Description

Technical Field

[0001] This invention relates to the field of cereal mycotoxin degradation technology, specifically to a cereal mycotoxin degradation device based on plasma technology. Background Technology

[0002] Cereal fungi such as Fusarium graminearum can infect the ears, stems, stem bases, and roots of cereal crops such as wheat, barley, rice, and corn, causing diseases such as ear rot, stem rot, stem base rot, and root rot. They can also infect other plants. After grain harvest, it is necessary to degrade the toxins of fungi such as Fusarium graminearum to avoid affecting the processing and consumption of grains.

[0003] Commonly used chemical methods for degrading mycotoxins in grains cannot meet the demands for grain quality and safety. While plasma technology offers advantages such as minimal impact on food quality and no secondary residues, conventional plasma devices often result in uneven sample thickness and pitting when placed on the platen. This leads to inconsistent sample thickness and uneven processing, with thicker areas requiring longer processing times and inconsistent mycotoxin degradation rates across different regions. Therefore, we propose a plasma-based grain mycotoxin degradation device. Summary of the Invention

[0004] The purpose of this invention is to provide a cereal mycotoxin degradation device based on plasma technology to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cereal mycotoxin degradation device based on plasma technology, comprising a housing, a ventilation component, a discharge module, a support component, and a leveling component. The ventilation component for venting air into the housing includes an air pump and a gas mass flow controller. The air pump is located on the outside of the housing, and a fixing plate is fixed to the outside of the housing. The gas mass flow controller is fixed to the top of the fixing plate, and a connecting pipe is fixed to the output end of the air pump. The connecting pipe is fixed to the input end of the gas mass flow controller. An inlet pipe and an outlet pipe are fixed to the outside of the housing, and the output end of the gas mass flow controller is fixedly connected to the inlet pipe. The discharge module is installed on the top of the housing for discharge. The module consists of a replaceable high-voltage electrode plate. A high-frequency high-voltage plasma generator connected to the electrodes in the discharge module is fixed on the top of the box. An oscilloscope and a temperature and humidity display are fixed on the outside of the box. The oscilloscope is used to display the real-time voltage and current of the discharge module, which are collected by the high-voltage probe and the current probe, respectively. A support component for placing the sample to be processed is located inside the box. A leveling component for leveling the grains placed in the support component is located inside the box. By setting up the leveling component, this invention levels the grain samples on the support component, ensuring that the thickness of the grain samples is uniform, thereby ensuring the consistency of the processing effect of the grain samples after degradation treatment.

[0006] Preferably, the support assembly includes an electrically adjustable base and a placement plate that can clamp and limit the placement of a sample plate containing a grain sample. The electrically adjustable base is fixed to the bottom of the inner side of the chamber, and the placement plate is fixed to the top of the output end of the electrically adjustable base. This is used to adjust the distance between the grain sample on the placement plate and the discharge module, ensuring the degradation effect of grain mycotoxins.

[0007] Preferably, the leveling assembly includes a scraper and a drive motor. A rotating ring is rotatably mounted on the bottom inner side of the housing. Two support frames are symmetrically fixed on the top of the rotating ring. A mounting plate is fixed inside the support frame. An auxiliary frame is fixed on the side of the mounting plate near the placement plate. A mounting frame is installed inside the auxiliary frame. The two scrapers are fixed to the two mounting frames respectively by bolts. External teeth are evenly fixed on the outer side of the rotating ring. A gear that meshes with the external teeth is rotatably mounted on the bottom inner side of the housing. A support is fixed inside the housing. The drive motor is fixed on the top of the support. The output end of the drive motor is fixedly connected to the gear shaft. A storage assembly for storing the scrapers is provided inside the support frame. The rotating ring drives the support frame and the two scrapers to rotate around the placement plate. The grain sample on the placement plate is gradually leveled outward under the rotation of the scrapers, thereby ensuring that the thickness of the grain sample is uniform.

[0008] Preferably, the storage component includes a connecting rod, a storage motor and a first slider. A screw rod is rotatably provided at the top of the mounting plate. The top of the screw rod is rotatably connected to the inside of the support frame. The first slider is slidably disposed within the support frame. The screw rod is threadedly connected to the first slider. The storage motor is fixed to the bottom of the mounting plate. The output end of the storage motor penetrates through the mounting plate and is fixedly connected to the bottom of the screw rod. A first connecting seat is fixed to one side of the first slider close to the scraper. A second connecting seat is fixed to the outside of the mounting frame. Both ends of the connecting rod are rotatably connected to the first connecting seat and the second connecting seat respectively. The mounting frame is rotatably connected to the auxiliary frame. A vibration component for vibrating off the grains adhering to the scraper is provided at the top of the mounting plate, so as to store the scraper and prevent the scraper from affecting the up and down movement of the placing plate by the electric adjustment base.

