Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain storage engineering technology, and more specifically, to a modified atmosphere device embedded in the wall of a grain warehouse. Background Technology
[0002] The existing circulating controlled atmosphere system mainly consists of four parts: a nitrogen generator, a circulation system, a nitrogen concentration detection device, and an automatic control device. Before nitrogen filling, the airtightness of the storage room must be tested, primarily using a mobile airtightness detection device. Nitrogen generation can be centralized outside the storage room, utilizing the bottom ventilation ducts and circulation ducts to form a closed loop, allowing nitrogen to circulate under the drive of the circulation fan, promoting uniform distribution of nitrogen in the grain pile to achieve insecticidal and bacteriostatic effects. Nitrogen detection is mainly done manually on-site, and the circulation fan is activated in real time based on the test results. The disadvantages of the existing technology are: 1. The airtightness of the storage room before controlled atmosphere filling is not guaranteed. 1. Air tightness testing requires multiple personnel to install mobile testing devices on-site, which is labor-intensive, resource-intensive, and inefficient, and sometimes results in testing not being conducted according to regulations. 2. After on-site air tightness testing, the ventilation openings must be resealed. 3. The timing of starting the circulating fan is too subjective, lacking objective reference. 4. There is a lack of real-time monitoring and analysis of testing data and pests throughout the entire controlled atmosphere period. 5. The functions of the circulating controlled atmosphere system are relatively limited. 6. There is a lack of technical support from expert decision-making systems. Currently, there are only two methods for installing circulating controlled atmosphere pipes: one is installation on the external wall with an insulation layer; the other is installation inside the silo using a dense support system. Both methods have drawbacks. The drawbacks of external installation are: 1. Too many external pipes, affecting aesthetics; 2. Higher cost. The drawbacks of internal installation are: 1. The downward pulling force of the grain pile when removing grain from the silo is extremely large, often causing the pipes to crack or collapse, leading to air leaks; 2. The support system is prone to grain snagging, requiring frequent cleaning of the silo when removing grain from shallow round silos, posing a safety hazard.
[0003] Therefore, there is an urgent need for a modified atmosphere device embedded in the wall of a grain silo to solve the above problems. Utility Model Content
[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of this utility model provide an embedded controlled atmosphere device for grain silos. This device comprises a circulating controlled atmosphere pipe, a gas sampling sleeve, and a nitrogen concentration detection hose. The circulating controlled atmosphere pipe and the gas sampling sleeve are simultaneously embedded into the grain silo wall during slipforming. This invention solves the problem of grain snagging on pipe supports inside the silo, avoiding safety hazards associated with cleaning the silo. Utilizing the wall as insulation material solves the problem of condensation on the pipes. The circulating controlled atmosphere pipe interface within the wall is more secure, preventing leaks and improving airtightness. Simultaneously, it enables intelligent data acquisition and achieves intelligent control, thus addressing the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a grain silo wall-embedded controlled atmosphere device, comprising a grain silo body, a ventilation trench with a ventilation opening at the bottom of the grain silo body, a valve cabinet connected to the ventilation trench with a valve cabinet on one side of the ventilation opening, a circulating fan at the top of the valve cabinet, a circulating controlled atmosphere pipe at the top of the circulating fan, a gas sampling sleeve inside the grain silo body, multiple nitrogen concentration detection hoses inside the gas sampling sleeve, and an intelligent control cabinet at the bottom inside the grain silo body. The circulating controlled atmosphere pipe and the gas sampling sleeve are simultaneously embedded into the grain silo body wall during slipforming.
[0006] In a preferred embodiment, the intelligent control cabinet connection terminal is connected to a host computer, the host computer connection terminal is connected to a PC, and the host computer connection terminal is connected to a mobile phone.
[0007] In a preferred embodiment, the output end of the nitrogen concentration detection hose is connected to the input end of the intelligent control cabinet.
[0008] In a preferred embodiment, the circulating fan is connected to a circulating air conditioning pipe embedded inside the silo wall via a pipe.
[0009] The technical effects and advantages of this utility model are as follows: This invention features a circulating gas control pipe, a gas sampling sleeve, and a nitrogen concentration detection hose. The circulating gas control pipe and the gas sampling sleeve are simultaneously embedded into the grain silo wall during slipforming. This solves the problem of grain snagging on pipe supports in previous silos, avoiding safety hazards during cleaning. Utilizing the wall as insulation material solves the condensation problem on the pipes. The circulating gas control pipe interface within the wall is more secure, preventing leaks and improving airtightness. Simultaneously, it enables intelligent data acquisition and achieves intelligent control. Attached Figure Description
