Description

Technical Field

[0001] This utility model belongs to the field of cooling water tower technology, specifically relating to a descaling mechanism applied to cooling water towers. Background Technology

[0002] A cooling tower is a device that cools water, in which the water exchanges heat and mass with the flowing air, causing the water temperature to drop. It is widely used in air conditioning circulating water systems and industrial circulating water systems. Under certain water treatment conditions, cooling effect is one of the important performance characteristics of a cooling tower. When selecting a cooling tower, the main considerations are the degree of cooling, the cooling water volume, and whether there are any special requirements for the wet-bulb temperature. It is usually installed in a well-ventilated location.

[0003] Patent application number 202120679219.4 discloses a descaling mechanism for cooling water towers, including a cooling water tower body and a water tank. Multiple reinforcing rods are symmetrically arranged at the top of the interior of the cooling water tower body. A fixing block is fixed at the intersection of the multiple reinforcing rods. A threaded rod is rotatably arranged between the fixing block and the cooling water tower body. A lifting block is threadedly connected to the threaded rod. Multiple connecting rods are fixed on the side wall of the lifting block.

[0004] The aforementioned descaling mechanism applied to cooling towers uses vertically moving descaling units to scrub the inner wall of the cooling tower. However, since the lateral position of the descaling unit in the cooling tower is constant, the surfaces of the polishing stone and wiping cloth that make up the descaling unit have an uneven structure. The depressions on the descaling unit will cause linear dirt residue to remain on the inner wall of the cooling tower after descaling, resulting in poor descaling and cleaning effect on the inner wall of the cooling tower. Utility Model Content

[0005] (1) Technical problems to be solved In view of the shortcomings of the prior art, the purpose of this utility model is to provide a descaling mechanism for cooling water towers. This descaling mechanism for cooling water towers aims to solve the technical problem that in the prior art, the position of the descaling unit is constant, and the depression on the descaling unit will cause linear dirt residue on the inner wall of the cooling water tower after descaling and cleaning, resulting in poor descaling and cleaning effect on the inner wall of the cooling water tower.

[0006] (2) Technical solution To solve the above-mentioned technical problems, this utility model provides a descaling mechanism for cooling towers, including a cooling tower body and a fixing plate embedded and fixed to the top of the inner wall of the cooling tower body. A threaded rod is welded and fixed at the center of the bottom end face of the fixing plate, and a rotating ring is installed at the bottom end of the fixing plate through a bearing. A cleaning plate is threadedly sleeved at the top end of the threaded rod. Drive rods inserted into the cleaning plate are welded and fixed on both sides of the bottom end face of the rotating ring. A cleaning ring that is tightly connected to the inner wall of the cooling tower body is welded and fixed on the cleaning plate.

[0007] When using this technical solution, a second motor is fixedly installed at the bottom of the cooling tower body. After the second motor is started, it drives the rotating shaft and two drive rods to rotate on the outside of the threaded rod. During the rotation, it drives the cleaning plate and cleaning ring to rotate. As the cleaning plate rotates, it moves downward on the threaded rod, causing the cleaning ring to move downward synchronously during the rotation and wiping process. This facilitates vertical movement during rotation to remove scale from the inner wall of the cooling tower body, avoiding the problem of poor scale removal effect on the inner wall of the cooling tower caused by the constant position of the cleaning ring. A support plate is rotatably engaged at the bottom of the threaded rod. The ball bearings at both ends of the support plate contact the inner wall of the cooling tower body to position the bottom of the threaded rod. At the same time, the drive rod drives the support plate to rotate synchronously during the rotation. The support plate does not move vertically on the threaded rod during the rotation, improving the stability of the threaded rod.

[0008] Preferably, a second motor is fixedly installed at the bottom of the cooling tower body, and a rotating shaft is rotatably connected to the bottom wall of the cooling tower body through a bearing.

[0009] Furthermore, the bottom end of the threaded rod is rotatably engaged with a support plate via a protrusion, and both ends of the support plate are embedded with ball bearings that contact the inner wall of the cooling water tank body.

[0010] Furthermore, the bottom ends of both drive rods pass through the support plate and are welded and fixed to the rotating shaft, and the shaft of the second motor is fixed to the rotating shaft.

[0011] Furthermore, a water outlet pipe is fixedly installed at the bottom of the outer wall of the cooling tower body, and a water inlet pipe is installed at the top of the outer wall of the cooling tower body.

[0012] Furthermore, the bottom of the cooling tower is provided with an air inlet slot, and the first motor is fixedly installed in the air outlet cavity of the main body of the cooling tower through a support plate.

[0013] Furthermore, the shaft of the first motor is fixedly mounted with blades through the support plate, and the outer wall of the cleaning ring is respectively glued and fixed with a wiping cloth and a polishing stone.

