Therefore, they should not be construed as limitations on this invention.

[0032] like Figures 1-6 As shown in the figure, an embodiment of the present invention provides a sterile rice storage bin, including a support 1, a bin body 2 disposed at the upper end of the support 1, a butterfly valve disposed at the lower end of the bin body 2, and further including:

[0033] A ventilation component 3 is fixedly installed on the chamber 2. The ventilation component 3 includes an air inlet pipe 30, which passes through a multi-stage filtration mechanism 31 and enters the chamber 2. The multi-stage filtration mechanism 31 is fixedly installed on the outside of the chamber. The multi-stage filtration mechanism 31 can sterilize the airflow used for ventilation through the ultraviolet lamp tube 310 installed inside it. A three-dimensional ventilation mechanism 32 is fixedly installed inside the chamber 2. The three-dimensional ventilation mechanism 32 can make the airflow entering the chamber 2 evenly distributed. Multiple temperature sensors 33 are installed inside the chamber 2.

[0034] The impurity removal component 4 is disposed on the lower side of the chamber body 2. The impurity removal component 4 includes a drive motor 40, which is fixedly disposed on the chamber body 2. The output end of the drive motor 40 is provided with a drive bevel gear 41. A rotating ring 42 is disposed on the lower side of the chamber body 2 by means of rotation. A plurality of cleaning brushes 43 are evenly disposed below the rotating ring 42 along its axial direction. An annular rack 44 is disposed on the lower side of the rotating ring 42. The drive bevel gear 41 meshes with the annular rack 44.

[0035] In another embodiment of the present invention, the silo body 2 includes a cylindrical section 20, which is disposed on the support 1. A silo cover 21 is disposed at the upper end of the cylindrical section 20. The silo cover 21 is provided with a feeding port and an exhaust valve. A conical section 22 is disposed at the lower end of the cylindrical section 20. The cylindrical section 20, the silo cover 21, and the conical section 22 are all composed of an inner layer and an outer layer. An insulation interlayer is disposed between the inner and outer layers of the cylindrical section 20 and the silo cover 21. An installation space is formed between the inner and outer layers of the conical section 22. The impurity removal component 4 is disposed in the installation space. A filter hole is provided on the inner layer of the conical section 22. A collection frame 23 is disposed on one side of the lower end of the conical section 22. The conical section 22 is connected to the collection frame 23 through an impurity discharge hole.

[0036] The specific implementation method is as follows: After the rice is hulled, it is fed into the storage chamber 2 through the feeding port on the cover 21 for storage. After the rice enters the storage chamber 2, the feeding port is sealed, and the storage chamber 2 directly contacts the rice through its inner layer. The rice is kept warm by an insulation layer. At this time, the temperature sensor 33 measures the temperature of the rice stored in the storage chamber 2 to obtain the real-time status of the rice during storage. Simultaneously, the three-dimensional ventilation mechanism 32 ventilates the storage chamber 2 to reduce the heat generated inside the rice during storage, thereby preventing mold growth. When the three-dimensional ventilation mechanism 32 ventilates the storage chamber 2, the air entering the storage chamber 2 is first filtered and sterilized by a multi-stage filtration mechanism 31 and an ultraviolet lamp 310 to prevent mold and other impurities from entering the storage chamber 2 and causing the rice to mold. When the three-dimensional ventilation mechanism 32 ventilates into the silo 2, impurities mixed in during the rice hulling process can fall into the conical section 22. The filter holes on the inner layer of the conical section 22 can filter the impurities. At this time, the impurity removal component 4 cleans and collects the impurities. Specifically, the drive motor 40 drives the drive bevel gear 41 to rotate, which in turn drives the ring rack 44 to rotate. This causes the ring rack 44 to drive the rotating ring 42 to rotate on the silo 2, which in turn drives multiple cleaning brushes 43 to rotate within the installation space of the conical section 22. After rotation, the cleaning brushes 43 clean and collect the impurities filtered through the filter holes on the conical section 22. When the cleaning brushes 43 rotate to clean the impurities, they can carry the impurities filtered through the filter holes to the discharge hole, so that the impurities filtered through the filter holes can pass through the discharge hole and fall into the collection frame 23 for collection.

