Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sealing and heat insulation, in particular to a sealing and heat insulation structure for granary doors and windows. BACKGROUND

[0002] Food safety is always a major issue related to the national economy and people's livelihood. With the continuous expansion of people's demand for green grain and oil food, grain storage technology is developing in the direction of "green and healthy" and "environmental protection and low carbon". The "four-in-one" upgrading new technology mainly based on nitrogen gas conditioning and grain cold ventilation has been widely applied. The airtight and heat insulation performance of the granary is one of the important indicators of the storage performance, which is related to the application effect and cost of the storage technology. The airtight and heat insulation performance of the early construction of the granary flat warehouse is generally poor, and the nitrogen gas conditioning process is serious. The leakage leads to poor gas conditioning effect and frequent air supplement, resulting in high storage cost, which cannot meet the requirements of green storage technology such as gas conditioning storage. Therefore, improving the airtight and heat insulation performance of the existing granary is crucial for the green and safe storage of grain.

[0003] At present, the sealing and heat insulation structure used for the doors and windows of the granary generally sets rubber material between the door frame and the door and window, and the sealing strip is mostly made of elastic material such as silicone rubber. However, after a long time of use, the sealing strip is prone to extrusion deformation, and it is difficult to restore to its original shape after deformation, so that gaps will be generated when the door and window are closed again, which cannot achieve better heat insulation and sealing effect, and cannot assist the resetting of the deformation of the sealing strip.

[0004] Therefore, we propose a sealing and heat insulation structure for granary doors and windows. SUMMARY

[0005] In view of the shortcomings of the prior art, the present application provides a sealing and heat insulation structure for granary doors and windows, which solves the problem that the sealing strip is prone to extrusion deformation after a long time of use, and thus cannot achieve better heat insulation and sealing effect.

[0006] To achieve the above purpose, the present application realizes the following technical scheme: a sealing and heat insulation structure for granary doors and windows, comprising a sealing frame and a sealing window, the front surface of the sealing frame is slidably provided with a sliding frame, and the inside of the sliding frame is movably provided with a sealing window.

[0008] The front surface of the push-pull frame is rotatably provided with a control knob, and one end of the control knob penetrates the push-pull frame and extends into the inside of the push-pull frame, and the front surface of the sealing window is fixedly provided with a connecting frame, and one end of the control knob is rotatably connected with the inside of the connecting frame.

[0009] Preferably, the upper and lower surfaces of the back surface of the push-pull frame are fixedly provided with sliding frames, and the upper and lower surfaces of the front surface of the sealing frame are respectively provided with sliding grooves matched with the sliding frames.

[0010] Preferably, the bottom of the front surface of the push-pull frame is fixedly provided with a mounting frame, and one side of the inside of the mounting frame is fixedly provided with an air pump, and the output end of the air pump is in communication with the inside of the first sealing air bag and the second sealing air bag through a flexible air guide pipe.

[0011] Preferably, one end of the control knob is threadedly connected with the inside of the push-pull frame, and a sealing gasket is arranged between the surface of the control knob and the inside of the push-pull frame.

[0012] Preferably, the four peripheries of the back surface of the push-pull frame are fixedly provided with fixed sleeves, and the inside of each of the four fixed sleeves is slidably provided with a movable column, one end of the movable column is fixedly connected with the front surface of the sealing window, and the surface of the movable column is further sleeved with a spring.

[0013] Preferably, the flexible air guide pipe is in communication with the inside of the first sealing air bag and the second sealing air bag by penetrating the fixed sleeve and the movable column.

[0014] Preferably, the other side of the inside of the mounting frame is fixedly provided with a gas charging and discharging bag, the inside of the gas charging and discharging bag is in communication with the inside of the push-pull frame, the inside of the push-pull frame is fixedly provided with a closed glass, and the push-pull frame, the sealing window and the sealing frame are all made of heat-breaking bridge aluminum profile.

[0015] Preferably, the interior of the hollow glass is filled with helium, and the interior of the gas charging and discharging bag is also filled with helium. By filling the interior of the hollow glass with helium, the conduction of cold or hot air from the outside is isolated by the hollow glass inside the sealed window, and the low-density helium filled in the interior of the hollow glass further improves the heat insulation effect of the sealed window. In addition, by filling helium between the sliding frame and the sealed window, on the one hand, the airtightness of the connection between the sealed window and the sealed frame is ensured, and on the other hand, the heat insulation effect of the sealed window is effectively improved.

