Problems solved by technology
However, during the application process, it was found that due to the limitation of installation conditions and transportation capacity, this kind of equipment cannot be too high, generally only about 30 meters, and its operation will be affected to a certain extent when the wind force above is particularly small
Especially in the cold winter, the grain moisture freezes, even if there is wind, it is difficult to achieve the purpose of dehydration

Embodiment Construction
[0016] The first embodiment: as figure 1 , 2 As shown, this air-drying tower 2 is up to 30m, and the tower body is sealed by shell, and opening up and down, there is support 1 under the tower, there is upper grain pipe 4 on it, and a plurality of upright grain boxes 3 are arranged in the tower. combine image 3 Visible, two case walls of grain tank 3 are made of screen cloth, and the shell of air-drying tower 2 can be utilized in the other two sides, grain tank 3 preferred height 30m, thick 10cm, sieve hole size is degree with not leaking grain grain. Grain is loaded into grain tank 3 by grain pipe 4, and air duct 5 is between each grain tank 3. Due to the high wind speed at the top of the tower, the airflow in the air duct 5 can be driven upward at high speed. On one side of the grain tank 3, a box-shaped natural wind cover 6 is buckled, and the loam cake, both sides and the front of the natural wind cover 6 are sealed, and the natural wind inlet 9 is arranged below. The ...

The invention relates to grain storage equipment, namely a grain dryer utilizing the complementation of wind and heat, which is a wind drying tower (2) with an opened upper part and an opened lower part. At least one vertical grain box (3) enclosed by a sieve is arranged in the tower, and a wind channel (5) is arranged at the outer side of the grain box (3). The grain dryer is characterized in that a natural wind cover (6) is arranged at one side of the grain box (3), and a wind supplementing cover (7) is arranged at the other side of the grain box (3). A natural wind inlet (9) is arranged below the natural wind cover (6), and an upper cover is separated from the grain box (3) by a certain distance. The wind supplementing cover (7) is a sealed box type container which is enclosed by a thin plate and buckled at the lower part of the other side of the grain box (3), a wind supplementing port (10) is communicated in the box and connected with a wind supplementing pipe (8), and the wind supplementing pipe (8) extends out of the tower and is connected with a blower. The grain dryer has the beneficial effects of being capable utilizing natural wind, supplementing wind power manually andadjusting temperature, serving as an all-weather grain dewatering device suitable for various regions, not only being suitable for small-scale dispersing interval operation, but also meeting the demands of large-scale concentrated continuous operation, and being capable of replacing the existing machine of the similar type to become an important device for grain storage.
Description
technical field [0001] The invention relates to a grain storage device, namely a wind-heat complementary grain dryer. Background technique [0002] Corn and other grains must be dehydrated and dried before storage to reach a safe water content, so as to prevent mildew and deterioration during storage. In the past, grain drying was mainly done by natural drying, which took up a lot of space, took a long time, and caused a lot of losses, making it difficult to meet the needs of centralized grain storage and transportation. In order to solve this problem, in recent years, people have used grain drying towers to dehydrate grain and achieved good results. However, the grain drying tower needs to use coal or electricity as the heat source, which consumes a lot of energy and is a high-carbon operation. In order to save coal and electricity resources, someone has developed a kind of elevated natural air-drying equipment, which is to put grain into a sieve-shaped container with a c...
