Abstract

The invention relates to the technical field of heating and specifically discloses an in-furnace jet flow heating device. The device includes an induced draught fan, an air heating cavity, and triangle injection cavities, the induced draught fan is arranged on the top of a furnace, hot-air collection cavities are arranged around the induced draught fan, the hot-air collection cavities are arrangedin the furnace body, the air heating cavity is arranged under the induced draught fan, the top of the air heating cavity clings to the bottom of the hot-air collection cavities, the triangle injection cavities are arranged under the bottom of the air heating cavity, and the hot-air collection cavities communicate with the triangle injection cavities. The range of application of the jet heating device is wide; the hot air generated after heating is sucked by adopting the induced draught fan and enters the triangle injection cavities from the collection cavities through conduction pipes, and the cool air is then sucked again to perform heating, so that repeated cycle utilization is realized, and the resource is saved; heating uniformity of workpieces is guaranteed by adopting the triangle injection cavities, and the heating effect on the workpieces is ensured.

Description

technical field

[0001] The invention belongs to the technical field of heating, in particular to a jet flow heating device in a furnace. Background technique

[0002] Heating equipment is generally a device consisting of a heating element and accessories. In our daily parts production process, parts often need to be heated. With the advancement of technology, jet heating technology has gradually appeared. Jet heating is to spray heated gas with a certain pressure through a nozzle of a certain shape, and directly A method of heating the material surface. The jet heating technology has the advantage of high heating efficiency. The commonly used jet heating equipment is to heat the air in the heating chamber, and the heated hot air is sprayed onto the workpiece through the nozzle. This heating equipment is easy It causes the workpiece to be heated unevenly, and the effect of energy saving and environmental protection cannot be achieved, so we need to design a jet device that c...