[0016] Preferably, the working process of the grain bin door and window sealing and heat insulation structure specifically includes the following steps:

[0017] Step a1: when the door and window of the grain bin are closed, the sliding frame is driven to slide to the front of the sealing frame by the upper and lower sliding frames, and then the control knob is rotated clockwise to move one end of the control knob to one side of the sealing window, and the control knob is used to push the sealing window to the inside of the sealing frame.

[0018] Step a2: during the process of pushing the sealing window into the interior of the sealing frame by one end of the control knob, the helium in the gas charging and discharging bag enters between the sliding frame and the sealing window, and after the back surface of the sealing window contacts the back surface of the inner wall of the connecting groove, the sliding frame and the sealing window are filled with a helium atmosphere;

[0019] Step a3: after the sealing window is pushed into the connecting groove in the interior of the sealing frame, the two sealing rings on the back surface of the sealing window and the first sealing gas bag enter the interior of the first sealing groove. At this time, the output end of the gas pump sends air into the interior of the first sealing gas bag and the second sealing gas bag through the flexible air guide pipe. The first sealing gas bag and the second sealing gas bag are opened during the filling of the air. The first sealing gas bag is opened in the interior of the first sealing groove, and the first sealing gas bag pushes the two sealing rings to the two sides of the inner wall of the first sealing groove, so that the two sealing rings are tightly attached to the interior of the first sealing groove. At the same time, the second sealing gas bag is also opened in the interior of the annular groove, and one side of the second sealing gas bag enters the interior of the second sealing groove, completing the sealing connection between the sealing window and the sealing frame.

[0020] Compared with the prior art, the following beneficial effects are achieved:

[0021] 1. By sliding the sliding frame on the front surface of the sealing frame, and sealing and heat insulating the interior of the sealing frame with the sealing window movably arranged in the interior of the sliding frame, compared with the opening and closing mode of the hinge hinge, the sliding mode can not only improve the sealing effect between the sealing window and the sealing frame, but also facilitate the opening and closing of the grain bin door and window.

[0022] 2、By setting two sealing strips on the back of the sealing window, setting a first sealing air bag between the two sealing strips, and setting a second sealing air bag on the outer circumferential surface of the sealing window, the first sealing air bag is expanded in the inside of the first sealing groove, the first sealing air bag pushes the two sealing rings to the two sides of the inner wall of the first sealing groove respectively, so that the two sealing rings are tightly fitted with the inside of the first sealing groove, and the second sealing air bag is also expanded in the inside of the annular groove, one side of the second sealing air bag enters the inside of the second sealing groove, the sealing cooperation between the second sealing air bag and the second sealing groove further improves the air tightness of the connection between the sealing window and the sealing frame, the hollow glass arranged in the sealing window insulates the conduction of cold and hot air from the outside, and the low-density helium filled in the hollow glass further improves the heat insulation effect of the sealing window. The first sealing air bag pushes the sealing ring and the sealing cooperation in the inside of the first sealing groove, solves the problem that the sealing ring is deformed after long-term use, and further causes the sealing ring and the first sealing groove to be unable to effectively seal and cooperate.

[0023] 3、By setting a gas charging and discharging bag in the inside of the mounting frame, the sealing window is pushed into the inside of the sealing frame by the control handle, the helium in the gas charging and discharging bag enters between the push-pull frame and the sealing window, and after the sealing connection between the sealing window and the sealing frame is completed, the helium atmosphere is filled between the push-pull frame and the sealing window.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application. Embodiment 1

[0033] Please refer to Figure 1 and Figure 2 As shown in the drawings, a sealing and heat insulation structure for granary doors and windows comprises a sealing frame 1 and a sealing window 2. The front surface of the sealing frame 1 is slidingly provided with a push-pull frame 3, and the inside of the push-pull frame 3 is movably provided with the sealing window 2. The upper and lower surfaces of the back surface of the push-pull frame 3 are fixedly provided with sliding frames 4. The upper and lower surfaces of the front surface of the sealing frame 1 are respectively provided with sliding grooves 5 matched with the sliding frames 4. The upper and lower sliding frames 4 drive the push-pull frame 3 to slide left and right on the front surface of the sealing frame 1. The sealing window 2 movably provided in the push-pull frame 3 seals and insulates the inside of the sealing frame 1. Compared with the opening and closing mode of the hinge, the sliding mode can not only improve the sealing effect between the sealing window 2 and the sealing frame 1, but also facilitate the opening and closing of the granary doors and windows.

