And a hub 532 movably coupled to a drive shaft 540 penetrating the central portion of the plate portion 531, wherein the hub 532 is an inner core portion that is screwedly coupled to an outer circumferential surface of the drive shaft 540. 5322 is characterized in that the coupling to the hub body (5321) without using a screw fit.

First, the general structure and functions of the body 10, the ultraviolet lamp unit 30, and the cleaning unit 50 used in the ultraviolet processing apparatus according to the present invention will be described.

The body 10 constitutes the body of the ultraviolet treatment apparatus according to the present invention and the ballast water flowing through the inflow portion 124 and the outflow portion 125 formed on the side thereof passes through the inside of the body 10 Which is irradiated with ultraviolet rays, and then flows out.

The ultraviolet lamp unit 30 includes an ultraviolet lamp 310, a sleeve tube 320, an ultraviolet sensor 340, and the like, for irradiating ultraviolet rays to the ballast water passing through the inside of the body 10, do. The ultraviolet lamp 310 is configured to emit ultraviolet rays to emit ultraviolet rays. The ultraviolet lamp 310 is formed in a rod or rod shape and has electrodes 311 at both ends thereof. The electrodes 311 are vertically arranged in the flow direction of the ballast water, Both ends of the ultraviolet lamp 310 are inserted into the side partition walls 130 inside the body 10, which separates the ballast water into a flowing space and a non-flowing space. The sleeve tube 320 surrounds the ultraviolet lamp 310 to protect the ultraviolet lamp 310. When foreign matter adheres to the surface of the sleeve tube 320, the intensity of the ultraviolet light emitted from the ultraviolet lamp 310 The surface of the sleeve tube 320 is removed by the cleaning unit 50, which will be described later. The ultraviolet ray sensor 340 measures the ultraviolet ray intensity within the body 10 and measures the intensity of the ultraviolet ray in the body 10 so that the ultraviolet ray intensity can be maintained within a certain range effective for ultraviolet ray treatment. Not shown) to be utilized in the operation of the ultraviolet processing apparatus.

The wiper 510 removes foreign substances and is connected to an ultraviolet lamp 310 An arm 530 for connecting the wiper body 520 to the drive shaft 540 and a drive shaft 530 for driving the arm 530 to move the arm 530. [ And a drive motor 550 that provides power to the motor 540.

As pointed out as a problem of the prior art, in the case of the conventional UV treatment apparatus, as shown in Figs. 1, 18 and 2, the arm 10043 to which the plurality of wiper bodies 10042 are radially attached is a hub. It is coupled to the drive shaft 10041 for moving the arm 10043 in the front and rear direction through the 100431. However, as shown in FIG. 2, in the conventional coupling structure of the hub 100431 and the drive shaft 10041, the inner diameter of the hub 100431 is coupled to a separate inner core 100432 to the inner diameter of the inner core 100432. The formed screw bone is screwed with the screw thread of the outer peripheral surface of the drive shaft (10041) in conjunction with the rotation of the drive shaft (10041) to move the arm (10043) in the front and rear direction, at this time, the inner core coupled to the hub (100431) and its inner diameter ( 100432) is used between the coupling method using a screw. However, when the hub 100431 and the inner core 100432 are coupled with each other using the screw, one end of the screw is positioned at the inner core 100432, so that the rotation of the drive shaft 10041 and the rotation of the arm 10043 One end of the screw inserted in the inner core 100432 to receive a moment during the movement process is continuously subjected to the rotational force so that the screw is loosened so that the drive shaft 10041 rotates, A problem of not moving, and a problem of deviation of the inwardness 100432 occur.

Accordingly, in the present invention, as shown in FIGS. 3, 4, 5, 6, and 7, in the structure of the hub 532, an inner core portion 5320 which is screwed to the outer circumferential surface of the drive shaft 540. ) Is coupled to the inner diameter of the hub body (5321) without the use of screws to fit tightly to be able to fundamentally prevent the separation between the hub body (5321) and the inner core portion 5322 in use.

To this end, in the present invention, as shown in FIGS. 6 and 7, the inner core accommodating groove 5311 1 is formed in the hub body 5321 to accommodate the inner core 5322. After inserting the inner core part 5322, the hub body 5321 and the inner core part were closed by engaging a separate cover part 5323 to close the open part of the inner core receiving groove 5311 1 into which the inner core part 5322 was inserted. The inner core portion 5322 is firmly coupled to each other so that the inner core portion 5322 is not separated without the direct screwing between the joints 5322. The diameter of the inner core receiving groove 53211 is preferably equal to or slightly smaller than the outer diameter of the inner core 5322 so that the inner core 5322 is press-fitted into the inner core receiving groove 53211.

More specifically, at one end portion of the inner core portion 5322, which is in contact with the lid portion 5323, a chamfered portion 53221 chamfered to have a reduced outer diameter is formed, and the lid portion 5323, The insertion hole 53231 is formed at the central portion of the insertion hole 53231 so that one end of the insertion portion 53221 of the inner shaft portion 5322 can be inserted into the insertion hole 53231, And is formed in a shape corresponding to one end of the formed inner core portion 5322 so that one end of the inner core portion 5322 formed with the chamfered portion 53221 in the insertion hole 53231 can be accurately fitted and inserted. In this way, when one end of the inner core portion 5322 having the chamfered portion 53221 formed in the insertion hole 53231 of the lid portion 5323 is correctly inserted and joined to the outer periphery of the generally cylindrical inner core portion 5322, It is possible to fundamentally prevent the inner core portion 5322 from rotating in the inner core receiving groove 53211 due to the chamfered portion 53221 chamfered (preferably planarly chamfered) so that the outer diameter is reduced.

The hub body 5321 includes an inner core receiving portion 53212 protruding toward the center of the inner core receiving groove 53211 at the other opposite end of the one side where the lid portion 5323 is engaged, The other end portion of the inner shaft portion 5322 inserted into the deep portion receiving groove 53211 (i.e., the opposite end portion of the one end portion formed with the chamfered portion 53221) is caught by the inner deep portion receiving portion 53212, So that it is prevented from departing from the groove 53211.

The hub body 5321 and the lid 5323 are formed of stainless steel to prevent corrosion and the inner core 5322 is formed of PEEK (Polyetheretherketone) or Teflon.

3, 4, 8 and 9, the ultraviolet light processing apparatus according to another embodiment of the present invention a plurality of ultraviolet sensors 340 for measuring the intensity of the ultraviolet light emitted from the ultraviolet lamp 310. In addition, even when any one of the plurality of ultraviolet sensor 340 does not operate, a control unit (not shown) for controlling the overall operation of the ultraviolet processing device utilizes another ultraviolet sensor 340 to operate the ultraviolet processing device. It can be operated continuously without interruption.

