The portion of the drive motor for rotation and automatic opening and closing valve to open for a constant cooling, characterized in that the foreign material of the strainer and a control unit to ensure that leakage to the sea water outlet pipe seawater foreign matter automatic removing apparatus for maryeonham.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

EXAMPLE

As shown in FIG. 2 and FIG. 3, the apparatus for automatically removing seawater foreign matter for cooling water according to the present invention 1 is equipped with a conical mesh strainer 5 on the seawater inlet pipe 104 side. The strainer 5 has a structure that can be exchanged with respect to the seawater inlet pipe 104, and the pressure detecting unit for detecting the pressure difference before and after the strainer 5 on the front and rear sides of the strainer 5 ( 10, the pressure detection unit 10 is connected to the seawater inlet pipe 104, a plurality of pressure detection pipe (12a) (12b) for detecting the pressure, and the pressure detection pipe (12a) (12b) It has a differential pressure transmitter (15) for transmitting the pressure difference obtained in the electrical signal. The differential pressure transmitter 15 is configured to be electrically connected to the control unit 40 to be described later, so that the electrical differential pressure signal is applied.

In addition, when the foreign matter is deposited on the strainer 5, the cleaning unit 20 is provided to automatically remove the bar, the cleaning unit 20 is a cleaning brush that rotates along the inner conical surface of the strainer ( 22, which is mounted with two up and down hairbrushes 24a and 24b, as shown in FIG. 4, and connected to a motor 26 for rotating the cleaning brush 22. will be.

The cleaning brush 22 and the motor 26 are connected to each other by the motor 26, which is located outside the seawater inlet pipe 104, and the rotary shaft 28 extends inside the seawater inlet pipe 104. It enters into the casing 30 and is connected to the central shaft 22a extending from the cleaning brush 22 through the bevel gear pairs 32a and 32b at the bent portion 31 of the B-shaped casing 30. . In addition, the rotation shaft 28 and the central shaft 22a are rotatably connected to the casing 30 through a plurality of bearing members 34, and the casing 30 is inside the seawater inflow pipe 104. The position is fixed through the support 36, and thus, the operation of the drive motor 26 is performed through the rotary shaft 28, the bevel gears 32a, 32b, and the central shaft 22a. The cleaning brush 22 in contact with the inner surface of the) is to be rotated.

And, having a foreign material discharge pipe 37 connecting the rear end side of the strainer (5) and the seawater discharge pipe 106, the foreign material discharge pipe 37 extends outward through the seawater inlet pipe 104 and the seawater inlet pipe On the outside of the 104, an automatic switching valve 37a which is automatically turned on and off by the controller 40 to be described later is provided.

On the other hand, if the strainer 5 is clogged by foreign matter, according to the differential pressure signal provided from the pressure detector 10, the control unit 40 to remove the foreign matter deposited on the strainer 5 is a drive motor of the cleaning unit 20 It is electrically connected to (26), and has a structure that is electrically connected to the automatic opening and closing valve (37a), which can be embedded in a control panel (not shown) for automatically controlling the purified water cooling device (100).

Effects of the configuration and operation of the present invention are as follows.

Automatic removal of seawater foreign matter for cooling water according to the present invention (1) is a high temperature purified water is introduced into the hollow body 102 from the purified water inlet pipe 112, the low temperature through the seawater inlet pipe 104 When the seawater is introduced, it absorbs the high temperature heat of the purified water flowing outside the seawater flow tube 110 in the process of flowing out of the seawater flow tube 110 to the outside through the seawater discharge pipe 115, The low temperature purified water thus lowered is discharged to the outside through the purified water discharge pipe 116.

However, when foreign matter is introduced into the seawater inlet pipe 104 in this operation process, it is caught by the strainer 5, and when such foreign matter is deposited, it blocks the flow of seawater through the strainer 5. In this case, a differential pressure is generated in the pressure detecting pipes 12a and 12b of the pressure detecting unit 10, which is a high pressure detected at the front side of the strainer 5, and a low pressure at the rear side of the strainer 5. The differential pressure signal is detected and provided to the differential pressure transmitter 15, and the differential pressure signal is converted into an electrical signal by the differential pressure generator 15 and transmitted to the controller 40.

When the differential pressure signal continuously input exceeds the preset reference value, the controller 40 operates by supplying electricity to the driving motor 26 of the cleaning unit 20 and at the same time the foreign matter discharge pipe 37 The automatic opening and closing valve 37a will be opened.

In this case, the operation of the drive motor 26 rotates the cleaning brush 22 through the rotating shaft 28, the bevel gear pairs 32a, 32b, and the central shaft 22a, and the cleaning brush 22 The upper and lower hair brushes 24a and 24b provided at the upper surface are rotated along the inner surface of the conical strainer 5 to wipe off foreign substances.

The foreign matters separated from the strainer 5 are discharged to the seawater discharge pipe 116 through the foreign matter discharge pipe 37 in which the automatic opening and closing valve 37a is opened, which is the seawater flowing out through the seawater discharge pipe 116. Since the suction speed is generated at the tip of the foreign substance discharge pipe 37 due to the flow rate, foreign substances separated from the strainer 5 are easily discharged to the seawater discharge pipe 106 through the foreign substance discharge pipe 37.

Therefore, when the foreign matters are removed, the flow resistance of the seawater through the strainer 5 is reduced, so that the smooth seawater flows, and in this case, the strength of the differential pressure signal provided from the differential pressure transmitter 15 is reduced. As a result, the control unit 40 accordingly stops the operation of the drive motor 26 and closes the automatic opening / closing valve 37a to return to its original state to achieve normal operation.

As described above, according to the present invention, when the strainer 5 blocks the foreign matters of the seawater from flowing into the inside of the apparatus, and the foreign matter is filtered by the strainer 5, the foreign matters are automatically discharged to the outside. The improved effect is obtained to improve durability, improve productivity of maintenance work, and enable stable operation of the equipment.
