Description

Technical Field

[0001] This application belongs to the field of edible fungi cultivation environment purification technology, and in particular refers to a series air sterilizer applied to a mushroom growing room. Background Technology

[0002] The mushroom growing room is the core place for cultivating edible fungi (such as shiitake mushrooms and enoki mushrooms). Its function is to support the growth of the spawn bags and produce fruiting products. The environment is characterized by high humidity (relative humidity 80%-95%RH). This environment is suitable for the growth of mushrooms, but it is also prone to the growth of miscellaneous bacteria. Therefore, it is necessary to continuously supply fresh air to meet the respiration needs of the mushrooms, while strictly controlling the concentration of miscellaneous bacteria (≤100cfu / m³) to avoid contamination of the spawn bags. This is a key link in the large-scale production of edible fungi. Given the characteristics of the mushroom growing room environment, contamination by miscellaneous bacteria can easily lead to a reduction in mushroom bag yield of more than 30%. Therefore, specialized air sterilization equipment is required, and the equipment must take into account both ventilation efficiency and the absence of chemical residues to meet the safety requirements for mushroom growth.

[0003] Currently, most mushroom growing rooms rely on a single sterilization device, which results in incomplete sterilization. Utility Model Content

[0004] Therefore, the technical problem to be solved by this application is to improve the problem of incomplete sterilization in the existing mushroom growing room.

[0005] To address the aforementioned technical problems, this application provides a series-connected air sterilizer for mushroom growing rooms, comprising multiple sterilization chambers arranged sequentially. The first-stage sterilization chamber has an air inlet, and the last-stage sterilization chamber has a sterile air outlet. Adjacent sterilization chambers are alternately connected by connecting pipes. Each sterilization chamber contains several horizontal partitions, which are staggered vertically to form a continuous S-shaped channel. Each sterilization chamber is equipped with an ultraviolet sterilization lamp, and each sterilization chamber contains an inclined filter plate. The filter plate divides the space of the corresponding sterilization chamber. After passing through the filter plate, the air enters the next sterilization chamber through the connecting pipe. After passing through the final filter plate, the air enters the mushroom growing room through the sterile air outlet.

[0006] By adopting the above technical solutions, the continuous S-shaped channel can extend the residence time of air in the chamber, improving the problems of fast airflow and insufficient sterilization; the inclined filter plate ensures that the airflow must pass through the filter plate for purification; the ultraviolet germicidal lamp and the filter plate work together to form a dual protection of ultraviolet disinfection and physical interception, initially controlling the concentration of miscellaneous bacteria in the mushroom house and adapting to the sterile air requirements of mushroom growth.

[0007] Preferably, there are four multi-stage sterilization boxes, namely a first sterilization box, a second sterilization box, a third sterilization box, and a fourth sterilization box; the top of the first sterilization box is connected to the top of the second sterilization box, the bottom of the second sterilization box is connected to the bottom of the third sterilization box, and the top of the third sterilization box is connected to the top of the fourth sterilization box.

[0008] By adopting the above technical solutions, the alternating airflow path from top to bottom can extend the airflow detour distance and improve the contact efficiency between the airflow and the sterilization components; the graded design of the sterilization box matches the progressive purification needs of the mushroom house, avoiding insufficient inactivation of stubborn bacteria by single-stage sterilization.

[0009] Preferably, the filter plate includes an alcohol filter plate disposed at the top of the first sterilization box, a potassium permanganate filter plate disposed at the bottom of the second sterilization box, an acetic acid sterilization filter plate disposed at the top of the third sterilization box, and a fiber cotton filter plate disposed at the bottom of the fourth sterilization box.

[0010] By adopting the above technical solutions, alcohol, potassium permanganate, and acetic acid sterilization filter plates chemically inhibit common miscellaneous bacteria (Trichoderma, Penicillium, Alternaria) in the mushroom growing room, while fiber cotton filter plates ultimately intercept residual particles, forming a combination of chemical targeted antibacterial and physical final filtration protection. Moreover, the chemical reagents are mild and leave no residue, and do not affect the growth of mushrooms. The filter plates are oriented towards the corresponding connecting pipes and sterile air outlets to ensure that the airflow passes directly through the filter plates without any filtration blind spots, preventing unfiltered air from seeping into the next sterilization box or mushroom growing room through gaps.

