[0042] In the technical scheme adopted in this embodiment, the bin body 100 is the basic structure of the grain bin circulating ventilation device and is used for storing grain. The bin body 100 is provided with mounting holes penetrating in and out, which provide a channel for installation of the circulating pipeline 400. The pre-embedded component is a component pre-installed in the wall during construction of the bin body 100 to facilitate installation and fixation of the circulating pipeline 400. The circulating pipeline 400 is a key component of the grain storage circulation and can enable the gas in the grain pile to circulate. The circulating pipeline 400 generally has a wall-penetrating portion penetrating through the pre-embedded pipe 200 and a fixed portion fixed on the pre-embedded plate 300. By means of the first deviation correction component 500, the size and position deviation between the wall-penetrating portion of the circulating pipeline 400 and the pre-embedded plate 300 can be corrected when the circulating pipeline 400 needs to be installed, and by means of the second deviation correction component 600, the size and position deviation between the fixed portion of the circulating pipeline 400 and the pre-embedded plate 300 can be corrected. After the deviation correction is completed, the first deviation correction component 500 and the second deviation correction component 600 are both welded and fixed with the circulating pipeline 400. Through cooperation of the first deviation correction component 500 and the second deviation correction component 600, the size and position deviation of the pre-embedded pipe 200 and the pre-embedded plate 300 can be corrected, the circulating pipeline 400 can be installed adaptively, the connection between the circulating pipeline 400 and the bin body 100 can be ensured to be stable, the deviation of the circulating pipeline 400 caused by installation errors or external forces can be reduced, and thus the normal operation and effect of the circulating system can be ensured.

[0043] Specifically, the grain bin circulating ventilation device comprises a bin body 100, a circulating pipeline 400, and a deviation correction and fixation assembly.

[0044] The bin body 100 is generally composed of an inner wall and an outer wall and has a certain bearing capacity, which can support the weight of grain and any pressure that may be generated during storage. The bin body 100 is provided with mounting holes penetrating in and out, which can be used to install the circulating pipeline 400.

[0045] The pre-embedded component is embedded in the wall to facilitate installation of the circulating pipeline 400. The pre-embedded component generally comprises a pre-embedded pipe 200 and a pre-embedded plate 300. The pre-embedded pipe 200 simplifies the installation process of the circulating pipeline 400 and facilitates the circulating pipeline 400 to pass through the wall of the bin body 100 and communicate with the inside. The pre-embedded plate 300 is used to fix the circulating pipeline 400 at the outer wall portion. It can be understood that due to the civil pre-embedding process, there is generally a certain gap between the pre-embedded pipe 200 and the pre-embedded plate 300 and the design size and position size in the actual project construction, which causes the circulating pipeline 400 to need to take deviation correction measures for installation. There may be size and position deviation in the left-right direction, the front-rear direction, and the up-down direction. To adapt to the installation of the circulating pipeline 400, the deviation needs to be compensated. In this embodiment, the pre-embedded pipe 200 is used in single set, and the pre-embedded installation plate is used in pairs and is arranged in multiple pairs along the up-down direction

It can be understood that the embedded pipe 200, the adjusting ring pipe 510 and the movable inner pipe 520 are corrected to be in good installation positions, and then are welded and fixed, so as to ensure the air tightness of the loop pipe 400 and improve the structural strength and service life of the loop pipe 400.
