Description

Technical Field

[0001] The utility model relates to the technical field of wind barrier blade design for an air inlet of a cooling tower, in particular to a wind barrier blade used for an air inlet of a cooling tower. Background Art

[0002] A cooling tower is a device used to remove waste heat from an industrial process or air conditioning system. It cools water (or other fluids) primarily by transferring heat to the atmosphere. Wind barrier blades, also known as wind guide blades, wind deflectors or wind guide blades, are usually installed at the air inlet of the cooling tower. The main function of these blades is to guide the air flow to the inside of the cooling tower and reduce unexpected air flow disturbances caused by side winds. Wind barrier blades are usually located at the air inlet or inlet direction of the cooling tower and help guide airflow from all angles to the inside of the cooling tower. To ensure that the cooling tower obtains sufficient airflow and provides a good cooling effect. The material of the wind barrier blades is usually a lightweight, corrosion-resistant alloy material, such as aluminum alloy or fiberglass.

[0003] Compared with the Chinese patent with application number CN202320280950.9, a wind barrier blade at the air inlet of a cooling tower and a cooling tower are disclosed. The air inlet is divided into a sealing part, a control part and a normally open part from top to bottom, and the wind barrier blade includes a sealing plate and a rotating plate. The sealing part is provided with a sealing plate that can be adjusted up and down, and the control part is rotatably provided with a rotating plate. When operating in winter, the sealing plate is pulled down to completely seal the sealing part, which can reduce the amount of cold air entering, reduce the wind speed at the air inlet, increase the temperature at the air inlet, and reduce the freezing phenomenon at the air inlet. An inlet flow channel and an outlet flow channel are formed inside the rotating plate. The inlet flow channel is connected to the water inlet pipe of the cooling tower through a pipeline. The high-temperature circulating hot water of the cooling tower is used to heat the rotating plate, increase the temperature at the air inlet position, and avoid freezing at the air inlet position.

[0004] The disadvantages of the above patent are: hot water flows from one end of the pipeline to the other end, and the temperature continues to drop during the process. The temperature difference between the liquid inlet and the liquid outlet of the pipeline is large, and the antifreeze effect at the liquid outlet is not good. Utility Model Content

[0024] like Figure 1-4 As shown, an embodiment of the utility model provides a wind barrier blade for an air inlet of a cooling tower, comprising a plurality of drainage devices 1 evenly arranged up and down, a power device 2 is arranged outside the drainage device 1, and a heating device 3 is arranged behind the power device 2.

[0025] like Figure 2 As shown, the drainage device 1 includes a support tube 101 , a drainage blade 102 is fixedly provided on the outer side of the support tube 101 , a partition plate 103 is fixedly provided in the middle of the support tube 101 , and the partition plate 103 is integrally formed with the support tube 101 .

[0026] In this embodiment, the guide device 1 is evenly installed on the installation frame 201. When the cooling tower drives the airflow to pass through the installation frame 201, the guide blades 102 block part of the airflow from entering the cooling tower, thereby completing the adjustment of the air intake volume.

[0027] like Figure 3As shown, the power device 2 includes a mounting frame 201, a plurality of sprockets 202 are staggeredly arranged on one side of the mounting frame 201, a chain 203 is arranged between the sprockets 202, two gears 204 are arranged on one side of the sprocket 202 at the bottom, a motor 205 is installed on one side of the gear 204, the gear 204 at the rear is connected to the bearing of the mounting frame 201, and the gear 204 at the front is connected to the drainage device 1 with a flat key.

[0028] In this embodiment, when it is necessary to adjust the angle of the guide blade 102 to change the air flow rate, the installation frame 201 supports the motor 205 to drive the gear 204 located at the back to rotate, and the gear 204 located at the front is engaged to rotate. The gear 204 drives the bottom sprocket 202 to rotate through the coaxial support tube 101, and the sprocket 202 then drives the top sprocket 202 to rotate synchronously through the chain 203. Similarly, the cross-distributed chains 203 drive all the sprockets 202 to rotate in the same direction, so that all the support tubes 101 drive the guide blades 102 to rotate around the installation frame 201 at the same angle, thereby completing the adjustment of the angle of the guide blades 102. By providing a staggered sprocket 202 on one side of the support tube 101, the independent motor 205 can drive any number of guide blades 102 to open and close evenly, thereby improving the linkage of the device and saving costs.

