Description

Technical Field

[0001] This utility model relates to the field of mushroom house construction technology, and in particular to a mushroom house ventilation system. Background Technology

[0002] In the mushroom cultivation industry, most existing mushroom cultivation buildings are single-story, with multi-story buildings being less common. Current ventilation methods in mushroom cultivation areas mainly include natural ventilation and mechanical ventilation systems. However, natural ventilation systems have extremely high requirements for environmental conditions and air quality, making it difficult to precisely control key parameters such as temperature, humidity, oxygen content, and cleanliness within the cultivation area, thus failing to meet the needs of modern intelligent cultivation. Existing mechanical ventilation systems typically use combined air conditioning units or fresh air handling units, delivering treated air into the cultivation area through ductwork. This type of system requires dedicated air conditioning rooms and complex ductwork networks, which not only occupy a large amount of space and are difficult to construct, but are also prone to airflow imbalances along the path, affecting the stability of oxygen content and cleanliness levels in each mushroom house, making it difficult to meet the refined environmental requirements for the growth of different mushroom species. Therefore, how to achieve precise control of airflow in mushroom houses has become an urgent technical problem to be solved. Utility Model Content

This provides a more stable and suitable environmental condition for the healthy growth of mushrooms and helps promote the development of the mushroom cultivation industry towards intelligence and efficiency.

[0025] Specifically, this invention simplifies the complex duct layout of existing ventilation systems by setting up a partition structure within the mushroom house, dividing the internal passage into a ventilation mezzanine and a clean corridor. The ventilation mezzanine connects to the external space as a channel for introducing fresh air, while the clean corridor serves as a key area for airflow distribution. This reduces the amount of pipe material used and avoids airflow loss caused by excessively long or numerous pipes, thus significantly improving the system's economy and ease of installation.

[0026] Through the synergistic effect of the pressurized air supply structure, conveying structure, pressure relief structure, and exhaust structure, this invention achieves efficient and precise control of environmental parameters such as temperature, humidity, oxygen content, and cleanliness within the mushroom house. The pressurized air supply structure evenly delivers air from the ventilation interlayer into the clean corridor, ensuring that the air quality meets expected requirements, such as the Class 100,000 cleanroom standard. The conveying structure further distributes the clean air to each sub-room, creating a good mixed-flow ventilation effect. The pressure relief and exhaust structures, through precise adjustment of the pressure difference, ensure a stable and orderly airflow within the mushroom house, thereby simulating the ventilation conditions under the natural growth environment of mushrooms and providing a more stable and suitable environment for the healthy growth of mushrooms.

[0027] This invention possesses significant economic and promotional value. By optimizing the ventilation system design, it avoids problems such as insufficient clean air volume and oxygen deficiency caused by airflow imbalance in existing methods, achieving a stable mixed-flow ventilation effect within the mushroom house while ensuring cleanliness requirements. Furthermore, this invention features a simple structure and is easy to maintain, making it suitable for the development needs of multi-story mushroom cultivation buildings. It can significantly reduce construction and operating costs, and is conducive to promoting the intelligent and efficient development of the mushroom cultivation industry.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Please refer to the following: Figure 1 , Figure 2 and Figure 3As shown, an embodiment of this utility model provides a mushroom house ventilation system, which includes a mushroom house 100, a partition structure 200, and a ventilation mechanism 300. The internal space of the mushroom house 100 is divided into an internal passage and multiple relatively independent sub-rooms 110 located on one or both sides of the internal passage. The partition structure 200 is located in the internal passage and divides the internal passage into a ventilation mezzanine 120 and a clean corridor 130 along the height direction. The ventilation mezzanine 120 is used to connect to the external space, and the partition structure 200 is provided with a connection between the ventilation mezzanine 120 and the clean corridor 130. The ventilation system 300 includes an air outlet 220; the ventilation system 300 includes a pressurized air supply structure 310 disposed in the ventilation interlayer 120 and used to connect the air outlet 220, a conveying structure 320 used to connect the clean corridor 130 and each sub-room 110, a pressure relief structure 330 used to connect the clean corridor 130 and each sub-room 110, and an exhaust structure 340 used to connect the external space and each sub-room 110. The pressurized air supply structure 310 is used to deliver air from the ventilation interlayer 120 to the clean corridor 130, and the conveying structure 320 is used to deliver air from the clean corridor 130 to each sub-room 110.

