Description

Technical Field

[0001] This utility model relates to the field of grain storage technology, specifically to an oxygen-deficient storage device for grain storage warehouses. Background Technology

[0002] Currently, grain in major grain-producing areas is primarily stored on the ground. In non-major grain-producing areas, county-level grain storage facilities mostly use storage facilities that were initially modified years ago, which present the following problems: 1. Frequent occurrences of dampness, insect infestations, and rodent damage result in significant grain storage losses; 2. Newly built ground-level grain storage facilities, including all ground-level metal-plate vertical grain warehouses, experience accelerated grain aging under prolonged high temperatures in summer, correspondingly shortening the rotation cycle and effectively increasing storage costs; high temperatures also accelerate the oxidation of fats in grains into fatty acids, thus speeding up grain aging. Third, ground ventilation is costly, and the open bottom of the ground ventilation cage makes it difficult to control the ventilation volume. If grain at the bottom supports the ground ventilation cage, the ventilation volume will be inconsistent with other areas, resulting in uneven ventilation and easy condensation in some areas. Fourth, in the early stages of grain storage, farmers and large-scale grain storage households in major grain-producing areas often experience localized high temperature and humidity during the post-ripening period of grain piles due to uneven residual dryness of the grain. They adopt unscientific ventilation, cooling, and dehumidification methods, causing some grain to mold and deteriorate. Fifth, the method of storing grain using aluminum phosphide fumigation, which has been phased out abroad, is still widely used. Therefore, this utility model proposes an oxygen-deficient storage device for grain storage warehouses to solve the problems mentioned above. Utility Model Content

[0003] The purpose of this utility model is to provide an oxygen-deficient storage device for grain storage warehouses, so as to solve the problems of grain dampness, mold, and insect infestation in current ground grain storage warehouses mentioned in the background art. To achieve the above purpose, this utility model provides the following technical solution: an oxygen-deficient storage device for grain storage warehouses, including a warehouse body, an air inlet main pipe, air inlet branch pipes, and an exhaust main pipe.

[0004] It also includes: the warehouse is equipped with a plastic panel warehouse body with an open top, the upper part of the plastic panel warehouse body is aligned with the lower edge of the window, and a layer of the same plastic panel is fixed on the inner door wall plane, which is on the same plane as the plastic panel. The plastic panel warehouse body is provided with a grain inspection port at the corresponding position of the warehouse door.

[0005] An air intake main is installed on one side of the front of the open plastic silo, penetrating the silo body and the plastic silo body. The air intake main is equipped with several circular, square or semi-circular air intake branch pipes made of metal plates. The air intake branch pipes are sealed bodies, and several small ventilation holes are evenly distributed in the circular part of the sealed air intake branch pipes. A plug is installed at the end of the air intake branch pipes. One end of the air intake main is equipped with an insect screen and a control valve.

[0006] Each window of the warehouse body is equipped with a branch exhaust pipe, which is connected to the main exhaust pipe. One end of the main exhaust pipe is equipped with an insect screen and a control valve.

[0007] Preferably, a plastic film is provided on the top of the open plastic silo body, and the four sides of the plastic film are sealed to the top of the plastic silo body. The sealing connection can be achieved by using adhesive or tape, or by setting a groove structure in the plastic plate and then pressing the plastic cloth into the groove for sealing. This makes the plastic silo body and the plastic film form a sealed whole. A grain sampling tube is provided through the surface of the plastic film, and a sealing cover is provided above the grain sampling tube. An exhaust branch pipe is provided through the plastic film near the window and is connected to the exhaust main pipe outside the window.

[0008] Preferably, a monitoring device is installed above the interior of the warehouse body, and the monitoring device includes a temperature probe, a humidity probe, a grain moisture content detector, an oxygen content detector, a carbon dioxide content detector, a phosphine content detector, a wind speed detector, and an alarm.

[0009] Preferably, the outer wall of the warehouse body is provided with an insulation layer, and the inner wall of the warehouse body is provided with a plastic panel. The contact part between the insulation layer at the top of the warehouse body and the warehouse body is sealed. The windows are sealed with gaskets and the insulation layer is used for insulation. The warehouse door is sealed with gaskets and the insulation layer is used for insulation.

