[0019] 2. The present invention sets a return air collection-release mechanism so that the return air in the return air main pipe enters the air collecting bag after passing through the connecting pipe. When the return air gathered in the air collecting bag is not enough, the upper and lower first magnetic blocks press the air outlet part together due to the attraction between each other, that is, the air outlet part is sealed. In this way, the return air is prevented from participating in the air circulation for a certain period of time, and more fresh air from the outside can be allowed to participate in the air circulation, thereby improving the overall quality of the clean room air. As the return air continues to enter the air collecting bag, the return air in the air collecting bag will increase, thereby making the air collecting bag swell larger and larger. In the process of continuous expansion, the air collecting bag is also a process of pulling the upper and lower two first magnetic blocks apart. When the air collecting bag is expanded to a certain extent, the two first magnetic blocks will be separated. Furthermore, because the spring itself has a certain pulling force on the first magnetic block, this In this way, at the moment when the two first magnetic blocks are separated, the first magnetic block will be quickly pulled outward, so that the air outlet part will be instantly opened, so that the return air originally gathered in the air collecting bag will quickly pass through the air outlet part and the through hole to reach the wind turbine generator set, wherein the through hole is directly facing the wind wheel of the wind turbine generator set, and the return air coming out of the air collecting bag is not only large in volume but also concentrated, and the speed is also fast, which greatly improves the efficiency and effect of power generation of the wind turbine generator set, because the fresh air is relatively scattered after passing through the primary filter plate, which may cause the power generation effect of the wind turbine generator set to be not so ideal, with the continuous release of the return air in the air collecting bag, the air collecting bag will shrink until the upper and lower first magnetic blocks close the air outlet part again, and the next round of air collection process is carried out, and it is circulated back and forth like this, which greatly improves the quality of circulating air in the clean room and the power generation effect of the wind turbine generator set;

[0020] 3. The present invention arranges the air outlet portion to consist of two fixed sections, a first telescopic section and a second telescopic section, wherein the first tip portion and the second tip portion are both arranged to exceed the vertical center line, and the second tip portion is located below the first tip portion, so that when the first telescopic section and the second telescopic section are compressed, the first tip portion and the second tip portion will alternately overlap, thereby achieving a good sealing effect;

[0021] 4. The present invention fully humidifies and heats the air through the provision of an air humidifying mechanism and an air heating mechanism, and can well prevent water mist from escaping to the left and right sides. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following will be combined with the attached embodiment of the present invention Figure 1-10 The technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The present invention provides a technical solution: a clean room air circulation device, comprising a fresh air duct 1, the fresh air duct 1 is connected to an air treatment mechanism 2, the upper right end of the air treatment mechanism 2 is connected to an air supply duct 3, the air supply duct 3 is connected to a clean room 4, return air columns 5 are arranged on the left and right sides of the clean room 4, the top of the return air column 5 is connected to a return air duct 6, the return air duct 6 is connected to the air treatment mechanism 2, the air treatment mechanism 2 comprises a box body 7, the interior of the box body 7 is provided with a primary filter plate 8, a wind turbine 9, an air humidification mechanism 10, an air heating mechanism 11, a fan 12 and a medium efficiency filter 13 from left to right, when working, the fan 12 is started, and the outside fresh air enters the air treatment mechanism 2 through the fresh air duct 1 for processing, wherein the primary filter plate 8 mainly filters dust, pollen, dust and other particulate matter in the air, wherein the wind turbine 9 uses the air (that is, wind) entering the air treatment mechanism 2 to carry out Generate electricity, and the electric energy stored in the electricity generation is used to provide electric energy for the air humidifying mechanism 10 and the air heating mechanism 11 in the air treatment mechanism 2. In this way, the wind turbine generator set 9 makes good use of the wind energy in the air treatment mechanism 2 to provide electric energy for the air humidifying mechanism 10 and the air heating mechanism 11 in the air treatment mechanism 2, which greatly saves electric energy and achieves a good energy-saving effect. The air humidifying mechanism 10 humidifies the external dry air to a certain extent, and the air heating mechanism 11 heats the air to a certain extent. Then the air is filtered to a higher degree through the medium efficiency filter 13, wherein the medium efficiency filter 13 can be a bag-type medium efficiency filter. The air filtered by the medium efficiency filter 13 is sent to the inside of the clean room 4 through the air supply duct 3, and the air inside the clean room 4 is returned to the air treatment mechanism 2 through the return air column 5 and the return air duct 6 to participate in the air circulation, and it is circulated back and forth to provide clean air for the clean room 4. Figure 2 As shown, the return air column 5 is a hollow column surrounded by a baffle and the wallboard of the clean room 4, wherein a plurality of return air ports are arranged below the baffle, wherein an induced draft fan can be arranged in the return air column 5 or the return air duct 6, so that the return air effect can be better. The wind turbine generator set 9 belongs to the prior art, so its structure and principle are not described in detail here.