[0044] Overall, this mushroom house ventilation system overcomes the shortcomings of existing ventilation methods, such as complex ductwork, unbalanced airflow, and difficulty in precisely controlling environmental parameters. It achieves precise control of the airflow in the mushroom house, thereby enabling efficient and precise control of environmental parameters such as temperature, humidity, oxygen content, and cleanliness within the mushroom house. This provides a more stable and suitable environment for the healthy growth of mushrooms and helps promote the development of the mushroom farming industry towards intelligence and efficiency.

[0045] Specifically, this invention simplifies the complex duct layout of existing ventilation systems by setting a partition structure 200 within the mushroom house 100, dividing the internal passage into a ventilation interlayer 120 and a clean corridor 130. The ventilation interlayer 120 connects to the external space as a channel for introducing fresh air, while the clean corridor 130 serves as a key area for airflow distribution. This reduces the amount of pipe material used and avoids airflow loss caused by excessively long or numerous pipes, thus significantly improving the system's economy and ease of installation.

[0046] Through the synergistic effect of the pressurized air supply structure 310, the conveying structure 320, the pressure relief structure 330, and the discharge structure 340, this utility model achieves efficient and precise control of environmental parameters such as temperature, humidity, oxygen content, and cleanliness within the mushroom house 100.

[0047] The pressurized air supply structure 310 evenly delivers air from the ventilation interlayer 120 into the clean corridor 130, ensuring that the air quality meets the expected requirements, such as the Class 100,000 cleanroom requirements. The delivery structure 320 further distributes the clean air to each sub-room 110, forming a good mixed-flow ventilation effect. The pressure relief structure 330 and the exhaust structure 340 ensure that the airflow organization in the mushroom house 100 is stable and orderly by precisely adjusting the pressure difference, thereby simulating the ventilation conditions in the natural growth environment of mushrooms and providing a more stable and suitable environment for the healthy growth of mushrooms.

[0048] This invention has significant economic benefits and promotional value. By optimizing the design of the ventilation system, it avoids problems such as insufficient clean air volume and lack of oxygen caused by air volume imbalance in existing methods, and achieves a stable mixed airflow ventilation effect within the mushroom house while ensuring cleanliness requirements.

[0049] Furthermore, this utility model has a simple structure and is easy to maintain, making it suitable for the development needs of multi-story mushroom cultivation buildings. It can significantly reduce construction and operating costs and is conducive to promoting the development of the mushroom cultivation industry towards intelligence and efficiency.

[0050] In the embodiments of this utility model, such as Figure 1 In the embodiment shown, the partition structure 200 includes a purification panel ceiling 210 disposed in the internal channel, and a pressurized air supply structure 310 disposed on the purification panel ceiling 210.

[0051] By installing a cleanroom ceiling panel 210 as a partition structure 200 in the internal passageway and integrating the pressurized air supply structure 310 onto the cleanroom ceiling panel 210, the space utilization and airflow organization efficiency of the internal passageway are improved. The cleanroom ceiling panel 210 not only serves as a physical partition, ensuring orderly airflow between the ventilation interlayer 120 and the clean corridor 130, but also provides an ideal installation position for the pressurized air supply structure 310, enabling it to deliver fresh air to the clean corridor 130 more evenly.

[0052] Designers can adjust the number and arrangement of sub-rooms 110 according to usage needs, without specific restrictions. Preferably, multiple sub-rooms 110 are respectively set on both sides of the internal passage and arranged sequentially.

[0053] By setting multiple sub-rooms 110 on both sides of the internal passage and arranging them in sequence, the efficient utilization of the mushroom house 100 space and the optimized distribution of airflow organization are achieved.

[0054] This layout not only ensures the shortest air transport path between the clean corridor 130 and each sub-room 110, reducing wind resistance and energy loss, but also allows the fresh air supplied by the pressurized air supply structure 310 to be evenly distributed to each sub-room 110, effectively avoiding the problem of uneven air volume caused by distance differences. This further improves the control accuracy of environmental parameters such as temperature, humidity and oxygen content in the mushroom house 100, providing a more stable and balanced environmental condition for the healthy growth of mushrooms.

[0055] In the embodiments of this utility model, such as Figure 2 The embodiment shown includes a pressurized air supply structure 310 comprising a pressurized air supply cabinet 311, a first centrifugal fan 312 disposed in the pressurized air supply cabinet 311, and an air supply duct 313 for connecting the first centrifugal fan 312 and the air outlet 220. The pressurized air supply cabinet 311 is provided with an air inlet 3111 for connecting the ventilation interlayer 120. The first centrifugal fan 312 is used to transport the air in the pressurized air supply cabinet 311 to the air outlet 220 through the air supply duct 313.

