Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen regulating components, in particular to a gas regulating component for filling nitrogen in a granary. Background Art

[0002] In the field of grain storage in granaries, nitrogen gas storage technology has been widely used to ensure the safe storage of grain and prevent pests, mildew and quality degradation. This technology creates a low-oxygen environment by filling the granary with high-purity nitrogen, effectively inhibiting the growth of pests, the reproduction of microorganisms and the respiration of grain itself, thereby extending the storage period of grain and maintaining its quality. However, in the existing nitrogen gas storage system, the gas control component is a key component, and its performance and degree of automation directly affect the grain storage effect and ease of operation.

[0003] At present, the common gas control components on the market are mainly valves, which cooperate with the pipeline system to control the charging and release of nitrogen. However, most of these valves are manually operated and have the following shortcomings:

[0004] 1. Difficult to adjust automatically: Manual valves need to be opened and closed manually, and cannot be adjusted automatically and accurately in real time according to parameters such as oxygen concentration and nitrogen concentration in the granary. This makes it difficult to maintain a constant nitrogen concentration during the nitrogen filling process, affecting the grain storage effect.

[0005] 2. Low efficiency: Manual operation is not only time-consuming and labor-intensive, but also has obvious limitations when operating in large granaries or multiple granaries at the same time, making it difficult to meet the needs of efficient and rapid gas regulation.

[0006] 3. Safety hazards: Manual valves may be at risk of negligence or misoperation during operation, such as nitrogen leakage, low oxygen concentration leading to oxygen deficiency for operators and other safety issues. Utility Model Content

[0007] (I) Purpose of the utility model

[0008] In view of this, the purpose of the present invention is to provide a gas regulating component for filling a granary with nitrogen, which solves the problems raised in the above background.

[0009] (II) Technical solution

[0010] A gas control component for filling a granary with nitrogen comprises a nitrogen generator, one end of the nitrogen generator is connected to a first connecting pipe, one end of the first connecting pipe is connected to a flow tube, a gas flow meter is arranged on the outer surface of the flow tube, one end of the gas flow meter is connected to a second connecting pipe, one end of the second connecting pipe is connected to a regulating pipe, a first electronic valve is arranged on the outer surface of the regulating pipe, and one end of the regulating pipe is connected to a delivery pipe.

[0011] Preferably, a spare pipe is connected between the second connecting pipe and the delivery pipe, and a manual valve is provided on the outer surface of the spare pipe.

[0012] Preferably, an electronic pressure gauge is provided on the outer surface of the first connecting pipe.

[0013] Preferably, a pressure relief pipe is connected to one side of the second connecting pipe, and a second electronic valve is provided on the outer surface of the pressure relief pipe.

[0014] Preferably, a fixing ring is fixedly mounted on the outer surfaces of the delivery pipe, the second connecting pipe and the first connecting pipe, and a fixing rod is connected to one side of the fixing ring, and the fixing rod is fixedly connected to the outer surface of the nitrogen generator.

[0015] Preferably, the first connecting pipe, the flow pipe, the second connecting pipe, the regulating pipe and the delivery pipe are connected via a flange.

[0016] Preferably, the pressure relief pipe is connected to the storage tank through a ferrule with other pipelines.

[0017] It can be seen from the above technical solutions that the present application has the following beneficial effects:

[0018] 1. The utility model reduces the need for manual intervention and improves operating efficiency through automatic adjustment. Operators do not need to frequently adjust valves manually and can focus on other more important tasks. At the same time, precise control also reduces nitrogen waste caused by flow fluctuations and improves overall operating efficiency.

