Abstract

The invention discloses an eccentric air heating furnace for heating foods, tea, medicines, and the like. The air heating furnace structurally comprises a furnace body lower part (1), a furnace body middle part (2), a furnace body upper part (3) and a furnace body top part (4) and comprises four layers from inside to outside, i.e. a combustion chamber (5), a warm air space layer (6), an exhaust space layer (7) and a cold air space layer (8), wherein the furnace body lower part (1) comprises an air inlet (9), a coal cinder chamber (10) and an exhaust port (11), a fire grate (12) is arranged between the furnace body middle part (2) and the furnace body lower part (1), the innermost face of the furnace body middle part (2) is provided with a fireproof wall (13), the furnace body middle part (2) and the furnace body upper part (3) are totally called as the combustion chamber (5), the combustion chamber (5) and the exhaust space layer (7) at the top of the furnace body are mutually communicated through a flue (14), and the warm air space layer and the cold air space layer are sealed and communicated through an upper cover (15). The air heating furnace is mainly characterized in that the cold air space layer of the furnace body lower part (1) is provided with an eccentric air uniform plate, and air entering the furnace is uniformly preheated in an improved mode to absorb heat emitted by the exhaust space layer (7) to the maximum limit so that the heat efficiency is effectively improved.

Description

technical field

[0001] The invention relates to a hot air generating device, which is mainly used for drying and heating of medicine, grain, medicine, tea and other foods, and belongs to the field of food machinery. Background technique

[0002] At present, the structure of the hot blast stoves on the market is relatively simple, without the device of eccentric air uniform plate, the distance between the air uniform hood and the heating layer is consistent at different positions, which is convenient and simple to manufacture, but it causes the temperature on one side of the furnace body to increase. High, low temperature on one side, the heat in the flue layer is not fully absorbed, and the thermal efficiency is low. The main reason is that when the air blows into the cold air from the air inlet through the fan, the wind pressure near the air inlet is relatively large and the wind speed is high, while the position far away from the air inlet has low pressure and slow wind sp...

Embodiment Construction

[0015] In the eccentric hot blast stove of the present invention, the furnace body of the energy-saving hot blast stove is divided into three parts from bottom to top: the lower part of the furnace body (1), the middle part of the furnace body (2), the upper part of the furnace body (3) and the top of the furnace body (4) , the hot blast stove is divided into four layers from the inside to the outside: the combustion chamber (5), the warm air space layer (6), the flue gas space layer (7) and the cold air space layer (8), and the lower part of the furnace body (1) includes the air inlet (9), cinder chamber (10) and smoke outlet (11), fire grate (12) is between body of heater middle part (2) and body of heater bottom (1), and body of heater middle part (2) is because fuel burns The part has the highest temperature, so there are refractory bricks (13) in the innermost layer of the middle part of the furnace body (2), and the middle part of the furnace body and the upper part of th...
