[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a water-saving and mist-eliminating device for a mechanical ventilation cooling tower, comprising: a support frame, a tower body and a packing frame;

[0007] The support frame is connected to a tower body, and the support frame serves as a supporting foundation. The tower body is connected to a filling frame, and the filling frame is connected to a filling material. The first hollow plates are embedded in the upper and lower sides of the filling frame.

[0008] The air inlet louver is embedded in one side of the tower body. The bottom of the tower body is connected to a sealing door, and the upper part of the tower body is connected to a fan.

[0009] Preferably, a guide plate is connected to one side of the filling frame, the guide plate is slidably connected in a guide rail, and the guide rail is connected to the inner wall of the tower body;

[0010] An L-shaped angle plate is connected above the guide rail, a through slot is provided in the L-shaped angle plate, a T-shaped docking rod is connected through the through slot, a bearing is connected to the end of the T-shaped docking rod, the bearing is connected in a groove, the groove is provided on the upper surface of the packing frame, a torsion spring is connected above the bearing, and one end of the torsion spring is connected to the T-shaped docking rod.

[0011] Preferably, the end length of the T-shaped butt joint rod is greater than the inner length of the through slot, and the end length of the T-shaped butt joint rod is less than the inner width of the through slot.

[0012] Preferably, a T-shaped guide rod is connected to the inner wall of the filling frame, the T-shaped guide rod penetrates and is connected in the guide hole, the guide hole is provided in the push plate, and the push plate is snap-fitted and connected in the filling frame.

[0013] Preferably, a threaded hole is provided in the push plate, a threaded rod is threadedly connected in the threaded hole, a servo motor is connected to one end of the threaded rod, and the servo motor is connected in a placement cavity, and the placement cavity is provided on the inner wall of the filling frame.

[0014] Preferably, the guide hole, the push plate, the threaded hole, the threaded rod and the servo motor form a linkage structure, and the cross-sectional area of ​​the push plate is equal to the cross-sectional area inside the filling frame.

[0015] Preferably, a support frame is connected above the filling frame, a telescopic rod is embedded above the support frame, a second hollow plate is connected to the end of the telescopic rod, and an insertion rod is connected below the second hollow plate.

[0016] Preferably, the support frame and the second hollow plate are symmetrically arranged in two groups about the central axis of the filling frame.

[0017] A method for using a water-saving and mist-eliminating device for a mechanical ventilation cooling tower comprises the following steps:

[0018] S01: Open the sealing door and push the stuffing frame into the tower body from top to bottom. When the stuffing frame moves upward to a certain height, the guide plates on both sides of the stuffing frame slide into the guide rails on both sides at the same time to limit the stuffing frame and prevent it from shaking.

[0019] S02: When the guide plate has not completely slid into the guide rail, manually rotate the T-shaped butt joint rod so that the end of the T-shaped butt joint rod can pass through the through slot. When the guide plate has completely slid into the guide rail, the end of the T-shaped butt joint rod just passes through the through slot. Loosen the T-shaped butt joint rod. Under the action of the torsion spring, the T-shaped butt joint rod automatically resets and then abuts against the L-shaped angle plate, thereby facilitating the installation of the packing frame. When disassembling, you only need to rotate the T-shaped butt joint rod again so that the end of the T-shaped butt joint rod can be withdrawn from the through slot.

[0020] S03: After the installation is completed, start the fan, and the air enters the tower body through the air inlet louvers on both sides, and then performs heat exchange cooling. At the same time, the mist water generated by the heat exchange passes through the packing frame from top to bottom and is absorbed by the internal packing. When the internal packing needs to be replaced, start the servo motor, and the servo motor drives the threaded rod to rotate clockwise. Since the threaded rod is threadedly connected to the push plate through the threaded hole, and the push plate is slidably connected to the T-shaped guide rod through the guide hole, when the threaded rod rotates, the push plate will move outward along the packing frame, and then push the internal packing out;

