Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and specifically discloses a cooling tower with a wind and sand protection structure. Background Technology

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and release it into the atmosphere to lower the water temperature. It utilizes the principle of heat exchange between water and air to generate steam, which evaporates and carries away heat to dissipate 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 barrel-shaped, hence the name cooling tower.

[0003] Existing cooling towers are generally placed outdoors for use. Due to the abundance of wind, sand, and dust outdoors, some cooling towers have poor wind and sand protection, which can easily damage the internal equipment and reduce the service life of the cooling tower. Secondly, some cooling towers are equipped with dustproof components, but after a long period of use, wind and sand dust adhere to the dustproof components, affecting airflow and reducing the cooling tower's effectiveness. To address these issues, existing equipment needs to be improved. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0022] Please see Figure 1-4A cooling tower with a wind and sand prevention structure includes a cooling tower 1. The cooling tower 1 includes a tower body 2, an air outlet duct 3 disposed at the top of the tower body 2 and communicating with the tower body 2, a fan 4 disposed inside the air outlet duct 3, a water collector 5, a water distributor 6, packing material 7, a water collection pool 8, and an air inlet 9 arranged in a ring below the side wall of the tower body 2 from top to bottom within the tower body 2; it also includes a first sand prevention mechanism and a second sand prevention mechanism respectively disposed on the air outlet duct 3 and the air inlet 9; the first sand prevention mechanism includes a sleeved... The filter plate 10 is located inside the air outlet duct 3 and above the fan 4, with the top of the filter plate 10 and the top of the air outlet duct 3 on the same plane. A ring-shaped support sleeve 11 is provided below the filter plate 10. The second sand prevention mechanism includes a ring-shaped sandproof filter sleeve 12 and a sealing plate 13. The sandproof filter sleeve 12 is fitted onto the air inlet window 9. The sealing plates 13 are symmetrically arranged in groups at the top and bottom of the sandproof filter sleeve 12. The two sealing plates 13 are located above and below the air inlet window 9 and are detachably connected to the tower body 2.

[0023] In this embodiment: the sand-proof filter sleeve 12 is installed on the tower body 2 through the sealing plates 13 on the upper and lower sides. When outside air enters the air inlet window 9, it first passes through the sand-proof filter sleeve 12 and then through the air inlet window 9 before entering the tower body 2, which can optimize air circulation. The filter plate 10 on the top plate filters the air outlet duct 3, preventing sand and dust from entering the tower body 2 from the air outlet duct 3. The support sleeve 11 supports the filter plate 10, ensuring the stability of the filter plate 10 in the air outlet duct 3. When the fan 4 is running, the air in the tower body 2 flows from bottom to top, making it easy to clean the sand and dust filtered on the filter plate 10. The top of the filter plate 10 is on the same plane as the top of the air outlet duct 3, preventing sand and dust from accumulating on the filter plate 10. This gives the cooling tower 1 the function of preventing sand and dust. When the cooling tower 1 is running, outside air enters the cooling tower 1 through the air inlet 9. The air provides the necessary oxygen for the packing 7 and the water distributor 6 to support the evaporation and heat dissipation process of water. The water distributor 6 is responsible for spraying the cooling water evenly onto the packing 7. Through the even distribution of the water distributor 6, the cooling water can cover the surface of the packing 7 in the form of fine water droplets, thereby increasing the contact area between water and air and improving the evaporation efficiency. The water and air exchange heat in the packing 7. The cooling water forms a thin film on the surface of the packing 7 and evaporates, taking away heat and thus achieving the cooling effect. The fan 4 is started. The fan 4 rotates to generate wind power, which pushes the air to circulate inside the cooling tower 1. It exhausts the hot air from the top of the tower and at the same time draws in fresh air into the air inlet 9 to maintain the continuous cooling process.

[0024] As a technical optimization of this utility model, a cone-shaped sand-proof cloak 14 is provided above the filter plate 10, and a number of connecting rods 15 fixedly connected to the top of the filter plate 10 are arranged in a circular array at the top of the sand-proof cloak 14.

[0025] In this embodiment, the sand-proof cloak 14 protects the filter plate 10 and prevents external sand from accumulating on the top of the filter plate 10.

[0026] As a technical optimization of this utility model, a threaded sleeve 16 is threadedly connected to the outer circumference of the air outlet duct 3, and a number of support rods 17 fixed to the bottom of the windproof sandproof cloak 14 are arranged in an inclined circular array on the outer circumference of the threaded sleeve 16.

[0027] In this embodiment: the threaded sleeve 16 is fixedly connected to the sand-proof awning 14 via the support rod 17. By rotating the threaded sleeve 16, the sand-proof awning 14 can be easily installed above the air outlet duct 3.

[0028] As a technical optimization of this utility model, the interior of the windproof sand filter sleeve 12 is provided with a cleaning mechanism for cleaning the windproof sand filter sleeve 12; the cleaning mechanism includes a movable and arc-shaped air distribution plate 18 and a fan 19 disposed on the air distribution plate 18; an air distribution cavity 20 is opened in the interlayer of the air distribution plate 18, and an air distribution hole 21 communicating with the air distribution cavity 20 is opened on the side of the air distribution plate 18 near the windproof sand filter sleeve 12, and the input end of the fan 19 is connected to the air distribution cavity 20 through a pipe.

