Description

Technical Field

[0001] This application relates to the field of grain storage, and in particular to a low-energy circulating ventilation system. Background Technology

[0002] A grain warehouse is a specialized building used to store grain. It is used to store large quantities of grain and protect it from adverse environmental factors such as dampness, insects, rodents, and mold, thereby ensuring the quality and quantity of the grain.

[0003] In existing technology, grain silos are usually equipped with fans that supply air to the silo. The air flows towards the roof of the silo and is exhausted through the vents. The air does not easily come into full contact with the grain inside the silo, resulting in uneven ventilation. This makes the grain at the bottom of the silo prone to dampness and mold. Summary of the Invention

[0004] To improve the problem of uneven ventilation in grain warehouses, this application provides a low-energy-consumption circulating ventilation system.

[0005] This application provides a low-energy-consumption circulating ventilation system, which adopts the following technical solution:

[0006] A low-energy-consumption circulating ventilation system includes an air pump connected to a grain silo, a sealing device, multiple air inlet pipes spaced apart and connected to the inner wall of the grain silo, and multiple air outlet pipes spaced apart and connected to the inner wall of the grain silo. The air inlet pipes and air outlet pipes are located on opposite inner walls of the grain silo. The air pump's suction end is connected to the inner cavity of the multiple air outlet pipes. The air pump can drive air in the air inlet pipes through the inner cavity of the grain silo and out of the air outlet pipes. The sealing device includes a sealing membrane, a sealing plate, and a sealing tube. The sealing plate is connected to the circumferential inner wall of the grain silo and is located above the air inlet pipes and air outlet pipes. The sealing plate has a sealing cavity for the sealing tube to be embedded in. When the circumferential edge of the sealing membrane is embedded in the sealing cavity, it drives the sealing tube to be embedded in the sealing cavity. The inner wall of the sealing cavity and the outer wall of the sealing tube clamp the two sides of the sealing membrane to form a limiting position.

[0007] By adopting the above technical solution, the sealing plate is located above the air inlet and outlet pipes. The circumferential edge of the sealing film is embedded in the sealing cavity, driving the sealing tube to be embedded in the sealing cavity. The inner wall of the sealing cavity and the outer wall of the sealing tube clamp the two sides of the sealing film to form a limit, thereby limiting the circumferential edge of the sealing film on the sealing plate. The sealing film covers the top surface of the grain in the grain silo to form a seal. When the air pump drives the air in the air inlet pipe through the inner cavity of the grain silo and out from the air outlet pipe, the sealing film restricts the air from flowing towards the top of the grain silo, driving the air to fully contact the grain under the sealing film, thereby improving the ventilation efficiency in the grain silo and ensuring that the grain at the bottom of the grain silo is not easily damp and moldy. Users do not need to increase the suction power of the air pump to improve the ventilation efficiency in the grain silo, reducing energy consumption and thus reflecting the concept of energy saving.

[0008] Optionally, the sealing tube includes a positioning tube and a reinforcing ring, the reinforcing ring being connected to the outer periphery of the positioning tube, and the outer ring of the reinforcing ring being able to press against the surface of the sealing film.

[0009] By adopting the above technical solution, the reinforcing ring is connected to the outer periphery of the positioning tube, and the outer ring of the reinforcing ring and the inner wall of the sealing cavity clamp the two sides of the sealing membrane to form a limit, making it difficult for the edge of the sealing membrane to detach from the sealing cavity, thereby improving the sealing stability of the sealing membrane for grain in the grain warehouse.

[0010] Optionally, the sealing device further includes a reinforcing component, which includes an air supply pipe and multiple elastic blocks. The sealing plate has an air supply channel on its surface. One end of the air supply pipe is rotatably connected to the inner wall of the air supply channel, and the other end of the air supply pipe faces the sealing cavity. The surface of the reinforcing ring has an air supply hole for the end of the air supply pipe to be embedded in. Multiple elastic blocks are spaced apart and connected to the inner wall of the air supply hole. The multiple elastic blocks are spliced ​​to form a circular plate and close the air supply hole. When the end of the air supply pipe squeezes the elastic block to deform and embed into the sealing cavity, the air in the air supply channel enters the inner cavity of the reinforcing ring through the inner cavity of the air supply pipe.

