TECHNICAL FIELD
[0001] The utility model belongs to the technical field of grain storage, specifically belongs to a kind of grain heap deep water conservation cooling ventilation device. BACKGROUND
[0002] Grain is stored in granary to form grain heap, due to the uncertainty factor of grain heap, such as pest, bottom moisture penetration and the like, when grain is safe in summer, local nest-like heating phenomenon can appear in grain heap bottom layer, since heating site is in the bottom layer of grain heap, conventional single-pipe fan ventilation cannot reach effective depth to carry out ventilation treatment, if centrifugal fan or axial flow fan is used to carry out whole warehouse ventilation treatment, it can damage the whole grain storage ecological environment, cause whole warehouse temperature abnormality and excessive water loss. UTILITARY MODEL CONTENT
[0003] Therefore, the utility model aims at overcoming the deficiencies in the prior art, and provides a grain heap deep water conservation cooling ventilation device, and the following technical scheme is provided in the application:
[0004] A grain heap deep water conservation cooling ventilation device, comprising a fan, an air distribution box and a plurality of metal ventilation pipes, the fan is connected with the air inlet of the air distribution box, the air distribution box is provided with a plurality of air outlets, each air outlet is connected with one end of a metal ventilation pipe, and the other end of the metal ventilation pipe is arranged in the grain heap.
[0005] In one possible embodiment, the metal ventilation pipe is connected with the air outlet of the air distribution box through a hose.
[0006] In one possible embodiment, one end of the metal ventilation pipe arranged in the grain heap is provided with a triangular opening.
[0007] In one possible embodiment, the plurality of metal ventilation pipes are arranged side by side, and the distance between two adjacent metal ventilation pipes ranges from 4cm to 50cm.
[0008] In one possible embodiment, each metal ventilation pipe comprises a plurality of metal pipes connected through joints.
[0009] As the above technical scheme is adopted, the utility model has the following beneficial effects:
[0010] The utility model discloses a grain stack deep layer water conservation cooling ventilation device, including fan, air distribution box and a plurality of metal ventilation pipe, they intercommunicate, when using, through the deep layer sampler, the metal ventilation pipe is down to the grain stack bottom, the upper end of metal ventilation pipe is connected to the air distribution box, every air distribution box can connect 5-6 metal ventilation pipes, then uses the low -power fan and carries out the ventilation treatment to reach the grain stack deep layer ventilation cooling effect, therefore through the metal ventilation pipe can effectively solve the ventilation dead angle phenomenon that appears when the storage grain warehouse ventilation accumulates cold, simultaneously the utility model can also avoid appearing for reducing local bottom layer heating phenomenon, and using centrifugal fan causes the excessive loss of grain moisture, or adopts the valley cold machine and produces a large amount of expense.
