Description

Grain Dryer with Batch Feed Automatic Cycle

technical field

The utility model relates to a grain drying machine, in particular to a grain drying machine which feeds in batches and automatically circulates.

Background technique

In the process of grain drying, the traditional method is to use the sun. At present, grain dryers are widely used in large-scale grain planting farms. The grain dryer is a drying equipment that uses hot air for forced drying, which can be independent of meteorological conditions. Dry the harvested grains into storage at any time. Grain dryers generally use a hoist to lift the grain, and dry it with hot air through repeated cycles of the grain. With the large concentration of grain planting area and the wide application of mechanization in harvesting, the tradition of relying on solar energy to dry grain The method has been unable to adapt to the current wet grain treatment, and the grain dryer has also emerged as the times require. The principle is to use oil mist to burn to heat the air, blow it into the drying bin that can evenly roll the grain with high water content up and down, and then use A device for suction, grading, layering and forced drying by induced draft fan. The main disadvantages of the above-mentioned grain dryers are that due to the insufficient utilization of waste heat, the shortage of fuel oil and the high cost,

Contents of the invention

The purpose of this utility model is to provide a batch-feeding automatic circulation grain dryer suitable for natural gas, coal, rice husk, etc. as fuels for the shortcomings of the above-mentioned grain dryer.

In order to achieve the above object, the utility model mainly adopts the following technical solutions to realize. The utility model is mainly composed of the drying layer of the grain dryer and the storage room above the drying layer. A bucket elevator is arranged outside the grain dryer. The two ends of the bucket elevator are respectively the feeding hopper and the The discharge hopper is provided with a lower spiral conveying pipe at the lower end of the bucket elevator, and an upper spiral conveying pipe at the upper end of the bucket elevator. Below the grain dryer, there is a combustion furnace in front of the drying layer. The combustion furnace can use natural gas, coal or rice husk as raw materials. Below the grain dryer, there is also a single-board simple computer controller. An induced draft fan is installed behind the drying layer, a waste heat circulation pipe is installed under the grain dryer, inside and below the drying layer, and a high-efficiency dust exhauster is installed above the grain dryer.

Compared with the prior art, the utility model has the following obvious advantages and progress. (1) The combustion furnace designed by the utility model can be applied to local materials such as natural gas, coal and rice husk, waste utilization and energy saving, which can increase the adaptability of various places and reduce user costs. (2) The waste heat is recycled again, which promotes the hot air to circulate in all directions, eliminates dead angles, makes the grains heated evenly, and saves the time required for batch drying. (3) A single-board simple computer controller is added to automatically monitor the failure of the internal circulation system. Control the flow rate of the axial flow fan to use the hot air evenly and effectively to increase the drying speed. (4) The utility model has the advantages of short drying time, reliable and easy control, obvious dust removal and environmental protection effect, low failure maintenance rate, and strong combustion adaptability. (5) The utility model is also applicable to the use of other fuels except fuel oil.

The utility model is suitable for drying grains.

The utility model is described in further detail in the following structural drawings and specific embodiments.