[0011] Preferably, ultraviolet germicidal lamps are installed under each partition in the first and third sterilization boxes, and ultraviolet germicidal lamps are also installed on the top inner wall of the second and fourth sterilization boxes. Except for the bottom partition, ultraviolet germicidal lamps are also installed under the other partitions in the second and fourth sterilization boxes.

[0012] By adopting the above technical solution, a potassium permanganate filter plate is installed at the bottom of the second sterilization box, and a fiber cotton filter plate is installed at the bottom of the fourth sterilization box. No light is installed under the bottom partition, which can avoid the failure of the filter plate due to long-term ultraviolet radiation. For example, potassium permanganate is prone to component decomposition under ultraviolet radiation, reducing the chemical antibacterial effect on miscellaneous bacteria in the fruiting room; long-term ultraviolet radiation will accelerate the aging of the fiber cotton material, shorten the filter life, and thus affect the air cleanliness of the fruiting room. Lights are installed under the partitions in the first and third sterilization boxes, and lights are installed on the top and under the partitions of the second and fourth sterilization boxes, ensuring that there are no blind spots in the key disinfection areas in the continuous S-shaped channel. This achieves sufficient ultraviolet inactivation of the air in the fruiting room, protects the function of the bottom filter plate, and maintains the long-term stable purification efficiency of the equipment.

[0013] Preferably, the filter plate is inclined at an angle of 15°-45° to the inner wall of the corresponding sterilization chamber, and its edge is sealed to the inner wall of the corresponding sterilization chamber.

[0014] By adopting the above technical solution, the 15°-45° tilt angle can increase the contact area between air and filter plate, thereby improving filtration efficiency. At the same time, it allows condensate to flow down the plate, preventing the filter plate from becoming damp and moldy for a long time and maintaining filtration performance. The edge sealing connection prevents unfiltered air from leaking from the gap between the plate and the box wall, ensuring that every part of the airflow is filtered and guaranteeing the cleanliness of the air entering the mushroom house.

[0015] Preferably, both ends of the connecting pipe are connected to the corresponding sterilization box via sealing flanges, and the inlet end of the connecting pipe is opposite to the output end of the corresponding filter plate.

[0016] By adopting the above technical solution, the sealing flange eliminates air leakage at the connection pipe interface, preventing unpurified air containing bacteria and dust from seeping into the mushroom house and preventing secondary pollution; the inlet end of the connection pipe corresponds to the output end of the filter plate, so that the airflow flows directly into the connection pipe after flowing out of the filter plate, without eddy current loss, maintaining the ventilation required by the mushroom house (mushrooms need a continuous supply of fresh air to breathe), and balancing sterilization efficiency and ventilation requirements.

[0017] Preferably, the air inlet of the first sterilization chamber is lower than the bottom horizontal partition inside the chamber, and the sterile air outlet of the fourth sterilization chamber is located on the side wall below the bottom partition inside the chamber.

[0018] By adopting the above technical solution, the inlet of the first sterilization box is lower than the bottom partition, which forces the air to enter from the bottom and flow upward along the continuous S-shaped channel, ensuring the sterilization path of the air in the first sterilization box; the outlet of the fourth sterilization box is below the bottom partition, so that the air can enter the fourth sterilization box through the connecting pipe, pass through the complete sterilization channel, and then enter the mushroom house through the sterile air outlet at the bottom, further ensuring the sterilization effect of the air in the fourth sterilization box.

[0019] Preferably, the ultraviolet germicidal lamps are equidistantly distributed along the vertical direction.

[0020] By adopting the above technical solution, the equidistant distribution ensures that the ultraviolet intensity of each section of the continuous S-shaped channel is consistent, avoiding situations where local irradiation is insufficient, such as weak disinfection in the middle of the channel and strong disinfection at both ends. This ensures that suspended bacteria in the airflow can be effectively inactivated at any position in the channel, preventing contamination of the bacterial bags due to uneven disinfection.

