Description

Technical Field

[0001] This utility model relates to the field of dust prevention technology for spray pipes, specifically a dust prevention component for spray pipes. Background Technology

[0002] In industrial production, large-scale refrigeration systems, and some special processes, condensers play a crucial role as key equipment for heat exchange. They transfer the heat from high-temperature gas or steam to the cooling medium, causing the gas or steam to condense into liquid, thereby maintaining the stable operation of the entire system. Spray pipes, as an important component of the condenser cooling system, can effectively enhance the condensation effect, improve heat exchange efficiency, and ensure that the condenser operates under optimal conditions by spraying cooling water onto the condenser surface. However, in the actual application of condenser spray pipes, the problem of nozzles being easily contaminated by dust and debris has become increasingly prominent, seriously affecting the performance of the spray system and the operating efficiency of the condenser. Currently, condensers are usually installed outdoors or in relatively open environments such as industrial plants, where the surrounding air often contains a large amount of dust, sand, fluff, metal shavings, and other impurities. When the spray pipe is not in a spraying state, the nozzles are directly exposed to the external environment, and these impurities easily adhere to the nozzle surface and gradually enter the nozzle interior, causing accumulation in the nozzles, flow channels, and other parts of the nozzle, narrowing or even completely blocking the water flow channels. Once the nozzles are blocked, the spray pipe cannot spray cooling water onto the condenser surface normally, resulting in uneven cooling of the condenser surface and excessively high local temperatures. This not only reduces the heat exchange efficiency of the condenser and increases energy consumption, but also affects the normal operation of the entire system and may even lead to equipment failure and shutdown.

[0003] Therefore, we propose a dustproof component for spray pipes to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a dustproof component for spray pipes, which solves the problems mentioned in the background section.

[0005] The objective of this utility model can be achieved through the following technical solutions: A dustproof assembly for a spray pipe includes a water inlet pipe. Spray nozzles are fixedly connected at equal intervals to the lower outer surface of the water inlet pipe. Fixing plates are symmetrically fixedly connected to the outer surface of the water inlet pipe. Each fixing plate has a through groove. A slider is slidably connected to each through groove. A connecting post is fixedly connected to the lower end of each slider. A movable frame is fixedly connected between the lower ends of two connecting posts. Dustproof plates are fixedly connected at equal intervals to the movable frame. The dustproof plates are all offset from the spray nozzles, and the number of dustproof plates is the same as the number of spray nozzles.

[0006] As a further embodiment of this utility model: a hollow column is fixedly connected to the outer surface of the water inlet pipe, the hollow column is connected to the water inlet pipe, an extension column is slidably connected to the end of the hollow column away from the water inlet pipe, a fixing block is fixedly connected to the end of the extension column away from the hollow column, a connecting plate is rotatably connected to the side of the fixing block near the moving frame, a connecting block is rotatably connected to the end of the connecting plate away from the fixing block, and the connecting block is fixedly connected to the side wall of the moving frame.

[0007] As a further embodiment of this utility model: a rubber sealing plate is fixedly connected to one end of the extension column inside the hollow column. The rubber sealing plate is slidably disposed inside the hollow column, and the outer peripheral wall of the rubber sealing plate forms a sliding sealing fit with the inner wall of the hollow column.

[0008] As a further embodiment of this utility model: a spring is fixedly connected to one end of the fixing block near the hollow column, and the other end of the spring away from the fixing block is fixedly connected to the lower end of the hollow column, and the spring is sleeved on the outer surface of the extension column.

[0009] As a further embodiment of this utility model: each side of the dustproof plate is fixedly connected to a mounting bracket, and each mounting bracket is fixedly connected to a cleaning plate on its upper end face, the number of cleaning plates being the same as the number of nozzles.

[0010] The beneficial effects of this utility model are: By incorporating hollow columns, extension columns, fixing blocks, springs, connecting plates, connecting blocks, moving frames, connecting columns, fixing plates, through slots, and sliders, the dustproof plate automatically moves out when the nozzle is spraying water, ensuring the nozzle works normally. After spraying, the dustproof plate automatically covers the nozzle, effectively preventing dust and debris from entering the nozzle and avoiding clogging, thus extending the nozzle's lifespan and reducing maintenance costs. By utilizing the pressure changes in the water flow during spraying or stopping, the dustproof plate can be automatically driven to perform corresponding actions, eliminating the need for additional manual operation or complex electrical control systems, achieving automated control of the dustproof plate.

