Description

A Grain Dryer with Double Circulation Air Duct

technical field

The utility model relates to the technical field of grain drying, in particular to a grain dryer with double circulation air ducts.

Background technique

At present, the hot air duct of the existing grain dryer generally uses one end to enter the hot air, and the hot air passes through the entire dryer and then blows out from the other end. The disadvantage of this circulation method is: the hot air blows from the front end to the rear end, and the wind speed is too fast , cannot fully exchange heat with the grain, the hot air is taken out by the fan, wasting energy, the drying effect is not ideal, and the drying effect in the entire dryer is not uniform enough.

Utility model content

The purpose of the utility model is to solve the above-mentioned technical problems and provide a grain dryer with double circulation air ducts.

The utility model includes a support, an outer drum, an inner cylinder, a windshield partition and an air supply module. The two ends of the inner cylinder are respectively provided with hot air inlets, and the body of the inner cylinder is provided with a group of air vents. The windshield The partition is fixedly installed in the middle of the inner cylinder and divides the inner space of the inner cylinder into two parts. The outer cylinder is provided with a grain inlet, a grain outlet and an air outlet, and the two ends of the outer cylinder are respectively installed on the On the support, the outer roller is set outside the inner cylinder, and the inner wall of the outer roller and the outer wall of the inner cylinder form a grain drying channel. The air supply module includes a pair of hot air blowers and an air outlet pipe. The hot air of the pair of hot air blowers The outlets communicate with the hot air inlets at both ends of the inner drum through pipes, and the air outlet pipes communicate with the air outlets on the outer drum.

The windshield partition divides the inner space of the inner cylinder into two equal independent spaces.

The grain inlet on the outer drum is located at the top of one side of the outer drum, and the grain outlet on the outer drum is located at the bottom of the other side of the outer drum.

The outer wall of the outer drum is also wrapped with an insulating layer.

The utility model has the advantages that: the utility model provides a grain dryer with a double-circulation air duct, a windshield partition is set in the middle of the air inlet inner cylinder, the air inlet mode adopts two ends of the air inlet, and the inner cylinder dries the grain The way of uniform air distribution in the channel makes the temperature of the hot air in the entire grain drying channel uniform. According to the size of the output, the return hot air with water droplets is automatically adjusted when it passes through the return pipe, which can reduce the breakage rate and ensure grain drying. The effect is more ideal, and it has good practical and popularization value.

detailed description

As shown in Figure 1, the utility model includes a support 1, an outer drum 2, an inner cylinder 3, a windshield partition 4 and an air supply module. The cylinder body is provided with a group of air vents, the windshield partition 4 is fixedly installed in the middle of the inner cylinder 3, and divides the inner space of the inner cylinder 3 into two, and the outer cylinder 2 is provided with a grain inlet and a grain outlet and the air outlet, the two ends of the outer drum 2 are movably installed on the support 1 through the bearing seat, the outer drum 2 is set outside the inner drum 3, and the inner wall of the outer drum 2 and the outer wall of the inner drum 3 form a grain drying channel, so The air supply module includes a pair of hot air blowers 5 and an air outlet pipe 6. The hot air outlets of the pair of hot air blowers 5 communicate with the hot air inlets at both ends of the inner cylinder 3 through pipes respectively. The air outlets are connected.

The windshield partition 4 divides the inner space of the inner cylinder 3 into two equal independent spaces.

The grain inlet on the outer drum 2 is located at the top of one side of the outer drum 2 , and the grain outlet on the outer drum 2 is located at the bottom of the other side of the outer drum 2 .

The outer wall of the outer drum 2 is also wrapped with an insulating layer.

Working method and principle: a pair of hot air blowers 5 respectively inject hot air into the hot air inlets at both ends of the inner cylinder 3, and the hot air runs into the inner cylinder 3, and flows outward through a group of vents on the body of the inner cylinder 3 to the inner wall of the drum 2 and The air distribution in the grain drying channel formed by the outer wall of the inner cylinder 3 is uniform, and the setting of the windshield partition 4 avoids the disadvantages of excessively long hot air circulation and uneven hot air. The hot air passes through the air outlet pipe after passing through the grain drying channel 6 pass out.