[0011] By adopting the above technical solution, before the sealing tube is installed, the air supply tube is driven to rotate away from the sealing cavity, so that the air supply tube is less likely to interfere with the sealing tube being embedded in the sealing cavity. When the sealing tube is embedded in the sealing cavity, the outer wall of the reinforcing ring and the inner wall of the sealing cavity clamp the two sides of the sealing membrane to form a limit. At the same time, the air supply tube is driven to rotate closer to the sealing cavity, and the end of the air supply tube squeezes the elastic block to deform. The sealing effect of the elastic block on the air supply hole disappears, and the air in the air supply channel can enter the inner cavity of the reinforcing ring through the inner cavity of the air supply tube. The reinforcing ring expands under pressure and presses against the surface of the sealing membrane, further improving the clamping force between the reinforcing ring and the sealing membrane.

[0012] Optionally, the reinforcement component further includes a reset elastic element, one end of which is connected to the inner wall of the air supply channel in the direction of elastic force, and the other end of which is connected to the rotating shaft of the air supply pipe. The reset elastic element has the tendency to drive the air supply pipe to rotate toward the direction of the sealing cavity.

[0013] By adopting the above technical solution, when the sealing tube is embedded in the sealing cavity, the air supply tube is released, and the elastic force of the reset elastic element drives the air supply tube to rotate towards the sealing cavity. The end of the air supply tube squeezes the elastic block to deform, and the sealing effect of the elastic block on the air supply hole disappears. The inner cavity of the air supply tube connects the inner cavity of the reinforcing ring bladder and the air supply channel, realizing the automatic connection between the air supply tube and the reinforcing ring bladder. Users do not need to drive the air supply tube close to the sealing cavity, thereby improving the ease of use of the low-energy circulating ventilation system.

[0014] Optionally, the reinforcement assembly further includes a reinforcement gear, a reinforcement plate, a positioning plate, and a reinforcement piston. The sealing plate has a rotating cavity for the reinforcement gear to rotate, and the rotating cavity is connected to the air supply channel. The reinforcement plate is connected to the surface of the reinforcement gear, and the positioning plate is slidably connected to the surface of the reinforcement plate. A limiting space is left between the positioning plate and the reinforcement plate for the end of the sealing membrane to be embedded. The reinforcement piston is slidably connected to the inner wall of the air supply channel, and the surface of the reinforcement piston has a toothed groove that meshes with the reinforcement gear.

[0015] By adopting the above technical solution, the end of the sealing membrane is embedded in the limiting space. The positioning plate and the reinforcing plate clamp the two sides of the sealing membrane to form a limiting position. When the air pressure in the grain silo is too high, it drives the sealing membrane to deform towards the direction of the grain silo roof. The reinforcing plate is connected to the surface of the reinforcing gear. The end of the sealing membrane drives the reinforcing plate to approach the sealing cavity, which drives the reinforcing gear to rotate. The reinforcing piston has a tooth groove that meshes with the reinforcing gear. It drives the reinforcing piston to slide on the inner wall of the air supply channel. The air pressure in the air supply channel increases. The air in the air supply channel enters the inner cavity of the reinforcing ring bladder through the air supply pipe. The outer ring of the reinforcing ring bladder is pressurized and expands and presses against the surface of the sealing membrane, increasing the pressing force of the outer ring of the reinforcing ring bladder against the sealing membrane. This makes the edge of the sealing membrane less likely to be separated from the sealing cavity by the air pressure in the grain silo, thereby improving the limiting stability of the edge of the sealing membrane in the sealing cavity.

