Description

Technical Field

[0001] This invention belongs to the technical field of cooling tower equipment, specifically a mechanical ventilation cooling tower. Background Technology

[0002] Mechanical ventilation cooling towers are cooling towers that rely on airflow for ventilation. They are divided into crossflow cooling towers and counterflow cooling towers. They mainly consist of a fan, tower packing, water collector, louvers, etc. When working, mechanical ventilation cooling towers use the fan to generate flowing air, which accelerates the heat exchange between water and air. Through evaporative heat dissipation, convective heat transfer, and radiative heat transfer, the circulating working water is cooled down, achieving the purpose of cooling.

[0003] During the operation of a cooling tower, the packing material is a crucial component. Its efficiency depends on the degree of contact between the cooling water and air within the packing material. However, in the long-term use of open cooling towers, due to their constant exposure to the elements and the strong suction of the fans, a large amount of mud, sand, and dirt enters the tower and eventually settles on the packing layer, resulting in excessive deposits. Simultaneously, scale generated during water flow also deposits on the packing material. These deposits prevent water from forming a film on the packing surface, thus reducing the contact efficiency between water and airflow and weakening the cooling effect of the cooling tower. Therefore, regular cleaning and replacement of the packing material are necessary during the routine maintenance of cooling towers.

[0004] In related technologies, since the packing material is mostly fixed inside the cooling tower by fixing devices, when cleaning or replacing the packing material, it is necessary to open the fixing devices, remove the packing material one by one, and then concentrate it outside the tower for rinsing. After cleaning, the packing material is refilled into the cooling tower to complete the cleaning of the packing material. However, in actual operation, it was found that due to the large number of packing materials, removing, cleaning, and refilling all the packing material in a single cleaning process is not only time-consuming and requires the cooling tower to be shut down for a long time, but also requires a large amount of work for the staff to move the packing material, which is not convenient for the convenient handling of the packing material cleaning.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the present invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0008] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a mechanical ventilation cooling tower, which includes a tower body, the tower body is a cavity structure, the top of the tower body is open, the middle of the tower body is provided with a ventilation slot, a fan is installed at the opening of the tower body by means of a bracket, and the inside of the tower body is filled with filler.

[0009] The mounting plate is installed inside the tower body cavity and is used to support the packing material.

[0010] The water inlet and outlet assembly and the water distributor are fixedly installed at the bottom of the tower body and installed inside the tower body. The water inlet and outlet assembly is electrically connected to the inner cavity of the tower body and the water distributor. The water inlet and outlet assembly is externally connected to a circulating water pipe.

[0011] It also includes a convenient filling assembly for rapid loading of filler;

[0012] The convenient filling component includes a sliding rail with a circular design. The sliding rail is fixedly installed on the inner wall of the tower body, and the mounting plate is rotatably connected to the sliding rail.

[0013] The mounting frame is a frame structure with an open top. Multiple mounting frames are arranged in a circle on the mounting plate, and the filler is filled inside the mounting frame.

[0014] The mounting plate has evenly distributed push-pull grooves, and the mounting frame is slidably connected to the mounting plate through the push-pull grooves.

[0015] The tower body has a docking groove and an opening and closing door. The tower body has a docking groove on its outer wall and an opening and closing door is rotatably installed on the docking groove. The mounting frame moves to the outside of the tower body through the docking groove.

[0016] An auxiliary flushing assembly is installed on the tower body and works in conjunction with a convenient filling assembly to reduce the difficulty of flushing the packing material.

[0017] Specifically, the convenient filling component also includes a translation rail, and a translation rail is installed on the outside of the tower body, with the translation rail corresponding to the push-pull groove;

[0018] Support legs: The translation rail is equipped with symmetrically designed support legs on the side away from the tower body.

[0019] Specifically, a deflection groove is provided at the bottom of the docking groove, the translation rail is rotatably connected in the deflection groove, a connecting piece is hinged on the translation rail, and the support leg is symmetrically hinged to the connecting piece.

[0020] Specifically, each of the support legs has a roller rotatably connected to the end away from the translation rail, and each support leg has a rotating groove. A connecting block is rotatably connected in one of the rotating grooves, and a lead screw is rotatably connected to the connecting block. A nut is rotatably connected in the other rotating groove, and the lead screw and nut are driven by a helical transmission.