[0021] S04: The servo motor is started again, and the servo motor drives the threaded rod to rotate counterclockwise to reset the push plate. After the filler inside the filler frame is cleaned, the telescopic rod is started, and the end of the telescopic rod is extended to drive the second hollow plate to move downward, so that the end of the insertion rod is inserted into the aperture inside the first hollow plate, and the filler contaminated in the aperture of the first hollow plate is withdrawn, and the servo motor is started again to clean the inside of the filler frame again;

[0022] S05: Finally, pour new filler back into the filler frame.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: by sliding the guide plates on both sides of the packing frame into the guide rails from bottom to top, and resetting the T-shaped docking rod through the through slot, the packing frame is easily installed, and by rotating the threaded rod, the push plate is driven to move along the packing frame, and the packing in the packing frame is pushed out, so as to facilitate the removal of the packing, and the second hollow plate is driven downward by the telescopic rod to enable the insertion rod to be inserted into the aperture in the first hollow plate, thereby preventing the first hollow plate from being blocked. The specific contents are as follows:

[0024] 1. First, open the sealing door and push the stuffing frame into the tower body from top to bottom. The guide plates on both sides of the stuffing frame slide into the guide rails on both sides at the same time. Rotate the T-shaped docking rod. When the guide plate slides completely into the guide rail, the end of the T-shaped docking rod just passes through the through slot. Loosen the T-shaped docking rod. The T-shaped docking rod resets itself under the action of the torsion spring and then rests on the L-shaped angle plate, making it easier to install the stuffing frame.

[0025] 2. When the internal filler needs to be replaced, start the servo motor, which drives the threaded rod to rotate clockwise, and the push plate will move outward along the filler frame to push out the internal filler, making it easier to take out the material. Then start the servo motor again, which drives the threaded rod to rotate counterclockwise to reset the push plate. Finally, pour new filler back into the filler frame, making it easier to replace the filler.

[0026] 3. After cleaning the filler inside the filler frame, start the telescopic rod, the end of the telescopic rod extends, driving the second hollow plate to move downward, so that the end of the insertion rod is inserted into the aperture inside the first hollow plate, and the filler contaminated in the aperture of the first hollow plate is removed, thereby facilitating the cleaning of the first hollow plate.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-4 , the present invention provides a technical solution: a water-saving and mist-eliminating device for a mechanical ventilation cooling tower, comprising: a support frame 1, a tower body 2 and a packing frame 3;

[0034] A tower body 2 is connected to the support frame 1, and the support frame 1 serves as a supporting base. A filling frame 3 is connected inside the tower body 2, and a filling 4 is connected inside the filling frame 3. A first hollow plate 5 is embedded on the upper and lower sides of the filling frame 3. An air inlet louver 201 is embedded on one side of the tower body 2. A sealing door 202 is connected to the bottom of the tower body 2, and a fan 203 is connected to the top of the interior of the tower body 2.

[0035] A guide plate 6 is connected to one side of the packing frame 3. The guide plate 6 is slidably connected to the guide rail 7. The guide rail 7 is connected to the inner wall of the tower body 2. An L-shaped angle plate 8 is connected to the top of the guide rail 7. A through slot 9 is provided in the L-shaped angle plate 8. A T-shaped docking rod 10 is connected through the through slot 9. A bearing 11 is connected to the end of the T-shaped docking rod 10. The bearing 11 is connected to the groove 12. The groove 12 is provided on the upper surface of the packing frame 3. A torsion spring 13 is connected to the top of the bearing 11. One end of the torsion spring 13 is connected to the T-shaped docking rod 10. The end length of the T-shaped docking rod 10 is greater than the inner length of the through slot 9, and the end length of the T-shaped docking rod 10 is less than the inner width of the through slot 9, so that the T-shaped docking rod 10 can pass through the through slot 9 after rotation, and cannot pass through the through slot 9 after reset. The packing frame 3 is easily installed by sliding the guide plates 6 on both sides of the packing frame 3 into the guide rail 7 from bottom to top and resetting the T-shaped docking rod 10 through the through slot 9.