[0037] In another embodiment of the present invention, the multi-stage filtration mechanism 31 includes a housing 311. A cyclone separator 312, a condenser dehumidifier 313, and a plurality of filters 314 are sequentially arranged at the bottom of the housing 311. A sterilization box 315 is also arranged at the bottom of the housing 311. A plurality of ultraviolet lamps 310 are arranged inside the sterilization box 315. The air inlet pipe 30 passes sequentially through the cyclone separator 312, the condenser dehumidifier 313, the plurality of filters 314, and the sterilization box 315 and is connected to the three-dimensional ventilation mechanism 32.

[0038] The specific implementation method is as follows: When the three-dimensional ventilation mechanism 32 ventilates the chamber 2, the outside air is pumped into the multi-stage filtration mechanism 31 through the air inlet pipe 30 for disinfection and filtration. Specifically, after the outside air is pumped into the outer shell 311 through the air inlet pipe 30, it first enters the cyclone separator 312, which removes dust and other small particulate impurities from the air. After the impurities are removed, the air overflows from the cyclone separator 312 and enters the condenser dehumidifier 313 for condensation and dehumidification, thereby removing moisture from the air. At the same time, after the moisture is removed, it passes through multiple filters 314 to remove the tiny particles. Finally, the airflow enters the disinfection chamber. The sterilization box 315 uses multiple ultraviolet lamps 310 to irradiate and sterilize the dehumidified and impurity-removed air. The sterilized air then enters the three-dimensional ventilation mechanism 32, which evenly sprays the air into the rice in the storage chamber 2. This cools the rice and allows it to move within the chamber, facilitating the removal of impurities from the rice and causing them to fall into the conical section 22. Finally, the air is exhausted through the exhaust valve on the storage cover 21, maintaining normal pressure in the storage chamber 2 and preventing damage due to excessive pressure.

[0039] In another embodiment of the present invention, the sterilization box 315 includes a box body 3150, a serpentine tube 3151 is provided inside the box body 3150, the serpentine tube 3151 is made of transparent material, a plurality of ultraviolet lamp tubes 310 are provided above the serpentine tube 3151, and a reflector 3152 is attached to the inner wall of the box body 3150.

[0040] The specific implementation method is as follows: When the filtered and impurity-removed air enters the sterilization box 315 for sterilization, the gas enters the box body 3150 through the serpentine tube 3151. The serpentine tube 3151 is made of transparent material so that multiple ultraviolet lamps 310 provided on the upper inner side of the box body 3150 emit ultraviolet rays to irradiate and sterilize the air inside the serpentine tube 3151. The serpentine tube 3151 can prolong the residence time of the air in the box body 3150 so that the air can be fully irradiated by the ultraviolet rays emitted by the ultraviolet lamps 310. At the same time, the reflector 3152 attached to the inner wall of the box body 3150 can reflect ultraviolet rays so that the ultraviolet rays emitted by the ultraviolet lamps 310 can fully irradiate and sterilize the air inside the serpentine tube 3151.

[0041] In another embodiment of the present invention, the three-dimensional ventilation mechanism 32 includes a spiral air outlet pipe 320, which is disposed inside the chamber 2. A plurality of branch pipes 321 are evenly disposed on the spiral air outlet pipe 320. Both the branch pipes 321 and the spiral air outlet pipe 320 are provided with air outlet holes, and the air outlet holes are provided with filters.