[0021] Specifically, the auxiliary flushing assembly includes an auxiliary plate, which is hinged to a translation rail;

[0022] The guide rod has a storage groove on one side of the auxiliary plate, a rotating block is hinged in the storage groove, a guide rod is rotatably mounted on the rotating block, and a reciprocating thread is provided on the guide rod.

[0023] A paddle is mounted on the guide rod, and the paddle is helically connected to the guide rod.

[0027] Specifically, the auxiliary plate has an extension groove on the side away from the storage groove, and the extension groove is connected to the translation rail.

[0028] The beneficial effects of this invention are as follows:

[0029] 1. The mechanical ventilation cooling tower of the present invention, by setting a sliding rail and an installation frame, fills the packing material in groups in the installation frame and slides the installation frame on the installation plate. Therefore, when installing or removing the packing material, it is only necessary to open the opening door on the side wall of the tower body and push or pull the installation frame directly to move the packing material loaded in the installation frame externally or install it inward. Through the rotational connection between the installation plate and the sliding rail, multiple sets of installation frames can be aligned with the docking slot in sequence, thereby effectively enhancing the convenience of cleaning and maintaining the packing material and reducing the workload of the staff.

[0030] 2. The mechanical ventilation cooling tower of the present invention allows for manual untying or loosening of knots, increasing the movable distance between the two end caps. This causes the packing material within the frame to move towards the end caps, reducing the packing material's fit and increasing the gaps between the packing materials. Combined with the scraping action of the scraper against the packing material, the gaps between the scraped packing material and adjacent packing materials are further increased. This facilitates the removal of scale, impurities, and other debris through the gaps in the packing material, further enhancing the cleaning effect. Simultaneously, as the movable distance of the packing material increases, the deformation and vibration of the packing material during scraping by the scraper also increase, further enhancing the cleaning effect.

[0041] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0042] like Figures 1 to 8 As shown, the mechanical ventilation cooling tower of the present invention includes a tower body 1, which is a cavity structure. The top of the tower body 1 is open, and a ventilation slot 11 is provided in the middle of the tower body 1. A fan 12 is installed at the opening of the tower body 1 by means of a bracket. The interior of the tower body 1 is filled with filler.

[0043] Mounting plate 2 is installed in the inner cavity of tower body 1 and is used to support packing material;

[0044] The water inlet and outlet assembly 13 and the water distributor 14 are provided. The water inlet and outlet assembly 13 is fixedly installed at the bottom of the tower body 1, and the water distributor 14 is installed inside the tower body 1. The water inlet and outlet assembly 13 is electrically connected to the inner cavity of the tower body 1 and the water distributor 14. The water inlet and outlet assembly 13 is externally connected to a circulating water pipe.

[0045] It also includes a convenient filling assembly for rapid loading of filler;

[0046] The convenient filling component includes a sliding rail 21, which has a circular design. The sliding rail 21 is fixedly installed on the inner wall of the tower body 1, and the mounting plate 2 is rotatably connected to the sliding rail 21.

[0047] Mounting frame 22, the mounting frame 22 is a frame structure, the top of the mounting frame 22 is designed to be open, the mounting frame 22 is designed in multiples, and the mounting frames 22 are arranged in a circle on the mounting plate 2, and the filler is filled inside the mounting frame 22;

[0048] Push-pull groove 23: The mounting plate 2 is provided with evenly distributed push-pull grooves 23, and the mounting frame 22 is slidably connected to the mounting plate 2 through the push-pull grooves 23;

[0049] The tower body 1 has a docking groove 24 and an opening and closing door 25. The docking groove 24 is provided on the outer wall of the tower body 1. The opening and closing door 25 is rotatably installed on the docking groove 24. The mounting frame 22 moves to the outside of the tower body 1 through the docking groove 24.

[0050] An auxiliary flushing assembly is installed on the tower body 1. The auxiliary flushing assembly works in conjunction with the convenient filling assembly. The auxiliary flushing assembly reduces the difficulty of flushing the packing material.

