Description

Technical Field

[0001] This utility model belongs to the technical field of filtration devices, and specifically relates to a cooling tower debris filtration device. Background Technology

[0002] Cooling towers are widely used in industrial production and air conditioning systems. Their main function is to absorb heat through the evaporation of water, thereby lowering the water's temperature. A typical cooling tower consists of components such as a water tank, fan, packing material, and water pump. During long-term operation, various impurities gradually accumulate inside the cooling tower. These impurities may affect the cooling tower's efficiency and even cause damage to the equipment.

[0003] To address this problem, various filtration devices have been introduced in existing technologies to remove impurities from cooling towers. For example, Chinese patent document CN220418218U discloses a cooling tower debris filtration device. This device mainly includes components such as a water collection tray, a support frame, a housing, a first motor, a drive shaft, a fan, and inlet and outlet water pipes. Its working principle is to use the centripetal force generated by the vortex to gather impurities to the center of the vortex, and then, driven by the vortex, move the impurities downwards, ultimately storing them at the bottom of the inner wall of the baffle tube. Because a check plate is installed on the inner wall of the baffle tube, the impurities cannot move upwards, thus achieving the removal of impurities from the water.

[0004] However, while the devices described in the aforementioned patent documents can filter impurities in water to some extent, they have a significant drawback in practical use: they cannot effectively scrape off impurities inside the filter. This can lead to impurities accumulating inside the filter, affecting subsequent filtration efficiency and potentially causing other problems with the equipment.

[0005] Therefore, in order to improve the performance and efficiency of the cooling tower debris filtration device, it is necessary to improve the existing technology to achieve timely removal of impurities inside the filtration device, thereby ensuring the continuous and efficient operation of the cooling tower. Summary of the Invention

[0006] To solve the above technical problems, this utility model proposes a cooling tower debris filtration device. Through the set scraping component, impurities accumulated on the surface of the water inlet pipe can be scraped off, thereby preventing impurities from accumulating more and more on the surface of the water inlet pipe and affecting the filtration effect of the filter element. At the same time, the scraping component does not require an external power source and can be driven by the water flow inside the cooling tower, thereby reducing the operating cost.

[0041] To enable those skilled in the art to better understand this utility model, the present utility model will now be further described in conjunction with specific embodiments.

[0042] Example 1:

[0043] like Figures 1-5 As shown, this utility model provides a cooling tower debris filtration device, comprising:

[0044] Water inlet pipe 1;

[0045] Scraping component 2 is used to scrape off impurities accumulated on the inner surface of the water inlet pipe 1. The front part of the inner surface of the water inlet pipe 1 is connected to the scraping component 2.

[0046] Replace component 4 and fix component 4 to the upper part of the outer surface of the water inlet pipe 1.

[0047] Storage component 5 is fixedly installed on the lower part of the outer surface of the water inlet pipe 1;

[0048] Among them, the upper part of the inner surface of the water inlet pipe 1 and the lower part of the inner surface are provided with sliding grooves 3, the middle part of the water inlet pipe 1 is slidably connected with filter element 6, and the inner cavity of the sliding groove 3 located on the lower side is equipped with a blocking mechanism.

[0049] It should be noted that the water inlet pipe 1 mentioned above is part of the hot water output pipe of the cooling tower in the prior art. In the implementation process, it is only necessary to install it on the hot water output pipe so that hot water can flow through the water inlet pipe 1.

[0050] It should be noted that the blocking mechanism installed in the inner cavity of the sliding groove 3 is an existing design. Its structure can be an arc-shaped single plate or a metal spring sheet as in the prior art. It only needs to support the filter element 6 that is slidably connected in the inner cavity of the sliding groove 3, so that the filter element 6 can slide downward freely.

[0051] like Figures 1-4 As shown, the scraping component 2 includes:

[0052] A fixing plate 21 is fixedly connected to both the left and right sides of the inner surface of the water inlet pipe 1;

[0053] Rotating rod 22 is rotatably connected to the front end of fixed plate 21, and a rotating ring 23 is fixedly connected to the middle of the outer surface of rotating rod 22.

[0054] A number of L-shaped scrapers 24 arranged in a circular array, the outer surface of the rotating ring 23 is connected to the L-shaped scrapers 24, and one side of the L-shaped scrapers 24 is in contact with the inner surface of the water inlet pipe 1;

[0055] The trapezoidal column 25 is fixedly connected to the front of the outer surface of the rotating rod 22, and several arc-shaped plates 26 are fixedly connected to the outer surface of the trapezoidal column 25 in a ring array.

