Description

Technical Field

[0001] This utility model belongs to the field of cooling equipment, specifically relating to a cooling tower balanced water distribution system. Background Technology

[0002] Due to environmental protection requirements, quarries have begun to use enclosed metal-sheet workshops to completely surround the working environment, so as to prevent the huge dust and noise in the working environment from affecting the surrounding environment. At the same time, this enclosed workshop environment also makes production operations no longer affected by the weather. The operating environment of production facilities is better protected, thus extending their service life. The only drawback is that the operating equipment (such as crushers or screening machines) in the enclosed metal-sheet workshops are prone to high temperatures, and these high-temperature equipment generally require the use of cooling towers for cooling.

[0003] A cooling tower uses water as a circulating coolant. Its cooling mechanism utilizes the heat exchange between water and air to generate steam. The steam evaporates and carries away heat, achieving heat dissipation through evaporation, convection, and radiation. This process dissipates waste heat generated in industrial processes or refrigeration and air conditioning systems, thereby lowering the water temperature and ensuring the normal operation of the system. The device is generally cylindrical, hence the name cooling tower.

[0004] Traditional cooling towers use a spray tray structure such as Figure 1 As shown, a large array of water outlet pipes (holes) of uniform height are evenly installed on the sprinkler tray. The sprinkler tray is relatively shallow. When the water in the sprinkler tray is sufficient, the water flows evenly through the water outlet pipes and onto the radiator below. Figure 1 As shown in Figure A; when the water volume in the sprinkler tray is insufficient, the water volume at the inlets of the cold water pipes on both sides is larger and the drainage is sufficient. However, in the middle section away from the cold water pipes on both sides, the water volume is smaller and the drainage is insufficient, resulting in uneven spraying. Figure 1 As shown in B, this situation results in low heat dissipation efficiency of the radiator and poor energy-saving effect. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a balanced water distribution system for cooling towers, which solves the problems of poor cooling efficiency and ineffective energy saving in cooling towers.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cooling device for a quarry includes a cooling tower body, a water spraying tray installed inside the cooling tower body, a plurality of water outlet pipes fixedly installed inside the water spraying tray, a fixed cylinder fixedly installed on the top of the cooling tower body, a mounting frame fixedly installed on the top of the fixed cylinder, a motor fixedly installed on the top of the mounting frame, and a rotating fan blade mounted on the motor via a rotating shaft at its output end. An N-stage array of water outlet holes with progressively decreasing height at the top is fixedly installed on the bottom wall of the water spraying tray. Spray nozzles are connected to the lower ends of the N-stage array of water outlet holes and are located at the bottom of the water spraying tray. Heat dissipation fins are located below the spray nozzles and are fixedly connected to the inner wall of the cooling tower body on both sides. A water tank is fixedly installed on one side of the surface of the cooling tower body, a water pump is installed on the surface of the water tank, a connecting water pipe is provided at the output end of the water pump, a fixed water pipe is fixedly installed at one end of the connecting water pipe, and a water spraying pipe is fixedly installed on one side of the fixed water pipe, extending into the interior of the cooling tower body.

[0008] Preferably, a total of ten sprinkler pipes are provided, and one end of the sprinkler pipe is positioned above the sprinkler plate.

[0009] Preferably, a water inlet pipe is fixedly installed on one side of the surface of the water tank, and a fixing plate is fixedly installed at one end of the water inlet pipe, with fixing holes provided on the surface of the fixing plate.

[0010] Preferably, a drainage tank is fixedly installed in the middle of the bottom of the cooling tower body, and a drainage pipe is fixedly installed on one side of the surface of the drainage tank. A switch valve is provided on one side of the surface of both the water inlet pipe and the drainage pipe.

[0011] Preferably, support rods are fixedly installed around the bottom of the cooling tower body, and a base plate is fixedly installed at one end of each support rod, with the base plate being hollow in the middle.

[0012] Preferably, a ladder is fixedly installed on one side of the surface of the cooling tower body, and the surface of the ladder is provided with an anti-rust coating.

[0013] Preferably, a protective rod is fixedly installed on the surface of the fixed cylinder, an installation plate is fixedly installed at one end of the protective rod, a fixing groove is provided on the top of the installation plate, and a dustproof net is provided inside the fixing groove.

[0015] Preferably, the N-stage water outlet array includes a first-stage water outlet array, a second-stage water outlet array, and a third-stage water outlet array arranged sequentially from low to high height at the top.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: the water spray plate is equipped with stepped water outlet pipes (water outlet holes), which can more effectively distribute the cooling water evenly on the radiator when the cooling water flow of a single cooling tower is adjusted, making fuller use of the heat dissipation carrier, expanding the heat dissipation area, improving heat dissipation efficiency, and saving more energy; when the water spray plates of multiple cooling towers are horizontally connected, the water distribution method of this new water spray plate can more actively and effectively distribute the cooling water evenly on the heat dissipation fins; at the same time, when used in conjunction with variable frequency cooling water pumps and temperature-controlled cooling tower fans, this new water spray plate has a high input-output ratio, obvious energy-saving effect, and can greatly reduce the working temperature of quarry production equipment.

[0027] 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.

[0028] Please see Figure 2-3 This utility model provides the following technical solution: In an embodiment of the sprinkler plate 23, a first water outlet array 200, a second water outlet array 20, and a second water outlet array 21 are fixedly installed at the bottom of the sprinkler plate 23. The upper height of the third water outlet array 21 is greater than the upper height of the second water outlet array 20, and the upper height of the second water outlet array 20 is greater than the upper height of the first water outlet array 200. Thus, when the water volume is sufficient (100%), the water flow is evenly distributed onto the radiator 24 through the stepped water outlet pipes; when the water volume is insufficient (e.g., ...), ... Figure 3 As shown, the water flow can still be evenly distributed onto the radiator 24 through the stepped water outlet pipe.

