[0001] The present application relates to the field of food storage, and in particular to a film-sealed transverse ventilation system. Background Art

[0002] Granaries are special buildings for storing grain, mainly used to store large amounts of grain. A low temperature environment is more conducive to the storage of grain, and current granaries are generally equipped with ventilation or cooling systems.

[0003] The invention patent with authorization publication number CN105075546A discloses a grain warehouse ventilation system and method, including a temperature and humidity detection device, a ventilation device and a central control module; the temperature and humidity detection device is used to detect the temperature parameters and humidity parameters inside the grain pile, the temperature parameters and humidity parameters of the air in the warehouse and the atmosphere outside the warehouse; the ventilation device includes an upper vent, a lower vent and a fan of the warehouse, and the fan is arranged at the upper vent and / or the lower vent to drive air to flow into or out of the warehouse.

[0004] With regard to the above-mentioned related technologies, the inventor believes that when the fan is installed on the lower vent or the upper vent, the fan supplies air into the warehouse, and the flowing cold air flows toward the top of the warehouse and is discharged from the upper vent, so that the cold air flow cannot fully contact the grain at the bottom of the warehouse, making the ventilation in the warehouse uneven, which can easily cause the grain at the bottom of the warehouse to be susceptible to moisture and mold. Summary of the invention

[0005] In order to improve the problem of uneven ventilation in a warehouse, the present application provides a film-sealed transverse ventilation system.

[0006] The present application provides a membrane-sealed transverse ventilation system, which adopts the following technical solution:

[0007] A film-sealed transverse ventilation system includes a ventilation component and a sealing component. The ventilation component is used for air supply. The ventilation component includes an air inlet pipe arranged on the inner wall of a warehouse and an air outlet pipe arranged on the inner wall of the warehouse. The air inlet pipe and the air outlet pipe are located on opposite inner walls of the warehouse. Wind enters the inner cavity of the warehouse from the air inlet pipe and is discharged from the air outlet pipe. The sealing component includes a sealing film and a sealing member. The sealing member limits the sealing film on the inner wall of the warehouse to form a seal. The sealing film is located above the air outlet pipe and the air inlet pipe.

[0008] By adopting the above technical scheme, grains are piled up in the warehouse, and the sealing member limits the sealing film on the inner wall of the warehouse to form a seal. The sealing film is located above the air inlet pipe and the air outlet pipe, and the air inlet pipe and the air outlet pipe are located on both sides of the inner wall of the warehouse. When the wind discharged from the air inlet pipe moves upward, the sealing film limits the wind from continuing to move upward, driving the wind discharged from the air inlet pipe to fill the gaps between the grains and be discharged from the air outlet pipe, thereby realizing horizontal ventilation in the warehouse, fully contacting the wind with the grain, realizing uniform ventilation in the warehouse, making the grain in the warehouse not easily affected by moisture and mold, thereby improving the grain storage quality in the warehouse.

[0009] Optionally, the seal includes a closed groove tube and a sealing tube arranged on the inner wall of the warehouse, and the closed groove tube is provided with a sealing groove for accommodating the sealing tube. When the end of the sealing film abuts against the inner wall of the sealing groove, the sealing tube is embedded in the sealing groove, and the outer wall of the sealing tube drives the outer wall of the sealing film to press against the inner wall of the sealing groove to form a fixation.

[0010] By adopting the above technical scheme, when the grain in the warehouse needs to be ventilated, the staff will cover the sealing film on the surface of the grain, and the sealing film will be embedded in the sealing groove one by one on all sides, and the sealing tube will be embedded in the sealing groove. The outer wall of the sealing tube drives the outer wall of the sealing film to press against the inner wall of the sealing groove to form a fixation, and the sealing film limits the wind discharged from the air inlet pipe to continue to move upward, so that the wind fully contacts the grain and is discharged from the air outlet pipe, thereby forming horizontal ventilation; when the sealing film is damaged, the staff will force the sealing tube to detach from the sealing groove, so that the limiting effect of the sealing film on the closed groove tube disappears, thereby facilitating the staff to replace the sealing film.