[0009] Preferably, the vibration component includes a knocking block. A support plate is fixed to the outside of the mounting plate. A support is fixed to the top of the support plate. A fixing ring is fixed to the top of the support. A second slider is slidably disposed on the outside of the fixing ring. Compression springs are symmetrically sleeved on the outside of the fixing ring. One end of each compression spring is fixed to the support, and the other end is fixed to the second slider. The two compression springs are located on both sides of the second slider. The knocking block is fixed to the outside of the second slider. A vibration frame is fixed to the outside of the connecting rod, which can knock off the grains adhering to the scraper and prevent the grains remaining on the scraper from being carried into the next sample.

[0010] Preferably, the vibration frames are symmetrically fixed in a ring shape on the outside of the connecting rod. The vibration frames and the connecting rod form a Chinese character 'zhong', which can achieve secondary knocking on the connecting rod and the scraper.

[0011] Preferably, the length of the scraper is greater than the distance between the center of the auxiliary frame and the placing plate, so as to avoid the situation that the grain sample at the center of the placing plate cannot be flattened due to the short length of the scraper.

[0012] Preferably, the bottom of the scraper is provided with a bevel, which facilitates the smoother contact between the bottom of the scraper and the grains after the two scrapers are combined together.

[0013] Preferably, the height of the placing plate is greater than the height of the placing plate when the electric adjustment base is in the retracted state. By adjusting the height of the placing plate, the height of the bottom of the scraper from the placing plate can be adjusted, and further the thickness of the grain sample after being flattened can be adjusted.

[0014] Preferably, an automatic pressure relief valve is fixed to the outer end of the air outlet pipe. When the air supply component intakes air into the box body, the single-pass automatic pressure relief valve can discharge the excess gas in the box body to ensure the air pressure and airtight effect inside the box body.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention uses two scrapers, which are combined on a placement plate. The operation of a drive motor drives a gear to rotate, and the meshing of the gear with the external gear drives the rotating ring, support frame, mounting plate, auxiliary frame, mounting frame and scrapers to rotate synchronously. The scrapers flatten the thicker grain sample to the outside, thereby ensuring the uniformity of the grain sample thickness and the uniformity of the subsequent grain mycotoxin degradation effect.

[0017] 2. By setting the length of the scraper to be longer than the distance between the auxiliary frame and the center of the placement plate, the situation where the grain sample at the center of the placement plate cannot be flattened due to the scraper being too short can be avoided.

[0018] 3. The operation of the set storage motor drives the connecting rod to press and pull up the mounting frame with the scraper, so that the scraper can be stored in the support frame, ensuring unobstructed movement of the electric adjustment base to move the placement plate up and down.

[0019] 4. By setting a fixed ring with a compression spring, when the striking block contacts the outside of the vibration frame, the vibration frame squeezes the striking block as the connecting rod moves, causing the striking block and the second slider to move on the fixed ring and squeeze the compression spring. When the striking block moves out of the vibration frame, it returns to its initial position under the action of the compression spring, striking the connecting rod. The connecting rod receives the vibration, which is transmitted to the scraper by the mounting frame, knocking off the grains attached to the scraper. This prevents the grain residue on the scraper from being carried into the next sample. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0030] Please see Figures 1-8The diagram illustrates a plasma-based cereal mycotoxin degradation device, comprising a housing 1, a ventilation assembly 2, a discharge module 3, a support assembly 4, and a leveling assembly 5. The ventilation assembly 2, used to ventilate the housing 1, includes an air pump 6 and a gas mass flow controller 7. The air pump 6 is located on the outside of the housing 1, and a fixing plate 8 is fixed to the outside of the housing 1. The gas mass flow controller 7 is fixed to the top of the fixing plate 8. A connecting pipe 9 is fixed to the output end of the air pump 6, and the connecting pipe 9 is fixed to the input end of the gas mass flow controller 7. An inlet pipe 10 and an outlet pipe 11 are fixed to the outside of the housing 1. An automatic pressure relief valve 43 is fixed to the outer end of the outlet pipe 11. When the ventilation assembly 2 vents air into the housing 1, the one-way automatic pressure relief valve 43 can release excess gas from the housing 1, ensuring the internal air pressure and sealing effect of the housing 1. The output end of the gas mass flow controller 7 is fixedly connected to the inlet pipe 10. The discharge module 3 is installed on the top of the housing 1 and consists of a replaceable high-voltage electrode plate. The electrode structure consists of three parts: an uppermost high-voltage metal plate, a sandwiched polytetrafluoroethylene dielectric plate, and a grounding electrode composed of a hexagonal metal mesh at the bottom. A high-frequency high-voltage plasma generator 12 connected to the electrodes in the discharge module 3 is fixed on the top of the housing 1. An oscilloscope 13 and a temperature and humidity display 14 are fixed on the outside of the housing 1. The oscilloscope 13 is used to display the real-time voltage and current of the discharge module 3, which are collected by the high-voltage probe and the current probe, respectively. A support assembly 4 for placing the sample to be processed is located inside the housing 1. A leveling assembly 5 for leveling the grain placed inside the support assembly 4 is located inside the housing 1. The support assembly 4 includes an electric adjustment base 15 and a placement plate 16 that can clamp and limit the placement of the grain sample. The electric adjustment base 15 is fixed to the bottom of the inner side of the housing 1, and the placement plate 16 is fixed to the top of the output end of the electric adjustment base 15. It is used to adjust the distance between the grain sample on the placement plate 16 and the discharge module 3 to ensure the degradation effect of grain mycotoxins.

