Description

Technical Field

[0001] This utility model relates to the field of air membrane technology, and in particular to a fresh air filtration and treatment device for air membrane buildings. Background Technology

[0002] Air-supported membrane structures are a new type of building that uses a special membrane material as its outer shell. The entire structure is supported by an internal air pressure higher than the external air pressure. Air-supported membrane structures have many advantages and characteristics: due to the flexibility and structural characteristics of the material, there are no components subjected to bending, torsion, or compression; no internal frame or beam / column support is required; and the span can reach 180 meters. The internal and external air pressure difference is typically 250 Pa, approximately 0.0025 atmospheres, equivalent to the air pressure difference between the first and ninth floors of a normal building, and will not have adverse effects on human health. Air-supported membrane structures are cost-effective. It has significant advantages. With the increase of span, the construction cost per unit area of ​​traditional buildings increases exponentially, while the opposite is true for air-supported membrane structures. As the span increases (up to 180 meters), the construction cost per unit area decreases. When the span exceeds 30 meters, the construction cost of air-supported membrane structures can be reduced by more than 50% compared to traditional buildings. The construction speed of air-supported membrane structures is very fast, with on-site construction taking no more than a week, which is unmatched by any other building structure. At the same time, air-supported membrane structures have low foundation requirements, are lightweight, can be built on top of existing buildings, and can be moved at any time.

[0003] However, the fresh air filtration equipment in air-supported structures usually uses fixed primary filters (such as metal mesh or non-woven fabric).

[0024] In severe weather conditions such as sandstorms and smog, the primary filter screen inside the air intake duct is prone to clogging. This invention incorporates a cleaning mechanism inside the air intake duct. The first driving component of the cleaning mechanism drives the first screw to rotate. Since both the cleaning unit and the tapping unit are installed between two first sliders, the first sliders do not rotate with the primary filter screen but instead move up and down.

When the air quality is good, the second drive component drives the second screw to rotate. Because one end of the second slider is hinged to a connecting rod, and the other end of the connecting rod is hinged to the end of the advanced filter away from the mounting edge, the second slider will move forward. The connecting rod will then drive the advanced filter to swing towards the air inlet side of the air inlet duct, thereby causing the advanced filter to fit against the inner wall of the air inlet duct and retract. This can effectively reduce the energy consumption of the fan and lower maintenance costs.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0040] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] Please refer to Figures 1-6 An embodiment of this utility model provides a fresh air filtration and treatment device for air-supported membrane structures, comprising:

[0042] Air inlet duct 9 extends in the first direction; the first direction is Figure 2 The front and back directions in the middle;

[0043] Fan 6 is located inside the air inlet duct 9 and away from the air inlet side of the air inlet duct 9. Fan 6 is used to introduce fresh air.

[0044] Cleaning mechanism 3 is located inside air inlet duct 9 and includes:

[0045] The primary filter 31 is located inside the air inlet duct 9 and close to the air inlet side of the air inlet duct 9;

[0046] The cleaning unit 32 is located on the side of the primary filter screen 31 near the air inlet of the air inlet duct 9 and is used to clean foreign objects on the primary filter screen 31.

[0047] The striking unit 33 is located on the side of the primary filter 31 near the air inlet of the air inlet duct 9 and is used to strike the primary filter 31.

[0048] The first drive unit 34 includes two first screws 341 disposed inside the air inlet duct 9. The two first screws 341 are located between the air inlet of the air inlet duct 9 and the primary filter screen 31. The two first screws 341 are arranged along a third direction on both sides of the primary filter screen 31, with the axis of the first screws 341 extending in a second direction. The first direction, the second direction, and the third direction are perpendicular to each other. Each of the two first screws 341 is externally connected to a first slider 342 via threads. The side of the first slider 342 closest to the primary filter screen 31 is connected to the cleaning unit 32. The side of the first slider 342 furthest from the primary filter screen 31 is provided with a first connecting plate 343, and the side of the first connecting plate 343 furthest from the wall of the air inlet duct 9 is connected to the striking unit 33. The first drive unit 34 also includes a first drive component 344 disposed on the air inlet duct 9, used to drive the first screws 341 to rotate, thereby moving the cleaning unit 32, the striking unit 33, and the first slider 342 along the second direction. The third direction is... Figure 2 The left and right directions, the second direction is Figure 2 The up and down directions in the middle.

