Abstract
Description
Technical Field
[0001] This utility model relates to the field of matsutake mushroom bed disinfection technology, specifically to an ultraviolet irradiation device for disinfecting matsutake mushroom beds. Background Technology
[0002] Disinfection of matsutake mushroom beds is a crucial step in the cultivation process, typically employing a combination of physical and chemical methods: first, high-pressure steam sterilization (121℃, 30 minutes) or ultraviolet irradiation (253.7nm, 30-60 minutes) kills unwanted bacteria and insect eggs; then, a low-toxicity disinfectant (such as 3% hydrogen peroxide or ozone water) is sprayed onto the surface. After disinfection, ventilation for 24 hours is required to eliminate residues, and inoculation can only proceed after the sterility rate of the mushroom bed is tested to be ≥99%. The entire process must be carried out in a closed, clean environment to ensure that the activity of the matsutake mycelium and subsequent growth are not affected.
[0003] In practical applications, most ultraviolet (UV) irradiation devices used for disinfecting matsutake mushroom beds employ a fixed irradiation design, which presents several potential drawbacks affecting disinfection effectiveness. Firstly, due to the limited penetrating power of UV light, the radiation dose received by different areas of the mushroom bed surface is uneven in static irradiation mode. Areas near the lamp may experience excessive irradiation, affecting mycelial activity, while edges or recessed areas may suffer from insufficient irradiation, creating sterilization dead zones. Secondly, the mushroom bed substrate typically has a three-dimensional structure, and pathogenic microorganisms can easily remain on unirradiated sides and the bottom layer, especially when the bed thickness exceeds 5 cm, making it difficult for UV light to effectively cover the entire cross-section. Furthermore, long-term fixed-angle irradiation can cause localized material (such as wood fibers) to degrade due to continuous exposure to high-energy UV light, creating conditions conducive to the growth of other microorganisms. Additionally, if the ozone accumulated during disinfection cannot diffuse evenly, it may form high-concentration areas in localized parts of the mushroom bed, inhibiting subsequent mycelial colonization. The combined effect of these factors significantly reduces overall disinfection efficiency and may increase the number of repeated disinfection cycles, ultimately affecting the yield and quality stability of matsutake mushrooms.
[0004] To address the aforementioned issues, we have made improvements by proposing an ultraviolet irradiation device for disinfecting matsutake mushroom beds. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an ultraviolet irradiation device for disinfecting matsutake mushroom beds, comprising a base plate, an irradiation box fixedly connected to the top of the base plate, a purification chamber and an irradiation chamber respectively opened on the top and bottom of the inner surface of the irradiation box, a first turntable movably connected to the left side of the inner cavity of the irradiation chamber, and a second turntable movably connected to the right side of the inner cavity of the irradiation chamber, threaded rods threadedly connected to the top and bottom of the inner sides of the first and second turntables, a clamping plate movably connected to the inner side of the threaded rod, an anti-slip pad bonded to the inner side of the clamping plate, and a handwheel fixedly connected to the outer side of the threaded rod.
[0006] Preferably, a servo motor for driving the first turntable to rotate is fixedly connected to the left side of the irradiation box. The output end of the servo motor extends into the inner cavity of the irradiation chamber and is fixedly connected to the middle of the left side of the first turntable.
[0007] Preferably, the inner surface of the irradiation box and the left and right sides of the inner wall of the irradiation cavity are provided with annular sliding grooves, and the top and bottom of the outer sides of the first turntable and the second turntable are fixedly connected with sliding columns, and the outer sides of the sliding columns are slidably connected to the inner cavity of the annular sliding grooves.
[0008] Preferably, the top and bottom of the inner wall of the purification chamber are fixedly connected with a bracket, and there are three sets of brackets, with a purification filter screen being clamped into the inner cavity of each of the three sets of brackets.