[0031] The following describes some embodiments of this application in detail with reference to the accompanying drawings:

[0032] Please see Figures 1-8 In this embodiment: by setting up the leveling component 5, the grain sample on the support component 4 is leveled to ensure that the thickness of the grain sample is consistent, thereby ensuring the consistency of the treatment effect of the grain sample after degradation treatment.

[0033] The leveling component 5 includes a scraper 17 and a drive motor 18. A rotating ring 19 is rotatably mounted on the bottom inner side of the housing 1. Two support frames 20 are symmetrically fixed to the top of the rotating ring 19. A mounting plate 21 is fixed inside the support frame 20. An auxiliary frame 22 is fixed to the side of the mounting plate 21 near the placement plate 16. A mounting frame 23 is installed inside the auxiliary frame 22. The two scrapers 17 are respectively fixed to the two mounting frames 23 by bolts. External teeth 24 are evenly fixed to the outer side of the rotating ring 19. A rotating ring 19 is rotatably mounted on the bottom inner side of the housing 1. There is a gear 25 that meshes with the external gear 24. A support 26 is fixed inside the housing 1. A drive motor 18 is fixed to the top of the support 26. The output end of the drive motor 18 is fixedly connected to the gear shaft of the gear 25. The support frame 20 is provided with a storage component 27 for storing the scraper 17. The support frame 20 and the two scrapers 17 are driven to rotate around the placement plate 16 by the rotating ring 19. The grain sample on the placement plate 16 is gradually flattened outward under the rotation of the scraper 17, thereby ensuring that the thickness of the grain sample is uniform.

[0034] Meanwhile, the storage component 27 includes a connecting rod 28, a storage motor 29, and a first slider 30. A screw 31 is rotatably provided on the top of the mounting plate 21, and the top of the screw 31 is rotatably connected to the inside of the support frame 20. The first slider 30 is slidably disposed in the support frame 20, and the screw 31 is threadedly connected to the first slider 30. The storage motor 29 is fixed to the bottom of the mounting plate 21, and the output end of the storage motor 29 passes through the mounting plate 21 and is connected and fixed to the bottom of the screw 31. A first connecting seat 32 is fixed on the side of the first slider 30 near the scraper 17. A second connecting seat 33 is fixed on the outside of the mounting frame 23. The two ends of the connecting rod 28 are rotatably connected to the first connecting seat 32 and the second connecting seat 33, respectively. The mounting frame 23 is rotatably connected to the auxiliary frame 22. The top of the mounting plate 21 is provided with a vibration component 34 for shaking off the grains attached to the scraper 17, which stores the scraper 17 and prevents the scraper 17 from affecting the electric adjustment base 15 to drive the placement plate 16 to move up and down.

[0035] Furthermore, the length of the scraper 17 is greater than the distance between the center of the auxiliary frame 22 and the center of the placement plate 16, so as to avoid the situation that the grain sample at the center of the placement plate 16 cannot be flattened due to the short length of the scraper 17. The bottom of the scraper 17 is provided with a bevel 42, so that the bottom of the scraper 17 can make the contact between the grain and the grain smoother after the two scrapers 17 are combined.

