The ventilation pipe comprises an upper pipe, a plurality of middle pipes and a lower pipe which are sequentially fixed in series, the lower pipe is fixed on the static air box, the cover is fixed on the upper pipe, and the upper pipe, the middle pipes and the lower pipe are collectively called as a ventilation pipe unit.

The fixed grafting between the ventilation pipe unit specifically is: the lower end of the upper ventilation pipe unit is sleeved at the upper end of the lower ventilation pipe unit sleeve.

The ventilation pipe unit is fixed through the flange, specifically is: the lower extreme of upper tube, the both ends of intermediate tube, the upper end of lower tube all fixed flange dish, and the ring flange is equipped with a plurality of through-holes, and through the bolt fastening who wears to establish in the through-hole between two adjacent ring flanges, be equipped with a plurality of support columns between the ring flange of two tip of same intermediate tube, these support columns distribute on a space column face.

A plurality of supporting columns are arranged between the flange of the lower pipe and the upper surface of the static air box, and the supporting columns are distributed on a spatial cylindrical surface.

Compared with the prior art, the technical effect of the utility model is that, the utility model discloses be equipped with the effective ventilation that ventilation pipe, the radial ventilation hole of cooperation can keep the grain hoarding, maintain the safety that the grain hoarding.

Detailed Description

Referring to fig. 1-3, a ventilation device for a grain bin comprises a static air box 5, wherein the static air box 5 is communicated with an air inlet pipe 6 and a ventilation pipe, the air inlet pipe 6 is integrally and horizontally arranged, the outer end part of the air inlet pipe is provided with an air blower connector 7, the air blower connector 7 is positioned on the outer side of the grain bin, the ventilation pipe is integrally and vertically arranged, the pipe wall of the ventilation pipe is provided with a plurality of radial ventilation holes (not shown in the figure), the upper end of the ventilation pipe is fixedly provided with a cover 1, the cover 1 can prevent grains from falling into the ventilation pipe when the grain bin is filled with grains, and can also send.

In order to adapt to different heights of the grain bin, the ventilating pipe is split. The ventilation pipe comprises an upper pipe 2, a plurality of middle pipes 3 and a lower pipe 4 which are sequentially fixed in series, the lower pipe 4 is fixed on a static air box 5, a cover 1 is fixed on the upper pipe 2, and the upper pipe 2, the middle pipes 3 and the lower pipe 4 are collectively called as a ventilation pipe unit.

To match more height levels there are two ways of fixing between ventilation duct units.

When the height is low, the first is used: the fixed grafting between the ventilation pipe unit specifically is: the lower end of the upper ventilation pipe unit is sleeved on the upper end of the lower ventilation pipe unit sleeve, see fig. 2.

When the height is low, the second is used: the ventilation pipe unit is fixed through the flange, specifically is: referring to fig. 3, flanges 42 are fixed at the lower end of the upper pipe 2, at the two ends of the middle pipe 3 and at the upper end of the lower pipe 4, a plurality of through holes 43 are formed in the flanges 42, two adjacent flanges 42 are fixed through bolts penetrating through the through holes 43, a plurality of support columns 44 are arranged between the flanges 42 at the two ends of the same middle pipe 3, and the support columns 44 are distributed on a spatial cylindrical surface.

When the height is low, the risk of the ventilation tube itself is low, and the first one can be used to save material.

When the height is low, the risk level of the ventilation pipe is high, and by adopting the second structure, the flange plate can resist axial pressure, and the support column 44 can resist bending moment, so that the safety of the ventilation pipe is maintained.

In order to reinforce the fixing of the ventilation pipe to the static bellows 5, a plurality of support columns 44 are provided between the flange 42 of the lower pipe 4 and the upper surface of the static bellows 5, and the support columns 44 are distributed on a spatial cylindrical surface.

The working principle is as follows:

before the grains are put into the bin, the static air box 5 is arranged in the middle of the bottom surface of the grain bin, the air inlet pipe 6 is led out to the outer side of the grain bin, the cover 1 is fixed on the upper pipe 2, and then the grains are put into the bin from the upper side.

After warehousing, if ventilation is needed, the air blower connector 7 is connected to the air blower, the air blower sends normal-temperature air into the static air chamber, the static air chamber supplies air upwards through the ventilation pipe, the air rushes out from the radial ventilation pipe and enters grains, heat in the grains is taken out, and safety of the grains is maintained.

Other content participates in the prior art.

While only the preferred embodiments of the present invention have been described, it is to be understood that various changes and modifications may be made therein by those skilled in the art without departing from the general concept of the invention, and it is intended to cover all such changes and modifications as fall within the scope of the invention.
