Microwave and electricity hybrid heating high temperature push plate kiln

Abstract

The invention discloses a microwave and electricity hybrid heating high temperature push plate kiln, which comprises a feeding transitional cabin (3), an inlet microwave inhibitor (26), a microwave heating temperature-raising area furnace body (6), an electrical heating temperature-raising area furnace body (4), a microwave heating heat-preserving area furnace body (7), a slow cooling area furnace body (9), a sharp cooling area furnace body (10), an outlet microwave inhibitor (27) and a discharging transitional cabin (11). Due to the microwave and electricity hybrid heating mode, the defects that a temperature raising speed is low because a part of substances to be burnt have low microwave absorbing capability in a low temperature state, and a manufactured piece cracks due to an overhigh glue expelling speed in the process of heating the manufactured piece by using pure microwave can be overcome, so that the microwave and electricity hybrid heating high temperature push plate kiln hasthe advantages of high heating speed, high production efficiency, high product quality, environment friendliness and obvious energy-saving effect compared with the conventional kiln.

Description

technical field [0001] The invention relates to a pusher kiln, in particular to a high-temperature pusher kiln heated by microwave and electric mixing. Background technique [0002] Microwave energy is known as "the second flame of mankind", and microwave energy application technology has been defined as "new generation technology in the 21st century", "advanced preparation technology of new materials" and "future space heating technology" in developed countries in the world. Based on the microwave heating mechanism, which is different from conventional kilns, it is caused by the internal friction of the material caused by the movement of polarized particles and the forced vibration, and the direct coupling of phonons to generate heat. The material itself is directly used as a heating body. High, the product is heated evenly, the product quality is good, and the energy utilization rate is high, which has obvious advantages in energy saving compared with conventional electric...

Problems solved by technology

However, some special ceramic materials have poor ability to absorb microwaves at low temperatures. Direct heating with microwaves at low temperatures takes longer than conventional electric heating. At the same time, because some ceramic products contain a large amount of organic or inorganic glue, they can be directly heated by microwaves. Causes the deglue to be too fast, and the product is easy to crack