[0042] The specific implementation method is as follows: After dehumidification, impurity removal and sterilization, the air enters the three-dimensional ventilation mechanism 32, so that the three-dimensional ventilation mechanism 32 sprays the treated air evenly onto the rice in the storage chamber 2. Specifically, the treated air is transported along the axial direction of the storage chamber 2 through the spiral air outlet pipe 320, and at the same time, the treated air is transported along the radial direction of the storage chamber 2 through the branch pipe 321, so that the spiral air outlet pipe 320 and the branch pipe 321 spray the treated air evenly onto the rice through the air outlet, so that the air cools down the heat generated during the storage of the rice. At the same time, the filter screen provided at the air outlet can prevent the rice from entering the spiral air outlet pipe 320 or the branch pipe 321 through the air inlet pipe 30.

[0043] In another embodiment of the present invention, the impurity removal component 4 further includes an impurity collection groove 45, which is disposed on the inner side of the outer layer of the conical section 22 and is spiral in shape.

[0044] The specific implementation method is as follows: The impurity collection tank 45 is arranged in a spiral shape on the inner side of the outer layer of the conical section 22. When the spiral air outlet pipe 320 and the branch pipe 321 spray the treated air evenly onto the rice through the air outlet, the air sprayed onto the rice can drive the rice to move and increase the gap between the rice grains, so that the impurities between the rice grains fall into the conical section 22. The impurities are filtered through the filter holes of the inner layer of the conical section 22 and fall into the installation space. The impurities falling from the filter holes into the installation space will fall into the impurity collection tank 45. At this time, the drive motor 40 drives the drive bevel gear 41 to rotate, so that the drive bevel gear 41 drives the rotating ring 42 through the ring rack 44 in the bin. The rotating ring 42 drives multiple cleaning brushes 43 to rotate within the installation space of the conical section 22. After rotation, the cleaning brushes 43 clean and collect the impurities filtered through the filter holes on the conical section 22. When the cleaning brushes 43 rotate to clean the impurities, they can carry the impurities filtered through the filter holes to the discharge hole, so that the impurities filtered through the filter holes can pass through the discharge hole and fall into the collection frame 23 for collection. In addition, when the cleaning brushes 43 rotate with the rotating ring 42, they can drive the impurities in the impurity collection groove 45 to move. Since the impurity collection groove 45 is spiral-shaped, it is convenient for the impurities to move along the impurity collection groove 45 and fall into the collection frame 23 through the discharge hole.

[0045] In another embodiment of the present invention, a switching component 5 is further included. The switching component 5 includes two support frames 50, which are respectively located on the upper side of the cylindrical section 20 and the middle of the conical section 22 of the inner layer. A hollow shaft 51 is provided between the two support frames 50. A feeding frame 510 is provided at the lower end of the hollow shaft 51. The lower end of the hollow shaft 51 is connected to the air inlet pipe 30. A solenoid valve is provided on the air inlet pipe 30. A dynamic seal is formed between the hollow shaft 51 and the air inlet pipe 30. A discharge unit 52 is rotatably provided at the upper end of the hollow shaft 51. A position sensor 53 is provided on the lower side of the end of the discharge unit 52 away from the hollow shaft 51.

[0046] The specific implementation method is as follows: When storing rice in the storage chamber 2, the position sensor 53 detects the height of the rice in the storage chamber 2. When the height of the rice in the storage chamber 2 is close to that of the position sensor 53, the addition of rice to the storage chamber 2 is stopped. The rice generates heat during storage. At this time, treated air is transported axially along the storage chamber 2 through the spiral air outlet pipe 320, and simultaneously radially along the storage chamber 2 through the branch pipe 321. This allows the spiral air outlet pipe 320 and the branch pipe 321 to evenly spray the treated air onto the rice through the air outlet holes, thus facilitating the air exchange between the rice and the heat generated during storage. The generated heat is used to cool down the rice, and at the same time, the solenoid valve is opened, allowing air to enter the bottom of the hollow shaft 51 through the air inlet pipe 30. At this time, the air flows rapidly from bottom to top inside the hollow shaft 51 and generates negative pressure. Under the action of negative pressure, the rice can enter the hollow shaft 51 through the feed frame 510, so that the air can transfer the rice inside the hollow shaft 51 from the bottom to the top of the hollow shaft 51. The rice that moves to the top of the hollow shaft 51 with the air can be sprayed out from the discharge unit 52. When the rice is sprayed out, the discharge unit 52 can rotate at the top of the hollow shaft 51 so that the rice is sprayed out more evenly.

