Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] See attached document Figure 1 - Appendix Figure 8 An airtight and heat-insulated green grain storage container technology is disclosed. This technology utilizes an airtight and heat-insulated grain storage container, comprising a container body 100 and a cover 200. An air-supported membrane 300 is installed inside the container body 100, where the grain to be stored is placed for airtight storage. The cover 200 can be completely separated from the container body 100. An airtight zipper 330 is installed at the top of the air-supported membrane 300. After the cover 200 is raised and staggered, the airtight zipper 330 is opened, creating a large opening at the top of the air-supported membrane 300. The grain to be stored is then placed inside the air-supported membrane 300 for isolated storage. The air-supported membrane 300 effectively provides isolation and sealing.

[0029] Multiple lifting rings 340 are also provided on the surface of the air-supported membrane storage 300. The lifting rings 340 can be adapted to the buckle structure inside the box 100, so that the air-supported membrane storage 300 remains in an open state when the inside of the air-supported membrane storage 300 is empty, which facilitates the loading of grain.

[0030] Gas nozzle 320 is arranged on the top and bottom sidewall of the air film bunker 300, through which the air flow can be controlled to flow in the air film bunker 300, ensuring the smooth flow of the air in the air film bunker 300, and the protective gas is introduced to replace the gas generated by the grain respiration, realizing the long-term storage of the grain.

[0031] The discharge port 350 is also arranged on the bottom sidewall of the air film bunker 300, which has a large opening size and is internally provided with a gate plate. When the gate plate inside the discharge port 350 is opened, the grain stored in the air film bunker 300 flows out under the action of gravity, realizing the emptying of the stored grain. After the grain is completely emptied, the air film bunker 300 can be lifted out by suspending multiple lifting rings 340 through hoisting equipment, realizing the replacement and maintenance of the air film bunker 300.

[0032] The air film bunker 300 here does not have the function of heat insulation. In order to avoid the problem of excessive temperature difference between the inner and outer layers of the grain in the container caused by long-term exposure of the container to the sun, which may cause internal condensation and storage safety hazards, a nitrogen protection structure is arranged on the outside of the container. The gas protection structure 400 is arranged on the outside of the box body 100 and the cover body 200.

[0033] The gas protection structure 400 has good heat insulation performance, can greatly reduce heat exchange with the outside world, and has heat insulation and cold preservation effect, solving the problem of internal condensation and storage safety hazards caused by the hot skin and cold core of the internal grain, and reducing the adverse effects of high temperature on the grain.

[0034] Specifically, the gas protection structure 400 includes a mounting panel 410 and a plurality of airtight protection assemblies 420 arranged on the surface of the mounting panel 410. The airtight protection assembly 420 includes a positioning plate 421 and a gas bag 424 fixed to the surface of the positioning plate 421. Nitrogen gas is filled into the gas bag 424, which can control the expansion of the gas bag 424 to the outside and both sides. The two sides of the plurality of gas bags 424 abut against each other to form a gas protection surface. The outside of the container is protected by the plurality of gas protection surfaces, thereby reducing heat transfer and maintaining the relative balance of the internal temperature of the container.

[0035] In this paper, low-temperature nitrogen gas is used as an example. Those skilled in the art can also choose other types of insulating protective gases for insulation protection.

[0036] Further, in order to facilitate the installation and removal of the airtight protection assembly 420, a transversely arranged guide rail 411 is fixed on the surface of the installation panel 410, and a first groove 422 matching the guide rail 411 is formed in the inner wall of the positioning plate 421. The guide rail 411 and the first groove 422 are in an engagement structure. The positioning plate 421 is slid into the guide rail 411 from one side to achieve the installation of multiple positioning plates 421. The installed positioning plate 421 can be in a relatively stable state, avoiding the vertical positioning plate 421 from falling off under the action of external force, and ensuring the relative stability of the positioning plate 421 and the air bag 424 outside the positioning plate 421.

[0037] After sliding the multiple airtight protection assemblies 420 to the predetermined position, the protection gas is pumped into the air bag 424 in the airtight protection assembly 420, the air bag 424 is controlled to expand, and after the air bag 424 expands to a predetermined state, the adjacent two air bags 424 abut against each other, and finally form an overall gas protection surface to achieve the isolation protection of the outside surface of the container.

[0038] In order to realize the pumping of the air bag 424, a second groove 423 is further arranged on the inner side of the positioning plate 421, and a pumping device 440 is arranged in the second groove 423. The protection gas can be unidirectionally pumped into the air bag 424 by the pumping device 440 to control the expansion of the air bag 424.

