Description

Technical Field

[0001] This utility model relates to the field of grain storage equipment technology, specifically to an insulated and airtight grain inspection door. Background Technology

[0002] Grain warehouses play a crucial role in national grain reserves, local grain reserves, and grain circulation. As the main channel for grain circulation, their core tasks cover multiple circulation links such as grain receiving, storage, and transportation. Grain warehouse doors, as an important component of grain warehouses, are of great significance in ensuring the normal functioning of grain warehouses.

[0003] In order to ensure the airtightness of the grain silo, existing grain silo doors usually have sealing strips on the door frame and door panel. This ensures that the grain silo has good airtightness when the door panel is closed. In order to ensure that the grain silo door has good durability and corrosion resistance and can adapt to different environmental conditions, the door panel is usually made of metal (steel or aluminum alloy).

[0004] The existing grain warehouse doors have the following problems: the existing sealing strips are usually exposed on the door panel and frame when the door is closed, which is prone to aging or being chewed by rodents and insects, resulting in a decrease in the sealing performance of the grain warehouse door. To address this, we propose an insulated and airtight inspection grain door. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a heat-insulating and airtight grain inspection door. The door seals and insulates the grain silo through a sealing and heat-insulating mechanism. When the door is closed, the sealing ring and sealing ring are not exposed to the outside, which avoids the situation where the sealing performance of the grain silo door will decrease due to the easy aging or being chewed by rodents and insects. Moreover, the heat preservation effect is good and can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat-insulating and airtight grain inspection door, including a door frame, with door panels hinged to the left and right sides of the door frame, and also including a sealing and heat-insulating mechanism;

[0007] The sealing and insulation mechanism includes a baffle, clearance groove, recess, sealing ring, L-shaped groove, mounting groove, sealing ring, and insulation components. The outer surface of each door panel has a recess, and each recess contains a sealing ring. The left side of the right door panel has a baffle, and the right side of the left door panel has a clearance groove. When the two door panels are closed, the front side of the baffle fits against the rear side of the clearance groove. The inner wall of the door frame has an L-shaped groove, and both sides of the L-shaped groove have mounting grooves, each containing a sealing ring. The rear side of each door panel has an insulation component. This sealing and insulation mechanism seals and insulates the grain silo. When the door panels are closed, the sealing ring and sealing ring are not exposed to the outside, preventing the grain silo door from becoming aging or being chewed by rodents or insects, thus ensuring good insulation.

[0008] Furthermore, the insulation component includes a slot and a mounting plate. The rear side of the door panel is provided with a slot, and the rear side of the door panel is installed with a mounting plate by bolts. The front protrusion of the mounting plate is located inside the slot on the same side, which facilitates the installation of the mounting plate and forms a gap.

[0009] Furthermore, the insulation component also includes polyurethane foam, and the gap between the front side of the front protrusion of the mounting plate and the front wall of the groove on the same side is filled with polyurethane foam to facilitate blocking heat conduction.

[0010] Furthermore, the insulation component also includes cavities and nylon thermal insulation strips. The front end protrusion of the mounting plate has uniformly distributed cavities inside, and each cavity is equipped with a nylon thermal insulation strip to facilitate the reduction of heat conduction.

[0011] Furthermore, the front side of the door panel is provided with fixed seats on both the upper and lower sides, and a locking rod is slidably connected between two fixed seats on the same door panel. The front side of the door frame is provided with lock seats on both the left and right sides, and the upper end of the locking rod is slidably connected to the inside of the adjacent lock seats, which facilitates the fixing of the door panel after it is closed.

[0012] Furthermore, the outer surface of the locking rod is provided with a locking block, and the front side of the door panel is provided with a U-shaped groove. The locking blocks are engaged with the interior of the adjacent U-shaped grooves to facilitate the restriction of the locking rod sliding.