[0014] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features a second motor fixedly installed at the bottom of the cooling tower body. After starting, the second motor drives the rotating shaft and two drive rods to rotate on the outside of the threaded rod. During the rotation, the cleaning plate and cleaning ring rotate. As the cleaning plate rotates, it moves downward on the threaded rod, causing the cleaning ring to move downward synchronously during the rotation and wiping process. This facilitates vertical movement during rotation to remove scale from the inner wall of the cooling tower body, avoiding the problem of poor scale removal effect on the inner wall of the cooling tower due to the constant position of the cleaning ring. A support plate is rotatably engaged at the bottom of the threaded rod. The balls at both ends of the support plate contact the inner wall of the cooling tower body to position the bottom of the threaded rod. At the same time, the drive rod rotates synchronously with the support plate. The support plate does not move vertically on the threaded rod during rotation, thus improving the stability of the threaded rod. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0019] This specific embodiment is a descaling mechanism applied to a cooling water tower, and its structural schematic diagram is shown below. Figures 1 to 4 As shown, the system includes a cooling tower body 1 and a fixing plate 12 embedded and fixed to the top of the inner wall of the cooling tower body 1. A threaded rod 14 is welded and fixed at the center of the bottom end face of the fixing plate 12, and a rotating ring 13 is installed at the bottom end of the fixing plate 12 through a bearing. A cleaning plate 10 is threadedly sleeved at the top end of the threaded rod 14. Drive rods 15 inserted into the cleaning plate 10 are welded and fixed on both sides of the bottom end face of the rotating ring 13. A cleaning ring 9 that is tightly connected to the inner wall of the cooling tower body 1 is welded and fixed on the cleaning plate 10. After the second motor 6 is started, it drives the rotating shaft 7 and the two drive rods 15 to rotate outside the threaded rod 14. During the rotation, it drives the cleaning plate 10 and the cleaning ring 9 to rotate. During the rotation, the cleaning plate 10 moves downward on the threaded rod 14, so that the cleaning ring 9 moves downward synchronously during the rotation and wiping process. This facilitates vertical movement during the rotation to remove scale from the inner wall of the cooling tower body 1, avoiding the problem of poor descaling effect caused by the constant position of the cleaning ring 9.

[0020] A second motor 6 is fixedly installed at the bottom of the cooling tower body 1, and a rotating shaft 7 is rotatably connected to the bottom wall of the cooling tower body 1 via a bearing. A sealed bearing is installed on the rotating shaft 7 to keep the bottom of the cooling tower body 1 sealed. A support plate 8 is rotatably engaged at the bottom of the threaded rod 14 via a protrusion. Both ends of the support plate 8 are embedded with ball bearings 16 that contact the inner wall of the cooling water tank body. The bottom ends of the two drive rods 15 pass through the support plate 8 and are welded and fixed to the rotating shaft 7. The shaft of the second motor 6 is fixed to the rotating shaft 7. A wiping cloth and a polishing stone are respectively glued and fixed to the outer wall of the cleaning ring 9. The ball bearings 16 at both ends of the support plate 8 contact the inner wall of the cooling tower body 1 to position the bottom of the threaded rod 14. At the same time, the drive rod 15 drives the support plate 8 to rotate synchronously during rotation. The support plate 8 will not move vertically on the threaded rod 14 during rotation, which improves the stability of the threaded rod 14.

[0021] A water outlet pipe 4 is fixedly installed at the bottom of the outer wall of the cooling tower body 1, and a water inlet pipe 3 is installed at the top of the outer wall of the cooling tower body 1. Multiple spray holes are opened at the bottom of the end of the water inlet pipe 3 that extends into the cooling tower body. An air inlet slot 5 is opened at the bottom of the cooling tower. A first motor 2 is fixedly installed in the air outlet cavity of the cooling tower body 1 through a support plate. The shaft of the first motor 2 passes through the support plate and a blade 11 is fixedly installed. High-temperature water is input from the water inlet pipe 3 and sprayed out along the spray holes. When the first motor 2 drives the blade 11 to rotate, the external air is drawn in along the air inlet slot 5 to cool the high-temperature water and then discharged from the top of the cooling tower body 1.

[0022] Working principle: When using the device of this technical solution, the second motor 6 is started when descaling the inner wall of the cooling tower body 1. After starting, the second motor 6 drives the rotating shaft 7 and the two drive rods 15 to rotate on the outside of the threaded rod 14. During the rotation, the cleaning plate 10 and the cleaning ring 9 are rotated. During the rotation, the drive rod 15 drives the support plate 8 to rotate synchronously. The balls 16 at both ends of the support plate 8 contact the inner wall of the cooling tower body 1 to position the bottom of the threaded rod 14. During the rotation, the cleaning plate 10 moves downward on the threaded rod 14, so that the cleaning ring 9 moves downward synchronously during the rotation and wiping process. During the rotation, the vertical movement descals the inner wall of the cooling tower body 1.

[0023] All technical features in this embodiment can be freely combined according to actual needs.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
