Ventilation opening seal thermal insulation door for grain depot

Abstract

The invention discloses a ventilation opening seal thermal insulation door for a grain depot. The ventilation opening seal thermal insulation door for the grain depot comprises a door plate (1), a bounding frame (6), a door frame (4), a hollow sealing strip (5), at least one hinge (2) capable of adjusting the gap between the door frame and the door plate and at least one common compressing hand wheel (3), wherein the hollow sealing strip (5) is connected with the bounding frame (6) in a clamping mode, so that the sealing is reliable, the installation and the replacement are easy, the hinge (2) capable of adjusting the gap between the door frame and the door plate and the common compressing hand wheel (3) adjust the compressing degree of the seal thermal insulation door through screwing in and screwing out the hand wheel (3) according to requirements, and sagging of the door plate (1) is effectively prevented through the pin joint of a first branch part (12), a second branch part (13) and a screw (11) of the hinge (2) capable of adjusting a gap between the door frame and the door plate.

Description

technical field [0001] The invention relates to a vent sealing heat preservation door for a grain depot. Background technique [0002] The vents of the warehouse need to be equipped with sealed doors to control the opening or closing of the vents of the warehouse, so as to facilitate various work activities in the warehouse. At present, the airtight doors commonly used in warehouse vents use movable hinges or fixed hinges to control the opening and closing of the doors. When closing the door, it needs to be manually lifted, adjusted to the correct position and then pressed with the hand wheel, which is time-consuming and laborious, and the door cannot be opened and closed directly by machinery; the airtight door with fixed hinges cannot adjust the gap between the door and the door frame. When sealing, it is easy to cause uneven force and inconsistent deformation of the sealing strips on different sides. After long-term use, due to the aging of the sealing strip material and...

Problems solved by technology

At present, the airtight doors commonly used in warehouse vents use movable hinges or fixed hinges to control the opening and closing of the doors. When closing the door, it needs to be manually lifted, adjusted to the correct position and then pressed with the hand wheel, which is time-consuming and laborious, and the door cannot be opened and closed directly by machinery; the airtight door with fixed hinges cannot adjust the gap between the door and the door frame. When sealing, it is easy to cause uneven force and inconsistent deformation of the sealing strips on different sides. After long-term use, due to the aging of the sealing strip material and the rust and wear of the hinge, the sealing strip on the side close to the hinge cannot be reliably pressed when the door is closed, resulting in ventilation. Mouth won't seal

The sealing strips used in the airtight doors of traditional warehouse vents are generally in the form of solid foam, which requires high pressure when used for a long time, and the sealing state is likely to be unstable and unreliable when used for a long time, and the sealing strips are generally fixed on the door or door frame. Difficult to install and replace

The airtight doors of traditional warehouse vents generally only play a sealing role. The material of the door is relatively thin and generally metal has a good heat conduction effect. In a sealed state, it cannot isolate the internal and external temperatures. Restricted when applied in
