Description

Technical Field

[0001] This utility model relates to the field of grain warehouse ventilation technology, and in particular to a three-dimensional ventilation duct for grain warehouses. Background Technology

[0002] In the construction of modern grain storage silos, mechanical ventilation technology has been widely used to achieve functions such as regulating the temperature of grain inside the silo or implementing circulating fumigation and pest control. Gas is introduced into the bottom of the silo through pipes, and after the gas enters the bottom of the silo, it overflows from bottom to top, thereby expelling the moisture and heat inside the grain.

[0003] Currently, several rows of pipes are laid at the bottom of the grain silo. The pipes have holes so that moisture and heat can be discharged from the bottom up after the grain is piled up. However, the four corners of the grain silo are dead corners, and the pressure on the pipes will increase as the grain piles up inside the silo. This can easily cause the pipes to collapse. Utility Model Content

[0004] In order to solve the problems of the prior art, this utility model provides a three-dimensional ventilation duct for grain storage.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A three-dimensional ventilation duct for grain storage includes a grain storage building body and multiple arc-shaped pipe covers. Arc-shaped bent pipe covers are provided at the four corners of the inner bottom surface of the grain storage building body. Arc-shaped overlapping pieces are fixed to one end of the multiple arc-shaped pipe covers and one end of the multiple arc-shaped bent pipe covers. Overlap grooves are provided on the outer surface of the other end of the multiple arc-shaped pipe covers and the outer surface of the other end of the multiple arc-shaped bent pipe covers. The multiple arc-shaped overlapping pieces are inserted into the overlapping grooves respectively.

[0006] Optionally, multiple arc-shaped pipe covers are arranged equidistantly along the edge line on the bottom surface inside the grain silo building, and the arc-shaped overlapping pieces on the arc-shaped pipe covers and the overlapping grooves on the arc-shaped bent pipe covers are interlocked.

[0007] Optionally, the arc-shaped overlapping piece on the arc-shaped bend tube cover and the overlapping groove on the arc-shaped tube cover are interlocked, and multiple vents extending to the inside are equidistantly opened on the outer surface of the arc-shaped tube cover.

[0008] Optionally, multiple arc-shaped supporting steel bars are fixed at equal intervals on the inner wall of the arc-shaped pipe cover, and pads are fixed at the bottom of the arc-shaped pipe cover near the two side edges.

[0009] Optionally, the inner walls of multiple arc-shaped overlapping pieces are fixed with arc-shaped rubber sheets, and a limiting groove is opened on the inner bottom surface of the overlapping groove.

[0010] Optionally, a limiting strip is fixed to the inner wall of the arc-shaped rubber sheet. The limiting strip is engaged inside the limiting groove. Threaded holes are provided on both sides of the arc-shaped overlapping piece near the bottom edge and on the inner bottom surface of the overlapping groove near the two side edges.

[0011] Optionally, a threaded hole on the arc-shaped overlapping piece extends to the inside of the arc-shaped rubber sheet, and a locking bolt is provided inside the threaded hole.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art. Of course, any product implementing this utility model does not necessarily need to achieve all of the following advantages at the same time: 1. In this utility model, the arc-shaped pipe covers are arranged at equal intervals along the inner bottom edge of the grain silo building body, and are bridged at the corners by arc-shaped bent pipe covers, thereby forming a pipeline for gas flow at the inner bottom edge of the grain silo building body. Furthermore, the arc-shaped supporting steel bars are set on the inner wall of the arc-shaped pipe covers and the pads are fixed at the bottom on both sides of the arc-shaped pipe covers, which can improve the supporting force of the arc-shaped pipe covers and prevent the arc-shaped pipe covers from being crushed by the weight of the grain above.

[0013] 2. In this utility model, when bridging arc-shaped pipe covers with each other and when bridging arc-shaped pipe covers with arc-shaped bent pipe covers, the overlapping and limiting are achieved by interlocking the arc-shaped overlapping piece and the overlapping groove. When the arc-shaped overlapping piece is inserted into the overlapping groove, it can be pre-positioned by interlocking the limiting strip at the bottom of the arc-shaped rubber piece with the limiting groove inside the overlapping groove. Then, the arc-shaped overlapping piece and the overlapping groove are locked and fixed by rotating the locking bolt. Attached Figure Description

Arc-shaped bent pipe covers 8 are provided at the four corners of the inner bottom surface of the grain warehouse building body 13. Arc-shaped overlapping pieces 4 are fixed to one end of the multiple arc-shaped pipe covers 1 and one end of the multiple arc-shaped bent pipe covers 8. Overlapping grooves 6 are provided on the outer surface of the other end of the multiple arc-shaped pipe covers 1 and the other end of the multiple arc-shaped bent pipe covers 8. The multiple arc-shaped overlapping pieces 4 are inserted into the overlapping grooves 6 respectively.

[0019] The effect achieved by the entire embodiment 1 is that the arc-shaped pipe cover 1 is arranged at equal intervals along the inner bottom edge of the grain storage building body 13, and is bridged by the arc-shaped bent pipe cover 8 at the corner, so that a pipeline for gas flow can be formed at the inner bottom edge of the grain storage building body 13. Furthermore, the arc-shaped support steel bar 5 is set on the inner wall of the arc-shaped pipe cover 1 and the pads 3 are fixed at the bottom on both sides of the arc-shaped pipe cover 1, which can improve the support force of the arc-shaped pipe cover 1 and prevent the arc-shaped pipe cover 1 from being crushed by the weight of the grain above.

[0020] Example 2, as Figure 1-5As shown, multiple arc-shaped pipe covers 1 are arranged equidistantly along the edge line on the bottom surface inside the grain storage building body 13. The arc-shaped overlapping pieces 4 on the arc-shaped pipe covers 1 and the overlapping grooves 6 on the arc-shaped bent pipe covers 8 interlock with each other. The arc-shaped overlapping pieces 4 on the arc-shaped bent pipe covers 8 and the overlapping grooves 6 on the arc-shaped pipe covers 1 interlock with each other. Multiple ventilation holes 2 extending to the inside are equidistantly opened on the outer surface of the arc-shaped pipe covers 1. Multiple arc-shaped supporting steel bars 5 are fixed equidistantly on the inner wall of the arc-shaped pipe covers 1. The bottom of the arc-shaped pipe covers 1 is fixed with multiple arc-shaped supporting steel bars 5 near the two side edges. The inner walls of the pad 3 and multiple arc-shaped overlapping pieces 4 are all fixed with arc-shaped rubber sheets 12.