In the case of a conventional ultraviolet light treatment apparatus, as shown in FIGS. 1 and 10, an ultraviolet sensor 1007 for measuring the intensity of ultraviolet light irradiated by an ultraviolet lamp 1002 in the body 1001 includes a body 1001. Since there exists a singular in the inside, the control unit (not shown) for controlling the overall operation of the ultraviolet light treatment device receives the measurement value only from the ultraviolet sensor 1007 that exists alone to control the operation of the ultraviolet light bar. If the sensor 1007 fails, the operation of the ultraviolet processing apparatus needs to be stopped during the operation of repairing and replacing the ultraviolet sensor 1007, thereby causing an inefficient operation in operation. The ultraviolet ray sensor 1007 positioned at a specific point of the body 1001 is most affected by ultraviolet ray intensity emitted from the ultraviolet ray lamp 1002 in the vicinity of the ultraviolet ray sensor 1007 The ultraviolet lamp 1002 in the vicinity of the ultraviolet ray sensor 1007 irradiates the ultraviolet ray with normal intensity and the ultraviolet ray lamp 1002 far from the ultraviolet ray sensor 1007 emits ultraviolet The ultraviolet ray intensity measured by the ultraviolet ray sensor 1007 is measured and transmitted within a normal value so that the ballast water far away from the ultraviolet ray sensor 1007 can not be prevented from being untreated and flowing out.

Therefore, in the present invention, as shown in Figure 3, 4 and 8, in the body 10 to include a plurality of ultraviolet sensor 340 for measuring the intensity of the ultraviolet light emitted from the ultraviolet lamp 310 Even when any one of the plurality of ultraviolet sensors 340 does not operate, a controller (not shown) for controlling the overall operation of the ultraviolet processing device does not stop the operation of the ultraviolet processing device by using another ultraviolet sensor 340. Keep it running. That is, as shown in FIG. 8, in the case of the ultraviolet sensor 340 installed in the body 10 at a predetermined interval, even if one specific ultraviolet sensor 340 becomes inoperative, the entire ultraviolet processing apparatus is replaced for the replacement. The controller (not shown) can continuously control the overall operation of the ultraviolet light treatment device based on the ultraviolet light intensity measurement values measured by the remaining ultraviolet light sensors 340 without stopping the operation.

Further, in the control unit (not shown), the average value of the measured values measured by the plurality of installed ultraviolet sensors 340 may be calculated and the operation of the ultraviolet ray processing apparatus may be more accurately controlled using the average value. That is, when the ultraviolet ray sensor is installed in only one specific site as described above, ultraviolet lamps in the vicinity of the ultraviolet ray sensor are irradiated with ultraviolet rays of normal intensity, The intensity of ultraviolet light measured by the ultraviolet sensor is measured and transmitted within a normal value to cause a problem of accurate control and lowering of processing efficiency even when ultraviolet rays below the normal value are irradiated. The ultraviolet light intensity of the region where the intensity of the ultraviolet light is relatively large is compared with the intensity of the ultraviolet light of the region where the intensity of the ultraviolet light is relatively small, 10) Calculate the average intensity of ultraviolet rays in the whole Since the use of the control, if the average intensity of the ultraviolet light emitted in the entire inner body 10 is less than the reference value is possible (control unit) can be prevented from being the number of untreated ballast outlet to stop the operation.

In addition, in the present invention, when the ultraviolet sensor 340 is installed and operated in the presence of at least three ultraviolet sensors 340, the control unit (not shown) determines that the measured value among the ultraviolet sensors 340 is significantly The difference between the ultraviolet sensor 340 and the ultraviolet sensor 340 is determined by comparing the measured value of the ultraviolet sensor 340 classified as an error with the ultraviolet sensor 340 that is an operation (function) error with respect to the ultraviolet sensor 340, So that the operation of the processing apparatus can be controlled. That is, in general, even when the function of the ultraviolet lamp 310 is deteriorated and the intensity of the ultraviolet light to be irradiated is weakened, the degree is gradually weakened over a certain period of time. In general, the intensity is suddenly suddenly weakened. On the contrary, when the measurement value of ultraviolet ray intensity measured by a specific ultraviolet ray sensor 340 suddenly drops suddenly, most of the time is mostly due to a problem of the ultraviolet ray sensor 340 itself. Particularly when considering that the ultraviolet ray sensor 340 measures the intensity of ultraviolet rays irradiated from a plurality of ultraviolet lamps 310 provided around the ultraviolet ray sensor 340, That is more so. Accordingly, the controller may operate (function) the ultraviolet sensor 340 whose measured value is significantly different from the calculated average value among the three or more ultraviolet sensors 340 installed in the body 10, The measurement value of the ultraviolet ray sensor 340 classified as an error classified into the error ultraviolet ray sensor 340 is excluded from the average value calculation so that the error is excluded compared with the average value including the error, It is possible to more accurately control the operation of the ultraviolet ray treatment apparatus by using an average value obtained by calculating an accurate average.

In addition, referring to FIG. 9, in the present invention, the partition wall 130 flows into a space in which the ballast water flowing through the inlet 124 and outflowing through the outlet 125 flows and does not flow. Separated by the UV lamp 310 is arranged perpendicular to the flow direction of the ballast water passing through the inlet portion 124 and the outlet portion 125 so that both ends are coupled by the partition wall 130, respectively. In the structure, the electrodes 311 (not irradiated with ultraviolet rays in the vicinity of the electrode 311), which are positioned at both ends of the ultraviolet lamp 310, protrude a predetermined length from the partition wall 130 toward the space through which the ballast water flows. As the portion directly irradiated with ultraviolet rays from the length of the ultraviolet lamp 310 in the space in which the ballast water flows is considered, the gap D4 between the electrodes 311 and the electrodes 311 on both sides, the inflow The diameter D5 of the part 124 or the outflow part 125 is formed to be equal to or smaller than the distance D4 between the both side electrodes of the ultraviolet lamp 310. [ That is, the ballast water flowing into the body 10 through the inlet 124 is not between the electrodes of the ultraviolet lamp 310 directly irradiated with ultraviolet rays at the beginning of the inflow, The diameter D5 of the inflow part 124 is set to be larger than the diameter D5 of the inflow part 124 of the ultraviolet lamp 310 so as to prevent the ultraviolet rays from being directly irradiated while moving along the partition wall 130, The ballast water can flow in the direction between the two electrodes of the ultraviolet lamp 310 directly irradiated with the ultraviolet rays directly at the initial stage when the ballast water is introduced through the inflow portion 124, And the treatment effect is enhanced.

3, 4, and 11 to 13, in the ultraviolet processing apparatus according to another embodiment of the present invention, the body 10 has a cross section 110 perpendicular to the direction in which the ultraviolet lamp 310 is inserted, And the ultraviolet lamps 310 are uniformly arranged at regular intervals in the rectangular cross section 110 to minimize the number of ultraviolet lamps arranged in a cross sectional area.

