Description

Technical Field

[0001] The present invention relates to the technical field of air coolers, and more particularly to an air flow driving component for an industrial air cooler and a driving method thereof. Background Art

[0002] Industrial air coolers use water evaporation to absorb heat, thereby achieving a cooling effect. It contains a water circulation system, evaporation media and a fan. The evaporation media is arranged on the side wall of the air cooler. The water circulation system provides water to the evaporation media through a water pump. The evaporation media is a water curtain paper with a honeycomb sandwich structure. The water curtain paper can effectively absorb moisture and dissipate it into the air. When the fan is running, air blows through the water curtain paper, and the water absorbs a lot of heat and evaporates and mixes with the air, so the temperature of the air will decrease. The cooled air is blown from the air outlet into the environment, thereby achieving the purpose of cooling.

[0003] At present, most industrial air coolers use ordinary fan blades to blow air. When the fan is arranged on the side (the wind blows out from the side of the air cooler), it is sufficient for use. However, when the fan is arranged on the top (the wind blows out from the top of the air cooler, this type of air cooler is generally equipped with water curtain paper on all four sides), the wind speed of the water curtain paper part close to the fan will be greater than that of the water curtain paper part far away from the fan, resulting in a decrease in cooling efficiency. Therefore, this type of air cooler generally uses cross-flow fan blades.

[0004] For dusty workshops, crossflow fan blades are very easy to get dusty. A lot of dust accumulates on the blades, which hinders the operation of the fan and reduces or even eliminates the wind. At this time, the air cooler needs to be disassembled for cleaning. The crossflow fan blades of the air cooler can only be set under the motor, and the bottom of the air cooler is the water tank. Therefore, if it is disassembled for cleaning, the motor and the crossflow fan blades need to be removed for cleaning, which takes a lot of time. Summary of the invention

[0035] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0036] Refer to the instruction manual Figure 1-Figure 12 The industrial air cooler includes a box body 1, a water tank 2 is installed at the bottom of the box body 1, and the water tank 2 is used to store water. Evaporative media 11 are installed around the box body 1. The evaporative media 11 is a water curtain paper with a honeycomb sandwich structure. A water tank 12 is installed at the upper end of each evaporative media 11. The water pump 8 pumps the water in the water tank 2 into the water tank 12. A row of holes is opened at the bottom of the water tank 12, and the water flows from the holes to the evaporative media 11. An airflow driving component is set in the box body 1. The airflow driving component draws air from the outside through the water curtain paper to the inside of the box body 1. When the air blows through the water curtain paper, the water absorbs a large amount of heat to evaporate and mix with the air, so the temperature of the air will be reduced, and the cooled air is blown from the air outlet pipe 13 to the environment, thereby achieving the purpose of ventilation and cooling.

[0037] Refer to the instruction manual Figure 1-Figure 12The present embodiment provides an air flow drive assembly for an industrial air cooler, including a bracket 3, the bracket 3 is mounted on the top of the box 1 of the industrial air cooler, a motor 4 is mounted on the bracket 3, a main shaft 41 is mounted on the output end of the motor 4, a crossflow fan blade 5 is fixedly mounted on the main shaft 41, and the motor 4 is used to drive the crossflow fan blade 5 to rotate through the main shaft 41. The outer side and inner side of the crossflow fan blade 5 are respectively provided with an outer water retaining telescopic assembly 6 and an inner water retaining telescopic assembly 7, when the outer water retaining telescopic assembly 6 extends upward, an outer cleaning space 51 is formed between the crossflow fan blade 5, when the inner water retaining telescopic assembly 7 extends upward, an inner cleaning space 52 is formed between the crossflow fan blade 5, the blades of the crossflow fan blade 5 are located between the outer cleaning space 51 and the inner cleaning space 52, and the bottom of the crossflow fan blade 5 extends to the inside of the water tank 2 of the industrial air cooler, so that when the water tank 2 is full of water, the water submerges the bottom of the crossflow fan blade 5.

