A grain drying system combined with solar hot water circulation pipe network and hot air

Abstract

The invention discloses a solar hot water circulation pipe net and hot air combined cereal drying system. A drying chamber is included. The end, away from bases, of the drying chamber is provided witha hot water tank, and a solar panel is arranged above the hot water tank. A hot water circulation pipe net is arranged on the inner wall of the drying chamber, a hot air branch pipe at the middle position is parallel to the bottom wall of the drying chamber, the included angle between hot air branch pipes away from the center position and the bottom wall of the drying chamber is sequentially increased, and an adjusting plate is movably arranged in a center hot air pipe. An air cylinder shaft is fixedly provided with a large baffle in a penetrating manner, and a plurality of stirring rods arefixedly arranged on the bearing plate. The solar hot water circulation pipe net and hot air combined cereal drying system is provided, the solar hot water circulation pipe net and hot air combined cereal drying system is utilized and internally provided with a device for overturning cereal and limiting the hot air range, mutual supplementing is achieved, heat is effectively utilized, heat losses are few, cereal drying is more uniform, and efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of grain drying, in particular to a grain drying system combining a solar hot water circulation pipe network and hot air. Background technique [0002] In the prior art, a grain drying ventilation system and a grain dryer with the application number "201821149924.8" include an air mixing chamber assembly and a hot air chamber assembly, and the air mixing chamber assembly and the hot air chamber assembly are connected. Among them, The air mixing chamber assembly includes a mixing air box. The bottom of the mixing air box is provided with a hot air inlet, and the hot air inlet is provided with a shroud; bellows. The grain drying machine includes the grain drying ventilation system, the grain drying ventilation system and the grain drying machine can fully mix the external cold air with the hot air guided by the shroud, which is beneficial to realize the uniform temperature of the mixed hot air.

Problems solved by technology

[0003] However, there are still obvious defects in its use: 1. The above-mentioned device only mixes hot air and cold air before the hot air blows to the grain, but when the mixed wind blows to the grain, due to the lighter density of the hot air , will still float to the upper layer, causing the grains accumulated at the bottom to be unable to be evaporated and dried by the hot air, and the utilization rate of the hot air is low; Hot air treatment tends to cause the surface to be too dry and the interior to be too humid, resulting in uneven drying and affecting grain storage
