Abstract

The utility model provides a sealing element for a granary door, and belongs to the technical field of grain storage equipment. It has solved how to improve the leakproofness of granary door. A sealing member for granary door, sealing member including being used for installing the installation department on the granary door, installation department one end be equipped with the buffer portion, the buffer portion in seted up the gasbag, its characterized in that, the one end that the installation department was kept away from to the buffer portion be equipped with inner lip and the outer lip that is flaring form, inner lip and outer lip be the angle form, inner lip and outer lip both ends both sides that surpass the buffer portion. In this scheme, interior lip and outer lip are flaring form and the both sides that both ends of interior lip and outer lip surpassed the buffer make interior lip medial surface and outer lip medial surface contact with the door frame easily, the sealing member that can not be is to one direction skew to increased the area of contact with the door frame, improved the leakproofness of granary door.

Description

Sealing element for granary door Technical Field The utility model belongs to the technical field of grain storage equipment, and relates to a sealing piece for a granary door. Background The air tightness of the granary is of great importance, and the air tightness is closely related to the insecticidal effect of stored grains, the cost of stored grains and the heat preservation and air tightness effect of the granary. If the sealing performance of the granary door is good, the external moist air can be effectively prevented from entering, the grains are prevented from being damped and moldy, the grains contain certain moisture, the sealing environment can reduce the moisture exchange and keep the drying, the heat exchange between the inside and the outside can be reduced, the temperature in the granary is kept stable, and the grains are prevented from deteriorating due to high temperature or dewing at low temperature. If the grain is insect-living, the grain needs to be fumigated and killed by using the gas insecticide, the granary door is required to be sealed effectively during fumigating and killing, toxic gas is prevented from being lost to the atmosphere in a fumigating stage, and meanwhile, the sealing performance of the granary door can improve the insecticidal and fumigating effect and reduce the use of chemical agents. At present, the granary door is sealed by installing solid strip-shaped rubber sealing strips around the door, compacting the door frame or window frame tightly by the elasticity of rubber, the sealing rubber is easy to be extruded and deformed, ageing is short in service life, the rubber strip cannot play an airtight role once ageing is extruded and deformed, the extrusion area of the door leaf and the sealing rubber is large, the door leaf cannot be extruded in close contact with the sealing rubber, and the airtight heat preservation performance is poor. The sealing method can not achieve the required sealing effect in practice due to the aging deformation of the rubber sealing strip. Disclosure of Invention The utility model aims at solving the problems existing in the prior art and provides a sealing piece for a granary door, and the technical problem to be solved by the utility model is how to improve the sealing performance of the granary door. The aim of the utility model can be achieved by the following technical scheme: A sealing member for granary door, sealing member including being used for installing the installation department on the granary door, installation department one end be equipped with the buffer portion, the buffer portion in seted up the gasbag, its characterized in that, the one end that the installation department was kept away from to the buffer portion be equipped with inner lip and the outer lip that is flaring form, inner lip and outer lip be the angle form, inner lip and outer lip both ends both sides that surpass the buffer portion. In the scheme, the inner lip and the outer lip are in a flaring shape, the two outer ends of the inner lip and the outer lip exceed two sides of the buffer part, so that the inner side surface of the inner lip and the inner side surface of the outer lip are easy to contact with the door frame, the contact area between the inner lip and the door frame is increased, the sealing performance of the granary door is improved, the air bag is arranged in the buffer part, the extrusion deformation capacity of the sealing piece and the rebound resilience of the sealing structure are improved, when the granary door is closed, the inner lip, the outer lip and the buffer part deform, and the inner side surface of the inner lip and the inner side surface of the outer lip are more tightly attached to the door frame by matching with the elasticity of the air bag, and the sealing performance of the granary door is improved. In one such seal for a grain bin door, the inner lip has a greater width than the inner lip. The inner lip is located the inboard of outer lip, and the inner lip compares and is close to the granary inside with outer lip more, increases the medial surface width of inner lip can increase the area of contact of inner lip and door frame, improves the sealed effect of granary door. In the sealing element for the granary door, the inner side face of the inner lip forms an included angle with the inner side face of the outer lip, and the included angle is larger than 135 degrees. The inner side surface of the inner lip and the inner side surface of the outer lip are obliquely arranged, when the granary door is closed, the inner side surface of the inner lip and the inner side surface of the outer lip are sequentially contacted with the door frame from outside to inside, and the outer edges of the inner side surface of the inner lip and the inner side surface of the outer lip are more tightly contacted with the door frame. In the sealing member for the granary door, the width of the two sides of the buffer part is larger th