In the conventional cylindrical UV treatment apparatus having a circular cross section, since the ultraviolet lamps 1002 should be arranged closely at regular intervals in the body 1001 of the circular cross section, the number of ultraviolet lamps compared to the cross-sectional area is increased and power consumption is increased. Even in the case of increasing the number of ultraviolet lamps to increase the ballast water treatment capacity, as one columnar column is arranged, the cross-sectional area of the body 1001 increases by the square of the increasing radius (circular cross-sectional area: πr ² ). Also, it is not possible to increase the capacity of the ballast water in small units because the newly added heat must be arranged with a larger number of ultraviolet lamps than the previous heat (because the circumference of the newly added heat becomes larger than the circumference of the previous heat). As a result, there was a problem of being limited in an appropriate increase in processing capacity as needed (see FIG. 10), FIG. 3. As illustrated in FIG. 11, when the body 10 has a hexahedral shape as a whole, the cross section 110 perpendicular to the direction in which the UV lamp 310 is inserted forms a quadrangular shape, the UV lamp ( 310 is a line 330 (hereinafter referred to as 330-n (n = 1 to 5)) arranged in a line perpendicular to the flow direction of the ballast water in the rectangular cross section 110 of the body 10. The line 330 is sequentially numbered from the inlet 124) may be arranged to form a plurality of lines 330 in a form spaced apart at regular intervals along the flow direction of the ballast water, bar need In order to increase the number of UV lamps in small scale, the cross-sectional area of the body 10 may be increased only by the portion where one line 330 is sequentially added as shown in FIG. Cross section Is a surge in the proper processing capacity increased as necessary without inefficient problem that must be arranged further back to the first ultraviolet lamp 310 was not needed for padding the portion can be realized. In addition, the rectangular cross section 110 according to the present invention in which the ultraviolet lamps 310 are arranged in a row has a number of ultraviolet lamps arranged in the same cross-sectional area (with the same interval) compared with the circular cross section in which the conventional ultraviolet lamps are arranged in the column- The power consumption of the same capacity can be reduced. In addition, in forming a large-capacity ultraviolet ray treatment apparatus, it becomes advantageous (occupies a smaller volume).

11 and 12, in the present invention, in order to arrange the ultraviolet lamp 310 in a plurality of lines 330 in the rectangular cross section 110, When the ultraviolet lamp 310 of the second line 330-2 spaced apart from the first line 330-1 by a predetermined distance in the flow direction of the ballast water flows in the first line 330-1 , The flow of the ballast water strikes the ultraviolet lamp 310 as shown in FIG. 12, thereby preventing the flow of the ballast water from flowing out while maintaining the flow of the straight line. I can do it. That is, as pointed out as a problem of the prior art (see FIG. 10), when the ultraviolet lamp 1002 is arranged in a columnar shape, the number of ballasts passing through the inside of the ultraviolet treatment device does not directly contact the ultraviolet lamp 1002. When a straight line passes between the UV lamps 1002 (see ⓐ, ⓑ, ©), the effect of UV treatment is not only ultraviolet light intensity but also proportional to the time of irradiation with ultraviolet light. The flow of the ballast water (see ⓐ, ⓑ, ⓒ) passing in a straight line without hitting the lamp 1002 has a problem that the UV treatment effect is reduced as the flow rate is relatively fast and the time to irradiate ultraviolet rays is also reduced. In the present invention, the flow of the ballast water must hit the ultraviolet lamp 310 as described above, the speed is changed while the flow is slowed By making the amount of time investigating the line it can be increased, leading to an increase the UV treatment effect.

In addition, in the present invention, between the line 330 and the line 330 is a drive shaft 540 for moving the arm 530 coupled to the wiper 510 to remove the foreign matter attached to the UV lamp unit 30 If the drive shaft 540 is located on the center line 330 of the three lines 330 to cause interference between the ultraviolet ray lamp 310 and the driving shaft 540. 11, the interfering ultraviolet lamp 310 is arranged in front and / or rear of the ballast water in the flow direction of the ball shaft 540 so that the flow of the ballast water does not collide with the ultraviolet lamp 310. Will be prevented.

3, 4, 16 and 17, the ultraviolet processing apparatus according to another embodiment of the present invention separates the space in which the ballast water flows and the space in which the ballast water flows, The partition 130 is integrally formed on the body 10 so that the partition 130 can be installed and replaced without complicated assembling operation of coupling the partition 130 to the body 10 .

As shown in FIGS. 14 and 15, the conventional ultraviolet processing apparatus includes a partition wall (not shown) for partitioning a space through which ballast water flows and a space through which ballast water flows, 1003 are coupled to both sides of the body 1001 in a assembled manner using bolts. However, in the conventional structure in which the partition 1003 is assembled by bolts on both sides of the body 1001, the assembling work of the partition 1003 and the body 1001 using bolts is cumbersome and takes a long time, It is difficult to precisely match the center of the partition 1003 with the body 1001. When the center of the partition 1003 and the body 1001 can not be precisely aligned with each other, The center of the lamp insertion hole 10031 (for insertion of the ultraviolet lamp 1002) formed in the partition wall 1003 which is coupled to both sides of the lamp compartment 1003 is also connected to the lamp insertion hole 10031 of one side partition wall and the lamp insertion hole 10031 of the other side partition wall. (See Fig. 15), the ultraviolet lamp 1002 having both ends inserted into the lamp insertion holes 10031 of both sides eccentric to each other can be easily operated during operation Breakable Thereby causing the problem.

Accordingly, in the present invention, as shown in FIGS. 3, 4, 16, and 17, the four sides (four sides) surrounding the four corners forming the rectangular section 110 perpendicular to the direction in which the ultraviolet lamp 310 is inserted (The side surface 123 on which the upper surface 121, the lower surface 122, the inflow portion 124 and the outflow portion 125 are located) and the hexahedron shaped body 10 formed by the four surfaces, So that the partition 130, which is located at a certain depth in the opened both sides of the body 10, is formed integrally with the body 10.

When the barrier ribs 130 are integrally formed in the body 10, it is possible to reduce the troublesome process and time required for separately assembling the barrier ribs to the body, 17, a lamp insertion hole 131 is formed in the lamp insertion hole 131 so that one end of the ultraviolet lamp 310 is inserted into the lamp insertion hole 131, Since the centers of the lamp insertion holes of the partition 130 located at the other side of the body 10 are made to coincide with each other (i.e., the shape formed and maintained in the factory without eccentricity due to errors in the assembly process) , The ultraviolet lamp 310 having both ends inserted between the lamp inserting hole 131 and the lamp inserting hole 131 arranged on the same axis ensures durability that is not easily broken even in the continuous operation .

In the present invention, the installation and replacement of the components of the cleaning unit 50, which are located between the partition 130 and the partition 130 as the partition 130 is integrally formed in the body 10, A hole 1211 may be formed on the upper surface 121 or the lower surface 122 of the body 10 and include an upper lid 1212 for opening and closing the hole.

