Problems solved by technology
Well-type furnaces are generally relatively large, and the parts are placed in it for heating. Because the heating source is not evenly distributed inside the well-type furnace, it often leads to uneven heating of parts, which affects the process, and the batch quality is not uniform.
In order to deal with this defect, a fan is installed on the furnace cover of some well-type furnaces to balance the temperature in the furnace by blowing air. Balance effect is not obvious

The invention relates to a novel pit furnace which comprises a furnace wall, a furnace base for sealing the bottom of the furnace wall and a furnace cover covering the top of the furnace wall. A heating element is arranged on the inner wall of the furnace wall; a bearing seat is arranged on the furnace seat; a bearing seat air channel is formed between the bearing seat and the furnace wall; a plurality of airflow holes are formed in the bearing seat; air inlets of the airflow holes are formed in the side wall of the bearing seat; air outlets of the airflow holes are formed in the top surface of the bearing seat; a furnace tank with upper and lower openings is placed on the bearing seat; a furnace tank air channel is formed between the furnace tank and the furnace wall; a plurality of fans and wind shields are arranged on the furnace cover, and the fans are separated by the wind shields, so that the interference of wind among the fans is prevented; an air deflector is arranged on the inner wall of the furnace cover below the fan; an air return hole is formed in the air deflector, and the fan blade is located above the air return hole; and an air guide channel is formed among the furnace cover, the air baffle and the air guide plate. The device has the advantages that gas flow internal circulation can be formed in the pit furnace, so that the temperature in the pit furnace is balanced, and gas components are consistent.
Description
Technical field: [0001] The invention relates to the technical field of heating furnaces, in particular to a novel well-type furnace. Background technique: [0002] Well-type furnaces are widely used in industrial production and manufacturing, such as heat treatment of parts, putting parts into the well-type furnace for heating and other processes to obtain better performance. Well-type furnaces are generally relatively large, and parts are placed in it for heating. Because the heating source is not evenly distributed inside the well-type furnace, it often leads to uneven heating of parts, which affects the process and causes inconsistent batch quality. In order to deal with this defect, a fan is installed on the furnace cover of some well-type furnaces to balance the temperature in the furnace by blowing air. The balance effect is not obvious. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of...
