Description

Technical Field

[0001] The present invention relates to the technical field of underground container grain storage, and particularly relates to a container grain storage device and a grain storage method with a polymer air film bladder type. Background Art

[0002] The multi-functional container grain storage device is transformed based on the standard container structure, usually made of high-strength steel or composite materials, and has three core properties: airtightness, waterproofness, and heat insulation. The multi-functional container grain storage device solves the pain points of traditional grain storage by integrating core technologies such as environmental control, gas management, and intelligent monitoring, and shows significant advantages in fields such as emergency support, logistics optimization, and military logistics. With technological iteration and policy support, it will become an important infrastructure for ensuring food security and promote the upgrading of grain storage towards intelligence, greenness, and modularity.

[0003] However, during the use of existing multi-functional container grain storage devices, grains are directly stored inside the container. When directly storing, the grains are in direct contact with the inner wall of the container, lacking the protection of a heat insulation layer. The change of external temperature and humidity may be directly conducted to the inside of the grain pile, resulting in local condensation or temperature rise, accelerating the mildew and aging of grains. The sealing performance of ordinary containers is difficult to reach the fully enclosed level, and external pests will invade through gaps or ventilation openings, causing grain contamination.

[0004] There are related invention patents regarding container grain storage, specifically as follows: Chinese Patent Application No.: CN202311137474.6, Invention Patent Name: A Movable Container-Type Grain Storage Device. This invention includes multiple container grain storage units, a unit transfer vehicle, a gantry crane, a grain storage warehouse shelf, and a traction mechanism; the unit transfer vehicle includes a movable box frame, a first guiding sliding frame, and a driving mechanism; a sliding table for carrying the container grain storage unit is slidably arranged on the first guiding sliding frame, multiple guiding protrusions are arranged at the bottom of the sliding table, and a sliding groove for the sliding fit of the first convex frame is formed between adjacent guiding protrusions. Pulling rings for connecting the traction mechanism are respectively arranged at both ends of the sliding table; the grain storage warehouse shelf is composed of multiple unit storage bins stacked and arranged; the traction mechanism includes a traction motor that slides up and down, and a traction rope for connecting the pulling ring is fixed to the output end of the traction motor; a first driving motor for controlling the lifting of the traction motor by a steel wire rope is installed at the bottom of the movable support frame. This invention can reduce grain loss, accurately and quickly complete the out and in of grains, reduce the operation of transferring grains between warehouses, and reduce the grain storage cost.

[0005] However, in the above-mentioned existing patents, although the problem of grain loss during the storage and transportation process can be solved, since the grains are in contact with the interior of the container, the bulk grains are in direct contact with the inner wall of the container during transportation, and are easily subject to friction, collision and extrusion, resulting in particle breakage and quality degradation. Moreover, the temperature and humidity fluctuations inside the container directly affect the grain quality. In a high-temperature and high-humidity environment, the grains are easily hygroscopic and dew condensation occurs, leading to mildew; in a low-temperature environment, the grains may be damaged due to frosting. Summary of the Invention

[0006] The purpose of the present application is to provide a polymer air film bladder-type container grain storage device and a grain storage method, which are used to solve the problem that the grains are in direct contact with the inner wall of the container during the existing container grain storage process.

[0007] The present invention can make full use of the temporary storage of grains in large grain depots and railway freight yards and the continuous national transfer, relieve the national policy-based grain purchase and storage demand, facilitate the sale of grains by grain-growing farmers, facilitate the grain depot to purchase grains when the warehouse capacity is insufficient, reduce the national warehouse construction pressure, and save costs to a certain extent compared with building warehouses for grain storage of the same quantity.

[0008] In order to achieve the above purpose, the present invention adopts the following technical solutions: A polymer air film bladder-type container grain storage device includes an air film storage body. A plurality of fixing ropes are fixedly connected to the top and the bottom around the air film storage body. An outer container body is arranged outside the air film storage body. Penetration holes are provided at the positions corresponding to the fixing ropes at the top and around the container body. The fixing ropes sequentially pass through the corresponding penetration holes. The fixing ropes and the penetration holes are used to fix the air film storage body inside the container body. The fixing of the container body and the air film storage body by the fixing ropes can prevent the air film storage body from moving during the grain storage process. Due to the mutual action of the forces around, the air film storage body arranged inside the container body can be fixed, and the mutual acting forces can also prevent the air film storage body from generating wrinkles inside the container body. The mutual acting forces of the fixing ropes around can effectively offset the bumps, vibrations and inertial forces during transportation, and avoid the air film storage body from sliding or toppling inside the container body.