[0021] Preferably, the ultraviolet germicidal lamp is detachably connected to the corresponding partition or the inner wall of the sterilization chamber via an installation structure.

[0022] By adopting the above technical solutions, the detachable design facilitates the regular replacement of aging ultraviolet germicidal lamps in the mushroom growing room (the lifespan of the lamp body is shortened in high humidity environments), reduces equipment downtime for maintenance, and ensures the continuity of air purification in the mushroom growing room.

[0023] Preferably, the installation structure includes a strip-shaped mounting base, a retaining strip is fixedly provided on the top of the ultraviolet germicidal lamp, and a retaining groove adapted to the retaining strip is opened at the bottom of the mounting base. Elastic buckles are provided on both sides of the retaining groove. The retaining strip can be engaged in the retaining groove and is detachably connected to the mounting base through the elastic buckles. The mounting base is bolted to the lower surface of the partition or the inner wall of the top of the sterilization box.

[0024] The locking strip and slot work together to achieve precise positioning of the ultraviolet germicidal lamp, avoiding lamp body displacement and resulting in deviation of the irradiation angle, and ensuring a continuous S-shaped channel of ultraviolet coverage; the elastic buckle facilitates quick disassembly and assembly, reducing maintenance difficulty.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. Highly efficient and synergistic sterilization, precise control of miscellaneous bacteria in the mushroom growing room: Through the combination design of multi-stage sterilization boxes in series, continuous S-shaped channels to extend contact time, and the synergistic effect of ultraviolet light and targeted filter plates, a triple protection of physical interception, ultraviolet disinfection and chemical targeted antibacterial is formed, which can stably control the concentration of miscellaneous bacteria in the air of the mushroom growing room, effectively solve the problem of easy growth of miscellaneous bacteria in high humidity environment and the insufficient effect of single sterilization method, and significantly reduce the risk of contamination of mushroom bags; 2. Strong structural adaptability, suitable for the special environment of the mushroom house: The inclined filter plate is precisely aligned with the connecting pipe and the sterile air outlet, the airflow path is alternately connected at the top and bottom, and the design of not installing ultraviolet sterilization lamps under the bottom partition ensures that the air is purified without blind spots throughout the entire path, avoids the damage of ultraviolet light to the performance of the bottom potassium permanganate filter plate and fiber cotton filter plate, and reduces the impact of condensation on the equipment in high humidity environment, balancing sterilization efficiency and ventilation requirements of the mushroom house; 3. Convenient maintenance and long-term stability: The ultraviolet germicidal lamp is designed with a combination of clips and slots and elastic buckles, which allows for detachable installation, making it easy to quickly replace aging lamps and reduce downtime for maintenance.

Detailed Implementation

[0028] The present application will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present application, but the embodiments are not intended to limit the present application.

[0029] Reference Figures 1 to 4 As shown, this application discloses a series-connected air sterilizer for use in a mushroom growing room, comprising a first sterilization box 1, a second sterilization box 2, a third sterilization box 3, and a fourth sterilization box 4 arranged sequentially. The first sterilization box 1 has an air inlet 11 on the side away from the second sterilization box 2, and an exhaust fan is installed at the air inlet 11. The fourth sterilization box 4 has a sterile air outlet 41 on the side away from the third sterilization box 3, and the fourth sterilization box 4 is connected to the inside of the mushroom growing room through the sterile air outlet 41. The top of the side wall of the first sterilization box 1 and the top of the side wall of the second sterilization box 2 are connected to each other through a connecting pipe 5. The bottom of the side wall of the second sterilization box 2 and the bottom of the side wall of the third sterilization box 3 are also connected to each other through a connecting pipe 5. The top of the side wall of the third sterilization box 3 and the top of the side wall of the fourth sterilization box 4 are also connected to each other through a connecting pipe 5.