[0029] In this embodiment: when the fan 19 is started, the flowing air enters the air distribution chamber 20 of the air distribution plate 18 and flows out from multiple air distribution holes 21 to blow onto the sandproof filter sleeve 12. The flowing air blows from inside the sandproof filter sleeve 12 to the outside, making it easy to clean the dust and sand filtered on the sandproof filter sleeve 12; and the air distribution plate 18 can be moved, making it easy to thoroughly clean the sandproof filter sleeve 12, preventing the sandproof filter sleeve 12 from becoming clogged, and making it easy to continuously optimize the air circulation of the sandproof filter sleeve 12, thereby improving the heat dissipation effect and service life of the cooling tower 1.

[0030] As a technical optimization of this utility model, the top plate of the air distribution plate 18 is provided with a rotating sleeve 22, a meshing toothed sleeve 23, a drive wheel 24, and a motor 25; the outer circumferential wall of the meshing toothed sleeve 23 is fixedly connected to the inner circumferential wall of the rotating sleeve 22, and the meshing toothed sleeve 23 is connected to the drive wheel 24 in a transmission manner; the motor 25 is embedded in the bottom of the upper sealing plate 13, and the output shaft of the motor 25 is coaxially fixedly connected to the drive wheel 24; a ring-shaped groove 26 is opened at the bottom of the upper sealing plate 13, and the upper end of the rotating sleeve 22 is rotatably disposed in the groove 26.

[0031] In this embodiment: the motor 25 is started, the drive wheel 24 and the meshing gear sleeve 23 are driven to rotate the rotating sleeve 22 in the groove 26, and when the rotating sleeve 22 rotates, it drives the air distribution plate 18 to rotate synchronously, which makes it easy for the air distribution plate 18 to thoroughly clean the windproof sand filter sleeve 12.

[0032] As a technical optimization of this utility model, a reinforcing sleeve 27 is provided at the center of the outer circumference of the windproof sand filter sleeve 12. The upper and lower sides of the outer wall of the reinforcing sleeve 27 are respectively provided with reinforcing ribs 28 that are fixedly connected to the bottom of the upper sealing plate 13 and the top of the lower sealing plate 13.

[0033] In this embodiment, the sand-proof filter sleeve 12, the reinforcing rib 28, and the sealing plate 13 form a right triangle. When the cooling tower 1 is running, the reinforcing sleeve 27 and the reinforcing rib 28 enable the sand-proof filter sleeve 12 to withstand a certain wind pressure and load, effectively improving the load-bearing capacity of the air inlet window 9, ensuring its stable operation, and preventing the sand-proof filter sleeve 12 from deforming. When encountering severe weather conditions such as strong winds and heavy rain, the reinforcing rib 28 can effectively reduce the swaying and vibration of the sand-proof filter sleeve 12, ensuring that it can continue to stably provide airflow to the cooling tower 1.

[0034] As a technical optimization of this utility model, a galvanized steel mesh 29 is provided between the two sealing plates 13 located above and below, and the windproof sand filter sleeve 12 is located inside the galvanized steel mesh 29. The inner circumference of the windproof sand filter sleeve 12 is provided with a circular array of connecting ribs 30 that are fixedly connected to the outer circumference of the reinforcing sleeve 27.

[0035] In this embodiment, the mesh size of the galvanized steel mesh 29 is larger than that of the sand-proof filter sleeve 12, which can block large foreign objects from the outside and optimize air circulation; the galvanized steel mesh 29 has strong anti-corrosion performance, improves structural strength, and improves the heat dissipation effect and service life of the cooling tower 1; and the sand-proof filter sleeve 12 is placed inside the galvanized steel mesh 29, which can protect the sand-proof filter sleeve 12.

[0036] Working principle and usage process of this utility model:

[0037] The sand-proof filter sleeve 12 is installed on the tower body 2 via sealing plates 13 on both the upper and lower sides. When outside air enters the air inlet window 9, it first passes through the sand-proof filter sleeve 12 for filtration, and then passes through the air inlet window 9 again before entering the tower body 2. This optimizes airflow and provides the necessary oxygen for the packing 7 and water distributor 6. The motor 25 is started, and the drive wheel 24 and meshing gear sleeve 23 drive the rotating sleeve 22 to rotate the air distribution plate 18. The fan 19 is also started, and the flowing air blows from inside the sand-proof filter sleeve 12 outwards, making it easy to clean the dust and sand filtered on the sand-proof filter sleeve 12. Furthermore, the air distribution plate 18 is movable, facilitating a thorough cleaning of the sand-proof filter sleeve 12 and preventing sand from entering the tower body. The filter sleeve 12, which is easy to block, continuously optimizes airflow, thereby improving the heat dissipation effect and service life of the cooling tower 1. The filter plate 10 on the top plate filters the air outlet duct 3, preventing sand and dust from entering the tower body 2 from the air outlet duct 3. The support sleeve 11 supports the filter plate 10, ensuring the stability of the filter plate 10 in the air outlet duct 3. The sand-proof awning 14 can be installed above the air outlet duct 3 through the threaded sleeve 16, so that the sand-proof awning 14 protects the filter plate 10 and prevents external sand and dust from accumulating on the top plate of the filter plate 10. When the fan 4 is running, the air in the tower body 2 flows from bottom to top, making it easy to clean the sand and dust filtered on the filter plate 10.
