Description

Technical Field

[0001] This utility model relates to the field of iron filings adsorption technology, and in particular to an iron filings adsorption device for cooling towers. Background Technology

[0002] In industrial production processes, cooling towers are widely used in various scenarios requiring reduced circulating water temperature. Crossflow cooling towers, due to their unique structural design and efficient cooling performance, are widely used in numerous fields. The cooling principle of a crossflow cooling tower is mainly achieved through heat exchange between water and air. Water inlet pipes are installed around the top of the cooling tower, and water distributors are installed at the bottom of these pipes. The water inlet pipes deliver water to the water distributors inside the cooling tower, and then the water distributors distribute the water evenly in the packing material inside the cooling tower. The packing material plays a crucial role in the cooling process. It changes the flow path of water and air, so that the water does not fall directly and quickly in the packing material, but flows in a tortuous manner along the surface of the packing material. At the same time, the air also needs to meander through the gaps in the packing material due to the obstruction and guidance of the packing material. In this process, water and air come into full contact and exchange heat, thereby achieving the purpose of cooling the water.

[0003] Since the inlet pipe is mostly made of iron, it is prone to oxidation during long-term use, which causes the inner wall of the pipe to rust. Over time, the rust layer gradually thickens and eventually forms iron filings. When the cooling water is discharged from the inlet pipe and flows into the water distributor, these iron filings will be carried into the water distributor with the water flow and further evenly distributed on the packing of the cooling tower. The presence of iron filings will not only interfere with the normal operation of the packing and reduce the heat exchange efficiency, but may also cause the packing to become blocked, affecting the cooling effect of the cooling tower.

[0004] Existing water inlet pipes typically have filters installed inside. The main function of the filters is to intercept impurities such as iron filings, preventing them from entering the water distributor and packing. However, over long-term use, the filters gradually become clogged due to the continuous interception of iron filings and other impurities. Once clogged, the water flow capacity decreases, leading to a significant reduction in the flow rate of the water inlet pipe. This not only affects the normal delivery of cooling water and reduces the cooling efficiency of the cooling tower, but may also cause localized overheating of the cooling system, adversely affecting the entire industrial production process.

[0005] To address the aforementioned problems, this application proposes a cooling tower iron filings adsorption device. Utility Model Content

[0006] Based on the technical problems existing in the background art, this utility model proposes a cooling tower iron filings adsorption device.

[0007] This utility model proposes a cooling tower iron filings adsorption device, which includes a sleeve shaft;

[0008] The inner wall of the sleeve is equipped with a plurality of circumferentially arranged loading components, and magnetic rods can be detachably installed at the bottom of each of the plurality of loading components.

[0009] A magnetic ring is installed at the bottom of the sleeve shaft. A scraper is magnetically connected to the bottom of the magnetic ring and is sleeved on multiple magnetic rods. When the scraper is separated from the magnetic ring, it is used to scrape off iron filings adsorbed on the magnetic rods.

[0010] Preferably, the loading component includes a loading shaft and fixing blocks. Multiple circumferentially arranged fixing blocks are installed on the inner wall of the shaft, and loading shafts are installed on each of the fixing blocks. Multiple magnetic rods are detachably installed at the bottom of the multiple loading shafts.

[0011] Preferably, the magnetic rod component includes a magnetic rod body and a screw head, the bottom of the loading shaft is provided with a threaded groove, multiple screw heads are respectively threaded into the threaded grooves at the bottom of multiple loading shafts, and multiple magnetic rod bodies are respectively installed at the bottom of multiple screw heads.

[0012] Preferably, the scraping component includes a loading ring, magnet blocks, and scraping parts. The loading ring is disposed below the magnetic ring body. Multiple circumferentially distributed magnet blocks are installed on the loading ring and are magnetically connected to the magnetic ring body. Multiple circumferentially arranged scraping parts are installed on the inner wall of the loading ring, and the multiple scraping parts are respectively sleeved on multiple magnetic rods.

[0013] Preferably, the scraping part includes a fixing rod and a scraping collar. The inner wall of the loading ring is equipped with a plurality of circumferentially arranged fixing rods, and a scraping collar is installed at one end of each fixing rod. The plurality of scraping collars are slidably sleeved on the plurality of magnetic rods.

[0014] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0015] 1. When in use, the sleeve thread is fitted onto the bottom of the cooling tower inlet pipe. When the inlet pipe delivers cooling water to the water distributor inside the cooling tower, it passes through multiple magnetic rods arranged in a ring at the bottom of the sleeve. The magnetic rods in the magnetic rods magnetically attract iron filings carried in the water flow, preventing them from entering the water distributor and packing. This fundamentally solves the problems of iron filings interfering with the normal operation of the packing, reducing heat exchange efficiency, and causing packing blockage, thereby ensuring that the cooling effect of the cooling tower is not affected and maintaining the stable operation of the cooling system.