That is, when the partition 130 is integrally formed in the body 10, the components of the cleaning unit 50 (the wiper body 520) positioned between the partition 130 and the partition 130, The arm 530 having the largest volume on the upper surface 121 or the lower surface 122 of the body 10 may be separately mounted on the upper surface 121 or the lower surface 122 of the body 10, The installation and replacement work of various components in the body 10 can be easily performed regardless of the integrated structure of the partition 130 by forming the installation and repair holes 1211 with a size enough to be inserted. Since the installation and maintenance hole 1211 must be sealed when there is no operation, the upper cover 1212 is used to seal off the ballast water when not in use.

3, 4, 19, and 20, the ultraviolet processing apparatus according to another embodiment of the present invention includes a cleaning unit 50 that removes a foreign substance by integrating a range of ultraviolet lamps 310 Even if the number of the ultraviolet lamps 310 to be installed increases due to an increase in the capacity of the ultraviolet processing apparatus, the cleaning unit 50 'can be arranged in parallel to effectively remove foreign matter .

1 and 18, since the body 1001 of the ultraviolet processing apparatus is formed in a cylindrical shape, the ultraviolet lamp 1002 disposed inside the body 1001 is also formed in the cylindrical shape of the body 1001, The configurations of the cleaning portion 1004 for removing foreign substances on the surface of the UV lamp 1002 arranged in a columnar shape are also arranged on an axial line that coincides with the central axis of the body 1001 A wiper body 10042 surrounding the ultraviolet lamp 1002 arranged in a columnar shape around a driving shaft 10041 disposed in the housing 10041 is radially arranged and an arm 10043 for connecting the wiper body 10042 to the driving shaft 10041 Even when the number of the ultraviolet lamps 1002 is increased and the ultraviolet lamps 1002 are arranged in a plurality of columns in a columnar manner, even when one cleaning unit 10041 is disposed around one driving shaft 10041, (this A drive shaft, thereby causing the wiper body, various problems cancer is also one of the means yirum the unit as a set) only can not be applied because the resulting non furnace and heavy due to the drive shaft (10041) and the arm (10043).

Accordingly, in the present invention, as shown in FIGS. 3, 4, 19, and 20, the cleaning unit 50 ', which is a set of the driving shaft 540, the wiper body 520, and the arm 530, (Cross-section) of the body 10 and increase the number of ultraviolet lamps 310 inserted into the body 10, that is, the number of lines 330, , The cleaning unit 50 'is further arranged in parallel so that the cleaning unit 50' itself can effectively remove foreign matter while preventing the cleaning unit 50 'from becoming large and heavy.

The washing unit 50 'set in this specific size (if necessary, the washing unit 50' of the size covering the two lines of the line 330 of the ultraviolet lamp 310 and the washing unit 50 ' 20, the cross section of the body 10 is elongated in a specific direction so that the arrangement of the ultraviolet lamps 310, that is, the line 330, The cleaning unit 50 'can be covered only by arranging the cleaning units 50' in parallel in accordance with the increase in the number of the cleaning units 50 ' And the arm 530 of the cleaning unit 50 'is formed to be excessively long from the drive shaft 540 to restrict the smooth movement of the arm 530 during the operation, Or the diameter of the drive shaft 540 is excessively large It increases it is possible to prevent various problems caused by heavy furnace.

The driving shaft 540 for moving the arm 530 coupled with the wiper 510 for removing the foreign substances adhering to the ultraviolet lamp unit 30 is disposed between the line 330 and the line 330 If the drive shaft 540 is positioned on the center line 330 of the three lines 330 and interference occurs between the drive shaft 540 and the ultraviolet lamp 310, , The interfered ultraviolet lamp 310 may be arranged in front of and / or behind the ballast water in the flow direction of the ballast water with respect to the drive shaft 540 as shown in FIG. 19 so that the flow of the ballast water does not collide with the ultraviolet lamp 310 .

3, 4, 5 to 25, the ultraviolet light treatment apparatus according to another embodiment of the present invention is the ultraviolet lamp 30 in the cleaning unit 50 (more specifically, the ultraviolet lamp ( The wiper 510 for removing the foreign matter adhered to the surface while contacting the sleeve tube 320 for protecting the 310 is the main wiper 511 and the auxiliary wiper 512 on the inner circumferential surface of the wiper body 520, respectively. It is formed in the shape of the insertion coupled to be characterized in that to remove the foreign matter attached to the ultraviolet lamp unit 30 in duplicate. The wiper body 520 is a frame that annularly surrounds the ultraviolet lamp unit 30 (more specifically, the sleeve tube 320 that protects the ultraviolet lamp 310) And a wiper 510 is inserted and coupled to the inner circumferential surface of the wiper body 520 to remove the wiper 510 in contact with the foreign matter.

1, 18, 21, and 22, a single wiper 10044 is inserted into and coupled to the inner circumferential surface of the annularly formed wiper body 10042 to form the wiper body 10042, The foreign substances adhering to the surface of the ultraviolet lamp 1002 are removed. However, when only a single wiper 10044 is inserted into and engaged with the wiper body 10042, a single wiper 10044 interlocks with the wiper body 10042 in the forward and backward bi- The wiper 10044 itself is easily deformed or worn because the wiper 10044 continues to be frictionally bent while being bent backward at the time of the rearward movement. Therefore, there is a demand for replacing the wiper 10044 at a faster cycle, Frequently occurs. In addition, when the wiper 10044 moves in a backward and forward bi-directional movement of the wiper body 10042 and moves backward while moving backward, when the wiper 10044 moves backward, the foreign matter attached to the surface of the ultraviolet lamp 1002 is removed The distal end portion of the wiper 10044 is excessively ductile (that is, the distal end portion of the wiper 10044 is excessively retracted), so that the force for removing the foreign matter is lowered, thereby deteriorating the efficiency of foreign matter removal.

Therefore, in the present invention, as shown in Figures 3, 4, 5 to 25, the main wiper 511 and the auxiliary wiper 512 is inserted into the inner peripheral surface of the wiper body 520, respectively. The foreign material attached to the ultraviolet ray lamp unit 30 (more specifically, the sleeve tube 320 to protect the ultraviolet ray lamp 310) is to be removed twice.

The main wiper 511 is disposed at the center of the inner circumferential surface of the wiper body 520 and removes foreign substances adhered to the UV lamp 30 inserted in the inner circumferential surface of the wiper body 520. The main wiper 511 is made of EPDM (Ethylene Prophylene Diene Monomer ) Rubber, MBR rubber, fluorine rubber, and the like. Unlike the conventional single wipers, the main wipers 511 are disposed on both sides of the main wipers 511, and the auxiliary wipers 512, which will be described later, It is possible to more effectively remove the foreign substances adhering to the surface of the ultraviolet lamp unit 30 (more specifically, the sleeve tube 320 protecting the ultraviolet lamp 310).

