Description

Technical Field

[0003] Mullite is a high-quality refractory material, which mainly includes high-purity fused mullite, ordinary fused mullite, all-natural bauxite concentrate sintered mullite and light-burned mullite.

[0004] Sagger is a kind of kiln equipment. In the process of firing ceramics, in order to prevent the destruction and contamination of the body and glaze by gases and harmful substances, the ceramics and the body are placed in a container made of refractory materials for baking. This container is called a sagger, also known as a box.

[0005] Mullite sagger is one of the commonly used kiln tools. The processing technology of mullite sagger is as follows: (1) first put part of the mullite mixed raw materials into a mixer, mix, stir and crush, then add a binder and water and stir again, and finally add the remaining raw material particles in sequence to finally obtain a mixed slurry; (2) pour the mixed slurry into a forming mold placed on a vibration table, turn off the vibration table after completion, demould after 5-8 hours, and then place it on a flat surface to dry naturally to obtain the unfired bricks; (3) The unfired bricks are loaded into the kiln and sintered at 1550℃-1600℃.

[0006] However, the existing mullite saggers are mostly manually fed during mixing and stirring, which requires manual time and then feeds the materials, greatly occupying the labor force; therefore, a feeding device in the refractory material processing process is now proposed, and a feeding device with an adjustable raw material feeding time and automatic feeding is designed.
