Technical Field
[0001] This utility model relates to the field of circulating water descaling technology, and in particular to a cooling circulating water descaling device. Background Technology
[0002] Cooling circulating water refers to water that is circulated in a cooling system. It is typically used to cool electrical equipment, industrial machinery, buildings, and other facilities that require heat dissipation. Cooling circulating water absorbs heat from the heat dissipation equipment and carries it out of the equipment. It is then cooled by a cooler or cooling tower and re-injected into the equipment to maintain the normal operating temperature of the equipment. Scale will form in cooling circulating water. The scale in cooling circulating water is formed by the combination of dissolved oxygen, ions, and microorganisms in the water at high temperatures. After long-term use, it may cause problems such as corrosion and blockage of the equipment.
[0003] Existing cooling water descaling devices work by filtering cooling water through a filter screen as it flows through the system. The filter screen, with its specific pore structure, intercepts impurities and scale larger than the pore size in the water, thus achieving the initial removal of scale and maintaining the relative cleanliness of the cooling water to ensure the normal operation of subsequent stages of the cooling circulation system.
[0004] However, with prolonged filtration, dirt in the cooling water will gradually accumulate on the filter screen. Once too much dirt accumulates, it may clog the filter screen, affecting its normal filtration function. It may even have a negative impact on the overall performance of the cooling circulation system, and may also cause abnormal pressure increases within the system, placing an additional burden on the pipes, pumps, and other equipment in the system. This will have a serious negative impact on the overall performance of the cooling circulation system, reducing the system's operating efficiency and lifespan, and increasing equipment maintenance costs and the risk of failure.

A first spring 805 is provided on the inner side of the top cover 3. A slide rod 806 is fixedly connected to one side of the first spring 805. A connecting plate 807 is fixedly connected to one side of the slide rod 806. A cleaning brush 808 for brushing off dirt from the filter screen 801 is fixedly connected to one side of the connecting plate 807. The cleaning brush 808 abuts against the inner wall of the filter screen 801. A filter fixing assembly is provided on one side of the top cover 3. The filter fixing assembly includes a connecting ring 809. A connecting ring 809 is fixedly connected to one side of the filter screen 801. A first sealing ring 810 is provided between the connecting ring 809 and the top cover 3. A second sealing ring 811 is provided below the filter screen 801. A fixing ring 812 is fixedly connected to one side of the top cover 3. A second spring 813 is provided inside the fixing ring 812. A fixed ring 812 is fixed to one side of the second spring 813. A slider 814 is connected, with a locking block 815 fixedly connected to one side of the slider 814 and a pull rod 816 fixedly connected to one side of the slider 814. Multiple sets of fixing frames 804 are arranged in a circumferential array outside the rotating rod 803. The multiple sets of fixing frames 804 allow multiple sets of first springs 805, sliding rods 806, connecting plates 807, and cleaning brushes 808 to be mounted on the fixing frames 804, thus improving the efficiency and effectiveness of cleaning the inner wall of the filter screen 801. A groove is provided on the fixing frame 804, through which the sliding rod 806 is slidably connected to the inner side of the fixing frame 804, thus guiding and limiting the sliding rod 806. The fixed ring 812 has a second groove, and the slider 814 is slidably connected to the inner side of the fixed ring 812 through the second groove. The groove on the fixed ring 812 allows the slider 814 to slide smoothly within the fixed ring 812, thus guiding and limiting the slider 814. The first sealing ring 810 and the second sealing ring 811 seal the filter screen 801 to prevent dirt from entering the descaling cylinder 1. Cooling circulating water enters the inner side of the filter screen 801 through the inlet pipe 4, where the filter screen 801 intercepts dirt in the cooling circulating water. The cooling circulating water then passes through the filter screen 801 into the descaling cylinder 1 and is finally discharged through the outlet pipe 5. Starting the drive motor 802 causes the rotating rod 803 to rotate.Rotating rod 803 drives fixed frame 804 to rotate. First spring 805 provides elastic support for sliding rod 806. Sliding rod 806 drives cleaning brush 808 to abut against the inner wall of filter screen 801 via connecting plate 807. Fixed frame 804 drives sliding rod 806 to rotate, and sliding rod 806 drives cleaning brush 808 to rotate via connecting plate 807, thereby brushing away dirt from the inner wall of filter screen 801. Then, electric valve 7 is activated, and dirt is discharged through drain pipe 6. When replacing filter screen 801, top cover 3 is opened, and then pull rod 816 is pulled. Pull rod 816 drives slider 814 to move. The slider 814 presses against the second spring 813, causing the slider 814 to move the locking block 815, disengaging it from the connecting ring 809 and releasing its restraint. Then, the connecting ring 809 is pulled to remove the filter screen 801 for replacement. After replacement, the connecting ring 809 is inserted back into the fixing ring 812, and the pull rod 816 is released. The second spring 813 moves the slider 814, which in turn moves the locking block 815, engaging it inside the connecting ring 809 to secure the filter screen 801, completing the replacement process.
