Description

냉각팬용 날개 각도 조절장치{Fan angle control apparatus for cooling fan}Fan angle control apparatus for cooling fan

본 발명은 냉각팬용 날개 각도 조절장치에 관한 것으로서, 더욱 상세하게는 열연공장 수처리 설비에 있어서 냉각수를 재처리하는 공정 중 냉각탑(COOLING TOWER)에 설치되어 냉각수의 수온관리를 행하는 냉각팬용 날개의 각도를 변화시켜 공기와 날개의 접촉면에 따라서 냉각량을 조절할 수 있는 냉각팬용 날개 각도 조절장치에 관한 것이다.The present invention relates to a vane angle control device for a cooling fan, and more particularly, to an angle of a cooling fan blade installed in a cooling tower during a process of reprocessing cooling water in a water treatment facility of a hot rolling mill to perform water temperature management of the cooling water. The present invention relates to a blade angle adjusting device for a cooling fan that can be changed to adjust the amount of cooling according to the contact surface of air and the blade.

일반적으로 제철소의 압연공정에서 사용되고 회수(RETURN)되어 나오는 물은 필터(FILTER)를 통해 소정의 수질을 확보하여 수온관리를 위해 냉각탑으로 송수되고 수온이 높을 경우 냉각팬을 동작시켜 수온을 낮추게 된다.In general, the water used in the rolling process of the steel mill and returned (RETURN) is to secure a predetermined water quality through a filter (FILTER) to be sent to the cooling tower for water temperature management and to lower the water temperature by operating a cooling fan when the water temperature is high.

종래의 냉각수단은 도 1에 나타낸 바와 같이 냉각탑(1)의 상부 일측에 구동모터(2)가 설치되고 그 구동모터(2)의 회전축(3)에는 회전속도를 감속시키는 감속기(4)가 설치되어 있으며 그 감속기(4)의 출력축(5)에는 상/하부 플레이트(6)(7)가 설치되어 있다.In the conventional cooling means, as shown in FIG. 1, a driving motor 2 is installed at an upper side of the cooling tower 1, and a reduction gear 4 for reducing the rotation speed is installed at the rotation shaft 3 of the driving motor 2. The upper and lower plates 6 and 7 are provided on the output shaft 5 of the reducer 4.

상기 상/하부 플레이트(6)(7)의 사이에는 냉각탑(1) 내부의 공기를 외부로 배출시키는 복수개의 날개(8)가 소정의 경사각을 이루며 설치되어 있다.Between the upper and lower plates 6 and 7, a plurality of vanes 8 for discharging air inside the cooling tower 1 to the outside are formed at a predetermined inclination angle.

따라서 냉각탑(1) 내부의 온도를 낮추기 위해서는 구동모터(2)를 구동시켜그 구동모터(2)에서 발생되는 회전력을 회전축(3)을 통하여 감속기(4)로 전달한다.Therefore, in order to lower the temperature inside the cooling tower 1, the driving motor 2 is driven to transmit the rotational force generated by the driving motor 2 to the reducer 4 through the rotation shaft 3.

회전력을 전달받은 감속기(4)는 입력되는 회전속도를 내부에 설치된 감속기어의 비율에 따라 속도를 감속시켜 상부에 설치된 출력축(5)을 회전시키게 된다.The speed reducer 4 receiving the rotational force reduces the speed according to the ratio of the speed reduction gear installed therein to rotate the output shaft 5 installed above.

상기 출력축(5)이 회전하게 되면 그 출력축에 설치된 상/하부 지지플레이트(6)(7)와 날개(8)가 함께 회전되면서 냉각탑(1) 내부의 공기를 외부로 배출시키면서 냉각탑(1) 내의 온도를 낮추게 되는 것이다.When the output shaft 5 rotates, the upper / lower support plates 6 and 7 and the blades 8 installed on the output shaft rotate together, while discharging the air inside the cooling tower 1 to the outside, and the inside of the cooling tower 1. It will lower the temperature.

이때 압연라인으로 공급되는 냉각수의 온도값를 측정하여 그 온도값이 설정치 온도값보다 높을 경우에는 냉각팬을 연속적으로 회전시키고 상기 냉각팬의 연속적인 작동에도 냉각수의 온도값이 올라가면 냉각팬의 속도 빨라지도록 구동모터(2)의 회전수를 증가시킨다.At this time, if the temperature value of the cooling water supplied to the rolling line is measured and the temperature value is higher than the set point temperature value, the cooling fan is continuously rotated and the cooling fan speed is increased if the temperature value of the cooling water rises even in the continuous operation of the cooling fan. The rotation speed of the drive motor 2 is increased.

