Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and specifically to a spraying mechanism for a cooling tower. Background Technology

[0002] The spray mechanism of a cooling tower is a core component that uses a spray pump, pipes, and nozzles to pressurize circulating water and spray it evenly onto heat dissipation components (such as packing and coils) to achieve heat exchange between water and air.

[0003] Existing cooling tower spray mechanisms often employ fixed connection structures for their spray components, such as welding or multiple sets of bolts. When spray pipes experience blockages, wear, or other malfunctions requiring repair or replacement, numerous connecting parts must be dismantled. This cumbersome process not only consumes significant manpower and time but may also damage adjacent components due to improper handling during disassembly and assembly, leading to extended cooling tower downtime maintenance cycles and impacting the continuous operation of the overall cooling system. Furthermore, traditional cooling tower spray mechanisms generally lack effective water pretreatment mechanisms. The circulating or makeup water entering the spray system often contains impurities such as silt, scale, and microbial flocs. These impurities easily adhere to and accumulate on the inner walls of the spray pipes, especially causing blockages in narrow channels such as spray holes. This results in reduced spray flow and unstable spray pressure, thereby disrupting spray uniformity and lowering the heat exchange efficiency between the cooling tower and the air. Summary of the Invention

[0004] In view of the problems existing in the spray mechanism of the current cooling tower, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a spraying mechanism for a cooling tower, which solves the problems of cumbersome disassembly and maintenance caused by the fixed connection of spraying components in traditional cooling tower spraying mechanisms, and the lack of effective water pretreatment leading to impurities clogging the spraying pipes and affecting the spraying effect and heat exchange efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A spraying mechanism for a cooling tower includes a spraying assembly. The spraying assembly includes a support chamber. A connecting pipe is rotatably connected to the top of the support chamber. Threaded connecting pipes are fixedly connected to the four sides of the connecting pipe wall. An arc-shaped spraying pipe is threaded into the cavity of each threaded connecting pipe. A locking mechanism is provided between each arc-shaped spraying pipe and the threaded connecting pipe. An inner sealing connection chamber is fixedly connected to the bottom of the cavity of the support chamber. The bottom of the connecting pipe is rotatably connected to the inner sealing connection chamber. A drive mechanism is fixedly connected to the bottom wall of the connecting pipe inside the cavity of the support chamber. An L-shaped water supply pipe is fixedly connected to the bottom of the support chamber. A threaded joint is rotatably connected to one end of the L-shaped water supply pipe.

A water inlet connection flange is fixedly connected to the top of the filter chamber. A drain port is opened at the bottom of the filter chamber and a drain valve is fixedly connected to it. A filter element assembly is snapped between the filter chamber and the filter threaded cover.

[0007] Preferably, the locking mechanism includes a limiting hole, a connecting chamber, a limiting rod, a spring, an adjusting groove, and an adjusting paddle. Each of the arc-shaped spray pipes has a limiting hole on one side wall. Each of the threaded connecting pipes has a connecting chamber fixedly connected to the top of its wall. A limiting rod is slidably connected inside the cavity of each connecting chamber. A spring is sleeved on the wall of each limiting rod. One end of each limiting rod is inserted into the corresponding limiting hole. Each connecting chamber has an adjusting groove on its side wall and an adjusting paddle is slidably connected thereto. The side wall of each adjusting paddle is fixedly connected to the wall of the corresponding limiting rod.

[0008] Preferably, the driving mechanism includes a motor, a drive gear, and a gear ring. The motor is fixedly connected to the inner sidewall of the support chamber. The drive gear is fixedly connected to one end of the motor. The gear ring is fixedly connected to the bottom wall of the connecting pipe. The gear ring and the drive gear are meshed together.

[0009] Preferably, each of the arc-shaped spray pipes is an arc-shaped hollow pipe, and the pipe wall has multiple fan-shaped spray holes.

[0010] Furthermore, the filter element assembly includes a sealed support frame, and a nylon filter layer, an activated carbon adsorption layer, and a PP cotton filter layer are fixedly connected sequentially from the outside to the inside of the cavity of the sealed support frame.

[0011] Preferably, the inner walls of the arc-shaped spray pipe, connecting pipe, threaded connecting pipe and L-shaped water supply pipe are all provided with a ceramic-reinforced epoxy resin coating with a thickness of 25-35μm.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] This utility model discloses a spray mechanism for a cooling tower.