[0047] In another embodiment of the present invention, the transposition component 5 further includes a mounting frame 54, which is fixedly disposed in the middle of the inner side of the hollow shaft 51. A pressure motor 55 is disposed inside the mounting frame 54, and a rotating shaft 56 is disposed at the output end of the pressure motor 55. A fan blade 57 is fixedly disposed on the rotating shaft 56. A protective cover 58 is disposed at the upper end of the mounting frame 54, and the fan blade 57 is disposed inside the protective cover 58.

[0048] The specific implementation method is as follows: When the air intake pipe 30 uses the negative pressure generated by the air to move the rice at the bottom of the bin 2 to the top of the bin 2, the negative pressure generated by the air may not be able to move the rice. At this time, the pressurizing motor 55 drives the rotating shaft 56 to rotate, which in turn drives the fan blades 57 mounted on it to rotate. This causes the fan blades 57 to generate airflow and negative pressure when they rotate, ensuring that the hollow shaft 51 can continue to move the rice at the bottom of the bin 2 to the top of the bin 2. The fan blades 57 are wrapped by the protective cover 58 to prevent the rice from breaking when the fan blades 57 rotate.

[0049] In another embodiment of the present invention, the discharge unit 52 includes a rotating block 520, which is rotatably disposed at the upper end of the hollow shaft 51. The upper end of the rotating shaft 56 passes through the protective cover 58 and is connected to the rotating block 520. The rotating block 520 is uniformly provided with a plurality of arc-shaped discharge pipes 521 along its circumference. The position sensor 53 is disposed at the end of the arc-shaped discharge pipe 521 away from the rotating block 520.

[0050] The specific implementation method is as follows: The pressurizing motor 55 drives the fan blade 57 to rotate through the rotating shaft 56. When the fan blade 57 rotates and generates airflow and negative pressure to transfer the rice at the bottom of the silo 2 to the top of the silo 2, the pressurizing motor 55 drives the rotating block 520 to rotate synchronously through the rotating shaft 56. This causes the rotating block 520 to drive the arc-shaped discharge pipe 521, which is evenly arranged on its outer side, to rotate synchronously. This allows the rice transported to the upper end of the hollow shaft 51 to be sprayed out from the arc-shaped discharge pipe 521 with the air. The rotating arc-shaped discharge pipe 521 evenly sprays the rice transported from the bottom of the silo 2 to the rotating block 520 from the hollow shaft 51 onto the top of the silo 2, so as to transfer the rice. The rice at the bottom of the silo 2 is transferred to the top of the silo 2, and the rice in the middle of the silo 2 is transferred to the edge of the silo 2, so that the air sprayed by the spiral air outlet pipe 320 and the branch pipe 321 can cool down the heat generated during rice storage more quickly.

[0051] Working principle: After the rice is hulled, it is fed into the storage chamber 2 through the feeding port on the cover 21. The position sensor 53 detects the height of the rice in the storage chamber 2. When the height of the rice in the storage chamber 2 is close to the position sensor 53, the feeding of rice in the storage chamber 2 is stopped. After the rice is stored in the storage chamber 2, the feeding port is sealed. The storage chamber 2 is in direct contact with the rice through its inner layer and is kept warm by the insulation layer. At this time, the temperature sensor 33 measures the temperature of the rice stored in the storage chamber 2 to obtain the real-time status of the rice storage. At the same time, the three-dimensional ventilation mechanism 32 ventilates the storage chamber 2 to reduce the heat generated inside the rice during storage and prevent the rice from becoming moldy. When the three-dimensional ventilation mechanism 32 ventilates the storage chamber 2, the air entering the storage chamber 2 is first filtered and sterilized by the multi-stage filtration mechanism 31 and the ultraviolet lamp 310 to prevent mold and other impurities from entering the storage chamber 2 and causing the rice to become moldy.