그리고 상기 냉각수의 측정 온도값이 설정치 온도값보다 낮아질 경우에는 증가된 구동모터(2)의 회전수를 감소시키는 것으로 압연라인으로 공급되는 냉각수의 온도를 조절하게 되는 것이다.And when the measured temperature value of the coolant is lower than the set point temperature value is to control the temperature of the coolant supplied to the rolling line by reducing the number of revolutions of the increased drive motor (2).

그러나 이와 같은 종래의 냉각팬의 날개는 고정되어 있으므로 도 2에 나타낸 바와 같이 날개와 공기가 접촉되는 풍량 접촉면이 일정하여 냉각효율을 향상시키기 위해서는 반드시 냉각팬의 회전속도를 증가시켜야 하므로 인하여 고속 회전에 따르는 전력소비가 증가하게 된다.However, since the blade of the conventional cooling fan is fixed, as shown in FIG. 2, the air flow contact surface between the blade and the air is constant so that the rotation speed of the cooling fan must be increased to improve the cooling efficiency. The power consumption that follows increases.

또한 속도의 변화시 발생되는 충격력이 감속기 및 설비에 전달되어 편심에 의한 불균형이 발생하고 심할 경우에는 감속기가 파손되어 사용수명을 단축시키게 되는 문제점이 있었다.In addition, the impact force generated during the change of speed is transmitted to the reducer and the equipment, an imbalance caused by the eccentricity occurs, and in the case of severe damage, the reducer is damaged and shortened the service life.

본 발명은 상기한 문제점 해결하기 위하여 발명한 것으로서, 그 목적은 압연라인으로 공급되는 냉각수의 온도를 낮추기 위하여 냉각탑의 상부에서 회전되는 냉각팬의 날개의 각도를 조절하여 동일한 회전속도를 증가시키기 않고도 냉각효율을 향상시킬 수 있는 냉각팬용 날개 각도 조절장치를 제공함에 있다.The present invention has been invented to solve the above problems, the object of the cooling is to adjust the angle of the blade of the cooling fan rotated at the top of the cooling tower to lower the temperature of the cooling water supplied to the rolling line without increasing the same rotational speed It is to provide a wing angle control device for the cooling fan that can improve the efficiency.

이와 같이 구성된 본 발명의 작용을 상세히 설명하면 다음과 같다.Referring to the operation of the present invention configured as described in detail as follows.

압연라인으로 송수되는 냉각수의 온도값이 초기에 설정된 온도값보다 높을 경우에는 구동모터(2)를 구동하며 이때 구동모터(2)에서 발생되는 회전력은 감속기(4)에서 감속된 후 그 감속기(4)의 출력축(5)을 회전시키게 되며 상기 출력축(5)이 회전됨에 따라 그 출력축(5)에 결합된 상/하부 지지플레이트(6)(7) 사이의 날개(8)가 회전하면서 냉각탑(1) 내부의 공기를 외부로 배출시키면서 냉각탑(1) 내부를 냉각시키게 된다.When the temperature value of the cooling water sent to the rolling line is higher than the initially set temperature value, the driving motor 2 is driven. At this time, the rotational force generated by the driving motor 2 is decelerated by the reducer 4 and then the reducer 4 And rotates the output shaft (5) of the cooling shaft (1) as the blade (8) between the upper and lower support plates (6) (7) coupled to the output shaft (5) as the output shaft (5) is rotated The cooling tower 1 is cooled while discharging the air inside.

이때 유압펌프(12)는 아이들 기어(10)와 종동기어(11)를 통해서 전달되는 회전력에 의해서 작동되지만 그 유압펌프(12)에 설치된 밸브(15)는 닫혀진 상태이므로 승강 실린더(14)는 작동되지 않게 되므로 날개(8)는 도 4 및 도 5에 나타낸 바와 같이 접촉면이 감소된 상태로 회전하게 되는 것이다.At this time, the hydraulic pump 12 is operated by the rotational force transmitted through the idle gear 10 and the driven gear 11, but the lifting cylinder 14 is operated because the valve 15 installed in the hydraulic pump 12 is closed. Since the wing 8 is not rotated as shown in Figures 4 and 5, the contact surface is reduced.

또한, 상기 회전원판(18)은 상/하부 플레이트(6)(7)와 함께 회전하게 되며 회전원판(18)의 저면에는 아이들 롤(17)이 접촉되어 있으므로 원활하게 회전되면서 냉각탑(1) 내부의 공기를 외부로 배출시키는 것이다.In addition, the rotating disc 18 rotates together with the upper / lower plates 6 and 7, and the idle roll 17 is in contact with the bottom of the rotating disc 18, thereby smoothly rotating the inside of the cooling tower 1. To let the air out.