[0030] During operation, the exhaust fan draws air into the first sterilization chamber 1. The air enters the first sterilization chamber 1 through the air inlet 11 and undergoes staged sterilization in sequence through the first sterilization chamber 1, the second sterilization chamber 2, the third sterilization chamber 3, and the fourth sterilization chamber 4. After sterilization, the air enters the mushroom growing room through the sterile air outlet 41. Preferably, an FFU fan filter unit is also installed at the air inlet 11 to improve the cleanliness of the airflow.

[0031] Reference Figure 1 and Figure 2 Each of the first sterilization chamber 1, the second sterilization chamber 2, the third sterilization chamber 3, and the fourth sterilization chamber 4 is equipped with several partitions 6; refer to Figure 2 and Figure 3Each partition 6 is horizontally arranged, with one end fixedly connected to the inner wall of one side of the corresponding sterilization chamber, and the other end extending towards the inner wall of the other side of the sterilization chamber without contacting it. The other two ends of the partition 6 are also fixedly connected to the inner walls of the other two sides of the sterilization chamber, respectively. The non-contact ends of adjacent partitions 6 face the inner walls of opposite sides of the sterilization chamber, so that the partitions 6 are staggered in the vertical direction, thereby forming multiple continuous S-shaped bends in the sterilization chamber. The continuous S-shaped channels can prolong the residence time of air in the sterilization chamber, making sterilization more thorough.

[0032] Reference Figure 2 The air inlet 11 of the first sterilization chamber 1 is lower than the bottom horizontal partition 6 inside the chamber, and the sterile air outlet 41 of the fourth sterilization chamber 4 is located on the side wall below the bottom partition 6 inside the chamber. The positions of the air inlet 11, the sterile air outlet 41 and the corresponding connecting pipe 5 are staggered, so that the air can pass through a complete sterilization path in each sterilization chamber, ensuring the sterilization effect.

[0033] During operation, air enters the first sterilization chamber 1 from the bottom through air inlet 11 and flows upward along a continuous S-shaped channel. Then, it enters the second sterilization chamber 2 from the top through the first connecting pipe 5. After entering the second sterilization chamber 2, it flows downward along a continuous S-shaped channel. Then, it enters the third sterilization chamber 3 from the bottom through the second connecting pipe 5. After entering the third sterilization chamber 3, it flows upward along a continuous S-shaped channel. Then, it enters the fourth sterilization chamber 4 from the top through the third connecting pipe 5. Finally, it enters the mushroom growing room from the top of the fourth sterilization chamber 4 through a continuous S-shaped sterilization channel and then through the sterile air outlet 41 at the bottom.

[0034] Reference Figure 2 The first sterilization chamber 1 is equipped with an alcohol filter plate 12 at the top, the second sterilization chamber 2 with a potassium permanganate filter plate 21 at the bottom, the third sterilization chamber 3 with an acetic acid sterilization filter plate 31 at the top, and the fourth sterilization chamber 4 with a fiber cotton filter plate 42 at the bottom. The alcohol filter plate 12 faces the first connecting pipe 5, the potassium permanganate filter plate 21 faces the second connecting pipe 5, the acetic acid sterilization filter plate 31 faces the third connecting pipe 5, and the fiber cotton filter plate 42 faces the sterile air outlet 41. The alcohol, potassium permanganate, and acetic acid sterilization filter plates 31 can chemically inhibit common miscellaneous bacteria in the fruiting room, such as Trichoderma, Penicillium, and Alternaria. The filter plates face the corresponding connecting pipes 5 and sterile air outlet 41 to ensure that the airflow passes directly through the filter plates without any filtration blind spots, preventing unfiltered air from seeping into the next sterilization chamber or the fruiting room through gaps.

[0035] During operation, air enters the first sterilization chamber 1, is filtered by the alcohol filter plate 12, then enters the second sterilization chamber 2, is filtered by the potassium permanganate filter plate 21, enters the third sterilization chamber 3, is filtered by the acetic acid sterilization filter plate 31, enters the fourth sterilization chamber 4, and is filtered by the fiber cotton filter plate 42 before entering the mushroom growing room.

