Description

Technical Field

[0001] The invention relates to the technical field of shallow cylindrical silos, in particular to an airtight structure of a floor-standing shallow cylindrical silo door. Background Art

[0002] For a long time, the structure of the shallow round silo was relatively simple and the air tightness was extremely poor. Whenever the grain depot was fumigated or filled with nitrogen, the operation would be difficult due to the insufficient air tightness of the silo door. The air tightness of the silo door refers to the sealing performance of the silo door to the gas in the silo. As an important part of the silo, the importance of air tightness of the shallow round silo door is self-evident. During the grain storage period, the air temperature affects the silo temperature, and the silo temperature affects the grain temperature. The degree of influence of the air temperature on the silo temperature mainly depends on the thermal insulation performance of the silo, and the thermal insulation performance of the silo is closely related to the air tightness of the silo door. The poor air tightness of the silo door will exchange gas and moisture with the external environment. The temperature in the silo will rise due to the influence of the high temperature outside. Under the action of wind pressure difference and thermal pressure difference, it will penetrate into the silo through the silo door gap, affecting the local temperature and moisture content of the grain pile. If it is not handled in time, it will cause the grain pile to heat up and mold.

[0003] Moreover, most of the current airtight designs rely on insulated sealed doors. Due to external wind and rain, their airtight structures are prone to aging, resulting in a decrease in airtight performance and inconvenience in maintenance and replacement. Summary of the invention

[0037] See also Figure 1-Figure 8 As shown, the embodiment of the present application provides an airtight structure of a floor-standing shallow round warehouse door, which is mainly used for sealing a floor-standing shallow round warehouse door 30. The floor-standing shallow round warehouse includes a warehouse body 10, and the warehouse body 10 has a door frame 11. The top of the warehouse door 30 is an arc-shaped tongue and groove, and the top of the door frame 11 matches the arc-shaped tongue and groove, and a first sealing gasket 33 is fixed at the arc-shaped tongue and groove at the top of the door frame 11, which is used to form a sealing structure with the top of the door frame 11; the two sides of the door frame 11 have third sealing gaskets 35, which are used to form a sealing structure with the two sides of the warehouse door 30; the bottom of the door frame 11 has a threshold 12, and the side of the threshold 12 facing the warehouse door 30 has a second sealing gasket 34, which is used to form a sealing structure with the bottom of the warehouse door 30. After closing the warehouse door 30, an effective sealing structure is formed between the warehouse door 30 and the door frame 11 through the first sealing gasket 33, the second sealing gasket 34 and the third sealing gasket 35, which can well improve the airtightness and solve the problem of poor sealing of the warehouse door in the prior art. The arc-shaped tongue-and-groove sealing structure designed on the top makes the door more airtight when closed, and prevents food from being stuffed into the gap.

[0038] Specifically, the first sealing gasket 33 , the second sealing gasket 34 and the third sealing gasket 35 may all be made of EPDM rubber to enhance aging resistance such as ozone resistance, heat resistance, corrosion resistance, etc.

[0039] Specifically, the door frame 11 is wedge-shaped and is cast with concrete, with the end surface of the thick end facing the warehouse door 30, and the second sealing gasket 34 is fixed to the end surface.

[0040] See also Figure 1-Figure 2 As shown, in some embodiments, the airtight structure of the floor-standing shallow round warehouse door further includes a heat-insulating sealed door 20, and the heat-insulating sealed door 20 and the warehouse door 30 are respectively located on the outer side and the inner side of the door frame 11. The heat-insulating sealed door 20 and the warehouse door 30 form a two-layer sealing structure, which can also resist external wind and rain, and protect the inner warehouse door 30.

[0041] It should be noted that the inner side of the door frame 11 is the interior of the ground-standing shallow silo, which is used to store grain.

[0042] See also Figure 2 As shown, in some embodiments, the bin door 30 is a double-door structure consisting of two arc-shaped door panels 31. The arc-shaped structure can better resist the pressure from the grain in the bin.