[0011] The rubber sealing plate improves the sealing between the hollow column and the extension column, effectively preventing water leakage from the gap between them. As water flows into the hollow column and pushes the rubber sealing plate to slide, the good sealing ensures that the water pressure can fully act on the rubber sealing plate, thereby stably pushing the extension column out, moving the fixed block, and enabling the subsequent dustproof plate and other components to move, ensuring the smooth operation of the entire drive process.

[0012] 2. The mounting bracket and cleaning plate allow the cleaning plate to wipe and clean the surface of the nozzle before the protective plate covers or is removed from the nozzle. This removes dust, scale, and other dirt from the nozzle surface, ensuring the spraying effect and preventing the accumulation of dirt on the nozzle surface from affecting the direction and range of water flow, thereby improving the spraying effect.

[0015] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0016] like Figures 1-4 As shown, a dustproof assembly for a spray pipe includes a water inlet pipe 1. Spray nozzles 2 are fixedly connected at equal intervals below the outer surface of the water inlet pipe 1. Fixing plates 5 are symmetrically fixedly connected to the outer surface of the water inlet pipe 1. Each fixing plate 5 has a through groove 6. A slider 7 is slidably connected in each through groove 6. A connecting post 4 is fixedly connected to the lower end of each slider 7. A movable frame 3 is fixedly connected between the lower ends of two connecting posts 4. Dustproof plates 8 are fixedly connected at equal intervals on the movable frame 3. The dustproof plates 8 are all offset from the spray nozzles 2, and the number of dustproof plates 8 and spray nozzles 2 is the same.

[0017] In this embodiment, as Figure 2As shown, a hollow column 9 is fixedly connected to the outer surface of the water inlet pipe 1. The hollow column 9 is connected to the water inlet pipe 1. An extension column 16 is slidably connected to the end of the hollow column 9 away from the water inlet pipe 1. A fixing block 12 is fixedly connected to the end of the extension column 16 away from the hollow column 9. A connecting plate 13 is rotatably connected to the side of the fixing block 12 near the moving frame 3. A connecting block 14 is rotatably connected to the end of the connecting plate 13 away from the fixing block 12. The connecting block 14 is fixedly connected to the side wall of the moving frame 3. When water flows into the hollow column 9, it will push the extension column 16 to slide out from the hollow column 9. Through the fixing block 12, the connecting plate 13 and the connecting block 14, the moving frame 3 will be pulled to move horizontally.

[0018] In this embodiment, as Figure 4 As shown, an extension column 16 is fixedly connected to a rubber sealing plate 17 at one end inside the hollow column 9. The rubber sealing plate 17 is slidably disposed inside the hollow column 9, and the outer peripheral wall of the rubber sealing plate 17 forms a sliding seal with the inner wall of the hollow column 9. When the extension column 16 slides out of the hollow column 9 due to the impact of water flow, the rubber sealing plate 17 can improve the sealing between the extension column 16 and the hollow column 9, preventing water from flowing out of the hollow column 9.

[0019] In this embodiment, as Figure 2 As shown, a spring 15 is fixedly connected to one end of the fixing block 12 near the hollow column 9, and the other end of the spring 15 away from the fixing block 12 is fixedly connected to the lower end of the hollow column 9. The spring 15 is sleeved on the outer surface of the extension column 16. When the extension column 16 is subjected to force and slides out from the inside of the hollow column 9, pushing the fixing block 12 away from the hollow column 9, it will simultaneously pull the spring 15 between the fixing block 12 and the hollow column 9. When the force on the extension column 16 disappears, the rebound force of the spring 15 can pull the fixing block 12 closer to the hollow column 9 and push the extension column 16 to slide into the hollow column 9.

[0020] In this embodiment, as Figure 2 As shown, a mounting bracket 10 is fixedly connected to one side of the dustproof plate 8, and a cleaning plate 11 is fixedly connected to the upper surface of the mounting bracket 10. The number of cleaning plates 11 is the same as that of the nozzle 2. During the movement of the dustproof plate 8, the cleaning plate 11 can be moved synchronously by the mounting bracket 10, so that the cleaning plate 11 can wipe and clean the surface of the nozzle 2.