[0049] In severe weather conditions such as sandstorms and smog, the primary filter 31 located inside the air intake duct 9 and near the air intake port is prone to clogging. The first drive component 344 drives the first screw 341 to rotate. Since the cleaning unit 32 and the tapping unit 33 are both installed between the two first sliders 342, the first sliders 342 do not rotate with it. Instead, they drive the cleaning unit 32 and the tapping unit 33 to move up and down. During the movement, the tapping unit 33 taps the primary filter 31, causing some dust to fall off. The cleaning unit 32 further cleans the dust on the primary filter 31, which can effectively prevent clogging and eliminate the need to replace the primary filter 31 in a short period of time.

[0050] Furthermore, the first screw 341 is provided with first fixing plates 345 at both ends. The first fixing plates 345 are installed inside the air inlet duct 9 to ensure the stable rotation of the first screw 341. The first drive component 344 can be a motor installed at the top of the air inlet duct 9. The output shaft of the motor is provided with a bevel gear, which meshes with the driven gear provided on the first screw 341. The motor can provide the power required for the stable rotation of the first screw 341.

[0051] In some embodiments, the cleaning unit 32 includes a cleaning plate 321 disposed on the side of the first slider 342 near the primary filter screen 31. The cleaning plate 321 is hollow inside. A water inlet 325 is provided on the side of the cleaning plate 321 away from the first slider 342. A plurality of evenly arranged brushes 323 are provided on the side of the cleaning plate 321 near the primary filter screen 31. The cleaning unit 32 also includes a water outlet 324 located on the cleaning plate 321 corresponding to the side of the brushes 323 along the up and down direction.

[0052] like Figure 3 and Figure 5 As shown, when the cleaning plate 321 moves up and down with the first slider 342, cleaning liquid can be injected into the cleaning plate 321 through the water inlet 325 connected by a hose. Several brushes 323 evenly arranged on the side of the cleaning plate 321 near the primary filter screen 31 will clean the primary filter screen 31. The water outlet 324 located on the side of the brushes 323 along the up and down direction of the cleaning plate 321 will spray out cleaning liquid to assist in cleaning. This can effectively clean the blockage on the primary filter screen 31 without frequent manual replacement of the primary filter screen 31.

[0053] In some embodiments, the striking unit 33 includes a gear 331 that meshes and drives with the first screw 341. A cam 332 is coaxially provided on the side of the gear 331 away from the first connecting plate 343. A striking hammer 333 is provided on one side of the cam 332 along a first direction. A second connecting plate 322 is provided on one end face of the cleaning plate 321 along a second direction. The striking hammer 333 is slidably mounted on the second connecting plate 322, and its sliding direction is the first direction. The striking hammer 333 is used to strike the primary filter screen 31. A striking spring 334 with its axis in the first direction is provided between the striking hammer 333 and the second connecting plate 322. One end of the striking spring 334 is used to connect the striking hammer 333, and the other end is used to connect the second connecting plate 322.

[0054] like Figure 3 , Figure 4 and Figure 5As shown, when the first connecting plate 343 moves up and down with the first slider 342, the gear 331, which is meshed and connected to the first screw 341, will rotate, and the cam 332, which is coaxially arranged with the gear 331, will also rotate. As the cam 332 rotates, the protruding part of the cam 332 will repeatedly contact one end of the hammer 333. When the two contact, the protruding part of the cam 332 will push the hammer 333 to move backward and strike the primary filter screen 31. When the two separate, the hammer 333 will be driven to reset under the action of the striking spring 334, thereby realizing the function of the hammer 333 reciprocating. As the cam 332 rotates, the hammer 333 will continuously strike the primary filter screen 31, which is beneficial to help clean the blockage on the primary filter screen 31.

[0055] Furthermore, a mounting shaft is provided on one side of the first connecting plate 343, and both gear 331 and cam 332 are mounted on the mounting shaft to ensure that gear 331 and cam 332 can rotate simultaneously and coaxially.

