Description

Technical Field

[0001] The invention relates to the technical field of sintering equipment, in particular to a continuous sintering equipment and a use method thereof. Background Art

[0002] As a commonly used hot processing sintering equipment in industrial production, kilns are widely used in many fields such as ceramics, glass, and metallurgy. The state of the burning flame in the kiln has a crucial impact on product quality, energy consumption, and production efficiency. The flame spray gun provides high temperature to melt the raw materials and other sintered materials into glass liquid, and the high-temperature glass liquid is cooled to a temperature range suitable for molding in the cooling part. After that, it is output for glass molding. In the sintering of glass liquid, continuous feeding processing is required.

[0003] Conventional sintering equipment often lacks an effective control mechanism for the feeding process, making it difficult to achieve continuous and uniform input of raw materials. The discontinuity and unevenness of the feeding may cause local temperature changes in the kiln, affecting the softening and decomposition process of the glass raw materials and reducing the quality of the glass liquid. At the same time, the flue gas extraction position is reasonably planned, so that when the flue gas is directly extracted from the main body of the kiln, a large amount of heat is lost. In addition, the filter is prone to clogging in the process of intercepting particulate matter, and lacks a sustainable cleaning mechanism, so that the filtration efficiency of the filter decreases with the increase of use time, affecting the flue gas treatment effect, which is not conducive to the stable sintering of the kiln. In view of the above problems, a continuous sintering equipment and a method of use are proposed. Summary of the invention

10. A method for using the continuous sintering equipment according to claim 1, characterized in that: The following steps are involved: S1. The prepared raw materials are fed into the kiln through the feeding mechanism (300), and the flame spray gun (102) sprays flames to burn in the kiln. In the initial stage of melting, the temperature rises to 800-1000° C., the raw materials begin to soften and decompose, and emit gases such as carbon dioxide, releasing a large amount of heat, so that the temperature in the kiln gradually rises. As the temperature further rises to 1500-1600° C., the raw materials are completely melted into uniform glass liquid; S2, the driving member works, the fan (203) works, negative pressure is generated in the treatment tube (202), smoke is sucked, the filter (217) and the catalyst layer (218) cooperate to remove dust particles in the smoke, and under the action of the catalyst, ammonia or other reducing agent can be sprayed into the treatment tube (202) to reduce nitrogen oxides into nitrogen and water; S3, the glass liquid in the furnace is stably output, and the treated smoke is output to the shifting member, which drives the star-shaped shifting member to work and assists the input of raw materials.