이와 같이 회전되는 날개에 의해서 냉각탑(1)내부의 공기가 외부로 배출되어도 냉각수의 온도가 낮아지지 않을 경우에는 유압펌프(12)에 설치된 밸브(15)를 개방시킨다.When the air inside the cooling tower 1 is discharged to the outside by the blades rotated as described above, when the temperature of the cooling water is not lowered, the valve 15 installed in the hydraulic pump 12 is opened.

상기 밸브(15)가 개방되면 유압펌프(12)는 유압유 탱크(13)에 보관된 유압유를 펌핑하여 승강 실린더(14) 측으로 공급하게 되므로 상기 승강 실린더(14)는 상부로 상승하게 된다.When the valve 15 is opened, the hydraulic pump 12 pumps the hydraulic oil stored in the hydraulic oil tank 13 to be supplied to the lifting cylinder 14 side, so that the lifting cylinder 14 is raised upward.

상기 승강 실린더(14)가 상승하게 되면 그 상측에 설치된 회전원판(18)을 상승시키게 되고 그 회전원판(18)의 상부에 결합된 작동로드(19)와 가이드봉(20)이 함께 상승하게 되는 것이다.When the elevating cylinder 14 is raised to raise the rotary disk 18 installed on the upper side and the operating rod 19 and the guide rod 20 coupled to the upper portion of the rotary disk 18 is raised together will be.

상기 작동로드(19)가 상승되면 그 상단부에 힌지 결합된 회동부재(22)가 회전하게 됨에 따라 날개(8)는 도 6 및 도 7에 나타낸 바와 같이 회동되는 것이다.When the working rod 19 is raised, as the rotating member 22 hinged to the upper end rotates, the blade 8 is rotated as shown in FIGS. 6 and 7.

즉, 상기 날개(8)가 공기와 접촉면이 증가되도록 각도가 변경된 상태에서 회전되므로 많은 양의 공기가 외부로 배출되므로 냉각효율이 향상되는 것이다.That is, since the wing 8 is rotated in a state in which the angle is changed so that the contact surface with the air increases, a large amount of air is discharged to the outside to improve the cooling efficiency.

그리고 측정되는 냉각수의 온도값이 설정값보다 낮게되면 공기와 날개(8)의 접촉면이 감소시키면 되는 것이며 이때에는 승강 실린더(14)가 하부로 이동되도록 밸브(15)의 방향을 변경하면 회전원판(18)은 가이드봉(20)에 끼워진 스프링(21)의 복원력에 의해서 하부로 이동하게 된다.If the measured temperature of the coolant becomes lower than the set value, the contact surface between the air and the blade 8 may be reduced. In this case, when the direction of the valve 15 is changed to move the lifting cylinder 14 downward, the rotating disc ( 18 is moved downward by the restoring force of the spring 21 fitted to the guide rod (20).

또는 상기 날개(8)와 공기의 접촉면이 증가되도록 날개(8)가 회동된 상태에서도 냉각수의 온도값이 설정값보다 높을 경우에는 구동모터(2)의 회전수를 증가시켜 감속기(4)의 출력축(5)으로 출력되는 회전속도를 빠르게 하여 날개(8)에 의해서 많은 양의 공기를 배출시키면 냉각수의 온도가 낮아지게 되는 것이다.Alternatively, when the temperature of the coolant is higher than the set value even when the blade 8 is rotated to increase the contact surface between the blade 8 and the air, the output shaft of the reducer 4 is increased by increasing the rotation speed of the drive motor 2. By discharging a large amount of air by the blade (8) by increasing the speed of rotation output to (5) is the temperature of the cooling water is lowered.

이와 같은 본 발명은 냉각수의 온도에 따라 냉각탑의 상부에 설치되어 회전되는 냉각팬 날개의 각도를 조절하게 됨에 따라 그 날개와 접촉되는 공기의 접촉면을 변경시키게 되므로 동일한 회전속도에서도 냉각효율이 향상되는 것이다.Such the present invention is to adjust the angle of the cooling fan blade is rotated installed on the top of the cooling tower according to the temperature of the cooling water to change the contact surface of the air in contact with the blade is to improve the cooling efficiency at the same rotational speed .

또한, 회전속도의 변경에 따른 충격력 발생을 방지하여 감속기 및 설비의 손상을 최소화하여 사용수명을 연장시킬 수 있게 되는 특유의 효과가 있다.In addition, there is a peculiar effect that can prevent the impact force caused by the change of the rotation speed to minimize the damage to the reducer and equipment to extend the service life.