[0056] In some embodiments, an advanced filtration mechanism 4 is provided between the primary filter 31 and the fan 6. The advanced filtration mechanism 4 is used to filter fresh air in sandstorm or smog weather conditions. Figure 2 and Figure 6 As shown, an advanced filtration mechanism 4 is also provided between the primary filter 31 and the fan 6. The advanced filtration mechanism 4 can effectively filter foreign objects in the air during sandstorms and smog, thereby improving the quality of fresh air.

[0057] In some embodiments, the advanced filtration mechanism 4 includes:

[0058] The advanced filter 41 is located inside the air inlet duct 9 and between the primary filter 31 and the fan 6. A rubber strip is wrapped around the side surface of the advanced filter 41. The advanced filter 41 has an installation edge that is hinged to the inside of the air inlet duct 9, and the direction of its hinge axis is the second direction.

[0059] The second drive unit 42 includes a second screw 421 disposed inside the air inlet duct 9, a second slider 422 connected to the outside of the second screw 421 by a thread, a connecting rod 423 hinged to one end of the second slider 422, and the other end of the connecting rod 423 hinged to the end of the high-grade filter screen 41 away from the mounting edge; the axial direction of the second screw 421 is the first direction, and the hinge axis directions at both ends of the connecting rod 423 are the second direction; the second drive unit 42 also includes a second drive component 424 disposed on the air inlet duct 9, the second drive component 424 is used to drive the second screw 421 to rotate, drive the second slider 422 to move along the first direction, and cause the high-grade filter screen 41 to swing toward the air inlet side of the air inlet duct 9 through the connecting rod 423;

[0060] like Figure 2 and Figure 6 As shown, the advanced filter 41 has several second hinge seats 44 on its mounting edge that are hinged to the inside of the air inlet duct 9, and the advanced filter 41 can swing through the second hinge seats 44.

[0061] When the air quality is good, the second drive component 424 drives the second screw 421 to rotate. Since one end of the second slider 422 is hinged to the connecting rod 423 and the other end of the connecting rod 423 is hinged to the end of the high-grade filter 41 away from the mounting edge, the second slider 422 will move forward. The connecting rod 423 will then drive the high-grade filter 41 to swing towards the air inlet side of the air inlet duct 9, thereby making the high-grade filter 41 fit against the inner wall of the air inlet duct 9 and retracting the high-grade filter 41. This can effectively reduce the energy consumption of the fan 6 and reduce maintenance costs.

[0062] In sandstorm or smog weather, the second drive component 424 drives the second screw 421 to rotate, and the second slider 422 will move backward with the rotation of the second screw 421. The connecting rod 423 will also drive the high-grade filter 41 to swing in the opposite direction to the air inlet side of the air inlet duct 9, thereby achieving the purpose of placing the high-grade filter 41. The rubber strip wrapped around the side surface of the high-grade filter 41 can block the gap between the high-grade filter 41 and the inner wall of the air inlet duct 9, which can prevent the insufficiently filtered fresh air from escaping through the gap, and facilitate more complete filtration of fresh air.

[0063] Furthermore, the advanced filter screen 41 has a first hinge seat 43 at the end away from the installation edge, one end of the connecting rod 423 is connected to the second slider 422, and the other end is connected to the first hinge seat 43; the second screw 421 has second fixing plates 425 at both ends, and the second fixing plates 425 are installed inside the air inlet duct 9 to ensure the stable rotation of the second screw 421; the second drive component 424 can be a motor installed inside the side of the air inlet duct 9, and the motor drive shaft and output shaft are coaxially connected to the second screw 421, and the motor can provide the power required for the stable rotation of the second screw 421.

[0064] In some embodiments, an activated carbon filter 5 is provided inside the air intake duct 9 between the advanced filtration mechanism 4 and the fan 6. The activated carbon filter 5 is used to absorb odorous gases in the fresh air. Figure 2 As shown, an activated carbon filter 5 is installed inside the air intake duct 9 between the advanced filtration mechanism 4 and the fan 6. The activated carbon filter 5 can effectively absorb odor gases in the fresh air and improve the quality of the fresh air.

