Description

Technical Field

[0001] This invention relates to the field of grain storage system technology, specifically a grain storage system with a combined ventilation and antibacterial air belt. Background Technology

[0002] Ventilated grate cages are mainly used for grain storage and are generally used in conjunction with grain warehouses. They are mainly suitable for long-term storage of wheat, rice, corn, soybeans, etc. They are the ideal ventilation equipment for large grain warehouses and have the characteristics of convenient storage and long service life.

[0003] Currently, in grain storage systems, a ventilation and antibacterial system is needed to prevent grain from becoming damp and to inhibit bacterial growth. This system ventilates and inhibits bacteria within the grain storage. However, existing technologies use ventilation cages and ozone delivery to the grain storage, respectively. Both methods involve openings in the grain storage walls to deliver airflow and ozone. This results in ozone and airflow concentrating near the openings, requiring a long time to spread before entering the grain storage, leading to low ventilation and antibacterial efficiency. Therefore, we propose a grain storage system with a combined ventilation and antibacterial airflow system. Summary of the Invention

The multiple sets of ventilation pipes are interconnected and connected end to end by snap-fit. One end of each ventilation pipe is connected to the air duct, and a plug is connected to the end of each ventilation pipe. The multiple sets of ventilation pipes are connected at bends by elbows. Several sets of through holes are provided on each ventilation pipe, elbow, and plug. An elastic element is connected to the bottom end of each ventilation pipe, elbow, and plug. The elastic element includes multiple sets of sliding strips, which are slidably installed on the bottom ends of the ventilation pipe, elbow, and plug, respectively. A first spring is fixedly connected to each sliding strip, and multiple sets of first springs are installed inside the ventilation pipe, elbow, and plug and fixedly connected to them. This helps the sliding strips to fit the ground and prevents grain from entering the ventilation pipe and affecting the ventilation effect.

[0006] A grain silo system with a combined ventilation and antibacterial air duct includes a temperature detection module, a humidity detection module, a control module, an ozone detection module, and a ventilation and antibacterial component.

[0010] Preferably, the air inlet includes a corrugated pipe connected to the air outlet pipe. One end of the corrugated pipe is connected to an extension pipe, and one end of the extension pipe is connected to a four-way connector. Three sets of air supply pipes are connected to the four-way connector. Three sets of air ducts are connected to the three sets of air supply pipes, and the three sets of air ducts extend into the ventilation pipe. Several sets of connecting pipes are connected to the air ducts. A bracket is fixedly connected to the outer surface of the connecting pipe. A sealing element is installed inside the connecting pipe, and a pushing element is installed inside the air supply pipe. This facilitates the even distribution of air throughout the bottom of the grain silo, thereby improving drying efficiency.

[0011] Preferably, the sealing element includes a first fixing frame fixedly connected to the connecting pipe, a first sliding column slidably connected to the first fixing frame, a first sealing block fixedly connected to the bottom end of the first sliding column, a connecting plate fixedly connected to multiple sets of the first sealing blocks, and a second spring sleeved on the outside of the first sliding column fixedly connected between the first fixing frame and the first sealing block, which is beneficial for sealing the connecting pipe.

One end of the plug rod is fixedly connected to a second tension spring fixed inside the connecting shaft, and the plug rod is plugged into the rotating shaft. The rotating shaft has a slot adapted to the plug rod, which is beneficial for power transmission.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention incorporates an auxiliary ventilation component. Therefore, during grain storage, when the humidity detection module detects excessive humidity inside the grain silo, the ground cage alone cannot quickly reduce the humidity to a suitable level. The control module then issues a command to start the motor. The motor's rotation drives the coupling, which in turn drives the drive shaft, which in turn drives the first spur gear, which in turn drives the second spur gear, which in turn drives the rotating shaft, which in turn drives the impeller. The rotation of the impeller generates airflow, which then enters the grain storage area through the exhaust duct. The air enters the bellows and then the extension pipe. Through the action of the four-way valve, the air is delivered to the air supply pipe. At this time, the air force pushes the second sealing block to move, and the air supply pipe opens to deliver air into the air belt. During the movement of the second sealing block, the inclined block will move, and the inclined block will squeeze the connecting plate, thus causing the connecting plate to move up. This causes the first sealing block to move up, resulting in the closure of the connecting pipe. Therefore, the air force will stay in the air belt, causing the air belt to inflate and expand, thus filling the dividing belt with gas. After discharge, it is easy to evenly fill the entire grain silo, which is beneficial to the drying and ventilation of the grain. 2. Once the air duct is filled with gas, the control module stops the motor, causing the second sealing block to reset due to the action of the first tension spring. This closes the air duct. Simultaneously, the second sealing block resets the inclined block, causing the first sealing block to reset due to the action of the second spring. This opens the connecting pipe, allowing the gas from the air duct to enter the ventilation pipe and then the grain silo, thus aiding ventilation. The air duct design ensures that the airflow covers the entire bottom of the grain silo, improving grain drying efficiency. This solves the problem in existing technologies where airflow is concentrated near the air duct, resulting in damp grain further away from the duct.