[0019] 2. The utility model can monitor the flow and concentration of nitrogen in real time through an automated control system. Once an abnormal situation is found (such as nitrogen leakage, low oxygen concentration, etc.), measures can be taken quickly to make adjustments, thereby reducing safety hazards caused by human negligence or misoperation. The high-precision gas flow meter and the first electronic valve reduce safety risks caused by equipment failure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, and use. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0027] See also Figure 1-5 , an embodiment provided by the utility model:

[0028] A gas control component for filling a granary with nitrogen includes a nitrogen generator 1, one end of the nitrogen generator 1 is connected to a first connecting pipe 2, one end of the first connecting pipe 2 is connected to a flow tube 3, a gas flow meter 4 is arranged on the outer surface of the flow tube 3, one end of the gas flow meter 4 is connected to a second connecting pipe 5, one end of the second connecting pipe 5 is connected to a regulating pipe 6, a first electronic valve 7 is arranged on the outer surface of the regulating pipe 6, and one end of the regulating pipe 6 is connected to a delivery pipe 8. An electronic barometer 211 is arranged on the outer surface of the first connecting pipe 2, and the electronic barometer 211 can monitor the nitrogen pressure output by the nitrogen generator 1 in real time to ensure that the nitrogen maintains a stable pressure state during the delivery process.

[0029] A spare pipe 9 is connected between the second connecting pipe 5 and the delivery pipe 8, and a manual valve 911 is provided on the outer surface of the spare pipe 9. As an additional delivery path, the spare pipe 9 can be quickly switched to use when the main delivery path fails or needs maintenance, ensuring that nitrogen can be continuously and stably supplied to the granary, avoiding gas supply interruption caused by a single path failure. In an emergency, such as when the main delivery path is suddenly blocked, leaked or damaged, the operator can quickly open the manual valve 911 on the spare pipe 9 and enable the spare path, thereby quickly restoring the nitrogen supply and reducing the risk of grain storage caused by failure. A pressure relief pipe 811 is connected to one side of the second connecting pipe 5, and a second electronic valve 812 is provided on the outer surface of the pressure relief pipe 811. During the nitrogen delivery process, if the internal pressure of the system rises abnormally and exceeds the preset safety range, the second electronic valve 812 will automatically open and release the excess pressure into the storage tank through the pressure relief pipe 811 to protect the system equipment and pipelines from damage. The pressure relief pipe 811 is connected to the storage tank through a ferrule and other pipelines. The pressure relief pipe 811 is connected to the storage tank and other pipelines through a ferrule, which not only ensures the unobstructed flow of the pressure relief pipeline, but also avoids leakage problems caused by improper connection.

[0030] The outer surfaces of the delivery pipe 8, the second connecting pipe 5 and the first connecting pipe 2 are all fixedly installed with a fixing ring 712, and one side of the fixing ring 712 is connected to a fixing rod 711, and the fixing rod 711 is fixedly connected to the outer surface of the nitrogen generator 1. The delivery pipe 8, the second connecting pipe 5 and the first connecting pipe 2 are firmly fixed to the nitrogen generator 1 through the fixing ring 712 and the fixing rod 711, which prevents the pipeline from loosening or falling off due to vibration, external force and other factors. The first connecting pipe 2, the flow pipe 3, the second connecting pipe 5, the regulating pipe 6 and the delivery pipe 8 are connected by a flange 111. The flange 111 is firmly connected, has good sealing performance, and is easy to disassemble and install. The first connecting pipe 2, the flow pipe 3, the second connecting pipe 5, the regulating pipe 6 and the delivery pipe 8 are tightly connected together through the flange 111, ensuring the integrity and sealing of the entire gas control assembly.

[0031] Working principle: The nitrogen generator 1 is the core component of the whole system, which is responsible for separating oxygen and other impurities in the air and purifying high-purity nitrogen. The nitrogen enters the flow tube 3 through the first connecting pipe 2. In the flow tube 3, the flow of nitrogen is monitored in real time by the gas flow meter 4. The gas flow meter 4 adopts a high-precision sensor, which can accurately measure the instantaneous flow and cumulative flow of nitrogen to ensure that the supply of nitrogen matches the actual demand of the granary. After flow monitoring, the nitrogen enters the regulating pipe 6 through the second connecting pipe 5. A first electronic valve 7 is installed on the regulating pipe 6, which can automatically adjust according to the preset nitrogen concentration or flow parameter. When the nitrogen flow monitored by the gas flow meter 4 deviates from the set value, the first electronic valve 7 will automatically adjust the opening, increase or decrease the supply of nitrogen to maintain the stability of the nitrogen flow, and the adjusted nitrogen is safely transported to the inside of the granary through the conveying pipe 8.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
