Solar air heat collecting oven

Abstract

The invention provides a solar air heat collecting oven. The solar air heat collecting oven has the beneficial effects that fluidity of air in the oven is high, heating is even, and the drying effect is good. The solar air heat collecting oven comprises an oven body (1) and a solar heat collecting device. The solar heat collecting device comprises heat collecting pipes (3) and an insulting box (5). The insulting box (5) is provided with an air outlet pipe (8). An air inlet pipe (4) is arranged in the insulting box (5) and is in sealing connection with the insulting box (5). An air outlet cavity (26) is formed between the air inlet pipe (4) and the insulting box (5) and communicated with the air outlet pipe (8). The air inlet pipe (4) is provided with a plurality of branch pipes (9). After the branch pipes (9) penetrate out of the insulting box (5), the stretching parts are sleeved with the heat collecting pipes (3) respectively, and the heat collecting pipes (3) are in sealing connection with the insulting box (5). The air outlet pipe (8) is connected with a first draught fan (10) connected with the oven body (1).

Description

technical field [0001] The invention relates to the technical field of solar energy application, in particular to a solar air heat collecting oven. Background technique [0002] The oven is a drying and heating device, which can be widely used in electromechanical, chemical, plastic and other industries, and can also be used in scientific research units to bake, dry, cure, and sterilize various products and samples. The heating of the electric heater is used to realize the drying of the product. In actual operation, the product to be dried is placed in the box, and then heated by the heater to dry and evaporate the moisture in the product. In actual operation, some multi-layer sheets When drying shaped products, it is often necessary to place a material rack in the oven box, and then place the products layer by layer and horizontally overlapped on the material rack for drying. However, due to the limitations of the existing oven structure design, the oven box The temperatur...

[0002] The oven is a drying and heating device, which can be widely used in electromechanical, chemical, plastic and other industries, and can also be used in scientific research units to bake, dry, cure, and sterilize various products and samples. The heating of the electric heater is used to realize the drying of the product. In actual operation, the product to be dried is placed in the box, and then heated by the heater to dry and evaporate the moisture in the product. In actual operation, some multi-layer sheets When drying shaped products, it is often necessary to place a material rack in the oven box, and then place the products layer by layer and horizontally overlapped on the material rack for drying. However, due to the limitations of the existing oven structure design, the oven box The temperature in different areas of the body is often slightly different, so when the size of the product to be dried is large, the temperature in different areas of the product is often different, and because the air flow between each layer of products is relatively small, this causes each layer of product Part of the temperature cannot be evenly controlled, so that the generated water vapor cannot be removed in time, which greatly affects the baking effect. The oven is the most widely used equipment in people's daily production and life. Although the structure is relatively simple, it can consumes a lot of energy

Therefore, people have been researching solar heat collection drying equipment, but due to the structural limitation of solar heat collectors, its heat transfer efficiency is low, and it cannot absorb heat to the maximum extent, resulting in poor drying effect. It has not been widely used so far, so a kind of The air inside the oven has strong fluidity, uniform heating, and good drying effect.
