Embodiment 1

[0035] Example 1: Transverse ventilation reduces grain temperature

[0036] Such as figure 1 , figure 2 As shown, the granary horizontal ventilation system provided by the present invention includes a granary 1, an air duct 2 (comprising a main air duct 21 and a branch air duct 22), a plurality of air duct openings 3, a sealing film 4 covered on the grain pile surface, sealed bulk Grain pile 5, ventilator 6 that is arranged outside the granary; An air passage 2 is arranged inside the two longitudinal walls 11 of the granary 1, and the height of the air passage 2 is 10-1000 mm lower than the height of the grain pile 5. Road 2 is made up of main air passage 21 and branch air passage 22, and described main air passage 21 is connected with the air passage opening 3 on the warehouse wall 11 of the same side with it, and at least one branch air passage 22 is set on this main air passage 21, and this The branch air passage 22 is a pipe with a circular cross-section, with ventilati...

Embodiment 2

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

[0042] Such as image 3 , Figure 4 As shown, the granary horizontal ventilation system provided by the present invention includes a granary 1, an air channel 2, a plurality of air channel openings 3, a sealing film 4 covered on 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, an air duct 2 is provided, the height of the air duct 2 is 10-1000 mm lower than the height of the grain pile 5, and the air duct 2 is a full-open air duct, and is buckled On the two gables 11, the surface of the ventilation channel is provided with a ventilation hole 221, and the aperture of the ventilation hole 221 is smaller than the grain. The surface of the air duct is 50-1000 mm away from the wall, and the ventilation channel is vertically arranged to the ground. The ventilator 6 arranged outside the granar...

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 ventilation tunnels 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 horizontal 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" newly built in my country in 1998, has been widely used in modern grain storage. It is composed of ventilation ducts arranged on the ground and warehouses filled with grain. The main function is to use the ventilator to let the outside low-temperature air pass through the grain pile to reduce the temperature of the grain. In addition to the above functions, the system also has the function of balancing grain temperature and reducing or increasing grain moisture. At the same time, the system can also be shared by grain coolers, phosphine circulat...