[0010] Preferably, the intake manifold is assembled from several short intake manifolds using quick-release clips.

[0011] The end of the intake manifold is sealed by a quick-release clip.

[0012] Preferably, the diameter of the vent holes on the air intake manifold is not greater than the diameter of the grain particles, and the air intake manifold is wrapped with a layer of metal mesh.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This oxygen-deficient grain storage device first solves the problem of grain dampness caused by various reasons, providing a completely new concept and method for the renovation of old grain storage facilities and the construction of new ones. The availability of both aerobic and oxygen-deficient grain storage devices provides grain storage operators with a choice based on actual conditions.

[0014] Both aerobic and anaerobic storage can extend the storage time of grains, reduce the number of grain rotations and losses, improve the safety of grain storage, and enhance its practicality. The specific details are as follows: The warehouse is equipped with evenly distributed ventilation pipes covering the entire bottom of the warehouse. Carbon dioxide or nitrogen gas is uniformly introduced into the warehouse without any blind spots. The flat surface of the grain pile reduces gas flow deviation during aeration. Air (oxygen) between grain particles is forced or diluted and then discharged from the warehouse through exhaust pipes. Multi-point monitoring devices inside the warehouse are used to control and manage the grain pile during the post-ripening stage. They also provide guidance on temperature and wind speed control for aeration and ventilation in ground-level aerobic grain storage, facilitating the understanding of relevant data on anaerobic or aerobic storage conditions. The double-layer insulation of the plastic sealing panels inside the warehouse and the external insulation layer is highly beneficial for ground, semi-underground, and underground grain storage. This keeps the grain in a sub-low temperature or low temperature, anaerobic or aerobic, semi-dormant or dormant state for extended periods. The lack of oxygen causes the grain's fats to oxidize into lipids. The rate of fatty acid degradation is greatly reduced, extending the shelf life, storage period, and grain rotation time of grains. When storing aerobic grains, it provides excellent moisture protection for the sealing of ground, semi-underground, and underground storage warehouses. Combined with mild aluminum phosphide fumigation, it allows the grains to be stored at sub-low or low temperatures. For grains stored on the ground, in the hot summer, the double-layer insulation of the external insulation layer and the four-sided plastic panels inside the warehouse, combined with multiple ventilations through the air intake pipes during the cool and low-humidity mornings, keeps the grain pile temperature at a possible sub-low temperature.

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.

[0018] Please see Figure 1-8 The present invention provides a technical solution: an oxygen-deficient storage device for grain storage, including a warehouse body 1, an air inlet main pipe 104, an air inlet branch pipe 105, an exhaust main pipe 106, and further including: a plastic plate warehouse body 2 with an open top made of plastic plates installed inside the warehouse body 1, the upper part of the plastic plate warehouse body 2 being aligned with the lower edge of the window 102, a layer of the same plastic plate 112 being fixed to the inner door wall plane of the warehouse door 101, and a grain inspection port 108 being provided on the plastic plate warehouse body 2 at the position corresponding to the warehouse door 101.

[0019] An air intake main duct 104 is installed on one side of the front of the open plastic plate silo 2, penetrating both the warehouse silo 1 and the plastic plate silo 2. The air intake main duct 104 is equipped with several circular, square, or semi-circular air intake branch pipes 105 made of metal plates. Each air intake branch pipe 105 is a sealed body, with several small ventilation holes 1051 evenly distributed in its circular portion. A plug 1052 is installed at the end of each air intake branch pipe 105. One end of the air intake main duct 104 is equipped with an insect-proof net 1042 and a control valve 1041. Each window 102 of the warehouse silo 1 is equipped with an exhaust branch pipe 107, which connects to the exhaust main duct 106. One end of the exhaust main duct 106 is equipped with an insect-proof net 2 1062 and a control valve 2 1061. This design extends grain storage time, reduces grain rotation frequency and losses, improves grain storage safety, and enhances practicality.