[0009] As a further improvement of the present invention, a multi-functional grain inlet / outlet and a multi-functional grain inlet and exhaust port are provided at the top of the air film storage body. A multi-functional grain outlet and exhaust port is provided on the side of the air film storage body close to the opening of the container body. A first fixed support rod is fixedly connected to the top of the container body. A plurality of rotating tubes are symmetrically and rotatably connected to the outside of the first fixed support rod. At the top of the rotating tubes, a first series connection plate and a second series connection plate are symmetrically and fixedly connected along the direction of the first fixed support rod respectively. On both sides of the container body away from the opening of the container body, second fixed support rods are symmetrically and fixedly connected. The outside of the second fixed support rods is also rotatably connected with rotating tubes. At the ends of the rotating tubes away from each other, a second series connection plate is also fixedly connected. Hook members are fixedly connected to the first series connection plate and the second series connection plate at positions corresponding to the first fixed rope respectively. By the rotation between the rotating tube and the first fixed support rod, the first fixed rope can be tightly clamped outside the container body. The uniform fixing force can inhibit the permanent deformation of the air film storage body caused by long-term uneven stress, and extend the service life. Moreover, the stable fixing method can reduce the friction or collision between the air film storage body and the inner wall of the container body, and avoid scratching, puncturing or tearing caused by shaking.

[0010] As a further improvement of the present invention, a plurality of ventilation openings are symmetrically and fixedly connected to both sides of the container body in the direction where the second fixed support rods are located. Threaded rings are fixedly connected to the top of the container body at the multi-functional grain inlet / outlet and the multi-functional grain inlet and exhaust port. Rotating grooves are provided at the centers of the ventilation openings close to the inside of the container body, and the rotating grooves are also provided on the inner wall of the container body. Four sliding door panels are fitted and movably connected to the opening of the container body. A remote grain condition information terminal is provided on the side of the second sliding door panel from top to bottom away from the inside of the container body, and a protection frame is fixedly connected to the side of the second sliding door panel from top to bottom away from the inside of the container body. Thus, the effect of detecting the situation of the air film storage body inside the container body can be achieved. The remote grain condition information terminal replaces manual inspection, reduces labor costs, and has obvious advantages especially during bad weather or night inspections. Moreover, through real-time data warning, measures can be taken in time to prevent mildew and pests, and reduce grain losses.

[0011] As a further improvement of the present invention, a rotating motor is fixedly connected to the side of the protective frame away from the container body, and a meshing wheel 1 is fixedly connected to the output end of the rotating motor, and a conical wheel 1 is fixedly connected to the end of the meshing wheel 1 away from the rotating motor, and a conical wheel 2 is meshed on the side of the conical wheel 1 away from the meshing wheel 1, and a meshing wheel 2 is fixedly connected to the side of the conical wheel 2 close to the inner wall of the container body, and a rotating block is rotatably connected to the side of the meshing wheel 2 away from the conical wheel 2, and a plurality of meshing wheels 2 and rotating blocks are provided, and a plurality of the rotating blocks are rotatably connected to the inside of the rotating groove, and a meshing chain is meshed on the outside of the meshing wheel 2, and an exhaust fan is fixedly connected to the end of the meshing wheel 2 away from the rotating block at the corresponding position of the vent. Through the contact between the conical wheel 1 and the conical wheel 2, when the container body is in a closed state, the exhaust fan can be used to ventilate the air film storage body. During the storage process, the grain in the air film storage will generate heat due to respiration, which will cause the temperature inside the grain pile to rise, which may cause the growth of mold and insect pests. The heat dissipation mechanism rotating through the meshing chain will accelerate the air flow, take away the heat inside the grain pile, lower the temperature, and effectively inhibit the growth of mold and insect pests. The high temperature and closed environment will accelerate the aging of the material of the air film storage body and reduce its service life. By reducing the internal temperature, the service life of the air film storage body can be effectively extended.