[0038] In the above technical solution, during normal ventilation and heat dissipation, the motor 4 drives the crossflow fan blades 5 to rotate through the main shaft 41, and the crossflow fan blades 5 draw external air into the interior of the crossflow fan blades 5, and then discharge it from the air outlet pipe 13 through the top of the crossflow fan blades 5. When a large amount of dust accumulates on the blades of the crossflow fan blade 5, it is necessary to clean it. The principle is to immerse the bottom of the crossflow fan blade 5 in the water in the water tank 2, and then the crossflow fan blade 5 rotates, so that the crossflow fan blade 5 can splash water to achieve the purpose of cleaning. However, since the space outside and inside the crossflow fan blade 5 is large, it is difficult for water to be brought to a higher height. Therefore, when cleaning, the outer water-retaining telescopic component 6 and the inner water-retaining telescopic component 7 are extended upward to form an outer cleaning space 51 and an inner cleaning space 52. The blades of the crossflow fan blade 5 are located between the outer cleaning space 51 and the inner cleaning space 52. By setting the outer water-retaining telescopic component 6 and the inner water-retaining telescopic component 7, the redundant parts of the outer space and the inner space of the blades of the crossflow fan blade 5 can be removed. At this time, if the crossflow fan blade 5 rotates again, the water inside the outer cleaning space 51 and the inner cleaning space 52 can be splashed to a higher height, thereby cleaning.

[0039] In the above technical solution, specifically, Figure 4 , Figure 6-Figure 9 As shown, the outer water-retaining telescopic assembly 6 includes an outer lower ring 61, which is arranged on the outer side of the bottom of the cross-flow fan blade 5, and an outer upper ring 62 is arranged directly above the outer lower ring 61. The outer lower ring 61 and the outer upper ring 62 are fixed by an outer plastic film 63. The outer plastic film 63 is an inner and outer double-layer structure, and an outer water storage space 64 capable of accommodating water is provided between the inner and outer double-layer structures. An outer water inlet 65 connected to the outer water storage space 64 is provided at the bottom of the outer lower ring 61. When water is supplied from the outer water inlet 65 to the outer water storage space 64, the outer upper ring 62 extends upward.

[0040] Furthermore, the outer water-retaining telescopic assembly 6 also includes a plurality of outer fixing rods 66 , the tops of the outer fixing rods 66 are fixedly connected to the bracket 3 , the outer lower ring 61 is fixedly connected to the outer side of the bottom of the outer lower ring 61 , and the outer upper ring 62 is slidably sleeved on the outer sides of the plurality of outer fixing rods 66 .

[0041] It should be noted that when water is supplied from the external water inlet 65 to the interior of the external water storage space 64, the external plastic film 63 is gradually propped up, so that the outer upper ring 62 moves upward along the external fixing rod 66 to form the outer cleaning space 51. The setting of the external fixing rod 66 prevents the outer upper ring 62 from being skewed when moving upward.

[0042] In the above technical solution, specifically, Figure 4 , Figure 6-Figure 9 As shown, the inner water-retaining telescopic assembly 7 includes an inner lower circle 71, which is arranged on the inner side of the bottom of the cross-flow fan blade 5, and an inner upper circle 72 is arranged directly above the inner lower circle 71. The inner lower circle 71 and the inner upper circle 72 are fixed by an inner plastic film 73. The inner plastic film 73 is an inner and outer double-layer structure, and an inner water storage space 74 capable of accommodating water is provided between the inner and outer double-layer structures. A water inlet rod 76 connected to the inner water storage space 74 is provided in the middle of the inner lower circle 71. When water is supplied from the water inlet rod 76 to the inner water storage space 74, the inner upper circle 72 extends upward.

[0043] Furthermore, the internal water-retaining telescopic assembly 7 also includes a plurality of internal fixed rods 75, the top of the internal fixed rod 75 is fixedly connected to the bracket 3, the inner lower circle 71 is fixedly connected to the outer position of the bottom of the internal fixed rod 75, the inner upper circle 72 is slidably sleeved on the outer sides of the plurality of internal fixed rods 75, the upper end of the crossflow fan blade 5 is an open structure, the bottom of the crossflow fan blade 5 has a connecting frame, and the bottom of the main shaft 41 is fixedly connected to the connecting frame.

