Description

A kind of silo transversal ventilation system

Technical field

The utility model relates to silo aeration technology field, especially a kind of silo transversal ventilation system.

Background technique

Mechanical ventilation in grain storage is application of the complicated engineering technology in foodstuff preservation, is a Xiang Chong of current foodstuff preservation Technology is wanted, being normally applied for silo mechanical ventilation in grain storage system is to lead to when ambient temperature is lower than cereal temperature using utilizing Cryogenic air is pressed into from the ventilating duct on horizontally disposed ground or is sucked grain heap by blower, air-flow it is vertical or vertically through grain heap again By heat exchange, using heat exchange, by the heat of grain or water transport into air, high temperature air is arranged from grain face or bottom Out, it is discharged in atmosphere by the ventilation opening in silo roof or orlop, achievees the purpose that reduce cereal temperature.The ventilation of silo at present Mode, the draft type of flow are vertically oriented.For the ease of grain export, silo mostly uses greatly gallery ventilation at present System, ground slot form have several forms such as radiation, annular, comb shape, rich shape, F shape air duct.

Since 1998 in the design of new storehouse construction, arrange that two groups there are four branch air ducts to constitute on terrace in silo storehouse Radiation or comb shape air duct.The cover board in geosyncline air duct is frame structure, and segmentation manufacture, every segment length 1m, frame is by channel steel and flat Steel is made, and spreads sieve tray above, and the percent opening of sieve tray is 30%.The top of silo is equipped with natural ventilation port and axial flow blower Ventilation opening.The air inlet of air outlet and drop storehouse temperature ventilation when natural ventilation port is grain heap force ventilation, axial flow blower hole is row Except the air outlet of the top of the warehouse accumulated heat.In use, since grain heap diameter is big, height is high, silo ventilating system exists Wind face is less than normal, and ventilation resistance value is larger, and cooling effect is poor, and the gradation of moisture is big, there are dead corner, ventilation opening quantity it is more, more Blower shares ventilation effect and has no the deficiencies of significantly improving place, and therefore, it is imperative to improve and innovate.

Utility model content

For above situation, for the defect for overcoming the prior art, the purpose of the utility model is just to provide a kind of silo Transversal ventilation system, can effectively solve the problems, such as silo uniformly, high-efficient ventilation.

The technical solution that the utility model solves is:

A kind of silo transversal ventilation system, including silo, the reserves space of the silo inner cavity are that cylindrical body is empty Chamber is respectively arranged with along it circumferentially and mutually the disconnected first cyclic annular main air duct on the side wall of the silo bottom opposite side Liang Zheng With the second cyclic annular main air duct, multiple upward stretchings are provided on the first cyclic annular main air duct and are connected with the first cyclic annular main air duct inner cavity The vertical branch air duct of logical first, be provided on the second cyclic annular main air duct multiple upward stretchings and with the second cyclic annular main air duct inner cavity phase Second vertical branch air duct of connection, the first vertical branch air duct and the second vertical branch air duct are towards on the side of silo center side It is provided with uniformly distributed ventilation hole, the side wall of silo side is provided with the first wind-guiding being connected with the first cyclic annular main air duct inner cavity Mouthful, the side wall of the silo other side is provided with the second air guide hole being connected with the second cyclic annular main air duct inner cavity, silo inner cavity It is filled with grain heap in reserves space, the press mold for sealing grain heap is covered with above grain heap.

The problem of the utility model structure novel is unique, advantages of simple, very good solution silo ventilation, without transformation This body structure of silo directly adds cyclic annular main air duct and vertical branch air duct in two sides, to entire grain heap uniform ventilation, solves Outlet air surface caused by silo diameter is big, height is high is small, ventilation resistance is worth larger and poor cooling effect problem, and there is no logical Wind dead angle, ventilation effect is with the obvious advantage, and whole temperature fall time is short, and lowering temperature uniform is easy to use, and effect is good, is silo ventilation Innovation in system has good social and economic benefit.