[0039] Specifically, the pumping device 440 includes a pumping main pipe 441 and multiple pumping branch pipes 442. The pumping branch pipe 442 communicates with the corresponding air bag 424. When the pumping device continuously pumps the gas into the pumping main pipe 441, the gas is pumped into the corresponding air bag 424 from the multiple pumping branch pipes 442, and finally the air bag 424 is controlled to expand.

[0040] A one-way valve can be installed in the pumping branch pipe 442, which can only control the protection gas to be unidirectionally pumped from the pumping main pipe 441 into the air bag 424, avoiding the reverse flow of the gas causing the air bag 424 to shrink.

[0041] With the continuous expansion of the air bag 424, the multiple air bags 424 are pressed against each other, causing the pressure in the air bag 424 to continuously increase. At the same time, the gas in the pumping main pipe 441 gradually increases. By installing a pressure detection element in the air bag 424, the expansion state of the air bag 424 can be judged by detecting the air pressure in the air bag 424. When the pressure detection element detects that the pressure exceeds the set threshold value, the pumping device is controlled to stop pumping the gas into the pumping main pipe 441, avoiding the continuous entry of the gas into the air bag 424, which causes the internal pressure of the air bag 424 to be continuously too large, resulting in damage to the air bag 424.

[0042] At the same time, during long-term storage, some of the air bags 424 may slowly leak gas. When the air bags 424 collapse due to excessive leakage of gas in the air bags 424, the air bags 424 cannot be tightly closed, and cannot play a good isolation effect. At this time, the pumping device is started again to pump protective gas into the corresponding air bag 424 to maintain the good inflation state of the air bag 424.

[0043] During long-term outdoor placement or transportation of the container, the air bags 424 here are easily damaged by external pressure or cutting of sharp substances. When a single air bag 424 is damaged, the gas protection surface is damaged, the heat insulation is empty, and the heat insulation effect cannot be achieved.

[0044] To solve the above problems, the material of the air bag 424 and the related detection control means are improved, as follows.

[0045] First, the air bag 424 here includes a second stretch surface 4242 arranged transversely and a first stretch surface 4241 arranged longitudinally. The extension rate of the material of the first stretch surface 4241 is greater than that of the second stretch surface 4242. During the process of pumping protective gas into the air bag 424, the first stretch surface 4241 is first stretched and lengthened. At this time, the overall air bag 424 gradually thickens, and the width direction, i.e. the transverse width of the second stretch surface 4242, does not change much.

[0046] When one of the plurality of air bags 424 is damaged, the pressure detection element in the air bag 424 detects that the gas pressure in the air bag 424 instantaneously decreases. An electromagnetic valve is also provided in the pumping branch pipe 442. The electromagnetic valve controls the closure of the corresponding electromagnetic valve in the pumping branch pipe 442 to prevent gas from entering the corresponding air bag 424 through the corresponding electromagnetic valve. Subsequently, the pumping device is started again to pump gas into the pumping main pipe 441. The pumped gas can control the remaining air bags 424 to continue to expand. At this time, the second stretch surface 4242 of the air bag 424 is pressed beyond the first set threshold value, and the second stretch surface 4242 is gradually stretched. At this time, the overall width of the air bag 424 gradually increases (the left and right directions in the figure). Figure 8 The plurality of air bags 424 are tightly closed to each other to form a gas protection surface on the outside.

[0047] The air-tight protection assembly 420 here is in sliding connection with the mounting panel 410. The air-tight protection assembly 420 can be forced to move along the position of the defect. The adjacent two air bags 424 can move towards the deflated defect position, and finally fill the existing defect to form a new gas protection surface, achieving efficient heat preservation and insulation.

[0048] Through the above structural design, after a small number of air bags 424 are damaged and deflated, the air bags 424 do not need to be replaced, and only the remaining air bags 424 need to be pumped into gas to control the secondary expansion and widening of the remaining air bags 424, to fill the defects and re-form the gas protection surface to achieve a new balance.

[0049] The first stretching surface 4241 and the second stretching surface 4242 described above are made of different materials or composite materials, and a control layer with different traction elasticities is formed in the inside of different surfaces to control the stretching and deformation of the first stretching surface 4241 and the second stretching surface 4242.

[0050] Further, a plurality of positioning holes 412 are formed on the surface of the mounting panel 410, and a locking workpiece can be locked and fixed with the outer air-tight protection assembly 420 by penetrating the positioning hole 412, to avoid the movement of the air-tight protection assembly 420 and ensure the relative stability of the air-tight protection assembly 420 in the normal state. The positioning holes 412 are arranged on both sides, and a plurality of positioning holes 412 can be arranged at the middle position according to the overall length.