[0016] Optionally, the reinforcement component further includes an elastic ring, the inner ring of which is connected to the outer periphery of the air supply pipe, the outer ring of which is connected to the slot of the air supply channel, and the elastic ring seals the inner cavity of the air supply channel.

[0017] By adopting the above technical solution, the inner ring of the elastic ring is connected to the outer circumference of the air supply pipe, and the outer ring of the elastic ring is connected to the slot of the air supply channel. The elastic ring seals the inner cavity of the air supply channel, allowing the air in the air supply channel to enter the inner cavity of the air supply pipe stably. At the same time, the elastic ring has a certain degree of elasticity, so that when the air supply pipe rotates on the inner wall of the air supply channel, the elastic ring is compressed and deformed, making the elastic ring less likely to crack due to the pressure of the air supply pipe, thereby improving the stability of the elastic ring's sealing of the inner cavity of the air supply channel.

[0018] Optionally, the reinforcement component further includes a limiting elastic element, one end of which is connected to the surface of the reinforcement plate in the direction of elastic force, and the other end of which is connected to the surface of the positioning plate in the direction of elastic force. The limiting elastic element has the tendency to elastically drive the positioning plate to slide closer to the reinforcement plate.

[0019] By adopting the above technical solution, when the end of the sealing film is embedded in the limiting space, the elastic force of the limiting elastic element drives the positioning plate to slide towards the fixed plate. The surface of the positioning plate and the surface of the fixed plate clamp the two sides of the sealing film to form a fixed position, making it difficult for the end of the sealing film to detach from the limiting space, thereby improving the limiting stability of the sealing film in the limiting space.

[0020] Optionally, the reinforcing plate is connected to a clamping assembly, which includes a clamping water bladder, a quicklime block, a thermal expansion and contraction block, and multiple elastic arc blocks. The clamping water bladder is connected to the surface of the reinforcing plate away from the limiting elastic element. One end of the quicklime block is connected to the surface of the clamping water bladder, and the other end of the quicklime block is connected to the surface of the thermal expansion and contraction block. The clamping water bladder has a water outlet hole on its surface facing the quicklime block. Multiple elastic arc blocks are spaced apart and connected to the inner wall of the water outlet hole. Multiple elastic arc blocks are spliced ​​together to form a circular plate and close the water outlet hole. The surface of the clamping water bladder abuts against the surface of the sealing membrane.

[0021] By adopting the above technical solution, when the sealing membrane deforms towards the roof due to the air pressure inside the grain silo, the end of the sealing membrane is squeezed against the water bladder. The water pressure inside the water bladder increases, and the water in the water bladder drives the elastic arc block to deform and discharge from the water outlet. The water outlet faces the quicklime block, and the quicklime in the quicklime block reacts with the water to form slaked lime, generating a large amount of heat energy. The thermal expansion and contraction block heats up and expands, pressing against the surface of the sealing membrane. The thermal expansion and contraction block and the positioning plate clamp the two sides of the sealing membrane to form a limit, making it difficult for the end of the sealing membrane to fall out of the limit space, further improving the limit stability of the end of the sealing membrane in the limit space.

[0022] Optionally, an exhaust assembly is connected to the sealing plate. The exhaust assembly includes an exhaust rack and a one-way valve. An exhaust chamber is formed on the surface of the sealing plate, and an exhaust hole communicating with the exhaust chamber is formed on the outer wall of the grain silo. The one-way valve is connected to the inner wall of the exhaust chamber. Air in the exhaust chamber is discharged from the exhaust hole through the one-way valve. A sliding chamber is formed on the inner wall of the rotating chamber for the exhaust rack to slide. The sliding chamber is connected to the exhaust chamber. The exhaust rack meshes with a reinforcing gear. A connecting hole is formed on the surface of the exhaust rack. When the reinforcing gear rotates and drives the exhaust rack to slide away from the sliding chamber, the connecting hole is connected to the exhaust chamber.

