Problems solved by technology

[0002] During the heat treatment process of solid powder particles, in order to ensure the uniform heat treatment effect between the powders, the powder particles are generally stirred by stirring equipment, and the powder particles are displaced in the sintering furnace by stirring to ensure that the powder particles in each position Uniform heating effect improves the pass rate of products after heat treatment; however, these sintering furnace bodies with stirring are generally a sealed overall structure, and the sintering furnace needs intermittent feeding and discharging during the working process, which cannot be continuously Not only the work efficiency is low, but also the heat utilization rate is relatively low
And once the stirring device is not used, it is easy to cause uneven sintering, which seriously affects the sintering effect of the material

Abstract

The invention relates to a material guiding device for material sintering and a material sintering furnace comprising the material guiding device. The material guiding device for material sintering comprises a shell with a hollow structure, wherein the top of the shell enables materials to be dispersed and fall down along the periphery of the shell, the top of the shell is of a conical tip structure, or the top of the shell is of a curved surface structure, and the shell is provided with a first through hole for hot air to penetrate through. The material sintering furnace comprising the material guiding device comprises a cylindrical furnace body which is vertically arranged, wherein the material guiding device which can enable the materials to fall off in a scattered mode is arranged in a hearth, a material guiding hopper is further arranged above the material guiding device, the small-diameter end of the material guiding hopper is close to the material guiding device, and an auxiliary ignition area is formed by a gap between the material guiding hopper and a furnace wall; a calcining table is further arranged below the material guiding device and is of an umbrella-shaped structure, and a main ignition area is formed below the calcining table. The material sintering furnace comprising the material guiding device is unique in structure, a stirring device is not needed, the materials can be fully sintered, and the heat utilization rate is high; the sintering furnace is vertically arranged, the materials naturally move downwards under the action of gravity, sintering is completed, and continuous production can be achieved.