[0012] As a further improvement of the present invention, a bismuth telluride plate is welded to one end of the container body away from the rotating motor, and a wire one is fixedly connected to one end of the bismuth telluride plate close to the rotating motor, and the other end of the wire one is fixedly connected to the surface of the container body. A wire two is fixedly connected to the side of the 102 close to the rotating motor, and one end of the wire two away from the bismuth telluride plate is on the rotating motor. The bismuth telluride plate is made of solid bismuth telluride, and a hot terminal point is formed at the welding point between the bismuth telluride plate and the container body, and a cold terminal point is formed between the bismuth telluride plate and the container body at one end of the wire, and the wire one is used to form a closed circuit between the bismuth telluride plate and the container body. When the external temperature of the container body is too high, the temperature of the welding point between the bismuth telluride plate and the container body will rise, causing a temperature difference between the hot end and the cold end. According to the Seebeck effect, direct current will be generated between the two contacts, and the direct current will be transmitted to the rotating motor through the second conductor, thereby driving the start of the rotating motor. When the external temperature of the container exceeds the temperature difference threshold between the hot end and the cold end, the bismuth telluride plate will immediately generate enough electromotive force to drive the motor, and the heat dissipation device will automatically start, with a response speed much faster than the traditional temperature control system. Moreover, the bismuth telluride plate can generate microcurrent when the temperature difference is ≥10℃, maintain low power consumption standby under small temperature difference, and output efficiently under large temperature difference, which meets the long-term low energy consumption requirements of the container body.

[0013] As a further improvement of the present invention, the air film storage body further includes a surface waterproof layer. On the side close to the inside of the air film storage body, a first PVC glue layer is fixedly connected. On the side of the first PVC glue layer away from the surface waterproof layer, a polyester fiber layer is fixedly connected. On the side of the polyester fiber layer away from the first PVC glue layer, a second PVC glue layer is fixedly connected. On the side of the second PVC glue layer away from the polyester fiber layer, a glue layer is fixedly connected. On the side of the glue layer away from the second PVC glue layer, a PET layer is fixedly connected. On the side of the PET layer away from the glue layer, a metal foil is fixedly connected. On the side of the metal foil away from the PET layer, a PE layer is fixedly connected. The surface waterproof layer is located on the outer side of the air film storage body, and the PE layer is located on the inner wall of the air film storage body. Inside the polyester fiber layer, a polyester fiber mesh is fixedly connected. Injection notches are formed inside the polyester fiber layer and the polyester fiber mesh. Capsaicin can be injected into the polyester fiber mesh through the injection notches, so that it can continue to be used after the capsaicin inside the polyester fiber mesh volatilizes. The design of the injection hole slots allows capsaicin to be directly replenished during the use of the air film storage body without disassembling or replacing materials, reducing the maintenance difficulty and cost. The replenishment process can be operated locally without affecting the overall airtightness and structural integrity of the air film storage. Moreover, by using the method of physical capsaicin stimulation to drive away mice, the dependence on chemical agents can be reduced, thereby reducing the potential harm to the environment and operators.