[0034] Please refer to Figures 1 to 5As shown, further, the inside of the push-pull frame 3 is fixedly provided with a limiting frame 6, and the inner wall of the limiting frame 6 is in sliding connection with the outer peripheral surface of the sealing window 2. The back surface of the sealing window 2 is fixedly provided with two sealing rings 7, and the opposite sides of the two sealing rings 7 are fixedly provided with a first sealing air bag 8. The outer peripheral surface of the sealing window 2 is further provided with an annular groove, and the inside of the annular groove is fixedly provided with a second sealing air bag 9. The inside of the sealing frame 1 is provided with a connecting groove 10 matched with the sealing window 2. The back surface of the inner wall of the connecting groove 10 is provided with a first sealing groove 11, and the peripheral surface of the inner wall of the connecting groove 10 is further provided with a second sealing groove 12. The inside of the sealing window 2 is fixedly provided with hollow glass 13, and the hollow glass 13 is composed of two symmetrical glass located inside the sealing window 2. Helium is filled between the two glass. The hollow glass 13 inside the sealing window 2 is used to isolate the conduction of cold and hot air from the outside, and the low-density helium filled in the hollow glass 13 is used to further improve the heat insulation effect of the sealing window 2.

[0035] Please refer to Figure 7 As shown, further, the bottom of the front surface of the push-pull frame 3 is fixedly provided with a mounting frame 14, and one side of the inside of the mounting frame 14 is fixedly provided with an air pump 15. The output end of the air pump 15 is in communication with the inside of the first sealing air bag 8 and the second sealing air bag 9 through flexible air guide pipes.

[0036] It should be noted that when the sealing window 2 and the sealing frame 1 are connected in sealing cooperation, the push-pull frame 3 is controlled to move to the front surface of the sealing frame 1, and then the sealing window 2 inside the push-pull frame 3 is pushed into the connecting groove 10 inside the sealing frame 1. The two sealing rings 7 on the back surface of the sealing window 2 and the first sealing air bag 8 enter the inside of the first sealing groove 11. At this time, the output end of the air pump 15 is controlled to send air into the inside of the first sealing air bag 8 and the second sealing air bag 9 through the flexible air guide pipes. The first sealing air bag 8 and the second sealing air bag 9 are expanded during the filling process of the air. The first sealing air bag 8 is expanded in the inside of the first sealing groove 11. The first sealing air bag 8 pushes the two sealing rings 7 to the two sides of the inner wall of the first sealing groove 11 respectively, so that the two sealing rings 7 are tightly fitted with the inside of the first sealing groove 11. At the same time, the second sealing air bag 9 is also expanded in the inside of the annular groove. One side of the second sealing air bag 9 enters the inside of the second sealing groove 12. The sealing cooperation between the second sealing air bag 9 and the second sealing groove 12 further improves the air tightness between the sealing window 2 and the sealing frame 1. The hollow glass 13 arranged in the sealing window 2 isolates the conduction of cold and hot air from the outside. The low-density helium filled in the hollow glass 13 further improves the heat insulation effect of the sealing window 2. The first sealing air bag 8 pushes the sealing ring 7 and the sealing cooperation in the inside of the first sealing groove 11, which solves the problem that the sealing ring 7 is deformed after a long time of use, and further causes the sealing ring 7 and the first sealing groove 11 to be unable to effectively seal and cooperate. Embodiment 2:

[0037] As shown in Figure 4 As a further supplement to the scheme in Embodiment 1, the front of the push-pull frame 3 is provided with a control knob 16, and one end of the control knob 16 penetrates the push-pull frame 3 and extends to the inside of the push-pull frame 3. The front of the sealing window 2 is fixedly provided with a connecting frame 17, and one end of the control knob 16 is rotatably connected to the inside of the connecting frame 17. One end of the control knob 16 is threadedly connected to the inside of the push-pull frame 3, and a sealing gasket is arranged between the surface of the control knob 16 and the inside of the push-pull frame 3.

[0038] It should be noted that when connecting the sealing window 2 and the sealing frame 1, the control knob 16 is rotated clockwise, and one end of the control knob 16 moves to one side of the sealing window 2. The sealing window 2 is pushed by one end of the control knob 16 to move to the inside of the sealing frame 1, thereby achieving the sealing and heat insulation treatment of the barn door and window.

