Problems solved by technology

In addition, none of the air supply pipes, return air pipes, and probes in this patent are in contact with the warehouse wall, that is, they are not fixed on the warehouse wall, or they need to be installed while feeding grain, or after loading grain, which will increase the work of grain storage strength

Embodiment 1

[0035] Example 1: Transverse ventilation to reduce grain temperature

[0036] Such as figure 1 , figure 2 As shown, the granary transverse ventilation system provided by the present invention includes a granary 1, a ventilation duct 2 (including a main ventilation duct 21 and a branch ventilation duct 22), a plurality of ventilation duct openings 3, a sealing film 4 covering the surface of the grain pile, and a sealed bulk Grain pile 5, a ventilator 6 arranged outside the granary; inside the two longitudinal walls 11 of the granary 1 is provided with a ventilation duct 2, the height of the ventilation duct 2 is lower than the height of the grain pile 5 by 10-1000 mm, the ventilation The duct 2 is composed of a main ventilation duct 21 and a branch ventilation duct 22. The main ventilation duct 21 communicates with the ventilation duct opening 3 on the same side longitudinal wall 11, and at least one branch ventilation duct 22 is provided on the main ventilation duct 21. The bran...

Embodiment 2

[0041] Example 2: Horizontal circulation uniform temperature ventilation operation

[0042] Such as image 3 , Figure 4 As shown, the granary transverse ventilation system provided by the present invention includes a granary 1, a ventilation duct 2, a plurality of ventilation passage openings 3, a sealing film 4 covering the surface of the grain pile, a sealed bulk grain pile 5, and a ventilator 6 arranged outside the granary. ; Inside the two gables 11 of the granary 1 is provided with a ventilation channel 2, the height of the ventilation channel 2 is 10 ~ 1000 mm lower than the height of the grain pile 5, the ventilation channel 2 is a fully-opening ventilation channel, and buckle On the two gables 11, the surface of the ventilation duct is provided with ventilation holes 221, and the aperture of the ventilation holes 221 is smaller than grains. The ventilation duct 2 is connected with the ventilation duct opening 3 on the same side gable 11, and the ventilation duct 2 The s...

Abstract

The invention discloses a granary lateral ventilation method and a system thereof. In the invention, a ventilation tunnel is arranged on the inside wall of the granary which covers a sealing film on the surface of grain, lateral ventilation is carried out on all grain piles in the granary. Compared with cage on the ground and geosyncline vertical ventilation system in the granary, the ventilationtunnels are small in quantity, ventilation way ratio is small, ventilation uniformity is good, ventilation dead corner is hardly existed, ventilation efficiency is high and energy consumption is low.Besides, installation or disassemble of cage on the ground for transporting the grain in and out in the prior art is avoided. The grain terrace is not provided with a ventilation tunnel in any form and the terrace is complete, thus being convenient for mechanized grain transportation, lowering the labor intensity of grain transporter and saving time for grain transportation.

Description

Technical field [0001] The invention relates to a granary lateral ventilation method and a system thereof, belonging to the technical fields of agricultural machinery engineering, agricultural product processing and storage engineering, and grain and oil storage engineering. Background technique [0002] Mechanical ventilation technology, as a traditional grain storage technology and one of the “four new grain storage technologies” in my country’s newly built grain depot in 1998, has been widely used in modern grain depots. The currently used grain storage ventilation system is mainly composed of fans and granaries. The main function of the ventilation duct arranged on the ground and the warehouse filled with grain is to use the ventilator to make the outside low temperature air pass through the grain pile and reduce the grain temperature. In addition to the above functions, the system also has the function of balancing grain temperature and reducing or increasing grain moisture. ...
