High sintering roller way kiln

Abstract

The invention discloses a high sintering roller way kiln which comprises a kiln body, a heating system, a measurement and control system, an exhaust system and a transmission system, wherein a furnace chamber of the kiln body is divided into a water discharge area, a pre-heating area, a sintering area and a cooling area, the heating system comprises a magnetron microwave heating system and an electric heating system which are arranged in the furnace chamber, a microwave head of the microwave heating system is installed in a microwave source energy feedback port of the kiln body and faces the furnace chamber, the electric heating system is installed on the pre-heating area and on the upper side and lower side of the sintering area, and the transmission system penetrates through the furnace chamber of the kiln body to form closed-loop transmission. The high sintering roller way kiln is easy to operate and maintain, the quality of sintered materials is high, efficient and energy-saving microwave heating and electric heating can be carried out at the same time for high sintering, and microwave heating and electric heating can exist in the same heating area.

Description

technical field [0001] The invention relates to a roller kiln, in particular to a high-temperature sintered roller kiln in which microwave and electric heating are used simultaneously to replace the traditional heating method. Background technique [0002] Microwave high-temperature sintering technology is a new technology that has been emerging in recent years. This heating technology belongs to the internal heating method, that is, the product itself absorbs microwave energy and then heats up as a whole. The energy utilization rate is extremely high, which is different from the traditional external heating method. It uses the special wave band of microwave to couple with the basic fine structure of the material to generate heat. The dielectric loss of the material makes the material as a whole heated to the sintering temperature to achieve densification. It is a new method for rapidly preparing high-quality traditional materials and new functional materials. The method is ...

AI Technical Summary

Problems solved by technology

However, judging from the current domestic and foreign market conditions, due to insufficient microwave power density and difficult microwave coupling and matching, existing microwave heating equipment is mainly used for low-temperature microwave sterilization, vulcanization and other industries such as food, medicine, wood, etc., and is really used for industrial production. Industrial-grade large-scale microwave high-temperature sintering kilns have not been manufactured and developed so far, and traditional electric heating kilns with high energy consumption are still mainly used

In addition, the existing microwave and electric hybrid heating kilns are mainly heating in sections, that is, the microwave heating section and the electric heating section in the kiln are relatively independent, and no real mixing has been realized.