[0036] The air supply duct 3 includes an air supply main pipe 14 connected to the upper right end of the air handling mechanism 2, and a plurality of air supply branch pipes 15 are connected to the air supply main pipe 14, and an air supply port 16 is connected to the air supply branch pipe 15. The air supply port 16 is fixed on the top plate of the clean room 4, and the air supply port 16 is connected to the interior of the clean room 4. This is the specific structure of the air supply duct 3. Through the arrangement of the air supply branch pipe 15, the interior of the clean room 4 can be evenly supplied with air, so that the air supply effect is better.

[0037] The return air duct 6 includes a return air branch pipe 17 connected to the top of the return air column 5, the return air branch pipe 17 is connected to the return air main pipe 18, the return air main pipe 18 is connected to the upper left end of the box body 7 and is connected to the interior of the box body 7. This is the specific structure of the return air duct 6, wherein the left and right return air columns 5 are connected to the return air main pipe 18 through the return air branch pipe 17.

[0038] A return air collection-release mechanism 19 is provided between the primary filter plate 8 and the fresh air duct 3. The return air collection-release mechanism 19 includes a connecting pipe 20 connected to the return air main pipe 18. An air collecting bag 21 is fixed to the right end of the connecting pipe 20. An air outlet portion 22 of the air collecting bag 21 is fixed with two upper and lower first magnetic blocks 23. The outer end of the first magnetic block 23 is fixed with the inner end of a spring 24. The outer end of the spring 24 is fixed to the inner wall of the box body 7. A through hole 25 is provided on the primary filter plate 8 at a position opposite to the first magnetic block 23. The working principle of the return air collection-release mechanism 19 is as follows: the return air in the return air main duct 18 enters the air collecting bag 21 after passing through the connecting pipe 20. When the return air gathered in the air collecting bag 21 is not enough, the upper and lower first magnetic blocks 23 press the air outlet part 22 together due to the attraction between each other, that is, the air outlet part 22 is sealed. In this way, the return air is prevented from participating in the air circulation within a certain period of time, and more fresh air from the outside can participate in the air circulation, thereby improving the overall quality of the clean room air. As the return air continues to enter the air collecting bag 21, the return air in the air collecting bag 21 will increase, and then the air collecting bag 21 will become larger and larger. In the process of continuous expansion, the air collecting bag 21 is also a process of pulling the upper and lower first magnetic blocks 23 apart. When the air collecting bag 21 expands to a certain extent, the two first magnetic blocks 23 will be separated. Since the spring 24 itself has a certain pulling force on the first magnetic block 23, the first magnetic block 23 will be quickly pulled outward at the moment the two first magnetic blocks 23 are separated, which will The air outlet 22 is opened instantly, so that the return air originally gathered in the air collection bag 21 will quickly pass through the air outlet 22 and the through hole 25 to reach the wind turbine 9, wherein the through hole 25 is directly opposite to the wind wheel of the wind turbine 9, and the return air coming out of the air collection bag 21 is not only large in volume but also concentrated, and the speed is also fast, which greatly improves the efficiency and effect of the wind turbine 9 in power generation, because the fresh air is relatively scattered after passing through the primary filter plate 8, which may cause the power generation effect of the wind turbine 9 to be not so ideal. With the continuous release of the return air in the air collection bag 21, the air collection bag 21 will shrink until the upper and lower first magnetic blocks 23 close the air outlet 22 again, and the next round of air collection process will be carried out, and the cycle will be repeated. Since the spring 24 has a strong elasticity after being quickly pulled away from the first magnetic block 23, it will drive the first magnetic block 23 to move up and down, which is also convenient for the upper and lower first magnetic blocks 23 to close the air outlet 22 again. The material of the air collecting bag 21 can be rubber, which not only makes the air collecting bag 21 have strong elasticity, but also makes the air outlet 22 pressed between the two first magnetic blocks 23 have better sealing. The primary filter plate 8 is provided with a slide groove 48, and the first magnetic block 23 is provided with a slider 49 matching the slide groove 48. This setting realizes the sliding connection between the first magnetic block 23 and the primary filter plate 8, which plays a role in limiting the first magnetic block 23. Fig.11 As shown, in order to better separate the upper and lower first magnetic blocks 23, a blocking plate 47 is fixed at one end of the first magnetic block 23 close to the spring 24, so that during the filling process of the air collecting bag 21, when it contacts the blocking plate 47, it will push the blocking plate 47 outward, and then push the first magnetic block 23 fixed to the blocking plate 47 outward, thereby facilitating the separation of the upper and lower first magnetic blocks 23.