[0020] A plastic film 103 is installed on the top of the open plastic silo body. The four sides of the plastic film 103 are sealed to the top of the plastic silo body. The sealing connection can be achieved by using adhesive or tape, or by setting a groove structure in the plastic silo body and then pressing the plastic cloth into the groove for sealing. This makes the plastic silo body 2 and the plastic film 103 form a sealed whole. A grain sampling tube 109 is installed through the surface of the plastic film 103. A sealing cover plate 110 is installed above the grain sampling tube 109. An exhaust branch pipe 107 is installed through the plastic film near the window 102 and is connected to the exhaust main pipe 106 outside the window 102.

[0021] A monitoring device 111 is installed above the interior of warehouse 1. This device includes a temperature probe, a humidity probe, a grain moisture content detector, an oxygen content detector, a carbon dioxide content detector, a phosphine content detector, a wind speed detector, and an alarm. It can monitor the real-time status of the grain. The outer wall of warehouse 1 is covered with an insulation layer 113, and the inner wall is covered with a plastic panel 112. The contact area between the insulation layer 113 at the top of warehouse 1 and the warehouse body 1 is sealed. Window 10... 2. A sealing gasket is used for sealing and an insulation layer 113 is used for insulation. The warehouse door 101 is also sealed with a sealing gasket and an insulation layer 113 is used for insulation, which improves the insulation performance of the warehouse body 1. The air inlet pipe 105 is assembled from several short air inlet pipes 105 by quick-release buckles 1053. The end of the air inlet pipe 105 is connected to a plug 1052 by quick-release buckles 1053. When grain is put into or out of the warehouse, machinery is needed. The air inlet pipe 105 is easy to disassemble and assemble according to the location of the machinery.

[0022] The diameter of the air inlet pipe 105 is smaller than that of the grain particles, and the air inlet pipe 105 is wrapped with a layer of metal mesh 1054 to prevent grain from entering.

[0023] Working principle: Before using this type of oxygen-deficient grain storage device, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, the air inlet pipe 105 with ventilation holes is installed inside the warehouse body 1, completely covering the bottom of the warehouse body 1. Carbon dioxide or nitrogen gas is injected into the bottom of the warehouse body 1 evenly without dead angles through the air inlet pipe 104. The flat surface of the grain pile reduces the phenomenon of gas deviation during the aeration process. The air (oxygen) in the gaps between grain particles is forced or diluted and then discharged outside the warehouse body 1 through the exhaust pipe 107 and the exhaust pipe 106. The multi-point monitoring device 111 installed inside the warehouse body 1 is of great significance for the control and management of the grain pile during the post-ripening period of the grain. It is also of great significance for the control of the aeration of the grain pile and the ventilation, cooling, humidity, wind speed, etc. of the ground-based aerobic storage grain pile, so as to facilitate the timely understanding of relevant indicator data of grain storage in anaerobic or aerobic conditions. The plastic board 112 inside the warehouse body 1 is used for sealing and insulation, and the outside of the warehouse body 1 is used for insulation. The double-layer insulation of the thermal layer 113 is highly beneficial for storing grain on the ground, in semi-underground, and underground. It keeps the grain in a sub-low temperature or low temperature, oxygen-deficient or aerobic, semi-dormant or dormant state for a long time. The lack of oxygen greatly reduces the rate at which the fat in the grain is oxidized into fatty acids, thus extending the shelf life, storage period, and grain rotation time. When storing aerobic grain, the sealing of the semi-underground and underground storage warehouse 1 has a very good moisture-proof effect. Combined with light aluminum phosphide fumigation, the grain is stored in a sub-low temperature or low temperature state. At the same time, for grain stored on the ground, in the hot summer, the double-layer insulation of the thermal layer 113 outside the warehouse 1 and the square plastic panels 112 inside the warehouse 1, combined with the air intake pipe 104, allows for multiple ventilations and cooling in the morning when the temperature is low and the humidity is low, keeping the grain pile temperature in a possible sub-low temperature state.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