[0014] As a further improvement of the present invention, threaded tubes are internally threaded in the threaded rings. On one side of each threaded tube, a multi-functional airtight cover is fixedly connected. On the side of the threaded tube away from the multi-functional airtight cover, a functional tube is provided. On the side of the functional tube away from the threaded tube, a rotating ring is rotatably connected. At the center of the inside of the multi-functional airtight cover, four air injection and exhaust pipes are fixedly connected. A connecting tube is fixedly connected to the middle parts of the two farthest functional tubes. A corrugated tube is arranged outside the connecting tube close to the top functional tube. Electric control valves are arranged at the positions where the connecting tubes are close to the functional tubes. The air injection and exhaust pipes are inserted into the inside of the rotating ring. There is no connection relationship between the functional tubes and the threaded tubes. The three rotating rings are respectively rotatably connected inside the multi-functional grain inlet and outlet, the multi-functional grain inlet and air exhaust port, and the multi-functional grain outlet and air exhaust port. The electric control valves form a closed-loop circuit, so that the grain controlled atmosphere circulation inside the air film storage body is uniform. Compared with the traditional ventilation method, the small centrifugal fan has lower energy consumption and higher ventilation efficiency, reducing energy waste. Moreover, when there are pests in the grain, carbon dioxide can be filled through the multi-functional grain outlet and air exhaust port. By utilizing the sensitivity of pests to high-concentration carbon dioxide, pollution-free pest control can be achieved, avoiding chemical agent residues and ensuring grain safety. By connecting with the multi-functional port at the top of the air film storage body, the circulation of the gas inside the air film storage body can also be realized, evenly distributing the temperature, humidity and gas components of the grain pile, and preventing grain spoilage caused by local temperature difference or excessive humidity.

[0015] A method for storing grain in a polymer gas film bladder container, specifically comprising: S1, preparation stage: prepare the container body and the air film storage body; S2, installation stage: fix the air film storage body and seal it; S3, grain storage stage: loading grain and closing the grain inlet and outlet; S4, monitoring stage: ventilation, cooling and grain condition monitoring; S5, quality control stage: pest control and quality tracking.

[0016] As a further improvement of the present invention, in step S2, the fixed air film storage body is fixed by a fixed rope and a hook, and the fixing of the fixed rope and the hook is used to ensure that the air film storage body and the container body are integrated, and a 1-meter-long arc-shaped airtight zipper is reserved at the bottom of the air film storage body to drain the residual food when the food is discharged, and the main material of the air film storage body is a PE+PET foil multilayer structure high-strength waterproof airtight film, and the polyester fiber layer and the polyester fiber mesh are injected with 1.6% capsaicin through the injection notch. The 1.6% capsaicin solution injected into the polyester fiber layer and the polyester fiber mesh can effectively inhibit mold and pests, thereby ensuring food safety.

[0017] As a further improvement of the present invention, the connecting pipe and all the electric control valves are arranged on the top of the air film storage body and connected to the pipeline on the sliding door plate to form a closed loop. The connecting pipe and the electric control valve are used to make the grain gas conditioning circulation in the air film storage body uniform. The exterior of the container body adopts nano anti-radiation polymer coating, which is used to block the mid-infrared rays in the sunlight. The empty space on the inner wall of the container body is sprayed with 2 cm thick rigid foam polyurethane. The closed loop design formed by the connecting pipe, the electric control valve and the pipeline on the top of the air film storage body realizes the uniformity of the grain gas conditioning circulation, thereby improving the efficiency and stability of gas conditioning treatment.

[0018] Compared with the prior art, the present invention has the following beneficial effects: Through the hole slot, fixing rope and hook, the operator passes the fixing rope through the hole slot and hangs the fixing rope on the hook. Since the fixing ropes are arranged at the four corners of the side of the air film hoard body, when all the fixing ropes are hung on the hook, the four-corner fixing design ensures that the various parts of the air film hoard body are balanced in force, avoiding the risk of deformation or damage caused by local stress concentration. The tension of the fixing rope can also tighten the surface of the air film hoard body to prevent wrinkles caused by internal air pressure changes or external extrusion, ensuring the stability of the air film hoard body. In highways, railways or shipping, the interaction force of the air film hoard body can also buffer vibrations, thereby protecting the air film hoard body from impact.

[0019] Through the conical wheel 1, the conical wheel 2 and the meshing chain, after the grain storage inside the air film storage body is completed, the sliding door panel is connected to the sliding of the container body opening, so that when the sliding door panel moves to the top to close the container body opening, the fixed support rod 1 meshes the ventilation opening, and the direct current generated by the Seebeck effect starts the rotating motor, so that the meshing chain is driven to rotate through mutual meshing, thereby achieving the effect of ventilating and cooling the inside of the container body after the grain storage inside the air film storage body is completed. In addition, odor or trace harmful gases may be generated during the grain storage process. The rotating ventilation of the meshing chain can accelerate the gas discharge, ensuring that the internal air is fresh when the sliding door panel is opened after the ventilation is stopped, and protecting the health of personnel. In the early stage of grain storage, frequent ventilation and heat dissipation may be required to reduce the temperature of the grain pile, and the ventilation frequency needs to be reduced in the later stage of grain storage. Through the external controllable ventilation structure, a stable environmental condition will be provided for subsequent grain delivery, inspection or maintenance operations to ensure smooth operation.

