Description

Technical Field

[0001] This utility model relates to the technical field of cooling towers, and in particular to a closed-loop cooling tower. Background Technology

[0002] A closed-circuit cooling tower is a variation and development of the traditional cooling tower. It is essentially a combination of an evaporative cooling tower and a wet cooling tower. It is a horizontal evaporative cooling tower where the process fluid flows inside the pipes and air flows outside, without contact between them. Water in a reservoir at the bottom of the tower is drawn by a circulating pump and sprayed evenly onto the outside of the pipes. Because it does not come into contact with the process fluid (hot water or refrigerant) or the outside air, it is a closed-circuit cooling tower, enhancing heat and mass transfer through water spraying.

[0003] Currently, when installing air intake grilles, they are fixed to the surrounding housing by multiple screws from all four sides of the grille. During installation, the grille needs to be accurately matched with the installation channel, and then the grille is fixed by hand while the screws are installed one by one. When disassembling, multiple screws need to be removed from the housing. This installation and disassembly method is relatively complicated and laborious, resulting in low efficiency in installing and removing air intake grilles, wasting a lot of workers' time, and increasing the labor intensity of workers. Utility Model Content

[0004] The purpose of this invention is to provide a closed-loop cooling tower to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is:

[0006] A closed-loop cooling tower includes: a grille disposed on one side of the cooling tower body; a connecting assembly disposed on the cooling tower body and the grille, the connecting assembly including: a horizontal plate fixedly disposed inside the cooling tower body; a shell fixedly disposed on one side of the grille; a sliding groove opened on one side of the shell; a locking block disposed inside the shell and slidably connected to the sliding groove; a rotating rod passing through the grille at one end and rotatably connected to the grille; a turntable fixedly disposed at one end of the rotating rod; and a sliding rod passing through a guide groove on the turntable at one end and fixedly connected to the locking block.

[0007] In some embodiments, one side of the card block is designed with a bevel.

[0008] In some embodiments, the inner wall of the cross plate and the outer wall of the housing are fitted together.

[0009] In some embodiments, the connecting assembly further includes a knob fixedly disposed at one end of the rotating rod.

[0010] In some embodiments, the connecting assembly further includes: inclined plates symmetrically fixed to one side of the housing.

[0011] In some embodiments, a spring-loaded assembly is provided on the horizontal plate. The spring-loaded assembly further includes: one end of a rod penetrating through the horizontal plate; a plate fixedly disposed at one end of the rod; and a spring sleeved on the outside of the rod, with both ends fixedly connected to the plate and the horizontal plate respectively.

[0012] In some embodiments, the rebound assembly further includes: a groove formed on one side of the cross plate; and a rubber plate fixedly disposed at one end of the rod.

[0013] In some embodiments, four sets of rebound components are symmetrically arranged.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The connecting assembly on this cooling tower, by controlling the rotation of a rotating rod, can drive a turntable to rotate, causing a sliding rod inside the turntable to move. This, in turn, moves a locking block inside a sliding groove, extending from the inside of the housing to prevent the housing from separating from the horizontal plate, thus completing the installation and removal of the grille. Compared to existing devices, this method is more convenient and efficient in installing and removing the grille. Attached Figure Description

They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Given the current technology, the air intake grille is currently fixed to the surrounding housing by multiple screws from all four sides of the grille during installation. During installation, the grille needs to be accurately matched with the installation channel, and then the grille is fixed by hand while the screws are installed one by one. During disassembly, multiple screws need to be removed from the housing. This installation and disassembly method is relatively complicated and laborious, resulting in low efficiency in installing and removing air intake grilles, wasting a lot of workers' time, and increasing the labor intensity of workers.

[0026] When it is necessary to install the grille 12, one end of the housing 22 can be inserted into the inner side of the horizontal plate 21 to restrict the rotation of the grille 12. Then, grasp the rotating rod 25 and rotate it, which can drive the turntable 26 to rotate and drive the slide rod 27 to slide inside the guide groove of the turntable 26. Because one end of the slide rod 27 is fixedly connected to the locking block 24, when the slide rod 27 moves, it can drive the locking block 24 to slide and retract into the housing 22 inside the slide groove 23. Then, insert the housing 22 completely into the interior of the horizontal plate 21. Then, rotate the rotating rod 25 in the opposite direction, and then use the turntable 26 to drive the slide rod 27 to move so that the locking block 24 extends out from the interior of the housing 22, which can prevent the housing 22 from detaching from the interior of the horizontal plate 21, thus completing the installation.

[0027] As shown in the attached drawings, this utility model embodiment provides a closed cooling tower, including: a grille 12 disposed on one side of a cooling tower body 11; a connecting assembly 2 disposed on the cooling tower body 11 and the grille 12, the connecting assembly 2 including: a horizontal plate 21 fixedly disposed inside the cooling tower body 11; a shell 22 fixedly disposed on one side of the grille 12; a sliding groove 23 opened on one side of the shell 22; a locking block 24 disposed inside the shell 22 and slidably connected to the sliding groove 23; a rotating rod 25 passing through the grille 12 at one end and rotatably connected to the grille 12; a turntable 26 fixedly disposed at one end of the rotating rod 25; and a sliding rod 27 passing through a guide groove on the turntable 26 at one end and fixedly connected to the locking block 24.