[0023] By adopting the above technical solution, the sliding cavity is connected to the exhaust cavity, and the exhaust rack is located in the sliding cavity and seals the exhaust cavity, making it difficult for air in the grain silo to enter the exhaust cavity and to be discharged from the exhaust hole through the one-way valve. When the air pressure in the grain silo increases and drives the sealing membrane to deform towards the roof, the sealing membrane drives the reinforcing gear to rotate. The reinforcing gear meshes with the exhaust rack, causing the exhaust rack to slide away from the sliding cavity. The connecting hole connects to the exhaust cavity, making the sealing effect of the exhaust rack on the exhaust cavity disappear. The air in the grain silo passes through the exhaust cavity, the connecting hole, and the one-way valve in sequence and is discharged from the exhaust hole, thereby reducing the pressure in the grain silo and making the inner wall of the grain silo less likely to crack due to excessive air pressure, thus extending the service life of the grain silo.

[0024] Optionally, the exhaust assembly also includes a warning whistle, which is connected to the inner wall of the exhaust chamber. The warning whistle is located on the side of the one-way valve away from the inner cavity of the grain bin, and the air inlet of the warning whistle faces the air outlet of the one-way valve.

[0025] By adopting the above technical solution, when the air in the exhaust chamber passes through the one-way valve and enters the air inlet of the warning whistle, the warning whistle will sound due to the air impact, thereby alerting the user to control the air pump in time, so that the air pressure in the grain silo cavity is not too high, thus extending the service life of the grain silo.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The installation of sealing membrane, sealing plate and sealing pipe. The sealing membrane restricts the flow of air towards the top of the grain warehouse and forces the air to fully contact the grain under the sealing membrane, thereby improving the ventilation efficiency of the grain warehouse and ensuring that the grain at the bottom of the grain warehouse is not prone to moisture and mold. Users do not need to increase the suction power of the air pump to improve the ventilation efficiency of the grain warehouse, reduce energy consumption, and thus reflect the concept of energy saving.

[0028] 2. The reinforced ring is designed to clamp the outer ring of the ring and the inner wall of the sealing cavity to form a limit on both sides of the sealing membrane, making it difficult for the edge of the sealing membrane to detach from the sealing cavity, thereby improving the sealing stability of the sealing membrane for the grain in the grain warehouse.

[0029] 3. The air supply pipe and elastic block are designed so that the air in the air supply channel can enter the inner cavity of the reinforcing ring bladder through the inner cavity of the air supply pipe. The reinforcing ring bladder is pressurized and expanded and presses against the surface of the sealing membrane, further improving the clamping force between the reinforcing ring bladder and the sealing membrane.

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] This application discloses a low-energy-consumption circulating ventilation system. (Refer to...) Figure 1 The low-energy circulating ventilation system includes an air pump 1 bolted to the outer wall of the grain silo 2, a sealing device 3, multiple air outlet pipes 4 welded to the inner wall of the grain silo 2 at intervals, and multiple air inlet pipes 5 welded to the inner wall of the grain silo 2 at intervals. The air outlet pipes 4 and air inlet pipes 5 are located on opposite sides of the inner wall of the grain silo 2. The height of both the air outlet pipes 4 and the air inlet pipes 5 is equal to the height of the grain surface line of the grain silo 2. Multiple air inlets are spaced apart on the outer wall of the grain silo 2, and each air inlet corresponds to and is connected to an air inlet pipe 5. Multiple air vents are spaced apart on the outer wall of the air inlet pipe 5. The suction end of the air pump 1 is connected to the inner cavity of multiple air outlet pipes 4. Multiple air inlets 2 are spaced apart on the outer wall of the air outlet pipes 4. The air pump 1 drives outside air to enter the inner cavity of the air inlet pipe 5 through the air inlet. The air in the air inlet pipe 5 enters the inner cavity of the grain silo 2 through the air inlet 1. The air passes through the grain in the grain silo 2 and enters the inner cavity of the air outlet pipe 4 through the air inlet 2. The air in the inner cavity of the air outlet pipe 4 is discharged by the air pump 1, thereby supplying air to the grain silo 2. The sealing device 3 is connected to the inner wall of the grain silo 2. The sealing device 3 can restrict the air flow in the grain silo 2 to the roof.

