1 is a schematic diagram showing a deposit removal apparatus 100 according to a first embodiment of the present invention.

According to this embodiment, as shown in Figure 1 and 2, as a device for removing the sediment of the ballast tank (ballast tank, 190) for ships floating in the ballast water to the outside, rotatable in the ballast tank 190 A plurality of first blades installed in the rotor body 110 such that the rotor body 110 rotates by the flow in the rotor body 110 and the ballast tank 190 according to the discharge of the ballast water. a plurality of second blades 125 installed on the first blade 120 and the rotor body 110 to generate a flow which floats the sediment in the ballast tank 190 as the rotor body 110 rotates. A precipitate removal device 100 is provided that includes.

According to the present embodiment as described above, the rotor body 110 can be rotated in a non-powered manner by using the flow in the ballast tank 190 generated when the ballast water is discharged without a separate driving means for rotating the rotor body 110. Therefore, the deposit removal device 100 can be simplified and compact, and the use and maintenance cost of the deposit removal device 100 can be significantly reduced.

In addition, by generating a flow to float the sediment in the ballast tank 190 by the second blade 125, the sediment can be effectively discharged to the outside of the ballast tank 190 to be accompanied by the ballast water in the suspended state. .

Hereinafter, each configuration will be described in more detail with reference to FIG. 1.

The rotor body 110 is rotatably coupled in the ballast tank 190. That is, as shown in Figure 1, the rotation center is rotatably coupled to the bottom of the ballast tank 190, the rotor body 110, the first blade 120 to be described later, according to the ballast water discharge As the load by the flow in the ballast tank 190 acts, it can rotate without any additional driving means.

At this time, a receiving hole 112 penetrating through the rotor body 110 is formed in the central portion of the rotor body 110. That is, as shown in Figure 1, the receiving hole 112 penetrating through the rotor body 110 is formed to face the bottom of the ballast tank 190. As the accommodation hole 112 is formed in the rotor body 110 as described above, the second blade 125 to be described later may be accommodated in the accommodation hole 112. This will be described again in the part presenting the second blade 125.

Meanwhile, a plurality of rotor bodies 110 may be disposed at the bottom of the ballast tank 190. As shown in FIG. 1, when the ballast water is discharged from the ballast tank 190 to the outside (hereinafter referred to as deballast), the outlet of the ballast tank 190 is connected to the ballast water in the ballast tank 190. Flow to 195 occurs. Thus, when a pair of rotor bodies 110 are rotatably coupled to the bottom of the ballast tank 190 so as to be symmetrical with each other based on the flow toward the outlet 195, each of the rotor bodies 110 is opposite to each other. Direction of rotation.

On the other hand, the first blade 120 is installed in the rotor body 110 so that the rotor body 110 rotates by the flow in the ballast tank 190 due to the discharge of the ballast water. As shown in FIG. 1, the rotor body 110 is a cylindrical member, and the plurality of first blades 120 are fixed along the rotational direction of the rotor body 110 on the outer circumferential surface of the rotor body 110. Each is arranged to have a gap.

As described above, at the time of deballasting, a flow toward the outlet 195, that is, a flow in the horizontal direction is generated in the ballast water inside the ballast tank 190. Therefore, when the plurality of first blades 120 are provided on the outer circumferential surface of the rotor body 110, the load due to the horizontal flow acts on the first blades 120, so that the linear motion of the flow is caused by the rotor body 110. Is converted into a rotational movement.

That is, when deballasting, before the ballast water in the ballast tank 190 reaches a certain level, due to the water pressure of the ballast water, there is a surplus energy in addition to the energy provided to the deballast, and this energy is horizontal of the ballast water. The rotor body 110 may be transmitted by the directional flow to rotate the rotor body 110. Thus, for example, if the total time required for deballast is 10 hours, the deposit removal device 100 may be operated for at least 7 hours using the above-mentioned spare energy.