[0056] By combining the pressurized air supply cabinet 311, the first centrifugal fan 312, and the air supply duct 313, efficient pressurization and uniform delivery of air within the ventilation interlayer 120 are achieved.

[0057] Specifically, the pressurized air handling unit 311, as the core equipment, can stably introduce air from the ventilation interlayer 120 through its air inlet 3111. With the powerful force of the first centrifugal fan 312, the air is pressurized and then accurately delivered to the air outlet 220 through the air supply pipe 313. This ensures that the air pressure and flow rate can meet the needs of the clean corridor 130, and effectively avoids the air volume loss and airflow instability problems that may occur in existing ventilation methods, thereby improving the operating efficiency and reliability of the entire mushroom house ventilation system.

[0058] Furthermore, the pressurized air supply structure 310 also includes a filter assembly, which is located upstream of the first centrifugal fan 312 and is used to filter the air.

[0059] The filtration components can efficiently filter the air introduced from the ventilation interlayer 120, removing particulate matter, dust, and other impurities. This prevents pollutants from entering the clean corridor 130 and sub-rooms 110 and affecting the mushroom growth environment. It not only enhances the system's purification capabilities but also provides a cleaner and more stable air source for subsequent airflow distribution. This further ensures precise control of environmental parameters such as temperature, humidity, and cleanliness within the mushroom house 100, while extending the equipment's service life and reducing maintenance costs.

[0060] Designers can adjust the specific structure of the filter assembly according to the usage requirements, and no specific restrictions are imposed here. Preferably, the filter assembly includes a primary filter 314 and a secondary filter 315 disposed in the pressurized air supply cabinet 311, and the primary filter 314 and the secondary filter 315 are sequentially disposed upstream of the first centrifugal fan 312.

[0061] By installing a primary filter 314 and a secondary filter 315 arranged in sequence in the pressurized air supply cabinet 311, the air filtration effect is further optimized through multiple filtration operations, thereby improving the air purification level.

[0062] The primary filter 314 effectively intercepts large dust and impurities, reducing the burden on subsequent filters, while the intermediate filter 315 deeply purifies smaller particles, thus ensuring that the air entering the clean corridor 130 meets the Class 100,000 cleanliness standard.

[0063] The tiered filtration process not only improves filtration efficiency and reduces the load on individual filters, extending the lifespan of filter components, but also ensures the stability and cleanliness of airflow, providing a better environmental environment for mushroom growth while reducing system maintenance frequency and costs.

[0064] In the embodiments of this utility model, such as Figure 1 and Figure 2 In the embodiment shown, multiple pressurized air supply structures 310 are provided, and the multiple pressurized air supply structures 310 are arranged at intervals along the extension direction of the ventilation interlayer 120. The partition structure 200 is provided with multiple air outlets 220 corresponding to the pressurized air supply structures 310.

[0065] By setting up multiple pressurized air supply structures 310 and arranging them at intervals along the extension direction of the ventilation interlayer 120, and configuring multiple corresponding air outlets 220 on the partition structure 200, the uniform distribution and efficient delivery of airflow in the clean corridor 130 are achieved.

[0066] Furthermore, this multi-point air supply configuration can effectively avoid the problem of uneven air volume that may be caused by a single air supply structure, ensuring that each sub-room 110 can obtain a stable and sufficient supply of clean air.

[0067] In addition, the spaced pressurized air supply structure 310 can shorten the air delivery path, reduce pressure loss and energy consumption caused by long-distance delivery, thereby further improving the operating efficiency and energy-saving performance of the entire mushroom house ventilation system, and providing a more balanced and stable environmental condition for mushroom growth.

[0068] In the embodiments of this utility model, such as Figure 2 and Figure 3In the embodiment shown, the conveying structure 320 includes a plurality of second centrifugal fans 321 for connecting the clean corridor 130 with each sub-room 110, the second centrifugal fans 321 being used to convey air in the clean corridor 130 to the corresponding sub-room 110.

[0069] By installing a second centrifugal fan 321 to connect the clean corridor 130 with each sub-room 110, efficient distribution and precise delivery of clean air are achieved. Each second centrifugal fan 321 is independently responsible for delivering air from the clean corridor 130 to the corresponding sub-room 110, thereby ensuring that the air quality and environmental parameters in each sub-room 110 meet the growth requirements of mushrooms.

[0070] Furthermore, by controlling the second centrifugal fan 321, the air volume and airflow speed of each sub-chamber 110 can be flexibly adjusted according to actual needs, further improving the adaptability and controllability of the system.