[0013] Furthermore, each of the door panels has an observation window on its front side, and the front and back sides of the observation window are equipped with tempered glass. The space between the two tempered glass panes in the same door panel is filled with air or inert gas, which facilitates observation of the conditions inside the grain silo.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This insulated and airtight grain inspection door has the following advantages:

[0015] 1. When the door panel is closed, the two sealing rings are arranged in an alternating pattern. The protruding parts of the sealing rings and sealing rings deform together to fill the gaps between the two door panels and between the door panel and the door frame. At the same time, the front and left sides of the baffle are respectively attached to the rear and right sides of the clearance groove, and the side wall of the L-shaped groove of the door frame is attached to the outer surface of the door panel, protecting the sealing rings and sealing rings. The sealing rings and sealing rings are not exposed to the outside, avoiding the situation where the sealing performance of the grain warehouse door decreases due to the easy aging or being chewed by rodents and insects.

[0016] 2. The polyurethane foam filling the slot has a low thermal conductivity, which can effectively block heat conduction. The mounting plate blocks heat conduction through the internal cavity and the nylon heat insulation strip installed inside the cavity, resulting in good heat preservation effect of the grain silo door.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-8 This embodiment provides a technical solution: a heat-insulating and airtight grain inspection door, including a door frame 1, with door panels 2 hinged to the left and right sides of the door frame 1, and a sealing and heat-insulating mechanism 3. The front side of the door panel 2 has fixed seats 4 on both the upper and lower sides, and a locking rod 5 is slidably connected between two fixed seats 4 on the same door panel 2. The front side of the door frame 1 has lock seats 8 on both the left and right sides, and the upper ends of the locking rods 5 are slidably connected to the interior of adjacent lock seats 8. The outer surface of the locking rods 5 has locking blocks 6. The front side of the door panel 2 has U-shaped grooves 7, and the locking blocks 6 are engaged with the interior of adjacent U-shaped grooves 7. The front side of the door panel 2 has observation windows, and the interior of the observation windows has tempered glass 9 on both the front and rear sides. Air or inert gas is filled between two tempered glass panes 9 on the same door panel 2. The body, staff, and door frame 1 are fixed to the grain silo door opening by bolts or welding. When the two door panels 2 are closed, under the restriction of the fixed seat 4, the locking rod 5 is moved upward by the locking block 6 until the upper end of the locking rod 5 moves into the interior of the adjacent locking seat 8. Then the locking block 6 is rotated so that the locking block 6 can be locked into the interior of the U-shaped groove 7 when it is released. After the locking block 6 is fixed, the upper end of the locking rod 5 is still located inside the locking seat 8, so that the door panel 2 is always in a closed state. When it is necessary to open the door panel 2, the locking block 6 is moved upward and then rotated to release the U-shaped groove 7 from the fixing of the locking block 6. After that, the locking block 6 is released, and the locking rod 5 moves downward until the upper end of the locking rod 5 leaves the interior of the locking seat 8, so that the door panel 2 can be opened. When the door panel 2 is closed, the staff can observe the interior of the grain silo through the tempered glass 9 without opening the door panel 2.