[0038] Reference Figure 2The sealing device 3 includes a sealing membrane 31, a sealing plate 32, a sealing tube 33, and a reinforcing component 34. The sealing plate 32 is fixed to the inner wall of the grain silo 2 by bolts. The sealing plate 32 is located above the grain surface line of the grain silo 2. The sealing plate 32 has a sealing cavity 321 for the sealing tube 33 to be embedded. The sealing tube 33 includes a positioning tube 331 and a reinforcing ring 332. The material of the reinforcing ring 332 can be rubber or silicone. In this embodiment, the material of the reinforcing ring 332 is rubber, which has a certain deformation capacity. The inner ring of the reinforcing ring 332 is coaxially fixed to the outer circumference of the positioning tube 331, and the outer ring of the reinforcing ring 332 can press against the surface of the sealing membrane 31.

[0039] Reference Figure 1 and Figure 2 When the sealing membrane 31 is laid on the top surface of the grain in the grain silo 2, and the circumferential edge of the sealing membrane 31 is embedded in the sealing cavity 321, the sealing tube 33 is embedded in the sealing cavity 321. The outer ring of the reinforcing ring 332 and the inner wall of the sealing cavity 321 clamp the two sides of the sealing membrane 31 to form a limit, thereby limiting the circumferential edge of the sealing membrane 31 in the sealing cavity 321. When the air in the air inlet pipe 5 enters the inner cavity of the grain silo 2 through the air inlet one, the sealing membrane 31 seals the grain in the grain silo 2, making it difficult for the air to flow towards the roof of the grain silo 2. This causes the air in the grain silo 2 to pass through the food and enter the air outlet pipe 4 through the air inlet two, so that the food in the grain silo 2 can fully contact the air, improve the ventilation efficiency of the grain silo 2, and ensure that the grain at the bottom of the grain silo 2 is not prone to dampness and mold. Users do not need to increase the suction power of the air pump 1 to improve the ventilation efficiency of the grain silo 2, reducing energy consumption and thus reflecting the concept of energy saving.

[0040] Reference Figure 2 and Figure 3 The reinforcing component 34 can increase the clamping force of the sealing membrane 31 in the sealing cavity 321. The reinforcing component 34 includes an air supply pipe 341, a reset elastic element 342, a reinforcing gear 343, a reinforcing plate 344, a positioning plate 345, a reinforcing piston 346, an elastic ring 347, a limiting elastic element 348, and multiple elastic blocks 349. The sealing plate 32 has a rotating cavity 322 for the reinforcing gear 343 to rotate.

[0041] Reference Figure 3 and Figure 4The reinforcing plate 344 is welded and fixed to the surface of the reinforcing gear 343. The positioning plate 345 is slidably connected to the surface of the reinforcing plate 344. The sliding direction of the positioning plate 345 is perpendicular to the axis of the reinforcing gear 343. A limiting space 3441 is left between the positioning plate 345 and the reinforcing plate 344 for the end of the sealing film 31 to be embedded. The limiting elastic element 348 can be a compression spring or a tension spring. In this embodiment, the limiting elastic element 348 is a compression spring with a certain deformation capacity. One end of the limiting elastic element 348 in the elastic direction is fixed to the surface of the reinforcing plate 344, and the other end of the limiting elastic element 348 in the elastic direction is fixed to the surface of the positioning plate 345. The limiting elastic element 348 has the elastic force to drive the positioning plate 345 to slide closer to the reinforcing plate 344, and the surface of the positioning plate 345 and the surface of the reinforcing plate 344 tend to clamp the two sides of the sealing film 31.

