5, the grinder unit 100 includes a rotating shaft 130 which is elongated in one direction and penetrates the grinder unit 100 along the longitudinal direction thereof.

The plurality of grinders 100g, 100h, and 100i are positioned on the rotary shaft 130 and rotate in accordance with the rotation of the rotary shaft 130. [ At this time, as described above, due to the rotation of the grinders 100g, 100h and 100i, the aquatic organisms contained in the ballast water flowing into the grinder part 100 are killed.

The grinder portion 100 also has lid portions 101a, 101b, and 101c corresponding to the number of grinders for replacing the grinders 100g, 100h, and 100i.

The motor 120 connected to the lid part 101a of the grinder part 100 receives the ballast water inflow detection signal output from the inlet valve 40 and generates power.

The medicine storage unit 400 stores a cleaning agent for cleaning foreign substances adhering to the grinder 110.

The grinder part 100 having such a structure is preferably formed to have a larger diameter than the ship ballast water inflow pipe 12. [

Referring to FIG. 1 again, a ship ballast water treatment apparatus having a grinder according to an embodiment of the present invention will be described. A second flow meter 22 is provided in the grinder unit 100 to remove aquatic life- The sterilized vessel equilibrium water is received and the flow rate is measured and the measured flow rate is output.

The power supply and control unit 300 applies power to the motor 120 of the grinder unit 100 and supplies power from the inlet valve 40 and the first and second flow meters 21 and 22 and the hydraulic system 30, The ballast water inflow, the ballast water flow rate, and the hydraulic pressure sensing signals of the ship ballast water, respectively.

The power and control unit 300 determines whether or not the ballast water inflow from the inlet valve 40, the flow rate of the ballast water received from the first and second flow meters 21 and 22, Generates a motor drive control signal for controlling the drive of the motor 120 according to the hydraulic pressure of the ship ballast water delivered thereto, and transmits the motor drive control signal to the motor 120.

The motor drive control signal may be a signal for controlling the motor to drive the motor, a signal for controlling not to drive the motor, or a signal for controlling the drive speed of the motor.

The power supply and control unit 300 generates a control signal for controlling the motor 120 not to be driven when the ballast water inflow detection signal is not received from the inlet valve 40, When the ship ballast water inflow detection signal is received from the ship, a control signal for controlling the motor 120 to be driven is generated.

In another example, the power and control unit 300 generates a signal for controlling the motor 120 to be driven slowly when the flow rate of the ballast water received from the first flow meter 21 is small, 120 to drive only some of the motors 120.

The power supply and control unit 300 may control the driving of the motor 120 so that the pressure inside the grinder unit 100 is maintained at 5 bar.

The first ballast water discharging pipe 13 receives the ballast water measured in the second flow meter 22, that is, the ballast water sterilized in the grinder 100, and flows in one direction. The tank 200 stores the sterilized ship ballast water transmitted from the first ship ballast water discharge pipe 13.

The oxidizing agent injecting section injects a small amount of the oxidizing agent into the ballast water flowing through the first ship equilateral water discharging pipe 13, It is recommended that additional aquatic organisms in the ship ballast water not yet destroyed are killed.

In another example, an electrolytic apparatus is further included, and the ballast water flowing through the first ballast water discharging pipe 13 is electrolyzed so that the water in the ballast water in the ballast water that has not yet been killed in the grinder unit 100 Can be additionally killed.

When the oxidizing agent injecting unit or the electrolyzing apparatus is constructed as described above, since the oxidizing substance is generated in the ballast water, it may further include a neutralizing agent injecting unit for neutralizing the generated oxidizing substance.

At this time, since the ship ballast water flowing into the oxidizing agent injecting section or the electrolytic apparatus is the ship ballast water primarily treated by the grinder section 100, the oxidizing agent injecting section injects a small amount of the oxidizing agent into the ballast water, The intensity of the current generated in the decomposition device is weakly generated. As a result, the size of the oxidizing agent injecting unit or the electrolytic apparatus can be reduced, and thus the size of the ship ballast water treating apparatus can be reduced.

Also, since the oxidizing agent generated by the oxidizing agent injecting unit or the electrolyzing unit is small, the neutralizing agent injecting unit can neutralize the neutralizing chemical injecting unit by injecting only a small amount of neutralizing chemicals into the ballast water, .

Furthermore, by providing the ultraviolet ray irradiating unit for irradiating ultraviolet rays (UV) to the ballast water flowing through the first ballast water discharging pipe 13, it is possible to further add the aquatic organisms in the ballast water that have not been killed in the grinder unit 100 It is good to die.

The concentration and the weight of the oxidizing agent or the neutralizing agent injected from the oxidizing agent injecting unit or the neutralizing agent injecting unit may be 1/5 to 1/5 of the concentration and weight of the oxidizing agent or neutralizing agent injected from the existing ship equilibrating water treating apparatus, 10, the size of the oxidizing agent injecting part or the neutralizing agent injecting part can be miniaturized, and the ultraviolet ray irradiation amount of the ultraviolet ray irradiating part can be reduced to 20 to 80% of the irradiation amount of ultraviolet ray irradiated by the conventional ship ballast water treating device Since only the ultraviolet rays are irradiated, the maintenance efficiency of the ultraviolet lamp is improved.

The second ballast water discharge pipe 14 is a pipe for discharging the ballast water stored in the ballast tank 300 to the outside of the ship.

Since the ship ballast water treatment apparatus having the grinder according to the embodiment of the present invention has such a structure, the aquatic organisms in the ship ballast water are crushed and physically sterilized according to the rotation of the grinder 110.

Therefore, it is possible to sterilize ship equilibrium water even if chemicals are not applied for the sterilization of ship equilibrium water. Therefore, it is possible to solve the danger of handling and disinfection by-products caused by sterilization of ship equilibrium water by using chemicals. Can be effective.

Next, the operation of the ship ballast water treatment apparatus having a grinder according to one embodiment of the present invention will be described with reference to Figs. 1 to 3. Fig.

First, the ballast water flowing through the ballast water inflow pipe 11 passes through the inlet valve 40 and flows along the ballast water inflow pipe 12.

At this time, the flow rate measured by the first flow meter 21 and the hydraulic pressure measured by the hydraulic meter 30 are transmitted to the power source and the controller 300.

Then, the ballast water is introduced into the grinder part 100, and the aquatic organisms in the ballast water are pulverized by the rotation of the grinder 110, thereby sterilizing the ballast water.

The operation of the grinder unit according to another embodiment will be described with reference to FIG. 5. First, the motor unit 120 is driven according to the ballast water inflow detection signal generated in the inlet valve 40, And the rotating shaft 130 rotates in one direction in accordance with the driving of the power transmitting unit 121 to kill the aquatic organisms in the ballast water flowing into the grinder unit 100. [