[0039] As shown in Figure 4 and Figure 5 Further, the back of the push-pull frame 3 is fixedly provided with a fixed sleeve 18 around, and the inside of the four fixed sleeves 18 is slidably provided with a movable column 19, one end of the movable column 19 is fixedly connected to the front of the sealing window 2, and the surface of the movable column 19 is further sleeved with a spring, wherein the two ends of the spring are respectively fixedly connected to the rear end of the fixed sleeve 18 and the front of the sealing window 2. The flexible air guide pipe communicates with the inside of the first sealing air bag 8 and the second sealing air bag 9 by penetrating the fixed sleeve 18 and the movable column 19. The other side of the inside of the mounting frame 14 is fixedly provided with a gas charging and discharging bag 20, and the inside of the gas charging and discharging bag 20 communicates with the inside of the push-pull frame 3. The inside of the push-pull frame 3 is fixedly provided with a closed glass, and the push-pull frame 3, the sealing window 2 and the sealing frame 1 are all made of heat insulation bridge aluminum profiles. The heat insulation bridge aluminum profile can avoid the heat conduction of metal and reduce the heat insulation effect. The heat insulation bridge aluminum profile can effectively block the heat conduction performance of metal and improve the heat insulation effect of the door and window.

[0040] It needs to be explained that when the sealing connection between the sealing window 2 and the sealing frame 1 is completed, the sealing window 2 inside the push-pull frame 3 is pushed into the inside of the sealing frame 1 by controlling the handle 16, and then the first sealing air bag 8 and the second sealing air bag 9 are respectively expanded in the inside of the first sealing groove 11 and the second sealing groove 12 by using the air pump 15, so as to complete the sealing connection between the sealing window 2 and the sealing frame 1. In the process of sliding into the inside of the sealing frame 1, the helium in the inside of the charge-discharge bag 20 enters between the push-pull frame 3 and the sealing window 2, and after the sealing connection between the sealing window 2 and the sealing frame 1 is completed, the helium atmosphere is filled between the push-pull frame 3 and the sealing window 2. The helium is used to fill between the sealing window 2 and the push-pull frame 3, which on the one hand ensures the airtightness of the connection between the sealing window 2 and the sealing frame 1, and on the other hand effectively improves the heat insulation effect of the sealing window 2. Embodiment 3:

[0041] Please refer to Figures 1 to 7 The working process of the sealing and heat insulation structure for the door and window of the granary is disclosed in the embodiment, and specifically includes the following steps:

[0042] Step a1: when the door and window of the granary are closed, the push-pull frame 3 is driven to slide to the front of the sealing frame 1 by the upper and lower sliding frames 4, and then the control handle 16 is rotated clockwise to move one end of the control handle 16 to one side of the sealing window 2, and the one end of the control handle 16 pushes the sealing window 2 to move to the inside of the sealing frame 1;

[0043] Step a2: in the process of pushing the sealing window 2 into the inside of the sealing frame 1 by one end of the control handle 16, the helium in the inside of the charge-discharge bag 20 enters between the push-pull frame 3 and the sealing window 2, and after the back surface of the sealing window 2 contacts with the back surface of the inner wall of the connecting groove 10, the helium atmosphere is filled between the push-pull frame 3 and the sealing window 2;

[0044] Step a3: after the sealing window 2 is pushed into the connecting groove 10 in the inside of the sealing frame 1, the two sealing rings 7 on the back surface of the sealing window 2 and the first sealing air bag 8 enter the inside of the first sealing groove 11, and at this time, the output end of the air pump 15 sends air into the inside of the first sealing air bag 8 and the second sealing air bag 9 through the flexible air guide pipe, and the first sealing air bag 8 and the second sealing air bag 9 are expanded in the process of filling with air. The first sealing air bag 8 is expanded in the inside of the first sealing groove 11, the first sealing air bag 8 pushes the two sealing rings 7 to the two sides of the inner wall of the first sealing groove 11 respectively, so that the two sealing rings 7 are tightly attached to the inside of the first sealing groove 11, and at the same time, the second sealing air bag 9 is also expanded in the inside of the annular groove, one side of the second sealing air bag 9 enters the inside of the second sealing groove 12, and the sealing connection between the sealing window 2 and the sealing frame 1 is completed.