[0042] Reference Figure 2 and Figure 3 The sealing plate 32 has an air supply channel 323 on its surface, which connects to the rotating cavity 322. The reinforcing piston 346 can be made of rubber or silicone. In this embodiment, the reinforcing piston 346 is made of rubber, which has a certain deformation capacity. The reinforcing piston 346 is slidably connected to the inner wall of the air supply channel 323 near the rotating cavity 322. The surface of the reinforcing piston 346 has a toothed groove 3461 that meshes with the reinforcing gear 343. One end of the air supply pipe 341 is rotatably connected to the inner wall of the air supply channel 323 away from the rotating cavity 322. The other end of 341 faces the sealing cavity 321. The rotation axis of the air supply pipe 341 and the axis of the reinforcing gear 343 are parallel to each other. The reset elastic element 342 can be a torsion spring or a tension spring. In this embodiment, the reset elastic element 342 is a torsion spring, which has a certain deformation capability. One end of the reset elastic element 342 in the elastic direction is fixed on the inner wall of the air supply channel 323, and the other end of the reset elastic element 342 in the elastic direction is fixed on the rotation axis of the air supply pipe 341. The reset elastic element 342 has the tendency to drive the air supply pipe 341 to rotate in a direction closer to the sealing cavity 321.

[0043] Reference Figure 2 The elastic ring 347 can be made of rubber or silicone. In this embodiment, the elastic ring 347 is made of rubber and has a certain deformation capability. The inner ring of the elastic ring 347 is coaxially fixed on the outer wall of the air supply pipe 341, and the outer ring of the elastic ring 347 is fixed on the inner wall of the air supply channel 323. The elastic ring 347 seals the air supply channel 323, so that the air in the air supply channel 323 can stably enter the inner cavity of the air supply pipe 341.

[0044] Reference Figure 2The elastic block 349 can be made of rubber or silicone. In this embodiment, the elastic block 349 is made of rubber and has a certain deformation capability. The surface of the reinforcing ring 332 is provided with an air supply hole 3321 embedded at the end of the air supply pipe 341. The air supply hole 3321 is connected to the inner cavity of the reinforcing ring 332. Multiple elastic blocks 349 are spaced apart and connected to the inner wall of the air supply hole 3321. Multiple elastic blocks 349 are spliced ​​together to form a circular plate and close the air supply hole 3321.

[0045] Reference Figure 2 and Figure 3 When the sealing tube 33 is installed, the air supply tube 341 is driven to rotate away from the sealing cavity 321, and the sealing tube 33 is embedded in the sealing cavity 321. The outer ring of the reinforcing ring 332 and the inner wall of the sealing cavity 321 clamp the two sides of the sealing membrane 31 to form a limit. When the air supply tube 341 is released, the elastic force of the reset elastic element 342 drives the air supply tube 341 to rotate closer to the sealing cavity 321. The end of the air supply tube 341 is squeezed and deformed by the elastic block 349 and embedded in the air supply hole 3321. The air supply tube 341 connects the air supply channel 323 and the inner cavity of the reinforcing ring 332.

