The transmission shaft 39 may be connected to the gear housing 13.

The bolt part 35 may be located along the circumference of the rotation shaft 33. The bolt part 35 may include a plurality of bolts 35a and 35d. The sensor 37 may be located below the rotation shaft 33. When the rotating shaft 33 is rotated by the motor 31, the sensor 37 may detect a plurality of rotating bolts (35a, 35d). The sensor 37 may detect the proximity state of the plurality of bolts 35a and 35d. The sensor 37 may detect the number of proximity of the plurality of bolts 35a and 35d rotating within a predetermined time.

The controller 40 may include a terminal box 41 and a connection line 43. The connection line 43 may electrically connect the sensor 37 and the terminal box 41. The controller 40 may control the rotation direction of the motor 31 according to the signal of the sensor 37. The controller 40 may generate an alarm according to the signal of the sensor 37.

When a large amount of foreign matter is laminated to the bucket portion 25, the rotational movement of the bucket portion 25 and the rotational movement of the rotary shaft 33 is stopped, so that the sensor portion 37 is a plurality of bolts (35a, 35d) within a predetermined time The number of times cannot be detected. The controller 40 may control the motor 31 to rotate in the direction opposite to the arrow if the plurality of bolts 35a and 35d are not detected a predetermined number of times within a predetermined time. When the motor 31 rotates in the opposite direction to the arrow, the bucket part 25 rotates in the opposite direction along the first frame 11 so that the foreign matter in the unblocked part may be removed to avoid the area blocked by excessive foreign matter.

3 is a partial yz cross-sectional view of the sensing unit 30 and the control unit 40 of FIG. 2. As shown in FIG. 3, the bolt part 35 may include a plurality of bolts 35a, 35b, 35c, 35d, 35e, and 35f. The plurality of bolts 35a, 35b, 35c, 35d, 35e, and 35f may be spaced apart from each other along the circumference of the rotation shaft 33. The sensor 37 may detect the plurality of bolts 35a, 35b, 35c, 35d, 35e, and 35f that rotate in accordance with the rotation of the rotation shaft 33 by the number of times of proximity within a predetermined time.

When the rotating shaft 33 rotates 10 times in 60 seconds in the direction of the arrow in FIG. 3, the sensor 37 may rotate 1/6 in 1 second, and thus the sensor 37 may include a plurality of bolts 35a, 35b, 35c, 35d, 35e, and 35f. Can be detected once per second. For example, the sensor 37 detects the bolt 35d of the rotating shaft 33 and the bolt 35c after 1 second, and sequentially turns the bolts 35b, 35a, 35f, and 35e in units of 1 second. ) Can be detected.

When the rotation of the bucket part 25 is stopped due to the lamination of a large amount of foreign matter, the rotation of the rotation shaft 33 is also stopped, so that the sensor 37 is provided with a plurality of bolts 35a, 35b, 35c, 35d, 35e, 35f) cannot be detected. When the rotation of the rotating shaft 33 is stopped and the sensor 37 does not detect the plurality of bolts 35a, 35b, 35c, 35d, 35e, and 35f for more than 3 seconds, the controller 40 may rotate the rotating shaft ( The direction of rotation of 33 can be controlled in the direction opposite to the arrow.

When the rotary shaft 33 is stopped, the foreign material remover 1 may not be able to detect the bolt part 35, thereby controlling the direction of the motor 31 in reverse to prevent damage to the motor 31. In addition, the foreign matter remover 1 can stably supply cooling water to a heat exchanger provided in an industrial facility while removing foreign substances from the bucket part 25, thereby preventing work stoppage of the industrial facility.

However, in the related art, when excessive foreign matter is introduced and the rotational movement of the removal device is stopped, the motor is overloaded and the motor is broken to stop the operation of the facility and replace the motor.

4 shows a perspective view of the foreign matter remover 2 according to the embodiment of the present invention. Since the foreign material remover 2 of FIG. 4 is similar to the foreign material remover 1 of FIG. 1, the same reference numerals are used for the same parts, and a detailed description thereof will be omitted.

As illustrated in FIG. 4, the foreign material remover 2 may include a main body 10, a remover 20, a detector 30, and a controller 40. The removal part 20 may include a support part 22, a screen part 24, a bucket part 25, and a fixing part 27.

The support part 22 may include a fourth support part 22a and a fifth support part 22b. The fourth support part 22a and the fifth support part 22b may be connected to the gear housing 13. The fourth support part 22a and the fifth support part 22b may be spaced apart from the plurality of side surfaces of the gear housing 13. The fourth support part 22a and the fifth support part 22b may be radially positioned about the gear housing 13.

Since the fourth support part 22a and the fifth support part 22b are spaced apart from each other in a plurality, the foreign matter contained in the coolant can be effectively separated by modifying the flow of the coolant into a vortex. Therefore, since the amount of foreign matter stacked on the screen unit 24 can be minimized, the occurrence rate of malfunction of the foreign matter remover 2 can be reduced.

Upper portions of the fourth support part 22a and the fifth support part 22b may have a shape inclined in an inner direction of the main body part 10. The foreign matter of the coolant is guided to the outer direction of the main body 10 by the rotational centrifugal force of the first frame 11 and also in the inner direction of the main body 10 along the inclined upper shapes of the supporting parts 22a and 22b. Can be induced.

Therefore, since the turbulent fluid flow can be generated by inducing irregular movement of the foreign matter of the cooling water, separation of the cooling water and the foreign matter can be easily performed, thereby increasing the filtration or removal efficiency of the removing unit 20.

The screen part 24 may be positioned between the fourth support part 22a and the fifth support part 22b. One side of the screen part 24 may be connected to the side of the fourth support part 22a. The other side of the screen part 24 may be connected to the side of the fifth support part 22b. The screen portion 24 may have a circular arc shape. When the screen portion 24 has an arc shape, the area for filtering foreign matters is increased, so that a larger amount of foreign matters can be removed, thereby increasing the efficiency of the removal unit 20.

The fixing part 27 may include a first fixing surface 271, a second fixing surface 273, a third fixing surface 275, and a fourth fixing surface 277. The first fixing surface 271 may be connected to the fourth support part 22a. The first fixing surface 271 may fix one side of the screen portion 24 to the fourth support portion 22a. The second fixing surface 273 may fix the other side of the screen part 24 to the fifth support part 22b.

The third fixing surface 275 may be located between the first fixing surface 271 and the second fixing surface 273. The third fixing surface 275 may connect the first fixing surface 271 and the second fixing surface 273. The fourth fixing surface 277 may be located above the third fixing surface 275. The fourth fixing surface 277 may be connected to the third fixing surface 275 and have an arc shape. Since the fourth fixing surface 277 may be in contact with the arc shape of the screen portion 24, the fourth fixing surface 277 may firmly support the screen portion 24.

The foreign material remover 2 has a plurality of screens 24 positioned between the plurality of support parts 22a and 22b, respectively, and thus, when an abnormality occurs in the screen part 24, only the corresponding parts may be replaced or repaired. Can reduce the administrative cost.
