Full-automatic flushing device for air cooling island finned tube bundle

Abstract

This utility model belongs to the technical field of rinsing devices, specifically a fully automatic rinsing device for air-cooled island finned tube bundles, including a nozzle and a moving plate. Limiting ring units are fixedly installed on both sides of the front of the moving plate. The nozzle is rotatably positioned between the limiting ring units. A fixed plate is welded to one side of the moving plate, and a rotating disk is installed on one side of the fixed plate. A protruding strip is welded to one side of the rotating disk. A motor is fixedly installed on the side of the fixed plate away from the rotating disk. Through the arrangement of the rotating disk, protruding strip, control components, gear components, and limiting ring units, the motor controls the rotation of the rotating disk. The protruding strip on the rotating disk causes the control components to move around an axis, and the gears rotate in both directions, thereby driving the nozzle to swing up and down. This changes the longitudinal position of the nozzle spraying water towards the air-cooled island fins, resulting in a better rinsing effect. This solves the problem of existing devices where the nozzle is fixed to the fixed plate and cannot swing up and down, thus limiting the rinsing effect.

Description

Technical Field

[0001] This utility model belongs to the technical field of rinsing devices, specifically a fully automatic rinsing device for air-cooled island finned tube bundles. Background Technology

[0002] Air-cooled islands are the main air-cooling devices in power plants, primarily used in coal-rich and water-scarce northern regions. Direct air-cooling technology offers advantages such as water conservation and small footprint. Air-cooled islands operate continuously exposed to the air, where fine sand, dust, and debris generated by strong winds accumulate on the radiator fins. This not only hinders heat exchange but also affects fan exhaust, leading to reduced heat exchange efficiency and, in severe cases, directly impacting normal power generation efficiency.

[0004] Existing devices, by setting up flushing nozzles facing the heat dissipation fins of the air-cooled island, can spray water onto the fins, but because the flushing nozzles are fixed to the fixed plate, they cannot swing up and down, and the longitudinal position of the water sprayed toward the air-cooled island fins cannot be changed, so the flushing effect needs to be improved. Therefore, in order to address the above problems, a fully automatic flushing device for air-cooled island fin tube bundles is proposed. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figure 1-5This utility model provides a fully automatic flushing device for air-cooled island finned tube bundles, including a nozzle 110 and a moving plate 111. All electrical components used in this utility model are commercially available, and their specific structures and working principles are existing technologies well-known to those skilled in the art, and therefore will not be described further here. Limiting ring units 200 are fixedly installed on both sides of the front of the moving plate 111. The nozzle 110 is rotatably positioned between the limiting ring units 200. A fixing plate 112 is welded and fixed to one side of the moving plate 111. A rotating disk 113 is provided on one side of the fixing plate 112. A protruding strip 114 is welded and connected to one side of the rotating disk 113. A motor 115 is fixedly installed on the side of the fixing plate 112 away from the rotating disk 113. The center of the rotating disk 113 is fixedly installed at the end of the motor 115. A control device is rotatably installed on one side of the fixing plate 112. The component 116 and the control component 116 pass through the protrusion 114. The end of the control component 116 is integrally mounted with a toothed component 117. A gear 118 is welded and fixed to one side of the nozzle 110. The gear 118 meshes with the toothed component 117. When using this device, first ensure that the water supply is supplied to the nozzle 110. Place the device next to the air-cooled island so that the nozzle 110 faces the air-cooled island fins. The motor 115 controls the rotating disk 113 to rotate. The protrusion 114 on the rotating disk 113 causes the control component 116 to move around the axis. Under the action of the toothed component 117, the gear 118 performs forward and reverse rotation, thereby driving the nozzle 110 to swing up and down. As a result, the longitudinal position of the nozzle 110 spraying water toward the air-cooled island fins is changed, and the rinsing effect is better. This solves the problem that the nozzle 110 of the existing device is fixed on the fixed plate and cannot swing up and down, so the rinsing effect needs to be improved.