[0009] Preferably, a ventilation mesh is embedded in the top left side of the irradiation box, a duct fan is fixedly connected to the right side of the inner cavity of the purification chamber, the input end of the duct fan is connected to a horn tube, the output end of the duct fan extends through to the right side of the irradiation box, an air inlet pipe is embedded in the left side of the inner wall of the irradiation box and located between the irradiation chamber and the purification chamber, and a sealing valve is provided on the surface of the air inlet pipe, and the irradiation chamber and the purification chamber are connected through the air inlet pipe.
[0010] Preferably, a fixing box is fixedly connected to the top of the irradiation cavity, and multiple evenly distributed ultraviolet germicidal lamps are fixedly connected to the inner cavity of the fixing box. A high-reflectivity aluminum film is adhered to the inner wall of the irradiation cavity.
[0011] Compared with the prior art, this utility model provides an ultraviolet irradiation device for disinfecting matsutake mushroom beds, which has the following beneficial effects:
[0012] 1. This ultraviolet irradiation device for disinfecting matsutake mushroom beds works by rotating a handwheel, which drives a threaded rod to rotate. The threaded rod moves inward using the thread, causing the clamping plate to move inward as well. This brings the inner side of the anti-slip mat into contact with the outer side of the mushroom bed, fixing the mushroom bed in place. Then, the output of the servo motor drives the first turntable to rotate. The first turntable, through the transmission of the threaded rod and the clamping plate, drives the mushroom bed to rotate, ensuring thorough irradiation of the mushroom bed and improving the disinfection effect and efficiency.
[0013] 2. This ultraviolet irradiation device for disinfecting matsutake mushroom beds effectively improves the stability of the first and second turntables during rotation by setting an annular chute and sliding column. Suction generated at the input end of the exhaust fan draws air from the irradiation chamber into the purification chamber through the air inlet pipe. The air undergoes multiple filtrations through a purification filter, preventing the diffusion of suspended microbial aerosols after ultraviolet sterilization and simultaneously decomposing ozone and dust particles generated by ultraviolet radiation. This ensures that the ozone concentration in the exhaust air is <0.05ppm. This dual filtration mechanism effectively prevents secondary biological and chemical pollution, guaranteeing the safety of the disinfection environment and the sterility of the mushroom bed. A mounting bracket allows for the disassembly and cleaning or replacement of the purification filter. The use of a high-reflectivity aluminum film effectively improves the utilization rate of ultraviolet radiation. Attached Figure Description

[0020] 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.
[0021] Please see Figure 1-4 An ultraviolet irradiation device for disinfecting matsutake mushroom beds includes a base plate 1. An irradiation box 2 is fixedly connected to the top of the base plate 1. A purification chamber 6 and an irradiation chamber 5 are respectively formed on the top and bottom of the inner surface of the irradiation box 2. A first turntable 7 is movably connected to the left side of the inner cavity of the irradiation chamber 5, and a second turntable 8 is movably connected to the right side of the inner cavity of the irradiation chamber 5. Threaded rods 19 are threadedly connected to the top and bottom of the inner sides of both the first turntable 7 and the second turntable 8. A clamping plate 20 is movably connected to the inner side of the threaded rod 19, and an anti-slip pad 21 is adhered to the inner side of the clamping plate 20. A handwheel 22 is fixedly connected to the outside of 9. A servo motor 4 for driving the first turntable 7 to rotate is fixedly connected to the left side of the irradiation box 2. The output end of the servo motor 4 passes through the inner cavity of the irradiation chamber 5 and is fixedly connected to the middle of the left side of the first turntable 7. Annular grooves 17 are provided on the inner surface of the irradiation box 2 and on both the left and right sides of the inner wall of the irradiation chamber 5. Sliding columns 18 are fixedly connected to the top and bottom of the outer sides of the first turntable 7 and the second turntable 8. The outer side of the sliding column 18 is slidably connected to the inner cavity of the annular groove 17.