[0016] 3. By incorporating antibacterial components, this invention helps to increase the ozone concentration inside the grain silo. Furthermore, in conjunction with auxiliary ventilation components, it enables ozone to be evenly distributed throughout the entire grain silo, thereby improving the antibacterial efficiency of the grain.

[0020] Please see Figure 1-15 This invention provides a technical solution: a grain silo system with a combined ventilation and antibacterial air duct, comprising a temperature detection module, a humidity detection module, a control module, an ozone detection module, and a ventilation and antibacterial component 9. The temperature detection module, humidity detection module, and ozone detection module are all installed inside the grain silo, respectively used to detect the internal temperature and humidity of the grain silo and the internal ozone concentration. The ventilation and antibacterial component 9 is installed on the outside of the grain silo and communicates with the air duct 1. The ventilation and antibacterial component 9 includes an outer casing 15 installed on the outside of the grain silo and communicating with the air duct 1, and a ventilation slot 16 is formed on the outer casing 15. It also includes an auxiliary ventilation assembly 10 installed inside the outer casing 15. The auxiliary ventilation assembly 10 includes a wind hood 11 installed inside the outer casing 15, and a fan wheel 12 is rotatably connected inside the wind hood 11. The auxiliary ventilation assembly 10 generates wind power through the rotation of the fan wheel 12 to provide auxiliary ventilation for the grain inside the grain silo. When the humidity detection module detects that the humidity inside the grain silo is too high, relying solely on the floor cage ventilation is insufficient to dry the grain silo. Therefore, the auxiliary ventilation equipment is used to improve the ventilation efficiency inside the grain silo, thus preventing the grain from getting damp. The auxiliary ventilation assembly 10 includes an air outlet pipe connected to the wind hood 11. 17 and a rotating shaft 19 fixedly connected to the impeller 12, the rotating shaft 19 being rotatably connected to the hood 11, and the hood 11 also having an air inlet pipe 18 connected to the connecting pipe 48; one end of the air outlet pipe 17 being connected to an air inlet component 31 extending into the ventilation pipe 2, and one end of the rotating shaft 19 being connected to a drive component 20; antibacterial component 13, the antibacterial component 13 including an ozone generator 14 installed inside the outer casing 15 and slidably connected to the outer casing 15, the ozone generator 14 having a connecting pipe 48 connected to the auxiliary ventilation component 10, the antibacterial component 14 being connected to the auxiliary ventilation component 10; the antibacterial component 13 including an ozone generator 14 installed inside the outer casing 15 and slidably connected to the outer casing 15, the ozone generator 14 having a connecting pipe 48 connected to the auxiliary ventilation component 10 ... The antibacterial component 13 generates ozone through the ozone generator 14 and delivers the ozone to the grain silo through the auxiliary ventilation component 10 to inhibit the growth of bacteria in the grain. During long-term storage, some bacteria will grow in the grain, affecting its quality. Therefore, the antibacterial component 13 inhibits the growth of bacteria. The antibacterial component 13 includes a threaded block 49 fixedly connected to the ozone generator 14. A reciprocating screw 50 is threadedly connected to the threaded block 49.

[0022] The air inlet component 31 includes a corrugated pipe 28 connected to the air outlet pipe 17. One end of the corrugated pipe 28 is connected to an extension pipe 29, and one end of the extension pipe 29 is connected to a four-way connector 30. Three sets of air supply pipes 35 are connected to the four-way connector 30. Three sets of air ducts 33 are connected to the three sets of air supply pipes 35 respectively. The three sets of air ducts 33 extend into the ventilation pipe 2 respectively. Several sets of connecting pipes 34 are connected to the air ducts 33. A bracket 32 ​​is fixedly connected to the outer surface of the connecting pipe 34. A sealing element 36 is installed inside the connecting pipe 34, and a pushing element 42 is installed inside the air supply pipe 35.

[0023] The sealing element 36 includes a first fixing frame 37 fixedly connected to the connecting pipe 34, a first sliding column 38 slidably connected to the first fixing frame 37, a first sealing block 39 fixedly connected to the bottom end of the first sliding column 38, a connecting plate 40 fixedly connected to multiple sets of the first sealing blocks 39, and a second spring 41 sleeved on the outside of the first sliding column 38 fixedly connected between the first fixing frame 37 and the first sealing block 39.

[0024] The pushing member 42 includes a second fixed frame 43 fixedly connected to the air duct 35. A second sliding column 44 is slidably connected to the second fixed frame 43. A second sealing block 45 is fixedly connected to one end of the second sliding column 44. A first tension spring 46 sleeved on the outer surface of the second sliding column 44 is fixedly connected between the second sealing block 45 and the second fixed frame 43. An inclined block 47 that contacts and cooperates with the connecting plate 40 is fixedly connected to one end of the second sealing block 45.