[0065] In some embodiments, a connecting pipe 8 is provided at the air outlet of the air inlet duct 9, and the side of the connecting pipe 8 away from the air inlet duct 9 is connected to the air-supported membrane structure 2; the fresh air filtration and treatment equipment 1 includes a cleaning mechanism 3, an advanced filtration mechanism 4, an activated carbon filter 5, a fan 6, a connecting channel 8, and an air inlet duct 9; the connecting pipe 8 is used to connect the fresh air filtration and treatment equipment 1 and the air-supported membrane structure 2, facilitating the entry of fresh air into the air-supported membrane structure 2; such as Figure 1 and Figure 2 As shown, a connecting pipe 8 is provided at the air outlet of the air inlet duct 9, and the air membrane structure 2 is connected to the side of the connecting pipe 8 away from the air inlet duct 9; the connecting pipe 8 can strictly prevent fresh air leakage and ensure that fresh air enters the air membrane structure 2 smoothly; preferably, the connecting pipe 8 is a flexible connecting pipe, which can effectively reduce the transmission of noise and vibration of the fan 6 into the air membrane structure 2.

[0066] In some embodiments, a dust collection trough 7 is further provided inside the air inlet duct 9 between the first screw 341 and the primary filter 31. The dust collection trough 7 is used to store and clean the debris removed by the primary filter 31; the fresh air filtration treatment device 1 also includes the dust collection trough 7, such as Figure 2 As shown, the air inlet duct 9 can be divided into two parts. The part of the air inlet duct 9 with the primary filter 31 close to the air inlet side is the first part, and the part of the air inlet duct 9 with the primary filter 31 away from the air inlet side is the second part. The cross-sectional area of ​​the first part is larger than that of the second part. The outer surface of the primary filter 31 fits with the inner surface of the second part, ensuring that all airflow passes through the primary filter 31. The first slider 342 in the first part has a longer displacement distance on the first screw 341, so that the displacement length of the first slider 342 is greater than the length of the primary filter 31. This is beneficial for the cleaning unit 32 and the tapping unit 33 on the first slider 342 to clean the primary filter 31 more thoroughly and without dead angles. A dust collection groove 7 is also provided inside the air inlet duct 9 between the first screw 341 and the primary filter 31. When the cleaning unit 32 and the tapping unit 33 clean the primary filter 31, the dust collection groove 7 can effectively collect the debris cleaned off the primary filter 31, which is convenient for subsequent manual cleaning.

[0067] In some embodiments, the air inlet duct 9 has several openings, each for installing a cleaning mechanism 3, an advanced filtration mechanism 4, an activated carbon filter 5, and a fan 6. The air inlet duct 9 also has sealing units corresponding to each opening, which are used to create a sealed environment within the air inlet duct 9. The several openings on the air inlet duct 9 facilitate the installation of various mechanisms and effectively accelerate construction efficiency. The sealing units, which are plates corresponding to each opening, effectively seal the openings, facilitating the formation of a sealed environment within the air inlet duct 9.

[0068] In severe weather conditions such as sandstorms and smog, dusty air enters the air intake duct 9 through the air inlet. The primary filter screen 31 is prone to clogging. The first drive component 344 drives the first screw 341 to rotate. Since the cleaning unit 32 and the tapping unit 33 are both installed between the two first sliders 342, the first sliders 342 do not rotate with them. Instead, they drive the cleaning unit 32 and the tapping unit 33 to move up and down. During the movement, the tapping unit 33 taps the primary filter screen 31, causing some dust to fall off. The cleaning unit 32 further cleans the dust on the primary filter screen 31, which can effectively prevent clogging and eliminate the need to replace the primary filter screen 31 in a short period of time.

[0069] The gas passing through the primary filter 31 will continue to be filtered by the advanced filter 41 and the activated carbon filter 5, thereby improving the quality of the fresh air. The filtered fresh air enters the air-supported membrane building 2 through the connecting channel 8.

[0070] When the air quality is good, the second drive component 424 drives the second screw 421 to rotate. Since one end of the second slider 422 is hinged to the connecting rod 423, and the other end of the connecting rod 423 is hinged to the end of the high-grade filter 41 away from the mounting edge, the second slider 422 will move forward. The connecting rod 423 will then drive the high-grade filter 41 to swing towards the air inlet side of the air inlet duct 9, thereby causing the high-grade filter 41 to fit against the inner wall of the air inlet duct 9 and retract the high-grade filter 41. This can effectively reduce the energy consumption of the fan 6 and reduce maintenance costs.
