Technical Field

[0001] This utility model relates to the field of air-supported membrane building technology, and in particular to a ventilation device for air-supported membrane buildings. Background Technology

[0002] Air-supported membrane structures refer to a building structure system that uses special architectural membrane materials as the outer shell and is equipped with a set of intelligent electromechanical equipment to provide positive air pressure inside the air-supported membrane structure to support the main body of the building. With its advantages such as lightweight, large span and short construction period, it has been widely used in sports stadiums, warehousing and logistics, industrial environmental protection and other fields.

[0003] Because the interior space of an air-supported structure is highly sealed, air circulation mainly relies on ventilation equipment. Common ventilation equipment for air-supported structures usually uses filters to filter the incoming air to prevent dust from entering the structure and affecting air quality. Over time, dust can accumulate on the filters, so they need to be cleaned regularly.

[0004] Existing ventilation equipment typically uses a fixed filter structure, with the filter installed inside the equipment. Cleaning or replacing the filter requires disassembling the outer casing, which is cumbersome and time-consuming. Utility Model Content

[0005] To overcome the drawbacks of cumbersome and time-consuming filter maintenance, this utility model provides a ventilation device for air-supported membrane structures.

[0006] The technical implementation scheme of this utility model is as follows: a ventilation device for air-supported membrane structures, comprising a support frame, a housing, a motor, fan blades, a protective cover, a filter frame, a filter, a fixing mechanism, and a humidification mechanism. The housing is provided on the upper side of the support frame, with an air inlet and an air outlet at the left and right ends of the housing, respectively. A motor is installed inside the housing, and the output shaft of the motor is connected to the fan blades. A protective cover is provided at the air inlet of the housing. Multiple filter frames are slidably provided on the right side of the inner side of the housing, with a filter in the middle of the filter frame. The front end of the filter frame extends out of the housing. Multiple fixing mechanisms are provided on the upper and lower sides of the right end of the housing for fixing the filter frames.

[0007] Optionally, the fixing mechanism includes a fixing seat and a lead screw. The front end of the filter frame is provided with fixing holes at the top and bottom, and the right end of the housing is provided with fixing seats on both the top and bottom sides. The fixing seat is threaded with a lead screw, and the lead screw is slidably connected to the fixing hole.

[0008] Optionally, the humidification mechanism includes a water distribution pipe, nozzles, a water supply pipe, a first valve, and a drainage mechanism. The humidification zone is located in the middle of the housing and gradually decreases in size from left to right. A water distribution pipe is located in the middle of the humidification zone and is situated between the fan blades and the filter frame. Multiple nozzles are evenly distributed on the water distribution pipe. A water supply pipe is connected to the water distribution pipe and passes through the outside of the housing to connect to a water source. A first valve is provided on the water supply pipe.

[0009] Optionally, the drainage mechanism includes a drain pipe, a second valve, and a baffle. The drain pipe is located at the lowest point on the lower side of the humidification zone, and the second valve is located on the drain pipe. A baffle is located on the left side of the humidification zone, and the baffle is located exactly to the left of the drain pipe.

[0010] Optionally, it also includes arc-shaped baffles, with arc-shaped baffles provided on both the left and right sides of the front part of the filter frame, and the shape of the side of the arc-shaped baffle closest to the filter screen is adapted to the outer side of the housing.

[0011] Optionally, a sealing layer is provided on the side of the arc-shaped baffle near the housing.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention filters dust, impurities and particulate matter in the air step by step through the protective cover at the air inlet and the multi-layer replaceable filter screen, which significantly improves the air cleanliness and meets the high requirements of air quality for air-supported membrane buildings; when it is necessary to install or remove the filter screen, the filter screen frame can be directly pulled out from the shell by releasing the fixing mechanism, which is convenient for replacing or maintaining the filter screen.