[0071] Designers may adjust the specific model and structure of the second centrifugal fan 321 according to usage requirements, and no specific restrictions are imposed here. In one specific embodiment, the second centrifugal fan 321 is a wall-mounted centrifugal fan.

[0072] Furthermore, such as Figure 2 In the embodiment shown, at least two second centrifugal fans 321 are provided on the inner wall corresponding to each sub-room 110.

[0073] By installing at least two second centrifugal fans 321 on the inner wall corresponding to each sub-room 110, the uniformity of clean air distribution and delivery efficiency within the sub-room 110 are further optimized.

[0074] The configuration of multiple second centrifugal fans 321 can effectively avoid the airflow dead zone problem that may be caused by a single fan, and ensure that clean air can fully cover all areas of the sub-room 110, thereby providing a more balanced and stable environmental condition for mushroom growth.

[0075] In addition, this multi-fan layout enhances the redundancy of the system. Even if one fan fails, the other fans can still maintain the basic ventilation needs of the sub-room 110, improving the reliability and stability of the entire mushroom house ventilation system, while also facilitating later maintenance and upgrades.

[0076] In this embodiment of the invention, the outlet of the second centrifugal fan 321 is provided with an adjustable-angle air outlet 322. By providing an adjustable-angle air outlet 322, the flexibility and precision of airflow delivery are further improved.

[0077] By adjusting the angle of the air outlet 322, the airflow direction and coverage can be optimized, effectively avoiding dead air zones or direct blowing on the mushrooms caused by airflow in a single fixed direction. This ensures that clean air is evenly distributed in the sub-room 110, providing a more stable environmental condition for mushroom growth.

[0078] In addition, the adjustable air outlet 322 can flexibly adjust the airflow intensity and coverage area according to the needs of different growth stages, reducing interference with the surface of the mushrooms and promoting their healthy development.

[0079] Furthermore, the adjustable-angle air outlet 322 enhances the system's adaptability, making it easier to handle sub-rooms 110 of different sizes and layouts, thus improving the overall ventilation system's versatility and ease of operation.

[0080] By setting a pressure difference between the clean corridor 130, the mushroom house 100 and the outside, for example, the clean corridor 130 is 5 Pa to 10 Pa higher than the outside and the sub-room 110 is 5 Pa to 10 Pa higher than the clean corridor 130, external pollutants are effectively prevented from entering, the cleanliness of the mushroom house 100 is maintained, and energy consumption is reduced.

[0081] This invention achieves the dual effects of efficient clean air delivery and stable pressure control by combining differential pressure control, significantly improving the accuracy and reliability of environmental regulation within the mushroom house 100.

[0082] Designers may adjust the specific structure of the air outlet 322 according to usage requirements, and no specific restrictions are imposed here. In one feasible embodiment, the air outlet 322 is a rotating air outlet.

[0083] By setting the air outlet 322 as a rotating air outlet, the flexibility and convenience of airflow direction adjustment are further improved. The rotating air outlet can adjust the airflow angle in real time according to actual needs, ensuring that clean air can evenly cover all areas within the mushroom house 100, avoiding uneven airflow or local eddies caused by fixed-direction air supply, thereby optimizing air distribution and improving the mixed-flow ventilation effect.

[0084] In the embodiments of this utility model, such as Figure 2 In the embodiment shown, each sub-room 110 has a pressure relief port 331 on its inner wall. The pressure relief structure 330 includes a plurality of first exhaust louvers 332 disposed on each pressure relief port 331 and a plurality of first differential pressure control valves 333 for communicating with each first exhaust louver 332. The first differential pressure control valves 333 are disposed in the sub-room 110 and located below the second centrifugal fan 321.

[0085] By setting pressure relief ports 331 on the inner wall of each sub-room 110, and forming a pressure relief structure 330 by the first exhaust louver 332 covering the pressure relief port 331 and the first differential pressure control valve 333, precise control of the internal pressure of the sub-room 110 can be achieved.

[0086] When the actual pressure in sub-chamber 110 exceeds the set value, the first differential pressure control valve 333 automatically opens, and the excess air is discharged through the first exhaust louver 332, thereby effectively preventing airflow turbulence or damage to the sealing of mushroom house 100 caused by excessive pressure.

[0087] In addition, placing the first differential pressure control valve 333 below the second centrifugal fan 321 not only optimizes the spatial layout but also reduces the interference of fan operation on the pressure relief process, ensuring the stability and reliability of the system.