The main wiper 511 has a first blade 5111 and a second blade 512. The first blade 5111 and the second blade 5111 are disposed on the left and right sides of the groove 5112 forming a space with a portion of the main wiper 511 contacting the surface of the ultraviolet lamp unit 30, The first blade 5111 or the second blade 5113 may be inserted into the groove 5112 when the arm 530 and the wiper body 520 connected thereto are moved forward or backward including the second blade 5113, It is possible to move smoothly simultaneously with removal of foreign substances while being pushed into the space. That is, if the distal end of the main wiper 511 is kept at a right angle to the surface of the sleeve 320 without being bent at any one of the ends during the movement of the distal end of the main wiper 511, In addition, if the distal end of the main wiper 511 is pushed (biased) in both directions due to back and forth reciprocating movement, the distal end is excessively retracted, When the first blade 5111 and the second blade 5113 are configured to be centered around the recessed groove 5112 therebetween as described above, The first blade 5111 is pushed into the space of the groove 5112 to remove the foreign material. On the other hand, when the wiper body 520 moves in the other direction The second blade 5113 is pushed into the space of the groove 5112 to remove the foreign substance. Therefore, when the first blade 5111 and the second blade 5113 are both moved in a specific direction So that the deformation and the wear are relatively reduced as compared with the case where both directions are bent in all directions in the forward and backward directions. If the foreign matter can not be removed from the first blade 5111 or the second blade 5113 which first comes into contact with the foreign matter, the other blade 5113 or the first blade 5111 may again remove the foreign matter So that the efficiency of removing foreign matters can be increased.

The auxiliary wipers 512 are positioned on both sides of the main wiper 511 so that the arm 530 and the wiper body 520 connected to the arm 530 move forward or backward when the UV lamp unit 30 (more specifically, (The sleeve tube 320 for protecting the ultraviolet lamp 310) can be caught and removed by the auxiliary wiper 512 primarily before the main wiper 511 is wiped, and the material such as Teflon As shown in FIG. The auxiliary wipers 512 and the main wipers 511 are used to remove foreign matter from the main wiper 511 due to the presence of the auxiliary wiper 512 located on both sides of the main wiper 511, The foreign matter adhering to the surface of the ultraviolet lamp unit 30 (more specifically, the sleeve tube 320 protecting the ultraviolet lamp 310) can be more effectively removed.

The auxiliary wiper 512 includes an inclined protrusion 5121 protruding obliquely by '? 1' in a direction toward the outside of the inner peripheral surface in the body of the auxiliary wiper 512 and is inclined from the inner peripheral surface of the auxiliary wiper 512 toward the outer front direction The protruding protrusions 5121 are formed so as to be in line contact with the surface of the sleeve tube 320 so as not to be in surface contact with the surface of the sleeve tube 320. The surfaces of the sleeve tube 320 and the auxiliary wiper 512 can be effectively removed while minimizing the friction between them. That is, as shown in FIG. 25, since the auxiliary wiper 512 forms an inclined protrusion part 5121 protruding inclined outwardly from the inner circumferential surface thereof, the entire inner circumferential surface of the auxiliary wiper 512 is sleeve tube 320. The end of the inclined protrusion (5121) is not in contact with the surface, but only the end of the inclined protrusion (5121) in contact with the surface of the sleeve tube 320 to remove foreign matter adhered to the surface, in particular, the end of the inclined protrusion (5121), that is, the sleeve tube Since the sharp portion 5222 is formed so that the portion in contact with the surface of the 320 may be in line contact instead of surface contact, the foreign material is removed while minimizing friction with the surface of the sleeve tube 320. Since the inclined projection 5121 is inclined in the forward direction with respect to the advancing direction of the wiper body 520, the inclined projection 5121 is not vertically abutted against the surface of the sleeve tube 320, The foreign matter on the surface of the sleeve tube 320 can be removed more effectively.

3, 4, 5, 27 to 29, in the ultraviolet treatment apparatus according to another embodiment of the present invention, the arm 530 is excessively out of a predetermined range in the cleaning unit 50 excessively It includes a reed switch 560 for preventing the forward or backward movement, the reed switch 560 is inserted into the magnet 563 inside and can be assembled in a prefabricated manner to prevent degeneration of the magnet 563 by welding Characterized in that. The reed switch 560 attached to the arm 530 detects the magnetic force of the magnet 563 contained in the reed switch 560 by the magnetic force sensor attached to the partition wall 130 in the body 10, The signal is transmitted to a control unit (not shown) to control the movement direction of the arm 530 to be switched.

In the case of the conventional UV treatment apparatus, as shown in Figures 1, 18 and 26, the reed switch 10045 for detecting that the arm 10043 in the cleaning unit 1004 does not excessively move forward or backward beyond a certain range. ) Is a structure in which the entire outside is sealed by welding while the magnet 100451 is included therein. However, when the entirety of the outside is sealed by welding in a state where the magnet 100451 is contained in the inside of the reed switch 10045 as in the conventional reed switch 10045, The magnetic force is weakened or lost and the function as the reed switch 10045 is deteriorated. Further, the entire outer surface of the reed switch 10045 is formed of a metal material (for example, stainless steel) for the welding operation. The surface of the reed switch 10045, which is always located in the ballast water, Powder or the like attached to the reed switch 10045 causes corrosion of the dissimilar metals between the stainless metal material on the outer surface of the reed switch 10045 and the iron powder attached to the surface of the reed switch 10045, So that a problem of rapid progress occurs.

Therefore, in the present invention, as shown in Figures 3, 4, 5, 27 to 29, the reed switch 560 is to be assembled / sealed prefabricated in the state that the magnet 563 is inserted therein. It is possible to prevent the deformation of the magnet 563 by welding. That is, as shown in FIGS. 27 to 29, the reed switch 560 includes an accommodating groove 561 into which an elastic member 562 and a magnet 563 may be inserted at both ends, and the accommodating groove 561. After the elastic member 562 and the magnet 563 is inserted into the receiving groove 561 may include a cover member 564 for sealing the receiving groove 561.

The receiving groove 561 has a first inner circumferential surface 5611 formed with a threaded hole 5613 and a second inner circumferential surface 5611 having a larger diameter than the first inner circumferential surface 5611, The cover member 564 includes a thread 5643 that engages with the threaded portion 5613 of the first inner circumferential surface 5611. The second inner circumferential surface 5612 has a protruding jaw 5614 formed thereon, And a second outer circumferential surface 5642 having a larger outer diameter than the first outer circumferential surface 5641 and having a jaw coupling groove 5644 in which the jaws 5614 are received and engaged, have. Therefore, when the cover member 564 is inserted into the receiving groove 561, as shown in FIG. 28, the first outer circumferential surface 5561 of the cover member 564 has a screw thread 5603. The first inner circumferential surface (5611) of the 561 is screwed to the screw bone 5613, and when the coupling between both is completed, as shown in Figure 29, the second outer peripheral surface 5564 jaw of the cover member 564 The second inner circumferential surface 5612, the jaw 5614 of the accommodation groove 561 is accommodated in the coupling groove 5444 so that the accommodation groove 561 and the cover member are resilient by the elastic member 562 in the accommodation groove 561. 564 prevents loosening of screws and maintains airtightness.

