Description

Technical Field [0001] The present invention relates to a ballast water filter device,

The present invention relates to a marine ballast water filter apparatus.

More particularly, the present invention relates to a method for filtering foreign matter and microorganisms contained in ship equilibrium water with high efficiency, and is capable of washing small filters and large filters even when foreign substances and microorganisms are filtered using small filters and large filters To a ship ballast water filter device.

In general, when the cargo is loaded on the ship, it may not be balanced before or after the ship. To this end, a ballast tank is provided in the inside of the vessel, and ballast water is introduced into or discharged from the ballast tank to solve the imbalance of the vessel due to the vessel loading.

On the other hand, as the international capacity is gradually increased and the marine transportation ratio is gradually increased, the ship is rapidly becoming larger and the amount of ballast water used in the ship is greatly increased.

As the amount of marine ballast water used in vessels increases, the number of cases of damage caused by marine ecosystems due to foreign marine species is also increasing. In order to solve these international environmental problems, In 2004, the International Convention for the Control and Management of Water and Sediments was adopted. The Convention will enter into force one year after the date on which more than 30 countries are joining and the ship's holdings in the participating countries are more than 35% of the world's ship holdings. As of September 7, 2016, Exceeding 35% of ship holdings.

As the Convention enters into force, it is obligatory to install a ship ballast water treatment system (BWTS) on the ship, which will prevent damage to ecosystem disturbance and harmful pathogens caused by ship ballast water.

On the other hand, a ship ballast water treatment apparatus installed on a ship is mainly subjected to a filtration method using a filter, followed by physical or chemical treatment such as electrolysis or ultraviolet ray treatment. Fig. 1 shows a conventional ballast water treatment apparatus Fig.

In the conventional ballast water treatment apparatus, it is configured to be capable of driving to automatically clean foreign substances deposited on the filter during use.

That is, when the ship ballast water treatment apparatus shown in the drawing is in the normal filtration operation, the ballast water flows into the inflow water line 1, flows through the filter installed in the housing 2, If the filter is clogged due to a large amount of foreign matter deposited on the filter, the cleaning operation is started by sensing the clogging of the filter. That is, during the washing operation, the ballast water is moved from the treated water line 4 to the washing line 5, thereby removing foreign matters stuck in the filter, thereby enabling continuous ballast water treatment.

However, when the concentration of the solid matter among the foreign substances entering the filter is increased, the cleaning speed can not keep up with the filtration rate, and the sediment foreign matter gradually increases. As a result, There is a problem that the processing apparatus can become inoperable.

FIG. 9A is a view showing an embodiment of a brush of a filtering device for treating ship equilibrium water according to the present invention, and FIG. 9B is a view showing another embodiment of a brush of a filtering device for treating ship equilibrating water according to the present invention.

9A and 9B, one or a plurality of brushes 560 may be provided at the outer periphery of the rotating shaft 520 of the marine ballast water filter device of the present invention to contact the inner periphery of the large filter 410 have.

At this time, the brush 560 may be configured such that the density of bristles gradually increases from the upper portion to the lower portion. This is because the foreign matter deposited on the inner circumferential edge of the large filter 410 relatively increases the density of the bristles ) Is deposited on the lower part of the surface of the substrate.

According to an embodiment of the present invention, the brushes 560 may include at least two or more brushes 560 that are symmetrical about the rotation axis 520, respectively.

For example, when the brush 560 is provided at a position symmetrical with respect to the brush 560, the brush 560 contacts the inner circumference of the dust filter 410 according to the rotation of the rotating shaft 520, Each of the two brushes provided to be symmetrical with respect to the rotation axis 520 is configured to be in contact with the inner circumferential edge of the filter 410 so that the rotation axis 520 is rotated one rotation The inner periphery of the large filter 410 may be configured to be in contact with each of the two brushes 560, thereby improving cleaning efficiency.

According to another embodiment of the present invention, the brush 560 may include at least two or more brushes 560, each of which may be disposed at a position different from the rotation axis 520. That is, when the brushes 560 are composed of two brushes 560, the two brushes 560 are provided on the upper and lower portions of the rotation shaft 520, respectively.

For example, when the brushes 560 are provided at the upper and lower portions of the rotating shaft 520, the brushes 560 are brought into contact with the inner peripheral edge of the large filter 410 in accordance with the rotation of the rotating shaft 520, When cleaning the large filter 410, the two brushes 560 are configured to contact and clean the upper and lower portions of the large filter 410, respectively, The resistance generated by the brushes 560 is dispersed in the brushes 560, so that a load can be prevented from being generated in the rotary motor 510 that rotates the rotary shaft 520.

As described above, according to the present invention, it is possible to filter foreign matter and microorganisms contained in ship equilibrium water with high efficiency, and to clean the small filter and the large filter even while filtering the foreign matter and microorganisms by using the small filter and the large filter .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It can be seen that branch substitution, modification and modification are possible.