[0046] Reference Figure 2 and Figure 4 Simultaneously, the end of the sealing membrane 31 is embedded in the limiting space 3441. The elastic force of the limiting elastic element 348 drives the positioning plate 345 to slide towards the reinforcing plate 344. The surfaces of the positioning plate 345 and the reinforcing plate 344 clamp the two sides of the sealing membrane 31 to form a limiting position. When the air pressure inside the grain silo 2 increases, causing the sealing membrane 31 to deform towards the roof, the air pressure in the grain silo 2 drives the end of the sealing membrane 31 to slide towards the sealing cavity 321, bringing the reinforcing plate 344 closer to the sealing cavity 321. The reinforcing plate 344 is connected to the surface of the reinforcing gear 343, carrying... The reinforcing gear 343 rotates on the inner wall of the rotating cavity 322. The tooth groove 3461 on the reinforcing piston 346 meshes with the tooth surface of the reinforcing gear 343, driving the reinforcing piston 346 to slide on the inner wall of the air supply channel 323. The air pressure in the air supply channel 323 increases, and the air in the air supply channel 323 enters the inner cavity of the reinforcing ring bladder 332 through the air supply pipe 341. The outer ring of the reinforcing ring bladder 332 is pressurized and expands and presses against the surface of the sealing membrane 31, making it less likely for the sealing membrane 31 to shift within the sealing cavity 321, thereby improving the sealing stability of the sealing membrane 31 for the food in the grain silo 2.

[0047] Reference Figure 4 and Figure 5A clamping component 6 is connected to the reinforcing plate 344. The clamping component 6 can improve the clamping force of the end of the sealing membrane 31 within the limiting space 3441. The clamping component 6 includes a clamping water bladder 61, a quicklime block 62, a thermal expansion and contraction block 63, and multiple elastic arc blocks 64. The clamping water bladder 61 can be made of rubber or silicone. In this embodiment, the clamping water bladder 61 is made of rubber and has a certain deformation capacity. The clamping water bladder 61 is fixed on the surface of the reinforcing plate 344 facing the limiting space 3441. The clamping water bladder 61 is located at the end of the reinforcing plate 344 away from the reinforcing gear 343. One end of the quicklime block 62 is fixed to the clamping water bladder 61 facing the reinforcing gear 343. On one side, the quicklime block 62 is fixed at the other end to the thermal expansion and contraction block 63. The thermal expansion and contraction block 63 can be made of nylon or rubber. In this embodiment, the thermal expansion and contraction block 63 is made of nylon and has a certain coefficient of thermal expansion. The water-pressing bag 61 has a water outlet 611 on its surface facing the quicklime block 62. The water outlet 611 is connected to the inner cavity of the water-pressing bag 61. The elastic arc block 64 can be made of rubber or silicone. In this embodiment, the elastic arc block 64 is made of rubber and has a certain deformation capability. Multiple elastic arc blocks 64 are fixed at intervals on the inner wall of the water outlet 611. Multiple elastic arc blocks 64 are spliced ​​together to form a circular plate and close the water outlet 611.

[0048] Reference Figure 4 When the sealing membrane 31 drives the reinforcing plate 344 close to the sealing cavity 321, the surface of the sealing membrane 31 presses against the surface of the water bladder 61, the water pressure inside the water bladder 61 increases, the water inside the water bladder 61 compresses the elastic arc plate and deforms, the sealing effect of the elastic arc plate on the water outlet 611 disappears, the water inside the water bladder 61 impacts the quicklime block 62 through the water outlet 611, the quicklime in the quicklime block 62 reacts with the water to form slaked lime and generates a large amount of heat energy, the thermal expansion and contraction block 63 heats up and expands and presses against the surface of the sealing membrane 31, making it difficult for the end of the sealing membrane 31 to detach from the limiting space 3441, thereby improving the limiting stability of the sealing membrane 31 in the limiting space 3441.

