Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Specific implementations of the present invention are described in detail below with reference to specific embodiments.
Example 1
As shown in fig. 1 to 4, a method for arranging a grain ventilation duct according to an embodiment of the present invention includes the following steps:
s101, paving a well-shaped ventilation air duct by using a grain bag 1 filled with grains 2;
s102, covering the grain bag 1 filled with grains 2 on the paved 'well' -shaped ventilation air duct to form a closed ventilation air duct with openings on the periphery;
and S103, finally, carrying out ventilation cooling on the closed ventilation air duct.
Specifically, when the well-shaped ventilation air duct, namely the first layer of grain bags, is laid, the air duct is laid at intervals along the length direction and the width direction of an area to be laid, and the interval distance is determined according to the ventilation efficiency of workers or grain transport machinery and the ventilation air duct. Generally speaking, the interval between two adjacent ventilation wind channels is 4-5m, not only satisfies the demand that the manual work passes through, also satisfies the demand that the machinery passes through, and ventilation efficiency is good. When the device is arranged in a household farm, if the device is limited to the field relationship, the distance between the ventilation air channels can be properly reduced, but the distance cannot be too small, so that the heat volatilized by the grains 2 is prevented from being accumulated in the ventilation air channels and cannot be dissipated. A grain bag 1 filled with grains 2 is covered on the ventilation air duct shaped like a Chinese character jing to form a closed ventilation air duct with openings at the periphery, namely, the construction height of a second layer of grain bag needs to be noticed when the second layer of grain bag is constructed. In general, the sum of the building heights of the first layer of grain bag and the second layer of grain bag does not exceed the height of a person, the building height is too high to facilitate manual inspection of the storage condition of the grain bag 1 at a high position, the building height is too high to meet the requirement on the bearing of the first layer of grain bag, the thickness of a grain bag wall (a wall formed by the grain bags between two adjacent ventilation air channels) needs to be increased, and the excessively thick grain bag wall is not beneficial to ventilation and heat dissipation of grains 2; and thirdly, when the closed ventilation air duct is used for ventilating and cooling, a special grain fan 3 (without excluding other fans) is needed, and in view of the fact that the special grain fan 3 is generally arranged on the horizontal ground, the grain bag 1 at a high position cannot be ventilated and cooled. In most cases, the height of the formed closed ventilation air duct with openings on the periphery is 0.8-1.5 m. The grain bag 1 is 65-75 cm x 110-130 cm in size and can contain 40-50 kg of grains 2. According to the method, the first layer of the grain bag only needs to be paved with 2-4 layers, and the second layer of the grain bag only needs to be paved with 1-3 layers.
According to the invention, the grain bag 1 filled with grains 2 is directly adopted to build the ventilation air duct, the built ventilation air duct not only has four passages and eight directions and is very beneficial to the circulation of air flow, but also utilizes the good ventilation performance of the grain bag to enable air flow to uniformly enter a grain pile, the ventilation effect is good, and in addition, the built ventilation air duct does not adopt a steel support or the like as a support, so that the material consumption is saved and the cost is low. In general, compared with the prior art, the invention has the following beneficial effects:
(1) the ventilation efficiency is high, and the loss of stored grains is small;
(2) the ventilation air duct is formed by building grain bags 1 filled with grains 2, so that large-scale machinery can conveniently transport grains;
(3) the investment cost is extremely low, the operation is convenient, the time and the labor are saved, and the device is suitable for being popularized in novel agricultural operation main bodies such as large grain farmers, family farms, professional cooperative agencies, grain storage and processing enterprises and the like.
Example 2
As shown in fig. 2 to 8, a method for arranging a grain ventilation duct suitable for ventilation treatment of grains in a grain bin according to an embodiment of the present invention includes the following steps:
s201, firstly, filling grains 2 into packaging bags with consistent sizes, and sealing to obtain a large number of grain bags 1 filled with the grains 2; the size of the grain bag 1 is 65-75 cm x 110-130 cm, and 40-50 kg of grains 2 can be contained;
s202, laying 2-4 layers of the grain bag 1 in a one-storey barn from the ground length and width directions of the barn every 4-5m to form a well-shaped ventilation air duct, as shown in figures 5 and 6;
s203, vertically laying 1-3 layers of the grain bag 1 above the Chinese character jing-shaped ventilation air duct, covering and supporting to finally form a closed ventilation air duct with the height of 0.8-1.5m and openings at the periphery, as shown in figure 7;
s204, keeping the width distance of 1-2m between the closed ventilation air channel and the peripheral wall surface of the granary, and plugging the air channel after the granary is filled with grains 2, so that the loss of the air direction around after ventilation is avoided, and the ventilation and cooling efficiency is improved;
s205, finally, installing a special grain fan 3 at each 4-5m ventilation air duct opening in the horizontal direction of the one-storey-house granary, and carrying out ventilation cooling in due time according to the temperature of a grain pile, wherein the grain bag 1 filled with grains 2 has good air permeability, so that air flow uniformly enters the grain pile, and effective cooling and dehumidification are carried out on the grains 2, as shown in fig. 8.
Specifically, the grains 2 are usually stored in a one-storey barn after being purchased and dried by grain enterprises, and ventilation and cooling are carried out timely according to the temperature of grain piles in the grain storage process, so that the grains 2 are prevented from being moist and mildewed. The invention changes the traditional measure of arranging the ventilation air channel by adopting a mechanical device, directly adopts the grain bag 1 filled with grains 2 to build the ventilation air channel, and the built ventilation air channel not only has four-way and eight-way and is very beneficial to the circulation of air flow, but also utilizes the good ventilation performance of the grain bag to ensure that the air flow uniformly enters the grain pile and has good ventilation effect. Compared with the prior art, the invention has the following beneficial effects:
(1) the ventilation efficiency is high, and the loss of stored grains is small;
(2) the ventilation air duct is formed by building grain bags 1 filled with grains 2, so that large-scale machinery can conveniently transport grains;
(3) the investment cost is extremely low, the operation is convenient, the time and the labor are saved, and the device is suitable for being popularized in novel agricultural operation main bodies such as large grain farmers, family farms, professional cooperative agencies, grain storage and processing enterprises and the like.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
