Description

Technical Field

[0001] This utility model belongs to the technical field of grain storage equipment, and relates to a sealing component for grain silo doors. Background Technology

[0002] The airtightness of grain silos is crucial, as it is closely related to the effectiveness of pest control, storage costs, and the overall insulation and airtightness of the silo. Good silo door sealing effectively prevents the entry of humid air, avoiding moisture and mold growth on the grain. Since grain naturally contains moisture, a sealed environment reduces moisture exchange, keeping it dry. Furthermore, it minimizes heat exchange, maintaining a stable internal temperature and preventing spoilage from high temperatures or condensation from low temperatures. If the grain becomes infested with insects, gaseous insecticides are needed for fumigation. During fumigation, the silo door must be effectively sealed to prevent toxic gases from escaping into the atmosphere. A well-sealed door also improves the effectiveness of fumigation and reduces the need for chemical pesticides.

[0003] Currently, grain warehouse doors are sealed using solid rubber strips installed around the perimeter. The rubber's elasticity presses against the door or window frame for a tight seal. However, this method is prone to deformation and aging, resulting in a short lifespan. Once the rubber strip ages and deforms, it loses its airtightness. Furthermore, the large contact area between the door leaf and the sealant prevents close contact and compression, leading to poor airtightness and insulation. Therefore, this sealing method fails to achieve the required airtightness due to the aging and deformation of the rubber strips. Summary of the Invention

[0004] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a sealing component for grain warehouse doors. The technical problem to be solved by this utility model is: how to improve the sealing performance of grain warehouse doors.

[0005] The purpose of this utility model can be achieved through the following technical solution: a sealing element for a grain warehouse door, the sealing element including an installation part for installation on the grain warehouse door, a buffer part provided at one end of the installation part, an air bladder provided inside the buffer part, characterized in that the end of the buffer part away from the installation part is provided with an inner lip and an outer lip in the shape of an flared mouth, the inner lip and the outer lip are angular, and the two outer ends of the inner lip and the outer lip extend beyond the two sides of the buffer part.

[0006] In this design, the inner and outer lips are flared, with their outer ends extending beyond the sides of the buffer section. This allows the inner surfaces of the inner and outer lips to easily contact the door frame, increasing the contact area and improving the sealing performance of the grain silo door. An airbag is installed inside the buffer section to enhance the compression deformation capacity of the seal and the resilience of the sealing structure. When the grain silo door is closed, the inner and outer lips deform in conjunction with the buffer section, and the elasticity of the airbag further ensures a tighter fit between the inner and outer surfaces of the inner and outer lips and the door frame, thus improving the sealing performance of the grain silo door.

[0007] In the aforementioned sealing element for a grain silo door, the width of the inner side of the inner lip is greater than the width of the inner side of the outer lip. The inner lip is located inside the outer lip and is closer to the interior of the grain silo than the outer lip. Increasing the width of the inner side of the inner lip increases the contact area between the inner lip and the door frame, thereby improving the sealing effect of the grain silo door.

[0008] In the aforementioned sealing element for a grain silo door, the inner surface of the inner lip and the inner surface of the outer lip form an angle greater than 135°. The inner surfaces of the inner and outer lip are inclined, and when the grain silo door is closed, the inner surfaces of the inner and outer lip contact the door frame sequentially from the outside in, with the outer edges of the inner and outer lip contacting the door frame more tightly.

[0009] In the aforementioned sealing component for a grain silo door, the width of the buffer portion on both sides is greater than the width of the mounting portion on both sides. This greater width allows the buffer portion to deform laterally when the grain silo door is closed, resulting in a tighter fit between the inner and outer lips and the door frame.

[0010] In the aforementioned sealing component for a grain storage door, the cross-section of the mounting portion is square, and the cross-section of the airbag is circular.

[0011] In one of the aforementioned sealing components for grain storage doors, the sealing component is annular and has arc-shaped corners.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. In this design, the inner and outer lips are flared out and the two outer ends of the inner and outer lips extend beyond the sides of the buffer section, making it easy for the inner surface of the inner lip and the inner surface of the outer lip to contact the door frame. This prevents the seal from tilting in one direction and increases the contact area with the door frame, thus improving the sealing performance of the grain warehouse door.

[0014] 2. In this solution, when the grain silo door is closed, the inner and outer lips deform with the buffer part. Combined with the elasticity of the airbag, the inner surface of the inner lip and the inner surface of the outer lip fit more tightly with the door frame, thus improving the sealing performance of the grain silo door.

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] Example

[0025] like Figure 1 and Figure 2 As shown, the grain warehouse door includes a door body 2 and a door frame 3. The door frame 3 is installed on the wall, and the door body 2 is rotatably installed on the door frame 3. In this embodiment, the door body 2 adopts an outward opening method, that is, the door body 2 rotates to the side outside the grain warehouse to open. A sealing element 1 is installed on the door body 2. The overall shape of the sealing element 1 is the same as that of the door body 2, which is annular, and the four corners of the sealing element 1 are arc-shaped. In this embodiment, there are two sealing elements 1, forming a secondary seal, which further improves the sealing effect of the grain warehouse door.

[0026] like Figure 3 and Figure 4 As shown, when the grain warehouse door is closed, the sealing strip abuts against two planar sealing plates 3a1 and 3a2 on the door frame 3.

[0027] like Figure 5-7As shown, the sealing element 1 includes a mounting part 1a for installation on the grain silo door. The mounting part 1a has a square cross-section and is installed in the groove 2a of the door body 2. One end of the mounting part 1a is provided with a buffer part 1b. An air bladder 1c with a circular cross-section is provided inside the buffer part 1b. The two sides of the buffer part 1b are arc-shaped, and the width of the two sides of the buffer part 1b is greater than the width of the two sides of the mounting part 1a.

[0028] At the end of the buffer section 1b furthest from the mounting section 1a, there are flared inner lips 1d and outer lips 1e. The inner lips 1d and outer lips 1e are angular, and their outer ends extend beyond the sides of the buffer section 1b. The inner side width of the inner lip 1d is greater than the inner side width of the outer lip 1e. The inner lip 1d is located inside the outer lip 1e, and is closer to the inside of the grain silo than the outer lip 1e. Increasing the inner side width of the inner lip 1d increases the contact area between the inner lip 1d and the door frame 3, thereby improving the sealing effect of the grain silo door.

[0029] The inner surface of the inner lip 1d forms an angle with the inner surface of the outer lip 1e, and the angle is greater than 135°. In this embodiment, the angle is 150°.

[0030] In this embodiment, the inner lip 1d and the outer lip 1e are flared, and the two outer ends of the inner lip 1d and the outer lip 1e extend beyond the sides of the buffer part 1b, making it easy for the inner side of the inner lip 1d and the inner side of the outer lip 1e to contact the door frame 3, and increasing the contact area with the door frame 3, thereby improving the sealing performance of the grain silo door. An airbag 1c is provided in the buffer part 1b to enhance the compression deformation capability of the sealing element 1 and the resilience of the sealing structure. When the grain silo door is closed, the inner lip 1d and the outer lip 1e deform with the buffer part 1b, and the elasticity of the airbag 1c makes the inner side of the inner lip 1d and the inner side of the outer lip 1e fit more tightly with the door frame 3, thereby improving the sealing performance of the grain silo door.

[0031] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0032] Although this document frequently uses terms such as 1. sealing element; 1a. mounting part; 1b. buffer part; 1c. airbag; 1d. inner lip; 1e. outer lip; 2. door body; 2a. groove; 3. door frame; 3a. sealing plate, etc., the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