[0011] Optionally, the sealing member further comprises a self-tapping screw, one end of which passes through a closed groove tube and is threadedly connected to the inner wall of the warehouse for fixation.

[0012] By adopting the above technical solution, when the sealed groove pipe needs to be replaced after being used for a long time, the staff unscrews the self-tapping screws to eliminate the limiting effect of the sealed groove pipe on the inner wall of the warehouse, thereby facilitating the staff to replace the sealed groove pipe.

[0013] Optionally, a sliding cavity is opened on the outer wall of the sealed groove tube toward the air inlet tube, and the sliding cavity penetrates the sealed groove tube in the direction away from the air inlet tube. A connecting hole is opened on the outer wall of the air inlet tube toward the sliding cavity, and the connecting hole connects the sliding cavity and the inner cavity of the air inlet tube. A sliding rod is slidably connected to the inner wall of the sliding cavity, and the sliding direction of the sliding rod is close to or away from the sealed tube. The wind in the air inlet tube enters the sliding cavity from the connecting hole and drives the sliding rod to slide in the direction close to the sealed tube, and the outer wall of the sliding rod is pressed against the outer wall of the sealed tube to be fixed.

[0014] By adopting the above technical solution, when the wind in the air inlet pipe enters the sliding cavity from the connecting hole, the wind in the sliding cavity drives the sliding rod to slide in the direction close to the sealing tube, and the outer wall of the sliding rod presses against the outer wall of the sealing tube to form a fixation, so that the sealing tube is not easy to separate from the closed groove tube, thereby improving the connection stability between the sealing tube and the closed groove tube.

[0015] Optionally, an elastic member 1 is connected between the sliding rod and the sealed groove tube, and the elastic force of the elastic member 1 drives the sliding rod to slide in a direction away from the sealing tube.

[0016] By adopting the above technical solution, when the air inlet duct stops ventilating, the driving force of the wind on the sliding rod disappears, and the elastic force of the elastic member drives the sliding rod to slide in the direction away from the sealing tube, thereby realizing automatic resetting of the sliding rod without the need for manual correction by the staff, thereby reducing the use cost of the film sealing horizontal ventilation system.

[0017] Optionally, an exhaust hole is opened on the outer wall of the sliding rod facing the connecting hole, and the exhaust hole passes through the outer wall of the sliding rod. An elastic ball is connected to the end face of the sliding rod facing the sealing tube, and the inner cavity of the elastic ball is connected to the exhaust hole. When the wind in the sliding cavity enters the inner cavity of the elastic ball from the exhaust hole, the elastic ball is deformed, and the outer wall of the elastic ball is pressed against the outer wall of the sealing tube to be fixed.

[0018] By adopting the above technical scheme, when the air inlet pipe is ventilated, the wind in the air inlet pipe enters the sliding cavity from the connecting hole, and the wind in the sliding cavity enters the inner cavity of the elastic ball from the exhaust hole. The elastic ball is inflated and deformed, and the outer wall of the elastic ball presses against the outer wall of the sealing tube. The outer wall of the sealing tube is deformed under force, and the outer wall of the sealing tube drives the outer wall of the sealing film to press against the inner wall of the sealing groove to achieve fixation, so that the sealing film is not easy to separate from the closed groove tube, further improving the connection stability between the sealing film and the closed groove tube.

[0019] Optionally, a magnetic block 1 and a magnetic block 2 are connected to the sealed groove tube, and the magnetic block 1 and the magnetic block 2 attract each other and clamp the end of the sealing film to form a fixation.

[0020] By adopting the above technical solution, magnetic block one and magnetic block two attract each other and press the end of the sealing tube tightly to fix it, so that the end of the sealing film is not easy to separate from the sealed groove tube, further improving the connection stability between the sealing film and the sealed groove tube.

