[0002] A composite flow cooling tower is a type of cooling equipment primarily used for cooling media, characterized by high efficiency, energy saving, and environmental friendliness. During operation, the composite flow cooling tower continuously sprays cooling water. Top and side air intakes cool the water, allowing for its recycling. However, during this recycling process, impurities inevitably accumulate. Directly circulating the cooling water can easily clog the sprayers, thus affecting cooling efficiency. Therefore, this application proposes a pretreatment device for the inlet water of a composite flow cooling tower. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1 to 5 This invention discloses a pretreatment device for the inlet water of a composite flow cooling tower, comprising a pretreatment device body 1 located on one side of a composite flow cooling tower 2. The pretreatment device body 1 consists of a pretreatment tank 3, an inlet pipe 4, a pumping pipe 5, a water pump 6, a water supply pipe 7, a filter plate 8, an anti-clogging scraping assembly 9, and a control panel 10. The inlet pipe 4 is connected between the pretreatment tank 3 and the composite flow cooling tower 2. The water pump 6 is located on one side of the pretreatment tank 3. The pumping pipe 5 is connected between the water pump 6 and the pretreatment tank 3. The water supply pipe 7 is connected between the water pump 6 and the composite flow cooling tower 2. The filter plate 8 is fixedly connected to the bottom end of one side inside the pretreatment tank 3. The anti-clogging scraping assembly 9 is connected to the bottom end of the side of the pretreatment tank 3 near the filter plate 8 and is located at the bottom of the filter plate 8. The control panel 10 is fixedly connected to the front of the pretreatment tank 3.

[0022] The cooling water sprayed by the composite flow cooling tower 2 falls to the bottom of the composite flow cooling tower 2, and then enters the pretreatment tank 3 through the water inlet pipe 4. The water is filtered by the filter plate 8. The filtered water is discharged back into the composite flow cooling tower 2 through the water pump 6 and the water supply pipe 7, thus forming a circulation. The filter plate 8 can filter out impurities in the water and prevent the sprayers inside the composite flow cooling tower 2 from becoming blocked.

[0023] A water supply pipe 11 is provided on one side of the top of the pretreatment tank 3, and a liquid level sensor 12 is fixedly installed on one side inside the pretreatment tank 3.

[0024] During the spray cooling process, a small amount of cooling water will turn into steam, resulting in water loss. At this time, water can be added through the water supply pipe 11, and the water level can be monitored in real time through the liquid level sensor 12.

[0025] The filter plate 8 is composed of a mesh filter plate 13 and a water-permeable filter cloth 14. The mesh filter plate 13 is fixedly connected to the inside of the pretreatment box 3, and the water-permeable filter cloth 14 is connected to the bottom surface of the mesh filter plate 13. Both the mesh filter plate 13 and the water-permeable filter cloth 14 are arc-shaped structures.

[0026] The combined structure of the mesh filter plate 13 and the water-permeable filter cloth 14 can improve the filtration effect. Both the mesh filter plate 13 and the water-permeable filter cloth 14 are arc-shaped structures, which can cooperate with the anti-clogging scraping component 9.

[0027] The anti-clogging scraping assembly 9 consists of a drive motor 15, a rotating shaft 16, a scraper 17 and a scraper 2 18. The drive motor 15 is fixedly connected to the front of the pretreatment box 3, the rotating shaft 16 is rotatably connected to the inside of the pretreatment box 3 and fixedly connected to the output shaft of the drive motor 15, and the scraper 17 and scraper 2 18 are symmetrically connected to the side of the rotating shaft 16.

[0028] When the anti-clogging scraping assembly 9 is working, the drive motor 15 drives the rotating shaft 16 to rotate, and the rotating shaft 16 drives the scraper 17 and scraper 2 18 to rotate. The scraper 17 and scraper 2 18 are in contact with the filter plate 8 to scrape off the impurities at the bottom of the filter plate 8.

[0029] An L-shaped drain pipe 19 is fixedly installed at the middle position of the bottom front of the pretreatment box 3. A servo motor 20 is fixedly installed at one end of the L-shaped drain pipe 19. A sealing cover 21 is installed at the bottom of the L-shaped drain pipe 19. The sealing cover 21 is threadedly connected to the L-shaped drain pipe 19. A spiral discharge paddle 22 is rotatably installed at the middle position of the bottom inside the pretreatment box 3, which passes through the L-shaped drain pipe 19 and is fixedly connected to the output shaft of the servo motor 20.

[0030] When there are many impurities inside the pretreatment box 3, open the sealing cover 21, and drive the spiral discharge paddle 22 to rotate through the servo motor 20, so that the impurities can be discharged through the spiral discharge paddle 22.
