Furnace body of atmosphere protection three-pushed-slab kiln

Abstract

The invention discloses a furnace body of an atmosphere protection three-pushed-slab kiln. The furnace body comprises a furnace shell, a refractory material brick body and a heating device. The refractory material brick body comprises guide rails and guide blocks, wherein the guide rails and the guide blocks are used for carrying and pushing push plates and saggers. The guide rails and the guide blocks penetrate a kiln cavity and extend out of the kiln cavity. The three rows of pushed slabs located on the same transverse position are spaced through the guide blocks. The furnace body has the beneficial effects of being high in production efficiency, large in yield, even in sintering, stable in pushing, high in energy utilization rate, capable of saving energy, environment-friendly and the like.

Description

technical field [0001] The invention mainly relates to the field of sintering equipment, in particular to a furnace body of an atmosphere-protected three-push plate kiln. Background technique [0002] With the rapid development of the new energy industry, the lithium battery industry has become a hot spot today, and the lithium battery material is a key factor determining its performance. The demand for lithium battery materials has increased sharply, and efficient large-scale industrial production is urgently needed. The pusher kiln is a continuous sintering equipment commonly used in the field of lithium battery material preparation. In order to obtain good product quality, ensure that the material is sintered evenly, and the performance meets the specified requirements, it is necessary to adjust the atmosphere and temperature of the pusher kiln cavity so that the product is sintered in a uniform and stable atmosphere and temperature. [0003] The structure of the existi...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing pusher kiln for sintering lithium battery materials is a double pusher or single pusher kiln. The number of pusher plates and saggers pushed each time is small, and its production efficiency is low and the output is small.

[0005] 2. The push plates of the double-push plate kiln are placed side by side during the push process. Therefore, the interference and dislocation caused by the friction of the push plate of the existing double-push plate kiln during the push process lead to arch plates and kiln blocking.

[0006] 3. The process gas of the existing atmosphere-protected pusher kiln is directly connected to the furnace cavity through an intake pipe. When the width of the furnace cavity increases, the structure is complex, and the amount of material sintered is large, the gas and temperature in the furnace are uneven and unstable. Lead to uneven sintering of the material, and the performance cannot meet the specified requirements

[0007] 4. The high-temperature waste heat gas in the cooling zone of the existing atmosphere protection pusher kiln is directly discharged, and because of the requirements of the sintering process, forced cooling is often used, resulting in a great waste of energy, and energy recycling cannot be achieved

[0008] 5. The shell structure of the existing push plate kiln generally adopts a single-layer shell, so it is impossible to realize the recycling of high-temperature waste heat gas in the cooling zone

However, the disadvantage of the pusher kiln with the above structure is that the problem of high energy consumption of the pusher kiln can only be solved by improving the material configuration on the refractory masonry, and cannot solve other existing defects of the pusher kiln