[0043] See also Figure 8 As shown, in a further embodiment, a door gap structure is formed between the two arc-shaped door panels 31, and the door gap structure between the two arc-shaped door panels 31 is a tongue-and-groove structure, wherein the tongue-and-groove of one arc-shaped door panel 31 has an arc-shaped groove, and the tongue-and-groove of the other arc-shaped door panel 31 has an arc-shaped protrusion (toward the grain side), and a fourth sealing gasket 36 is provided between the arc-shaped groove and the arc-shaped protrusion, and the fourth sealing gasket 36 is fixed in the arc-shaped groove. The above design can enhance the air tightness of the door gap structure, and the arc-shaped protrusion is located on the side facing the grain, and the pressure of the grain can be used to compress the above tongue-and-groove sealing structure, further enhancing the sealing.

[0044] See also Figure 7As shown, in some embodiments, the arc door panel 31 is longitudinally divided into a plurality of independent door panel units 32, and a door gap structure is formed between two adjacent door panel units 32, and the door gap structure is a tongue-and-groove structure, wherein the tongue and groove of one door panel unit 32 has an arc-shaped groove, and the tongue and groove of another door panel unit 32 has an arc-shaped protrusion (toward the grain side), and a fourth sealing gasket 36 is provided between the arc-shaped groove and the arc-shaped protrusion, and the fourth sealing gasket 36 is fixed in the arc-shaped groove. The arc door panel 31 is designed to be a plurality of independent door panel units 32, and one of the door panel units 32 can be opened separately, which is more labor-saving and convenient than opening the entire arc door panel 31 at one time, and can withstand certain deformation; when there is still grain in the lower part of the warehouse, the upper door panel unit 32 can be opened to enter the warehouse, while the entire arc door panel 31 must be cleaned of the grain at the bottom before the door leaf can be opened. Furthermore, the sealing structure added between the door panel units 32 can enhance the air tightness of the transverse door gap structure, and the arc-shaped protrusion is located on the side facing the grain, and the pressure of the grain can be used to compress the tongue-and-groove sealing structure, thereby further enhancing the sealing.

[0045] See also Figure 1 , Figure 2 , Figure 6 As shown, in some embodiments, a sealing film 50 is further provided between the thermal insulation sealed door 20 and the warehouse door 30. The sealing film 50, the thermal insulation sealed door 20 and the warehouse door 30 together form a three-layer sealing structure for further enhancing the sealing performance.

[0046] Specific to Figure 6 In the illustrated embodiment, the sealing film 50 is fixed to the door frame 11 through a plastic sealing groove 51 and a rubber tube 52. The plastic sealing groove 51 is fixedly laid around the door frame 11 to form a closed ring, and the rubber tube 52 clamps the sealing film 50 around the plastic sealing groove 51. The structure is simple, easy to disassemble and install, and also convenient to replace.

[0047] Specifically, the plastic sealing groove 51 is fixed to the door frame 11 by screws, and a fifth sealing gasket 53 is provided between the plastic sealing groove 51 and the door frame 11 to enhance the sealing between the plastic sealing groove 51 and the door frame 11 .

[0048] In summary, the beneficial effects of the present invention include:

[0049] 1) The present invention uses innovative design to shape the concrete structure at the top of the door frame 11 into an arc-shaped tongue-and-groove shape, and cleverly embeds EPDM rubber material. This design can effectively solve the problem of poor airtightness at the top of the door frame 11, while avoiding the problem of food particles being embedded in the top gap, and significantly improving the overall sealing performance.

[0050] 2) In order to further enhance the airtightness of the door 30, the present invention particularly adds a bottom threshold 12, and embeds EPDM rubber strips here and between the door 30. In addition, EPDM rubber seals are also installed on the doorposts on both sides of the door frame 11. This series of improvement measures successfully solves the problem of insufficient airtightness at the bottom and both sides of the door 30.

[0051] 3) In order to further improve the airtightness of the door 30, the present invention also innovatively adds a sealing film 50. By simply pressing the sealing film 50 into the plastic sealing groove 51, an additional sealing layer can be quickly formed, which is not only convenient to operate, but also the replacement cost of the sealing film 50 is extremely low, providing additional airtightness protection for the entire door system.
