In the industrial field, air coolers are often used to cool the hot air generated during the operation of large mechanical equipment to ensure the normal operation of the equipment and extend its service life. For example, in a power plant, it is used to cool the hot air generated by equipment such as generators and transformers.

[0003] During the operation of a traditional air cooler, in order to ensure the cleanliness of the air duct at its air inlet and prevent dust and foreign objects from entering and affecting the cooling effect, a dust-proof cover is usually carefully installed at the air inlet of the ventilation duct. However, under the existing technical conditions, whenever it is necessary to clean the dust-proof cover of the air cooler, it often has to be completely disassembled. This method not only consumes a large amount of time and manpower, but also has an extremely cumbersome operation process. In view of this, in order to significantly improve the dust cleaning efficiency of the dust-proof cover, another air cooler with a back-blowing dust removal structure is provided.

By arranging a forward and reverse rotation motor A with fan blades in the ventilation duct, opening a through hole at the top of the ventilation duct, and rotatably installing a sealing baffle in the duct that can open and close the through hole. When removing dust from the dust-proof cover, rotate the sealing baffle to open the through hole, start the motor A to rotate in reverse for reverse blowing, the air enters the ventilation duct through the through hole, passes through the dust-proof cover and then is discharged from the left end, realizing back-blowing dust removal. This process is simple and fast, without having to disassemble the dust-proof cover, and can effectively improve the dust cleaning efficiency, solving the problems of time-consuming, laborious and cumbersome operation when removing dust from the dust-proof cover of the existing air cooler. The specific technical solution is as follows:

Specific implementation mode

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0019] The front, back, left, right, up and down in this embodiment are described with Figure 1 as the reference plane. Please refer to Figures 1-4 , the present invention provides a technical solution:

[0020] An air cooler with an anti-blowing dust removal structure, including a ventilation duct 1 and a dust collection cloth bag 2, characterized in that dust-proof covers 11 and perforated connecting plates 12 are fixedly installed at the left and right ends of the ventilation duct 1, a reversible motor A 13 with a fan blade and a heat exchanger main body 14 are fixedly installed in the ventilation duct 1, the heat exchanger main body 14 is located on the right side of the reversible motor A 13, a through port 15 is penetrated and opened on the upper surface of the ventilation duct 1, a rotating rod 3 is rotatably installed in the ventilation duct 1, a sealing baffle 31 is sleeved on the outer surface of the rotating rod 3, when the sealing baffle 31 is perpendicular to the transverse inner wall of the ventilation duct 1, the inner cavity of the ventilation duct 1 is blocked, when the sealing baffle 31 is parallel to the transverse inner wall of the ventilation duct 1, the through port 15 is blocked, and the dust collection cloth bag 2 is detachably installed at the left end of the ventilation duct 1;

[0021] It should be noted that a reversible motor B 32 is fixedly installed on the front surface of the ventilation duct 1, and the output end of the reversible motor B 32 is fixedly connected to the front end of the rotating rod 3;

[0022] The ventilation duct 1 can be installed at the use place by driving the connecting plate 12. During normal use, the dust collection cloth bag 2 is separated and stored from the ventilation duct 1. After that, the reversible motor A 13 with a fan blade is started to introduce external air into the ventilation duct 1, and then the air flow is cooled by the heat exchanger main body 14 and then supplied to the use place to cool the equipment;

[0023] When dust removal is required for the dust-proof cover 11, such as Figure 2 and Figure 3As shown in the figure, first, the forward and reverse motor B32 drives the sealing baffle 31 to flip away from the through-port 15 through the rotating rod 3. When the sealing baffle 31 is perpendicular to the inner lateral wall of the ventilation duct 1 horizontally, the ventilation duct 1 is blocked and the through-port 15 is opened. Start the forward and reverse motor A13 to reverse, drive the fan blades on the outer surface of its output shaft to rotate in the reverse direction, introduce external air from the through-port 15, and discharge it from the ventilation duct 1 through the dust-proof cover 11, realizing the reverse blowing of the dust-proof cover 11 and achieving the dust removal effect. This process is simple and efficient, without the need to disassemble the dust-proof cover, and can effectively improve the dust cleaning efficiency.

[0024] To ensure the effect of reverse blowing dust removal, the distance between the forward and reverse motor A13 and the dust-proof cover 11 needs to be set to 10 - 20 cm.

[0025] It is worth noting that, as Figure 1 shown, connecting plates 4 are fixedly installed on the front and rear surfaces of the left end of the ventilation duct 1, and two card slots 41 are respectively and penetratingly opened on the left surfaces of the connecting plates 4. As Figure 4 shown, a metal frame 21 is fixedly installed on the right surface of the dust collection bag 2, and four clamping members 22 are symmetrically and fixedly installed on the right surface of the metal frame 21. The clamping members 22 are clamped and installed in the corresponding card slots 41, and an elastic rubber sealing ring 23 is fixedly installed on the right surface of the metal frame 21;

[0026] When using the dust collection bag 2, the clamping frame 22 can be clamped into the card slot 41 of the connecting plate 4 to complete the assembly between the dust collection bag 2 and the ventilation duct 1. After assembly, the elastic rubber sealing ring 23 abuts against the left surface of the dust-proof cover 11 to form a seal. When the dust in the dust-proof cover 11 is blown down in reverse, it will directly enter the dust collection bag 2 and be intercepted and collected, which can effectively avoid secondary dust pollution. After the dust removal is completed, manually lift the metal frame 21 to separate the clamping member 22 from the card slot 41, and then separate the dust collection bag 2 from the ventilation duct 1. After disassembly, adjust the position of the sealing baffle 31, block the through-port 15, and then rotate the forward and reverse motor A13 forward to make the air cooler work normally.