[0020] Through the air injection and exhaust pipe, connecting pipe, bellows and electric control valve, a multifunctional airtight cover is arranged on the surface of the sliding door panel. The air film hoard body inside the sliding door panel is provided with a multifunctional airtight cover, which can be used to discharge grain when the cover is opened, and the internal grain can be ventilated and cooled by connecting the air injection and exhaust pipe on the cover to an external small centrifugal fan when the cover is closed. When there are pests in the grain, carbon dioxide can be injected into the pipe to kill the pests and the circulation can be connected to the multifunctional port on the top of the air film hoard body to even out the internal gas concentration. The external small centrifugal fan is connected through a thick pipe to force ventilation of the grain in the air film hoard body, quickly reduce the grain temperature, and prevent the grain from mildew, germination or quality degradation due to high temperature. The multifunctional airtight cover and functional pipe can be installed and adjusted according to actual needs to meet the needs of grain storage of different scales and types.

[0021] Capsaicin can be injected into the polyester mesh through the polyester mesh and the injection slot. During the manufacturing process of the air film storage body, capsaicin is dissolved in the co-solvent in a certain proportion, and then fully integrated with the PVC material of the air film storage body, which plays a role in preventing mice from gnawing and preventing mold. However, during use, capsaicin will inevitably be lost, resulting in poor effect. Capsaicin can be re-injected into the air film storage body through the injection slot. Capsaicin is naturally irritating to mice. After injection, it can form a continuous chemical barrier to reduce the risk of mice gnawing. Regularly replenishing capsaicin can ensure the protective effect and avoid protection failure due to loss. In addition, the active ingredients in capsaicin have antibacterial effects, which can inhibit the growth of mold and extend the food storage period.

[0022] Through the remote grain condition information terminal, the remote grain condition information terminal collects the inspection data of the temperature, humidity and gas composition detectors of the grain inside the air film storage bin body automatically, and transmits various grain condition information, the filled quantity, quality information and the positioning of the container body of the container to a mobile phone or a computer through an external antenna connected by the information terminal, so as to realize the traceability of grain storage information. The system records key information such as the warehousing time, quantity, quality and container positioning of each batch of grain, forms an electronic file, and the management personnel can view the grain condition data at any time through the mobile phone APP or the PC side, which is especially suitable for large grain depots or cross-regional warehousing enterprises.

[0023] Through the container body, bismuth telluride plates, wire one and wire two, compared with traditional mechanical temperature controllers or electronic sensors, the bismuth telluride plates have no aging and wear problems, and the thermoelectric conversion process does not depend on electronic signals, so the stability is greatly improved in the metal structure or strong electromagnetic environment of the granary. Moreover, the bismuth telluride plates are welded to the container body, and wire two is directly connected to the motor, reducing components such as intermediate relays and controllers, and the installation cost will be reduced. The environmental thermal stress is converted into controllable electric energy, providing an intrinsically safe active heat dissipation solution for grain storage. Brief Description of the Drawings

Detailed implementation manner

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment, a polymer air film bladder type container grain storage device and a grain storage method, as Figure 13 shown, including the following steps: S1, Preparation stage: Prepare the container body 101 and the air film bin body 201.

