Description
Technical field
The utility model relates to a kind of three-dimensional intubate ventilating system, belong to agricultural engineering, agro-product processing storage engineering and grain and oil storage field of engineering technology.
Background technology
Grain is the most basic means of livelihood of the mankind, and it is related to the stable and development of the stable of society and national economy.China is the country that world population is maximum, because of the restriction of the conditions such as weather, arable land, economic development, determining the dependence food import ensureing that supply of food can not be too much, can only ensure supply of food in the method by improving foodstuff preservation.
The method of foodstuff preservation is a lot.Force ventilation technology, as a kind of grain storage technology of science, is a key technology in foodstuff preservation process.Its major advantage of force ventilation technology is that equipment is simple, easy to operate, small investment, by the restriction of warehouse condition, be easy to promote in different regions.Force ventilation technology can make grain pile and realize relative low temperature or accurate low-temperature condition, thus effective development and the harm controlling entomophthora, reduce the transfer of moisture in grain heap, increase the stability of foodstuff preservation, the one-tenth of delay grain quality, keep the freshness of grain.The extensive use in the modern grain depot of China of current force ventilation technology, practice for many years shows, although mechanical ventilating storage grain technology achieves some economic benefits and social benefit, still has a lot of aspect to constantly bring forth new ideas.
Current large storehouse force ventilation mainly adopts air channel, ground draft type, under warehouse terrace, namely excavates flute profile air channel or on terrace, lay cage type air channel, and some air channels are connected the net that becomes a common practice, then is connected with blower fan outside storehouse, forms ventilating system.On the ground to reduce grain temp effect better for cage ventilating system, when maximum bottleneck is to carry out drying operation for high grain heap (grain referred generally to higher than 3m pile), there will be the too dry and phenomenon that upper strata moisture declines not yet of lower floor's grain, cause moisture distribution of grain inequality.Therefore, " mechanical ventilation in grain storage technical regulation " specifies: when mechanical ventilation in grain storage is used for drying generator, and grain heap tall and bigly should not be greater than 3m, otherwise there will be Liang Dui lower floor super-dry and upper strata moisture does not decline, the phenomenon of grain heap vertical direction moisture distribution inequality.But state's bank large storehouse newly-built at present is mostly pressed 6m and piled the design of grain line, if high 3m is only piled in the requirement meeting drying generator uniform moisture, huge capacity waste can be caused, and be unfavorable for the grain face operation of real storehouse.
In recent years part grain storage enterprise adopts vertical cannula ventilation to carry out cooling precipitation ventilation experiment to high grain heap.Vertical cannula aeration technology makes air pass the technology of grain heap by the airduct of each vertical distribution in grain heap inside that grain heap surface level air channel connects.Because vertical airduct is densely distributed relative to ground upper air duct, after drying generator, grain moisture content is comparatively even, and reduce most dead corner, drying effect improves a lot.But vertical cannula ventilation operation amount is large, labour intensity is high, and the disposable input of equipment such as to lose more greatly and easily at the series of problems, and in practical work process, large-scale popularization carries out in-store drying not yet at home.
For the series of problems of vertical cannula, the present invention proposes a kind of novel three-dimensional intubate draft type, adopt novel " Gui " type air channel, and in conjunction with necessary instruments such as electric inserting drawbenches, realize whole storehouse mobile three-dimensional dry, to be characterized in use procedure without the need to layering tube drawing, to reach the object alleviating workload, improve drying efficiency.
Summary of the invention