[0056] In use, when water flows through the inlet pipe 1, the water flows over the surface of the trapezoidal column 25 and several arc-shaped plates 26. The water flow can exert a force on the surface of the arc-shaped plates 26, causing the arc-shaped plates 26 to rotate under the force of the water flow. When the trapezoidal column 25 rotates, it can drive the rotating rod 22 to rotate at the middle of the front end of the fixed plate 21. Then the rotating rod 22 simultaneously drives the rotating ring 23 to rotate. As mentioned above, the L-shaped scraper 24 is in contact with the inner surface of the inlet pipe 1. Therefore, the L-shaped scraper 24 can scrape off the impurities adhering to the inner surface of the inlet pipe 1. Then the impurities in the water will be filtered through the filter element 6 and then continue to be transmitted from the rear side of the inlet pipe 1 to the subsequent connecting parts.

[0057] The scraping component 2 can scrape away impurities on the inner surface of the water inlet pipe 1, thereby preventing impurities from accumulating on the inner surface of the water inlet pipe 1 for a long time, which would affect the filtration effect of the filter element 6.

[0058] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the replacement component 4 includes:

[0059] The outer casing 41 is fixedly connected to the upper part of the outer surface of the water inlet pipe 1. The lower part of the left side wall and the lower part of the right side wall of the inner surface of the outer casing 41 are both provided with placement grooves 42. The upper part of the inner surface of the two placement grooves 42 is rotatably connected to the support plate 43. The ends of the placement grooves 42 and the support plate 43 on the same side that are close to each other are fixedly connected to springs 44. The upper side of the two support plates 43 is provided with filter element 45.

[0060] T-shaped pressing plate 46 is slidably connected to the upper part of the inner surface of the outer casing 41.

[0061] Furthermore, the size of the support plate 43 is smaller than the size of the placement slot 42.

[0062] Furthermore, the width of the support plate 43 is smaller than the width of the sliding groove 3.

[0063] Furthermore, the storage component 5 includes a storage box 51 fixedly connected to the lower part of the outer surface of the water inlet pipe 1, a baffle 52 rotatably connected to the lower part of the storage box 51, and a pull block 53 fixedly connected to the lower left part of the baffle 52.

[0064] Furthermore, a damping shaft is installed at the connection between the baffle 52 and the storage box 51.

[0065] In use, a damping shaft is installed at the connection between the baffle 52 and the storage box 51. The damping shaft is a conventional design in the prior art. The damping shaft usually contains friction material. When it rotates, the friction will consume some mechanical energy, thereby reducing the transmission of vibration and impact force. This makes the baffle 52 have sufficient resistance when rotating on the surface of the damping shaft, thereby preventing the baffle 52 from rotating randomly on the lower part of the inner surface of the storage box 51.

[0066] It should be noted that the outer surfaces of filter element 45 and filter element 6 mentioned above are fitted with edges to facilitate subsequent disassembly and installation.

[0067] Working principle: When in use, by pressing down quickly on the T-shaped pressing plate 46, the T-shaped pressing plate 46 quickly squeezes the filter element 45, which in turn causes the filter element 45 to move downward quickly in the inner cavity of the outer shell 41. Then the filter element 45 squeezes the support plates 43 on both sides, and then the support plates 43 on both sides squeeze the spring 44 on the same side. After that, the support plates 43 on both sides are stored in the placement groove 42 on the same side.

[0068] Then, filter element 1 45 will contact filter element 2 6 through the upper sliding groove 3 and squeeze filter element 2 6. Then filter element 2 6 will slide into the storage box 51 from the lower sliding groove 3. Then filter element 1 45 will slide into the middle of the inner surface of the water inlet pipe 1 from the upper sliding groove 3 and completely fit with the water inlet pipe 1. At the same time, the placement grooves 42 on both sides will no longer be squeezed, so that the placement grooves 42 on both sides will drive the corresponding support plate 43 to spring back to the initial state.

[0069] Then, when it is necessary to take out the filter element 6 from the storage box 51, simply pull the pull block 53 to open the baffle 52, then take out the filter element 6 and close the baffle 52.

[0070] After the filter element 45 inside the housing 41 is inserted into the inner cavity of the water pipe 1, the T-shaped pressing plate 46 can be removed. Then, the brand new filter element 45 can be placed into the inner cavity of the storage box 51 for storage, so that it can be replaced next time.

[0071] The replacement component 4 and storage component 5 facilitate the replacement of filter element 6, thereby improving the service life and filtration effect of the device.

[0072] The above are merely preferred embodiments of the present utility model and do not limit the patent scope of the present utility model. All equivalent changes and modifications made within the scope of the present utility model shall still fall within the scope of the present utility model.