At this time, a tapered portion 5615, which is sloped and chamfered, is formed on a surface of the protruded surface of the jaw 5614 facing the opened portion of the receiving groove 561, The tapered portion 5645 which is sloped and chamfered is also formed in the stepped portion forming the boundary between the first outer peripheral surface 5641 and the second outer peripheral surface 5642 so that the cover member 564 can be easily inserted into the receiving groove 561. [ The first outer circumferential surface 5641 of the cover member 564 and the second outer circumferential surface 5641 of the cover member 564 are engaged with the jaw 5614 protruding from the inner circumferential surface of the receiving groove 561 in the process of inserting the cover member 564 into the receiving groove 561, In order to prevent the jaw 5614 and the like from being damaged by injecting an unreasonable force as the stepped portion forming the boundary of the outer peripheral surface 5642 is interfered with the insertion of the cover member 564, A surface facing the opened portion of the receiving groove 561 among protruded surfaces of the jaw 5614 which is a portion (interfering) that is encountered (interfered) when the cover member 564 is inserted to facilitate the insertion of the cover 564 Tapered portions 5615 and 5645 which are slantingly chamfered are formed on the stepped portions forming the boundary between the first outer peripheral surface 5641 and the second outer peripheral surface 5642 of the cover member 564.

The cover member 564 includes a stopper 5646 that protrudes outward from the second outer circumferential surface 5642 and is in close contact with the distal end of the receiving groove 561 so that the cover member 564 is inserted into the receiving groove 561, So that it can be accurately sealed. If the cover member 564 does not have the same configuration as the stopper 5646, when the cover member 564 is inserted into the receiving groove 561 at an excessive depth or is inserted in a state of being inserted less The cover member 564 may protrude outward from the second outer circumferential surface 5642 of the cover member 564 to prevent the airtightness between the cover member 564 and the receiving groove 561 from being maintained. A stopper 5646 that is in close contact with the distal end of the receiving groove 561 is formed so that the depth of insertion of the cover member 564 into the receiving groove 561 can be precisely adjusted.

The cover member 564 may be formed of a nonmetallic material (e.g., PEEK (Polyetheretherketone) or the like) and may be formed of a metal component such as iron powder contained in the ballast water and attached to the surface of the cover member 564 The second outer circumferential surface 5642 of the cover member 564 or the second inner circumferential surface 5612 of the accommodating groove 561 is provided with a hermetic seal A separate groove in which the O-ring 565 for the O-ring 565 is to be formed.

3, 4, 31 to 33, the ultraviolet treatment apparatus according to another embodiment of the present invention is the drive shaft 540 for moving the arm 530 of the cleaning unit 50 is the body (10) is inserted into and supported in the drive shaft insertion hole 132 of the partition 130 for partitioning the space in which the ballast water flows and the non-flowing space, and the drive shaft 540 is inserted into the drive shaft insertion hole 132. Contact surface between the rotor 541 rotating together with the drive shaft 540 in the coupling structure of the part and the stator 542 coupled to the cover frame 544 fixed to the partition wall 130 around the drive shaft insertion hole 132 ( 5411) the ballast water is prevented from being leaked (that is, into the space where the ballast water in which the electronic equipment, etc. are located) does not flow.

In the case of the conventional ultraviolet treatment device, as shown in Figure 1, 14 and 30, the drive shaft 10041 for moving the arm 10043 of the cleaning unit for removing the foreign matter attached to the ultraviolet lamp 1002 in the body 1001 ) Is connected to the drive motor so that one end of the drive shaft 10041 may drive the drive shaft insertion hole 10032 of the partition 1003 partitioning the space in which the ballast water flows in the body 1001 and the space in which the ballast water does not flow. Since it penetrates and is connected to the drive motor, it is important to maintain airtightness at the coupling portion between the drive shaft 10041 and the drive shaft insertion hole 10032. Therefore, conventionally, as shown in FIG. 30, the cover member 1005 is closed by using a separate cover member 1005 around the drive shaft insertion hole 10032 into which one end of the drive shaft 10041 is inserted. By installing a member such as a separate O-ring (10051) for maintaining airtightness at the inner circumferential surface of the drive shaft insertion hole (10032) and the outer circumferential surface of each end of the drive shaft (10041) by using a method to prevent the ballast water from flowing out come. However, in such a conventional method, the o-ring 10051 having elasticity is merely press-fitted to maintain airtightness. Therefore, the O-ring 10051, which is in contact with the outer peripheral surface of the drive shaft 10041, (10051), when a certain period of time has elapsed due to abrasion and deformation due to continuous friction, the function is lost, and the problem of periodical replacement after a short period of use occurs.

Therefore, in the present invention, as shown in Figs. 3, 4, 31 to 33, the rotation that rotates together with the drive shaft 540 in order to be able to improve the airtightness, particularly in the portion in contact with the drive shaft 540. Outflow of ballast water (ie, indoors) through close contact between the former 541 and the stator 542 coupled to the cover frame 544 fixed to the partition wall 130 around the drive shaft insertion hole 132. To prevent inflow).

The rotor 541 is coupled to the rotor seating groove 5431 formed at one side of the annular casing 543 which surrounds and drives the drive shaft 540 and rotates together with the annular casing 543 And one surface of the rotor 541 is formed with a contact surface 5411 with one surface of a stator 542 to be described later so that the contact surface 5411 is completely sealed and airtight ) To exert an excellent effect in preventing ballast water leakage. Since the contact surface 5411 formed at the portion where the rotor 541 and the stator 542 to be described later meet is a portion where the rotating rotor 541 and the fixed stator 542 are rubbed, The smoothness of the contact surface 5411 and the formation of the oil film play the most important role in the airtight function, so that it is important that the contact surface 5411 is processed into a perfectly flat state. As described later, since the rotor 541 is pressed by the elasticity of the elastic spring 547 to be described later, wear is not generated between the rotor 541 and the stator 542 on the contact surface 5411 The airtightness is maintained by the formed oil film, and if the abrasion occurs, the rotor 541 is pressed and compensated for by the elasticity of the elastic spring 547, which will be described later, .

The stator 542 is inserted into the drive shaft insertion hole 132 and then inserted into the stator seating groove formed at one side of the cover frame 544 fixed to the partition wall 130 while sealing the drive shaft insertion hole 132 5441, and the contact surface 5411 is formed with one surface of the rotating rotor 541 that is rotated. Particularly, the stator 542 is fixedly coupled with the auxiliary seat 5421 in the stator receiving groove 5441 so that the stator 542 can be inserted at the correct position and depth, So that maintenance can be facilitated.