[0051] During the long-term use of the cooling tower, the external circulating water pipes deliver cooling water for the machinery to the water distributor 14 through the inlet / outlet water assembly 13. The water distributor 14 is preferably a spray pipe. The cooling water is sprayed out through the water distributor 14 and, under the action of gravity, falls onto the surface of the packing material, forming a water film on the surface and in the gaps of the packing. Simultaneously, the fan 12 continuously rotates, drawing air and water vapor from inside the tower body 1 and conveying them to the outside, creating a negative pressure inside the tower body 1. Under this negative pressure, outside air moves into the tower body 1 through the ventilation slot 11 in the middle of the tower body 1, and then moves towards the opening at the top of the tower body 1, causing the water flow and air flow to flow in opposite directions. When the cooling water and air... When the packing material meets the cooling water, heat is transferred from the cooling water through heat exchange between the air and the cooling water, as well as the evaporation of the cooling water, thereby cooling the cooling water. After the cooling tower has been running for a long time, under the action of airflow extraction, external dust, impurities, and scale in the cooling water will all be deposited on the packing material. At this time, the packing material needs to be cleaned regularly to prevent scale and impurities from clogging and damaging the packing material, thereby preventing a decrease in the film-forming performance of the cooling water on the packing material. When the packing material has been used for a long time, the accumulation of scale and impurities inside it is quite serious. At this time, the packing material needs to be completely disassembled and cleaned. In this application, the packing material is made of sheet or block material, which is inserted vertically into the installation frame 22, causing the packing material to... The two ends of the packing are flush with the upper and lower sides of the mounting frame 22, respectively. When cleaning and maintaining the packing, the staff first opens the opening door 25. Since the opening door 25 is hinged in the docking groove 24, when the opening door 25 is opened, the inner cavity of the tower body 1 is connected to the outside under the action of the docking groove 24. At this time, the staff manually pulls the mounting frame 22, causing the mounting frame 22 to slide on the mounting plate 2. Since the mounting frame 22 and the mounting plate 2 are connected by the sliding and limiting connection through the push-pull groove 23, and the push-pull groove 23 is arranged according to the diameter direction of the mounting plate 2, when the mounting frame 22 is pulled, the mounting frame 22 carries the packing and moves into the docking groove 24, and is finally disassembled outside the tower body 1. Then, the staff manually pushes the mounting plate 2, causing the mounting plate 2 to... Rotating the sliding rail 21 allows the multiple mounting frames 22 installed on the mounting plate 2 to be connected to the docking slot 24 in sequence, thereby reducing the difficulty of disassembling the packing. During routine maintenance, when the packing is less contaminated by scale or other pollutants, the staff only needs to manually pull the mounting frame 22, causing part of the mounting frame 22 to move to the outside of the tower body 1. At this time, the staff can use tools to flush and scrape the surface and bottom layers of the packing fixed inside the mounting frame 22 to remove impurities. Then, the packing can be pushed back into the tower body 1. Rotating the mounting plate 2 allows the packing in the multiple mounting frames 22 to be cleaned in sequence, thus completing the routine maintenance of the packing and enhancing the convenience of packing maintenance.

[0052] This invention, by setting up a sliding rail 21 and an installation frame 22, allows the packing material to be grouped and filled into the installation frame 22, and the installation frame 22 to be slidably installed on the installation plate 2. Therefore, when installing or removing the packing material, it is only necessary to open the opening door 25 on the side wall of the tower body 1 and push or pull the installation frame 22 directly to move the packing material loaded in the installation frame 22 externally or install it inward. Through the rotational connection between the installation plate 2 and the sliding rail 21, multiple sets of installation frames 22 can be aligned with the docking groove 24 in sequence, thereby effectively enhancing the convenience of cleaning and maintaining the packing material and reducing the workload of the staff.

[0053] In a preferred embodiment of the present invention, the convenient filling component further includes a translation rail 26, which is installed on the outer side of the tower body 1, and the translation rail 26 is correspondingly arranged with the push-pull groove 23;

[0054] Support legs 3, the translation rail 26 is equipped with symmetrically designed support legs 3 on the side away from the tower body 1;

