Description

Technical Field

[0001] This application relates to the field of grain storage, and in particular to a five-sided temperature-controlled storage ventilation system. Background Technology

[0002] Grain storage is a continuation of agricultural cultivation. Storage technology has developed along with agriculture. With the development of primitive agriculture, agricultural production has reached a certain scale, and there is a surplus of grain. Grain processing has gradually developed into storage. Grain warehouses are an important part of grain storage technology. Grain gates, as an indispensable part of grain warehouses, are used to keep the grain in the warehouse and prevent grain leakage.

[0003] Utility model patent CN215454100U discloses a five-sided temperature-controlled grain storage system, including a storage chamber, a ventilation system, and a temperature control system. The ventilation system includes a distributed main air duct located at the bottom of the storage chamber, with several branch air ducts arranged along the height of the storage chamber. The temperature control system includes an airtight air conditioner located outside the storage chamber, comprising an air supply outlet corresponding to the clearance above the storage chamber and a return air outlet connected to one end of a return air duct. The other end of the return air duct is connected to the upper end of at least one branch air duct serving as a return air channel. An air inlet valve is installed at the upper end of each branch air duct serving as an air inlet channel, and an electric actuator is installed on one side of the air inlet valve. The control box is electrically connected to the electric actuator. The ventilation and temperature control systems enable the flow of cool air within the main and branch air ducts, facilitating cooling of the internal space of the storage chamber.

[0004] However, inside the storage silo, the grain near the edge is in direct contact with the inner wall, especially at the grain outlet. Heat from outside the silo is transferred to the inside through the wall, and there are no ventilation ducts in these edge areas. The grain is easily heated and bacteria can grow, leading to grain damage. Summary of the Invention

[0005] To protect food, this application provides a five-sided temperature-controlled storage ventilation system.

[0006] The five-sided temperature-controlled warehouse ventilation system provided in this application adopts the following technical solution:

[0007] A five-sided temperature-controlled storage ventilation system includes a storage body, a sandwich panel, an upper air duct, and a lower air duct. The storage body has a receiving cavity, and the outer wall of the storage body has a grain outlet connected to the receiving cavity. The sandwich panel, the upper air duct, and the lower air duct are all fixedly connected to the inner wall of the receiving cavity. The sandwich panel has a connecting air duct. The upper air duct is connected to the upper end of the connecting air duct, and the lower air duct is connected to the lower end of the connecting air duct. The upper air duct is arranged circumferentially along the inner wall of the receiving cavity. There are multiple sandwich panels, which are evenly spaced along the extension direction of the upper air duct. Adjacent sandwich panels abut against each other. The lower air duct is arranged around the grain outlet above the grain outlet.

[0008] By adopting the above technical solution, the sandwich panel circumferentially covers the inner wall of the receiving cavity. The grain is located on the inner periphery of the sandwich panel. The sandwich panel separates the grain from the inner wall of the silo and introduces cold air into the sandwich panel, reducing the probability of external heat contact with the grain and causing bacteria to grow on the grain. The lower air duct removes heat from the vicinity of the grain outlet, reducing the probability of grain damage near the grain outlet and protecting the grain.

[0009] Preferably, it also includes a lifting plate, which is slidably connected to the inner wall of the receiving cavity, and the lifting plate is used to cover the grain outlet.

[0010] By adopting the above technical solution, the lifting plate separates the grain in the receiving cavity from the grain outlet, making it less likely for the grain to enter the grain outlet during storage, reducing the probability of external heat contact with the grain and causing bacteria to grow on the grain, thus protecting the grain.

[0011] Preferably, it further includes a first guide block, which is fixedly connected to the inner wall of the receiving cavity. The upper end of the first guide block is provided with a first guide groove, and the lifting plate is slidably connected to the groove wall of the first guide groove.

[0012] By adopting the above technical solution, the first guide groove guides the sliding of the lifting plate and reduces the obstruction of the grain at the bottom of the lifting plate to the up and down sliding of the lifting plate, so that the lifting plate can slide up and down stably.

[0013] Preferably, it also includes a hinge shaft and a cover door. The outer wall of the silo body is provided with an installation groove. The bottom of the installation groove is connected to the grain outlet. The height of the inner wall facing upwards from the grain outlet decreases as it moves away from the lifting plate. The hinge shaft is rotatably connected to the groove wall of the installation groove around its own axis. The hinge shaft is located on the outer periphery of the grain outlet. The rotation axis of the hinge shaft is vertical. One end of the cover door is fixedly connected to the outer wall of the hinge shaft. The cover door is used to cover the upper part of the grain outlet.

