Description

Technical Field

[0001] This utility model relates to the technical field of flow water distribution mechanisms, specifically a variable flow water distribution mechanism for cooling towers. Background Technology

[0002] Cooling towers are widely used heat exchange equipment in industrial and civil fields. Their core function is to dissipate the heat of circulating cooling water into the atmosphere through the contact between water and air, thereby reducing the water temperature and ensuring the stable operation of various heat exchange systems.

[0003] With the increasing demands for energy conservation and intelligent control in modern industry and construction, variable flow cooling towers are being used more and more widely. Variable flow cooling towers can dynamically adjust the water flow entering the cooling tower according to changes in actual heat load, thereby achieving energy conservation, consumption reduction, and optimized operation. Currently, various variable flow water distribution schemes exist in existing technologies. A utility model patent with publication number CN223021060U discloses a variable flow water distribution mechanism for cooling towers. This mechanism includes a cooling tower body with a vertical metal pipe installed inside. The top of the pipe is connected to a cross-shaped connecting steel pipe, and the ends of the connecting steel pipe are connected to a spray frame. Electromagnetic valves are installed in all four directions of the connecting steel pipe. Temperature sensors are installed inside the cooling tower body to detect the temperature at different locations, and then the electromagnetic valves adjust the water flow of the corresponding spray frame. However, existing technologies still have significant shortcomings in terms of the intuitiveness of water level monitoring. The metal pipes in existing technologies are usually installed inside the cooling tower, but in actual operation, when it is necessary to adjust the water level to adapt to different flow rate changes, it is difficult for operators to observe the water level in the liquid level pipe in a timely and accurate manner. Because it is impossible to obtain water level information directly and in real time, operators often have to rely on experience or indirect methods to judge whether the water level is appropriate. This not only increases the difficulty and uncertainty of operation, but also easily leads to uneven water distribution. When the water level is not properly adjusted, it may result in insufficient nozzle pressure or overflow, or even uneven wetting of the packing layer, affecting the heat exchange efficiency.

[0004] Therefore, this utility model provides a variable flow water distribution mechanism for cooling towers to solve the above problems. Utility Model Content

[0005] This invention provides a variable flow water distribution mechanism for cooling towers, aiming to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A variable flow water distribution mechanism for a cooling tower includes a level pipe, the bottom end of which is connected to a distribution pipe. The distribution pipe is horizontally arranged, and multiple sets of liquid distribution pipes are connected to both sides of the distribution pipe. The bottom ends of the multiple sets of liquid distribution pipes are connected to multiple sets of nozzles for uniformly spraying water onto the cooling tower packing layer. A fixing plate is fixedly installed on the bottom end of the inner wall of the level pipe, and a connecting rope is fixedly connected to the top end of the fixing plate. A plastic floating block is fixedly connected to the end of the connecting rope, and magnetic suction plates are fixedly installed on both sides of the plastic floating block. Flip-plate assemblies are provided on the outer surfaces of both sides of the level pipe, and the flip-plate assemblies are used to indicate the water level position according to the water level change in the level pipe.

[0007] As a preferred technical solution of this application, the flap assembly includes two sets of limiting plates fixedly installed on the outer walls of both sides of the liquid level tube. A long rod is rotatably installed between the two sets of limiting plates through multiple sets of bearing rings evenly distributed in the vertical direction. The long rod is set perpendicular to the outer wall of the liquid level tube, and multiple sets of flaps are evenly fixedly installed on the outer surface of the long rod along its length direction. The flaps can flip as the long rod rotates to indicate different water level heights.

[0008] As a preferred technical solution of this application, a connecting plate is fixedly installed at the top of the liquid level tube, and multiple sets of screw holes are opened on the connecting plate.

[0009] As a preferred technical solution of this application, the inner wall of the liquid level tube is provided with grooves on both sides, and a magnetic suction plate is slidably installed in the grooves.

[0010] As a preferred technical solution of this application, a flange is fixedly installed at the top end of the liquid level pipe, and the flange is used to connect an external pipe.

[0011] As a preferred technical solution of this application, each of the multiple sets of liquid distribution pipes is fixedly installed with a fixing ring, and a fixing rod is fixedly installed between the fixing rings.

[0012] The reliable connection between the flange and the external water pipe ensures a stable water flow. The water flows through the level pipe, distribution pipe, and liquid distribution pipe to the nozzle for even spraying, fully covering the packing layer and greatly improving heat exchange efficiency. At the same time, the plastic floating block inside the level pipe floats with the water level, causing the magnetic plate to slide, which in turn causes the long rod in the flap assembly to rotate and the flap to flip, intuitively indicating the water level. Operators can then accurately adjust the water level accordingly, ensuring the stable and efficient operation of the cooling tower's variable flow water distribution mechanism and improving the overall performance of the cooling tower.