[0028] Specifically, the closed-circuit cooling tower body 11 can be understood as a high-efficiency device that combines the features of a "water-cooled radiator" and a "traditional open-circuit cooling tower".

[0029] Core design goals

[0030] The core design goal of a closed-circuit cooling tower is to circulate the process fluid (usually water or oil) within a completely closed piping system, achieving cooling through indirect heat exchange with external spray water and air. This ensures the process fluid remains clean, uncontaminated, scale-free, and undamaged. A model example is BNF-100RT-S.

[0031] The grille 12 of the cooling tower body 11, also commonly referred to as the air inlet protection net or maintenance walkway grille, is a common and important component on the exterior and interior of the cooling tower.

[0032] When installing the grille 12, one end of the housing 22 can be inserted into the inside of the horizontal plate 21 to restrict the rotation of the grille 12. Then, the rotating rod 25 can be gripped and rotated to drive the turntable 26 to rotate and drive the sliding rod 27 to slide inside the guide groove of the turntable 26. Because one end of the sliding rod 27 is fixedly connected to the locking block 24, when the sliding rod 27 moves, it can drive the locking block 24 to slide and retract into the housing 22 inside the sliding groove 23. Then, the housing 22 is fully inserted into the inside of the horizontal plate 21. Then, the rotating rod 25 is rotated in the opposite direction, and the turntable 26 is used to drive the sliding rod 27 to move so that the locking block 24 extends out from the inside of the housing 22, which can prevent the housing 22 from detaching from the inside of the horizontal plate 21, thus completing the installation.

[0033] In some embodiments, one side of the card block 24 is designed with a bevel.

[0034] The inclined design allows the housing 22 to be directly inserted into the interior of the horizontal plate 21. During insertion, the locking block 24 is squeezed and retracted into the interior of the housing 22. While moving, it can drive the turntable 26 to rotate. After the housing 22 is inserted into the interior of the horizontal plate 21, the control rod 25 rotates to control the locking block 24 to extend out from the interior of the housing 22 to prevent the housing 22 from separating from the horizontal plate 21, thereby completing the installation.

[0035] In some embodiments, the inner wall of the horizontal plate 21 and the outer wall of the housing 22 are fitted together.

[0036] The fitted design allows for better restraint of the housing 22 after it is inserted into the horizontal plate. The housing 22 can sway inside the horizontal plate 21, which helps to maintain the stability of the grille 12.

[0037] In some embodiments, the connecting component 2 further includes a knob 28 fixedly disposed at one end of the rotating rod 25.

[0038] The knob 28 is designed for easy gripping and better control of the rotation of the lever 25. At the same time, the grooves on the surface of the knob 28 can increase friction when rotating.

[0039] In some embodiments, the connecting component 2 further includes: inclined plates 29 symmetrically fixedly disposed on one side of the housing 22.

[0040] The design of the sloping plate 29 makes it relatively easier for the housing 22 to be inserted into the horizontal plate 21.

[0041] In some embodiments, a spring-loaded assembly 3 is provided on the horizontal plate 21. The spring-loaded assembly 3 further includes: a rod 31 with one end penetrating through the horizontal plate 21; a plate 32 fixedly disposed at one end of the rod 31; and a spring 33 sleeved on the outside of the rod 31, with both ends fixedly connected to the plate 32 and the horizontal plate 21 respectively.

[0042] After the grille 12 is installed on one side of the cooling tower body 11, the push rod 31 will drive the plate 32 to move through the horizontal plate 21. While the plate 32 is moving, the spring 33 will be stretched. The force of the spring 33 retracting can make the horizontal plate 21 and the locking block 24 fit better, thereby increasing the friction and making it difficult for the locking block 24 to retract into the housing 22. When the locking block 24 retracts into the housing 22, the restriction of the housing 22 is released, the spring 33 retracts and drives the plate 32 to move, thereby pushing the grille 12 to move, making it easier for the housing 22 and the horizontal plate 21 to separate.

[0043] In some embodiments, the rebound assembly 3 further includes: a groove 34 formed on one side of the horizontal plate 21; and a rubber plate 35 fixedly disposed at one end of the rod 31.

[0044] The design of the groove 34 and the rubber plate 35 allows the grille 12 to fit better with the horizontal plate 21, while the rubber plate 35 can be moved into the groove 34. The soft material of the rubber plate 35 itself can reduce the impact force.

[0045] In some embodiments, four sets of the rebound components 3 are symmetrically arranged.

[0046] Four sets are provided to better push the grille 12, so that the card block 24 fits better with the horizontal plate 21.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