[0036] It is worth noting that, such as Figure 4 As shown, the height of the placement plate 16 is greater than the height of the placement plate 16 when the electric adjustment base 15 is in the retracted state. By adjusting the height of the placement plate 16, the distance between the bottom of the scraper 17 and the placement plate 16 can be adjusted, thereby adjusting the thickness of the grain sample after it is flattened.

[0037] Two scraping plates 17 are combined together on the placing plate 16, and then the operation of the driving motor 18 drives the gear 25 to rotate. Further, the rotation of the rotating ring 19, the support frame 20, the mounting plate 21, the auxiliary frame 22, the mounting frame 23 and the scraping plate 17 is driven by the meshing of the gear 25 and the external teeth 24. The thicker part of the grain sample is flattened outward by the scraping plate 17, so as to ensure the consistency of the thickness of the grain sample and the unity of the subsequent effect of grain mycotoxin degradation. By the operation of the storage motor 29 provided, the connecting rod 28 is driven to move, and the mounting frame 23 with the scraping plate 17 is pressed and pulled up, so that the scraping plate 17 can be stored in the support frame 20, ensuring unobstructed movement when the electric adjustment base 15 drives the placing plate 16 to move up and down. The grain sample on the placing plate 16 is moved to a position suitable for the discharge module 3 by the electric adjustment base 15. Air is pumped into the box body 1 by the air pump 6, and the excess gas is discharged from the air outlet pipe 11 controlled by the automatic pressure relief valve 43. The voltage and current of the discharge module 3 are adjusted by the high-frequency high-voltage plasma generator 12. The air between the discharge module 3 and the placing plate 16 is ionized into plasma by the current, and the mycotoxin degradation operation is carried out on the grain sample by using the plasma. The real-time voltage and real-time current are observed by the oscilloscope 13, and the data is saved through the waveform diagram. The temperature and humidity inside the box body 1 can be monitored in real time by the temperature and humidity display 14 and the temperature and humidity sensor inside the box body 1.

[0038] The scraping plate 17 is detachably mounted on the mounting frame 23. Before the flattening operation of different grain samples, the scraping plate 17 can be replaced to avoid using the same scraping plate 17 for the flattening of different grain samples, so as to avoid the situation of sample mixing and contamination.

[0039] Please refer to Figures 6-8 In this embodiment: The vibration assembly 34 includes a knocking block 35. A support plate 36 is fixed outside the mounting plate 21. A support 37 is fixed on the top of the support plate 36. A fixing ring 38 is fixed on the top of the support 37. A second slider 39 is slidably arranged on the outside of the fixing ring 38. Compression springs 40 are symmetrically sleeved on the outside of the fixing ring 38. One end of the compression spring 40 is fixed to the support 37, and the other end is fixed to the second slider 39. The two compression springs 40 are located on both sides of the second slider 39. The knocking block 35 is fixed to the outside of the second slider 39. A vibration frame 41 is fixed on the outside of the connecting rod 28, which can knock off the grains attached to the scraping plate 17 and avoid the grains remaining on the scraping plate 17 from being carried into the next sample. The vibration frame 41 is annularly and symmetrically fixed on the outside of the connecting rod 28. The vibration frame 41 and the connecting rod 28 form a Chinese character 'zhong', which can realize the secondary knocking of the connecting rod 28 and the scraping plate 17.

[0040] By setting a fixed ring 38 with a compression spring 40, when the striking block 35 contacts the outside of the vibrating frame 41, the vibrating frame 41 squeezes the striking block 35 as the connecting rod 28 moves, causing the striking block 35 and the second slider 39 to move on the fixed ring 38, squeezing the compression spring 40. When the striking block 35 moves out of the vibrating frame 41, under the action of the compression spring 40, the striking block 35 returns to its initial position and strikes the connecting rod 28. The connecting rod 28 receives the vibration, which is transmitted to the scraper 17 by the mounting bracket 23, causing the scraper to... The grains attached to the plate 17 are knocked off. As the connecting rod 28 continues to move, the striking block 35 is squeezed by the connecting rod 28, which in turn squeezes the compression spring 40. When the striking block 35 leaves the outside of the connecting rod 28, under the action of the compression spring 40, the striking block 35 strikes the vibration frame 41 located below the connecting rod 28. The vibration is transmitted to the scraper 17 through the connecting rod 28 and the mounting frame 23, knocking off the grains attached to the scraper 17 a second time. This can effectively prevent the grain residue on the scraper 17 from being carried into the next sample.