[0021] Optionally, an opening and closing block is slidably connected to the inner wall of the sliding cavity, and the sliding direction of the opening and closing block is close to or away from the axis of the connecting hole. A through hole is opened on the opening and closing block, and the axis of the through hole and the axis of the connecting hole are parallel to each other. The through hole passes through the opening and closing block along its own axis. When the opening and closing block slides in the direction away from the axis of the connecting hole, the opening and closing block separates the sliding cavity and the connecting hole. When the opening and closing block slides in the direction close to the axis of the connecting hole, the connecting hole, the through hole and the sliding cavity are connected in sequence.

[0022] By adopting the above technical solution, when the air inlet pipe is ventilated, the opening and closing block slides in the direction close to the axis of the connecting hole, the connecting hole, the through hole and the sliding cavity are connected in sequence, and the wind in the air inlet pipe passes through the connecting hole, the through hole, the sliding cavity, the exhaust hole and enters the elastic ball in sequence. The inflation amount of the elastic ball is achieved by controlling the sliding distance of the opening and closing block.

[0023] Optionally, the magnetic block 2 and the magnetic block 1 are slidably connected on the sealed groove tube, and the sliding direction of the magnetic block 1 and the magnetic block 2 is close to or away from the sealing tube. A fixed bar is connected between the magnetic block 2 and the opening and closing block. When the sealing film drives the magnetic block 2 and the magnetic block 1 to slide in the direction away from the sealing tube, the fixed bar drives the opening and closing block to slide in the direction close to the axis of the connecting hole, and the connecting hole, the through hole and the sliding cavity are connected in sequence.

[0024] By adopting the above technical solution, when the ventilation rate in the air intake pipe is high, the wind drives the sealing film to expand in the direction away from the grain, and the end of the sealing film drives the magnetic block 1 and the magnetic block 2 to slide in the direction away from the sealing tube, driving the fixed bar to drive the opening and closing block to slide in the direction close to the axis of the connecting hole. The connecting hole, the through hole and the sliding cavity are connected in sequence, realizing the automatic sliding of the opening and closing block without manual control by the staff, thereby further improving the ease of use of the horizontal ventilation system.

[0025] Optionally, a second elastic member is connected between the sealed groove tube and the opening and closing block, and the elastic force of the second elastic member drives the opening and closing block to slide in a direction away from the axis of the connecting hole.

[0026] By adopting the above technical solution, when the air inlet pipe stops ventilating, the pushing force of the sealing film on the magnetic block one and the magnetic block two disappears, and the elastic force of the elastic part two drives the opening and closing block to slide in the direction away from the axis of the connecting hole.

The vacuum pump 13 is installed on the outer wall of the warehouse. The vacuum pump 13 and the air outlet pipe 12 are connected through a pipeline. When the vacuum pump 13 is working, the wind in the air inlet pipe 11 is driven to pass through the inner cavity of the warehouse and the inner cavity of the air outlet pipe 12 in sequence and be discharged from the vacuum pump 13, thereby realizing the horizontal ventilation of the warehouse.

[0038] Reference Figure 2The sealing assembly 2 includes a sealing film 21 and a sealing member 22. The sealing film 21 is made of a PVC film with high tensile strength and is not easily damaged. The sealing member 22 is used to limit the sealing film 21 to the inner wall of the warehouse to form a seal.

The wind fills the gaps between the grains, so that the wind fully contacts the grains. The wind in the inner cavity of the warehouse passes through the inner cavity of the air outlet pipe 12 and is discharged from the vacuum pump 13, thereby realizing the horizontal ventilation of the warehouse, making the grain in the warehouse less susceptible to moisture and mold, thereby improving the storage quality of the grain in the warehouse.

[0054] When the wind in the connecting hole 122 drives the sliding rod 3 to slide in the direction close to the sealing tube 222, the limiting effect of the inner wall of the sliding cavity 2212 on the limiting rod 6 disappears, and the elastic force of the elastic member 37 drives the limiting rod 6 to slide in the direction away from the axis of the exhaust hole 31. The outer wall of the limiting rod 6 abuts against the outer wall of the closed groove tube 221, and the exhaust hole 31, the connecting hole 61 and the sliding cavity 2212 are connected in sequence.