[0025] The transmission component 52 includes a fixed seat 53 sleeved on the outer surface of the connecting shaft 51. A coil 54 sleeved on the outer surface of the connecting shaft 51 is fixedly connected to the fixed seat 53. An electromagnet 55 sleeved on the outer surface of the connecting shaft 51 is connected to the coil 54. A magnet 56 with opposite magnetic properties is installed on one side of the electromagnet 55. A plug rod 57 slidably connected to the rotating shaft 19 is fixedly connected to the magnet 56. A second tension spring 59 fixed inside the connecting shaft 51 is fixedly connected to one end of the plug rod 57. The plug rod 57 is plugged into the rotating shaft 19. A slot 58 adapted to the plug rod 57 is provided on the rotating shaft 19.

[0026] A ventilated floor cage includes an air duct 1, multiple sets of ventilation pipes 2, and elbows 3. The multiple sets of ventilation pipes 2 are interconnected and connected end to end by snap-fit. One end of each ventilation pipe 2 is connected to the air duct 1, and a plug 4 is connected to the end of each ventilation pipe 2. The multiple sets of ventilation pipes 2 are connected to each other at bends by elbows 3. Several sets of through holes 5 are provided on each ventilation pipe 2, elbow 3, and plug 4, and elastic elements 6 are connected to the bottom ends of each ventilation pipe 2, elbow 3, and plug 4. The elastic element 6 includes multiple sets of sliding strips 7, which are slidably installed on the bottom ends of the ventilation pipe 2, the elbow 3, and the plug 4, respectively. A first spring 8 is fixedly connected to each sliding strip 7, and multiple sets of first springs 8 are installed inside the ventilation pipe 2, the elbow 3, and the plug 4 and fixedly connected thereto.

[0027] During grain storage, when the humidity detection module detects excessive humidity inside the grain silo, the ground cage alone cannot quickly reduce the humidity to a suitable level. Therefore, the control module will issue a command to start motor 21. The rotation of motor 21 will drive coupling 22, which in turn drives drive shaft 23, which in turn drives first spur gear 25, then second spur gear 26, which in turn drives rotating shaft 19, and finally the impeller 12. This rotation of the impeller 12 will generate wind, which will then enter the corrugated pipe 28 through the outlet pipe 17 (the corrugated pipe 28 allows for varying lengths to be adjusted for different thicknesses of grain silo walls, facilitating connection with the outlet pipe 17), and then into extension pipe 29. Finally, through the four-way connector 30, the wind will be delivered to the air supply pipe 35. The wind will then push the second sealing block 45 to move, opening the air supply pipe 35 and delivering wind into the air duct 33. During the process, the inclined block 47 will move, which will then press the connecting plate 40, causing the connecting plate 40 to move upward, and thus the first sealing block 39 to move upward, resulting in the closure of the connecting pipe 34. As a result, the air force will remain in the air belt 33, causing the air belt 33 to inflate. When the air belt 33 is full of gas, the control module controls the motor 21 to stop running. As a result, the second sealing block 45 is reset due to the action of the first tension spring 46, thus closing the air supply pipe 35. At this time, the second sealing block 45 drives the inclined block 47 to reset, and the first sealing block 39 is reset due to the action of the second spring 41. Therefore, the connecting pipe 34 is opened, and the gas in the air belt 33 will enter the ventilation pipe 2 through the connecting pipe 34, thus entering the grain silo, thereby assisting the ventilation of the grain silo. Due to the setting of the air belt 33, the air force can cover the entire bottom of the grain silo, thereby improving the drying efficiency of the grain. Therefore, it solves the problem in the prior art where the air force is concentrated near the air duct 1, resulting in the grain far from the air duct 1 being relatively damp.

[0028] During grain storage, antibacterial treatment is required to ensure grain quality. During this process, an ozone detection module monitors the ozone concentration inside the grain silo. If the concentration is too low, ozone needs to be introduced into the silo. At this time, the control module activates the ozone generator 14, energizing coil 54 and simultaneously running motor 21. The energization of coil 54 causes electromagnet 55 to become magnetic, opposite to the magnet 56, thus moving magnet 56. This, in turn, moves the insertion rod 57, placing it into slot 58 of rotating shaft 19. When rotating shaft 19 rotates, it rotates the insertion rod 57, which in turn rotates the connecting shaft 51, thus driving the reciprocating screw 5. The rotation of the screw 49 causes the threaded block 49 to move, which in turn moves the ozone generator 14. When the threaded block 49 moves to the end of the reciprocating screw 50, the connecting pipe 48 moves and connects with the air inlet pipe. At this time, the coil 54 is de-energized, so the reciprocating screw 50 stops rotating. At this time, the rotation of the impeller 12 delivers ozone into the air belt 33. When the air belt 33 is full of ozone, the motor 21 stops running. Therefore, the ozone enters the grain silo evenly, which helps to improve the antibacterial efficiency. After the concentration in the grain silo is detected by the ozone detection module and meets the standard, the coil 54 is energized again. At this time, due to the action of the reciprocating screw 50, the threaded block 49 moves the ozone generator 14 away from the air inlet pipe, causing the connecting pipe 48 to disconnect from the air inlet pipe.
