[0030] A filter component for a circulating cooling water system, such as Figure 1-Figure 3As shown, it includes a filter box 10 for a circulating cooling water system, a replaceable filter mechanism 20 is installed on the top of the filter box 10, a water inlet pipe 30 connected to the inside of the replaceable filter mechanism 20 is installed on one side of the filter box 10, and a drain pipe 40 is installed at the bottom of the filter box 10; the replaceable filter mechanism 20 includes a filter screen cartridge 21 installed in the filter box 10 and a fixed top seat 22 plugged into the top of the filter box 10, the four top corners of the top surface of the fixed top seat 22 are connected to the top surface of the filter box 10 by locking bolts 23, and an internal threaded pipe 24 coaxial with the water inlet pipe 30 is embedded on the outer wall of one side of the filter screen cartridge 21; a threaded pipe 24 having a size suitable for the internal threaded pipe 24 is installed at the end of the water inlet pipe 30 The filter assembly is equipped with a connector 31 that is threadedly connected. The design of the replaceable filter mechanism 20 makes it convenient to replace the filter material. When the filter screen cartridge 21 is blocked or the filtering effect is poor, the fixing top seat 22 can be removed from the filter box 10 by unlocking the locking bolt 23, and then a new filter screen cartridge 21 can be replaced, thereby improving the maintainability and service life of the filter assembly. The internal threaded tube 24 embedded on the outer wall of one side of the filter screen cartridge 21 is connected to the connector 31 at the end of the water inlet pipe 30 by a threaded connection. This connection method is simple and reliable, and is easy to install and disassemble. At the same time, it can also ensure the sealing between the water inlet pipe 30 and the filter screen cartridge 21 to prevent water leakage from the connection.

[0031] Furthermore, a stand 11 that can be raised and lowered is installed at the bottom center of the filter box 10, and a fixed base 12 is coaxially connected to the bottom of the stand 11. The bottom area of ​​the fixed base 12 is larger than the bottom area of ​​the filter box 10.

[0035] Working principle of the filter components of this circulating cooling water system:

[0036] 1. Installation and preparation stage:

[0037] The filter box 10 is installed at an appropriate position in the circulating cooling water system. The water inlet pipe 30 is connected to the water source of the circulating cooling water system to ensure smooth water flow. The drain pipe 40 is connected to the drain outlet of the circulating cooling water system to discharge the filtered water.

[0038] 2. Install the replaceable filter mechanism 20:

[0039] Insert the filter screen cartridge 21 into the filter box 10, and ensure that the filter screen cartridge 21 is in the correct position. Place the fixed top seat 22 on the top of the filter box 10 so that it corresponds to the filter screen cartridge 21. Tightly connect the fixed top seat 22 to the top surface of the filter box 10 through the locking bolts 23 to ensure that the filter screen cartridge 21 is fixed in the filter box 10.

[0040] 3. Connect the water inlet pipe 30:

[0041] Align the end of the water inlet pipe 30 with the internal threaded pipe 24 on the outer wall of one side of the filter screen cylinder 21. Rotate the end of the water inlet pipe 30 to make it threadedly connected with the internal threaded pipe 24 to ensure that the connection is tight and leak-proof.

[0042] 4. Operation and Filtering:

[0043] The circulating cooling water system is started, and the water flows into the filter screen cylinder 21 through the water inlet pipe 30. The filter material in the filter screen cylinder 21 captures and filters impurities and particulate matter in the water. The filtered water passes through the filter screen cylinder 21 and the bottom of the filter box 10, and is finally discharged from the drain pipe 40.
