Description

Technical Field

[0001] The utility model relates to the technical field of bone china tunnel kilns, in particular to a heat-insulating bone china tunnel kiln. Background Art

[0002] Tunnel kiln is a tunnel-like kiln built with refractory materials, thermal insulation materials and building materials, equipped with kiln cars and other vehicles. It is a modern continuous firing thermal equipment. Bone china was invented by the British in 1794 and got its name because of the addition of bone meal of cattle, sheep and other herbivorous animals (preferably cattle bone meal) to its clay. The color of bone china is a natural milky white color unique to natural bone meal. Generally speaking, porcelain containing 25% bone meal in the raw materials can be called bone china. It is internationally recognized that the bone meal content should be higher than 40%. The best bone china generally contains 45% high-quality cattle bone meal. Among them, the bone meal content is more than 40%, and the color of the utensils is more milky white, which is a high-end bone china. Among them, the bone china tunnel kiln is a tunnel kiln specially made for bone china as the name suggests.

[0003] However, the existing tunnel kiln has a certain insulation structure on the outer surface of the kiln body, which is mainly composed of a ceiling board, a refractory brick layer, a rock wool layer and a perlite layer. The ceiling board, the refractory brick layer, the rock wool layer and the perlite layer are sequentially attached from bottom to top, but the insulation effect is still not ideal, and the kiln mouth of the tunnel kiln is generally designed to be open, so a certain amount of heat will flow out from the opening, causing further heat loss.