[0036] Reference Figure 2 In the first sterilization chamber 1 and the third sterilization chamber 3, a set of ultraviolet (UV) germicidal lamps 7 are installed on the lower surface of each partition 6. Similarly, UV germicidal lamps 7 are installed on the inner top wall of the second sterilization chamber 2 and the fourth sterilization chamber 4. Furthermore, UV germicidal lamps 7 are also installed on the lower surface of all partitions 6 in the second and fourth sterilization chambers 2 and 4, except for the bottom partition 6. The UV germicidal lamps 7 in each sterilization chamber are equidistantly distributed vertically. This equidistant distribution ensures consistent UV intensity across the continuous S-shaped channel, preventing insufficient local irradiation (e.g., weak disinfection in the middle of the channel and strong disinfection at both ends). This ensures that suspended bacteria in the airflow are effectively inactivated at any point in the channel, preventing contamination of the mushroom bags due to uneven disinfection. The UV germicidal lamps 7 and the filter plates work together to form a dual protection of UV disinfection and physical interception, initially controlling the concentration of bacteria in the mushroom house and meeting the sterile air requirements for mushroom growth.

[0037] The second sterilization chamber 2 has a potassium permanganate filter plate 21 at the bottom, and the fourth sterilization chamber 4 has a fiber cotton filter plate 42 at the bottom. No ultraviolet (UV) sterilization lamp 7 is installed under the bottom partition 6 to avoid long-term UV exposure causing filter plate performance failure. For example, potassium permanganate is prone to component decomposition under UV radiation, reducing its chemical antibacterial effect against miscellaneous bacteria in the fruiting room; long-term UV exposure to fiber cotton will accelerate material aging, shorten filter life, and thus affect the air cleanliness of the fruiting room. UV sterilization lamps 7 are installed under the partition 6 of the first and third sterilization chambers, and on the top and non-bottom partition 6 of the second and fourth sterilization chambers. This ensures that there are no blind spots in the key disinfection areas within the continuous S-shaped channel, achieving sufficient UV inactivation of the air in the fruiting room while protecting the function of the bottom filter plate and maintaining the long-term stable purification efficiency of the equipment.

[0038] During operation, air enters the first sterilization chamber 1 through air inlet 11, is sterilized by ultraviolet germicidal lamps 7 with a continuous S-shaped channel, and then passes through an alcohol filter plate 12 for a first filtration before entering the second sterilization chamber 2. In the second sterilization chamber 2, it is sterilized by ultraviolet germicidal lamps 7 with a continuous S-shaped channel, and then passes through a potassium permanganate filter plate 21 for a second filtration before entering the third sterilization chamber 3. In the third sterilization chamber 3, it is sterilized by ultraviolet germicidal lamps 7 with a continuous S-shaped channel, and then passes through an acetic acid sterilization filter plate 31 for a third filtration before entering the fourth sterilization chamber 4. In the fourth sterilization chamber 4, it is sterilized by ultraviolet germicidal lamps 7 with a continuous S-shaped channel, and finally passes through a fiber cotton filter plate 42 before entering the mushroom growing room.

[0039] Reference Figure 2The tilt angles of the alcohol filter plate 12 with the inner wall of the first sterilization chamber 1, the potassium permanganate filter plate 21 with the inner wall of the second sterilization chamber 2, the acetic acid sterilization filter plate 31 with the inner wall of the third sterilization chamber 3, and the fiber cotton filter plate 42 with the inner wall of the fourth sterilization chamber 4 are all between 15° and 45°, and the edge of each filter plate is sealed to the inner wall of the corresponding sterilization chamber. Setting the tilt angles between 15° and 45° increases the contact area between air and the filter plate, thereby improving filtration efficiency. Simultaneously, it allows condensate to flow down the plate, preventing the filter plate from becoming damp and moldy over a long period, thus maintaining filtration performance. The sealed edge connection prevents unfiltered air from leaking through the gaps between the plate and the chamber wall, ensuring that every part of the airflow is filtered and guaranteeing the cleanliness of the air entering the mushroom growing room.

