Abstract

The invention discloses an overturning type vacuum sintering furnace for producing luminescent material. The overturning type vacuum sintering furnace comprises a furnace body and an overturning mechanism; a first mounting plate and a second mounting plate are mounted in the furnace body; a sintering cavity is formed between the first mounting plate and the second mounting plate; an opening communicating with the sintering cavity is formed in the side part of the furnace body; a furnace lid is mounted at the opening; the overturning mechanism comprises a driving piece, a first rotary ring, a second rotary ring and a plurality of sintering material grooves for placing sintering material; the first rotary ring is rotatably mounted on the first mounting plate; the second rotary ring is rotatably mounted on the second mounting plate; the driving piece is used for driving the first rotary ring and the second rotary ring to synchronously rotate in the same direction; the sintering material grooves are formed in the circumferential direction; and the two ends of the sintering material grooves are movably connected with the first rotary ring and the second rotary ring in a matching manner.According to the overturning type vacuum sintering furnace, the first rotary ring and the second rotary ring jointly drive a plurality of sintering material grooves to rotate in the sintering cavity,so that the material is uniformly heated and sintered to meet the temperature requirement for the material during the sintering process.

Description

technical field [0001] The invention relates to the technical field of luminescent material production, in particular to an overturning vacuum sintering furnace for luminescent material production. Background technique [0002] Vacuum sintering furnace is a device used for sintering various materials in a vacuum environment. The workpiece powder and powder compact are heated at an appropriate temperature, and the connection between particles is realized by means of atomic migration. The purpose of vacuum sintering is to compact the porous powder to form an alloy with certain structure and properties. Before the sintering furnace is opened, the inside of the sintering furnace needs to be evacuated. [0003] There is a large temperature difference inside the existing vacuum sintering furnace, and the temperature difference between the upper, lower, left and right sides of the furnace is relatively large, especially after the material is placed in the furnace, the temperature ...