[0013] 2. This utility model introduces water from an external water source through a water supply pipe. After the flow rate is controlled by the first valve, the water enters the distribution pipe. The nozzles on the distribution pipe atomize the water evenly, forming fine water droplets that fully contact the air to complete humidification, thus regulating the humidity inside the air-supported membrane structure. The accumulated water is periodically discharged through the drain pipe and the second valve to prevent water accumulation from affecting the operation of the equipment. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0020] A ventilation device for air-supported membrane structures, such as Figures 1-4 As shown, it includes a support 1, a housing 2, a motor 3, a fan blade 4, a protective cover 5, a filter frame 6, a filter 61, a fixing mechanism, and a humidification mechanism. The housing 2 is located on the upper side of the support 1. The left and right ends of the housing 2 are the air inlet and the air outlet, respectively. The air outlet is connected to the interior of the air-supported structure. The motor 3 is installed inside the housing 2. The output shaft of the motor 3 is connected to the fan blade 4. The air inlet of the housing 2 is equipped with a protective cover 5, which is used to block large particles or debris. Multiple filter frames 6 are slidably arranged on the right side of the inner side of the housing 2. The filter frame 6 has a filter 61 in the middle. The front end of the filter frame 6 extends out of the housing 2 for easy gripping. Multiple fixing mechanisms are provided on the upper and lower sides of the right end of the housing 2. The fixing mechanisms are used to fix the filter frames 6.

[0021] In use, the motor 3 drives the fan blades 4 to rotate, creating a negative pressure at the air inlet of the housing 2. Outside air is drawn into the housing 2 through the air inlet. The drawn-in air first passes through the protective cover 5, which blocks large particles or debris. Then it passes through multiple filters 61, which filter dust, impurities, etc. in the air, purifying the air. If necessary, the humidification mechanism will humidify the air and regulate the humidity inside the air-supported membrane structure. When it is necessary to install or remove the filter 61, the upper and lower fixing mechanisms are released from fixing the filter frame 6. Then the filter frame 6 is slid out of the housing 2 for easy replacement or maintenance of the filter 61.

[0022] like Figure 3 As shown, the fixing mechanism includes a fixing seat 9 and a lead screw 10. The front end of the filter frame 6 is provided with fixing holes 8 at the top and bottom. The right end of the housing 2 is provided with fixing seats 9 on both the top and bottom. The lead screw 10 is threadedly connected to the fixing seat 9. The lead screw 10 is slidably connected to the fixing hole 8. When it is necessary to install or remove the filter frame 6, the lead screw 10 is rotated to slide in the fixing hole 8, thereby fixing or loosening the filter frame 6, which facilitates the replacement or maintenance of the filter.

[0023] like Figure 4As shown, the humidification mechanism includes a water distribution pipe 11, nozzles 12, a water supply pipe 13, a first valve 14, and a drainage mechanism. The humidification zone is located in the middle of the housing 2, gradually decreasing in size from left to right. A water distribution pipe 11 is located in the middle of the humidification zone, between the fan blades 4 and the filter frame 6. Multiple nozzles 12 are evenly distributed on the water distribution pipe 11. A water supply pipe 13 is connected to the water distribution pipe 11, penetrating the housing 2 and connecting to an external water source. A first valve 14 is installed on the water supply pipe 13, allowing water to be introduced from an external water source. After the flow rate is controlled by the first valve 14, water enters the water distribution pipe 11. The nozzles 12 on the water distribution pipe 11 evenly atomize the water, forming fine water droplets that fully contact the air to complete humidification.

[0024] like Figure 4 As shown, the drainage mechanism includes a drain pipe 15, a second valve 16, and a partition 17. The drain pipe 15 is located at the lowest point of the humidification zone, and the second valve 16 is installed on the drain pipe 15. The partition 17 is located on the left side of the humidification zone, and the partition 17 is located exactly to the left of the drain pipe 15. During the humidification process, water will gradually accumulate at the bottom of the humidification zone. Since the humidification zone gradually shrinks from left to right, the accumulated water will gradually flow to the drain pipe 15 at the left end of the humidification zone and be discharged periodically through the drain pipe 15 and the second valve 16 to prevent water accumulation from affecting the operation of the equipment. The partition 17 separates the accumulated water from components such as the motor 3 and the fan blade 4 to prevent water accumulation from affecting the operation of the equipment.

[0025] like Figure 3 As shown, it also includes an arc-shaped baffle 7. Arc-shaped baffles 7 are provided on both the left and right sides of the front part of the filter frame 6. The shape of the side of the arc-shaped baffle 7 near the filter screen 61 is adapted to the outer side of the housing 2. When installing the filter frame 6, the arc-shaped baffle 7 can play a certain positioning and limiting role, ensuring that the fixing hole 8 on the filter frame 6 is aligned with the screw 10, simplifying the installation process. After installation, the arc-shaped baffle 7 can also play a certain sealing role, preventing external debris from entering the housing 2.

[0026] The curved baffle 7 has a sealing layer on the side near the housing 2. The sealing layer can enhance the sealing between the filter frame 6 and the housing 2 and prevent air from leaking from the gap between the filter frame 6 and the housing 2.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