The annular casing 543 further has a first groove 5432 coupled to one side of a first groove 5432 formed on the outer circumference and a second member 546 coupled to the other side of the first groove 5432, The upper end of the elastic spring 547 supported at the lower end by the first member 545 is moved to the second member 546 by positioning the elastic spring 547 between the member 545 and the second member 546, So that the rotor 541 is pressed against the contact surface 5411 in the direction of the stator 542 so as to be brought into close contact therewith. At this time, the annular casing 543 may be formed of an elastic material such as NBR (acrylonitrile-butadiene rubber), EPDM (Ethylene Prophlene Diene Monomer) or fluorine rubber. That is, as shown in FIGS. 32 and 33, between the first member 545 and the second member 546 coupled to both ends of the first groove 5432 with the elastic spring 547 interposed therebetween. Since it is not fixed to each other, the elastic spring 547 having one end supported by the first member 545 may elastically press and move the second member 546, and thus the rotor 541 may also In the case where abrasion occurs in the contact surface 5411, it is possible to maintain airtightness in the contact surface 5411 because it is pressurized and compensated by the worn amount.

The cover frame 544 is formed with a second groove 5442 at a portion contacting the inner circumferential surface of the drive shaft insertion hole 132 while being coupled to the drive shaft insertion hole 132, A third groove 5443 is formed in a portion contacting the drive shaft 540 and a hermetic member 548 is also formed in the third groove 5443 so that the In addition to the airtight function using the contact surface 5411 between the rotor 541 and the stator 542, airtightness can be maintained by the airtight function using the airtight member 548. That is, as shown in Figure 33, the airtight member 548 inserted into the second groove (5442) is to prevent the ballast water leakage between the inner peripheral surface of the drive shaft insertion hole 132 and the cover frame (544) By performing the airtight function, the airtight member 548 inserted into the third groove (5443) by performing the airtight function to prevent the ballast water leakage between the outer peripheral surface of the drive shaft 540 and the cover frame 544, In the present invention, it is possible to effectively prevent the ballast water outflow from the drive shaft insertion hole 132 through the contact surface (5411) and the airtight member (548). In addition to the screwing for fixing the cover frame 544 to the partition 130 at the upper surface of the cover frame 544, the upper center portion of the cover frame 544 is fixed to the nut 549 5491), the cover frame 544 and the stator 542 are firmly fixed in place so that the airtight function can be effectively performed.

3, 4, 35 to 37, the ultraviolet treatment device according to another embodiment of the present invention is introduced through the inlet 124 in the body 10 is the outlet 125 The first space in which the ballast water does not flow around the space in which the ballast water flows, by the partition walls 130 which respectively support the both ends of the ultraviolet lamp 310 while separating the space in which the ballast water flowing out through the space flows and the non-flowing space. 133 and the second space 134 (the first space 133 and the second space 134 is one side is closed by the coupling of the side cover 126, respectively) are separated on both sides are located And a gas flow line 140 connecting between the first space 133 and the second space 134 which are respectively separated on both sides with respect to the space in which the ballast water flows, and the pressure of the first space 133 on one side. Inlet line (15) to increase (Pure safe air) flowing into the first space 133 through the gas flow line 140 can be simultaneously moved and injected into the second second space 134 through the gas flow line 140. Thus, The pressure inside the space can be uniformly maintained equal to or higher than the external pressure.

In the case of the conventional ultraviolet light treatment apparatus, as shown in Figs. 1, 14 and 34, the internal structure of the body 1001 is partitioned by the partition 1003 partitioning the space in which the ballast water flows and the space in which the ballast water does not flow. In the space where the ballast water does not flow by the partition 1003 (both ends of the ultraviolet lamp 1002 and the driving motor are positioned in this space), the left and right sides of the ballast water flow in the body 1001 respectively. Are separated by. In particular, in an internal space in which an electronic device and the like are installed, the pressure of the internal air is increased to remove harmful air (especially air containing explosive substances) in the ultraviolet ray irradiation apparatus, It is necessary to perform pressure explosion to prevent the inflow of the ultraviolet rays. However, conventionally, the ultraviolet ray blocking device is installed without such pressure explosion. Even if it is assumed that pressure explosion is performed in the conventional UV protection device, both ends of the UV lamp 1002 and the driving motor are installed in the conventional UV treatment device having the internal structure of the body 1001. Since the space where no ballast water does not flow is separated on both sides of the body 1001 and is not connected at all, in order to perform pressure explosion for each space, as shown in FIG. 34, the ballast water separated on both sides does not flow. Since a separate gas inflow line must be installed in each space to inject gas (pure safe air) to increase the internal air pressure, pressure explosion work must be performed separately, and pressure explosion work that is separately performed on both sides of the left and right sides. In the case of equal pressure explosion, There is no choice but to bear difficult problems.

Therefore, in the present invention, as shown in Figs. 3, 4, 35 to 37, the first space 133, respectively separated on both sides with respect to the space in which the ballast water flows inside the body 10 and Through the gas flow line 140 connecting between the second space 134, the first space 133 through the gas inlet line 150 to increase the pressure of one side first space 133 than the external pressure (atmospheric pressure) The gas introduced into the inside (pure safety air) is simultaneously injected into the other second space 134 through the gas flow line 140, so that the pressures in the separated both spaces are equal to or equal to the external pressure. High pressure explosion can be achieved.

35 and 36, the gas flow line 140 may connect both the first space 133 and the second space 134 through the outside of the body 10, wherein the body The gas flow includes an auxiliary flow line 141 which is branched from the gas flow line 140 located outside and connected to a third space 135 covering parts installed outside the body 10. The introduced gas flowing through the line 140 is also injected into the third space 135 through the auxiliary flow line 141, and then, in addition to the first space 133 and the second space 134, the third space 135. At the same time, pressure explosion can be achieved. As described above, due to the characteristics of the ultraviolet processing apparatus installed in a limited space such as a ship, particularly, in an electronic device or the like, the pressure of the inside air is increased in the space separated from the outside, and the harmful air (especially, the air containing the explosive substance) The electronic devices such as the ultraviolet sensor 340, the flow meter, and the temperature sensor installed outside the body 10 have a separate third space 135 for isolating the electronic device from the outside, And the third space 135 is also subjected to a pressure explosion so that the third space 135 is connected to the third space 135 through the structure of the auxiliary flow line 141 that allows the gas flow line 140 to communicate with the third space 135. [ (Pure safe air) flowing through the first space 133 and the second space 134 during the pressure explosion operation can be directly supplied to the auxiliary flow line 141 without performing a separate pressure explosion operation for the first space 133 and the second space 134, Through the third space by injection into 135 so that at the same time be subjected to batch pressure explosion-proof operation, and also, makes it possible to made uniform the pressure-proof for each discrete space.

Referring to FIG. 37, in another embodiment, the gas flow line 140 penetrates between the two partition walls 130 in the body 10 to between the first space 133 and the second space 134. Can be connected. This structure prevents the gas flow line 140 from protruding to the outside of the body 10 to occupy a separate volume, while utilizing the internal space of the body 10, The first space 133 and the second space 134 can be simultaneously subjected to a pressure explosion operation and an equal pressure explosion can be made. However, in this case, the gas flow line 140 in the body 10 is structured so as to cross the space where the ballast water flows between the partition 130 and the partition 130 through the gas flow line 140, The gas flow line 140 which crosses the space through which the ballast water flows is formed of a quartz tube so that the gas flow line 140 passing through the space through which the ballast water flows can not be irradiated with ultraviolet rays So that the ultraviolet ray treatment effect can be maintained without being affected by the ultraviolet ray sterilization effect on the ballast water.