[0044] It should be noted that when water is supplied from the water inlet rod 76 to the inner water storage space 74, the inner plastic film 73 is gradually propped up, so that the inner upper ring 72 moves upward along the inner fixing rod 75 to form the inner cleaning space 52. The inner fixing rod 75 is provided to prevent the inner upper ring 72 from being skewed when moving upward.

[0045] In the above technical scheme, specifically, a water pump 8 is arranged inside the water tank 2, a water supply seat 81 is fixedly connected to the middle part of the water tank 2, the bottom of the main shaft 41 is rotatably connected to the upper end of the water supply seat 81, both ends of the water inlet rod 76 are fixedly connected to the inner lower ring 71, and the inner lower ring 71 is movably sleeved on the outer side of the main shaft 41, the bottom of the main shaft 41 has a water supply cavity 411, the water supply cavity 411 is connected to the water inlet rod 76, one side of the water supply seat 81 has a water inlet pipe 82, the output end of the water pump 8 is connected to the water inlet pipe 82 and the external water inlet 65 through a reversing valve, and the water pump 8 is connected to the water tank 12 of the industrial air cooler through the reversing valve.

[0046] It should be noted that the reversing valve adopts a two-position three-way electromagnetic reversing valve, which is used to control the water pump 8 to be connected with the water inlet pipe 82 and the external water inlet 65 or to control the water pump 8 to be connected with the water tank 12. The water pump 8 adopts a forward and reverse water pump. When the water pump 8 is connected with the water inlet pipe 82 and the external water inlet 65, and the water pump 8 supplies water to the water inlet pipe 82 and the external water inlet 65, water enters the interior of the external water storage space 64 and the internal water storage space 74, so that the outer upper circle 62 and the inner upper circle 72 move upward. When the water pump 8 pumps water out of the external water storage space 64 and the internal water storage space 74, the outer upper circle 62 and the inner upper circle 72 move downward. When the water pump 8 is connected with the water tank 12, the water pump 8 pumps water into the water tank 12 and flows to the evaporation medium 11, and the water on the evaporation medium 11 flows into the water tank 2 to realize water circulation.

[0047] It should be noted that the water inlet rod 76 is in a stationary state, and a plurality of holes are provided on the side wall at the upper end of the water supply cavity 411 , which are connected to the water inlet rod 76 , so that water can enter the water inlet rod 76 from the main shaft 41 through the holes and then enter the interior of the internal water storage space 74 .

[0048] Specifically, in the case of ventilation and heat dissipation, it is necessary to ensure that the bottom of the crossflow fan blade 5 is not immersed in the water inside the water tank 2. The water pump 8 supplies water to the water tank 12 through the reversing valve. The water flows from the water tank 12 to the evaporation medium 11 and then flows to the inside of the water tank 2. The air is drawn from the outside to the inside of the box body 1 through the water curtain paper through the air flow driving component. The air blows through the water curtain paper, and the cooled air is blown into the environment from the air outlet pipe 13. In the case of cleaning the crossflow fan blade 5, the water pump 8 supplies water to the inside of the external water storage space 64 and the internal water storage space 74 through the reversing valve, so that the outer upper circle 62 and the inner upper circle 72 move upward to form the outer cleaning space 51 and the inner cleaning space 52, and then water is added to the inside of the water tank 2 from the water inlet pipe on the water tank 2, so that the bottom of the crossflow fan blade 5 is submerged in the water, and then the motor 4 drives the crossflow fan blade 5 to rotate, so that the water splashes, and the cleaning purpose is achieved.

[0049] The above technical scheme can achieve the purpose of ventilation and heat dissipation by setting the crossflow fan blades 5, the outer water-retaining telescopic assembly 6 and the inner water-retaining telescopic assembly 7. The motor 4 drives the crossflow fan blades 5, and the wind speed at each position of the evaporation medium 11 can be kept basically consistent through the crossflow fan blades 5, thereby improving the efficiency of ventilation and heat dissipation. When the crossflow fan blades 5 need to be cleaned, the outer water-retaining telescopic assembly 6 and the inner water-retaining telescopic assembly 7 are extended upward to form an outer cleaning space 51 and an inner cleaning space 52, so as to reduce useless space and enable the water to splash higher when the crossflow fan blades 5 rotate, thereby achieving the purpose of comprehensive cleaning.