[0028] The sealing and insulation mechanism 3 includes a baffle 31, a clearance groove 32, a groove 33, a sealing ring 34, an L-shaped groove 35, a mounting groove 36, a sealing ring 37, and an insulation component 38 (the sealing ring 34 and the sealing ring 37 are both rubber sealing rings). Grooves 33 are provided on the outer surface of the door panel 2, and sealing rings 34 are provided inside each groove 33. A baffle 31 is provided on the left side of the right door panel 2, and a clearance groove 32 is provided on the right side of the left door panel 2. When the two door panels are closed, the front side of the baffle 31 fits against the rear side of the clearance groove 32. An L-shaped groove 35 is provided on the inner wall of the door frame 1, and mounting grooves 36 are provided on both sides of the L-shaped groove 35. Each door panel 2 has an internal sealing ring 37, and each door panel 2 has a thermal insulation component 38 on its rear side. (The width of the sealing ring 34 is greater than the depth of the groove 33, and the width of the sealing ring 37 is greater than the depth of the mounting groove 36. When the two door panels 2 are closed, the deformation of the protruding parts of the sealing ring 34 and the sealing ring 37 together fills the gap between the two door panels 2 and between the door panel 2 and the door frame 1.) The thermal insulation component 38 includes a groove 381 and a mounting plate 383. Each door panel 2 has a groove 381 on its rear side, and each door panel 2 has a mounting plate 383 (the mounting plate 383 is an aluminum alloy mounting plate 383) installed on its rear side by bolts. The front protrusions of the mounting plate 383 are all located in the groove on the same side. Inside 381, to facilitate heat conduction blocking, the insulation component 38 also includes polyurethane foam 382. The gap between the front side of the protruding front end of the mounting plate 383 and the front wall of the groove 381 on the same side is filled with polyurethane foam 382. The insulation component 38 also includes cavities 384 and nylon thermal insulation strips 385. The interior of the protruding front end of the mounting plate 383 has evenly distributed cavities 384, and each cavity 384 is equipped with a nylon thermal insulation strip 385. When the two door panels 2 are closed, the two sealing rings 34 are staggered. The right side of the left sealing ring 34 is in contact with the left side of the baffle 31, and the left side of the right sealing ring 34 is in contact with the right side of the left door panel 2. The protruding parts of the sealing ring 34 located in the groove 33 and the sealing ring 37 located in the mounting groove 36 are deformed to fill the gap between the two door panels 2 and between the door panel 2 and the door frame 1. At the same time, the front side and left side of the baffle 31 are respectively attached to the rear side and right side of the clearance groove 32. The side wall of the L-shaped groove 35 of the door frame 1 is attached to the outer surface of the door panel 2 to protect the sealing ring 34 and the sealing ring 37. The polyurethane foam 382 filled in the groove 381 has a low thermal conductivity and can effectively block heat conduction. The mounting plate 383 is made of metal (aluminum alloy) and has fast heat conduction. Heat conduction is blocked by the cavity 384 and the internal nylon heat insulation strip 385.

[0029] The working principle of the insulated and airtight inspection grain door provided by this utility model is as follows: The worker and the door frame 1 are fixed to the door opening of the grain silo by bolts or welding. When the two door panels 2 are closed, under the restriction of the fixed seat 4, the locking rod 5 is moved upward by the locking block 6 until the upper end of the locking rod 5 moves into the interior of the adjacent locking seat 8. Then the locking block 6 is rotated so that when the locking block 6 is released, it can be locked into the interior of the U-shaped groove 7. After the locking block 6 is fixed, the upper end of the locking rod 5 is still located inside the locking seat 8, so that the door panel 2 is always in a closed state. When it is necessary to open the door panel 2, the locking block 6 is moved upward and then rotated to release the fixing of the locking block 6 by the U-shaped groove 7. After that, the locking block 6 is released, and the locking rod 5 moves downward until the upper end of the locking rod 5 leaves the interior of the locking seat 8, so that the door panel 2 can be opened. When the door panel 2 is closed, the worker can observe the interior of the grain silo through the tempered glass 9 without opening the door panel 2. When the door panel 2 is closed, the two sealing rings 34 are arranged in an alternating manner. The right side of the left sealing ring 34 is in contact with the left side of the baffle 31, and the left side of the right sealing ring 34 is in contact with the right side of the left door panel 2. The protruding parts of the sealing ring 34 located in the groove 33 and the sealing ring 37 located in the mounting groove 36 are deformed to fill the gap between the two door panels 2 and between the door panel 2 and the door frame 1. At the same time, the front side and the left side of the baffle 31 are in contact with the rear side and the right side of the clearance groove 32, respectively. The side wall of the L-shaped groove 35 of the door frame 1 is in contact with the outer surface of the door panel 2 to protect the sealing rings 34 and 37. The polyurethane foam 382 filled in the groove 381 has a low thermal conductivity and can effectively block heat conduction. The mounting plate 383 is made of metal (aluminum alloy) and has fast heat conduction. Heat conduction is blocked by the cavity 384 and the internal nylon heat insulation strip 385.