[0014] By adopting the above technical solution, the hinge shaft rotates, which drives the cover door to rotate. The cover door is used to separate part of the grain outlet from the external space, reducing the entry of external hot air into the grain outlet and protecting the grain.

[0015] Preferably, it further includes a lead screw and a connecting block. The lead screw is rotatably connected to the bottom of the first guide groove around its own axis. The rotation axis of the lead screw is vertical. The connecting block is fixedly connected to the outer wall of the lifting plate. The connecting block is provided with a connection port. The lead screw is threadedly connected to the inner wall of the connection port.

[0016] By adopting the above technical solution, the screw rotation control fixed block moves up and down along the length of the screw, which facilitates the control of the lifting plate movement.

[0017] Preferably, it further includes a first synchronous pulley, a second synchronous pulley, and a synchronous belt. The housing is provided with a connecting channel, the two ends of which are respectively connected to the mounting groove and the first guide groove. The first synchronous pulley is coaxially fixedly connected to the outer wall of the lead screw, the second synchronous pulley is coaxially fixedly connected to the outer wall of the hinge shaft, and the synchronous belt is sleeved on the outer periphery of the first and second synchronous pulleys. The connecting channel is used for the synchronous belt to pass through.

[0018] By adopting the above technical solution, the hinge shaft rotates while the screw rotates through the synchronous wheel and synchronous belt. This allows the lifting plate to cover the grain outlet when the covering door covers part of the grain outlet, and the grain to be discharged from the bottom of the covering door along the inclined direction of the grain outlet, reducing the probability of bacteria growth in the grain outlet. When the covering door is opened, the lifting plate slides downward to facilitate grain discharge.

[0019] Preferably, it further includes a second guide block, a first spring, a sliding plate, and a cover plate. The second guide block is fixedly connected to the outer wall of the silo body. The upper end of the second guide block is provided with a second guide groove. The lower end of the first spring is fixedly connected to the bottom of the second guide groove. The upper end of the first spring is fixedly connected to the sliding plate. The sliding plate slides in the second guide groove. The end of the cover door away from the lifting plate is fixedly connected to an abutment plate. The lower end of the cover plate abuts against the upper end of the sliding plate, and the upper end of the cover plate abuts against the lower end of the abutment plate. The cover plate and the cover plate are used to jointly cover the grain outlet.

[0020] By adopting the above technical solution, the cover plate and the shielding plate together complete the full coverage of the grain outlet, separating the grain outlet from the external space, reducing the probability of external heat coming into contact with the grain, reducing bacterial growth, and protecting the grain.

[0021] Preferably, the system further includes a first blocking block and a second blocking block. The inner wall of the grain outlet is provided with an air outlet, and the lower inner wall of the grain outlet is provided with an air inlet. The air outlet is connected to the lower air duct via an air outlet pipe, and the air inlet is connected to the lower air duct via an air inlet pipe. The first blocking block is slidably connected to the inner wall of the air outlet pipe and is used to control the opening and closing of the lower air duct. The first blocking block has an air outlet channel, with both ends of the air outlet channel connected to the lower air duct and the air outlet pipe, respectively. Air in the lower air duct enters the air outlet pipe through the air outlet channel. The second blocking block is slidably connected to the inner wall of the air inlet pipe and is used to control the opening and closing of the air inlet pipe. The second blocking block has an air inlet channel, with both ends of the air inlet channel connected to the air inlet pipe and the lower air duct, respectively. Air in the grain outlet enters the lower air duct through the air inlet channel.

[0022] By adopting the above technical solution, when grain is discharged from the outlet, the first blocking block blocks the air outlet pipe, and the second blocking block blocks the air inlet pipe. The air enters the connecting ventilation duct along the lower air duct. When the lifting plate covers the outlet, the covering door and the cover plate cover the outlet. The movement of the first blocking block connects the air outlet channel, and the movement of the second blocking block connects the air inlet channel. The air flows from the lower air duct through the air outlet channel, air outlet pipe, air outlet, grain outlet, air inlet, air inlet pipe, air inlet channel, and lower air duct in sequence before entering the connecting ventilation duct, which carries away the heat in the outlet and protects the grain.

[0023] Preferably, it further includes a limiting plate, a second spring, and a first pull rope. The limiting plate is located on the side of the first blocking block near the air outlet and is fixedly connected to the inner wall of the air outlet pipe. The second spring is located between the limiting plate and the first blocking block, with one end of the second spring fixedly connected to the limiting plate and the other end of the second spring fixedly connected to the limiting plate. The hopper body is provided with a first wire passage, which connects to the second guide groove and the air outlet pipe. One end of the first pull rope is fixedly connected to the first blocking block, and the other end of the first pull rope is fixedly connected to the sliding plate.