[0050] Refer to the instruction manual Figure 8-Figure 10It should be noted that when the cross-flow fan blades 5 are cleaned, waves will be generated inside the water tank 2 due to the rotation. In order to prevent the waves from flowing from the evaporative medium 11 to the outside, specifically, wave baffles 9 are hinged on all sides of the water tank 2, and the ends of adjacent wave baffles 9 are connected by elastic membranes 91.

[0051] Furthermore, control components 100 are installed all around the outer upper ring 62, and the control components 100 include a fixed cylinder 101, which is fixedly connected to the outer upper ring 62, and a push rod 102 is laterally movably inserted inside the fixed cylinder 101. An elastic component 103 is provided inside the fixed cylinder 101, and the elastic component 103 is used to reset the push rod 102 toward the outside of the cross-flow fan blades 5. The upper and lower sides of the front end of the push rod 102 are both inclined surfaces, and the push rod 102 is used to push the wave baffle 9 upward or downward.

[0052] Furthermore, a limiting plate 90 corresponding to the wave baffle 9 is fixedly connected to the side wall of the water tank 2. When the bottom of the wave baffle 9 contacts the upper end of the limiting plate 90, the upper surface of the wave baffle 9 tilts toward the middle of the water tank 2.

[0053] It should be noted that, under normal conditions, one end of the wave baffle 9 close to the crossflow fan blade 5 is tilted downward, so that the water flowing down from the evaporative medium 11 can flow downward along its surface to the inside of the water tank 2 without flowing to the outside of the box body 1. When the crossflow fan blade 5 needs to be cleaned, the outer upper circle 62 moves upward, which will drive the control component 100 to move upward, and the push rod 102 pushes the end of the wave baffle 9 upward to rotate the wave baffle 9 upward, and the elastic membrane 91 is stretched. The more the wave baffle 9 rotates upward, the greater the tension of the elastic membrane 91. Therefore, the end of the push rod 102 will move a certain distance toward the inside of the fixed tube 101 and then leave the wave baffle 9. A damping sleeve is provided at the hinge between the wave baffle 9 and the water tank 2 to prevent the wave baffle 9 from rotating downward spontaneously. At this time, the wave baffle 9 and the elastic membrane 91 jointly surround the water tank 2 to prevent waves from overflowing. When cleaning is completed, the outer upper ring 62 drives the control assembly 100 to move downward, and the push rod 102 pushes the wave baffle 9 downward to make the wave baffle 9 swing downward. After the wave baffle 9 contacts the limit plate 90, it stops moving, and the push rod 102 continues to move downward to the bottom of the wave baffle 9. Among them, the elastic component 103 is a compression spring.

[0054] Refer to the instruction manual Fig.12 This embodiment also provides an industrial air cooler air flow driving method, using the above-mentioned industrial air cooler air flow driving component, including the following steps:

[0055] When ventilation and cooling are performed: the motor 4 drives the crossflow fan blades 5 to rotate through the main shaft 41, so that the crossflow fan blades 5 draw the air outside the industrial air cooler from the evaporative medium 11 into the interior of the box 1 and discharge it from the air outlet pipe 13. In this process, the water pump 8 supplies water to the interior of the water tank 12, so that the water flows to the evaporative medium 11;

[0056] When cleaning the crossflow fan blades 5, follow the steps below:

[0057] Step 1: supply water to the outer water storage space 64 and the inner water storage space 74 through the water pump 8, so that the outer upper ring 62 and the inner upper ring 72 move upward, so that the cross-flow fan blades 5 are located between the outer cleaning space 51 and the inner cleaning space 52;

[0058] Step 2: Add water into the water tank 2 so that the water covers the bottom of the crossflow fan blades 5;

[0059] Step 3: The motor 4 drives the crossflow fan blades 5 to rotate, and the crossflow fan blades 5 drive the water inside the water tank 2 to clean the blades of the crossflow fan blades 5.

[0060] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