[0049] Reference Figure 5An exhaust assembly 7 is connected to the sealing plate 32. The exhaust assembly 7 can discharge overpressurized air inside the grain silo 2. The exhaust assembly 7 includes a warning whistle 71, an exhaust elastic element 72, an exhaust rack 73, and a one-way valve 74. An exhaust chamber 324 is opened on the surface of the sealing plate 32 and penetrates the surface of the sealing plate 32. An exhaust hole 21 communicating with the exhaust chamber 324 is opened on the outer wall of the grain silo 2. The exhaust chamber 324 connects the exhaust hole 21 and the inner cavity of the grain silo 2. The one-way valve 74 is installed on the inner wall of the exhaust chamber 324, and the warning whistle 71 is installed on the exhaust chamber 324. On the inner wall of the grain silo 2, the warning whistle 71 is located on the side of the one-way valve 74 away from the inner cavity of the grain silo 2. The air inlet of the warning whistle 71 faces the air outlet of the one-way valve 74. Air in the grain silo 2 enters the exhaust chamber 324. The air in the exhaust chamber 324 impacts the air inlet of the warning whistle 71 through the one-way valve 74, causing the warning whistle 71 to emit a sound. At the same time, air is discharged from the exhaust hole 21, realizing the discharge of overpressured air in the grain silo 2. This alerts the user to control the operation of the air pump 1 in time, so that the inner cavity of the grain silo 2 is not prone to cracking due to excessive air pressure, thereby extending the service life of the grain silo 2.

[0050] Reference Figure 5 The inner wall of the rotating cavity 322 is provided with a sliding cavity 325 for the exhaust rack 73 to slide. The exhaust rack 73 meshes with the reinforcing gear 343. The sliding cavity 325 is connected to the exhaust cavity 324. The sliding direction of the exhaust rack 73 is parallel to the height direction of the grain bin 2. The exhaust elastic element 72 can be a compression spring or a tension spring. In this embodiment, the exhaust elastic element 72 is a compression spring with a certain deformation capability. One end of the exhaust elastic element 72 in the elastic direction is connected to the inner wall of the sliding cavity 325, and the other end of the exhaust elastic element 72 in the elastic direction is fixed to the exhaust rack 73. The exhaust elastic element 72 has the elastic force to drive the exhaust rack 73 to slide towards the sliding cavity 325, and the exhaust rack 73 has the tendency to close the exhaust cavity 324.

[0051] Reference Figure 5 The exhaust rack 73 has a connecting hole 731 on its surface. The connecting hole 731 passes through the outer wall of the exhaust rack 73 along its own axis. The axis of the connecting hole 731 is parallel to the length direction of the exhaust chamber 324. When the sealing membrane 31 drives the reinforcing plate 344 to rotate towards the sealing chamber 321, it drives the reinforcing gear 343 to rotate, which drives the exhaust rack 73 to slide away from the sliding chamber 325. The connecting hole 731 connects to the exhaust chamber 324, thereby opening the exhaust chamber 324. The overloaded air in the grain bin 2 enters the exhaust chamber 324. The air in the exhaust chamber 324 enters the one-way valve 74 through the connecting hole 731. The one-way valve 74 drives the air to impact the warning whistle 71 and then discharges it from the exhaust hole 21, thereby releasing the overloaded air in the grain bin 2.

[0052] The implementation principle of a low-energy-consumption circulating ventilation system in this application embodiment is as follows: A sealing membrane 31 is laid on the top surface of the grain in the grain silo 2, and the circumferential edge of the sealing membrane 31 is embedded in the sealing cavity 321. The sealing pipe 33 is embedded in the sealing cavity 321. The outer ring of the reinforcing ring 332 and the inner wall of the sealing cavity 321 clamp the two sides of the sealing membrane 31 to form a limit, thereby limiting the circumferential edge of the sealing membrane 31 within the sealing cavity 321. When the air in the air inlet pipe 5 enters the inner cavity of the grain silo 2 through the air inlet 1, the sealing membrane 31 seals the grain in the grain silo 2, making it difficult for the air to flow towards the roof of the grain silo 2. This causes the air in the grain silo 2 to pass through the food and enter the air outlet pipe 4 through the air inlet 2, so that the food in the grain silo 2 is in full contact with the air, improving the ventilation efficiency of the grain silo 2 and ensuring that the grain at the bottom of the grain silo 2 is not prone to dampness and mold. Users do not need to increase the suction power of the air pump 1 to improve the ventilation efficiency of the grain silo 2, reducing energy consumption and thus embodying the concept of energy saving.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