[0088] In one feasible embodiment of this utility model, each sub-room 110 is provided with an exhaust vent 341 on its corresponding exterior wall. The exhaust structure 340 includes a plurality of second exhaust louvers 342 disposed on each exhaust vent 341 and a plurality of second differential pressure control valves 343 for communicating with each second exhaust louver 342. The second differential pressure control valves 343 are disposed in the sub-room 110 and located below the second centrifugal fan 321.

[0089] By setting an exhaust vent 341 on the exterior wall, and forming an exhaust structure 340 by a second exhaust louver 342 covering the exhaust vent 341 and a second differential pressure control valve 343, the pressure balance inside and outside the sub-room 110 and the orderly discharge of exhaust gas can be effectively achieved.

[0090] When the pressure inside sub-room 110 exceeds the set value or exhaust gas needs to be discharged, the second differential pressure control valve 343 automatically opens, and the excess air or exhaust gas is discharged to the outside through the second exhaust louver 342. This avoids the impact of excessive pressure on the growth of mushrooms due to airflow turbulence or exhaust gas retention, and helps to maintain the clean pressure difference and air quality inside mushroom house 100, ensuring the stability and cleanliness of the mushroom growth environment.

[0091] Furthermore, placing the second differential pressure control valve 343 below the second centrifugal fan 321 optimizes the spatial layout and reduces the interference of fan operation on the exhaust process, ensuring the stability and reliability of the system.

[0092] In another feasible embodiment of this utility model, each sub-room 110 is provided with an exhaust vent 341 on its corresponding exterior wall, and the exhaust structure 340 includes a plurality of exhaust devices installed on each exhaust vent 341.

[0093] By installing an exhaust vent 341 on the exterior wall and an exhaust device on the exhaust vent 341, the efficiency of orderly air discharge in the sub-room 110 can be significantly improved by using the exhaust device.

[0094] Furthermore, the exhaust system can effectively remove waste gas and excess heat from the sub-chamber 110, preventing waste gas from accumulating and adversely affecting mushroom growth, while also preventing excessive pressure from causing airflow disturbances or damage to the seal.

[0095] Operators can flexibly adjust the exhaust volume according to actual needs to ensure that the pressure in sub-room 110 is stable within the set range, maintain a good mixed-flow ventilation effect, thereby optimizing the air quality in mushroom house 100, improving the adaptability and energy-saving effect of the entire ventilation system, and providing a more stable environmental condition for mushroom growth.

[0096] Designers may adjust the specific structure of the exhaust device according to usage requirements, and no specific limitations are imposed here. In one feasible embodiment, the exhaust device is a wall-mounted exhaust fan.

[0097] Of course, in other feasible implementations, the designer may also set the exhaust port as a power exhaust port 341, without making specific restrictions here.

[0098] In the embodiments of this utility model, such as Figure 2 In the embodiment shown, the mushroom house ventilation system also includes an insect-proof net 400, which is installed on the outside of the mushroom house 100 and covers the exhaust vent 341.

[0099] By installing an insect-proof net 400 on the outside of the exhaust vent 341 of the mushroom house 100, external insects can be effectively prevented from entering the mushroom house 100 through the exhaust vent 341, thereby avoiding harm or contamination to the mushroom growth caused by insects. Furthermore, the installation of the insect-proof net 400 does not significantly affect the exhaust efficiency, ensuring both the normal operation of the ventilation system and maintaining the cleanliness and biosafety within the mushroom house 100.

[0100] In the embodiments of this utility model, such as Figure 2 In the embodiment shown, the mushroom house 100 is stacked in multiple layers, and each layer of the mushroom house 100 is provided with an independent partition structure 200 and a ventilation mechanism 300.

[0101] By stacking the mushroom houses 100 into multiple layers and configuring each layer of mushroom houses 100 with an independent partition structure 200 and ventilation mechanism 300, the space utilization rate and environmental control precision can be significantly improved. It also enables the independent operation of each layer of mushroom houses 100, avoiding cross-contamination of airflow or pressure interference between different layers. This ensures that key parameters such as temperature, humidity, pressure difference and air quality in each layer of mushroom houses 100 can be precisely controlled according to specific needs.

[0102] In addition, the independent partition structure 200 and ventilation mechanism 300 allow each layer of mushroom house 100 to flexibly adapt to the growth requirements of different mushroom varieties, improving the versatility and production efficiency of the system, while reducing energy consumption and operation and maintenance costs, providing a reliable guarantee for efficient and stable mushroom cultivation.