[0022] Through the above technical solution, by rotating the handwheel 22, the handwheel 22 drives the threaded rod 19 to rotate. The threaded rod 19 moves inward using the action of the thread and drives the clamping plate 20 to move inward, so that the inner side of the anti-slip pad 21 contacts the outer side of the mushroom bed. After fixing the mushroom bed, the output end of the servo motor 4 drives the first turntable 7 to rotate. The first turntable 7 drives the mushroom bed to rotate through the transmission of the threaded rod 19 and the clamping plate 20, which can fully irradiate the mushroom bed and improve the disinfection effect and efficiency. By setting the annular groove 17 and the sliding column 18, the stability of the first turntable 7 and the second turntable 8 during the rotation process can be effectively improved.
[0023] Specifically, the top and bottom of the inner wall of the purification chamber 6 are fixedly connected with three sets of brackets 10, and the inner cavity of each of the three sets of brackets 10 is fitted with a purification filter 11. The top of the left side of the irradiation box 2 is inlaid with a ventilation net 3. The right side of the inner cavity of the purification chamber 6 is fixedly connected with a duct fan 12. The input end of the duct fan 12 is connected to a horn tube 13, and the output end of the duct fan 12 extends to the right side of the irradiation box 2. The left side of the inner wall of the irradiation box 2, located between the irradiation chamber 5 and the purification chamber 6, is inlaid with an air inlet pipe 14, and the surface of the air inlet pipe 14 is provided with a sealing valve. The irradiation chamber 5 and the purification chamber 6 are connected through the air inlet pipe 14. The top of the inner cavity of the irradiation chamber 5 is fixedly connected with a fixing box 15, and the inner cavity of the fixing box 15 is fixedly connected with multiple evenly distributed ultraviolet germicidal lamps 16. The inner wall of the irradiation chamber 5 is bonded with a high reflectivity aluminum film 9.
[0024] Through the above technical solution, the suction generated by the input end of the induced draft fan 12 draws the air from the inner cavity of the irradiation chamber 5 into the inner cavity of the purification chamber 6 through the air inlet pipe 14. The air undergoes multiple filtrations through the purification filter 11, blocking the diffusion of suspended microbial aerosols after ultraviolet sterilization, while decomposing the ozone and dust particles generated by ultraviolet light, ensuring that the ozone concentration in the discharged air is <0.05ppm. This dual filtration mechanism effectively prevents secondary biological and chemical pollution, ensuring the safety of the disinfection environment and the sterility of the bacterial bed. By setting the card holder 10, the purification filter 11 can be disassembled for cleaning or replacement. By setting the high reflectivity aluminum film 9, the utilization rate of ultraviolet light can be effectively improved.
[0025] In use, first turn the handwheel 22. The handwheel 22 drives the threaded rod 19 to rotate. The threaded rod 19 moves inward using the thread, which in turn moves the clamping plate 20 inward, so that the inner side of the anti-slip pad 21 contacts the outer side of the mushroom bed. After fixing the mushroom bed, the output end of the servo motor 4 drives the first turntable 7 to rotate. The first turntable 7 drives the mushroom bed to rotate through the transmission of the threaded rod 19 and the clamping plate 20, and fully irradiates the mushroom bed below through the fixing box 15, improving the disinfection effect and efficiency. After disinfection, the input end of the drainage fan 12 generates suction, which draws the irradiation chamber... Air from the inner cavity 5 is drawn into the inner cavity of the purification chamber 6 through the air inlet pipe 14. The air undergoes multiple filtrations through the purification filter 11, blocking the diffusion of suspended microbial aerosols after ultraviolet sterilization. At the same time, it decomposes the ozone generated by ultraviolet light and the dust particles it agitates, ensuring that the ozone concentration in the exhaust air is <0.05ppm. This dual filtration mechanism effectively prevents secondary biological and chemical pollution, ensuring the safety of the disinfection environment and the sterility of the bacterial bed.
