DETAILED DESCRIPTION
[0029] The embodiments of the present application will be described in detail by the specific embodiments, and the person skilled in the art can easily understand other advantages and effects of the present application from the disclosed content. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor shall belong to the scope of protection of the present application.
[0030] The outdoor rainproof constant-temperature air-drying bin provided by the embodiment comprises a shell 1 and an intermediate inner container 2. In the embodiment, the shell 1 and the intermediate inner container 2 are both cylindrical, the intermediate inner container 2 is arranged inside the shell 1, and is coaxially installed along the center line of the shell 1. At the lower end of the shell 1, a collector 4 is arranged between the shell 1 and the intermediate inner container 2. In the embodiment, there are six collectors 4, each collector 4 is funnel-shaped, large at the top and small at the bottom, and is sequentially and adjacently arranged to form a ring structure and is connected to the cavity between the shell 1 and the intermediate inner container 2. The lower end of each collector 4 is connected to a grain self-flow pipe 5, and the lower ends of the grain self-flow pipes 5 are integrated to form a grain outlet 6. A flat conveyor 7 is arranged below the grain outlet 6.
[0031] The side wall of the shell 1 can be uniformly or non-uniformly provided with air holes.
[0032] The side wall of the intermediate inner container 2 is made of a breathable material, which includes but is not limited to a perforated plate, a wire mesh, etc. The lower end of the intermediate inner container 2 is provided with an air outlet pipe 8 connected to the air inlet of a moisture removal fan 9, and the air outlet of the moisture removal fan 9 is connected to a moisture removal air pipe 10. The upper portion of the intermediate inner container 2 is provided with a flow divider tower 3, which can prevent the grain from directly falling into the intermediate inner container 2 and uniformly distributing in the cavity between the shell 1 and the intermediate inner container 2.
[0033] In order to avoid the influence of lateral pressure on the grain particles, causing the grain near the side wall in the bin to flow downward unsmoothly, thereby ensuring that the grain in the bin can flow downward smoothly and evenly, the outdoor rainproof constant-temperature air-drying bin further comprises a flow director 41, which is conical and is arranged at the inlet of each collector 4 with the tip upward. Meanwhile, the grain outlet flow director 61 is arranged in the grain outlet 6, which is conical and is arranged in each grain outlet 6 with the tip upward.
[0034] The outdoor rain-proof constant-temperature air-drying bin also comprises a grain lifting machine 11, and the grain conveying pipe of the grain lifting machine 11 is aligned above the shunt tower 3. When fragile materials such as melon seeds are stored in the bin, the use of the grain lifting machine 11 is likely to cause the materials to be crushed. Other devices can also be used to lift the materials, such as a belt conveyor.
[0035] The moisture-removing fan 9 can be a blower fan, which blows air into the middle inner container 2 through the air outlet pipe 8. The air further passes through the side wall of the middle inner container 2 and then uniformly passes through the gaps between the grain particles in the bin, and finally overflows the air-drying bin from the opening at the upper part of the outer shell 1 or the air vent on the side wall of the outer shell 1, thereby taking the moisture in the grain out and rapidly reducing the water content of the grain.
[0036] When the environmental humidity is high, the moisture-removing fan 9 can be used in cooperation with a gas drying device, so that dry gas can be blown into the air-drying bin to increase the efficiency of moisture removal.
[0037] When the environmental temperature is too low, the moisture-removing fan 9 can be used in cooperation with a gas heating device, so that warm gas can be blown into the air-drying bin to increase the efficiency of moisture removal.
[0038] Of course, the fan can also be a suction fan, which can suck out the humid air from the air-drying bin, and also can rapidly reduce the water content of the grain.
[0039] The outdoor rain-proof constant-temperature air-drying bin also comprises a rain-proof heat preservation cover, which is used to prevent the air-drying bin from being affected by the environmental humidity and high and low temperatures.
[0040] The working process of the outdoor rain-proof constant-temperature air-drying bin is as follows: the grain is conveyed into the outer shell 1 by the grain lifting machine 11, and after being shunted by the shunt tower 3, the grain is accumulated in the annular cavity between the outer shell 1 and the middle inner container 2. The moisture-removing fan 9 is started to make the air uniformly pass through the gaps between the grain particles and absorb the moisture in the grain, forming humid air, which is then discharged from the air-drying bin. The dried grain flows out from the grain outlet 6 after passing through the collector 4 and the grain self-flowing pipe 5, and then is conveyed to the inlet of the grain lifting machine 11 by the flat conveyor 7, so that the grain in the bin circulates and repeatedly removes moisture. Alternatively, the grain in the bin can be conveyed to a packaging process for packaging and delivery.
[0041] The above is only a preferred embodiment of the present application, and is not used to limit the protection scope of the present application. Any skilled person in the art can make equivalent transformations to the present application by using the above technical solutions without departing from the protection scope of the present application. The protection scope of the present application is subject to the contents recorded in the claims.