[0039] The air outlet portion 22 includes a fixed section 26 fixed to the first magnetic block 23, and a first telescopic section 27 and a second telescopic section 28 are provided between the upper and lower fixed sections 26. The first telescopic section 27 is formed by connecting a plurality of first V-shaped sections 29, wherein the first tip portion 30 of the first V-shaped section 29 faces inward and exceeds the vertical center line 31 of the first magnetic block 23, and the second telescopic section 28 is formed by connecting a plurality of second V-shaped sections 32, wherein the second tip portion 33 of the second V-shaped section 32 faces inward and exceeds the vertical center line 31 of the first magnetic block 23, and the second tip portion 33 is located below the first tip portion 30, wherein the fixed section 26 is used for fixing to the first magnetic block 23, and the setting of the first telescopic section 27 and the second telescopic section 28 facilitates the contraction and opening of the air outlet portion 22. The first tip portion 30 and the second tip portion 33 are both arranged to exceed the vertical center line 31, and the second tip portion 33 is located below the first tip portion 30, so that when the first telescopic section 27 and the second telescopic section 28 are compressed, the first tip portion 30 and the second tip portion 33 will overlap alternately, thereby achieving a good sealing effect.

[0040] Second magnetic blocks 34 are fixed to both outer ends of the bottom surface of the upper first magnetic block 23. The thickness of the second magnetic block 34 is slightly smaller than the sum of the thicknesses of the first telescopic section 27 and the second telescopic section 28 after compression. This arrangement can firmly press the first telescopic section 27 and the second telescopic section 28 between the upper and lower first magnetic blocks 23.

[0041] The air humidification mechanism 10 includes a partition 35, a water tank 36 is fixed at the bottom of the right side of the partition 35, a water pump is arranged in the water tank 36, a vertical water outlet pipe 37 is fixedly connected to the water outlet of the water pump, a plurality of horizontal water outlet pipes 38 are evenly distributed on the vertical water outlet pipe 37, a plurality of spray heads 39 are arranged on the horizontal water outlet pipe 38, and a plurality of air holes 40 are arranged on the partition 35 between adjacent horizontal water outlet pipes 38. The principle of the air humidification mechanism 10 is as follows: the wind turbine 9 provides electric energy for the water pump, and the water pump starts to pump water in the water tank 36 to the vertical water outlet pipe 37. The water mist enters the horizontal water outlet pipe 38 through the vertical water outlet pipe 37, and is sprayed out through the sprinkler head 39 on the horizontal water outlet pipe 38. The air passes through the water mist after passing through the air holes 40 on the partition 35, and the air is effectively humidified by the water mist. The fallen water mist re-enters the water tank 36 to participate in the circulation. The setting of the partition 35 effectively prevents the water mist from escaping to the left side of the partition 35. Although the partition 35 is provided with air holes 40, the air is blown toward the water mist from the air holes 40, so the water mist can be prevented from passing through the air holes 40 to enter the left side of the partition 35.

[0042] The air heating mechanism 11 includes a heating seat 41 fixedly connected to the water tank 36, and an aluminum honeycomb panel 42 is fixed on the heating seat 41, wherein the wind power generation group 9 provides electric energy for the heating seat 41, and the aluminum honeycomb panel 42 is heated by the heating seat 41. The humidified air can be fully heated after passing through the aluminum honeycomb panel 42, and the method of humidifying the air first and then heating it can avoid the disadvantages of the method of heating the air first and then humidifying it. In the background technology, the air is first heated and then humidified. In this way, the heat of the heated air will be greatly lost after humidification. The method of humidifying first and then heating can preserve the heat well and remove moisture appropriately.