[0036] A T-shaped guide rod 14 is connected to the inner wall of the packing frame 3. The T-shaped guide rod 14 penetrates and is connected in the guide hole 15. The guide hole 15 is provided in the push plate 16. The push plate 16 is connected in the packing frame 3. A threaded hole 17 is provided in the push plate 16. A threaded rod 18 is threadedly connected in the threaded hole 17. A servo motor 19 is connected at one end of the threaded rod 18. The servo motor 19 is connected in the placement cavity 20. The placement cavity 20 is provided on the inner wall of the packing frame 3 to prevent the servo motor 19 from being exposed in the tower body 2. The guide hole 15, the push plate 16, the threaded hole 17, the threaded rod 18 and the servo motor 19 form a linkage structure, and the cross-sectional area of ​​the push plate 16 is equal to the cross-sectional area inside the packing frame 3, so that when the push plate 16 moves, the packing 4 in the packing frame 3 can be completely pushed out. By rotating the threaded rod 18, the push plate 16 is driven to move along the packing frame 3, and then the packing 4 in the packing frame 3 is pushed out, so that the packing 4 is easily taken out.

[0037] A support frame 21 is connected above the filling frame 3, a telescopic rod 22 is embedded above the support frame 21, a second hollow plate 23 is connected to the end of the telescopic rod 22, and an insertion rod 24 is connected below the second hollow plate 23. The support frame 21 and the second hollow plate 23 are symmetrically arranged in two groups about the central axis of the filling frame 3, and the first hollow plates 5 on the upper and lower sides can be cleaned. The second hollow plate 23 is driven downward by the telescopic rod 22, and the insertion rod 24 can be inserted into the aperture in the first hollow plate 5, thereby preventing the first hollow plate 5 from being blocked.

[0038] A method for using a water-saving and mist-eliminating device for a mechanical ventilation cooling tower comprises the following steps:

[0039] S01: Open the sealing door 202, push the packing frame 3 from top to bottom into the tower body 2, and when the packing frame 3 moves upward to a certain height, the guide plates 6 on both sides of the packing frame 3 slide into the guide rails 7 on both sides at the same time to limit the packing frame 3 and prevent the packing frame 3 from shaking;

[0040] S02: When the guide plate 6 has not completely slid into the guide rail 7, the T-shaped docking rod 10 is manually rotated so that the end of the T-shaped docking rod 10 can pass through the through slot 9. When the guide plate 6 completely slides into the guide rail 7, the end of the T-shaped docking rod 10 just passes through the through slot 9. The T-shaped docking rod 10 is loosened. Under the action of the torsion spring 13, the T-shaped docking rod 10 automatically resets and then abuts against the L-shaped angle plate 8, thereby facilitating the installation of the packing frame 3. When disassembling, it is only necessary to rotate the T-shaped docking rod 10 again so that the end of the T-shaped docking rod 10 can be withdrawn from the through slot 9.

[0041] S03: Secondly, after the installation is completed, the fan 203 is started, and the air enters the tower body 2 through the air inlet louvers 201 on both sides, and then heat exchange and cooling are performed. At the same time, the mist water generated by the heat exchange passes through the packing frame 3 from top to bottom and is absorbed by the internal packing 4. When the internal packing 4 needs to be replaced, the servo motor 19 is started, and the servo motor 19 drives the threaded rod 18 to rotate clockwise. Since the threaded rod 18 is threadedly connected to the push plate 16 through the threaded hole 17, and the push plate 16 is slidably connected to the T-shaped guide rod 14 through the guide hole 15, therefore, when the threaded rod 18 rotates, the push plate 16 will move outward along the packing frame 3, and then push the internal packing 4 out, so as to facilitate material removal;

[0042] S04: Start the servo motor 19 again, the servo motor 19 drives the threaded rod 18 to rotate counterclockwise, resets the push plate 16, and after cleaning the filler 4 inside the filling frame 3, starts the telescopic rod 22, the end of the telescopic rod 22 extends, drives the second hollow plate 23 to move downward, and inserts the end of the insertion rod 24 into the aperture inside the first hollow plate 5, and removes the filler 4 contaminated in the aperture of the first hollow plate 5, thereby facilitating the cleaning of the first hollow plate 5, and repeatedly starts the servo motor 19 to clean the inside of the filling frame 3 again.

[0043] S05: Finally, new filler 4 is poured back into the filler frame 3, thereby facilitating replacement of the filler 4.

[0044] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