[0016] 2. When it is necessary to clean the iron filings on the magnetic rods, the sleeve can be unscrewed from the water inlet pipe, and then downward pressure can be applied to the scraper under the sleeve to separate the scraper from the magnetic ring at the bottom of the sleeve. This allows the scraping part on the scraper, which is fitted onto multiple magnetic rods, to slide down and scrape off the iron filings from multiple magnetic rods at once, thus achieving the cleaning effect. Afterwards, the sleeve can be reinstalled at the bottom of the sleeve. This design makes the cleaning operation simple and quick, without the need for complicated tools and cumbersome steps, saving the time and labor costs required for cleaning. Compared with the traditional filter cleaning method, it eliminates the need for frequent filter replacement, reducing filter wear and replacement costs. It also avoids the risks of reduced cooling water flow, reduced cooling tower cooling efficiency, and local overheating of the cooling system caused by filter clogging, thus improving the overall operating efficiency and economy of the cooling system.

[0017] 3. Because the magnetic rod is detachably connected to the loading component on the inner wall of the sleeve, when only a single magnetic rod has iron filings adsorbed, it can be unscrewed from the bottom of the loading component to clean that single rod without having to disassemble the entire adsorption device. This flexible disassembly method makes the cleaning work more targeted, allowing for the cleaning of only the magnetic rods that need cleaning based on the specific situation of iron filings adsorption, further improving cleaning efficiency and reducing unnecessary cleaning workload. At the same time, this design also facilitates the individual inspection and maintenance of the magnetic rod, ensuring that the adsorption performance of the magnetic rod is always kept in good condition, thereby better fulfilling its function of intercepting iron filings.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0025] like Figure 1-5 As shown, the present invention proposes a cooling tower iron filings adsorption device, which includes a sleeve shaft 1;

[0026] Multiple circumferentially arranged loading parts 2 are installed on the inner wall of the sleeve shaft 1, and magnetic rod parts 3 can be detachably installed on the bottom of each loading part 2;

[0027] A magnetic ring 101 is installed at the bottom of the sleeve shaft 1. A scraper 4 is magnetically connected to the bottom of the magnetic ring 101 and is sleeved on multiple magnetic rods 3. When the scraper 4 is separated from the magnetic ring 101, it is used to scrape off the iron filings adsorbed on the magnetic rods 3.

[0028] The sleeve 1 is threaded onto the bottom of the water inlet pipe of the cooling tower, allowing the cooling water to flow smoothly through the inside of the device. When the water flows down the sleeve 1 through the water inlet pipe, it passes through the magnetic rod 3. The magnetic rod 3 uses its own magnetism to firmly attract iron filings in the water to its surface as the cooling water passes through, preventing the iron filings from entering the water distributor and packing with the water flow. This avoids the impact of iron filings on the heat exchange efficiency of the cooling tower and the problem of packing blockage from the source. When it is necessary to clean the iron filings on the magnetic rod 3, the sleeve 1 can be unscrewed from the bottom of the water inlet pipe, and then a downward force is applied to the scraper 4. The external force causes the scraper 4 to separate from the magnetic ring 101. The scraper 4 slides down along the magnetic rod 3, which can scrape off the iron filings on the surface of multiple magnetic rods 3 at once. The cleaning process does not require disassembling a large number of parts, making the operation convenient and efficient, effectively reducing cleaning time and labor costs, and avoiding the problem of excessive downtime of the cooling system caused by disassembly during traditional filter cleaning.

[0029] In a specific embodiment, the loading component 2 includes a loading shaft 21 and fixing blocks 22. Multiple circumferentially arranged fixing blocks 22 are installed on the inner wall of the sleeve shaft 1, and loading shafts 21 are installed on each of the fixing blocks 22. Multiple magnetic rods 3 are detachably installed at the bottom of the multiple loading shafts 21. The circumferential arrangement of the multiple fixing blocks 22 ensures that the multiple loading shafts 21 are evenly distributed inside the sleeve shaft 1, thereby forming an annular adsorption area for the subsequently installed magnetic rods 3. This ensures that when cooling water flows through the sleeve shaft 1, iron filings in the water can be adsorbed in all directions, avoiding adsorption dead zones. 1. Vertically mounted on the fixed block 22, its main function is to provide a mounting carrier for the magnetic rod 3. Through the detachable connection with the magnetic rod 3, the magnetic rod 3 can be disassembled individually. When a certain magnetic rod 3 has a lot of iron filings adsorbed or has weakened magnetism, it is not necessary to remove the entire adsorption device from the water inlet pipe. It is only necessary to remove the magnetic rod 3 from the corresponding loading shaft 21 for cleaning or replacement. This improves the flexibility and efficiency of maintenance, reduces the overall maintenance cost of the device, and reduces the downtime of the cooling system caused by maintenance, ensuring the continuous and stable operation of the cooling tower.