[0020] This utility model provides, for example Figure 1-4 The spraying mechanism of a cooling tower shown includes a spraying assembly 1, which includes a support chamber 2. A connecting pipe 3 is rotatably connected to the top of the support chamber 2. Threaded connecting pipes 4 are fixedly connected to the four sides of the pipe wall of the connecting pipe 3. An arc-shaped spraying pipe 5 is threadedly connected to the cavity of each threaded connecting pipe 4. A locking mechanism is provided between each arc-shaped spraying pipe 5 and the threaded connecting pipe 4. An inner sealing connection chamber 6 is fixedly connected to the bottom of the cavity of the support chamber 2. The bottom of the connecting pipe 3 is rotatably connected to the inner sealing connection chamber 6. A drive mechanism is fixedly connected to the bottom wall of the connecting pipe 3 inside the cavity of the support chamber 2. An L-shaped water supply pipe 7 is fixedly connected to the bottom of the support chamber 2. A threaded connector 8 is rotatably connected to one end of the L-shaped water supply pipe 7. A filter threaded cover 9 is threadedly connected to one end of the threaded connector 8. A filter chamber 10 is threadedly connected to one end of the filter threaded cover 9. A water inlet connection flange 11 is fixedly connected to the top of the filter chamber 10. A drain port 12 is opened at the bottom of the filter chamber 10 and a drain valve 13 is fixedly connected thereto. A filter element assembly 14 is snapped between the filter chamber 10 and the filter threaded cover 9. The spray assembly 1 integrates spraying, driving, and... The filtration function enables integrated operation of the cooling tower water spray, ensuring a continuous spraying process. The support chamber 2 provides installation and protection space for the connecting pipe 3 and drive mechanism, isolating them from external dust and impurities to ensure stable operation of internal components. The connecting pipe 3 serves as the main water delivery channel and also provides installation support for the threaded connecting pipe 4, ensuring the even distribution of multiple sets of arc-shaped spray pipes 5. The threaded connection between the threaded connecting pipe 4 and the arc-shaped spray pipes 5 allows for quick assembly and disassembly of the spray pipes, facilitating future maintenance and replacement. The arc-shaped structure of the arc-shaped spray pipes 5 expands the spray coverage area and improves the uniformity of water distribution within the cooling tower. A locking mechanism further secures the arc-shaped spray pipes 5 to the threaded connecting pipe. The relative positions of 4 prevent the spray pipe from loosening due to water pressure impact during spraying, ensuring stable spraying. The inner sealing connection chamber 6 ensures that water does not leak when the connecting pipe 3 rotates, keeping the cavity of the support chamber 2 dry and preventing damage to the drive mechanism from moisture. The drive mechanism drives the connecting pipe 3 and the arc-shaped spray pipe 5 to rotate, forming a rotating coverage of sprayed water, further expanding the spray range and improving heat exchange efficiency. The L-shaped water supply pipe 7 delivers water between the support chamber 2 and the filter chamber 10, adapting to the cooling tower piping layout. The threaded connector 8 facilitates quick connection between the L-shaped water supply pipe 7 and the filter threaded cover 9, simplifying the assembly process. The filter threaded cover 9 provides an installation and fixing structure for the filter element assembly 14, while also facilitating disassembly. The filter element is replaced, and the filter chamber 10 provides filtration space for the filter element assembly 14, ensuring sufficient water pretreatment. The inlet connection flange 11 facilitates the connection between the filter chamber 10 and the cooling tower inlet pipe, improving installation compatibility. The drain port 12, in conjunction with the drain valve 13, can periodically discharge impurities deposited in the filter chamber 10, preventing impurity accumulation from affecting the filtration effect. The filter element assembly 14 performs multi-stage filtration on the water entering the spray mechanism, removing impurities and odors, and preventing spray pipe blockage. This solves the problems of traditional cooling tower spray mechanisms, which are cumbersome to disassemble and maintain due to the fixed connection of the spray components, and the lack of effective water pretreatment that causes impurities to clog the spray pipes, affecting the spray effect and heat exchange efficiency.