As such, by rotating the rotor body 110 using the horizontal flow in the ballast tank 190, the sediment removal device 100 can be operated without power without the need for a separate driving means for driving the rotor body 110. As a result, the use and maintenance costs can be significantly reduced, and the deposit removal apparatus 100 can be simplified and compact.

In this case, a guide 130 is provided at the bottom of the ballast tank 190 in order to promote rotation of the rotor body 110 by flow in the ballast tank 190, that is, in a horizontal direction, due to the discharge of the ballast water. Is formed. That is, the guide 130 is formed in the ballast tank 190 so that the horizontal flow of the ballast water in the ballast tank 190 is guided to the first blade 120.

More specifically, as shown in FIG. 1, the pair of guides 130 concentrates the flow toward the outlet 195 of the ballast water on the first blade 120 formed on one side of the rotor body 110. In order to, toward the rotor body 110 side, the interval between them is arranged to narrow.

On the other hand, the second blade 125 is installed in the rotor body 110 so that a flow of floating the precipitate in the ballast tank 190 is generated by the rotation of the rotor body 110. As shown in FIG. 1, the plurality of second blades 125 extend from the rotation center of the rotor body 110 in the rotational radial direction, respectively, and are disposed at regular intervals along the rotation direction of the rotor body 110. .

As described above, the linear kinetic energy of the horizontal flow of the ballast water generated by the deballast is converted into the rotational kinetic energy of the rotor body 110 by the first blade 120. By installing the second blade 125 to generate the vertical flow in the rotor body 110 as described above, the ballast water adjacent to the second blade 125 flows in the vertical direction to deposit the bottom of the ballast tank 190. To float.

As described above, the vertical flow of the ballast water is generated by the non-powered rotation of the rotor main body 110 using the horizontal flow in the ballast tank 190, as shown in FIG. 1, the bottom of the ballast tank 190. The precipitate may be suspended, and thus, the suspended precipitate may be easily discharged to the outside by being accompanied by ballast water.

At this time, the installation angle of the second blade 125 is set to generate a flow toward the bottom of the ballast tank 190. That is, as shown in FIG. 1, the installation angle of the second blade 125 is set so that the flow of the ballast water is directed toward the bottom of the ballast tank 190.

In this way, according to the installation angle of the second blade 125, the flow of the ballast water to float the sediment is directed toward the bottom of the ballast tank 190, thereby more effectively removing the sediment at the bottom of the ballast tank 190, the ballast water Because it can be suspended inside, and can cause a continuous convection phenomenon by the ground effect (shown in Figure 1), the suspended sediment is not sedimented again, but more effectively accompanied by ballast water in the continuous suspended state Can be removed.

As shown in FIG. 1, an accommodating hole 112 is formed in the center portion of the rotor body 110, and the second blade 125 is accommodated in the accommodating hole 112. That is, a plurality of second blades 125 are formed to extend from the center of rotation of the rotor body 110 to the inner wall of the accommodation hole 112 in the rotational radial direction.

As described above, as the second blade 125 is accommodated in the accommodation hole 112 of the rotor body 110, the inner wall of the accommodation hole 112 guides the vertical flow generated by the second blade 125. Since it can function as, it is possible to float the precipitate more efficiently.

However, the second blade 125 is different from the above-described first embodiment in terms of its installation angle.

That is, the second blade 125 is installed in the rotor body 110 so as to be inclined as a whole with respect to the rotor body 110 to generate flow so as to face the bottom of the ballast tank 190 at an angle. That is, as shown in Figure 2, the installation angle of the second blade 125 is set so that the flow for floating the sediment facing the bottom of the ballast tank 190 obliquely.

In this way, the flow of floating sediment generated by the second blade 125 acts at an angle to the bottom of the ballast tank 190, thereby applying a shear force to the bottom of the ballast tank 190, so that the ballast tank ( 190) Sediments fixed on the bottom can be more effectively removed and suspended.