[0030] In a specific embodiment, the magnetic rod component 3 includes a magnetic rod body 31 and screw heads 32. A threaded groove is provided at the bottom of the loading shaft 21, and multiple screw heads 32 are respectively threaded into the threaded grooves at the bottom of the multiple loading shafts 21. Multiple magnetic rod bodies 31 are respectively installed at the bottom of the multiple screw heads 32. The magnetic rod body 31 is a key component for generating magnetic attraction. It is made of highly magnetic material and can form a strong magnetic field region around itself. When cooling water carrying iron filings flows past the magnetic rod body 31, the iron filings are attracted to the surface of the magnetic rod body 31 under the action of the magnetic field, thus achieving the separation of the iron filings from the cooling water. This effectively prevents iron filings from entering the water distributor and packing, avoiding packing blockage and reduced heat exchange efficiency, thus ensuring the cooling effect of the cooling tower. When disassembling the magnetic rod 3, the operator only needs to rotate the magnetic rod 31 to unscrew the screw head 32 from the bottom of the loading shaft 21. When it is necessary to clean the iron filings on the surface of the magnetic rod 31 or check the magnetic state of the magnetic rod 31, the magnetic rod 31 can be quickly removed, cleaned or maintained, and then reinstalled, improving the convenience of maintenance. At the same time, it ensures that each magnetic rod 31 can always maintain good adsorption performance, ensuring the overall iron filings adsorption effect of the device.

[0031] In a specific embodiment, the scraping component 4 includes a loading ring 41, a magnet block 42, and a scraping part 43. The loading ring 41 is disposed below the magnetic ring body 101. Multiple circumferentially distributed magnet blocks 42 are installed on the loading ring 41 and are magnetically connected to the magnetic ring body 101. Multiple circumferentially arranged scraping parts 43 are installed on the inner wall of the loading ring 41, and the multiple scraping parts 43 are respectively sleeved on multiple magnetic rods 31. The scraping part 43 includes a fixing rod 431 and a scraping collar 432. Multiple circumferentially arranged fixing rods 431 are installed on the inner wall of the loading ring 41, and a scraping collar 432 is installed at one end of each of the multiple fixing rods 431. The multiple scraping collars 432 are respectively slidably sleeved on the multiple magnetic rods 31.

[0032] When it is necessary to clean the iron filings on the magnetic rod 31, the sleeve 1 can be unscrewed from the bottom of the water inlet pipe on the cooling tower. This can apply downward pressure to the loading ring 41, causing the magnet 42 to separate from the magnetic ring 101. During the cleaning operation, the loading ring 41 drives the fixing rod 431 and the scraping sleeve 432 to slide down along the magnetic rod 31. The inner wall of the scraping sleeve 432 slides relative to the surface of the magnetic rod 31, thoroughly scraping away the iron filings adsorbed on the surface of the magnetic rod 31, thus achieving the cleaning effect. After cleaning, the sleeve 1 can be reinstalled at the bottom of the water inlet pipe.

[0033] The specific working principle of this device is as follows:

[0034] First, the sleeve 1 is threaded onto the bottom of the cooling tower inlet pipe to complete the connection between the device and the cooling system. When the cooling tower inlet pipe delivers cooling water, the water flows through the inside of the sleeve 1 and falls. The magnetic rod 31 uses its own magnetism to attract the iron filings carried in the water flow to its surface, preventing the iron filings from entering the subsequent water distributor and packing with the water flow. This fundamentally avoids the interference of iron filings on the normal operation of the packing, the reduction of heat exchange efficiency, and the problem of packing blockage, thus ensuring the stable cooling effect of the cooling tower.

[0035] When a lot of iron filings are adsorbed on the surface of the magnetic rod 31 and need to be cleaned, first unscrew the sleeve 1 from the water inlet pipe, then apply a downward force to the loading ring 41 to separate the magnet 42 from the magnetic ring 101. The loading ring 41 drives the fixing rod 431 and the scraping sleeve 432 to slide down along the magnetic rod 31. Since the inner diameter of the scraping sleeve 432 is adapted to and tightly fitted with the outer diameter of the magnetic rod 31, the inner wall of the scraping sleeve 432 slides relative to the surface of the magnetic rod 31 during the sliding process, and the iron filings on the surface of the magnetic rod 31 are completely scraped off. Multiple scraping sleeves 432 move synchronously to clean the iron filings of multiple magnetic rods 31 at one time. If only a single magnetic rod 31 has a lot of iron filings adsorbed, there is no need to disassemble the sleeve 1. Just rotate the magnetic rod 31 to separate the screw head 32 from the thread groove of the loading shaft 21, remove the magnetic rod 31 separately for cleaning, and reinstall it back onto the loading shaft 21 through the screw head 32 after cleaning.

[0036] After the iron filings are cleaned, if the sleeve shaft 1 is disassembled, the scraper 4 is pushed upwards to reconnect the magnet 42 with the magnetic ring 101, thus resetting the scraper 4. Then, the sleeve shaft 1 is re-threaded back onto the bottom of the water inlet pipe, and the device returns to the iron filings adsorption working state. If only the magnetic rod 3 is disassembled, the cleaned magnetic rod 3 is reinstalled back onto the loading shaft 21, and the device directly restores the iron filings adsorption function, continuing to intercept iron filings for the cooling tower cooling system and ensuring the continuous and stable operation of the cooling system.

[0037] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model, and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