[0021] To quickly secure the curved sprinkler pipe to the threaded connection pipe and improve ease of assembly and disassembly, such as Figure 1 , 3 As shown in Figure 4, the locking mechanism includes a limiting hole 15, a connecting chamber 16, a limiting rod 17, a spring 18, an adjusting groove 19, and an adjusting lever 20. Each arc-shaped spray pipe 5 has a limiting hole 15 on one side wall. Each threaded connecting pipe 4 has a connecting chamber 16 fixedly connected to its top wall. A limiting rod 17 is slidably connected inside the cavity of the connecting chamber 16. A spring 18 is sleeved on the wall of each limiting rod 17. One end of each limiting rod 17 is inserted into the corresponding limiting hole 15. Each connecting chamber 16 has an adjusting groove 19 on its side wall, and an adjusting lever 20 is slidably connected thereto. The side wall of each adjusting lever 20 is fixedly connected to the wall of the corresponding limiting rod 17. The limiting hole 15 provides an insertion and positioning point for the limiting rod 17, achieving mechanical limiting. To improve the stability of the connection between the arc-shaped spray pipe 5 and the threaded connecting pipe 4, the connecting compartment 16 provides installation space for the limiting rod 17 and the spring 18, ensuring the stability of the locking mechanism. The limiting rod 17 is inserted into the limiting hole 15, directly restricting the rotation of the arc-shaped spray pipe 5 and preventing the threaded connection from loosening. The spring 18 pushes the limiting rod 17 to always remain in the insertion state with the limiting hole 15 through elastic deformation, eliminating the need for additional locking operations. The adjusting groove 19 provides a sliding trajectory for the adjusting lever 20, ensuring that the lever drives the rod to move accurately. The adjusting lever 20 increases the contact area between the hand and the limiting rod 17, making it easier for operators to quickly control the raising and lowering of the rod, achieving locking and unlocking, and greatly improving the efficiency of spray pipe assembly and disassembly.

[0022] To drive the connecting pipe and the arc-shaped spray pipe to rotate, thereby expanding the spray coverage area, such as Figure 3 As shown, the drive mechanism includes a motor 21, a drive gear 22, and a gear ring 23. The motor 21 is fixedly connected to the inner side wall of the support chamber 2, and the drive gear 22 is fixedly connected to one end of the motor 21. The gear ring 23 is fixedly connected to the bottom wall of the connecting pipe 3. The gear ring 23 and the drive gear 22 are meshed together. The motor 21 provides a continuous and stable rotational driving force, and the speed can be adjusted to adapt to different spraying needs. The drive gear 22 and the gear ring 23 mesh together to transmit power, resulting in high transmission efficiency and low noise, ensuring that the connecting pipe 3 rotates at a uniform speed. The gear ring 23 is arranged around the connecting pipe 3 to ensure that the driving force is evenly transmitted to the connecting pipe 3, avoiding eccentric rotation of the connecting pipe due to uneven force, and ensuring spraying stability. At the same time, the rotating spray can make the water evenly distributed in the cooling tower, improving the heat exchange efficiency.

[0023] To improve the atomization effect and uniformity of the sprayed water, such as Figure 1 and 3As shown, each arc-shaped spray pipe 5 is an arc-shaped hollow pipe, and the pipe wall has multiple fan-shaped spray holes 24. The arc-shaped hollow pipe structure allows the arc-shaped spray pipe 5 to be adapted to the circumferential distribution of the connecting pipe 3, while expanding the spray coverage angle of a single spray pipe. The multiple fan-shaped spray holes 24 are evenly distributed along the pipe wall of the arc-shaped spray pipe 5 to ensure that the spray water is covered without dead corners, and to avoid uneven heat exchange caused by local water shortage in the cooling tower.

[0024] To achieve multi-stage water filtration and prevent impurities from clogging the spray pipes, such as Figure 2 As shown, the filter element assembly 14 includes a sealed support frame 25. A nylon filter mesh layer 26, an activated carbon adsorption layer 27, and a PP cotton filter layer 28 are sequentially fixedly connected inside the cavity of the sealed support frame 25 from the outside to the inside. The sealed support frame 25 provides structural support for each filter layer and ensures a sealed fit between the filter element assembly and the filter chamber 10, preventing unfiltered water from directly flowing into the spray pipe. The nylon filter mesh layer 26 first filters large particles (such as silt and debris) from the water to prevent clogging of subsequent filter layers. The activated carbon adsorption layer 27 adsorbs odors and organic matter from the water, improving the cleanliness of the sprayed water. The PP cotton filter layer 28 further filters small impurities (such as suspended solids). This triple filtration ensures that the water entering the spray pipe is free of impurities, completely solving the problem of spray pipe clogging.

[0025] To improve the corrosion resistance and wear resistance of the various pipelines in the spraying system and extend their service life, such as... Figure 1-4 As shown, the inner walls of the arc-shaped spray pipe 5, connecting pipe 3, threaded connecting pipe 4, and L-shaped water supply pipe 7 are all coated with ceramic-reinforced epoxy resin with a thickness of 25-35μm. The ceramic-reinforced epoxy resin coating has excellent corrosion resistance, which can resist the corrosion of the pipes by chloride ions, microorganisms, etc. in the cooling tower water, and prevent the pipes from rusting or perforating. The coating also has high hardness, which can reduce the wear of the inner wall of the pipes caused by water flow and impurities. The coating thickness of 25-35μm balances the protective effect and the flow area of ​​the pipes, avoiding the reduction of the inner diameter of the pipes due to excessive coating thickness, which affects the water flow and ensures the long-term stable operation of the spray mechanism.

[0026] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
