here, since the unit price of crude oil is high, accurate amount of crude oil should be measured at the time of collection.

However, crude oil stored in the refrigerator tanks of each ranch is sent to a measuring instrument that detects the flow rate through the pump and hose attached to the transportation vehicle. At this time, due to the high flow rate, air is mixed into the crude oil, It is not possible to measure, especially, due to bubbles, an error occurs in the measuring instrument, and furthermore, a trouble occurs in the measuring instrument.

In order to solve this problem, an air remover has conventionally been used to remove air bubbles generated during the collection of crude oil. However, a large amount of air bubbles were generated in the collection process, and it took a long time to remove air bubbles, and the collection time became very slow. On the other hand, when the collection time is shortened, the bubbles are mixed and collected, so that the accurate amount of crude oil can not be measured.

Further, when the crude oil flows into the air eliminator, there is a phenomenon that it is biased to one side, so that the pressure change inside the air eliminator is severe and the flow is unstable and a large amount of bubbles are generated.

The inflow section 12 is a means for supplying crude oil to the inside of the main body 11 and includes an inflow pipe 121 and a charging section 122.

The inlet pipe 121 is substantially cylindrical and is provided to penetrate the side wall of the main body 11 and is provided on the side wall of the main body 11 toward the center line of the main body 11.

The inlet portion 122 is substantially cylindrical and has an upper end and a lower end opened and an upper end opening corresponding to the outer diameter of the housing 151. A lower end opening is formed to be larger than an upper end opening, And is fixed to the housing 151.

In addition, the charging unit 122 may have a semispherical shape or a truncated conical shape at the upper end of the charging unit 122 so that the crude oil is not accumulated at the upper end.

Accordingly, when the crude oil flows into the inflow pipe 121, it is discharged through the lower end opening of the inflow portion 122. That is, the crude oil introduced into the inflow pipe 121 through the lower end opening of the charging unit 122 and the housing 151 is discharged, and a part of the discharged crude oil falls down freely while the other part rides down the circumference of the housing 151 Lt; / RTI >

The guiding part 13 moves the bubbles contained in the crude oil to the inside of the housing 151 while moving the crude oil discharged through the charging part 122 toward the inner wall of the main body 11, And a second guide 132.

The first guide 131 is disposed in a substantially truncated conical shape below the charging part 122 and is fitted and fixed to the housing 151.

The first guide 131 is formed to have an outer diameter smaller than the inner diameter of the main body 11 so that a gap is formed between the first guide 131 and the main body 11 and a gap of about 3 mm to 50 mm can be formed .

In addition, the first guide 131 may be formed as an upwardly inclined or concave round, and an upper end around the first guide 131 may be formed as a downwardly inclined or convex round.

Accordingly, the crude oil discharged through the discharge portion 111 moves toward the inner wall of the main body 11 on the upper surface of the first guide 131, and the moved crude oil flows down the inner wall of the main body 11 downward.

Since the discharged crude oil can flow smoothly through the round formed at the upper end of the first guide 131 and the circumference of the first guide 131 is rounded, the crude oil flowing through the first guide 131, It is possible to mitigate the collision against the inner wall of the casing 11, thereby preventing the generation of bubbles.

The bottom surface of the second guide 132 corresponds to the bottom of the main body 11 and is disposed under the first guide 131 and fixed to the housing 151 .

The second guide 132 is spaced apart from the bottom of the first guide 131 and the main body 11 and the outer diameter of the second guide 132 is smaller than the outer diameter of the first guide 131 And a slit S which is inclined upward is formed between the first guide 131 and the second guide 132.

Further, the slit S is communicated with the housing 151.

The bubble attenuation section 14 is composed of a plurality of blades and is disposed radially above the first guide 131 and fixedly attached to the upper surface of the first guide 131.

At this time, the gap between the blades corresponding to the region where the crude oil is dropped may be formed to be about 1 mm to 10 mm.

Accordingly, the crude oil discharged through the input portion 122 is separated and moved by the plurality of blades.

On the other hand, as shown in FIG. 4, the bubble attenuation portion 14a may be formed by bending the blade so as to form a whirl.

Accordingly, when the crude oil moves along the blades, the crude oil flows downward while moving in a direction substantially contacting the inner wall of the main body 11, thereby preventing the crude oil from colliding with the inner wall of the main body 11 and flowing smoothly.

Therefore, by moving the crude oil smoothly, it is possible to prevent the occurrence of bubbles during the movement of the crude oil, and further, the collection time of the crude oil can be shortened.

As shown in FIGS. 5 and 6, the blade of the bubble attenuation portion 14b may be formed to be pointed toward the upper end, or may have a tip end formed of a tetrahedron.

7 and 8, the blades of the bubble attenuation portion 14c may be rounded at the tip and be sharp at the top.

Accordingly, when the crude oil falling from the top of the bubble attenuation parts 14b and 14c collides with the blades, the crude oil is naturally split and flows into the blades, thereby preventing bubbles from being generated during the collision.

The blades of the bubble attenuation sections 14, 14a, 14b and 14c may be arranged between the blades having different lengths in order to make the interval between the blades to be as maximum as possible.

The filter net 17 filters the foreign substances contained in the crude oil and is formed into a substantially cylindrical shape and inserted into the lower portion of the housing 151.

The crude oil moving between the second guide 132 and the bottom of the main body 11 passes through the lower end opening of the housing 151 and is discharged through the discharge net 111 to the outside of the main body 11 via the filter net 17 do. That is, the filter net 17 filters the foreign substances contained in the crude oil before the crude oil is discharged out of the main body 11.

Here, the filter net 17 is described as being inserted into the lower end of the housing 151, but it may also be formed directly below the housing 151.
