Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model discloses a closed-loop counterflow cooling tower, including a cooling tower body 1. A filter box 201 is fixedly installed on one side of the cooling tower body 1. Slide grooves are provided on the top and bottom of one side of the inner wall of the filter box 201, and sliders 202 are movably installed in the slide grooves. Filter plates 203 are fixedly installed between the sliders 202. A handle 204 is fixedly installed in the middle of the front of the filter plate 203. A first screw 301 is movably installed on one side of the top of the filter box 201. One end of the first screw 301 is fixedly connected to the output shaft of a motor 302. A connecting rod 303 is movably installed outside the first screw 301. Moving rods 304 are fixedly installed on the front and back of the connecting rod 303. A moving tube 305 is provided at the bottom of the moving rod 304. Connecting blocks 306 are fixedly installed at the front and rear of the top of the moving tube 305. Openings are provided on both sides of the connecting blocks 306. The device has a screw hole, and a second screw 307 is movably installed inside the screw hole. A hexagonal nut 308 is fixedly installed at one end of the second screw 307. A protective shell 309 is movably installed outside the hexagonal nut 308. A hexagonal groove adapted to the hexagonal nut 308 is opened on one side of the protective shell 309. The protective shell 309 and the hexagonal nut 308 are connected by a movable insertion. An L-shaped rod 310 is fixedly installed on the top of the protective shell 309. A movable plate 311 is fixedly installed at one end of the L-shaped rod 310. A return spring 312 is installed on the side of the movable plate 311 near the L-shaped rod 310. The return spring 312 is sleeved with the L-shaped rod 310. A rotating seat 313 is movably installed outside the movable plate 311. The rotating seat 313 is slidably connected to the movable plate 311. The rotating seat 313 is rotatably connected to the connecting block 306.

[0022] Specifically, the motor 302 is fixedly connected to the cooling tower body 1 via an L-shaped plate.

[0023] In this embodiment, by setting up the cooling tower body 1 and the motor 302, the L-shaped plate provides stable support for the motor 302, enabling it to maintain normal operation.

[0024] Specifically, brush bristles 401 are fixedly provided on the upper and lower parts of the moving tube 305 near the filter plate 203.

[0025] In this embodiment, by setting bristles 401, when the bristles 401 move along the surface of the filter plate 203 with the movement of the moving tube 305, the dust and impurities on the surface of the filter plate 203 can be effectively cleaned, thereby realizing automatic cleaning of the filter plate 203.

[0026] Specifically, a dust suction hole 402 is provided in the middle of the side of the moving tube 305 near the filter plate 203.

[0027] In this embodiment, by setting up a moving tube 305 and a dust suction hole 402, the cleaned dust and dust attached to the brush bristles 401 can enter the moving tube 305 through the dust suction hole 402 to prevent it from scattering everywhere, thereby further improving the cleaning effect.

[0028] Specifically, a suction pipe 403 is fixedly installed on the other side of the moving pipe 305.

[0029] In this embodiment, by setting up a suction pipe 403, the suction pipe 403 can be connected to the pipe of an external vacuum cleaner, thereby achieving the purpose of removing dust.

[0030] Specifically, each of the bottom sides of the movable rod 304 is provided with a slot 404 that is adapted to the second screw 307, and the connection between the slot 404 and the second screw 307 is a movable insertion.

[0031] In this embodiment, by setting a second screw 307 and a slot 404, the second screw 307 is fully inserted into the slot 404, so that the moving rod 304 is tightly connected with the connecting block 306, thus completing the fixed installation of the moving tube 305.

[0032] When cleaning the filter plate 203 during use, rotate the second screw 307 until one end is fully inserted into the slot 404, thereby tightly connecting the moving rod 304 to the connecting block 306. Then, pull the L-shaped rod 310 away from the connecting block 306. The protective shell 309 and the moving plate 311 move accordingly, and the return spring 312 deforms. When the bottom of the protective shell 309 is higher than the top of the hexagonal nut 308, rotate the L-shaped rod 310. L-shaped rod 310 drives movable plate 311 to rotate, causing rotating seat 313 to rotate within connecting block 306 until protective shell 309 aligns with hexagonal nut 308. L-shaped rod 310 is then released. Under the elastic force of return spring 312, movable plate 311 drives L-shaped rod 310 and protective shell 309 to move, thereby allowing hexagonal nut 308 to insert into the hexagonal groove of protective shell 309, achieving the purpose of limiting the hexagonal nut 308 and enhancing the connection between movable rod 304 and... The connection of the connecting block 306 ensures stability, connecting the external vacuum cleaner pipe to the suction pipe 403. Starting the motor 302 causes the output shaft of the motor 302 to rotate the first screw 301, causing the connecting rod 303 and the moving rod 304 to move vertically, and consequently the connecting block 306 and the moving pipe 305. This allows the brush bristles 401 to clean the surface of the filter plate 203. Under the action of the vacuum cleaner, the cleaned dust is drawn into the moving pipe 305 through the suction hole 402 and finally discharged from the suction pipe 403. When deep cleaning or replacement of the filter plate 203 is required, pull the handle 204. With the cooperation of the slider 202, the filter plate 203 is pulled out of the filter box 201, achieving the purpose of disassembling the filter plate 203. At this time, the operator can perform deep cleaning or replacement of the filter plate 203. After the operation is completed, insert the filter plate 203 into the filter box 201, and the slider 202 slides in the groove, thus completing the installation of the filter plate 203.

[0033] In summary, this closed-loop counterflow cooling tower, by setting up a slider 202 and a handle 204, allows the filter plate 203 to be pulled out of the filter box 201 by pulling the handle 204 with the cooperation of the slider 202, thus disassembling the filter plate 203. Conversely, the filter plate 203 can be installed by pulling the handle 204. This achieves rapid disassembly and installation of the filter plate 203, greatly facilitating deep cleaning or replacement of the filter plate 203. It not only helps ensure that the filter plate 203 always maintains strong filtration performance, guarantees filtration effect, and extends the service life of the filter plate 203, but also simplifies the maintenance process of the filter plate 203, reduces resource waste, and lowers the cost of replacing the filter plate 203. By setting up a protective shell 309, an L-shaped rod 310, a moving plate 311, a return spring 312, and a rotating seat 313, the moving rod 304 is tightly connected to the connecting block 306, allowing it to move away from the connecting block. Pulling one side of the connecting block 306 pulls the L-shaped rod 310, causing the protective shell 309 and the moving plate 311 to move accordingly. The return spring 312 deforms. When the bottom of the protective shell 309 is higher than the top of the hexagonal nut 308, the L-shaped rod 310 is rotated. The L-shaped rod 310 drives the moving plate 311 to rotate, and the rotating seat 313 rotates within the connecting block 306 until the protective shell 309 is aligned with the hexagonal nut 308. The L-shaped rod 310 is then released. Under the elastic force of the return spring 312, the moving plate 311 drives the L-shaped rod 310 and the protective shell 309 to move, thereby allowing the hexagonal nut 308 to be inserted into the hexagonal groove of the protective shell 309. This achieves the purpose of limiting the hexagonal nut 308, effectively reducing the risk of the hexagonal nut 308 loosening or falling off, ensuring the stability of the connection between the moving rod 304 and the connecting block 306, and thus improving the cleaning effect of the bristles 401.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
