Description

Technical Field

[0001] The invention belongs to the technical field of silicon carbide smelting, and in particular relates to a smelting furnace for smelting silicon carbide from biomass. Background Art

[0002] Silicon carbide is an organic substance, which is mainly made of quartz sand, petroleum coke, sawdust and other raw materials through high-temperature smelting in a resistance furnace. It has the advantages of great hardness, good conductivity and so on. In the smelting process of silicon carbide, the smelting furnace is one of the most important smelting equipment. The smelting furnace is used to heat various raw materials at high temperature to smelt them into silicon carbide.

[0003] The existing document with publication number CN117663781A discloses a silicon carbide smelting furnace that can improve the first-grade silicon carbide yield, including a furnace bottom, and an environmentally friendly sealed furnace wall surrounded by refractory bricks above the furnace bottom and sealed with cement, wherein the furnace bottom is made of refractory bricks with a microchannel structure, and the smelting furnace also includes: an air duct arranged in the lower layer of the furnace bottom.

[0004] However, there are the following defects in use:

[0005] 1. The silicon carbide smelting furnace disclosed in the above document, when in use, the above document mentions that the furnace loading area is divided into a heat preservation material area, a resistance material area, a first area, a second area, a third area and a fourth area, the first area is the furnace bottom area, the second area is the furnace top area, the third area is the area adjacent to the furnace wall, and the fourth area is the other areas of the smelting furnace except the first area, the second area, the third area, the heat preservation material area and the resistance material area, and the raw materials are laid on the first area, the second area, the third area and the fourth area, but because the first area, the second area, the third area and the fourth area are all built with refractory bricks, it is not convenient to repair and replace the raw material placement structure when it is partially damaged;

[0006] 2. The silicon carbide smelting furnace disclosed in the above document, when in use, the above document mentions that the furnace bottom is surrounded by refractory bricks and sealed with cement, and the furnace bottom is made of refractory bricks containing microchannels, and the microchannels run from the top surface of the refractory bricks to the bottom surface of the refractory bricks. An air duct is provided in the lower layer of the furnace bottom, and the air duct is connected to the microchannel. The raw materials are smelted through the sealed space surrounded by the furnace bottom and the furnace wall, but it lacks a structure for automatically leveling the raw materials, thereby affecting the smelting effect due to the uneven distribution of the raw materials;

[0007] 3. The silicon carbide smelting furnace disclosed in the above document, when in use, the above document mentions that the two sides of the longitudinal furnace wall are furnace heads, the furnace heads are equipped with silicon carbide smelting heating electrode ends, the electrode ends are connected to the transformer, the heating electrode ends are installed through the furnace heads, and the smelting furnace is heated by the heating electrode ends. However, during use, since the position of the heating electrode ends in the smelting furnace is fixed, the temperature in various parts of the smelting furnace is uneven, which in turn affects the smelting effect.