[0043] A plurality of honeycomb holes 43 are arranged on the aluminum honeycomb panel 42, and the honeycomb holes 43 are arranged in an inclined shape with the left side lower and the right side higher. By arranging the honeycomb holes 43 in an inclined shape with the left side lower and the right side higher, a good flow guiding effect can be achieved, and water mist can be effectively prevented from escaping to the right side of the aluminum honeycomb panel 42. In order to better heat the air, a spiral plate can be fixed in the honeycomb hole 43, so that the air passes through the honeycomb hole 43 for a longer time, thereby achieving a better heating effect.

[0044] A nano silver antibacterial gel filter 44, a photocatalyst filter 45 and an activated carbon filter 46 are provided between the wind turbine 9 and the air humidification mechanism 10 from left to right. The nano silver antibacterial gel filter 44 can sterilize the air, the photocatalyst filter 45 can eliminate harmful substances such as formaldehyde and benzene from the air, and the activated carbon filter 46 can deodorize the air. The nano silver antibacterial gel filter 44, the photocatalyst filter 45 and the activated carbon filter 46 can greatly improve the air purification effect.

[0045] Working principle: When working, the fan 12 is started, and the outside fresh air enters the air treatment mechanism 2 through the fresh air duct 1 for processing, wherein the primary filter plate 8 mainly filters the dust, pollen, dust and other particulate matter in the air, wherein the wind turbine generator set 9 uses the air (that is, wind) entering the air treatment mechanism 2 to generate electricity, and the electric energy stored in the generated electricity is used to provide electric energy for the air humidification mechanism 10 and the air heating mechanism 11 in the air treatment mechanism 2, so that the wind turbine generator set 9 makes good use of the wind energy existing in the air treatment mechanism 2, and provides the air humidification mechanism 10 and the air heating mechanism 11 in the air treatment mechanism 2. The air humidification mechanism 10 humidifies the dry air to a certain extent, and the air heating mechanism 11 heats the air to a certain extent. Then, the air is filtered to a higher degree through the medium efficiency filter 13, wherein the medium efficiency filter 13 can be a bag medium efficiency filter. The air filtered by the medium efficiency filter 13 is sent to the inside of the clean room 4 through the air supply duct 3, and the air inside the clean room 4 is returned to the air treatment mechanism 2 through the return air column 5 and the return air duct 6 to participate in the air circulation, and the cycle is repeated to provide clean air for the clean room 4. The return air in the return air main pipe 18 enters the air collection bag 21 after passing through the connecting pipe 20. When the return air collected in the air collection bag 21 is not enough, the upper and lower first magnetic blocks 23 press the air outlet 22 together due to the attraction between each other, that is, the air outlet 22 is sealed, so that the return air is prevented from participating in the air circulation within a certain period of time, and more fresh air from the outside can be allowed to participate in the air circulation, thereby improving the overall quality of the clean room air. As the return air continues to enter the air collecting bag 21, the return air in the air collecting bag 21 will increase, and then the air collecting bag 21 will become larger and larger. In the process of continuous expansion, the air collecting bag 21 is also a process of pulling the upper and lower first magnetic blocks 23 apart. When the air collecting bag 21 expands to a certain extent, the two first magnetic blocks 23 will be separated. Since the spring 24 itself has a certain pulling force on the first magnetic block 23, the first magnetic block 23 will be quickly pulled outward at the moment the two first magnetic blocks 23 are separated, which will The air outlet 22 is opened instantly, so that the return air originally gathered in the air collection bag 21 will quickly pass through the air outlet 22 and the through hole 25 to reach the wind turbine 9, wherein the through hole 25 is directly facing the wind wheel of the wind turbine 9. The return air coming out of the air collection bag 21 is not only large in volume but also concentrated, and the speed is also fast, which greatly improves the efficiency and effect of the wind turbine 9. Because the fresh air is relatively scattered after passing through the primary filter plate 8, this may cause the power generation effect of the wind turbine 9 to be not so ideal. With the continuous release of the return air in the air collection bag 21, the air collection bag 21 will shrink until the upper and lower first magnetic blocks 23 close the air outlet 22 again, and the next round of air collection process is carried out, and the cycle is repeated.