[0040] Preferably, both ends of each connecting pipe 5 are connected to the corresponding sterilization chamber via sealing flanges, with the inlet end of the connecting pipe 5 facing the outlet end of the corresponding filter plate. The sealing flanges prevent air leakage at the interface of the connecting pipe 5, avoiding the infiltration of unpurified air containing bacteria and dust from outside the fruiting house, thus preventing secondary pollution. The inlet end of the connecting pipe 5 corresponds to the outlet end of the filter plate, allowing airflow to directly enter the connecting pipe 5 after flowing out of the filter plate, without eddy current loss, maintaining the required ventilation volume of the fruiting house, and balancing sterilization efficiency and ventilation requirements.

[0041] Reference Figure 4 The ultraviolet germicidal lamp 7 is detachably connected to the corresponding partition 6 or the inner wall of the sterilization box via the installation structure 8. The installation position covers the lower surface of the partition 6 inside the first sterilization box 1 and the third sterilization box 3, the top of the second sterilization box 2 and the fourth sterilization box 4, and the lower surface of the non-bottom partition 6 inside the second sterilization box 2 and the fourth sterilization box 4, ensuring that the ultraviolet lamp is accurately installed in the key sterilization area without blind spots. The detachable design facilitates the regular replacement of aging ultraviolet lamps in the mushroom house (the lamp life is shortened in high humidity environments), reducing equipment downtime for maintenance and ensuring the continuity of air purification in the mushroom house.

[0042] Reference Figure 1 Each of the first sterilization chamber 1, the second sterilization chamber 2, the third sterilization chamber 3, and the fourth sterilization chamber 4 has an operating door on one outer side wall for operating within the sterilization chamber. (Refer to...) Figure 2 and Figure 4 The mounting structure 8 includes a strip-shaped mounting base 81. A retaining strip 82 is fixedly mounted on the top of the ultraviolet germicidal lamp 7. The bottom of the mounting base 81 has a groove 811 that matches the retaining strip 82. Elastic buckles 812 are located on both sides of the groove 811. The retaining strip 82 can be engaged within the groove 811 and is detachably connected to the mounting base 81 via the elastic buckles 812. The mounting base 81 is fixed to the lower surface of the partition 6 or the inner wall of the top of the sterilization chamber by bolts. The retaining strip 82 and the groove 811 work together to achieve precise positioning of the ultraviolet lamp, preventing lamp displacement and ensuring UV coverage of the S-shaped channel. The elastic buckles 812 facilitate quick assembly and disassembly, reducing maintenance difficulty.

[0043] The implementation principle of this application embodiment is as follows: Air enters the first sterilization chamber 1 from the bottom through air inlet 11 and flows upward along a continuous S-shaped channel. It undergoes primary sterilization under the action of ultraviolet germicidal lamp 7 within the first continuous S-shaped channel. Then, it passes through alcohol filter plate 12 for primary filtration and enters the top of the second sterilization chamber 2 through the first connecting pipe 5. After entering the second sterilization chamber 2, air flows downward along a continuous S-shaped channel. It undergoes secondary sterilization under the action of ultraviolet germicidal lamp 7 within the second continuous S-shaped channel. Then, it passes through potassium permanganate filter plate 21 for secondary filtration and enters the second sterilization chamber 2 through... The second connecting pipe 5 enters the bottom of the third sterilization chamber 3; after entering the third sterilization chamber 3, the air flows upward along the continuous S-shaped channel, and is sterilized three times under the action of the ultraviolet sterilization lamp 7 in the third continuous S-shaped channel. Then, after being filtered three times by the acetic acid sterilization filter plate 31, it enters the top of the fourth sterilization chamber 4 through the third connecting pipe 5; finally, it flows downward from the top of the fourth sterilization chamber 4, and is sterilized for the last time under the action of the ultraviolet sterilization lamp 7 in the fourth continuous S-shaped channel. Finally, after being filtered by the fiber cotton filter plate 42, it enters the mushroom growing room through the sterile air outlet 41 at the bottom.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