[0042] During the manufacturing process of the air film bin body 201, the air film bin body 201 includes a surface waterproof layer 301. The surface waterproof layer 301 is fixedly connected to a first PVC glue layer 302 on the side close to the inside of the air film bin body 201. The side of the first PVC glue layer 302 away from the surface waterproof layer 301 is fixedly connected to a polyester fiber layer 303. The side of the polyester fiber layer 303 away from the first PVC glue layer 302 is fixedly connected to a second PVC glue layer 304. The side of the second PVC glue layer 304 away from the polyester fiber layer 303 is fixedly connected to a glue layer 305. The side of the glue layer 305 away from the second PVC glue layer 304 is fixedly connected to a PET layer 306. The side of the PET layer 306 away from the glue layer 305 is fixedly connected to a metal foil 307. The side of the metal foil 307 away from the PET layer 306 is fixedly connected to a PE layer 308. The surface waterproof layer 301 is located on the outside of the air film bin body 201, and the PE layer 308 is located on the inner wall of the air film bin body 201. A polyester fiber mesh 309 is fixedly connected inside the polyester fiber layer 303. Injection slots 310 are formed inside the polyester fiber layer 303 and the polyester fiber mesh 309. During the manufacturing process of the air film bin body 201, the layers from the surface waterproof layer 301 to the PE layer 308 are sequentially adhered. Capsaicin can play a role in preventing rats from gnawing and mildew prevention. During use, capsaicin will inevitably be consumed, resulting in poor effects. Through the injection slots 310, capsaicin can be re-injected into the air film bin body 201. Capsaicin has a natural irritant effect on rats. After injection, a continuous chemical barrier can be formed to reduce the risk of rat gnawing. Regularly replenishing capsaicin can ensure the protection effect and avoid the failure of protection caused by consumption.

[0043] S2, Installation stage: Fix the air film bin body 201 and perform sealing treatment.

[0044] The fixed air film storage body 201 is clamped by a fixed rope 202 and a hook 209. The clamping of the fixed rope 202 and the hook 209 is used to ensure that the air film storage body 201 and the container body 101 become an integrated unit. A 1-meter-long arc-shaped airtight zipper is reserved at the bottom of the air film storage body 201 for draining the remaining grain during grain discharging. The main material of the air film storage body 201 is a multi-layer structure high-strength waterproof and airtight film of PE+PET foil. The polyester fiber layer 303 and the polyester fiber mesh 309 are injected with capsaicin at a ratio of 1.6% through the injection notch 310. A number of fixed ropes 202 are fixedly connected to the top and the bottom of the periphery of the air film storage body 201. An external container body 101 is arranged outside the air film storage body 201. Penetration holes 102 are opened at the positions corresponding to the fixed ropes 202 at the top and the periphery of the container body 101. The fixed ropes 202 are sequentially passed through the corresponding penetration holes 102. The fixed ropes 202 and the penetration holes 102 are used to fix the air film storage body 201 inside the container body 101. A multi-functional grain inlet / outlet 203 and a multi-functional grain inlet and exhaust port 204 are opened at the top of the air film storage body 201. A multi-functional grain outlet and exhaust port 205 is opened at the side of the air film storage body 201 close to the opening of the container body 101. A fixed support rod 103 is fixedly connected to the top of the container body 101. A number of rotating tubes 206 are symmetrically rotatably connected to the outside of the fixed support rod 103. At the top of the rotating tubes 206, a series connection plate 207 and a series connection plate 208 are symmetrically fixedly connected along the direction of the fixed support rod 103 respectively. Fixed support rods 105 are symmetrically fixedly connected to the two sides of the container body 101 far from the opening direction of the container body 101. The outside of the fixed support rods 105 is also rotatably connected with rotating tubes 206. At the ends of the rotating tubes 206 far from each other, series connection plates 208 are also fixedly connected. Hooks 209 are fixedly connected to the series connection plate 207 and the series connection plate 208 at the positions corresponding to the fixed ropes 202 one by one. The suspension of the fixed rope 202 and the hook 209 can fix the air film storage body 201 arranged inside the container body 101. The interaction force can also prevent the air film storage body 201 from generating wrinkles inside the container body 101. The interaction forces of the fixed ropes 202 around can effectively offset the bumps, vibrations and inertial forces during transportation, and avoid the air film storage body 201 from sliding or toppling inside the container body 101.

[0045] S3, Grain storage stage: Loading grain and closing the grain inlet / outlet. Closing the grain outlet will cause the first conical wheel 113 and the second conical wheel 114 to engage.