[0027] Furthermore, nozzles 119 are uniformly and fixedly installed on the front side of the nozzle 110, and a translation plate 120 is provided on the back side of the moving plate 111. The moving plate 111 is installed on the translation plate 120. The sealing cover 126 is opened, and the water supply pipe is connected to the port of the nozzle 110 to supply water to the nozzle 110. Water is sprayed onto the air-cooled island fins through the nozzles 119 to achieve rinsing.

[0028] Furthermore, a fixed frame 122 is provided on the back of the translation plate 120. I-shaped rails 123 are welded and fixed to the top and bottom of the fixed frame 122. Sliding parts 124 are fixedly installed on the top and bottom of the back of the translation plate 120. The sliding parts 124 are slidably installed on the I-shaped rails 123. The arrangement of the I-shaped rails 123 and the sliding parts 124 allows the translation plate 120 to move horizontally on the fixed frame 122, so that the nozzle 110 sprays water to other positions of the air-cooled island fins.

[0029] Furthermore, a bolt 121 is provided through the front of the movable plate 111. The bolt 121 is threaded into the translation plate 120. The movable plate 111 is fixedly installed on the translation plate 120 by the bolt 121. The bolt 121 is used to fix the movable plate 111 on the translation plate 120, thereby achieving stable fixation of the movable plate 111.

[0030] Furthermore, a sealing cap 126 is threaded onto the end of the nozzle 110. The limiting ring unit 200 includes a first limiting member 210, which is fixedly mounted on the movable plate 111. The first limiting member 210 and the second limiting member 211 limit the nozzle 110. When the nozzle 110 needs to be replaced, the first limiting member 210 and the second limiting member 211 can be separated for replacement.

[0031] Furthermore, a second limiting component 211 is fixedly installed on the front of the first limiting component 210. A second bolt 212 is installed through the second limiting component 211. The second bolt 212 is threaded into the first limiting component 210. Both ends of the nozzle 110 pass through the first limiting component 210 and the second limiting component 211. The second bolt 212 is used to fix the second limiting component 211, thus achieving stable installation of the second limiting component 211.

[0032] Furthermore, a cylinder 125 is fixedly installed in the middle of the fixed frame 122. The output end of the cylinder 125 is fixedly connected to the back of the translation plate 120. The cylinder 125 is used to control the movement of the translation plate 120, so that the slider 124 slides on the I-shaped track 123.

[0033] Working principle: When using this device, first ensure the water supply to the nozzle 110, place the device next to the air-cooled island so that the nozzle 110 faces the air-cooled island fins, and the motor 115 controls the rotating disk 113 to rotate. The convex strip 114 on the rotating disk 113 causes the control component 116 to move around the axis. Under the action of the toothed component 117, the gear 118 performs forward and reverse motion, thereby driving the nozzle 110 to swing up and down. As a result, the longitudinal position of the nozzle 110 spraying water toward the air-cooled island fins is changed, and the rinsing effect is better. This solves the problem that the nozzle 110 of the existing device cannot swing up and down, and the rinsing effect needs to be improved. The sealing cap 126 is used to seal the port of the nozzle 110. When using this device, the sealing cap 126 is opened, the water supply pipe is connected to the port of the nozzle 110, and water is supplied to the nozzle 110. Water is sprayed onto the air-cooled island fins through the nozzle 119 to achieve rinsing. The first bolt 121 is used to fix the moving plate 111 to the translation plate 120, realizing the stable fixation of the moving plate 111. The first limiting member 210 and the second limiting member 211 are used to fix the nozzle 110. When the nozzle 110 needs to be replaced, the first limiting part 210 and the second limiting part 211 can be separated for replacement. The second bolt 212 is used to fix the second limiting part 211, which realizes the stable installation of the second limiting part 211. The I-shaped track 123 and the sliding part 124 enable the translation plate 120 to move horizontally on the fixed frame 122, so that the nozzle 110 sprays water to other positions of the air-cooled island fins. The cylinder 125 is used to control the movement of the translation plate 120, so that the sliding part 124 slides on the I-shaped track 123.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