[0029] like Figure 4 As shown, the heating device 3 includes a liquid inlet box 301, two liquid outlet boxes 302 are symmetrically installed on both sides of the liquid inlet box 301, a number of liquid inlet pipes 303 are arranged on both sides of the liquid inlet box 301, a number of liquid outlet pipes 304 are arranged on the inner side of the liquid outlet box 302, and bellows 305 are arranged on the inner sides of the liquid inlet pipes 303 and the liquid outlet pipes 304, and a connecting piece 306 is arranged on the inner side of the bellows 305, and the connecting piece 306 is flange-connected to the budget support pipe 101.

[0030] In this embodiment, when the support tube 101 rotates, it drives the bellows 305 to expand and contract to keep the pipeline unobstructed. The partition plate 103 divides the support tube 101 into two upper and lower liquid flow channels respectively. The liquid inlet box 301 draws the hot water inside the cooling tower into the liquid inlet pipe 303 respectively, and then passes through the bellows 305 and the connecting piece 306 to enter the support tube 101, wherein the hot water flows from left to right in the upper flow channel and from right to left in the lower flow channel, thereby completing the uniform heating of the support tube 101 and preventing the guide blades 102 from freezing. Finally, the hot water cooled in the two flow channels flows into the liquid outlet box 302 along the left and right liquid outlet pipes 304 respectively to complete the water recovery work. By setting a two-way flow channel in the support tube 101, the liquid inlet pipe 303 and the liquid outlet pipe 304 are staggered to solve the problem that the hot water flows in the pipeline and cools down continuously when the single flow channel is used, resulting in a large temperature difference between the liquid inlet and the liquid outlet of the pipeline, resulting in poor antifreeze effect at the liquid outlet, and further improving the antifreeze stability of the blades.

[0031] It should be noted that the utility model is a wind barrier blade for the air inlet of a cooling tower. The guide device 1 is evenly installed on the installation frame 201. When the cooling tower drives the air flow to pass through the installation frame 201, the guide blade 102 blocks part of the air flow from entering the cooling tower to complete the adjustment of the air intake volume. When it is necessary to adjust the angle of the guide blade 102 to change the air flow rate, the installation frame 201 supports the motor 205 to drive the gear 204 at the back to rotate, and the gear 204 at the front is engaged to rotate. The gear 204 drives the bottom sprocket 202 to rotate through the coaxial support tube 101, and the sprocket 202 then drives the top sprocket 202 to rotate synchronously through the chain 203. Similarly, the cross-distributed chains 203 drive all the sprockets 202 to rotate in the same direction, so that all the support tubes 101 drive the guide blades 102 to rotate around the installation frame 201 at the same angle to complete the adjustment of the angle of the guide blades 102. By providing a staggered sprocket 202 on one side of the support tube 101, the independent motor 205 can drive any number of The guide blades 102 open and close evenly, improving the linkage of the device and saving costs. When the support pipe 101 rotates, the bellows 305 is driven to expand and contract to keep the pipeline unobstructed. The partition plate 103 divides the support pipe 101 into two upper and lower liquid flow channels. The liquid inlet box 301 draws the hot water inside the cooling tower into the liquid inlet pipe 303, and then passes through the bellows 305 and the connecting piece 306 to enter the support pipe 101. The hot water flows from left to right in the upper flow channel and from right to left in the lower flow channel, completing the support. The tube 101 is evenly heated to prevent the guide blade 102 from freezing. Finally, the hot water cooled in the two flow channels flows into the liquid outlet box 302 along the left and right liquid outlet pipes 304 respectively to complete the water recovery work. By setting a two-way flow channel in the support tube 101, the liquid inlet pipe 303 and the liquid outlet pipe 304 are staggered to solve the problem of continuous cooling of hot water flowing in the pipeline in a single flow channel, resulting in a large temperature difference between the liquid inlet and the liquid outlet of the pipeline, resulting in poor antifreeze effect at the liquid outlet, thereby further improving the antifreeze stability of the blades.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