[0055] By setting up the translation rail 26 and support legs 3, when the packing only needs cleaning and simple replacement during long-term use, the operator manually opens the opening door 25, causing the docking slot 24 to open. Then, the operator manually pulls the installation frame 22, causing it to slide within the sliding groove 23 and gradually pull it into the translation rail 26. Using the translation rail 26 and support legs 3, the installation frame 22 is supported, thus securing it outside the tower body 1. Subsequently, the operator manually uses flushing water pipes, brushes, and other tools to flush the packing inside the installation frame 22. The packing is flushed to remove impurities, sand, and other debris accumulated on its surface. Alternatively, damaged or replacement packing can be manually removed from the mounting frame 22 and replaced with new packing. This simple maintenance process allows for easy cleaning of the packing. After maintenance, the mounting frame 22 is manually pushed onto the mounting plate 2, and the mounting plate 2 is manually rotated to clean the packing in each mounting frame 22. Compared to existing technologies where the packing is wrapped and fixed inside the tower body 1, requiring disassembly of each packing for cleaning, this application significantly enhances the convenience of packing cleaning.

[0056] In a preferred embodiment of the present invention, the bottom of the docking groove 24 is provided with a deflection groove 31, the translation rail 26 is rotatably connected in the deflection groove 31, a connecting piece 32 is hinged on the translation rail 26, and the support leg 3 is symmetrically hinged to the connecting piece 32.

[0057] By opening the deflection groove 31, during the initial installation of the cooling tower, the translation rail 26 is hinged in the deflection groove 31 using a guide rod, allowing the translation rail 26 to rotate relative to the tower body 1. The connecting piece 32 is first hinged to one end of the translation rail 26, and then the support leg 3 is symmetrically hinged to the connecting piece 32. The hinge directions of the connecting piece 32, the translation rail 26, and the support leg 3 are different. Therefore, when not in use, the staff manually closes the two support legs 3 together, and then rotates the support leg 3 and the connecting piece 32 as a whole towards the translation rail 26, causing the support leg 3, the connecting piece 32, and the translation rail 26 to fit together. Then, the translation rail 26 is rotated, causing the translation rail 26 to fit against the tower body 1. This effectively folds and stores the support leg 3 and the translation rail 26, reducing the space they occupy and also reducing the chance of damage during daily storage.

[0058] In a preferred embodiment of the present invention, each of the support legs 3 is rotatably connected to a roller 4 at the end away from the translation rail 26, and each of the support legs 3 is provided with a rotating groove 41. A connecting block 42 is rotatably connected in one of the rotating grooves 41, and a lead screw 43 is rotatably connected in the connecting block 42. A nut 44 is rotatably connected in the other rotating groove 41, and the lead screw 43 and the nut 44 are screw driven.

[0059] When the packing material has been used for an extended period or is highly contaminated, simple rinsing is insufficient for thorough cleaning. Therefore, all packing material within the mounting frame 22 must be disassembled, and then soaked for deep cleaning. First, the operator unfolds the sliding rail 26, connecting piece 32, and support leg 3. Then, using tools, the screw 43 is adjusted to change the angle between the two support legs 3 until the sliding rail 26 is flush with the push-pull groove 23 on the mounting plate 2. Next, the operator manually opens the opening / closing door 25 and pulls the mounting frame 22, causing it to move onto the sliding rail 26. Then, the operator adjusts the screw 43 again. The rotation of the screw 43 creates a helical drive between the screw 43 and the nut 44. Because the bottom of the support leg 3... Roller 4 is in contact with the ground. Therefore, after the spacing between the two support legs 3 is adjusted, the support height of the support legs 3 on the connecting piece 32 gradually decreases, causing the end of the translation rail 26 away from the tower body 1 to gradually tilt towards the ground. At this time, under the action of gravity, the mounting frame 22 has a tendency to slide towards the ground. When the height of the end of the translation rail 26 is reduced to a suitable position, the staff can release the manual fixing of the mounting frame 22. Under the action of gravity and the guiding action of the translation rail 26, the mounting frame 22 can be slid down to the ground, completing the disassembly of the mounting frame 22. During installation, only the reverse operation is required. Therefore, the setting of the screw 43 effectively enhances the support and guiding role of the translation rail 26 and the support legs 3 on the mounting frame 22, enhances the convenience of disassembling the mounting frame 22, and facilitates the overall loading and unloading of the packing.

[0060] In a preferred embodiment of the present invention, the auxiliary flushing assembly includes an auxiliary plate 5, which is hinged to the translation rail 26;

[0061] The guide rod 51 has a storage groove 52 on one side of the auxiliary plate 5. A rotating block 53 is hinged in the storage groove 52. The guide rod 51 is rotatably mounted on the rotating block 53. The guide rod 51 has a reciprocating thread.

