[0002] In the grain storage process, controlled atmosphere grain storage is a grain storage technology that kills insects and inhibits mildew and delays changes in grain quality. In the process of controlled atmosphere grain storage, vents need to be equipped to adjust the gas ratio and control the gas concentration. For example, the Chinese utility model patent with the authorization announcement number CN218417438U discloses a cantilevered intelligent heat-insulated closed vent for a grain depot, which overcomes the problem of the small opening angle of the existing vent cover and provides a cantilevered intelligent heat-insulated closed vent for a grain depot. The Chinese patent with the publication number CN201015309Y discloses a vent suitable for preventing grain condensation at the air outlet of the earth embankment warehouse, solving the condensation problem of grain at the ridge and vent of the grain pile in the earth embankment warehouse. In actual work, some old warehouses use film to seal the grain pile, and set vents under the pile in the warehouse. When ventilation or air conditioning and strong exhaust operations are performed, it is generally necessary to occupy the passage in the grain warehouse, affecting the operation of the passage in the grain warehouse, and the film sealing docking is required during the air conditioning and strong exhaust operation, which affects the air tightness of the grain pile.

The opening and closing of the elbow is realized by opening and closing the manual valve. The grain pile is generally wrapped with a plastic film when stored. The utility model ingeniously uses the plastic film to cover and seal the opening. When the staff is outside the grain pile, that is, outside the plastic film, the manual valve can be used to open and close, and the elbow can also be disassembled and assembled by uncovering and covering the plastic film.

[0006] The utility model is further configured as follows: the ventilation pipe opening is provided with a first mounting plate, the bent pipe is provided with a second mounting plate, and the first mounting plate and the second mounting plate are fixed by screws.

[0012] The utility model is further configured as follows: the bent pipe is made of a stainless steel pipe.

[0013] The utility model is further configured as follows: the manual valve is a PVC manual valve.

[0014] By adopting the above technical solution, the manual valve is made of PVC.

[0015] The utility model is further configured as follows: it also includes a frame, a magnet is arranged on the frame, and the ventilation pipe opening is made of stainless steel.

[0016] By adopting the above technical solution, when the opening needs to be sealed with a plastic film, the frame is aligned with the opening, and the magnet on the frame is adsorbed on the ventilation pipe opening, so that the plastic film is covered and pressed tightly on the opening of the ventilation pipe opening to achieve sealing. The staff pulls the frame open with force to separate the magnet from the ventilation pipe opening, and the plastic film at the opening can be uncovered.

[0017] The utility model is further configured as follows: a circle of buffer pads is fixed on the frame, and the magnet is located between the buffer pads and the frame.

[0018] By adopting the above technical solution, the buffer pad is used to contact the plastic film, and the material is relatively soft, thereby reducing the damage to the plastic film.

[0019] The utility model is further configured as follows: an adhesive tape is bonded to the buffer pad, and the adhesive tape is bonded to the plastic film.

[0020] By adopting the above technical solution, after the plastic film is untied, in order to prevent the plastic film from affecting the ventilation at the opening, the tape can be adhered to the plastic film, and the position of the frame and the buffer pad can be adjusted to keep a certain distance between the plastic film and the opening.

[0021] The utility model has the beneficial effects that a reserved position is arranged on the side of the grain pile, the ventilation pipe opening is arranged at the reserved position, and the bent pipe is buried under the grain pile, which saves space, does not occupy the granary passage, and does not affect the passage operation.