[0021] The effects achieved by this embodiment are as follows: In the existing technology, during the actual application of condenser spray pipes, the problem of nozzles 2 being easily contaminated by dust and debris is becoming increasingly prominent, seriously affecting the performance of the spray system and the operating efficiency of the condenser. Currently, condensers are usually installed outdoors or in relatively open environments such as industrial plants, where the surrounding air often contains a large amount of dust, sand, fluff, metal shavings, and other impurities. When the spray pipe is not in a spraying state, the nozzles 2 are directly exposed to the external environment. These impurities easily adhere to the surface of the nozzles 2 and gradually enter the interior of the nozzles 2, causing accumulation in the nozzles, flow channels, and other parts of the nozzles 2, narrowing or even completely blocking the water flow channels. Once the nozzles 2 are blocked, the spray pipe cannot spray cooling water onto the condenser surface normally, leading to condenser... Uneven surface cooling and excessively high local temperatures not only reduce the heat exchange efficiency of the condenser and increase energy consumption, but also affect the normal operation of the entire system and may even lead to equipment failure and shutdown. Compared with existing technologies, when the nozzle 2 sprays water, the dustproof plate 8 can be automatically moved out to ensure the normal operation of the nozzle 2. After spraying, the dustproof plate 8 can be automatically covered on the nozzle 2 to effectively prevent dust, debris and other objects from entering the nozzle 2 and avoid clogging, thereby extending the service life of the nozzle 2 and reducing maintenance costs. By utilizing the pressure changes of the water flow during the spraying or stopping process, the dustproof plate 8 can be automatically driven to perform corresponding actions without additional manual operation or complex electrical control systems, realizing the automated control of the dustproof plate 8.

[0022] The overall working process and principles involved in the above embodiments are as follows: During the water flow process inside the inlet pipe 1, the water flow enters the hollow column 9. As the water flow inside the hollow column 9 increases, the water flow pushes the rubber sealing plate 17 to slide inside the hollow column 9, and drives the extension column 16 to slide out from inside the hollow column 9. At this time, during the sliding process of the extension column 16, the extension column 16 will push the fixing block 12 away from the hollow column 9, and at the same time pull the spring 15 connected between the fixing block 12 and the hollow column 9. Since the connecting block 14 is rotatably connected to the side wall of the connecting block 14, and the connecting block 14 is fixedly connected to the side wall of the moving frame 3, during the descent of the fixing block 12, the connecting plate 13 and the connecting block 14 can pull one side of the moving frame 3 to move towards the hollow column 9. Since the upper end of the moving frame 3 is symmetrically fixed... A connecting column 4 is connected, and a slider 7 is fixedly connected to the upper end of the connecting column 4. The slider 7 is slidably connected in the through groove 6 opened on the fixed plate 5. Therefore, when one end of the moving frame 3 is pulled, the moving frame 3 can be moved horizontally through the connecting column 4, slider 7 and through groove 6, which drives the protective plate connected to the moving frame 3 to move out from directly below the nozzle 2, so that the nozzle 2 unfolds and sprays water. At the same time, the cleaning plate 11 connected to the side wall of the nozzle 2 passes under the nozzle 2 to clean the nozzle 2, and remove the dust, scale and other dirt attached to the surface of the nozzle 2 in time, so as to ensure the spraying effect of the nozzle 2, thereby avoiding the situation that the spraying direction and spraying range are affected by the accumulation of dirt on the surface of the nozzle 2, and thus improving the spraying effect. After the spraying of nozzle 2 ends, the water flow inside the inlet pipe 1 will be stopped. At this time, the impact force of the water flow on the rubber sealing plate 17 inside the hollow column 9 will be reduced. Then, through the rebound force of the spring 15 connected between the fixed block 12 and the hollow column 9, the fixed block 12 can be automatically pulled to rise and approach the hollow column 9. As the fixed block 12 rises, the fixed block 12 will pull the connecting plate 13 and the connecting block 14, pushing the moving frame 3 to move in the opposite direction again. This allows the cleaning plate 11 connected to the moving frame 3 to wipe the area sprayed by nozzle 2 first, and then drive the dustproof plate 8 to cover the nozzle 2. This effectively prevents dust, debris and other objects from entering the interior of nozzle 2, avoiding clogging of nozzle 2, thereby extending the service life of nozzle 2 and reducing maintenance costs. By utilizing the pressure change of the water flow during the spraying or stopping process, the dustproof plate 8 can be automatically driven to perform corresponding actions without additional manual operation or complex electrical control systems, realizing the automated control of the dustproof plate 8.
