Waste heat recovery equipment for grain dryer processing

Abstract

The invention provides waste heat recovery equipment for grain dryer processing, and relates to the technical field of grain dryers. The waste heat recovery equipment for grain dryer processing comprises a box body and a fixed base. The inner bottom wall of the box body is fixedly connected with a dust removal box, the bottom of the dust removal box communicates with a blow-off pipe, the interiorof the dust removal box is fixedly connected with an activated carbon layer, and one side of the dust removal box communicates with an air inlet pipe. A first motor drives a first rotating plate to rotate, a second motor drives a second rotating plate to rotate, a third motor drives a third rotating plate to rotate, and a fourth motor drives a fourth rotating plate to rotate so that the hot air passing path can be changed, and the time for hot air to pass through a recycling box can be controlled. And the flowing paths of hot air at different temperatures can be changed by adjusting the firstrotating plate, the second rotating plate, the third rotating plate and the fourth rotating plate to rotate, so that the efficiency and effect of recovering the heat of the hot air at the different temperatures by water in the recycling box are guaranteed.

Description

technical field [0001] The invention relates to the technical field of grain dryer processing, in particular to waste heat recovery equipment for grain dryer processing. Background technique [0002] Grain dryer refers to a hot air drying box, which adopts a rotary heating device, which can generate a large amount of hot air in a short period of time. It can kill insect eggs through high temperature treatment and completely solve the problem of grain drying; [0003] Chinese patent (notification number: CN211717127U, announcement date: 2020.10.20) discloses a waste heat recovery device for grain dryers, including: a heat exchange device and an exhaust channel, one end of the exhaust channel is connected to the dryer outlet, and the other end Connect the heat exchange air inlet of the heat exchange device. The heat exchange device includes a box body and a heat exchange coil installed in the box body. The two ends of the heat exchange coil out of the box are respectively con...