[0062] A paddle 54 is mounted on the guide rod 51, and the paddle 54 is helically connected to the guide rod 51.

[0063] During routine cleaning and maintenance of the packing, the worker moves the mounting frame 22 onto the platform consisting of the support leg 3 and the translation rail 26. Then, the worker flips the auxiliary plate 5 to make it vertical. Next, the worker manually rotates the guide rod 51, causing it to rotate within the storage slot 52 until it rests on the top of the mounting frame 22. At this point, the worker manually rotates the guide rod 51, causing the lever 54 on it to have a tendency to rotate. However, because the lever 54 is in contact with the top of the packing, it cannot rotate. The lever 54 then rotates... The motion is linear, causing the paddle 54 to move linearly along the guide rod 51. During the installation of the mounting frame 22 and the packing, the packing is inserted parallel to the guide rod 51. This causes the paddle 54 to gradually contact multiple packings one by one during the linear motion. Under the paddle's movement and deformation, the top of the packing is pressed, deformed, and recovers its deformation in sequence, causing the end of the packing to vibrate and shake to a certain extent. This increases the probability of impurities and scale deposited on the packing falling off. Combined with cleaning methods such as water flushing, this effectively enhances the ease of cleaning the packing.

[0064] In a preferred embodiment of the present invention, both the end of the lead screw 43 and the end of the guide rod 51 are provided with insertion holes, which are used to connect to the crank handle;

[0065] By opening insertion holes at the ends of the lead screw 43 and guide rod 51, the lead screw 43 and guide rod 51 can be connected to tools such as a crank handle using the insertion holes. This allows the lead screw 43 and guide rod 51 to be driven to rotate more conveniently and easily using tools such as a crank handle, further enhancing the ease of use of the convenient loading component and auxiliary flushing component.

[0066] In a preferred embodiment of the present invention, the paddle 54 is made of multiple elastic metal sheets welded together, and two adjacent elastic metal sheets are connected only at their top ends;

[0067] By sequentially welding multiple elastic metal sheets to form a scraper 54, with the tops of the multiple elastic metal sheets welded but the bottoms not connected, the bottom of the scraper 54 can deform to different degrees when it scrapes against the top of the packing during the movement of the scraper 54. This makes it easier to scrape the top of the packing, and the degree of deformation of the scraper is increased. The degree of deformation between different positions has less mutual influence, thereby enhancing the applicability of the scraper in use.

[0068] In a preferred embodiment of the present invention, the mounting frame 22 is hinged to a frame 6 and an end cap 61. The end caps 61 are symmetrically mounted on the side of the frame 6 near the inner wall of the tower body 1, and the two end caps 61 are connected by a rope knot.

[0069] By disassembling the mounting frame 22 into a frame body 6 and end caps 61, with the end caps 61 symmetrically hinged to the frame body 6, after the packing is filled in the mounting frame 22, the end caps 61 are closed together, causing the end caps 61 to squeeze the packing in the frame body 6, thus making the packing in the mounting frame 22 fit tightly. Then, when cleaning the packing, the knots can be untied or loosened manually, increasing the movable distance between the two end caps 61, which in turn causes the packing in the frame body 6 to move towards the end caps 61, thereby reducing the fit of the packing and increasing the gap between the packing. Combined with the scraping of the packing by the scraper, the gap between the scraped packing and the adjacent packing is further increased, making it easier for scale, impurities, etc., to fall through the gaps in the packing, further enhancing the cleaning effect on the packing. At the same time, when the movable distance of the packing increases, the deformation and vibration of the packing are increased when the scraper scrapes the packing, further enhancing the cleaning effect on the packing.

[0070] In a preferred embodiment of the present invention, the auxiliary plate 5 has an extension groove 62 on the side away from the storage groove 52, and the extension groove 62 is connected to the translation rail 26.

[0071] By opening an extension groove 62 on the auxiliary plate 5, when the mounting frame 22 and the filler need to be completely disassembled, the presence of the auxiliary plate 5 can work with the translation rail 26 to extend the guide length of the mounting frame 22, and the auxiliary plate 5 and the translation rail 26 can rotate relative to each other, further enhancing the flexibility of disassembling the mounting frame 22.

[0072] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
