Abstract

The invention discloses a fully-closed high temperature microwave sintering roller kiln, which aims to overcome the shortcomings of high noise, relatively poorer tightness and proneness to the occurrence of kiln arching of the conventional sintering kiln which is a gear drive mechanism. The fully-closed high temperature microwave sintering roller kiln comprises a closed kiln body consisting of a top plate, side plates and a bottom plate. Multi-layer fiberboards are arranged on the two sides and top part of the kiln body. A roller bed is arranged on the bottom plate of the kiln body, and is provided with a push plate for conveying materials. The push plate is driven by a roller bed drive system arranged in a cavity of the kiln body. The fully-closed high temperature microwave sintering roller kiln has a simple structure, low manufacturing cost, high tightness, high product sintering efficiency, high sintering quality and a wide sintering temperature range, is energy-saving, environmentally-friendly, safe and reliable and avoids the phenomenon of kiln arching.

Description

technical field [0001] The invention relates to a microwave kiln, in particular to a fully enclosed microwave high-temperature sintering roller kiln. Background technique [0002] Existing electric sintering furnaces all adopt external gear transmission mechanism, which has poor sealing performance and high investment cost. Due to electric sintering, resistance heating is generally used, and materials or other products are sintered through heat conduction and heat radiation. Since most of the heat in the radiation and conduction process is not absorbed by the sintered material, the sintering efficiency is low. The uniformity of the material is poor; the electric sintering kiln adopts a gear transmission mechanism, the transmission noise is large, and the airtightness is poor, so the heat is easily lost in the form of heat radiation, which further reduces the use of sintering power and causes energy waste; Moreover, the gear transmission requires high requirements and a larg...
