Abstract

The invention discloses a solar energy heat pipe type grain dryer which is composed of a solar heat collection plate, heat pipes, a heat pipe fixed framework and movable boxboards to achieve drying of grain. The solar energy heat pipe type grain dryer is characterized in that the heat pipe fixed framework is arranged on the back of the solar heat collection plate, a plurality of the heat pipes are arranged on the framework, wherein an inclined angle with a certain of angles exists between the horizontal plane of the framework and each heat pipe, one face of the framework pressing close to the solar heat collection plate is an integral metal plate, a few of portions of one end of each heat pipe penetrate through the metal plate, a sunny side of the metal plate and the portions of the heat pipes penetrating through the metal plate are all coated by heat absorption coatings, and the other end of each heat pipe is fixed at the portion of the framework opposite to the metal plate. A fan is further arranged on the framework. A purpose-made pallet is arranged on each heat pipe. The movable boxboards are arranged on all faces of the heat pipe fixed framework in a hanging mode, namely, a drying box body is formed. The grain is put in the purpose-made pallets in the drying box body, the solar heat collection plate obtains heat, the heat pipes quickly absorb the heat and transfer the heat, and then temperature in the drying box body rises and the fan is opened, and thereby the grain is quickly dried.

Description

Solar heat tubular type grain dryer

Technical field:

The present invention relates to a kind of solar heat tubular type grain dryer, is to utilize solar heat-collection plate, heat pipe, heat pipe fixed frame, movable boxboard, heat absorbing coating, purpose-made pallet, fan and come the cereal on the drying box purpose-made pallet of putting into solar heat tubular type grain dryer is realized dry by the drying box that movable boxboard forms.

Background technology:

Present solar energy cereal is dry, be that large-scale drier has all added a lot of power set basically, and solar energy utilization ratio is low, and the cereal that is not suitable for small lot is dry.

Summary of the invention:

The object of the invention provides a kind of solar heat tubular type grain dryer of suitable small lot cereal drying, to take full advantage of solar heat-collection plate to obtain heat, the heat absorption of heat pipe, heat transfer rate make soon that temperature raises fast in the drying box that is formed by movable boxboard, and the purpose-made pallet that cereal is put on the solar heat tubular type grain dryer drying box heat pipe can be dried fast.

The object of the present invention is achieved like this:

A kind of solar heat tubular type grain dryer, it has solar heat-collection plate, heat pipe fixed frame, movable boxboard, heat absorbing coating, purpose-made pallet, fan, steam vent, support and needs dry cereal.The back side of described solar heat-collection plate is provided with the heat pipe fixed frame, and being equipped with many on the framework has the heat pipe of certain angle with the framework horizontal plane; The face that described heat pipe fixed frame is pressed close to solar heat-collection plate is whole metallic plate, and an end of heat pipe has small part pass-out metallic plate.The heat pipe section of described metallic plate sunny side and pass-out metallic plate all scribbles heat absorbing coating; The other end of described heat pipe is fixed on the part framework on metallic plate opposite; On the described heat pipe fixed frame fan is installed also, purpose-made pallet is placed on above the heat pipe; Described movable boxboard hangs over each face of heat pipe fixed mount, namely forms drying box, and the movable boxboard at drying box top is provided with steam vent; Described support is arranged on the bottom of drying box, after solar heat-collection plate obtains heat, press close to the heat pipe section of the metallic plate of heat pipe fixed frame of solar heat-collection plate and pass-out metallic plate owing to scribbling heat absorbing coating, whole heat pipe is heated up rapidly, and flash heat transfer, making by movable boxboard and form temperature rising in the drying box, the purpose-made pallet on the heat pipe is put into cereal, fan stirs the air that has heated up in the drying box, and the cereal on the purpose-made pallet is dried fast.

Beneficial effect of the present invention:

The cereal of putting on the drying box purpose-made pallet that this drier forms by movable boxboard can be quickly dried, saves time, cereal laborsaving, that be dried do not pollute, because temperature is higher in the drying box, and effectively sterilization.

Description of drawings:

Fig. 1 is structural representation of the present invention;

Fig. 2 is the demonstration graph of Fig. 1.

Wherein 1. solar heat-collection plate 2. heat pipe 3. the heat pipe fixed frame 4. movable boxboard 5. heat absorbing coating 6. purpose-made pallet 7. fan 8. steam vent 9. support 10. need dry cereal.

The specific embodiment:

Among Fig. 1 Fig. 2, the present invention it have solar heat-collection plate 1. to have the heat pipe fixed frame 3. the many heat pipes that certain angle arranged with the framework horizontal plane to be arranged 2. on the framework and heat pipe is many rows in its back side, the face that framework is pressed close to solar heat-collection plate is whole metallic plate, one end of heat pipe has a little part pass-out metallic plate, the heat pipe section of the sunny side of metallic plate and pass-out metallic plate scribbles heat absorbing coating, on the part framework on the other end fixed metal plate opposite of heat pipe, fan also is installed 7. on the framework, 6. purpose-made pallet is placed above the heat pipe, each outer face of heat pipe fixed frame mounts the drying box that 4. movable boxboard has just formed this solar heat tubular type grain dryer like this, steam vent is 8. on the movable boxboard at drying box top, support is below the movable boxboard of drying box bottom, and 10. cereal be placed in the purpose-made pallet.

The course of work of the present invention is:

Cereal 10. put into solar heat tubular type drier and be the drying box that formed by movable boxboard purpose-made pallet 6. in, purpose-made pallet is placed on heat pipe fixed frame heat pipe 3. and 2. goes up, after 1. solar heat-collection plate receives sunlight and obtains heat, press close to the metallic plate of heat pipe fixed frame of solar heat-collection plate and the heat pipe section of pass-out metallic plate, because scribbling heat absorbing coating 5. can heat up rapidly, the heat pipe flash heat transfer, make temperature rising in the drying box casing, 7. fan stirs the air of the temperature that raise in the drying box, cereal namely is dried, in dry run, 8. the moisture of cereal discharge from steam vent, 9. support is arranged on below the movable boxboard of drying box bottom, is used for firm grain dryer, has so just realized the function of this solar heat tubular type grain dryer.
