Description

Technical Field

[0001] The utility model relates to the technical field of insecticide and sterilization, in particular to an oxygen reduction and nitrogen filling insecticide device for storehouse sealing. Background Art

[0002] Archives and cultural relics are easily destroyed by insects and microorganisms when stored for a long time. The commonly used insecticidal and antibacterial method is nitrogen filling and oxygen reduction technology. Nitrogen is used to kill insects in archives and books, which is essentially nitrogen filling and oxygen reduction. Since oxygen is an indispensable prerequisite for the survival of all organisms, when the oxygen content is lower than a certain concentration, the physiological activities of pests to maintain life cannot proceed normally, the decomposition of substances in the body, metabolic activities and enzyme activities are severely damaged, and the physiological activities to maintain life are stopped, causing the pests to suffocate and die due to lack of oxygen.

[0003] The publication number of the existing public technology is: CN210671826U. A pest control and storage maintenance gas regulating device includes an air compressor, an air purification device, a nitrogen oxide generator, a flow controller, an insecticide chamber and an oxygen control PLC. The air compressor, the air purification device and the nitrogen oxide generator are connected in sequence through pipelines. The nitrogen oxide generator includes a first air outlet and a second air outlet. A first oxygen concentration sensor is installed at the first air outlet. The second air outlet is connected to the air inlet of the flow controller. The air outlet of the flow controller is connected to the air inlet of the insecticide chamber. A second oxygen concentration sensor is installed in the insecticide chamber. The oxygen control PLC is electrically connected to the first oxygen concentration sensor, the flow controller and the second oxygen concentration sensor. The utility model regulating device can realize stepless regulation of oxygen concentration in the insecticide chamber, the concentration gradient during nitrogen filling and replacement is not large, and real-time monitoring can be performed to quickly reduce the oxygen concentration in the insecticide chamber to a set value, the replacement time is short, the replacement efficiency is high, and CN214087728U is a nitrogen generator, including a nitrogen generator, the four corners of the bottom end of the nitrogen generator are fixedly installed with moving mechanisms, the four moving mechanisms all include fixed round blocks, the four fixed round blocks are respectively fixedly installed at the four corners of the bottom end of the nitrogen generator, and the four fixed round blocks are equipped with rotating devices adapted for rotation. The bottom centers of the four rotating circular blocks are vertically fixedly connected with support rods, the bottom ends of the four support rods respectively penetrate the corresponding bottoms of the fixed circular blocks and are fixedly installed with rollers, two extrusion positioning mechanisms are fixedly installed at the bottom of the nitrogen generator, the two extrusion positioning mechanisms both include drive boxes, the two drive boxes are fixedly installed in parallel at the bottom of the nitrogen generator, worm wheels are rotatably installed at the bottoms of the inner cavities of the two drive boxes, and one side of the two worm wheels is meshed with a worm. The utility model provides a nitrogen generator, which has the advantage that it is not easy to slide at multiple angles in the horizontal direction when the nitrogen generator is working.

[0004] Combining the above patents and the existing situation, it is not difficult to find that a nitrogen generator is used when reducing oxygen and filling nitrogen to kill insects in a warehouse, and the existing nitrogen generator is often fixed in a specific position and connected to the warehouse through a pipeline, which greatly reduces the overall flexibility of the device, and the setting of the pipeline will also increase the overall use cost, which is not convenient for the use of micro-sized warehouses, and the increase in the number of warehouses will require the increase of corresponding equipment. The overall use effect is not very ideal, and the nitrogen generator is mostly directly exposed to the outside when idle, resulting in a significant increase in the probability of damage, which is not conducive to long-term use and lacks protection measures. At the same time, the nitrogen generator is prone to vibration during operation, and the vibration will cause the universal wheel at the bottom to move, thereby affecting the overall operation stability, and the use effect is not very good.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