[0029] like Figure 4-8An embodiment of a cooling device for a quarry includes a cooling tower body 1. A water spray plate 23 is installed inside the cooling tower body 1. A fixed cylinder 18 is fixedly installed on the top of the cooling tower body 1. A mounting frame 16 is fixedly installed on the top of the fixed cylinder 18. A motor 19 is fixedly installed on the top of the mounting frame 16. The motor 19 has rotating fan blades 17 connected to its output shaft. The water spray plate 23 is fixedly installed inside the cooling tower body 1. A first water outlet array 20 and a second water outlet array 21 are fixedly installed on the bottom of the inner wall of the water spray plate 23, respectively. The upper height of the second water outlet array 21 is greater than that of the first water outlet array 20. At the upper end of column 20, a nozzle 25 is provided at one end of the first water outlet array 20 and the second water outlet array 21. The nozzle 25 is located at the bottom of the water spray plate 23. A heat sink 24 is provided below the nozzle 25. The two sides of the heat sink 24 are fixedly connected to the inner wall of the cooling tower body 1. A water tank 7 is fixedly installed on one side of the surface of the cooling tower body 1. A water pump 5 is provided on the surface of the water tank 7. A connecting water pipe 6 is provided at the output end of the water pump 5. A fixed water pipe 11 is fixedly installed at one end of the connecting water pipe 6. A water spray pipe 22 is fixedly installed on one side of the surface of the fixed water pipe 11 and extends into the interior of the cooling tower body 1.

[0030] First, the water pump 5 is started to draw water from the water tank 7. Then, water is injected into the spray plate 23 through the connecting water pipe 6, the fixed water pipe 11, and the spray pipe 22. When the water level in the spray plate 23 is higher than the first water outlet array 200, the second water outlet array 20, or the third water outlet array 21, water will be sprayed out through the nozzle 25, so that the water is evenly sprayed on the heat sink 24. The heat sink 24 dissipates heat by increasing the surface area. The motor 19 can also be started to drive the rotating fan blade 17 to rotate, thereby expelling the hot air inside the cooling tower body 1, which is conducive to rapid heat dissipation and improves the cooling efficiency of this device. After the hot water is cooled, it can enter the drain tank 15. When there is too much water inside the cooling tower body 1, the switch valve can be opened to allow the water inside the cooling tower body 1 to be discharged through the drain pipe 14. The water inlet pipe 4 can be connected to the external water pipe through the fixed plate 3 and the fixed hole, so as to facilitate the injection of hot water into the water tank. In step 7, water pump 5 can then be used to inject water into the spray pan 23. The presence of ten spray pipes 22 accelerates the injection of hot water into the spray pan 23, further improving the device's efficiency. The ladder 12 facilitates workers climbing to the top of the cooling tower body 1 for maintenance. The anti-rust coating on the ladder 12 extends its lifespan. The guardrail 8, mounting plate 10, and fixing groove 9 prevent foreign objects from entering the fixing cylinder 18, avoiding damage to the rotating fan blades 17. The support rods 13 and base plate 2 around the bottom of the cooling tower body 1 provide good support. The multiple support rods 13 reduce the pressure on each rod. All electrical equipment in this device is powered by an external power source.

[0031] In one aspect of this embodiment, the water inlet pipe 4 can be connected to an external water pipe through the fixing plate 3 and the fixing hole, thereby facilitating the injection of hot water into the water tank 7. Then, the water pump 5 can be used to inject water into the sprinkler plate 23. Since ten sprinkler pipes 22 are provided, the speed of hot water injection into the sprinkler plate 23 can be accelerated, which is beneficial to further improve the working efficiency of the device. Moreover, the device has a simple structure and is easy to implement.

[0032] In one aspect of this embodiment, after the hot water is cooled, it can enter the drain tank 15. When there is too much water inside the cooling tower body 1, the switch valve can be opened so that the water inside the cooling tower body 1 can be discharged through the drain pipe 14. The support rods 13 and the base plate 2 provided around the bottom of the cooling tower body 1 can provide good support for the cooling tower body 1. Since there are multiple support rods 13, the pressure borne by each support rod 13 can be reduced.

[0033] In one aspect of this embodiment, the escalator 12 is provided so that workers can easily climb to the top of the cooling tower body 1, thereby facilitating maintenance and increasing the convenience and functionality of the device. Furthermore, since the surface of the escalator 12 is provided with an anti-rust coating, the service life of the escalator 12 can be increased. The guardrail 8, the mounting plate 10, and the fixing groove 9 are provided to prevent foreign objects from entering the fixed cylinder 18 and avoid damage to the rotating fan blades 17.

[0034] Working principle: First, the water pump is started to draw water from the water tank. Then, the water is injected into the spray tray through the connecting water pipe, fixed water pipe, and spray pipe. When the water level in the spray tray is higher than the first or second water outlet array, the water will be sprayed out through the nozzles, so that the water is evenly sprayed on the heat sink. The heat sink dissipates heat by increasing the surface area. The motor can also be started to drive the rotating fan blades to rotate, thereby expelling the hot air inside the cooling tower body, which is conducive to rapid heat dissipation and improves the cooling efficiency of the device.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
