Device for continuously sintering material product by microwave and realization thereof

The invention relates to a device for microwave continuous sintering of material products, which comprises a heating cavity, a microwave generator, a chargingline and a vacuumlead, a feeder arranged over the heating cavity and a feed-out implement arranged below the heating cavity. The feeder and the feed-out implement are both of two layers, wherein, the upper layer of the feeder is a rotary table and the lower layer is a fixed table, while the upper layer of the feed-out implement is a fixed table and the lower layer is a rotary table. The rotary table and the fixed table are respectively provided with a hole for silica crucible passing through when the two relatively moves until the holes align. The device can finish feeding, charging, vacuum pumping, pre-heating, microwave sintering, cooling and discharging, thus realizing microwave continuous sintering of the material products and continuous sintering of non-oxides and a plurality of oxides in the heating cavity. The device not only has simple structure, but also fast sintering rate without environmental pollution.
