Description

Technical Field

[0001] The utility model relates to the field of dust prevention of cooling towers, in particular to a dust prevention structure of a cooling tower. Background Art

[0002] A cooling tower is a device used to lower water temperature. It is usually used in industrial production, air conditioning systems, power plants, chemical plants and other places. It transfers heat from water to air through air flow, thereby lowering the temperature of the water. When the cooling tower is in operation, air enters through the air inlet and is then discharged through the air outlet by a fan. In this process, in order to prevent dust from affecting the air inlet and outlet, dust-proof structures are installed at these two locations. The dust-proof structure on the air outlet of the existing device can only play a dust-proof shielding effect, and its function is relatively simple. In addition, since the cooling tower is too high, debris is easily accumulated on the dust-proof structure, affecting the air guiding efficiency of the air outlet.

[0003] Therefore, a cooling tower dustproof structure is now developed in response to the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the existing device that can only play the role of dust shielding and has a relatively single function, and because the cooling tower is too high, debris is easily accumulated on the dustproof structure to affect the air guiding efficiency of the air outlet, the utility model provides a cooling tower dustproof structure.

[0005] The technical implementation scheme of the utility model is: a dustproof structure of a cooling tower, including a base, an isolation net is placed on the base, nine heat-conducting fins are connected to the lower side of the isolation net, the heat-conducting fins are used to further dissipate heat so that water vapor can quickly liquefy and drip, and a closing mechanism for shielding and dustproofing the upper part of the isolation net is provided on the base.

[0006] Optionally, the closing mechanism includes a mounting seat, which is connected to the upper left side of the base, a closing curtain for covering the upper part of the isolation net is wound on the mounting seat, a spiral spring is connected between the closing curtain and the mounting seat, guide groove frames are connected to the front and rear sides of the upper part of the base by bolts, the guide groove frames are slidably connected to the closing curtain, the right part of the guide groove frames is connected to guide slides, limit blocks are slidably connected to the guide slides, a first spring is connected between the limit blocks and the adjacent guide groove frames, and the limit blocks are used to limit and block the closing curtain.

[0007] Optionally, a limiting mechanism is further included, which includes a limiting column. The front and rear sides of the base are slidably connected with limiting columns for fixing the isolation net, and a second spring is connected between the limiting column and the base.

[0008] Optionally, the middle part of the isolation net is a wave structure for guiding the liquefied water flow.

[0009] Optionally, the pulling portion at the outer end of the closed curtain is connected to a power assist rod.

[0010] Optionally, the right portion of the guide slot frame is a downwardly inclined structure.

[0011] By adopting the above technical solution, compared with the prior art, the utility model has the following advantages:

[0012] The utility model is installed above the fan at the top of the cooling tower, and the base is fixedly installed by bolts. As the cooling tower fan is started, the hot air in the cooling tower will be transported upward. During the upward movement of the hot air, it will contact the isolation net, and with the assistance of the heat dissipation fins, the heat will be quickly dissipated. After the heat in the hot air is dissipated, it will begin to liquefy and form water droplets attached to the lower side of the isolation net. The wavy structure of the isolation net is used to guide the water droplets, so that the water droplets drip along the isolation net, forming a water circulation inside the cooling tower, and avoiding excessive evaporation of cooling water.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0020] A cooling tower dustproof structure, such as Figure 1-Figure 3 As shown, it includes a base 1, on which an isolation net 2 is placed. The middle part of the isolation net 2 is a wave structure for guiding the liquefied water flow. Nine heat-conducting fins 3 are connected to the lower side of the isolation net 2. The heat-conducting fins 3 are used to further dissipate heat so that water vapor can be quickly liquefied and drip. The base 1 is provided with a closing mechanism 4 for shielding the upper part of the isolation net 2 from dust.

[0021] like Figure 1 , Figure 4 and Figure 5 As shown, the closing mechanism 4 includes a mounting seat 41, the mounting seat 41 is connected to the upper left side of the base 1, a closing curtain 42 for shielding the upper part of the isolation net 2 is wound on the mounting seat 41, the outer end pulling portion of the closing curtain 42 is connected to a power rod, a volute spring 43 is connected between the closing curtain 42 and the mounting seat 41, the front and rear sides of the upper part of the base 1 are connected with guide slot frames 44 by bolts, the guide slot frames 44 are slidably connected to the closing curtain 42, the right part of the guide slot frames 44 are all downwardly inclined structures, the right part of the guide slot frames 44 are connected to guide slides 45, the guide slides 45 are slidably connected to limit blocks 46, the limit blocks 46 and the adjacent guide slot frames 44 are connected with first springs 47, and the limit blocks 46 are used to limit and block the closing curtain 42.

[0022] It should be noted that the device is installed above the fan at the top of the cooling tower, and the base 1 is fixedly installed by bolts. As the cooling tower fan is started, the hot air in the cooling tower will be transported upward. During the upward movement of the hot air, it will contact the isolation net 2, and with the assistance of the heat dissipation fins, the heat will be quickly dissipated. After the heat in the hot air is dissipated, it will begin to liquefy and form water droplets attached to the lower side of the isolation net 2. The wavy structure of the isolation net 2 is used to guide the water droplets, so that the water droplets drip along the isolation net 2, forming a water circulation inside the cooling tower to avoid excessive evaporation of cooling water. When the cooling tower is not in use, in order to avoid a large amount of dust and debris adhering to the isolation net 2, the closed curtain 42 can be pulled to the right along the guide groove frame 44. During the process of pulling the closing curtain 42, the spiral spring 43 will be deformed by force until the closing curtain 42 contacts the limit block 46, and the limit block 46 is squeezed by the closing curtain 42, so that the limit block 46 slides downward, and the first spring 47 is compressed. As the pulling part of the closing curtain 42 contacts the right side of the guide groove frame 44, the limit block 46 is no longer squeezed. Under the action of the first spring 47, the limit block 46 will slide upward and reset, and block and lock the closing curtain 42. When the cooling tower enters the working state, the limit block 46 can be pulled downward so that the limit block 46 no longer blocks the closing curtain 42. Under the action of the spiral spring 43, the closing curtain 42 will move to the left and be rolled up and reset. Example 2

[0023] On the basis of Example 1, Figure 1 and Figure 4 As shown, it also includes a limiting mechanism 5, which includes a limiting column 51. The front and rear sides of the base 1 are slidably connected with the limiting columns 51 for fixing the isolation net 2, and a second spring 52 is connected between the limiting column 51 and the base 1.

[0024] It should be noted that, since the isolation net 2 is placed on the base 1, in order to maintain the stability of the isolation net 2, the isolation net 2 is installed by clamping with the cooperation of the limit column 51 and the second spring 52, so that the isolation net 2 can maintain the placement stability.

[0025] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