[0051] The positioning holes 412 are arranged on the inner side of the air-tight protection assembly 420, and the air-tight protection assembly 420 is limited by the telescopic positioning element 430. The limiting state of the telescopic positioning element 430 can be changed. When the air bag 424 on the surface of the air-tight protection assembly 420 at the edge position is damaged, the corresponding telescopic positioning element 430 is controlled to cancel the limiting of the air-tight protection assembly 420 at the edge position, to control the expansion of the gas, and finally the plurality of air bags 424 are pressed to push the outermost damaged air bag 424 to a more outer position. The air bag 424 at the adjacent position on the inner side can be positioned at the edge position to achieve limiting protection.

[0052] Meanwhile, the telescopic positioning element 430 is arranged in the sound and light protection structure, and an alarm signal is sent when the telescopic positioning element 430 cancels the limiting of the air-tight protection assembly 420, to remind the surrounding workers, to avoid the unstable air-tight protection assembly 420 at the edge position from causing harm to the surrounding personnel, and to also remind the on-site personnel to disassemble and maintain the air-tight protection assembly 420.

[0053] The telescopic positioning element 430 can be selected as a telescopic structure with an electric telescopic rod, and the limiting block at the end of the electric telescopic rod is controlled to extend into the groove in the air-tight protection assembly 420, to achieve the locking and limiting of the air-tight protection assembly 420. The electric telescopic rod is controlled to retract, and the limiting block is retracted to the initial position and is disengaged from the air-tight protection assembly 420, to facilitate the movement of the air-tight protection assembly 420.

[0054] It should be noted that the pump branch 442 here is selected as a hose structure, which can move synchronously with the movement of the air-tight protection assembly 420 to ensure normal pumping of the protection gas.

[0055] The present application specifically comprises the following steps:

[0056] Step one: arrangement of the air film bunker 300; the cover 200 is opened and the air film bunker 300 is placed inside the box body 100, the upper end of the box body 100 is connected with the multiple lifting rings 340 on the surface of the air film bunker 300 through hoisting equipment, the suspension of the lifting rings 340 is realized, and the multiple lifting rings 340 around are fixed to the inner wall of the inner film 310 to control the opening of the inner film 310; after the arrangement of the inner film 310 is completed, the air-tight zipper 330 is opened, the grain is poured into the air film bunker 300 from the air-tight zipper 330 at the top for storage, the air-tight zipper 330 is closed after the grain is placed, a relatively closed state is formed in the air film bunker 300, and the storage of the grain and the isolation from the outside environment are realized.

[0057] Step two: arrangement of the gas protection structure 400, the multiple air-tight protection assemblies 420 are sequentially passed through the mounting panel 410 from one side, the air-tight protection assembly 420 and the mounting panel 410 are in the state of mutual engagement, and the air-tight protection assembly 420 is slid to the predetermined position, the number of the air-tight protection assemblies 420 is selected according to the width of the unfolding of the air bag 424 on the surface of the air-tight protection assembly 420 and the length of the whole gas protection structure 400.

[0058] The multiple air bags 424 can be arranged in the collapsed state, and the air bag 424 does not need to be inflated in the process of preliminary installation, which is convenient for workers to take, after the multiple air bags 424 are arranged, the air-tight protection assemblies 420 at both sides and the middle predetermined positions are locked and positioned, after the air-tight protection assemblies 420 at the predetermined positions are locked and positioned, the gas is pumped into the multiple air bags 424 synchronously, in this process, the multiple air bags 424 are first gradually thickened, and then gradually widened, the widened air bags 424 are tightly abutted against each other, and finally a dense gas protection surface is formed to realize gas isolation and protection.

[0059] Through the above arrangement, the air bag 424 does not need to be pumped during the preliminary installation, which is convenient for the installation and arrangement of the staff. After the arrangement of the plurality of air-tight protection assemblies 420 is completed, the gas is pumped into the plurality of air bags 424, the expanded air bags 424 push each other to drive the air bags 424 and the inner positioning plates 421 to slide to the predetermined positions, and finally a dense gas protection surface is formed. The arrangement is simple and convenient, the overall arrangement time is reduced, the overall arrangement difficulty is greatly reduced, and the plurality of air bags 424 arranged are tightly abutted. The plurality of air-tight protection assemblies 420 do not need to be fixed, only the outermost and the air-tight protection assemblies 420 at the predetermined points in the middle need to be fixed, the arrangement is simple, the limiting and protection effects are good.

[0060] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