[0024] By adopting the above technical solution, the second spring and the first pull rope work together to control the movement of the first blocking block. When the sliding plate slides down, the air outlet channel is connected, and when the sliding plate slides up, the air outlet channel is blocked, which facilitates operation.

[0025] Preferably, it also includes a first filter and a second filter. The first filter is coaxially fixedly connected to the inner wall of the air outlet, and the second filter is coaxially fixedly connected to the inner wall of the air inlet. There are two air outlets, one of which has a greater height than the other, and the opening of the other air outlet faces the second filter.

[0026] By adopting the above technical solution, the first and second filters reduce the amount of impurities entering the lower air duct from the grain outlet. At the same time, the air outlet cleans the surface of the second filter, reducing the probability of impurities clogging the second filter.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The sandwich panel covers the inner wall of the receiving cavity circumferentially. The grain is located on the inner circumference of the sandwich panel. The sandwich panel separates the grain from the inner wall of the silo and introduces cold air into the sandwich panel to reduce the probability of external heat contact with the grain, which would cause bacteria to grow on the grain. The lower air duct removes heat from the vicinity of the grain outlet, reducing the probability of grain damage near the grain outlet and protecting the grain.

[0029] 2. As the hinge shaft rotates, the screw is driven to rotate through the synchronous pulley and synchronous belt. When the cover door covers part of the grain outlet, the lifting plate covers the grain outlet, and the grain is discharged from the bottom of the cover door along the inclined direction of the grain outlet, reducing the probability of bacteria growth in the grain outlet. When the cover door is opened, the lifting plate slides down to facilitate grain discharge.

[0030] 3. When grain is discharged from the outlet, the first blocking block blocks the air outlet pipe, and the second blocking block blocks the air inlet pipe. The air enters the connecting ventilation duct along the lower air duct. When the lifting plate covers the outlet, the covering door and the cover plate cover the outlet. The first blocking block moves to connect the air outlet channel, and the second blocking block moves to connect the air inlet channel. The air enters the connecting ventilation duct from the lower air duct in sequence through the air outlet channel, air outlet pipe, air outlet, grain outlet, air inlet, air inlet pipe, air inlet channel, and lower air duct, thus carrying away the heat in the outlet and protecting the grain.

When the first spring 42 causes the sliding plate 43 to move upward, the second pull rope 564 pulls the second blocking block 561 against the elastic force of the third spring 563. The second blocking block 561 is located inside the air inlet pipe 54, blocking the air inlet passage 5611. When the cover plate 44 abuts against the sliding plate 43, the sliding plate 43 moves downward, the second pull rope 564 loosens, and the third spring 563 causes the second blocking block 561 to slide away from the fixed plate 562. When the end of the second blocking block 561 away from the fixed plate 562 abuts against the inner wall of the lower air duct 23, the air in the grain outlet 12 enters the lower air duct 23 from the air inlet passage 5611.

[0060] The implementation principle of a five-sided temperature-controlled storage ventilation system in this application embodiment is as follows: When grain needs to be discharged, the cover plate 44 is removed, impurities in the grain outlet 12 are discharged, the first spring 42 causes the sliding plate 43 to move upward, the first pull rope 554 pulls the first blocking block 551 to move, blocking the air outlet channel 5511, the second pull rope 564 pulls the second blocking block 561 to move, blocking the air inlet channel 5611, the air flows along the lower air duct 23 and is discharged from the connecting ventilation duct 211, the cover door 36 is opened, the lifting plate 32 slides downward, and the grain is discharged from the grain outlet 12. When the grain discharge is completed... Afterwards, the cover plate is closed, the lifting plate 32 slides upward, and the remaining grain in the grain outlet 12 is discharged from under the cover plate. The cover plate 44 is installed, the sliding plate 43 moves downward, the first pull rope 554 and the second pull rope 564 are relaxed, the second spring 553 pushes the first blocking block 551 to move, the air outlet duct 5511 is opened, the third spring 563 pushes the second blocking block 561 to move, the air inlet duct 5611 is opened, the air enters the grain outlet 12 from the lower air duct 23 and then returns to the lower air duct 23 and is discharged from the connecting air duct 211, removing the heat in the grain outlet 12 and protecting the grain.

[0061] 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.