3, 4, 39, and 40, the ultraviolet processing apparatus according to another exemplary embodiment of the present invention includes a body 10 having an interior portion that is introduced into the inflow portion 124, And the ultraviolet lamp 310 is separated from the ultraviolet lamp 310 in the flow direction of the ballast water passing through the inflow portion 124 and the outflow portion 125. The ultraviolet lamp 310 is divided into a space through which the ballast water flows, A protruding blade 160 protruding from the inner side of the body 10 around the outflow portion 125 and having a predetermined length is formed at the inner side of the body 10, (Ultraviolet rays are not irradiated near the electrode 311 of the ultraviolet lamp 310 near the electrodes 311 at both ends of the ultraviolet lamp 310 supported by the partition wall 130 among the ballast water flowing in the body 10) Which has not been directly irradiated with ultraviolet rays Host the number is characterized in that to prevent the same outflow through the outlet (125).

1 and 38, the internal space of the body 1001 is partitioned by a partition wall 1003 for partitioning a space through which the ballast water flows and a space through which the ballast water flows, and in addition, Both ends of the ultraviolet lamp 1002 arranged in the vertical direction with respect to the flow direction of the ballast water flowing in the ultraviolet lamp 1001 are coupled to and supported by the partition 1003 on both sides, The electrode 10021 for generating ultraviolet rays is positioned at a position where the ultraviolet rays are not radiated near the electrode 10021 and the electrode 10021 protrudes by a predetermined length from the partition 1003 toward the space where the ballast water flows . 38, in the ballast water flow in the body 1001, the flow of the ballast water flowing in a straight line along both side partition walls 1003 of the ballast water introduced through the inlet portion (d) The ultraviolet rays do not directly receive the ultraviolet rays while passing through only the portions of both electrodes 10021 of the ultraviolet lamp 1002. Therefore, the effect of sterilizing treatment by ultraviolet rays is lowered, and thus the microorganisms included in the ballast water flow are untreated There is a problem that a problem of leakage occurs.

38, both ends of the ultraviolet lamp 1002 and a driving motor and the like are located in a space defined by the partition wall 1003 where the ballast water does not flow At this time, in the case of a space for accommodating a bulky driving motor, the space has a diameter equal to the diameter of the body 1001, and extends to a length enough to cover the entire distal end of the driving motor, thereby occupying a large volume. However, due to the characteristics of the ultraviolet ray treatment apparatus installed in a limited space called a vessel, when the ultraviolet ray treatment apparatus has an excessively large volume, space occupied in a limited space called a vessel is increased, resulting in an inefficient problem.

Accordingly, in the present invention, as shown in FIG. 3, FIG. 4, FIG. 39, and FIG. 40, among the flows of ballast water flowing in the body 10, the partition walls 130 The flow of the ballast water passing through the electrode 311 formed on both ends of the ultraviolet ray lamp 310 without being directly irradiated with the ultraviolet rays is transmitted to the protruding blade 160 near the outflow portion 125 The ultraviolet rays are directly irradiated by the ultraviolet ray lamp 310 in the vicinity of the ultraviolet ray irradiated portion and can be discharged through the outflow portion 125.

39, the protruding vane plate 160 is a generally cylindrical shape having a predetermined length protruding from the inner side surface of the body 10 and surrounding the entirety of the outflow portion 125 (formed in a generally cylindrical shape) As a result of the existence of the protruding vane plate 160, the ballast water flowing through the inflow part 124 moves linearly along both side walls 130 of the ballast water, The flow of the ballast water that passes through only the portions of the both side electrodes 311 of the first and second electrodes 310 and 310 is not directly discharged through the outflow portion 125 but collides against the protruding blade 160 at the outflow portion 125 The flow of the ultraviolet ray is reversed and the ultraviolet ray is directly irradiated to the portion of the ultraviolet ray lamp 310 adjacent to the outflow portion 125 that is not the electrode 311. That is, Fu Da And then flows out through the outflow portion 125. Accordingly, the protruding blade 160 prevents the ballast water not directly irradiated with ultraviolet rays from flowing out through the outflow part 125, thereby enhancing ultraviolet treatment efficiency. The diameter D1 of the protruding blade 160 is equal to or larger than the diameter D2 of the outlet 125 and is equal to or less than the distance D3 between the two electrodes 311 of the ultraviolet lamp 310 .

40, in the body 10, a second wing plate 161 which surrounds the inflow portion 124 through which the ballast water flows in the body 10 and protrudes by a predetermined length, So that the flow of the ballast water flowing through the inflow portion 124 is reduced toward the vicinity of the electrode 311 at both ends of the ultraviolet lamp 310 along the partition wall 130 immediately after the inflow can do. The second wing plate 161 has a configuration similar to the protruding wing plate 160 described above but differs from the second wing plate 161 in that the forming position thereof is around the inflow portion 124, The flow of the ballast water flowing through the inflow portion 124 can be controlled by the flow of the inflow portion 124 in the case where there is no configuration similar to that of the second wing plate 161, There is a high possibility that the ballast water flowing adjacent to the inner circumferential surface of the ultraviolet lamp 124 is directed immediately to the vicinity of the electrodes 311 at both ends of the ultraviolet lamp 310 along the partition wall 130 immediately after the inflow of the ballast water. The flow is guided by the second wing plate 161 toward the center portion rather than the both side walls 130 of the body 10 immediately after the introduction through the inlet portion 124. Therefore, The inflow of ballast water has at least an ultraviolet ray The ultraviolet ray treatment efficiency can be further increased by passing the portion of the lamp 310 that is not the electrode 311, that is, a portion directly irradiated with ultraviolet rays.

39 and 3800, the space (the first space 133 and the second space 133) formed on both sides of the body 10 separated by the partition 130 into a space in which the ballast water does not flow in the body 10, (Volume) of the ultraviolet lamp 310 or the driving shaft 540 is minimized so that the size of the ultraviolet lamp 310 or the driving shaft 540 is smaller than the space of the one side of the body 10 The driving motor 550 having a large length is accommodated in the motor receiving portion 170 formed outside the body 10 so as to accommodate the driving motor 550 separately. So that the ultraviolet processing apparatus occupies less space in the limited space of the ship. That is, the total volume of the spaces on both sides of the body 10 minimized to the size (volume) for accommodating both ends of the ultraviolet lamp 310 and the driving shaft 540 and the volume of the space of the motor receiving portion 170, It is possible to significantly reduce the volume compared to the sum of the space volume on both sides of the body 1001 formed to have a length long enough to accommodate the driving motor in the conventional ultraviolet processing apparatus and a correspondingly large volume.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Should be interpreted as belonging to the scope.