[0022] Please see Figure 5 In this embodiment, the cover plate fixing assembly includes a first fixing plate 901. The first fixing plate 901 is provided on one side of the top cover 3, and a second fixing plate 902 is fixedly connected to one side of the descaling cylinder 1. A rotating block 903 is rotatably connected to the inner side of the second fixing plate 902. A threaded rod 904 is threadedly connected to the inner side of the rotating block 903. A limit block 905 is fixedly connected to the upper end of the threaded rod 904. A pull ring 906 is fixedly connected to one side of the limit block 905. A third sealing ring 907 is provided at the lower end of the top cover 3. A groove 3 is provided on the first fixing plate 901. The limit block 905 is movably connected to the first fixing plate 901 through the groove 3. The groove 3 on the first fixing plate 901 allows the limit block 905 to be movably connected to the first fixing plate 901, thereby limiting the position of the limit block 905.
[0023] During operation, cooling circulating water enters the inner side of filter screen 801 through inlet pipe 4. Filter screen 801 intercepts dirt in the cooling circulating water, which then enters descaling cylinder 1 and is finally discharged through outlet pipe 5. Starting drive motor 802 rotates rotating rod 803, which in turn rotates fixed frame 804. First spring 805 provides elastic support to sliding rod 806. Sliding rod 806, via connecting plate 807, drives cleaning brush 808 to abut against the inner wall of filter screen 801. Fixed frame 804 then drives sliding rod 806... Rotating the slide bar 806 via the connecting plate 807 drives the cleaning brush 808 to rotate, removing dirt from the inner wall of the filter screen 801. Then, the electric valve 7 is activated, and the dirt is discharged through the drain pipe 6. When the top cover 3 needs to be opened, rotating the pull ring 906 causes the limiting block 905 to rotate. The limiting block 905 causes the threaded rod 904 to rotate inside the rotating block 903, thereby causing the limiting block 905 to disengage from the groove on the first fixed plate 901, releasing the limiting fixation of the first fixed plate 901. Then, rotating the rotating block 903 causes the limiting block 905 to move away from above the first fixed plate 901. Pull the top cover 3 to open it. To fix the top cover 3, rotate the rotating block 903 to rotate the limiting block 905 above the first fixing plate 901. Then rotate the pull ring 906, which drives the limiting block 905 to rotate. The limiting block 905 drives the threaded rod 904 to rotate, and the threaded rod 904 drives the limiting block 905 to move, so that the limiting block 905 engages with the groove on the first fixing plate 901, thereby fixing the top cover 3. The descaling cylinder 1 is sealed by the third sealing ring 907. When replacing the filter screen 801, open the top cover 3 and then pull the pull rod 816. The slider 814 moves, pressing against the second spring 813. The slider 814 then moves the locking block 815, disengaging it from the connecting ring 809 and releasing its restraint. The connecting ring 809 is then pulled to remove the filter screen 801 for replacement. After replacement, the connecting ring 809 is inserted back into the fixing ring 812, and the pull rod 816 is released. The second spring 813 moves the slider 814, which in turn moves the locking block 815, engaging it within the connecting ring 809 to secure the filter screen 801, thus completing the replacement process.
[0024] Through the above steps, cooling circulating water enters the inner side of filter screen 801 through inlet pipe 4. Filter screen 801 intercepts the dirt in the cooling circulating water. The cooling circulating water then enters descaling cylinder 1 through filter screen 801 and is finally discharged through outlet pipe 5. By starting drive motor 802, drive motor 802 drives rotating rod 803 to rotate. Rotating rod 803 drives fixed frame 804 to rotate. First spring 805 provides elastic support for sliding rod 806. Sliding rod 806 drives cleaning brush 808 to abut against the inner wall of filter screen 801 through connecting plate 807. Fixed frame 804 drives sliding rod 806 to rotate. Sliding rod 806 drives cleaning brush 808 to rotate through connecting plate 807, thus brushing away dirt from the inner wall of filter screen 801. Then, the electric motor is started. Valve 7 allows dirt to be discharged through drain pipe 6. When replacing filter screen 801, open top cover 3 and pull rod 816. Rod 816 moves slider 814, which in turn presses against second spring 813. Slider 814 then moves locking block 815, disengaging it from connecting ring 809 and releasing the limiting effect on connecting ring 809. Then, pull connecting ring 809 to remove filter screen 801 for replacement. After replacement, insert connecting ring 809 into fixing ring 812, release rod 816, and second spring 813 moves slider 814, which in turn moves locking block 815, engaging it inside connecting ring 809 to secure filter screen 801 and complete the replacement.