[0052] When the three-dimensional ventilation system 32 ventilates the chamber 2, the outside air is pumped into the multi-stage filtration system 31 through the air inlet pipe 30 for disinfection and filtration. Specifically, after the outside air is pumped into the outer shell 311 through the air inlet pipe 30, it first enters the cyclone separator 312, which removes dust and other small particulate impurities from the air. The air after removing impurities overflows from the cyclone separator 312 and enters the condenser dehumidifier 313 for condensation and dehumidification, thereby removing moisture from the air. At the same time, the air after removing moisture passes through multiple filters 314 to remove tiny particles. Finally, the airflow enters the sterilization box 315, which then... 15. Multiple ultraviolet lamps 310 inside the sterilization box 315 irradiate and sterilize the dehumidified and impurity-removed air. Specifically, when the filtered and impurity-removed air enters the sterilization box 315 for sterilization, the gas enters the box body 3150 through a serpentine tube 3151. The serpentine tube 3151 is made of transparent material so that the multiple ultraviolet lamps 310 located on the upper inner side of the box body 3150 emit ultraviolet rays to irradiate and sterilize the air inside the serpentine tube 3151. The serpentine tube 3151 can prolong the residence time of the air in the box body 3150 so that the air is fully irradiated by the ultraviolet rays emitted by the ultraviolet lamps 310. At the same time, a reflector 3 is attached to the inner wall of the box body 3150. 152 can reflect ultraviolet rays, so that the ultraviolet rays emitted by the ultraviolet lamp tube 310 can fully irradiate and sterilize the air inside the serpentine tube 3151; finally, the sterilized air enters the three-dimensional ventilation mechanism 32, and the three-dimensional ventilation mechanism 32 evenly sprays the air into the bin 2 onto the rice, so that the air entering the bin 2 can cool the rice, and at the same time, the gas can make the rice move in the bin, so that impurities among the rice can fall into the conical section 22. The air entering the bin 2 is finally discharged through the exhaust valve on the bin cover 21, so that the bin 2 can maintain normal pressure and avoid damage to the bin 2 due to excessive pressure; after sterilization After being humidified, cleaned, and sterilized, the air enters the three-dimensional ventilation mechanism 32, which evenly sprays the treated air onto the rice inside the storage chamber 2. Specifically, the treated air is transported along the axial direction of the storage chamber 2 through the spiral air outlet pipe 320, and simultaneously transported along the radial direction of the storage chamber 2 through the branch pipe 321. This allows the spiral air outlet pipe 320 and the branch pipe 321 to evenly spray the treated air onto the rice through the air outlet, thereby cooling the heat generated during rice storage. At the same time, the filter screen at the air outlet prevents rice from entering the spiral air outlet pipe 320 or the branch pipe 321 through the air inlet pipe 30.