Detailed Implementation

[0015] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides a variable flow water distribution mechanism for cooling towers, such as... Figures 1-5 As shown, the system includes a level pipe 1, which serves as the initial container for water flow, storing and initially stabilizing the water level. A distribution pipe 2 is connected to the bottom of the level pipe 1. The distribution pipe 2 is horizontally positioned, and multiple sets of distribution pipes 3 are connected to both sides of the distribution pipe 2. The distribution pipes 3 further guide the water flow to different positions. Multiple sets of nozzles 31 are connected to the bottom of the multiple distribution pipes 3 to evenly spray the water flow onto the cooling tower packing layer. A fixing plate 71 is fixedly installed at the bottom of the inner wall of the level pipe 1, and a connecting rope 7 is fixedly connected to the top of the fixing plate 71. A plastic floating block 8 is fixedly connected to the end of the connecting rope 7, and magnetic plates 81 are fixedly installed on both sides of the plastic floating block 8. The floating of the plastic floating block 8 can reflect the water level in the level pipe 1 in real time. The combination of the connecting rope 7 and the fixing plate 71 ensures the stability and accuracy of the floating of the plastic floating block 8. Flip-plate assemblies are provided on the outer surfaces of both sides of the level pipe 1. The flip-plate assemblies are used to indicate the water level position based on changes in the water level inside the level pipe 1.

[0017] The flap assembly includes two sets of limiting plates 9 fixedly installed on the outer walls of both sides of the liquid level pipe 1. The limiting plates 9 provide the installation position and rotation limit for the long rod 92. The long rod 92 is rotatably installed between the two sets of limiting plates 9 through multiple sets of bearing rings 91 evenly distributed in the vertical direction. The long rod 92 is set perpendicular to the outer wall of the liquid level pipe 1, and multiple sets of flaps 93 are evenly fixedly installed on the outer surface of the long rod 92 along its length direction. The bearing rings 91 ensure that the long rod 92 can rotate smoothly. The long rod 92 serves as the support and rotation axis of the flaps 93. The flaps 93 indicate the water level height by flipping. The flaps 93 can flip as the long rod 92 rotates to indicate different water level heights.

[0018] The liquid level pipe 1 is fixedly installed with a connecting plate 5, and the connecting plate 5 has multiple sets of screw holes. Through the design of the connecting plate 5 and the screw holes, the liquid level pipe 1 can be conveniently and firmly installed on the cooling tower, and can be installed externally to ensure the stability of the entire variable flow water distribution mechanism and avoid affecting its normal operation due to shaking or displacement.

[0019] The inner wall of the liquid level pipe 1 has grooves 11 on both sides, and a magnetic suction plate 81 is slidably installed in the grooves 11. The grooves 11 provide a sliding track for the magnetic suction plate 81, which restricts the movement direction of the magnetic suction plate 81, so that it can only slide in the vertical direction.

[0020] The top of the liquid level pipe 1 is fixedly equipped with a flange 6, which is used to connect to an external pipe to ensure that water can flow smoothly and stably into the liquid level pipe 1, while facilitating installation, disassembly and maintenance.

[0021] Each of the multiple sets of liquid distribution pipes 3 is fixedly installed with a fixing ring 4, and a fixing rod 41 is fixedly installed between the fixing rings 4. This enhances the structural stability between the multiple sets of liquid distribution pipes 3, prevents the liquid distribution pipes 3 from shaking, deforming or shifting under the impact of water flow or external factors, ensures that the water flow can be evenly distributed and sprayed according to the design requirements, and improves the reliability and service life of the entire variable flow water distribution mechanism.

[0022] Working principle: First, the flange 6 fixedly installed at the top of the liquid level pipe 1 is reliably connected to the external water pipe. After the water source is turned on, the water flows into the liquid level pipe 1 through the external pipe. As the water continues to flow in, the water level in the liquid level pipe 1 gradually rises. When the water level reaches a certain height, the water will flow from the bottom of the liquid level pipe 1 into the distribution pipe 2 connected to it. Since the distribution pipe 2 is set horizontally, the water flow is evenly distributed in the distribution pipe 2 and flows into the multiple sets of liquid distribution pipes 3 connected on both sides of the distribution pipe 2. The multiple sets of liquid distribution pipes 3 further guide the water flow to the multiple sets of nozzles 31 connected at their bottom ends, and finally spray it out evenly through the multiple sets of nozzles 31, so that the water flow can fully cover the packing layer of the cooling tower and achieve efficient heat exchange. During the process of water level change in the liquid level tube 1, the connecting rope 7, which is fixedly installed at the top of the fixing plate 71 at the bottom of the inner wall of the liquid level tube 1, will change its state accordingly with the change of water level. The density of the plastic floating block 8 is less than that of water, so it will float up and down with the rise and fall of the water level in the liquid level tube 1. When the plastic floating block 8 floats up and down, the magnetic suction plates 81 fixed on both sides slide in the grooves 11 opened on both sides of the inner wall of the liquid level pipe 1. Since the magnetic suction plates 81 and the long rods 92 set in the flap assembly on both sides of the outer surface of the liquid level pipe 1 have a magnetic attraction, when the magnetic suction plates 81 slide in the grooves 11, they will drive the long rods 92 to rotate around their own axis. As the long rods 92 rotate, multiple flaps 93 will flip accordingly. Different water levels will cause the plastic floating block 8 to be in different positions, which will drive the long rods 92 to rotate to different angles, so that the flaps 93 will flip to different states. This will intuitively indicate the different water level heights in the liquid level pipe 1, remind people of the current water level, and make it convenient for operators to adjust and control the water level according to actual needs, ensuring the stable and efficient operation of the cooling tower variable flow water distribution mechanism.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