[0053] Furthermore, when the three-dimensional ventilation mechanism 32 ventilates into the silo 2, impurities mixed in during the rice hulling process can fall into the conical section 22. The filter holes on the inner layer of the conical section 22 can filter the impurities. At this time, the impurity removal component 4 cleans and collects the impurities. Specifically, the drive motor 40 drives the drive bevel gear 41 to rotate, which in turn drives the ring rack 44 to rotate. This causes the ring rack 44 to drive the rotating ring 42 to rotate on the silo 2, which in turn drives multiple cleaning brushes 43 to rotate on the conical section 2. The cone section 22 rotates within its installation space, allowing the cleaning brush 43 to clean and collect impurities filtered through the filter holes on the cone section 22. As the cleaning brush 43 rotates to clean impurities, it carries these impurities to the discharge hole, allowing them to fall into the collection frame 23 for collection. The impurity collection trough 45 is spirally arranged on the inner side of the outer layer of the cone section 22. When the spiral air outlet pipe 320 and branch pipe 321 evenly spray treated air onto the rice through the air outlet, the air is sprayed towards the rice... The air in the rice can move the rice grains and increase the gaps between them, causing impurities to fall into the conical section 22. These impurities are filtered through the inner filter holes of the conical section 22 and fall into the installation space. The impurities falling from the filter holes into the installation space will fall into the impurity collection tank 45. At this time, the drive motor 40 drives the drive bevel gear 41 to rotate, which in turn drives the rotating ring 42 to rotate on the bin body 2 via the ring rack 44. This rotating ring 42 then drives multiple cleaning brushes 43 to rotate within the installation space of the conical section 22. The cleaning brush 43, after rotating, cleans and collects the impurities filtered through the filter holes on the conical section 22. When the cleaning brush 43 rotates to clean the impurities, it can carry the impurities filtered through the filter holes to the discharge hole, so that the impurities filtered through the filter holes can pass through the discharge hole and fall into the collection frame 23 for collection. In addition, when the cleaning brush 43 rotates with the rotating ring 42, it can drive the impurities in the impurity collection groove 45 to move. Since the impurity collection groove 45 is spiral-shaped, it is convenient for the impurities to move along the impurity collection groove 45 and fall into the collection frame 23 through the discharge hole.

[0054] When rice is added and stored, it generates heat. At this time, treated air is transported axially along the compartment 2 via the spiral air outlet pipe 320, and radially along the compartment 2 via the branch pipe 321. This allows the spiral air outlet pipe 320 and the branch pipe 321 to evenly spray the treated air onto the rice through the air outlet holes, thus cooling the rice and reducing the heat generated during storage. Simultaneously, the solenoid valve opens, allowing air to enter the bottom of the hollow shaft 51 through the air inlet pipe 30. The air then flows rapidly upwards within the hollow shaft 51, creating negative pressure. Under the influence of this negative pressure... Rice can enter the hollow shaft 51 through the feed frame 510, so that air can transfer the rice into the hollow shaft 51 from the bottom to the top of the hollow shaft 51. The rice that moves to the top of the hollow shaft 51 with the air can be sprayed out from the discharge unit 52. When the rice is sprayed out, the discharge unit 52 can rotate at the top of the hollow shaft 51 so that the rice can be sprayed out more evenly. When the air inlet pipe 30 uses the negative pressure generated by the air to move the rice from the bottom of the bin 2 to the top of the bin 2, there may be a situation where the negative pressure generated by the air is not enough to move the rice. At this time, the pressure motor 55 drives the rotating shaft 56. The rotation of the rotating shaft 56 causes the fan blades 57 mounted on it to rotate, thereby generating airflow and negative pressure when the fan blades 57 rotate. This ensures that the hollow shaft 51 can continue to transfer the rice from the bottom of the bin 2 to the top of the bin 2. The fan blades 57 are also protected by a protective cover 58 to prevent the rice from breaking during rotation. The pressurizing motor 55, via the rotating shaft 56, drives the fan blades 57 to rotate. As the fan blades 57 generate airflow and negative pressure to continue transferring the rice from the bottom of the bin 2 to the top of the bin 2, the pressurizing motor 55, via the rotating shaft 56, drives the rotating block 520 to rotate synchronously. The rotating block 520 drives the arc-shaped discharge pipe 521, which is evenly arranged on its outer side, to rotate synchronously. This allows the rice conveyed to the upper end of the hollow shaft 51 to be sprayed out of the arc-shaped discharge pipe 521 along with the air. During rotation, the arc-shaped discharge pipe 521 evenly sprays the rice conveyed from the bottom of the silo 2 to the rotating block 520 onto the top of the silo 2, so as to transfer the rice. The rice at the bottom of the silo 2 is transferred to the top of the silo 2, and the rice in the middle of the silo 2 is transferred to the edge of the silo 2, so that the spiral air outlet pipe 320 and the branch pipe 321 can spray air more quickly to cool down the heat generated during rice storage.
